Description

Blind plate anti-drop device before shale shaker sieve Technical Field The utility model belongs to the technical field of coal devices, and particularly relates to a vibrating screen front blind plate anti-falling device. Background Vibrating screens are currently the most widely used screening machine in many industries. In the production links of screening, dewatering, desliming, medium removal and the like of a coal preparation plant, a vibrating screen basically works. In the coal industry, the vibrating screen is the most widely used classifying, dehydrating, medium removing and desliming equipment, and is also a key screening equipment, and the quality of classifying and dehydrating effects and the screening quantity directly influence the quality and efficiency of coal dressing. In terms of coal processing, screening and sorting technologies are equally important. Therefore, the stability of the vibrating screen in actual work is a necessary condition for ensuring screening and washing, and has important practical significance in the coal industry in China. The vibrating screen mainly comprises a supporting device, a screen box, a motor and a vibration exciter, wherein the motor drives the vibration exciter to rotate through a connecting piece, the screen box vibrates due to centrifugal inertia force, the vibration process is a material washing and selecting processing process, and the continuous operation of the vibrating screen can cause no small potential safety hazard to the vibrating screen. In the operation process of the vibrating screen, because the components age, deform and vibrate, a large gap exists between a rail seat and the blind plate, and the situation that the blind plate falls off can not be absolutely avoided by adding a pad skin along with continuous vibration operation, so that accidents such as incapability of operating a screen machine, blockage of a hopper under the screen and the like can be caused, and the operation of the whole coal washing system is influenced. Disclosure of utility model Aiming at the problem that the front blind plate of the existing vibrating screen falls off along with continuous vibrating operation, the utility model provides an anti-falling device for the front blind plate of the vibrating screen. In order to solve the problems, the utility model adopts the following technical scheme: The utility model provides a blind plate anti falling device before shale shaker sieve, includes the rail seat, the both sides of rail seat are equipped with the blind plate, the top of blind plate is equipped with the clamp plate, be equipped with connecting plate one between clamp plate and the blind plate, the one end of connecting plate one is connected with connecting plate two perpendicularly, connecting plate two is adjacent with the side of rail seat, the surface of clamp plate is equipped with fixed orifices one, the surface of connecting plate one is equipped with the fixed orifices two that correspond with fixed orifices one, wears to be equipped with fastening bolt in fixed orifices one and the fixed orifices two, and clamp plate, connecting plate one, rail seat pass through fastening bolt to be connected as an organic wholely. Further, the first connecting plate is the same as the pressing plate in length. Further, the vertical central axis of the second connecting plate and the vertical central axis of the rail seat are positioned on the same straight line. Further, the bottom of the second connecting plate is flush with the bottom of the rail seat. Further, the central axes of the pressing plate, the first connecting plate and the rail seat are positioned on the same straight line.
