It provides a means to accurately measure the quantity of water in a packaging accompanying cutting work. In the input section 16, the rotating blade 27 that scrapes the grain conveyed by the grain-feeding device and inserts it into the inside of the grain-tank is brought into contact with the grain inputted by the rotary blade 27 to be introduced by the grain-feeding device. An input amount measurement sensor 22 for measuring the amount of grain input is provided. The input amount measurement sensor 22 is provided with a load cell 40 that receives a force from a grain input by the rotating blade 27 and deforms in a direction crossing in the vertical direction, and a receiving member 39 in contact with the grain. One of the upper end and the lower end of the load cell 40 is fixed to the grain tank, and the receiving member 39 is provided on the other of the upper end and the lower end of the load cell 40. In addition, in the configuration for measuring the quantity of water in the packaging accompanying the harvesting operation, the bias of the grain input to the grain tank is suppressed. The combine includes a threshing device for threshing the cropped grain, a grain tank for storing grains obtained by the threshing device, a grain device for conveying the grains sent from the threshing device upward, and putting them inside the grain tank, and a grain device. A guide member 21 for regulating the throwing direction of the grains to be inputted is provided, and an input amount measurement sensor 22 for measuring the input amount of grains input by the grain device by contacting the grains input by the grain device. The upper end of the grain receiving surface 39a in the input amount measurement sensor 22 is located above the upper end of the grain guiding surface 21c in the guide member 21, and the grain guiding surface 21c in the guide member 21 ) And the normal direction of the grain receiving surface 39a in the input amount measurement sensor 22 are different.예취
