Then, the user needs to open the access door 51 of the dust removing device 4, sleeve the filter bags one by one for the nine brackets 45, pass the filter bags through the round hairbrush 46 while sleeving, then need to fix the filter bags one by one, and then close the open access door 51;

When the grain sorting device is used, a user needs to electrify the electric fan 6, the electric auger 7, the electric conveyor belt 9, the vibration motor 11 and the air pump 57 through controlling the operation panel 54, then grains are conveyed into the grain sorting device 3 through the conveyor belt for conveying the grains, firstly the grains can fall onto the trapezoid grain sorting plate 53 in the grain sorting device 3, the trapezoid structure design of the trapezoid grain sorting plate 53 enables the middle of the trapezoid grain sorting plate 53 to be flatter, in addition, the grains can be accumulated in the middle of the trapezoid grain sorting plate 53 at first and slide into the grain sorting device 3 due to the fact that the trapezoid grain sorting plate 53 has a certain inclination angle, and the grains can slide from the middle to two sides rapidly along with the accumulation of the grains and slide into the grain sorting device 3 along with the accumulation of the trapezoid grain sorting plate 53, so that the grains can be dispersed rapidly and are convenient to screen;

Next, the grains fall out of the grain separating device 3, then enter the inside of the grain sieving shell 10 through the grain inlet 12, the grains entering the inside of the grain sieving shell 10 fall to the upper side of the first screen 16, after the other two vibrating motors 11 are electrified, the two vibrating motors 11 drive the grain sieving device 2 to vibrate integrally, the grain sieving shell 10 and the vehicle-mounted platform 1 can be prevented from vibrating together through the four springs 41, the two vibrating motors 11 drive the grain sieving device 2 to vibrate regularly, then the grains falling onto the first screen 16 vibrate together, and scatter on the upper side of the first screen 16 and move to one side of the first screen 16, and simultaneously the grains fall to the upper side of the second screen 17 through a plurality of first screen holes and a plurality of second screen holes, and impurities larger than the selected grains continue to move to one side of the first screen 16, finally the grains falling onto the second screen 17 are discharged through the two first impurity discharging holes 14, then the grains falling onto one side of the second screen 17 move to one side of the second screen 17, finally the grains falling onto the second screen 17 through the second screen holes 10 and the second screen holes 15 through the first screen holes, and the second screen holes 15 are discharged through the second screen holes, and finally the grains fall to the second screen holes 15 through the second screen holes and the second screen holes;

next, the screened grains fall to the electric conveyor belt 9 through the grain outlet 13, the electrified electric conveyor belt 9 can drive the screened grains to be discharged out of the equipment, in addition, when the screened grains fall from the grain outlet 13, the two electrified electric fans 6 can start to pump the internal air of the dust removing box 42 to the outside, meanwhile, as the dust removing box 42 is sealed, the two electric fans 6 can pump the external air into the dust removing box 42 through the air duct 5, as one end of the air duct 5 is arranged on the upper side of the grain outlet 13, dust or flying impurities can be easily lifted in the falling process of the screened grains, and meanwhile, the dust or the impurities which are easily lifted in the quality can be sucked into the dust removing box 42 through the air duct 5, and through the process, the screened grains can be cleaner to increase the screening effect;

Next, since the partition plate 43 divides the interior of the dust removing box 42 into upper and lower parts, dust or mass easily floats up the impurities, which will first enter the lower part of the interior of the dust removing box 42, through the suction of the two electric fans 6, the lower part of the interior of the dust removing box 42 will pass through the nine filter bags, and through the nine circular through holes 44, enter the upper part of the interior of the dust removing box 42, and then the two electric fans 6 will be sucked to the outside, while dust or mass easily floats up the impurities will adhere to the nine filter bags, and more dust or mass easily floats up the impurities will adhere to the increase of time, at this time, the impurities need to be removed, the user needs to turn off the power on of the two electric fans 6 by controlling the operation panel 54, the user can give the second pneumatic solenoid valve by controlling the operation panel 54, the high-pressure gas in the air pump 57 enters one end of the two air cylinders 48 through the hose, the two push rods extend out of the two air cylinders 48, the two air cylinders 48 can drive the connecting frame 47 to move, the connecting frame 47 can drive the nine round brushes 46 to move, the nine round brushes 46 can respectively enable dust or mass on the filter bag to float impurities easily, the dust or mass can fall into the bottom of the dust removing box 42 after the impurities fall off easily, then the electric auger 7 brings out of the dust removing box 42, in addition, a user can control the operation panel 54 to give the first air solenoid valve, the high-pressure gas in the air pump 57 enters the connecting tank 49 through the hose, then the connecting tank 49 distributes the high-pressure gas to the nine air pipes 50, since one ends of the nine air pipes 50 are respectively arranged on the upper sides of the nine round through holes 44, the high-pressure gas sprayed out through the nine air pipes 50 enters the nine brackets 45, the high-pressure air can wash away the dust or the impurities which are more easily floating and attached to the nine filter bags, and after the dust or the impurities which are more easily floating and attached to the filter bags are cleaned, a user can continue to use the dust removing device 4 according to the operation.
