DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a grain drying and turning device comprises a base 1, a first fixed frame 2 is symmetrically fixedly installed on the top of the base 1, a fixed ring 3 is fixedly installed on the top of the first fixed frame 2, a ring groove 4 is opened in the middle of the fixed ring 3, a drying cylinder 5 is installed on the top of the two fixed rings 3, the drying cylinder 5 is inclined, a circular rotating block 6 is symmetrically fixedly installed on the outer side of the drying cylinder 5, and the circular rotating block 6 is rotatably connected with the ring groove 4, a second fixed frame 7 is symmetrically fixedly installed on both ends of the base 1, a first fixed tube 8 and a second fixed tube 9 are respectively fixedly installed on the top of the two second fixed frames 7, the ends of the first fixed tube 8 and the second fixed tube 9 are rotatably arranged with the two ends of the drying cylinder 5, a rotating rod 10 is rotatably installed in the middle of the first fixed tube 8 through a bearing, a push plate 11 for pushing and turning the grain inside the drying cylinder 5 is symmetrically and equidistantly fixedly installed in the middle of the rotating rod 10, and the rotating rod 10 rotates with the rotation of the drying cylinder 5.

[0022] like Figures 1 to 4As shown, sealing rings 12 are fixedly installed at the ends of the first fixed tube 8 and the second fixed tube 9 close to the drying cylinder 5, and the drying cylinder 5 is arranged in the middle of the sealing ring 12. A feed pipe 13 is fixedly installed at the end of the first fixed tube 8 away from the drying cylinder 5, and a screw feeder for pushing grain is installed inside the feed pipe 13. A hot air pipe 14 is fixedly installed at the end of the second fixed tube 9 away from the drying cylinder 5, and the hot air pipe 14 is connected to the hot air blower. A discharge pipe 15 is fixedly installed at the outer bottom of the second fixed tube 9.

[0023] The grain is transported to the drying drum 5 through the feed pipe 13 and the screw feeder installed inside the feed pipe 13, and the grain is dried by the hot air blower blowing hot air into the hot air pipe 14. Since the drying drum 5 is arranged at an angle, the grain will be discharged through the discharge pipe 15 when the drying drum 5 rotates.

[0024] like Figures 1 to 4 As shown, a driven gear 16 is fixedly installed on the outer side of the drying cylinder 5, a motor 17 is fixedly installed on the middle part of the base 1, a fixed rod 18 is fixedly installed on the output end of the motor 17, and a driving gear 19 is fixedly installed on the outer side of the fixed rod 18 at a position corresponding to the driven gear 16. The driving gear 19 is meshed and connected with the fixed rod 18, and the gear ratio of the driven gear 16 to the driving gear 19 is two to one.

[0025] The fixing rod 18 is driven to rotate by the motor 17 , and the driving gear 19 will also rotate synchronously. Since the driving gear 19 is meshed and connected with the fixing rod 18 , the drying cylinder 5 will rotate along the fixing ring 3 .

[0026] like Figures 1 to 4 As shown, a first sprocket 20 is fixedly mounted on one end of the fixing rod 18 away from the motor 17 , a second sprocket 21 is fixedly mounted on one end of the rotating rod 10 away from the push plate 11 , and a chain 22 is installed between the second sprocket 21 and the first sprocket 20 for transmission.

[0027] When the fixed rod 18 rotates, the first sprocket 20 also rotates. The transmission of the second sprocket 21 and the first sprocket 20 through the chain 22 will drive the rotating rod 10 to rotate, and will also drive the push plate 11 to rotate. Since the gear ratio of the driven gear 16 and the driving gear 19 is two to one, the rotation frequency of the push plate 11 is different from the rotation frequency of the drying cylinder 5. Therefore, the push plate 11 will push the grain inside the drying cylinder 5 to increase the contact area between the grain and the hot air inside the drying cylinder 5, thereby improving the drying effect of the grain.

[0028] like Figures 1 to 4 As shown, a plurality of push plates 11 are arranged in a staggered manner.

[0029] It is used to push the grain inside the drying cylinder 5 in a staggered manner.

[0030] like Figures 1 to 4 As shown, the end of the push plate 11 away from the rotating rod 10 is arranged in an arc shape and is in contact with the inner wall of the drying cylinder 5.

[0031] The grains adhering to the inner wall of the drying cylinder 5 can be pushed to prevent the grains with high moisture content from adhering to the inner wall of the drying cylinder 5 .

[0032] like Figures 1 to 4 As shown, a steam outlet pipe 23 is fixedly installed on the top of the first fixed pipe 8.

[0033] The heated water vapor can be dissipated.

[0034] The utility model provides a grain drying and turning device, and the specific working principle is as follows:

[0035] When the device is in use, the grain is transported to the drying drum 5 through the feed pipe 13 and the screw feeder installed inside the feed pipe 13, and the fixed rod 18 is driven to rotate by the motor 17, and the driving gear 19 will also rotate synchronously. Since the driving gear 19 is meshed and connected with the fixed rod 18, the drying drum 5 will rotate along the fixed ring 3. During this process, the first sprocket 20 rotates, and the transmission of the second sprocket 21 and the first sprocket 20 by the chain 22 will drive the rotating rod 10 to rotate, and will also drive the push plate 11 to rotate. Since the gear ratio of the driven gear 16 and the driving gear 19 is two to one, the rotation frequency of the push plate 11 is different from the rotation frequency of the drying drum 5. Therefore, the push plate 11 will push the grain inside the drying drum 5 to increase the contact area between the grain and the hot air inside the drying drum 5, thereby improving the drying effect of the grain.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
