PROBLEM TO BE SOLVED: To provide a combine in which the yield distribution of a field can be determined more accurately.SOLUTION: A combine includes: a conveying mechanism for conveying the grain obtained in a threshing unit for threshing the grain culm reaped from a field to a grain tank a measuring unit for measuring a grain amount conveyed to the grain tank as the conveyance yield a yield assignment calculation unit for calculating a micro-partition yield being the yield per micro-partition by assigning the conveyance yield to the micro-partition of the field a grain conveyance state detection unit for detecting a grain conveyance state of the conveying mechanism a yield correcting unit for correcting the micro-partition yield according to the grain conveyance state and a yield distribution data generation unit for generating yield distribution data to represent the yield distribution of the field from the micro-partition yield.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】圃場の収量分布がより正確に求められるコンバインの提供。【解決手段】コンバインは、圃場から刈り取った穀稈を脱穀する脱穀部で得られた穀粒を穀粒タンクに搬送する搬送機構と、穀粒タンクに搬送される穀粒の量を搬送収量として計測する計測部と、圃場の微小区画に前記搬送収量を割り当てることで微小区画当たりの収量である微小区画収量を算定する収量割り当て算定部と、搬送機構の穀粒搬送状態を検知する穀粒搬送状態検知部と、穀粒搬送状態に応じて微小区画収量を補正する収量補正部と、微小区画収量から前記圃場の収量分布を表す収量分布データを生成する収量分布データ生成部とを備えている。【選択図】図1
