Description

Technical Field

[0001] The utility model relates to the technical field of weeding equipment, in particular to a forestry mechanical weeder. Background Art

[0002] In forestry management, weeding is an important task to maintain the growth environment of forests, prevent the spread of pests and diseases, and keep soil healthy.

[0003] In the prior art, after searching, it was found that a Chinese patent disclosed a new type of forestry machinery weeder, and its application number is 201821005207.8. The patent mainly includes a bottom plate, both ends of the bottom of the bottom plate are fixedly connected with connecting rods, the bottom of the connecting rod is movably connected with a wheel axle, and the outside of the wheel axle is fixedly connected with a roller, one end of the top of the bottom plate is fixedly connected with a pushing device, the top of the bottom plate is fixedly connected with a main motor, the output shaft of the main motor is fixedly connected with a rotating shaft, the rotating shaft passes through and extends to the bottom of the bottom plate and is fixedly connected with a fixed disk, the bottom of the bottom plate is fixedly connected with a collection cover located outside the fixed disk, and the surface of the fixed disk is fixedly connected with a cutting knife. Although the above-mentioned new type of forestry machinery weeder uses a fan to collect air with grass smell into the purification box when weeding, the activated carbon in the first filter tube and the second filter tube adsorbs and purifies it, thereby ensuring the air quality of the surrounding environment. However, when the fan collects the air with grass smell into the purification box, some fine grass debris produced by weeding will be transported to the air intake pipe and the fan together with the air under the action of wind, and gradually accumulate inside the air intake pipe, the air inlet of the fan and on the blades, thereby affecting the ventilation capacity of the air intake pipe and the fan. The ventilation capacity of the fan is gradually weakened and may even cause the fan to be completely blocked and unable to work normally, affecting the weeding work. Therefore, those skilled in the art provide a forestry mechanical weeder to solve the problems raised in the above background technology. Utility Model Content
