An anti-clogging screening device for sawdust

Abstract

The invention discloses anti-blockage screening equipment for saw dust. The anti-blockage screening equipment comprises a screening box. A motor base is fixedly connected to the left side of the bottom in the screening box. The upper portion of the motor base is fixedly connected with a motor. The output end of the motor is fixedly connected with a lower rotation shaft. A crank throw is fixedly connected to the middle portion of the lower rotation shaft. The middle portion of the crank throw is rotationally connected with a lower connecting rod. The upper portion of the lower connecting rod isrotationally connected with an upper connecting rod. The lower portion in the screening box is fixedly connected with a lower material guiding plate. First-level discharging ports are formed in the outer side of the lower material guiding plate in a left-right symmetry manner. The upper connecting rod penetrates the lower material guiding plate and is in sliding connection with the lower materialguiding plate. Second-level discharging ports are symmetrically formed in the left side and the right side of the upper portion of the screening box and are located above the first-level dischargingports. Compared with the prior art, the anti-blockage screening equipment has the beneficial effects that the structure is simple, usage is convenient, saw dust can be effectively screened during usage, the saw dust fineness degree is guaranteed, the situation that usage is not convenient enough is avoided, and the anti-blockage screening equipment is worthy of popularization.

Description

technical field [0001] The invention relates to sawdust processing equipment, in particular to anti-clogging screening equipment for sawdust. Background technique [0002] Sawdust refers to the foamy sawdust of the tree itself that is scattered from the tree due to cutting during wood processing. Wood processing, using wood as raw material, is mainly processed by mechanical or chemical methods, and its products still maintain the basic characteristics of wood. [0003] In the forest industry, the wood processing industry and the chemical processing of forest products are both follow-up industries of forest harvesting and transportation, and are important departments for the comprehensive utilization of wood resources. [0004] Sawdust has a wide range of uses, and is needed in various industries such as industry, agriculture, and forestry. Sawdust is a good fertilizer for cultivation, and it is also a good auxiliary material for industrial oil removal. Therefore, the amount...
