[0025] In operation, the grain suction machine is moved to a suitable position, and the grain is sucked into the suction pipe 12 through the grain suction port 121 in cooperation with the external equipment. Under the guidance of the guide plate 122, the grain drives the impeller 123 to rotate, and the suction speed is positively related to the rotation speed of the impeller. The rotation of the impeller 123 drives the valve push rod 1231, which drives the cone valve 1232 to stretch the spring rod 1234, so that the air guide pipeline 124 is connected. The external air pump equipment blows air into the air guide duct 1241. The gas pushes the piston rod 132 to move downward. When the grain is slowly sucked, the rotation speed of the impeller 123 is slow, the single air intake is small, the gas pressure is small, the piston rod 132 is compressed by the air pressure spring 1321 to move downward, and the gas is discharged when it reaches the air outlet duct 1242.

This process drives the filter 13 to move, extrudes the gas in the grain suction tank 11, realizes the back blowing cleaning of the filter 13, and ensures the filtering effect. The dust falls to the air duct plate 113 and is cleaned through the dust removal port.

[0026] In summary, through the setting of the grain suction structure 1, when the grain is quickly sucked, the rotation speed of the impeller 123 is fast, the valve push rod 1231 is continuously pushed, the cone valve 1232 is continuously separated from the valve seat 1233, the gas in the lifting air duct 1243 continuously pushes the piston rod 132, the air outlet duct 1242 is always open, the filter 13 is at the lowest position, the air cone 131 penetrates the air duct plate 113, and the grain suction machine is in full power grain suction state, which ensures the grain suction efficiency; when the grain is slowly sucked, the rotation speed of the impeller 123 is slow, the single air intake is small, the gas pressure is small, the piston rod 132 is compressed by the air pressure spring 1321 to move downward, and the gas is discharged when it reaches the air outlet duct 1242. Subsequently, the piston rod 132 resets to block. This process drives the filter 13 to move, extrudes the gas in the grain suction tank 11, realizes the back blowing cleaning of the filter 13, and ensures the stable operation of the system, avoids frequent shutdown and cleaning due to smoke dust blocking the filter 13, saves time, and improves the working efficiency of the grain suction machine.

[0027] Meanwhile, the contents not described in detail in the specification are all prior art known to those skilled in the art.

[0028] Working principle: when working, first move the grain suction machine to the appropriate position, then cooperate with the external grain pumping equipment, the grain is pumped into the suction pipe 12 through the grain suction port 121, and the grain and gas entering the suction pipe 12 will change the direction of movement under the guidance of the inclined guide plate 122, thereby driving the impeller 123 to rotate, at this time, the speed of the suction grain and airflow is positively related to the rotating speed of the impeller 123, the faster the speed, the faster the impeller 123 rotates, the rotating impeller 123 pushes the valve push rod 1231 with the blade, one end of the valve push rod 1231 inserted into the space where the impeller 123 is located is semispherical, which makes the sliding contact between the valve push rod 1231 and the impeller 123 blade more smooth, after the valve push rod 1231 is pushed, the other end pushes the cone valve 1232 to stretch the spring rod 1234 along the wall of the air guide pipeline 124, so that it moves away from the valve seat 1233, with the cone valve 1232 and the valve seat 1233 gradually moving away, the inside of the air guide pipeline 124 is temporarily connected at this time, the external air pump equipment connected with the upper end of the air guide pipeline 124 starts to work, and the air is pumped into the air guide air duct 1241 through the air guide pipeline 124, and the air reaches the lifting air duct 1243, pushing the piston rod 132 to move down, if it is in the slow grain pumping state, the gas pressure entering the lifting air duct 1243 is relatively small (because the rotating speed of the impeller 123 is relatively slow, the valve push rod 1231 and the cone valve 1232 will only make the cone valve 1232 and the valve seat 1233 separate for a short time, so the amount of gas entering the lifting air duct 1243 at a time is small), which will gradually push the piston rod 132 to compress the air pressure spring 1321 to move down, when the piston rod 132 moves to the position of the air outlet air duct 1242, the gas is discharged from the air outlet air duct 1242, and then, under the reset action of the air pressure spring 1321, the piston rod 132 moves upward to reset, resealing the air outlet air duct 1242, in this process, the upward and downward movement of the piston rod 132 drives the filter 13 to move synchronously, and the filter 13 is pressed under the rapid reset action of the air pressure spring 1321, the gas above the inside of the grain suction tank 11 is extruded, the dust adsorbed on the filter 13 is blown off in the opposite direction, which will fall on the surface of the air duct plate 113, and the dust falling on the surface of the air duct plate 113 can be cleaned through the dust removal port at the rear of the side of the grain suction tank 11, in the slow grain pumping process, the blowback cleaning process continues, ensuring the filtering effect of the filter 13;

[0029] If it is fast grain extraction, the rotating speed of the impeller 123 is faster, the impeller 123 continuously pushes the valve push rod 1231, the conical valve 1232 is continuously separated from the valve seat 1233, then the gas entering the lifting air duct 1243 continuously pushes the piston rod 132, the gas outlet air duct 1242 is in a normally open state, and the filter 13 is always in the lowest position under the driving of the piston rod 132, then the filter 13 synchronously drives the air cone 131 to move downward, the downward air cone 131 penetrates the air duct plate 113, the air duct plate 113 is fully opened, then the grain suction machine is in the full power grain extraction state, and the high-speed grain extraction operation is carried out.
