Description

Technical Field

[0001] The invention belongs to the technical field of solanacearum wilt prevention and control, and specifically relates to a pesticide spraying device for solanacearum wilt prevention and control. Background Art

[0002] Ralstonia solanacearum is a highly destructive plant pathogen that poses a serious threat to the growth of many crops. Solanaceae crops such as tomatoes, eggplants, peppers, potatoes, and cash crops such as peanuts and tobacco often suffer heavy losses once they are infected by Ralstonia solanacearum. According to statistics, in some high temperature and high humidity areas suitable for the spread of Ralstonia solanacearum, the yield reduction of infected crops can reach 30%-80%, and some serious plots may even have no harvest, causing huge losses to the agricultural economy. Due to its strong survival ability, Ralstonia solanacearum can survive in the soil for several years and spread through various channels such as rainwater, irrigation water, agricultural operations, and insects. Its pathogenic mechanism is complex and it can invade the plant vascular system, reproduce in large numbers and block the ducts, hindering the transport of water and nutrients, causing the plants to wither and die. Therefore, spraying pesticides as a direct and effective prevention and control method is of great significance in the prevention and control of Ralstonia solanacearum.

[0003] Most of the existing pesticide spraying equipment for the prevention and control of bacterial wilt do not have a self-cleaning structure. When the pesticide remains and dries up, it will adhere to the inner wall of the spray head to form dirt. As time goes by, the dirt will become thicker and thicker, reducing the internal space of the spray head and affecting the normal flow path of the pesticide. At the same time, the existing nozzles are easily blocked by tiny impurities in the spray holes. Once blocked, the pesticide cannot be sprayed normally, which can easily lead to uneven spraying of the pesticide and affect the coverage effect of the pesticide on vegetation. Therefore, a pesticide spraying equipment for the prevention and control of bacterial wilt is proposed. Summary of the invention

[0004] In order to solve the problem that most of the above-mentioned background technologies do not have a self-cleaning structure, when the agent remains and dries up, it will adhere to the inner wall of the spray head to form dirt.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention facilitates self-cleaning of the spray head by arranging the cooperation of structures such as the scraper and the elastic nozzle. The scraper is driven to clean the inner wall of the spray head to prevent the residual and scaling of the agent on the inner wall of the spray head, thereby affecting the normal operation of the spray head and reducing the spraying effect. At the same time, it can also avoid the situation that the concentration of the agent sprayed next time is affected. The cleaning can keep the inside of the spray head clean and ensure that the agent can be sprayed smoothly. When tiny impurities block the spray hole, the pressure of the internal agent can make the spray hole slightly expand to squeeze out the impurities, and then the spray hole will automatically return to its original state. Through this dynamic cleaning method, the inside of the spray head can be kept clean and ensure that the agent can be sprayed smoothly, which greatly reduces the risk of spray hole blockage, prevents the situation that the local area cannot be treated with the agent due to blockage, and affects the pest control effect, so that the agent can be sprayed on the vegetation evenly from the spray head.

[0019] The invention facilitates spraying the agent on the middle and upper parts of the vegetation by arranging the coordination of the spiral rod and the cavity and the like. In the process that the agent enters the flat nozzle along the shunt pipe and is sprayed out from the nozzle, the spiral rod rotates to convey air in the direction close to the flat nozzle, so that negative pressure is generated inside the shunt pipe, so that the agent can enter the shunt pipe more easily, and at the same time, pressure can be applied to the passing agent. The additional pressure helps to overcome the resistance of the agent itself and the surface tension at the nozzle and other factors, so as to ensure that the agent can be sprayed out with sufficient speed and force, thereby improving the efficiency and effect of the agent spraying. The cavity and elastic material arranged inside the flat nozzle vibrate with the high-speed flow of the agent, and through vibration, the agent is further dispersed into smaller droplets, so that the agent can form a more uniform spray pattern when spraying, so that it can evenly cover the surface of the plant, improve the control effect of the agent on diseases and insect pests, and reduce the waste of the agent.

[0020] The present invention facilitates comprehensive coverage of vegetation by arranging the coordination of structures such as a spray head and a flat nozzle. By spraying the middle and lower parts of the vegetation with the spray head and spraying the middle and upper parts of the vegetation with the flat nozzle, it can be ensured that the agent covers all parts of the vegetation, effectively killing or inhibiting the living space of pests and diseases at various growth stages, and improving the overall prevention and control effect of pests and diseases.

[0033] A cleaning mechanism 1, the cleaning mechanism 1 is located inside the main mechanism 4;

[0034] Among them, the cleaning mechanism 1 includes an infusion tube 101, a shunt tube 102, a shunt plate 103, a spray head 104, an elastic spray head 105, a scraper 107 and a first bevel gear 108.

[0035] The shape of the spray hole 106 is conical, and the size of the spray hole 106 on the side close to the scraper 107 is larger than the size of the spray hole 106 on the side away from the scraper 107. The shape of the spray head 104 is conical, and a plurality of elastic spray heads 105 are evenly distributed on the side of the spray head 104 away from the infusion tube 101.

[0036] A stirring mechanism 3 is arranged inside the main body mechanism 4, and the stirring mechanism 3 includes a medicine chamber 304.

At the same time, it can also avoid the next spraying The situation that the concentration of the agent is affected occurs. Through this dynamic cleaning method, the inside of the spray head can be kept clean to ensure that the agent can be sprayed out smoothly. When tiny impurities block the spray hole 106, the pressure of the internal agent can make the spray hole 106 slightly expand to squeeze out the impurities, and then the spray hole 106 will automatically return to its original state. Through this dynamic cleaning method, the inside of the spray head can be kept clean to ensure that the agent can be sprayed out smoothly, which greatly reduces the risk of spray hole blockage and prevents the situation that the local area cannot be treated with the agent due to blockage, affecting the effect of disease and insect pest control, so that the agent can be sprayed on the vegetation evenly from the spray head 104.

[0038] like Figures 4 to 9 As shown, a spraying mechanism 2 is arranged on the side of the cleaning mechanism 1, and the spraying mechanism 2 is located on the side of the main mechanism 4. The spraying mechanism 2 includes a flat nozzle 201, and a nozzle 202 is opened on the flat nozzle 201. Two cavities 203 are arranged inside the flat nozzle 201. A spiral rod 204 is rotatably connected to the inner part of the shunt tube 102 near one end of the flat nozzle 201, and the end of the spiral rod 204 away from the flat nozzle 201 is fixedly connected to the second bevel gear 205 through a connecting rod. The two cavities 203 are located on both sides of the nozzle 202. The inner wall of the flat nozzle 201 is made of elastic material, and the side of the flat nozzle 201 away from the nozzle 202 is fixedly connected to the end of the shunt tube 102 away from the infusion tube 101, and the end of the spiral rod 204 away from the second bevel gear 205 penetrates the inner wall of the shunt tube 102 and extends to the inside of the flat nozzle 201.

[0039] The bottom of the stirring paddle 303 is fixedly connected to the first bevel gear 108, the first bevel gear 108 at the bottom of the stirring paddle 303 is meshed with the first bevel gear 108 on the side of the elastic nozzle 105, the second bevel gear 205 is located inside the medicine chamber 304, the side of the cavity 203 is meshed with the second bevel gear 205, and the first bevel gear 108 is rotatably connected to the inner wall of the pressure pump 307.

[0040] The main structure 4 includes a vehicle body 401, a wheel 402 is rotatably connected to the side of the vehicle body 401, a track 403 is slidably sleeved on the wheel 402, a medicine cabin 304 is fixedly connected to the inner wall of the vehicle body 401, a top cover 305 is located above the vehicle body 401, a pressure pump 307 is fixedly connected to the inner wall of the vehicle body 401, an infusion tube 101 and a shunt tube 102 are both fixedly connected to the inner wall of the vehicle body 401, a spray head 104 and a flat spray head 201 are both located on the side of the vehicle body 401, and the spray head 104 is located inside the track 403.

[0041] The above scheme is adopted: by setting the coordination of the spiral rod 204 and the cavity 203 and other structures, it is convenient to spray the medicine on the middle and upper parts of the vegetation. In the process that the medicine enters the flat nozzle 201 along the shunt pipe 102 and is sprayed out from the nozzle 202, the spiral rod 204 rotates to transport air in the direction close to the flat nozzle 201, so that negative pressure is generated inside the shunt pipe 102, so that the medicine can enter the shunt pipe 102 more easily, and at the same time, it can also exert pressure on the passing medicine. The additional pressure helps to overcome the resistance of the medicine itself and the surface tension at the nozzle and other factors, so as to ensure that the medicine can be sprayed out with sufficient speed and force, thereby improving the efficiency and effect of the medicine spraying. The cavity 203 and the elastic material set inside the flat nozzle 201 will vibrate with the high-speed flow of the medicine, and the vibration helps to further disperse the medicine into smaller droplets, so that the medicine can form a more uniform spray pattern when it is sprayed, so that it can evenly cover the surface of the plant, improve the control effect of the medicine on pests and diseases, and reduce the waste of the medicine.

[0042] By setting up the coordination of structures such as the spray head 104 and the flat spray head 201, it is convenient to fully cover the vegetation. The spray head 104 is used to spray the middle and lower parts of the vegetation, and the flat spray head 201 is used to spray the middle and upper parts of the vegetation. This can ensure that the pesticide covers all parts of the vegetation, effectively kill or inhibit the living space of pests and diseases at various growth stages, and improve the overall prevention and control effect of pests and diseases.

[0043] The working principle and use process of the present invention are as follows: first, the prepared medicine for controlling bacterial wilt is injected into the medicine cabin 304 through the feed port 306, and at the same time, the motor 301 is started to rotate the active bevel gear 302, driving the stirring paddle 303 fixedly connected thereto and the first bevel gear 108 at the bottom of the stirring paddle 303 to rotate, thereby driving the first bevel gear 108 fixedly connected to the scraper 107 to rotate, so that the scraper 107 rotates inside the spray head 104 and cleans the inner wall of the spray head 104. By stirring to keep the ingredients uniform, it can be ensured that the medicine always works in the correct proportion and stabilizes the efficacy. At the same time, the rotation of the active bevel gear 302 will drive the second bevel gear 205 meshing therewith to rotate, and the rotation of the second bevel gear 205 will drive the screw rod 204 to rotate;

[0044] At this time, after the medicine in the medicine cabin 304 is pressurized by the pressure pump 307 and transported to the inside of the infusion tube 101, the medicine will be divided into two streams by the diverter plate 103, one of which continues to enter the inside of the spray head 104 along the infusion tube 101, and is sprayed out through the spray hole 106 in the elastic spray head 105 under the action of pressure, spraying the medicine on the middle part of the vegetation and the position close to the root. In this process, the spray hole 106 maintains a stable shape and size. When tiny impurities block the spray hole 106, the pressure of the internal medicine can make the spray hole 106 expand slightly to squeeze out the impurities, and then the spray hole 106 will automatically return to its original state. Through this dynamic cleaning method, the inside of the spray head can be kept clean and the medicine can be sprayed smoothly.

[0045] Another stream of medicine will enter the flat nozzle 201 along the shunt pipe 102 and be sprayed out from the nozzle 202. During this process, the rotation of the spiral rod 204 will transport air in the direction close to the flat nozzle 201, so that negative pressure is generated inside the shunt pipe 102, making it easier for the medicine to enter the shunt pipe 102, and at the same time, it can also exert pressure on the passing medicine. The additional pressure helps to overcome the resistance of the medicine itself and the surface tension at the nozzle and other factors, ensuring that the medicine can be sprayed with sufficient speed and force, thereby improving the efficiency and effect of the medicine spraying. The cavity 203 and elastic material set inside the flat nozzle 201 will vibrate with the high-speed flow of the medicine, and the vibration will help to further disperse the medicine into smaller droplets, so that the medicine can form a more uniform spray pattern when it is sprayed, so that it can evenly cover the surface of the plant.
