Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0039] Please refer to Figures 1-14 The present application provides a technical solution: a building construction adjustable screening equipment, comprising a fixed frame 1, a motor 2 arranged on the fixed frame 1, and a storage unit 5 arranged on the upper part of the fixed frame 1 for storing building materials, further comprising:

[0040] A screening unit 4 is arranged on the upper part of the fixed frame 1 for screening sand and stones;

[0041] A transmission unit 3 is arranged on the power output end of the motor 2 and connected with the storage unit 5 and the screening unit 4 for transmitting the kinetic energy of the motor 2;

[0042] An elastic discharge plate 6 is arranged on the fixed frame 1 in an inclined manner and below the screening unit 4 for guiding the falling building materials.

[0043] It should be noted that during operation, the building materials to be screened are placed in the storage unit 5, and then the motor 2 is started. The transmission unit 3 drives the screening unit 4 and the conveying unit inside the storage unit 5 to move, conveying the materials inside the storage unit 5 to the screening unit 4 for screening work. The screened materials fall onto the elastic discharge plate 6, and then the falling materials are collected.

[0044] In an embodiment, the screening unit 4 comprises a top frame 11 arranged on the top of the fixed frame 1, a storage frame 41 arranged inside the top frame 11, a first screen 42 arranged inside the storage frame 41, and a second screen 43 arranged inside the storage frame 41 and below the first screen 42. The storage frame 41 is connected with the transmission unit 3, and a connecting component 46 for controlling the gap size between the first screen 42 and the second screen 43 is arranged between the second screen 43 and the storage frame 41.

[0045] In this way, when the small-sized building materials in the storage frame 41 fall continuously, the building materials in the storage frame 41 are gradually reduced, and when the building materials do not fall, the elastic discharge plate 6 is reset, the connecting component 46 drives the second screen 43 to move, the gap between the first screen 42 and the second screen 43 is enlarged, then the larger building materials fall from the gap between the first screen 42 and the second screen 43 and fall on the elastic discharge plate 6, and when the falling building materials do not fall again, the connecting component 46 adjusts the gap between the first screen 42 and the second screen 43 again, so that the size of the building materials can be automatically controlled, and the building materials of different sizes can be screened.

[0046] In an embodiment, the connecting component 46 comprises a connecting block 461 arranged at the lower part of the storage frame 41, a fixed shaft 462 arranged on the connecting block 461, and a gear 463 sleeved on the fixed shaft 462, wherein the gear 463 is located below the second screen 43, and a push plate 464 is arranged on the gear 463.

[0047] In this way, when the building materials do not fall from the inside of the storage frame 41, the elastic discharge plate 6 is no longer impacted by the building materials and returns to the original position, and then the gear 463 rotates when the storage frame 41 moves left and right, thereby driving the second screen 43 to move a displacement, and then the gap between the first screen 42 and the second screen 43 is enlarged.

[0048] In an embodiment, the second screen 43 is provided with a moving plate 432 near one side of the connecting block 461, the storage frame 41 is provided with a moving groove 411 corresponding to the position of the moving plate 432, the lower part of the moving plate 432 is provided with a limiting block 433, and the push plate 464 is connected with the limiting block 433.

[0050] In this way, the gear 463 rotates to drive the push plate 464 to rotate, and when the push plate 464 rotates to contact the limiting block 433 at the lower part of the moving plate 432, the moving plate 432 is driven to move, thereby moving the second screen 43 below the first screen 42, and the sliding block 431 slides in the guide groove 451, so that the movement state of the second screen 43 can be limited by the sliding block 431, and the second screen 43 moves more stably.

[0051] In an embodiment, the storage frame 41 is provided with a guide rod 44 near the side wall of the top frame 11, the top frame 11 is provided with a limiting slot 110 for the sliding of the guide rod 44 at the position corresponding to the guide rod 44, and the inside of the top frame 11 is provided with a guide wheel 12 corresponding to the bottom wall of the storage frame 41.

[0052] In this way, the guide rod 44 moves in the inside of the limiting slot 110, which can make the storage frame 41 move more smoothly in the inside of the top frame 11, thereby improving the screening efficiency of the building materials, the guide wheel 12 can support the moving storage frame 41, reduce the friction between the storage frame 41 and the top frame 11, and thereby improve the service life of the storage frame 41.

[0055] In an embodiment, the adjusting device 63 includes a swing plate 631 provided on the lower part of the elastic material discharging plate 6, a traction rope 632 provided on the upper part of the swing plate 631, a lifting rod 634 provided on the upper part of the traction rope 632, a guide plate 633 provided on the fixed frame 1, and a lifting plate 636 provided on the upper part of the lifting rod 634, the lifting rod 634 is provided through the lifting plate 636, the elastic member 635 is sleeved between the guide plate 633 and the lifting plate 636, the lifting plate 636 is provided with a rack 637 corresponding to the position of the gear 463, the rack 637 is threadedly connected with the gear 463, and the elastic member 635 is made of a spring or an elastic pad.

[0056] In this way, when the elastic material plate 6 swings up and down, the lifting rod 634 is driven to move up and down by the traction rope 632, and then the lifting plate 636 extrudes the elastic member 635. When the material no longer falls, the elastic material plate 6 returns to the original position, and then the elastic member 635 drives the lifting rod 634 to move upwards, and then the lifting plate 636 moves upwards to return to the original position. When the lifting plate 636 returns to the original position, the rack 637 is just engaged with the gear 463. When the transmission unit 3 drives the material storage frame 41 to swing left and right, the rack 637 is engaged with the gear 463 to drive the gear 463 to rotate one circle, and then the actuating plate 464 is in contact with the limiting block 433 to drive the moving plate 432 to move one unit of displacement, so that the size of the gap between the second screen 43 and the first screen 42 is increased by one size.

[0057] In an embodiment, the transmission unit 3 includes a first pulley 31 arranged at the power output end of the motor 2, a rotating shaft 34 arranged at the upper part of the fixed frame 1, a second pulley 33 sleeved on the rotating shaft 34, and a first belt 32 sleeved between the first pulley 31 and the second pulley 33.
