A combined potato digging shovel

Abstract

The invention discloses a combined potato digging shovel, which is installed on a mounting part of a shovel frame and a middle shovel; the mounting part is provided with a first transverse rail; the middle shovel is installed on the first transverse rail; An adjustment assembly, the automatic adjustment assembly includes two balance shovels, the balance shovels are respectively located on both sides of the middle shovel; when the two balance shovels are subjected to different resistances, the middle shovel is pushed to move left and right along the first transverse track until the two balance shovels are received Force balance; the automatic adjustment assembly includes a longitudinal adjustment mechanism and a horizontal adjustment mechanism installed on both sides of the middle shovel; when the resistances received by the two balance shovels are different, the longitudinal adjustment mechanism drives the balance shovel to move up and down; the balance shovel moving up and down drives the horizontal adjustment The mechanism drives the balance shovel and the middle shovel to move left and right; the invention automatically adjusts the excavation position by balancing the left and right resistance, ensuring alignment with the ridge to be excavated, and preventing the excavation shovel from missing digging.

Description

Technical field[0001]The present invention relates to the field of potato excavation shovel, in particular, to a combination of potato excavation shovel having automatic ridge function.Background technique[0002]The excavator of the potato harvester is connected to the beam of the shovel, and the driver drives harvested machines to dig potatoes, harvest potatoes, horn, harvest potatoes.[0003]There are many diverse problems in actual potato harvest, such as the angle of potato excavation of potato, which has a large effect on potato excavation, so ZL2015105956209 discloses a mining shovel for harvesting potato, tilt adjustment mechanism and shovel The angular adjustment mechanism regulates the excavation shovel to reduce traction resistance and power consumption when harvesting potatoes.[0004]However, the above-mentioned potato excavation shovel cannot be automatically adjusted to the ridge. It encounters a curved ridge or driver's operation harvesting machine unskilled, resulting in ...

AI Technical Summary

Problems solved by technology

[0003] There are many kinds of problems in actual potato harvesting. For example, the angle of potato digging shovel has a great influence on potato digging. Therefore, ZL2015105956209 invention patent discloses a digging shovel for harvesting potatoes. Angle adjustment mechanism adjusts the digging blade to reduce drag resistance and power consumption when harvesting potatoes

[0004] However, the above-mentioned potato digging shovel cannot be automatically adjusted to the ridge, and if it encounters a curved ridge or the driver is unskilled in operating the harvester, a part of the ridge is excavated by the excavator, and another part of the same ridge is not excavated, resulting in missed harvest of potatoes. , reduce the yield of potatoes or need to re-harvest again, increase the workload, which is not conducive to the harvest of potatoes

[0005] At present, the method of aligning the ridges of the potato harvesters on the market is mostly to determine the deviation through detection, and then use the hydraulic cylinder to drive and control the entire excavator to align the ridges. The structure is complex and the cost is high.
