[0115] It should be understood that the first view or the second view in different embodiments is not the same view.

[0116] In particular, the overhauling device, the tire assembly 200 and the shredding assembly 300 are arranged on the mounting frame, the first side of the upper end of the feeding assembly 400 is connected with the first side of the upper end of the shredding assembly 300 through the first connecting mechanism 50, the second side of the upper end of the feeding assembly 400 is connected with the second side of the upper end of the shredding assembly 300 through the second connecting mechanism 60, and the lower end of the feeding assembly 400 is hung on the shredding assembly 300 through the hook assembly 70, so that the feeding assembly 400 and the shredding assembly 300 are connected in up-down and left-right directions, the connection is reliable, and the stability is high; in the hanging working state, the feeding assembly 400 is fixed relative to the shredding assembly 300 through cooperation of the first connecting mechanism 50 and the second connecting mechanism 60, so as to ensure the structural stability during feeding and shredding; in the overhauling, the feeding assembly 400 is vertically rotated relative to the shredding assembly 300 around the hook assembly 70 through cooperation of the first connecting mechanism 50 and the second connecting mechanism 60, so that the feeding assembly 400 and the shredding assembly 300 are arranged in a V shape in a vertical plane, and then the feeding assembly 400 is fixed relative to the shredding assembly 300 through cooperation of the first connecting mechanism 50 and the second connecting mechanism 60, so as to ensure the structural stability during overhauling, thereby the main working components in the feeding assembly 400 and the shredding assembly 300 can be overhauled and maintained; since the shredding assembly 300 is located between the tire assemblies 200, the overhauling difficulty of the main working components in the shredding assembly 300 is increased during the overhauling, the feeding assembly 400 is separated from the hook assembly 70 to be rolling matched with the translation assembly 80, and then the feeding assembly 400 can be rolling translated relative to the shredding assembly 300 on the translation assembly 80 by a preset distance through the first connecting mechanism 50 and the second connecting mechanism 60, at this time, the second side of the feeding assembly 400 is arranged in suspension, and the feeding assembly 400 is horizontally rotated relative to the shredding assembly 300 around the first connecting mechanism 50 by manual driving or mechanical driving, so that the feeding assembly 400 and the shredding assembly 300 are arranged in a side opening in a horizontal plane, so that the main working components in the feeding assembly 400 and the shredding assembly 300 can be overhauled and maintained in the case of increasing the overhauling space and reducing the overhauling difficulty; in the above two overhauling states, the connection relationship between the feeding assembly 400 and the shredding assembly 300 is not completely removed, so the feeding assembly 400 does not need to be moved, and in the process of resetting to the hanging working state, the first connecting mechanism 50 can be taken as an assembly reference for assembly, the assembly difficulty is small, the assembly precision is high, and the assembly speed is fast.The first connecting mechanism 50, the second connecting mechanism 60, the hook assembly 70 and the translation assembly 80 cooperate with each other to provide sufficient maintenance space for the main working components of the feeding assembly 400 and the chopping assembly 300 without completely releasing the connection relationship between the feeding assembly 400 and the chopping assembly 300, thereby reducing the maintenance requirement, reducing the assembly difficulty of the feeding assembly 400 and the chopping assembly 300, improving the assembly precision, improving the maintenance efficiency, improving the practicability, and being suitable for wide promotion and application.

[0144] The suspension device 3 has a left-right symmetrical structure and includes a lifting frame 031, a lifting oil cylinder 032, a limiting rod 033, a lower connecting rod 034, an intermediate connecting rod 035, and an adjusting rod 036; the lifting frame 031 is located at the top of the suspension device 3 and is hingedly connected with the upper end of the intermediate connecting rod 035 at one end and is hingedly connected with the tractor frame 4 at the other end; the piston rod end of the lifting oil cylinder 032 is hingedly connected with the middle part of the lifting frame 031, and the cylinder end is hingedly connected with the tractor frame 4, so as to control the lifting frame 031 to move up and down through the extension and retraction of the piston rod; the lower end of the intermediate connecting rod 035 is hingedly connected with the lower connecting rod 034, the tail of the lower connecting rod 034 is hingedly connected on the tractor frame 4, and the head is provided with a rod end joint bearing for connecting with the round hole at the lower end of the chopping assembly 300; one end of the limiting rod 033 is hingedly connected on the tractor frame 4, and the other end is hingedly connected on the lower connecting rod 034, so as to limit the lateral swing of the chopping assembly 300 during installation and disassembly; one end of the adjusting rod 036 is hingedly connected with the tractor frame 4, and the other end is hingedly connected with the upper hanging plate 22 on the chopping assembly 300, so as to accurately position the installation angle of the chopping assembly 300 by adjusting the length of the adjusting rod 036.

[0145] The suspension device 3 realizes stable installation and accurate adjustment of the chopping assembly 300 through symmetrical structure and coordination of each component. The lifting frame 031 is located directly above the suspension device 3, one end of which is hinged to the upper end of the middle connecting rod 035, and the other end is hinged to the tractor frame 4. The piston rod end of the lifting oil cylinder 032 is hinged to the middle part of the lifting frame 031, and the cylinder end is hinged to the tractor frame 4. The extension and retraction of the piston rod controls the up and down movement of the lifting frame 031, thereby realizing the height adjustment of the chopping assembly 300. The lower end of the middle connecting rod 035 is hinged to the lower connecting rod 034, and the tail of the lower connecting rod 034 is hinged to the tractor frame 4. The head is provided with a rod end knuckle bearing for connecting with the round hole at the lower end of the chopping assembly 300 to ensure smooth installation. The limiting rod 033 is hinged at one end to the tractor frame 4 and at the other end to the lower connecting rod 034. By limiting the lateral swing of the chopping assembly 300 during installation and disassembly, the stability and safety of operation are improved. The adjusting rod 036 is hinged at one end to the tractor frame 4 and at the other end to the upper hanging plate 22 on the chopping assembly 300. By adjusting the length of the adjusting rod 036, the installation angle of the chopping assembly 300 can be accurately controlled to achieve the best state when the installation frame is docked.

[0146] Referring to FIGS. 33 and 34, the adjusting rod 036 is composed of a right-handed threaded pull rod 361, a right-handed internally threaded connecting rod 362, a handle 363 and a left-handed threaded pull rod 364. The right-handed threaded pull rod 361 and the left-handed threaded pull rod 364 can be screwed with the right-handed internally threaded connecting rod 362. The length of the adjusting rod 036 is adjusted by rotating the handle 363 to finely adjust the installation angle of the chopping assembly 300. The structure of the adjusting rod 036 is realized by the combination of the right-handed threaded pull rod 361, the right-handed internally threaded connecting rod 362, the handle 363 and the left-handed threaded pull rod 364. The right-handed threaded pull rod 361 and the left-handed threaded pull rod 364 can be screwed into the right-handed internally threaded connecting rod 362. The relative position of the two is adjusted by rotating the handle 363. When the handle 363 is rotated clockwise or counterclockwise, the right-handed threaded pull rod 361 and the left-handed threaded pull rod 364 will move closer or farther away from each other, thereby changing the overall length of the adjusting rod 036. This design can finely adjust the installation angle of the chopping assembly 300, so that the chopping assembly 300 can be accurately positioned when installed on the installation frame, ensuring stable installation and efficient operation of the equipment, while simplifying the operation process and making the angle adjustment more flexible and convenient.

[0147] The piston rod end of the lifting cylinder 032 is hinged to the middle part of the lifting frame 031, and the cylinder end is hinged to the tractor frame 4, and the lifting and lowering of the chopping assembly 300 can be achieved by the extension and retraction of the lifting cylinder 032. The structure of the lifting cylinder 032 is hinged to the middle part of the lifting frame 031 through the piston rod end, and is hinged to the tractor frame 4 through the cylinder end, which realizes the lifting and lowering of the chopping assembly 300. When the piston rod of the lifting cylinder 032 extends or retracts, it will change the angle of the lifting frame 031, so that the chopping assembly 300 suspended on the lifting frame 031 moves up and down. This design enables the operator to accurately adjust the height and position of the chopping assembly 300 by controlling the extension and retraction of the lifting cylinder 032, so as to conveniently connect or separate from the installation frame during installation and disassembly.

[0148] The limiting rod 033 of the suspension device 3 is hinged to the tractor frame 4 at one end and to the lower connecting rod 034 at the other end, which is used to limit the left and right lateral swinging of the suspension device 3 after the chopping assembly 300 is hung, to ensure the stability of the installation. The limiting rod 033 of the suspension device 3 is hinged to the tractor frame 4 at one end and to the lower connecting rod 034 at the other end. After the chopping assembly 300 is hung on the suspension device 3, the limiting rod 033 plays a restraining role, limiting the lateral swinging of the suspension device 3 in the left and right directions. This design ensures the stability of the chopping assembly 300 during installation and use, so that it is not easy to swing laterally during driving or other operations, thereby improving the safety and reliability of the equipment.

[0149] Referring to FIG. 34, the upper hanging pin 23 is composed of a pull ring 231 and a pin shaft body 232, the pin shaft body 232 can be inserted into the round hole of the upper hanging plate 22, and the pull ring 231 facilitates the operator to disassemble and assemble the upper hanging pin 23 as a whole. The structure of the upper hanging pin 23 realizes work through the cooperation of the pull ring 231 and the pin shaft body 232, wherein the pin shaft body 232 is designed to be inserted into the round hole of the upper hanging plate 22, and is fixed and disassembled through the pull ring 231. The design of the pull ring 231 enables the operator to easily grasp and pull out the pin shaft body 232, thereby facilitating the overall installation and disassembly of the upper hanging pin 23. This design not only simplifies the operation process, but also makes the connection and separation between the chopping assembly 300 and the suspension device 3 more efficient.

[0150] Referring to FIG. 35, the lower pin 24 includes an adapter plate 241 and a pin body 242, the pin body 242 can be inserted into the round hole on the chopping frame body 21, and the round hole on the adapter plate 241 is fixed on the chopping frame body 21 by bolts. The structure of the lower pin 24 is realized by the cooperation of the adapter plate 241 and the pin body 242, wherein the pin body 242 is designed to be inserted into the round hole on the chopping frame body 21, and the round hole on the adapter plate 241 is fixedly connected with the chopping frame body 21 by bolts, which ensures that the pin body 242 can be firmly fixed on the chopping assembly 300 after being inserted, and the fixation of the adapter plate 241 further enhances the stability of the connection, so that a reliable hinge is formed between the chopping frame body 21 and the lower connecting rod 034.

[0151] The quick disassembly device further includes a magnetic level 5450, which can be installed on the cover plane of the chopping assembly 300 through magnetic attraction, and is used for detecting the vertical state of the chopping assembly 300 to facilitate adjustment during assembly. The magnetic level 5450 is fixed on the cover plane of the chopping assembly 300 through magnetic attraction, and can detect the vertical state of the chopping assembly 300 in real time during installation. When assembling, the operator can judge whether the chopping assembly 300 is in the correct vertical position by observing the reading of the level 450, and if it is found to be inclined, it can be adjusted in time. This design ensures that the chopping assembly 300 can maintain accurate docking angle and position when installed on the installation frame, thereby improving the accuracy and efficiency of assembly and reducing the operation error caused by incorrect position.

[0152] The specific operation steps of the present application will be introduced in detail below in combination with the embodiments.

[0153] As shown in the figure, it is the initial connection state of the installation frame, the chopping assembly 300, the suspension device 3 and the tractor frame 4. At this time, the chopping assembly 300 needs to be disassembled from the C-shaped port of the installation frame to facilitate the user to maintain and repair the chopping assembly 300. In this state, first, the square pin 25 that fixes and locks the main bearing seat 26 of the chopping assembly 300 is disassembled, then the operator does not need to operate the lifting oil cylinder 032 and the adjusting rod 036, and directly drives the tractor to slowly and directly retreat. At this time, the main bearing seat 26 of the chopping assembly 300 slowly separates from the C-shaped port of the installation frame under the indirect action of the suspension device 3. When the chopping assembly 300 is completely disassembled from the installation frame, the telescopic lifting oil cylinder 032 can finally swing the chopping assembly 300 to any position convenient for the operator to maintain, wherein a certain state is shown in the figure.

[0154] As shown in Figure 30, when the maintenance of the chopping assembly 300 is completed and it needs to be restored to the installation frame, at this time the chopping assembly 300, the suspension device 3 and the tractor are integrated and there is no relative movement between them, the operator first drives the tractor to adjust the left and right transverse position of the chopping assembly 300, so that the middle position of the chopping assembly 300 is aligned with the middle position of the installation frame, after the adjustment is completed, the operator controls the extension and retraction of the lifting oil cylinder 032 (for example, in the figure state, the entire main bearing seat 26 is in the upper area of the plane where the hanging seat lower plate 12 is located, at this time the piston rod of the lifting oil cylinder 032 needs to be retracted, so that the chopping assembly 300 falls down), when the lower left edge line (or the lower right edge line) of the main bearing seat 26 is basically coincident with the plane where the hanging seat lower plate 12 is located (the dotted line position), at this time the lifting oil cylinder 032 stops moving, and the adjustment of the adjusting rod 036 to the chopping assembly 300 is started. Since the chopping assembly 300 is adjusted from the figure state, when the lower left edge line of the main bearing seat 26 is basically coincident with the plane where the hanging seat lower plate 12 is located (the dotted line position), it belongs to the forward tilting state, at this time the operator holds the handle 363 and rotates the right-handed internal threaded connecting rod 362 clockwise, at this time the right-handed internal threaded connecting rod 362 is screwed into the right-handed threaded pull rod 361, and the left-handed threaded pull rod 364 is screwed into the right-handed internal threaded connecting rod 362. The entire adjusting rod 036 is shortened, and the chopping assembly 300 rotates clockwise around the axis where the lower insertion pin 24 is located. During the rotation process, the operator observes the state of the magnetic type level meter 5450, when it swings to the vertical state of the chopping assembly 300, at this time the rotation of the right-handed internal threaded connecting rod 362 is stopped, and at this time the up and down position of the chopping assembly 300 has been adjusted. Finally, the operator drives the tractor to drive straight towards the installation frame, and the main bearing seat 26 is from the initial contact with the hanging seat lower plate 12 to the final entry into the C-shaped port, when the end face of the main bearing seat 26 contacts the limiting plate 13, at this time the tractor stops advancing, the operator removes the square pin 25 and the corresponding fastener to connect and lock the chopping assembly 300 and the installation frame, at this time the chopping assembly 300 has been reliably and effectively installed on the installation frame, the operator first pulls out the upper hanging pin 23 to disconnect the upper hanging plate 22 and the adjusting rod 036, then effectively fixes the adjusting rod 036 to prevent it from swinging, and finally disassembles the two lower insertion pins 24 to disconnect the connection between the chopping frame body 21 and the lower connecting rod 034, so that the suspension device 3 and the chopping assembly 300 are completely separated.
