Two springs 15 are respectively installed on the outer periphery of the slide bar 14. One spring 15 on the same slide bar 14 is located on the upper side of the screening plate 8, and the other spring 15 is located on the lower side of the screening plate 8. One end of the spring 15 is fixedly connected with the screening plate 8, and the other end of the spring 15 is fixedly connected with the corresponding slide bar 14. The baffle plate 16 is fixedly installed on the screening plate 8 through several connecting rods, and several levers 17 are fixedly installed on a second rotating shaft 18 close to the baffle plate 16. In this embodiment, the number of the levers 17 is two, and the two levers 17 are symmetrically distributed at the front and rear ends of the corresponding second rotating shaft 18. The utility model has a simple structure and an ingenious design. When the crushing blade 7 rotates, it can drive the screening plate 8 to vibrate up and down through the lever 17 and the baffle plate 16, so as to vibrate out the solid waste stuck in the sieve hole on the screening plate 8, thereby solving the problem of solid waste blocking the screening plate 8, meeting market demand, and being suitable for promotion. When the utility model is used, the first drive motor 5 and the drive device are started, and the solid waste is poured into the crusher chassis 1 from the feed hopper 2. The output shaft of the first drive motor 5 rotates to drive the first rotating shaft 3 and the shearing blade 4 to rotate. The shearing blade 4 rotates to perform preliminary crushing of the solid waste. After the preliminary crushing, the solid waste falls onto the guide plate 6 and slides along the guide plate 6 to between the two crushing blades 7.

The spring 15 on the upper side of the screen plate 8 is compressed, and the spring on the lower side of the screen plate 8 is stretched until the lever 17 is separated from the baffle 16. At this time, the rotation of the lever 17 cannot drive the baffle 16 to move upward. Under the elastic force of the spring 15 itself, the screen plate 8, the connecting rod and the baffle 16 move downward. The continuous rotation of the second rotating shaft 18 can make the screen plate 8 vibrate up and down continuously, so that the solid waste stuck in the sieve holes on the screening plate can be shaken out to prevent the screen plate 8 from being blocked.

Specifically, as shown in the figure, the driving device of this embodiment includes a second driving motor 20, which is fixedly mounted on the outer wall of the crusher housing 1, one end of the second rotating shaft 18 extends out of the crusher housing 1, and a gear 21 is fixedly mounted, the two gears 21 are meshed, and the output shaft of the second driving motor 20 is fixedly connected to one of the gears 21.

The solid waste that has not been crushed to a small enough size on the upper side of the screen plate 8 rolls along the inclined screen plate 8 to the second discharge port 12, and then enters the vertical pipe 40 through the second through groove 42. The incompletely crushed solid waste is lifted to the upper end of the vertical pipe 40 by the spiral blade 44, and then enters the pulverizer case 1 through the first through groove 41 and the feed port 47 to be crushed again.

Further, as shown in the figure, the lower end of the vertical pipe 40 of this embodiment is provided with a third discharge port 50, and the inner circumference of the third discharge port 50 is provided with a thread and a sealing cover 51 is installed with the thread. When the solid wastes left on the screen plate 8 do not need to be further crushed, the first drive motor 5 is turned off, and the solid wastes on the screen plate 8 roll down along the inclined screen plate 8 to the second discharge port 12, and then enter the vertical pipe 40 through the second discharge port 12 and the second through slot 42, and the sealing cover 51 is screwed, the third discharge port 50 is opened, and the solid wastes in the vertical pipe 40 fall into the second storage box 13 through the third discharge port 50.
