Small convenient-to-move soil bin test platform

Abstract

The invention discloses a small convenient-to-move soil bin test platform, and belongs to the field of agricultural machinery. The platform is mainly characterized by comprising a pulley, a bracket, apower measuring instrument, a decelerating stepping motor, a sliding rail, a moving plate, a stirring paddle, a fixed plate, a humidity sensor, a controller, strain gauges and the like. The stirringpaddle can guarantee the consistency of soil parameters for different intervals and during multiple tests in a soil bin. The change of the fixed position of the moving plate can adjust the height of soil in the soil bin, so that the maximum tillage depth of the soil bin and the soil penetration depth of an agricultural machine are changed. The strain gauges uniformly arranged on the fixed plate can be used for researching strain characteristics of the soil at different depths during working of the agricultural machine. The test platform is small in size and simple in structure, adopts a sectional material convenient to dismount, has the characteristics of being simple in structure, convenient to move, small in size and low in cost, and can overcome the defect that most of colleges or scientific research institutions have no soil bins to use at the present stage.

Description

technical field [0001] The invention relates to a soil tank test platform, in particular to a small portable soil tank test platform, which belongs to the field of agricultural machinery. Background technique [0002] At present, my country's agricultural mechanization is in the golden period of historical development, and the demand for domestic agricultural machinery is strong. At the same time, the pace of upgrading and updating of the agricultural machinery industry is also accelerating, and the speed of research and development of new agricultural machinery is constantly increasing. However, the field test of agricultural machinery will be restricted by many conditions such as farming time and seasonality. At the same time, the contrast of the field test is poor, and the precision and accuracy of the obtained data are not enough. [0003] The terrain of Asia is complex and diverse, with mountains, plateaus and hills occupying an important part, accounting for about 3 / 4 ...

AI Technical Summary

Problems solved by technology

In my country, 69.3% of the cultivated land is distributed in hills, mountains and plateau areas, which is not conducive to large-scale mechanized operations

At present, soil tank test platforms are mainly distributed in scientific research institutions with strong scientific research strength, and mainly medium and large soil tank test platforms (more than 50 meters in length and more than 3 meters in width). The problem of shortage of funds makes it difficult to build medium and large soil tank test platforms, which seriously restricts the development of agricultural machinery

[0004] For the medium and large soil tank test platforms built by some colleges and universities at this stage, it is difficult to ensure the consistency of soil parameters in different intervals and repeated tests in the soil tank, and it is inconvenient to move, and the difference in soil stress characteristics during layered cultivation is not considered. characteristics, and complex structure and operation, high power consumption
