[0026] exist Figure 2 and Figure 3 In the figure, a connecting plate 402 is installed on the right side of the triangular scraper 401, which is used to connect the triangular scraper 401 and the transmission mechanism, so that the triangular scraper 401 can translate back and forth to expand the cleaning range of the push plate body 3.

[0027] exist Figure 2 and Figure 3 In the figure, a storage shell 403 is installed on the top of the push plate body 3 to provide a connection position and installation space for the installation and setting of some components. A first motor 404 is installed on the inner rear wall of the storage shell 403 to drive the screw rod 405 to rotate in forward and reverse directions.

[0028] exist Figure 2 and Figure 3In the figure, a screw rod 405 is installed at the front end of the output shaft of the first motor 404, and a threaded connection is used to drive the bearing plate 406 to move. A bearing block 406 is connected to the inner left wall of the storage shell 403, and is slidably connected to the sliding groove on the inner left wall of the storage shell 403 through a sliding block, thereby restricting its own movement direction, and is threadedly connected to the screw rod 405 through a threaded hole, so that it is affected by the threaded transmission of the screw rod 405.

[0030] exist Figure 3 In the figure, a second motor 408 is installed on the top of the supporting block 406, and a connecting rod is provided on the output shaft for engaging with the mounting groove on the connecting plate 402, so that the rotation of the output shaft of the second motor 408 can drive the connecting plate 402 to rotate, thereby moving the triangular scraper 401 away from the push plate body 3.

[0031] It should be noted that this section is intended to provide a background or context for the implementation methods stated in the claims, and detailed descriptions of known functions and known components are omitted. At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.

[0032] When implementing, follow these steps:

[0033] 1) First, the output shaft of the first motor 404 is started to rotate, driving the screw rod 405 to rotate, and the transmission bearing block 406 is moved by threaded connection;

[0034] 2) Then, under the sliding connection between the sliding groove and the sliding block, the bearing block 406 drives the second motor 408 to move the connecting plate 402 and the triangular scraper 401, so that the triangular scraper 401 moves back and forth on the push plate body 3 to scrape away impurities;

[0035] 3) Finally, after the cleaning is completed, the output shaft of the second motor 408 is started to rotate, driving the connecting rod to move upward in an arc shape, so that the connecting rod pulls the connecting plate 402 to drive the triangular scraper 401 to leave the push plate body 3, thereby releasing the cleaning of the push plate body 3.

[0036] To sum up, the crawler self-propelled rotary tiller can realize the forward and backward translation operation of the triangular scraper 401 through the screw rod 405 and the supporting block 406 under the drive of the first motor 404, and can clean the outer surface of the push plate body 3, which greatly reduces the cost of moving and scraping impurities, thereby facilitating the use of users. At the same time, the connecting plate 402 is connected to the second motor 408 by utilizing the engagement between the connecting rod and the connecting plate 402, which not only facilitates the subsequent movement of the triangular scraper 401, but also facilitates the user to disassemble the triangular scraper 401 and the transmission mechanism, thereby facilitating the maintenance work of the staff.

[0037] Moreover, the setting of the second motor 408 and the connecting rod, combined with the through holes 407 on both sides, allows the triangular scraper 401 to move upward in an arc, thereby keeping the triangular scraper 401 away from the push plate body 3, avoiding interference with the work of the push plate body 3 during the use of the crawler self-propelled rotary tiller, thereby ensuring the working efficiency of the rotary tiller. At the same time, the setting of the through holes 407 on both sides makes it convenient for the staff to directly observe the conditions of the various components inside the storage shell 403, facilitates the staff's maintenance work, further reduces the cost of use, and thus facilitates the use of users, and solves the problems in the comparative documents that the structure is bloated and complicated, the cost of use is increased, and at the same time, the scraper cannot be adjusted, which interferes with the efficiency of the push plate.
