[0001] The utility model relates to the technical field of agricultural product processing equipment, in particular to a fruit support device. Background Art

[0002] With the improvement of people's living standards, the quality requirements for fruits are getting higher and higher; more and more advanced technologies such as machine vision and spectroscopy are used to detect the external and internal quality of fruits. During the detection process, the fruits need to be transported and turned over so that the fruits can be detected in all directions. At present, fruit trays are basically used to carry and transport fruits to ensure the integrity and stability of fruits during the sorting process. In the fruit sorting process, since different types of fruits have different shapes, sizes and weights, choosing a suitable fruit tray is crucial to ensuring sorting efficiency and fruit quality; but the existing fruit trays are of fixed size. When different types of fruits need to be sorted, replacing the fruit tray becomes a necessary step.

[0003] Replacing the fruit tray device to adapt to different types of fruits requires processing and manufacturing fruit tray devices of various specifications, which has a large investment cost and high management costs such as storage of the fruit tray device.

[0004] Therefore, it is necessary to find a fruit support device that can automatically adjust according to the size of different types of fruits to adapt to the sorting of fruits of different sizes, to prevent the fruit support device from being smaller than the fruit, causing the fruit to fall off the fruit support device during the sorting process and causing mechanical damage to the fruit; to prevent the fruit support device from being larger than the fruit, causing poor contact between the fruit and the fruit support device during the sorting process and failing to rotate effectively, failing to conduct all-round inspection, affecting work efficiency and inspection results.

[0009] Furthermore, in the above-mentioned fruit support device, a horizontal guide hole is provided on the side wall of the key slot hole, and the elastic member includes a guide column and a spring; a guide column is passed through the guide hole, and the spring is sleeved on the guide column, and an annular boss is provided in the circumference of one end of the guide column close to the rotating shaft, and one end of the spring abuts against the side wall, and the other end abuts against the annular boss on the guide column.

[0010] Furthermore, in the above-mentioned fruit tray device, one end of the guide column away from the rotating shaft passes through the side wall of the keyway hole and is threadedly connected to a clamping ring.

[0011] Furthermore, in the above-mentioned fruit support device, the fruit support wheel includes a fruit support wheel base and a fruit support wheel sleeve, the fruit support wheel base includes a large cylindrical section and a small cylindrical section, and the fruit support wheel sleeve is conical, with a through hole at the center for sleeve-connecting the small cylindrical section.

[0040] The fruit support wheel assembly comprises a rotating shaft 1, a tension spring 2 and two fruit support wheels 3 arranged on the rotating shaft 1; the fruit support wheels 3 are axially slidably sleeved on the rotating shaft 1, the tension spring 2 is sleeved on the rotating shaft 1, and the two ends of the tension spring 2 are respectively connected to a fruit support wheel 3;

[0041] The fruit support wheel bracket 4 assembly includes a bracket 4, and the bracket 4 includes two support arms located at both ends of the rotating shaft 1, each of the support arms is provided with a key slot hole 41 for placing one end of the rotating shaft 1, and a horizontal guide hole is provided on the side wall of the key slot hole 41, and the elastic member includes a guide column 43 and a spring 42; a guide column 43 is passed through the guide hole, and the spring 42 is sleeved on the guide column 43, and an annular boss is provided in the circumference of one end of the guide column close to the rotating shaft, one end of the spring 42 abuts against the side wall, and the other end abuts against the annular boss on the guide column 43; the end of the guide column 43 away from the rotating shaft 1 passes through the side wall of the key slot hole 41 and is threadedly connected to a clamping ring.

[0042] The fruit wheel 3 includes a fruit wheel base 31 and a fruit wheel sleeve 32. The fruit wheel base 31 includes a large cylindrical section and a small cylindrical section. The fruit wheel sleeve 32 is conical, and a through hole for the small cylindrical section is provided in the center. The fruit wheel base 31 is provided with a middle hole for the shaft 1 to pass through along the central axis. The wall of the middle hole is provided with a slide groove 32 along the axis direction. The shaft 1 is provided with a slide rail 11 adapted to the slide groove 32. Four slide grooves 32 along the axis direction are evenly provided on the wall of the middle hole.

[0043] The use and principle of the above-mentioned fruit support device:

[0044] The fruit wheel is composed of a fruit wheel base and a fruit wheel sleeve. The fruit wheel base is made of hard plastic materials such as PP, and has a two-section design. One section is a large cylinder in contact with the friction drive belt, and the other section is a small cylinder tightly fitted with the fruit wheel sleeve. There are 4 slide grooves in the middle hole of the fruit wheel base. The fruit wheel sleeve is made of soft and flexible materials such as rubber, and has a conical shape designed to contact the fruit.

[0045] The rotating shaft is made of hard plastic materials such as ABS, is designed to be cylindrical, and is designed with 4 slide rails around the circumference so as to be connected to the fruit supporting wheel and slide in the axial direction.

[0046] Tension spring. The tension spring is connected to the fruit support wheel base on both sides. When the distance between the two fruit support wheels is enlarged under the action of external force, the tension spring is stretched. When the external force is removed, the tension spring retracts to its original length.

[0047] The fruit wheel bracket assembly includes a bracket, a spring, a guide column, a clamp, a support, etc. The support is connected to the bracket through a connector, the spring is connected to the guide column, and then installed into the guide hole of the bracket. The clamp is screwed in, and the guide column can reciprocate along the guide hole under the action of external force and spring force; one end of the guide column is against the rotating shaft of the fruit wheel assembly, and the rotating shaft can be reset under the action of the spring force. The bracket is made of hard plastic materials such as ABS. A keyway hole is designed to facilitate the change of the rotating shaft position; a guide hole is designed to facilitate the movement of the guide column.

[0048] Larger fruits are generally heavier. When the fruit falls between the fruit support wheel bracket assembly and the fruit support wheel assembly, the tension spring is stretched and the fruit support wheels on both sides are separated; the elasticity is compressed and the distance between the fruit support wheel and the bracket is separated, so that the center of gravity of the fruit will move downward and it is not easy to fall off the fruit support device; when the fruit is removed from the fruit support device, the fruit support wheel returns to its original position under the action of elastic force.

[0049] In summary, the above-mentioned fruit tray device can adapt to fruits of different sizes in the same category and different categories of fruits within a certain range. It has strong applicability and can avoid small fruits from being unable to rotate and affecting the detection results, and large fruits from falling off the fruit tray and causing mechanical damage and affecting the operation efficiency.
