There are three wind tubes 4, and the wind tube 4 is rotatable. The bottom of the wind tube 4 is fixedly installed with a push rod 5 in a ring array with the central axis of the wind tube 4 as the axis, and the push rod 5 is connected to the interior of the wind tube 4. The lower end of the push rod 5 is provided with a horizontal blowing hole 6, and the bottom of the wind tube 4 is provided with a vertical blowing hole 7 in a ring array with the central axis of the wind tube 4 as the axis. The fruits and vegetables on the surface of the conveyor mesh belt 2 are blown horizontally through the horizontal blowing holes 6 on the push rod 5, and the fruits and vegetables are blown from top to bottom through the vertical blowing holes 7 at the bottom of the wind tube 4, which is used for multi-directional air drying of fruits and vegetables.

[0020] like Figures 1 to 3 As shown, air inlet pipes 8 are fixedly installed at equal intervals on the top of the fixed frame 3, and the tops of the three air inlet pipes 8 are connected through a main pipe. By connecting the air outlet of the fan with the main pipe, the bottom end of the air inlet pipe 8 is rotatably connected to the top of the wind tube 4 through a mechanical seal to prevent air leakage. The air inlet pipe 8 is connected to the interior of the wind tube 4, and a fixing rod 9 is fixedly installed on the middle part of the bottom end of the inner wall of the wind tube 4. A wind wheel 10 is fixedly installed on the top of the fixing rod 9, and the wind wheel 10 is arranged corresponding to the air inlet pipe 8.

[0021] During the air-drying process of fruits and vegetables, the outlet air of the air inlet pipe 8 will be blown onto the wind wheel 10, which will drive the wind tube 4 indirectly installed with the wind wheel 10 to rotate at the bottom end of the air inlet pipe 8, and will constantly change the air outlet angle of the horizontal blowing hole 6 of the pushing rod 5 installed on the wind tube 4, which will improve the air-drying effect of fruits and vegetables. At the same time, the rotating wind tube 4 drives the pushing rod 5 to rotate, which will constantly push the fruits and vegetables on the surface of the conveyor belt 2, further improving the air-drying effect of fruits and vegetables.

[0022] like Figures 1 to 3 As shown, the angles of the wind wheels 10 inside the two adjacent wind tubes 4 are set in opposite directions.

[0023] The three wind tubes 4 equipped with wind wheels 10 can be controlled to rotate alternately, which is used to facilitate the staggered rotation of the pushing rods 5 installed at the bottom ends of the three wind tubes 4, and is used to prevent the fruits and vegetables from being pushed to both sides of the conveyor belt 2 by the pushing rods 5 when the three wind tubes 4 rotate in the same direction.

[0024] like Figures 1 to 3 As shown, push plates 11 are symmetrically and slidingly installed at the positions of the wind tube 4 on both sides of the conveying frame 1, and the push plates 11 move intermittently. A limit rod 12 is symmetrically fixedly installed on one side of the push plate 11. Limit holes 13 are provided at the positions of the limit rods 12 on both sides of the conveying frame 1, and the conveying mesh belt 2 is slidably connected to the limit holes 13. An extrusion plate 14 is fixedly installed between the ends of the four limit rods 12 away from the push plate 11, and a spring 15 is fixedly installed on the outer side of the end of the limit rod 12 close to the extrusion plate 14, one end of the spring 15 is fixedly connected to the extrusion plate 14, and the other end of the spring 15 is fixedly connected to one side of the conveying frame 1, and a motor 16 is symmetrically fixedly installed at the middle of both sides of the conveying frame 1, and a cam 17 is fixedly installed at the output end of the motor 16, and the cam 17 is in extrusion contact with the extrusion plate 14.

[0025] The cam 17 is driven to rotate by the motor 16, and the squeezing plate 14 is squeezed by the protruding position of the cam 17, which will drive the limiting rod 12 connected to the squeezing plate 14 to slide along the trajectory of the limiting hole 13, and will drive the pushing plate 11 close to the inner walls of both sides of the conveying rack 1. At this time, the spring 15 is in an extended state. When the protruding position of the cam 17 cancels the squeezing plate 14, the spring 15 pulls the squeezing plate 14 to drive the pushing plate 11 to push the fruits and vegetables on both sides of the conveyor mesh belt 2, so as to push the fruits and vegetables accumulated on both sides of the conveyor mesh belt 2 to the bottom of the three air ducts 4, so as to prevent the accumulation of fruits and vegetables.

[0026] like Figures 1 to 3 As shown, a water collecting trough 18 is provided at the bottom of the conveying frame 1 , and the water collecting trough 18 is integrally formed through the design of the conveying frame 1 . A drain pipe 19 is fixedly installed at the middle of the bottom end of the conveying frame 1 , and the drain pipe 19 is connected to the water collecting trough 18 .

[0027] During the air-drying process of fruits and vegetables, the water on the fruits and vegetables will fall into the water collecting tank 18 through the conveyor mesh belt 2 and be drained in time through the drain pipe 19.

[0028] The utility model provides an air drying machine for fruit and vegetable processing, and the specific working principle is as follows:

[0029] When the device is in use, after washing and draining the fruits and vegetables, the fruits and vegetables are transported to the conveyor mesh belt 2 on the conveyor rack 1. The fruits and vegetables are continuously transported by the movement of the conveyor mesh belt 2. When the fruits and vegetables move to the fixed rack 3, the fan blows air into the air inlet pipe 8, and the wind is transported to the inside of the wind tube 4. The fruits and vegetables on the surface of the conveyor mesh belt 2 are blown horizontally through the horizontal blowing holes 6 on the push rod 5, and the fruits and vegetables are blown from top to bottom through the vertical blowing holes 7 at the bottom of the wind tube 4, so as to dry the fruits and vegetables in all directions.

[0030] During the air-drying process of fruits and vegetables, the air from the air inlet pipe 8 will blow on the wind wheel 10, which will drive the wind tube 4 indirectly installed with the wind wheel 10 to rotate at the bottom end of the air inlet pipe 8, and will constantly change the air outlet angle of the horizontal air hole 6 of the push rod 5 installed on the wind tube 4, which will improve the air-drying effect of fruits and vegetables. At the same time, the rotating wind tube 4 drives the push rod 5 to rotate, which will constantly push the fruits and vegetables on the surface of the conveyor belt 2, further improving the air-drying effect of fruits and vegetables. In this process, the cam 17 is driven to rotate by the motor 16, and the cam The protruding position of the wheel 17 squeezes the squeezing plate 14, which will drive the limiting rod 12 connected to the squeezing plate 14 to slide along the trajectory of the limiting hole 13, and will drive the pushing plate 11 close to the inner walls of both sides of the conveyor frame 1. At this time, the spring 15 is in an extended state. When the protruding position of the cam 17 cancels the squeezing plate 14, the spring 15 pulls the squeezing plate 14 to drive the pushing plate 11 to push the fruits and vegetables on both sides of the conveyor mesh belt 2, which is used to push the fruits and vegetables accumulated on both sides of the conveyor mesh belt 2 to the bottom of the three air ducts 4, so as to prevent the accumulation of fruits and vegetables.
