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 dose 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 50L. 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 tank 2, add water to the 800mL 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 100mL syringe (with a 50cm plastic tube at the head of the injector) to randomly draw 5 po...
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 0.0002g; 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 50L. The processing method is as follows:
[0032] Standard treatment: Accurately weigh a certain amount of pesticide preparation and pour it into a 250mL stoppered measuring cylinder, add 10mL of water, shake it well, then set the volume to 250mL, turn it upside down at a speed of one back and forth every two seconds, so that the pesticide is fully and evenly dispersed in the In water, immediately remove 25mL 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 pesticid...

Abstract
The invention discloses a precise efficient mixing diluter for pesticides. The precise efficient mixing diluter comprises a measuring cup cover with scales and a dumbbell-shaped pesticide mixing barrel, wherein the measuring cup cover is in threaded connection with the pesticide mixing barrel. The scales are arranged on the measuring cup cover of the precise efficient mixing diluter for pesticides, so that the pesticides can be accurately measured and taken and the accuracy of dosage of the pesticides in field application can be increased. The pesticide mixing barrel of the precise efficient mixing diluter for pesticides is dumbbell-shaped and the diameter of the middle part is smaller, so that a user is convenient to hold for reversely mixing pesticides during a pesticide mixing process, and meanwhile, the liquid pesticides flow up and down during the reversing process, the cross section area of the middle part of the pesticide mixing barrel is less than the area of the two ends, and the liquid pesticides can be fully mixed when the liquid pesticides flow by the middle part and form the vortex, so that the diluting efficiency of the pesticides is increased.
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...
