Fatigue testing machine for sugarcane detrashing machine detrashing element

Abstract

The invention discloses a fatigue testing machine for a sugarcane detrashing machine detrashing element. The testing machine comprises a driving component, a loading component which is arranged at one side of the driving component, a measuring component which is arranged at the other side of the driving component, and a counting component which is connected with the driving component in a mutual matching way. The driving component is used for providing driving force to drive a detrashing element sample to rotate. The loading component provides different interleaving depths for testing. The measuring component is used for detecting working length and impact force of the detrashing element sample. The counting component is used for recording the service life (cycle index) of the sample and can also judge fatigue fracture of the sample and stop counting at the time of fracture. According to the testing machine, the optimal selection of rotating speed and interleaving depth of a sugarcane detrashing machine can be obtained through analysis and summary of experimental data together with the actual situations so that the testing machine has important significance for reducing consumption of the detrashing element, enhancing the service life and detrashing efficiency of the sugarcane detrashing machine and reducing cost when the sugarcane detrashing machine normally works.

Description

technical field [0001] The invention relates to a fatigue testing machine, in particular to a fatigue testing machine for leaf stripping elements of a sugarcane leaf stripping machine. Background technique [0002] Fatigue is a phenomenon in which materials, parts and components are subjected to cyclic loading, causing local permanent damage at some point or points, and forming cracks after a certain number of cycles, and even further expanding the cracks until they are completely broken. Fatigue is one of the main factors for material damage or failure. Therefore, fatigue testing of mechanical products or materials is carried out using fatigue testing machines to obtain the fatigue characteristics of mechanical products or materials. It is of great significance to the design of mechanical parts and improve the quality of mechanical products. Significance. [0003] Sugarcane leaf stripping is an important step in sugarcane harvesting, and the life of the leaf stripping elem...

AI Technical Summary

Problems solved by technology

Since the status, material, size, etc. of the stripping elements have been determined, the fatigue testing machines currently on the market cannot perform fatigue tests on the stripping elements, and the fatigue testing machines on the market are relatively primitive, and the mechanical and electronic parts account for The specific gravity is relatively small, only manual control can be used, the operation is complicated, and the measurement accuracy is low
