The waste water after flushing is discharged through the discharge port at the bottom of the crushing box 1, and flows back to the inside of the storage box 16 for reuse, thereby reducing water waste.

[0032] In a specific embodiment, as shown in the attached Figure 1 , 4 As shown, the surface of the crushing box 1 is located at the top of the concave frame 5 and is connected to the storage frame 22. The surface of the storage frame 22 is provided with a second motor 23.

[0034] Moreover, the movable tube 20 and the nozzle 21 can be extended to the inside of the storage frame 22 under the action of the screw rod 24 and the slide rod 25, which can avoid affecting the crushing of the raw materials on the one hand, and prevent the dust after the crushing of the raw materials from affecting the use of the nozzle 21 on the other hand.

[0035] In a specific embodiment, as shown in the attached Figure 5 As shown, a filter screen 28 is slidably installed inside the storage box 16 , and support blocks 29 are provided at the bottom of the filter screen 28 on the two inner walls of the storage box 16 .

The cleaned filter 28 can be reinstalled inside the storage box 16, and the two support blocks 29 can be used to support the installed filter 28.

[0037] Working principle of this utility model:

[0038] When the above structure is used, first, the raw material of biochar is added to the inside of the crushing box 1 through the feed port 2, and the first motor 10 drives one of the shafts 7 to rotate, and under the drive of two mutually meshing gears 9, the two shafts 7 drive the corresponding crushing rollers 8 to rotate with each other, and then the raw material is crushed, and the crushed raw material falls into the inside of the collection box 4. The operator pulls the collection box 4 out of the inside of the crushing box 1, and the collected raw material can be used;

[0039] When it is necessary to wash the surface of the crushing roller 8, the operator draws out the collecting box 4 from the inside of the crushing box 1, so that the discharge port at the bottom of the crushing box 1 leaks out, and then the high-pressure pump 17 transports the water inside the storage box 16 through the connecting pipe 18 and the delivery hose 19, and the delivery hose 19 transports the water to the inside of the movable pipe 20, and finally the corresponding crushing roller 8 is washed through the two nozzles 21, and the waste water after washing re-enters the inside of the storage box 16 through the discharge port, and is reused after being filtered by the filter screen 28, thereby reducing the waste of water. The operator can draw out the filter screen 28 from the inside of the storage box 16 for cleaning;

[0040] In the process of flushing the crushing roller 8 through the two nozzles 21, the second motor 23 drives the screw rod 24 to rotate, so that the screw rod 24 drives the threaded block 26 to move, and the slider 27 is guided by the external sliding of the slide rod 25, so that the movable tube 20 drives the two nozzles 21 to move, thereby improving the flushing effect of the crushing roller 8. The movable tube 20 and the nozzle 21 can be extended to the inside of the storage frame 22 under the action of the screw rod 24 and the slide rod 25, which will not affect the use of the device;

[0041] When the two crushing rollers 8 need to be maintained, the concave frame 5 is pulled outward with force so that the card strips 12 at the top and bottom of the concave frame 5 are disengaged from the card slots 11 to which the mounting slots 6 belong. At the same time, the embedding head 14 is disengaged from the inside of the embedding slot 13, and the two magnetic blocks 15 that are magnetically attracted to each other are separated, so that the entire concave frame 5 can be pulled out from the inside of the crushing box 1, which is convenient for maintaining the two crushing rollers 8 inside the concave frame 5. During installation, it is only necessary to install the concave frame 5 inside the mounting slot 6 so that the card strip 12 slides tightly inside the card slot 11, and the embedding head 14 is embedded into the inside of the embedding slot 13 so that the two magnetic blocks 15 are magnetically attracted to each other, thereby completing the installation operation of the concave frame 5.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
