Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 エンジンの出力特性や圃場条件の差に起因し て頻繁にもしくは必要以上に減速作動するのを防止し て、円滑な速度制御を実行する。 【構成】 この対地作業装置の対地レベルを所定値に維 持する自動昇降制御手段Aを備え、泥硬さセンサ9の検 出結果に応じて前記自動昇降制御手段Aによる制御感度 を変更するよう構成し、設定手段PM4による設定値に かかわらず、エンジン回転数検出手段19の検出値が所 定レベル内に収まるよう前記変速操作用電動アクチュエ ータ20を自動制御する自動減速制御手段Bを設けると ともに、前記泥硬さセンサ9を、その泥硬さ検出値を電 気信号として出力するよう構成し、この泥硬さセンサ9 による検出値に基いて、前記自動減速制御手段Bにおけ る自動変速量を演算する手段Cを備えてある。 (57) [Abstract] [Purpose] Smooth speed control is performed by preventing frequent or unnecessarily slowing down due to differences in engine output characteristics and field conditions. An automatic lifting control means A for maintaining the ground level of this ground work device at a predetermined value is provided, and the control sensitivity of the automatic lifting control means A is changed according to the detection result of the mud hardness sensor 9. The automatic deceleration control means B for automatically controlling the electric actuator 20 for gear shift operation is provided so that the detection value of the engine speed detection means 19 falls within a predetermined level regardless of the value set by the setting means PM4. The hardness sensor 9 is configured to output the detected mud hardness value as an electric signal. Means C for calculating the automatic shift amount in the automatic deceleration control means B is provided based on the detected value by.
