[0025] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1As shown, the rice field water direct supply type plant protection drug mixing device of this embodiment includes a drug storage container 1 and a mud and water refiner 2. The inlet end of the mud and water refiner 2 is connected to a suction pump 3 for pumping water in the field into the mud and water refiner 2. The outlet end of the mud and water refiner 2 is connected to the inlet end of the drug storage container 1 through a water supply pipe 4. The water supply pipe 4 is connected to a drug adding component 5 for adding drug concentrate to the water supply pipe 4. The outlet end of the drug storage container 1 is connected to a drug outlet pipe 6, and an output pump 7 is provided on the drug outlet pipe 6. When the paddy field water direct supply type plant protection medicine mixing device is working, the suction pump 3 can be used to take muddy water from the field and send it to the muddy water refiner 2. After the mud and sand in the muddy water are refined by the muddy water refiner 2, they are sent to the medicine storage container 1 through the water delivery pipe 4 under the pumping pressure of the suction pump 3, and in the process of being transported through the water delivery pipe 4, the medicine dosing component 5 adds the medicine stock solution to the water delivery pipe 4 to obtain the medicine. When the medicine needs to be supplied to the plant protection operation machine (spraying device, etc.) of the plant protection machinery, the medicine in the medicine storage container 1 can be pumped out by the output pump 7 under pressure. It realizes the direct water extraction from the paddy field, so that the plant protection machinery does not need to load a large water tank, which is conducive to reducing the weight of the whole machine, and can effectively avoid the problem of the plant protection machinery getting stuck when driving, improve the driving stability, and also avoid the problem of stopping to replenish water, which is conducive to improving the efficiency of plant protection operations.

[0027] In this embodiment, preferably, the medicine storage container 1 is a sealed container with an automatic pressure relief exhaust valve. The use of a sealed container can avoid splashing of the aqueous solution and prevent debris from entering the container. At the same time, the sealed container is provided with an automatic pressure relief exhaust valve, which can timely balance the air pressure inside and outside the sealed container to ensure the normal entry and exit of the aqueous solution.

[0028] In this embodiment, Figure 2 As shown, the mud and water refiner 2 includes a shell 21 with an inner cavity 211, and the inner cavity 211 is provided with an input port 212 and an output port 213. The input port 212 is connected to the suction pump 3 as the inlet end of the mud and water refiner 2, and the output port 213 is connected to the inlet end of the medicine storage container 1 through the water supply pipe 4 as the outlet end of the mud and water refiner 2. A stirrer 22 is installed in the inner cavity 211. The stirrer 22 is a prior art, which includes a stirring paddle and a motor. The motor drives the stirring paddle to rotate to drive the mud and water in the inner cavity 211 to rotate at a high speed. At the same time, the stirring paddle plays a role of striking and cutting the mud and sand in the mud and water, so that the mud and sand particles are further refined to become a thin mud slurry that meets the operating requirements of the plant protection operation machine. Preferably, the shell 21 is composed of two upper and lower shells spliced ​​together, and its manufacture and maintenance are simple and convenient.

[0029] In this embodiment, a plurality of annular protrusions 214 are arranged in intervals from top to bottom on the inner wall of the inner cavity 211. The muddy water will continuously hit the annular protrusions 214 during the high-speed rotation driven by the agitator 22, which can further improve the refinement effect of the mud and sand particles. Preferably, the annular protrusions 214 are in the shape of fangs with the tip facing the middle of the inner cavity 211, so that the refinement effect of the mud and sand particles is better.

[0030] In this embodiment, Figure 3 and Figure 4 As shown, the suction pump 3 includes a pump housing 31 with a pump chamber 311, a rotor 32 rotatably installed in the pump chamber 311, and an annular magnetic pole stator 33 installed in the pump chamber 311 and sleeved outside the rotor 32. The pump chamber 311 is connected to a water inlet pipe 34 and a water outlet pipe 35. One end of the rotor 32 is connected to an axially extending rotating shaft 36, on which an impeller 37 and a moving grinding ring 38 are installed. The moving grinding ring 38 is located between the impeller 37 and the rotor 32. A fixed grinding ring 39 is installed on the inner wall of the pump chamber 311. The fixed grinding ring 39 is sleeved outside the moving grinding ring 38, and an annular gap is provided between the inner circumference of the fixed grinding ring 39 and the outer circumference of the moving grinding ring 38 for muddy water to pass through. The main structure of the suction pump 3 is the same as that of the existing impeller type water pump, mainly with the addition of a fixed grinding ring 39 and a moving grinding ring 38. When working, the impeller 37 forces the muddy water to pass through the annular gap between the inner circumference of the fixed grinding ring 39 and the outer circumference of the dynamic grinding ring 38, so as to grind the mud and sand in the muddy water, thereby refining the mud and sand particles.

[0031] In this embodiment, the inner circumference of the fixed grinding ring 39 and the outer circumference of the movable grinding ring 38 are both provided with a plurality of fang-shaped annular grinding protrusions 301 surrounding the rotating shaft 36, and the plurality of fang-shaped annular grinding protrusions 301 of the fixed grinding ring 39 and the plurality of fang-shaped annular grinding protrusions 301 of the movable grinding ring 38 are sequentially spaced along the axial direction of the rotating shaft 36. This can further improve the grinding and refining effect of the sediment.

[0032] In this embodiment, the distance between the inner circumference of the fixed grinding ring 39 and the outer circumference of the dynamic grinding ring 38 gradually decreases along the direction from the impeller 37 to the rotor 32, so that larger particles of sand can also enter the annular gap between the inner circumference of the fixed grinding ring 39 and the outer circumference of the dynamic grinding ring 38 and be gradually ground and refined, so that larger particles of sand can be ground and the suction pump 3 can be prevented from being blocked.

[0033] In this embodiment, the pump housing 31 is installed on a buoyancy component 8 that can carry the suction pump 3 and float on the water surface. The buoyancy component 8 can float on the water surface and can automatically adjust its height according to the water level in the field, so that the water suction port of the pump housing 31 is always at a suitable water suction height, thereby ensuring the stability and reliability of water suction.

[0034] In this embodiment, the buoyancy component 8 has a water passage 81, one end of which is connected to the water inlet pipe 34, and the other end of which is open downward and is provided with a coarse filter 9. The coarse filter 9 can avoid sucking large particles of sediment and filter impurities such as leaves and weeds floating in the field, thereby improving the stability and reliability of the work. In addition, the above structure is simple and compact, and has a good suction effect.

[0035] In this embodiment, an ultrasonic rangefinder 10 is preferably provided on the buoyancy component 8, and the ultrasonic rangefinder 10 is used to detect the depth and clarity of the water source. A strong reflected wave signal received means that the water source is clear, and a weak signal means that the water source is turbid. The ultrasonic rangefinder 10 is connected to a controller that controls the start and stop of the suction pump 3. When the ultrasonic rangefinder 10 detects that the water depth is within the set depth range value and the clarity of the water source is within the set range value, the controller controls the suction pump 3 to increase the power and double the water storage. When the ultrasonic rangefinder 10 detects that the water depth is within the set depth range value and the clarity of the water source is lower than the set range value, or when the ultrasonic rangefinder 10 detects that the water depth is lower than the set depth range value, the controller controls the suction pump 3 to stop working to prevent blockage.

[0036] In this embodiment, Figure 5 As shown, the dosing assembly 5 includes a medicine storage bottle 51 for storing the original medicine solution, which is arranged above the water delivery pipe 4. The bottom of the medicine storage bottle 51 is provided with a medicine outlet and an air inlet. The medicine outlet is connected to the water delivery pipe 4 through a medicine delivery pipe 52, and the air inlet is connected to an air inlet pipe 53. The dosing assembly 5 is similar to human infusion. By using the Bernoulli principle, the rapid flow of muddy water in the water delivery pipe 4 forms a low pressure. At the same time, under the water pressure formed by the height difference, the original solution in the medicine storage bottle 51 enters the water delivery pipe 4 through the medicine delivery pipe 52, and finally mixes with the thin muddy water in the water delivery pipe 4. When the original medicine solution in the medicine storage bottle 51 flows out, air will enter the medicine storage bottle 51 through the air inlet pipe 53. The dosing assembly 5 has a simple and compact structure, low cost, and stable and reliable operation.

[0037] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and changes obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
