[0029] like Figure 1-Figure 5As shown together, this embodiment provides a tower-type rice drying device, including a drying tower 1 and a base 2 fixedly arranged on the outer wall of the drying tower 1, a discharge box 3 is provided at the lower end of the drying tower 1, a feed port 4 is provided on one side of the upper end face of the drying tower 1, a transport component 5 is provided on one side of the outer wall of the drying tower 1, and the transport component 5 includes a transport tower 501 fixedly arranged at the lower end of the discharge box 3, the transport tower 501 is located at the lower end of the discharge box 3 and is provided with a discharge port 502, a discharge port 503 is provided on the outer wall of the lower end of the transport tower 501, and the transport tower 501 is close to the discharge box 3. The outer wall at one end of the discharge port 502 is fixedly connected to a first motor 506, and the output end of the first motor 506 is connected to a first auger 507. The upper end of the transport tower 501 is fixedly connected to a second motor 508, and the output end of the second motor 508 is connected to a second auger 509. The outer wall of the upper end of the transport tower 501 close to the second motor 508 is connected to a guide bin 510. One end of the outer wall of the drying tower 1 is fixedly connected to a hot air blower 7, and the air outlet end of the hot air blower 7 is connected to a diversion pipe 8, and the outer wall of the diversion pipe 8 is connected to several groups of air ducts 9.
[0030] The inner cavity of the discharge box 3 is opened in the shape of a quadrangular pyramid that tilts downward from top to bottom. The lower end opening of the discharge box 3 and the discharge port 502 are located on the same vertical plane and are connected to each other.
[0031] The transport assembly 5 further includes an adjustment groove 504 provided on the inner wall of the lower end of the transport tower 501 , and a sealing plate 505 cooperating with the discharge port 503 is movably inserted into the inner wall of the adjustment groove 504 .
[0032] The first auger 507 and the second auger 509 are perpendicular to each other, and the transport tower 501 is set to be L-shaped. The end of the first auger 507 away from the first motor 506 is located at the corner of the inner cavity of the transport tower 501, and the lower end of the second auger 509 is located at the corner of the inner cavity of the transport tower 501. The guide bin 510 is inclined from top to bottom toward the feed port 4.
[0033] One end of the air duct 9 away from the diversion pipe 8 passes through the outer wall of the drying tower 1. The other end of the air duct 9 away from the diversion pipe 8 is fixedly connected to a blocking block 10. The inner wall of the blocking block 10 is penetrated by a plurality of groups of air outlet holes.
[0034] The sealing plate 505 is pulled out from the regulating tank 504, and the sealing plate 505 seals the discharge port 503. Then, the rice to be dried is poured into the drying tower 1 from the feed port 4, and the hot air blower 7 is started at the same time. The hot air blower 7 blows the hot air from the air duct 9 into the drying tower 1 through the diverter pipe 8 in sequence to dry the rice in the drying tower 1. Then, the rice falls into the transport tower 501 through the lower end opening of the discharge box 3. The first motor 506 and the second motor 508 are started to drive the first auger 507 and the second auger 509 to rotate respectively. The rice that falls into the inner cavity of the transport tower 501 is transported to the end away from the first motor 506 along the first auger 507, and then is transported to the transport tower 50 by the second auger 509. 1 is discharged from the guide bin 510 at the upper end, and falls into the drying tower 1 through the feed port 4 again for secondary drying, so that the hot air discharged through the air duct 9 is dried repeatedly until the rice is completely dried, thereby preventing the rice from accumulating in the drying tower 1 and causing uneven drying. The setting of the blocking block 10 can prevent the rice in the drying tower 1 from entering the air duct 9. The aperture of the ventilation hole of the blocking block 10 is smaller than the size of the rice. After multiple dryings, the moisture of the rice is dried, and the sealing plate 505 can be slid and retracted into the regulating tank 504. The first auger 507 and the second auger 509 are continued to operate until the rice in the drying tower 1 is completely discharged from the discharge port 503, and the drying of the rice is completed.
[0035] like Figure 1-Figure 5 As shown, the inner wall of the drying tower 1 is provided with three groups of mutually symmetrical slow flow components 6 from top to bottom.
[0036] The slow flow assembly 6 includes a slow flow plate 61 rotatably arranged on the inner wall of the drying tower 1. The slow flow plate 61 is arranged in a stepped shape from top to bottom. The slow flow plate 61 tilts downward from top to bottom. The lower end of the slow flow plate 61 is hinged with an adjustment frame 62.
[0037] The drying tower 1 is located at the lower end of the slow flow plate 61 and is fixedly connected to a slide rod 63. The outer wall of the slide rod 63 is movably sleeved with a slide sleeve 64. The outer wall of the slide sleeve 64 is hinged to the lower end of the adjustment frame 62. The outer wall of the slide rod 63 is sleeved with a spring 65. The upper and lower ends of the spring 65 are fixedly connected to the slide sleeve 64 and the slide rod 63 respectively.
[0038] When the rice falls to the upper end of the slow flow plate 61 through the feed port 4, the slow flow plate 61 is affected by the gravity of the rice and rotates downward along the inner wall of the drying tower 1 by a certain angle. At the same time, the adjusting frame 62 is driven to drive the sliding sleeve 64 to compress the spring 65. The reverse elastic force of the spring 65 provides a buffering force to the slow flow plate 61, so that the speed at which the rice falls along the slow flow plate 61 is reduced. The rice slides from the end of the slow flow plate 61 and falls to the slow flow plate 61 below in the air, so that the rice can stay in the drying tower 1 for a longer time. In the process of falling between the slow flow plates 61 and the slow flow plates 61, the rice is evenly scattered from top to bottom, which can make the rice heated more evenly to a certain extent.
[0039] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
