Description

Technical Field

[0001] The invention relates to the technical field of sand and stone separation, and in particular to a sand and stone separation device for building materials. Background Art

[0002] Construction refers to the production activities in the implementation stage of engineering construction, which is the construction process of various buildings. In the process of construction, a large amount of sand is needed as the basic material, and a certain amount of gravel is often mixed in the sand, which affects its use. Therefore, the sand needs to be screened before use to separate the gravel and sand. Traditional separation mostly uses a screen to separate the sand and gravel in the sand and stone mixture.

[0003] A sand and stone separation device for construction disclosed in Chinese patent CN118045760A includes: a shell; a sand and stone multiple screening mechanism, which is connected to the shell; a recovery mechanism; a support swing mechanism; wherein the sand and stone multiple screening mechanism includes: a support box; a fixed frame; a screening assembly, which is arranged on the inner side of the shell and is connected to the support swing mechanism; a central control assembly, which is arranged on the inner side of the support box; a transmission assembly, which is arranged between the screening assembly and the central control assembly; and a dustproof assembly, which is connected to the central control assembly.

[0004] However, compared with the existing technology and the comparative scheme, it can be seen that the sand and stone separation equipment still has the following problems in actual use: In the process of screening sand and gravel, the gravel is easy to get stuck in the screen holes, which is not convenient to clean and will cause the screen to be blocked, affecting the subsequent screening efficiency. Summary of the invention

[0005] The present invention provides a sand and stone separation device for building materials to solve the above technical problems.

[0006] The sand and stone separation device for building materials of the present invention adopts the following technical scheme: comprising a frame, on which a first separation mechanism and a second separation mechanism are arranged; The frame is provided with an inclined plate, the inclined plate is provided with a first material guide plate, a baffle plate and a first connecting frame, the first connecting frame is provided with a slide rail, the first connecting frame is provided with a trigger plate, the trigger plate is rotatably connected to the first connecting frame through an elastic rotating shaft, a trigger bar is provided on the trigger plate, a first inclined surface is provided on a side of the trigger plate away from the first connecting frame, the inclined plate is provided with a connecting shaft, and a gear is provided on the connecting shaft; The first separation mechanism comprises a first separation assembly, and the first separation assembly is provided with a sliding assembly; The first separation assembly includes a first separation grid, a material discharge frame is arranged on one side of the first separation grid, a first sliding shaft and a first elastic member are arranged at the bottom of the first separation grid, a second connecting frame is arranged on the first separation grid, a second inclined surface is arranged on the second connecting frame, a second elastic member is arranged on the second connecting frame, and a sliding groove is opened on the second connecting frame; The sliding assembly comprises a sliding plate, a first tooth groove is provided on one side of the sliding plate, a limited step is provided on the sliding plate, and a second sliding shaft is provided on the sliding plate; The second separation mechanism comprises a second separation grid, on which a slider and a connecting plate are arranged, and on which a second tooth groove is arranged.

[0007] Furthermore, a feed hopper is arranged at the top of the inclined plate, and a second material guide plate is arranged at the bottom of the inclined plate.

[0008] Furthermore, the first sliding shaft is slidably connected to the first connecting frame, and the first elastic member is arranged between the first separation grid and the first connecting frame.

[0009] Furthermore, the second inclined surface is adapted to the first inclined surface.

[0010] Furthermore, the sliding plate is slidably connected to the second connecting frame via a sliding groove.

[0011] Furthermore, the sliding plate meshes with the gear through the first tooth groove.

[0012] Furthermore, the second sliding shaft is slidably connected to the second connecting frame, and the second elastic member is sleeved on the second sliding shaft.

[0013] Furthermore, the second separation grid is adapted to the first separation grid.

[0014] Furthermore, the second separation grid is slidably connected to the slide rail via a slider.

[0015] Furthermore, the connecting plate is meshed with the gear through the second tooth groove, and the connecting plate is transmission-connected with the sliding plate through the gear.

[0016] The beneficial effect of the present invention is that when there is no gravel stuck on the first separation grid or a small amount of gravel is stuck on the first separation grid but does not affect the screening efficiency, the gravel is blocked by the first separation grid and falls along the first separation grid and the feed frame, and the sand passes through the first separation grid and the second separation grid and falls along the second guide plate. When more and more gravel is stuck on the first separation grid, the efficiency of the first separation grid passing the sand is correspondingly reduced, and relatively more sand and stone mixture is accumulated on the first separation grid. The second separation grid quickly moves toward the first separation grid, and the second separation grid and the first separation grid are intertwined with each other to push out the gravel stuck on the first separation grid, thereby ensuring the screening efficiency between sand and gravel.

[0025] like Figure 5 , Figure 7 , Fig. 9 , Fig.13 , Fig.15 and Fig.16 As shown, the sliding assembly 22 includes a sliding plate 221, a first tooth groove 222, a limiting step 223 and a second sliding shaft 224, the second elastic member 217 is arranged between the sliding plate 221 and the second connecting frame 215, the sliding plate 221 is slidably connected to the second connecting frame 215 through the sliding groove 218, a first tooth groove 222 is opened on one side of the sliding plate 221, the sliding plate 221 is meshed with the gear 19 through the first tooth groove 222, a limiting step 223 is arranged on the sliding plate 221, a second sliding shaft 224 is arranged on the sliding plate 221, the second sliding shaft 224 is slidably connected to the second connecting frame 215, and the second elastic member 217 is sleeved on the second sliding shaft 224.

[0026] like Figure 5 , Figure 7 , Fig. 9 , Fig.17 and Fig.18 As shown, the second separation mechanism 3 includes a second separation grid 301, a slider 302, a connecting plate 303 and a second tooth groove 304. The second separation grid 301 is adapted to the first separation grid 211. The second separation grid 301 is provided with a slider 302 and a connecting plate 303. The second separation grid 301 is slidably connected to the slide rail 151 through the slider 302. The connecting plate 303 is provided with a second tooth groove 304. The connecting plate 303 is meshed with the gear 19 through the second tooth groove 304. The connecting plate 303 is transmission-connected to the sliding plate 221 through the gear 19.

[0027] The working process is as follows: S1. When in use, the sand and stone mixture to be separated is added from the feed hopper 12, and the sand and stone mixture falls onto the first separation grid 211 along the inclined plate 11 and the first guide plate 13; S2, when there is no gravel stuck on the first separation grid 211, the gravel is blocked by the first separation grid 211, falls along the first separation grid 211 and the unloading frame 212, and the sand passes through the first separation grid 211 and the second separation grid 301, and falls along the second guide plate 16; S3, when a small amount of crushed stone is stuck on the first separation grid 211, but does not affect the screening efficiency, the crushed stone is also blocked by the first separation grid 211, and falls along the first separation grid 211 and the unloading frame 212, and the sand passes through the first separation grid 211 and the second separation grid 301, and falls along the second guide plate 16; S4. As time goes by, more and more gravels are stuck on the first separation grid 211, and the efficiency of the first separation grid 211 passing sand is correspondingly reduced. Relatively more sand and stone mixtures are accumulated on the first separation grid 211, and the pressure on the first separation grid 211 increases. The first separation grid 211 moves downward along the inclined plate 11, and the first elastic member 214 contracts. The trigger bar 171 clamps the limiting step 223 to limit the sliding plate 221, and the first separation grid 211 moves toward the second separation grid 301. The second elastic member 217 contracts to store force; S5. As more and more gravels are stuck on the first separation grille 211, the pressure on the first separation grille 211 continues to increase, the first separation grille 211 drives the second connecting frame 215 to move, and the second inclined surface 216 on the second connecting frame 215 pushes the trigger plate 17 to rotate through the first inclined surface 172; S6. As the trigger plate 17 rotates, the trigger bar 171 leaves the limiting step 223, releasing the limiting of the sliding plate 221. The second elastic member 217 that contracts and stores force rebounds quickly, driving the sliding plate 221 to quickly move toward the second separation grille 301. The sliding plate 221 drives the connecting plate 303 to move in the opposite direction through the gear 19. The connecting plate 303 drives the second separation grille 301 to move toward the first separation grille 211. The second separation grille 301 and the first separation grille 211 are interlaced with each other, pushing out the gravel stuck on the first separation grille 211. S7, the pushed out gravel falls on the material discharging frame 212 along the second separation grid 301, and then falls down along the material discharging frame 212. After the gravel stuck on the first separation grid 211 is pushed out, the screening efficiency of the sand and gravel mixture by the first separation grid 211 is correspondingly improved; S8. As the screening efficiency of the first separation grid 211 for the sand and gravel mixture is improved, the sand and gravel mixture accumulated on the first separation grid 211 is reduced accordingly, the pressure on the first separation grid 211 is reduced, the first elastic member 214 rebounds, driving the first separation grid 211 to reset, the first separation grid 211 drives the sliding plate 221 to move, the sliding plate 221 drives the connecting plate 303 to slide in the opposite direction and reset through the gear 19, the connecting plate 303 drives the second separation grid 301 to reset, and the sand and gravel mixture continues to be screened.
