The sieve hole diameter of the first sieve plate 4 is larger than the sieve hole diameter of the second sieve plate 5. A crushing mechanism is arranged on the side of the feeding barrel 2. The crushing mechanism is used to crush the material screened by the first sieve plate 4. The crushing mechanism is connected to the feeding barrel 2.

[0023] like Figure 2 , Figure 3 As shown, the first sieve plate 4 and the second sieve plate 5 are both arranged in the feed barrel 2 through a vibration component, and the vibration component includes four guide shafts 10. Four guide holes are opened on the top of the first sieve plate 4 and the second sieve plate 5, and the four guide shafts 10 are respectively slidably installed in the four guide holes. Four mounting plates 9 are fixedly installed on the relative inner walls of the feed barrel 2, and the two ends of the four guide shafts 10 are respectively fixedly installed on the relative side parts of the eight mounting plates 9. The outer walls of the circumferences of the four guide shafts 10 are sleeved with compression springs 11. Through the arrangement of multiple guide shafts 10, the first sieve plate 4 and the second sieve plate 5 can be guided during vibration to avoid falling off during vibration, and through the elastic effect of multiple compression springs 11, the first sieve plate 4 and the second sieve plate 5 can be released. When the extrusion effect is exerted, the first screen plate 4 and the second screen plate 5 are quickly reset to realize the vibration screening function. The screening mechanism also includes two extrusion wheels 12. Two rectangular grooves are provided on the side of the body 1. The inner walls of the sides of the two rectangular grooves close to each other are provided with rotating holes. Rotating shafts 13 are rotatably installed in the two rotating holes. One ends of the two rotating shafts 13 are respectively rotatably installed on the inner walls of the sides of the two rectangular grooves, and the other ends of the two rotating shafts 13 extend into the feed barrel 2. The two extrusion wheels 12 are respectively fixedly sleeved on the two rotating shafts 13.

[0024] like Figure 4 , Figure 5As shown, the crushing mechanism includes a side box 3, which is fixedly installed on the side of the feed barrel 2. The side inner wall of the side box 3 and the side inner wall of the feed barrel 2 are jointly provided with an oblique drop hole, which corresponds to the position of the first screen plate 4. The side of the side box 3 is provided with two transmission grooves, which are respectively connected with the two rectangular grooves. The opposite inner walls of the side box 3 are provided with two circular holes, and two rotating rods 18 are rotatably installed in the four circular holes. The outer walls of the circumferential sides of the two rotating rods 18 are fixedly sleeved with crushing rollers 21. The two rotating rods 18 are connected by a transmission assembly, and one of the rotating rods 18 is connected to the two rotating shafts 13 by a linkage assembly. By connecting the side box 3 and the feed barrel 2, the material screened by the first screen plate 4 can directly enter the side box 3 and be crushed by the two crushing rollers 21 to a suitable size. The assembly includes two gears 20, which are respectively fixedly sleeved on the circumferential outer walls of the two rotating rods 18, and the two gears 20 are meshed and installed. A driving motor 19 is fixedly installed on the side of the side box 3, and the output shaft of the driving motor 19 is connected to the end of one of the rotating rods 18. Through the setting of the two gears 20, the two rotating rods 18 can be driven to rotate synchronously in opposite directions, thereby driving the two crushing rollers 21 to rotate synchronously in opposite directions, achieving a better crushing effect. The linkage assembly includes two sprocket wheels 17, which are respectively fixedly sleeved on the circumferential outer walls of the rotating rods 18 and the rotating shaft 13. The chains 14 are meshed and installed on the two sprocket wheels 17. Through the meshing action of the sprocket wheels 17 and the chain 14, when one of the rotating rods 18 rotates, it can drive the two rotating shafts 13 to rotate synchronously, thereby driving the extrusion wheel 12 to rotate, and the linkage effect is better.

[0025] like Figure 4 As shown, a discharge hole is provided at the bottom of the side box 3, and an inclined hole is provided on the inclined surface of the feed barrel 2. A discharge pipe 15 is fixedly installed in the discharge hole and the inclined hole. Through the setting of the discharge pipe 15, the crushed material in the side box 3 can be directly introduced into the feed barrel 2, realizing the feeding function without manual operation by the staff.

[0026] like Figure 2 As shown, a fixing plate 7 is fixedly installed on the side inner wall of the feed barrel 2, a feed motor is arranged at the bottom of the fixing plate 7, a circular shaft is fixedly arranged on the output shaft of the feed motor, an auger 8 is fixedly arranged on the circumferential outer wall of the circular shaft, and a collecting assembly includes a collecting box 6, a sliding hole is opened on the side inner wall of the feed barrel 2, the collecting box 6 is slidably installed in the sliding hole, the bottom of the collecting box 6 is fitted with the top of the fixing plate 7, and the auger 8 is driven to rotate by the feed motor to introduce the material into the machine body 1, thereby avoiding blockage during the feeding process, and through the setting of the collecting box 6, materials of smaller size can be collected for recycling to avoid waste.

[0027] The working principle and use process of the utility model are as follows: when in use, the material is thrown into the feed barrel 2, and the driving motor 19 is started to drive one of the rotating rods 18 to rotate counterclockwise. When the rotating rod 18 rotates, through the meshing action of the two gears 20, it can drive the other rotating rod 18 to rotate synchronously clockwise and drive the two rotating shafts 13 to rotate synchronously clockwise under the meshing action of the four sprocket wheels 17 and the two chains 14. When the two rotating shafts 13 rotate, they drive the two extrusion wheels 12 to rotate synchronously, and the first sieve plate 4 and the second sieve plate 5 are squeezed, so that under the elastic action of the two extrusion wheels 12 and a plurality of compression springs 11, the first sieve plate 4 and the second sieve plate 5 are driven to vibrate, thereby realizing the rapid screening function. When the first sieve plate 4 vibrates, the material larger than the required size is screened, so that it falls into the side box 3 through the oblique feed hole, and is further crushed by the two crushing rollers 21. After being crushed, it enters the feed barrel 2 through the discharge pipe 15, and there is no need for the staff to remove the crushing, thereby improving the production efficiency.

[0028] When the second screen plate 5 vibrates, materials smaller than the required size are screened and fall through the screen holes into the collecting box 6 for collection, so that materials that meet the production size fall to the bottom of the feed barrel 2 through the drop chute, and the auger 8 is driven by the feed motor to rotate, thereby realizing the feeding function, preventing blockage and improving the feeding effect.
