Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a sand screening machine for construction engineering construction. Background Technique

[0002] Construction engineering refers to the engineering entity formed by the construction of various housing buildings and their ancillary facilities and the installation of pipelines and equipment supporting them. During the construction of housing buildings, concrete is required, and the composition of concrete includes sand. This sand needs to be screened before being mixed with materials such as cement to remove large-grained sand and gravel to avoid affecting the quality of construction.

[0003] During the screening process of the existing sand screening machine for screening sand, small-grained sand will pass through the sieve holes, and large-grained sand and gravel will remain on the sieve mesh. Since the sieve mesh is generally fixed on the sand screening machine, the cleaning of the sand and gravel remaining on the sieve mesh requires manual operation. Due to the limitation of the fixed position of the sieve mesh, the cleaning of the sand and gravel is very inconvenient.

[0004] Therefore, we make improvements and propose a sand screening machine for construction engineering construction. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A sand screening machine for construction engineering construction of the utility model includes a frame body. A sieve mesh is installed inside the frame body. One side of the frame body is penetrated, and a partition board is arranged at the penetrated part. A support plate is slidably arranged at the bottom of the sieve mesh inside the frame body. A threaded rod is rotatably arranged inside the frame body, and both the support plate and the partition board are threadedly connected to the threaded rod; Elastic guide plates are respectively fixedly connected to both sides of the support plate. The elastic guide plates are slidably connected to the inner wall of the frame body, and sand outlets are respectively opened on both sides of the frame body; A guide frame is also arranged on one side of the frame body.

[0007] As a preferred technical solution of the utility model, support blocks are respectively fixedly installed on the inner walls of the four corners of the frame body, and the sieve mesh is fixedly installed on the top surfaces of the support blocks.

[0020] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0021] Embodiment: As Figures 1 to 4 shown, a sand screening machine for construction engineering construction according to the present utility model includes a frame body 1. The top surface of the frame body 1 is penetrated to facilitate the feeding of the sand to be screened into the frame body 1. A screen 2 is installed in the frame body 1. The fed sand enters the frame body 1, and the sand can be screened through the screen 2, so that the small-particle sand passes through the screen holes on the screen 2, and the large-particle sand and gravel remain on the screen 2. Support blocks 10 are respectively and fixedly installed on the inner walls of the four corners of the frame body 1, and the screen 2 is fixedly installed on the top surfaces of the support blocks 10. The support blocks 10 can support the screen 2.

[0022] One side of the frame body 1 is penetrated, and a partition plate 9 is provided at the penetrated part. During screening, the partition plate 9 fits against the penetrated part to close and block the penetrated part, so as to facilitate the screening of the sand. When it is necessary to clean the sand and gravel on the screen 2, the partition plate 9 needs to be moved to open the penetrated part to facilitate the discharge of the sand and gravel from the penetrated part.

[0023] A support plate 5 is slidably arranged inside the frame body 1 and at the bottom of the screen 2. The support plate 5 can support the screen 2, and the top surface of the support plate 5 is slidably connected to the bottom surface of the screen 2. A threaded rod 12 is rotatably arranged inside the frame body 1, and both the support plate 5 and the partition plate 9 are threadedly connected to the threaded rod 12. The movement of the support plate 5 and the partition plate 9 is realized by the rotation of the threaded rod 12. Downward convex blocks (not shown in the figure) are arranged in the middle of the bottom surfaces of the support plate 5 and the partition plate 9, and the convex blocks are threadedly connected to the threaded rod 12. When the threaded rod 12 rotates, the convex blocks will drive the support plate 5 and the partition plate 9 to move along the threaded rod 12 in the same direction.

[0024] A motor 3 is fixedly installed on one side of the frame body 1, and the output end of the motor 3 is fixedly connected to one end of the threaded rod 12. The motor 3 is a forward and reverse motor, and a conventional controller (not shown in the figure) for controlling the start and stop of the motor 3 is provided on the frame body 1. The motor 3 is operated through the controller to drive the threaded rod 12 to rotate.

[0025] An elastic baffle 7 is arranged on the frame body 1 and at the top of the threaded rod 12. One end of the elastic baffle 7 is fixedly connected to the side wall of the frame body 1, and the other end is fixedly connected to the side surface of the partition plate 9. The two sides of the elastic baffle 7 are respectively slidably connected to the inner wall of the frame body 1. The elastic baffle 7 can shield and protect the threaded rod 12, and can expand and contract accordingly as the partition plate 9 moves.

[0026] On both sides of the support plate 5, elastic guide plates 6 are fixedly connected respectively. The elastic guide plates 6 are slidably connected to the inner wall of the frame body 1, and sand outlets 4 are respectively formed on both sides of the frame body 1. When the support plate 5 moves, it will drive the elastic guide plate 6 on one side to stretch and the elastic guide plate 6 on the other side to contract. By providing the elastic guide plates 6, the sand sifted from the sieve mesh 2 can be discharged from the elastic guide plates 6 to the sand outlets 4. A container for receiving sand can be placed at the sand outlets 4. The materials of the elastic guide plates 6 and the elastic baffle plates 7 are both wear-resistant rubber materials.

[0027] The sides of the elastic guide plates 6 close to the partition plate 9 are connected to each other and seal the through part of the frame body 1. And the connection part between the two is fixedly connected to the inner bottom surface of the frame body 1, and a through hole (not shown in the figure) for the threaded rod 12 to pass through is formed at the connection part between the two. And the side surfaces of the elastic guide plates 6 facing the sand outlets 4 are all inclined surfaces. One side of the elastic guide plates 6 is fixed on the inner wall of the frame body 1, and the other sides are connected to each other, so as to prevent sand from falling into the space between the frame body 1 and the elastic guide plates 6 after the partition plate 9 is removed.

[0028] A guide frame 11 is also provided on one side of the frame body 1. The two sides of the guide frame 11 are inclined, and support feet are fixedly arranged at the bottom ends of the inclined surfaces on both sides of the guide frame 11. A base 8 is fixedly arranged at the bottom end of the frame body 1, and the bottom surfaces of the support feet and the bottom surface of the base 8 are located on the same horizontal plane.

[0029] When it is necessary to clean the sand and gravel on the sieve mesh 2, the partition plate 9 can be driven to move by rotating the threaded rod 12, so that the through part of the frame body 1 is opened. Then the guide frame 11 is placed between the through part of the partition plate 9 and the frame body 1, so that the two ends of the guide frame 11 are respectively attached to the frame body 1 and the partition plate 9. Then, by using tools, such as an existing push plate, the sand and gravel on the sieve mesh 2 are pushed to the through part, so that the sand and gravel are discharged along the guide frame 11. It should be noted that when discharging the sand and gravel, it is necessary to block the already screened sand by existing technologies to prevent the two from being mixed. By providing the guide frame 11, the efficiency of cleaning the sand and gravel can be greatly improved.

[0030] During operation, the sand passing through the sieve mesh 2 will be discharged to the sand outlets 4 along the elastic guide plates 6, while the large-particle sand and gravel remain on the surface of the sieve mesh 2. When it is necessary to clean these sand and gravel, the support plate 5 and the partition plate 9 can be driven to move together by rotating the threaded rod 12. The support plate 5 plays a supporting role, and the movement of the partition plate 9 makes one end of the frame body 1 open. At this time, the guide frame 11 is placed at the open place, so as to facilitate pushing the sand and gravel on the sieve mesh 2 from the open place to the guide frame 11 for discharging, thereby reducing the burden of the staff cleaning the sand and gravel and improving the cleaning efficiency.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
