[0031] Furthermore, the first latch teeth 404 are arranged in twelve groups and are distributed at equal intervals, and the first fixed grooves 407 are arranged in twelve groups and are distributed at equal intervals. By setting up twelve groups of first latch teeth 404, the force on each group of first latch teeth 404 can be made more uniform, and by setting up twelve groups of first fixed grooves 407, the twelve groups of first latch teeth 404 can be fitted one by one.

[0032] Furthermore, the first fixed block 403 is fixedly connected to the first fixed base 406 through the first through hole 405, the first threaded hole 408, and the first bolt 409. The first threaded holes 408 are arranged in eight groups.

By arranging four groups of first blades 413, the working efficiency of the first blades 413 can be improved, thereby improving the efficiency of soil crushing.

[0034] Furthermore, the dust removal mechanism 5 includes a dust suction groove 501 opened at the top of one side of the chassis 1, a first filter screen 502 is movably abutted on one side surface of the dust suction groove 501, a third bolt 503 is threadedly connected to one side surface of the dust suction groove 501, a dust suction sleeve 504 is movably abutted on one side surface of the chassis 1, a fourth bolt 505 is threadedly connected to one side surface of the chassis 1, a dust collecting bag 506 is movably sleeved on one side of the inner surface of the dust suction sleeve 504, a ventilation pipe 507 is fixedly connected to one end of the dust suction sleeve 504, a dust suction bucket 508 is fixedly connected to one end of the ventilation pipe 507, a first sliding groove 509 is opened inside the dust suction bucket 508, a second sliding groove 510 is opened inside the dust suction bucket 508, and a third fixed groove 511 is opened inside the dust suction bucket 508. 1, a fourth fixed groove 512 is provided inside the dust collection bucket 508, a first sliding block 513 is slidably connected to the surface of the first sliding groove 509, a second sliding block 514 is slidably connected to the surface of the first sliding groove 509, a third sliding block 515 is slidably connected to the surface of the first sliding groove 509, a sealing ring 516 is movably sleeved on the surface of the fourth fixed groove 512, a second filter screen 517 is fixedly connected to one side of the first sliding block 513, a driving fan 518 is fixedly connected to one side of the second sliding block 514, a third filter screen 519 is fixedly connected to one side of the third sliding block 515, and a sealing cover 520 is threadedly connected to one side of the surface of the dust collection bucket 508. During use, when the soil block crushing device is in operation, the soil blocks in the chassis 1 pass through the first After the blade 413 and the second blade 425 are processed, some dust will be generated, and the dust will diffuse outward from the inside of the chassis 1. At this time, the driving fan 518 of the dust removal mechanism 5 can be started. The starting of the driving fan 518 will suck the dust raised inside the chassis 1 from the first filter 502 into the dust suction groove 501, and the filtered air inside the chassis 1 will be sucked into the dust collecting bag 506 for filtering again, and then the processed air will be sucked into the ventilation pipe 507 and sent to the dust collection bucket 508. At this time, the internal air of the chassis 1 will be filtered again by the second filter 517, and then the internal air of the chassis 1 will pass through the driving fan 518, and finally filtered by the third filter 519, and then the internal air of the chassis 1 will be discharged from the bottom of the sealing cover 520. The dust collecting device 508 is outside the box 1, thereby achieving the effect of dust removal of the internal air of the box 1. When it is necessary to replace or disassemble any component in the dust removal mechanism 5, it is only necessary to manually unscrew the sealing cover 520 from the dust collection bucket 508 when the soil crushing device and the driving fan 518 are stopped. Here, the second filter screen 517 is taken as an example. By manually moving the second filter screen 517, the movement of the second filter screen 517 will drive the first sliding block 513 to move. When the first sliding block 513 is lifted from the bottom of the third fixed groove 511 to the top, the first sliding block 513 can slide in the second sliding groove 510. When the first sliding block 513 slides from the second sliding groove 510 to the position of the first sliding groove 509, the second filter screen 517 can be taken out.Thereby, any component in the dust removal mechanism 5 can be replaced or disassembled.

[0035] Furthermore, the second fixing block 416 is fixedly connected to the second fixing base 419 through the second through hole 418, the second threaded hole 421, and the second bolt 422. The second threaded holes 421 are arranged in eight groups. Through the arrangement of the second fixing block 416, the second through hole 418, the second threaded hole 421, the second bolt 422, and the second fixing base 419, the second fixing block 416 can better transmit the rotational motion to the second fixing base 419. Through the arrangement of eight groups of second threaded holes 421, the connection between the second fixing block 416 and the second fixing base 419 can be made more secure.

[0036] Furthermore, the first transmission shaft 410 is connected to the bearing of the chassis 1, and the second transmission shaft 423 is connected to the bearing of the chassis 1. Through the setting of the first transmission shaft 410 and the chassis 1, the chassis 1 can ensure the normal operation of the first transmission shaft 410, and through the setting of the second transmission shaft 423 and the chassis 1, the chassis 1 can ensure the normal operation of the second transmission shaft 423.

[0037] In actual use of the crushing device, by starting the first drive motor 401 and the second drive motor 414, the soil blocks to be crushed are put into the feeding port 2, and the soil blocks transported into the chassis 1 from the feeding port 2 will be crushed by the first blade 413. After being crushed by the first blade 413, the soil blocks will fall to the bottom of the chassis, so that the second blade 425 will crush the soil blocks crushed by the first blade 413 again to achieve the effect of secondary crushing, thereby improving the crushing efficiency of the soil blocks. When it is necessary to replace or disassemble any component in the crushing mechanism 4, it is only necessary to open the chassis 1 under the premise that the first drive motor 401 and the second drive motor 414 are turned off, and the first transmission shaft 410 can be replaced or disassembled by manually loosening the first bolt 409 on the first fixing block 403, and the second transmission shaft 423 can be replaced or disassembled by manually loosening the second bolt 422 on the second fixing block 416. When the soil crushing device is in operation, the chassis 1, after being processed by the first blade 413 and the second blade 525, some dust will be generated, and the dust will diffuse outward from the inside of the chassis 1. At this time, the driving fan 518 of the dust removal mechanism 5 can be started, and the internal air of the chassis 1 will be discharged from the bottom of the sealing cover 520 to the outside of the chassis 1, thereby achieving the effect of dust removal of the internal air of the chassis 1. When it is necessary to replace or disassemble any component in the dust removal mechanism 5, it is only necessary to manually unscrew the sealing cover 520 from the dust suction bucket 508 when the soil crushing device and the driving fan 518 are stopped. Here, the second filter 517 is taken as an example. By manually moving the second filter 517, when the first sliding block 513 slides from the second sliding groove 510 to the position of the first sliding groove 509, the second filter 517 can be taken out, thereby achieving the effect of replacing or disassembling any component in the dust removal mechanism 5, thereby improving the working efficiency and maintenance efficiency of the crushing mechanism 4.

[0038] Furthermore, the first filter 502 is fixedly connected to the chassis 1 by the third bolt 503, and the dust cover 504 is fixedly connected to the chassis 1 by the fourth bolt 505. Through the arrangement of the first filter 502, the third bolt 503, and the chassis 1, it is convenient to remove the first filter 502 from the chassis 1, and through the arrangement of the dust cover 504, the fourth bolt 505, and the chassis 1, it is convenient to remove the dust cover 504 from the chassis 1.

[0039] Furthermore, the first sliding groove 509 is set to four groups, the second sliding groove 510 is set to three groups, and the third fixed groove 511 is set to twelve groups. Through the setting of four groups of first sliding grooves 509, the first sliding block 513, the second sliding block 514, and the third sliding block 515 can slide more smoothly in the first sliding groove 509. Through four groups of three groups of second sliding grooves 510, the sliding between the first sliding block 513, the second sliding block 514, and the third sliding block 515 will not be affected by each other. Through four groups of twelve groups of third fixed grooves 511, the second filter 517, the driving fan 518, and the third filter 519 can be fixed more firmly in the dustbin 508.

[0040] Furthermore, the second filter 517 is slidably connected to the dust bucket 508 through the first sliding block 513 and the first sliding groove 509, and the driving fan 518 is slidably connected to the dust bucket 508 through the second sliding block 514 and the first sliding groove 509. Through the setting of the sealing ring 516, the first sliding block 513, the first sliding groove 509, and the dust bucket 508, the second filter 517 can be easily replaced or disassembled. Through the setting of the driving fan 518, the second sliding block 514, the first sliding groove 509, and the dust bucket 508, the driving fan 518 can be easily replaced or disassembled, thereby improving the disassembly of the dust removal mechanism 5.
