Abstract

The invention discloses a fruit-and-fruit-stem binding force testing device. The fruit-and-fruit-stem binding force testing device comprises an electric pushing rod, an upper support, clamping and fixing devices, a lower support, a stretchable mechanism, a tension sensor and a fruit clamping device. One end of the upper support and a base of the electric pushing rod are fixed through a connecting arm, and the free end of the electric pushing rod and the lower support are fixed; at least three clamping and fixing devices are linearly arranged on the lower surface of the upper support, and the clamping and fixing devices located in the middle are connected with the upper support in a sliding mode; the stretchable mechanism, the tension sensor and the fruit clamping device are sequentially connected to the lower support upwards, and an opening part of the fruit clamping device is upward. The fruit-and-fruit-stem binding force testing device is small in structure size and convenient to carry and operate; as branches are difficult to fix, the multiple adjustable clamping and fixing devices are designed, the binding force between different-normality-degree fruits and different-normality-degree fruit stems can be conveniently, rapidly and accurately tested, and the theoretical basis is provided for determining of an automatic picking mode of an automatic picking machine.

Description

Technical field: [0001] The invention relates to the technical field of agricultural testing, in particular to a device for testing the binding force of fruit stems. Background technique: [0002] At present, various jujubes and cherries are still picked manually. Due to the small size of jujubes and cherries, they require a lot of labor, resulting in high labor costs included in the final selling price. Especially like Lingwu long jujube, due to the long thorns on the branches, the picking efficiency is low and the fruits are easy to collide and damage each other, which makes the development of Lingwu long jujube economic forest fruit industry severely hindered. The realization of high-efficiency automatic picking machinery must first determine the optimal picking method according to the characteristics of the fruit and picking habits. The determination of the automatic picking method of the automatic picking machine is closely related to the binding force between the frui...
