Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to an ore feeding device of a vibrating screen. Background Art

[0002] Mineral resources, also known as mineral resources, refer to the aggregate of minerals or useful elements that are formed through geological mineralization, naturally occur in the earth's crust or buried underground or exposed on the surface, in solid, liquid or gaseous form, and have development and utilization value. Mineral resources are non-renewable resources and their reserves are limited. There are more than 160 known minerals in the world, of which more than 80 are widely used. According to their characteristics and uses, they are usually divided into four categories: 11 energy minerals; 59 metal minerals; 92 non-metallic minerals; and 6 water and gas minerals. There are a total of 168 types of minerals.

[0003] Feeding refers to delivering minerals from the storage bin to the receiving device. Feeding the vibrating screen refers to the feeding hopper feeding the minerals to the screen surface at the feeding end of the vibrating screen through the feeding belt, and then the vibrating screen performs the screening operation.

[0004] The existing vibrating screen feeding device throws the minerals evenly onto the vibrating screen, and then the vibrating screen shakes the minerals apart. However, the existing feeding device cannot increase the feed rate of the vibrating screen, otherwise the minerals are easily stacked when the vibrating screen shakes apart, causing the screen to be blocked.

[0005] Therefore, we have developed a feeding device for a vibrating screen that pre-screens the minerals. After the minerals are pre-screened, increasing the feed rate of the vibrating screen will not cause the vibrating screen to be clogged, thereby improving the screening efficiency.

[0027] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0028] Example 1

[0029] A feeding device for a vibrating screen, such as Figure 1 and Figure 2 As shown, it includes a supporting plate frame 1, a discharge box 2, a lower hopper 201, a dispersion component and a rotating component. The discharge box 2 is installed on the top of the supporting plate frame 1. A feed port is opened on the top of the discharge box 2, and a discharge port is opened at the bottom of the discharge box 2. Minerals enter from the feed port. A lower hopper 201 matching the discharge port is installed at the bottom of the discharge box 2. Minerals are thrown from the discharge port through the lower hopper 201. The lower hopper 201 is arranged in multiple numbers. By feeding ore at multiple points, the screen surface is covered to improve the utilization rate of the vibrating screen surface. A dispersion component is installed at the bottom of the lower hopper 201, and a rotating component is installed on the top of the discharge box 2.

[0030] like Figure 5 As shown, the dispersion component includes a fixed rod 10, a connecting plate 11, a rotating shaft 12, a throwing plate 13 and a second torsion spring 14. The fixed rods 10 are symmetrically welded on the left and right sides of the lower hopper 201, and the rotating shaft 12 is welded on the front lower part of the lower hopper 201. The connecting plate 11 connected to the rotating shaft 12 is installed on the fixed rod 10, and the throwing plate 13 is installed on the rotating shaft 12 through rotation. The second torsion spring 14 connected to the rotating shaft 12 and the throwing plate 13 is sleeved on the rotating shaft 12. The heavy mineral presses the throwing plate 13, so that the throwing plate 13 compresses the second torsion spring 14 and rotates clockwise downward on the rotating shaft 12 at the same time, so that the heavy mineral is thrown a short distance, the light mineral has a small force on the throwing plate 13, the throwing plate 13 rotates a small amplitude, and is thrown a long distance, thereby achieving a pre-screening effect.

[0031] like Figure 1-Figure 3 As shown, the rotating assembly includes a motor 3, a mounting frame 4 and a rotating plate 5. The motor 3 is fixed to the top of the discharge box 2 by bolts. The mounting frame 4 is sleeve-mounted on the output shaft of the motor 3. A plurality of rotating plates 5 are circumferentially welded on the mounting frame 4. The motor 3 can drive the mounting frame 4 and the rotating plate 5 to rotate. Through the stirring of the rotating plate 5, the mineral is discharged evenly, thereby achieving the effect of even ore feeding.

[0032] When people need to use the vibrating screen's ore-feeding device, this device can be used. First, start the motor 3, which drives the mounting frame 4 to rotate, and the mounting frame 4 drives the rotating plate 5 to rotate. Then, the mineral is put in from the feed port of the discharge box 2, and the rotating plate 5 stirs the mineral. When the stirred mineral flows from the discharge port of the discharge box 2 through the lower hopper 201 to the throwing plate 13, the heavy mineral will press the throwing plate 13, and the throwing plate 13 compresses the second torsion spring 14 and rotates clockwise downward on the rotating shaft 12 at the same time, so that the heavy mineral is thrown a short distance, while the light mineral has a small force pressing the throwing plate 13, and the amplitude of the rotation of the throwing plate 13 is small, so that the light mineral is thrown a long distance, thereby realizing the pre-screening of the mineral before feeding.

[0033] Example 2

[0034] On the basis of Example 1, Figure 4 As shown, it also includes a slide rail 7, a shielding door 8 and a handle 9. Slide rails 7 are opened on both sides of the lower hopper 201. The shielding door 8 is slidably installed on the slide rail 7. The handle 9 is installed on the upper part of the shielding door 8. When large pieces of minerals go out from the discharge port, the handle 9 can be pulled, and the handle 9 drives the shielding door 8 to slide upward on the slide rail 7 to adjust the size of the discharge port.

[0035] like Figure 3As shown, a first torsion spring 6 is also included. The rotating plate 5 is sleeved with the first torsion spring 6 connected to the mounting frame 4 and the rotating plate 5. When the rotating plate 5 rotates to heavy minerals, the rotating plate 5 will compress the first torsion spring 6. The first torsion spring 6 provides the rotating plate 5 with its restoring elastic force, thereby enhancing the ability of the rotating plate 5 to rotate the mineral.

[0036] If the size of the discharge port needs to be adjusted, the slide rail 7, the shielding door 8 and the handle 9 can be installed on the device. People pull the handle 9 to drive the shielding door 8 to slide up and down on the slide rail 7, thereby adjusting the size of the discharge port.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
