Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural equipment, and in particular relates to an intelligent pesticide proportioning device. Background Art

[0002] The traditional method of mixing pesticides is to mix manually according to the ratio or dilution factor in the instructions or to use mechanical devices for mixing. Mixers often mix based on their personal experience accumulated in the past. The traditional method of mixing pesticides often fails to achieve accurate mixing concentrations, resulting in the failure to exert the best efficacy of the pesticides and reducing work efficiency.

[0003] The patent with application number CN202321283102.X discloses an automatic proportioning device for agricultural pesticides, including a tank body, a water pipe, a drug pipe, a first screw cap, a second screw cap, a water storage chamber, a drug storage chamber, a water outlet pipe, a drug outlet pipe, a mixing tank, a first solenoid valve, a first water pump, a first meter, a second solenoid valve, a second water pump, a second meter, a liquid medicine pipe, a third solenoid valve, a through groove and a through hole; one end of the drug pipe is threadedly connected to the first screw cap, and one end of the water pipe is threadedly connected to the second screw cap; a through hole is provided on the outer wall of the tank body at the position corresponding to the drug pipe, the drug pipe is sleeved in the through hole, and one end of the drug pipe is arranged in the water storage chamber. In this scheme, an automatic proportioning structure is designed, which can accurately configure the required pesticides and ensure the use effect of the pesticides. Through the secondary mixing structure, it can be used immediately after being prepared, avoiding chemical reactions and crystallization of different dosage forms of drugs in a storage tank for a long time, further ensuring the efficacy of the pesticides. However, in this technical solution, the pesticide is first added to the medicine storage chamber through the dosing pipe, and then the pesticide is quantitatively transported to the mixing tank through the control system to be diluted and mixed with water. In this way, it will be difficult to ensure that the pesticide in the medicine storage chamber can be used up exactly every time. If there is any residue, the pesticide in the medicine storage chamber will be difficult to clean and collect. If it is accumulated in the medicine storage chamber for a long time, chemical reactions may occur or even crystallization may occur, which greatly reduces the efficacy of the subsequent use.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

[0005] The utility model aims to provide an intelligent pesticide proportioning device, which solves the problem in the prior art that when the pesticide is proportioned, the remaining pesticide is difficult to recover and stays in the pesticide storage room for a long time, which reduces the efficacy of the pesticide.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0008] Furthermore, the mixing tank is located below the water storage tank, the dosing pipe is tilted, and the inlet of the dosing pipe faces upward. By arranging the mixing tank below the water storage tank and tilting the dosing pipe, as long as the first solenoid valve and the second solenoid valve are opened, water and pesticides can automatically flow into the mixing tank without adding an additional water pump, which further saves manufacturing costs.

[0009] Furthermore, a rubber sheet is formed on the outer side wall of the first connection port to seal with the tube mouth of the dosing tube; an external thread is formed on the outer side wall of the first connection port to seal with the thread of the dosing tube, and an internal thread is formed on the inner side wall of the second connection port to seal with the thread of the pesticide bottle. The rubber sheet can seal the dosing tube to prevent the pesticide entering the dosing tube from leaking from the inlet of the dosing tube when the second solenoid valve is closed. In addition, the threaded connection between the pesticide bottle and the dosing tube makes the operation more convenient.

[0010] Furthermore, the mixing tank is also equipped with a stirring mechanism, which includes a stirring blade located inside the mixing tank and a motor fixedly connected to the bottom of the mixing tank, and the output shaft of the motor is drivingly connected to the stirring blade. The stirring mechanism can fully mix the water in the mixing tank with the pesticide to improve the efficacy of the pesticide.

[0011] Furthermore, a plurality of supporting legs are provided on the outer side wall of the water storage tank, and a connecting column is provided between the water storage tank and the mixing tank. The supporting legs can make the water storage tank more stable.

[0012] Furthermore, the water storage tank is provided with a water supply pipe, and the bottom of the mixing tank is provided with a medicine discharge pipe connected to the pesticide spraying device. The mixed pesticide can be transported to the pesticide spraying device through the medicine discharge pipe and then sprayed.

[0013] After adopting the above structure, the intelligent pesticide proportioner involved in the utility model, compared with the prior art, directly installs the pesticide bottle on the dosing tube by arranging a connecting component on the dosing tube. When diluting and proportioning, the amount of pesticide entering the mixing tank can be accurately measured by the second flow meter. After use, if there is any residual pesticide in the pesticide bottle, the pesticide bottle and the connecting component are directly removed from the dosing tube, and then the pesticide bottle is turned back to make the pesticide remaining in the connecting tube flow back into the pesticide bottle, so as to avoid the problem of long-term accumulation of pesticides in the dosing tube and the connecting component, which causes reduced efficacy.

The second flow meter 43 is installed at the output end of the second solenoid valve 42, and the second flow meter 43 is connected to the second solenoid valve 42 through electrical signals. The first flow meter 112 and the second flow meter 43 are respectively used to monitor the amount of water and the required amount entering the mixing tank 2, and the control panel 3 is used to give the data to be monitored. When the amount of pesticide entering and the amount of water entering reach the threshold, the first solenoid valve and the second solenoid valve 42 are respectively closed to prevent water and pesticide from continuing to enter the mixing tank 2. When use is completed, if there is any remaining pesticide in the pesticide bottle 5, the connecting component 6 is directly disassembled together with the pesticide bottle 5, so that the pesticide retained in the connecting pipe 61 flows back into the pesticide.

[0023] Preferably, the mixing tank 2 is located below the water storage tank 1, the dosing pipe 4 is tilted, and the inlet of the dosing pipe 4 faces upward. By arranging the mixing tank 2 below the water storage tank 1 and tilting the dosing pipe 4, as long as the first solenoid valve and the second solenoid valve 42 are opened, water and pesticides can automatically flow into the mixing tank 2 without adding an additional water pump, which saves more manufacturing costs.

The mixed pesticide can be transported to the pesticide spraying device through the drug discharge pipe 21, and then sprayed. When the water in the water storage tank 1 is insufficient, water is added to the water storage tank 1 through the water supply pipe 14.

[0028] The method of using the utility model is as follows: first, the required water consumption and the dosage of various pesticides are calculated according to the area where the pesticides need to be sprayed, and the values ​​are input through the control panel 3. Next, the pesticide bottle 5 is first connected to the second connection port 613 of the connection component 6, and then the connection component 6 and the pesticide bottle 5 are connected to the dosing tube 4. During the connection, as the first connection port 612 gradually penetrates into the dosing tube 4, the push rod 41 in the dosing tube 4 enters from the first connection port 612 and pushes open the blocking plate 62, so that the pesticide can enter the dosing tube 4. Then the device is started, the first solenoid valve and the second solenoid valve 42 are opened, so that water and pesticide can enter the mixing tank 2. At the same time, the stirring mechanism 7 starts to work, and when the first flow meter 112 and the second flow meter 43 detect that the flow rate reaches the threshold value, the first solenoid valve and the second solenoid valve 42 are closed. When the water and pesticide in the mixing tank 2 are evenly mixed, the stirring mechanism 7 is turned off. At this time, the pesticide with the final proportion can be transported to the spraying device through the discharge pipe 21, and the pesticide is sprayed by the spraying device. After use, the connecting component 6 is first disassembled together with the pesticide bottle 5, and then the pesticide is put upright. If there is any pesticide left, the pesticide in the tube body 611 will automatically flow into the pesticide bottle 5 for the next use.
