Abstract

The invention discloses a falling weight type nut mechanical characteristic parameter testing experiment table. LabVIEW is adopted as a software platform for implementing a detection and control process, and the experiment table is used for detecting mechanical hull breaking characteristics of nut products. The experiment table comprises a high-speed camera, a falling weight experiment table, a data acquisition system and a PC. The falling weight experiment table serves as a carrier, an analogue signal acquired by a sensor is transmitted to the PC through the data acquisition system, a program of the PC (upper computer) is written by virtue of the software LabVIEW, filtering compensation conditioning is performed on the signal, and practical mechanical characteristic parameters such as hull breaking impact force, magnitudes of speed before and after impact and an acceleration, hull breaking energy, hull breaking power and an impact height are finally calculated by virtue of a LabVIEW software environment, and are directly fed back in form of oscillogram. The experiment table is simple in structure, high in automation degree and stable and reliable in performance, and an important theoretical basis is provided for research and development of hull breaking and nut extraction equipment for agricultural products such as nuts.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to an electromechanical control detection test bench, which uses LabVIEW as a software platform to realize detection and control experimental equipment, specifically a drop hammer type mechanical characteristic parameter test bench. Background technique [0002] In recent years, with the development of network technology, the sale of nuts agricultural products on the Internet has made the development of nut shelling and kernel extraction technology the focus of many businesses. The technology of cracking shells and extracting kernels of nut agricultural products has always been a major technical problem in related fields. Most of the devices for cracking shells and extracting kernels currently on the market have the disadvantages of low shell breaking rate and high damage rate. The mechanical properties of shell breaking of similar agricultural products are unknown. The...
