TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction engineering equipment, and specifically relates to a vibrating screen unblocking device. BACKGROUND

[0002] The parent material used in the production of the tunnel slag sand and gravel yard is tunnel slag, and due to the complex geology along the CZ railway and the variable lithology of the mountain, the lithology of the tunnel slag varies greatly. At the same time, the plateau of Tibet is high in altitude, and the weather and climate change greatly, and there are more rainy and snowy weather, so the moisture content of the tunnel slag parent material is generally high.

[0003] During the production process of the core processing yard, due to the wet material (the tunnel slag parent material has a high moisture content), the broken parent material (especially the aggregate with a particle size of ≤10mm) is easy to stick and not easy to pass through the screen hole when passing through the vibrating screen, which may cause the screen hole to be blocked. Although the existing technology has a replaceable anti-blocking vibrating screen filter screen, such filter screen is high in cost, and if the anti-blocking filter screen is used in large-area engineering site, the ordinary vibrating screen filter screen will be eliminated and scrapped, and the engineering cost will be greatly increased.

[0025] Please refer to Figures 1-4 .

[0026] The utility model provides a kind of technical scheme of vibration screen clearing device: a kind of vibration screen clearing device, including the bracket 101 being arranged on vibration screen 1 and the vibration screen 102 being arranged in bracket 101, vibration screen 102 is fixed on bracket 101 by bolt, and generally vibration screen 102 is divided into two layers, the screen mesh interval density of two layers vibration screen 102 is different, the density is greater in upper, the density is smaller in lower, this is prior art, without too much repetition here, further include: vibration adjustment assembly 2 is arranged in the side surface of bracket 101, to adjust the vibration amplitude of vibration screen 102;Elastic component 3 is arranged in the side surface of vibration screen 102, to cooperate vibration adjustment assembly 2 to drive the further vibration of vibration screen 102.

[0027] By setting the vibration adjusting assembly 2 and the elastic assembly 3, when the screen mesh 102 on the vibrating screen 1 is blocked, the vibration frequency of the vibrating screen 1 is first adjusted by the vibration adjusting assembly 2, and the eccentric weight is reduced to increase the vibration frequency. Through high-frequency vibration, the stones stuck in the screen mesh 102 are shaken off. At the same time, when the elastic assembly 3 set at the lower end of the screen mesh 102 is in mutual resistance, the rebound force generated by the resistance will further strengthen the vibration of the screen mesh 102, so that the stones stuck in the screen mesh 102 are shaken off without excessive cost.

[0028] In an embodiment, the vibration adjusting assembly 2 includes an eccentric shaft 201 and an eccentric block 202 fixedly arranged at one end of the eccentric shaft 201. The other end of the eccentric shaft 201 is provided with a motor, which can drive the eccentric shaft 201 and the eccentric block 202 to rotate. When the eccentric shaft 201 rotates, the eccentric block 202 fixedly arranged thereon rotates to generate vibration, which makes the materials on the screen mesh 102 move in a throwing motion, thereby achieving the purpose of screening and separation. This is prior art and will not be described in detail here. One end of the eccentric shaft 201 is slidably provided with a limiting clamp 204. One side surface of the eccentric block 202 is provided with a plurality of placement grooves 2021. A counterweight 203 is arranged in each placement groove 2021. The placement grooves 2021 are arranged to install the counterweight 203. The counterweight 203 is arranged to facilitate changing the weight of the eccentric block 202. Reducing the weight of the eccentric block 202 will reduce the inertial moment of the system, which will cause the vibration frequency to increase. Because smaller moments can produce angular acceleration faster, this is a known technology. One side surface of the counterweight 203 is fixedly provided with a connecting pile 2031. One side surface of the limiting clamp 204 is provided with a groove matched with the connecting pile 2031. This arrangement is to enable the limiting clamp 204 to limit the position of the counterweight 203 through the connecting pile 2031, so that the counterweight 203 does not fall out of the placement groove 2021 when the eccentric block 202 rotates. The limiting clamp 204 is slidably connected to the eccentric shaft 201 through a connecting shaft 2041. One end of the connecting shaft 2041 is provided with a special-shaped pile 2042. The other end of the special-shaped pile 2042 is slidably arranged at one end of the eccentric shaft 201. This arrangement is to enable the limiting clamp 204 to slide on the eccentric shaft 201, but when the eccentric shaft 201 rotates, the limiting clamp 204 can also rotate synchronously. In addition, the special-shaped pile 2042 and the eccentric shaft 201 have a certain damping, so the limiting clamp 204 cannot easily slide on the eccentric shaft 201.

[0029] In this way, when more stones are clamped on the vibrating screen 102 on the vibrating screen 1, the vibrating screen 102 cannot normally screen, the limiting clamp 204 is moved to one end, the limiting clamp 204 is moved, the special-shaped pile 2042 is pulled out from the eccentric shaft 201 by a distance, at this time, the limiting clamp 204 no longer limits the counterweight block 203 on one side of the eccentric block 202, a part of the counterweight block 203 is taken out through the connecting pile 2031, the limiting clamp 204 is pushed into the initial position, at this time, the vibrating screen 1 is started again, the vibration frequency of the vibrating screen 1 is increased with the decrease of the mass of the eccentric block 202, and the vibration amplitude of the vibrating screen 102 is increased.

[0030] In an embodiment, a plurality of elastic balls 301 are fixedly arranged on one side of the vibrating screen 102 in parallel, the elastic balls 301 are uniformly arranged at positions where the stones flow through the screen surface more concentratedly, the diameter of the elastic ball 301 is greater than the gap diameter of the vibrating screen 102, the elastic ball 301 cannot be clamped in the vibrating screen 102, and a plurality of abutting beams 302 are fixedly arranged between the supports 101, and the elastic balls 301 are arranged above the abutting beams 302.

[0031] In this way, when the vibration amplitude of the vibrating screen 102 is increased, the elastic balls 301 arranged at the lower end of the vibrating screen 102 will abut against the abutting beams 302 arranged on the support 101 in each vibration process, the elastic balls 301 are abutted, and the elastic force of the elastic balls 301 will act on the vibrating screen 102 at the same time, so that the vibrating screen 102 locally generates a rebound effect, so that the stones clamped on the vibrating screen 102 or attached to the vibrating screen 102 near the position of the elastic balls 301 fall off.

[0032] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
