Threshing and smashing device for agricultural cereal straw

Abstract

The invention discloses a threshing and smashing device for agricultural cereal straw. The device comprises a comprehensive treatment chamber and main supporting shelves; a feeding port is welded to the left side of the upper portion of the comprehensive treatment chamber, a straw outlet is welded to the right side of the bottom of the comprehensive treatment chamber, and the main supporting shelves are fixedly installed at the two sides of the bottom of the comprehensive treatment chamber; a motor A is installed at the right side of the comprehensive treatment chamber, a rotary wheel is installed below the motor A, the motor A is connected with the rotary wheel through a conveying belt, partition plates are installed at the upper and lower sides in the middle inside the comprehensive treatment chamber, and the motor A is rotatably connected with a main rotary shaft inside the comprehensive treatment chamber through bolts. According to the threshing and smashing device for the agricultural cereal straw, M-shaped spike teeth are combined with a semi-cylindrical baffle to make the whole threshing link completed in one cylindrical structure, and the contact area of the spike teeth andthe straw is increased through the M-shaped spike teeth, so that the threshing effect is greatly improved.

Description

technical field [0001] The technical field of agricultural grain harvesting of the present invention is specifically an agricultural grain straw threshing and crushing device. Background technique [0002] Grain threshing is one of the most important links in the crop harvesting process. After harvesting, the grains of the crops are removed from the ears, and other extruded objects such as short stalks, chaff, debris and grains are removed as much as possible. seperate. Straw is the remaining stems and leaves of gramineous crops such as sorghum, corn, rice and wheat after threshing. Since modern times, the demand for straw in rural areas has become less and less, which has led to the problem of burning straw on the spot, which will lead to Air pollution, waste of resources, fires, and impact on aviation vision, so straw crushing is also an important link. [0003] Generally, threshing and crushing devices on the market perform threshing and crushing at the same time, which...
