Lawn mowing mechanism

Abstract

The invention relates to a lawn mowing mechanism and belongs to the technical field of lawnmowers. The lawn mowing mechanism comprises a frame module, a casing, a brushless motor module, a height adjustment module, a power supply module and a cutter cutting module. The casing is mounted on the frame module, a brushless motor is mounted in the middle of the casing, the cutter cutting module is installed below the brushless motor and connected with the brushless motor module, and the brushless motor module is electrically connected with the power supply module installed at the tail portion of the casing. The height adjustment module includes a rotating handle, a ball screw, a ball base, a supporting bridge plate, a positioning base and a fixing bridge plate; the fixing bridge plate is fixedto the casing, the ball base is mounted on the fixing bridge plate, the supporting bridge plate is arranged above the ball base, the two ends of the supporting bridge plate are fixed to the frame module, the positioning base is mounted above the supporting bridge plate, the ball screw penetrates through the positioning base, the ball base, the fixing bridge plate and the casing, and the upper endof the ball screw is connected with the rotating handle. The lawn mowing mechanism has the advantages of low noise, higher adjustment precision, convenient adjustment and the like.

Description

Technical field [0001] The invention belongs to the technical field of lawnmowers, and particularly relates to a lawn mowing mechanism. Background technique [0002] Automatic lawn mowers are currently relatively mature. Most of the existing automatic lawn mowers are supported by the movement of four wheels. Gasoline or diesel engines are used as power devices. By driving the central shaft to rotate, the shaft makes the blades rotate at high speed. To achieve the effect of cutting the lawn. Although the current lawnmower has a relatively simple structure, it still has the following shortcomings: First, the noise is too large, and the staff is exposed to such noise for a long time, which is harmful to physical and mental health; Second, the height adjustment of the lawn is inconvenient. Most lawnmowers use the integral separation of the frame and the wheel, and the shell and the frame are fixed together. The frame is raised by rotating the buckle through the notch on the wheel to...

Problems solved by technology

Although the structure of the current lawnmower is relatively simple, there are still the following disadvantages: the first is that the noise is too large, and it is unfavorable for the physical and mental health of the staff to be exposed to this noise for a long time; Most lawnmowers use the integral separation of the frame and the wheels to fix the shell and the frame together, and through the notch on the wheel to rotate the buckle, the frame is raised to adjust the shell, that is, the height of the tool from the ground. The height of mowing is inconvenient and the adjustment accuracy is not precise
