Description

Technical Field

[0001] This utility model relates to the field of ore sorting, and more specifically, to an ore sorting vibrating screen. Background Technology

[0002] Vibrating screens are mainly divided into linear vibrating screens, circular vibrating screens, and high-frequency vibrating screens. According to the type of vibrator, vibrating screens can be divided into single-shaft vibrating screens and dual-shaft vibrating screens. Single-shaft vibrating screens use a single unbalanced weight to excite the screen box to vibrate. The screen surface is inclined, and the motion trajectory of the screen box is generally circular or elliptical. Dual-shaft vibrating screens use two unbalanced weights that rotate synchronously in opposite directions to excite the screen. The screen surface is horizontal or gently inclined, and the motion trajectory of the screen box is linear. Vibrating screens include inertial vibrating screens, eccentric vibrating screens, self-centering vibrating screens, and electromagnetic vibrating screens.

[0003] Since the shape and size of ores are not uniform, coarse and fine ores can be separated during the screening process. However, medium-volume ores slightly larger than the screen openings are still mixed with large-volume ores, making it inconvenient to perform secondary screening or replace the filter screen. In order to screen various ores more precisely and quickly, a vibrating screen for ore sorting is proposed to solve the above problems. Utility Model Content

[0004] To overcome the problem in the existing technology where irregular ore volume easily clogs the filter holes, resulting in imprecise screening, this utility model provides an ore sorting vibrating screen, including a base plate, a base fixedly installed on the top of the base plate, a vibration spring fixedly installed on the top of the base, a vibration tray inserted into the inside of the base, the vibration tray being connected to the vibration spring, and a vibration motor fixedly installed on the outer wall of the vibration tray.

[0005] A screening cylinder is fixedly installed on the top of the vibrating tray, a first material pipe is fixedly installed on the side wall of the screening cylinder, a second material pipe is fixedly installed on the side wall of the screening cylinder away from the first material pipe, a separation box is fixedly installed on the top of the bottom plate, a slot is opened on the side of the separation box opposite to the screening cylinder, the second material pipe extends into the slot, and a turning assembly is fixedly installed on the top of the separation box.

[0013] Beneficial effects: The beneficial effects of adopting the technical solution of this utility model are as follows: (1) By setting a first material pipe and a second material pipe on the screen cylinder and connecting the coarse mesh filter to the first material pipe, the material will vibrate continuously under the drive of the vibrating tray after entering the screen cylinder. The smallest ore will fall directly through the fine mesh filter to the second material box for discharge, while the larger ore will pass through the coarse mesh filter during the continuous shaking process for secondary screening in the separation box. The staff can directly collect the small-sized ore from the second material pipe.

[0014] (2) The minerals entering the separation box will first accumulate inside the third material box. A guide pipe is installed on one side of the third material box, which is the same as the medium-sized filter screen. The continuously rotating flipping component will push the mineral material to move. During the movement, the medium-sized ore will pass through the medium-sized filter screen into the fourth material box. Finally, the largest volume ore will remain in the third material box. This equipment can screen and classify different sizes of ore at one time, and the sorting is more refined, which is convenient for material collection. Attached Figure Description

The inner wall of the second material box 7 is inclinedly installed with a guide plate 71. The side wall of the second material box 7 has a discharge chute connected to the second material pipe 42. When the vibrating motor 31 drives the vibrating tray 3 to vibrate, the screen cylinder 4 will vibrate together, thereby screening the ore inside the first material box 6. The second material box 7 is used to briefly receive fine ore and transport it to the second material pipe 42 for discharge. In addition, the material turning assembly 8 includes a motor frame 81, which is fixedly installed on the top of the separation box 9. A servo motor 82 is fixedly installed inside the motor frame 81.
