[0029] Of course, other kinds of melons and fruits can be placed on the carrying trays 11 to be weighed and graded, so that the device has good applicability and versatility.

[0030] Further, the weighing and grading assembly 12 further comprises a spacing expansion mechanism 121. The outlet end of the spacing expansion mechanism 121 is connected with the inlet end of the transportation weighing module 1221, which is used to expand the distance between two adjacent carrying trays 11 and transport the carrying trays 11 and the watermelons placed on the trays to the transportation weighing module 1221 to avoid the transportation weighing module 1221 from collecting the weight information of multiple watermelons at a time.

[0031] In the embodiment, the transportation weighing module 1221 is a transportation conveyor belt, and a gravity sensor 1222 is installed below the transportation conveyor belt to weigh the carrying trays 11 and the watermelons placed on the trays when the carrying trays 11 and the watermelons are transported through the gravity sensor 1222.
