AI Technical Summary
Technical Problem
Traditional pear weighing and grading devices lack a buffering mechanism, making the pears susceptible to impact damage during the fall, especially for thin-skinned varieties.
Method used
A multi-level buffer system is composed of flexible components such as flexible buffer nets, buffer pads, and rubber protrusions to gradually absorb the impact force during the fall of the pear, and the system is combined with a support mechanism to achieve graded absorption.
Benefits of technology
This effectively prevents damage to the pear's skin and flesh, ensuring fruit quality and enabling accurate grading of the pears.

Abstract
This utility model relates to the technical field of pear sorting, and proposes an automatic weighing and grading device for pears, including a frame and a weighing unit. A conveyor belt surrounds the frame, and a weighing pan is mounted on the conveyor belt. The end of the weighing pan facing outwards from the conveyor belt is an open structure, and the bottom of this open end is hinged to the conveyor belt. A support mechanism is located on the inner side of the conveyor belt, capable of lifting the other end of the weighing pan. A feeding mechanism is located on the outer side of the conveyor belt, opposite to the support mechanism. The feeding mechanism includes a flexible buffer net fixed to the frame via baffles on both sides, a first buffer plate, and a second buffer plate. The beneficial effects of this application are: by setting a feeding mechanism at the feeding point and utilizing a multi-stage buffer system composed of flexible components such as a flexible buffer net, buffer pad, and rubber protrusions, the impact force received by the pear during its fall is gradually absorbed, avoiding damage to the skin or flesh due to collision, thus ensuring fruit quality.
