Smashing device capable of reducing flying dust and provided with good smashing effect

Abstract

The invention relates to the technical field of smashing devices, in particular to a smashing device capable of reducing flying dust and provided with a good smashing effect. The smashing device comprises a housing, wherein charge hoppers are arranged at left and right sides of the upper part of the housing; blocking plates are rotatably connected on the tops in the charge hoppers through pin rolls; springs are welded between the rear end surfaces of the blocking plates and the tops in the charge hoppers in an inclined mode; the bottom end of the housing communicates with a discharge hole; thebottom of the housing is further welded with a dustproof cover; the front side of the dustproof cover is in pushing-pulling connection to a storage drawer below the discharge hole; waste plastic is added into the housing through the charge hoppers; during adding, the blocking plates backwards extend springs for adding waste plastic when the pin rolls and the blocking plates which are rotatably connected to the charge hoppers sense weight generated by the waste plastic; and after adding is completed, the blocking plates seal the charge hoppers again by virtue of restoring force of the springs,so that generation of flying dust is reduced.

Description

technical field [0001] The invention relates to the technical field of pulverizing devices, in particular to a pulverizing device capable of reducing dust and having a good pulverizing effect. Background technique [0002] Some waste plastic crushing devices have complex structural design, large volume, high production cost, and poor effect on crushing waste plastic. [0003] In this regard, the patent application number is CN201721018121.4, which proposes a waste plastic crushing device, which mainly includes a feeding port, a feeding port, a fixed structure, a cutter and a rotating shaft. The main body of the crushing device is a cylindrical structure, one end of the main body of the crushing device has a rotating shaft, the rotating shaft runs through the main body of the crushing device, and the distance between the rotating shaft and the discharge port is 3-5 cm, the crushing device There is a cutter inside the main body, the upper end surface of the main body of the p...

AI Technical Summary

Problems solved by technology

[0005] 1. The dust-proof effect is poor: in the above scheme, the feeding port and the discharging port are all open, which can easily cause a large amount of dust raised during the crushing process to scatter in the air;
