Description

Technical Field

[0001] This utility model relates to the field of plant protection machinery technology, specifically a circulating pesticide mixing device for plant protection machinery. Background Technology

[0002] Plant protection drones are indispensable intelligent equipment in modern agriculture, integrating technologies from multiple fields such as aerospace, automatic control, and agricultural plant protection. They use drones or ground machinery equipped with spraying devices to precisely control the amount and coverage of pesticides, increasing efficiency by dozens of times compared to traditional manual operation. They also avoid the health risks of direct contact with pesticides. At the same time, their high-precision positioning and intelligent planning systems can achieve variable-rate application based on terrain and crop growth conditions, reducing pesticide waste and environmental pollution while ensuring healthy crop growth, thus powerfully promoting the development of agricultural production towards high efficiency, greenness, and intelligence.

[0003] In existing technologies, when farmers prepare to carry out pest and disease control operations on a large area of ​​crops in large farmlands, the circulating mixing device of the plant protection machine plays a key role. Farmers first pour high-concentration pesticides into the container through the dosing hopper, and then turn on the water inlet pipe to let clean water flow into the mixing tank to mix the pesticide and water. During use, when mixing water and pesticides, the mixing rate is usually slow, resulting in reduced mixing efficiency. In addition, some impurities may be mixed into the liquid when adding pesticides and water, affecting the quality of the pesticides.

[0004] Therefore, a circulating pesticide mixing device for plant protection machinery was proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a circulating mixing device for plant protection machines, which solves the technical problems that the mixing rate is usually slow when mixing water and pesticides, resulting in reduced mixing efficiency, and that some impurities can be mixed into the liquid when adding pesticides and water, affecting the quality of the pesticides. The invention achieves the purpose of rapid and uniform mixing and feeding filtration.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a circulating mixing device for plant protection machinery, comprising a mixing tank, a controller fixedly installed on the outer wall of the mixing tank, an observation window provided on the outer wall of the mixing tank, a support ring fixedly sleeved on the outer wall of the mixing tank, a fixing frame fixedly installed at equal intervals around the bottom circumference of the support ring, a rapid and uniform mixing component provided inside the mixing tank, and a feeding filter component provided on the top of the mixing tank.

[0007] Preferably, the rapid and uniform mixing component specifically includes: a material-aggregating arc-shaped perforated plate, fixedly installed between the inner walls of the mixing tank; a perforated plate, fixedly installed between the inner walls of the mixing tank; a spray ring, fixedly installed at the bottom of the support plate; a motor, fixedly installed at the top of the mixing tank; a stirring rod one, equidistantly arranged inside the mixing tank; a stirring rod two, arranged inside the mixing tank; a solenoid valve, arranged at the bottom of the mixing tank; and a circulating pump, fixedly installed on the outer wall of the mixing tank.

[0008] Preferably, a rotating shaft is fixedly installed at the output end of the motor, and the other end of the rotating shaft movably passes through the top of the mixing tank and extends into the interior of the mixing tank. A rotating rod is fixedly installed at the other end of the rotating shaft, and a connecting rod is fixedly installed at the other end of the rotating rod. A feed pipe is fixedly installed on the outer wall of the connecting rod, and the outer wall of the feed pipe is slidably connected to the interior of the orifice plate.

[0009] Preferably, a sealing sleeve is fixedly installed on the top of the feeding pipe, the top of the sealing sleeve is in contact with the bottom of the material arc hole plate, and side rods are fixedly connected at equal intervals around the outer circumference of the feeding pipe, with an internal gear ring fixedly installed at the bottom of the side rods.

[0010] Preferably, the top of the first stirring rod movably passes through the bottom of the perforated plate and extends to the top of the perforated plate. The outer wall of the first stirring rod is rotatably connected to the inner wall of the perforated plate. A gear is fixedly installed on the top of the first stirring rod, and the surface of the gear meshes with the inner wall of the internal gear ring. The top of the second stirring rod is fixedly installed to the bottom of the connecting rod.

[0011] Preferably, discharge pipes are connected to both sides of the solenoid valve, and the other end of the discharge pipes is connected to the bottom of the mixing tank. Delivery pipes are connected to both sides of the circulating pump, and the other end of the delivery pipes is connected to the outer wall of the discharge pipes. The other end of another delivery pipe passes through the outer wall of the mixing tank and extends into the interior of the mixing tank, connecting to the outer wall of the spray ring. A motor drives a rotating shaft, causing the first rotating rod and connecting rod to rotate, and the discharge pipe rotates accordingly. Simultaneously, the side rod drives the internal gear ring to mesh with the gear, causing the first and second stirring rods to rotate and stir. The circulating pump draws the liquid pesticide from the bottom of the tank through the discharge pipe, and delivers it to the spraying ring through the delivery pipe. It sprays the pesticide from below the orifice plate upwards, creating convection with the mechanical agitation, accelerating the circulation of the pesticide and ensuring that the powder and liquid are fully dissolved. The material-gathering arc plate is fixed inside the tank, and its arc-shaped structure can gather the material towards the center, allowing the pesticide and water to mix for the first time. The solenoid valve is installed on the discharge pipe and can be opened and closed in real time according to the mixing needs. The observation window on the outer wall of the mixing tank allows for a direct view of the mixing status. The mounting bracket allows the device to be installed on the plant protection machine, thereby achieving a rapid and uniform mixing effect.

[0012] Preferably, the feeding filter assembly specifically includes: a feeding hopper, which is equidistantly connected and installed on the top of the mixing tank; a slot, which is circumferentially equidistantly opened on the top of the feeding hopper; and a lifting block, which is engaged and connected to the inner wall of the slot.

[0013] Preferably, a fixing ring is fixedly installed between the inner sides of the lifting blocks, and a filter belt is fixedly installed between the inner walls of the fixing rings. A cover plate is movably installed on the top of the feeding hopper, and a magnet is fixedly installed on the top of the cover plate. Multiple feeding hoppers are equidistantly distributed on the top of the mixing tank, allowing pesticides, water, or other adjuvants to be added simultaneously, avoiding the clogging problem of single-inlet feeding. The filter belt inside the fixing rings uses a fine mesh to intercept impurities such as clumps and debris in the pesticides, preventing them from entering the mixing tank and affecting stirring or clogging the pipes. The lifting blocks are engaged in the slots, allowing for quick disassembly of the fixing rings and filter belts for easy cleaning of residual impurities. The cover plate covers the top of the feeding hopper and is fixed by magnetic adsorption, thereby achieving the effect of feeding filtration.

[0014] This utility model provides a circulating pesticide mixing device for plant protection machines. It has the following beneficial effects: (1) This utility model can quickly mix water and medicine by setting up a fast and uniform mixing component. After the water and medicine enter, the controller motor drives the rotating rod one, connecting rod and feeding pipe to rotate.

The rotation of the feeding pipe drives the stirring rod two to stir, and at the same time drives the side rod and internal gear ring to rotate, which in turn drives the gear and stirring rod one to stir, promotes the flow of medicine liquid, achieves more uniform stirring, improves the stirring and mixing rate, and thus achieves the effect of fast and uniform mixing.

[0015] (2) This utility model filters impurities in water and medicine by setting up a feeding filter assembly. Open the cover and rotate it so that the two magnets attract each other.

[0022] A rotating shaft is fixedly installed at the output end of the motor 614. The other end of the rotating shaft passes through the top of the mixing tank 1 and extends into the interior of the mixing tank 1. A rotating rod 615 is fixedly installed at the other end of the rotating shaft. A connecting rod 616 is fixedly installed at the other end of the rotating rod 615. A feed pipe 617 is fixedly installed on the outer wall of the connecting rod 616. The outer wall of the feed pipe 617 is slidably connected to the interior of the orifice plate 612.

[0026] In this example, the rapid and uniform mixing component 6 can quickly mix water and medicine. After the water and medicine enter, the controller motor 614 drives the rotating rod 615, connecting rod 616, and feed pipe 617 to rotate. The water and medicine enter the material arc plate 611 for initial mixing, and then fall into the mixing tank 1 through the feed pipe 617.

[0027] Example 2: Based on Example 1, a preferred embodiment of the circulating pesticide mixing device for plant protection provided by this utility model is as follows: Figure 1-5 As shown: The feed filter assembly 7 specifically includes: a feed hopper 711, which is equidistantly connected and installed on the top of the mixing tank 1; a slot 712, which is circumferentially and equidistantly opened on the top of the feed hopper 711; and a lifting block 713, which is engaged and connected to the inner wall of the slot 712.

[0028] A fixing ring 714 is fixedly installed between the inner sides of the lifting block 713, and a filter belt 715 is fixedly installed between the inner walls of the fixing ring 714. A cover plate 716 is movably installed on the top of the feed hopper 711, and a magnet 717 is fixedly installed on the top of the cover plate 716.

[0029] In this example, the feed filter assembly 7 is set up to filter impurities in the water and medicine. The cover plate 716 is opened and rotated to make the two magnets 717 attract each other. Then the water and medicine are poured into the feed hopper 711. The filter belt 715 filters the impurities in the water and medicine, thereby achieving the function of feed filtration.

[0030] Working principle: First, the observation window 3 allows for direct observation of the mixing status. The mixing tank 1 can be fixedly installed on the plant protection machine via the fixing frame 5. When it is necessary to filter impurities in the water and pesticide, the cover plate 716 is opened and rotated, causing the magnets 717 on the cover plate 716 to attract each other and fix the cover plate 716. Then, water and pesticide are poured into the feed hopper 711 respectively. The filter belt 715 filters the impurities in the water and pesticide. When it is necessary to quickly mix the water and pesticide, after the water and pesticide enter, the controller motor 614 drives the rotating rod 615, connecting rod 616, and discharge pipe 617 to rotate.

The internal gear ring 6111 rotates, thereby driving the gear 6113 and the stirring rod 6112 to stir, quickly and evenly mixing the medicine and water inside the mixing tank 1. After stirring for a while, the circulation pump 6117 is started by the controller 2, and the liquid in the discharge pipe 6116 can be drawn out through the conveying pipe 6118 and transported to the spraying ring 613 for spraying, circulating the liquid. The solenoid valve 6115 is started by the controller 2, and the liquid can be discharged from the discharge pipe 6116 and transported to other links, thereby achieving the functions of rapid and even mixing and feeding filtration.
