Technical Field

[0001] The present invention relates to the technical field of efficacy test, and particularly relates to an efficacy test device for acaricides. Background Art

[0002] Plant acaricides are a type of pesticide specifically used to control harmful mites on plants. Their main function is to kill or control the growth and reproduction of harmful mites. Harmful mites include various types such as spider mites, gall mites, and phylloxera mites, etc. They can cause serious harm to plants, affecting the growth and yield of plants. After the production of acaricides, it is necessary to test their efficacy.

[0003] Currently, for the efficacy test device of acaricides, although it can test acaricides, when setting up a control group, it is not possible to spray the medicine on the experimental group and the control group simultaneously, resulting in the inability to ensure that the dosages of the medicine sprayed on the experimental group and the control group are the same, reducing the effect of the acaricide test. Therefore, there is an urgent need to design an efficacy test device for acaricides. Summary of the Invention

[0021] Please refer to the attached Figure 1 - attached Figure 2, in a preferred embodiment, the liquid injection assembly includes: a bracket 3, the bracket 3 is fixedly installed on the top of the barrel body 1, and an electric telescopic rod 4 is installed on the top of the bracket 3. Below the horizontal side of the bracket 3, there is a U-shaped frame 5, and the output end of the electric telescopic rod 4 is installed on the top of the horizontal side of the U-shaped frame 5. Two symmetrically arranged medicine cylinders 6 are fixed on the top of the barrel body 1, and a piston disc slides inside the medicine cylinder 6. The ends of the two vertical sides of the U-shaped frame 5 are respectively fixedly installed on the tops of the two piston discs. The U-shaped frame 5 and the piston disc cooperate to squeeze out the medicine inside the medicine cylinder 6; Add acaricides with different concentrations into the two medicine cylinders 6, then open the barrel door 2, clamp the plant leaves on the fixture 19, and close the barrel door 2. It should be noted that the fixture 19 is a mature prior art, and this document does not make any improvements to it, so it will not be elaborated here; Then open the solenoid valve and start the electric telescopic rod 4 to drive the U-shaped frame 5 to move downward.

Due to the setting of the reciprocating spiral groove 20, when the sliding column 21 rotates, it will also move along the path of the path groove 30, so as to realize the rotation and up and down movement of the sliding column 21. Further, the sliding column 21 drives the telescopic end of the first telescopic rod 16 to rotate and move up and down, and the telescopic end of the first telescopic rod 16 drives the clamp 19 and the clamped plant leaves to rotate and move up and down, so as to ensure that the medicament sprayed from the spraying holes 22 can be evenly sprayed on the plant leaves, and the treatment methods of the experimental group and the control group are synchronous and the same, ensuring the accuracy of the acaricide test.
