Vertical multi-stage straw grinder

Abstract

A vertical type multistage straw pulverizer comprises a machine base and is characterized in that an inner screen drum formed by a bottom-layer drum body, a middle-layer drum body and an upper-layer drum body, a square-tooth hammer pulverizing cutter, a groove hammer pulverizing cutter, a small curve blade pulverizing cutter, a large curve edge pulverizing cutter and a roughing cutter are arranged in an outer machine shell, with a top cover, on a machine base; the square-tooth hammer pulverizing cutter and the groove hammer pulverizing cutter are arranged in the bottom-layer drum body, the small curve blade pulverizing cutter and the large curve edge pulverizing cutter are arranged in the middle-layer drum body, the roughing cutter is arranged in the upper-layer cylinder body, and the square-tooth hammer pulverizing cutter, the groove hammer pulverizing cutter, the small curve blade pulverizing cutter, the large curve edge pulverizing cutter and the roughing cutter are arranged on a transmission shaft of a driving motor one by one in a series mode; screen holes are evenly distributed in the peripheral wall and the inner bottom face of the bottom-layer drum body, the peripheral wall and the inner bottom face of the middle-layer drum body and the peripheral wall and the inner bottom face of the upper-layer drum body; the bottom-layer drum body, the middle-layer drum body and the upper-layer drum body are fixedly connected through flange bases; an upper left spring and a lower left spring are arranged on the overlapped upper end face and the lower end face of a left lower middle layer vibration arm and a right lower middle layer vibration arm of the middle-layer drum body, and an upper right spring and a lower right spring are arranged on the overlapped lower end face and the upper end face of a left bottom layer vibration arm and a right bottom layer vibration arm of the bottom-layer drum body; the upper left spring, the lower left spring, the upper right spring and the lower right spring are connected to a left vibration arm base and a right vibration arm base respectively through bolts and adjusting nuts; a left vibration motor and a right vibration motor are arranged on the left vibration arm base and the right vibration arm base respectively. The vertical type multistage straw pulverizer is used for straw pulverizing.

Description

technical field [0001] The invention relates to a straw grinder, in particular to a vertical multistage straw grinder. Background technique [0002] Commonly used straw grinders, one is simple in structure, and two sets of equipment are required for rough cutting and crushing, which reduces the crushing efficiency and the crushing effect is not ideal. Another is that the structure is complex, troublesome to manufacture, and the cost of use is high. In addition, the particles of the existing straw grinder only reach 5-15 mm when the straw is crushed, so that the effect of reusing the crushed straw is limited to a certain extent. Therefore, it is necessary to make a reform for the existing straw pulverizer. Contents of the invention [0003] The object of the present invention is to provide a vertical multi-stage straw grinder, which not only can crush straw effectively, but also has reasonable structure, high crushing efficiency and convenient operation. [0004] In orde...
