Abstract
Description
Technical Field
[0001] This utility model belongs to the field of drone-based aerial spraying technology, specifically a liquid mixing device for drone-based aerial spraying. Background Technology
[0002] With the development of agricultural mechanization, in order to improve the efficiency of crop spraying, traditional manual spraying methods have been gradually replaced by drone spraying. Current drone spraying involves transporting the drone and pesticide tank to the field in a mother truck, adding pesticide to the drone, and then spraying. During the spraying process, incomplete fertilizer dissolution and the presence of particulate impurities in the fertilizer solution added to the drone's tank can easily clog spray pipes and nozzles. Furthermore, because the pesticide tank is stored in the mother truck for extended periods, sedimentation can occur in the pesticide solution, leading to uneven distribution of fertilizer and compromising the spraying effect. Therefore, it is necessary to design a stirring device that allows for more thorough fertilizer dissolution, preventing particulate fertilizer from clogging nozzles and causing sedimentation. Utility Model Content
[0003] To address the above technical problems, this utility model provides a stirring device that enables fertilizer to dissolve more thoroughly, preventing granular fertilizer from clogging the nozzle and causing sedimentation, thereby solving the problems of incomplete dissolution and easy sedimentation of pesticide solution in the tank during drone-based aerial spraying.
[0004] To solve the above technical problems, the technical solution of this utility model is as follows: a liquid mixing device for drone-based aerial spraying, comprising a mixing tank and a crushing tank. The top of the mixing tank is connected to the crushing tank. Two intermeshing crushing rollers are rotatably connected inside the crushing tank. The mixing tank is divided into a premixing chamber and a mixing chamber from top to bottom. The bottom of the premixing chamber is connected to the mixing chamber. A stirrer is horizontally rotatably connected inside the mixing chamber. The stirrer is driven by a first motor. A discharge port is provided at the bottom of the mixing chamber, and a water outlet pipe is fixedly connected to the bottom side. The other end of the water outlet pipe extends outward through the side wall of the mixing tank. A water pump is installed on the water outlet pipe. A water inlet is provided in the middle of the top of the mixing tank. A gate valve is installed on both the water inlet and the discharge port. A feed inlet is provided at the top of the crushing tank.
[0005] Furthermore, one end of each of the two crushing rollers is fixedly connected to a first gear through the side wall of the crushing box, and a second motor is fixedly connected to the side wall of the crushing box. The output end of the second motor is fixedly connected to a second gear, and the second gear meshes with the first gear for transmission.
[0006] Furthermore, an inclined feeding plate is fixedly connected inside the premixing bin, with one end of the feeding plate inclined downward connected to the outlet of the premixing bin and the other end connected to the outlet of the crushing box.
[0007] Furthermore, the stirrer includes a rotating shaft and stirring blades, the stirring blades being fixedly connected to the rotating shaft, and the stirring blades being designed to gradually shorten from the middle to both sides.
[0008] Furthermore, an arc-shaped plate is provided at the bottom of the crushing chamber, and an inclined plate is provided at the bottom of the mixing chamber.
[0009] Furthermore, a filter screen is fixedly connected to the inlet end of the water outlet pipe.
[0010] This utility model has the following advantages compared with the prior art:
[0011] 1. This utility model features a crushing chamber with two intermeshing crushing rollers rotatably connected inside, which can crush fertilizer, increase the contact area between fertilizer and water, and accelerate fertilizer dissolution. By setting up a premixing chamber, different fertilizers can be mixed after crushing, ensuring more uniform dissolution in the subsequent process. By setting up a stirrer, the water and fertilizer in the mixing chamber can be stirred at all times to prevent fertilizer from settling and to ensure that the fertilizer is completely dissolved, thus avoiding clogging of the nozzle.
[0012] 2. By setting an inclined plate at the bottom of the mixing chamber, this utility model can easily collect insoluble impurities and larger particles in the fertilizer. By setting the mixing blades to gradually shorten from the middle to the sides, it can maximize the mixing in the mixing chamber, so that the fertilizer in the mixing chamber rotates with the mixing blades, accelerating the dissolution of the fertilizer and making it more thorough.

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] like Figures 1 to 4 The illustrated drone-based pesticide spraying device includes a mixing chamber 1 and two crushing chambers 12. The top of the mixing chamber 1 is connected to two crushing chambers 12, which are symmetrically arranged on the top of the mixing chamber 1. To break up clumps of fertilizer and ensure more thorough dissolution, two meshing crushing rollers 14 are rotatably connected inside the crushing chambers 12. The two crushing rollers 14 are equipped with roller teeth that mesh with each other. To ensure more uniform fertilizer mixing, the mixing chamber 1 is divided into a premixing chamber 2 and a mixing chamber 3 from top to bottom. The premixing chamber 2 is conical, and the outlets of the two crushing chambers 12 are contained within it. Waste materials are crushed by the crushing chambers 12, enter the premixing chamber 2, and then fall into the mixing chamber 3. The bottom of the premixing chamber 2 is connected to the mixing chamber 3 to prevent water from entering. Fertilizer produces sediment and can accelerate the complete dissolution of fertilizer. A stirrer 4 is horizontally connected and rotates in the mixing chamber 3. The stirrer 4 is driven by a first motor 5. The first motor 5 is fixedly connected to the side wall of the mixing box 1. The output end of the first motor 5 is fixedly connected to the rotating shaft 41. A discharge port 6 is opened at the bottom of the mixing chamber 3, and a water outlet pipe 9 is fixedly connected to the bottom side. The water outlet pipe 9 is located at the bottom of the mixing box 1. The input end of the water outlet pipe 9 is located at the bottom of the mixing chamber 3. The other end of the water outlet pipe 9 extends outward through the side wall of the mixing box 1. A quick connector is provided on the output end of the water outlet pipe 9 to facilitate the addition of medicine to the drone's medicine tank. A water pump 10 is installed on the water outlet pipe 9. A water inlet 19 is opened in the middle of the top of the mixing box 1. A gate valve 7 is installed on both the water inlet 19 and the discharge port 6. A feed inlet 15 is opened at the top of the crushing box 12.
[0020] In order to enable the two crushing rollers 14 to rotate simultaneously in opposite directions, one end of each crushing roller 14 is fixedly connected to a first gear 16 through the side wall of the crushing box 12. The two identical first gears 16 mesh with each other. A second motor 18 is fixedly connected to the side wall of the crushing box 12. A second gear 17 is fixedly connected to the output end of the second motor 18. The second gear 17 meshes with a first gear 16 that is close to the second gear 17 for transmission.
[0021] In order to premix two different fertilizers after crushing, an inclined feed plate 11 is fixedly connected inside the premixing chamber 2. One end of the feed plate 11 is connected to the outlet of the premixing chamber 2 and the other end is connected to the outlet of the crushing box 12. The two different fertilizers are guided by the feed plate 11 and flow out from the bottom of the premixing chamber 2 at the same time.
[0022] In order to prevent the precipitation of fertilizer solution and promote the complete dissolution of fertilizer, the agitator 4 includes a rotating shaft 41 and a stirring blade 42. The stirring blade 42 is fixedly connected to the rotating shaft 41 and the stirring blade 42 is designed to gradually shorten from the middle to both sides.
[0023] In order to ensure that the crushed fertilizer falls into the premixing chamber 2 below, an arc-shaped plate 13 is installed at the bottom of the crushing box 12, and an inclined plate 8 is installed at the bottom of the mixing chamber 3.
[0024] To prevent undissolved impurities and fertilizer particles from being drawn from the mixing tank 1, which could clog the nozzles after being added to the drone's medicine tank, a filter screen 20 is fixedly connected to the inlet end of the water outlet pipe 9, and a valve is installed on the water outlet pipe 9 to facilitate control of the flow of the medicine.
[0025] It should be noted that in this embodiment, the device is fixed inside the mother car, which is equipped with a mobile power supply sufficient to power the device to complete the aerial spraying. In this embodiment, all the power-consuming devices are connected to the mobile power supply on the mother car.
[0026] The specific working process of this utility model is as follows:
[0027] Before drone-based spraying, different fertilizers and pesticide solutions are added to two crushing chambers 12 in specific proportions. The second motor 18 is then activated, driving the second gear 17 to rotate. The second gear 17 meshes with the first gear 16, causing the crushing roller 14 to rotate and pulverize the fertilizer for subsequent thorough dissolution. Different waste materials enter the premixing chamber 2, are guided by the feed plate 11, and after premixing at the bottom, enter the mixing chamber 3. The first motor 5 is then activated to stir the fertilizer, ensuring uniform mixing. The gate valve 7 on the water inlet 19 is then opened to deliver water into the mixing chamber 3. At this point, the fertilizer and water are mixed. The process begins with dissolving the fertilizer granules. Continuous stirring by stirrer 4 ensures thorough dissolution and prevents sedimentation, which would otherwise lead to uneven distribution of the solution. Once the fertilizer is completely dissolved, water pump 10 is activated, and the outlet pipe 9 is connected to the drone's pesticide tank. The dissolved solution is then pumped into the drone's pesticide tank. After the solution in the mixing tank 1 is used up, the baffle valve 7 on the outlet 6 is opened to clean and collect any remaining fertilizer residue and impurities in the mixing chamber 3. This method of stirring the pesticide solution for drone spraying prevents clogging of the spraying device due to incomplete dissolution of fertilizer granules. Continuous stirring also prevents sedimentation and ensures a more uniform solution.
