[0025] In this embodiment, the crushing roller group 2 includes an active roller and a driven roller, and the active roller and the driven roller are rotatably connected to the inner wall of the chamber of the device body 1. The active roller of the crushing roller group 2 is fixedly connected to the output end of the motor. The device body 1 is provided with a feed port 6 located directly above the crushing roller group 2, and side discharge ports 7 are respectively provided at the bottom ends of both sides of the device body 1. The material is put into the device body 1 through the feed port 6 and is crushed under the action of the crushing roller group 2, thereby breaking up the agglomerated material to avoid affecting its screening process.

[0026] In this embodiment, the screening assembly 12 includes two side connecting plates 1221 symmetrically arranged inside the device body 1, one of the side connecting plates 1221 is fixedly connected to one end of the device body 1, and the other side connecting plate 1221 is fixedly installed at one end of the side mounting block 1222, and the side mounting block 1222 is fixedly connected to one end of the device body 1 through a plurality of fastening screws 1226, each side connecting plate 1221 has two grooves in the vertical direction, and each groove is fixedly connected to a sliding column 1223, and the two side connecting plates 1221 are connected along the vertical direction. A coarse screening mesh plate 1224 and a fine screening mesh plate 1225 are arranged in sequence in the vertical direction, and both ends of the coarse screening mesh plate 1224 and the fine screening mesh plate 1225 are respectively slidably sleeved on the sliding columns 1223 on both sides, each sliding column 1223 is located on both sides of the coarse screening mesh plate 1224 and the fine screening mesh plate 1225 and is respectively sleeved with a spring, and both ends of the spring are respectively fixedly connected to one end of the inner wall of the groove of the sliding column 1223 and one end of the coarse screening mesh plate 1224 or the fine screening mesh plate 1225, and a handle 1227 is fixedly installed on one side of the side mounting block 1222.

[0027] The material crushed by the crushing roller group 2 falls on the first screening component 12 in the vertical direction for preliminary screening, wherein the first screening component 12 includes two coarse screening mesh plates 1224 and fine screening mesh plates 1225 arranged in the vertical direction, which are used to perform preliminary coarse screening and fine screening processes on the material. At the same time, in order to avoid the accumulation of materials on the coarse screening mesh plates 1224 and the fine screening mesh plates 1225, affecting the screening rate, the two ends of the coarse screening mesh plates 1224 and the fine screening mesh plates 1225 are respectively movably sleeved on the sliding column 1223 in the groove of the side connecting plate 1221, and ... The two sides of the mesh plate 1224 and the fine screening mesh plate 1225 are elastically connected to the inner wall of the groove of the side connecting plate 1221 through springs, wherein the spring is sleeved on each sliding column 1223 and symmetrically distributed along both sides of each coarse screening mesh plate 1224 and the fine screening mesh plate 1225. The mechanical vibration generated during the operation of the equipment is combined with the spring to increase its amplitude, so that the coarse screening mesh plate 1224 and the fine screening mesh plate 1225 are shaken, thereby accelerating the initial screening rate of the material on the coarse screening mesh plate 1224 and the fine screening mesh plate 1225, and also avoiding the decrease in screening rate caused by impurity accumulation.

[0028] Furthermore, one of the side connecting plates 1221 is clamped in the docking groove 9 of the docking block 10 fixedly connected to the inner wall of the device body 1, and the other side connecting plate 1221 is fixedly installed on one end of the side mounting block 1222. The two ends of the side mounting block 1222 are respectively fixed to one end of the device body 1 by a plurality of fastening screws 1226 to ensure the firmness of the connection of the first screening component 2 during the screening process. A handle 1227 is fixedly provided on one side of the side mounting block 1222, so that the staff can install and disassemble the side mounting block 1222 by holding the handle 1227, thereby cleaning the impurities on the coarse screening mesh plate 1224 and the fine screening mesh plate 1225.

[0029] In this embodiment, the drying component 3 includes a support block 31 with an arc-shaped top, and a heat-conducting block 32 is fixedly arranged on the top of the support block 31, and a plurality of first mounting blocks 111 are respectively fixedly connected on both sides of the support block 31, and each of the first mounting blocks 111 has a rectangular groove, and each of the rectangular grooves of the first mounting blocks 111 is fixedly connected to a slide rod 1111, and the second screening component 4 includes an oblique connecting plate 42 slidably sleeved with each slide rod 1111, and a plurality of oblique connecting plates 42 are respectively fixedly connected to the two ends of the oblique screening net 41, and the oblique screening net 41 is close to the bottom end of the inner wall of the device body 1. The inclined connecting plate 42 is curved, and the inclined connecting plate 42 of the inclined screening net 41 close to the bottom end of the inner wall of the device body 1 is slidably sleeved on the outside of the sliding rod 1111 fixedly connected to the top of the second mounting block 11, and the sliding rods 1111 on both sides of each inclined connecting plate 42 are sleeved with springs, and the two ends of the spring are respectively fixedly connected to one end of the inner wall of the rectangular groove of the first mounting block 111 and one end of the inclined connecting plate 42, and the two sides of the bottom end of the support block 31 are respectively fixedly connected with breathable mesh tubes 33, and the bottom end of the breathable mesh tube 33 is fixedly connected to the bottom end of the inner wall of the chamber of the device body 1, and the two sides of the breathable mesh tube 33 are respectively provided with bottom discharge ports 8.

[0030] The inclined screening net 42 is convenient for re-screening of the material. The fine material after re-screening is collected through the bottom discharge port 8 at the bottom end of the device body 1, and the coarser material after re-screening is collected through the side discharge ports 7 on both sides of the device body 1. At the same time, in order to dry the material, a chamber is opened in the support block 31 of the drying component 3, and a breathable mesh cylinder 33 is fixedly connected to the bottom end of the support block 31, and a fitted heat-conducting block 32 is arranged at the top of the chamber of the support block 31. One end of the hot air blower 5 enters the air permeable mesh tube 33 through the pipeline. On the one hand, the materials on the inclined screening meshes 42 on both sides are dried through the mesh holes of the air permeable mesh tube 33. On the other hand, the hot air flows from the chamber of the support block 31 through one end of the heat conductive block 32. The heated heat conductive block 32 can heat the materials falling after the preliminary screening of the first screening component 12, so that the materials can be dried more fully and facilitate the subsequent screening process. Among them, the top of the support block 31 and the heat conductive block 32 are both arranged as arc structures to avoid material accumulation.

[0031] Furthermore, in order to prevent materials from piling up on the inclined screening net 42 and causing clogging of the mesh holes of the inclined screening net 42, the two ends of 42 are slidably sleeved on the slide rod 1111 of the first mounting block 111 through a plurality of inclined connecting plates 41, wherein each first mounting block 111 is clamped and fixed to one end of the support block 31, and the two ends of each inclined connecting plate 41 are fixedly connected to one end of the inner wall of the rectangular groove of the slide rod 1111 through a spring. The mechanical vibration generated during the working process of the equipment is promoted by the spring to increase its amplitude, so that each inclined screening net 42 can be shaken more violently to shake off the material on the surface of the inclined screening net 42.
