As a further scheme of the invention, the upper end of the belt 41 is slidably connected with a material guide plate 43, and the material guide plate 43 is fixedly connected with the upper end of the dust removing section 2.
During operation, the grains carried in the material conveying box 42 are conveyed to the height same as that of the material guide plate 43 through the belt, and then the grains carried in the material conveying box 42 are poured into the material guide plate 43 for secondary impurity removal and drying.
The working principle is as follows: the invention is in actual operation: the grain is poured out of the upper end of the dust removal section 2 into the dust removal section 2, the dust removal assembly in the dust removal section 2 carries out rotary vibration processing on the grain, the density of the stones is higher than that of the grain, the stones mixed in the grain are positioned at the lower end of the grain in the vibration process of the dust removal assembly, and the grain is positioned at the upper end of the stones, so that the grain and the stones are layered; then, by continuously injecting grain into the dust removing component, the grain in the dust removing component is continuously increased, the grain which is well screened and removed dust and is arranged on the upper layer of the dust removing component can emerge from the upper end of the dust removing component, then the grain can fall into the first drying section 3 along the blanking frame, and simultaneously the air heater 6 is started, the grain which is well removed dust enters the first drying section 3 to be primarily dried, then the grain enters the feeding section 4, at the same time, the hot air blown by the air heater 6 enters the second drying section 5 through the vent pipe 8 to be discharged through the air outlet pipe 7, at the same time, the grain can enter the second drying section 5 from the feeding section 4 to be dried again, and simultaneously, as the amount of the grain screened by the dust removing component is increased, the stones accumulated in the lower end of the dust removing component also become more, the weight of the stones becomes larger, in the rotating process of the dust removing component, due to the action of centrifugal force, the stones are gradually accumulated at the groove of the dust removing component, and fall from the dust removing component after the groove of the dust removing component is full of the stones, in the falling process of the stones, because the mass of the stones is larger than that of the grains, the inertia generated by the stones is also larger than that of the grains, so that the parabola generated when the stones fall from the dust removal component is farther than that of the grains, then the stones are collected by the dust removal component, a little grain mixed in the stones continuously falls into the first drying section 3 for primary drying, then the grain enters the feeding section 4, at the same time, the hot air blown by the hot air blower 6 enters the second drying section 5 through the vent pipe 8 and is discharged through the vent pipe 7, at the same time, the grain also enters the second drying section 5 from the feeding section 4 to be dried again, then the dried grains fall into a transportation assembly, the transportation assembly transports the grains to a dust removal section 2, and the grains are subjected to dust removal and drying again; by using the dust removal component, the problems that in the traditional process, when grains are doped with stones with the same size as the grains, the stones in the grains cannot be screened out by using a common screen, and the eating of the grains is influenced because the stones are mixed in the grains are avoided; the dust removal assembly ensures that stones similar to grains in size can be screened out through the dust removal assembly uninterruptedly and quickly.
