Swing arm mower

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a swing arm mower. The swing arm mower comprises a hood, a mowing mechanism, a mechanical arm, an oil cylinder driving mechanism and a gear box, the mowing mechanism is arranged in the hood, the mechanical arm is connected with an upper portion of the hood and drives the hood to integrally move, the oil cylinder driving mechanism is arranged at the upper portion of the hood and drives the hood to open or tilt; and the gear box is arranged on a side edge of the hood and drives the mowing mechanism to move. The novel design structure is adopted, such that the pressure bearing capacity of the force arm is higher, the length of the hood is prolonged, and the mowing efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a swing arm mower. Background technique [0002] The agricultural lawnmower is a vehicle that uses machinery instead of manpower to greatly speed up weed harvesting. Lawn mowers of traditional agricultural lawn mowers usually have the following deficiencies: [0003] 1) Due to its imperfect structural design, the bearing capacity of the moment arm is poor, which makes the width of the mowing operation shorter and the area that can effectively mow the grass is smaller; [0004] 2) The connection method of the mechanical arm and the moon plate used in traditional lawn mowers is usually welded and directly connected, with only one fulcrum, and its structural strength is weak and prone to breakage; [0005] 3) When the moment arm of a traditional lawn mower collides, it does not have any buffer or shock absorbing device, so that the impact force directly acts on the ...

AI Technical Summary

Problems solved by technology

[0003] 1) Due to its imperfect structural design, the bearing capacity of the moment arm is poor, which makes the width of the mowing operation shorter and the area that can effectively mow the grass is smaller;

[0004] 2) The connection method of the mechanical arm and the moon plate used in traditional lawn mowers is usually welded and directly connected, with only one fulcrum, and its structural strength is weak and prone to breakage;

[0005] 3) When the moment arm of a traditional lawn mower collides, it does not have any buffer or shock absorbing device, so that the impact force directly acts on the moment arm, and the moment arm is prone to damage;

[0006] 4) The multi-channel oil circuits used in traditional lawn mowers control the corresponding oil cylinders separately, which consumes a lot of materials and has a demand limit for the output oil circuits of the tractor;

[0007] 5) The traditional lawn mower uses a square tube as the strengthening tube of the lawn mower. Due to the shape limitation of the square tube, it is easier to hang grass, which reduces the mowing efficiency
