Description

Technical Field

[0001] The invention belongs to the technical field of agricultural and animal husbandry machinery, and in particular relates to a straw bale cutting and collecting device. Background Art

[0002] Forage is the basis for the development of livestock and poultry production, especially the production of herbivorous livestock. Forage not only contains various nutrients necessary for livestock, but also contains crude fiber that is particularly important for maintaining the health of ruminant livestock, which is irreplaceable by grain and other feeds. When the planted forage reaches the harvest season, in order to facilitate transportation and reduce storage space, the harvested forage and crop straw are usually mechanically baled into bales. Before the bales enter the subsequent production links such as chopping, crushing, and feeding, the binding ropes wrapped around the bales need to be cut off for unbundling. The existing unbundling method uses manual cutting of the binding ropes, and then the binding ropes are manually pulled out after cutting, which has low work efficiency and high labor intensity.

[0003] Based on this, there is an urgent need for a straw bale cutting and rope collecting device to fill the gap in this field. Summary of the invention

[0004] In view of various deficiencies in the prior art, a straw bale cutting and rope collecting device is proposed to solve the technical problems of low work efficiency and high labor intensity in the prior art of manually cutting and drawing ropes.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A straw bale cutting and collecting device, comprising:

[0007] A bale conveying unit, which is used to convey the bale located above it;

[0008] A rope cutting unit, comprising a cutting knife, wherein the cutting knife is embedded in the inside of the straw bale conveying unit and is used for cutting the binding rope under the straw bale;

[0009] And a rope collecting unit, which is arranged above the straw bale conveying unit, and the rope collecting unit includes a hook tooth plate and a turning plate. After the binding rope is cut, the hook tooth plate hooks the binding rope and gathers it at the turning plate, and the turning plate drives the binding rope to rotate, so that the binding rope is separated from the straw bale.

[0010] The technical solution is further configured such that the bale conveying unit comprises a plurality of sub-conveying units which are transmission-connected, and an installation space for accommodating the cutter is reserved between adjacent sub-conveying units.

[0011] The technical solution is further configured that the cutting knife includes a rotatable fixed cutting knife, and the blade of the fixed cutting knife is parallel to the conveying direction of the bale conveying unit.

[0012] The technical solution is further configured that the cutter includes a movable cutter, the blade of the movable cutter is perpendicular to the conveying direction of the bale conveying unit, and the movable cutter can move along the conveying direction perpendicular to the bale conveying unit.

[0013] The technical solution is further configured such that the movable cutter is transmission-connected to a lifting assembly, and the lifting assembly drives the movable cutter to rise and fall relative to the bale conveying unit.

[0014] The technical solution is further configured as follows: the movable cutting knife is rotatably mounted on a mounting seat via a cantilever, a limiting groove inclined relative to its central axis is provided on the cantilever, the lifting assembly comprises a linear moving element and a sliding member, the sliding member supports the groove wall of the limiting groove, and the linear moving element drives the sliding member to realize lifting and lowering of the movable cutting knife during linear movement.

[0015] The technical solution is further configured as follows: the rope collecting unit is arranged on a support frame, the support frame is arranged across the top of the straw bale conveying unit, and the rope collecting unit can move along a conveying direction perpendicular to the straw bale conveying unit.

[0016] The technical solution is further configured such that the rope collecting unit is transmission-connected to a first driving element, and the first driving element adjusts a pitch angle of the rope collecting unit relative to the support frame.

[0017] The technical solution is further configured such that the rope collecting unit is transmission-connected to a second driving element, and the second driving element drives the rope collecting unit to rise and fall relative to the supporting frame.

[0018] The technical solution is further configured that a plurality of rope hooking teeth are evenly distributed on the circumference of the hook tooth disk, the outer cover of the hook tooth disk is provided with a disk shell, and the disk shell is provided with a slot for accommodating the rope hooking teeth;

[0019] The disk shell is arranged in an involute shape, and during the rotation of the hook tooth disk, the portion of the hook rope tooth embedded in the slot gradually decreases until the hook rope tooth is separated from the slot, and the binding rope hooked by the hook tooth disk can slide down along the disk shell under the action of its own weight.

[0020] The technical solution is further configured as follows: a rope support rod is provided on the flip disk, the rope support rod extends to the slot and is offset relative to the hook tooth disk in the slot, and the binding rope sliding down along the disk shell gathers at the rope support rod.

[0021] The technical solution is further configured such that a movable spring plate which can rotate in one direction is provided at the end of the rope support rod adjacent to the disk shell, and the movable spring plate can be deflected under the action of the binding rope driven by the hook tooth disk to avoid obstruction of the binding rope.

[0022] The technical solution is further configured such that the end of the rope support rod is provided with a mounting groove with a reverse limit, the end of the movable spring plate can be rotatably embedded in the mounting groove, and the notch of the mounting groove is provided with an elastic member;

[0023] When the binding rope that rotates synchronously with the hook rope teeth applies thrust to the movable spring plate, the elastic part produces elastic deformation, and the movable spring plate rotates unidirectionally along the thrust direction. After the thrust disappears, the elastic deformation causes the movable spring plate to reset. After the binding rope slides down along the disk shell to the movable spring plate under the action of its own weight, the installation groove with reverse limit can prevent the movable spring plate from rotating in the opposite direction and causing the binding rope to fall off.

[0024] The technical solution is further configured that a rope pressing rod is also provided on the overturning plate;

[0026] When the rope collecting unit stops moving, the rope pressing rod is in a horizontal state parallel to the rope supporting rod, and the binding rope sliding down along the disk shell is gathered between the rope supporting rod and the rope pressing rod.

[0027] The technical solution is further configured that a limit rod and a limit position for limiting the position of the limit rod are provided on the side of the rope pressing rod;

[0028] When the limiting rod is in the limiting position, the limiting rod applies a supporting force to the rope pressing rod, so that the rope pressing rod is in an inclined state;

[0030] The technical solution is further configured that the rope collecting unit further includes a mounting frame, the flip plate can be flipped relative to the mounting frame, and the flip plate has a self-rotation function;

[0031] After the binding rope sliding down the disk shell gathers between the rope support rod and the rope pressure rod, the flip disk flips 90° clockwise relative to the mounting frame to evolve to the first state, the flip disk starts the self-rotation function, and the rope support rod and the rope pressure rod wind the binding rope;

[0032] After the binding rope is wound, the turning plate turns 180 degrees from the first state to the second state, and the binding rope falls off from the rope supporting rod and the rope pressing rod under the action of its own weight.

[0033] The technical solution is further configured such that the rope collecting unit can rotate relative to the support frame, and the support frame can move along a conveying direction parallel to the bale conveying unit.

[0034] The beneficial effects of the present invention are:

[0035] By setting a rope cutting unit to cut off multiple binding ropes on the straw bale, and by setting a rope collecting unit, the cut binding ropes can be picked up, rotated and drawn out, so that the binding ropes can be automatically collected, thereby completing the separation of the binding ropes from the straw bale. The high degree of automation can reduce the intensity of manual work and increase the speed of unbundling the straw bales. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0052] According to an embodiment of the present invention, a straw bale cutting and collecting device is provided. Figure 1 , Figure 2 as well as Figure 7 ,include:

[0053] A bale conveying unit 100, which is used to convey a bale 200 located above it;

[0054] A rope cutting unit 300, comprising a cutting knife, wherein the cutting knife is embedded in the inside of the bale conveying unit 100 and is used for cutting the binding rope under the bale 200;

[0055] And a rope collecting unit 400, which is arranged above the bale conveying unit 100, and the rope collecting unit 400 includes a hook tooth plate 401 and a flip plate 403. After the binding rope is cut, the hook tooth plate 401 hooks the binding rope and gathers it at the flip plate 403. The flip plate 403 drives the binding rope to rotate, causing the binding rope to be separated from the bale.

[0056] It should be noted that, by setting up a rope cutting unit 300 to cut off multiple binding ropes on the straw bale 200, and by setting up a rope collecting unit 400, the cut binding ropes are picked up, rotated and pulled out, so that the binding ropes are automatically collected, thereby completing the separation of the binding ropes from the straw bale 200. The degree of automation is high, which can reduce the intensity of manual work and increase the speed of unbundling straw bales.

[0057] In the straw bale cutting and collecting device of this embodiment, please refer to Figures 1 to 3 The bale conveying unit 100 includes a plurality of transmission-connected sub-conveying units, and an installation space for accommodating the cutter is reserved between adjacent sub-conveying units.

[0058] It should be noted that the multiple sub-conveyor units are arranged in a straight line in sequence and are connected by a synchronous belt or chain. The bale conveyor unit driving element 101 is used to drive the multiple sub-conveyor units to operate synchronously to convey the bale 200. At the same time, an installation space for accommodating a cutter is reserved at the junction of the front and rear sub-conveyor units. During the conveying process of the bale 200, the cutter cuts the binding rope under the bale 200. In addition, a cover plate is buckled above the installation space, and the top of the cutter is exposed to the cover plate, which can prevent grass from entering the installation space.

[0059] In the straw bale cutting and collecting device of this embodiment, please refer to Figures 1 to 3 The cutting knife includes a rotatable fixed cutting knife 301 , and the blade of the fixed cutting knife 301 is parallel to the conveying direction of the bale conveying unit 100 .

[0060] It should be noted that the fixed cutter 301 is driven to rotate by the fixed cutter driving element, and the rotation speed of the fixed cutter 301 is greater than the conveying speed of the bale conveying unit 100. The fixed cutter 301 can be located at any position within the width range of the bale conveying unit 100. Preferably, the fixed cutter 301 is located at the central axis of the bale conveying unit 100. During the conveying process of the bale 200, the fixed cutter 301 sequentially cuts the binding ropes perpendicular to the conveying direction of the bale conveying unit 100.

[0061] In the straw bale cutting and collecting device of this embodiment, please refer to Figures 1 to 3 The cutting knife includes a movable cutting knife 302 , the blade of the movable cutting knife 302 is perpendicular to the conveying direction of the bale conveying unit 100 , and the movable cutting knife 302 can move along the conveying direction perpendicular to the bale conveying unit 100 .

[0062] It should be noted that a movable cutter driving element 303 is provided on the bale conveying unit 100, and the movable cutter 302 is driven by the movable cutter driving element 303 to move along a conveying direction perpendicular to the bale conveying unit 100. During the movement, the movable cutter 302 cuts the binding ropes parallel to the conveying direction of the bale conveying unit 100 in sequence.

[0063] In the straw bale cutting and collecting device of this embodiment, please refer to Figures 1 to 4 The movable cutter 302 is in transmission connection with a lifting assembly, and the lifting assembly drives the movable cutter 302 to rise and fall relative to the bale conveying unit 100 .

[0064] It should be noted that, in the working state, the lifting assembly drives the movable cutting knife 302 to rise, causing the top of the movable cutting knife 302 to be exposed above the installation space, thereby facilitating cutting the binding rope; in the idle state, the lifting assembly drives the movable cutting knife 302 to descend, causing the movable cutting knife 302 to be completely stored in the installation space, thereby avoiding accidental injury.

[0065] In the straw bale cutting and collecting device of this embodiment, please refer to Figures 1 to 5 The movable cutting knife 302 is rotatably mounted on the mounting seat 309 via a cantilever 304. A limiting groove 306 inclined relative to the central axis is provided on the cantilever 304. The lifting assembly includes a linear moving element 305 and a sliding member 307. The sliding member 307 supports the groove wall of the limiting groove 306. The linear moving element 305 drives the sliding member 307 to move linearly to realize the lifting of the movable cutting knife 302.

[0066] It should be noted that the movable cutter driving element 303 is connected to the mounting seat 309 in a transmission manner to realize the linear movement of the mounting seat 309. The reciprocating linear movement of the mounting seat 309 is realized by the forward and reverse rotation of the movable cutter driving element 303; one end of the cantilever 304 is connected to the mounting seat 309, and the other end thereof is connected to the movable cutter 302. At the same time, a tension spring is arranged between the middle part of the cantilever 304 and the mounting seat 309; the linear moving element 305 is connected to the sliding member 307 through the screw pair 308. During the linear movement of the sliding member 307 driven by the linear moving element 305, under the action of the tension spring, the sliding member 307 contacts different parts of the limiting groove 306. Since the limiting groove 306 is inclined relative to the central axis of the cantilever 304, when the sliding member 307 contacts different parts of the limiting groove 306, the movable cutter 302 performs a lifting movement.

[0067] In the straw bale cutting and collecting device of this embodiment, please refer to Figure 1The rope collecting unit 400 is disposed on a support frame 500 , and the support frame 500 is arranged above the bale conveying unit 100 . The rope collecting unit 400 can move along a conveying direction perpendicular to the bale conveying unit 100 .

[0068] It should be noted that the rope collecting unit 400 is erected above the bale conveying unit 100 through the support frame 500. When the rope collecting unit 400 moves along the conveying direction perpendicular to the bale conveying unit 100, the cut binding rope is picked up, rotated and pulled out from above the bale 200.

[0069] In the straw bale cutting and collecting device of this embodiment, please refer to Figure 1 as well as Figure 6 The rope collecting unit 400 is in transmission connection with the second driving element 800 , and the second driving element 800 drives the rope collecting unit 400 to rise and fall relative to the supporting frame 500 .

[0070] It should be noted that a movable seat 110 is provided on the support frame 500, and the second driving element 800 is located on the movable seat 110; the rope collecting unit 400 is installed on the fixed seat 900 through the connecting rod 700, and the second driving element 800 is connected to the fixed seat 900 through a screw pair; the second driving element 800 is started, and under the action of the screw pair, the fixed seat 900 is raised and lowered along the support frame 500 to adapt to bales of different specifications.

[0071] In the straw bale cutting and collecting device of this embodiment, please refer to Figure 1 as well as Figure 6 The rope collecting unit 400 is transmission-connected to the first driving element 600 , and the first driving element 600 adjusts the pitch angle of the rope collecting unit 400 relative to the support frame 500 .

[0072] It should be noted that the rope collecting unit 400 is rotatably connected to the connecting rod 700. At the same time, a first driving element 600 is also arranged between the fixed seat 900 and the rope collecting unit 400. As the first driving element 600 extends and retracts, the rope collecting unit 400 rotates around the hinge point between it and the connecting rod 700 to adjust the pitch angle of the rope collecting unit 400 relative to the support frame 500, so as to facilitate the hook tooth plate to pick up the binding rope on the grass bale 200.

[0073] In the straw bale cutting and collecting device of this embodiment, please refer to Figure 1 as well as Figure 7 A plurality of rope hook teeth 412 are evenly distributed on the circumference of the hook tooth disc 401, and a disc shell 402 is provided on the outer cover of the hook tooth disc 401. The disc shell 402 is provided with a slot 410 for accommodating the rope hook teeth 412;

[0074] The disk shell 402 is configured to be in an involute shape. During the rotation of the hook tooth disk 401, the portion of the hook rope tooth 412 embedded in the slot 410 gradually decreases until the hook rope tooth 412 is separated from the slot 410. The binding rope hooked by the hook tooth disk 401 can slide down along the disk shell 402 under the action of its own weight.

[0075] It should be noted that the hook tooth disk 401 is connected to the hook tooth disk driving element 407 by transmission, so that the hook tooth disk 401 rotates; the disk shell 402 is set as an arc structure, and the slot 410 extends from the bottom of the arc structure to the top thereof; during the rotation of the hook tooth disk 401, the hook rope tooth 412 picks up the cut binding rope and enters the slot 410 from the bottom of the arc structure. At this time, the binding rope is located on the outside of the disk shell 402; the hook rope tooth 412 applies a dragging force to the binding rope, and the hook rope tooth 412 rotates synchronously with the binding rope. As the part of the hook rope tooth 412 embedded in the slot 410 gradually decreases, until the hook rope tooth 412 is separated from the slot 410, the dragging force of the hook rope tooth 412 on the binding rope disappears, and the binding rope can slide down along the disk shell 402 under the action of its own weight. In addition, the strength of the grass is lower than the strength of the binding rope, and the hook tooth disk 401 will break the grass when it rotates, and the grass hooking phenomenon will not occur.

[0076] In the straw bale cutting and collecting device of this embodiment, please refer to Figures 1 to 8 A rope support rod 404 is provided on the flip disk 403 , and the rope support rod 404 extends to the slot 410 and is offset relative to the hook tooth disk 401 in the slot 410 , and the binding rope sliding down along the disk shell 402 gathers at the rope support rod 404 .

[0077] It should be noted that rope support rods 404 are provided on both sides of the slot 410 . The rope support rods 404 extend to the slot 410 to receive the binding ropes sliding down along the disk shell 402 .

[0078] In the straw bale cutting and collecting device of this embodiment, please refer to Figures 1 to 9 A unidirectionally rotatable movable spring plate 413 is provided at the end of the rope support rod 404 adjacent to the disk shell 402. The movable spring plate 413 can be deflected under the action of the binding rope driven by the rope hook tooth 412 to avoid obstruction to the binding rope.

[0079] It should be noted that when the rope hook tooth 412 drives the binding rope to rotate, the binding rope applies a thrust to the movable spring plate 413 that blocks its rotation. The movable spring plate 413 rotates unidirectionally under the thrust to allow the binding rope to pass through and avoid obstruction to the binding rope.

[0080] In the straw bale cutting and collecting device of this embodiment, please refer to Figures 1 to 12The end of the rope support rod 404 is provided with a mounting groove 415 with a reverse limit, the end of the movable spring plate 413 can be rotatably embedded in the mounting groove 415, and the notch of the mounting groove 415 is provided with an elastic member 414;

[0081] When the binding rope rotating synchronously with the hook rope tooth 412 applies a thrust to the movable spring plate 413, the elastic member 414 generates elastic deformation, and the movable spring plate 413 rotates unidirectionally along the thrust direction. Fig.12 After the thrust disappears, the elastic deformation causes the movable spring plate 413 to reset, see Fig.10 After the binding rope slides down along the disk shell 402 to the movable spring plate 413 under the action of its own weight, the mounting groove 415 with reverse limit can prevent the movable spring plate 413 from rotating in the reverse direction and causing the binding rope to fall off.

[0082] Preferably, the elastic member 414 can be a leaf spring or a torsion spring.

[0083] In the straw bale cutting and collecting device of this embodiment, please refer to Figures 1 to 12 , a rope pressing rod 405 is also provided on the turning plate 403;

[0084] When the rope collecting unit 400 moves along the conveying direction perpendicular to the bale conveying unit 100, the rope pressing rod 405 is in an inclined state relative to the rope supporting rod 404, and an open structure is formed between the rope supporting rod 404 and the rope pressing rod 405, so that the binding rope sliding down along the disk housing 402 is gathered in the open structure formed by the rope supporting rod 404 and the rope pressing rod 405;

[0085] When the rope collecting unit 400 stops moving, the rope pressing rod 405 is in a horizontal state parallel to the rope supporting rod 404 , and the binding rope sliding down along the disk housing 402 is gathered between the rope supporting rod 404 and the rope pressing rod 405 .

[0086] It should be noted that, when the rope collecting unit 400 moves along the conveying direction perpendicular to the bale conveying unit 100, the rope hooking teeth 412 drive the binding rope to rotate, and an open structure is formed between the rope supporting rod 404 and the rope pressing rod 405, so as to facilitate receiving the binding rope sliding down from the disk shell 402; after the rope collecting unit 400 stops moving, the rope pressing rod 405 is in a horizontal state parallel to the rope supporting rod 404, and the rope supporting rod 404 and the rope pressing rod 405 form a clamping force on the binding rope.

[0087] In the straw bale cutting and collecting device of this embodiment, please refer to Figures 1 to 12 A limit rod 406 and a limit position 411 for limiting the position of the limit rod 406 are provided on the side of the rope pressing rod 405;

[0088] When the limiting rod 406 is in the limiting position 411, the limiting rod 406 applies a supporting force to the rope pressing rod 405, so that the rope pressing rod 405 is in an inclined state;

[0089] When the limiting rod 406 is separated from the limiting position 411, the supporting force applied by the limiting rod 406 to the rope pressing rod 405 disappears, so that the rope pressing rod 405 is in a horizontal state.

[0090] It should be noted that an inverted L-shaped limit groove is provided on the limit position 411, and the limit rod driving element can drive the limit rod 406 to rise, fall and rotate, so as to cause the limit rod 406 to be embedded in or out of the inverted L-shaped limit groove; a torsion spring is provided between the rope pressing rod 405 and the flip plate 403, and after the supporting force applied by the limit rod 406 to the rope pressing rod 405 disappears, the rope pressing rod 405 is in a horizontal state under the action of the torsion spring.
