Combined Control Structure of Combine Harvester Chassis Lifting and Ridge Breaker Lifting

Abstract

The invention discloses a combined control structure for the lifting of the combine harvester chassis and the lifting of the ridge breaker, which includes an electrical control module and two sets of symmetrically arranged independent assemblies. The electrical control module includes a control panel, a limit switch, an electric control module, The ridge breaker solenoid valve connected to the ridge breaker cylinder, the crawler lifting solenoid valve connected to the chassis lifting cylinder, the control panel is installed in the cab of the harvester; the electronic control module recognizes the operation instructions input by the control panel, And send control instructions to the ridge breaker electromagnetic valve and the track lifting electromagnetic valve; the limit switch is installed on the front mounting seat of the upper platform, the limit switch is connected with the electric control module and sends the feedback signal to the electric control module . In the present invention, the joint control of the hydraulic solenoid valve, the controller and the electrical components is used to realize the lifting of the ridge breaker and the lifting of the lifting chassis, and at the same time avoid any form of failure caused by contact between the ridge breaker and the crawler belt and misoperation. The structure is simple and the operation is simple. convenient.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a combined control structure for the lifting of the chassis of a combine harvester and the lifting of a ridge breaker. Background technique [0002] With the improvement of the technology of domestic combine harvesters, for the areas with less mud feet and the areas where the crawler sags deeply when the harvester is operating, in order to improve the passability of the harvester, it is necessary to increase the height of the lifting chassis from the ground, and some shedding threshing All-in-one machine, because the paving channel is between the two crawlers of the harvester, so the height of the lifting chassis may be increased when paving the sun. Therefore, the chassis lifting technology has been widely used in many combine harvesters. When the harvester is operating Often encounter field ridges, in order to ensure the stability of the harvester passing through...

AI Technical Summary

Problems solved by technology

In the prior art, when a combine harvester with a lifting chassis with a lifting function is equipped with a ridge breaker, when the height of the lifting chassis rises to the highest, the ridge breaker 1 can move at the highest level under the action of the ridge breaker oil cylinder 5. free lift between point M and the lowest point N (such as Figure 1-2 shown), but when the height of the lifting chassis starts to drop or is in a down state, due to the change of the forward inclination angle of the track, the track and the breaker interfere. If the operator of the harvester misoperates the lift control of the breaker cylinder 5 When the driver lowers the height of the lifting chassis from a high position to a low position, if the driver forgets to lower the ridge breaker 1 To N point, also can make ridge breaker 1 contact with crawler belt 10; Above-mentioned two kinds of situations all can cause machine to damage ridge breaker 1 and crawler belt 10 even other parts of harvester when advancing
