[0025] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0026] Next, the operation and use process of the solid waste crushing and grinding device is introduced.

[0027] During use, the operator adds the solid waste to be crushed and ground into the crushing cylinder 3 through the feed port 22, and then adjusts the gap between the upper grinding roller 5 and the lower grinding roller 11 according to the grinding coarseness requirement, controls the electric telescopic rod 6 to extend or shorten through the switch, and adjusts the gap between the lower grinding roller 11 and the upper grinding roller 5 to the required size, and then starts the motor 9 through the switch to make the rotating rod 10 drive the lower grinding roller 11 to rotate. In this process, the driven rod 15 rotates synchronously with the rotation of the rotating rod 10 through the docking of the rotating rod 10 and the connecting sleeve 16. Under the setting of the blade 23, the solid waste on the top of the partition mesh plate 13 is crushed. When the solid waste is crushed to a suitable size, it will fall into the lower hopper 19 through the discharge hole on the top of the partition mesh plate 13 and the cooperation of the scraper 17, and finally be transported by the lower hopper 19 to the feed port on the top of the upper grinding roller 5. With the high-speed rotation of the lower grinding roller 11, the crushed solid waste is ground. Finally, the ground chemical raw materials fall into the inside of the receiving frame 12 through the gap between the upper grinding roller 5 and the lower grinding roller 11, so as to achieve the effect of collecting them. When the grinding operation is completed, it needs to be When the inside of the crushing drum 3 is to be cleaned, the operator directly places the water pipe through the feed port 22 into the inside of the crushing drum 3, and then starts the motor 9 through the switch, so that the rotating rod 10 also drives the lower grinding roller 11 to rotate, and the driven rod 15 drives the scraper 17 and the brush 18 to rotate synchronously, so as to achieve the effect of cleaning the top of the material separation mesh plate 13. At the same time, the water flow will fall into the inside of the upper grinding roller 5 along the lower hopper 19, so as to clean the upper grinding roller 5 and the lower grinding roller 11. Since the bottom of the upper grinding roller 5 and the top of the lower grinding roller 11 are in the process of grinding materials, The material will be squeezed repeatedly, and stubborn material residues are easily attached to its surface. It is not cleaned thoroughly by simply washing with water. At this time, the operator starts the electric telescopic rod 6 through the switch to extend it, and allows the L-shaped fixing plate 7 to drive the mounting seat 8 and the lower grinding roller 11 to move downward as a whole, so that the lower grinding roller 11 is separated from the upper grinding roller 5, and the rotating rod 10 is separated from the connecting sleeve 16. At this time, there is a large operating space between the upper grinding roller 5 and the lower grinding roller 11. The operator can use this operating space to use a brush to clean the stubborn impurities on the surface of the lower grinding roller 11 and the upper grinding roller 5.
