TECHNICAL FIELD
[0001] Embodiments of the present disclosure relate to the technical field of shot blasting machine, in particular, to an automatic adjusting type steel structure member shot blasting machine. BACKGROUND
[0002] The automatic adjusting type steel structure shot blasting machine is an advanced shot blasting equipment, which can automatically adjust the working parameters according to the preset conditions or real-time feedback to achieve better treatment effect and production efficiency. It is mainly used in steel plate, metal structure, machine tool bed, steel (cast iron) products, net rack, engineering machinery and bridge manufacturing industry. The shot blasting machine uniformly hits the shot on the surface of the steel in the original state through the high-speed movement of the shot blasting machine, so as to realize the cleaning, rust removal and other purposes of the steel, so that the steel obtains uniform and consistent metal luster, so as to improve the finishing quality and corrosion prevention effect of the steel.
[0003] The working principle of the automatic adjusting type shot blasting machine is that first, the control system sets various process parameters, the shot blasting motor drives the shot distribution wheel to rotate at high speed through the transmission mechanism, the shot flows into the shot distribution wheel under the action of gravity to realize acceleration, and then under the action of centrifugal force, the shot is thrown out of the shot distribution wheel window into the directional sleeve, and then thrown out of the directional sleeve window, picked up by the high-speed rotating blade, and continuously accelerated along the length direction of the blade until thrown out. The thrown shot forms a certain fan-shaped flow, impacts the surface of the steel structure member, and plays a cleaning or strengthening role. Finally, the rebounded shot and impurities formed by the shot blasting are respectively affected by inertia and negative pressure to enter the recycling and separating system through the high-pressure rebound chamber. Under the action of the recycling and separating system, the shot and the dust are separated, the shot is recycled back to the storage hopper, and the dust is collected by the dust collector.

Therefore, the flying dust around can be collected.
[0059] With reference to Figure 4 With reference to Figure 5The limiting mechanism comprises a first limiting groove 16, a second limiting groove 17, a limiting block 18 and a relative moving mechanism. The first limiting groove 16 is arranged on the opposite two side walls of the mounting groove. The second limiting groove 17 is arranged on the opposite two side walls of the mounting block 15. The limiting block 18 is slidingly arranged in the second limiting groove 17. The limiting block 18 is matched with the first limiting groove 16 in shape. The relative moving mechanism is arranged on the mounting block 15 and is used for driving the two limiting blocks 18 to move relatively. The relative moving mechanism comprises a first cavity, an adjusting disc 21 and a hand wheel 23. The first cavity is arranged in the mounting block 15. Two adjusting blocks 19 are slidingly arranged in the first cavity. A limiting rod 20 is fixedly arranged between the adjusting block 19 and the adjacent limiting block 18. The adjusting disc 21 is rotationally arranged in the first cavity. Two rotating shafts are rotationally arranged at the eccentric position of the adjusting disc 21. An adjusting rod 22 is fixedly arranged on the rotating shaft. The adjusting rod 22 is hingedly connected between the end, away from the rotating shaft, of the adjusting rod 22 and the adjacent adjusting block 19. The hand wheel 23 is rotationally arranged on the mounting block 15. A driving rod is fixedly arranged between the hand wheel 23 and the adjusting disc 21. A supporting spring 24 is sleeved on the limiting rod 20. The two ends of the supporting spring 24 are fixedly connected with the groove bottom of the second limiting groove 17 and the limiting block 18, respectively. Anti-skid lines are fixedly arranged on the side wall of the hand wheel 23. Rubber pads are fixedly arranged on the side wall of the limiting block 18. Specifically, the rotation of the hand wheel 23 drives the driving rod and the adjusting disc 21 to rotate. Then, the rotating shaft and the adjusting rod 22 can pull the adjusting block 19 to move relatively. Meanwhile, the limiting rod 20 can pull the limiting block 18 to move relatively. Thus, the limiting and unlocking of the mounting block 15 can be realized through the cooperation of the limiting block 18 and the first limiting groove 16. Thus, it is convenient to clean the rust and impurities in the collecting drawer 14.
[0060] The working principle is that, in use, the operator can place the steel structure on the roller conveyor 4 and drive the steel structure to move below the shot blasting machine body 1 through the working belt of the roller conveyor 4, so that the steel structure can be cleaned by the shot blasting machine body 1. During the shot blasting and cleaning process, the cleaned shot and rust impurities can fall into the screening cylinder 7 under the action of gravity, and then the shot and impurities are screened by the screening plate. After screening, the pipe control valve can be opened, and the impurities are recycled through the recovery pipe 10 to realize the recycling of the shot. During the screening process, the operator controls the first motor 13 to work, and the working of the first motor 13 can drive the stirring column 12 to rotate, and at the same time, the stirring column 12 drives the stirring rod to move, so that the stirring rod can stir the shot and rust impurities, thereby improving the screening efficiency of the rust impurities by the screening plate. The screened rust impurities can fall into the collection drawer 14 under the action of gravity for collection. At the same time, the operator controls the fan 27 to work, which can generate negative pressure in the dust collecting box 26, so that the dust can be screened by the filter plate in the filter port 25. Then the dust can be collected by the dust collecting box 26, so as to facilitate the collection of the dust around. After the recycling is completed, the operator can rotate the hand wheel 23, which drives the driving rod and the adjusting disc 21 to rotate through the rotation of the hand wheel 23. In turn, the adjusting block 19 can be relatively moved by the rotation of the shaft and the adjusting rod 22, and the limiting block 18 can be relatively moved by the limiting rod 20, so that the limiting and unlocking of the mounting block 15 can be realized by the cooperation of the limiting block 18 and the first limiting groove 16, thereby facilitating the cleaning of the rust impurities in the collection drawer 14.
