[0027] The working principle and use process of the utility model are as follows: during actual use of the drying device, first, the base 1 is stably placed in a working area, then the air conveying pipe 7 is connected with an external air pump, the air pump is started, air is conveyed into the air box 5 through the air conveying pipe 7, the impeller 6 is forced to rotate under the impact of the airflow, the rotation of the impeller 6 further extracts air at the air conveying pipe 7, and the airflow is pressed into the heat conduction cavity 9 through the air hole 8, and the rotation of the impeller 6 also drives the inclined plate 4 to deflect synchronously in the drying cylinder 2 at the same time.
[0028] At this time, the sealing cover 141 on the hopper 14 at the top of the drying cylinder 2 is rotated and removed, and the grain is fed into the drying cylinder 2 through the hopper 14 at the top of the drying cylinder 2, and then the grain will fall onto each inclined plate 4 under the action of gravity during the rotation of each inclined plate 4, and will exert a force of gravity on the inclined plate 4, giving the inclined plate 4 a deflection force, which will form a resultant force with the air flow impact force on the impeller 6, forcing the rotating inclined plate 4, the drum 3 and the impeller 6 to rotate at a faster speed, and the faster rotation of the impeller 6 will further draw air at the air inlet pipe 7, making the air flow faster, thereby forming a positive feedback, with the force of gravity on the inclined plate 4 as the main deflection force, forcing the grain to roll with the inclined plate 4 inside the drying cylinder 2;
[0029] According to the actual situation, after filling the drying cylinder 2 with an appropriate amount of grain, the previously removed sealing cover 141 is installed and reset, and the heating wire 10 is powered on. At this time, the air flowing into the heat conduction cavity 9 will be heated by the heating wire 10 into a hot air flow, which will then be uniformly blown to the grain inside the drying cylinder 2 under the guidance of the air guide seat 11, and will be forced to dry quickly under the blowing of the hot air flow, and then the hot air flow will pass through the sieve plate 12 into the drum 3, and then flow into the air box 17 through the conduit 13, forcing the rotating wheel 18 to rotate under the impact of the air flow, and causing the spiral conveying roller 16 to rotate synchronously inside the feeding barrel 15 under the drive of the rotating wheel 18, and then the air flow will flow out through the exhaust pipe 22 and be discharged into the air after being filtered by the activated carbon and filter sponge inside the filter box 23;
[0030] During the rolling and shifting of the grain with the inclined plate 4 inside the drying cylinder 2, when it is positioned directly above the hopper 14 at the bottom of the drying cylinder 2, it will fall into the hopper 14 at the bottom of the drying cylinder 2 and roll into the bottom of the feeding barrel 15 along with the hopper 14 at the bottom of the drying cylinder 2, and at this time the rotating spiral conveying roller 16 will send it to the hopper 14 at the top of the drying cylinder 2 along the feeding barrel 15, and then it will be evenly scattered onto each inclined plate 4 again, thereby promoting the circulation and rolling of the grain, which can further promote the uniform heating of the grain and improve the drying rate of the grain;
[0031] During the filling of the grain, it is important to note that the less grain filled, the more hot air flow per unit time that the grain will share during the rolling and flowing process, and the faster the drying rate, but the loading and unloading frequency needs to be increased, and the loading and unloading frequency and drying rate can be comprehensively controlled according to actual needs. During the rolling and flowing of the grain, small particles of impurities carried by the grain will pass through the sieve plate 12 and fall into the impurity drawer 20 inside the drum 3 for collection. After the drying is completed, an external receiving device is placed directly below the hopper 14 at the bottom of the drying cylinder 2, the sealing cover 141 of the hopper 14 is removed, and the grain that has completed drying can be transported.
[0032] Finally, it should be noted that: the above is only the preferred examples of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
