Forestry impurity stirring and crushing device

Abstract

The invention relates to the technical field of smashing devices, in particular to a forestry impurity stirring and smashing device which comprises a machine box, and a first smashing mechanism and a second smashing mechanism are symmetrically arranged in the machine box. The crushed materials are fed into a second crushing mechanism through a pneumatic feeding pipe to be subjected to secondary crushing treatment, and the crushed materials which do not reach the screen standard after secondary crushing treatment are fed back into a crushing box of the second crushing mechanism through the pneumatic feeding pipe to be subjected to secondary crushing treatment till the crushed materials penetrate through the screen, so that the uniformity of stirring and crushing of the impurities is ensured; the stirring and crushing efficiency on sundries is high; and an electromagnet is arranged in a blanking pipe to be matched with a movable plate, so that metal impurities in the forestry impurities can be automatically collected and treated, and the metal impurities are prevented from entering the first crushing mechanism and the second crushing mechanism to damage mechanical parts.

Description

technical field [0001] The invention relates to the technical field of crushing devices, in particular to a stirring and crushing device for forestry sundries. Background technique [0002] In the Chinese utility model patent CN214159889U, a forestry sundry mixing and crushing device is proposed. In this technical solution, multiple groups of rotary cutters are used to cooperate with the four-layer filtering and rolling of the rolling drum to achieve a better crushing effect on the sundries, but in During the working process of the mixing and crushing device, the failure of the mechanical parts inside the device often affects the effect of stirring and crushing the sundries. For the treated pulverized materials, the uniform particle size cannot be guaranteed, and the pulverization effect cannot be achieved. The mixed material in the crushed material will also bring some troubles to the subsequent processing of the crushed material. In addition, the device cannot know the sig...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a forestry sundries stirring and crushing device, which solves the problem that the forestry sundries stirring and crushing device currently used cannot ensure the uniformity of the sundries and crushed materials, and at the same time cannot correct the failure of mechanical parts inside the device. A timely alarm signal is issued, which leads to the problem that the internal parts of the stirring and crushing device are prone to damage
