Description
Technical Field
The utility model belongs to the technical field of agricultural machine, in particular to linear farming resistance survey device.
Background
During the soil cultivation process, the cultivation component exerts an acting force on the soil, so that the soil has the effects of cutting, crushing, turning or soil displacement and the like. The soil resistance that the soil exhibits to the tillage member is the soil tillage resistance. In the working process, the farming resistance is fluctuant and random, and the structural shape, the soil condition and the working parameters of the working parts are main factors influencing the farming resistance of the soil. Research shows that the structural shape of the working component has great influence on the soil farming resistance, and the measurement of the soil farming resistance can provide effective help for the design of the component.
The traditional method for measuring tillage resistance mostly adopts a double-tractor method, namely, a rear tractor is hung on a measured farm tool, the rear tractor is pulled by a front tractor to move forward without starting, and a tension meter is hung between the two tractors through a steel wire rope. Two travel measurements were made during the test: the first stroke is idle stroke measurement, the farm tool of the rear tractor is in a transportation state, the second stroke is measurement when the farm tool of the rear tractor works normally, and the tension difference value measured by the two strokes is the traction resistance of the farm tool. The error of the measuring method is very large because the walking resistance of the rear tractor and the resistance of the idle stroke are assumed to be equal when the rear tractor works, but actually the walking resistance and the idle stroke are unequal, because the soil condition is different in two strokes, the rear tractor is subjected to the reaction force of the farm tool when working, the vertical load of the front wheel of the rear tractor is changed, and the acting direction of the traction steel wire rope does not necessarily pass through the gravity center of the rear tractor to generate a certain moment, so the vertical load of the front wheel and the rear wheel is changed, and the larger measuring error is brought.
