Description

Technical Field

[0001] The utility model relates to the field of screening equipment, in particular to a linear vibrating screen. Background Art

[0002] At present, linear vibrating screens are prone to middle depression after long-term screening because the raw materials are concentrated in the middle of the screen when they are fed, which greatly reduces the service life of the screen. There is a lack of a vibrating screen that can feed raw materials evenly and avoid depression in the middle. Utility Model Content

[0003] The purpose of this utility model is to provide a linear vibrating screen to address the above-mentioned deficiencies.

[0004] The utility model includes a vibration frame and a screen.

[0005] A screen fixing plate is provided on the inner walls of both sides of the vibration frame, and a pad is provided at one end of the screen fixing plate. The screen is placed on a pair of screen fixing plates and fixed to the screen fixing plates by U-shaped locking nails. The U-shaped locking nails press down both sides of the screen, and the middle part of the screen arches upward to form an arc under the support of the pad.

[0006] A plurality of groups of nail holes are arranged in sequence on the screen fixing plate, and U-shaped locking nails are inserted into the nail holes on the screen and the screen fixing plate and are locked and fixed by a pair of nuts.

[0007] A group of inclined material blocking plates are arranged in sequence on the inner wall of the vibration frame, and the inclined material blocking plates are located between a pair of adjacent U-shaped locking pins.

[0008] One end of the pad is an arc-shaped surface.

[0009] A plurality of reinforcing ribs are arranged between the bottom surface of the screen fixing plate and the inner wall of the vibration frame.

[0010] The inlet end of the vibrating frame is provided with an inclined feed plate.

[0011] A vibration motor is arranged at the bottom of the vibration frame.

[0012] A screen supporting cross bar is arranged between a pair of screen fixing plates.

[0013] The utility model has the advantages that the two sides of the screen are fixed by the U-shaped locking nails, and under the pressure of the U-shaped locking nails, the middle of the screen is slightly arched upward, and the raw materials are evenly spread when feeding, avoiding the raw materials from being concentrated in the middle of the screen.

[0023] As shown in the accompanying drawings, the utility model includes a vibration frame 1 and a screen 2.

[0024] A screen fixing plate 3 is respectively provided on the inner walls of both sides of the vibration frame 1, and a pad 4 is provided at one end of the screen fixing plate 3. The screen 2 is placed on a pair of screen fixing plates 3 and fixed to the screen fixing plates 3 by U-shaped locking nails 5. The U-shaped locking nails 5 press down both sides of the screen 2, and under the support of the pad 4, the middle part of the screen 2 arches upward to form an arc.

[0025] A plurality of groups of nail holes are arranged in sequence on the screen fixing plate 3, and the U-shaped locking nails 5 are inserted into the nail holes on the screen 2 and the screen fixing plate 3 and are locked and fixed by a pair of nuts.

[0026] A group of inclined material blocking plates 6 are arranged in sequence on the inner wall of the vibration frame 1 , and the inclined material blocking plates 6 are located between a pair of adjacent U-shaped locking pins 5 .

[0027] One end of the pad 4 is an arcuate surface 7, which makes the two sides of the screen 2 rotate more smoothly around the pad 4 when clamped and fixed.

[0028] A plurality of groups of reinforcing ribs 8 are provided between the bottom surface of the screen fixing plate 3 and the inner wall of the vibration frame 1. The reinforcing ribs 8 make the screen fixing plate 3 stronger.

[0029] An inclined feed plate 9 is provided at the inlet end of the vibration frame 1 .

[0030] A vibration motor is provided at the bottom of the vibration frame 1 .

[0031] A screen supporting cross bar is provided between a pair of screen fixing plates 3 .

[0032] Example 1: The screened raw materials fall onto the screen 2 through the inclined feed plate 9. After being screened by the screen 2, the large-particle raw materials are output through the discharge port of the screen 2, and the small-particle raw materials fall into the receiving hopper below the vibrating screen through the pores of the screen 2. During installation, the screen 2 is first placed on a pair of screen fixing plates 3. A plurality of U-shaped locking nails 5 are sequentially inserted into the nail holes, and then tightened with nuts. The sides of the screen 2 are clamped and fixed to the screen fixing plates 3 through the U-shaped locking nails 5. When clamping, the pads 4 protrude upward, pressing down the two sides of the screen 2, and slightly arching the middle to form an arc-shaped screen. When entering the screen 2, the raw materials can be evenly distributed on the screen 2 and will not all be concentrated in the middle, thus preventing the middle of the screen 2 from sinking downward. The raw materials on both sides are guided to flow to the middle of the screen by the inclined retaining plate 6 to avoid friction between the raw materials and the U-shaped locking nails 5.
