Combined potato digging shovel

Abstract

The invention discloses a combined potato digging shovel. The combined potato digging shovel comprises a mounting piece and a middle shovel body which are arranged on a shovel frame; the mounting piece is provided with a first transverse track; the middle shovel body is arranged in the first transverse track; the two sides of the middle shovel body are provided with automatic adjusting assemblies,each automatic adjusting assembly comprises two balancing shovel bodies, and the balancing shovel bodies are located at the two sides of the middle shovel body respectively; when the two balancing shovel bodies are subjected to different resistances, the middle shovel body is pushed to move left and right along the first transverse track until the forces of the two balancing shovel bodies are balanced; each automatic adjusting assembly comprises a longitudinal adjusting mechanism and a transverse adjusting mechanism which are arranged at the two sides of the middle shovel body; when the two balancing shovel bodies are subjected to different resistances, the longitudinal adjusting mechanisms drive the balancing shovel bodies to move up and down, and the balancing shovel bodies moving up and down drive the transverse adjusting mechanisms to drive the balancing shovel bodies and the middle shovel body to move left and right. The combined potato digging shovel automatically adjusts the digging position, ensures aligning of a to-be-dug ridge and prevents digging missing of the digging shovel by balancing the left and right resistances.

Description

technical field [0001] The invention relates to the technical field of potato digging shovels, in particular to a combined potato digging shovel with automatic ridge alignment function. Background technique [0002] The digging shovel of the potato harvester is connected to the crossbeam of the shovel frame, and the driver drives the harvester to dig the potatoes ridge by ridge in the potato field to harvest the potatoes. [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. The 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 op...

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.
