Description

Technical Field

[0001] This invention relates to the field of modern agricultural machinery technology, specifically to a quick-assembly and disassembly device for chopping based on a tractor's three-point suspension. Background Technology

[0002] During the operation of a silage harvester, a series of processes are involved, including harvesting, feeding, chopping, grain crushing, and conveying of silage materials. Chopping is located in the middle of the material flow. The crop conveyed from the front-end device is chopped to a fixed length by the moving and fixed blades in the chopping unit. As one of the main working components, its installation, use, and maintenance require close attention to ensure the reliability and effectiveness of each step. When installing the chopping device onto the silage harvester frame, the space is relatively cramped due to its location between the two front wheels and the cab crossbeam above it, limiting the operating space and increasing the difficulty of installation. Similarly, disassembling the chopping device is also difficult and requires many auxiliary tools. Apart from major malfunctions, after a period of operation, the chopping device often requires a major overhaul and maintenance to ensure that the machine can work more efficiently and for longer periods. To facilitate comprehensive maintenance by users, the chopping device needs to be completely removed from the silage machine frame. Then, the chopping device needs to be inspected, repaired, and parts replaced. After these maintenance and repair work are completed, the chopping device can be reliably and effectively installed in the silage machine frame.

[0003] In the existing technology, when installing a chopping device, overhead cranes, forklifts, and hand-operated hoists are generally used for operation. At least two workers are required to make real-time adjustments during the operation, which is not only time-consuming and labor-intensive, but also poses significant safety hazards. The chopping device suspended by the overhead crane is prone to swaying, which can easily cause serious injury to the workers. Summary of the Invention

[0034] The embodiments of the present invention will be 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 in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0036] This application discloses a quick-assembly and disassembly device for shredding based on a tractor's three-point suspension.

[0037] Reference Figure 1 The quick-assembly and disassembly device for chopping based on a tractor's three-point suspension includes a silage machine frame 1, a chopping device 2, a suspension device 3, and a tractor frame 4. The chopping device 2 is mounted 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 chopping device 2, and the suspension device 3 is connected to the chopping device 2 to adjust the angle of the chopping device 2. The silage machine frame 1 moves on the ground to adjust its position, so that the chopping device 2 and the silage machine frame 1 can be disassembled or assembled at a preset angle and position. The silage harvester frame 1, chopping device 2, suspension device 3, and tractor frame 4 work together to achieve the desired operation. The chopping device 2 is mounted on the silage harvester frame 1, and the suspension device 3 is mounted on the tractor frame 4. In the initial state, the silage harvester frame 1 is connected to the chopping device 2. The suspension device 3 connects to the chopping device 2 through lifting and adjustment functions to precisely control the angle and position of the chopping device 2. During assembly and disassembly, the tractor frame 4 moves slowly on the ground, allowing the chopping device 2 to engage or disengage from the silage harvester frame 1 at a preset angle and position. The adjustment function of the suspension device 3 ensures the stability and accuracy of the operation, thereby simplifying the operation steps, improving the efficiency of assembly and disassembly, reducing reliance on additional auxiliary equipment, improving operational safety, and facilitating regular maintenance and repair of the chopping device 2 by the user.

[0038] The connection between the silage locomotive frame 1 and the chopping device 2 is achieved through two C-shaped openings on the left and right. Above the C-shaped opening is an upper mounting plate 11, and below it is a lower mounting plate 12. A limiting plate 13 is located directly behind the upper and lower plates. The C-shaped openings accommodate the main bearing seat 26 of the chopping device 2. During installation, the main bearing seat 26 is inserted into the C-shaped opening and secured with square pins 25 and corresponding fasteners, thus achieving a stable connection between the chopping device 2 and the silage locomotive frame 1. The stable connection of the chopping device 2 is achieved through the two C-shaped openings on the silage locomotive frame 1. The upper mounting plate 11 is above the C-shaped opening, the lower mounting plate 12 is below it, and the limiting plate 13 is located directly behind the upper and lower plates. During installation, the main bearing seat 26 of the chopping device 2 is precisely inserted into the C-shaped opening. The limiting plate 13 ensures the position of the main bearing seat 26 is fixed, and it is firmly locked using square pins 25 and corresponding fasteners, thus achieving a stable connection between the chopping device 2 and the silage locomotive frame 1.

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

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

[0041] The suspension device 3 has a symmetrical structure and includes a lifting frame 31, a lifting cylinder 32, a limiting 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, with one end hinged to the upper end of the intermediate connecting rod 35 and the other end 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. The lifting frame 31 is moved up and down by the extension and retraction of the piston rod. The lower end of the intermediate connecting rod 35 is connected to the lower connecting rod 34. The lower connecting rod 34 is hinged at the tail to the tractor frame 4, and has a rod end bearing at the head for connecting to the round hole at the lower end of the chopping device 2. One end of the limiting rod 33 is hinged to the tractor frame 4, and the other end is hinged to the lower connecting rod 34 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 mounting plate 22 on the chopping device 2. The installation angle of the chopping device 2 can be precisely positioned by adjusting the length of the adjusting rod 36.

[0042] The suspension device 3, through its symmetrical structure and the coordinated operation of its components, achieves stable installation and precise adjustment of the chopping device 2. The lifting frame 31 is located directly above the suspension device 3, with one end hinged to the upper end of the intermediate connecting rod 35 and the other end 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. The extension and retraction of the piston rod controls the up-and-down movement of the lifting frame 31, thereby achieving height adjustment of the chopping 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. On the locomotive frame 4, the head is equipped with a rod end spherical bearing for connecting with the round hole at the lower end of the chopping device 2, ensuring stability during installation. One end of the limiting rod 33 is hinged to the tractor frame 4, and the other end is hinged to the lower connecting rod 34. By limiting the lateral swing of the chopping device 2 during installation and disassembly, the stability and safety of operation are improved. One end of the adjusting rod 36 is hinged to the tractor frame 4, and the other end is hinged to the upper mounting 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 precisely controlled so that it reaches the optimal state when docking with the silage locomotive frame 1.

[0043] Reference Figure 4 and Figure 5The adjusting rod 36 consists of a right-hand threaded rod 361, a right-hand internal threaded connecting rod 362, a handle 363, and a left-hand threaded rod 364. Both the right-hand threaded rod 361 and the left-hand threaded rod 364 can be screwed into the right-hand internal threaded connecting rod 362. The length of the adjusting rod 36 can be adjusted by rotating the handle 363, so as to make fine adjustments to the installation angle of the chopping device 2. The structure of the adjusting rod 36 achieves fine adjustment through a combination of a right-hand threaded pull rod 361, a right-hand internal threaded connecting rod 362, a handle 363, and a left-hand threaded pull rod 364. Both the right-hand threaded pull rod 361 and the left-hand threaded pull rod 364 can be screwed into the right-hand internal 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-hand threaded pull rod 361 and the left-hand threaded pull rod 364 will move closer or further apart, thereby changing the overall length of the adjusting rod 36. This design allows for fine adjustment of the installation angle of the chopping device 2, enabling precise positioning of the chopping device 2 when installed on the silage locomotive frame 1, ensuring stable installation and efficient operation of the equipment. It also simplifies the operation process, making 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 chopping device 2 can swing up and down by extending and retracting the lifting cylinder 32. The structure of the lifting cylinder 32 enables the chopping device 2 to swing up and down through the hinge between the piston rod end and the middle of the lifting frame 31, and the hinge between the cylinder end and the tractor frame 4. When the piston rod of the lifting cylinder 32 extends or retracts, it will cause the angle of the lifting frame 31 to change, thereby causing the chopping device 2 suspended on the lifting frame 31 to move up and down. This design allows the operator to precisely adjust the height and position of the chopping device 2 by controlling the extension and retraction of the lifting cylinder 32, so as to easily connect or disconnect the silage harvester frame 1 during installation and disassembly.

[0045] One end of the limiting rod 33 of the suspension device 3 is hinged to the tractor frame 4, and the other end is hinged to the lower connecting rod 34. This limit rod restricts the lateral sway of the suspension device 3 after the shredder 2 is attached, ensuring installation stability. The limiting rod 33, with one end hinged to the tractor frame 4 and the other end hinged to the lower connecting rod 34, acts as a constraint after the shredder 2 is attached to the suspension device 3, limiting the lateral sway of the suspension device 3. This design ensures the stability of the shredder 2 during installation and use, making it less prone to lateral swaying during driving or other operations, thereby improving the safety and reliability of the equipment.

[0046] Reference Figure 6The upper hanging pin 23 consists of a pull ring 231 and a pin body 232. The pin body 232 can be inserted into the round hole of the upper hanging plate 22, and the pull ring 231 facilitates the operator's overall assembly and disassembly of the upper hanging pin 23. The structure of the upper hanging 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 hanging plate 22 and is fixed and disassembled by the pull ring 231. The design of the pull ring 231 allows the operator to easily grasp and pull out the pin body 232, thereby facilitating the overall assembly 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 device 2 and the suspension device 3 faster.

[0047] Reference Figure 7 The lower pin 24 includes an ear plate 241 and a pin body 242. The pin body 242 can be inserted into a round hole on the shredding frame body 21. The round hole on the ear plate 241 is fixed to the shredding frame body 21 by bolts. The structure of the lower pin 24 achieves its operation through the cooperation of the ear plate 241 and the pin body 242. The pin body 242 is designed to be inserted into the round hole on the shredding frame body 21. The round hole on the ear plate 241 is fixedly connected to the shredding frame body 21 by bolts. This design ensures that the pin body 242 can be firmly fixed to the shredding device 2 after insertion. The fixing 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 tractor-based three-point suspension quick-assembly and disassembly device for chopping also includes a magnetic level 5, which can be magnetically attached to the surface of the shredder 2's housing to detect the verticality of the chopping device 2 for adjustment during assembly. The magnetic level 5 is fixed to the surface of the shredder 2's housing by magnetic attraction, enabling real-time detection of the chopping device 2's verticality during installation. During assembly, the operator can observe the level reading to determine if the chopping device 2 is in the correct vertical position. If any deviation is detected, timely adjustment can be made. This design ensures that the chopping device 2 maintains a precise docking angle and position when installed onto the silage harvester frame 1, thereby improving assembly accuracy and efficiency and reducing operational errors caused by misalignment.

[0049] The specific operation steps of this invention patent are described in detail below with reference to the embodiments.

[0050] like Figure 2The diagram shows the initial connection state of the silage locomotive frame 1, the chopping device 2, the suspension device 3, and the tractor frame 4. At this point, the chopping device 2 needs to be disassembled from the C-shaped opening of the silage locomotive frame 1 for easy maintenance. In this state, first remove the square pin 25 securing the main bearing seat 26 in the chopping device 2. Then, without operating the lifting cylinder 32 or the adjusting rod 36, the operator can drive the tractor straight and slowly backward. Under the indirect action of the suspension device 3, the main bearing seat 26 of the chopping device 2 slowly detaches from the C-shaped opening of the silage locomotive frame 1. After the chopping device 2 is completely separated from the silage locomotive frame 1, the chopping device 2 can be swung to any convenient position for maintenance by the operator using the telescopic lifting cylinder 32. One possible state is as follows... Figure 8 As shown.

[0051] like Figure 9 As shown, when the chopping device 2 needs to be reinstalled on the silage locomotive frame 1 after maintenance, the chopping device 2, suspension device 3, and 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 chopping device 2 so that the middle position of the chopping device 2 is aligned with the middle position of the silage locomotive frame 1. After adjustment, the operator controls the extension and retraction of the lifting cylinder 32 (for example, in...). Figure 8 In the initial state, the entire main bearing housing 26 is located above the plane of the lower plate 12 of the mounting base. At this time, it is necessary to control the piston rod of the lifting cylinder 32 to retract, so that the chopping device 2 descends. When the lower left (or lower right) edge of the main bearing housing 26 is basically aligned with the plane of the lower plate 12 of the mounting base (dashed line position), the lifting cylinder 32 stops operating, and the adjusting rod 36 begins to finely adjust the chopping device 2. Figure 8When adjusting the chopping device 2, it is in a forward-tilted state when the lower left edge of its main bearing seat 2 is basically aligned with the plane (dashed line position) of the lower plate 12 of the mounting base. At this time, the operator holds the handle 363 and rotates the right-hand internal thread connecting rod 362 clockwise. The right-hand internal thread connecting rod 362 is screwed into the right-hand threaded pull rod 361, while the left-hand threaded pull rod 364 is screwed into the right-hand internal thread connecting rod 362. The entire adjusting rod 36 is shortened, and the chopping device 2 rotates clockwise around the axis of the lower pin 24. During the rotation, the operator should observe the state of the magnetic level 5. When the chopping device 2 swings to a vertical position, stop rotating the right-hand internal thread connecting rod 362. The vertical position of the chopping device 2 has now been adjusted. Finally, the operator drives the tractor straight toward the silage locomotive frame 1. The main bearing seat 26 initially contacts the lower plate 12 of the mounting bracket and eventually enters the C-shaped opening. When the end face of the main bearing seat 26 contacts the limit plate 13, the tractor stops moving forward. The operator takes out the square pin 25 and the corresponding fasteners to connect and lock the chopping device 2 to the silage locomotive frame 1. At this time, the chopping device 2 is reliably and effectively installed on the silage locomotive frame 1. The operator first pulls out the upper mounting pin 23 to disconnect the upper mounting plate 22 from the adjusting rod 36, then effectively fixes the adjusting rod 36 to prevent it from swinging freely. Finally, the two lower pins 24 are removed to disconnect the connection between the chopping frame body 21 and the lower connecting rod 34. In this way, the suspension device 3 is completely separated from the chopping device 2.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
