摘要： PURPOSE:To improve cleaning effect by constructing the intake air surface of a dustproof cover for covering a radiator in such a way as to be changeable between the outer enlarged position and the inner enclosed position as well as fitting cleaning fans in such a way as to advance/recede integrally with this intake air surface. CONSTITUTION:A dustproof cover 8 for covering a radiator 7 for cooling an engine E is provided in line with the outer end of an engine bonnet 13. In this case, the intake air surface 8a of the dustproof cover 8 is changeably formed in such a way that its auxiliary intake air surface 8b advances/recedes between the outer enlarged position and the inner enclosed position. For instance, the intake air surface 8a is oscillatingly and axially supported at a lateral axis Y at the lower end part and provided with a holeless side face part 8c formed of fan-shaped bellows. In addition, plural cleaning fans 10, adhesive to the intake air surface 8a, for blowing the dust off outside by the head wind are fitted on the inner face side of the intake air surface 8a through a frame 11a and thus advance/recede integrally with the intake air surface 8a.

摘要： PURPOSE:To obtain a crowler running device which can correspond to running forms of every kind and is comparatively simple in structure and low-priced by providing a space control device for expanding the space between slied members, interlocking with the rise of a truck frame and reducing same, interlocking with lowering of the truck frame. CONSTITUTION:In case of running in a wet field where a truck frame 9 is frequently lowered to a machine frame 6, the grounding surface of a crowler belt 12 is put in the state of completely standing firm by the mutual approach of the slied members 20 to increase a sinking preventing effect. At the time of unloading a load-carrying platform or getting over a ridge between rice fields, the truck frame 9 is lifted up to the machine frame 6, so that the center of gravity is lowered to work safely and the longitudinal space S between the slied members 20 is widened to provide the space S in the longitudinal intermediate part of the grounding length of the belt 12. Accordingly, the center of gravity can be smoothly moved so as to gently restrain a seesaw phenomenon as much as possible, so that uneasy feeling to a driver can be reduced to the utmost.

摘要： PURPOSE:To make is possible to prevent an engine from over-heating even during dust being blown off from a dust-free air sucking means, by locating an auxiliary dust-free air sucking section of the dust-free air sucking means at an external position where dust can hardly be sucked into. CONSTITUTION:A dust-free air sucking means 6 having a main dust-free air sucking section 8 and an auxiliary dust-free air sucking section 9 is disposed on the sucking side of a cooling fan 1 for cooling an engine E. In this arrangement, the auxiliary dust-free air sucking section 9 is located at a position which is outside of the main dust-free air sucking section 8 and at which dust can hardly be sucked, and a dust blowing-off means 11 is arranged being faced to the main dust-free air sucking section 8. In this arrangement, during blowing-off operation of an electrical motor 14, blowing- off air 13 is blown through the main dust-free air sucking section 8 from the inside to the outside thereof so as to blow off dust 7 sticking to the outside of the main dust-free air sucking section 8. During the blowing-off process of this dust 7, the cooling fan 1 continuously rotates in a normal direction so as to suck a large volume of the outside air through the auxiliary dust-free air sucking section 9 to which only a slight quantity of dust sticks, and accordingly the engine E is cooled continuously, thereby it is possible to prevent the engine E from overheating.

摘要： 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.
