The plurality of baffles 33 are equidistantly arranged in an annular manner at the bottom end of the drying cylinder 9. When the toothed ring 30 rotates, the baffle 33 is driven to rotate by the arc-shaped rod 32, so that the toothed ring 30 synchronously drives the plurality of annularly distributed baffles 33 to rotate;

[0060] In order to realize the opening of the bottom end of the drying drum 9 when the baffle plate 33 rotates, the baffle plate 33 is equidistantly arranged in an annular manner at the bottom end of the drying drum 9, and the second movable shaft 34 is fixedly connected to the inside of the baffle plate 33, and a connecting plate 39 is rotatably connected to the bottom end of the second movable shaft 34.

At the same time, a second windmill blade 56 is arranged inside the air duct 40, and a third movable rod 42 is fixedly connected to the top of the second windmill blade 56, and the third movable rod 42 is rotatably connected to the inside of the top plate 41, so that the second windmill blade 56 can drive the third movable rod 42 to rotate under the action of wind force, and a reciprocating rotating unit is transmission-connected to the top of the third movable rod 42;

[0062] Among them, the reciprocating rotation unit includes a second bevel gear 43, and the second bevel gear 43 is fixedly connected to the top end of the third movable rod 42, and the third bevel gear 44 is meshedly connected to the surface of the second bevel gear 43, and the rear end face of the third bevel gear 44 is fixedly connected to a cross bar 45. In order to achieve stable installation of the cross bar 45, a vertical plate 46 is rotatably connected to the outer wall of the cross bar 45, and the vertical plate 46 is fixedly connected to the surface of the top plate 41. At the same time, an incomplete gear 47 is fixedly connected to the end of the cross bar 45 away from the third bevel gear 44, and the outer wall of the incomplete gear 47 is meshedly connected to an internal tooth plate 48, and the upper and lower inner parts of the middle of the internal tooth plate 48 are provided with gears. Groove, under the meshing action of the inner tooth plate 48 and the incomplete gear 47, the incomplete gear 47 can drive the inner tooth plate 48 to reciprocate, and considering the stability of the moving path of the inner tooth plate 48, the inner tooth plate 48 is slidably connected to the inner top wall of the warehouse body 1. Specifically, a limiting block 49 is slidably connected to the outer wall of the inner tooth plate 48, and the limiting block 49 is fixedly connected to the inner top wall of the warehouse body 1. By sliding the inner tooth plate 48 on the inner wall of the limiting block 49, the inner tooth plate 48 can slide stably on the inner top wall of the warehouse body 1, which is convenient for the inner tooth plate 48 to achieve precise movement through the rotation of the incomplete gear 47, and a diverting material guide unit is connected to the inner tooth plate 48.

[0063] Furthermore, the material guide unit includes three groups of side plates 54 arranged at intervals outside the two feed ports 4, each group of side plates 54 is two symmetrically arranged side plates 54, and the side plates 54 are fixedly connected to the top of the drying cylinder 9, and a through hole for accommodating the movement of the guide belt 53 is opened on the top of the drying cylinder 9. The inside of each group of side plates 54 is rotatably connected to the rotating cylinder 52, and the surface of the rotating cylinder 52 is fitted with the guide belt 53, and the two ends of the guide belt 53 are respectively fixedly connected to the rotating cylinder 52 on both sides, and the bottom end of the feed port 4 is rotatably connected to the guide cylinder 55, and the guide cylinder 55 The bottom end of the drying drum 9 is connected with a guide belt 53, and the guide cylinder 55 is distributed in parallel with the rotating drum 52. By arranging the guide cylinder 55 at the bottom of the feeding port 4, the guide belt 53 can be reciprocated to receive and guide the materials at the bottom of the feeding port 4, thereby ensuring the movement effect of the guide belt 53 at the bottom of the feeding port 4. Moreover, by arranging the guide belt 53 in an oblique "human" shape on both sides, the guide belt 53 can be divided and guided at the bottom of the feeding port 4, so that the grains can be lifted inside the drying drum 9. In addition, in order to realize the driving of the rotating drum 52, two guide cylinders on the outer side of the feeding port 4 are provided. One end of each rotating drum 52 is fixedly connected to a side rod 51, and a gear plate 50 is fixedly installed at one end of the side rod 51 away from the rotating drum 52. The two gear plates 50 are respectively meshed and connected to the bottom ends of the two sides of the inner tooth plate 48. By fixing the side rod 51 on one side of the two rotating drums 52, under the meshing action of the gear plate 50 and the inner tooth plate 48, the inner tooth plate 48 can synchronously drive the gear plates 50 on both sides to rotate in the same direction, so that the rotating drums 52 on both sides drive the guide belt 53 fixedly connected on the surface to move at the bottom of the feed port 4, so that the guide belt 53 can move back and forth in the feed port 4. The bottom of the feed port 4 receives the material and guides the material to both sides. In order to achieve the guide belt 53's guide, the guide belt 53 and the three rotating drums 52 are arranged in a "W" shape, and the guide belt 53 is located at the bottom of the feed port 4. The three rotating drums 52 drive the guide belt 53 to reciprocate at the bottom of the feed port 4. At the same time, the surface of the guide belt 53 is arranged in a "human" shape structure, so that the guide belt 53 guides the grains on the surface to both sides, which is convenient for the grains to be fully scattered and lifted at the top of the drying drum 9, which is beneficial to improving the subsequent drying effect of the grains.

[0064] The working principle of the present invention is as follows: when in use, the grains enter the guide pipe 3 through the elevator 2, and then enter the drying cylinder 9 through the feed port 4. Under the action of the spiral plate 10 fixedly connected to the inner wall of the drying cylinder 9, the grains slide inside the drying cylinder 9 through the spiral plate 10, thereby increasing the residence time of the grains inside the drying cylinder 9. At the same time, by connecting the dryer to one side of the air inlet 5, the hot air enters the interior of the silo 1 through the air inlet 5, which is convenient for heating the outer wall of the drying cylinder 9 and achieving the drying of the grains inside the drying cylinder 9. Moreover, by arranging the air outlet at the top of the silo 1, the return air of the dryer is stable, which is convenient for the hot air duct to circulate inside the silo 1, thereby ensuring the internal humidity of the silo 1. When the hot air enters the interior of the silo 1, the hot air is discharged through the silo 1. An air guide column 12 and an air guide duct 40 are arranged on the surface of the fixed plate 11. Under the action of the arcs symmetrically arranged on the outer side of the drying cylinder 9, the hot air can move in the direction of the air guide duct 40 through the air guide column 12, and finally return air through the air outlet on the top. At the same time, a first movable rod 13 is rotatably arranged inside the air guide column 12. Under the action of a first windmill blade 14 fixedly connected to one end of the first movable rod 13, the hot air duct blows the first windmill blade 14 to rotate, thereby realizing the rotation of the first movable rod 13 inside the air guide column 12. The opening assembly is pulled through the transmission connection of the first movable rod 13, so that the first movable rod 13 drives the second movable rod 18 to rotate through the first synchronous belt 16. Under the action of the incomplete bevel gear 19 connected to the first end, the incomplete bevel gear 19 drives the first bevel gear 20 to rotate intermittently. Through the intermittent rotation of the first bevel gear 20 and the turntable 25, the turntable 25 drives the rack 29 to pull through the pull rod 27. The toothed groove ring 30 is meshed with the outer wall of the rack 29, so that the toothed groove ring 30 rotates on the surface of the connecting plate 39. By connecting multiple arc rods 32 in an annular manner on the surface of the toothed groove ring 30, the multiple arc rods 32 synchronously drive the baffle 33 to move, so that one end of the baffle 33 is pulled by the arc rod 32, and the baffle 33 is rotated on the surface of the connecting plate 39 through the second movable shaft 34, so that the multiple baffles 33 are synchronously opened at the bottom of the drying cylinder 9. The third movable rod 42 is connected to the bottom of the drying drum 9 by rotation, and the second windmill blade 56 is fixedly connected to the bottom of the third movable rod 42. The hot wind flowing upwards drives the second windmill blade 56 to rotate, thereby rotating the third movable rod 42. The second bevel gear 43 is fixedly connected to the surface of the third movable rod 42. Under the action of the second bevel gear 43 and the third bevel gear 44, the third bevel gear 44 drives the incomplete gear 47 to rotate through the cross bar 45. Under the action of the upper and lower meshing inner tooth plates 48 of the incomplete gear 47,The inner tooth plate 48 is reciprocated, so that the inner tooth plate 48 can synchronously drive the gear plates 50 on both sides to rotate in the same direction, so that the rotating drums 52 on both sides drive the guide belts 53 fixedly connected on the surface to move at the bottom of the feed port 4, so that the guide belts 53 pass through the material receiving at the bottom of the feed port 4 through reciprocating movement and guide the material to both sides. By setting the surface of the guide belts 53 in a "human" shape, the guide belts 53 guide the grains on the surface to both sides, so that the grains can be fully scattered and lifted at the top of the drying drum 9, and the grains can be fully dried inside the drying drum 9, thus completing the working principle of the auger-free static dryer.

[0065] In summary, in the present invention, by arranging air ducts 40 and air guide columns 12 on both sides of the drying cylinder 9, the hot air is used to heat the drying cylinder 9 in a circular manner inside the bin body 1. The hot air flows around the drying cylinder 9 to achieve the flow of heat outside the drying cylinder 9, which is convenient for efficiently and evenly drying the grains. Compared with the existing single bottom drying, the heat conduction area is increased, and the arrangement of the first windmill blades 14 and the second windmill blades 56 enables the pulling and opening bin assembly and the diverting material guide unit to stably load and discharge the inside of the drying cylinder 9 through the flow of hot air, thereby achieving efficient drying of the grains inside the bin body 1, and solving the technical problem that the current augerless static dryer has a single air duct flow direction and cannot evenly dry the grains in bulk at different positions inside the augerless static dryer.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
