In another embodiment, as shown in fig. 5 to 6, the ash removal assembly includes a second filter screen 700 and a third filter screen 600, the third filter screen 600 is fixedly connected with the scraper, the third filter screen 600 is perpendicular to the first filter screen 120, the third filter screen 600 is rotatably connected with the second filter screen 700 through a torsion spring, the two second filter screens 700 are arranged in an inclined manner, and the inclined direction is a direction in which the connecting ends of the second filter screen 700 and the third filter screen 600 point to the movable ends; the dust discharge holes 205 are formed in the space defined by the two second screens 700, the two third screens 600 and the first screen 120. So that when the two scrapers move relative to each other, the third filter screen 600 is moved to make the second filter screen 700 rotate closer. Finally, the two third sieves 600 are contacted, and a power device is arranged. An exhaust fan, etc. may exhaust dust from the dust exhaust hole 205.
The working process comprises the following steps: the ventilation device of this application installs in ventilation pipe 100, and normal conditions, the ventilation device of this application can normal use as a environmental protection professional equipment that the reaction is good in the pit work, improves workman operational environment.
Setting the direction of the wind flow entering the ventilation duct 100 as the first direction, when more dust is accumulated on the first filter screen 120, the first filter screen 120 cannot ventilate well, and thus the acting force of the ventilation in the duct applied to the first filter screen 120 gradually increases. Vertical grooves 202 are formed in the bottom plate 200 and the top plate 300, the first filter screen 120 and the connecting piece of the first filter screen 120 move towards the first direction under the action of wind, the first spring 123 fixedly connected with the first filter screen 120 is gradually compressed, the first spring 123 is connected with the first filter screen 120 and the bottom plate 200, in the process, the wind shielding assembly 400 slides towards the first direction under the action of wind, the first telescopic rod 401 is hinged to the fixing column 201 fixed on the bottom plate 200, therefore, when the movable assembly moves, the first telescopic rod 401 is pulled, the first telescopic rod 401 and the first sleeve 403 are enabled to move relatively, the ball block 402 is arranged at one end of the telescopic rod, the ball block 402 is sleeved with the first sleeve 403, the ball block 402 can be pulled out of the first sleeve 403 when the tensile force is large enough, and at the moment, the first telescopic rod 401 cannot be separated from the first sleeve 403.
The third baffle 206 is disposed at the end of the vertical slot 202, and the two third baffles 206 are symmetrically disposed on the bottom plate 200 and the top plate 300, so that the first screen 120 is stopped by the third baffles 206 and cannot move backward. When the first filter screen 120 cannot move continuously, the force of the ventilation in the duct will continue to act on the wind shielding assembly 400, so that the wind shielding assembly 400 can move independently in the first direction to drive the two obliquely arranged connecting frames 500 hinged to the two first hinge frames 409 to move synchronously.
The other ends of the two connecting frames 500 are hinged to third hinge columns 801 arranged on the scraper, sliding columns 803 are arranged at the lower ends of the third hinge columns 801, the third hinge columns 801 are fixed to the two third filter screens 600, and the other ends of the two third filter screens 600 are hinged to the two second hinge columns 701 arranged on the two second filter screens 700.
