Description

Technical Field

[0001] This patent relates to the field of shot blasting machine technology, specifically a shot blasting machine. Background Art

[0002] Shot blasting machine is a cleaning tool used in casting, metallurgy, machining and other industries. It is matched with a cleaning chamber to clean castings, forgings and welded parts, remove sand, scale and surface reinforcement on the surface of the workpiece. In the shot blasting equipment industry, shot blasting machine is the most important and critical equipment. The effectiveness of the whole set of shot blasting equipment and the speed of cleaning the workpiece depend on the performance of the shot blasting machine. The shot blasting machine uses a high-speed rotating impeller to throw small steel or iron shots to hit the surface of the parts at high speed, so it can remove the oxide layer on the surface of the parts.

[0003] A shot inlet pipe is embedded on one side of the existing shot blasting machine, which is used to feed the shot into the shot dividing wheel in the shell. However, most of the shot inlet pipes lack a shielding structure. When no steel shots are put in, the internal steel shots are easy to collapse back into the shot inlet pipe. Some shot inlet pipes are also provided with baffles, but the baffles are all single plates. The rapid impact of steel shots on the plate body is easy to reduce the service life of the plate body. For this reason, we propose a shot blasting machine. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This patent provides a technical solution: a shot blasting machine, including a shot blasting machine body 1, a shot outlet is provided at the bottom of the right side wall of the shell of the shot blasting machine body 1, a baffle door 2 is installed in the shot outlet, a base 3 is installed at the bottom of the shot blasting machine body 1, a shot inlet pipe 4 is embedded in the left side wall of the shot blasting machine body 1, an inclined baffle 5 is fixedly installed on the inner side wall of the shot inlet pipe 4, and the number of inclined baffles 5 is four, a sliding hole 6 is provided at the top of the side wall of the shot inlet pipe 4, and a vertical baffle 7 is slidably installed on the inner side wall of the sliding hole 6, and the bottom end of the vertical baffle 7 is attached to the bottom end of the inner side wall of the shot inlet pipe 4;

[0022] The vertical baffle 7 includes a vertical plate 8, a left plate body 9 and a right plate body 12. The side wall of the vertical plate 8 is slidably mounted on the inner wall of the sliding hole 7. The left plate body 9 and the right plate body 12 are both located in the pill inlet pipe 4. The bottom end of the left plate body 9 is attached to the bottom end of the inner wall of the pill inlet pipe 4. The top end of the left plate body 9 is fixedly mounted on the bottom left end of the vertical plate 8. A guide hole 10 is provided in the middle of the left plate body 9. A guide rod 11 is slidably mounted on the inner wall of the guide hole 10. The right end of the guide rod 11 is fixedly mounted on the middle of the left side surface of the right plate body 12. Springs 13 are fixedly mounted on both upper and lower sides of the left side surface of the right plate body 12. The left end of the spring 13 is fixedly mounted on the right side surface of the left plate body 9. A rubber layer 14 is fixedly mounted on the right side surface of the right plate body 12.

[0023] like Figure 4 As shown, the left end of the guide rod 11 is located in the guide hole 10 , which is convenient for extracting the vertical baffle 7 from the sliding hole 6 .

[0024] The right side wall of the shot blasting machine body 1 is connected with a connecting ring 19 through a flange, a motor 20 is installed on the right end of the connecting ring 19, a wheel plate 21 is fixedly installed on the left end of the rotating shaft of the motor 20, a shot-distributing wheel 22 is fixedly installed on the left side of the wheel plate 21, a blade 23 is fixedly installed on the side wall of the wheel plate 21, and an orientation sleeve 24 is fixedly installed on the inner left side wall of the shot blasting machine body 1.

[0025] The directional sleeve 24 is cylindrical, and a window is provided on the top thereof for the steel shot to fly out.

[0026] Specifically, the bottom end of the right plate body 12 does not contact the bottom end of the inner wall of the pill inlet pipe 4 .

[0027] Since the bottom end of the right plate body 12 does not contact the bottom end of the inner wall of the pill inlet pipe 4, it can be avoided that the right plate body 12 contacts the bottom end of the inner wall of the pill inlet pipe 4 when moving leftward to cause obstruction.

[0028] Specifically, the inclined baffle 5 is a flexible steel sheet.

[0029] The flexible steel sheet is equivalent to a shrapnel and is used to cushion the impact force of the steel shot.

[0030] Specifically, a horizontal plate 15 is fixedly installed on the outer left side wall of the shot blasting machine body 1, a hydraulic cylinder 16 is hinged on the top left side of the base 3 through a hinge seat, the top of the piston rod of the hydraulic cylinder 16 is hinged to the bottom of the horizontal plate 15 through a hinge seat, and the right end of the bottom of the outer shell of the shot blasting machine body 1 is hinged to the top of the base 3 through a hinge.

[0031] If the baffle door 2 is opened directly to take out the steel shot at the bottom of the shot blasting machine body 1, the hands may be easily cut by debris and the like. At this time, the shot blasting machine body 1 can be turned over along the hinged position with the base 3 by the hydraulic cylinder 16 to facilitate pouring out the steel shot.

[0032] Specifically, a collecting groove 17 is provided on the top right side of the base 3 , the front-to-back width of the collecting groove 17 is greater than the front-to-back width of the pill outlet, and the collecting groove 17 corresponds to the position of the blocking door 2 .

[0033] Specifically, T-shaped holes 18 are provided at both the front and rear ends of the top left side of the base 3 , and bolts are provided in the T-shaped holes 18 , with the ends of the bolts located in the T-shaped holes 18 .

[0034] The bottom end of the bolt can be screwed into the ground to increase the overall fixing effect, and the end of the bolt is located in the T-hole 18 to prevent the end of the bolt from protruding from the top of the base 3, which can prevent people from accidentally touching the end of the bolt with their feet and causing danger.

[0035] Working principle: remove the top cover on the top of the shot blasting machine body 1, fix the workpiece on the bottom drop line of the top cover, reinstall the top cover and the shot blasting machine body 1, take out the vertical baffle 7 and put the steel shot from the shot inlet pipe 4, the steel shot enters the shot dividing wheel 22 controlled by the motor 20, and the shot dividing wheel 22 rotates synchronously with the blade 23 to give the projectile an initial velocity. The projectile flies out through the top window of the directional sleeve 24 and is thrown onto the high-speed rotating blade 23 outside the directional sleeve 24. After being further accelerated by the blade 23, it is ejected onto the surface of the workpiece to be cleaned above.

[0036] When the steel shots are continuously released in the above process, the released steel shots can be blocked by the inclined baffle 5. When the steel shots are fully released, the vertical baffle 7 can be reinserted into the sliding hole 6. When the steel shots hit the rubber layer 14, the impact force of the steel shots can be reduced through the cushioning effect of the rubber itself and the spring 13, thereby reducing the damage to the overall vertical baffle 7 and improving its service life.

[0037] It should be noted that the equipment structure and drawings of this patent mainly describe the principles of this patent. In terms of the technology of this design principle, the settings of the device's power mechanism, power supply system and control system are not fully described.
