Description

TECHNICAL FIELD

[0001] The utility model relates to agitating unit technical field, concretely relates to agitating unit for powder safety production. BACKGROUND

[0002] Pesticide and fertilizer powder is an important material indispensable in agricultural production, which plays an important role in promoting crop growth and improving the yield and quality of agricultural products. During the production of pesticide and fertilizer powder, various raw materials need to be mixed together through an agitating unit.

[0003] However, when the raw materials are placed and accumulated for a long time, clumps will be generated inside. The clumped raw materials may cause the equipment to run poorly, increase mechanical wear and tear, and even cause equipment failure, posing a safety hazard to the operators. At the same time, the clumped raw materials are difficult to disperse rapidly and uniformly throughout the mixture during the stirring process, resulting in a significant reduction in stirring effect, which ultimately leads to uneven distribution of effective ingredients in the product, affecting the overall quality and stability of the product.

[0004] A patent with publication number CN221714042U is disclosed in the prior art, which includes a support and a mounting bracket. The support is fixedly connected to the mounting bracket at the top, and the mounting bracket is fixedly connected to the agitating barrel. A valve pipe is provided on the side wall of the agitating barrel, and an agitating shaft is rotatably connected to the bottom panel of the agitating barrel. An electric motor is installed at the bottom of the mounting bracket. Through the design of the sieve plate, the fine raw materials and clumped raw materials are effectively separated, allowing the various raw materials to be more uniformly mixed during the subsequent stirring process, improving the quality and consistency of the product. Since the clumped raw materials are separated in advance, the mechanical impact and wear caused by large clumps of raw materials during the stirring process are reduced, prolonging the service life of the agitating equipment and reducing the risk of uneven stirring or blockage caused by large clumps of material, thereby reducing the risk of equipment failure and safety accidents.

[0005] The existing devices, including the above-mentioned patent, gradually expose the shortcomings of the prior art with use, mainly in the following aspects:

[0006] First, when the powder raw materials are placed and accumulated for a long time, clumps will be generated inside. The powder raw materials need to be crushed and refined using an agitating unit before being packed. When the existing agitating unit stirs the clumped powder, the stirring structure simultaneously stirs the clumped raw materials and the powder raw materials, causing repeated stirring of the powder raw materials, increasing the kinetic energy consumption and reducing the stirring efficiency.

[0007] Second, during the packing process of the stirred materials, the powder is prone to leakage in the external working environment, posing a safety hazard to the operators in the working environment.
