The purpose of the present invention is to acquire soil texture information of a land while performing excavation operation on a working site. A hydraulic shovel (1) is provided with a work attachment (20), a drive unit (71), a load sensor (61), a mechanical load calculation unit (503), a soil pressure load calculation unit (504), and a soil texture estimation unit (505). A mechanical load calculation unit (503) calculates a mechanical load, which is the load received by the bucket (23) from the sand, on the basis of the attitude information of the work attachment (20) and information relating to the load received by the drive unit (71). A soil pressure load calculation unit (504) calculates a soil pressure load, which is a load applied to the bucket (23) by a soil block, on the basis of a soil pressure theory, on the basis of the shape of the soil block comprising the soil excavated by the bucket (23), the attitude information, the shape of the bucket (23), the density of the soil, and the wall friction angle between the soil and the bucket (23). A soil texture estimation unit (505) estimates the soil texture of the soil at the work site on the basis of the mechanical load and the soil pressure load.
本发明一边在作业现场进行挖掘作业，一边取得土地的土质信息。液压挖掘机(1)包括作业附属装置(20)、驱动部(71)、负载传感器(61)、机械负荷运算部(503)、土压力负荷运算部(504)及土质估计部(505)。机械负荷运算部(503)根据作业附属装置(20)的姿势信息及与驱动部(71)所承受的负荷相关的信息，运算铲斗(23)从砂土承受的负荷即机械负荷。土压力负荷运算部(504)根据被铲斗(23)挖起的土所构成的土块的形状、所述姿势信息、铲斗(23)的形状、土的密度、土与铲斗(23)之间的壁面摩擦角，基于土压力理论来运算所述土块施加于铲斗(23)的负荷即土压力负荷。土质估计部(505)基于所述机械负荷和所述土压力负荷来估计作业现场的土的土质。
