Description

technical field

[0001] The invention relates to the technical field of downhole dust prevention, in particular to a rolling shutter type dust catcher. Background technique

[0002] The function of the dust catcher is to reduce the dust generated in the coal cutting process and prevent the dust from exceeding the standard. The dust catcher net in the tail lane of the fully mechanized mining face is often used poorly. In the past, it was made of door frame type, push-pull type, etc., and it was made of angle iron and square steel. Difficult to move and flawed in design. There are many problems in actual use. When transporting materials or getting in and out of the car, there is not much space, and the bearings on the runway are easily rusted due to moisture in the tail alley, and the activities are not flexible. Contents of the invention

[0003] The object of the present invention is to provide a roller shutter type dust catcher device in order to solve the above-mentione...
