Title:
WEIGHT-DISPLAYING APPARATUS FOR MOBILE WORKING MACHINE
Document Type and Number:
Japanese Patent JP3203376
Kind Code:
B2
Abstract:
PURPOSE: To measure the grain weight in a grain tank utilizing a structure to support a crawler on a machine body via a hydraulic cylinder in a freely liftable state and inform an operator of the measured data.
CONSTITUTION: The objective apparatus is provided with a detector 4 to detect the inner pressure of a hydraulic cylinder 2 in the pressurizing chamber, an arithmetic device 5 having a pretreating operation means 51 to eliminate the fluctuation caused by the ground shock from the detected value by integral operation, a memory 52 and a main operation means 53 to calculate the loaded weight from the detected value in empty state and the detected value in loaded state and a displaying device 6 having a display 61 to display the loaded weight, a power switch 62 and a reset switch 63 to reset the arithmetic device 5 and clear the display 61. The operator can monitor the loaded weight to prevent the undesirable influence on the running performance caused by the overweight.
