[0002] The working process of the silage harvester involves a series of processes such as harvesting, feeding, chopping, grain crushing and throwing of silage materials. Chopping is located in the middle link of the material flow. The crops transported from the front-end device are chopped at a fixed length at the shearing edge of the moving and fixed knives in the chopping component. As one of the main working parts, its installation, use, and maintenance require extra attention to ensure the reliability and effectiveness of each link. When the chopping device is installed on the silage machine frame, since the chopping device is basically arranged between the two front wheels and there is a cab crossbeam above, the space position is relatively cramped and the operating space is limited, which increases the difficulty of installing the chopping device and the silage machine frame. Similarly, it is also difficult to disassemble the chopping device, and a lot of auxiliary tooling needs to be set up. Except for major failures, the shredder device often needs a major overhaul and maintenance after working for a period of time to ensure that the machine can work more efficiently and sustainably. In order to facilitate users to perform comprehensive maintenance on it, the shredder device needs to be completely separated from the silage machine frame, and then the shredder device needs to be inspected, repaired, and parts replaced.

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0035] The following is combined with Figure 1-9 This application is described in further detail.

[0036] The embodiment of the present application discloses a quick-disassembly and shredding device based on a three-point suspension of a tractor.

[0037] Reference Figure 1 The shredder quick disassembly and assembly device based on the tractor three-point suspension comprises a silage machine frame 1, a shredder device 2, a suspension device 3 and a tractor frame 4; the shredder device 2 is assembled on the silage machine frame 1, and the suspension device 3 is mounted on the tractor frame 4. In the initial state, the silage machine frame 1 is connected to the shredder device 2, and the suspension device 3 is connected to the shredder device 2 for adjusting the angle of the shredder device 2. The silage machine frame 1 moves on the ground to adjust the position, so that the shredder device 2 and the silage machine frame 1 can be disassembled or assembled at a preset angle and position. The operation is achieved through the cooperation of the silage machine frame 1, the shredder device 2, the suspension device 3 and the tractor frame 4, wherein the shredder device 2 is assembled on the silage machine frame 1, and the suspension device 3 is installed on the tractor frame 4. In the initial state, the silage machine frame 1 is connected to the shredder device 2, and the suspension device 3 is connected to the shredder device 2 through the lifting and adjustment functions, so as to accurately control the angle and position of the shredder device 2; during the disassembly and assembly process, the tractor frame 4 moves slowly on the ground, so that the shredder device 2 and the silage machine frame 1 are docked or separated at a preset angle and position, and the adjustment function of the suspension device 3 ensures the stability and accuracy of the operation, thereby simplifying the operating steps, improving the disassembly and assembly efficiency, reducing the dependence on additional auxiliary equipment, improving the operational safety, and facilitating the user to perform regular maintenance and overhaul of the shredder device 2.

[0038] The connection between the silage locomotive frame 1 and the shredder 2 is through two C-shaped openings on the left and right, with a hook seat upper plate 11 above the C-shaped opening, a hook seat lower plate 12 below the C-shaped opening, and a limit plate 13 directly behind the upper and lower plates; the C-shaped opening is used to accommodate the main bearing seat 26 of the shredder 2. During the installation process, the main bearing seat 26 is inserted into the C-shaped opening and fixed by a square pin 25 and corresponding fasteners, thereby realizing a stable connection between the shredder 2 and the silage locomotive frame 1. The stable connection of the shredder 2 is realized through the two C-shaped openings on the silage locomotive frame 1, wherein a hook seat upper plate 11 is provided above the C-shaped opening, a hook seat lower plate 12 is provided below the C-shaped opening, and a limit plate 13 is provided directly behind the upper and lower plates. During installation, the main bearing seat 26 of the shredder 2 is accurately inserted into the C-shaped opening, and the limit plate 13 ensures that the position of the main bearing seat 26 is fixed, and the square pin 25 and corresponding fasteners are used to firmly lock it, thereby realizing a stable connection between the shredder 2 and the silage locomotive frame 1.

[0039] Reference Figure 2 and Figure 3 The shredder device 2 includes a shredder frame body 21, an upper mounting plate 22, an upper mounting pin 23, a lower latch pin 24, a square pin 25 and a main bearing seat 26; the upper mounting plate 22 is located at the front upper part of the shredder device 2 and is fixedly connected to the shredder frame body 21 by welding or bolting; the circular hole of the upper mounting plate 22 is used to accommodate the upper mounting pin 23, and the pin shaft body 232 of the upper mounting pin 23 is inserted into the circular hole and fixed by a pull ring 231 to realize the detachable connection between the upper mounting plate 22 and the suspension device 3; a lower latch pin 24 is provided at the front lower part of the shredder device 2, and the shredder frame body 21 is hinged to the lower connecting rod 34 by an ear plate 241 and a latch pin body 242; the main bearing seat 26 is fixed to the rear part of the shredder frame body 21, and is inserted into the C-shaped opening of the silage machine frame 1 and fastened using a square pin 25 and bolts.

[0040] The shredder 2 is stably connected to the silage machine frame 1 and detachably connected to the suspension device 3 through the cooperation of multiple components. The upper mounting plate 22 of the shredder 2 is located at the upper front portion and is firmly connected to the shredder frame body 21 by welding or bolting. The circular hole on the upper mounting plate 22 accommodates the upper mounting pin 23. The pin shaft body 232 is inserted into the circular hole and fixed by the pull ring 231, ensuring that the shredder 2 and the suspension device 3 can be quickly disassembled and assembled; the lower latch 24 at the lower front portion of the shredder 2 hinges the shredder frame body 21 with the lower connecting rod 34 through the ear plate 241 and the latch body 242, ensuring that the device remains stable during operation; the main bearing seat 26 is located at the rear of the shredder 2, and is inserted into the C-shaped opening of the silage machine frame 1 and fastened with a square pin 25 and bolts. This design of the main bearing seat 26 ensures that the shredder 2 can be firmly fixed to the silage machine frame 1 and can be quickly disassembled and assembled.

[0041] The suspension device 3 has a bilaterally symmetrical structure, including a lifting frame 31, a lifting cylinder 32, a limit rod 33, a lower connecting rod 34, an intermediate connecting rod 35 and an adjusting rod 36; the lifting frame 31 is located directly above the suspension device 3, one end of which is hinged to the upper end of the intermediate connecting rod 35, and the other end is hinged to the tractor frame 4; the piston rod end of the lifting cylinder 32 is hinged to the middle of the lifting frame 31, and the cylinder end is hinged to the tractor frame 4, and the lifting frame 31 is controlled to move up and down by the telescopic action of the piston rod; the lower end of the intermediate connecting rod 35 is hinged to the lower connecting rod 34 The tail of the lower connecting rod 34 is hinged on the tractor frame 4, and the head has a rod end joint bearing for connecting with the round hole at the lower end of the chopping device 2; one end of the limit rod 33 is hinged on the tractor frame 4, and the other end is hinged on the lower connecting rod 34, which is used to limit the lateral swing of the chopping device 2 during installation and disassembly; one end of the adjusting rod 36 is hinged to the tractor frame 4, and the other end is hinged to the upper hanging plate 22 on the chopping device 2. The installation angle of the chopping device 2 can be accurately positioned by adjusting the length of the adjusting rod 36.

[0042] The suspension device 3 realizes stable installation and precise adjustment of the shredder device 2 through the bilaterally symmetrical structure and the coordinated cooperation of various components. The lifting frame 31 is located directly above the suspension device 3, one end of which is hinged to the upper end of the intermediate connecting rod 35, and the other end is hinged to the tractor frame 4. The piston rod end of the lifting cylinder 32 is hinged to the middle part of the lifting frame 31, and the cylinder end is hinged to the tractor frame 4. The telescopic action of the piston rod controls the up and down movement of the lifting frame 31, thereby realizing the height adjustment of the shredder device 2; the lower end of the intermediate connecting rod 35 is hinged to the lower connecting rod 34, and the tail of the lower connecting rod 34 is hinged to the tractor frame 4. On the locomotive frame 4, the head is provided with a rod end joint bearing, which is used to connect with the circular hole at the lower end of the chopping device 2 to ensure stability during the installation process; one end of the limit rod 33 is hinged on the tractor frame 4, and the other end is hinged on the lower connecting rod 34, which improves the stability and safety of the operation by limiting the lateral swing of the chopping device 2 during installation and disassembly; one end of the adjusting rod 36 is hinged to the tractor frame 4, and the other end is hinged to the upper hanging plate 22 on the chopping device 2. By adjusting the length of the adjusting rod 36, the installation angle of the chopping device 2 can be accurately controlled so that it reaches the optimal state when docking with the silage machine frame 1.

[0043] Reference Figure 4 and Figure 5The adjusting rod 36 is composed of a right-handed threaded rod 361, a right-handed internally threaded connecting rod 362, a handle 363 and a left-handed threaded rod 364. Both the right-handed threaded rod 361 and the left-handed threaded rod 364 can be screwed together with the right-handed internally threaded connecting rod 362. The length of the adjusting rod 36 can be adjusted by rotating the handle 363 so as to finely adjust the installation angle of the shredder 2. The structure of the adjustment rod 36 achieves fine adjustment through the combination of a right-handed threaded rod 361, a right-handed internally threaded connecting rod 362, a handle 363 and a left-handed threaded rod 364, wherein the right-handed threaded rod 361 and the left-handed threaded rod 364 can both be screwed into the right-handed internally threaded connecting rod 362, and the relative positions of the two are adjusted by rotating the handle 363. When the handle 363 is rotated clockwise or counterclockwise, the right-handed threaded rod 361 and the left-handed threaded rod 364 will move closer to or farther away from each other, thereby changing the overall length of the adjustment rod 36. This design can finely adjust the installation angle of the shredder 2, so that the shredder 2 can be accurately positioned when installed on the silage machine frame 1, ensuring the stable installation and efficient operation of the equipment, while also simplifying the operation process, making the angle adjustment more flexible and convenient.

[0044] The piston rod end of the lifting cylinder 32 is hinged to the middle of the lifting frame 31, and the cylinder end is hinged to the tractor frame 4. The up and down swing of the chopping device 2 can be realized by the extension and contraction of the lifting cylinder 32. The structure of the lifting cylinder 32 realizes the up and down swing of the chopping device 2 by the hinge connection of the piston rod end to the middle of the lifting frame 31 and the hinge connection of the cylinder end to the tractor frame 4. When the piston rod of the lifting cylinder 32 is extended or retracted, the angle of the lifting frame 31 will be driven to change, so that the chopping device 2 suspended on the lifting frame 31 moves up and down. This design enables the operator to accurately adjust the height and position of the chopping device 2 by controlling the extension and contraction of the lifting cylinder 32, so as to conveniently dock or detach from the silage machine frame 1 during installation and disassembly.

[0045] One end of the limit rod 33 of the suspension device 3 is hinged on the tractor frame 4, and the other end is hinged on the lower connecting rod 34, which is used to limit the left and right lateral swing of the suspension device 3 after the shredder device 2 is hung, so as to ensure the stability of the installation. The limit rod 33 of the suspension device 3 is hinged on the tractor frame 4 at one end, and is hinged on the lower connecting rod 34 at the other end. After the shredder device 2 is hung on the suspension device 3, the limit rod 33 plays a restraining role, limiting the lateral swing of the suspension device 3 in the left and right directions. Such a design ensures the stability of the shredder device 2 during installation and use, and makes it less likely to sway laterally during driving or other operations, thereby improving the safety and reliability of the equipment.

[0046] Reference Figure 6The upper hook pin 23 is composed of a pull ring 231 and a pin body 232. The pin body 232 can be inserted into the round hole of the upper hook plate 22. The pull ring 231 facilitates the operator to disassemble and assemble the upper hook pin 23 as a whole. The structure of the upper hook pin 23 works through the cooperation of the pull ring 231 and the pin body 232. The pin body 232 is designed to be inserted into the round hole of the upper hook plate 22 and is fixed and disassembled by the pull ring 231. The design of the pull ring 231 enables the operator to easily grab and pull out the pin body 232, thereby facilitating the overall installation and disassembly of the upper hook pin 23. This design not only simplifies the operation process, but also makes the connection and separation between the shredder 2 and the suspension device 3 faster.

[0047] Reference Figure 7 The lower latch 24 includes an ear plate 241 and a latch body 242. The latch body 242 can be inserted into the circular hole on the shredding frame body 21. The circular hole on the ear plate 241 is fixed to the shredding frame body 21 by bolts. The structure of the lower latch 24 works through the cooperation of the ear plate 241 and the latch body 242. The latch body 242 is designed to be inserted into the circular hole on the shredding frame body 21. The circular hole on the ear plate 241 is fixedly connected to the shredding frame body 21 by bolts. Such a design ensures that the latch body 242 can be firmly fixed to the shredding device 2 after insertion. The fixation of the ear plate 241 further enhances the stability of the connection, thereby forming a reliable hinge between the shredding frame body 21 and the lower connecting rod 34.

[0048] The shredder quick disassembly and assembly device based on the three-point suspension of the tractor also includes a magnetic level 5, which can be installed on the hood plane of the shredder 2 through magnetic attraction, and is used to detect the vertical state of the shredder 2 so as to make adjustments during assembly. The magnetic level 5 is fixed on the hood plane of the shredder 2 through magnetic attraction, and can detect the vertical state of the shredder 2 in real time during the installation process. When assembling, the operator can judge whether the shredder 2 is in the correct vertical position by observing the reading of the level. If deviation is found, it can be adjusted in time. This design ensures that the shredder 2 can maintain a precise docking angle and position when it is installed on the silage machine frame 1, thereby improving the accuracy and efficiency of assembly and reducing operational errors caused by incorrect position.

[0049] The specific operation steps of the present invention are fully described below in conjunction with the embodiments.

[0050] like Figure 2The figure shows the initial connection state of the silage machine frame 1, the chopping device 2, the suspension device 3, and the tractor frame 4. At this time, the chopping device 2 needs to be disassembled from the C-shaped opening of the silage machine frame 1 to facilitate the user to inspect and maintain the chopping device 2. In this state, first remove the square pin 25 that fixes and locks the main bearing seat 26 in the chopping device 2. Then the operator does not need to perform any operation on the lifting cylinder 32 and the adjusting rod 36, and directly drives the tractor straight and slowly back. At this time, the main bearing seat 26 of the chopping device 2 is slowly separated from the C-shaped opening of the silage machine frame 1 under the indirect action of the suspension device 3. When the chopping device 2 is completely separated from the silage machine frame 1, the chopping device 2 can be swung to any position that is convenient for the operator to inspect it by telescoping the lifting cylinder 32. A certain state such as Figure 8 shown.

[0051] like Fig. 9 As shown in the figure, when the shredder device 2 needs to be restored and installed on the silage machine frame 1 after being repaired, the shredder device 2, 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 lateral positions of the shredder device 2 so that the middle position of the shredder device 2 is aligned with the middle position of the silage machine frame 1. After the adjustment is completed, the operator controls the extension and contraction of the lifting cylinder 32 (for example, in Figure 8 When the main bearing seat 26 is in the upper area of ​​the plane where the lower plate 12 of the mounting seat is located, the piston rod of the lifting cylinder 32 needs to be retracted to make the shredder 2 fall downward. When the lower left edge line (or lower right edge line) of the main bearing seat 2 is adjusted to basically coincide with the plane where the lower plate 12 of the mounting seat is located (the dotted line position), the lifting cylinder 32 stops moving and starts to adjust the adjusting rod 36 to finely adjust the shredder 2. Figure 8When the state of the shredder 2 is adjusted, the shredder 2 is in a forward tilted state when the lower left edge line of the main bearing seat 2 is basically coincident with the plane (dashed line position) where the lower plate 12 of the mounting seat is located. 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 at the same time, the left-handed threaded pull rod 364 is screwed into the right-handed internal threaded connecting rod 362. The entire adjusting rod 36 is shortened, and the shredder 2 rotates clockwise around the axis where the lower latch pin 24 is located. During the rotation, the operator pays attention to the state of the magnetic level 5. When the shredder 2 is swung to a vertical state, the right-handed internal threaded connecting rod 362 is stopped from rotating. At this point, the upper and lower positions of the shredder 2 have been adjusted. Finally, the operator drives the tractor straight toward the silage machine frame 1, and the main bearing seat 26 initially contacts the lower plate 12 of the hitch seat and finally enters the C-shaped opening. When the end face of the main bearing seat 26 contacts the limit plate 13, the tractor stops moving, and the operator takes out the square pin 25 and the corresponding fasteners to connect and lock the shredder 2 and the silage machine frame 1. At this time, the shredder 2 has been reliably and effectively installed on the silage machine frame 1. The operator first pulls out the upper hitch pin 23 to release the connection between the upper hitch plate 22 and the adjusting rod 36, and then effectively fixes the adjusting rod 36 to prevent it from swinging at will, and finally removes the two lower pins 24 to release the connection between the shredder frame body 21 and the lower connecting rod 34, so that the suspension device 3 is completely separated from the shredder 2.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
