Problems solved by technology

[0004] For ordinary rice transplanters, the high-speed position of the accelerator lever (accelerator) of the engine speed is changed during operation, and the speed of the vehicle is changed by operating the shift operating lever for shifting. However, when adding seedlings, even if the shift operating lever is operated to the neutral position To stop the body, as long as the accelerator lever does not return to the low speed position from high speed, the engine speed will remain at high speed and quieter work cannot be performed
In addition, when the engine speed is low under the high speed state of the continuously variable transmission mechanism, there is a possibility that the output may become insufficient, or when the continuously variable transmission mechanism and the engine speed are both high and the clutch is engaged, there is a danger that the body will suddenly start

Abstract

The present invention provides a working vehicle such as a rice transplanter that uses the output of the engine to drive a transmission that changes the working speed such as the vehicle speed. Drive to perform good work, wherein, there is a transmission (48) that is driven by the output of the engine (2) to change the working speed, and the work that performs the speed change operation on the transmission (48) is changed through the connecting member (88) The operating member (30) is interlinked with the engine rotation changing member (87) for changing the engine speed.

Description

[0001] The patent application of the present invention is a divisional application of the invention patent application with the application date being December 19, 2003, the application number being 200380104007.8, and the invention name being "working vehicle". technical field [0002] This invention relates to work vehicles, such as a rice transplanter, a tractor, or a combine, which has a seedling loading platform and a seedling planting claw, and performs a seedling planting operation continuously, for example. Background technique [0003] In the prior art, there is a technique of using a hydraulic continuously variable transmission mechanism (HST) composed of a variable-capacity hydraulic pump and a hydraulic motor as the travel transmission device of the rice transplanter. The angle of the swash plate of the speed change mechanism is changed. (eg, Japanese Patent No. 2979580) [0004] For ordinary rice transplanters, the high-speed position of the accelerator lever (...
