Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a spring-arm vibrating screen. Background Art

[0002] The spring-arm vibrating screen is a screening equipment, which is widely used in various industries such as mining, coal, electricity, metallurgy, building materials, refractory, etc. for grading large materials and medium and small granular materials. It can screen a variety of particles. When using the spring-arm vibrating screen for screening operations, it is generally provided with a feed port and multiple discharge ports. There are many types of spring-arm vibrating screens on the market, which can be divided into multiple categories according to the different screening raw materials.

[0003] The utility model patent with authorization announcement number CN218591087U discloses an easily adjustable spring-arm vibrating screen, which relates to the technical field of vibrating screens, including a screen box and a support frame, two vibration motors are fixedly arranged on the top of the screen box, a screen plate is fixedly arranged inside the screen box, a vibration structure for vibrating the screen plate is arranged at the bottom of the screen plate, a first fixed seat is fixedly arranged at one end of the bottom of the screen box, a first rotating seat rotatably connected to the first fixed seat is fixedly arranged on one side of the top of the support frame, a first hinged seat is fixedly arranged at one end of the bottom of the screen box, and a second hinged seat is fixedly arranged on the other side of the top of the support frame. The beneficial effects of the utility model are as follows: the angle of the screen box can be adjusted by an articulated adjusting cylinder so that it rotates around the first rotating seat as the axis, which is convenient for adjusting the angle of the screen box; the vibration structure is arranged to facilitate the vibration of the surface of the screen plate to prevent the screen holes of the screen plate from being blocked, thereby improving the screening efficiency.

[0004] Although this technical solution has the advantage of being easy to adjust the angle of the screen box and improving the screening efficiency, in actual use, since it uses the telescopic shaft of the cylinder to extend and shorten to achieve the angle adjustment operation, it lacks a component that can stably support the bottom of the vibrating screen after adjustment. Since the vibrating screen will vibrate when working, the frequent vibration force acting on the telescopic shaft of the cylinder will affect the telescopic shaft of the cylinder and affect the subsequent use of the cylinder. In view of this, we propose a spring-arm vibrating screen. Utility Model Content
