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 100, the tank 100 forms an accommodating chamber 110 for accommodating sand particles 800, the tank 100 is provided with a sand outlet 120 communicated with the accommodating chamber 110; the sand blasting pipeline 200 is arranged on the outer side of the tank body 100, and one end of the sand blasting pipeline 200 is connected with the tank body 100 and is arranged corresponding to the sand outlet 120; a first pipeline 300, wherein the air outlet end of the first pipeline 300 extends into the tank 100, and the air outlet end of the first pipeline 300 is arranged at a distance from the inner wall of the tank 100 and corresponds to the sand outlet 120; and the air source device is used for supplying air to the first pipeline 300, and the air inlet end of the first pipeline 300 is connected with the air source device.
In the sand blasting machine shown in fig. 1, the air outlet end of the first pipeline 300 is embedded in the sand 800 in the accommodating cavity 110 and is close to the sand outlet 120, the air source device supplies air to the first pipeline 300, the air with certain air pressure is ejected from the air outlet end of the first pipeline 300, and the sand 800 at the position of the sand outlet 120 enters the sand blasting pipeline 200 from sand outlet under the driving of self gravity and air pressure, so that compared with the traditional mode that the first pipeline 300 applies pressure to the whole sand 800 in the tank 100, the probability of blockage of the sand 800 is reduced.
Generally, a tank 100 of a blasting machine is filled with sand 800, and a first pipeline 300 sends gas with certain pressure into the tank 100, so that the sand 800 flows out of a sand outlet 120 in a pneumatic driving mode and combines the self gravity of the sand 800 and is sprayed out through a blasting pipeline 200. In this way, the air outlet end of the first pipeline 300 is located on the upper side of the sand grains 800, that is, after the first pipeline 300 conveys the air into the tank 100, the air is gathered above all the sand grains 800, and at this time, the pressure of the air applies pressure to the whole sand grains 800, so that the sand grains 800 are easily blocked at the sand outlet 120, and cannot flow out normally, and the continuous flow of the sand grains 800 cannot be maintained, and the technical effect of sand blasting cleaning cannot be guaranteed.
In the sand blasting machine shown in fig. 1, the air outlet end of the first pipeline 300 not only extends into the accommodating cavity 110 of the tank 100, but also is close to the sand outlet 120, after sand grains 800 are loaded, the air outlet end of the first pipeline 300 is embedded in the sand grains 800, at this time, when air with certain pressure enters, only the sand grains 800 near the sand outlet 120 are pressed, and the sand grains 800 flow out from the sand outlet 120 under the driving of air pressure and the action of self gravity, so that compared with the mode of applying the whole sand grains 800, the conditions such as blockage are not easy to occur.
In fig. 1, the sand outlet 120 is disposed at the lower side of the tank 100, and the air outlet of the air outlet end of the first pipeline 300 is disposed downward and opposite to the sand outlet 120, and has a certain distance, which is at least larger than the grain size of more than one sand 800.

The sand 800 is only one kind of abrasive, is not limited to the sand 800, any existing abrasive capable of being used for sand blasting cleaning can be adopted, and different types and specifications of the sand 800 can be selected according to the type of a workpiece to be processed; in addition, the abrasive can also be a combination of sand 800 and a liquid such as water, and the combination can be selected and configured according to needs, which is not described in detail here.

The air outlet end of the second pipeline 400 is communicated with the sand blasting pipeline 200, and the gas with certain pressure in the second pipeline 400 further applies force to the sand grains 800 in the sand blasting pipeline 200 to eject the sand grains 800. However, in practical use, the first pipeline 300 and the second pipeline 400 usually share the same air source device, in this case, the air pressure in the first pipeline 300 and the second pipeline 400 is practically the same, which makes the air pressure in the accommodating chamber 110 of the tank 100 and the air pressure in the blasting pipeline 200 into which the second pipeline 400 extends equal or nearly equal, and at this time, the sand 800 is not easy to flow out, which is actually equivalent to that the sand 800 flows out by gravity more, and the driving action of the air pressure is very weak. In the embodiment, the air pressure of the first pipeline 300 is greater than the air pressure of the second pipeline 400, so that an air pressure difference is formed between the accommodating cavity 110 of the tank 100 and the inside of the sand blasting pipeline 200, sand blasting is smoothly performed by using the air pressure difference, blocking is avoided, and the technical effect of blasting is further improved.
