Feed anti-blocking type straw pulverizer

Abstract

The invention discloses a feed anti-blocking type straw pulverizer. The feed anti-blocking type straw pulverizer comprises a smashing chamber, a feeding device and a discharging channel. The feeding device is arranged on the top of the right side of the smashing chamber and comprises a feeding inlet, a feeding screw rod and a discharging outlet. The feeding inlet is in a horn shape and is perpendicularly located above the feeding screw rod. A rotary shaft is arranged in the center inside the smashing chamber. One end of the rotary shaft is arranged inside the smashing chamber. The other end of the rotary shaft extends out of the smashing chamber. A driven wheel is arranged at the tail end of the rotary shaft and connected with a driving wheel through a transmission belt. The driving wheel is arranged on a motor, and the motor is electrically connected with a frequency changer. The feeding device is arranged to avoid the stacking and stagnated returning problems of materials to be smashed in the feed smashing process. A transmission mechanism composed of the driving wheel, the transmission belt and the driven wheel is arranged, so that compared with a transmission mode adopted in a motor part on a prior straw pulverizer, the feed anti-blocking type straw pulverizer has the advantage of being high in transmission efficiency and can achieve the transmission efficiency approaching 1: 1.

Description

technical field [0001] The invention relates to the technical field of pulverizer equipment, in particular to a feeding anti-blockage type straw pulverizer. Background technique [0002] The straw shredder is mainly composed of motor, rotating shaft, cutter mechanism, crushing chamber and other components, which can be applied to the shredding and processing of biomass such as cotton stalks, bark, branches, corn stalks, wheat straw, straw, etc., and the processed finished products It can be used for power generation, papermaking, wood-based panels, ethanol extraction, etc. It is currently the core processing equipment for straw recycling. [0003] There are certain defects in the existing straw grinder. First, when crushing and feeding, a vibrating feeder is usually used. This feeding method has the disadvantages of uneven feeding and easy hysteresis. In addition, the motor transmission part is not flexible. Adjusting the rotational speed of the rotating shaft results in a ...

Problems solved by technology

[0003] There are certain defects in the existing straw pulverizers. First of all, when pulverizing and feeding, a vibrating feeder is usually used. This feeding method has the disadvantages of uneven feeding and easy hysteresis. In addition, the motor transmission part is not flexible. Adjusting the rotation speed of the rotating shaft has greatly restricted the use of the straw kneading vermicelli machine, and the transmission efficiency is low and the power consumption of the motor is high.
