Automatic depth limiting mechanism and method and digging type harvester

Abstract

The invention discloses an automatic depth limiting mechanism and method and a digging type harvester. The automatic depth limiting mechanism includes depth limiting wheels, an angle detection device, a processing unit and an adjusting device; the angle detection device is used for obtaining the pitch angle of a machine frame of the digging type harvester; the processing unit is used for obtaining the target in-soil depth according to the pitch angle and a pre-stored correspondence rule between the pitch angle and the in-soil depth of a ploughing blade; the adjusting device is used for adjusting the depth limiting wheels according to the target in-soil depth and a pre-stored standard depth limiting value. By means of the automatic depth limiting mechanism and method and the digging type harvester, the pitch angle of the machine frame is automatically detected, the depth limiting value required by the machine is automatically judged according to the pitch angle, the automatic adjustment of the depth limiting wheel is further achieved, on one hand, active operation of drivers is omitted, and on the other hand, accurate adjustment of the depth limiting value is achieved.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an automatic depth-limiting mechanism, a method and an excavating harvester. Background technique [0002] For agricultural crops such as peanuts, sugar beets, potatoes, etc., at least part of the crops are buried in shallow soil, automatic harvesting needs to be carried out by digging harvesters. For peanuts, the harvesting devices of the peanut harvester include plows and shovels. Peanut laying device, the plow shovel is inserted into the soil to loosen the soil and shovel out the peanuts, and then the peanut laying device picks up the shoveled peanuts and arranges and clears the soil. [0003] As is known, the digging harvester is also provided with a limited depth mechanism, which is used to control the distance between the plow shovel and the wheel in the vertical direction, thereby controlling the depth of the plow shovel into the soil, thereby ensuring that it can better shovel ou...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the existing technology is that on the one hand, the adjustment of the telescopic device requires manual operation by the driver, which brings extra workload to the driver; , to achieve accurate and reasonable adjustment of the depth of the plow and shovel into the soil
