专利汇可以提供Controller for performance of bulldozer专利检索,专利查询,专利分析的服务。并且PURPOSE: To control the level of finished face with high accuracy by providing a position measuring controller to obtain performance data by receiving signals from a level sensor and a soil discharge plate controller to send out commands to an oil-pressure actuator operating a soil discharge plate.
CONSTITUTION: When projectors A and B are turned, laser beams from the projectors A and B are received by a reference light receiver S, and the turning period is measured by a monitor 10 and scored in a position-measuring controller 6. After the laser beams from the projectors A and B are received by a light receiver S, the time until received by the light receivers P
1 and P
2 of a bulldozer W is stored in the controller 6. From the distance L between the projectors A and B, the angle between the projectors A and B and the light receiver S, period and time, the angle and coordinate of the receivers P
1 and P
2 are calculated by the controller 6. The position of the bulldozer W in relation to the projectors A and B is calculated by the controller 6 and the performance data are obtained by conversional calculation, The soil discharge plate 2 is controlled by the soil discharge plate controller 4 through an oil-pressure valve actuator 7 with the oil-pressure cylinder on the basis of the data.
