DETAILED DESCRIPTION

[0022] The present application will now be described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0023] like Figure 1-5 As shown, a diamond micro powder multi-stage vibrating screening device comprises a rotating sleeve 2 and a plurality of screen boxes 1 connected in sequence from top to bottom, the screen mesh apertures of the plurality of screen boxes 1 gradually decrease from top to bottom, and a discharge port 20 is provided on the screen box 1; the rotating sleeve 2 vertically penetrates the plurality of screen boxes 1 and is rotatably arranged; a first adjusting rod 50 is vertically slidably arranged inside the rotating sleeve 2, a first clamping rod 52 is arranged on the first adjusting rod 50 corresponding to the plurality of screen boxes 1, a first clamping groove 54 is arranged on the peripheral wall of the rotating sleeve 2, the first clamping rod 52 is slidably clamped with the first clamping groove 54, and a plate brush 53 is arranged at one end of the first clamping rod 52 away from the first adjusting rod 50; a first shifting rod 51 is radially arranged on the top of the first adjusting rod 50, and the first shifting rod 51 passes through the corresponding first clamping groove 54 and is located outside the screen box 1.

[0024] The apertures of the corresponding screens in the plurality of screen boxes 1 gradually decrease from top to bottom, thereby sorting out material particles of different sizes.

[0025] A top cover is provided on the top of the screen box 1 at the top, and a feed port 21 is provided on the top cover; the rotating sleeve 2 is rotatably arranged with the top cover, and can also play a certain limiting role on the rotating sleeve 2 at the same time.

[0026] When the first lever 51 is pulled upward with force, the first adjusting rod 50 together with the first clamping rod 52 arranged thereon all move upward synchronously, and the first clamping rod 52 and the first lever 51 will be clamped by the first clamping slot 54 to limit the current position of the first adjusting rod 50. At this time, the plate brush 53 is away from the screen; the entire equipment is in a normal screening state; when the second lever 61 is pressed downward with force, the first adjusting rod 50 together with the first clamping rod 52 arranged thereon all move upward synchronously, and the first clamping rod 52 and the first lever 51 will be located at the bottom of the first clamping slot 54. At this time, the plate brush 53 is in contact with the screen. As the rotating sleeve 2 rotates, the plate brush 53 will rotate synchronously, thereby gradually cleaning the material on the screen, thereby accelerating the movement of the material to the discharge port 20.

[0027] The rotating sleeve 2 can be driven to rotate by a motor, and the motor can be arranged on the top of the rotating sleeve 2. It should be conceivable that the rotating end of the motor is connected to the rotating sleeve 2, and the motor itself can be arranged on a frame such as a frame arranged on the top cover.

[0028] Under the action of the rotating sleeve 2, when the material on the screen is discharged, the rotating brush 53 can clean the material on the screen, thereby accelerating the movement of the material toward the outer wall of the screen box 1, and then the material is quickly discharged from the discharge port 20, thereby improving work efficiency.

[0029] In some other embodiments, the height of the brush 53 is gradually reduced along the direction of the rotating sleeve 2 toward the outer peripheral wall of the screen box 1 , so that the materials are more easily gathered near the outer peripheral wall of the screen box 1 .

[0030] In some further embodiments, a second adjusting rod 60 is vertically slidably provided inside the rotating sleeve 2, and a second clamping rod 62 is provided on the second adjusting rod 60 corresponding to several screen boxes 1, and a second clamping groove 64 is provided on the peripheral wall of the rotating sleeve 2. The second clamping rod 62 is slidably engaged with the second clamping groove 64, and a rotating roller 63 is rotatably provided at the end of the second clamping rod 62 away from the second adjusting rod 60, and the outer peripheral wall of the rotating roller 63 is provided with bristles; a second shifting rod 61 is radially provided on the top of the second adjusting rod 60, and the second shifting rod 61 passes through the corresponding second clamping groove 64 and is located outside the screen box 1.

[0031] The structures of the second adjusting rod 60, the second clamping rod 62 and the second clamping slot 64 are respectively the same as the first adjusting rod 50, the first clamping rod 52 and the second clamping slot 64, wherein one end of the rotating roller 63 is rotatably arranged on the end surface of the second clamping rod 62, and when the second lever 61 is pressed downward, the bristles on the rotating roller 63 can contact the screen, and at the same time, as the rotating sleeve 2 rotates, the rotating roller 63 will roll on the screen, and the bristles thereon can abut against the aperture on the screen, thereby playing the role of clearing the aperture.

[0032] In some further embodiments, the first clamping groove 54 is provided with a first limiting protrusion 55 on both side walls along the vertical direction. When the first clamping rod 52 is located below the two first limiting protrusions 55, the brush 53 is in contact with the corresponding screen, and when the first clamping rod 52 is located above the two first limiting protrusions 55, the brush 53 is away from the corresponding screen; the second clamping groove 64 is provided with a second limiting protrusion 65 on both side walls along the vertical direction. When the second clamping rod 62 is located below the two second limiting protrusions 65, the bristles are in contact with the corresponding screen, and when the second clamping rod 62 is located above the two second limiting protrusions 65, the bristles are away from the corresponding screen.

[0033] Specifically, the first clamping groove 54 is provided with a first limiting protrusion 55 on both side walls along the vertical direction. The limiting of the first adjusting rod 50 will be achieved by the cooperation between the first clamping rod 52 and the two first limiting protrusions 55, and the limiting of the second adjusting rod 60 will be achieved by the cooperation between the second clamping rod 62 and the two second limiting protrusions 65.

[0034] In some further embodiments, there are four screen boxes 1 in total, and a discharge port 20 is disposed on the outer peripheral wall of each of the four screen boxes 1 .

The multiple first connecting handles 70 and the multiple second connecting handles 71 are all arranged at intervals in the circumferential direction along the outer wall of the screen box 1. During installation, the first connecting handle 70 and the second connecting handle 71 are opposite to each other and are connected by bolts 72. The first spring 74 is located between the first connecting handle 70 and the second connecting handle 71. When the nut 73 on the bolt 72 is tightened, the first spring 74 is compressed, and the vibration transmission effect is enhanced. When the nut 73 on the bolt 72 is loosened, the compression of the first spring 74 is reduced, and the vibration transmission effect is reduced.

[0038] In some further embodiments, a vibrator 4 is provided on the outer peripheral wall of the screen box 1 at the bottom.

[0039] The vibrator 4 is arranged on the outer wall of the bottommost screen box 1. For example, two vibrators 4 may be arranged.
