Winding preventive weeding machine

Abstract

The invention belongs to the technical field of weeding machines, and in particular relates to a winding preventive weeding machine. The winding preventive weeding machine comprises a propping block, a limiting plate, a ventilating groove, a wind resisting sheet, a power unit, an intermediate gear, a rotating elliptic ring, a rotating gear, a rotating ring, first transmission teeth, third transmission teeth, second transmission teeth and a transverse moving guide rail. According to the wind preventive weeding machine, the propping block, the limiting plate, the ventilating groove and the wind resisting sheet are arranged between an upper inner transmission rod and a lower inner transmission rod and can prevent the power unit from being burnt while blades are wound with grass; the propping block and the limiting plate can be prevented from overheating through the friction between the propping block and the limiting plate; the intermediate gear, the rotating elliptic ring, the rotating gear, the rotating ring, the first transmission teeth, the third transmission teeth, the second transmission teeth, the transverse moving guide rails and other structures are used, so that the blades can rotate at different speeds to reach different angles; the weeding can be quickly carried out in case of high speed; in case of low speed, the torque is large, and the blades can perform weeding with high power; and the winding preventive weeding machine is simple in structure, and good in practical effect.

Description

[0001] Technical field [0002] The invention belongs to the technical field of weeders, in particular to an anti-winding weeder. Background technique [0003] At present, there are various types of weeding machines such as hanging type, rotary type, and reciprocating type in the field of weeding technology. The blade utilizes the high-speed rotation of the engine to greatly increase the output speed, which saves the working time of weeding workers and reduces a lot of human resources. However, there are still many problems, such as the weeder can only operate on a large area of ​​grassland, and cannot remove weeds in some narrow places, and when the blade is entangled by grass, the motor shaft will stop rotating, resulting in motor failure. It is necessary to design a device that can weed in a narrow space and can prevent entanglement while increasing the cost. [0004] The present invention designs an anti-winding weeder to solve the above problems. Contents of the invent...

However, there are still many problems, such as the weeder can only operate on a large area of ​​grassland, and cannot remove weeds in some narrow places, and when the blade is entangled by grass, the motor shaft will stop rotating, resulting in motor failure. It is necessary to design a device that can weed in a narrow space and can prevent entanglement under the condition of increasing costs
