Examples

Referring to fig. 1 to 4, the present embodiment provides a waste rock conveying and screening apparatus, which mainly includes: conveyer belt 1, backup pad 2, buffer plate 3 and screening board 4. Backup pad 2 sets up in the top of conveyer belt 1, and the buffer board 3 is installed in backup pad 2, and the slope of screening board 4 sets up in the top of conveyer belt 1, and the bottom of screening board 4 is parallel with the upside of conveyer belt 1. A screening gap 41 is reserved between the screening plate 4 and the conveying belt 1, and a material passing gap 42 is reserved between one end of the screening plate 4 and the edge of the conveying belt 1. The waste rock with smaller volume can pass through the screening gap 41, and the waste rock with larger volume moves with the conveyer belt 1 from the material passing gap 42.

When the waste rocks move to the screening plate 4 along with the conveying belt 1, the waste rocks with small volumes can pass through the screening gap 41, the waste rocks with large volumes are blocked by the screening plate 4, and the waste rocks with large volumes move to the material passing gap 42 along the screening plate 4 under the driving of the conveying belt 1, so that the waste rocks with different volumes are distributed in different areas of the conveying belt 1, and thus, the waste rocks can be screened and conveyed.

The buffer plate 3 is provided with a U-shaped notch 31, and a filter plate 32 is fixed in the U-shaped notch 31. After the waste rocks dropping downward fall on the filter plate 32, the waste rocks with smaller volume can pass through the filter holes on the filter plate 32, fall on the conveyor belt 1 first, and move along with the conveyor belt 1. When the waste rocks on the filter plate 32 are moved to the conveyer belt 1, the waste rocks with larger volume on the filter plate 32 can be placed above the waste rocks with smaller volume on the conveyer belt 1, and the falling of the waste rocks with larger volume is buffered by the waste rocks with smaller volume. In addition, because the waste rocks with small volume can always fall on the conveyor belt 1 first, the waste rocks with small volume are always positioned below the waste rocks with large volume, so that the waste rocks can be screened by the screening plate 4.

The support plate 2 is fixed with a support 21, and the support 21 is positioned below the filter plate 32 and is provided with a leak hole 211. A first connecting rod 22 is fixed on the support 21, a second connecting rod 23 is inserted into the first connecting rod 22, and a buffer spring 24 is connected between the second connecting rod 23 and the first connecting rod 22. The upper end of the second connecting rod 23 is rotatably connected with a rotating shaft 25, and a sliding groove 33 matched with the rotating shaft 25 is formed in the side surface of the buffer plate 3. The first connecting rod 22, the second connecting rod 23, the buffer spring 24, the rotating shaft 25 and the sliding groove 33 are four in number (only 2 are shown in fig. 1, not shown at the rear side of the buffer plate 3). The buffer spring 24 can play a certain role in buffering falling waste rocks. After the waste rocks fall on the filter plates 32, the left end of the buffer plate 3 can be lifted upward to incline the buffer plate 3 and the filter plates 32, so that the waste rocks on the filter plates 32 can roll down onto the conveyor belt 1.

The sieving plate 4 is connected to the supporting plate 2 by a connecting mechanism 5. Specifically, the connecting mechanism 5 includes a hanger plate 51, a disc 52, a hanger bar 53, and a stopper plate 54. The hanger plate 51 is fixed to the right side of the support plate 2, a coupling hole 511 is formed in the hanger plate 51, and the disc 52 is coupled in the coupling hole 511. The hanging rod 53 is inserted into the disc 52, and the lower end of the hanging rod 53 is connected with the sieving plate 4. A stopper plate 54 is fixed to the upper end of the boom 53.

An ejector rod 55 is screwed to the disc 52, and the upper end of the ejector rod 55 abuts against the lower side of the stopper plate 54. The ejector rod 55 is rotated to move the ejector rod 55 upwards, and the ejector rod 55 can jack up the limit plate 54 to move the screening plate 4 upwards, so that the vertical distance between the screening plate 4 and the conveying belt 1 can be adjusted conveniently.

The circular disk 52 has a protruding ring 521 on the circumferential side surface thereof, and the protruding ring 521 is rotatably coupled to the inner wall of the coupling hole 511. The disc 52 can rotate on the hanging plate 51, and the angle between the projection of the screening plate 4 on the conveyor belt 1 and the conveyor belt 1 can be adjusted by rotating the disc 52.

In order to limit the rotation of the disc 52 when the disc 52 does not need to be rotated, a guide frame 56 is fixed on the hanger plate 51, a limit pin 57 is inserted into the guide frame 56, and a plurality of slots 522 matched with the limit pin 57 are arranged on the disc 52 in a circular array. The lower end of the stopper pin 57 is inserted into the insertion groove 522 after passing through the guide frame 56, so that the rotation of the disc 52 can be restricted.

Finally, it should be noted that: the above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and those skilled in the art can make various modifications and changes, and the embodiments of the present invention and features of the embodiments can be arbitrarily combined with each other without conflict. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
