preparation example Construction

[0054] The preparation method of pure natural plant insecticide, described preparation method is suitable for preparing above-mentioned pure natural plant insecticide, and the method steps are as follows:

[0055] S1: Take Cnidium Fructus Cnidii, camphor, tobacco leaf, chamae chamaejasma, flavescens, licorice and nuxychia by weight and put them into the grinder successively to grind into powder;

[0056] S2: Add the mixed powder obtained in step S1 into the leaching kettle, add water, emulsifier and dispersant according to the proportion, heat and stir fully;

[0057] S3: After cooling the mixture obtained in step S2, put it into a centrifuge for high-speed centrifugation, collect the finished product and put it in a medicine tank, and close the medicine tank.

[0058] The grinding machine described in S1 includes a grinding box 1; a feed hopper 11 is arranged at the center of the top of the grinding box 1; a grinding seat 12 is fixedly connected to the grinding box 1 through ...

Embodiment approach

[0059] As an embodiment of the present invention, a set of push rods 3 are fixedly connected to the outer wall of the conical block 2; the push rods 3 include a conical end block 31, a first connecting rod 32 and a second connecting rod 33 ; The first connecting rod 32 and the second connecting rod 6 are provided with a first cavity 34; the inner wall of the first cavity 34 is slidably connected with a first push plate 35, and the first push plate 35 is connected by a spring Fixed on the top side wall of the first cavity 34; the bottom end of the first connecting rod 32 is fixed on the side wall of the tapered block 2; the bottom end of the second connecting rod 33 and the bottom end of the tapered end block 31 Both are fixedly connected with a first connecting rod 36; the first connecting rod 36 at the bottom end of the second connecting rod 33 extends into the first cavity 34 of the first connecting rod 32, and the end is fixedly connected to the first push plate 35 On; the ...

Abstract

The invention belongs to the technical field of pesticides, and relates to a pure natural botanical insecticide and a preparation method thereof. The preparation method includes the steps that: S1, fructus cnidii, camphor, tobacco leaves, herba lysimachiae, radix sophorae flavescentis, liquorice and semen strychni are weighed according to the weight part ratio and sequentially put into a grinding machine to be ground into powder; S2, the mixed powder obtained in the step S1 is added into a leaching kettle, water, an emulsifying agent and a dispersing agent are added according to a ratio, heating, and uniform stirring are performed; and S3, after the mixture obtained in the step S2 is cooled, the mixture is put into a centrifugal machine to be subjected to high-speed centrifugal separation, a finished product is collected and put into a chemical agent tank, and the chemical agent tank is closed. When materials are put into a grinding box, the materials cannot be uniformly laid in a grinding seat, as a result, the grinding efficiency is reduced, and the grinding quality of grinding balls on the materials is influenced. With the pure natural botanical insecticide and the preparation method thereof adopted, the above problems can be solved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a pure natural plant insecticide and a preparation method thereof. Background technique [0002] In agricultural production, in order to ensure the yield and quality of agricultural products, it is necessary to use a large amount of chemical pesticides. Chemical pesticides have greatly increased agricultural output. However, almost all pesticides will affect the ecosystem: some pesticides have a pungent smell, and inhalation of large amounts will cause harm to the human body; some pesticide residues will damage the soil structure and affect future harvests ; Some pesticide residues will be concentrated in the food chain, destroying the food chain. Modern studies have shown that plant extracts are recognized worldwide as broad-spectrum, high-efficiency, low-toxicity, easy-to-degrade, non-residual pesticides, and have no drug resistance. any contamination. [0003] There are ...
