Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic weeding equipment technology, specifically an automatic weeding device that avoids the splashing of broken grass. Background Technology
[0002] In the fields of modern agriculture and garden management, automatic weeding equipment has gradually become the mainstream weeding tool due to its high efficiency and degree of automation. Traditional automatic weeding equipment is usually equipped with a splash guard to prevent broken grass from flying everywhere. However, there is still much room for improvement in its splash prevention effect.
[0003] A search revealed that patent publication number CN216163473U discloses an automatic agricultural weeding machine. This utility model provides an automatic agricultural weeding machine that automatically cuts and quickly clears weeds and is easy to adjust. The automatic agricultural weeding machine includes tires, a shell, a first saw blade, a handle, a steering mechanism, and a cutting mechanism. The steering mechanism is located on the shell, and the handle is located on the upper rear side of the steering mechanism. Tires are mounted on both sides of the steering mechanism, rotating back and forth. The cutting mechanism is mounted on the steering mechanism, and three first saw blades are slidably mounted on the cutting mechanism. This utility model, by incorporating a steering mechanism that works in conjunction with the cutting mechanism, drives the cutting mechanism and the first saw blades to operate. The operation of the cutting mechanism and the first saw blades cuts the weeds on the ground, achieving automatic weeding.
[0004] Existing automatic weeding equipment typically uses splash guards to prevent broken grass from scattering during actual use. However, when broken grass is discharged from the splash guard's outlet, it is easily splashed again due to airflow impact, which not only affects the cleanliness of the working environment but may also cause potential harm to surrounding personnel and equipment. On the other hand, the weeding process generates a large amount of dust, which not only harms the health of operators but also affects the normal operation and service life of the equipment. Existing equipment lacks effective dust reduction measures. In addition, the high-speed cutting blades generate a lot of heat after prolonged operation. If heat cannot be dissipated in time, it will lead to accelerated blade wear, performance degradation, and even equipment failure. Therefore, it is necessary to design an automatic weeding device that avoids the scattering of broken grass. Utility Model Content

It not only effectively avoids the splashing of broken grass, but also reduces the dust generated during the weeding process. It can also cool down the cutting blades on the automatic weeding machine body and extend the service life of the cutting blades.
[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:
[0007] This utility model provides an automatic weeding device to avoid the splashing of broken grass, including an automatic weeding machine body, a splash shield at the bottom of the automatic weeding machine body, broken grass discharge outlets on both sides of the outer wall of the splash shield, and splash baffles at the broken grass discharge outlets, and a spraying component for spraying liquid into the inside of the splash shield is provided on one side of the top of the automatic weeding machine body.

[0033] like Figure 1-8 As shown, an automatic weeding device that avoids the splashing of broken grass includes an automatic weeding machine body 100. The bottom of the automatic weeding machine body 100 is provided with a splash guard 300. Both sides of the outer wall of the splash guard 300 are provided with broken grass discharge outlets 310, and a splash baffle 320 is provided at the broken grass discharge outlets 310. A spraying assembly 200 for spraying liquid into the inside of the splash guard 300 is provided on one side of the top of the automatic weeding machine body 100.
[0034] Connecting shafts 322 are installed on both outer walls of the splash guard 320. The other end of the connecting shaft 322 passes through the bearing on the outer wall of the connecting block 321. A gear 323 is installed on the other end of one of the connecting shafts 322. The connecting block 321 is set on the outer wall of the splash guard 300. Adjustment components 330 for adjusting the tilt angle of the splash guard 320 are provided on both outer walls of the splash guard 300.
[0035] The spray assembly 200 is composed of a pressure storage tank 210, a delivery pipe 220 and a nozzle 230. The bottom end of the spray assembly 200 is provided with a liquid outlet pipe, which is connected to the delivery pipe 220 through a pipe joint. The other end of the delivery pipe 220 passes through the top of the splash shield 300 and extends to the inside of the splash shield 300, and is connected to the nozzle 230 through a pipe joint.
[0036] The pressure storage tank 210 is installed on the top side of the automatic weeder body 100. The top of the automatic weeder body 100 is equipped with an inlet pipe, and both the inlet pipe and the outlet pipe are equipped with solenoid valves. The pressure storage tank 210 stores the liquid to be sprayed. The pressure storage tank 210 has a certain pressure inside. When the solenoid valve on the outlet pipe is opened, the liquid in the pressure storage tank 210 will be transported to the nozzle 230 under the action of pressure and sprayed out from the nozzle 230.
[0037] An L-shaped mounting plate 331 is provided on the adjusting assembly 330. A rotating shaft 336 is installed in the bearing at the top center of the L-shaped mounting plate 331. A rotating adjusting plate 335 is installed at the top of the rotating shaft 336. A movable plate 337 is installed on the circumferential outer wall of the rotating shaft 336.
[0038] A threaded hole is provided at the center of the end wall of the movable plate 337, and an external thread is provided on the circumferential outer wall of the rotating shaft 336. The external thread on the outer wall of the rotating shaft 336 and the threaded hole on the movable plate 337 are connected by a threaded engagement. A slider 334 is installed on one side of the outer wall of the movable plate 337, and the other end of the slider 334 is installed on the slide rail 332. The slider 334 and the slide rail 332 are slidably connected. The slider 334 and the slide rail 332 can play a limiting and guiding role in the movement of the movable plate 337.
[0039] The slide rail 332 is installed on the inner wall of the L-shaped mounting plate 331. One outer wall of the L-shaped mounting plate 331 is connected to the splash guard 300 through the connecting plate 333. A rack plate 338 is installed on the other outer wall of the movable plate 337. The rack plate 338 is meshed with the gear 323. When the operator rotates the rotating adjustment plate 335 forward or backward, it will drive the rotating shaft 336 to rotate forward or backward. When the rotating shaft 336 rotates forward or backward, it will drive the movable plate 337 to move linearly. When the movable plate 337 moves linearly, it will drive the rack plate 338 to move linearly. When the rack plate 338 moves linearly, it will drive the gear 323 to rotate. When the gear 323 rotates, it will drive the splash guard 320 to rotate through the connecting shaft 322, thereby adjusting the tilt angle of the splash guard 320.
[0040] Working Principle: During use, the operator flexibly adjusts the tilt angle of the anti-splash baffle 320 according to actual operational needs. When broken grass is discharged from the broken grass discharge outlet 310, the anti-splash baffle 320 can block the splashing broken grass. By changing the angle of the anti-splash baffle 320, the trajectory and speed of the broken grass during discharge can be effectively changed, significantly reducing secondary splashing caused by airflow impact and other factors, ensuring a clean and safe working environment, preventing broken grass splashing from causing injury to surrounding personnel and equipment, and improving the safety and reliability of equipment use. When the spraying component 200 sprays liquid onto the inside of the anti-splash cover 300, the sprayed liquid can fully combine with the dust in the air inside the anti-splash cover 300, utilizing the liquid... The adsorption effect quickly settles dust particles, significantly reducing the dust content in the working environment, effectively improving the working environment for operators, and reducing the harm of dust to human health. The liquid sprayed by the spray component 200 also acts on the surface of the cut grass, increasing the gravity of the cut grass, thereby further preventing the cut grass from splashing out of the cut grass discharge outlet 310. When the sprayed liquid is sprayed onto the cutting surface of the automatic weeding machine body 100, it can carry away the heat on the cutting blade, effectively controlling the cutting blade temperature, avoiding excessive wear and performance degradation due to excessive temperature, ensuring that the cutting blade is always in good working condition, improving cutting efficiency and accuracy, reducing the frequency of blade replacement, and reducing equipment maintenance costs.
