Fruit clamping device and method for measuring jujube falling impact force

Abstract

In order to research the falling characteristic of small fruits, such as jujubes and the like, in an effective and low-cost way, the invention provides a simple and low-cost fruit clamping device and method. The fruit clamping device comprises a pedestal, a height adjusting device, a connecting rod, a left clamping face, and a right clamping face. The height adjusting device is used for adjusting the fruit falling height required by an experiment. The connecting rod is used for fixing the left clamping face and the right clamping face and is connected with the height adjusting device. The left clamping face and the right clamping face are aluminum alloy slices and are in S shapes. In operation, the height adjusting device is adjusted to a required height according to an experiment requirement. Then a fruit is placed between the left clamping face and the right clamping face and the outer ends of the left clamping face and the right clamping face are clamped by a hand simultaneously in order to fix the fruit. The outer ends of the left clamping face and the right clamping face are loosened and the left clamping face and the right clamping face are restored to a natural state by means of the elasticity of the left clamping face and the right clamping face so that the fruit can be released. The fruit clamping device and method is adjustable in falling height, stable and accurate in fruit fixation.

Description

technical field [0001] This patent relates to a fruit clamping device and method for jujube fruit drop impact force measurement. Background technique [0002] When carrying out the fruit drop experiment research, the way of vacuum suction or tray is usually used to fix the fruit. However, due to the small size of jujube fruit, it is easy to cause the fruit to roll when the tray is opened, resulting in a change in the orientation of the fruit, so the experiment cannot be carried out accurately. And vacuum suction method needs air compressor, vacuum generator and sucker, and cost is higher. This patent proposes a simple and low-cost fruit clamping device. Contents of the invention [0003] Realize above-mentioned experimental purpose to be realized by following technical scheme: [0004] The patent includes a base, a height adjusting device, a connecting rod, a left clamping surface, and a right clamping surface. [0005] The above-mentioned height adjusting device is us...
