Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a sand screening device for building construction. Background Technology

[0002] In the field of construction engineering, sand screening is a core process for ensuring the quality of sand and meeting project requirements. Its importance is self-evident, as it directly affects the performance of building materials such as concrete, as well as the overall stability and durability of buildings.

[0003] However, existing sand screening devices have certain design limitations. These devices generally use an inclined vibrating screen with a hopper at the top. Because the hopper is located at a high position, workers need to transport the sand to this height for unloading during actual operation. This process is not only physically demanding, causing workers to easily become fatigued, but also significantly reduces work efficiency as fatigue accumulates. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a sand screening device for building construction.

[0005] Technical Solution: A sand screening device for construction includes a base plate, spring telescopic rods, mounting frames, a vibrating motor, a screen, and columns. Spring telescopic rods are symmetrically fixed to the top left and right sides of the base plate. Mounting frames are fixedly connected between the tops of two spring telescopic rods on the same side in the left-right direction. A vibrating motor is installed in the middle of each of the two mounting frames. A screen is detachably fixed between the tops of the two mounting frames. Columns are symmetrically fixed to the rear left and right sides of the top of the base plate. The device also includes a transfer component, a feeding component, and a lifting component. A transfer component for transferring sand is installed between the two columns. A feeding component for feeding sand to the top of the screen is installed between the middle of the two columns. A lifting component for lifting the transfer component to the height of the feeding component is installed between the tops of the two columns.

[0006] Furthermore, it is particularly preferred that the transfer assembly includes a transfer bucket, guide rods, L-shaped connecting blocks, a return spring, and a closing plate. The transfer bucket is slidably disposed between the two columns. An opening is provided on the lower side of the front panel of the transfer bucket. Guide rods are fixedly connected to both sides of the transfer bucket. L-shaped connecting blocks are slidably connected to both guide rods. A return spring is connected between the L-shaped connecting blocks and the adjacent guide rods. A closing plate is fixedly connected between the lower parts of the two L-shaped connecting blocks. The closing plate can close the opening.

[0007] Furthermore, it is particularly preferred that the feeding assembly includes a support, a feeding hopper, and a guide trough, with the support fixedly connected to the middle of each of the two columns, the feeding hopper fixedly connected between the front sides of the two supports, and the guide trough fixedly connected to the rear top of the feeding hopper.

[0008] Furthermore, it is particularly preferred that the lifting assembly includes a horizontal plate, mounting bases, connecting shafts, winding wheels, cables, and a dual-axis motor. A horizontal plate is fixedly connected between the tops of the two columns. Mounting bases are symmetrically fixedly connected to the tops of the horizontal plate. A connecting shaft is rotatably connected to each of the two mounting bases. Winding wheels are fixedly connected to the ends of the two connecting shafts that are far apart from each other. Cables are fixedly wound on the winding wheels. The lower ends of the two cables are fixedly connected to the left and right sides of the top of the transfer bucket, respectively. A dual-axis motor is installed in the middle of the top of the horizontal plate. The two output shafts of the dual-axis motor are fixedly connected to the ends of the two connecting shafts, respectively.

[0009] In addition, it is particularly preferred that the screen also includes baffles, with baffles detachably fixed to the top of the screen in a symmetrical manner on both sides.

[0010] Furthermore, it is particularly preferred that the plate also includes a fixing rod and an inclined plate, with two fixing rods fixedly connected at intervals on the top left side of the base plate, and an inclined plate fixedly connected between the tops of the two fixing rods, the bottom right side of the inclined plate being fixedly connected to the top right side of the base plate.

[0011] The beneficial effects achieved by this utility model are as follows: This utility model changes the traditional method of transporting sand to a high place for unloading. Workers only need to shovel the sand into the low-level transfer bucket, and the transfer bucket is lifted by a motor and other components to achieve automatic unloading, which greatly saves physical strength and effectively avoids workers from getting tired quickly due to laborious handling, thereby significantly improving the work efficiency of sand screening operations.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Example: A sand screening device for building construction, such as Figures 1-4 As shown, the system includes a base plate 1, spring telescopic rods 2, mounting frames 21, a vibrating motor 22, a screen 23, and columns 31. Spring telescopic rods 2 are symmetrically welded and fixed to the top left and right sides of the base plate 1. Mounting frames 21 are welded and fixed between the tops of two spring telescopic rods 2 on the same side in the left-right direction. Vibrating motors 22 are installed in the middle of the two mounting frames. The screen 23 is detachably fixed between the tops of the two mounting frames 21 by bolts. Columns 31 are symmetrically welded and fixed to the rear left and right sides of the top of the base plate 1. The system also includes a transfer assembly, a feeding assembly, and a lifting assembly. A transfer assembly for transferring sand is installed between the two columns 31. A feeding assembly for feeding sand to the top of the screen 23 is installed between the middle of the two columns 31. A lifting assembly for lifting the transfer assembly to the height of the feeding assembly is installed between the tops of the two columns 31.

[0019] like Figure 2 and Figure 3 As shown, the transfer assembly includes a transfer bucket 32, guide rods 34, L-shaped connecting blocks 35, a return spring 36, and a sealing plate 37. The transfer bucket 32 ​​is slidably arranged between two columns 31. An opening 33 is provided on the lower side of the front panel of the transfer bucket 32. The bottom panel of the transfer bucket 32 ​​is arranged with the back higher than the front, so that the sand in the transfer bucket 32 ​​can slide out through the opening 33. Guide rods 34 are welded and fixed on both sides of the transfer bucket 32. L-shaped connecting blocks 35 are slidably connected to both guide rods 34. A return spring 36 is connected between the L-shaped connecting blocks 35 and the adjacent guide rods 34. A sealing plate 37 is fixed between the lower parts of the two L-shaped connecting blocks 35 by screws. The sealing plate 37 can close the opening 33.

[0020] like Figure 1 and Figure 4 As shown, the feeding assembly includes a bracket 51, a feeding hopper 52, and a guide trough 53. The bracket 51 is welded and fixed to the middle of the two columns 31. The feeding hopper 52 is fixed between the front sides of the two brackets 51 by bolts. The guide trough 53 is fixed to the rear top of the feeding hopper 52 by screws.

[0021] like Figure 2As shown, the lifting assembly includes a horizontal plate 41, a mounting base 42, a connecting shaft 43, a winding wheel 44, a cable 45, and a dual-axis motor 46. The horizontal plate 41 is fixed between the tops of the two columns 31 by screws. The mounting bases 42 are symmetrically welded to the top of the horizontal plate 41. The connecting shafts 43 are rotatably connected to both mounting bases 42. The ends of the two connecting shafts 43 that are far apart from each other are fixed with winding wheels 44 by screws. The cables 45 are fixedly wound on the winding wheels 44. The lower ends of the two cables 45 are fixedly connected to the left and right sides of the top of the transfer bucket 32, respectively. The dual-axis motor 46 is installed in the middle of the top of the horizontal plate 41. The two output shafts of the dual-axis motor 46 are fixedly connected to the ends of the two connecting shafts 43, respectively.

[0022] In operation, workers first shovel sand into the transfer bucket 32. Once the bucket is full, they start the dual-shaft motor 46. The two output shafts of the motor rotate synchronously, which in turn drives the two winding wheels 44 to simultaneously wind the cable 45 via the two connecting shafts 43. As the cable 45 winds up, it lifts the transfer bucket 32 ​​along the column 31 until the bottom of the opening 33 on the front of the bucket 32 ​​is flush with the rear bottom of the guide chute 53. As the bucket 32 ​​moves upward, the sealing plate 37 also moves upward and then contacts the guide chute 53. As the bucket 32 ​​continues to move upward, the sealing plate 37 is limited by the guide chute 53. As the transfer hopper 32 moves upward, the sealing plate 37 moves downward relative to the transfer hopper 32, and the L-shaped connecting block 35 also moves downward relative to the transfer hopper 32. At this time, the return spring 36 is compressed, and the sealing plate 37 gradually releases the seal on the opening 33. The sand in the transfer hopper 32 then flows out through the gradually opening opening 33 and flows into the discharge hopper 52 under the guidance of the guide chute 53. It then falls evenly from the bottom of the discharge hopper 52 onto the screen 23. The workers start the two vibrating motors 22 to screen the sand. Since the workers only need to shovel the sand and pour it into the lower transfer hopper 32, a better labor-saving effect is achieved, thereby improving work efficiency.

[0023] like Figure 1 As shown, it also includes baffles 6, and the top of the screen 23 is symmetrically and detachably fixed with baffles 6.

[0024] By setting baffles 6, the left and right sides of the screen 23 can be blocked to prevent sand from falling from the left and right sides.

[0025] like Figure 1 and Figure 2 As shown, it also includes a fixing rod 71 and an inclined plate 72. Two fixing rods 71 ​​are welded and fixed at intervals on the top left side of the base plate 1. An inclined plate 72 is welded and fixed between the tops of the two fixing rods 71. The bottom right side of the inclined plate 72 is fixedly connected to the top right side of the base plate 1 by screws.

[0026] By setting a fixed rod 71 and an inclined plate 72, the sand screened out from the screen 23 will fall down onto the inclined plate 72, and then roll down along the inclined plate 72 to the right side of the bottom plate 1, which makes it convenient for workers to take the screened sand.

[0027] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
