Embodiment Construction

[0029] Before describing the specific embodiment of the combine harvester of the present invention, use figure 1 The basic principles characterizing the present invention will be described.

[0030] exist figure 1 In the example of , the combine harvester 1 harvests the grain stalks of wheat and rice while traveling in the field, and the detached grains are stored in the grain tank 15 mounted on the combine harvester 1 . At this time, in this combine harvester 1, the quantity of the grain supplied to the grain tank 15 with the lapse of time, that is, the yield is measured. Furthermore, the food taste (moisture content, protein, etc.) of this grain can also be measured.

[0031]In order to measure the yield of grains, a yield measuring container 32 is provided on the grain tank 15, and the yield measuring container 32 has a yield receiving port 32a for receiving at least a part of the grains supplied to the grain tank, and an outlet for discharging. The yield discharge por...

Abstract

A combine comprises: a yield measurement container (32) provided with a yield receiving opening (32a) for receiving at least some of the grains supplied to a grain tank (15) for accumulating grains obtained by threshing, the yield measurement container (32) being also provided with a yield discharge opening (32b) for discharging received grains, the yield measurement container (32) being further provided with a yield shutter (34) for opening and closing the yield discharge opening (32b); a yield measurement section for detecting, while the yield shutter (34) is closed, that a predetermined volume of grains has been accumulated in the yield measurement container (32) and outputting a detection signal; a time calculation section for calculating, on the basis of the detection signal, accumulating time required to accumulate the predetermined volume of grains; and yield calculation section for calculating a yield per unit travel on the basis of travel speed and the accumulating time.

Description

technical field [0001] The present invention relates to a combine harvester that reaps grain stalks from a field while traveling, threshes the harvested grain stalks, and stores the obtained grains in a grain box. Background technique [0002] There has been proposed a combine harvester which measures the weight and water content of grains stored in a grain box, and outputs them as harvest information of harvested grains. For example, the combine harvester of patent document 1 is equipped with the moisture measuring device which takes in some of the grains supplied to a grain tank, and measures the moisture content, and the load cell which detects the load of a grain tank. During the harvesting travel of the combine harvester, the harvested area is calculated from the travel speed, travel time, and harvest width and the increase in grain weight per the harvested area is calculated, and this process is repeated to output the harvested area unit of the field. volume distribut...
