1. Field of the Invention
This invention relates to an agricultural bagging machine and more particularly to an adjustable anchor wing for an agricultural bagging machine.
2. Description of the Related Art
Agricultural feed bagging machines have been employed for several years to pack or bag silage or the like into elongated plastic bags. Two of the earliest bagging machines are disclosed in U.S. Pat. Nos. 3,687,061 and 4,046,068. In the prior art bagging machines, silage or the like is supplied to the forward or intake end of the bagging machine and is fed to a rotor or the like which conveys the silage into a tunnel on which the bag is positioned so that the bag is filled. As silage is loaded into the bag, the bagging machine moves away from the filled end of the bag in a controlled fashion so as to achieve uniform compaction of the silage material within the bag. In U.S. Pat. No. 4,337,805, silage is forced by means of a rotor from the intake chamber of the machine through the output chamber of the machine and into the agricultural bag with a backstop structure yieldably engaging the closed end of the agricultural bag to resist the movement of the bagging machine away from the filled end of the agricultural bag as silage is forced into the bag. The structure of the '805 patent includes a pair of drums rotatably mounted on the bagging machine with a brake associated therewith for braking or resisting the rotation of the drum with a selected brake force. A cable is wrapped around the drum and is connected to the backstop.
Although the cable drum and backstop structure of the '805 patent and other similar machines do function generally satisfactorily, the cables, which are positioned on opposite sides of the bag, can create openings or holes in the bag which will adversely affect the fermentation process within the bag. A further disadvantage of the cable drum and backstop structure of the devices such as shown in the '805 patent is that the cables must be rewound after the filling of an individual bag. A further disadvantage of the cable drum and backstop structure of the machine such as disclosed in the '805 patent is that a dangerous condition exists should one of the cables break.
In an effort to overcome some of the disadvantages of machines such a disclosed in the '805 patent, an attempt was made in U.S. Pat. No. 4,621,666 to achieve the desired bagging operation while eliminating the need for the cable drum and backstop structure. In the '666 patent, the wheels on the bagging machine were braked to provide the desired resistance to the filling of the bag. Although the brake system of the '666 patent apparently met with some success, it is believed that machines such as disclosed in the '666 patent experience slippage difficulties in wet field conditions which adversely affect the bagging operation. It is also believed that the brake means alone on the bagging machine such as those disclosed in the '666 patent do not achieve the desired compaction of the silage material within the bag.
In applicant's U.S. Pat. No. 5,297,377, a bagging machine is described which has the capability of enabling the density of the silage material to be selectively controlled without the need of an elaborate braking system. In applicant's U.S. Pat. No. 5,297,377, a density control means is described which included a plurality of cables which are positioned in the flow of the silage material being bagged. In order to vary the density of the material in the machine of the '377 patent, more or less cables are employed based on the material being packed. For example, corn silage flows easy and would require more cables while alfalfa packs hard and would use less cables.
In applicant's U.S. Pat. No. 5,425,220, a density control means is described which includes a pair of intersecting cables positioned in the flow of the silage material being bagged. In order to vary the density of the material in the machine of the '220 patent, the relationship of the intersecting or crisscrossing cables is varied. In applicant's U.S. Pat. No. 5,671,594, a fixed beveled press plate is disclosed for use with a density control cable.
Although the use of the density control cables in applicant's previous patents such as U.S. Pat. No 5,671,594 has met with success, the adjustment of the cable sloop takes approximately ten feet of machine movement before the adjusted cable loop becomes completely effective.
An agricultural feed bagging machine is disclosed which comprises a wheeled frame having rearward and forward ends. A tunnel is provided on the wheeled frame and has an intake end for receiving silage material or the like and an output end adapted to receive the mouth of an agricultural bag. A hopper or feed table is provided on the wheeled frame for receiving the material to be bagged and is adapted to supply the same to a feed compression means such as a rotatable rotor which forces the material into the tunnel and into the bag. First and second cables extend rearwardly from the frame into the tunnel and have an adjustable anchor wing assembly operatively connected thereto. The adjustable anchor wing assembly includes a primary hub which is connected to the rearward end of the first cable. A pair of wing members are pivotally secured to the primary hub and may be moved between retracted and extended positions. A center adjustment hub is pivotally connected to the wing members through a linkage for moving the wing members between their retracted and extended positions. The rearward end of the second cable passes through the primary hub and is secured to the center adjustment hub. Forward movement of the fist cable while the second cable is moved rearwardly causes the wing members to be pivotally moved from their extended position to their retracted position. Conversely, rearward movement of the first cable while simultaneously moving the second cable forwardly causes the wing members to be pivotally moved from their extracted position to their extended position As the bagging machine packs material into the bag and the bagging machine moves away from the bagged material, the adjustable anchor wing assembly is pulled through the material being bagged to act as an anchor to hold the machine from rolling ahead prematurely. The anchoring effect of the anchor wing assembly is varied by pivotally moving the wing members between their extended and retracted positions.
It is therefore a principal object of the invention to provide an adjustable anchor wing assembly for use on an agricultural bagging machine.
Still another object of the invention is to provide an adjustable anchor wing assembly for use on an agricultural bagging machine wherein the assembly acts as an anchor in the material being bagged to prevent the bagging machine from rolling ahead prematurely.
Still another object of the invention is to provide an adjustable anchor wing assembly which enables the density of the packed material to be precisely controlled with the adjustment of the adjustable wing assembly being substantially simultaneous.
Yet another object of the invention is to provide an adjustable anchor wing assembly which may be mounted on a conventional agricultural bagging machine without extensive modifications thereof.
Still another object of the invention is to provide an adjustable anchor wing assembly for use on an agricultural bagging machine which is economical of manufacture and durable in use.
These and other objects will be apparent to those skilled in the art.
The numeral 10 refers generally to an agricultural bagging machine such as disclosed in U.S. Pat. No. 5,671,594. Machine 10 includes a wheeled frame 12 having a tunnel 14 mounted thereon upon which is normally positioned the open mouth of a conventional agricultural bag. Although the preferred embodiment includes a wheeled frame, a non-wheeled frame could also be employed. For purposes of conciseness, the power means for driving the various components of the machine will not be disclosed, since the same does not form a part of the invention. The power means could be an engine mounted on the machine or it could be a power takeoff (PTO) shaft connected to a tractor PTO.
For purposes of description, the bagging machine 10 will be described as including a forward end 16 and a rearward end 18. Bagging machine 10 includes a hopper means 20 or other material receiving means, such as a feed table, conveyors or the like, at the forward end thereof which is adapted to receive the material to be bagged from a truck, wagon, etc. A horizontal disposed rotatable rotor 22 of conventional design is located at the lower end of the hopper means 20 for forcing the material to be bagged into the funnel 14 and into the bag in conventional fashion. Although a horizontally disposed rotor is disclosed, it is possible that the types of material compression or compaction means could be employed such as augers, packers, etc.
For purposes of description, frame 12 includes floor 24 located beneath rotor 22 and which extends rearwardly therefrom. Floor 24 is provided with an elongated opening 26 formed in its rearward end. It is to the bagging machine described above that the adjustable anchor wing assembly 28 is mounted. Anchor wing assembly 28 includes a primary or main hub 30 having a central opening 32 extending therethrough. Wing members 34 and 36 are pivotally connected to the opposite sides of hub 30 by bolts 38 and 40, respectively. Links 42 and 44 are pivotally connected to wing members 34 and 36 by bolts 46 and 48, respectively. The other ends of the links are pivotally connected to a center adjustment hub 50 by means of bolts or pins 52 and 54, respectively.
The numeral 56 refers to a first cable having its forward end secured to one end of an elongated arm 58. The other end of cable 5. 6 is secured to primary hub 30, as seen in the drawings. The numeral 60 refers to a second cable which as its forward end secured to the other end of elongated arm 58 and which has its rearward end operatively secured to center adjustment hub 50. As seen in
The adjustable anchor wing assembly of this invention, by being positioned at the rear of the tunnel, causes the assembly of this invention to act as an anchor to hold the machine from rolling ahead prematurely. It is recommended that the wing be positioned no closer to the rotor than four feet, although varying situations may arise wherein it is desirable to more closely position the wing assembly to the rotor. The positioning of the wing assembly to stream through moving mass in a natural taut condition and location, vertically and horizontally. It can be appreciated that the more extended the wing members are, the greater resistance to the machine moving away from the packed bag will be present. When the wing assembly is in its completely closed position, the least amount of packing density will be achieved in the filled bag. When the wing assembly is in its completely extended position, the greatest amount of packing density will be achieved in the filled bag. Thus, the adjustable anchor wing assembly of this invention provides an adjustable density control. The adjustment of the anchor wing assembly is instantaneous and the affect on the density of the material is immediate. When a cable loop is used as the density control means, it takes approximately ten feet of machine movement before the new adjusted cable loop width is completely effective.
During the bagging operation, as the bag is almost filled, the wing assembly of this invention is adjusted to the least amount of width at about ten feet from the intended end of the bag. This gives the wing enough time (distance) to close completely. The closed wing can then be pulled from the packed mass without much power being required and in a manner which does not significantly disturb the packed mass.
Thus it can be seen that a novel adjustable anchor wing assembly has been provided for an agricultural bagging machine which accomplishes at least all of its stated objectives.
