Description

Technical Field

[0001] This utility model relates to the field of pesticide spraying technology, and more specifically, to a multi-stage filtration mixing box for pesticide spraying. Background Technology

[0002] In the process of broad bean cultivation, scientific and reasonable application of pesticides is a key link in preventing and controlling pests and diseases and ensuring yield. When applying pesticides, it is necessary to prevent the nozzle from being clogged by impurities in the pesticide solution, so that the sprayed solution cannot cover the required spraying range.

[0003] Utility model patent CN218869192U discloses a pesticide sprayer, including a placement plate. A pesticide storage tank is located on the top left side of the placement plate, and a feed inlet is located on the top right side of the storage tank. A water pump is located at the bottom right side of the storage tank. The input end of the water pump is connected to a suction pipe, and the output end is connected to a flexible hose. A movable box is located on the top right side of the placement plate. An electric telescopic rod is located at the bottom of the inner cavity of the movable box. A moving plate is located at the output end of the electric telescopic rod. Fixed rods are located on both sides of the top of the movable plate. The top of the fixed rods extends through and to the top of the movable box, and a spraying head is located at the top of the fixed rods. When the height of the spraying head needs to be adjusted, the electric telescopic rod operates, causing the moving plate to move upward, which in turn causes the fixed rods to move upward, thus adjusting the height of the spraying head.

[0004] Although this sprayer is convenient for mixing the pesticide solution and allows for adjustable spraying height, it still has the following problems in practical use: The sprayer discharges the mixed pesticide solution into the spraying head without filtering it, which may lead to clogging of the nozzle by impurities in the pesticide solution. Furthermore, the sprayer can only spray the very front, resulting in a small coverage area and requiring more spraying cycles. Therefore, we propose a multi-stage filtration mixing tank for this sprayer. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies of unfiltered liquid and small spraying range in the prior art, it is desirable to provide a multi-stage filtration mixing box for a sprayer.

[0006] In a first aspect, this application provides a multi-stage filtration mixing tank for a pesticide sprayer, including a pesticide sprayer base. The top surface of the pesticide sprayer base is provided with a mixing cylinder, a storage tank, and a spray gun connected by a water pipe from front to back. The top of the mixing cylinder is threaded with several dosing boxes. The top surface of the mixing cylinder is also connected to an inlet pipe for connecting to an external water source.

[0015] In this setup, the sealing layer prevents unfiltered liquid from leaking into the spray gun through the gap between the filter box and the storage tank.

[0016] According to the technical solution provided in the embodiments of this application, the number of the plurality of filters is at least three, and the mesh density of the plurality of filters arranged from front to back increases sequentially;

[0017] In this setting, the filtration precision of multiple filters increases sequentially to prevent the mesh from becoming clogged.

[0018] According to the technical solution provided in the embodiments of this application, the number of rows of the nozzles is at least one, the number of nozzles in each row is at least three, and the direction of all the nozzles is not towards the medicine storage tank.

[0019] In this setup, multiple nozzles in various directions ensure that each spray can cover a larger area, improving spraying efficiency.

[0020] According to the technical solution provided in the embodiments of this application, the bottom of the mixing cylinder is connected to a water outlet pipe for sewage discharge, a second water valve is installed on the water outlet pipe, a first water valve is installed on the water pipe connecting the mixing cylinder and the storage tank, and a water pump is fixedly installed on the water pipe connecting the storage tank and the spray gun.

[0021] In this setup, the flow of the pesticide solution is controlled by two water-saving valves, and the spray gun flow rate is controlled by a water pump to determine the spraying distance of the nozzle.

[0022] In summary, this technical solution specifically discloses a multi-stage filtration mixing box for a sprayer, which includes a storage tank, a filter box, a filter screen, a spray gun, and a nozzle. Impurities in the storage tank are filtered by multiple layers of filter screens in the filter box, preventing the nozzle from being clogged by impurities during spraying. Furthermore, the multiple rows of nozzles greatly increase the spraying range of the spray gun and improve spraying efficiency. Attached Figure Description

[0038] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] Please see Figures 1-5 A multi-stage filtration mixing tank for a pesticide sprayer includes a base 1. The top surface of the base 1 is provided with a mixing cylinder 2, a storage tank 3, and a spray gun 4 connected by a water pipe from front to back. The top of the mixing cylinder 2 is threaded with several dosing boxes 21. The top surface of the mixing cylinder 2 is also connected to an inlet pipe 22 for connecting to an external water source. A stirring assembly 5 is installed inside the mixing cylinder 2. The stirring assembly 5 includes a stirring shaft 51 and several stirring blades 52 fixedly installed on the outer wall of the stirring shaft 51. A filter box 33 is slidably connected to the inner wall of the storage tank 3 at the water outlet. Several filter screens 333 are slidably inserted into the filter box 33. Several rows of nozzles 41 are connected and installed on the side wall of the spray gun 4 near the top.

[0041] In this embodiment, as Figure 3 As shown, the stirring assembly 5 also includes a stirring motor 53 installed at the center of the top of the mixing cylinder 2. The top of the stirring shaft 51 passes through the top side wall of the mixing cylinder 2 and is coaxially connected to the output shaft of the stirring motor 53, ensuring that the rotation center of the stirring motor 53 driving the stirring blade 52 is concentric with the mixing cylinder 2, thereby improving the uniformity of stirring and mixing. A limiting sleeve 23 is fixedly installed at the center of the inner side wall of the bottom of the mixing cylinder 2 on the outer side wall of the stirring shaft 51 near the bottom. The limiting sleeve 23 ensures that the stirring blade 52 will not hit the inner side wall of the mixing cylinder 2 and cause damage.

[0042] It should be added that, such as Figure 2 and Figure 4As shown, the top surface of the medicine storage tank 3 is hinged with a door 31. The inner wall of the medicine storage tank 3 near the spray gun 4 has a T-shaped groove 32. The top of the groove 32 is connected to the outside. The filter box 33 near the spray gun 4 has a slider 331 whose size is compatible with the groove 32, so that the filter box 33 can slide in and out through the groove 32 connected to the outside for filtration or disassembly and cleaning.

[0043] Furthermore, such as Figure 5 As shown, the filter box 33 has openings at both the front and rear ends and is connected to the front and rear ends. When the filter box 33 slides to the bottom end, the opening is connected to the water pipe used to connect the medicine storage tank 3 and the spray gun 4. The opening size of the filter box 33 is larger than the outlet size of the medicine storage tank 3. When the filter box 33 is in the lowest position, the medicine can only be discharged into the spray gun 4 through the filter box 33. The side wall of the filter box 33 near the spray gun 4 is covered with a sealing layer 332 of the appropriate size, which seals the gap between the filter box 33 and the inner side wall of the medicine storage tank 3, ensuring that all the medicine is filtered and will not be blocked by impurities in the medicine.

[0044] In this embodiment, as Figure 5 As shown, the number of filters 333 is preferably three, and the mesh density of the filters 333 arranged from front to back increases sequentially to filter impurities in the medicine solution in stages to prevent clogging and improve filtration accuracy.

[0045] Furthermore, such as Figure 2 As shown, the number of columns of nozzles 41 is at least one, and the number of nozzles 41 in each column is preferably five. All nozzles 41 are not oriented towards the storage tank 3. The liquid sprayed by the nozzles 41 can cover the other three directions besides the direction of the storage tank 3, which increases the coverage area each time, reduces the number of times to spray, and greatly improves the efficiency of spraying.

[0046] It is worth mentioning that, such as Figure 2 As shown, the bottom of the mixing cylinder 2 is connected to a water outlet pipe for wastewater discharge. A second water valve 8 is installed on the water outlet pipe to facilitate the discharge of wastewater when the mixing cylinder 2 needs to be cleaned. A first water valve 7 is installed on the water pipe connecting the mixing cylinder 2 and the storage tank 3 to prevent the medicine from entering the storage tank 3 before it is evenly mixed, which would result in insufficient medicine efficacy. A water pump 6 is fixedly installed on the water pipe connecting the storage tank 3 and the spray gun 4. The water pump 6 controls the spraying distance of the nozzle 41, allowing for flexible spraying.

[0047] Finally, it should be noted that the stirring motor 53, water pump 6 and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0048] Working principle: In this embodiment, the multi-stage filtration mixing tank of the sprayer first discharges various agents and external water into the mixing cylinder 2 through the dosing box 21 and the water inlet pipe 22. After the various agents and water are fully mixed by the stirring blade 52, they enter the storage tank 3 through the water pipe. Then, the liquid medicine, after impurities are filtered out by the multi-layer filter screen 333, enters the spray gun 4. Finally, the water pump 6 provides pressure, and the liquid medicine is sprayed out from the nozzle 41.

[0049] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
