The invention discloses a pivot-pin force sensor, an agricultural machinery suspension device using the pivot-pin force sensor and a soil resistance measurement method. A detection unit is arranged on the pin body of the pivot-pin force sensor, and the sensing chip of the detection unit includes The X-direction sensing chip and the Y-direction sensing chip are perpendicular to each other; the agricultural machinery suspension device includes a pull-up rod, a pull-down rod, a lift rod, and a lift arm. Or the rear end of the pull-up rod is hinged with the agricultural machinery through the pin-type force sensor; the soil resistance measurement method of the present invention calibrates the pin-type force sensor before application, and writes the MAP diagram into the electronic control unit. During actual operation, According to the measured Mx and My values, by querying the MAP diagram, the soil resistance can be quickly obtained, which is convenient for controlling the depth of agricultural machinery in the soil, and can meet the needs of various soil depth operations, and the measurement of soil resistance is accurate and convenient.
Description
technical field [0001] The invention relates to the technical field of force measurement, in particular to a pivot-pin force sensor capable of measuring multi-directional forces, an agricultural machinery suspension using the pivot-pin force sensor, and a soil resistance measurement method for the agricultural machinery suspension. Background technique [0002] At present, the traditional pin type force sensor 1' on the market has a structure such as Figure 1 to Figure 4 As shown, in the length direction of the shaft pin body, two induction chips are installed at intervals, that is, two X-direction induction chips 12X with the same installation direction, the shaft pin is subjected to a force F in the X direction (F=F1+F2), and the shaft pin The body is slightly deformed, and the two sensing chips respectively sense the deformation of the shaft pin body, and after processing by the control unit, the value of the force is output. This sensor has a simple structure and has be...
