Description

Technical Field

[0001] The utility model relates to the technical field of preventing blocking, in particular to a linear vibrating screen with an anti-blocking function. Background Art

[0002] The linear vibrating screen uses the vibration motor as the vibration source to throw the material on the screen and move forward linearly. The material enters the feed port of the screening machine evenly from the feeder, and passes through the multi-layer screen to produce several specifications of oversize and undersize, which are discharged from their respective outlets. It has low energy consumption, high output, simple structure, easy maintenance, fully enclosed structure, no dust spillage, automatic discharge, and is more suitable for assembly line operation.

[0003] Compared with the existing technology: the existing linear vibrating screen cannot control the amount of material entering to prevent blocking, so when the amount of material entering is too large, the material accumulation on the screen will increase rapidly, causing the screen to be blocked. This will affect the normal screening function of the screen, making it impossible for the material to be effectively separated through the screen, and the screen blockage will directly lead to a decrease in screening efficiency, because the blocked screen will hinder the normal flow of the material, increasing the residence time of the material on the screen surface and failing to be discharged in time, which will lead to a decrease in screening effect and affect product quality.

[0004] Therefore, a linear vibrating screen with anti-blocking function is proposed. Utility Model Content

At this time, the damper 212 and the connecting spring 213 move, and the impact of the movement of the body 1 on the supporting legs 214 is reduced.

[0030] Example 2

[0031] On the basis of Example 1, a preferred embodiment of a linear vibrating screen with anti-blocking function provided by the utility model is as follows Figure 1-4 As shown: the driving part 31 includes: a fixed tube 311, which is arranged on the top of the body 1; the bottom of the fixed tube 311 is fixedly connected to the top of the body 1, the fixed tube 311 is connected to the feed port, the inner wall of the fixed tube 311 is rotatably connected to a rotating rod 312, one side of the rotating rod 312 is fixedly connected to a motor 313, the outer wall of the rotating rod 312 is fixedly connected to a fan blade 315, and the outer wall of the motor 313 is fixedly connected to a fixed platform 314.

[0033] Furthermore, in this embodiment, by starting the motor 313, the operation of the motor 313 drives the rotating rod 312 to rotate, and the rotation of the rotating rod 312 drives the fan blades 315 to rotate.

[0037] Furthermore, in this embodiment, when the fan blade 315 rotates and contacts the driving rod 325, the driving rod 325 is squeezed to move the driving rod 325 upward. The upward movement of the driving rod 325 drives the baffle 324 to move upward. At this time, a gap is generated between the baffle 324 and the storage hopper 321, and the material falls into the fixed tube 311 through the gap, and then falls into the machine body 1 through the fan blade 315.

At this time, the damper 212 and the connecting spring 213 move, and reduce the impact of the movement of the body 1 on the supporting legs 214. At the same time, the movement of the body 1 drives the screening plate 1 215 and the screening plate 2 216 to move. The movement of the screening plate 1 215 and the screening plate 2 216 drives the material to be screened, and then discharged through the discharger 217, thereby achieving the screening of the material.
