Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A sand and gravel separator for a mixing plant, comprising:

[0026] The device body 1 includes a body 11. A stone outlet 12 is provided on one side of the body 11, and a sand outlet 13 is provided on the other side of the body 11. The mechanical components inside the body 11 are existing technologies and can be purchased on the market. They are not considered as technical protection points of this application, and therefore, no further details are provided.

[0027] The bottom of the stone outlet 12 is provided with a conveying mechanism 2, including a support frame 21. A small motor 22 is connected inside one side of the support frame 21. One end of the small motor 22 is connected to a first movable rod 23. A conveyor belt 24 is sleeved on the outer wall of the first movable rod 23. A second movable rod 25 is inserted into one side of the inside of the conveyor belt 24.

[0028] Furthermore, a groove is provided on one side of the inner surface of the support frame 21, and the small motor 22 is connected to one side of the inner wall of the groove provided in the support frame 21, so that one end of the small motor 22 can be limited by the groove provided in the support frame 21.

[0029] Furthermore, one end of the first movable rod 23 is movably connected to one side of the inner surface of the support frame 21, and both ends of the second movable rod 25 are movably connected to both sides of the inner surface of the support frame 21, so that the support frame 21 can limit the two ends of the second movable rod 25.

[0030] Furthermore, the first movable rod 23 and the second movable rod 25 are respectively arranged on both sides inside the conveyor belt 24. The connection relationship between the first movable rod 23 and the second movable rod 25 and the conveyor belt 24 is the same as that between a gear and a rack, so that the first movable rod 23 drives the conveyor belt 24 and the second movable rod 25 to rotate.

[0031] Furthermore, a limiting structure 3 is inserted inside both sides of the support frame 21. The limiting structure 3 includes a threaded rod 31, a support spring 32 is connected inside the threaded rod 31, a limiting block 33 is connected to one end of the support spring 32, a fixing block 34 is sleeved on the outer wall of one end of the threaded rod 31, and a positioning slide plate 35 is connected to one end of the fixing block 34, so as to realize the limiting function between the stone outlet 12 and the support frame 21.

[0032] Furthermore, the positioning slide plate 35 is connected to the inner surface of the support frame 21, and positioning grooves are opened on both sides of the stone outlet 12. The positioning slide plate 35 is inserted into the positioning groove opened in the stone outlet 12. A movable groove is opened on one side of the threaded rod 31, and one end of the support spring 32 is connected to one side of the inner wall of the movable groove opened in the threaded rod 31, so that one end of the support spring 32 is limited by the movable groove opened in the threaded rod 31.

[0033] Furthermore, the support frame 21 has through holes on both sides, the fixing block 34 has through holes on its surface, and the positioning groove of the stone outlet 12 has a threaded groove on one side. One end of the threaded rod 31 passes through the support frame 21 and the fixing block 34 and is rotatably connected to the threaded groove of the stone outlet 12, so as to connect and fix the stone outlet 12 and the support frame 21 through the threaded rod 31.

[0034] Working principle: When pushing the sand and gravel separator of the mixing plant, the small motor 22 is started to drive the first movable rod 23 to rotate. The support frame 21 limits the first movable rod 23 and the second movable rod 25 without affecting their rotation effect. When the first movable rod 23 rotates, it drives the conveyor belt 24 and the second movable rod 25 to rotate at the same time. The conveyor belt 24 is used to transport the sand and gravel and discharge them at a uniform speed.

[0035] When limiting the sand and gravel separator of the mixing plant, one end of the threaded rod 31 is rotated through the through hole 2 of the fixing block 34 and connected to the threaded groove of the stone outlet 12. The limiting block 33 connected to one end of the support spring 32 limits the threaded rod 31, so that it is always located inside the through hole 1 of the support frame 21. The threaded rod 31 is used to connect and fix the fixing block 34 and the stone outlet 12, thereby limiting the support frame 21.
