Description

Technical Field

[0001] The present application relates to the technical field of steel processing equipment, and in particular to a vibrating sand screening machine for steel preparation. Background Art

[0002] The sand screening machine imitates the working principle of manually screening sand with an inclined screen to separate materials. The vibrating sand screening machine for steel preparation is widely used. The existing vibrating sand screening machine for steel preparation has certain disadvantages when in use. First, the amplitude of the vibrating sand screening machine is difficult to adjust, which affects the work efficiency. Secondly, the screen in the sand screening machine is easily damaged, and the damaged screen is difficult to disassemble. Finally, the material is easily accumulated under the sand screening machine, which requires people to clean it up again, which has a certain impact on the users.

[0003] The existing patent (publication number: CN208810532U) discloses a vibrating sand screening machine for steel preparation, including a vibrating screen body, a vibrating box is fixedly installed on the upper outer surface of the vibrating screen body, and a vibrating motor is riveted to the lower outer surface of the vibrating screen body, a fixing frame and a prompt sign are fixedly installed on the front outer surface of the vibrating box, a tensioning mechanism is fixedly installed on the lower outer surface of the fixing frame, and a fixing rod is movably installed inside the tensioning mechanism, a base is fixedly installed on the lower outer surface of the fixing rod, and a spring is provided on the upper outer surface of the base, and a nut is movably installed on the upper outer surface of the fixing frame.

[0004] The above-mentioned comparative document points out that the device is equipped with a tensioning mechanism, quick-release bolts and a conveyor belt, which can adjust the amplitude of the vibrating sand screen, quickly remove the damaged screen, and prevent materials from accumulating under the sand screen. However, the sieved sand has a certain fluidity. When using a conveyor belt to move the sand, the sieved sand may leak out from both sides of the transmission belt, causing the sand to accumulate on both sides of the conveyor belt. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a vibrating sand screening machine for steel preparation, which has the advantages of preventing material accumulation, etc., and solves the problem that the sand after screening has a certain fluidity. When the sand is moved by a conveyor belt, the sieved sand may leak out from both sides of the transmission belt, causing sand to accumulate on both sides of the conveyor belt.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a vibrating sand screening machine for steel preparation, comprising a base, a discharge hopper fixedly connected to the bottom end of the base, a fixed plate fixedly connected to one side of both ends of the discharge hopper, a rotating shaft rotatably connected between the two fixed plates, a plurality of shift plates fixedly connected to the outer wall of the rotating shaft, a motor fixedly connected to one side of one of the fixed plates, and the output end of the motor passes through the fixed plate and is fixedly connected to the rotating shaft through a coupling.

[0007] Through the above scheme, through the setting of the discharging hopper, the rotating shaft, the paddle plate and the motor, the sand falls into the discharging hopper after being screened. Since the bottom of the discharging hopper is inclined, the sand after being screened will move downward, and at the same time, the motor drives the rotating shaft to rotate, and the rotating shaft drives the paddle plate to rotate counterclockwise, so that the sand falling on the paddle plate is caused to fall through the rotation of the rotating shaft. When the sand accumulates, the sand will be pushed backward by the rotation of the paddle plate, so that the sand will not accumulate at the falling point, ensuring that the sand falls smoothly.

[0008] Furthermore, two fixed blocks are fixedly connected to one side of the upper end of the base, and one side of the two fixed blocks is fixedly connected to an electric push rod, the telescopic ends of the two electric push rods are fixedly connected to a mounting frame, three mounting blocks are fixedly connected on both sides of the inside of the mounting frame, and two sliding bars are fixedly connected to the bottom end of the mounting frame.

[0009] Through the above scheme, through the setting of the electric push rod, the electric push rod reciprocates and extends, driving the installation frame to reciprocate, which is used to imitate the action of manual screening, helps to improve the screening effect, and makes the material pass through the screen more evenly.

[0010] Furthermore, two slide grooves are fixedly provided on the upper end of the base.

[0011] Through the above solution, the slide groove is provided to provide a space for the installation frame to flow out and move.

[0012] Furthermore, the two slide bars are slidably arranged inside the two slide grooves respectively.

[0013] Through the above solution, the slide bar at the bottom end of the mounting block slides in the slide groove at the upper end of the base.

[0014] Furthermore, buffers are fixedly provided at both ends of the two slide grooves.

[0015] Through the above solution, the buffer is provided to reduce the impact force of the installation frame when it moves.

[0016] Furthermore, a screen is fixedly provided on the upper ends of the plurality of mounting blocks, and three fixing bolts are rotatably connected to both sides of the upper ends of the screen.

[0017] Through the above solution, the screen is a detachable structure and can be replaced separately when damaged.

[0018] Furthermore, the plurality of fixing bolts all penetrate the screen and are threadedly connected to the mounting block.

[0019] Through the above solution, the screen is fixed to the upper end of the mounting block by fixing bolts.

[0020] Furthermore, two support blocks are fixedly connected to both sides of the base, and the bottom ends of the four support blocks are fixedly connected to supporting legs.

[0021] Through the above scheme, the legs are used to support the device, leaving a space for dropping materials at the bottom of the discharge hopper.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The vibrating sand screening machine for steel preparation is provided with a discharging hopper, a rotating shaft, a paddle and a motor. After the sand is screened, it falls into the discharging hopper. Since the bottom of the discharging hopper is inclined, the sand after screening will move downward. At the same time, the motor drives the rotating shaft to rotate, and the rotating shaft drives the paddle to rotate counterclockwise, so that the sand falling on the paddle is caused to fall by the rotation of the rotating shaft. When the sand accumulates, the sand will be pushed backward by the rotation of the paddle, so that the sand will not accumulate at the falling place, ensuring the smooth falling of the sand. The electric push rod is provided to enable the screen to produce reciprocating motion, imitating the action of manual sand screening, which is helpful to improve the screening effect and make the material pass through the screen more evenly.

Two slide bars 13 are fixedly connected to the bottom end of the mounting frame 11. Through the setting of the electric push rods 10, the electric push rods 10 reciprocate and extend, driving the mounting frame 11 to reciprocate, which is used to imitate the action of manual screening, which helps to improve the screening effect and make the material pass through the screen 14 more evenly.

[0034] See also Figure 1 , Figure 2 and Figure 4Two slide grooves 7 are fixedly provided on the upper end of the base 1, and the slide groove 7 is a space provided for the installation frame 11 to flow out and move. Two slide bars 13 are slidably provided in the two slide grooves 7 respectively, and the slide bar 13 at the bottom end of the installation block 12 slides in the slide groove 7 at the upper end of the base 1. Buffers 8 are fixedly provided at both ends of the two slide grooves 7. The setting of the buffer 8 is used to reduce the impact force of the installation frame 11 when moving. A plurality of mounting blocks 12 are fixedly provided with screens 14 on the upper ends, and three fixing bolts 15 are rotatably connected on both sides of the upper ends of the screens 14. The screens 14 are detachable structures and can be replaced separately when damaged. A plurality of fixing bolts 15 all penetrate the screen 14 and are threadedly connected to the mounting block 12. The screen 14 is fixed to the upper end of the mounting block 12 by the fixing bolts 15. Two support blocks 16 are fixedly connected on both sides of the base 1, and the bottom ends of the four support blocks 16 are fixedly connected with legs 17. The legs 17 are used to support the device, leaving a blanking space at the bottom of the discharge hopper 2.

[0035] In this embodiment, the vibrating sand screening machine for steel preparation is configured with a discharge hopper 2, a rotating shaft 4, a paddle 5 and a motor 6. After the sand is screened, it falls into the discharge hopper 2. Since the bottom of the discharge hopper 2 is inclined, the sand after screening will move downward. At the same time, the motor 6 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the paddle 5 to rotate counterclockwise, so that the sand falling on the paddle 5 is caused to fall by the rotation of the rotating shaft 4. When the sand accumulates, the rotation of the paddle 5 will push the sand backward, so that the sand will not accumulate at the falling place, and the setting of the electric push rod 10 can make the screen 14 produce reciprocating motion, imitating the action of manual sand screening, so that the screening effect is better.

[0036] It should be noted that the rotation direction of the motor 6 is counterclockwise, which is used to move the fallen and accumulated sand so that it will not accumulate too high and block the discharge port of the discharge hopper 2.

[0037] The working principle of the above embodiment is:

[0038] First, the sand to be screened is put into the screen 14 inside the sand screening machine, and then the electric push rod 10 is started to reciprocate and extend, driving the installation frame 11 and the screen 14 thereon to reciprocate. This movement imitates the action of manual sand screening, which helps to improve the screening effect and make the material pass through the screen 14 more evenly. Larger particles or materials that do not meet the requirements are intercepted by the screen 14, while smaller particles that meet the requirements continue to fall through the screen 14 and fall into the inside of the discharge hopper 2. The screened sand is smoothly discharged through the inclined design of the discharge hopper 2. At the same time, the motor 6 is started to drive the rotating shaft 4 and the paddle 5 fixed on the rotating shaft 4 to rotate. The paddle 5 rotates counterclockwise, so that the sand falling on it falls under the action of gravity. If the sand accumulates at the drop point of the discharge hopper 2, the paddle 5 will paddle it backwards to prevent blockage and ensure that the sand falls smoothly.
