Description

Technical Field

[0001] This invention belongs to the field of plant protection technology, and specifically relates to an electrostatic spraying device. Background Technology

[0002] Electrostatic spraying is a technology that uses an electrostatic field to disperse liquids into small droplets, and it is widely used in plant protection. Its working principle involves creating an electrostatic field between the nozzle and the crop using high-voltage static electricity. When the pesticide solution passes through the nozzle, it generates high-voltage static electricity, which sprays out statically charged droplets. These droplets move directionally under the influence of the electrostatic field, allowing them to adhere evenly to all parts of the plant, including the front and back of leaves and branches, thereby improving pesticide utilization.

[0003] Currently, Chinese invention patent CN113785814B discloses an electrostatic spraying device. However, in existing electrostatic spraying devices, during prolonged spraying, a large amount of pesticide solution is pre-mixed in the tank, and this solution cannot be sprayed out quickly. Therefore, the pesticide inside tends to precipitate in the water, resulting in uneven mixing of pesticide and water, thus leading to poor spraying effect and reduced efficacy. Furthermore, existing electrostatic spraying devices have a limited spraying range, making large-area spraying cumbersome and time-consuming, failing to meet practical application needs. Summary of the Invention

[0004] The purpose of this invention is to provide an electrostatic spraying device, which has the advantages of avoiding pesticide precipitation during long-term spraying and enabling large-area spraying of pesticide solution, allowing the pesticide solution to be mixed and sprayed simultaneously.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an electrostatic spraying device, including a support frame plate, a mixing tank and a fixed base are respectively bolted to the two sides of the top of the support frame plate, a dosing tank is bolted to the top of the fixed base, two drug delivery pipes are symmetrically installed on the side of the mixing tank away from the dosing tank, and an atomizing nozzle is fixedly connected to the ends of the two drug delivery pipes that are far apart from each other. The mixing tank and the dosing tank are respectively equipped with a mixing mechanism and a spraying mechanism that cooperate with the atomizing nozzle.

[0006] The above technical solution utilizes a drive motor to rotate the first mixing rod axially around the center of a rotating cylinder, stirring the pesticide solution. Simultaneously, the first mixing rod's axial rotation drives the second mixing rod to rotate radially around the first, further agitating the solution. This effectively prevents pesticide sedimentation during prolonged spraying and improves the efficiency of pesticide mixing with water, facilitating initial preparation. The drive motor, via a transmission belt, synchronously drives the rotating rod, creating a vacuum that draws the mixed pesticide solution from the mixing tank into the suction pipe. The solution is then fed into the atomizing nozzle for electrostatic spraying. This allows for wide-area spraying, enabling simultaneous mixing and spraying. Pesticide flows into the mixing tank through a connecting pipe, mixing with water to form a pesticide solution. The rotating nozzle controls the connection and closure of the second and first discharge orifices. This allows for intermittent inflow of pesticides, preventing uneven mixing from a single pour and further improving the uniformity of the pesticide solution after mixing with water.

[0007] The invention is further configured such that: the mixing mechanism includes a drive motor bolted to one side of the fixed base; the output end of the drive motor is bolted to a first bevel gear rotatably connected to the fixed base; a rotating cylinder rod is rotatably connected inside the mixing tank; a second bevel gear meshing with the first bevel gear is bolted to the end of the rotating cylinder rod near the first bevel gear; four first mixing rods are symmetrically rotatably connected to the surface of the rotating cylinder rod; a second mixing rod is bolted to the end of the first mixing rod away from the rotating cylinder rod; a fixed rod is rotatably connected inside the rotating cylinder rod; the end of the fixed rod away from the rotating cylinder rod is bolted to the inside of the mixing tank; a third bevel gear rotatably connected to the rotating cylinder rod is bolted to the end of the first mixing rod near the rotating cylinder rod; and a fourth bevel gear meshing with the third bevel gear is fixedly sleeved on the surface of the fixed rod.

[0008] By adopting the above technical solution, the precipitation of pesticides during long-term spraying can be effectively avoided, and the mixing of pesticides in the early stage can also be facilitated.

[0009] The invention is further configured such that: the spraying mechanism includes a fixed column bolted to the inside of the dosing tank; a rotating rod is rotatably connected inside the fixed column; a transmission belt is sleeved on both the end of the rotating rod near the drive motor and the output end of the drive motor via a pulley; a suction pipe groove is opened inside the fixed column; the end of the delivery pipe near the dosing tank communicates with the inside of the suction pipe groove; pump impellers, which cooperate with the delivery pipe and the suction pipe groove respectively, are fixedly sleeved on both ends of the rotating rod; a connecting pipe is fixedly connected between the dosing tank and the mixing tank; a suction pipe communicating with the inside of the suction pipe groove is bolted to the bottom of the fixed column; the end of the suction pipe away from the fixed column passes through the connecting pipe and is fixedly connected to the inside of the mixing tank.

[0010] By adopting the above technical solution, large-scale spraying of the liquid medicine can be achieved, allowing the liquid medicine to be mixed and sprayed simultaneously, thereby improving process efficiency.

[0011] The present invention is further configured such that: a rotating pipe head is rotatably sleeved at the end of the connecting pipe away from the dosing tank; a second disc gear is fixedly sleeved on the surface of the rotating pipe head; a first disc gear meshing with the second disc gear is fixedly sleeved on the surface of the rotating cylinder near the end of the rotating pipe head; a first dispensing hole is opened at the end of the connecting pipe away from the dosing tank; and a second dispensing hole cooperating with the first dispensing hole is opened at the end of the rotating pipe head away from the dosing tank.

[0012] By adopting the above technical solution, the pesticide can be poured in intermittently, preventing uneven mixing caused by pouring the pesticide in at once, and further improving the uniformity of the pesticide solution after mixing with water.

[0013] The present invention is further configured such that: an electrostatic generator is bolted to one end of the fixed base away from the support frame plate, and an electrostatic nozzle is bolted to one end of the atomizing nozzle away from the drug delivery pipeline; both ends of the electrostatic generator and the top of the electrostatic nozzle are fixedly connected with connecting wires, and the electrostatic generator is electrically connected to the electrostatic nozzle through the connecting wires.

[0014] Using the above technical solution, the liquid medicine is introduced into the atomizing nozzle through the medicine delivery pipeline, so that the liquid medicine is atomized. Then, by turning on the electrostatic generator, a high-voltage electrostatic field is generated inside the electrostatic nozzle, which then sprays out liquid medicine droplets with static charge. At the same time, the liquid medicine droplets move in a direction under the action of the electrostatic field, so as to achieve uniform spraying.

[0015] The invention is further configured such that: a reinforcing frame plate is welded to the top of the support frame plate and snaps onto the mixing tank; and support arms are bolted to both sides of the surface of the mixing tank and fixedly sleeved onto the drug delivery pipeline.

[0016] The above technical solution is used to support the mixing tank and the delivery pipeline, thereby improving the stability of the electrostatic spraying device during large-area spraying.

[0017] The present invention is further configured such that the top of both the mixing tank and the dosing tank are threadedly connected with a movable dosing cover.

[0018] By adopting the above technical solution, appropriate amounts of clean water and pesticides are added to the mixing tank and the dosing tank respectively by opening the inside of the dosing cover. At the same time, closing the dosing cover can prevent dust and impurities from falling into the interior.

[0019] The invention is further configured such that: each of the four corners of the bottom of the support frame plate is rotatably connected to a rolling element, and a traction plate is bolted to the end of the fixed base away from the mixing tank.

[0020] By adopting the above technical solution, the electrostatic spraying device is installed at the rear of agricultural machinery using a traction plate, so that the agricultural machinery can pull the electrostatic spraying device forward, thereby enabling the electrostatic spraying device to move and spray pesticide.

[0021] The present invention is further configured such that a filter screen is fixedly sleeved at the end of the electrostatic nozzle away from the atomizing nozzle.

[0022] The above technical solution prevents dust and impurities from entering the interior and avoids clogging of the nozzles.

[0023] The invention is further configured such that: a waterproof baffle is bolted to the inside of the mixing tank, and a sealing ring is fixedly fitted onto the surface of the rotating pipe head and the connecting pipe.

[0024] By adopting the above technical solution, the sealing performance is improved, the water source is isolated, and the impact on gear meshing is prevented.

[0025] In summary, the present invention has the following beneficial effects: 1. A drive motor drives the first mixing rod to rotate axially around the center of the rotating cylinder to stir the pesticide solution. Simultaneously, during the axial rotation of the first mixing rod, the second mixing rod rotates radially around the first mixing rod to further agitate the pesticide solution. This not only effectively prevents pesticide sedimentation during prolonged spraying but also improves the efficiency of mixing pesticides with water, facilitating initial pesticide preparation and mixing. 2. The drive motor synchronously drives the rotating rod via a transmission belt, creating a vacuum inside the mixing tank. This vacuum draws the mixed medicine solution from the mixing tank into the suction pipe through the suction pipe. The solution is then fed into the atomizing nozzle via the delivery pipe for electrostatic spraying. This allows for wide-area spraying of the medicine solution, enabling simultaneous mixing and spraying. 3. The pesticide flows into the mixing tank through the connecting pipe, where it mixes with water to form a pesticide solution. By rotating the pipe head on the surface of the connecting pipe, the second and first pesticide outlets are continuously connected and closed. This allows for intermittent pesticide flow, preventing uneven mixing from a single pour and further improving the uniformity of the pesticide-water mixture. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1: refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5An electrostatic spraying device includes a support frame 1. A mixing tank 2 and a fixed base 3 are respectively bolted to the two sides of the top of the support frame 1. A dosing tank 4 is bolted to the top of the fixed base 3. Two delivery pipes 7 are symmetrically installed on the side of the mixing tank 2 away from the dosing tank 4. Each delivery pipe 7 has an atomizing nozzle 8 fixedly connected to its opposite end. A mixing mechanism 5 and a spraying mechanism 6, which work in conjunction with the atomizing nozzle 8, are respectively installed inside the mixing tank 2 and the dosing tank 4. A drive motor 501 drives a first mixing rod 505 to rotate axially around the center of a rotating cylinder 503 to stir the pesticide solution. Simultaneously, during the axial rotation of the first mixing rod 505, a second mixing rod 506 is driven to rotate radially around the first mixing rod 505 to further agitate the pesticide solution. This not only effectively avoids pesticide sedimentation during prolonged spraying but also improves the efficiency of mixing pesticides with water, facilitating initial preparation and mixing.

[0030] refer to Figure 2 , Figure 3 , Figure 4 The mixing mechanism 5 includes a drive motor 501 bolted to one side of the fixed base 3. The output end of the drive motor 501 is bolted to a first bevel gear 502 rotatably connected to the fixed base 3. A rotating cylinder 503 is rotatably connected inside the mixing tank 2. A second bevel gear 504, meshing with the first bevel gear 502, is bolted to one end of the rotating cylinder 503 near the first bevel gear 502. Four first mixing rods 505 are symmetrically rotatably connected to the surface of the rotating cylinder 503. The ends of the first mixing rods 505 furthest from the rotating cylinder 503 are bolted to... A second mixing rod 506 is connected to the rotating cylinder rod 503, and a fixed rod 507 is rotatably connected inside the rotating cylinder rod 503. The end of the fixed rod 507 away from the rotating cylinder rod 503 is bolted to the inside of the mixing tank 2. A third bevel gear 508 that is rotatably connected to the rotating cylinder rod 503 is bolted to the end of the first mixing rod 505 near the rotating cylinder rod 503. A fourth bevel gear 509 that meshes with the third bevel gear 508 is fixedly sleeved on the surface of the fixed rod 507. This can effectively prevent pesticides from settling when spraying pesticide solution for a long time, and also facilitate the preparation and mixing of pesticides in the early stage.

[0031] refer to Figure 1 , Figure 2 , Figure 5An electrostatic generator 10 is bolted to the end of the fixed base 3 away from the support plate 1, and an electrostatic nozzle 9 is bolted to the end of the atomizing nozzle 8 away from the drug delivery pipe 7. Connecting wires 11 are fixedly connected to both ends of the electrostatic generator 10 and the top of the electrostatic nozzle 9, and the electrostatic generator 10 is electrically connected to the electrostatic nozzle 9 through the connecting wires 11. The drug solution is fed into the atomizing nozzle 8 through the drug delivery pipe 7, causing the solution to atomize. Then, by turning on the electrostatic generator 10, a high-voltage electrostatic field is generated inside the electrostatic nozzle 9, which then sprays out drug droplets carrying static charges. Simultaneously, the drug droplets move in a directional manner under the influence of the electrostatic field, achieving uniform spraying.

[0032] refer to Figure 1 The top of the support frame plate 1 is welded with a reinforcing frame plate 16 that is snapped onto the mixing tank 2. Both sides of the surface of the mixing tank 2 are bolted with support arms 13 that are fixedly connected to the drug delivery pipe 7, which are used to support the mixing tank 2 and the drug delivery pipe 7, thereby improving the stability of the electrostatic spraying device during the process of moving and spraying over a large area.

[0033] refer to Figure 1 , Figure 2 , Figure 4 Both the mixing tank 2 and the dosing tank 4 are threadedly connected to the top of the dosing tank 14. By opening the dosing tank 14, appropriate amounts of water and pesticides are added to the mixing tank 2 and the dosing tank 4 respectively. At the same time, closing the dosing tank 14 can prevent dust and impurities from falling into the interior.

[0034] Brief description of the usage process: First, the drive motor 501 is turned on, driving the first bevel gear 502 to rotate. Then, the rotation of the first bevel gear 502 meshes with the second bevel gear 504, thereby driving the rotating cylinder rod 503 to rotate inside the mixing tank 2. This causes the first mixing rod 505 to shake around the center of the rotating cylinder rod 503, stirring the liquid. Then, during the shaking of the first mixing rod 505, the third bevel gear 508 is driven to mesh with the fourth bevel gear 509, which is fixed on the surface of the fixed rod 507. This causes the first mixing rod 505 to rotate on its own axis during the shaking around the rotating cylinder rod 503, thereby driving the second mixing rod 506 to rotate around the first mixing rod 505, thus agitating the liquid a second time.

[0035] Example 2: refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7An electrostatic spraying device includes a support frame 1. A mixing tank 2 and a fixed base 3 are respectively bolted to the two sides of the top of the support frame 1. A dosing tank 4 is bolted to the top of the fixed base 3. Two delivery pipes 7 are symmetrically installed on the side of the mixing tank 2 away from the dosing tank 4. Each delivery pipe 7 has an atomizing nozzle 8 fixedly connected to its opposite end. A mixing mechanism 5 and a spraying mechanism 6, which work in conjunction with the atomizing nozzle 8, are respectively installed inside the mixing tank 2 and the dosing tank 4. A drive motor 501 synchronously drives a rotating rod 603 via a transmission belt 601, creating a vacuum suction inside the rod 605. This suction draws the mixed liquid inside the mixing tank 2 into the suction pipe 605 through the suction pipe 606. The liquid is then fed into the atomizing nozzle 8 through the delivery pipes 7 for electrostatic spraying. This allows for large-area spraying of the liquid, enabling simultaneous mixing and spraying. The pesticide flows into the mixing tank 2 through the connecting pipe 607, where it mixes with water to form a pesticide solution. The second outlet 611 is continuously connected to and closed with the first outlet 610 by rotating the pipe head 608 on the surface of the connecting pipe 607. This allows for intermittent pesticide flow, preventing uneven mixing from a single pour and further improving the uniformity of the pesticide-water mixture.

[0036] refer to Figure 3 , Figure 4 The spraying mechanism 6 includes a fixed column 602 bolted to the inside of the dosing tank 4. A rotating rod 603 is rotatably connected inside the fixed column 602. The end of the rotating rod 603 near the drive motor 501 and the output end of the drive motor 501 are both connected to a transmission belt 601 via a pulley. A suction pipe groove 605 is opened inside the fixed column 602. The end of the delivery pipe 7 near the dosing tank 4 is connected to the inside of the suction pipe groove 605. Pump impellers 604, which are used in conjunction with the delivery pipe 7 and the suction pipe groove 605, are fixedly sleeved at both ends of the rotating rod 603. A connecting pipe 607 is fixedly connected between the dosing tank 4 and the mixing tank 2. A suction pipe 606, which is connected to the inside of the suction pipe groove 605, is bolted to the bottom of the fixed column 602. The end of the suction pipe 606 away from the fixed column 602 passes through the connecting pipe 607 and is fixedly connected to the inside of the mixing tank 2. It can achieve large-area spraying of the liquid medicine, allowing the liquid medicine to be mixed and sprayed at the same time, thus improving the efficiency of the process.

[0037] refer to Figure 4 , Figure 5 , Figure 7A rotating pipe head 608 is rotatably sleeved at the end of the connecting pipe 607 away from the dosing tank 4. A second disc gear 612 is fixedly sleeved on the surface of the rotating pipe head 608. A first disc gear 609, meshing with the second disc gear 612, is fixedly sleeved on the surface of the rotating cylinder rod 503 near the end of the rotating pipe head 608. A first discharge hole 610 is opened at the end of the connecting pipe 607 away from the dosing tank 4, and a second discharge hole 611, which works in conjunction with the first discharge hole 610, is opened at the end of the rotating pipe head 608 away from the dosing tank 4. This allows for intermittent inflow of pesticides, preventing uneven mixing from a single pour and further improving the uniformity of the pesticide solution after mixing with water.

[0038] refer to Figure 1 The four corners of the bottom of the support frame plate 1 are rotatably connected with rollers 15. The fixed base 3 is bolted with a traction plate 17 at the end away from the mixing tank 2. The electrostatic spraying device is installed behind the agricultural machinery by using the traction plate 17, so that the agricultural machinery can pull the electrostatic spraying device forward, thereby allowing the electrostatic spraying device to move and spray the pesticide.

[0039] refer to Figure 6 The end of the electrostatic nozzle 9 away from the atomizing nozzle 8 is fixedly fitted with a filter screen 12 to prevent dust and impurities from entering the interior and avoid clogging of the nozzle.

[0040] refer to Figure 4 , Figure 7 The mixing tank 2 is fitted with a waterproof baffle 18, and the rotating pipe head 608 and the connecting pipe 607 are both fitted with sealing rings 19 to improve the sealing performance, isolate the water source, and prevent it from affecting the gear meshing.

[0041] Brief description of the usage process: When the drive motor 501 is turned on, it drives the first bevel gear 502 to rotate. The output end of the drive motor 501 drives the rotating rod 603 through the transmission belt 601, thereby causing the rotating rod 603 to drive the pump impeller 604 to rotate inside the fixed column 602, thus pumping the suction pipe 605. The vacuum pressure inside the suction pipe 605 after pumping draws the mixed medicine in the mixing tank 2 into the suction pipe 605 through the suction pipe 606. Then, the medicine is input into the atomizing nozzle 8 through the delivery pipe 7, so that the medicine is atomized. Then, the electrostatic generator 10 is turned on to generate a high-voltage electrostatic field inside the electrostatic nozzle 9, thereby spraying out medicine droplets with static charge. At the same time, the medicine droplets move in a direction under the action of the electrostatic field, so as to achieve uniform spraying. Simultaneously, by adding appropriate amounts of water and pesticides to the mixing tank 2 and the dosing tank 4 respectively, the pesticides can flow into the mixing tank 2 through the connecting pipe 607, where they are mixed with the water to form a pesticide solution. Then, as the drive motor 501 drives the rotating cylinder 503 to rotate, it drives the first disc gear 609 to rotate and mesh with the second disc gear 612, thereby causing the rotating tube head 608 to rotate on the surface of the connecting pipe 607. When the rotating tube head 608 rotates, causing the second outlet 611 to connect with the first outlet 610 at one end of the connecting pipe 607, the pesticide can flow into the mixing tank 2 through the connecting pipe 607 to mix with water. Conversely, when the rotating tube head 608 rotates, causing the second outlet 611 and the first outlet 610 to intersect, the two outlets are no longer connected, preventing the pesticide from flowing into the mixing tank 2 through the connecting pipe 607. This allows for intermittent pesticide flow, further improving the uniformity of the pesticide-water mixture.
