As shown in fig. 8, the supporting wheel assembly 14 includes a supporting wheel 141, a guide shaft 142, an end stop 143, a cushion 144, a linear bearing 145 and a connecting plate 146, the top of the supporting wheel 141 is connected to the guide shaft 142, the guide shaft 142 passes through the linear bearing 145, the linear bearing 145 is mounted on the lower fixing plate 12, the end stop 143 is mounted on the top of the guide shaft 142, the cushion 144 is strung on the guide shaft 142 below the end stop 143, and one end of the connecting plate 146 is connected to the bottom of the bellows 15 along the connecting end at the side of the supporting wheel 141. Because the invention is installed on the shot blasting machine trolley, the bottom supporting wheel component 14 is not stressed, when the shot blasting device works, the guide shaft 142 slides in the linear bearing 145, the supporting wheel 141 falls on the road surface under the action of gravity, the supporting wheel components 14 at different positions can adjust the positions adaptively according to the different distances from the ground, the distance between each part of the corrugated pipe 15 and the ground is kept constant, when the device does not work, the guide shaft 142 slides downwards, the top shaft end baffle 143 clamps the position of the guide shaft 142, the supporting wheel component 14 cannot fall off, the buffer cushion 144 installed below the shaft end baffle 143 is made of elastic materials, and the shaft end baffle 143 cannot generate impact with the buffer cushion 144 in the process of sliding the guide shaft 142 downwards.
The working principle of the invention is as follows: the shot materials enter the feeding assembly 23 from the storage bin 21 through the feeding pipeline 22, the shot materials in the feeding assembly 23 obtain a larger initial speed, the shot materials reach the throwing opening 25 through the shot blasting chamber 24, the shot materials are evenly thrown to the road surface to be treated, impact is generated on the road surface, the roughening treatment is carried out on the road surface, meanwhile, surface impurities are removed, the shot materials impacting the ground bounce to the recovery separation component 3, the impurities and dust are mixed with the shot materials and are sucked into the separation chamber 33 due to the fact that the opening at the bottom of the recovery separation component 3 is provided with negative pressure, the separated impurities are temporarily stored in the impurity recovery tank 35, the shot materials are recovered into the shot blasting component again for secondary utilization, and the flying dust enters the dust removal component 4 for filtering and collection. The dust-containing gas enters the dust remover from the inlet of the dust removing component 4 along the tangential direction and then rotates downwards along the outer wall, and the downward rotating gas flow is called as an outer vortex. After the outer vortex reaches the bottom of the cone, the outer vortex turns upwards and rotates upwards along the axis, and finally the outer vortex is discharged from the exhaust pipe 42, when the airflow rotates, the dust is thrown to the outer wall under the action of centrifugal force, and the dust reaching the outer wall falls into the ash bucket 45 along the wall surface under the combined action of the lower vortex airflow and gravity.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described above, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
