As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to FIG. 1 , a sand blasting machine includes a tank body 100 . The tank body 100 forms a accommodating cavity 110 for accommodating sand particles 800 , and the tank body 100 is provided with a sand outlet 120 communicating with the accommodating cavity 110 ; 200, the sandblasting pipeline 200 is arranged on the outside of the tank body 100, one end of the sandblasting pipeline 200 is connected with the tank body 100, and is set corresponding to the sand outlet 120; the first pipeline 300, the air outlet of the first pipeline 300 The end extends into the tank body 100, the gas outlet end of the first pipeline 300 is arranged at a distance from the inner wall of the tank body 100, and is arranged corresponding to the sand outlet 120; and an air source device, which is used to supply the first pipeline 300 supplies air, and the intake end of the first pipeline 300 is connected to the air source device.

In the sand blasting machine shown in FIG. 1 , the gas outlet end of the first pipeline 300 is buried in the sand grains 800 in the accommodating chamber 110 and is close to the position of the sand outlet 120 . The gas source device supplies gas to the first pipeline 300 , and there is a certain air pressure. The gas is ejected from the gas outlet end of the first pipeline 300, and the sand 800 at the position of the sand outlet 120 is driven by its own gravity and air pressure from the sand outlet into the sandblasting pipeline 200. Compared with the traditional first pipeline 300, the The overall pressure of the sand grains 800 within 100 reduces the probability of the sand grains 800 being blocked.

Generally, the tank body 100 of the sandblasting machine is equipped with sand grains 800, and the first pipeline 300 feeds gas with a certain pressure into the tank body 100, so that the sand grains 800 are driven by air pressure and combined with the gravity of the sand grains 800 to be released from the outlet. The sand outlet 120 flows out and is sprayed out through the sand blasting pipeline 200 . In this way, the gas outlet end of the first pipeline 300 is on the upper side of the sand grains 800, that is, after the first pipeline 300 transports the gas into the tank 100, the gas converges above all the sand grains 800. At this time, The pressure of the gas exerts pressure on the whole sand grains 800, so that the sand grains 800 are easily blocked at the position of the sand outlet 120, so that the sand grains 800 cannot flow out normally, and the continuous flow of the sand grains 800 cannot be maintained, so that the technical effect of sandblasting cannot be guaranteed. .

In the sand blasting machine shown in FIG. 1 , the gas outlet end of the first pipeline 300 not only extends into the accommodating cavity 110 of the tank body 100 , but also the gas outlet end is close to the sand outlet 120 . The gas outlet end of the road 300 is buried in the sand grains 800. At this time, when the gas with a certain pressure enters, only the sand grains 800 near the sand outlet 120 are pressurized. These sand grains 800 are driven by the air pressure and under the action of their own gravity. Outflow from the sand outlet 120 is less likely to cause clogging compared to the method of applying the whole sand 800 .

In FIG. 1 , the sand outlet 120 is provided on the lower side of the tank body 100 , the air outlet of the gas outlet end of the first pipeline 300 is arranged downward, and is arranged directly opposite the sand outlet 120 , and there is a certain distance, and the distance is at least greater than one The grain size of the above sand grains is 800.

Further, the detachable connection between the sandblasting pipeline 200 and the tank body 100 can be done by means of screw connection, or by way of butt joint, etc., which will not be repeated here.

The gas outlet end of the second pipeline 400 communicates with the sandblasting pipeline 200 , and the gas with a certain pressure in the second pipeline 400 further exerts force on the sand particles 800 in the sandblasting pipeline 200 , so that the sand particles 800 are ejected. However, in actual use, the first pipeline 300 and the second pipeline 400 usually share the same air source device. In this case, the air pressures in the first pipeline 300 and the second pipeline 400 are actually the same, so The air pressure in the accommodating cavity 110 of the tank body 100 and the air pressure in the sandblasting pipeline 200 into which the second pipeline 400 extends are equal or nearly equal. At this time, the sand grains 800 are not easy to flow out, which is actually equivalent to the sand grains 800 relying more on gravity. outflow, and the driving effect of air pressure is very weak. In this embodiment, by making the outlet pressure of the first pipeline 300 greater than the outlet pressure of the second pipeline 400, it is ensured that an air pressure difference is formed between the accommodating cavity 110 of the tank body 100 and the inside of the sandblasting pipeline 200, thereby utilizing the air pressure. The difference is that the sandblasting can be sprayed out more smoothly, avoiding the occurrence of clogging, and further improving the effect of spraying technology.
