Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a hopper structure and a case packing machine. Background Art

[0002] At present, steel companies are accelerating the implementation of closed environmentally friendly material yards, which makes steel companies face the dual pressure of environmental protection and cost reduction. Ports can meet the requirements of site and technical level for mixed ore, and are becoming the best development site for commercial mixed ore. The mixed ore process is that two or more bucket wheel excavators take materials according to the ratio, send them to the same process through belt conveyors for mixing, and then transport them to the stacking site through bucket wheel excavators to form finished ore. In the current actual mixed ore operation, due to the shortcomings of traditional hoppers such as insufficient adaptability, the quality of the mixed ore products is uneven and the color difference is more prominent.

[0003] In addition, traditional hoppers are mostly vertically arranged, and the hopper discharge channel is a structure with a larger upper part and a smaller lower part. The upper end of the hopper is the feed port, and the lower end is the discharge port. The lower discharge port is set above the conveyor belt. When the material is fed into the hopper from top to bottom, it falls onto the conveyor belt by its own gravity, and is thus conveyed to the subsequent process. Since the hopper discharge channel is mostly a conical structure with a larger upper part and a smaller lower part, the more the material flows downward, the smaller the flow area of ​​the discharge channel becomes, and the friction and extrusion force between the material and the hopper shell, and between the material and the material becomes greater and greater, resulting in very poor fluidity of the material in the hopper. The material often sticks to the inner wall of the hopper discharge channel. In severe cases, the discharge channel is blocked, affecting the material transportation efficiency. Utility Model Content

[0004] The problem to be solved by the utility model is: how to improve the adaptability of the hopper in different application occasions and how to avoid the clogging of the material discharge channel of the hopper.

In addition, a scraping mechanism is provided in the second section of the hopper body.

[0029] like Figures 1 to 4As shown, the hopper structure of an embodiment of the present invention includes: a hopper body, a mixing mechanism and a scraping mechanism, the hopper body includes a first section 1 and a second section 2 distributed in sequence from top to bottom, the mixing mechanism is arranged corresponding to the first section 1, the mixing mechanism includes a mixing body 3, the mixing body 3 is arranged inside the first section 1, the mixing body 3 is used to switch between the first position and the second position inside the first section 1, the mixing body 3 is used to mix different materials with each other at the first position, the scraping mechanism is arranged corresponding to the second section 2, the scraping mechanism includes a scraping body 41, the scraping body 41 is arranged to fit the inner wall of the second section 2, and the scraping body 41 is used to move along the inner wall of the second section 2.

[0030] Specifically, this hopper structure can be applied to the transportation of non-ferrous metal mineral materials, in which the hopper body is larger than the traditional hopper. After the material enters the hopper body, it falls downward from the center position inside the hopper body. The first position above is the center position inside the first section 1, and the second position is the edge position inside the first section 1. When the belt conveyor transports two or more materials, the mixing body 3 needs to be switched to the first position to achieve mutual mixing of the materials; when the belt conveyor transports only one material, the mixing body 3 needs to be switched to the second position. When the mixing body 3 is in the second position, the material will not fall on the mixing body 3 to avoid affecting the falling of the material. In this way, two or more materials can be mixed simultaneously during the uninterrupted operation of the belt conveyor, and a smooth transition can be achieved when transporting only one material.

[0031] In this embodiment, combined with the Figures 1 to 4 As shown, the hopper structure is modified based on the traditional hopper. Specifically, a movable mixing mechanism is installed in the first section 1 of the hopper body. When the belt conveyor conveys two or more materials, the mixing body 3 of the mixing mechanism is moved to the first position of the first section 1. At this time, the mixing body 3 can mix the materials falling into the first section 1 with each other to achieve a good stirring effect. When the belt conveyor conveys only one material, there is no need to perform a mixing operation. The mixing body 3 can be moved to the second position. In this way, two or more materials can be mixed while the belt conveyor is running uninterruptedly, and a smooth transition can be achieved when conveying one material alone. In addition, a scraping mechanism is provided in the second section 2 of the hopper body. The scraping body 41 of the scraping mechanism can clean the materials adhering to the inner wall of the second section 2, thereby avoiding blockage of the discharge channel and allowing the material to be discharged smoothly.

The multiple blade groups 32 work together to mix different types of materials to achieve a good stirring effect.

[0034] Optionally, the blade assembly 32 includes a sleeve 321 and blades 322 , the sleeve 321 is sleeved on the rotating shaft 31 , and a plurality of blades 322 are distributed at intervals along the circumference of the sleeve 321 .

A plurality of blades 322 are spaced apart along the circumference of the sleeve 321. The blades 322 are preferably fan-shaped and evenly spaced at approximately 90° angles. It can be understood that the rotating shaft 31, sleeve 321, and blades 322 together constitute the agitator. During operation, the agitator continuously changes the direction and trajectory of materials at different points, mixing them together and achieving a good mixing effect.

To prevent material from flowing out of the first and second elongated slots 11, 12, a flexible sealing structure can be installed at the first and second elongated slots 11, 12. This structure neither affects the movement of the rotating shaft 31 along the length of the first and second elongated slots 11, 12, nor prevents material from flowing out of the first and second elongated slots 11, 12.
