Automatic adjustment row-controlled device of peanut combine

Abstract

The invention discloses an automatic adjustment row-controlled device of a peanut combine. The device comprises a supporting frame arranged on a rack. A positioning electric cylinder is arranged on the supporting frame, the positioning electric cylinder is a double-acting electric cylinder, and the left end and the right end of a telescopic rod of the positioning electric cylinder stretch outwards along the left side and the right side respectively and are fixedly connected with corresponding installing frames. Each installing frame is provided with a grain lifter, a divider, a detection device and a digging shovel. The detection devices are used for detecting extrusion force of the two side walls of a furrow between two adjacent ridges and transmitting extrusion force signals to a control system, the control system makes a judgment and controls the positioning electric cylinder to act, and the telescopic rod of the positioning electric cylinder moves left and right to drive the grain lifters, the dividers, the detection devices and the digging shovels on the two installing frames to move left and right synchronously. The device has the advantages that the digging shovels and other working parts on the two installing frames are driven by the positioning electric cylinder to move left and right synchronously, and automatic adjustment row-controlled operation is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an automatic adjustment alignment device for a peanut combine harvester. Background technique [0002] Compared with major crops such as rice, wheat and soybeans, the development of peanut production mechanization lags behind seriously, especially in the harvesting process, which currently mainly relies on manual and semi-mechanized completion, with high labor intensity, high operating costs, low efficiency, and large losses. About 1 / 3 of the whole process, the operating cost accounts for about 50% of the total production cost, which has become the main "bottleneck" of the industry's production development and industrial growth. Ridge farming is the main method of peanut planting in my country. Peanut fruit is buried in the ground, which is different from ground crops such as rice, wheat, and corn.

[0002] Compared with major crops such as rice, wheat and soybeans, the development of peanut production mechanization lags behind seriously, especially in the harvesting process, which currently mainly relies on manual and semi-mechanized completion, with high labor intensity, high operating costs, low efficiency, and large losses. About 1 / 3 of the whole process, the operating cost accounts for about 50% of the total production cost, which has become the main "bottleneck" of the industry's production development and industrial growth

Ridge farming is the main method of peanut planting in my country. Peanut fruit is buried in the ground, which is different from ground crops such as rice, wheat, and corn. It needs to be dug to harvest when harvesting. Due to the non-standard planting agronomy and the non-uniform mode of ridge farming in various places, the harvest process cannot Realize automatic alignment. If there is a deviation in the forward direction of the digging shovel during digging and harvesting, it will cause problems such as large missed harvest and low efficiency during the harvesting process. In order to improve the mechanized operation level of peanut harvesting, it is urgent to study the automatic alignment of harvesting machinery technology

At present, my country lacks both mature technology and basic research in the field of automatic peanut mechanized harvesting research. The development of automatic peanut mechanized harvesting devices is of great significance for improving the sensitivity, adaptability and reliability of peanut mechanized harvesting.
