Description

Technical Field

[0001] This utility model relates to the field of material screening technology, specifically a vibrating cleaning screen device. Background Technology

[0002] Screening devices are used in the food and feed manufacturing and processing industries. Common material screening devices often use a vibrating motor to provide excitation force to the screening hopper, thereby screening the material. During the screening process, some irregularly shaped and larger material particles may cause blockages during the discharge process, making it difficult to clean the discharge chute. In addition, dust is generated during the screening process, which can affect nearby workers if not handled in time. Screening materials often have an upper and lower screen plate structure, and the material is discharged in the same direction after screening, causing the collection bags to collide and limit each other, making it difficult to collect material particles of different sizes after screening. To address this issue, this solution provides a vibrating cleaning screen device. Utility Model Content

[0010] Beneficial effects

[0011] This utility model provides a vibrating cleaning screen device, which has the following beneficial effects:

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a vibrating cleaning screen device, including a mounting frame 1, a box 2 and a feeding hopper 3. The box 2, which is inclined downward, is fixedly installed on the mounting frame 1. The feeding hopper 3 is connected to the top of the box 2. A screening box 4 is provided inside the box 2. A first discharge trough 5 is provided at the bottom end of the inclined surface of the box 2. A second discharge trough 6 is provided at the top end of the first discharge trough 5. A blower 7 is installed on the top surface of the box 2. The inside of the screening box 4 is divided into two layers by a fixed inclined screen 8. The first discharge trough 5 is connected to the lower side of the screening box 4 along the length of the box 2. The second discharge trough 6 is located on the inclined downward side of the inclined screen 8.

[0020] The screen box 4 has folded edges 9 on both sides and a vibrating table mounting base 10 at the bottom. Vertical spring sleeves 11 are fixedly installed on both the left and right sides of the vibrating table mounting base 10. The top of the spring sleeves 11 is connected and fixed to the folded edges 9 through spring parts 12. A drive motor 13 is fixedly installed on the outside of the vibrating table mounting base 10. A rotating shaft 14 is installed at one end of the drive motor 13 and is horizontally installed on the vibrating table mounting base 10. A crank rocker mechanism is provided at the center of the rotating shaft 14.

[0021] The crank-rocker mechanism includes a crank 15 and a moving rod 16, wherein the rotating shaft 14 and the crank 15 are fixedly connected, the end of the crank 15 is connected to the moving rod 16, and the top end of the moving rod 16 is connected to the vibrating table 17 through a rotating pin. The vibrating table 17 and the bottom surface of the screen box 4 are fixed together.

[0022] An electric push rod 18 is provided on the outside of the second discharge chute 6. The end of the electric push rod 18 is connected to a brush plate 19, and the brush plate 19 is located inside the second discharge chute 6. When the irregular large particles of material slide down the inclined screen 8 to the second discharge chute 6, blockage may occur. The electric push rod 18 can push the brush plate 19 to slide in the second discharge chute 6 to push out the blocked material.

[0023] The second discharge trough 6 and the box 2 are fixedly connected to form an L-shaped connection structure, that is, large irregular particles of material will slide down the inclined screen 8 to the second discharge trough 6. The discharge port of the second discharge trough 6 and the discharge port of the first discharge trough 5 are not in the same direction, which makes it easier to collect the material after screening.

[0024] The drive motor 13 drives the rotating shaft 14 to rotate, and the rotating shaft 14 drives the crank 15 to move eccentrically, so that the crank 15 drives the moving rod 16 to move. The top of the moving rod 16 is rotatably connected to the vibrating table 17 through the rotating shaft. The moving rod 16 drives the vibrating table 17 to move up and down, so that the screen box 4 vibrates up and down as a whole.

[0025] Working principle:

[0026] The top of the screening box 4 inside the box 2 is located directly below the feed hopper 3. The material is fed from the feed hopper 3 and falls into the screening box 4 inside the box 2. It is screened by the inclined screen 8 inside the screening box 4. The material larger than the mesh size will slide down the inclined screen 8 to the second discharge chute 6, and the material smaller than the mesh size will slide down the screening box 4 to the first discharge chute 5. The bottom of the screening box 4 is supported by the vibrating table 17. The vibrating table 17 is fixed to the bottom of the box 2 inside by the vibrating table mounting base 10. Since the box 2 is fixed at an incline on the mounting frame 1, the screening box 4 itself is also inclined inside the box 2.

[0027] When the material falls into the screen box 4, the drive motor 13 works, driving the rotating shaft 14 to rotate. The rotating shaft 14 and the crank 15 are fixedly connected. The rotating shaft 14 drives the crank 15 to perform eccentric motion. During the eccentric motion of the crank 15, the top part of the moving rod 16 and the vibrating table 17 are connected to the rotating shaft. Thus, under the rotation of the rotating shaft 14, the vibrating table 17 is driven to vibrate up and down through the cooperation of the crank rocker mechanism. The vibrating table 17 drives the screen box 4 to vibrate up and down as a whole. The left and right sides of the screen box 4 are connected by the spring 12 and the folded edge 9 to maintain the stability of the screen box 4 during the overall vibration process.

[0028] The material is screened more quickly at the inclined screen 8 of the vibrating screen box 4. The screened material is discharged from the first discharge chute 5 and the second discharge chute 6 respectively. Large particles and irregularly shaped materials in the second discharge chute 6 can be pushed out by the operation of the electric push rod 18, which drives the brush plate 19 to extend and retract in the second discharge chute 6, thus avoiding the clogging phenomenon of large particles and irregularly shaped materials during the screening process.

[0029] Throughout the screening process, the exhaust fan 7 can be powered by an external power source. A filter screen can be installed at the air outlet of the exhaust fan 7 to absorb some of the dust generated during the material falling and rolling inside the screen box 4.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
