Abstract

PURPOSE:To effectively remove dust from cooling air and also to make a cooling/dustproof device free from maintenance by arranging a cyclon-type dust collector outside of a cooling air inlet opened on a bonnet on the opposite side of a radiator core. CONSTITUTION:A cyclon-type dust collector 13 is arranged outside wall 11 opposite to a radiator core 10. Then, the outer air inlet 19 of the cyclon-type dust collector 13 is formed on the side near a radiator 7, and a clean air outlet 20 is formed on the side far from the radiator 7. Additionally, below the peripheral face of the external case 16 of the cyclon-type dust collector 13, a dust exhaust outlet 21 is opened. Consequently, cooling air for an engine 6 is drawn in a bonnet 8 through the cyclon-type dust collector 13, but the dust flowing into the cyclon-type dust collector 13 being carried on the cooling air is collected on the inner peripheral surface side of the external case 16 by its power of inertia while passing, and then automatically discharged outside through the dust exhaust outlet 21.

The outside air intake (19) of the cyclone type dust remover (13) is connected to the bonnet side end of the outer case (16), and the incoming air is tangentially connected between the inner circumferential wall of the outer case (16) and the inner cylinder (17). The floating outlet (20) is formed at the bottom wall side end of the circumferential wall of the inner cylinder (17). In addition, a dust outlet (21
) is formed in such a way that the swirling airflow can flow out smoothly, as shown in FIG. Therefore, the outer case (16
) The outside air that has flowed in between the inner circumferential wall of the outer case (16) and the inner cylinder (17) flows spirally through the space between the inner circumferential wall of the outer case (16) and the inner cylinder (17), and flows through the floating air outlet (2o). During this spiral flow, the dust absorbed in the outside air is collected on the inner circumferential surface of the lid of the outer case (16) due to inertial force. This collected dust is discharged from the dust outlet (21) formed in the outer case (16) to the outer case (16).

) into the circular case (28), and the circular case (2
8), an outside air intake (19) is opened in the side wall (29) on the bonnet (8) side to form a cyclone type dust remover (13). (28) The opening edge is bent diagonally inward so as to form a spiral flow within the opening. Further, a dust outlet (21) is provided at the end of the bonnet (8) side of the lower part of the circumferential wall (30) of the circular case (28).

(Effects) In the present invention, the cyclone dust remover is placed outside the cooling air intake opening in the bonnet facing the radiator core, and the outside air intake of the cyclone dust remover is formed on the side closer to the radiator. At the same time, the floating outlet of the cyclone dust remover is formed on the side far from the radiator, and the dust outlet is opened at the bottom of the circumferential surface of the cyclone dust remover's exterior case, so the engine cooling air is passed through the cyclone dust remover. The dust that flows into the cyclone type dust remover on the cooling air is collected on the inner circumferential side of the outer case due to its inertia while passing through the cyclone type dust remover, and the dust is drawn into the hood through the cooling air. The dust is automatically discharged to the outside from the dust outlet formed at the bottom of the peripheral surface. As a result, dust can be efficiently removed from the cooling air taken into the bonnet, and the removed dust is automatically discharged to the outside of the dust remover, making the dust remover maintenance-free.

In addition, since the cooling air intake facing the radiator and evaporator core surfaces is covered with a cyclone-type dust remover, the radiator core is no longer directly visible outside the bonnet, so the radiator fins are used to remove the radiator air. Sound and engine combustion noise do not leak directly to the outside, making it possible to reduce noise as a working machine.
