Abstract
In order to efficiently carry out the research of hairiness fruit roll-off characteristic, this patent proposition experimental provision a kind of easy to operate and practical and method.This patent includes base, height regulation handle, pallet controlling switch, fruit pallet, falls disk, sensor, signal picker, signal analyzer.Fruit pallet can opening and closing left and right, for holding and discharging fruit；Pallet controlling switch is used for the folding for controlling fruit pallet；Height regulation handle is used for the drop height for adjusting fruit；The active force that falling disk and sensor is used to drop fruit is converted to electric signal；Signal picker and signal analyzer are used to gather and analyze data.The advantage of this patent：Drop height is adjustable, fruit fixing-stable, it is ensured that experiment it is accurate.
Description
Technical field
This patent is to be related to a kind of crash tests apparatus and method studied for hairiness fruit roll-off characteristic.
Background technology
Fruit harvest, sorting, processing, packaging, handling, in transportation, can all produce fruit and work members, fruit with
Collision impact between fruit, inevitably produces mechanical damage.Wherein drop impact be cause fruit damage it is main
The reason for.Mechanical behavior of the fruit during drop impact is studied, to understanding fruit drop impact micromechanism of damage, science is taken
Drop impact damage in effective technical measures control fruit operation process, improves fruit storing quality significant.Due to
The fruit surface hairiness such as hairiness fruit, it is impossible to fixed fruit by the way of vacuum attraction, therefore this patent proposes that one kind is adopted
The method for fixing and discharging hairiness fruit with pallet folding technology.
The content of the invention
In order to efficiently carry out hairiness fruit（Such as Kiwi berry）The research of roll-off characteristic, this patent propose it is a kind of easy to operate and
Practical experimental provision and method.
Realizing above-mentioned experiment purpose is realized by following technical scheme：
This patent includes base, height regulation handle, pallet controlling switch, fruit pallet, falls disk, sensor, signal acquisition
Device, signal analyzer.
Above-mentioned fruit pallet can opening and closing left and right, for holding and discharging fruit.
Above-mentioned pallet controlling switch is used for the folding for controlling fruit pallet.
Above-mentioned height regulation handle is used for the drop height for adjusting fruit.
The above-mentioned active force for falling disk and sensor for fruit to be dropped is converted to electric signal.
Above-mentioned signal picker and signal analyzer are used to gather and analyze data.
The advantage of this patent：Drop height is adjustable, fruit fixing-stable, it is ensured that experiment it is accurate.
Brief description of the drawings
This patent is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is a kind of hairless fruit drop impact test system.
Embodiment
In Fig. 1, a kind of hairiness fruit dropping shock force measuring device of this patent, including base（1）, height regulation hand
Handle（2）, pallet controlling switch（3）, fruit pallet（4）, fall disk（5）, sensor（6）, signal picker（7）, signal analysis
Instrument（8）.
Specific work process：
First according to requirement of experiment, height regulation handle is adjusted（2）To required height；Then pallet controlling switch is passed through（3）Close
Upper fruit pallet（4）, fruit is placed on pallet（4）On；Again by signal picker（7）Set to required signal acquisition frequency；
Afterwards, pallet controlling switch is pressed（3）, make fruit pallet（4）Open, fruit, which is freely fallen to, falls disk（5）, sensor（6）
It is electric signal by pressure conversion, passes to signal picker（7）, signal analyzer is transferred to after data preservation（8）Analyze data.
