An anti-tangle weeder

Abstract

Provided is an anti-binding weeding machine, comprising ejection blocks (46), a limiting plate (49), a ventilating slot (50), an air baffle sheet (10), a power unit (8), an intermediate gear (16), a rotatory elliptic ring (17), a rotatory gear (18), a rotatory ring (15), a first transmission gear (24), a third transmission gear (26), a second transmission gear (25), and a lateral-shift guide rail (14). The use of ejection blocks (46), the limiting plate (49), the ventilating slot (50) and the air baffle sheet (10) between an upper transmission inner rod (11) and a lower transmission inner rod (9) on the weeding machine prevents the power unit (8) from burning out when blades are bound with grass; friction between the ejection blocks (46) and the limiting plate (49) will not cause overheating of said ejection blocks (46) and limiting plate (49); and the use of structures such as the intermediate gear (16), the rotatory elliptic ring (17), the rotatory gear (18), the rotatory ring (15), the first transmission gear (24), the third transmission gear (26), the second transmission gear (25), and the lateral-shift guide rail (14) enables the blades to rotate at different speeds when rotating at different angles, and when the speed is high, the grass can be weeded more quickly, and when the speed is low, the torque is greater, and the blades can weed more powerfully. The weeding machine is simple in structure and good in terms of practical effect.

Description

Technical field [0001] The invention belongs to the technical field of weeders, in particular to an anti-winding weeder. Background technique [0002] 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. [0003] The present invention designs an anti-winding weeder to solve the above problems. Contents of the invention ...

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
