Technical Field
[0001] The utility model relates to the technical field of crushing devices, and more specifically, to a waste soil crushing device. Background Technique
[0002] A crushing device refers to a device that pulverizes materials to facilitate reprocessing.
[0003] At the same time, in the existing construction process, in order to facilitate transportation, a temporary road will be built. Therefore, some waste soil will be collected, then crushed and mixed with concrete and laid on the road surface to form a temporary road. However, when using a crusher to crush the waste soil, due to the flexibility and viscosity of the mud blocks, a large amount of them will adhere between the crushing blocks on the side wall of the crushing shaft, resulting in an impact on the crushing of the mud blocks. Content of the Utility Model
[0004] The purpose of the utility model is to provide a waste soil crushing device, which solves the problem that when the crushing device crushes waste soil, due to the flexibility and viscosity of the mud blocks, a large amount of them will adhere between the crushing blocks on the side wall of the crushing shaft during the crushing process, resulting in a decrease in the crushing effect of the crushing shaft and thus affecting the crushing quality.
[0005] The utility model is realized through the following technical solutions:
[0006] The utility model provides a waste soil crushing device, which includes a main body. There is a feed inlet at the top of the main body. On both sides of the inner wall near the top of the main body, there are sliding walls. Inside the main body, there is a crushing shaft connected. There are crushing blocks on the side wall of the crushing shaft. There is a displacement groove on the inner wall of the main body. Above the displacement groove on the inner wall of the main body, there is a reset groove. A cleaning block is connected between the displacement groove and the reset groove. On one side of the bottom of the cleaning block, there is a cleaning brush. On one side of the top of the cleaning block, there is a displacement component, and the displacement component is activated by being squeezed by the crushing block.
[0007] Preferably, the reset groove is a groove with a length less than that of the displacement groove.
[0008] Preferably, convex blocks are separately arranged at the upper and lower ends of the cleaning block to cooperate with the displacement groove and the reset groove.
[0009] Preferably, one end in the middle of the reset groove is connected to the convex block on one side of the top of the cleaning block through a spring.
[0010] Preferably, the displacement component includes a squeezing block and a squeezing arc surface. The squeezing block is arranged on one side of the top of the cleaning block, and the squeezing arc surface is arranged at the bottom of the squeezing block.
[0011] Preferably, the squeezing block is on the top side close to the crushing block.
[0012] Preferably, the squeezing arc surface is an arc surface inclined at the bottom of the squeezing block.
[0013] The technical solution of this utility model has at least the following advantages and beneficial effects:
[0014] 1. The cleaning block in the device can clean the soil attached to the surface by rotating the crushing shaft. At the same time, the lateral displacement of the cleaning block can clean the soil attached between the crushing blocks, so as to ensure that too much soil is attached between the crushing blocks when crushing mud blocks, which will affect the crushing.

[0019] The following is combined with Figures 1 to 3 This utility model will be described in detail.
[0020] A waste soil crushing device includes a body 1, a feed inlet 101 at the top of the body 1, sliding walls 102 on both sides of the inner wall of the body 1 near the top, a crushing shaft 2 connected inside the body 1, crushing blocks 201 on the side wall of the crushing shaft 2, a displacement groove 103 on the inner wall of the body 1, a reset groove 104 on the inner wall of the body 1 above the displacement groove 103, a cleaning block 3 connected between the displacement groove 103 and the reset groove 104, a cleaning brush 301 on one side of the bottom of the cleaning block 3, and a displacement component on one side of the top of the cleaning block 3. The displacement component is squeezed and moved by the crushing blocks 201.
[0021] First, the mud blocks to be crushed are poured into the feed body 1 through the feed inlet 101. Then, the mud blocks slide down the sliding wall 102 to the space between the two crushing shafts 2. The crushing shafts 2 start to rotate through the drive of the motor. The mud blocks are crushed by the misalignment of the crushing blocks 201 on the crushing shafts 2, so as to facilitate the processing and use of the mud blocks.
[0022] Furthermore, the reset groove 104 is a groove with a length shorter than the displacement groove 103. The upper and lower ends of the cleaning block 3 are respectively provided with protrusions that cooperate with the displacement groove 103 and the reset groove 104. One end of the middle part of the reset groove 104 is connected to the protrusion on the top side of the cleaning block 3 through a spring. The displacement component includes a pressing block 302 and a pressing arc surface 3021. The pressing block 302 is located on the top side of the cleaning block 3, and the pressing arc surface 3021 is located on the bottom of the pressing block 302. The pressing block 302 is located on the top side of the crushing block 201. The pressing arc surface 3021 is an arc surface that is inclined at the bottom of the pressing block 302.
[0023] While the crushing shaft 2 is rotating to crush the mud, it will rotate to the cleaning brush 301 connected to the side of the cleaning block 3. The cleaning brush 301 will sweep off the mud attached to the crushing shaft 2 to prevent the mud from sticking between the crushing blocks 201 due to its softness and affecting the crushing.
[0024] Meanwhile, during the rotation of the crushing shaft 2, the crushed block 201 rotates and abuts against the extrusion arc surface 3021 at the bottom of the extrusion block 302. Through the displacement of the crushed block 201 as it is driven, it will press against the extrusion arc surface 3021 to apply pressure, forcing the extrusion block 302 to move to one side, thereby causing the entire cleaning block 3 to move. The displacement of the cleaning block 3 causes the cleaning brush 301 to also move to a certain extent. Through the left and right displacement of the cleaning brush 301, the mud attached between the upper and lower crushed blocks 201 will be cleaned, avoiding the inability to effectively clean the mud between the upper and lower crushed blocks 201 by cleaning the mud in a single vertical direction with the cleaning brush 301.
[0025] The following is a detailed implementation process of this utility model: First, the mud blocks to be crushed are poured into the feed body 1 through the feed inlet 101. Then, the mud blocks slide down the sliding wall 102 to the space between the two crushing shafts 2. The crushing shafts 2 rotate through the drive of the motor. The crushing blocks 201 on the crushing shafts 2 are staggered and crushed to facilitate the processing and use of the mud blocks. While the crushing shafts 2 are rotating and crushing the mud blocks, they rotate to the cleaning brush 301 connected to the cleaning block 3. The cleaning brush 301 sweeps off the mud adhering to the crushing shafts 2, preventing the soft mud from adhering between the crushing blocks 201 and affecting the crushing process. As the crushing shaft 2 rotates, the crushed block 201 rotates and abuts against the compression arc surface 3021 at the bottom of the compression block 302. Through the displacement of the crushed block 201, it will squeeze the compression arc surface 3021 to apply pressure, forcing the compression block 302 to move to one side, thereby causing the entire cleaning block 3 to move. The displacement of the cleaning block 3 will also cause the cleaning brush 301 to move to a certain extent. The left and right displacement of the cleaning brush 301 will clean the mud attached between the upper and lower crushed blocks 201, avoiding the ineffective cleaning of the mud between the upper and lower crushed blocks 201 by the cleaning brush 301 alone in a single vertical direction.
