Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, and more specifically to a vibrating screen that is not easily blocked. Background Art

[0002] Vibrating screen is a device used to separate particles of different sizes. It is widely used in mining, coal, electricity, building materials, chemical industry and other industries. Its working principle is to drive the screen to produce high-frequency vibration through the motor. The material on the screen surface is affected by the vibration force. The material smaller than the screen hole is separated through the screen hole, and the material larger than the screen hole remains on the screen surface and continues to move forward until it is discharged.

[0003] The circular vibrating screen is a type of vibrating screen, which is mainly composed of a screen box, a screen, a vibrator, a shock-absorbing spring and a driving device. According to different usage requirements, the vibrating screen can be designed as a single layer or a multi-layer to achieve multi-level screening of materials. For example, the Chinese patent with application number 202223319420.5 discloses a circular vibrating screen, which includes a vibrating seat and a screen cylinder, wherein the vibrating seat is arranged on the ground; the screen cylinder is arranged on the side of the vibrating seat away from the ground; it also includes a first screen and a second screen, wherein the first screen is arranged in the screen cylinder; the second screen is concentrically arranged on one side end face of the first screen, and the second screen can rotate along the circumference of the first screen; and a number of screen holes are provided on the first screen and the second screen. In the daily production and use of this circular vibrating screen, although the screen inside is in a vibrating state, the material will still be blocked in the screen hole.

The vibration of the vibrating screen body 101 drives the knocking ball 110 to move up and down, thereby knocking a knocking plate 118, and the knocking plate 118 drives the top knocking bar 119 to hit the filter screen 115, so that the material blocked on the filter screen is ejected, and the inner ring surface of the support frame 102 is provided with a cavity 104, and a movable The movable plate 105 is connected to a ring plate 106 on the inner ring surface of the movable plate 105, and a support rod 107 is connected to the inner ring surface of the ring plate 106. The movable plate 105 moves up and down in the cavity 104, and drives the support rod 107 on the inner ring surface to move up and down. The top of the outer wall of the support rod 107 is connected to an inclined block 108, and the inclined block 108 is connected to a knocking spring 109. One end of the knocking spring 109 is fixed to the inclined block 108, so that the knocking ball 110 at the other end can be inclined to contact the filter 115, and the top of the knocking spring 109 is connected to the knocking ball 110;

[0026] refer to Figures 2 to 4, an annular plate 111 is provided at the bottom of the movable plate 105, and a compression spring 112 is connected between the movable plate 105 and the annular plate 111, and the compression spring 112 pushes the movable plate 105 to move upward, so that the arc panel 113 at the top can come into contact with the tooth panel 114, the top of the movable plate 105 is connected with the arc panel 113, and the top of the cavity 104 is connected with the tooth panel 114, the tooth surface of the tooth panel 114 is arranged toward the movable plate 105, and the tooth tip of the tooth panel 114 is in the opposite direction to the arc panel 113, and the top of the arc panel 113 is in close contact with the tooth panel 114, and when the movable plate 105 shakes, the arc panel 113 at the top is in contact with the tooth panel 114, so that it can move to the opposite side of the arc panel 113;

[0027] refer to Figure 5 The screen 103 includes a filter 115, an outer ring 116, an inner ring 117 and a knocking plate 118. A connecting strip is connected between the outer ring 116, the inner ring 117 and the knocking plate 118. The filter 115 is connected to the inner ring 117 and the outer ring 116. The knocking plate 118 is located at the top of the knocking ball 110. The position of the knocking plate 118 corresponds to the position of the knocking ball 110. The knocking plate 118 is annular. When the moving plate 105 rotates due to vibration, it will drive the knocking ball 110 to rotate and knock. The top circumferential array of the knocking plate 118 has knocking The knocking strip 119 has one end facing the inner ring 117, and the top of the knocking strip 119 is provided with an arc surface. The knocking strips 119 are arranged in a circular array on the knocking plate 118. When the knocking ball 110 knocks the knocking plate 118, the knocking plate 118 will drive the top knocking strip 119 to come into contact with the filter 115, thereby squeezing out the objects blocking the sieve holes above, and the filter 115 will vibrate greatly, and the vibration will spread around, thereby shaking off the solid objects in the nearby sieve holes. There is a distance between the knocking strip 119 and the filter 115.

[0028] Specifically, refer to Figure 6The knocking ball 110 is hollow inside. When the knocking ball 110 shakes up and down, it will drive the shaking ball 121 inside to shake up and down, thereby increasing the shaking of the knocking ball 110. It should be noted that when the vibrating screen body 101 is screening, it will not only shake up and down, but also shake left and right, so that the knocking ball 110 will also shake left and right, but the left and right shaking will not affect the knocking effect of the knocking ball 110. The inside of the knocking ball 110 is connected with symmetrically arranged shaking springs 120, and the shaking ball 121 is connected between the symmetrical shaking springs 120. The knocking spring 109 and the shaking spring 120 are vertically arranged, and the shaking spring 120 is horizontally arranged. The shaking springs 120 on both sides can limit the horizontal shaking of the shaking ball 121 and increase the force of the up and down shaking. When the knocking ball 110 shakes up and down, the shaking spring 120 can increase the strength of the up and down shaking of the shaking ball 121.

[0029] Specifically, refer to Figure 2 and Figure 3 The upper and lower ends of the ring plate 106 are connected with inclined rings 122. When material falls from the top of the ring plate 106, it will slide from the inclined surface to the screen structure at the bottom and will not fall on the top of the ring plate 106. The inclined ring 122 at the bottom can prevent material dust from entering the cavity 104.

[0030] In this embodiment, the screen 103 is located between the two support frames 102. When material falls on the screen 103, the vibrating screen 103 will screen the material. When the vibrating screen body 101 vibrates, the movable plate 105 will slide up and down in the cavity 104. Through the contact between the top arc panel 113 and the tooth panel 114, rotation can be generated. At this time, the knocking spring 109 drives the top knocking ball 110 to move up and down. At this time, the knocking ball 110 can rotate to knock the knocking plate 118. The knocking plate 118 drives the top knocking bar 119 to knock the filter 115, thereby ejecting the material blocked on the screen hole. When the filter 115 vibrates, it will drive the surrounding area to vibrate, thereby improving the screening capacity.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
