As shown in FIG. 3, the aforementioned partition wall 17 shields noise from the engine compartment 4, prevents fire from occurring in the engine compartment 4, and implements a function of improving the appearance of the engine and the pump. It is installed across the connection.

As shown in FIG. 4, the aforementioned partition wall 17 has a first opening in a vertical direction in which an opening 18a formed to pass through a connection portion between an engine and a pump and a through hole 18b through which a hydraulic hose or the like passes are formed. The shielding plate 18 and the second shielding plate 19 are inclinedly connected to the upper end of the first shielding plate 18.

At this time, the partition wall 17 formed of the first shielding plate 18 and the second shielding plate 19 described above has 5-6 single components due to many hydraulic hoses, wires, filters, etc. for connecting a circuit such as a pump and a valve. After cutting into pieces, these pieces are assembled in an assembly line to form a partition wall 17.

As a result, when designing the aforementioned partition wall 17, a lot of unexpected space (referred to as a gap) is generated, and thus the work efficiency decreases due to an increase in working time for assembling the partition wall 17 made of a single piece, and also through the space. Since noise is discharged, there is a problem in that the function of shielding the noise from the engine compartment 4 cannot be smoothly performed.

According to the embodiment of the present invention, as the integral shielding block is mounted at the boundary between the engine chamber and the pump chamber of the excavator, the sound absorbing and shielding function is satisfied by increasing the thickness of the shielding block, and the mutually close adhesion between the shielding block and the adjacent parts having elastic force is increased. Due to this, it is related to an excavator equipped with an integrated shielding block for sound absorption and shielding at the engine compartment boundary, which reduces noise emission through the gap and improves assembly.
