A driven gear 111 is fixedly connected to the stirring section 110 and meshes with a driving gear 112. The mixing discharge pipe 301 communicates with the interior of the mixing barrel 101 through the bottom discharge port 1012. The gas acceleration chamber 102 is equipped with a sand discharge port 1021, to which a sand discharge pipe 103 is fixedly mounted. A drive motor 113, which drives the intake fan 107, is also fixedly mounted to the gas acceleration chamber 102 via a drive motor bracket 114.

[0025] A bottom discharge port 1012 is also provided at the bottom of the mixing barrel 101, and a discharge assembly is installed at the bottom discharge port 1012. The discharge assembly includes a mixing discharge pipe 301, an electric valve 302 is fixedly installed on the mixing discharge pipe 301, an acceleration chamber 304 is fixedly installed on the electric valve 302, a mixing discharge port 303 is provided on the acceleration chamber 304, and an accelerating centrifugal impeller 306 is also rotatably installed in the acceleration chamber 304, and the accelerating centrifugal impeller 306 is driven by a sub-gearbox 305 fixedly installed on the acceleration chamber 304.

[0026] A transmission assembly is also fixedly mounted on the mixing drum 101. The transmission assembly includes a main gearbox 201 fixedly connected to the mixing drum 101. An output pulley 202 is fixedly mounted on the intake fan connection panel 106 and is in driving connection with the input shaft of the main gearbox 201 via a first transmission belt 203. The output shaft of the auxiliary gearbox 305 is fixedly connected to the accelerating centrifugal impeller 306. The input shaft of the auxiliary gearbox 305 is in driving connection with the output shaft of the main gearbox 201 via a second transmission belt 204.

[0027] The base 6 is also fixedly mounted with a housing 5, and a top cover 4 is fixedly mounted on the top of the housing 5. The top cover 4 has an air inlet 42 for air intake and a negative pressure collection nozzle 41 for recovery. The base 6 also includes a collection hood 8, which is provided with a connecting nozzle 81. The connecting nozzle 81 is connected to the negative pressure collection nozzle 41 via a pipe. The collection hood 8 is also slidably provided with a sliding tube 71. The sandblasting nozzle 7 is mounted on one end of the sliding tube 71, and the other end of the sliding tube 71 is connected to the sand discharge pipe 103 or the mixed material outlet 303 via a pipe.

[0028] The working principle of a quartz sandblasting machine for preventing sand particles from flying disclosed in the present invention is as follows: quartz sand is poured into a feed barrel 109, and then slides into a mixing barrel 101 through a feed port 1011, and then the drive motor 113 is started. The output shaft of the drive motor 113 drives the air intake fan 107 to rotate. The rotation of the air intake fan 107 generates airflow, which blows toward the surface of the quartz sand in the mixing barrel 101, thereby mixing the quartz sand on the surface with the air (similar to a sandstorm). When the air intake fan 107 rotates, it also drives the air intake fan connection panel 1 06 rotates, and the rotation of the air intake fan connecting panel 106 will drive the centrifugal sand discharge fan 104 to rotate through the connecting frame 105, and the rotating centrifugal sand discharge fan 104 will drive the internal air to rotate, so that the air is thrown to the sand discharge port 1021 under the action of centrifugal force. At the same time, the mixed gas of air and quartz sand in the mixing barrel 101 will enter the centrifugal sand discharge fan 104 through the top discharge port 1013, and then flow to the sand discharge port 1021, and be discharged to the sand blasting nozzle 7 through the sand discharge pipe 103 and the hose, so as to clean the surface of the parts. After the quartz sand hits the surface of the part, it loses kinetic energy. Due to the high-speed rotation of the air intake fan 107, the area above the air intake fan 107 is in a negative pressure state, and air enters through the negative pressure collection nozzle 41 and the air inlet 42. At this time, the pressure in the collection cover 8 will also decrease (the negative pressure collection nozzle 41 is connected to the connecting nozzle 81). If you need to change the adsorption strength of the collection cover 8, you only need to cover the air inlet 42 with a baffle and change the air intake volume of the air inlet 42. At this time, the quartz sand sprayed from the sandblasting nozzle 7 will be collected by the collection cover 8 to prevent it from flying away and reduce the waste of quartz sand.

[0029] According to the process requirements of different parts (when the surface of the object to be cleaned is too greasy or the attachments are difficult to remove, it is determined according to the actual usage and the surface properties of the object to be cleaned), water can also be added to the feed barrel 109, and then flow into the mixing barrel 101 to mix the water with the quartz sand to become wet quartz sand. Similarly, the drive motor 113 is started. The drive motor 113 can drive the input shaft of the main gearbox 201 to rotate (through the output pulley 202 and the first transmission belt 203) while driving the intake fan connection panel 106 to rotate. Then the output shaft of the main gearbox 201 will drive the driving gear 112 to rotate through the third transmission belt 205. The rotation of the driving gear 112 will drive all the driven gears 111 to rotate, and then the stirring part 110 will rotate, and the rotation of the stirring part 110 will stir the quartz sand in the mixing barrel 101 to make it evenly mixed (when no water is added, it can also prevent the quartz sand from clumping). At the same time, the output shaft of the main gearbox 201 will drive the input shaft of the auxiliary gearbox 305 to rotate through the second transmission belt 204, and the output shaft of the auxiliary gearbox 305 will drive the accelerating centrifugal impeller 306 to rotate. At this time, the electric valve 302 is opened, and then the water and quartz sand mixture in the mixing barrel 101 will flow into the accelerating centrifugal impeller 306. Due to the rotation of the accelerating centrifugal impeller 306, the water and quartz sand will be accelerated and thrown into the mixing discharge port 303, and then discharged to the sandblasting nozzle 7 through the hose, so that the wet quartz sand is sprayed onto the surface of the part.
