[0027] Further, by opening dust extraction pump 111, the inside of dust tank 11 is pumped, so that negative pressure is generated in the inside of dust tank 11, dust floating in the inside of processing box 1 is uniformly sucked into the inside of dust tank 11 in cooperation with dust extraction duct one 112 and dust extraction duct two 113, dust floating to outside along feed inlet 1 and discharge port 3 is prevented. Embodiment
[0028] As Figures 1-5 As shown, on the basis of embodiment 1, the utility model provides a kind of technical scheme: preferably, the left and right outer surfaces of processing box 1 are fixedly installed with clamping support 121 on the two sides of through port, collecting box 12 is movably inserted in the inside of clamping support 121, clamping block 122 is fixedly installed on the two sides of the outer surface of collecting box 12, clamping block 122 is movably inserted in the two sides recesses of clamping support 121, screening unit includes filter screen one 13 fixedly installed on the left inner wall of processing box 1, the other end bottom of filter screen one 13 is fixedly installed with inclined plate one 14, the other end of inclined plate one 14 extends at the left through port of processing box 1, filter screen two 15 is fixedly installed on the left inner wall of processing box 1 below inclined plate one 14, the other end bottom of filter screen two 15 is fixedly installed with inclined plate two 16, the other end of inclined plate two 16 extends at the right bottom through port of processing box 1.
[0029] Furthermore, the grain feed inlet 2 is located inside the processing box 1. The grain first comes into contact with the filter screen plate 13, which filters the grain and separates the impurity particles. The filter screen plate 13 is tilted, causing it to roll continuously towards the tilted end and surge along its tilting direction to the top of the filter screen plate 2 15. The mesh diameter of the filter screen plate 2 15 is smaller than that of the filter screen plate 13, thus enabling secondary filtration. During the two screenings, the impurity particles fall onto the tops of the tilted plates 14 and 2 16, respectively, which transport the impurity particles to the inside of the collection box 12. Example
[0030] like Figures 1-5 As shown, based on embodiments 1-2, this utility model provides a technical solution: preferably, the drying unit includes an installation groove 17 opened at the top of the processing box 1 and at the bottom of the inclined plate 14, and a heating tube 18 is fixedly installed inside the installation groove 17.

[0033] like Figures 1-5 As shown, during use, the grain to be processed is placed inside the processing box 1 along with the feed inlet 2. The grain first contacts the filter screen 13, which filters it, separating impurity particles. The filter screen 13 is tilted, causing it to continuously roll towards the tilted end and surge along its tilting direction to the top of the filter screen 15. The mesh diameter of the filter screen 15 is smaller than that of the filter screen 13, thus enabling secondary filtration. During the two screenings, the impurity particles fall onto the tilted end of the filter screen. The tops of inclined plate 14 and inclined plate 16 transport impurity particles to the inside of collection box 12. At the same time, during the screening process, the heating pipe 18 is turned on to generate a heat source, which facilitates the drying of the grain. Then, the dust pump 111 is turned on to extract air from the inside of the dust storage box 11, so that the inside of the dust storage box 11 is negatively pressured. With the help of dust suction pipe 112 and dust suction pipe 113, the dust floating inside the processing box 1 is uniformly sucked into the inside of the dust storage box 11, preventing the dust from floating to the outside along the feed inlet 1 and the discharge outlet 3.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
