Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a connectable belt of a residual film recovery machine and a production process thereof. Background Art

[0002] The residual film recycling machine is an important equipment for cleaning and recycling residual film in farmland, and is widely used in modern agricultural production. With the continuous improvement of farmland protection awareness and the increasingly stringent environmental protection regulations, the demand for residual film recycling machines has increased significantly. In order to improve the efficiency of farmland residual film recycling, various types of residual film recycling machines have emerged and become an important part of the field of modern agricultural machinery. As one of the core components of the residual film recycling machine, the performance of the spiked belt directly affects the working efficiency and reliability of the recycling machine.

[0003] The existing residual film recycling machine can refer to the Chinese patent with application number 202322794876.5. The spiked belt includes a belt body and spikes passing through the belt. The belts used in the residual film recycling machines on the market are all spiked belts, which are made of high-power V-belts drilled with holes and fixed with spikes, and each residual film recycling machine uses a large amount. The current residual film recycling machine will be damaged prematurely during operation, and the damage is mostly in the form of belt breakage. If the new belt is not replaced in time, the residual film recycling of the cultivated land will not be clean; but the current replacement method requires disassembling the tensioning shaft of the residual film recycling machine and then removing the belt. The replacement is time-consuming and inconvenient, affecting work efficiency.

[0004] The existing belt production process can refer to the Chinese patent application number 201510048783.5, which discloses a belt process method, including the following steps: 1) batching; 2) mixing; 3) calendering; 4) film splicing; 5) adding wire rope molding; 6) vulcanization: pressure vulcanization of the rubber sleeve; 7) grinding after vulcanization demoulding. The one-piece belt produced in this way is punched and spikes are installed to form a spike-tooth belt. The existing spike-tooth belt is used in the residual film recycling machine and is inconvenient to replace. Summary of the invention

[0005] In order to facilitate the replacement of the belt of a residual film recovery machine, the present application provides a connectable belt of a residual film recovery machine and a production process thereof.

[0006] This application provides a residual film recycling machine with a connectable belt adopting the following technical solution: A connectable belt for a residual film recycling machine includes a belt body and a plurality of spike teeth penetrating the belt body, the belt body includes an outer cloth layer, a top rubber layer and a bottom rubber layer, a cord structure is arranged between the top rubber layer and the bottom rubber layer, the cord structure is ring-shaped, the belt body is formed with a sub-end and a female end, the cord structure is formed with a rotating structure at both the sub-end and the female end, a locking assembly is arranged between the sub-end and the female end, and both ends of the locking assembly pass through the rotating structure of the sub-end and the rotating structure of the female end respectively.

[0007] By adopting the above technical solution, the buckle assembly is easier to disassemble and assemble. After disassembly, it is convenient to disconnect the sub-end and the female end of the belt body. The buckle assembly cooperates with the wire rope structure so that more fulcrums of the buckle assembly are on the wire rope structure. This connection method does not damage the wire rope structure, so that the buckle assembly will not fall off the belt body, thereby ensuring the stability of the connection.

[0008] Optionally, the locking buckle assembly includes a sub-lock buckle, a mother lock buckle, a link pin and a connecting shaft. The sub-lock buckle and the mother lock buckle are detachably fixedly connected at one end close to each other through a link pin. The connecting shaft at the sub-end passes through the sub-lock buckle and the rotating structure of the sub-end in sequence and is buried in the belt body. The connecting shaft at the mother end passes through the mother lock buckle and the rotating structure of the mother end in sequence.

[0009] By adopting the above technical solution, the overall structure is relatively simple and the disassembly and assembly are relatively convenient. The connecting shaft is inserted in the rotating structure. When subjected to external force, the force is mainly between the connecting shaft and the rope, rather than between the locking assembly and the rubber. This greatly enhances the tensile strength of the connection, thereby reducing the failure rate of the belt.

[0010] Optionally, the sub-lock buckle includes two oppositely arranged first chain plates, a connecting shaft connects one end of the two first chain plates, and a connecting pin connects the other end of the two first chain plates. The mother lock buckle includes two oppositely arranged second chain plates, the second chain plates are located on the outer sides of the first chain plates, and a shaft sleeve is arranged between the two first chain plates, and the shaft sleeve is sleeved on the connecting pin.

[0011] By adopting the above technical solution, the first chain plate and the second chain plate are connected more stably through the linking pin, the two first chain plates are not easy to get close to each other, and the connection point is more stable.

[0012] Optionally, a bending structure is formed on the first chain plate, the bending structure is located between the link pin and the connecting shaft, and the bending structure is buried in the belt body.

[0013] By adopting the above technical solution, it is convenient to stack the ends of the first chain plate and the second chain plate, so that the first chain plate and the second chain plate are not easy to exceed the overall width of the belt body. At the same time, the bending structure is buried in the belt body, and the connection between the first chain plate and the belt body is more stable.

[0014] Optionally, a reinforcement piece is provided between the two second chain plates, and two ends of the reinforcement piece are respectively fixed to the two second chain plates.

[0015] By adopting the above technical solution, the connection strength of the second chain plates is further guaranteed, and the two second chain plates are not easy to spread outwards.

[0016] Optionally, weight-reducing holes are provided on the reinforcement.

[0017] By adopting the above technical solution, the overall weight is reduced to a certain extent and the cost is saved.

[0018] Optionally, the reinforcing member is embedded in the belt body.

[0019] By adopting the above technical solution, the reinforcing member can be embedded in the belt body, and weight-reducing holes are formed in the reinforcing member to further enhance the connection stability with the belt body.

[0020] A production process of a detachable belt for a residual film recycling machine includes batching, mixing, calendering, splicing, adding wire ropes to form a shape, vulcanizing, and grinding the finished product. A combined assembly process is added between adding wire ropes to form a shape and vulcanizing. First, the formed semi-finished belt is stretched and combined to form two layers, and after folding, the ends are joined together to form a sub-end and a mother-end. At this time, the wire rope structure is two layers and a rotary structure is formed at both the sub-end and the mother-end. A connecting shaft is inserted at the rotary structure of the two layers of semi-finished belts, and the assembled semi-finished belts are vulcanized together to form a finished belt.

[0021] By adopting the above technical solution, the wire rope structure of the finished belt is two layers, further enhancing the strength of the belt body. The connecting shaft directly cooperates with the rotary structure. When subjected to external forces, the force is borne between the connecting shaft and the wire rope structure, greatly enhancing the tensile strength at the connection.

[0022] Optionally, a sub-lock and a mother-lock are respectively installed at the sub-end and the mother-end of the two layers of semi-finished belts, and the connecting shaft is respectively inserted for fixation.

[0023] By adopting the above technical solution, after installing the sub-lock and the mother-lock and then vulcanizing, part of the sub-lock and the mother-lock are embedded in the belt body, further strengthening the connection strength between the sub-lock and the mother-lock and the belt body; at the same time, it is more convenient than installing the sub-lock and the mother-lock after vulcanization.

[0024] Optionally, after the assembly process is completed, a bottom rubber layer with a thickness of 1 mm - 3 mm is cut off.

[0025] By adopting the above technical solution, the thickness of the finished belt body is appropriate.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The lock assembly is relatively convenient to disassemble and assemble, facilitating the replacement of the belt.

[0027] 2. Double-layer wire rope structure, the belt body has higher strength.

[0028] 3. The lock assembly cooperates with the rotary structure. When subjected to external forces, the force is borne between the lock assembly and the wire rope structure, greatly enhancing the tensile strength at the connection. Brief Description of the Drawings

[0033] The following further describes the present application in detail with reference to the Figure 1 - drawings.

[0034] The embodiment of the present application discloses a detachable belt for a residual film recycling machine. Referring to Figure 1 , it includes a belt body 1 and spike teeth. The spike teeth penetrate through the belt body 1. There are multiple spike teeth and they are equidistantly arranged along the length direction of the belt body 1. The belt body 1 includes an outer wrapping layer, a top glue layer, a rope structure 2 and a bottom glue layer. The rope structure 2 is located between the top glue layer and the bottom glue layer. The belt body 1 forms a sub-end and a mother-end. The rope structure 2 is annular. The rope structure 2 is stacked in two layers and rotary structures 21 are formed at both the sub-end and the mother-end. A buckle assembly is arranged between the sub-end and the mother-end. Both ends of the buckle assembly respectively pass through the rotary structure 21 at the sub-end and the rotary structure 21 at the mother-end, so that the rotary structure 21 directly cooperates with the buckle assembly. When subjected to an external force, the force is borne between the buckle assembly and the rope structure 2, greatly strengthening the tensile strength at the connection.

[0035] Referring to Figure 2 and Figure 3 , the buckle assembly includes a sub-buckle 3, a mother-buckle 4, a linking pin shaft 6 and a connecting shaft 5. The sub-buckle 3 includes two relatively arranged first chain plates. The rotary structure 21 is located between the two first chain plates. The connecting shaft 5 at the sub-end passes through the two first chain plates and the rotary structure 21. At this time, the rope bypasses the connecting shaft 5, and one ends of the two first chain plates are also connected through the connecting shaft 5. The mother-buckle 4 includes two relatively arranged second chain plates. The second chain plates are respectively located outside the first chain plates. The connecting shaft 5 at the mother-end passes through the two second chain plates and the rotary structure 21. The connecting shafts 5 at the sub-end and the mother-end, the end of the first chain plate close to the sub-end and the end of the second chain plate close to the mother-end can all be buried in the belt body 1 (not shown in the figure). One end of the sub-buckle 3 close to the mother-buckle 4 is detachably and fixedly connected through the linking pin shaft 6, that is, the connection can be completed by passing the linking pin shaft 6 through the first chain plate and the second chain plate at one time.

[0036] A bushing 7 is sleeved on the connecting pin shaft 6, and the bushing 7 is located between two first link plates. A reinforcing member 41 is arranged between two second link plates. Two ends of the reinforcing member 41 are respectively fixedly connected to the second link plates. A weight-reducing hole 411 is formed in the reinforcing member 41, and the reinforcing member 41 can be embedded in the belt body 1 (not shown in the figure). A bending structure 31 is formed on the first link plate. The bending structure 31 makes one end of the first link plate in contact with the second link plate approach each other and thus be located inside the second link plate. The bending structure 31 is located between the connecting pin shaft 6 and the connecting shaft 5, and the bending structure 31 can be embedded in the belt body 1 (not shown in the figure). The buckle assembly is in the form of a link, with a relatively simple structure, stable connection with the wire rope structure 2, and stable connection itself, being convenient for disassembly and assembly.

[0037] The implementation principle of the detachable belt of the film residue recycling machine in the embodiment of the present application is as follows: When the film residue recycling machine needs to replace the belt, only the connecting pin shaft 6 needs to be removed to open the sub-buckle 3 and the mother-buckle 4, and the belt can be disassembled, which is relatively convenient and fast. The wire rope directly bypasses the connecting shaft 5. When an external force acts, the connecting shaft 5 directly acts on the wire rope, greatly enhancing the tensile strength at the connection.

[0038] A production process for the detachable belt of the film residue recycling machine includes batching, mixing, calendering, splicing, forming with wire ropes, vulcanizing, and grinding into finished products. On the basis of the existing process, a combined assembly process is added between forming and vulcanizing. In the combined assembly process, first, the semi-finished belt after forming with wire ropes is stretched and combined to form two layers. At this time, the semi-finished belt is a flat ring and has two ends. The wire rope structure 2 is in two layers and the two ends form a rotating structure 21. Then, after folding, the ends are joined together to form a sub-end and a mother-end. The connecting shaft 5 is inserted at the rotating structure 21 of the two layers of semi-finished belts. The wire ropes at the actual rotating structure 21 bypass the connecting shaft 5, and then the two layers of stretched and combined semi-finished belts are vulcanized together to form a finished belt. Of course, when installing the connecting shaft 5, the sub-buckle 3 and the mother-buckle 4 can also be installed, and the connecting shaft 5 preliminarily fixes the sub-buckle 3 and the mother-buckle 4 to the semi-finished belt respectively. Because the thickness of the finished belt increases after the semi-finished belts are stretched, combined, and laminated, in order to make the thickness of the finished belt moderate after vulcanization, a bottom rubber layer with a thickness of 1 mm - 3 mm is cut off before vulcanization after the assembly process is completed. By adding a combined assembly process to the existing process, the detachable belt of the film residue recycling machine can be produced, and the process optimization is relatively convenient.

[0039] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
