[0018] 1. This utility model incorporates a sieve. The motor drives the second transmission rod to rotate, which in turn drives the tilting frame to rotate. The tilting frame then drives the connecting rod to rotate, which in turn drives the second helical gear to rotate. The second helical gear then drives the third helical gear to rotate, which in turn drives the helical gear and the third transmission rod to rotate. The third transmission rod then drives the large gear to rotate, which in turn drives the small gear to rotate at high speed. The small gear then drives the transmission rod to rotate, which in turn drives the cam to rotate at high speed. During this rotation, the cam intermittently pushes the displacement frame, thus ensuring thorough sieving of the flour before drying. This process removes large impurities from the flour while loosening clumps of wheat, preventing any impact on the quality of the finished flour after drying.

[0019] 2. This utility model incorporates a turning frame. During operation, a helical gear drives a sleeve rod to rotate, which in turn drives a second turning frame to rotate. The second turning frame rotates in the opposite direction to the first turning frame. As they rotate, the second turning frame and the first turning frame work together to continuously turn the flour inside the drying chamber, ensuring that the flour is dried more thoroughly and completely. This allows for continuous turning of a large quantity of wheat undergoing drying in the drying chamber, preventing some flour from not being completely dried due to limited heating areas.

[0035] One specific application of this embodiment is:

[0036] When the equipment is needed, the wheat to be dried can be poured directly into the feed hopper 202. The wheat will fall into the drying chamber 1 through several holes on the surface of the sieve 205. During this process, the sieve 205 will remove large impurities from the wheat. The motor 302 and heating rod 101 are then started. The motor 302 drives the transmission rod 303 to rotate, which in turn drives the tilting frame 304 to rotate. The tilting frame 304 then drives the connecting rod 305 to rotate. This will drive helical gear 2 (309) to rotate, which in turn will drive helical gear 3 (312) to rotate. Helical gear 3 (312) will then drive helical gear 308 and transmission rod 3 (311) to rotate. Transmission rod 3 (311) will then drive large gear 313 to rotate, which in turn will drive small gear 210 to rotate at high speed. Small gear 210 will then drive transmission rod 209 to rotate, which will then drive cam 211 to rotate at high speed. Cam 211 will intermittently push displacement frame 204 during its rotation, thus displacing... The frame 204 intermittently drives the screen 205 to move and squeezes several springs 208. When the cam 211 rotates to a certain extent, the springs 208 will drive the displacement frame 204 to reset due to their own physical properties. During this period, the displacement frame 204 will drive the screen 205 to move back and forth to speed up the sieving of wheat on its surface and break up the clumps of wheat. Several heating rods 101 will dry and heat the wheat in the drying chamber 1. During this period, the helical gear 308 will drive the sleeve rod 306 to rotate, and the sleeve rod 306 will drive the second turning frame 307 to rotate. The second turning frame 307 will rotate in the opposite direction to the turning frame 304. The second turning frame 307 and the turning frame 304 will cooperate with each other to continuously turn the wheat in the drying chamber 1 while rotating, so that the wheat is indirectly dried more fully and thoroughly. If it is necessary to remove the dried wheat in the drying chamber 1, the baffle plate 316 can be pulled out from the slot 315, and the wheat can flow directly out of the equipment through the feed pipe 314.
