[0019] This utility model discloses a novel vibrating screen structure that can improve screening efficiency, comprising a base 1, a vibrator round beam 2, a longitudinal beam 3, a main channel steel 6, a screen mesh 7, and bolts 9; the specific structure is as follows: Figures 1-3 As shown, a base 1 is provided in the screening area of ​​the ore block in the material yard, and a vibrator round beam 2 is horizontally mounted on the base. Five vertically arranged longitudinal beams 3 are welded sequentially along the length of the upper end face of the vibrator round beam 2, and the upper end faces of the five longitudinal beams 3 are horizontally coplanar. The main channel steel 6 is horizontally mounted on the upper end face of the five longitudinal beams 3 near its front end, and its opening slot faces forward. The screen 7 is a horizontally arranged rectangular structure, and its left and right ends are vertically turned upwards.

The screen 7 is screwed and fixed to the main channel steel 6 by the bolts 9, and then the vibrator drives the screen 7 to vibrate through the vibrator round beam 2 to perform screening operations.

[0020] like Figure 1 , Figure 2 As shown, each longitudinal beam 3 is a rectangular structure, and the five longitudinal beams 3 are aligned side by side. The longitudinal length of each longitudinal beam 3 is greater than the diameter of the exciter circular beam 2, and they are symmetrically arranged front and back relative to the exciter circular beam 2. An arc-shaped groove, coaxial with the exciter circular beam 2, is embedded in the middle of the lower surface of each longitudinal beam 3. Each arc-shaped groove matches the upper half of the exciter circular beam 2, and each longitudinal beam 3 is coaxially fitted onto the corresponding position on the exciter circular beam 2 through the arc-shaped groove and fixed by welding. The distance between the left side of the leftmost longitudinal beam 3 and the right side of the rightmost longitudinal beam 3 matches the transverse length of the main channel steel 6, and the lower surface of the main channel steel 6 is welded to the corresponding position of the upper end face of each longitudinal beam 3.

[0021] like Figure 1 , Figure 2 As shown, several vertically arranged reinforcing plates are welded sequentially and longitudinally along the length of the opening groove of the main channel steel 6, and each reinforcing plate matches the interior of the main channel steel 6, thus supporting and reinforcing the main channel steel 6.

[0022] like Figure 1 , Figure 2As shown, several horizontally arranged channel steel brackets 5 are arranged longitudinally at intervals on the upper end face of the five longitudinal beams 3 relative to the rear side of the main channel steel 6, and the opening slot of each channel steel bracket 5 is arranged facing the rear side; the transverse length of each channel steel bracket 5 is consistent with the transverse length of the main channel steel 6, and its height is less than the height of the main channel steel 6; the lower surface of each channel steel bracket 5 is welded and fixed to the corresponding position of the upper end face of each longitudinal beam 3, and ensures that its left and right ends are aligned with the left and right ends of the main channel steel 6 respectively.

[0023] like Figure 1 , Figure 2 As shown, side plates 4 are vertically attached to the left and right ends of the main channel steel 6, and the lower end of the left side plate 4 is fixedly connected to the upper end of the leftmost longitudinal beam 3, ensuring that the left side of the left side plate 4 and the left side of the leftmost longitudinal beam 3 are coplanar; the lower end of the right side plate 4 is fixedly connected to the upper end of the rightmost longitudinal beam 3, ensuring that the right side of the right side plate 4 and the right side of the rightmost longitudinal beam 3 are coplanar; the horizontal plane of the upper end of each side plate 4 is located above the horizontal plane of the two flanged end faces of the screen 7, and its longitudinal length is consistent with the longitudinal length of each longitudinal beam 3, and is attached to the left and right ends of each channel steel bracket 5, thereby covering the screen 7 at intervals through the two side plates 4, and limiting the material screened by vibration on the screen 7 through the side plates 4.

[0024] The screen 7 of this utility model is made of polyurethane, and its screen holes are all square holes of 10*15mm; for example Figures 1-3 As shown, each bolt 9 does not interfere with the screening action of the screen 7, and the lateral length of the screen 7 matches the spacing between the two side plates 4; the rear end of the screen 7 extends into the rear side channel steel bracket 5, and an outer frame 8 is also provided in the material yard block ore screening area relative to the lower surface of the screen 7 near its rear edge; the upper surface of the outer frame 8 is horizontally coplanar with the upper surface of the main channel steel 6, and the rear end of the screen 7 is supported by the outer frame 8.

[0025] like Figure 1 , Figure 2 As shown, on the lower surface of the screen 7, vertical stiffeners 10 are arranged at intervals along the horizontal direction relative to each channel steel bracket 5. The height of each stiffener 10 is consistent with the height difference between the main channel steel 6 and the channel steel bracket 5, and they do not interfere with the screening operation of the screen 7. The screen 7 is supported by the contact between the lower end face of the stiffener 10 and the upper surface of the corresponding channel steel bracket 5.

[0026] The working principle of this utility model: During use, the vibrator transmits the excitation force of the vibrator beam 2 and drives the screen 7 to vibrate, thereby performing screening operations. During this process, since the screen 7 is designed with one side fixed and the rest suspended on the channel steel bracket 5, the impact force is large, thereby improving the screening efficiency and effectively solving the problem of screen 7 sticking to material under various working conditions of lump ore. When the screen 7 needs to be replaced, the bolts 9 are removed and the screen 7 is pulled out to perform the screen 7 replacement operation.

[0027] The beneficial effects of this utility model are: (1) The present invention adopts a design in which the screen 7 is fixed on one side and the rest is suspended on the channel steel bracket 5, which makes the impact force large and thus effectively solves the problem of screen 7 sticking to material under various working conditions of block ore; (2) The screen 7 of this utility model is fixed by bolts 9, which has a simple structure, is easy to disassemble and assemble, and has good stability, thus solving the problem that the screen 7 is easy to fall off; (3) This utility model only requires replacing the screen 7 to carry out the screening operation again, and this process saves time and effort and saves costs.
