Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hoppers, in particular to a hopper device and a material conveying equipment. BACKGROUND

[0002] In the field of coal and chemical industry, hoppers are often used to convey materials. For example, a belt conveyor needs to use a hopper to discharge materials. For another example, materials stored in a chemical enterprise need to be transferred to another place, and the materials need to be first packed into bags and then loaded into a vehicle for transfer.

[0003] In the prior art, in order to prevent the material from blocking the discharge port, a complex anti-blocking structure is usually configured.

[0004] For example, a Chinese invention patent with the publication number CN115384951A discloses an anti-blocking funnel assembly, which includes a support and a funnel assembly. The funnel assembly is connected with the support and includes a fixed funnel and a movable funnel. The fixed funnel has a material discharge cavity with a top opening and a bottom opening. The movable funnel is located at the lower end of the fixed funnel and is connected with the support. The movable funnel includes a plurality of plate segments arranged in a circumferential direction along the bottom opening. The plurality of plate segments enclose a material passing cavity opposite to and communicating with the bottom opening. At least one of the plurality of plate segments is movable along the radial direction of the bottom opening relative to the fixed funnel.

[0005] The above patent technology mainly relies on the change of the movable funnel to achieve anti-blocking. However, in fact, if the material has already blocked the discharge port of the fixed funnel, even if the movable funnel is opened, the blocking problem cannot be solved.

[0006] During the process of the material falling from the hopper, if the material falls along one side of the hopper quickly instead of falling uniformly and slowly along multiple sides, the material is more likely to block the discharge port.

[0007] Therefore, it is necessary to provide a new hopper device and a material conveying equipment. SUMMARY

[0008] The present application aims to overcome the shortcomings of the prior art and provide a hopper device and a material conveying equipment. In a normal state, the flow splitting cone blocks the discharge port of the hopper to prevent foreign matters from falling into the discharge port and causing blocking. In use, the flow splitting cone is raised below the material inlet of the hopper and rotates. The annular channel formed between the flow splitting cone and the wall surface of the hopper is a material falling channel, which can slow down the flow of the falling material. The rotating flow splitting cone also distributes the falling material around, avoiding the concentration of the material on one side and causing the blocking of the discharge port. The performance of the product is improved.

[0045] The motor 4 is fixedly installed at the lower end of the connecting rod 5, and the motor 4 is connected with the diverging cone 2 through a transmission mechanism 41.

[0046] ​When the hopper device is in the initial state, the flow splitting cone 2 is in the lowered state, and the bottom of the flow splitting cone 2 is in the discharge port 12 of the hopper 1.

[0047] When the hopper device is in the working state, the motor 4 is in the stopped state, the flow splitting cone 2 is in the raised state, and the flow splitting cone 2 is below the feed port 11 of the hopper 1 and rotates around the connecting rod 5.

[0048] The hopper device provided by the application comprises a hopper 1, a flow splitting cone 2, a lifting driving mechanism 3, a motor 4, a connecting rod 5, and the like.

[0050] The flow splitting cone 2 is conical and inverted in the hopper 1, wide at the bottom and narrow at the top. The flow splitting cone 2 has a cone cavity 23 inside, for mounting the motor 4 and the lower end of the connecting rod 5.
