Straw crusher

Abstract

The invention discloses a straw crusher. The crusher comprises a frame, a feeding port, a crushing structure, a screening structure and a discharging port; an open square cabin is fixed on the frame;the feeding port is fixed on the top of the open square cabin through screws; the crushing structure is arranged in the open square cabin and comprises a cutting roller and a crushing roller which arestaggered upwards and downwards; the screening structure comprises a hole sieve and a sweeping plate suspended above the hole sieve; a first motor and a second motor are fixed on the frame at one side of the open square cabin; the first motor is connected with the crushing roller through a conveying belt; the output shaft of the second motor is connected with a disk-shaped cam through a gear; theend face of the disk-shaped cam firmly presses against one end of a driven rod; the other end of the driven rod is hinged to the central position of the sweeping plate; the discharge port is positioned at the bottom of the open square cabin; and the side face of the hole sieve is symmetrically connected with a recovery port. Compared with the prior technical scheme, the straw crusher provided bythe invention ensures uniform texture of straw chips at the discharging port and increases the crushing effect and crushing quality.

Description

technical field [0001] The invention relates to a straw pulverizer, which belongs to the technical field of pulverizers. Background technique [0002] With the continuous development of agriculture, more and more straws are produced, and many agricultural personnel directly ignite and burn them in their farmland. Direct burning is not easy to reuse resources, resulting in large-scale waste of resources and environmental pollution. In order to solve the above problems, the current straw recycling usually uses a straw pulverizer, and the pulverized agricultural plant debris can be used to make organic fertilizer, fuel, particleboard, paper and other raw materials for various production industries, and a large number of green wastes that were difficult to be sold. Turn waste into treasure and bring into play new economic value. At the same time, it also protects the environment, improves soil, and creates good social benefits. [0003] The straw scraps pulverized by the straw ...
