Rotating device capable of connecting double accessory heads

Abstract

The invention discloses a rotating device capable of connecting double accessory heads. The rotating device comprises a moving arm casing, a hydraulic oil cylinder and two chain wheels; two deep groove bearings are fixed at the head end of a chain section casing; a rotating shaft penetrates through the two deep groove bearings; the two chain wheels are symmetrically arranged in the shaft section,between the two deep groove bearings, of the rotating shaft; a chain wheel adjusting shaft is fixed at the tail end of the chain section casing; two chains are correspondingly connected with the two chain wheels on the rotating shaft and the chain adjusting shaft; a chain fixed plate is fixedly overlapped with a position between the two chains; an oil cylinder fixed shaft fixedly penetrates through the chain fixed plate; an oil cylinder positioning shaft penetrates through the two side walls of the tail end of an oil cylinder section casing; the cylinder barrel end of the hydraulic oil cylinder is fixedly connected with the oil cylinder positioning shaft; a piston rod of the hydraulic oil cylinder is fixedly connected with the chain fixed plate through the oil cylinder fixed shaft. The rotating device has the advantages that the rotating shaft drives the chain wheels and the rotating shaft to move through the change of the stroke of the hydraulic oil cylinder, 360-degree rotating of the rotating shaft is realized, a trimming accessory head is mounted on the rotating shaft, and trimming requirements on different angles in the horizontal direction can be met.

Description

technical field [0001] The invention relates to the technical field of moving arms, in particular to a double-attachable head rotating device. Background technique [0002] At present, the pruning and shaping of parks, streets, communities, urban main and secondary arterial green belts, landscape nursery stock modeling, and green plants on expressways mainly rely on workers' operating experience and the use of hand shears or hedge trimmers, among which the most commonly used is the push type. Or backpack pruning machine, the weight of this type of pruning machine is about 5-10 kg, and the operator is always in a serious state during operation, especially when pruning low or high hedges, the operator must also bend down or lift the pruning machine for labor. The strength is high, and the vibration and noise generated by the machine during work are also relatively large. Long-term operation is not conducive to physical and mental health. Moreover, this type of machine complete...

[0002] At present, the pruning and shaping of parks, streets, communities, urban main and secondary arterial green belts, landscape nursery stock modeling, and green plants on expressways mainly rely on workers' operating experience and the use of hand shears or hedge trimmers, among which the most commonly used is the push type. Or backpack pruning machine, the weight of this type of pruning machine is about 5-10 kg, and the operator is always in a serious state during operation, especially when pruning low or high hedges, the operator must also bend down or lift the pruning machine for labor. The strength is high, and the vibration and noise generated by the machine during work are also relatively large. Long-term operation is not conducive to physical and mental health. Moreover, this type of machine completely relies on the operator's pruning skills and sense of responsibility to ensure the smoothness and shape of the pruning. It increases the difficulty of work, and the quality of pruning is difficult to guarantee, especially for the pruning of isolated green belts on both sides of urban roads or high-speed highways that are tens of kilometers or even hundreds of kilometers long. Manual pruning requires a lot of manpower for each maintenance. Material resources, pruning workload is heavy, and there are many vehicles in the work process that may endanger personal safety

At present, among the mechanical arm mechanisms that often appear on the market, the forearm is generally in a horizontal state. A telescopic movement mechanism in the horizontal direction is fixed on the front end of the forearm, and a horizontal displacement arm that can telescopically move on the horizontal plane is installed on the telescopic mechanism. , install a pruning manipulator on the front end of the horizontal shift arm, but these structures are difficult to adapt to the pruning of various shapes, especially the shape requirements with relatively high height requirements, it is difficult to realize, and some have bionic wrist joints to achieve more freedom High degree of rotation, so that the pruning knife can go out of various trajectories in space, and realize the pruning work of various shapes such as spherical, cylindrical, plane and inclined planes. However, the automation degree of the bionic wrist joint is too high, the system precision is high, and the equipment structure is complicated. , the operation is cumbersome, the cost is high, and it is difficult to be widely used in economically underdeveloped areas such as small and medium-sized cities
