Abstract
Description
Technical Field
[0001] The present application relates to the technical field of protective covers, and in particular to a herbicide blade structure with a protective cover. Background Art
[0002] The weeding device is used to remove weeds on the ground in farmland to prevent weeds from competing with crops for sunlight, nutrients, etc., which affects the growth of crops. The traditional manual weeding method is very inefficient and requires a lot of physical strength. Although the existing mechanical weeding device has greatly improved the weeding efficiency, the weeding blade is often rigidly connected to the rotating shaft. A protective cover is usually installed on the outside of the blade to isolate the blade and protect the user. The existing protective cover generally has a discharge hole to quickly guide the grass removed by the blade. However, when the device is not in use, the blade is usually directly exposed to the outside through the discharge hole, which poses a certain safety hazard. In addition, when the blade is weeding, the removed grass is easily attached to the inner wall of the protective cover, which is not convenient for quick cleaning operations. Therefore, we propose a herbicide blade structure with a protective cover to solve the above-mentioned problems. Utility Model Content

The herbicide blade structure with a protective cover drives the blade 4 to rotate while rotating the rotating shaft 3. The blade 4 weeds the grass by rotating, and the protective cover 2 limits the cleared grass. By rotating the slider 7, the slider 7 slides inside the slide groove 6, thereby driving the scraper 5 to scrape the grass adhered to the inner wall of the protective cover 2, so as to quickly clean the grass inside the protective cover 2. The scraper 5 overlaps with the discharge groove 31 opened on the protective cover 2, and when the device is not in use, the interior of the protective cover 2 is in a semi-sealed state, which reduces safety hazards and improves practicality.

This motor is a well-known device purchased directly from the market by technicians in this field. Here we only use it and do not make any structural and functional improvements to it. We will not go into details here. The motor is provided with a control switch matched with it. The installation position of the control switch is selected according to actual use requirements, which is convenient for the operator to operate and control. The power is output through the bottom end of the motor 12, and then the rotating shaft 3 and the blade 4 are synchronously driven to perform high-speed rotation operations. The high-speed rotating blade 4 contacts the grass body, and then The grass is cleared and discharged through the discharge chute 31 under the limit of the protective cover 2. The slider 7 is rotated to slide inside the slide 6. The slider 7 slides and the scraper 5 is synchronously driven to slide on the inner wall of the protective cover 2. The scraper 5 is constantly in contact with the inner wall of the protective cover 2 to scratch the grass adhered to the inner wall of the protective cover 2.
