[0026] The working principle and use process of the present invention: Figure 1 In the state shown, the power of the movable heater 27 is turned on to make the movable heater 27 energized and heated, and then the rotatable metal knife 74 is driven to rotate through the power output device 70, and then the coffee beans to be crushed (hereinafter referred to as materials) are put into the metal processing tube 6 through the inclined feeder 8, and then the coffee beans are crushed by the high-speed rotating rotatable metal knife 74. During the crushing process, the second retractable power output member 72 is controlled to continuously extend and contract, so that the rotatable metal knife 74 moves vertically back and forth, so that the rotatable metal knife 74 crushes at different heights, thereby improving the crushing effect of the material; Secondly, in the process of crushing materials, the first retractable power output member 292 is controlled to continuously extend and contract in a small range. At this time, the filter screen 26 continuously performs vertical reciprocating movement. The vertical reciprocating movement of the filter screen 26 realizes rapid screening of materials, so that the crushed materials that meet the standards pass through the filter screen 26 and are discharged to the outside through the installed metal pipe 28. In the process of discharge, the movable heater 27 is used to quickly dry the materials, and the vertical reciprocating movement of the movable heater 27 can improve the drying effect of the materials. In addition, the vertically reciprocating filter screen 26 will throw up the materials accumulated above it during the upward movement, thereby further improving the contact effect between the materials and the rotatable metal knife 74, and further improving the crushing effect of the machine on the materials. In addition, the vertical reciprocating movement of the filter screen 26 can effectively prevent the filter screen 26 from being blocked. In addition, during the crushing process, the first retractable power output member 292 is controlled to move downward so that the movable blocking cylinder 25 loses its blocking effect on the first inclined discharge hole 5. At this time, the substandard materials accumulated on the filter screen 26 are discharged to the top of the material conveying cover 34 through the first inclined discharge hole 5, and then the first retractable power output member 292 is further controlled to shrink. At this time, the movable blocking cylinder 25 moves downward to squeeze the first linkage transmission device 22, so that the first linkage transmission device 22 shrinks. At this time, the second linkage transmission device 33 is correspondingly greatly extended, so that the material conveying cover 34 carries the material and moves upward. The second movable blocking tube 35 will be driven to move upward to achieve blocking of the first inclined discharge hole 5, and the first movable blocking tube 10 will be lifted up by moving the material conveying cover 34 upward to release the enriching effect of the first movable blocking tube 10 on the second inclined discharge hole 11, and then the material on the material conveying cover 34 will be re-discharged into the interior of the metal processing tube 6 through the second inclined discharge hole 11, and then the first retractable power output member 292 will be controlled to extend to reset the filter screen cover 26, at this time, the first movable blocking tube 10 and the second movable blocking tube 35 will automatically reset, and the self-circulating crushing of the material will be achieved through intermittent pumping of the material; Thus, the material can be crushed in a self-circulating manner through the mutual cooperation of multiple structures, and the crushing structure can crush the material at different heights to achieve rapid and sufficient crushing of the material. Secondly, the present invention can filter the material during the crushing process, so that the qualified material can be discharged in time and dried during the discharge process to avoid unnecessary energy loss in the repeated crushing process, so that the crushing and drying effects of the crushing and drying machine are better, and the use of the machine is more environmentally friendly. In addition, the present invention has a simple structure, is easy to use, and is worthy of promotion and use.
