A shredder for crushing plant stems

Abstract

The invention discloses a crusher for crushing plant stalks. The crusher comprises a shell; a feeding hopper is arranged at the upper end of the shell; a crushing chamber is arranged below the feedinghopper; crushing rollers are arranged in the crushing chamber; a motor for driving the crushing rollers is arranged outside the shell; crushing teeth are annularly arranged on the outer surfaces of the crushing rollers; ejector pins are arranged at intervals between the adjacent crushing teeth; the tail ends of the ejector pins are fixedly arranged on rubber sleeves; a mounting base is arranged outside the shell; an oil cylinder is arranged on the mounting base; a hole expanding rod is arranged on a piston rod of the oil cylinder and is movably inserted into the rubber sleeves; and a discharging hopper is arranged below the crushing chamber. The crusher for crushing the plant stalks has the advantages that plant residues adhering to the crushing rollers can be separated from the crushingrollers, and therefore the crushing effect can be ensured.

Description

technical field [0001] The invention belongs to the field of hemp and plastic manufacturing, in particular to a crusher for crushing plant stems. Background technique [0002] Wood-plastic panels (wood-plastic composite panels) are widely used in furniture, indoor and outdoor decoration, vehicle and ship decoration, etc. In order to further improve the performance of wood-plastic panels, a certain proportion of plant fibers such as ramie stalks and cotton stalks are added to the raw materials of wood-plastic panels to process them into hemp-plastic panels. Before processing, it is necessary to crush the ramie stalks for subsequent mixing and other processes. When the existing crusher crushes plants such as ramie stalks, the residual branches of the plants will stick to the crushing roller, which is difficult to clean, and the accumulation of multiple layers will cause Affects the broken effect. Contents of the invention [0003] The object of the present invention is to ...
