Embodiment Construction

[0097] In embodiment of this invention, the riding-type rice transplanter of a six-row planting type is shown as an example of the work vehicle which performs rice transplanting work in a field (paddy field).

[0098] Unless otherwise specified, the front-rear direction and the left-right direction in the embodiment of the present invention are described as follows. When the traveling body 50 travels, the traveling direction of the forward side is "front", and the traveling direction of the backward side is "rear". Based on the forward-facing posture in the front-rear direction, the direction corresponding to the right side is "right", and the direction corresponding to the left side is "left".

Abstract

In a work vehicle where operation travel and turning are performed repeatedly, the burden of a driver can be reduced. The work vehicle includes a positioning unit (30) that detects the position of a traveling body (50), a work travel route acquiring unit that acquires work travel routes (L01, L02), and a turning route acquisition unit that acquires a turning route (LL1) connecting an end of the work travel rout (L01) and an end of the next work travel route (L02). An automatic travel control unit is automatically operated based on the position of the traveling body (50) to drive the travelingbody (50) to travel along the work travel routes (L01, L02). An automatic turning control unit is automatically operated based on the position of the traveling body (50) to drive the traveling body (50) to travel along the turning route (LL1). A control unit that switches between a work mode in which the automatic travel control unit operates and a turning mode in which the automatic turning control unit operates, is provided.

Description

technical field [0001] The present invention relates to a working vehicle for working in fields. Background technique [0002] In a passenger-type rice transplanter as an example of a work vehicle that works in the field, as disclosed in Patent Document 1, in the field, it travels approximately straight from one field ridge to the other field ridge, and performs transplanting of seedlings using a rice transplanting device. Transplanting rice seedlings, or using a fertilizer applicator to supply fertilizer to the field and other operations. Next, when the traveling body reaches the other ridge, the work travel is stopped and the other ridge boundary is turned around, the next work travel is started from the other ridge to the one ridge, and the work travel and turning are repeated. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2010-207119 (refer to Figure 6 ) [0004] As described above, there is room for improvement in lightening the burden on the...
