[0002] The sand and gravel vibrating screen is used for single-layer or multi-layer screening of granular and small-block solid materials of different specifications. When sand and gravel are placed on the screen surface, the vibrator drives the screen surface to screen the sand and gravel.

[0003] When the existing sand and gravel vibrating screen screens sand and gravel, the sand and gravel will be directly loaded onto the screen surface, and the vibration of the screen surface will drive the sand and gravel to vibrate and move while being separated. In this process, excessive accumulation of sand and gravel on the vibrating screen will increase the screening burden of the vibrating screen, and the vibration effect of the vibrating screen will be reduced due to the increase in the amount of sand and gravel accumulation, thereby reducing the effect of sand and gravel vibration. At the same time, a large amount of sand and gravel can easily cause blockage of the screen surface, reducing the effectiveness and integrity of the vibrating screen screening. Therefore, in order to solve the above problems, a vibrating screen mechanism for sand and gravel processing is proposed. Utility Model Content

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides a vibrating screen mechanism for sand and stone processing as shown in Figures 1-3 Figure 5. It includes a vibrating screen main body 1. At the top of the vibrating screen main body 1, there is a feeding structure 2. The feeding structure 2 includes a feeding box 201 and a partition 202. The feeding box 201 is fixedly arranged at the top of the vibrating screen main body 1. The partition 202 is movably arranged in the inner cavity of the feeding box 201. At the top of the partition 202, there are fixedly arranged a plurality of flow dividing blocks 203 for preventing blockage of sand and stone feeding. The top heights of the flow dividing blocks 203 are the same, and the inclination angles of the hypotenuses of the flow dividing blocks 203 are different. At the top of the partition 202, there are symmetrically and fixedly arranged baffle plates. The top of the feeding box 201 is provided with a box cover. In the state of no feeding, the feeding box 201 can be closed through the box cover, so as to provide safety protection for the structures arranged in the feeding box 201, avoid external objects from falling or touching the structures in the feeding box 201, and provide convenience and safety for the storage of the structures in the feeding box 201. When sand and stone are fed, the box cover is opened to expose the inner cavity of the feeding box 201. When the sand and stone fall from the feeding box 201 onto the vibrating screen main body 1 for screening work, they will first fall onto the flow dividing blocks 203 arranged in the feeding box 201. The heights of the flow dividing blocks 203 are the same. Therefore, the distances for the sand and stone to reach the flow dividing blocks 203 are the same. However, the cross-section of the flow dividing blocks 203 is triangular, and the inclination angles of the sides of the flow dividing blocks 203 are different. Therefore, the distances and speeds for the sand and stone to slide onto different flow dividing blocks 203 are different, so that the falling times of the sand and stone can be staggered, and then the diversion effect on the sand and stone can be achieved, avoiding the phenomenon of incomplete vibration caused by a large amount of sand and stone falling each time. The diverted sand and stone can fall onto the vibrating screen main body 1 at different times, and the continuous vibration of the vibrating screen main body 1 is used to drive the sand and stone falling on it to vibrate and change positions, so as to improve the effect and integrity of the vibration screening of the sand and stone. An anti-collision pad 303 is fixedly sleeved on the outer wall of the partition 202. The anti-collision pad 303 is used to avoid direct collision between the partition 202 and the inner wall of the feeding box 201. The anti-collision pad 303 is any one of elastic rubber or elastic silica gel. The setting of the anti-collision pad 303 avoids direct collision between the partition 202 and the inner wall of the feeding box 201, buffers the collision force between the partition 202 and the feeding box 201, plays a safety protection role, extends the service lives of the partition 202 and the feeding box 201, and reduces the use costs of both.

[0026] Further, the feeding structure 2 further includes a blanking hole 204 and a protruding block 205. The blanking holes 204 are respectively opened at the top end of the partition plate 202 and the bottom end of the inner cavity of the feeding box 201. The blanking holes 204 are used for the discharge of sand and gravel from the inner cavity of the feeding box 201. The protruding block 205 is fixedly arranged at the bottom end of the inner cavity of the feeding box 201. The protruding block 205 is used for the accumulation of sand and gravel in the inner cavity of the feeding box 201. The blanking holes 204 are opened at both the bottom end of the partition plate 202 and the bottom end of the feeding box 201, providing space for the falling of sand and gravel from the feeding box 201. The protruding blocks 205 are all in a semi-circular arc shape. The protruding blocks 205 are arranged at the bottom end of the inner cavity of the feeding box 201 and between adjacent blanking holes 204. When the sand and gravel fall from the partition plate 202 to the bottom end of the inner cavity of the feeding box 201, due to the arc-shaped setting of the protruding blocks 205, even if the sand and gravel fall onto the protruding blocks 205, they will slide along the outer wall of the protruding blocks 205 into the blanking holes 204, avoiding the accumulation of sand and gravel in the inner cavity of the feeding box 201, improving the integrity and effectiveness of the falling of sand and gravel from the feeding box 201. At the same time, the cross-section of the blanking hole 204 opened at the bottom end of the feeding box 201 is trapezoidal, enabling the sand and gravel to reduce the falling volume when passing through the blanking hole 204 at the bottom end of the feeding box 201 after falling from the partition plate 202, thereby reducing the vibration burden of the vibrating screen main body 1. Thus, the screening quality of the vibrating screen main body 1 for sand and gravel is further improved;

[0027] Finally, a support structure 3 is provided between the partition plate 202 and the feed box 201. The support structure 3 includes a support rod 301 and an elastic component. The support rod 301 is fixedly arranged at the bottom end of the partition plate 202. The support rod 301 is used to limit the position of the partition plate 202 in the inner cavity of the feed box 201. The elastic component is arranged on the outer wall of the partition plate 202. The elastic component is used for the movable support of the position of the partition plate 202. The elastic component includes a support spring 302. The support spring 302 is fixedly arranged at the top end of the partition plate 202. The support spring 302 is used for the movement of the partition plate 202 under the pressure state. The support rod 301 is a telescopic rod. The top end of the support rod 301 is fixedly arranged with the bottom end of the partition plate 202. The bottom end of the support rod 301 is fixedly arranged with the inner wall of the feed box 201 through a fixedly connected rectangular plate. The rectangular plate is fixedly arranged on the inner wall of the feed box 201. There is a space between the outer wall of the partition plate 202 and the inner wall of the feed box 201. Since the feed box 201 is fixedly arranged with the vibrating screen main body 1, the feed box 201 and the partition plate 202 will also vibrate along with the vibration of the vibrating screen main body 1. Therefore, the partition plate 202 can move due to the change in the weight of the sand and gravel fed. Thus, a downward or upward force can be generated on the support rod 301. Furthermore, in cooperation with the elastic performance of the support spring 302, the effectiveness of the movement of the partition plate 202 can be improved. When the partition plate 202 is pressed, a pulling force is generated on the support spring 302. On the contrary, the support spring 302 will drive the partition plate 202 to reset its position. With the continuous feeding of sand and gravel, the partition plate 202 will move repeatedly. Thus, the sand and gravel falling onto the partition plate 202 can be shaken, ensuring the effectiveness and efficiency of the sand and gravel falling from the partition plate 202.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
