After the drying is completed, the heating component 15 is turned off, the driving motor 14 continues to rotate, and the discharge component 5 is turned on. The discharge component 5 controls the discharge component 4 through the control component 3, so that the discharge component moves relative to the drying component 2 in the direction close to the discharge component 5, and then the nuts in the drying component 2 are discharged through the discharge component 5.

[0036] Furthermore, the machine body 1 includes a frame 11, a support plate 12 and a mounting plate 13, the support plate 12 and the mounting plate 13 are fixedly arranged at both ends of the frame 11, a drive motor 14 is fixedly arranged on the frame 11, a drive gear is arranged at the output end of the drive motor 14, a gear ring is arranged on the drying component 2, the drive gear is meshed with the gear ring, the heating component 15 is fixedly arranged on the support plate 12, the control component 3 and the discharging component 5 are arranged on the mounting plate 13, and a feed port 131 is fixedly arranged on the mounting plate 13.

[0037] In this embodiment, nuts are introduced into the drying component 2 through the feed port 131, and the driving motor 14 drives the drying component 2 to rotate through the driving gear and the ring gear, thereby driving the nuts to roll, so that the nuts are heated evenly and the drying effect is good.

[0038] Further, the drying assembly 2 includes a drying cylinder 21, a barrel bottom 22 and a limiting cylinder 23, the gear ring is fixedly sleeved on the drying cylinder 21, one end of the drying cylinder 21 is rotatably set on the mounting plate 13, and the other end is fixedly set with the barrel bottom 22, the barrel bottom 22 is provided with a first limiting portion 221, the limiting cylinder 23 is fixedly set on the first limiting portion 221, the limiting cylinder 23 is rotatably connected with the support plate 12 and the heating assembly 15, the discharge assembly 4 is slidably connected with the first limiting portion 221, the discharge assembly 4 is transmission-connected with the limiting cylinder 23, and the discharge assembly 4 is slidably connected with the drying cylinder 21. In this embodiment, the drying cylinder 21 is a bottomed cylindrical mechanism with one side open, one side of the opening is rotatably set on the mounting plate 13, and the other side is rotatably set on the support plate 12 through the limiting cylinder 23, the limiting cylinder 23 is a cylindrical structure, connected with the heating assembly 15, and the heating assembly 15 passes heat into the drying cylinder 21 through the limiting cylinder 23.

[0039] Furthermore, the discharge assembly 4 includes a transmission assembly 41, a sealing plate 42, a synchronization ring 43 and a push plate 44. The sealing plate 42 is rotatably set on the mounting plate 13, and the end of the limiting cylinder 23 away from the heating assembly 15 is rotationally connected to the sealing plate 42. The synchronization ring 43 is slidably sleeved on the limiting cylinder 23. A protrusion 431 is provided on the synchronization ring 43. A spiral groove 231 is provided on the limiting cylinder 23. The protrusion 431 is slidably set on the spiral groove 231. The transmission assembly 41 is slidably connected to the sealing plate 42 and the synchronization ring 43. A push plate 44 is fixedly provided on the synchronization ring 43. A cleaning ring 45 is fixedly provided on the push plate 44. The cleaning ring 45 is slidably connected to the drying cylinder 21. The transmission assembly 41 is rotatably connected to the control assembly 3, and the transmission assembly 41 is slidably connected to the first limiting portion 221. In this embodiment, the drying component 2 drives the discharging component 4 to rotate synchronously through the transmission component 41. In the initial state, the pushing plate 44 is arranged at the bottom of the drying cylinder 21. After the drying is completed, the discharging mechanism 4 is controlled by the control mechanism 3 so that the discharging mechanism 4 no longer rotates with the drying component 2.

[0040] Further, the transmission assembly 41 includes a first snap ring 411, a synchronization rod 412 and a second snap ring 413, the first snap ring 411 and the second snap ring 413 are fixedly arranged at both ends of the synchronization rod 412, a plurality of blocks are arranged in an array around the axis of the first snap ring 411, a plurality of holes are arranged on the first limit portion 221 corresponding to the blocks, the blocks are slidably arranged in the holes, the synchronization rod 412 is slidably connected with the sealing plate 42 and the synchronization ring 43, and the second snap ring 413 is rotationally connected with the control assembly 3. In this embodiment, when the nuts are dried, the blocks on the first snap ring 411 are arranged in the holes on the first limit portion 221, so that the discharge assembly 4 rotates synchronously with the drying assembly 2, and at this time, the drying assembly 2 and the discharge assembly 4 rotate synchronously.

[0041] Furthermore, the control component 3 includes a fixed block 31, a slider 32, a second limiting portion 33 and a synchronization plate 34, the fixed block 31 and the second limiting portion 33 are both fixedly arranged on the mounting plate 13, the slider 32 is slidably arranged on the fixed block 31, a synchronization block 341 is fixedly arranged on the synchronization plate 34, the synchronization block 341 is slidingly connected to the slider 32 in the vertical direction, the second retaining ring 413 is rotatably connected to the synchronization plate 34, the second retaining ring 413 is provided with a retaining block identical to the first retaining ring 411, and the second limiting portion 33 is provided with a plurality of through holes corresponding to the retaining block. In the present embodiment, when drying is completed, the sealing door 51 is opened, and the sealing door 51 is opened upward, and at the same time, the slider 32 is pushed to slide along the fixed block 31, and the slider 32 moves obliquely upward, and the synchronization plate 34 is driven by the synchronization block 341 to move in the direction away from the mounting plate 13, and the synchronization plate 3 drives the transmission assembly 41 to move toward the second limiting portion 33, so that the block on the second retaining ring 413 moves into the through hole on the second limiting portion 33, and the rotation of the transmission assembly 41 is restricted. At this time, the drying assembly 2 continues to rotate, and the limiting cylinder 23 pushes the protrusion 431 set in the spiral groove 231, thereby pushing the synchronization ring 43, the push plate 44 and the cleaning ring 45 to move in the direction close to the sealing door 51, and the nuts are discharged from the drying cylinder 21.

[0042] Further, the discharge assembly 5 includes a sealing door 51, a support rod 52 and a lock 53. The sealing door 51 is rotatably arranged on the mounting plate 13. The support rod 52 is composed of two mutually hinged connecting rods. One end of the support rod 52 is hinged to the sealing door 51, and the other end is hinged to the mounting plate 13. The lock 53 is composed of a fixed part and a movable part. The movable part is fixedly arranged on the sealing door 51, and the fixed part is fixedly arranged on the mounting plate 13. The slider 32 is located on the rotation path of the sealing door 51. In this embodiment, the sealing door 51 rotates 90° when opened, and the angle between the two connecting rods is opened from 0° to 180°. The hinged position between the connecting rods forms a dead point to prevent the sealing door 51 from closing during the discharge process. At the same time, the sealing door 51 pushes the slider 32 to move along the fixed block 31, thereby controlling the discharge assembly 4.

[0043] Furthermore, tension springs are provided between the first snap ring 411 and the first position-limiting portion 221 and between the second snap ring 413 and the synchronous plate 34. In this embodiment, since the transmission assembly 41 is in a rotating state, the second position-limiting portion 33 is always kept fixed. When the block on the first snap ring 411 is pulled out from the first position-limiting portion 221, the block on the second snap ring 413 cannot accurately correspond to the through hole on the second position-limiting portion 33. Therefore, a tension spring is provided. When the sealing door 51 drives the synchronous plate 34 to move through the slider 32, if the block on the second snap ring 413 is not aligned with the through hole on the second position-limiting portion 33, the second snap ring 413 is firstly abutted against the second position-limiting portion 33, and the synchronous plate 34 is then moved. The second retaining ring 413 slides relative to the second retaining ring 413, and the tension spring accumulates force. As the limiting cylinder 23 drives the synchronous ring 43 to continue to rotate through the protrusion 431, the block moves into the through hole, restricting the rotation of the discharge assembly 4, so that the drying assembly 2 rotates relative to the discharge assembly 4, pushing the discharge assembly 4 to push the nuts out of the drying cylinder 21; after the sealing door 51 is closed, the tension spring between the first retaining ring 411 and the first limiting portion 221 is released, so that the second retaining ring 413 is disengaged from the first limiting portion 33, and at the same time, the first retaining ring 411 enters the second limiting portion.

[0044] Furthermore, drying holes are provided between the spiral grooves 231 on the limiting cylinder 23. In this embodiment, the drying holes are provided so that the heat output by the heating assembly 15 can be more effectively passed into the drying cylinder 21, thereby improving the drying efficiency.

[0045] During specific implementation: after the nuts are passed into the drying component 2, the heating component 15 and the driving motor 14 are started to dry the nuts in the device. The heating component 15 passes the heat into the drying cylinder 21 through the limiting cylinder 23. At this time, the drying component 2 drives the discharging component 4 to rotate synchronously. After drying, the heating component 15 is turned off, the driving motor 14 continues to rotate, and the sealing door 51 is opened. The sealing door 51 pushes the slider 32 to move along the fixed block 31, and drives the synchronous plate 34 to move away from the mounting plate 13 through the synchronous block 341. The synchronous plate 3 drives the transmission component 41 to move toward the second limiting portion 33, so that the block on the second retaining ring 413 moves into the through hole on the second limiting portion 33, limiting the rotation of the transmission component 41. At this time, the drying component 2 continues to rotate, and the limiting cylinder 23 pushes the protrusion 431 set in the spiral groove 231, thereby pushing the synchronous ring 43, the pushing plate 44 and the cleaning ring 45 to move in the direction close to the sealing door 51, and the nuts are discharged from the drying cylinder 21.

[0046] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any technician familiar with the field can make many possible changes and modifications to the technical solution of the utility model by using the above-mentioned technical content without departing from the scope of the technical solution of the utility model, or modify it into an equivalent embodiment of equivalent changes. Therefore, any changes, modifications, equivalent changes and modifications made to the above embodiments based on the technology of the utility model without departing from the content of the technical solution of the utility model shall fall within the protection scope of the technical solution of the utility model.
