[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Example

[0021] Please refer to Figures 1-3 The main purpose of this utility model is to overcome the defects of the existing technology and provide a spraying device for planting selenium-rich fragrant rice. Through optimized structural design, it can achieve efficient recycling of the sprayed liquid, reduce environmental pollution, and improve the convenience and adaptability of spraying operations.

[0022] The spraying device for planting selenium-enriched fragrant rice provided by this utility model mainly consists of a storage tank 2, a first pump body 4, and a spraying main pipe 5. The storage tank 2 is used to store the prepared pesticide solution, and its material can be made of corrosion-resistant high-density polyethylene plastic to ensure that it will not be corroded during long-term storage of the pesticide solution.

[0023] Specifically, the input end of the first pump body 4 can be connected to the inside of the storage tank 2 through a chemically resistant rubber hose. The inner diameter of the rubber hose is adapted according to the flow requirements of the first pump body 4, generally 2-3 cm, to ensure stable extraction of the medicine from the storage tank 2.

[0024] The output end of the first pump body 4 is connected to the main spray pipe 5 via a rigid plastic pipe of the same specification. The rigid plastic pipe has good pressure resistance, can withstand the pressure output by the pump body, and also ensures the stability of the installation position. Several spray branch pipes 8 are connected at equal intervals at the bottom of the main spray pipe 5. The number of spray branch pipes 8 is determined according to the width of the planting area and the spraying requirements, usually 5-10. Atomizing nozzles 9 are installed at the bottom of the spray branch pipes 8. The atomizing nozzles 9 can be made of fine ceramic material, which can evenly atomize the pesticide solution and improve the spraying effect.

[0025] This application includes a liquid-passing section and U-shaped baffles 3 symmetrically arranged on both sides of the main liquid spraying pipe 5. The U-shaped baffles 3 can be made of stainless steel, which has good corrosion resistance and strength. A first liquid receiving groove 300 is provided on the middle side of the inner wall of the U-shaped baffle 3. The inner side of the first liquid receiving groove 300 is inclined downward at 15-30 degrees to facilitate the smooth flow of the collected liquid.

[0026] Multiple liquid-conducting pipes 302 are evenly distributed on the bottom side of the first liquid-receiving tank 300. The liquid-conducting pipes 302 are made of stainless steel and their bottom ends extend into the interior of the second liquid-receiving tank 301. The second liquid-receiving tank 301 is provided on the bottom side of the inner wall of the U-shaped liquid baffle 3. The liquid-conducting part is used to transport the liquid in the second liquid-receiving tank 301 back to the storage tank 2 to realize the recycling of the medicine.

[0027] In some optional embodiments of this application, a first filter screen 31 can be installed on the side of the first liquid receiving tank 300 near the spray branch pipe 8 via a slot. The first filter screen 31 uses a 300-500 mesh stainless steel filter screen to effectively filter out impurities in the liquid. Similarly, a second filter screen 32 can be installed on the top side of the second liquid receiving tank 301 via a slot. The second filter screen 32 has a mesh size of 500-800 mesh, further improving the filtration effect, ensuring the purity of the recovered liquid, and preventing impurities from clogging the pipes and nozzles 9.

[0028] This application also includes a mounting plate 1 that can be installed on a mobile vehicle body. The mounting plate 1 is made of carbon steel with a thickness of 5-8 mm, providing sufficient strength. The liquid storage tank 2 is fixed to the mounting plate 1 with bolts to ensure a secure connection. The first pump body 4 is also fixed to the mounting plate 1 with bolts, and its relative position to the liquid storage tank 2 facilitates pipeline connection. The main spray pipe 5 can be installed at the bottom of the mounting plate 1 via a detachable U-shaped metal fixing bracket. The U-shaped metal fixing bracket is connected to the mounting plate 1 with bolts for easy disassembly and maintenance.

[0029] The liquid conveying section includes a second pump body 7 mounted on the mounting plate 1. The second pump body 7 is fixed to the mounting plate 1 by means of shock-absorbing rubber pads and bolts. The shock-absorbing rubber pads can reduce the vibration of the pump body during operation. The input end of the second pump body 7 is connected to the inside of the liquid storage tank 2 through a corrosion-resistant plastic pipe, and the output end is connected to the inside of the second liquid receiving tank 301 through a bend-resistant liquid conveying hose 71. The inner diameter of the liquid conveying hose 71 is 1-2 cm to ensure smooth liquid delivery.

[0030] In some optional embodiments of this application, a movable component is added for moving the U-shaped baffle 3 away from or towards the spray branch pipe 8. The movable component includes a connecting block 6 welded to the spray main pipe 5. An electric extension rod 61 is bolted to the bottom of the connecting block 6. The output rod of the electric extension rod 61 is threadedly connected to a movable block 62, which is welded to the U-shaped baffle 3. The electric extension rod 61 is a self-locking electric push rod, which can precisely control the position of the U-shaped baffle 3.

[0031] Specifically, in practical applications, the mounting plate 1 of this spraying device is installed on the cargo box of an agricultural tractor and secured with the matching bolts to ensure a firm installation. Based on the planting requirements of selenium-rich fragrant rice, an appropriate amount of herbicide solution is prepared in the storage tank 2. The first pump 4 is started, drawing the herbicide solution from the storage tank 2 through a rubber hose, and then transporting it through a rigid plastic pipe to the main spray pipe 5. The main spray pipe 5 evenly distributes the solution to each spray branch pipe 8, and finally, the atomizing nozzle 9 atomizes the solution and sprays it onto the selenium-rich fragrant rice planting area.

[0032] During spraying, some of the splashed pesticide will come into contact with the U-shaped baffle plate 3. This pesticide flows along the inner wall of the U-shaped baffle plate 3 into the first receiving tank 300. The inclined inner side of the first receiving tank 300 allows the pesticide to flow naturally and into the second receiving tank 301 through the liquid pipe 302. During this process, the first filter plate 31 and the second filter plate 32 filter the pesticide respectively, removing any impurities that may be present.

[0033] When it is necessary to recover the liquid medicine in the second receiving tank 301, the second pump body 7 is started. The second pump body 7 draws the liquid medicine in the second receiving tank 301 back to the storage tank 2 through the liquid flow hose 71, thus completing the recycling of the liquid medicine.

[0034] If different planting row spacing or spraying range requirements are needed, the electric extension rod 61 can be activated. The electric extension rod 61 extends or retracts according to the set instructions, driving the movable block 62 to move, thereby moving the U-shaped liquid baffle 3 away from or closer to the spraying branch pipe 8, adjusting it to a suitable position to meet the requirements of actual spraying operations.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
