[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] Refer to the attached Figure 1-8A fruit drying oven includes a box body 1. A ceramic heater is provided in the box body 1 to precisely control the temperature and keep the original color of fruits and vegetables unchanged. The ceramic heater is not specifically shown in the figure. A loading tray 2 is provided in the box body 1. A flip shovel 3 is provided on the top of the material-carrying portion thereof. When the fruit is dried, the flip shovel 3 scoops up the fruit in the material-carrying portion of the loading tray 2 and flips it, so as to improve the drying effect and quality of both sides of the fruit. One side of the top of the flip shovel 3 is provided in the shape of an inclined thin sheet. The flip shovel 3 can scoop up the fruit in the material-carrying portion of the loading tray 2 to facilitate the work of the flip shovel 3.

[0032] The outer edge of the loading tray 2 is provided with an upwardly protruding outer edge 21, which can prevent the fruit from sliding off the edge of the loading tray 2 during the flipping process. The center of the loading tray 2 is provided with an upwardly protruding inner edge 22 to block the flipped fruit. The inner edge 22 is sleeved on the outer wall of the rotating ring 4 to position and stabilize the rotating ring 4. A number of ventilation holes 23 are provided in the material-carrying part of the loading tray 2. These ventilation holes 23 allow hot air to flow freely above and below the loading tray 2, ensuring that the fruit can be heated evenly and improving the drying effect.

[0033] The center of the loading tray 2 is provided with a rotating ring 4, and the top of the flip shovel blade 3 is connected to a shovel arm 5 through an upwardly protruding boss. One end of the shovel arm 5 is inserted into the rotating ring 4 to realize that the flip shovel blade 3 follows the rotating ring 4 to rotate around the axis of the loading tray 2. The outer wall of the shovel arm 5 is provided with a driven gear 6, and the outer wall of the driven gear 6 is meshed with a driving gear 7 to realize the flipping shovel blade 3 to flip around the axis of the shovel arm 5, and the rotating ring 4 is controlled to intermittently rotate a certain angle. During this process, the rotating ring 4 can drive the shovel arm 5 to rotate around the axis of the loading tray 2, further enabling the flip shovel blade 3 to intermittently scoop up the fruit in an arc area on the loading tray 2, and then drive the driven gear 6 to rotate through the driving gear 7, further enabling the shovel arm 5 to rotate around its own axis. At this time, the flip shovel blade 3 flips the fruit thereon, thereby ensuring that all sides of the fruit can be heated evenly, avoiding the occurrence of local drying transition or insufficient drying, and effectively improving the drying efficiency and quality.

[0034] In this embodiment, the bottom of the rotating ring 4 extends downward to the bottom of the loading plate 2, and a plurality of pairs of teeth 41 are equidistantly provided on the outer wall of the bottom of the rotating ring 4. A plurality of positioning posts 42 are equidistantly provided on the bottom of the rotating ring 4, which are relatively staggered with the teeth 41. The teeth 41 and the positioning posts 42 are arranged so as to realize the intermittent rotation of the rotating ring 4, thereby controlling the rotation rhythm of the flipping shovel 3, so as to meet the flipping requirements of the fruit during the drying process. A driving disk 81 is provided in the box body 1, and a pair of driving grooves 82 are provided on the outer edge of the driving disk 81. A driving tooth structure that matches the teeth 41 is formed between the two driving grooves 82. A driving plate 83 that matches the positioning posts 42 is provided on one side of the driving disk 81 to realize intermittent meshing connection between the teeth 41 and the driving tooth structure. During the continuous rotation, the driving plate 83 will intermittently contact the positioning column 42 and push the rotating ring 4 to rotate around its own axis, further causing the driving tooth structure on the driving disk 81 to form a meshing connection with the teeth 41 on the outer wall of the rotating ring 4. At this time, the rotating ring 4 will intermittently rotate a certain angle. Driven by the shovel arm 5, the flip shovel blade 3 will also intermittently rotate a certain angle. At this time, the flip shovel blade 3 can intermittently scoop up fruits within a certain sector-shaped range. During the continuous rotation of the driving disk 81, the flip shovel blade 3 can intermittently scoop up all the fruits in the material carrying portion of the loading tray 2. After scooping up the fruits, the flip shovel blade 3 is controlled to flip, thereby ensuring that all surfaces of the fruits can be evenly and fully exposed to the hot air, thereby ensuring the uniformity and adequacy of the drying process.

[0035] In this embodiment, an extension column 71 is provided at the bottom of the driving gear 7, and the extension column 71 passes downward through the inner cavity of the rotating ring 4 and extends to the bottom of the rotating ring 4. An external gear 72 is provided on the outer wall of the bottom of the extension column 71, and a convex ring 84 is provided in the box body 1. The outer wall of the convex ring 84 is provided with a plurality of equidistant tooth grooves 85, and a plurality of arc-shaped driving tooth areas that cooperate with the external gear 72 are formed between the plurality of equidistant tooth grooves 85, so that the convex ring 84 drives the extension column 71 to rotate intermittently. When the convex ring 84 rotates, the arc-shaped driving tooth area will intermittently form a meshing connection with the external gear 72. At this time, the driving gear 7 can intermittently rotate a certain angle, further allowing the driven gear 6 to drive the shovel arm 5 to flip a certain angle. At this time, the fruit on the flip shovel blade 3 can be flipped out. This design enables the flip shovel blade 3 not only to rotate with the rotating ring 4, but also to realize its own flipping action, thereby improving the flexibility of fruit flipping and helping to improve the drying quality.

[0036] In this embodiment, the side of the convex ring 84 facing away from the tooth groove 85 is fixedly connected to the driving disk 81. At this time, the gear 7 and the rotating ring 4 can be driven by a driving structure, which reduces the manufacturing cost of the equipment. The radius of the convex ring 84 is smaller than the distance between the driving plate 83 and the axis of the driving disk 81. The tooth groove 85 and the driving groove 82 are relatively staggered to achieve asynchronous rotation of the driving gear 7 and the rotating ring 4. During the rotation of the driving disk 81, the driving tooth structure in the driving groove 82 will first engage with the teeth 41 on the outer wall of the rotating ring 4, and make the rotating ring 4 rotate a certain angle. At this time, the flip shovel 3 will first rotate around the axis of the rotating ring 4, and move the water in the arc area on the loading plate 2. The fruit is scooped up, and then the arc-shaped driving tooth area in the tooth groove 85 drives the driving gear 7 to rotate through the outer gear 72, and further causes the flip shovel blade 3 to rotate around the axis of the shovel arm 5. At this time, the flip shovel blade 3 flips over to turn the fruit on it, and then the driving tooth structure in the driving groove 82 engages with the teeth 41 on the outer wall of the rotating ring 4 again, and the flip shovel blade 3 scoops up the fruit in the next arc-shaped area. The above process is repeated, and the flip shovel blade 3 can turn over all the fruits on the top of the loading plate 2. Through asynchronous rotation control, not only the cost of the equipment is saved, but also the rotation and flipping rhythm of the flip shovel blade 3 can be accurately adjusted, making the flipping of the fruit more flexible and efficient during the drying process.

[0037] In this embodiment, one end of the shovel arm 5 extending in the rotating ring 4 is connected to the limit plate 51, and a torsion spring 52 is provided between the limit plate 51 and the inner wall of the rotating ring 4. When the arc-shaped driving tooth area in the tooth groove 85 drives the driving gear 7 to rotate through the external gear 72, the shovel arm 5 will rotate around its own axis. At this time, the torsion spring 52 will undergo elastic twisting. When the arc-shaped driving tooth area in the tooth groove 85 is not engaged with the external gear 72, at this time, under the action of the torsion spring 52, the shovel arm 5 drives the flipping shovel blade 3 to rotate in the opposite direction and reset, ensuring that the next flipping action is carried out smoothly, and the flipping shovel blade 3 does not need to be rotated 360° to reset, which facilitates the flipping of the flipping shovel blade 3 and improves the reliability and stability of the entire device.

[0038] In this embodiment, the outer wall of the extension column 71 is provided with a support plate 73 adapted to the inner cavity of the rotating ring 4. The support plate 73 is rotatably set in the inner cavity of the rotating ring 4 to achieve stable rotation of the extension column 71 along the axis of the rotating ring 4, avoiding shaking or offset of the extension column 71 during rotation, ensuring the stability of the engagement between the driving gear 7 and the driven gear 6, and thus ensuring the accurate movement of the flipping shovel blade 3.

[0039] In this embodiment, a drive shaft 86 is provided on the side of the drive disk 81 away from the convex ring 84, and the drive shaft 86 extends to the outside of the box body 1 on the side away from the drive disk 81. The drive shaft 86 serves as the power output end. The end of the drive shaft 86 extending out of the box body 1 is connected to a power source, such as a drive motor, which is not specifically drawn in the drawing. The power source is arranged outside the box body 1, which not only facilitates heat dissipation and ensures the normal use of the power source, but also facilitates integration and control with other equipment, thereby improving the degree of automation of the device.

[0040] In this embodiment, a number of loading trays 2 are arranged vertically and equidistantly to form a load-bearing unit. The box body 1 is provided with a number of vertical rods 9 for supporting the load-bearing units. The outer walls of the vertical rods 9 are equidistantly provided with a number of support frames 10 to support the bottoms of the several loading trays 2 in the load-bearing unit. The vertically arranged load-bearing units are conducive to making full use of the space in the box body 1, and more fruits can be placed in a limited space.
