Embodiment 1

[0020] In this example, ultraviolet-visible spectrophotometry is used to measure the dilution efficiency of the pesticide precision and high-efficiency mixing diluter:

[0021] First, accurately measure a certain amount of pesticide preparation samples (according to the recommended dosage for field use of pesticides). The pesticide formulations can be emulsifiable concentrate, microemulsion, or water emulsion. When the pesticide preparation is diluted in the field, the water consumption per mu of land is 50 L. The processing method is as follows:

[0022] A. Use the measuring cup cover 1 to measure a certain amount of pesticide preparation in the mixing barrel 2, add water to the 800 mL mark, tighten the measuring cup cover 1, turn it upside down 30 times at a speed of one back and forth every two seconds, and then pour it into the agricultural sprayer , fill up with water, stir 30 times, use a 100 mL syringe (with a 50 cm plastic tube at the head of the syringe) to randomly d...

Embodiment 2

[0030] In this example, the gravimetric method is used to determine the dilution efficiency of the pesticide precision and high-efficiency mixing diluter:

[0031] First, accurately weigh a certain amount of pesticide preparation (accurate to 0.0002 g; the pesticide formulation can be wettable powder or water suspension). When the pesticide preparation is diluted in the field, the water consumption per mu is 50 L. The processing method is as follows:

[0032] Standard treatment: Accurately weigh a certain amount of pesticide preparation and pour it into a 250 mL stoppered measuring cylinder, add 10 mL of water, fully shake and shake, then set the volume to 250 mL, turn it upside down at a speed of one back and forth every two seconds, so that the pesticide is fully Disperse evenly in water, immediately remove 25 mL with a pipette, transfer to a weighed centrifuge tube, and wait for centrifugation;

[0033]a. Use the measuring cup cover 1 to measure a certain amount of pestic...

Abstract

The invention discloses a precise and high-efficiency pesticide mixing diluter, which is composed of a measuring cup cover provided with scales and a dumbbell-shaped medicine mixing barrel, and the measuring cup cover and the medicine mixing barrel are screwed together. The measuring cup cover of the present invention is provided with a scale, which can accurately measure the pesticide and improve the accuracy of the dosage of the pesticide preparation in the field. Simultaneously, the drug mixing barrel of the present invention is dumbbell-shaped, and the diameter of the middle part is smaller. One, it is convenient to hold and mix the drugs upside down during the drug mixing process; The area is smaller than that at both ends, and a vortex is formed when the liquid medicine flows through the middle, which is convenient for the full mixing of the liquid medicine and improves the dilution efficiency of the pesticide.

Description

technical field [0001] The invention relates to a precise and high-efficiency pesticide mixing diluter, which belongs to the technical field of pesticide application equipment in plant protection. Background technique [0002] my country is a large agricultural country, and pests and weeds seriously restrict the safety and quality of food production. Chemical pesticides are an important means to ensure stable and high yields of food crops. One of the important indicators is to ensure that the deposition and distribution of pesticides are uniform. In addition to adopting the correct method of application, it is also necessary to ensure that the dosage of pesticide preparations in the field is applied accurately and the dilution must be uniform. At present, when pesticide preparations are mixed in the field, there are common phenomena such as inaccurate measurement of pesticide preparations, uneven dilution, and unstable control effects. In severe cases, it will lead to problem...
