[0002] Tea processing is a complex process of converting fresh tea leaves into drinkable products. It involves multiple steps, and the specific process varies depending on the type of tea to be produced (such as green tea, black tea, oolong tea, white tea, yellow tea, dark tea, etc.). During tea processing, tea screening equipment is required to screen the tea leaves. During the screening process, in order to avoid dust, a tea screening dust removal device is required to absorb the dust caused by screening.

[0003] The existing dust removal device for tea screening uses a bracket to support the dust suction head, so that the dust suction head is located on the upper side of the tea screening device, and the air pump drives the dust suction head to suck air, so as to absorb the dust generated during the screening process, and the dust generated during the screening process is sucked into the dust suction box, thereby achieving dust removal during the tea screening process. However, in actual use, due to the different shapes and sizes of different tea screening devices, the positions and heights of the tea leaves are also different, which results in the bracket being unable to adapt well to various screening devices to drive the dust suction head to remove dust therefrom. When removing dust from different tea screening devices, it is necessary to replace brackets of different models and specifications, and the versatility is poor. Utility Model Content
