Embodiment Construction

[0083] for the manner in which the invention is carried out

[0084] (The structure of the rice transplanter)

[0085] First, the overall structure of the rice transplanter 1 which concerns on one Embodiment of this invention is demonstrated. In addition, in this embodiment, although the rice transplanter was made into the rice transplanter of eight-row planting, it is not specifically limited, For example, the rice transplanter of six-row planting, ten-row planting may be sufficient.

[0086] Such as figure 1 and figure 2 As shown, the rice transplanter 1 has a running part 10 and a planting part 40, and is configured so that seedlings can be planted in a field by the planting part 40 while running on the running part 10. The planting unit 40 is arranged at the rear of the running unit 10 , and is connected to the rear of the running unit 10 so as to be able to move up and down via the elevating mechanism 30 .

[0087] In the undercarriage 10 , an engine 14 is provided o...

Abstract

A rice planting machine comprises: an actuator for changing the speed of the engine and / or the transmission ratio of the HST; a speed change means serving as the operation device for changing the amount of drive of the actuator; a control device connected to both the actuator and the speed change means and changing the speed of the vehicle by changing either the speed of the engine and / or the transmission ratio of the HST by means of the actuator on the basis of the amount of operation of the speed change means; and a maximum speed setting means connected to the control device and serving as the operation device for changing the maximum speed which is the speed of the vehicle when the speed change means is operated the maximum amount.

Description

technical field [0001] The present invention relates to the technology of rice transplanter. Background technique [0002] Conventionally, the technique of changing the vehicle speed is well-known about a rice transplanter (for example, patent document 1). [0003] In conventional rice transplanters, the target vehicle speed is usually constant with respect to the amount of depression of the shift pedal as a shift operation tool for forward and reverse. [0004] However, in the case of loading and unloading the rice transplanter on the truck, when the rice transplanter is going in and out of the field, etc., when the rice transplanter is traveling at a low speed, in the conventional rice transplanter, a small amount of control of the speed change pedal is required. Accordingly, it is difficult to run the rice transplanter at a desired vehicle speed according to the field. [0005] prior art literature [0006] patent documents [0007] Patent Document 1: Japanese Patent ...
