Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a vibrating mechanism and a high-efficiency vibrating screening machine. Background Art

[0002] Sand is an essential basic raw material in the construction field. There are many impurities in sand, such as gravel, garbage, etc., and the sand particles in the sand are also divided into different grades. Different uses require different particle sizes of sand. In the field of construction, sand is often used, and the sand transported to the construction site usually needs to be screened.

[0003] When performing sand screening operations, sand and gravel need to be put into the screen box. Since the feed port of the screen box cannot regulate the sand and gravel input rate, the sand and gravel will accumulate on the screen plate, affecting the screening operation of the screening machine. Utility Model Content

[0011] By adopting the above technical solution, the adjusting frame can cooperate with the grid to block the sand and gravel in the hopper. After the adjusting frame is displaced and coincides with the grid, the sand and gravel can fall into the screen box from the gap between the adjusting frame and the grid.

[0012] Preferably, the feeding part includes an eccentric disk a slidably connected to an adjustment frame and a motor a arranged on one side of the hopper, the output end of the motor a is connected to the eccentric disk a, a rotating shaft is arranged at the bottom end of the eccentric disk a deviating from the axis, a slide groove is provided on one side of the adjustment frame, and the rotating shaft at the bottom of the eccentric disk a is slidably connected to the slide groove provided on one side of the adjustment frame.

A slide groove is provided inside the hopper 201, and both sides of the adjustment frame 203 are embedded in the slide groove and slidably connected to the hopper 201. The motor a205 drives the eccentric disk a204 to rotate to drive the adjustment frame 203 to slide in the hopper 201. The eccentric disk a204 can be driven to rotate by the motor a205, thereby driving the adjustment frame 203 to slide in the hopper 201. Through cooperation with the grid 202, the sand and gravel put into the hopper 201 can enter the screen box 101 at a uniform speed and in an orderly manner, thereby completing the screening operation.

[0034] Embodiment 2

[0035] See also Figure 3 , Figure 4 and Figure 5 The utility model provides a technical solution: a high-efficiency vibration screening machine, including a feeding part 2, a grid 202, an adjustment frame 203 and an eccentric disk a204:

[0036] A plurality of grids 202 are arranged transversely inside the hopper 201, and the grids 202 are located directly below the adjustment frame 203. A plurality of blocks are arranged transversely on the adjustment frame 203, and the number of the blocks is equal to the number of the grids 202. The gap between the grids 202 is equal to the width of the blocks. A slide groove is arranged on one side of the adjustment frame 203, and a rotating shaft is arranged at the bottom end of the eccentric disk a204 away from the axis. The rotating shaft at the bottom of the eccentric disk a204 passes through the adjustment frame 203 and the adjustment frame The sliding connection of the slide groove opened on one side of 203 can drive the eccentric disk a204 to rotate through the motor a205, thereby driving the adjusting frame 203 to slide back and forth in the hopper 201, so that the adjusting frame 203 can cooperate with the grid 202, thereby blocking the sand and gravel in the hopper 201. After the adjusting frame 203 is displaced and overlaps with the grid 202, the sand and gravel can fall into the screen box 101 from the gap between the adjusting frame 203 and the grid 202.

[0037] Embodiment 3

[0038] See also Figure 1 , Figure 2 and Figure 6 The utility model provides a technical solution: a vibration mechanism, including a screening part 1 and a vibration part 3:

[0039] The vibration part 3 is arranged at the bottom of the screen box 101, including an eccentric shaft 301 rotatably arranged inside the vibration part 3, a driven disk 302 arranged on both sides of the eccentric shaft 301, a driving rod 303 rotatably connected to the driven disk 302, and an eccentric disk b304 rotatably connected to the driving rod 303, a motor b305 is arranged at the bottom of the screen box 101, and the output end of the motor b305 is connected to the eccentric disk b304, and the motor b305 drives the eccentric disk b304 to rotate, so as to drive the driving rod 303 to drive the eccentric disk b304 to rotate. The eccentric disk b304 can be driven to rotate by the motor b305, so that the eccentric disk b304 drives the two driving rods 303 to rotate, so that the two eccentric shafts 301 can rotate simultaneously at the same rotation angle, thereby reducing the phenomenon that the two eccentric shafts 301 do not have reverse synchronization when rotating, thereby reducing energy consumption.

[0040] Working principle: First, put the sand and gravel to be screened into the hopper 201, then start the motor a205, and drive the eccentric disk a204 to rotate through the motor a205, thereby driving the adjusting frame 203 to slide in the hopper 201, and the adjusting frame 203 can cooperate with the grid 202 to block the sand and gravel in the hopper 201. After the displacement of the adjusting frame 203 coincides with the grid 202, the sand and gravel can fall into the screen box 101 from the gap between the adjusting frame 203 and the grid 202. The reciprocating sliding adjusting frame 203 can make the sand and gravel put into the hopper 201 enter the screen box 101 at a uniform and orderly speed, and be screened by the screen plate 102. The larger ones are discharged from the discharge port a103, and the smaller ones are discharged from the discharge port b104. During the screening process, the dust cover 105 can effectively prevent dust in the sand and gravel from splashing.

[0041] Secondly, by means of the driving rod 303 arranged in the vibration part 3, the eccentric disk b304 is driven to rotate through the motor b305, so that the eccentric disk b304 drives the two driving rods 303 to rotate, so that the two eccentric shafts 301 can rotate simultaneously at the same rotation angle, reducing the phenomenon of reverse synchronization when the two eccentric shafts 301 rotate, thereby reducing energy consumption.
