[0002] The fruit conveying device has been widely applied in the market as an independent automatic device or an important pre-processing module of a fruit grading and sorting assembly line.

[0003] The fruit drying device in the assembly line adopts a fruit flow through the inside of a drying machine, and the fruit needs to stay in the inside of the drying machine for a period of time due to the drying efficiency. Therefore, under the premise of controlling the size of the drying machine and ensuring the fruit flux, the fruit is generally adopted to pass through at a low speed in parallel. In addition, the fruit needs to be rotated to ensure uniform drying.

[0004] The internal conveying structure of the current fruit drying assembly line is mainly based on rollers.

[0035] Figure 1 A schematic diagram showing the structure of a fruit conveying device according to an embodiment of the present disclosure is shown. As Figure 1 shown, the present disclosure provides a fruit conveying device, and the fruit 4 can be selected from fruits such as apples, oranges, pears, etc. The fruit conveying device can be used in a fruit processing line, and the conveying direction of the device is consistent with the fruit processing line. The conveying device can be arranged inside a fruit dryer. The device comprises:

[0036] The roller frame 1 comprises a first side plate 11 and a second side plate 12 arranged oppositely. In some embodiments, the first side plate 11 and the second side plate 12 are identical in shape. The first side plate 11 and the second side plate 12 are arranged in a vertical direction. The first side plate 11 and the second side plate 12 can be in the form of an n-shaped structure. The first side plate 11 comprises a first strip-shaped plate, a second strip-shaped plate, and a third strip-shaped plate, the length direction of the first strip-shaped plate and the second strip-shaped plate is in the vertical direction, the length direction of the third strip-shaped plate is in the horizontal direction, and the third strip-shaped plate is arranged above the first strip-shaped plate and the second strip-shaped plate. The second side plate 12 comprises a fourth strip-shaped plate, a fifth strip-shaped plate, and a sixth strip-shaped plate, the length direction of the fourth strip-shaped plate and the fifth strip-shaped plate is in the vertical direction, and the length direction of the sixth strip-shaped plate is in the horizontal direction. One end of the roller 2 is rotationally connected with the third strip-shaped plate, and the other end of the roller 2 is rotationally connected with the sixth strip-shaped plate. The first side plate 11 and the second side plate 12 can be arranged in parallel, and the rotation axis of the roller 2 can be perpendicular to the first side plate 11.

[0037] The roller 2 is used for supporting the fruit 4, and is arranged between the first side plate 11 and the second side plate 12. One end of the roller 2 is rotationally connected with the first side plate 11, and the other end of the roller 2 is rotationally connected with the second side plate 12. The curvature radius of the roller 2 gradually increases in the circumferential direction. The number of the rollers 2 is N, and N is an integer greater than or equal to 2. In some embodiments, the outer contour line of the cross section of the roller 2 comprises a first contour line segment and a second contour line segment. The two ends of the first contour line segment are connected by the second contour line segment. The first contour line segment is a variable-diameter circular arc spiral line. The cross section is taken by a plane perpendicular to the rotation axis. The second contour line segment is a straight line. The extension line of the second contour line intersects the rotation axis.

[0038] The driving motor 3 is in transmission connection with the roller 2. The driving motor 3 is used for driving the roller 2 to rotate in the transmission direction of the fruit 4 to convey the fruit 4. The driving motor 3 is used for driving the roller 2 to rotate in the direction in which the curvature radius gradually decreases. In use, the fruit 4 falls between the first roller 2 and the second roller 2. The rotation of the roller 2 drives the fruit 4 to rotate. In the process of one rotation of the roller 2, the contact point of the first roller 2 with the fruit 4 is higher and higher, and the contact point of the second roller 2 with the fruit 4 is lower. The first roller 2 pushes the fruit 4 into the space between the second roller 2 and the third roller 2, thereby achieving the advancement of the fruit 4.

[0039] The fruit conveying device provided by the embodiments of the present disclosure can apply a force to the fruit 4 in the direction of the rotation direction through the roller 2 with the curvature radius gradually decreasing. Compared with the prior art in which the fruit 4 added later pushes the fruit 4 added earlier to achieve conveying, the device can avoid the fruit 4 remaining by providing the fruit 4 with a driving force. At the same time, the device helps to reduce the collision between the fruits 4 and avoid the damage of the fruits 4.

[0040] In some embodiments, the rotation shafts of the N rollers 2 are arranged in a horizontal direction with a distance. The N rotation shafts are in the same horizontal plane. The distance between two adjacent rotation shafts is the same, and is greater than the maximum diameter of the roller 2. The distance between two adjacent rotation shafts can be 1.4 times the diameter of the fruit 4. The maximum diameter of the roller 2 and the diameter of the fruit 4 are greater than the distance between two adjacent rotation shafts. The difference between the maximum and minimum diameters of the roller 2 can be less than the diameter of the fruit 4.

[0041] The fruit conveying device provided by the embodiments of the present disclosure can help ensure that the fruit 4 will not fall during conveying by arranging the distance between adjacent rotation shafts according to the diameter of the fruit 4.

[0042] In some embodiments, the heights of the N rotation shafts gradually decrease in the conveying direction of the fruit 4. The N rotation shafts can be in the same plane. The distance between two adjacent rotation shafts is greater than the maximum diameter of the roller 2. The maximum diameter of the roller 2 and the diameter of the fruit 4 are greater than the distance between two adjacent rotation shafts in the horizontal direction.

[0043] The fruit conveying device provided by the embodiments of the present disclosure can help ensure smooth conveying of the fruit 4 by arranging the rotation shafts with a height difference.

[0044] The installation phases of the N rollers 2 are the same, the rotation shafts of two adjacent rollers 2 are connected by a first transmission chain 31, the rotation shafts of the rollers 2 are connected to the first transmission chain 31 by a synchronous wheel, and the first transmission chain 31 and the rotation shafts control the transmission of the rollers 2 two by two. The driving motor 3 is connected to the rotation shaft of one roller 2 by a second transmission chain 32, and the driving motor 3 is used to drive the N rollers 2 to rotate in the same direction and at the same speed. During rotation, the line connecting the point with the maximum curvature radius of the roller 2 and the rotation shaft is parallel to each other.

[0045] The fruit conveying device provided by the embodiments of the present disclosure can move the fruit 4 on the roller 2 to the next roller 2 along the rotation direction after one rotation of the roller 2, so that the fruit 4 is sequentially moved to complete conveying.

[0046] The roller 2 is a brush roller 2, the surface of the roller 2 is provided with brush hairs 21, and the ends of the brush hairs 21 away from the roller 2 are arranged in a wave shape along the length direction of the roller 2. The brush hairs 21 can be 5-20 mm long and made of plastic material, and the brush hairs 21 can be 10 mm long. The highest point of the wave-shaped brush separates the roller 2 into multiple channels, and the wave-shaped brush hairs 21 help to isolate the parallel fruits 4 and reduce the collision between the fruits 4. Isolating the parallel fruits 4 helps to ensure air circulation, which is especially suitable for drying the fruits 4.
