Description

Technical Field

[0001] The invention belongs to the technical field of harvester crawlers, and in particular relates to a crawler for a green onion harvester. Background Art

[0002] With the booming green onion cultivation industry, mechanized harvesting has become key to improving efficiency and reducing costs, and green onion harvesters are becoming increasingly important. The performance of crawler tracks, the core moving component of a harvester, directly impacts the success of harvesting operations. Existing crawler tracks for green onion harvesters have exposed numerous issues in practical use, particularly the lack of mud removal, which has caused significant challenges in green onion harvesting.

[0003] Most of the existing crawler tracks for green onion harvesters only have basic walking functions, and the design focus is mainly focused on ensuring the stable movement of the harvester, but ignores the problem of green onions with mud during the harvesting process. When harvesting green onions, a large amount of soil will adhere to the roots and stems of the green onions. Since the crawler does not have the mud removal function, the mud will continue to accumulate on the crawler as the harvester moves. On the one hand, the increased load on the crawler causes the energy consumption of the harvester to increase significantly, which not only increases the operating cost, but may also cause excessive loss of the harvester's power system and shorten the service life of the equipment. On the other hand, the accumulated mud will affect the adhesion between the crawler and the ground. On wet or soft land, slipping is very likely to occur, reducing the walking stability of the harvester. In severe cases, the harvester may even sink into the mud and be unable to operate normally, greatly affecting the harvesting efficiency. Therefore, we propose a green onion harvester crawler to solve the problem. Summary of the Invention

[0020] This specific embodiment is a crawler for a green onion harvester, and its structural diagram is shown in FIG. Figure 1-7 As shown, the crawler for the green onion harvester includes a crawler body 1.

[0021] In this embodiment, if Figure 2 and Figure 3 As shown, a buffer assembly 2 is installed on the inner surface of the crawler body 1, which can play a certain buffering effect during the walking process to reduce the degree of damage to the crawler body 1.

[0022] Specifically, the buffer assembly 2 includes a movable rod 21, the lower end of the movable rod 21 is connected to the disassembly and assembly assembly 3, the upper end of the movable rod 21 is movably connected to the column rod 22 through the first mounting short shaft 23, the outer wall fixed sleeve of the column rod 22 near the lower end is provided with a circular block 25, and the outer wall sliding sleeve of the upper end of the column rod 22 is provided with a movable sleeve 27, a second buffer spring 26 is connected between the movable sleeve 27 and the circular block 25, the second buffer spring 26 is sleeved on the outside of the column rod 22, one end of the second buffer spring 26 is fixedly installed with the circular block 25, and the other end of the second buffer spring 26 is fixedly installed with the movable sleeve 27, the upper end of the movable sleeve 27 is movably connected to a movable connecting rod 28 through a pin, the upper end of the movable connecting rod 28 is movably sleeved with a plug column 29, the outer wall of the plug column 29 is movably sleeved with an auxiliary block 210, and the top of the auxiliary block 210 is fixedly installed with the inner surface of the crawler body 1.

[0023] In this embodiment, it should be noted that there is a distance set between the lower end of the cylindrical rod 22 and the upper end of the movable rod 21, and a first buffer spring 24 is provided between the lower end of the cylindrical rod 22 and the upper end of the movable rod 21. The first buffer spring 24 is sleeved on the outer wall of the first mounting short shaft 23, and one end of the first buffer spring 24 is fixedly installed on the side of the upper end of the movable rod 21, and the first buffer spring 24 is fixedly installed on the side of the lower end of the cylindrical rod 22 away from the end of the movable rod 21. Here, by arranging the first buffer spring 24 at the connection between the movable rod 21 and the cylindrical rod 22, the connection can have a buffering effect under stress, which has a certain protective effect on the connection part.

[0024] In this embodiment, if Figure 4 and Figure 5 As shown, a disassembly assembly 3 is installed on the inner surface of the crawler body 1, and the disassembly assembly 3 is used for installation and disassembly between the buffer assembly 2 and the crawler body 1.

[0025] Specifically, the disassembly and assembly component 3 includes a fixed column 31, which is movably connected to the lower end of the movable rod 21 through a pin. The fixed column 31 is clamped with the arc groove 5 opened on the inner surface of the crawler body 1. The end face of the fixed column 31 has a cylindrical clamping groove 6 and an auxiliary rectangular groove 7. The auxiliary rectangular groove 7 is communicated with the cylindrical clamping groove 6. The cylindrical clamping groove 6 is slidably provided with a clamping column 32. The end of the clamping column 32 movably passes through the cylindrical barrel 8 opened on the inner wall of the arc groove 5, and is slidably provided with the inner wall of the cylindrical through-opening 8. The end of the clamping column 32 away from the cylindrical through-opening 8 is fixedly installed with a first connecting spring 33, and the end of the first connecting spring 33 is fixedly installed with the inner wall of the cylindrical clamping groove 6.

[0026] In this embodiment, it should be noted that a limiting block 34 is fixedly installed at the end of the clamping column 32, and the limiting block 34 is clamped with the limiting rectangular groove 9 opened on the inner wall of the cylindrical opening 8. A sealing plug 35 is provided on the surface contact of the limiting block 34, and the sealing plug 35 is clamped with the inner wall of the cylindrical opening 8. By setting the limiting block 34, especially clamping the limiting block with the limiting rectangular groove 9, the clamping stability of the clamping column 32 can be enhanced, and the clamping column 32 can be prevented from moving back, resulting in loose installation. Here, the installed sealing plug 35 can play a role of sealing protection.

[0027] In this embodiment, if Figure 6 As shown, the buffer assembly 2 is connected to the mud removal assembly 4 .

[0028] Specifically, the mud removal assembly 4 includes a mounting rod 41, which is movably connected to the movable rod 21 through a second mounting short shaft 42. The surface of the mounting rod 61 has a rectangular opening, and a mounting column 44 is fixedly installed on the inner wall of the rectangular opening. The outer wall of the mounting column 44 is slidably sleeved with a plurality of rectangular blocks 45, and the ends of the rectangular blocks 45 are fixedly installed with mud removal scraper hooks 46. Every two adjacent rectangular blocks 45 are connected by a third connecting spring 47, and the third connecting spring 47 is sleeved on the outer wall of the mounting column 44. The mud removal scraper hooks 46 located at both ends are fixedly installed on the inner wall of the rectangular opening through a fourth connecting spring 48, and the fourth connecting spring 48 is sleeved on the outer wall of the mounting column 44.

[0029] In this embodiment, it should be noted that a second connecting spring 43 is sleeved on the outer wall of the second mounting short shaft 42, one end of the second connecting spring 43 is fixedly mounted to the mounting rod 41, and the other end of the second connecting spring 43 is fixedly mounted to the movable rod 21. By installing the second connecting spring 43 between the second mounting short shaft 42 and the mounting rod 61, the reciprocating swinging phenomenon of the mounting rod 61 can be strengthened, which can promote mud removal work.

[0030] In this embodiment, it should be noted that the height of the rectangular block 45 is less than the inner wall height of the rectangular opening on the surface of the mounting rod 41. This arrangement allows the rectangular block 45 to swing under force, which can be used to promote the mud removal work of the mud removal scraper hook.

[0031] When the crawler of the green onion harvester of the present technical solution is used, an external force of vibration may be generated during the walking process of the crawler body 1. At this time, the auxiliary block 210 will be subjected to the vibration force. At this time, the movable connecting rod 28 will be movable and changeable, and the movable sleeve 27 may be moved along the outer wall of the cylindrical rod 22 and squeeze the second buffer spring 26, so that the second buffer spring 26 may play a buffering role, which can protect the crawler body 1. At the same time, the movable rod 21 will also be movable and changeable, prompting the first buffer spring 24 to play a buffering role, and play a buffering and protective role for the connection between the movable rod 21 and the cylindrical rod 22, so that the buffer assembly 2 can have a better buffering effect. During the movable change process of the cylindrical rod 22, the movable rod 21 will also be prompted to move and change. During the movable change process of the movable rod 21, the second mounting short shaft 42 can drive the mounting rod 41 to have a movable change, especially the second connecting spring 26 arranged between the movable rod 21 and the mounting rod 41. The spring 43 can promote the reciprocating change of the mounting rod 41, and the reciprocating change can promote the demudification scraping hook 46 to also have a reciprocating change, so as to better play the effect of demudification. In the demudification process, the demudification scraping hook 46 will generate an extrusion force with the soil. At this time, under the action of the third connecting spring 47 and the fourth connecting spring 48, the demudification scraping hook 46 can be promoted to have a reciprocating movement trend, and the demudification scraping hook 46 can also be made to have vibration to avoid affecting the demudification work of the demudification scraping hook 46. Finally, when the buffer assembly is needed 2 and mud removal assembly 4, at this time, it is only necessary to open the sealing plug 35, then use the tool to pull the limit block 34 outward, and rotate the limit block 34 at a 90-degree trend, and then push the limit block 34 inward until the limit block 34 and the card column 32 are all entered into the cylindrical card groove 6 in the fixed column 31, and then move the fixed column 31 upward to disengage the fixed column 31 from the arc groove 5, and then pull outward to the buffer assembly 2 to disengage the plug column 29 from the auxiliary block 210, and then the disassembly work can be completed.

[0032] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
