Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in fig. 1-4, a dust collection cover comprises a cover body 1 and a dust collection pipeline 2 which is communicated with the top of the cover body; the front wall and the right side wall of the cover body 1 are provided with two doors 3, the doors 3 are hinged on the front wall and the opening surface of one side wall of the cover body 1 through hinges 4, the doors 3 are provided with handles 5, through holes and insertion rods 6 are arranged in the handles 5, and the insertion rods 6 lock the doors 3 through the through holes of the handles 5; the other side wall is provided with an opening 7 penetrating through the top wall of the cover body 1, a longitudinal sliding chute 8 is arranged in the side wall of the cover body 1 corresponding to the opening 7, and the longitudinal sliding chutes 8 are all connected with a baffle 9 in a sliding manner; the baffle 9 comprises a vertical plate 10 and a horizontal plate 11, and the top surface of the vertical plate 9 is connected with the bottom surface of the horizontal plate 11; the vertical plate 10 is connected with the longitudinal sliding chute 8 in a sliding way, and the height of the vertical plate is the same as that of the longitudinal sliding chute 8; the horizontal plate 11 is located above the opening 7 and has a length greater than that of the opening 7.
