Description

rear mounted lawn trimmer

technical field

A rear suspension type mower belongs to the field of animal husbandry institutions.

Background technique

Most of the mowers currently used are driven by road wheels, and the structure is relatively complicated, and the volume is relatively large, which is inconvenient to use, especially for individual herdsmen.

Utility model content

The purpose of the utility model is to provide a small rear-mounted mower which is simple in structure, small in size and convenient for individual herdsmen to use.

The rear suspension mower is composed of a frame, a transmission system, and a grass cutter; the frame is in the shape of a "day", and the front end is equipped with a traction frame and a hydraulic lifting push rod, and the bearing seat is welded on the middle beam of the frame. Bracket; the transmission system is composed of a power input shaft, a universal joint, a shaft, a driving pulley, a driven pulley, a belt, an eccentric wheel and a lawnmower driving connecting rod, and the power input shaft is connected with the driving pulley through a universal joint and a shaft. The bearing seat is fixed on the bearing seat bracket, the driven pulley is connected with the eccentric wheel through the shaft, and the bearing seat is fixed on the middle beam of the frame adjacent to the bearing seat bracket, and the driving and driven pulleys are connected through the belt , the eccentric wheel is equipped with the mower driving link, the other end of the mower driving link is connected with the mower; the main load-bearing rod of the mower is fixed on the middle beam of the frame by the connecting bolt, and the mower It is also welded together with the frame through two steel bars.

When the rear-mounted mower is in use, it only needs to be mounted on the back of the small four-wheel tractor. The specific installation method is: connect the traction frame to the hook behind the tractor; connect the hydraulic cylinder behind the tractor with the hydraulic lifting push rod of the machine; connect the power output shaft behind the tractor with the power input shaft of the machine. Ready to work. The lift of the mower relies on the hydraulic system of the tractor, which is more convenient and labor-saving to operate. The machine is directly driven by the power system of the tractor, so that the structure becomes relatively simple, the volume is reduced, and the manufacture is convenient and the cost is low.
