DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Embodiment 1

[0045] like Figures 1 to 5 As shown, the present invention provides a concrete slurry screening device, comprising a slurry screening frame 1; a feed box 2 is arranged on the slurry screening frame 1, and a discharge port 21 is arranged at the bottom of the feed box 2; a layer frame 3 is arranged below the discharge port 21; a first screening mechanism 4 and a second screening mechanism 5 are arranged on the layer frame 3 in sequence from top to bottom; a slurry water collecting mechanism 6 is arranged on the side wall of the layer frame 3, and the position of the discharge port 21 corresponds to the position of the slurry water collecting mechanism 6 in the upper and lower directions;

[0046] Among them, the first screening mechanism 4 includes a flip seat 41 rotatably set on the layering frame 3, and the two opposite side walls of the flip seat 41 are both open. A material receiving frame 42 is set on the open side wall of the flip seat 41 at one end close to the discharge port 21, and the position of the discharge port 21 corresponds to the position of the material receiving frame 42 up and down. A screening frame 43 is rotatably set at one end of the flip seat 41 close to the discharge port 21.

[0047] A flip motor 11 is embedded in the side wall of the pulp screening frame 1, and the bottom of the flip seat 41 at one end away from the discharge port 21 is arranged on the output shaft of the flip motor 11, and an adjusting cylinder 44 is arranged on the bottom surface of the end of the flip seat 41 away from the material receiving frame 42, and a frame seat 45 is arranged on the piston rod of the adjusting cylinder 44, and adjusting motors 46 are embedded on the two opposite inner walls of the flip seat 41, and the output shafts of the two adjusting motors 46 are coaxial, and the outer peripheral wall of the screening frame 43 is connected to the output shafts of the two adjusting motors 46, and the end of the screening frame 43 away from the adjusting cylinder 44 is movably clamped in the frame seat 45, and the end of the screening frame 43 close to the discharge port 21 is open, and the end of the screening frame 43 close to the adjusting cylinder 44 is a screen-like structure.

[0048] The first screening mechanism 4 and the second screening mechanism 5 can be selectively used according to needs. When the first screening mechanism 4 is used, the concrete material is put into the feed box 2, and discharged into the first screening mechanism 4 through the discharge port 21 at the bottom of the feed box 2; that is, it falls into the receiving frame 42, and the adjusting cylinder 44 drives the frame seat 45 to contract, so that the frame seat 45 moves in the direction away from the screening frame 43. At this time, the end of the screening frame 43 away from the adjusting cylinder 44 is separated from the frame seat 45; the adjusting motor 46 drives the screening frame 43 to rotate, so that the opening end of the screening frame 43 close to the discharge port 21 faces upward, so that the stones and sand in the receiving frame 42 enter the screening frame 43 again, which is also conducive to ensuring that the stones are not separated. When the screening is performed by shaking and screening with sand, the stones and sand in the screening frame 43 will not scatter; the adjusting motor 46 drives the screening frame 43 to rotate back and forth, so that the stones and sand in the screening frame 43 can be screened out through the end of the screening frame 43 close to the adjusting cylinder 44, and the stones and sand that cannot pass through will stay in the screening frame 43 for collection; when use is completed, start the adjusting motor 46 to drive the screening frame 43 to rotate, so that the screening frame 43 rotates in the direction close to the material receiving frame 42, and at the same time, the adjusting cylinder 44 pushes the frame seat 45 to move in the direction close to the material receiving frame 42, so that the end of the screening frame 43 away from the adjusting cylinder 44 is stuck in the frame seat 45, which is beneficial to maintaining the stability of the screening frame 43.

[0049] When the second screening mechanism 5 is used, the flip motor 11 can be started first to drive the flip seat 41 to flip, so that the material receiving frame 42 rotates in the direction away from the discharge port 21; the discharge port 21 can then be connected to the second screening mechanism 5 through a material conveying pipeline; or stones and sand can be directly added to the second screening mechanism 5, and the second screening mechanism 5 can be used to complete the screening of stones and sand.

[0050] The setting of the slurry water collecting mechanism 6 makes it convenient for the slurry water in the concrete material to flow from the first screening mechanism 4 through the stratification frame 3 to the slurry water collecting mechanism 6 when the stones and sand in the feed box 2 are discharged through the discharge port 21, so as to collect the slurry water in the concrete material.

Inside; the baffle group 53 includes a baffle 1 531; the baffle 1 531 and the baffle 2 532 are spaced in sequence along the length direction of the push rod 52, the screening cylinder 1 55 is located between the baffle 1 531 and the baffle 2 532, and the baffle 2 532 is located between the screening cylinder 1 55 and the screening cylinder 2 56, and the baffle 1 531 is located between the screening cylinder 1 55 and the pushing cylinder 51; the screening cylinder 1 55 and the screening cylinder 2 56 are the same in size and shape, and the length of the screening cylinder 1 55 is the same as the distance between the baffle 1 531 and the baffle 2 532, and two semicircular chucks 54 are evenly distributed on the outer peripheral wall of the end of the push rod 52 away from the pushing cylinder 51, and the diameter of the semicircular chuck 54 is adapted to the inner diameter of the end of the screening cylinder 1 55 close to the screening cylinder 2 56.

[0053] You can choose to use screening barrel 1 55 or screening barrel 2 56 as needed (the screen-like structure at one end of the screening frame 43 close to the adjusting cylinder 44, and the outer peripheral walls of screening barrel 1 55 and screening barrel 2 56 can have different mesh sizes, so as to achieve different screening effects as needed), and use a conveying pipe to connect the discharge port 21 with screening barrel 1 55 or screening barrel 2 56 respectively (that is, to allow stones and sand to flow into screening barrel 1 55 or screening barrel 2 56); or directly add stones and sand into screening barrel 1 55 or screening barrel 2 56 (a feeding cover can be slidably provided on the outer peripheral walls of screening barrel 1 55 and screening barrel 2 56, so as to facilitate opening before feeding and closing after feeding).

[0054] When using the screening cylinder 55, before adding stones and sand into the screening cylinder 55, start the push cylinder 51 to push the baffle set 53 (i.e., baffle 1 531 and baffle 2 532) to move toward the screening cylinder 55 until baffle 2 532 is located in the opening of the screening cylinder 55 at one end close to the push cylinder 51. At this time, the stirring motor 521 and the stirring sheet 522 are both located in the screening cylinder 55. Then, the two semicircular chucks 54 are clamped on the outer peripheral wall of the end of the push rod 52 away from the push cylinder 51, that is, the two semicircular chucks 54 can be blocked in the opening of the screening cylinder 55 away from the push cylinder 51. 1 (at the same time, a bolt can be threadedly connected to the semicircular chuck 54, and the bolt passes through the semicircular chuck 54 and is connected to the open end of the screening cylinder 55). At this time, the openings at both ends of the screening cylinder 55 can be closed, so that the stones and sand in the screening cylinder 55 will not be scattered; starting the stirring motor 521 to drive the stirring blade 522 to rotate, the stones and sand in the screening cylinder 55 can be stirred, so that the stones and sand can be screened through the outer peripheral wall of the screening cylinder 55, and the screened stones and sand can fall to the bottom surface of the screening frame 1 for collection.

[0055] When using the screening cylinder 2 56, before adding stones and sand into the screening cylinder 2 56, start the push cylinder 51 to push the baffle set 53 (i.e., baffle 1 531 and baffle 2 532) to move toward the screening cylinder 2 56 until the baffle 2 532 is located in the opening of the screening cylinder 2 56 at one end close to the screening cylinder 1 55. At this time, the stirring motor 521 and the stirring sheet 522 are both located in the screening cylinder 2 56. Then, the two semicircular chucks 54 are clamped in the push rod 52 away from the push cylinder 51. On the outer peripheral wall at one end, that is, two semicircular chucks 54 can be blocked in the opening of the end of the screening cylinder 2 56 away from the screening cylinder 1 55, so that the openings at both ends of the screening cylinder 2 56 are closed. By starting the stirring motor 521 to drive the stirring plate 522 to rotate, the stones and sand in the screening cylinder 2 56 can be stirred, so that the stones and sand can be screened through the outer peripheral wall of the screening cylinder 2 56, and the screened stones and sand can fall to the bottom surface of the screening frame 1 for collection.

[0056] Two stirring motors 521 may also be arranged at intervals on the push rod 52 (i.e., the two stirring motors 521 are respectively adapted to the positions of the screening drum 1 55 and the screening drum 2 56), so that when the pushing cylinder 51 is started to push the baffle plate 1 531 into the opening of the screening drum 1 55 close to one end of the pushing cylinder 51, the baffle plate 2 532 may be located in the opening of the screening drum 2 56 close to one end of the screening drum 1 55. At this time, the two stirring motors 521 may be respectively located in the screening drum 1 55 and the screening drum 2 56 (such as Figure 7As shown); the opening of the end of the screening drum 2 56 away from the screening drum 1 55 and the opening of the end of the screening drum 1 55 close to the screening drum 2 56 can be blocked by two semicircular chucks 54, so that the openings at both ends of the screening drum 1 55 and the screening drum 2 56 are both in a closed state, and the two stirring motors 521 can be started to stir and screen the stones and sand in the screening drum 1 55 and the screening drum 2 56 at the same time; after the screening is completed, the semicircular chucks 54 with openings at both ends of the screening drum 1 55 and the screening drum 2 56 can be removed, and the pushing cylinder 51 can be started to drive the baffle plate 2 532 to move in the screening drum 2 56 in the direction away from the screening drum 1 55 (at the same time, the baffle plate 1 531 can move in the direction close to the screening drum 2 56), and the stones and sand in the screening drum 2 56 and the screening drum 1 55 can be pushed out by the baffle plate 2 532 and the baffle plate 1 531 respectively.
