Embodiment 1

[0045] The soil tank test platform car of the present embodiment has a structure such as Figure 1 to Figure 22 As shown, the present invention is made up of soil tank system 1, test tractor 2 and two-wheel test device 3.

[0046] The soil tank system includes the soil tank body, which is made of concrete pouring, and No. 10 hot-rolled I-shaped channel steel is installed on both sides as the driving track of the tractor. The upper surface of the channel steel is flush with the upper surface of the soil tank, and the channel steel and the track are fixed with countersunk bolts. At the same time, a water inlet pipe made of Φ40mm PVC pipe is placed along the long side of one side of the soil tank. In the direction of the same busbar of the water inlet pipe, a through hole is opened at an interval of 1m for installing the nozzle. The water inlet of the nozzle is controlled by the main water inlet valve, and each nozzle can be switched on and off independently to ensure that the ...

Abstract

The invention relates to a soil bin test trolley. The soil bin test trolley includes a soil bin system, a test tractor and a double-wheel test device; the front end of the test tractor is provided with the double-wheel test device; and the test tractor and the double-wheel test device perform reciprocating motion along the soil bin system. With the soil bin test trolley of the invention adopted, the stress-strain of a tire and mechanical parameters of agricultural implements such as a plough and a rotary cultivator under different experimental factors can be tested, and the problem of influence of the vibration of traction equipment on measurement results existing in an existing test system can be solved. The soil bin test trolley has the advantages of controllability of test conditions and environmental factors, convenient measurement of test data and parameters, high measurement precision, high test repeatability, high driving ability, accurate and reliable control, flexible and convenient test and coherent data acquisition.

Description

technical field [0001] The invention relates to an automatic control test equipment integrating electric drive technology, hydraulic transmission technology, PLC control technology and LabVIEW virtual instrument technology, in particular to a soil tank test platform. Background technique [0002] At present, in the design process of agricultural machinery, the lack of good test conditions is one of the main reasons for hindering innovation. Due to factors such as uncontrollable farmland environment, vibration of driving equipment, and agricultural weather, the development of new agricultural machinery is very slow. Vehicle ground mechanics is a subject that attaches equal importance to experiment and theory. Through the research on tire passability, road friendliness and other aspects, the coupling mechanism between tire and ground is analyzed. Affected by natural conditions and test accuracy, the test link in this field is still relatively weak, and the vibration of tractor...
