[0055] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0056] Example 1: Refer toFigures 1 - 6 As shown in the figure, a bagged bamboo shoot dryer includes a box body 1 with an opening at the front end, and a door panel 30 is rotatably connected to the front end of the box body 1.

[0057] A partition 2 is fixed inside the box body 1, and the partition 2 divides the box body 1 into a heating chamber and a drying chamber. A heater 3 is fixed in the heating chamber.

[0058] A hot air circulation component is arranged on the box body 1, and the hot air circulation component can make the air inside the box body 1 circulate between the heating chamber and the drying chamber.

[0059] The hot air circulation component includes an air inlet pipe 4 fixed on the box body 1 and communicating with the heating chamber. An air inlet valve 5 is installed on the air inlet pipe 4. An upper hole is opened in the upper part of the partition 2, and an upper fan 6 is installed in the upper hole. The upper fan 6 can draw the air in the heating chamber into the drying chamber. A lower hole is opened in the lower part of the partition 2, and a lower fan 7 is installed in the lower hole. The lower fan 7 can draw the air in the drying chamber into the heating chamber. A humidity sensor 10 is fixed in the drying chamber. An exhaust pipe 8 is fixed on the box body 1 and communicates with the drying chamber. An exhaust valve 9 is installed on the exhaust pipe 8. A controller is fixed on the box body 1. The controller, the upper fan 6, the lower fan 7, the humidity sensor 10, the air inlet valve 5 and the exhaust valve 9 are electrically connected.

[0060] When drying bamboo shoots, the heater 3 generates heat, and the upper fan 6 and the lower fan 7 are started, and the air circulates between the heating chamber and the drying chamber. The circulating air contacts the heater 3 and then the temperature rises, and the high-temperature air can dry the bamboo shoots when it contacts them.

[0061] The humidity sensor 10 monitors the humidity in the drying chamber in real time. A humidity threshold is set in the controller. When the humidity value detected by the humidity sensor 10 in the drying box is greater than the humidity threshold, the controller opens the air inlet valve 5 and the exhaust valve 9, and at the same time the controller closes the lower fan 7, and the upper fan 6 remains in the starting state. At this time, the air outside the box body 1 passes through the air inlet pipe 4, the heating chamber, the upper fan 6, the drying chamber and the exhaust pipe 8 and is discharged to the outside of the box body 1, thereby being able to reduce the humidity inside the box body 1.

[0062] When the humidity value detected by the humidity sensor 10 in the drying box is less than the humidity threshold, the controller closes the air inlet valve 5 and the exhaust valve 9, and at the same time the controller opens the lower fan 7, and the air continues to circulate between the heating chamber and the drying chamber.

[0063] There is a drying rack inside the drying box. The drying rack includes a rotating pipe 13, and a long slot 16 is opened on the rotating pipe 13. The length direction of the long slot 16 is parallel to the axial direction of the rotating pipe 13. At the upper end of the rotating pipe 13, an upper plate 23 is fixed. A plurality of support frames are slidably sleeved on the outer side of the rotating pipe 13 below the upper plate 23. Adjacent two support frames are connected by a plurality of pull ropes 27, and the upper plate 23 and the support frame below it are connected by a plurality of pull ropes 27.

[0064] The pull ropes 27 can keep a certain distance between adjacent two support frames and between the upper plate 23 and its adjacent support frame. When drying the bamboo shoots in the support frame, it is convenient for the water in the bamboo shoots to be discharged into the drying cavity.

[0065] The support frame includes a sliding sleeve 26 slidably sleeved on the rotating pipe 13. A convex block is fixed on the inner edge of the sliding sleeve 26, and the convex block is slidably clamped in the long slot 16. An outer ring 24 is concentrically arranged on the outer side of the sliding sleeve 26, and the lower end of the outer ring 24 is fixedly connected with the sliding sleeve 26 through a net plate 25. The support frame can only move along the axial direction of the rotating pipe 13. When the rotating pipe 13 rotates, the support frame can rotate accordingly.

[0066] During the drying process of the bamboo shoots, the rotating pipe 13 can drive the support frame to rotate, and the support frame drives the bamboo shoots inside it to rotate, so as to make the bamboo shoots heat evenly.

[0067] A slot 14 is opened at the lower end of the rotating pipe 13, and a plug 12 is inserted into the slot 14. The plug 12 is rotatably connected with the lower end of the rotating pipe 13. Specifically, the plug 12 is rotatably connected with the lower end of the rotating pipe 13 through a pin shaft. The pin shaft is perpendicular to the rotating pipe 13 and perpendicular to the plug 12. A motor 11 is fixed at the lower end of the box body 1, and the upper end of the output shaft of the motor 11 is fixedly connected with the plug 12.

[0068] After the motor 11 stops rotating, the rotating pipe can be manually rotated to make the pin shaft in a horizontal state. Opening the door panel 30 can make the rotating pipe 13 drive the upper plate 23 and the support frame on it to rotate out to the outside of the box body 1.

[0069] An activity block 18 is slidably arranged in the rotating pipe 13 below the lower side of the lowermost support frame, and at least one end of the activity block 18 penetrates through the long slot 16. A driving component is arranged in the rotating pipe 13. The driving component is connected with the activity block 18. When the driving component drives the activity block 18 to move upward, the activity block 18 can push a plurality of support frames to move upward.

[0070] The driving component includes a screw rod 17 rotatably connected in the rotating pipe 13. The screw rod 17 penetrates through the activity block 18, and the screw rod 17 is threadedly connected with the activity block 18. The upper end of the screw rod 17 extends above the rotating pipe 13, and a spline shaft 19 is concentrically fixed at the upper end of the screw rod 17.

[0071] When the screw rod 17 rotates relative to the rotating pipe 13, the movable block 18 can move upward and drive multiple support frames to move upward. After the upper plate 23 contacts the support frames below it, adjacent support frames come into contact. Then, the rotating pipe 13 rotates around the pin shaft, causing the support frames to rotate out of the box body 1. During the process of the support frames rotating out of the box body 1, the dried bamboo shoots in the support frames will not fall off.

[0072] A connecting component is arranged in the box body 1 above the rotating pipe 13. After the connecting component is connected to the driving component, the driving component can rotate relative to the rotating pipe 13.

[0073] The connecting component includes an upper telescopic rod 21 fixed to the lower end of the top plate of the box body 1. The upper telescopic rod 21 is arranged vertically and is concentric with the screw rod 17. A spline sleeve 20 is concentrically fixed to the lower end of the upper telescopic rod 21. A vertical connecting rod 22 is fixed to one side of the spline sleeve 20. The connecting rod 22 is slidably connected to the top plate of the box body 1.

[0074] Drive the upper telescopic rod 21 to make the spline sleeve 20 and the connecting rod 22 move downward. When the spline sleeve 20 is sleeved outside the spline shaft 19, the screw rod 17 cannot continue to rotate with the rotating pipe 13, but when the rotating pipe 13 rotates, the movable block 18 remains rotating with the rotating pipe 13. Therefore, when the rotating pipe 13 rotates, the movable block 18 can move upward along the axial direction of the rotating pipe 13. After the movable block 18 moves upward, it can push multiple support frames upward.

[0075] A rotating sleeve 15 is rotatably connected to the rotating pipe 13 below the movable block 18. One end of the rotating sleeve 15 is rotatably connected to one end of the lower telescopic rod 29, and the other end of the lower telescopic rod 29 is rotatably connected to the box body 1.

[0076] Start the lower telescopic rod 29, and the rotating pipe 13, the support pipe, and the upper plate 23 can rotate around the pin shaft, and then the support frames can be rotated out to the outside of the box body 1.

[0077] During operation, place the bamboo shoots on multiple mesh plates 25, and then start the heater 3, the upper blower 6, and the lower blower 7 to dry the bamboo shoots on the mesh plates 25. During the drying process of the bamboo shoots, start the motor 11. The output shaft of the motor 11 drives the rotating pipe 13, the support frames, and the upper plate 23 to rotate through the insert block 12, so that the bamboo shoots can be heated evenly.

[0078] After the bamboo shoots are dried, turn off the motor 11 and open the door panel 30. Then start the upper telescopic rod 21 so that the spline sleeve 20 is sleeved on the spline shaft 19. At this time, the screw 17 cannot rotate. Start the motor 11, and the motor 11 drives the rotating pipe 13, the support frame and the upper plate 23 to rotate. During the rotation of the rotating pipe 13, the movable block 18 moves upward. When the movable block 18 moves upward, it can drive multiple support frames to move upward. After the upper plate 23 contacts the support frame below it, two adjacent support frames contact each other. Then turn off the motor 11. After the motor 11 is turned off, the rotating pipe 13 stops rotating, and the rotating pipe 13 can be manually rotated so that the pin shaft is in a horizontal state. When the rotating pipe 13 rotates around the pin shaft, the support frame can be rotated out from the open end of the box body 1 to the outside of the box body 1.

[0079] Then start the lower telescopic rod 29 so that the lower telescopic rod 29 extends. During the extension of the lower telescopic rod 29, the upper end of the rotating pipe 13 rotates around the pin shaft towards the outside of the box body 1 until the support frame is rotated out to the outside of the box body 1. After the support frame is located outside the box body 1, since the upper plate 23 contacts the support frame below it and two adjacent support frames contact each other, the dried bamboo shoots in the support frame will not fall out.

[0080] Place the tray 31 under multiple support frames, and manually rotate the screw 17 to make the movable block 18 move away from the support frame. After the movable block 18 moves away from the support frame, the support frames move away from each other. After the support frames move away from each other, the dried bamboo shoots in the support frame will fall into the tray 31, so it is convenient to quickly discharge the dried bamboo shoots in multiple support frames.

[0081] In this embodiment, in order to quickly discharge the dried bamboo shoots, the rotation angle of the upper end of the rotating pipe 13 towards the outside of the box body 1 is 90 degrees. At the same time, the support frame is close to the tray 31, which can prevent the dried bamboo shoots from falling from a high place and breaking after impact.

[0082] Embodiment 2: On the basis of Embodiment 1, referring to Figure 2 、 Figure 3 and Figure 5 as shown, springs 28 are fixed to the upper ends of the sliding sleeves 26, and the springs 28 are sleeved outside the rotating pipe 13.

[0083] In this embodiment, by setting the springs 28, when the movable block 18 drives the support frames to approach each other, the springs 28 can be compressed and store energy. When the support frame is rotated out of the box body 1 and the movable block 18 moves away from the support frame, under the elastic force of the springs 28, the support frames can automatically move away from each other, which is convenient for discharging the dried bamboo shoots in the support frames.

[0084] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
