Detailed Embodiment

[0020] In order to enable those skilled in the art to better understand the utility model, the technical solutions of the utility model will be further described below in conjunction with the drawings and embodiments.

[0021] Example 1: As Figures 1-4 shown, a mulberry dried fruit air dryer of the present utility model includes an air drying box 1, a hot air blower 11 is installed on the side of the air drying box 1, a box door 12 is installed on the front side of the air drying box 1, a driving motor 13 is installed on the side of the air drying box 1, the air drying box 1 is symmetrically and rotatably connected with driving sprockets 14 up and down, two driving sprockets 14 are fixedly installed with a coaxial sprocket 15, and one of the coaxial sprockets 15 is in transmission connection with the driving motor 13. The air drying box 1 is installed with a first chain 16 in transmission connection with the two driving sprockets 14, the air drying box 1 is installed with a second chain 17 in transmission connection with the two coaxial sprockets 15, and a plurality of fixing rings 18 are installed between the first chain 16 and the second chain 17. A plurality of fixing rings 18 are rotatably connected with an air drying cylinder 19, the air drying cylinder 19 is detachably connected with an arc-shaped cover 20, a gear 21 is fixedly installed on one side of the air drying cylinder 19 away from the fixing ring 18, and the air drying box 1 is provided with a travel groove matching the air drying cylinder 19 and the gear 21.

[0022] When in use, first, under the drive of the driving motor 13, the arc-shaped cover 20 of the air drying cylinder 19 close to the box door 12 is turned upwards, and then the connection between the arc-shaped cover 20 and the air drying cylinder 19 is released through a threaded bolt structure. Then, the mulberry fruits to be air-dried are put into the open air drying cylinder 19. At this time, the amount of mulberry fruits is less than half of the capacity of the air drying cylinder 19. Then, the arc-shaped cover 20 is closed to connect the air drying cylinder 19. At this time, the box door 12 is closed and the driving motor 13 is started to work. Further, the driving motor 13 drives the coaxial sprocket 15 in transmission connection with it to rotate, and then drives the driving sprocket 14 to rotate. Since the coaxial sprocket 15 and the driving sprocket 14 are respectively in transmission connection with the second chain 17 and the first chain 16, when the driving motor 13 works, it will drive the first chain 16 and the second chain 17 to move synchronously, and then drive the fixing ring 18 and the air drying cylinder 19 to move along the movement tracks of the first chain 16 and the second chain 17. In this way, the hot air blown into the air drying box 1 by the hot air blower 11 can enter through the air permeable grooves of the air drying cylinder 19 to contact and air-dry the mulberry fruits, and finally be discharged from the air outlet at the upper end of the air drying box 1. At the same time, the continuous movement of the air drying cylinder 19 along the track can uniformly contact with the hot air, avoiding different air-drying effects of the mulberry fruits near the air outlet and far from the air outlet.

[0023] The present utility model can enable the air drying cylinder to move along the track driven by the first chain and the second chain, so that the mulberry fruits roll inside the air drying cylinder, and cooperate with the air entering the air drying box from the hot air blower to uniformly contact, so that the air-drying effects of all the mulberry fruits inside the air drying box are consistent.

[0024] Example 2: On the basis of Example 1, a further improvement is made. A meshing tooth 22 matching the gear 21 is fixedly installed inside the travel groove, a communication groove communicating with the hot air blower 11 is opened inside the air drying box 1, the communication groove and the travel groove are communicated through a through hole, and an inlet matching the through hole is opened on the gear 21.

[0025] When the air-drying cylinder 19 moves following the first chain 16 and the second chain 17, the air-drying cylinder 19 and the gear 21 will move inside the travel groove, and then the gear 21 will mesh with the meshing teeth 22. In this way, when the air-drying cylinder 19 moves, it can rotate automatically under the restriction of the meshing teeth 22, so that the mulberry fruits inside the air-drying cylinder 19 roll and come into contact with the hot air, improving the air-drying efficiency. At the same time, when the through-hole of the gear 21 matches the inlet, the hot air will enter the air-drying cylinder 19 from the inlet through the gear 21, and then be discharged from the ventilation port of the air-drying cylinder 19. In this way, the hot air enters the air-drying cylinder 19 intermittently and fully contacts the mulberry fruits, improving the air-drying efficiency.

[0026] The lower side of the box door 12 is hinged to the air-drying box 1, and a sliding plate 23 is slidably connected to the upper side of the box door 12. A connecting member is installed between the sliding plate 23 and the box door 12. When the air-drying box 1 is working, the box door 12 is airtight with the air-drying box 1, so as to better air-dry the mulberry fruits. When feeding is needed, the box door 12 can be opened. When discharging is needed, the box door 12 is rotated obliquely. Then, the driving motor 13 drives the air-drying cylinder 19 to move to the position of the box door 12 and makes the arc-shaped cover 20 face the box door 12. At this time, the connection between the connecting member and the sliding plate 23 is released, and in this state, the inlet is communicated with the through-hole. In this way, the wind blown out by the hot air blower can also be used to conveniently discharge the mulberry fruits. Then, the sliding plate 23 is extended into the air-drying box 1, and the sliding plate 23 is extended to the lower side of the air-drying cylinder 19 where discharging is needed. In this way, the connection of the arc-shaped cover 20 can be released, so that the mulberry fruits fall from the air-drying cylinder 19 onto the inclined sliding plate 23, and finally slide down through the sliding plate 23 and the box door 12 into the collection equipment such as a collection bucket or a collection box for collection.

[0027] The connecting member includes a threaded rod 24. The sliding plate 23 is provided with a first threaded hole 25 that is threadedly connected to the threaded rod 24. The box door 12 is provided with a number of through-holes 26 that match the first threaded hole 25. The front end of the air-drying box 1 is provided with an embedding groove that matches the box door 12, and the embedding groove is provided with a second threaded hole 27 that matches the first threaded hole 25. When the box door 12 is connected to the air-drying box 1, the threaded rod 24 passes through the through-hole 26 and is threadedly connected to the first threaded hole 25 and the second threaded hole 27. When it is necessary to open the box door 12, the threaded rod 24 is rotated to release the connection with the second threaded hole 27. When discharging is needed, the threaded rod 24 is rotated to release the connection with the first threaded hole 25, and then the sliding plate 23 is slid into the air-drying box 1. Then, the through-hole 26 that aligns with the first threaded hole 25 is selected to pass through and is threadedly connected to the first threaded hole 25 again, so as to conveniently open the arc-shaped cover 20 for discharging.

[0028] A drawer 28 is slidably connected to the lower part of the front side of the air-drying box 1. Due to the characteristics of mulberry fruits, the small particles on the fruits are likely to fall off after air-drying and with continuous rolling. Therefore, there is a situation where fruit particles are likely to fall off. So the drawer 28 can receive the mulberry particles leaking from the air-permeable slots of the air-drying cylinder 19, and at the same time, it can also separate the fallen mulberry particles from the original mulberry fruits.

[0029] The diameter of the air-drying cylinder 19 gradually increases from both sides to the center. This facilitates the feeding of materials and the discharging of mulberry fruits.

[0030] The above embodiments are only used to exemplarily illustrate the principles and effects of the present invention, rather than to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
