A method of controlling a rotary tiller

Abstract

The present invention includes an intelligent control system and method for a rotary cultivator. The system comprises: a reference surface monitoring apparatus, a reference surface monitoring unit, an operation panel, a control unit, a position control rise electrically controlled valve and a position control fall electrically controlled valve, wherein the reference surface monitoring unit and the operation panel are connected with the control unit, and the control unit is connected with the position control rise electrically controlled valve and the position control fall electrically controlled valve. The present invention further comprises the intelligent control method for the rotary cultivator. According to the intelligent control system and method for the rotary cultivator, the tilling state of the rotary cultivator can be controlled, so that the operation is simple, the tilling effect is good, the work efficiency is high, and the labor intensity is low.

Description

technical field [0001] The invention relates to an intelligent control system and method for a rotary tiller. Background technique [0002] At present, the wheeled or crawler-type rotary tillers used in the market are mainly composed of the machine head and the rotary tiller. The two are mechanically connected together, which is a rigid connection. To achieve up and down movement or both up and down movement and left and right tilt movement, the machine head is responsible for providing traction and steering, etc., and the rotary tiller is responsible for cultivating the land. Because the front, back, left, and right sides of the land will be uneven, and the soil foundation will also be different in depth. When the rotary tiller is working, it will undulate or tilt up and down. In order to ensure the level and depth of the cultivated land, the hydraulic system is generally controlled by manual control handles. , carry out up and down movement or left and right movement cont...

AI Technical Summary

Problems solved by technology

Because the front, back, left, and right sides of the land will be uneven, and the soil foundation will also be different in depth. When the rotary tiller is working, it will undulate or tilt up and down. In order to ensure the level and depth of the cultivated land, the hydraulic system is generally controlled by manual control handles. , carry out up and down movement or left and right movement control to adjust the tillage depth of the rotary tiller and the levelness of the fuselage, the operation is cumbersome

Due to human judgment and operational errors, the depth of the land after plowing may be deep or shallow, and it may be uneven.

[0003] In addition, the rotary tiller often needs to be continuously lifted during the cultivation process. For example, the rotary tiller needs to be lifted when reversing, and the rotary tiller needs to be lifted to a certain height when turning. When the rotary tiller is lifted When it is lowered again, the descending depth position also needs to be controlled by people, and the depth of cultivated land is not ideal due to mistakes.

In addition, during the cultivation process, the soil quality of the land is different, and the resistance to the rotary tiller is also different. When the rotary tiller is too deep, especially when the soil is relatively hard, the resistance will increase and the transmission and other parts will be stressed. If it becomes larger, the traction force of the nose is insufficient, which will cause the engine to stall or the tires of the nose to slip. If it is not handled in time, it will even cause damage to the gearbox and seriously affect the service life of the equipment.

[0004] CN104756628A discloses the control system for adjusting the working height of the rotary tiller cutter of the rotary tiller, which cannot identify the plowed ground (not using the plowed ground as a reference), but the plowing depth is based on the plowed ground as a reference, and the plowing cannot be controlled if the plowed ground cannot be identified Depth, unable to meet market demand
