Description

Technical Field

[0001] The present invention relates to the technical field of coix seed harvesters, and in particular to a transmission crawler mechanism of a coix seed whole plant harvester. Background Art

[0002] Job's tears harvester is a kind of agricultural machinery specially used for harvesting Job's tears crops. With the development of agricultural modernization, mechanized harvesting has been widely used in agricultural production, including the harvesting of Job's tears. Mechanized harvesting equipment can replace manual work, which can significantly improve harvesting efficiency, reduce labor costs, and reduce farmers' labor intensity. Specially designed Job's tears harvesters have appeared on the market. These machines include cutting tables, feed ports, crushing wheels, conveyor belts and other components to meet the needs of Job's tears harvesting.

[0003] Among them, the conveyor belt part is mainly used for transferring and transporting the harvested Job's tears to the harvester. There are two main types of conveyor belt structures for existing harvesters, one is the traditional belt conveyor belt, and the other is the crawler conveyor belt. Compared with the traditional belt conveyor belt, the initial investment cost of the conveyor crawler mechanism is higher, but it is more durable and the crawler shoes are not easy to be damaged. The traditional conveyor belt needs to be replaced as a whole after being damaged, while the crawler conveyor belt only needs to replace the crawler shoes at the corresponding position.

[0004] In the prior art, the transmission crawler mechanism in the harvester can be driven by a gear chain transmission method to ensure the stability of the entire transmission crawler mechanism during operation. The track piece is installed on the outside of the transmission chain and moves with the movement of the transmission chain. It is generally connected and fixed by bolt connectors, which makes the subsequent disassembly and maintenance operations of a single track piece cumbersome, requiring frequent installation and disassembly of bolt connectors. Secondly, in the actual harvesting process, the body of the entire harvester will produce high-frequency vibrations due to the operation of various equipment. This vibration is also easy to cause the bolt connectors to loosen, thereby affecting the stability of the track piece installed in the working position. Therefore, the present application provides a transmission crawler mechanism for a whole-plant Job's tears harvester to meet the needs. Utility Model Content

[0005] The technical problem to be solved is to provide a transmission crawler mechanism for a whole-plant coix seed harvester to solve the problems that the existing crawler piece disassembly and maintenance operations are cumbersome and the connecting parts are easily loosened due to the vibration of the equipment during operation.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A conveying crawler mechanism of a whole-plant Job's tears harvester comprises a whole-plant Job's tears harvester and a conveying crawler mechanism, wherein the whole-plant Job's tears harvester is equipped with a processing cabin and a fixed frame, and the conveying crawler mechanism is assembled in the fixed frame, a driving shaft and a driven shaft are sleeved in the fixed frame, and a driving motor for driving the driving shaft to rotate is fixedly installed on the outside of the fixed frame, transmission gears are sleeved on the driven shaft and the driving motor, a transmission chain is sleeved between the two transmission gears, and a track shoe is connected to the outside of the transmission chain; a connecting component is used to fix the relative position between the transmission chain and the track shoe, and the connecting component is connected to the track shoe.

[0008] Optionally, the conveying crawler mechanism is arranged obliquely on the Job's tears whole-plant harvester, the input end of the conveying crawler mechanism is close to the ground, and the output end of the conveying crawler mechanism extends into the processing cabin.

[0009] Optionally, the transmission gear is fixedly connected to the middle of the driven shaft and the drive motor, and the teeth on the outside of the transmission gear are adapted to the shape of the gap between the transmission chain.

[0010] Optionally, a slope is provided on the top of the track shoe, and a groove is provided on the outside of the track shoe.

[0011] Optionally, the connecting assembly includes a connecting seat sleeved on the inner side of the track shoe and a connecting block fixedly connected to the outer side of the transmission chain, and the connecting seat is provided with a plug-in groove matched with the shape of the connecting block.

[0012] Optionally, the connecting seat is T-shaped as a whole, a slide groove adapted to the shape of the connecting seat is opened in the track shoe, and an installation port adapted to the thickness value of the connecting seat is opened on the track shoe, and the installation port is connected to the middle of the slide groove.

[0013] Optionally, a limiting spring sheet is fixedly connected to a surface of the connection seat facing the outer side of the track shoe, a second lightweight groove is provided on the connection seat, and a smooth curved surface is provided at the edge of the second lightweight groove.

[0014] Optionally, the middle portion of the limiting spring piece is X-shaped, and a fixed end is provided on a side of the limiting spring piece close to the inner wall of the track piece, and the fixed end is fixed to the inner wall of the track piece by bolts.

[0015] Optionally, the thickness of the middle part of the limiting spring piece is the same as the height of the inner side of the track shoe, and a first lightweight groove evenly distributed is opened in the middle part of the limiting spring piece, and a first weakened groove and a second weakened groove are arranged on the limiting spring piece.

[0016] Optionally, the first weakening groove is symmetrically distributed between the fixed end and the middle part of the limiting spring piece, and the second weakening groove is symmetrically distributed at the connection between the limiting spring piece and the connecting seat.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting the limiting spring piece and the connecting seat in the connecting assembly, the connection and installation operation between the track piece and the transmission chain is simple and convenient, which facilitates the inspection and maintenance of the track piece. At the same time, the existence of the limiting spring piece can continuously squeeze and limit the connecting seat, so that the connection between the track piece and the transmission chain will not loosen due to vibration during operation.

[0019] By setting a limiting spring piece in the connecting component, on the one hand, the design of the first weakening groove and the second weakening groove on the limiting spring piece can guide the deformation area of ​​the limiting spring piece to ensure the structural stability of the limiting spring piece, and indirectly ensure the fitting contact effect between the connecting seat and the connecting block through the elastic force of the limiting spring piece, thereby further improving the function of the connecting component. On the other hand, the top of the limiting spring piece contacts the top of the inner wall of the track piece, and then forms a structure similar to a reinforcing rib on the inner side of the track piece, thereby improving the structural strength of the track piece during actual use, so that the connecting component can strengthen the structure of the track piece while realizing the connection function.

[0020] By providing the slide groove and the installation opening in the connecting component, when the track piece is damaged and needs to be replaced, the limiting spring piece and the connecting seat in the original track piece can be removed and installed in the new track piece, thereby realizing the reuse of the limiting spring piece and the connecting seat and reducing the replacement cost of the track piece.

[0037] like Figures 1 to 7As shown, this embodiment provides a conveying crawler mechanism of a whole-plant coix seed harvester, including a whole-plant coix seed harvester 1 and a conveying crawler mechanism 3. The whole-plant coix seed harvester 1 is equipped with a processing cabin 2 and a fixed frame 5. The conveying crawler mechanism 3 is assembled with the fixed frame 5. The whole-plant coix seed harvester 1 is used to drive the harvesting equipment to move in the coix seed field. The fixed frame 5 provides a fixed installation position for the conveying crawler mechanism 3. The processing cabin 2 is used for continuing to store and subsequently process the harvested whole-plant coix seed. A driving shaft 6 and a driven shaft 7 are sleeved in the fixed frame 5, and a driving motor for driving the driving shaft 6 to rotate is fixedly installed on the outside of the fixed frame 5. 8. A transmission gear 11 is sleeved on the driven shaft 7 and the driving motor 8. A transmission chain 12 is sleeved between the two transmission gears 11. The outside of the transmission chain 12 is connected with a track piece 9. When the driving motor 8 is working, it can drive the driving shaft 6 to rotate through its driving shaft, and then drive the transmission gear 11 on the driving shaft 6 to rotate, so that after the transmission gear 11 rotates, it drives the transmission chain 12 to operate through its external teeth, and then drives the track piece 9 to follow and move, so as to transfer the harvested whole coix seed; a connecting component is used to fix the relative position between the transmission chain 12 and the track piece 9, and the connecting component is connected to the track piece 9.

[0038] In this embodiment, if Figures 1 to 4 As shown, the transmission crawler mechanism 3 is tilted on the coix seed whole-plant harvester 1, the input end of the transmission crawler mechanism 3 is close to the ground, and the output end of the transmission crawler mechanism 3 extends into the processing cabin 2. The tilted setting of the transmission crawler mechanism 3 can form a height difference between its input end and output end, so that the coix seed at a low place is transferred to a high place and sent from the high place to the processing cabin 2 for stacking. The transmission gear 11 is fixedly connected to the middle of the driven shaft 7 and the driving motor 8, and the teeth on the outside of the transmission gear 11 are adapted to the gap shape between the transmission chain 12. The transmission gear 11 is arranged in the middle of the driven shaft 7 and the driving motor 8 so that the transmission chain 12 and the track shoe 9 have symmetrical structures on their outside, so that when the transmission gear 11 rotates and drives the transmission chain 12 to operate, the transmission chain 12 and the track shoe 9 are evenly stressed, thereby preventing the track shoe 9 from tilting during transportation and causing the coix seed to leak out.

[0039] In this embodiment, if Figures 1 to 4As shown, the top of the track piece 9 is provided with an inclined surface, and the inclined surface provided on the top of the track piece 9 can reduce the area of ​​the top of the track piece 9, and then when the track piece 9 moves to the input end and the output end of the conveying crawler mechanism 3, it avoids the adjacent track pieces 9, so as to avoid the adjacent track pieces 9 from colliding with each other due to the deflection of the transmission chain 12 and causing damage, and the outside of the track piece 9 is provided with a groove 10, and the groove 10 on the outside of the track piece 9 makes the surface of the track piece 9 no longer flat, forming a concave-convex structure, which increases the resistance of the coix seed to slide in the process of transporting the whole coix seed upward, and avoids the coix seed from sliding. During the transportation process, the grains slide and accumulate at the input end of the conveying crawler mechanism 3. The connecting component includes a connecting seat 15 sleeved on the inner side of the track shoe 9 and a connecting block 13 fixedly connected to the outer side of the transmission chain 12. The connecting seat 15 is provided with a plug-in groove 4 that is adapted to the shape of the connecting block 13. The plug-in groove 4 on the connecting seat 15 can be snap-fitted onto the outer side of the connecting block 13, so that a connection is formed between the track shoe 9 and the transmission chain 12, and then the transmission chain 12 can drive the connecting seat 15 to move during the movement, indirectly driving the track shoe 9 to move, thereby realizing the transport of the coix seed by the track shoe 9.

[0040] In this embodiment, if Figures 4 to 6 As shown, the connecting seat 15 is T-shaped as a whole, and a slide groove 16 that matches the shape of the connecting seat 15 is opened in the crawler shoe 9. The top end of the T-shaped structure of the connecting seat 15 is inserted into the slide groove 16. During the sliding process of the connecting seat 15 in the crawler shoe 9, its top end also slides in the slide groove 16, and the sliding of the connecting seat 15 is limited and guided to ensure the stability of the connecting seat 15 during the sliding process, and a mounting opening 17 that matches the thickness value of the connecting seat 15 is opened on the crawler shoe 9, and the mounting opening 17 is connected with the middle part of the slide groove 16. When the crawler shoe 9 is damaged and cannot be used, the connecting seat 15 and the limiting spring piece 14 in the crawler shoe 9 can be removed. After the crawler shoe 9 is disassembled as a whole from the outside of the transmission chain 12, the connecting seat 15 can be easily removed by sliding it to the mounting opening 17, so that the limiting spring piece 14 and the connecting seat 15 can be reused, reducing the replacement cost of the crawler shoe 9 after damage, and making the disassembly operation of the connecting seat 15 simple and convenient.

[0041] In this embodiment, if Figures 5 to 7As shown, the connection seat 15 is fixedly connected to a limiting spring piece 14 on the side facing the outer side of the track shoe 9, and a second lightweight groove 18 is opened on the connection seat 15. When the connection seat 15 is connected and fixed to the connection block 13, the limiting spring piece 14 is in a compressed state, and the corresponding elastic force of the limiting spring piece 14 itself reacts on the connection seat 15 to squeeze and limit the connection seat 15, thereby maintaining the connection and fixation between the connection seat 15 and the connection block 13. In the fixed state, even if the connection between the connection seat 15 and the connection block 13 becomes loose due to vibration, it can be quickly reset under the elastic action of the limiting spring piece 14 to ensure the stability of the connection. A smooth curved surface is provided at the edge of the second lightweight groove 18. The design of the second lightweight groove 18 not only reduces the overall weight of the connection seat 15 and reduces the production cost, but also can form a buckle groove on the connection seat 15, which is convenient for the staff to buckle the second lightweight groove 18 to move the connection seat 15.

[0042] In this embodiment, if Figures 5 to 7 As shown, the middle part of the limiting spring piece 14 is X-shaped, and a fixed end 19 is provided on one side of the limiting spring piece 14 close to the inner wall of the track shoe 9, and the fixed end 19 is fixed to the inner wall of the track shoe 9 by bolts. After the limiting spring piece 14 is integrally sleeved in the track shoe 9, it is connected and fixed to the track shoe 9 by bolts, so as to ensure the fixation of the working position of the limiting spring piece 14. The thickness value of the middle part of the limiting spring piece 14 is the same as the height value of the inner side of the track shoe 9. The thickness value of the middle part of the limiting spring piece 14 makes the top of the limiting spring piece 14 and the top of the inner wall of the track shoe 9 contact each other, forming a structure similar to a reinforcing rib, which can improve the structural strength of the track shoe 9 to a certain extent, so that the track shoe 9 will not be easily deformed when it is hit by foreign objects, and the middle part of the limiting spring piece 14 is provided with a uniformly distributed first lightweight groove 20 The first lightweight groove 20 in the middle of the limiting spring piece 14 is used to reduce the weight of the limiting spring piece 14. In conjunction with the design of the second lightweight groove 18, the entire conveying crawler mechanism 3 is lightweighted to reduce the workload of the drive motor 8. The limiting spring piece 14 is provided with a first weakening groove 21 and a second weakening groove 22. The first weakening groove 21 is symmetrically distributed between the fixed end 19 and the middle of the limiting spring piece 14, and the second weakening groove 22 is symmetrically distributed at the connection between the limiting spring piece 14 and the connecting seat 15. The design of the first weakening groove 21 and the second weakening groove 22 makes the limiting spring piece 14 thinner in thickness and weaker in strength at the position where the two are opened, and it is easier to deform after being subjected to external force, thereby guiding the deformation position of the limiting spring piece 14 to be at the first weakening groove 21 and the second weakening groove 22, thereby ensuring the overall structural shape of the limiting spring piece 14.

[0043] The technical solution provided by the utility model is that when in use, the whole-plant coix seed harvester 1 works and moves in the coix seed field to harvest the coix seeds, and the harvested coix seeds fall on the track shoes 9 and are transferred to the processing cabin 2, the drive motor 8 is started and drives the drive shaft 6 to rotate through its drive shaft, and then drives the transmission gear 11 on the drive shaft 6 to rotate, and after the transmission gear 11 rotates, it drives the transmission chain 12 to operate through its external teeth, and then drives the track shoes 9 outside the transmission chain 12 to follow and move, so as to transport the harvested whole-plant coix seeds and transfer the coix seeds to the processing cabin 2 for subsequent processing.

[0044] When the track shoe 9 needs to be disassembled and repaired, the second lightweight groove 18 on the connecting seat 15 is buckled and pulled toward the outside of the track shoe 9, so that the connecting seat 15 can be driven to slide on the inner side of the track shoe 9 and squeeze the limiting spring piece 14. After the limiting spring piece 14 is subjected to pressure, it is deformed at the first weakened groove 21 and the second weakened groove 22 to adapt to the sliding of the connecting seat 15 in the track shoe 9. After the connecting seat 15 slides in the track shoe 9, the plug-in groove 4 is separated from the outside of the connecting block 13, thereby releasing the connection and fixation between the transmission chain 12 and the track shoe 9, and separating the track shoe 9 from the transmission chain 12.

[0045] If it is found after inspection that the track shoe 9 is not damaged, the track shoe 9 is directly buckled in its original position and pressed in the direction of the transmission chain 12. The connecting seat 15 is squeezed again and slides to compress the limiting spring piece 14. After the plug-in slot 4 moves to the position corresponding to the connecting block 13, the limiting spring piece 14 restores its deformation under the action of its own elastic force, and drives the plug-in slot 4 on the connecting seat 15 to be sleeved on the outside of the connecting block 13, so as to realize the connection and fixation between the transmission chain 12 and the track shoe 9. In the fixed state, the limiting spring piece 14 is still in a compressed state, and the reaction force of the limiting spring piece 14 on the connecting seat 15 is used to continuously squeeze the connecting seat 15, thereby maintaining the connection contact state between the connecting seat 15 and the connecting block 13, and the connection will not be disconnected due to vibration during operation.

[0046] If it is found upon inspection that the track shoe 9 is damaged and cannot be used any more, the limiting spring piece 14 and the connecting seat 15 in the original track shoe 9 are disassembled and taken out from the mounting opening 17. After the limiting spring piece 14 and the connecting seat 15 are integrally mounted in the new track shoe 9, the fixing end 19 is used to connect and fix the new track shoe 9 with the bolt connector. Then the new track shoe 9 is completely mounted and fixed on the outside of the transmission chain 12, thereby completing the operation and inspection and maintenance process of the transmission crawler mechanism of the entire Job's tears whole-plant harvester.

[0047] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the present principle. These improvements and modifications should also be regarded as within the scope of protection of this invention.
