DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model discloses a stone crushing and screening device for mining engineering, such as Figure 1-4 As shown, including:

[0022] The crusher 1 has a crushing roller inside, which crushes the crushed stones in the mining project. The inner wall of the crusher 1 is provided with a screening component, which includes:

[0023] A containing unit is arranged in the inner cavity of the stone crusher 1. The containing unit is used to collect and store relatively large pieces of stone. The containing unit comprises a chute 101 and a collecting cabinet 2. A groove is provided on the outer wall of the stone crusher 1. The chute 101 is provided in the groove provided on the outer wall of the stone crusher 1. A slider 201 is fixedly provided on the outer wall of the collecting cabinet 2, and the slider 201 is movably connected in the chute 101. A screening plate 3 is provided on the inner wall of the collecting cabinet 2. After being squeezed and crushed by the crushing roller, the stone pieces fall into the collecting cabinet 2 by gravity. The relatively small stones continue to fall through the screening plate 3, and the larger stones are intercepted by the screening plate 3, so that they are screened, and it is convenient to collect the larger stones, and convenient for subsequent secondary crushing.

[0024] A shaking unit is arranged on the collecting cabinet 2 , and the shaking unit is used to adjust the position state of the screening plate 3 .

[0025] A moving groove 202 is provided on the inner wall of the collecting cabinet 2, and the screening plate 3 is movably engaged in the moving groove 202. The length of the moving groove 202 is greater than the length of the screening plate 3, so that the screening plate 3 has a certain moving space.

[0026] A groove is formed through the outer wall of the screening plate 3 , and the inner wall of the groove formed through the outer wall of the screening plate 3 is rotatably connected to a moving wheel 301 via a rotating shaft, so as to facilitate the movement of the screening plate 3 .

[0027] The shaking unit includes a driving motor 4 and a push rod 402. A fixed plate 203 is fixedly provided on the outer wall of the collection cabinet 2, and the driving motor 4 is fixedly installed on the fixed plate 203. A rotating plate 401 is fixedly provided on the output end of the driving motor 4, and the push rod 402 is rotatably connected to the outer wall of the rotating plate 401 through a pin shaft. The other end of the push rod 402 is rotatably connected to the screening plate 3 through a pin shaft. By starting the driving motor 4, the output end of the driving motor 4 drives the rotating plate 401 to rotate, so that the rotating rotating plate 401 pulls the push rod 402 to move forward, and the screening plate 3 is driven forward by the upward moving push rod 402. When the rotating plate 401 continues to rotate, the push rod 402 is pushed backward, so that the screening plate 3 is pushed backward. The rotating plate 401 is continuously rotated, so that the screening plate 3 moves back and forth multiple times, which is convenient for shaking the stones on the screening plate 3, which is conducive to promoting the falling of small stones and facilitating collection.

[0028] A discharge port 102 is provided on the outer wall of the crusher 1. The bottom of the inner cavity of the discharge port 102 is low in the front and high in the back, so that the crushed stones can slide out of the crusher 1 along the bottom of the inner cavity of the discharge port 102. A containing box 103 is provided in front of the discharge port 102. After the crushed stones slide out of the crusher 1, they fall into the containing box 103, which is convenient for collecting them.

[0029] A fixing block 5 is fixedly provided on the outer wall of the crusher 1. A clamping ring 501 is rotatably connected to the outer wall of the fixing block 5 through a pin shaft, and the clamping ring 501 is clamped at the front end of the slider 201. After the slider 201 is inserted into the slide groove 101, the clamping ring 501 is flipped so that the clamping ring 501 is clamped at the front end of the slider 201, which is convenient for limiting the position of the slider 201 and improving the stability of the position of the collection cabinet 2. The clamping ring 501 is flipped so that the clamping ring 501 is away from the slider 201. At this time, the collection cabinet 2 is pulled forward to separate from the crusher 1, which is convenient for processing larger stones in the crusher 1.

[0030] For those skilled in the art, by setting the connection relationship between the crusher 1, the discharge port 102, the collection cabinet 2 and the screening plate 3, the crushed stones in the mining project are put into the crusher 1, squeezed and crushed by the crushing roller, and then fall onto the screening plate 3 in the collection cabinet 2 by gravity. The smaller stones continue to fall through the screening plate 3, and the larger stones are intercepted by the screening plate 3 and screened, which is convenient for collecting the larger stones and facilitating the subsequent secondary crushing. By setting the screening plate 3, the driving motor 4, the rotating plate 401 and the push rod 402, the screening plate 3 is moved, which is convenient for shaking the stones on the screening plate 3, which is conducive to promoting the falling of small stones and facilitating improving the screening efficiency.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
