摘要： PROBLEM TO BE SOLVED: To prevent soil into a slide hole engaged with the operation arm of an expansion blade from being deposited and compacted in an expansion head.
SOLUTION: A hydraulic cylinder is coaxially installed in the head rod of the expansion head for excavating operation, and the expansion blade having the operation arm extended from a blade base part in the opposite direction is pivotally supported on the outer peripheral part of the head rod so as to be expanded and contracted at the blade base part. Also, a slide piece is slidably engaged with a slide hole formed at the end part of a reciprocatingly driven cylinder so as to be passed therethrough in the vertical direction, and the tip part of the operation arm is rotatably connected to the slide piece. When the expansion blade is expanded and contracted by the reciprocating driving of the cylinder, the slide piece is reciprocatingly and slidably moved in the slide hole through the operation arm.

摘要翻译：要解决的问题：为了防止土壤与膨胀叶片的操作臂接合的滑动孔被沉积并压实在膨胀头中。解决方案：液压缸同轴地安装在用于挖掘操作的膨胀头的头杆中，并且具有从叶片基部沿相反方向延伸的操作臂的膨胀叶片枢转地支撑在头杆，以便在叶片基部伸展和收缩。此外，滑动件与形成在往复驱动气缸的端部的滑动孔可滑动地接合，以便在垂直方向上穿过，并且操作臂的前端部可旋转地连接到滑动件。当膨胀叶片通过气缸的往复驱动而膨胀和收缩时，滑块通过操作臂在滑动孔中往复运动并可滑动地移动。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To simplify the joining section of an excavating rod and reduce the size of it by using a cylinder having no spring and a single hydraulic line system.
SOLUTION: A hydraulic cylinder type expansible head has a constitution wherein a hydraulic cylinder is built in a head rod at the bottom end of the excavating rod, the single hydraulic line for feeding a hydraulic fluid into the cylinder from outside is passed longitudinally through the excavating rod and expansible blades to be expanded/contracted by driving the hydraulic cylinder are provided on the outer circumference of the head rod. A piston side space having a piston pressure receiving face for receiving a hydraulic pressure and a rod side space having a piston pressure receiving face having an area smaller than that of the former face are defined within the hydraulic cylinder with interposing the piston between the two spaces. Branch lines branched from the single hydraulic line are connected with the piston side space and the rod side space. The piston is driven to the other side by an external force applied to the expansible blades.

摘要： PROBLEM TO BE SOLVED: To surely collect a sample in a wide viscosity range from low viscosity to high viscosity and at a prescribed depth by a simple configuration.SOLUTION: An opening 16 for collecting a sample is formed on a side face of a collection cylinder 15, and a slide cylinder 7 is slidably inserted into the collection cylinder 6 so as to open/close the opening 16 of the collection cylinder 6. The slidable slide cylinder 7 has a construction in which a lower part in a sample taking side is opened and an upper part in the opposite side to the sample taking side is closed.
摘要翻译：要解决的问题：通过简单的配置，可以从低粘度到高粘度，在规定的深度范围内确保采集样品。解决方案：用于收集样品的开口16形成在收集缸15的侧面上，滑动缸7可滑动地插入收集缸6中，以打开/关闭收集缸的开口16 可滑动的滑动筒7具有这样的结构，其中取样侧的下部被打开并且与取样侧相反的一侧的上部被封闭。版权所有（C）2012，JPO＆INPIT
