Fruit tree pruning system based on hydraulic control

Abstract

The invention discloses a fruit tree pruning system based on hydraulic control, solves the problems of fast temperature rise and low production efficiency in the prior art, and has effects of being convenient and flexible to operate and improving pruning efficiency. According to the technical scheme, the system comprises a hydraulic system and a pruning device, wherein the hydraulic system comprises a power unit, an execution unit and a control unit, and the power unit is used for supplying a hydraulic oil source and converting mechanical energy of a power output device into hydraulic energy;the execution unit comprises a motor and multiple hydraulic oil cylinders; the control unit comprises a single-channel stable shunt valve and a multi-way electromagnetic valve, hydraulic oil injectedby the power unit is divided into a constant-current oil passage and a shunting oil passage by the single-channel stable shunt valve, the constant-current oil passage supplies the oil source to the hydraulic oil cylinders, and movement direction and pressure control for the hydraulic oil cylinders is performed through the multi-way electromagnetic valve; the shunting oil passage performs one-way rotating work and overload protection control on a motor through the multi-way electromagnetic valve; and the pruning device is controlled by the execution unit to complete the pruning act.

Description

technical field [0001] The invention relates to the technical field of hydraulic control, in particular to a fruit tree pruning system based on hydraulic control. Background technique [0002] Fruit tree pruning is a very important technical measure in orchard production management. Reasonable pruning plays a vital role in increasing fruit tree yield, prolonging the fruiting period, and improving fruit quality. In recent years, with the establishment of a new type of dwarf wide-row densely planted orchard, it has opened up the way for the mechanized management of orchard production, and equipment such as lawn mowers and sprayers have been widely used. However, fruit tree pruning is still dominated by manual pruning, and the technical level of mechanized pruning equipment is low. Compared with developed countries in Europe and the United States, there is still a big gap. It cannot meet the production needs of large-scale orchards, which seriously restricts the development of ...
