Vehicle-mounted soil conicity index detection device and tractor

The utility model provides a vehicle-mounted soil cone index detection device and a tractor. The device comprises a non-return device, a support, a swing arm, a pressure sensor, an angle sensor and acontrol system, a rotating shaft at one end of the swing arm is supported in the support through a bearing, the pressure sensor is installed at the other end of the swing arm, and the pressure sensoris used for measuring the resistance value of soil in the accelerated penetration process; a non-return device is mounted on the rotating shaft at one end of the swing arm and used for preventing theswing arm from descending due to gravity; the angle sensor is used for detecting the rotation angle of the swing arm; and the control system outputs a soil cone index according to detection values ofthe pressure sensor and the angle sensor. The pressure sensor can penetrate into soil through rotation of the rotary arm, the measured pressure value measured by the pressure sensor and the angle sensor measure the rotation angl
