Description

TECHNICAL FIELD

[0001] The application relates to a hopper structure with uniform feeding. BACKGROUND

[0002] In a traditional hopper structure, the flowability and distribution state of the material in the hopper are often affected by various factors, such as the particle size, humidity, density of the material, and the shape and size of the hopper, as well as the feeding speed. When these factors are not conducive to the smooth flow of the material, it will lead to uneven distribution of the material in the hopper, thereby causing a series of problems.

[0003] The existing patent (publication number: CN213792148U) discloses a conical crusher feeding hopper with uniform feeding. The hopper body is provided with an inlet frame at the top, the front and back surfaces of the inlet frame are fixedly connected with bushings, and the inside of the bushings is slidably connected with a vertical rod.

[0004] The above-mentioned scheme solves the problem that when the current conical crusher feeding hopper is fed too much, the material will be congested, the material will be discharged slowly, and even the feeding hopper will be blocked. However, the angle of the deceleration plate in the above-mentioned scheme cannot be adjusted, and the fixed angle of the deceleration plate cannot be adjusted according to the production demand, thereby limiting the optimization of the production efficiency and reducing the production efficiency.
