Description

Technical Field

[0001] This application relates to the field of manufactured sand processing technology, specifically to an adjustable screening device for manufactured sand. Background Technology

[0002] Manufactured sand refers to sand produced by sand making machines and other auxiliary equipment. The finished product is more regular in shape and can be processed into sand of different shapes and sizes according to different process requirements, better meeting daily needs. In recent years, with the rapid development of various construction projects in China, investment in infrastructure such as highways and railways has increased significantly, creating an urgent need for large quantities of sand and gravel. Due to the increasing scarcity of natural sand resources and the serious environmental damage caused by natural sand mining, manufactured sand has developed rapidly. During the production process, manufactured sand produces sand particles of different specifications. These different specifications have different functions in specific application processes, therefore, it is necessary to screen and store the different specifications separately.

[0003] In the existing technology, when screening manufactured sand of different particle sizes, it is necessary to disassemble and replace the screen in the screening device, which is not convenient to operate. Moreover, when the screened large-particle sand fills the screen, it is not easy to clean the sand.

[0004] Therefore, we hope to provide an adjustable screening device for manufactured sand. Utility Model Content

[0005] This embodiment provides an adjustable screening device for manufactured sand, which solves the problem that when screening manufactured sand of different particle sizes, it is necessary to disassemble and replace the screening screen inside the screening device, which is not convenient to operate. Moreover, when the screened large-particle sand fills the screening screen, it is not easy to clean out the sand.

[0006] According to one aspect of this application, an adjustable screening device for manufactured sand is provided, including a screening cylinder, with support plates fixed to the bottom of both ends of the screening cylinder, and a vibration structure provided on the support plates. The adjustable screening device for manufactured sand further includes: A screening structure, wherein the screening structure is fixed at the middle position of the screening cylinder; A support structure is symmetrically fixed at the middle position of the two side walls of the screening cylinder.

[0007] Furthermore, a feed hopper is fixed at the top of the screening cylinder, and a discharge port is provided at the bottom of the screening cylinder.

[0008] Furthermore, the vibration structure includes a base plate, a limiting rod, a buffer spring, and a vibration motor, wherein the vibration motor is fixed to the side wall of the support plate at one end of the screening cylinder.

[0009] Furthermore, the bottom of the support plates at both ends of the bottom of the screening cylinder is provided with a base plate, and multiple sets of limiting rods and buffer springs are horizontally fixed on the top of the base plate. The buffer springs are sleeved on the outside of the limiting rods, and the tops of the limiting rods and buffer springs are fixed to the bottom of the corresponding support plates.

[0010] Furthermore, the screening structure includes a drive motor, a rotating shaft, a first screening screen, and a second screening screen, with the drive motor fixed to the side wall of the screening cylinder at the top of the vibrating motor.

[0011] Furthermore, the output end of the drive motor is fixed with a rotating shaft passing through the side wall of the screening cylinder, and the other end of the rotating shaft is rotatably connected to the other side wall of the screening cylinder.

[0012] Furthermore, a first screening screen is symmetrically fixed to the left and right side walls of the rotating shaft, and a second screening screen is symmetrically fixed to the top and bottom of the rotating shaft. The aperture of the first screening screen is smaller than that of the second screening screen.

[0013] Furthermore, both the first and second screening meshes are configured in an arc shape, and the ends of the first and second screening meshes away from the rotating shaft overlap with the inside of the screening cylinder.

[0014] Furthermore, the support structure includes an L-shaped plate, a threaded rod, a mounting plate, and a bearing plate. The L-shaped plate is symmetrically fixed at the middle position of both side walls of the screening cylinder, and the bottom end of the L-shaped plate is threadedly connected to the threaded rod.

[0015] Furthermore, one end of the threaded rod passes through the L-shaped plate and is rotatably connected to the mounting plate, and a bearing plate is fixed to the end of the mounting plate away from the threaded rod. The other end of the bearing plate passes through the side wall of the screening cylinder and is slidably connected to the side wall of the screening cylinder.

[0016] The advantages of this application are: 1. By setting a screening structure inside the screening cylinder, screening screen one and screening screen two in the screening structure are fixed on the rotating shaft. The drive motor in the screening structure drives the rotating shaft to rotate, which can drive screening screen one and screening screen two to rotate. Thus, the corresponding screening screen can be rotated to a position parallel to the ground according to the particle size of the manufactured sand to be screened. The screening screen is supported by the support structure, so there is no need to disassemble or replace the screening screen. The adjustment is convenient and the practicality of the screening device is improved.

[0017] 2. A discharge port is set at the bottom of the screening cylinder. When the screening screen is filled with large-diameter sand and gravel, the threaded rods in the support structure are rotated to separate the bearing plate from the screening screen. Then, the drive motor drives the rotating shaft to rotate, causing the screening screen to tilt, so that the sand and gravel accumulated on the screening screen can fall off and be discharged from the discharge port.

[0028] The top of the screening cylinder 1 is fixed with a feed hopper 2, and the bottom of the screening cylinder 1 is provided with a discharge port 7.

[0029] The vibration structure 4 includes a base plate 401, a limiting rod 402, a buffer spring 403, and a vibration motor 404. The vibration motor 404 is fixed on the side wall of the support plate 3 at one end of the screening cylinder 1.

[0030] The bottom of the support plates 3 at both ends of the bottom of the screening cylinder 1 is provided with a base plate 401. Multiple sets of limiting rods 402 and buffer springs 403 are horizontally fixed on the top of the base plate 401. The buffer springs 403 are sleeved on the outside of the limiting rods 402. The top ends of the limiting rods 402 and the buffer springs 403 are fixed to the bottom of the corresponding support plates 3.

[0031] The screening structure 5 includes a drive motor 501, a rotating shaft 502, a first screening screen 503, and a second screening screen 504. The drive motor 501 is fixed on the side wall of the screening cylinder 1 at the top of the vibrating motor 404.

[0032] The output end of the drive motor 501 is fixed with a rotating shaft 502 through the side wall of the screening cylinder 1, and the other end of the rotating shaft 502 is rotatably connected to the other side wall of the screening cylinder 1.

[0033] Screening mesh 1 503 is symmetrically fixed on the left and right side walls of the rotating shaft 502, and screening mesh 2 504 is symmetrically fixed on the top and bottom of the rotating shaft 502. The aperture of screening mesh 1 503 is smaller than that of screening mesh 2 504.

[0034] Both the first screening mesh 503 and the second screening mesh 504 are arc-shaped, and the ends of the first screening mesh 503 and the second screening mesh 504 away from the rotating shaft 502 overlap with the inside of the screening cylinder 1.

[0035] The support structure 6 includes an L-shaped plate 601, a threaded rod 602, a mounting plate 603, and a bearing plate 604. The L-shaped plate 601 is symmetrically fixed in the middle of the two side walls of the screening cylinder 1, and the bottom end of the L-shaped plate 601 is threadedly connected to the threaded rod 602.

Depending on the particle size of the manufactured sand to be screened, the corresponding screening screen is rotated to a position parallel to the ground. Then, the threaded rod 602 in the support structure 6 is rotated, pushing the mounting plate 603 and the bearing plate 604 towards one side of the screening cylinder 1, so that the bearing plate 604 supports the screening screen. Finally, the sand and gravel to be screened are fed into the feed hopper 2. The vibration motor 404 is started, which drives the screening cylinder 1 to vibrate, causing the sand and gravel to pass through the screening screen. The screened sand and gravel fall through the screening screen and are discharged from the discharge port 7. Screening screen 1 503 and screening screen 2 504 are set in an arc shape, which can improve the screening efficiency of sand and gravel. When the screening screen in the screening structure 5 is filled with large-diameter sand and gravel, the threaded rod 602 in the support structure 6 is rotated to separate the bearing plate 604 from the screening screen. Then, the drive motor 501 drives the rotating shaft 502 to rotate, causing the screening screen to tilt, so that the sand and gravel accumulated on the screening screen can fall off and be discharged from the discharge port 7.
