Agricultural threshing machine

Abstract

The invention relates to an agricultural threshing machine which comprises a chamber. The chamber is internally partitioned into an upper threshing chamber and a lower discharging chamber by a vibrating screen in horizontal arrangement. The left top and the right top of the threshing chamber are provided with a feeding port and a waste outlet respectively. The bottom wall of the discharging chamber is inclined, and the bottommost end of the bottom wall of the discharging chamber is provided with a discharging port. A plurality of groups of upper and lower threshers are arranged in the threshing chamber, a frame of each upper thresher is connected with the top wall of the threshing chamber, the bottom of a frame of each lower thresher is connected with the bottom wall of the discharging chamber while the top penetrates a notch reserved in the vibrating screen, each frame is connected with a rotating shaft driven by a motor, each rotating shaft is radially provided with a plurality of swing arms, and a threshing drum is arranged at the top of each swing arm. A conveying belt is horizontally arranged at the waste outlet and provided with a straw receiving fork horizontally arranged atthe end of a frame in the chamber, a straw raising drum is arranged on the lateral side of the conveying belt and driven by a motor, a body of the straw raising drum is provided with a plurality of fork rods, and the fork rods and the straw receiving fork are staggered. The agricultural threshing machine has advantages of simple structure, great threshing effects and high efficiency.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to an agricultural thresher. Background technique [0002] The thresher is a commonly used agricultural product. The thresher is a harvesting machine that can separate the grain of the crop from the stalk. It mainly refers to the harvesting machine of the grain crop. According to the different crops, there are different types of threshers. Rice thresher" is suitable for rice threshing; corn thresher is called "corn thresher" and so on. Rice thresher is commonly known as "threshing machine". It is the most common rice thresher machine. Machinery separates rice grains from stalks. Rice threshers are divided into two categories. One is driven by manpower, which is called "manpower rice thresher", which is a semi-mechanized tool; if the rice thresher is changed to power drive, it is called "Power rice thresher", the appearance of the rice thresher greatly reduces the labor intensi...
