[0046] The use and principle of the above-mentioned adaptive and adjustable fruit support device:

[0047] The fruit holder wheel is composed of a fruit holder wheel base and a fruit holder wheel cover. The fruit holder wheel base is made of hard plastic material such as PP, and has a two-section design. One section is a large cylindrical shape that contacts the friction drive belt, and the other section is a small cylindrical shape that is tightly fitted with the fruit holder wheel cover. Four sliding grooves are designed in the middle hole of the fruit holder wheel base. The fruit holder wheel cover is made of soft and flexible material such as rubber, and has a conical shape that contacts the fruit.

[0048] The rotating shaft is made of hard plastic material such as ABS, and is designed as a cylindrical shape. Four sliding rails are designed on the circumference of the rotating shaft to connect with the fruit holder wheel and allow axial sliding.

[0049] The tension spring is connected with the fruit holder wheel bases on both sides. When the two fruit holder wheels are pulled apart under the action of external force, the tension spring is stretched. When the external force is removed, the tension spring returns to its original length.

[0050] The fruit holder wheel support assembly includes a support, a spring, a guide column, a retaining ring, and a support piece. The support piece is connected with the support through a connecting piece, and the spring is connected with the guide column. The guide column is installed in the guide hole of the support, and the retaining ring is screwed in. The guide column can move back and forth in the guide hole under the action of external force and the spring force. One end of the guide column abuts against the rotating shaft of the fruit holder wheel assembly, and the rotating shaft can be reset under the action of the spring force. The support is made of hard plastic material such as ABS. Keyway holes are designed to facilitate the positioning of the rotating shaft, and guide holes are designed to facilitate the movement of the guide column.

[0051] Large fruits generally have a certain weight. When the fruit falls between the fruit holder wheel support assembly and the fruit holder wheel assembly, the tension spring is stretched, and the distance between the two fruit holder wheels is pulled apart. The spring is compressed, and the distance between the fruit holder wheel and the support is pulled apart. In this way, the center of gravity of the fruit will move downward, and it will not be easy to fall off the fruit holder device. When the fruit is removed from the fruit holder device, the fruit holder wheel returns to its original position under the action of the spring.

[0052] In summary, the above-mentioned self-adaptive adjustable fruit holder device can adapt to fruits of different sizes in the same category, and can adapt to fruits of different categories within a certain range. It has strong applicability, avoids the influence of small fruits on the detection results, and avoids mechanical damage and the influence on the work efficiency caused by the falling of large fruits from the fruit holder.

[0053] The above-mentioned embodiments are only examples of the present application, and do not limit the patent scope of the present application. Any equivalent transformation or direct or indirect application in related technical fields based on the content of the specification and drawings is also included in the patent protection scope of the present application.
