Detailed implementation manner

[0017] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] Refer to Figure 1 , Figure 2 , the present utility model provides a crawler cleaning device for a crawler belt conveyor, mainly including a bottom shell 1, an upper cover 3 and a plurality of mud removal plates 4. The bottom shell 1 serves as the basic support structure of the entire device, on which a push rod 2 is provided for holding during crawler cleaning. An expansion mechanism is arranged inside the bottom shell 1, and the mud removal plates 4 are arranged on the expansion mechanism, and an equal distance is maintained between two adjacent mud removal plates 4. This mechanism can adjust the distance between the mud removal plates 4 as needed to adapt to crawler grooves with different distances. The upper cover 3 is arranged above the bottom shell 1 to completely cover the expansion mechanism to protect it from being eroded and damaged by the external environment.

[0019] A locking mechanism 6 is arranged on the expansion mechanism. The function of this mechanism is to firmly fix the mud removal plates 4 on the expansion mechanism to prevent loosening or falling off during the cleaning process. At the same time, an unlocking push plate 5 that cooperates with the locking mechanism 6 is also arranged on the bottom shell 1, and the locking mechanism 6 can be conveniently unlocked by pushing the unlocking push plate 5.

[0020] In specific implementation, the expansion mechanism includes a guiding rod 102, a driving rod 101 and a plurality of connecting rods 107. The guiding rod 102 and the driving rod 101 are arranged in parallel inside the bottom shell 1 to provide stable support and guidance for the entire expansion mechanism. A positioning seat 103, two driving seats 104 and a plurality of sliding seats 105 are also installed inside the bottom shell 1. The locking mechanism 6 and the mud removal plates 4 are arranged on these components, and the mud removal plates 4 are inserted therein.

[0021] The positioning seat 103 is fixedly installed inside the bottom shell 1, providing a fixed reference point for the entire telescopic mechanism. The driving seat 104 and the sliding seat 105 are symmetrically arranged on both sides of the positioning seat 103. The driving seat 104 is slidably connected to the guide rod 102. Threaded sections 108 are provided on the driving rods 101 on both sides of the positioning seat 103, and the driving seat 104 is in threaded engagement with the threaded sections 108. The sliding seat 105 is slidably connected to both the guide rod 102 and the driving rod 101 and can freely slide on the guide rod 102 and the driving rod 101. A number of connecting rods 107 are articulated end to end and their middle parts are rotatably connected to the locking mechanism 6. A driving wheel 106 is installed on the outside of the bottom shell 1, and the driving wheel 106 is coaxially connected to the driving rod 101. Rotating the driving wheel 106 causes the driving rod 101 to rotate, which can drive the driving seat 104 to slide along the guide rod 102. Through the connecting rod 107, the sliding seat 105 and the driving seat 104 are expanded or contracted centered on the positioning seat 103, thereby adjusting the spacing of the mud removal plates 4 and keeping the spacing equal under the action of the connecting rod 107. This equal-spacing setting method can ensure that during the cleaning process, multiple crawler grooves are cleaned simultaneously to improve efficiency. To prevent the connecting rod 107 from being straightened and parallel to the driving rod 101 during the spacing adjustment and resulting in non-return, a limiting post 109 is provided on the sliding seat 105. The limiting post 109 is arranged on both sides of the connecting rod 107 and is used to limit the swinging range of the connecting rod 107.

[0022] Referring to Figure 3 , the locking mechanism 6 includes a rotating sleeve 601, a locking pin 602, and a tension spring 603. The rotating sleeve 601 is rotatably connected to the connecting rod 107. Both the locking pin 602 and the tension spring 603 are arranged inside the rotating sleeve 601. One end of the tension spring 603 is connected to the locking pin 602, and the other end is connected to the rotating sleeve 601. When the tension spring 603 is in its natural state, the lower end of the locking pin 602 will extend into the locking hole 401 on the mud removal plate 4, thereby firmly locking the mud removal plate 4.

[0023] A chute 301 and an unlocking push plate 5 are provided on the upper cover 3. The unlocking push plate 5 is arranged in the chute 301 and can freely slide in the chute 301. A return spring 302 is also arranged in the chute 301, with one end connected to the unlocking push plate 5 and the other end connected to the chute 301. A permanent magnet 501 is provided at the end of the unlocking push plate 5 adjacent to the locking mechanism 6, and the upper end of the locking pin 602 is made of a magnetic material.

[0024] When it is necessary to clean the mud adhered to the mud removal plate 4, the operator holds the push rod 2 and places the device vertically so that the lower end of the mud removal plate 4 contacts the ground. Then, the operator steps on the unlocking push plate 5 to make it close to the locking mechanism 6. The permanent magnet 501 will attract the upper end of the locking pin 602, causing it to move upward against the tension of the tension spring 603, thus disengaging from the locking hole 401 and unlocking the mud removal plate 4. At this time, the positioning seat 103, the driving seat 104, and the sliding seat 105 move downward along the mud removal plate 4 to scrape off the mud adhered to the mud removal plate 4. Subsequently, the push rod 2 is lifted upward. The mud removal plate 4 moves downward under its own gravity. When the locking hole 401 is aligned with the locking pin 602, the locking pin 602 will automatically fall into the locking hole 401 under the tension of the tension spring 603 to lock the mud removal plate 4. In practical applications, in order to prevent the mud removal plate 4 from disengaging during reset, components such as a stop block can be provided at its upper end.

[0025] The specific embodiments of the present invention described above do not constitute a limitation to the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention shall be included in the protection scope of the claims of the present invention.
