Description

TECHNICAL FIELD

[0001] The utility model relates to fruit and vegetable sorting technical field, concretely relates to a watermelon bearing and transporting tray with clamping fixing structure. TECHNICAL BACKGROUND

[0002] Watermelon is called " the king of melon ", and it is originally from Africa. It was introduced to Xinjiang in Tang Dynasty and to China in the Five Dynasties. Watermelon is cultivated in both north and south China, and China is the largest watermelon producer and consumer in the world. Before watermelon is sold, especially when it is exported, it is generally sorted to determine its quality grade.

[0003] At present, people generally use a scale to weigh by hand, and then package the watermelons according to their size and weight. However, the weight difference between the same grades is large, which increases the grading error. At the same time, manual sorting is time-consuming and labor-intensive, and the sorting efficiency is low, which is not conducive to large-scale operation of enterprises.

[0004] To solve the above problems, a device for sorting watermelons is disclosed in Chinese Utility Model Patent No. 202023238108.4, which includes a belt conveyor. The belt conveyor is fixedly connected with a limiting baffle at the upper end, and is detachably connected with a fruit tray. An internal quality detection machine is fixedly connected in the middle of the belt conveyor. A first sorting table is fixedly installed at the discharge end of the belt conveyor. A first balance wheel is movably connected inside the first sorting table. A first roller conveyor belt is fixedly installed on the right side of the first sorting table. A first sorting mechanism, a second sorting mechanism and a third sorting mechanism are fixedly connected from left to right outside the first sorting table. Weighing belt machines are arranged inside the first sorting mechanism, the second sorting mechanism and the third sorting mechanism. The device for sorting watermelons places the watermelons in the fruit tray with a recessed structure, thereby conveniently limiting the watermelons and preventing them from falling during sorting, ensuring the safety of the overall sorting process.

[0005] However, the above-mentioned prior art has the following technical problems: although the fruit tray is detachably connected to the belt conveyor for transporting watermelons, because the size of the fruit tray is fixed, there is a problem of high center of gravity when placing a watermelon that is too large. This may cause the watermelon to shake left and right during transportation, resulting in damage to the appearance of the watermelon, or even cause the watermelon to roll out of the fruit tray and be damaged, affecting the sorting efficiency.
