The research of the mechanical characteristic of soil-engaging components such as ploughing unit has great significance.The leading indicator of general ploughing unit power performance is a traction power, and traction power is by tractive resistance, haulage speed decision.These all are converted into the last processes and displays of electric quantity signal by sensor with non-electric charge quantity signalling and come out, and the mensuration of other mechanics parameter is similar to the method.Novel in order to develop, be fit to arid and semi-arid area usefulness, minimal till, subsoiler tool and cultivating equipment, press for the reliable load data that this respect is provided.But, on market, be difficult to buy at present six fens ready-made force measuring devices, must design voluntarily according to the needs of oneself.
Summary of the invention
The purpose of this utility model is to provide a kind of soil bin test plough body six fens force measuring devices, can gather test figures such as soil-engaging component tractive resistance, side force, soil resistance, moment of torsion, rotary power, traction powers, single plow is carried out force analysis, for the warping surface of plow bottom designs, the whole stress balance analysis of plow frame structural strength and farming unit etc. provides raw data, this apparatus structure is compact simple, be convenient to install and use, versatility is good.
The purpose of this utility model is achieved in that six fens force measuring devices of a kind of soil bin test plough body, comprise plough body and differential full bridge measurement circuit, the back side level of plough body affixed connector once, the end face of following connector is connecting an elastic body that extends upward layout by lower flange, elastic body upper end by upper flange affixed hitch frame; Said elastic body comprises a pipe, uniform from top to bottom interval is being provided with some groups of pull pressure sensor on the outer circumference surface of pipe, every group of pull pressure sensor all linked to each other with said metering circuit by splicing ear by signal wire, and every group of pull pressure sensor all formed along pipe periphery resistance strain gage uniformly at intervals by four.
Said pull pressure sensor is divided into spaced apart from top to bottom 5 groups, and the resistance strain gage in the 3rd group of middle sensor at right angles arranges between any two, and structure is in angle of 45 degrees all and between the pipe axis for each resistance strain gage; At right angles arrange between any two near the resistance strain gage in the 5th group of sensor of plough body, rectangular two resistance strain gages arranging, axial arranged along pipe always wherein, and another is along the radial arrangement of pipe.The 1st group, the 2nd group of number and the 4th group of sensor are all arranged along the axis direction of pipe from top to bottom along pipe.
Said splicing ear is for to be made of aviation plug, and aviation plug is installed on the terminal block, and terminal block is installed on the pipe.
When the utility model uses, it is installed in tractor rear by hitch frame, the plough body service part under external force, produce elastic deformation based on elastomeric resistance-strain type pull pressure sensor, produce distortion even stick on the resistance strain gage on pipe surface, after the resistance strain gage distortion, its resistance will change (increase or reduce), through corresponding metering circuit this resistance variations is converted to electric signal (voltage or electric current) again, thereby finished the process that external force is transformed to electric signal, measured three component and three moments of plough body.
This device can also be to deep soil loosing shovel except measuring six component of plough body, and the performance of soil-engaging components such as intertillage shovel, plough is tested.
Device characteristic: 1, can dynamically onlinely measure three component and three moments simultaneously, promptly gather with six 12 AD analog channels.2, precision height, working stability, reliability height, and can under rugged surroundings, work.3, simple and compact for structure, can articulate multiple tillage implement makes a service test, can gather test figures such as soil-engaging component tractive resistance, side force, soil resistance, moment of torsion, rotary power, traction powers, single plow is carried out force analysis, for the warping surface of plow bottom designs, the whole stress balance analysis of plow frame structural strength and farming unit etc. provides raw data, be convenient to install and use, versatility is good.
