Force measuring frame for agricultural machinery operation part

Abstract

The invention provides a force measuring frame for an agricultural machinery operation part and belongs to agricultural machinery test equipment. A three-point suspension assembly is assembled at thefront end part of a fixed frame; a force measuring movable frame is hinged, suspended and arranged at the lower side part of the fixed frame through vertical tension-compression sensors A, B and C, horizontal and longitudinal tension-compression sensors A and B and a horizontal and transverse tension-compression sensor in a manners of vertical up-and-down movement, horizontal and longitudinal movement and horizontal and transverse movement; the vertical tension-compression sensors A, B and C are vertically arranged and are in triangular configuration in a horizontal plane as a whole; the horizontal and longitudinal tension-compression sensors A and B are horizontally and longitudinally assembled; and the horizontal and transverse tension-compression sensor is horizontally and transverselyassembled. According to the force measuring frame, the three-dimensional and omni-directional force detection of the measured agricultural machinery operation part is achieved; and the force measuringframe has the characteristics of being novel and reasonable in structure, comprehensive and accurate in force detection of the agricultural machinery operation part, high in accuracy, good in generalization performance, easy and convenient to use and operate, and fast.

Description

technical field [0001] The invention belongs to agricultural machinery test equipment, and mainly relates to a force measuring frame suitable for agricultural machinery operation parts such as plows, shovels, and ditch openers. Background technique [0002] At present, when the soil tank test bench is used to test the performance of various agricultural machinery operating parts such as plows, shovels, and openers, the agricultural machinery operating parts to be tested are directly rigidly connected and installed on the soil tank test bench. In order to detect the stress of the inspected operating parts, it is necessary to select and mount multiple strain gauges on different positions according to the different structures of the inspected agricultural machinery operating parts. There are problems such as cumbersome mounting of strain gauges and low test and detection efficiency. Contents of the invention [0003] The purpose of the present invention is to solve the proble...
