Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning device for a hook-type shot blasting machine. Background Art

[0002] Shot blasting machine, also known as sandblasting machine, is a casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. It can remove sand, core and clean castings. It can also be used to remove burrs, diaphragms and rust. Compared with other surface treatment equipment, it is faster and more effective, so it is widely used in various metal casting and steel production industries.

[0033] The steel shot baffle 3 will block the steel shots inside the shot blasting chamber 2 inside the shot blasting chamber 2, and when the fan 6 starts to run, the gas containing metal dust inside the shot blasting chamber 2 will be sucked into the inside of the fan 6 through the steel shot baffle 3, the installation box 4 and the exhaust port 5, and will come to the outside of the shot blasting chamber 2 along the exhaust port 7, the connecting pipe 8, the installation box 9 and the activated carbon block 11.

[0039] When the first motor 18 is running, the circular shaft 19 will start to rotate as a whole.

[0040] Among them, the outer surface of the circular shaft 19 is fixedly sleeved with a cam 20 located inside the No. 1 classification box 13, the top of the outer surface of the cam 20 is movably connected to the lower surface of the connecting plate 16, and the left surface of the cam 20 is movably connected to the inner surface of the No. 1 classification box 13.

[0041] When the cam 20 rotates, the entire connecting plate 16 starts to rotate and vibrate regularly around the fixed shaft 15 driven by the cam 20 .

[0042] Among them, the bottom of the inner surface of the No. 1 classification box 13 and the No. 2 classification box 14 are movably connected to the collection box 27, the upper surfaces of the No. 1 classification box 13 and the No. 2 classification box 14 are fixedly connected to the cover plate 21, the upper surface of the cover plate 21 is provided with a movable groove 22, the inner surface of the movable groove 22 is movably connected to the closing block 26, the outer surface of the closing block 26 is movably connected to the inner surface of the No. 1 classification box 13, and the lower surface of the closing block 26 is movably connected to the upper surface of the filter plate 17.

[0043] When the closing block 26 starts to move along the inner surface of the movable groove 22 toward the inside of the second classification box 14, the complete steel shots above the filter plate 17 will be pushed into the inside of the second classification box 14 by the closing block 26, thereby realizing the classification and collection of the complete steel shots.

[0044] Among them, the left and right ends of the upper surface of the cover plate 21 are fixedly connected with the mounting plate 23, the right surface of the mounting plate 23 is fixedly mounted with the No. 2 motor 24, the other end of the output shaft of the No. 2 motor 24 is fixedly sleeved with a lead screw 25, the left end of the lead screw 25 passes through the mounting plate 23 and the closing block 26 in sequence and extends to the left side of the mounting plate 23, the outer surface of the lead screw 25 and the inner surface of the mounting plate 23 are movably sleeved, and the outer surface of the lead screw 25 and the inner surface of the closing block 26 are threadedly sleeved.

[0046] The working principle and use process of this utility model:

[0047] When the shot blasting operation begins in the shot blasting room 2, the operator starts the fan 6. As the fan 6 runs, the fan 6 extracts the gas containing metal dust in the shot blasting room 2. The gas is drawn into the fan 6 after passing through the steel shot baffle 3, the installation box 4 and the air suction port 5, and then goes along the exhaust port 7, the connecting pipe 8, the installation box 9 and the activated carbon block 11 to the outside of the base 1 as a whole. In this process, the activated carbon block 11 adsorbs the metal dust in the gas, thereby ensuring the air quality in the working environment and avoiding the influence of metal dust on the human body.

[0048] When the shot blasting operation is completed, the steel shots inside the shot blasting chamber 2 will be concentrated on the upper surface of the filter plate 17 along the shot guide groove 12. At this time, the operator starts the No. 1 motor 18. The operation of the No. 1 motor 18 will cause the round shaft 19 and the cam 20 to start rotating. At this time, the rotation of the cam 20 will drive the connecting plate 16, so that the connecting plate 16 as a whole starts to rotate and vibrate with the fixed shaft 15 as the axis. In this process, the broken steel shots above the filter plate 17 will fall into the bottom of the connecting plate 16 through the gap of the filter plate 17. When the collection of the broken steel shots is completed, the operator starts the No. 2 motor 24. As the No. 2 motor 24 runs, the lead screw 25 starts to rotate. At this time, the closing block 26 will start to move along the inner surface of the movable groove 22 toward the No. 2 classification box 14 driven by the lead screw 25. In this process, the complete steel shots above the filter plate 17 will be pushed into the interior of the No. 2 classification box 14. As a result, the complete steel shots and the broken steel shots will be collected in the two collection boxes 27 respectively, thereby realizing the classification and processing function of the steel shots.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
