Description

Technical Field

[0001] The utility model relates to the technical field of pesticide use, in particular to a precise metering device for pesticide compounding. Background Art

[0002] Farmland is often plagued by multiple pests and diseases at the same time, and some pests and diseases may develop resistance to a certain component of pesticide. In order to solve the above problems, improve prevention and control efficiency and reduce the frequency of spraying, pesticides need to be mixed or compounded.

[0003] The utility model patent with application number CN201922318469.0 discloses a quantitative control device for the ratio of compound pesticide raw materials, including a metering box, four sets of stabilizing devices, a first connecting pipe, a control valve, a second connecting pipe, a third connecting pipe, a valve, a motor, a reduction box, a stirring rod, a coupling, a movable rod, a first connecting rod, a support rod, a push rod and a second connecting rod. A chamber is arranged inside the metering box, bosses are arranged at the bottom of the left and right ends of the metering box, and two sets of stabilizing devices are installed on the two sets of bosses. The output end of the first connecting pipe passes through the left end of the metering box and is connected to the chamber of the metering box. The output end of the control valve is connected to the input end of the first connecting pipe, and the output end of the second connecting pipe is connected to the input end of the control valve. A push-type control switch is arranged at the top of the control valve, and the input end of the second connecting pipe is connected to the external liquid raw material. When a certain amount of liquid is added to the quantitative control device for the ratio of compound pesticide raw materials, the liquid supports the floating ball to rise, and the floating ball drives the movable rod to rise, so that the right end of the first connecting rod rises with the top of the movable rod. By utilizing the principle of lever, the middle part of the first connecting rod is fixed in the vertical direction, and the left end of the first connecting rod descends, so that the push rod also descends, and the second connecting rod connected to the push rod drives the pressure head to descend, thereby causing the pressure head to descend and triggering the control switch at the top of the control valve, and closing the control valve, so that the raw medicine no longer enters the chamber of the metering box, and then the first connecting rod is fixedly connected to the push rod, and the valve is opened to allow the pesticide raw materials in the chamber of the metering box to enter the next process, thereby saving equipment costs and improving practicality.

[0004] However, this type of quantitative control device for the ratio of compound pesticide raw materials controls the amount of liquid medicine through a float in a metering box. When the upper surface of the liquid medicine fluctuates due to stirring, the float will also fluctuate up and down with the liquid medicine. As a result, when the liquid medicine may not have reached the required amount, the float will be lifted up by the waves of the liquid medicine, causing the valve to be closed in advance, resulting in inaccurate liquid medicine ratio, which needs further improvement.
