Sealing drum cover plate is provided with the top of sealing drum, there is gap between sealing drum and crushing wall, dust ring is provided with the gap, prevented
Konisphere is sleeved on the periphery of sealing drum, also there is gap between dust ring and crushing wall, on the arm support of described frame respectively
The first air-vent is provided with, the first air-vent is distributed along the axial direction of arm support, and the first described air-vent prolongs from the circumferential wall of frame
The center for reaching the inner end of arm support extends vertically upwards out the inner end of arm support, the top connection sealing of the inner end of arm support again
Cylinder, is also equipped with four the second air-vents in the circumferential wall of sealing drum, the second air-vent and the first air-vent are corresponded, and second
Air-vent is distributed along the axis of the circumferential wall of sealing drum, and the second air-vent includes the second air-vent being connected with the first air-vent
Rake, and second be connected above the second air-vent rake and with the top of the second air-vent rake is breathed freely
Hole vertical portion, the top of the second air-vent vertical portion is located at the lower section of sealing drum cover plate, on the sealing drum below sealing drum cover plate
Venthole is additionally provided with, venthole is connected and extends obliquely downward to outside sealing drum with the top of the second air-vent vertical portion
Portion, the gas outlet of venthole is located at the top of dust ring.
The bottom of crushing wall sets fluted, and the longitudinal section shape of groove is inverted U-shaped, the top of described sealing drum
Portion is arranged in the groove of crushing wall.
Good effect of the present utility model is：Simple structure, convenient processing and manufacture, sealing drum and frame circumferencial direction are opened up
4 air-vents, are incorporated into outside clean air the inside of equipment, using the effect of pressure by between crushing wall and sealing drum
Gap in dust thoroughly excluded from inside from all directions, reach the dust-proof of more preferable effect.

Specific embodiment
As shown in Fig. 1 to 5, a kind of gyratory crusher with positive pressure dust-proof structure, including disintegrating machine frame 1, frame 1
Inside circumference on be uniformly provided with four arm supports of transverse direction 6, sealing drum 2 is installed on the inner end of arm support 6, sealing drum 2
The top surface of the inner end of bottom and arm support 6 is in close contact, and the top of sealing drum 2 is connected with sealing drum cover plate 4, the top of sealing drum 2
Portion is also associated with crushing wall 5, and crushing wall 5 is distributed in the periphery of sealing drum 2, and groove 7, groove 7 are left in the bottom of crushing wall 5
Longitudinal section shape be inverted U-shaped, the top of sealing drum 2 is embedded in the groove of crushing wall, sealing drum 2 and crushing wall 5
Groove between have gap, dust ring 3 is provided with the gap, dust ring 3 is sleeved on the periphery of sealing drum 2, the He of dust ring 3
Also there is gap between crushing wall 5, the first air-vent 8 is respectively equipped with the arm support 6 of described frame, the first air-vent 8 is along arm support
Axial cross direction profiles, the center that the first air-vent 8 extends to the inner end of arm support from the circumferential wall of frame is prolonged vertically upward again
Stretch out the inner end of arm support, the top connection sealing drum 2 of the inner end of arm support 6 also is provided with four the in the circumferential wall of sealing drum 2
Two air-vents, the second air-vent and the first air-vent are corresponded, and the second air-vent divides along the axis of the circumferential wall of sealing drum 2
