[0002] The caterpillar mobile screening station is composed of a hopper, a feeding conveyor, a feeding conveyor head support rod, a vibrating screen, a top side finished product conveyor, a middle side finished product conveyor, a bottom side finished product conveyor, a screen under finished product conveyor, a caterpillar frame, a screen frame and a screen frame support rod.

[0003] When the caterpillar mobile screening station is working, the proper screening angle needs to be determined according to the nature of the screened material and the size of the screen used. In order to ensure that the screening rate meets the requirements of aggregate use, the material that is not easy to separate (such as material with high mud content and water content) needs more time to be screened on the screening machine compared with the material that is easy to separate (such as dry sand or loose gravel).

[0004] In addition, the type and size of the screen also affect the selection of the screening angle. Generally, a square mesh screen requires a smaller screening angle than a slot-shaped screen, and a harp-shaped metal screen requires a very large angle. Selecting the correct screening angle can greatly improve the yield.

[0005] However, the screening angle of the existing mobile screening station on the market is not adjustable, which greatly limits the main performance of the mobile screening station, such as processing capacity. UTILITY MODEL CONTENT
