Automatic aligning device

Abstract

An automatic aligning device comprises a control system, a hydraulic device and a displacement detection device, wherein the control system and the hydraulic device are arranged on a fixing rack at the rear end of a harvest machine, the control system is connected with a harvest frame through a hydraulic cylinder, and an evacuation device and a grain lifter are arranged at the front end of the harvest frame; the displacement detection device is arranged on the grain lifter; and the displacement detection device comprises a swing rod and an angular displacement sensor, and the swing rod is connected with a singlechip used as the control system through the angular displacement sensor. The swinging angle theta of the swing rod is less than or equal to 60 degrees. The displacement detection device consisting of the swing rod and the angular displacement sensor is additionally arranged on the grain lifter and is matched with the control system to control the leftward and rightward movement of the harvest frame, so that the evacuation device can be automatically aligned; and compared with manual regulation, the automatic aligning device is more flexible, the technical requirements on an operator are lowered, and the mechanical damage rate and the fruit loss rate of crops are reduced.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, and in particular relates to an automatic alignment device for adjusting the left and right positions of harvesting machinery during the traveling process. Background technique [0002] With the development of agricultural mechanization, the research and application of harvesting machinery for tubers and rhizomes in my country is also increasing. Due to lack of standard agronomy, the distance between ridges and ridges and between rows is not uniform in different plots. Therefore, the growth positions of seedlings are often not accurately arranged in a straight line, resulting in root crops not growing on the same line. in a straight line. Existing harvesting machines for tubers and rhizomes often cannot automatically adjust the digging device according to the actual position of the seedlings in actual production, which greatly reduces the harvesting effect and production effic...

AI Technical Summary

Problems solved by technology

Due to the non-standard agronomy, the distance between ridges and ridges and between rows in different plots is not uniform, so the growth positions of seedlings are often not accurately arranged in a straight line, resulting in root crops not growing on the same line. in a straight line

Existing harvesting machinery for tubers and rhizomes often cannot automatically adjust the digging device according to the actual position of the seedlings in actual production, which greatly reduces the harvesting effect and production efficiency

Therefore, in order to avoid the fruit loss rate of crops, the operator needs to control the position of the excavating device at any time according to the specific conditions of the seedlings in the field, which not only requires high technical requirements for the operator, but also requires a lot of labor
