Detailed Description

Example 1

As shown, the present embodiment is primarily directed to the removal of garden weeds. The garden weeding device comprises a vehicle body 2, wherein a driving device 1, a cutting and sucking device 3 and a screening device 4 are mounted on the vehicle body 2.

The driving device 1 comprises a gearbox 12 and a front axle 7 which are driven by a gasoline engine 16, the gearbox 12 is connected with a universal transmission device 9 for transmission, and the universal transmission device 9 transmits power to a differential gear 8 arranged on the front axle 7 to enable a front wheel to rotate; the front wheels are controlled in direction by a steering rod 13. The front wheel is also provided with a damping device 11. The door-type bridge structure adopting the damping device 11 has the advantages that the position of the axle is higher than the central point of the tire, so that the minimum ground clearance can be improved, and the ground can have enough ground clearance.

In addition, the front axle 7 is a flexible frame, the frame can be greatly twisted, tires can also independently move in a large range, only three connecting points are arranged between the frame and the vehicle body, and the balance of the vehicle body can be kept on a rugged road as much as possible. The damping spring on the axle is connected with the vehicle body, and the jolt vibration of the vehicle body ground plate on a rugged road is damped by the damping spring to enable the vehicle body to be stable.

The direction rod 13 is a telescopic direction rod, and a parameter display regulator 15 is installed on the direction rod 13. The gasoline engine 16 drives the front wheel to move forward through transmission of various components, and the direction of the front wheel is controlled through the direction rod 13. In addition, a parameter display regulator 15 is installed on the steering column 13, and the display regulator 15 can control and display system parameters such as an exhaust fan, an exhaust speed, an engine fuel gauge, an engine revolution meter and an engine water temperature gauge.
