The utility model discloses a crop measuring device that resists lodging, which comprises a frame, be provided with measurement element in the frame, measurement element includes power device, connectthe rope, connect rope guiding mechanism, the stem stalk presss from both sides, and measuring transducer, but the stem stalk presss from both sides the centre gripping to be fixed on the stem of plant stalk, the both ends of connecting the rope link to each other with stem stalk clamp and power device respectively, power device is through connecting the rope to stem of plant stalk output pullingforce with stretch bending stem of plant stalk, the stretch bending angle of measuring transducer measurable quantity stem stalk, pulling force angle and pulling force value on the stem stalk act on,thereby resist lodging to the crop and measure. The utility model discloses a crop measuring device that resists lodging can realize utilizing force sensor to detect the pulling force that the stem of plant stalk received to can pass through the data processing display element real -time supervision record, crop measuring device that resists lodging can adopt servo motor to replace artifical pulling, through the angle of control motor pivoted number of turns control stem of plant stalk stretch bending, realization precision measurement.
