Description

Technical Field

[0001] The utility model relates to the technical field of herbicide spraying protection, in particular to a shielding device for spraying herbicides after crop emergence. Background Art

[0002] When crops are planted, weeds will grow between the crops, and people need to spray herbicides to remove the weeds. However, when spraying the herbicides, the herbicides will be sprayed onto the crops, causing the crops to die due to the spraying of the herbicides. Therefore, a shielding device for spraying herbicides after the crops have grown is proposed. Utility Model Content

[0003] In order to solve at least one of the above-mentioned technical shortcomings, the utility model provides a shielding device for spraying herbicides after crop emergence, including a C-shaped bracket, the arc length of the C-shaped bracket is greater than 180° and less than 270°, a slide rail is formed in the middle of the outer wall of the C-shaped bracket, a fixing ring is integrally connected to the middle of the upper surface of the C-shaped bracket, the top of the fixing ring is threadedly connected with a bolt, a control tube integrally connected to the fixing ring is provided on the outside of the C-shaped bracket, a shielding mechanism is provided on the slide rail, a control mechanism is provided inside the control tube, and the end of the control mechanism is connected to the shielding mechanism.

[0004] Furthermore, the shielding mechanism includes a C-shaped slider, the arc length of the C-shaped slider is greater than 180° and less than 270°, a slide groove is formed in the middle of the C-shaped slider, and the slide groove is slidably connected to the slide rail.

[0005] Furthermore, a fan-shaped rubber sheet is provided at the outer edge of the bottom of the C-shaped sliding block, and a spraying hole is opened in the middle of the rubber sheet.

[0006] Furthermore, the control mechanism includes a chain sleeved inside the control tube, the end of the chain is connected to the head of the C-shaped slider, and the other end of the chain is integrally connected to a control rod. Beneficial Effects

[0007] When spraying, the nozzle is installed on the shielding mechanism, the spraying pipe is passed through the fixing ring, the bolts are tightened, and the whole is fixed on the spraying pipe, so that the crop enters the inside of the C-shaped bracket from the opening of the C-shaped bracket, the nozzle is sprayed, and the control mechanism pushes the shielding mechanism to move around the C-shaped bracket, so that the nozzle goes around the periphery of the crop to spray the herbicide on the weeds around the crop.

[0008] When the shielding mechanism is moving, the C-shaped slider is acted upon by a force, causing the C-shaped slider to move on the slide rail, thereby causing the shielding mechanism to move; when spraying, the nozzle is installed on the top of the spraying hole, so that the nozzle is downward, so that the nozzle can only spray the area directly below the spraying hole, and the crop and the sprayed herbicide are isolated by the rubber sheet.

[0009] When controlling the movement of the shielding mechanism, the control rod is pushed to squeeze the chain sleeved inside the control tube out from the end close to the C-shaped slider. The C-shaped slider can move around the slide rail through the push of the chain. When spraying herbicides, the crops can be sprayed 360° while all-round shielding can prevent the herbicide from being sprayed on the crops, and the herbicide can be sprayed on the weeds in the 360° area around the crops.
