Fruit diameter measuring device

Abstract

The invention discloses a fruit diameter measuring device. The device comprises an upper shell which is provided with a first opening end with a downward opening, a lower shell which is hinged to theupper shell through a hinge shaft and is provided with a second opening end with an upward opening, a tension sensor which is set in a containing groove, a controller which is arranged in the accommodating groove and is electrically connected with the tension sensor, a display device which is arranged on an outer surface of the upper shell and is electrically connected with the controller, and a battery which is arranged in the containing groove and is electrically connected with the tension sensor, the controller and the display device, wherein a first elastic belt is arranged at the openingend, a second elastic band is arranged at the second opening end, a containing groove is formed in the hinge shaft, and one end of the first elastic band and one end of the second elastic band pass through a cavity wall of the containing groove to be connected with the tension sensor to measure elasticity values of the two elastic bands. According to the device, the problem of easy mechanical damage to a surface of fruit due to contact between a vernier caliper and a fruit skin can be reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural measurement, in particular to a fruit diameter measuring device. Background technique [0002] In agricultural production and agricultural research, it is necessary to pay attention to the change of the diameter of the plant fruit frequently, and provide a reference for knowing the status of the placed fruit, which has a certain reference value for agricultural production or research. [0003] When actually measuring the diameter of the placed fruit, a vernier caliper is usually used for measurement, and the contact between the vernier caliper and the fruit epidermis is likely to cause mechanical damage to the fruit surface, especially for the fruit in the developing stage, fruit bruises are likely to cause fruit wounds to rot. [0004] Therefore, how to provide a fruit diameter measuring device that can reduce mechanical damage to the fruit surface during measurement is an urgent problem to ...
