Rice hull pulverizer for rice mill

Abstract

This utility model discloses a rice husk crusher for a rice mill, including a support frame, a feeding hopper mounted on the support frame, and a material pushing mechanism below the feeding hopper. The material pushing mechanism includes a guide cylinder inserted into the feeding hopper, and a first servo motor fixedly mounted on the left end of the guide cylinder. The output shaft of the first servo motor is connected to a first auger via a coupling. This invention relates to the field of rice husk crushing technology. By setting a crushing disc and an auxiliary disc to cooperate, the distance between the crushing disc and the auxiliary disc is slightly smaller than the required size of the crushed rice husks. This prevents rice husks that do not meet the required crushing size from being thrown out through the gap between the crushing disc and the auxiliary disc, thus ensuring that the crushed rice husks meet the crushing requirements. The first auger drives the rice husks to move and pass through the auxiliary disc and the crushing disc, and the second auger drives the rice husks in the feeding hopper into the guide cylinder, ensuring the continuity of rice husk crushing.

Description

Technical Field

[0002] The outer husk of rice. It can be used to make soy sauce, wine, and fuel. It can also be bagged for growing oyster mushrooms. The physicochemical properties of rice husks: Rice husks consist of several parts, including the outer glume, inner glume, glumes, and rachis. The outer glume has bristle-like hairs at the top. The true rice husk is composed of coarse, thick-walled cells, approximately 24-30 micrometers thick. Rice husks are rich in cellulose, lignin, and silica, with relatively low fat and protein content. The chemical composition varies depending on the rice variety, region, and climate. Rice husks consist of the inner glume and a larger outer glume. Rice husks are 5-10 mm long, 2.5-5 mm wide, and 23-30 μm thick, with colors ranging from yellowish-brown, golden yellow, yellowish-brown, to reddish-brown. Rice husks need to be crushed before use.

[0003] Existing rice husk grinders use a stirring shaft to drive the grinding blades to rotate inside the grinding vessel, thereby grinding the rice husks. However, the grinding of rice husks is not sufficient, and often mixed with whole rice husks and larger rice husk particles. Utility Model Content
