Biomass feed extruder

Abstract

The invention relates to a biomass feed extruder. An extrusion propeller assembly of the extruder comprises a propeller rear axle, a propeller front axle and a propeller outlet taper sleeve, wherein the propeller rear axle is located in an extrusion box assembly and fixedly connected with a power output shaft of a power source through a transmission mechanism, the propeller front axle and the propeller rear axle are connected and both provided with threads, the propeller outlet taper sleeve is fixed to the front end of the extrusion box assembly, and the propeller front axle is located in a conical hole of the propeller outlet taper sleeve; a hopper welding part is fixed above the extrusion box assembly, a stirring shaft of a feeding and weed pulling mechanism is connected with the power output shaft of the power source through the transmission mechanism, the stirring shaft and a stirring plate are located in the extrusion box assembly, and the stirring plate is fixed to the front end of the stirring shaft; the cross section of the stirring plate is in the shape of a broken line, and the left portion and the right portion of the stirring plate are parallel to each other. By the adoption of the biomass feed extruder, accumulation and blocking of materials can be effectively avoided, and production efficiency is high.

Description

technical field

[0001] The invention belongs to the technical field of feed processing machinery and relates to a biomass feed extruder. Background technique

[0002] Straw extruder is the preferred feed processing machine for cattle, sheep, deer farms and professional breeding households. It is mainly used to process straw materials to turn them into fine feed that livestock love to eat, and improve the feed intake and absorption rate of livestock.

[0003] Chinese Patent Gazette discloses a "straw puffing machine" (application number: 02144553.2, publication date: May 26, 2004). The extruder is mainly composed of a shell, an auger, a feeding and cutting mechanism and a power source;

[0004] When in use, the straw is fed from the hopper, cut off under the joint action of the hob and the fixed cutter, and then enters the auger cavity of the shell. The high-speed rotation of the auger pushes the material forward, so that water is added at the same time to prevent the feed ...
