[0029] As a further implementation of the present invention, the inner side of the feed hopper 1 is hollow, the bottom end of the feed hopper 1 is fixedly connected to the top end of the feed box 21, and the inner side of the feed hopper 1 is connected to the inside of the feed port 23 opened in the feed box 21. This design allows concrete sand and gravel to flow smoothly from the hollow inner side of the feed hopper 1 into the feed port 23, thereby achieving rapid introduction and effective diversion of materials and improving the working efficiency of the separator;
[0030] As a further implementation of this scheme, an axial hole is opened on the inner side of the main shaft of the feed box 21 near the drive motor 22, and the main shaft of the drive motor 22 rotates inside the feed box 21. A sealing ring is fixed inside the axial hole of the feed box 21, and the main shaft of the drive motor 22 fits with the sealing ring of the axial hole of the feed box 21. The partition 24 is composed of two inclined plates, and the water outlet 25 runs through the interior of the partition 24. The partition 24 and the secondary screening assembly 3 are on the same vertical line, which ensures the rotation sealing of the main shaft drive motor 22 and prevents material leakage. At the same time, the inclined plate design of the partition 24 and the setting of the water outlet 25 enhance the flow guidance of the mud, making the separation process smoother;
[0031] As a further implementation of the present scheme, the limiting ring 45 is in the shape of a ring, and the limiting ring 45 is fixed to the outer side of the front end and the outer side of the rear end of the screen drum 43, and the limiting ring 45 is rotatably connected to the inner side of the feed box 21 and the discharge box 26, and the screen drum 43 is inside the feed box 21 and the discharge box 26, and the outer side of the screen drum 43 is flush with the inside of the feed port 23 opened in the feed box 21, and the end of the main shaft of the drive motor 22 is fixedly connected to the rear end of the shaft roller 41, which ensures the effective operation of the screen drum 43 of the screening device. At the same time, the design of the screen drum 43 being flush with the inside of the feed port 23 helps to evenly distribute the material and improve the screening efficiency;
[0032] As a further implementation of the present invention, the shaft roller 41 is rotatably connected to the inner side of the feed box 21 and the discharge box 26, the first spiral blade 42 is located inside the feed port 23 opened in the feed box 21, and the first spiral blade 42 is located inside the discharge port 27 opened in the discharge box 26. This layout helps to achieve continuous flow and screening of materials inside the separator, thereby improving separation efficiency and quality.
[0033] As a further implementation of the present invention, through holes are provided on the inner side of the screen drum 43 and the inner side of the screen mesh 31. The diameter of the through hole of the screen drum 43 is twice the diameter of the through hole of the screen mesh 31. The second triangular plate 46 has the same shape as the first triangular plate 34. The shape of the second triangular plate 46 is a triangle. The through hole design of the screen drum 43 and the screen mesh 31 enables the slurry to be screened at different stages. The larger through hole diameter of the screen drum 43 is conducive to preliminary screening, while the smaller through hole diameter of the screen mesh 31 achieves finer screening.
[0034] As a further implementation scheme of the present scheme, ear seats are fixed to the front end of the feed box 21 and the rear end of the discharge box 26, the bottom ends of the spring telescopic rods 33 are fixed to the ear seats of the feed box 21 and the discharge box 26, the front end of the screen 31 fits with the rear end of the discharge box 26, and the rear end of the screen 31 fits with the front end of the feed box 21. There are four side blocks 32, which ensure the stability of the equipment during operation. The number and layout of the side blocks 32 help to evenly disperse the vibration force, making the screening process more uniform and effective.
[0035] Working process: When the quality of concrete sand and gravel screening is controlled and the screening speed is ensured, concrete sand and gravel are poured from the inside of the feed hopper 1, and the concrete sand and gravel enter the inside of the feed port 23 opened by the feed box 21, and the main shaft of the driving motor 22 is started to drive the shaft roller 41 to rotate, and the shaft roller 41 is connected to the inside of the feed box 21 and the discharge box 26, and the rotation of the shaft roller 41 drives the first spiral blade 42 to rotate, and the first spiral blade 42 transports the concrete sand and gravel inside the feed port 23, and the concrete sand and gravel are transported to the inside of the screen drum 43, and the concrete is screened by the screen drum 43. The sand and gravel slurry is screened and flows out from the through hole inside the screen drum 43. The through hole diameter of the screen drum 43 is slightly larger. The mud screened by the screen drum 43 is mixed with some small-diameter sand and gravel. The sand and gravel are inside the screen drum 43. When the first spiral blade 42 rotates, the sand and gravel are transported to the inside of the discharge port 27 opened in the discharge box 26 through the first spiral blade 42, so that the large particles of sand and gravel are recovered. The mud flowing out of the screen drum 43 falls into the inside of the screen 31. When the screen drum 43 rotates, it drives the second spiral blade 44 to rotate. The slurry inside the screen 31 is transported. At the same time, when the screen drum 43 rotates, the second triangular plate 46 is driven to rotate. After the second triangular plate 46 contacts the first triangular plate 34, the first triangular plate 34 moves downward through the extrusion of the second triangular plate 46. The first triangular plate 34 drives the screen 31 and the edge block 32 to move downward, and the spring telescopic rod 33 elastically contracts. The spring telescopic rod 33 maintains elastic extension. When the second triangular plate 46 moves away from the first triangular plate 34, the screen 31 is quickly reset under the elastic force of the spring telescopic rod 33. In this process, The screen 31 vibrates, thereby filtering the mud again, and the mud flows out from the through holes inside the screen 31. The diameter of the through holes of the screen 31 is small, so as to achieve the effect of re-screening. The mud and sand remaining in the screen 31 are transported by the second spiral blade 44. There is a partial distance between the front end of the screen 31 and the rear end of the discharge box 26. The mud and sand flow out from the gap at the front end of the partition 24, and at the same time, part of the mud flows out from the water outlet 25 opened in the partition 24. The device uses a multi-stage screening work process to ensure the quality of concrete sand and gravel screening and the screening speed.
[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
