Continuous grain-receiving system of tracked combined harvester and control method for same

Abstract

A continuous grain-receiving system of a tracked combined harvester and a control method for the same belong to the field of agricultural machinery. The continuous grain-receiving system includes a large grain tank, a screw lifting machine, a transport trailer and a control unit; the screw lifting machine and the combined harvester are separated; proximity switches are arranged on a left position, a right position, an upper position and a lower position of a grain outlet of the large grain tank; when the grain outlet aligns the screw lifting machine, an on-position signal is given; the control unit is provided with a button which can open or close a granary door; signals of the proximity switches can be acquired through photoelectric isolation; a control alarm light can be output through photoelectric isolation, PMW impulse wave is generated to control forward rotation and inverse rotation of a direct current speed reduction motor, and then the granary door can be opened or closed electrically. The screw lifting machine can perform continuous grain-receiving work on a plurality of harvesters alternatively; and grain-receiving workers and removers are not needed during grain receiving, and then the labor intensity can be remarkably decreased, and the harvesting efficiency of rice can be improved.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a grain receiving electromechanical system of a harvester. Background technique [0002] Due to the consideration that the rice harvester may be trapped when working in the paddy field, the crawler combine harvesters in my country generally adopt the method of receiving grain in grain bags: a full-time grain receiving worker sits at the grain outlet (port A and port B) Next to the mouth), whenever a bag of rice (about 30-40Kg) is full, the grain collector closes the grain outlet (set as A mouth), binds the mouth of the full A bag, and then opens the B bag mouth, Open the B grain outlet and push the A bag down the harvester to reduce the load on the harvester. After that, the A and B grain outlets will be used in turn until the work is completed; there is another porter who needs to remove the bags thrown in the field. Grain bags are dragged to the edge of the field and loaded onto transpo...

Problems solved by technology

[0004] In order to overcome the large labor intensity problem still existing in the large grain box structure of the existing crawler harvester, the present invention provides a continuous grain harvesting system for the harvester, which not only does not require a grain picker, but also does not need a bag mover , the rice can be directly transported from the harvester to the transport vehicle parked on the machine-plowing road, the work intensity is greatly reduced, and the labor efficiency can be significantly improved
