Automatic viaduct green belt trimming device and method

Abstract

The invention discloses an automatic viaduct green belt trimming device and method. The device comprises a guide rail module, a walking module and a shearing module. The guide rail module comprises asupporting rod and a square steel pipe with wavy teeth. The walking module comprises a ball cage gear, a connecting shaft, a chain, a walking motor and a pressing wheel; the shearing module comprisesa shearing motor, a middle wheel, a two-way transmission shaft, helical gears, a blade connecting shaft and blades, the shearing motor is connected with the two-way transmission shaft through the middle wheel, and the helical gears are fixedly connected to the two sides of the two-way transmission shaft; and one end of the blade connecting shaft is connected with the blades, and the other end is paired and connected with the helical gears. The automatic viaduct green belt trimming device is simple in structure, low in manufacturing cost and high in cost performance; overall assembly and disassembly are achieved, and maintenance is convenient; and the existing manual trimming operation can be replaced.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to an automatic trimming device and method for viaduct green belts. Background technique [0002] Due to the particularity of the viaduct, the green belt generally uses flower boxes to hang on both sides, or the top is placed on the anti-collision guardrail, and the planting is mainly carried out through the planting trough flower boxes. Plants in the green belt need to be pruned in time, otherwise the overgrowth of the plants will cover the bridge deck and affect the driving of vehicles on the bridge deck; The city roads are beautiful. At present, the green belt on the viaduct is mainly pruned manually, and the pruning of the branches facing the inner side of the bridge is relatively easy. Generally, manual or vehicle-mounted semi-automatic pruning equipment can be pruned. However, for the pruning of the hanging branches on both sides of the bridge, manual pruning is mainly u...

Problems solved by technology

It can be seen that the working time of workers in this pruning method is limited, and it takes a lot of time to disassemble and move the scaffolding, resulting in low work efficiency and high safety risks

For the pruning of overhanging branches, there are also pruning by mechanical devices, such as Chinese patent application (CN 109479551 A) discloses "a kind of multi-faceted integrated pruning robot and pruning method for high-altitude hedgerows in cities", this device expands through two stages and two stages Folding and trimming the three sides of the hedge, but the mechanical structure of the device is complex, prone to mechanical failure, and the base of the hedge is often blocked by electric poles or signs, etc. In this case, it is difficult to retract the device , time-consuming and inconvenient to operate
