专利汇可以提供Controller for soil pusher of bulldozer专利检索,专利查询,专利分析的服务。并且PURPOSE:To raise the efficiency of soil pushing operation by a method in which a detector to detect the change in the position of a soil pusher is related to a control mechanism for elevating movement and the soil pusher is vertically moved in the direction of cancelling variations in loads on the soil pusher. CONSTITUTION:A detection signal from a sensor 22 to detect the relative positions between a soil discharge plate 11 and an oil-pressure cylinder 12 is converted into an electric signal by a converter 25 and then compared with the output signal of a target value 27 previously put in a setter 26 in a comparator 28. If the measured value is larger beyond a certain value than the target value, the switching valve 17 is switched to the first offset position (a), the soil discharge plate 11 is brought down to a datum level 24. In the reverse case, the valve 17 is switched to the second offset position (c), the plate 11 is raised up to the reference level 24. Land grading operation can thus be performed nearly uniformly on the basis of the reference level 24.,下面是Controller for soil pusher of bulldozer专利的具体信息内容。
