[0002] In agricultural production, to ensure high crop yields and provide essential nutrients and control pests and diseases, fertilization and pesticide application are necessary during specific growth cycles. With advancements in sprinkler and drip irrigation technologies, integrated water and fertilizer management has been widely adopted in my country, leading to a corresponding increase in the workload of mixing pesticides and fertilizers. To ensure thorough mixing and dissolution of pesticides and fertilizers before spraying, a power-driven mixing method is needed. This not only reduces manual labor intensity but also avoids the risk of pesticide poisoning from prolonged exposure to pesticides. Summary of the Invention

[0003] This invention aims to solve the problem of water-fertilizer and water-pesticide mixing in the agricultural field. It proposes a water flow mixer that connects the suction pipe and the outlet pipe of the sprayer and connects the water path to the atmosphere. By generating turbulence under pressure, the water promotes the uniform mixing of pesticides or fertilizers with water, thus achieving the mixing of water-fertilizer and water-pesticide. This invention has a simple structure, small size, and low manufacturing cost, and can be applied to water-pesticide mixing during spraying in farmland and fruit tree planting.

The cover plate 2 has a water inlet connection seat 230 and a vent connection seat 220, as well as water channels arranged in positions corresponding to the base 1. The upper cover plate 3 has a first mating hole 31, a second mating hole 32, and a third mating hole 33. The bottom plate 4 is fixed to the bottom of the base 1. The feature is that the center of the internal space of the base 1 has a radial flow channel 15, and the two ends of the radial flow channel 15 have partitions 16. A notch 161 is formed at the center of the upper edge of the partition 16. The partition 16 of the radial flow channel 15 extends radially to form a water channel confluence area 151, which penetrates the transverse hole 11 of the circumferential wall. Arc-shaped flow channels 17 are formed in the inner space of the seat body 1, with the two sides of the water channel confluence area 151 as the starting points. The arc-shaped flow channels 17 are connected to the water channel confluence area 151. A straight riser 120 is formed on the inner wall of the radially opposite side of the arc-shaped flow channel 17. The inner hole of the straight riser 120 is formed with an internal thread 12. The surface plane 181 around the water channel arrangement area of ​​the seat body 1 has a groove 2901 that is matched and positioned with the cover plate 2. The cover plate 2 has a water inlet chamber 28. A water inlet connector 230 extends from the center of the water inlet chamber 28 towards the bottom or in the opposite direction. A water inlet through-hole 23 is formed inside the water inlet connector 23, and the end of the water inlet through-hole 23 has an internal thread. The water inlet chamber 28 is aligned with the radial flow channel 15 of the seat body 1. Baffles 26 are formed at both ends of the water inlet chamber 28. A transverse small hole 261 is formed along the center edge of the baffle 26. The baffle 26 cooperates with the partition plate 16. A water outlet channel 281 extends straight outward from the baffles 26 of the water inlet chamber 28. The concave arc 24 on the outside of the water outlet channel 281 interacts seamlessly with the semi-circular arc 110 inside the transverse hole 11. The water outlet 281 is connected by a seam. On both sides of the water outlet 281, an arc-shaped waterway 27 is made at the corresponding position of the arc-shaped flow channel 17. The center position of the arc-shaped waterway 27 extends to the bottom or in the opposite direction to make a venting connection seat 220. The venting connection seat 220 has a vent hole 22. The opening end of the vent hole 22 has an internal thread. The water channel arrangement area of ​​the cover plate 2 is surrounded by a rib 29 that is positioned to cooperate with the groove 2901 of the seat body 1. During assembly, the rib 29 of the cover plate 2 is inserted into the groove 2901 of the seat body 1 to obtain precise positioning.

After pressurization, it flows from the outlet pipe B through the inlet hole 23 into the radial flow channel 15. Due to the obstruction of the baffle 16, the water can only flow out from the notch 161 and the transverse small hole 261, resulting in a reduction in the cross-sectional area of ​​the water flow channel and an increase in pressure. When the water enters the waterway confluence area 151, the vent hole 22 discharges air. Under its own weight, the water flows out from the waterway confluence area 151 through the water nozzle 5 fitted with the transverse hole 11. The water flow generates turbulence under pressure, promoting the uniform mixing of pesticide and water, thus achieving the purpose of this utility model.

The water inlet chamber 28 is aligned with the radial flow channel 15 of the seat body 1. Baffles 26 are formed at both ends of the water inlet chamber 28.

A water outlet channel 281 extends straight outward from the baffles 26 of the water inlet chamber 28. The concave arc 24 on the outside of the water outlet channel 281 interacts seamlessly with the semi-circular arc 110 inside the transverse hole 11. The water outlet 281 is connected by a seam. On both sides of the water outlet 281, an arc-shaped waterway 27 is made at the corresponding position of the arc-shaped flow channel 17. The center position of the arc-shaped waterway 27 extends to the bottom or in the opposite direction to make a venting connection seat 220. A venting hole 22 is made in the venting connection seat 220. The opening end of the venting hole 22 is made with an internal thread. The water channel arrangement area of ​​the cover plate 2 is surrounded by a rib 29 that is positioned to cooperate with the groove 2901 of the seat body 1. During assembly, the rib 29 of the cover plate 2 is inserted into the groove 2901 of the seat body 1 to achieve precise positioning. The seat body 1 and the cover plate 2 are fixed together with screws, or the seat body 1 and the cover plate 2 are welded together.

[0010] In the assembly of the base body 1 described in this utility model, the upper cover plate 3 is installed on the inner diameter of the upper opening of the base body 1. The first mating hole 31 of the upper cover plate 3 mates with the straight riser 120 of the base body 1, the second mating hole 32 of the upper cover plate 3 mates with the water inlet connection seat 230, and the third mating hole 33 of the upper cover plate 3 mates with the vent connection seat 220. They are fixed together by plastic welding or screws. The bottom plate 4 mates with the bottom section 19 of the base body 1 and is fixed together by screws with screw holes 191, thus completing the entire installation of the machine.

[0011] In one form, the base plate 4 has mesh holes 41 and screw holes.

[0012] In one embodiment, the transverse hole 11 of the seat 1 is provided with an internal thread, which serves to connect with the water tap 5 during use.

[0013] The base 1 described in this utility model is cylindrical with upper and lower edges. The circumferential wall of the base 1 has mesh holes 10, and the internal space of the base 1 has a water channel.

[0014] In one embodiment, the upper and lower edges refer to the technical dimensions that extend radially from the upper opening and bottom position, having a diameter greater than that of the middle part of the base 1, in order to accommodate the installation of the upper cover plate 3 and the bottom plate 4 and ensure product strength.

[0015] The seat 1 has a built-in space with a water channel, which includes all paths through which water and air pass.

[0016] The radial flow channel 15 is located at the center of the built-in space of the seat body 1.

[0017] In one embodiment, the radial flow channel 15 has baffles 16 at both ends, and the baffles 16 have a notch 161 at the center of the upper edge.

[0018] Technicians can understand that the radial flow channel 15 is located in the center of the built-in space of the seat body 1, which helps the equipment to achieve balanced force under the impact of water flow pressure during operation.

[0019] In one embodiment, the radial flow channel 15 serves as the first station for water to enter the equipment, and is separated from the outside by the baffle 16; then the flow is delivered to the outside through the notch 161; therefore, the radial flow channel 15, the baffle 16, and the notch 161 are the key components of this utility model. The radial flow channel 15 is used for water storage inside, the baffle 16 is used for water path separation, and the notch 161 changes the cross-sectional area of ​​the inlet flow.

[0020] Furthermore, the notch 161 in this invention reduces the cross-sectional area of ​​the water inlet flow while increasing the water pressure, causing the water to enter the bucket and generate greater turbulence, thus achieving a thorough mixing of the water and medicine or water and fertilizer. Technicians can verify this by spraying the syringe with and without a needle, as the two are based on the same technical principle.

[0021] In one embodiment, the baffle 16 of the radial flow channel 15 extends radially and has a water channel confluence area 151, which penetrates the transverse hole 11 of the circumferential wall.

[0022] In one form, arc-shaped flow channels 17 are created within the built-in space, with the water confluence area 151 of the inner diameter of the seat body 1 serving as the starting point on both sides.

[0023] In one configuration, the arc-shaped flow channel 17 is connected to the waterway confluence area 151.

[0025] Furthermore, the straight riser 120 is located on the inner wall of the radially opposite side of the arc-shaped flow channel 17.

The circumferential wall at the bottom of the straight riser 120 is provided with an arc-shaped notch 121 for use as a water absorption space.

[0026] In one form, the surface plane 181 around the water channel arrangement area of ​​the base 1 has a groove 2901 that is positioned to cooperate with the cover plate 2.

[0027] In one embodiment, the cover plate 2 is provided with a water inlet connector 230 and a vent connector 220, as well as water passage positions corresponding to the seat body 1.

[0028] In one embodiment, the water inlet connector 230 is located on the upper surface of the cover plate 2, opposite to the water inlet chamber 28. The water inlet connector 230 has a water inlet through hole 23, and the end of the water inlet through hole 23 has an internal thread. The water inlet through hole 23 of the water inlet connector 230 is aligned with the water inlet chamber 28.

[0029] In one embodiment, the vent connector 220 is located on the upper surface of the cover plate 2, opposite to the arc-shaped waterway 27. The vent connector 220 has a vent hole 22 inside, and the opening end of the vent hole 22 has an internal thread.

[0030] In one embodiment, the cover plate 2 is provided with a water inlet chamber 28, and a water inlet connector 230 is formed by extending from the center of the water inlet chamber 28 to the bottom or in the opposite direction.

[0031] In one configuration, the water inlet chamber 28 is arranged in a position that matches the radial flow channel 15 of the base 1.

[0032] In one embodiment, baffles 26 are provided at both ends of the water inlet chamber 28, and a transverse small hole 261 is provided at the center edge of the baffle 26. The baffle 26 cooperates with the partition 16.

[0033] In one form, the transverse small hole 261 and the notch 161 are closely matched, and the two together form a transverse hole, which acts on the path of the radial flow channel 15 or the water inlet 28 to transport water to the outside.

[0034] In one embodiment, the baffle 26 of the water inlet chamber 28 extends outward in a straight direction to form a water outlet 281, and the concave arc 24 on the outside of the water outlet 281 is seamlessly connected to the semi-arc 110 on the inside of the transverse hole 11.

[0035] In one form, arc-shaped waterways 27 are formed at corresponding positions on both sides of the outlet waterway 281 as the starting point, and a ventilated connecting seat 220 is formed by extending from the center position of the arc-shaped waterway 27 to the bottom or in the opposite direction.

[0036] Furthermore, the vent connector 220 has a vent hole 22 inside, and the opening end of the vent hole 22 has an internal thread.

[0037] In one embodiment, the outer straight wall of the cover plate 2 is provided with a concave arc notch 25, which is adjacent to and fitted with the straight riser 120 during installation.

[0038] In one embodiment, the water channel arrangement area of ​​the cover plate 2 is surrounded by raised ribs 29 that are positioned to cooperate with the grooves 2901 of the seat body 1.

[0039] In one embodiment, during assembly, the protruding rib 29 of the cover plate 2 is inserted into the groove 2901 of the base 1 to achieve precise positioning, and the screws are fixed to the screw holes 21 of the cover plate 2 through the screw holes 18 of the base 1 or by welding, thus completing the assembly.

[0040] Technicians should clearly understand that the cooperation between the rib 29 of the cover plate 2 and the groove 2901 of the seat 1 only serves to position the product. There are many equivalent replacement methods known in the art to achieve precise positioning, such as the shape limitation of the pin or the local shape. These replacement methods can achieve the same technical effect without the need for labor.

[0041] Furthermore, ignoring the fit between the rib 29 of the cover plate 2 and the groove 2901 of the seat 1, the product can still be used. However, by applying the rib 29 and the groove 2901 of the seat 1, a higher technical precision in the fit can be obtained, which is unrelated to the product's functional application.

[0042] After the entire machine is assembled, in application, the inner hole of the vertical riser 120 is connected to the water suction pipe A of the sprayer, the water inlet hole 23 is connected to the water outlet pipe B of the sprayer, and the vent hole 22 is connected to the air outlet hose C. When the agitator is placed in the pesticide tank and the sprayer is started, the water in the tank is drawn into the water suction pipe A of the sprayer through the water passage in the inner hole of the vertical riser 120. After being pressurized by the sprayer, it flows into the water inlet hole 23 through the water outlet pipe B and then into the radial flow channel 15. Under the obstruction of the partition 16, the water can only flow out from the notch 161 and the transverse small hole 261, which reduces the cross-sectional area of ​​the water flow channel and increases the pressure. When the water flows into the water channel confluence area 151, the vent hole 22 discharges air outward. Under the action of its own weight, the water flows out from the water channel confluence area 151 through the transverse hole 11. The water flow generates turbulence under pressure, which promotes the uniform mixing of pesticide and water, thus achieving the purpose of this utility model. Attached Figure Description

[0068] The seat 1 has a built-in space with a water channel, which includes all paths through which water and air pass.

[0069] The radial flow channel 15 is located at the center of the built-in space of the seat body 1.

[0070] In one embodiment, the radial flow channel 15 has baffles 16 at both ends, and the baffles 16 have a notch 161 at the center of the upper edge.

[0071] Technicians can understand that the radial flow channel 15 is located in the center of the built-in space of the seat body 1, which helps the equipment to achieve balanced force under the impact of water flow pressure during operation.

[0072] In one embodiment, the radial flow channel 15 serves as the first station for water to enter the equipment, and is separated from the outside by the baffle 16; then the flow is delivered to the outside through the notch 161; therefore, the radial flow channel 15, the baffle 16, and the notch 161 are the key components of this utility model. The radial flow channel 15 is used for water storage inside, the baffle 16 is used for water path separation, and the notch 161 changes the cross-sectional area of ​​the inlet flow.

[0073] Furthermore, the notch 161 in this invention reduces the cross-sectional area of ​​the water inlet flow while increasing the water pressure, causing the water to enter the bucket and generate greater turbulence, thus achieving a thorough mixing of the water and medicine or water and fertilizer. Technicians can verify this by spraying the syringe with and without a needle, as the two are based on the same technical principle.

[0074] In one embodiment, the baffle 16 of the radial flow channel 15 extends radially and has a water channel confluence area 151, which penetrates the transverse hole 11 of the circumferential wall.

[0075] In one form, arc-shaped flow channels 17 are created within the built-in space, with the water confluence area 151 of the inner diameter of the seat body 1 serving as the starting point on both sides.

[0076] In one configuration, the arc-shaped flow channel 17 is connected to the waterway confluence area 151.

[0077] In one form, the radially opposite inner wall of the arcuate flow channel 17 is provided with a straight riser 120, and the inner hole of the straight riser 120 is provided with an internal thread 12.

[0078] Furthermore, the straight riser 120 is located on the inner wall of the radially opposite side of the arc-shaped flow channel 17. The straight riser 120 extends from the upper surface of the seat 1 to the bottom, exceeding the reverse bottom plane 182 of the water channel mating area. The circumferential wall at the bottom of the straight riser 120 is provided with an arc-shaped notch 121 for use as a water absorption space.

[0079] In one form, the surface plane 181 around the water channel arrangement area of ​​the base 1 has a groove 2901 that is positioned to cooperate with the cover plate 2.

[0080] In one embodiment, the cover plate 2 is provided with a water inlet connector 230 and a vent connector 220, as well as water passage positions corresponding to the seat body 1.

[0081] In one embodiment, the water inlet connector 230 is located on the upper surface of the cover plate 2, opposite to the water inlet chamber 28. The water inlet connector 230 has a water inlet through hole 23, and the end of the water inlet through hole 23 has an internal thread. The water inlet through hole 23 of the water inlet connector 230 is aligned with the water inlet chamber 28.

[0082] In one embodiment, the vent connector 220 is located on the upper surface of the cover plate 2, opposite to the arc-shaped waterway 27. The vent connector 220 has a vent hole 22 inside, and the opening end of the vent hole 22 has an internal thread.

[0083] Furthermore, the vent 22 is provided with internal threads for connection and fixation with components.

[0084] In one embodiment, the cover plate 2 is provided with a water inlet chamber 28, and a water inlet connector 230 is formed by extending from the center of the water inlet chamber 28 to the bottom or in the opposite direction.

[0085] In one configuration, the water inlet chamber 28 is arranged in a position that matches the radial flow channel 15 of the base 1.

[0086] In one embodiment, baffles 26 are provided at both ends of the water inlet chamber 28, and a transverse small hole 261 is provided at the center edge of the baffle 26. The baffle 26 cooperates with the partition 16.

[0087] In one form, the transverse small hole 261 and the notch 161 are closely matched, and the two together form a transverse hole, which acts on the path of the radial flow channel 15 or the water inlet 28 to transport water to the outside.

[0088] In one embodiment, the baffle 26 of the water inlet chamber 28 extends outward in a straight direction to form a water outlet 281, and the concave arc 24 on the outside of the water outlet 281 is seamlessly connected to the semi-arc 110 on the inside of the transverse hole 11.

[0089] In one form, arc-shaped waterways 27 are formed at corresponding positions on both sides of the outlet waterway 281 as the starting point, and a ventilated connecting seat 220 is formed by extending from the center position of the arc-shaped waterway 27 to the bottom or in the opposite direction.

[0090] Furthermore, the vent connector 220 has a vent hole 22 inside, and the opening end of the vent hole 22 has an internal thread.

[0091] In one embodiment, the outer straight wall of the cover plate 2 is provided with a concave arc notch 25, which is adjacent to and fitted with the straight riser 120 during installation.

[0092] In one embodiment, the water channel arrangement area of ​​the cover plate 2 is surrounded by raised ribs 29 that are positioned to cooperate with the grooves 2901 of the seat body 1.

[0093] In one embodiment, during assembly, the protruding rib 29 of the cover plate 2 is inserted into the groove 2901 of the base 1 to achieve precise positioning, and the screws are fixed to the screw holes 21 of the cover plate 2 through the screw holes 18 of the base 1 or by welding, thus completing the assembly.

[0094] Technicians should clearly understand that the cooperation between the rib 29 of the cover plate 2 and the groove 2901 of the seat 1 only serves to position the product. There are many equivalent replacement methods known in the art to achieve precise positioning, such as the shape limitation of the pin or the local shape. These replacement methods can achieve the same technical effect without the need for labor.

[0095] Furthermore, ignoring the fit between the rib 29 of the cover plate 2 and the groove 2901 of the seat 1, the product can still be used. However, by applying the rib 29 and the groove 2901 of the seat 1, a higher technical precision in the fit can be obtained, which is unrelated to the product's functional application.

[0096] After the entire machine is assembled, in application, the inner hole of the vertical riser 120 is connected to the water suction pipe A of the sprayer, the water inlet 23 is connected to the water outlet pipe B of the sprayer, and the vent 22 is connected to the air outlet hose C. When the agitator is placed in the pesticide tank and the sprayer is started, the water in the tank is drawn into the water suction pipe A of the sprayer through the water passage inside the vertical riser 120. After being pressurized by the sprayer, it flows from the water outlet pipe B into the water inlet 23 and then into the radial flow channel 15. With the obstruction of plate 16, the water can only flow out from the notch 161 and the transverse small hole 261, which reduces the cross-sectional area of ​​the water flow channel and increases the pressure. When the water flows into the water channel confluence area 151, the vent 22 discharges air outward. Under its own weight, the water flows out from the water channel confluence area 151 through the water nozzle 5 that matches the transverse hole 11. The water flow generates turbulence under pressure, which promotes the uniform mixing of pesticide and water, thus achieving the purpose of this utility model.

[0097] This utility model discloses an agricultural mixer. The mixer connects to the water suction pipe A and water outlet pipe B of a pesticide sprayer and can be placed directly into the pesticide tank for use. It has a large mixing capacity, capable of mixing over two tons of pesticide solution at a time, making it suitable for large-scale pesticide spraying. This water-driven mixer is simple to operate, highly effective, and easily achieves uniform mixing of pesticides and water. It is widely applicable to orchards, farmland, and other agricultural planting areas, and is highly favored by agricultural practitioners.

[0098] Those skilled in the art will understand that appropriate adjustments can be made to the disclosed configuration without departing from the present invention. Therefore, the examples described above are for illustrative purposes only and not for limiting purposes. Those skilled in the art will clearly recognize that minor modifications can be made to the configuration or installation process to achieve the same purpose without significantly altering the above operations. The present invention is limited by the claims.
