Automatic control device for reducing header loss of wheat harvester and control method of automatic control device

Abstract

The invention discloses an automatic control device for reducing header loss of a wheat harvester and a control method of the automatic control device. The automatic control device is used in cooperation with a rack, a header, a cutting knife, an auger, a reel, a reel support, a reel lifting oil cylinder and a reel driving motor of the harvester, and comprises a running speed sensor, a header height sensor, a reel height sensor, a reel rotating speed sensor and a crop height detection device, wherein the crop height detection device is connected to a crop height detection leveling device used for guaranteeing that the crop height detection leveling device is always in a horizontal state, and under the control of a harvester controller and a PID controller, the rotating speed of a reel, the height of the reel and the height of the header can be automatically adjusted according to the running speed of the harvester, so that the reel can vertically enter the harvester all the time and is prevented from beating wheat ears, the reel position is always located at the upper position of the gravity center after straw is cut off, and the grain loss caused by beating the wheat ears by the reel and other losses caused by disordered and crowded straw feeding are further reduced.

Description

technical field [0001] The invention relates to the technical field of wheat harvesters, in particular to an automatic control device capable of reducing header loss, and also relates to an automatic control method of the automatic control device. Background technique [0002] my country is a big country of food production, and food production is directly related to the basic life of the people in the country. Therefore, the field of agricultural food production is one of the most important areas in our country. With the development of agricultural technology, more and more automated agricultural equipment has been developed and put into the planting, management and harvesting of agricultural production. The wheat harvester is one of the typical advanced agricultural equipment. The efficient and smooth completion of the wheat harvesting work. [0003] Although the wheat harvester has high working efficiency, there is a common phenomenon of grain loss during the harvesting p...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the mismatch between the speed of the reel and the speed of the harvester, the reel hits the ears of wheat, resulting in serious grain loss;

[0005] 2. The height of the reel does not match the height of the wheat plant. As a result, when the reel enters the wheat clump, it is not inserted vertically through the gap between the wheat plants, but hits and presses down on the ear of the wheat to enter, resulting in grain loss. , Ear loss is serious;

[0006] 3. When the wheat straw is high, the length of the wheat straw in the cut-off part is also much longer than the distance between the cutter and the auger, causing the cut wheat to rest on the top of the auger, resulting in poor feeding of the auger, and even resulting in messy congestion At the entrance of the auger feeding, the ear loss of the entire wheat ear is serious;

[0007] 4. The gap between the header and the bridge is also an important factor causing the loss of leaked grains

It can be seen that both of the above two adjustment methods have low efficiency and technical defects that increase the labor intensity of the driver, and require a high level of experience for the driver, so ordinary drivers cannot adjust and solve the corresponding problems
