Title:
ON-VEHICLE TYPE GENERATING EARTH IMPROVING DEVICE
Document Type and Number:
Japanese Patent JP2769969
Kind Code:
B2
Abstract:
PURPOSE: To use a device for nighttime work in an urban district in a low noise by covering the whole device with a box-shaped load-carrying platform by installing internally a sound absorbing material on the inside surfaces of a side wall and a ceiling wall, covering an engine generator body with a sound absorbing cover, and connecting an exhaust pipe to an underfloor noise eliminator.
CONSTITUTION: Except a through-port 47 of an improved earth carrying-out conveyor 29, the whole device is covered with a box-shaped load-carrying platform 45 by installing internally a sound absorbing material 49 on the inside surfaces of a side wall and a ceiling wall. Next, an exhaust pipe 43 of a generator body is inserted in a through hole bored in a floor of a car body 1, and is connected to a low noise type noise eliminator 44. A noise is dispersed in three directions. Thereby, since the noise generated by a generator 37 and the other device is absorbed by the sound absorbing material and the noise is dispersed in three directions, the noise can be restrained further low.
