Description

Technical Field

[0001] The utility model relates to the technical field of stone processing, in particular to high-efficiency screening equipment for stone processing. Background Art

[0002] In the process of mining stone, stone screening machines are generally used. The existing stone screening machines are only simple fixed filter structures. The materials that can be filtered are small materials, and the materials that cannot be filtered are large materials.

[0003] The above method has the problem of incomplete screening. The large materials themselves are heavy and easy to stack on the vibrating plate, which can easily bring out the small materials, thus reducing the screening efficiency. Therefore, a high-efficiency screening device for stone processing is disclosed. Utility Model Content

[0004] Based on the deficiencies in the prior art mentioned in the above background technology, the utility model provides a high-efficiency screening equipment for stone processing.

[0005] The utility model overcomes the above technical problems by adopting the following technical solutions, specifically:

[0006] A high-efficiency screening equipment for stone processing comprises a vibrating frame, a supporting structure for supporting is arranged at the bottom of the vibrating frame, a plurality of groups of obliquely distributed rotating rollers are rotatably installed inside the vibrating frame, and the plurality of groups of rotating rollers are distributed in steps from top to bottom, a material guide plate arranged obliquely is fixed to the bottom of the vibrating frame, and each group of rotating rollers is located above the material guide plate, a plurality of groups of material blocking rods are fixed to the top of the vibrating frame, and each group of material blocking rods is respectively located between every two adjacent groups of rotating rollers, and a driving component for causing the vibrating frame to vibrate is installed on the supporting structure.

[0007] As a further solution of the utility model: the support structure includes a welding bracket, two groups of spring plates are fixed on the top of the welding bracket, and one end of the spring plate is fixed to the bottom of the vibration frame.

[0008] As a further solution of the utility model: the driving assembly includes a driving motor, a crankshaft and a connecting rod, both ends of the crankshaft are rotatably mounted on the welding bracket, the casing of the driving motor is fixedly mounted on the welding bracket, and the output shaft of the driving motor is coaxially fixed with the crankshaft, one end of the connecting rod is rotatably mounted on the vibration frame, and the other end of the connecting rod is rotatably mounted on the curved end of the crankshaft.

[0009] As a further solution of the utility model: a first material dividing plate is fixed to the bottom end of the material guide plate.

[0010] As a further solution of the utility model: a second material dividing plate is fixed to one end of the vibration frame.

[0011] As a further solution of the utility model: the first dividing plate and the second dividing plate are staggered with each other.

[0012] As a further solution of the utility model: a synchronous wheel coaxially arranged therewith is fixed at one end of each of the rotating rollers, and a synchronous belt is jointly sleeved on every two adjacent synchronous wheels; a second transmission wheel coaxially arranged therewith is fixed at one end of one of the rotating rollers, and a first transmission wheel is fixed at one end of the crankshaft; and the first transmission wheel and the second transmission wheel are jointly sleeved on a transmission belt.

[0013] After adopting the above structure, the utility model has the following advantages compared with the prior art:

[0014] During the vibration screening process, this equipment breaks up the stacked large materials so that they cannot bring out the small materials. At the same time, the rotating rollers move the large materials to slow down the speed at which they fall, making the screening time more sufficient. The small materials fall from the intervals between adjacent rotating rollers, and the rotating rollers use friction to quickly move the small materials into the guide plate below, making the screening faster and more sufficient.

[0022] In the utility model, the stone enters from the top of the vibration frame 5, the vibration frame 5 vibrates, the stone moves downward, the stone collides with the blocking rod 6, the large material accumulated in the stone is broken up, so that the large material cannot bring out the small material, because the multiple groups of rotating rollers 7 are distributed in a stepped manner from top to bottom, the accumulated large material is broken up each time it falls, further making it impossible for the large material to bring out the small material, making the screening more sufficient and efficient.

[0023] Specifically, the support structure includes a welding bracket 1, two sets of spring plates 2 are fixed on the top of the welding bracket 1, and one end of the spring plate 2 is fixed to the bottom of the vibration frame 5;

[0024] In the utility model, the spring plate 2 enables the vibration frame 5 to have a reset property and controls the vibration direction at the same time.

[0026] In the present invention, the driving motor 14 rotates the crankshaft 13 via the output shaft, and the crankshaft 13 causes the vibration frame 5 to reciprocate via the connecting rod 15, thereby generating vibration.

[0027] Specifically, a first material dividing plate 3 for guiding materials is fixed to the bottom end of the material guiding plate 16 .

[0028] Specifically, a second material dividing plate 4 for guiding materials is fixed to one end of the vibration frame 5 .

[0029] Specifically, the first material dividing plate 3 and the second material dividing plate 4 are staggered with each other, so that large and small materials can be collected separately.

The stone material collides with the baffle rod 6, and the large materials accumulated in the stone material are scattered, so that the large materials cannot carry the small materials out. Since multiple groups of rotating rollers 7 are distributed in a stepped manner from top to bottom, the large materials accumulated are scattered during each falling process, further making the large materials unable to carry the small materials out, making the screening more sufficient and efficient; the first transmission pulley 10 on the crankshaft 13 rotates accordingly. The first transmission pulley 10 and the second transmission pulley 12 rotate synchronously through the transmission belt 11. The second transmission pulley 12 drives the rotating roller 7 fixed to it to rotate accordingly. Every two adjacent rotating rollers 7 rotate synchronously, and the rotating direction of the rotating roller 7 is opposite to the falling direction of the stone material. Small materials fall intermittently from between adjacent rotating rollers 7, and the rotating rollers 7 quickly dial the small materials into the lower material guiding plate 16 by means of friction, making the screening faster and more sufficient.
