Description

Technical Field

[0001] This invention belongs to the field of vegetable planting technology, specifically relating to an automated pesticide spraying device for facility vegetables. Background Technology

[0002] Facility-based vegetable cultivation refers to a vegetable cultivation model conducted within a controlled environment constructed by artificial facilities. Its main forms include solar greenhouses, multi-span greenhouses, and plastic tunnels. Compared to traditional open-field cultivation, facility-based vegetable production effectively overcomes the limitations of seasons and adverse weather conditions, achieving year-round production and a balanced supply of vegetables, making it an important hallmark of modern agriculture. Its core advantage lies in the precise control of environmental factors such as light, temperature, humidity, and carbon dioxide concentration, creating optimal conditions for vegetable growth and thus significantly increasing yield and quality. Simultaneously, the facility environment forms a physical barrier, significantly reducing the probability and severity of pests and diseases, and lowering pesticide usage, providing a solid foundation for the production of safe, high-quality green vegetables. Therefore, developing the facility-based vegetable industry is of paramount strategic importance for ensuring a stable year-round supply of vegetables, promoting agricultural efficiency, and increasing farmers' income.

[0003] In current greenhouse vegetable cultivation, several problems exist in pesticide spraying. Traditional manual spraying is inefficient, covering only 1-2 acres per day, and the uniformity of pesticide distribution is poor, leading to unstable pest and disease control. Insufficient pesticide dosage in some areas causes pest recurrence, while excessive dosage results in pesticide residue exceeding standards. Although mechanized equipment is gradually being adopted, existing automated spraying devices mostly use fixed spray boom structures, limiting the spraying range (usually no more than 3 meters wide), making it difficult to meet the differentiated spraying needs of different vegetable varieties and growth stages in greenhouses. More importantly, pesticide mixing systems generally have defects: most devices only have simple stirring functions, failing to solve the problem of sedimentation and stratification of high-concentration pesticide solutions. This results in pesticide concentration fluctuations exceeding 15% during spraying, directly affecting the control effect.

[0004] Therefore, there is a need for an automated pesticide spraying device specifically for greenhouse vegetables to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide an automated pesticide spraying device specifically for greenhouse vegetables, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated pesticide spraying device for facility vegetables, comprising a support rod, two symmetrically distributed connecting rods fixed at the top of the support rod, a servo motor fixed at one end of the support rod, a processing cylinder arranged below the support rod, an adjustment component connected to the servo motor for transmission between the processing cylinder and the support rod, a first drive motor fixed at the top of the processing cylinder, a mixing component connected to the first drive motor for transmission inside the processing cylinder, two infusion pumps fixed on the outer wall of the processing cylinder, an infusion pipe connected to the output end of the infusion pump, a nozzle connected to the end of the infusion pipe, and a reversing adjustment component at the bottom of the processing cylinder for adjusting the two nozzles to move in opposite directions.

[0007] It should be noted in the solution that the adjustment component includes a lead screw set inside the support rod, the two ends of the lead screw are rotatably connected to the two ends of the support rod, the output end of the servo motor is fixed to one end of the lead screw, a nut sleeve is threadedly connected to the side of the lead screw, a connecting rod is fixed to the bottom end of the nut sleeve, and the processing cylinder is fixed to the bottom end of the connecting rod.

[0008] It is worth noting that a protruding rod is fixed on the top of the nut sleeve, and a guide groove that is adapted to slide with the protruding rod is provided on the bottom surface of the support rod.

[0009] Furthermore, it should be noted that the mixing assembly includes a shaft rotatably connected to the bottom side wall of the processing cylinder, the output end of the first drive motor is fixed to the top end of the shaft, and a plurality of ring-shaped stirring rods a are fixed on the side of the shaft.

[0010] In a preferred embodiment, the reverse adjustment assembly includes a gear fixed to the bottom end of the shaft, two parallel sliding plates are fixed on the outer wall of the processing cylinder, a guide groove is provided inside the sliding plate along the length of the sliding plate, a connecting seat is fixed to the end of the infusion tube, and a connecting pipe that is slidably adapted to the guide groove is fixed between the connecting seat and the infusion tube.

[0011] In a preferred embodiment, rack plates are fixed on the sides of both connecting pipes, the two rack plates are distributed on both sides of the gear and both rack plates mesh with the gear.

[0012] In a preferred embodiment, a scraper is fixed to the side of the shaft, and there are two scraper rods that are symmetrically distributed. A scraper plate is fixed to the side of the scraper rod along the height direction of the scraper rod.

[0013] In a preferred embodiment, a stirring rod b is fixed to the side of the stirring rod a, and multiple stirring rods b are provided.

[0014] In a preferred embodiment, a plurality of equally spaced protrusions are fixed on the side of the scraper bar.

[0015] In a preferred embodiment, the stirring rod a has a plurality of through holes that are equidistantly distributed on its side.

[0016] Compared with the prior art, the automated pesticide spraying equipment for greenhouse vegetables provided by the present invention has at least the following beneficial effects: 1. The adjustment component drives the processing cylinder to move back and forth in a straight line above the vegetable field, thereby driving the two nozzles at the bottom of the processing cylinder to move back and forth. This allows the nozzles to evenly spray pesticides onto a large area of ​​vegetables, effectively improving spraying efficiency, saving manpower, and greatly reducing the workload of workers. 2. When spraying pesticide solution on vegetables, start the infusion pump. The infusion pump draws the pesticide solution from the processing cylinder and pumps it into the infusion pipe. The infusion pipe then pumps the pesticide solution into the nozzles for spraying. The pesticide solution is sprayed onto the vegetables from the air through two nozzles at the bottom of the processing cylinder. The first drive motor drives the mixing component to continuously stir the pesticide solution stored inside the processing cylinder, preventing the pesticide from settling inside the cylinder. This ensures that the various pesticide components in the pesticide solution inside the processing cylinder always have a good mixing effect, effectively improving the quality of the pesticide solution sprayed from the nozzles, and thus improving the pesticide control effect on vegetables. 3. By adjusting the two nozzles synchronously and in opposite directions using the reversing component, the positions of the two nozzles can be continuously adjusted, causing them to move laterally back and forth to spray the pesticide in a reciprocating oscillating manner. This allows the nozzles to spray over a larger area, effectively increasing the spraying range per unit time and thus improving the overall efficiency of pesticide spraying on vegetables.

[0019] The present invention will be further described below with reference to embodiments.

[0020] Please see Figure 1-9This invention provides an automated pesticide spraying device for facility vegetables, comprising a support rod 8, two symmetrically distributed connecting rods 9 fixed at the top of the support rod 8, a servo motor 7 fixed at one end of the support rod 8, a processing cylinder 5 disposed below the support rod 8, an adjustment assembly 1 connected to the servo motor 7 between the processing cylinder 5 and the support rod 8, a first drive motor 6 fixed at the top of the processing cylinder 5, a mixing assembly 3 connected to the first drive motor 6 disposed inside the processing cylinder 5, and two infusion pumps 13 fixed on the outer wall of the processing cylinder 5. An infusion tube 12 is connected to the output end, and a nozzle 11 is connected to the end of the infusion tube 12. A reversing adjustment component 2 is installed at the bottom of the processing cylinder 5 to drive the two nozzles 11 to move in opposite directions. In use, the servo motor 7 is started, and its output drives the adjustment component 1. This causes the processing cylinder 5 to move back and forth linearly above the vegetable field, thereby causing the two nozzles 11 at the bottom of the processing cylinder 5 to move back and forth. This allows the nozzles 11 to evenly spray pesticides onto a large area of ​​vegetables, effectively improving spraying efficiency. This improves work efficiency, saves manpower, and significantly reduces the workload of workers. When spraying pesticide on vegetables, the infusion pump 13 is activated. The infusion pump 13 draws the pesticide solution from the processing cylinder 5 and pumps it into the infusion pipe 12. The infusion pipe 12 then pumps the pesticide solution into the nozzle 11 for spraying. The pesticide solution is sprayed onto the vegetables from the air through the two nozzles 11 at the bottom of the processing cylinder 5. The first drive motor 6 drives the mixing component 3 to continuously stir the pesticide solution stored inside the processing cylinder 5, preventing the pesticide from accumulating inside the processing cylinder 5, and ensuring that the pesticide solution inside the processing cylinder 5 is evenly mixed. The various drug components always have a good mixing effect, which effectively improves the quality of the liquid sprayed by the nozzle 11, thereby improving the control effect of pesticide spraying on vegetables. At the same time, the mixing component 3 drives the reversing component 2 to work. The reversing component 2 adjusts the two nozzles 11 to move synchronously in opposite directions, thereby continuously adjusting the position of the two nozzles 11. This causes the two nozzles 11 to move laterally back and forth to form a reciprocating oscillating spraying of the liquid, thereby enabling the nozzles 11 to spray over a larger area, effectively increasing the spraying range of the liquid per unit time, and thus effectively improving the overall efficiency of pesticide spraying on vegetables.

[0021] Further as Figure 1 , Figure 3 and Figure 5As shown, it is worth noting that the adjustment component 1 includes a lead screw 105 installed inside the support rod 8. The two ends of the lead screw 105 are rotatably connected to the two ends of the support rod 8. The output end of the servo motor 7 is fixed to one end of the lead screw 105. A nut sleeve 101 is threadedly connected to the side of the lead screw 105. A connecting rod 102 is fixed to the bottom end of the nut sleeve 101. The processing cylinder 5 is fixed to the bottom end of the connecting rod 102. In actual operation, the servo motor 7 is started, and the output end of the servo motor 7 drives the lead screw 105 to rotate back and forth. This causes the lead screw 105 to move the nut sleeve 101 back and forth linearly. This, in turn, causes the processing cylinder 5 to move back and forth linearly above the vegetable field through the nut sleeve 101 and the connecting rod 102. This causes the two nozzles 11 at the bottom of the processing cylinder 5 to move back and forth, allowing the nozzles 11 to spray pesticides evenly over a large area of ​​vegetables, effectively improving spraying efficiency, saving manpower, and greatly reducing the workload of workers.

[0022] Further as Figure 3 , Figure 5 and Figure 6 As shown, it is worth noting that a protruding rod 103 is fixed on the top of the nut sleeve 101, and a guide groove that slides and adapts to the protruding rod 103 is provided on the bottom surface of the support rod 8. In actual operation, the movement of the nut sleeve 101 is guided and limited by the cooperation of the protruding rod 103 and the guide groove, thereby improving the stability of the movement adjustment of the processing cylinder 5.

[0023] Further as Figure 8 and Figure 9 As shown, it is worth noting that the mixing assembly 3 includes a shaft 301 rotatably connected to the bottom side wall of the processing cylinder 5. The output end of the first drive motor 6 is fixed to the top end of the shaft 301, and multiple ring-shaped stirring rods a302 are fixed on the side of the shaft 301. In actual operation, the output end of the first drive motor 6 drives the shaft 301 to rotate, thereby driving the multiple stirring rods a302 to continuously stir the liquid medicine stored inside the processing cylinder 5. This prevents the accumulation of drug residues in the liquid medicine inside the processing cylinder 5, ensuring that the various drug components in the liquid medicine inside the processing cylinder 5 always have a good mixing effect, effectively improving the quality of the liquid medicine sprayed by the nozzle 11, and thus improving the prevention and control effect of spraying pesticides on vegetables.

[0024] Further as Figure 5 , Figure 6 and Figure 7As shown, it is worth noting that the reversing assembly 2 includes a gear 205 fixed to the bottom end of the shaft 301. Two parallel sliding plates 201 are fixed to the outer wall of the processing cylinder 5. A guide groove 202 is provided inside each sliding plate 201 along its length. A connecting seat 10 is fixed to the end of the infusion tube 12. A connecting pipe 204, which slides and adapts to the guide groove 202, is fixed between the connecting seat 10 and the infusion tube 12. A rack plate 203 is fixed to the side of each of the two connecting pipes 204. The two rack plates 203 are distributed between the gear 205 and the shaft 301. Both sides and two rack plates 203 are engaged with gears 205. In actual operation, the rotating shaft 301 drives the gears 205 to rotate, thereby driving the two nozzles 11 to move synchronously in opposite directions through the gears 205 and the two rack plates 203. This allows for continuous adjustment of the position of the two nozzles 11, enabling them to move laterally and reciprocate to spray the pesticide in a reciprocating oscillating manner. This allows the nozzles 11 to spray over a larger area, effectively increasing the spraying range per unit time and thus improving the overall efficiency of pesticide spraying on vegetables.

[0025] Further as Figure 9 As shown, it is worth noting that a scraper rod 304 is fixed on the side of the shaft 301. There are two scraper rods 304, and the two scraper rods 304 are symmetrically distributed. A scraper plate 305 is fixed on the side of the scraper rod 304 and arranged along the height direction of the scraper rod 304. In actual operation, the rotating shaft 301 drives the two scraper rods 304 to rotate synchronously, thereby scraping off the raw material adhering to the inner wall of the processing cylinder 5 through the scraper plate 305 to participate in the mixing and improve the overall mixing effect.

[0026] This solution has the following working process: The servo motor 7 is started, and its output drives the lead screw 105 to rotate reciprocally in both directions. This, in turn, drives the nut sleeve 101 to move linearly back and forth. The nut sleeve 101 and connecting rod 102 then drive the processing cylinder 5 to move linearly back and forth above the vegetable field. This causes the two nozzles 11 at the bottom of the processing cylinder 5 to move reciprocally, allowing the nozzles 11 to evenly spray pesticides onto a large area of ​​vegetables. The output of the first drive motor 6 drives the shaft 301 to rotate, which in turn drives multiple stirring rods a302 to continuously stir the pesticide solution stored inside the processing cylinder 5, avoiding... The drug deposition in the liquid inside the processing cylinder 5 ensures that the various drug components in the liquid inside the processing cylinder 5 always have a good mixing effect. The rotating shaft 301 drives the two scraper rods 304 to rotate synchronously, thereby scraping off the raw materials adhering to the inner wall of the processing cylinder 5 through the scraper plate 305 to participate in the stirring and mixing. The rotating shaft 301 drives the gear 205 to rotate, thereby driving the two nozzles 11 to move synchronously in opposite directions through the cooperation of the gear 205 and the two rack plates 203. This allows for continuous adjustment of the position of the two nozzles 11, so that the two nozzles 11 move laterally back and forth to form a back and forth oscillating spray of the liquid, thereby achieving a larger spraying area by the nozzles 11.

[0027] Further as Figure 9 As shown, it is worth noting that a stirring rod b303 is fixed on the side of the stirring rod a302, and multiple stirring rods b303 are provided. In actual operation, the stirring rods b303 are used to assist in stirring the liquid inside the processing cylinder 5, thereby further improving the mixing effect of the liquid inside the processing cylinder 5.

[0028] Further as Figure 9 As shown, it is worth noting that multiple convex rods are fixed on the side of the scraper rod 304 and are distributed at equal intervals, and multiple through holes are opened on the side of the stirring rod a302. In actual operation, the multiple convex rods are used to further assist stirring.

[0029] In summary: By using the adjusting component 1 to drive the processing cylinder 5 to move back and forth linearly above the vegetable field, the two nozzles 11 at the bottom of the processing cylinder 5 will also move back and forth, allowing the nozzles 11 to evenly spray pesticides onto a large area of ​​vegetables, effectively improving spraying efficiency, saving manpower, and greatly reducing the workload of workers. When spraying pesticides on vegetables, the infusion pump 13 is activated. The infusion pump 13 draws pesticide from the processing cylinder 5 and pumps it into the infusion pipe 12, which then pumps the pesticide into the nozzles 11 for spraying. The pesticide is then sprayed onto the vegetables from the air through the two nozzles 11 at the bottom of the processing cylinder 5. The first drive motor 6 drives the mixing component 3 to adjust the mixing of the processing cylinder... The internally stored pesticide solution is continuously stirred to prevent pesticide residue buildup inside the processing cylinder 5, ensuring that all pesticide components in the solution maintain a good mixing effect. This effectively improves the quality of the pesticide solution sprayed from the nozzle 11, thereby enhancing the pesticide control effect on vegetables. Simultaneously, the mixing component 3 drives the reversing component 2 to operate. The reversing component 2 adjusts the two nozzles 11 to move synchronously in opposite directions, continuously adjusting their positions. This allows the two nozzles 11 to move laterally back and forth, forming a reciprocating oscillating spray pattern, thus enabling the nozzles 11 to spray over a wider area. This effectively increases the spray range per unit time, thereby improving the overall efficiency of pesticide spraying on vegetables.

[0030] The drive motor and servo motor can be purchased from the market. The drive motor and servo motor are equipped with power supplies. This is a mature technology in the field and has been fully disclosed. Therefore, it will not be repeated in the specification.
