Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural and pastoral machinery, and particularly relates to a bale cutting and rope collecting device for grass bales. Background Art

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

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

[0004] In view of the various deficiencies of the prior art, a 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 manual rope cutting and extraction.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0009] And a rope collecting unit arranged above the bale conveying unit. The rope collecting unit includes a tooth hook disc and a turning disc. After the binding rope is cut, the tooth hook disc hooks the binding rope and gathers it at the turning disc, and the turning disc drives the binding rope to rotate, causing the binding rope to separate from the bale.

[0010] This technical solution is further configured such that the bale conveying unit includes a plurality of sub-conveying units connected in transmission, and an installation space for accommodating the cutting knife is left between adjacent sub-conveying units.

[0011] This technical solution is further configured such that the cutting knife includes a rotatable fixed cutting knife, and the cutting edge 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.

[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] This technical solution is further configured such that an installation groove with reverse rotation limit is provided at the end of the support rope rod, the end of the movable elastic plate is rotatably embedded in the installation groove, and an elastic member is provided at the notch of the installation groove;

[0023] When the binding rope that rotates synchronously with the hook rope teeth applies a thrust to the movable elastic plate, the elastic member undergoes elastic deformation, the movable elastic plate rotates unidirectionally along the thrust direction, and after the thrust disappears, the elastic deformation causes the movable elastic plate to reset. After the binding rope slides down along the disc housing to the movable elastic plate, the installation groove with reverse rotation limit can prevent the movable elastic plate from rotating reversely and causing the binding rope to fall off.

[0024] This technical solution is further configured such that a rope pressing rod is further provided on the flipping disc;

[0027] This technical solution is further configured such that a limiting rod and a limiting position for defining the position of the limiting rod are provided on the side surface 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, prompting the rope pressing rod to be in an inclined state;

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

Detailed implementation manners

[0051] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model will be clearly and completely described below in conjunction with the drawings of the present utility model. Based on the embodiments in this application, other similar embodiments obtained by those of ordinary skill in the art without creative efforts shall all fall within the scope of protection of this application. In addition, the directional terms mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only with reference to the directions in the drawings. Therefore, the directional terms used are for illustration rather than to limit the present invention.

[0052] According to an embodiment of the present utility model, there is provided a bale rope cutting and winding device. Please refer to Figure 1 , Figure 2 and Figure 7 , including:

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

[0054] A rope cutting unit 300, which includes a cutting knife, and the cutting knife is embedded in the bale conveying unit 100 and is used to cut the binding rope under the bale 200;

[0055] and a rope collecting unit 400, which is arranged above the bale conveying unit 100. The rope collecting unit 400 includes a toothed disc 401 and a flipping disc 403. After the binding rope is cut, the toothed disc 401 hooks the binding rope and accumulates it at the flipping disc 403, and the flipping disc 403 drives the binding rope to rotate, so as to separate the binding rope from the bale.

[0056] It should be noted that by arranging the rope cutting unit 300 to cut multiple binding ropes on the bale 200, and by arranging the rope collecting unit 400, the cut binding ropes are lifted, rotated and pulled out, so as to realize automatic collection of the binding ropes, thereby completing the separation of the binding ropes from the bale 200. The automation degree is high, which can reduce the manual work intensity and improve the bale untying speed.

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

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

[0059] In the bale rope cutting and collecting device of this embodiment, please refer to Figures 1 to 3 , the cutter includes a rotatable fixed cutter 301, and the cutting edge of the fixed cutter 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 a 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 bale rope cutting and collecting device of this embodiment, please refer to Figures 1 to 3 , the cutter includes a movable cutter 302, the cutting edge of the movable cutter 302 is perpendicular to the conveying direction of the bale conveying unit 100, and the movable cutter 302 can move along the direction perpendicular to the conveying direction of 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 1, the rope winding unit 400 is arranged on the support frame 500, the support frame 500 is spanned above the bale conveying unit 100, and the rope winding unit 400 can move along a direction perpendicular to the conveying direction of the bale conveying unit 100.

[0068] It should be noted that the rope winding unit 400 is erected above the bale conveying unit 100 through the support frame 500. During the movement of the rope winding unit 400 along a direction perpendicular to the conveying direction of the bale conveying unit 100, the bundled rope after being cut is lifted, rotated and drawn out from above the bale 200.

[0069] In the bale cutting and rope winding device of this embodiment, please refer to Figure 1 and Figure 6 , the rope winding unit 400 is in transmission connection with the second driving element 800, and the second driving element 800 drives the rope winding unit 400 to lift relative to the support frame 500.

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

[0071] In the bale cutting and rope winding device of this embodiment, please refer to Figure 1 and Figure 6 , the rope winding unit 400 is in transmission connection with the first driving element 600, and the first driving element 600 adjusts the pitching angle of the rope winding unit 400 relative to the support frame 500.

[0072] It should be noted that the rope winding 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 winding unit 400. Along with the telescoping of the first driving element 600, the rope winding unit 400 rotates around its hinge point with the connecting rod 700 to adjust the pitching angle of the rope winding unit 400 relative to the support frame 500, so as to facilitate the hook teeth disc to pick up the bundled rope on the bale 200.

[0073] In the bale cutting and rope winding device of this embodiment, please refer to Figure 1 and Figure 7 , a plurality of rope-hooking teeth 412 are evenly distributed on the circumference of the hook teeth disc 401, a disc shell 402 is arranged outside the hook teeth disc 401, and a slot 410 for accommodating the rope-hooking teeth 412 is arranged on the disc shell 402;

[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 12, an installation groove 415 with reverse rotation limit is provided at the end of the support rope rod 404, the end of the movable elastic plate 413 is rotatably embedded in the installation groove 415, and an elastic member 414 is provided at the notch of the installation groove 415;

[0081] When the binding rope that rotates synchronously with the hook rope teeth 412 applies a thrust to the movable elastic plate 413, the elastic member 414 generates elastic deformation, and the movable elastic plate 413 rotates unidirectionally along the thrust direction. Please refer to Figure 12 ; after the thrust disappears, the elastic deformation causes the movable elastic plate 413 to reset. Please refer to Figure 10 ; after the binding rope slides down along the disc housing 402 to the movable elastic plate 413 under its own weight, the installation groove 415 with reverse rotation limit can prevent the movable elastic 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 reed or a torsion spring.

[0083] In the hay bale rope cutting and rope collecting device of this embodiment, please refer to Figures 1 to 12 , a rope pressing rod 405 is further provided on the flipping disc 403;

[0084] During the movement of the rope collecting unit 400 along the direction perpendicular to the conveying direction of the hay bale conveying unit 100, the rope pressing rod 405 is in an inclined state relative to the support rope rod 404, and an open structure is formed between the support rope rod 404 and the rope pressing rod 405, so that the binding rope sliding down along the disc housing 402 gathers in the open structure formed by the support rope rod 404 and the rope pressing rod 405;

[0085] When the rope collecting unit 400 is in a stationary state, the rope pressing rod 405 is in a horizontal state parallel to the support rope rod 404, and the binding rope sliding down along the disc housing 402 gathers between the support rope rod 404 and the rope pressing rod 405.

[0086] It should be noted that during the movement of the rope collecting unit 400 along the direction perpendicular to the conveying direction of the hay bale conveying unit 100, the hook rope teeth 412 drive the binding rope to rotate, and an open structure is formed between the support rope rod 404 and the rope pressing rod 405, which is convenient for receiving the binding rope sliding down from the disc housing 402; after the rope collecting unit 400 stops moving, the rope pressing rod 405 is in a horizontal state parallel to the support rope rod 404, and the support rope rod 404 and the rope pressing rod 405 form a clamping force on the binding rope.

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

[0088] When the limiting rod 406 is in the limiting position 411, the limiting rod 406 exerts a supporting force on the rope pressing rod 405, causing the rope pressing rod 405 to be in an inclined state;

[0089] When the limiting rod 406 disengages from the limiting position 411, the supporting force exerted by the limiting rod 406 on the rope pressing rod 405 disappears, causing the rope pressing rod 405 to be in a horizontal state.

[0090] It should be noted that an inverted L-shaped limiting groove is provided on the limiting position 411, and the limiting rod driving element can drive the limiting rod 406 to lift and rotate, so that the limiting rod 406 is inserted into or disengaged from the inverted L-shaped limiting groove; a torsion spring is provided between the rope pressing rod 405 and the flipping disc 403. After the supporting force exerted by the limiting rod 406 on the rope pressing rod 405 disappears, the rope pressing rod 405 is in a horizontal state under the action of the torsion spring.

[0091] In the bale cutting and rope collecting device of this embodiment, please refer to Figures 1 to 12 , the rope collecting unit 400 further includes a mounting frame 416, the flipping disc 403 can flip relative to the mounting frame 416, and the flipping disc 403 has a self-rotation function.

[0092] It should be noted that the flipping disc rotation driving element 408 can drive the flipping disc 403 to rotate self, and the flipping disc flipping driving element 409 can drive the flipping disc 403 to flip relative to the mounting frame 416; after the binding ropes sliding down along the disc shell 402 gather between the rope supporting rod 404 and the rope pressing rod 405, the flipping disc 403 flips 90° clockwise relative to the mounting frame 416 and evolves to the first state. Please refer to Figure 13 , the flipping disc 403 activates the self-rotation function, and the rope supporting rod 404 and the rope pressing rod 405 wind the binding ropes; after the binding ropes are wound, the flipping disc 403 flips 180° from the first state and evolves to the second state. Please refer to Figure 14 , and the binding ropes fall off the rope supporting rod 404 and the rope pressing rod 405 under the action of their own weight.

[0093] In the bale cutting and rope collecting device of this embodiment, please refer to Figure 1 and Figure 6 , Figure 7 , the rope collecting unit 400 can rotate relative to the support frame 500, and the support frame 500 can move along the conveying direction parallel to the bale conveying unit 100.

[0094] It should be noted that a rotating disk is provided below the fixed seat 900. The first driving element 600 and the connecting rod 700 are both arranged between the rotating disk and the mounting frame 416. A rope winding unit rotating driving element 120 for driving the rotating disk to rotate is arranged on the fixed seat 900. After the rope winding unit rotating driving element 120 drives the rope winding unit 400 to rotate 90°, at the same time, the support frame 500 moves along the conveying direction parallel to the bale conveying unit 100, and the hook tooth disk 401 hooks the binding rope in another binding direction.

[0095] During operation, place the bale 200 above the bale conveying unit 100. During the process of the bale conveying unit 100 conveying the bale 200, the rope cutting unit 300 cuts the binding rope below the bale 200. After that, adjust the height and pitching angle of the rope winding unit 400. The rope winding unit 400 moves along the width direction of the bale conveying unit 100. At the same time, the hook tooth disk 401 rotates, the turning disk 403 is in the initial state, the limiting rod 406 is embedded in the limiting position 411, the pressing rope rod 405 is in an inclined state, and the rope hooking tooth 412 picks up and drives the binding rope in the first binding direction to rotate. The binding rope gathers on the rope supporting rod 404. When the rope winding unit 400 moves outside the width of the bale conveying unit 100, the limiting rod 406 disengages from the limiting position 411, the pressing rope rod 405 is in a horizontal state, the turning disk 403 evolves to the first state, and drives the binding rope to rotate and wind itself. After the winding is completed, the turning disk 403 evolves to the second state, and the binding rope falls into the collection basket under the action of gravity. The turning disk 403 evolves to the third state, and the third state is between the first state and the second state. The limiting rod 406 resets and is embedded in the limiting position 411. At this time, the limiting rod 406 is located between the rope supporting rod 404 and the pressing rope rod 405, and the turning disk 403 evolves to the initial state, completing the rope cutting and rope winding operations of the binding rope in the first binding direction. The rope winding unit 400 rotates 90°. At the same time, the support frame 500 drives the rope winding unit 400 to move along the conveying direction parallel to the bale conveying unit 100, and the hook tooth disk 401 hooks the binding rope in the second binding direction. This process will not be elaborated here.

The above description is only the preferred embodiment of the present invention, and it cannot limit the scope of implementation of the present invention. That is, all equal changes and modifications made according to the scope of this application should still fall within the scope covered by the present invention.
