Description

Technical Field

[0001] This utility model relates to the field of agricultural and livestock machinery technology, and in particular to a device for unbundling round balers of dry corn stalks. Background Technology

[0002] Dry yellow straw has always been a major raw material for livestock farming (mainly cattle farming). To facilitate storage and transportation, straw is usually bundled. When feeding livestock, manual unbundling and packaging removal are required.

[0003] The weight of a whole bale of straw is quite large. If the packaging is removed on the ground, the straw cannot be moved as a whole. However, when moving the round bales of straw by forklift, it is very inconvenient to unbundle them manually. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a corn stalk round bale unbundling device, which solves the technical problem of the inconvenience of manual unbundling.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] This utility model provides a corn stalk bale unbale device, including a stalk bale placement frame that is horizontally and detachably fixed to the equipment, a guillotine mounting frame that is vertically arranged on the upper end of the stalk bale placement frame, a guillotine body that is rotatably connected to the top of the guillotine mounting frame and cuts the outer packaging of the stalk bale radially, and a drive unit that is located on the upper end of the stalk bale placement frame and drives the guillotine body to rotate. The guillotine body includes two blade handles that are rotatably connected to the guillotine mounting frame and a blade head that is connected to the ends of the two blade handles. Cutting teeth are evenly spaced along the length direction on the lower end of the blade head.

[0009] This utility model provides a corn stalk bale unbundling device. When using this device, the stalk bale is placed on the upper end of the stalk bale placement rack. Then, the guillotine body is driven to rotate by the drive component until the cutting teeth on the lower end of the blade cut into the outer packaging of the stalk bale, thereby creating a long slit at the upper end of the outer packaging. The stalk bale is then pushed onto the conveyor belt for movement. This solution makes the corn stalk bale unbundling process more convenient, faster, and safer.

[0010] Optionally, the tool holder is positioned by extending and retracting along its length.

[0011] By designing the handle to be telescopic and positionable along its own length, the handle can move the blade head to adjust the cutting position, making the unbundling device adaptable to various sizes of straw bales, thus making it more convenient.

[0012] Optionally, the handle includes a lower handle body connected to the guillotine mounting bracket and an upper handle body coaxially slidably inserted into one end of the lower handle body away from the guillotine mounting bracket, and a positioning bolt is vertically threaded to the side end of the lower handle body, which penetrates into the interior of the lower handle body and abuts against and positions the upper handle body.

[0013] By coaxially sliding the upper handle into the lower handle and positioning it with a positioning bolt, the length of the handle can be extended or retracted at will, making it more convenient.

[0014] Optionally, the cutter head includes two blades that are closely spaced and staggered, with the two blade halves sliding alternately along the length direction.

[0015] By setting the blade head to have two staggered sliding blades, when the inertia of the chaff cutter body cannot directly cut the packaging of the straw bales, the two blades move in an alternating manner in conjunction with the lower cutting teeth, thus cutting the outer packaging of the straw bales more smoothly and conveniently.

[0016] Optionally, each of the two blade handles has a horizontally arranged staggered insert at the end away from the guillotine mounting bracket, and each of the two blade halves has a staggered sleeve for the staggered insert to be inserted at the end away from each other. A spring is coaxially mounted on the staggered insert, and one end of the spring is coaxially connected to one end of the staggered sleeve.

[0017] By inserting the misaligned insert into the misaligned sleeve and connecting them with a spring, the two blade halves can move to a certain extent along the length direction under the pull of the spring, thus making the cutting smoother.

[0018] Optionally, the lower end of the cutting tooth is sharp, and the two ends of the cutting tooth are cutting edges.

[0019] By making the lower end of the cutting teeth sharp and setting cutting edges on both sides, the cutting teeth can either penetrate and cut the outer packaging by inertia or move in an alternating manner to cut it, making it more convenient.

[0020] Optionally, the cross-section of the misaligned insert and the misaligned sleeve along their length direction is square.

[0021] By setting the cross-section of the staggered insert and the staggered sleeve to square, the blades can only move in an alternating manner, which is more stable.

[0022] Optionally, the upper surface of the straw bale placement rack is horizontally provided with a pusher to push the cut-out straw bales away from the straw bale placement rack.

[0023] By using a horizontally sliding pusher at the top of the straw bale placement frame, the pusher can work with the conveyor belt to push the unbundled straw bales into the conveyor belt for transport, making it more convenient.

[0024] Optionally, the lower middle part of the guillotine mounting frame has a push hole flush with the upper surface of the straw bale placement frame. The pusher slides into the push hole, and the working end face of the pusher is arc-shaped. The arc end face of the pusher is smoothly embedded in the side end face of the guillotine mounting frame and the upper surface of the straw bale placement frame, respectively.

[0025] By opening a push hole in the middle of the lower end of the guillotine mounting frame, the pusher is embedded in the push hole. The end face of the pusher is set as an arc end face. The two sides of the arc end face smoothly connect to the side end face of the guillotine mounting frame and the upper end face of the straw bale placement frame, so that when the pusher pushes the straw bale, it can better partially shovel into the lower end of the straw bale and push the straw bale.

[0026] (III) Beneficial Effects

[0027] The beneficial effects of this utility model are as follows: When using the corn stalk round bale unbundling device of this utility model, the round bale of straw is placed on the upper end of the round bale of straw placement frame, and then the guillotine body is driven to rotate by the drive component until the cutting teeth at the lower end of the blade head cut into the outer packaging of the round bale of straw, thereby making a long cut at the upper end of the outer packaging of the round bale of straw. Then the round bale of straw is pushed onto the conveyor belt for movement. This solution makes the unbundling process of corn stalk round bales more convenient, faster and safer.

[0032] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] The corn stalk bale unbundling device proposed in this embodiment of the invention involves placing the bale on the upper end of the bale placement rack, then driving the guillotine body to rotate until the cutting teeth at the lower end of the blade cut into the outer packaging of the bale, thus creating a long slit at the upper end of the outer packaging. The bale is then pushed onto a conveyor belt for movement. This solution makes the unbundling process of corn stalk bales more convenient, faster, and safer.

[0034] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0035] Reference Figure 1 and Figure 2 A corn stalk bale unbundling device includes a stalk bale placement frame 1 that is horizontally and detachably fixed to the equipment by bolts, a guillotine mounting frame 2 that is vertically welded to the upper end of the stalk bale placement frame 1, a guillotine body 3 that is rotatably connected to the top of the guillotine mounting frame 2 and cuts the outer packaging of the stalk bale radially along the stalk bale as it rotates, and a drive component 4 that is set at the upper end of the stalk bale placement frame 1 and drives the guillotine body 3 to rotate.

[0036] The guillotine body 3 includes two rotatably connected handles 31 to the guillotine mounting frame 2 and a cutter head 32 connected to the ends of the two handles 31. Cutting teeth 33 are evenly spaced along the length of the lower end of the cutter head 32. The straw bale is placed on the upper end of the straw bale placement frame 1, and then the guillotine body 3 is driven to rotate by the drive component 4 until the cutting teeth 33 at the lower end of the cutter head 32 cut into the outer packaging of the straw bale, thereby making a long slit at the upper end of the outer packaging of the straw bale. The straw bale is then pushed onto the conveyor belt for movement.

[0037] The handle 31 extends and retracts along its length for positioning. The handle 31 includes a lower handle body 311 fixed to the chaff cutter mounting bracket 2 by bolts, and an upper handle body 312 coaxially slidably inserted into the lower handle body 311 at the end away from the chaff cutter mounting bracket 2. A positioning bolt 313, threaded vertically through the lower handle body 311 and abutting against the positioning upper handle body 312, is threaded onto the side end of the lower handle body 311. The extension and retraction of the handle 31 allows the blade head 32 to move, adjusting its cutting position. This makes the unbundling device adaptable to various sizes of straw bales, providing greater convenience.

[0038] The driving component 4 includes two long cylinders that are rotatably connected to the upper surface of the straw bale placement frame 1 near the guillotine mounting frame 2 via a rotating shaft. The piston rod ends of the two long cylinders are rotatably connected to the side of the lower handle 311 via a rotating shaft, thereby driving the entire guillotine body 3 to rotate by extending and retracting the piston rods of the long cylinders.

[0039] The cutter head 32 includes two blades that are closely attached and staggered. The two blade halves slide alternately along the length direction. At the ends of the two upper handles 312 away from the cutter mounting bracket 2, a staggered insert 3121 is welded vertically and horizontally to each other. At the ends of the two blade halves that are far from each other, a staggered sleeve 321 is provided for the staggered insert 3121 to be inserted. The cross-section of the staggered insert 3121 and the staggered sleeve 321 along the length direction of themselves is square. A spring 322 is coaxially mounted on the staggered insert 3121. One end of the spring 322 is coaxially connected to one end of the staggered sleeve 321, and the other end of the spring 322 is connected to one end of the upper handle 312. Under the pull of spring 322, the two blade halves can move to a certain extent along the length direction, so as to cut the outer packaging of the straw bales more smoothly. The middle of the two blade halves is provided with a waist-shaped long hole along its own length direction. The two waist-shaped long holes are aligned and a limiter is inserted inside to limit the collision of the two blade halves, so that the two blade halves can only move in a staggered manner along the length direction.

[0040] The lower end of the cutting tooth 33 is sharp, and the two ends of the cutting tooth 33 are cutting blades 331. The cutting tooth 33 can either penetrate and cut open the outer packaging by inertia, or it can cut open by moving in an alternating manner, which is more convenient.

[0041] The upper surface of the straw bale placement rack 1 is horizontally equipped with a pusher 11 to push the cut-out straw bales away from the rack 1. The lower center of the chaff cutter mounting frame 2 has a push hole 21 flush with the upper surface of the straw bale placement rack 1. The pusher 11 is pushed and slid into the push hole 21 by a cylinder. The working end face of the pusher 11 is arc-shaped, and the arc-shaped end face of the pusher 11 smoothly engages with the side end face of the chaff cutter mounting frame 2 and the upper surface of the straw bale placement rack 1. When pushing the straw bales, the pusher 11 can better partially scoop into the lower end of the straw bales and push them forward.
