Description

Technical Field

[0001] This utility model relates to the field of mineral raw material screening technology, specifically a material feeding bin with screening function. Background Technology

[0002] Metal mineral processing is the process of extracting metals or metal compounds from ores and further processing them. The first step is crushing and grinding, where large pieces of ore are broken down into smaller, finer pieces using crushers and grinding mills to facilitate subsequent extraction. Next is mineral processing, which uses principles such as gravity, magnetism, and buoyancy to separate valuable minerals from gangue. Common methods include gravity separation, magnetic separation, and flotation.

[0003] In the process of metal mineral processing, it is usually necessary to place the minerals inside a designated container. When feeding the minerals, the separation efficiency of metal compounds is usually related to the size of the minerals. Existing feeding silos usually cannot screen the minerals by size during the feeding process, which can easily lead to reduced mineral processing efficiency and inconvenience. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a material feeding bin with screening function, which has the advantage of conveniently completing the overall material screening. It solves the problem that in the process of metal mineral processing, minerals usually need to be placed in a designated container. When feeding minerals, the separation efficiency of metal compounds is usually related to the size of the minerals. Existing feeding bins usually cannot screen the size of the minerals during the feeding process, which easily leads to reduced mineral processing efficiency and is extremely inconvenient.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A material feeding bin with screening function includes a feeding channel. The inner wall of the feeding channel is provided with two guide members that have a gap between them and form a funnel shape. One of the guide members has a driving member at its end that drives it to move to change the size of the gap and is connected to the feeding channel. The inner side of the feeding channel is provided with a vibrating member that drives the other guide member to vibrate. The opposite ends of the two guide members are inclined. The outside of the feeding channel is provided with a feeding end and a transport frame that forms a material transport between the lower end of the guide member and the feeding end.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the transport frame consists of a transport channel and a collection container, both of which are located outside the unloading channel. The top of the collection container is open, and the inner wall of the transport channel is polished.

[0010] Furthermore, the material feeding channel is provided with a hanging ear on its exterior, and the material feeding channel is connected to the collection container through the hanging ear.

[0011] Furthermore, the inner front and rear walls of the feeding channel are provided with limiting slide rails extending into the interior of the movable guide. The guide is made of bent stainless steel metal plate and is polished and coated with an anti-oxidation coating.

[0012] Furthermore, the driving component includes a control threaded rod that is threadedly connected to the feeding channel and whose end is rotatably connected to the guide component via a bearing.

A plastic striking component that generates periodic impacts when rotating is connected to the outside of the vibration cam.

[0014] This utility model provides a material feeding hopper with screening function. By setting guide members, the material enters from the top of the feeding channel and passes through the funnel-shaped gap formed by two inclined and opposite guide members. The drive member controls the horizontal displacement of one guide member through threaded adjustment to change the gap width, thereby adjusting the particle size of small particles during the screening process. The vibrating member drives the other guide member to vibrate continuously to prevent material jamming. The material can be effectively screened according to its particle size at the gap. The screened small particles continue to move along the feeding channel, while the large particles slide into the conveyor frame along the inclined end of the guide members to complete the screening. It has the advantage of conveniently completing the screening of the entire material. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a material feeding bin with screening function, including a feeding channel 1. The inner wall of the feeding channel 1 is provided with two guide members 2 that are separated from each other and form a funnel shape. One end of one guide member 2 is provided with a driving member 3 that drives it to move to change the size of the gap and is connected to the feeding channel 1. The inner side of the feeding channel 1 is provided with a vibrating member 4 that drives the other guide member 2 to vibrate. The opposite ends of the two guide members 2 are inclined. The outer side of the feeding channel 1 is provided with a conveying frame 5 that forms a material transport between the feeding end and the lower end of the guide member 2.

[0021] Furthermore, the transport frame 5 consists of a transport channel and a collection container. Both the transport channel and the collection container are located outside the unloading channel. The top of the collection container is open, and the inner wall of the transport channel is polished.

[0022] Polished inner walls reduce material adhesion and loss during transport, open-type collection containers facilitate quick cleaning, and the split design meets the transportation needs of the collection containers.

[0023] Furthermore, the outside of the feeding channel 1 is provided with a hanging ear, and the feeding channel 1 is connected to the collection container through the hanging ear.

[0024] The lug connection enables quick installation and disassembly of the collection container, while bolt fixing ensures structural stability during transportation and facilitates maintenance and replacement.

[0025] Furthermore, the inner front and rear walls of the feeding channel 1 are provided with limiting slide rails that extend into the interior of the movable guide 2. The guide 2 is made of bent stainless steel metal plate and is polished and coated with an anti-oxidation coating.

[0026] The limit slide rail ensures that the guide component 2 can only move in one direction. The stainless steel material and anti-oxidation coating enhance corrosion resistance, and the polished surface reduces material friction resistance.

[0027] Furthermore, the drive component 3 includes a control threaded rod 31 that is threadedly connected to the feeding channel 1 and whose end is rotatably connected to the guide component 2 via a bearing. A scale rod 32 is provided on the outside of the feeding channel 1, with its position corresponding to the position of the control threaded rod 31.

[0028] When the control threaded rod 31 is rotated, the guide 2 moves horizontally along the limit slide rail, and the scale line of the scale rod 32 displays the gap adjustment amount in real time, so as to facilitate the adjustment of the particle size of the sieve.

[0029] Furthermore, the vibrating component 4 includes a power motor 41 fixed to the inner wall of the driving component 3. A vibration cam 42 is fixedly provided on the outside of the output shaft of the power motor 41. A plastic striking component 43 that generates periodic impacts when rotating is externally connected to the vibration cam 42.

[0030] The motor 41 drives the vibration cam 42 to rotate, and the plastic striking part 43 periodically impacts the back of the guide 2 with the eccentric movement of the cam 42, generating high-frequency vibration;

[0031] The combined structure of cam 42 and striking element 43 converts rotational motion into vibrational energy. The plastic material reduces noise and equipment wear, and the high-frequency vibration effectively prevents material from clogging the screening gap.

[0032] Working principle:

[0033] By setting guides, the material enters from the top of the feeding channel 1 and passes through the funnel-shaped gap formed by two inclined and opposite guides 2. The drive unit 3 controls the horizontal displacement of one guide 2 through thread adjustment to change the gap width, thereby adjusting the particle size of small particles during the screening process. The vibrating unit 4 drives the other guide 2 to vibrate continuously to prevent material jamming, so that the material can be effectively screened according to the particle size at the gap. The screened small particles continue to move along the feeding channel 1, while the large particles slide into the conveyor frame 5 along the inclined end of the guide 2 to complete the screening.
