Trimming control system of greening comprehensive maintenance vehicle and implementation method thereof

Abstract

The invention relates to a trimming control system of a greening comprehensive maintenance vehicle. The system comprises a PLC, a power switch, an emergency stop switch and a proximity switch are connected to the PLC, a handle and an engine are connected to the PLC through a CAN bus, and a 1# big arm hydraulic valve, a 2# large arm hydraulic valve, a 3# big arm hydraulic valve, a trimming device rotary hydraulic valve, a trimming device horizontal moving motor and a cutter rotary motor are connected to the PLC. Accordingly, by means of mutual cooperation of a mechanical structure unit and a trimming control unit, automatic hedge trimming is achieved, the working cycle is shortened, operation is easy, pollution is reduced, the labor cost is effectively lowered, and the level of greening maintenance equipment is improved.

Description

technical field [0001] The invention relates to the technical field of maintenance vehicles, in particular to a pruning control system of a comprehensive greening maintenance vehicle and an implementation method thereof. Background technique [0002] The main function of the greening in the middle belt of the expressway is to beautify the traffic environment and prevent the glare of vehicles at night. Too high or too low greening growth is not conducive to driving safety. Greening and pruning of expressway belts is an important part of expressway greening maintenance, and the improvement of its work efficiency plays an important role in reducing enterprise costs and improving safety factors. [0003] Regular pruning of greenery is an important part of daily maintenance, and the method of greenery pruning is very important to work efficiency and safety. [0004] In the prior art, the trimming is often performed by positioning the pull wire or even completely relying on the e...

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the present invention provides a pruning control system and its implementation method of a comprehensive greening maintenance vehicle. Through the mutual cooperation of the mechanical structure unit and the pruning control unit, the automatic pruning of hedges is realized, the working cycle is shortened, and the operation It is simple, reduces pollution, effectively reduces labor costs, improves the level of greening maintenance equipment, and solves the problem of pruning machines in traditional technology. The broken branches touch the edge of the pruning machine head and cannot enter the negative pressure channel, and the materials are partially accumulated in the box. ;Because the offset generated during the assembly of the box body and the fan is supplemented by welding, it is inconvenient to disassemble and maintain in the later stage; fine materials cannot be fully absorbed into the recovery box, and coarse materials are easy to cause impact on the recovery box; The plate is easy to collide with obstacles on the roadside, causing the bracket to be twisted; the sweeping plate rack is easy to shake along the height direction; the discharge door is easy to automatically loosen; it is difficult to maintain the filter in the cylinder.
