Description

Technical Field

[0001] The utility model relates to the technical field of pesticide production, in particular to a liquid pesticide mixing and stirring device. Background Art

[0002] Liquid pesticides are an important formulation, using liquids as carriers. The active ingredients in liquid pesticides are typically dispersed in the form of particles or molecules, making them less susceptible to decomposition or loss of efficacy. They offer excellent stability and can be applied directly by spraying or rain. They are suitable for pest control on large crops and offer a variety of flexible applications.

[0003] Liquid pesticides require mixing and stirring of their raw materials during production and processing. Currently, during the mixing and stirring process of liquid pesticides, since the pesticides themselves are toxic, a large amount of toxic and harmful gases will be produced during the mixing process. The emission of these gases into the work area will cause harm to the health of the workers. Utility Model Content

[0006] When using the liquid medicine mixing and stirring device of the utility model, the pesticide liquid raw material is added into the mixing tank from the feed pipe, and then the threaded cover is installed to close the feed pipe. The first driving device can be used to rotate the rotating shaft, and the liquid pesticide can be stirred and mixed by the stirring rod. During the mixing and stirring process, the second driving device can be used to rotate the fan blades at high speed. When the fan blades rotate at high speed, the gas generated by the mixing in the mixing tank can be extracted, and the extracted gas can be discharged into the filter box. The harmful gas can be filtered and purified by the activated carbon filter layer, and the gas is discharged from the exhaust pipe after filtration and purification.

[0007] Preferably, a support leg is installed at the lower end of the mixing tank, and there are four support legs in total, and the four support legs are distributed in an array about the mixing tank. The arrangement of the support legs can support the mixing tank.

[0008] Preferably, the lower end of the mixing tank is provided with a discharge pipe connected to the mixing tank, and a valve is provided on the discharge pipe. After the liquid pesticide is stirred and mixed, the valve is opened to discharge it from the discharge pipe.

[0009] Preferably, a first driving device is installed on the upper end of the cover plate, and the main shaft of the first driving device is connected to the axis of the rotating shaft. The first driving device can rotate the rotating shaft, thereby causing the stirring rod to stir and mix the liquid pesticide.

[0010] Preferably, a feed pipe is embedded in one side of the upper end surface of the cover plate, and a threaded cover is threadedly mounted on the feed pipe. Liquid pesticide can be added to the mixing tank through the feed pipe.

[0013] Preferably, symmetrically distributed clamping blocks are mounted on the side ends of the filter box, and the snap plates are snap-fitted to the clamping blocks. The arrangement of the snap plates and the clamping blocks allows the sealing cover to be mounted and fixed, and rotating the snap plates can release the fixing of the sealing cover, thereby allowing the activated carbon filter layer to be removed from the filter box.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: during the mixing and stirring process of liquid pesticides, the fan blades are rotated at high speed by the operation of the second driving device, so that the gas in the mixing tank can be extracted and discharged into the filter box, and the harmful gas can be filtered and purified through the activated carbon filter layer.
