A kind of corn thresher

Abstract

A corn thresher comprises a controller, a rack, a corn holding assembly, a threshing assembly and a screening assembly. The corn thresher is characterized in that the corn holding assembly comprises amotor, the motor drives a V belt pulley II through an output V belt, and the V belt pulley II sleeves a transmission shaft which is connected with a screw; the threshing assembly comprises a base provided with two guide rails I and a lead screw I, the lead screw I is connected with a stepping motor I, a frame is arranged on the two guide rails I slidably, a lead screw nut I matched with the leadscrew I is arranged on the lower portion of the frame, a tool holder mount is mounted above the frame and provided with two guide rails II and a lead screw II, the lead screw II is connected with a stepping motor II, a mounting board is arranged on the two guide rails II slidably and is fixedly connected with a guard board, a V-shaped groove extends out of the guard board, a toothed cutter is arranged above the guard board, a guide rod extends above the the toothed cutter and is provided with an electromagnetic clamping mechanism, and the mounting board is provided with a lead screw nut II matched with the lead screw II. The corn thresher has the advantages of improving corn threshing quality and efficiency.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a corn thresher. Background technique [0002] Corn is one of the main food and feed crops in the world, and is known as the king of feed. It has the characteristics of high per unit yield and stable total output. my country is the second largest corn producer in the world, second only to the United States. With the rapid development of science and technology in today's era, agricultural machinery has also achieved rapid development. Among them, the corn thresher greatly reduces the labor intensity of manual peeling of corn kernels in the process of corn harvesting, and its types are also increasing. Also very different. However, the traditional corn thresher is easy to squeeze the corn kernels, causing the corn kernels to be damaged, causing the corn kernels to be prone to mildew, which is not conducive to storage. If the threshing is not clean, it n...

AI Technical Summary

Problems solved by technology

However, the traditional corn thresher is easy to squeeze the corn kernels, causing the corn kernels to be damaged, causing the corn kernels to be prone to mildew, which is not conducive to storage. If the threshing is not clean, it needs to be cleaned manually

In the follow-up, the corn kernels need to be screened and sorted before they can be bagged. There are many links of manual participation and high labor intensity.

In short, the traditional corn thresher has the disadvantages of high damage rate, high seed loss rate, and low efficiency, which is not conducive to the breeding, harvesting, storage and transportation of corn seeds.

Therefore, it is urgent to develop a corn thresher with small investment and complete functions to solve the dilemma of the current traditional corn thresher
