Threshing pulverizer

Abstract

The invention discloses a threshing pulverizer. The threshing pulverizer comprises a shell body, a cover body, multiple stabbing needle assemblies, multiple threshing cylinders, a plurality of roll shaft assemblies, a conveyor belt assembly, a vibration screen and a grinding assembly, wherein a powder discharging outlet is formed in the bottom surface of the shell body, a cob body material discharging outlet is formed in one side of the shell body, and a plurality of first air cylinders are arranged on the top surface of the shell body; the stabbing needle assemblies comprise first motors, second air cylinders and push cylinders, multiple columns of horizontal U-shaped files are distributed evenly on inner walls of the threshing cylinders, and the roll shaft assemblies include a roll shaftand multiple pairs of second roll shafts; corncob bodies can be guided out of the shell body through the conveyor belt assembly, and the grinding assembly includes a material leakage plate, a grinding plate and at least two pairs of screws and grindstones. Through the threshing pulverizer, quick, efficient and assembly line-type threshing and grinding can be achieved, corn kernels, corncob bodiesand flying dust can be separated effectively, working procedures are reduced, the work efficiency is improved, and maintenance and preservation are facilitated.

Description

technical field [0001] The invention relates to the field of agricultural machinery. More specifically, the present invention relates to a threshing grinder. Background technique [0002] Corn is the third crop in my country after rice and wheat, and crop harvesting is an important link in agricultural development. The corn thresher is a kind of agricultural machinery, mainly used to separate the dried corn kernels from the corncobs. There are some problems in the conventional corn thresher: the motor rotates at high speed, the corn hits the drum and threshes, and the corn threshing is uneven, causing the cob containing a small amount of remaining corn kernels to be discharged, and the corn kernels also contain a small part of crushed corn Cobs, resulting in more impurities in the processed corn kernels, which need to be filtered and sorted many times, and have no function of grinding the corn into cornmeal. Contents of the invention [0003] It is an object of the pres...
