[0022] In order to make the technical problems solved by the utility model, the technical scheme adopted and the technical effects reached more clear, the utility model will be further described in detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the utility model, not to limit the utility model. In addition, it should be noted that, in order to facilitate the description, only the parts related to the utility model are shown in the drawings, not all the contents.

[0023] As Figures 1-3 shown, the utility model embodiment provides a kind of filtering and crushing discharging device, the filtering and crushing discharging device is installed below dust collector funnel, the funnel of each dust collector installs one, if dust collector is multiple funnel, each funnel installs one;The filtering and crushing discharging device includes: motor 3, speed reducer 2, upper shell 9, lower shell 6, screen 8;

[0024] The upper shell 9 is arranged on the upper part of the lower shell 6, and the upper shell 9 is connected with the lower shell 6 by bolts; the upper shell 9 and the lower shell 6 form a material containing cavity; the upper shell 9 is provided with a feeding port 1; the feeding port 1 is connected with a discharge port of a dust collector hopper; the lower end of the lower shell 6 is provided with a discharge port 5; the discharge port 5 is connected with a conveying chute; the lower shell 6 is in the shape of a funnel, so that the crushed material can flow out of the discharge port 5.

[0025] The motor 3 is arranged on the outer wall of the upper shell 9 through a motor support 4. The output end of the motor 3 is provided with a speed reducer 2; the rotating shaft end of the speed reducer 2 extends into the containing cavity between the upper shell 9 and the lower shell 6 downward; the rotating shaft end of the speed reducer 2 is provided with a screen 8; the screen 8 does not contact the inner wall of the upper shell 9, and the gap between the screen and the inner wall of the containing cavity is smaller than the diameter of the blocky material; the screen 8 rotates under the action of the rotating shaft. The diameter of the holes of the screen 8 is of multiple sizes, which can be customized according to the discharge amount.

[0026] A plurality of wolf tooth crushing nails 7 are arranged on the inner wall of the upper shell 9 and the screen 8. The wolf tooth crushing nails 7 are of multiple lengths, and different lengths of wolf tooth crushing nails can be provided according to the diameter of the blocky material, so that the distance between the wolf tooth crushing nails 7 on the upper shell 9 and the wolf tooth crushing nails 7 on the screen 8 is smaller than the diameter of the blocky material, thereby facilitating the crushing of the blocky material. The length of the wolf tooth crushing nail 7 is about 10-60mm.
