To provide an electro-hydraulic bucket including a variable capacity pump, which can detect the completion of opening/closing of a bucket based on a current value without using a pressure switch and perform driving control of the bucket, as well as to provide a control device thereof, and a control method thereof.SOLUTION: An electro-hydraulic bucket includes a bucket main body, a hydraulic unit performing opening/closing operation of the bucket main body, and a control part for controlling driving of the hydraulic unit. The control part acquires current data supplied to the hydraulic unit, performs comparison operation of the acquired current data and a predetermined value, and outputs a signal relating to the driving of the hydraulic unit based on an operation result. A control device and a control method of the electro-hydraulic bucket are also provided. Accordingly, the completion of opening/closing of the bucket main body can be detected based on the current data without detecting the pressure of hydraulic oil by using a pressure switch and the driving control can be performed based on a detection result.SELECTED DRAWING: Figure 1

    【課題】本発明の課題は、可変容量ポンプを備えた電動油圧式バケットにおいて、圧力スイッチによらず、バケットの開閉完了時を電流値に基づき検出し、バケットの運転制御を行うことができる電動油圧式バケットと、その制御装置及び制御方法を提供することである。【解決手段】上記課題を解決するために、バケット本体と、バケット本体の開閉操作を行う油圧ユニットと、油圧ユニットの駆動を制御する制御部とを備え、制御部は、油圧ユニットに供給される電流データを取得し、得られた電流データと所定値との比較演算を行い、演算結果に基づき、油圧ユニットの駆動に係る信号を出力することを特徴とする電動油圧式バケットと、その制御装置及び制御方法を提供する。これにより、圧力スイッチを用いた作動油の圧力検出によらず、電流データに基づきバケット本体の開閉完了時を検出し、その検出結果に基づく運転制御を行うことが可能となる。【選択図】図1
