動構造を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a driving structure for a working vehicle in which cooling air flows smoothly from the radiator to the engine without flowing backwards.
次に、本考案の実施例を図面に基づいて説明す

ように構成してある。 In the driving unit C, as shown in FIGS. 2 and 3, an engine cooling radiator 4 is installed inside the engine bonnet 2 and facing the engine 3.
between the engine 3 and the radiator 4,
An engine cooling fan 5 linked to the engine 3 is disposed so that air sucked into the bonnet 2 from an intake port 7 is discharged from an exhaust port 8. Then, backflow prevention plates 9 are installed on both lateral sides of the radiator 4 so as to extend toward the engine 3 side, and the tips 10 of the backflow prevention plates 9 are spaced apart from each other at a constant distance l 2 toward the outside of the engine 3. It is arranged to extend a certain distance l1 from the position of the fan 5 to the engine 3 side, so that even if the cooling air from the fan 5 hits the engine front wall 13, it does not flow back upstream from the lateral outside of the radiator 4, and smoothly. The air outside the backflow prevention plate 9 is also drawn by the attractive force of the cooling air flowing downstream from between the backflow prevention plate 9 and the engine 3. As a whole, the structure is such that a smooth flow is created within the prime mover chamber 6.

も有効である。 Incidentally, as shown in FIG. 4, the backflow prevention plate 9 may be configured to protrude linearly from both ends of the radiator 4 toward the engine 3 at a certain angle of expansion; It may be curved slightly inward to protrude from the radiator 4 in a curved manner.The point is to smoothly guide the cooling air downstream of the fan 5 without obstructing the flow of cooling air formed by the fan 5. It is only necessary to set the shape and size of the backflow prevention plate 9 as much as possible. If necessary, the upper plate 1 may also be placed at a certain upward or downward angle at the upper and lower parts of the radiator 4, as shown by the imaginary lines in FIG.
It is also effective to make the lower plate 1 or the lower plate 12 protrude toward the engine 3 side.

設定して配置してあることを特徴構成とする。 In summary, the present invention, in the drive unit structure of the above-mentioned working vehicle, has one end connected to each of both lateral sides of the radiator 4, and the other end extending toward the engine 3 side. A pair of left and right backflow prevention plates 9 is provided, and the other extended end of the backflow prevention plates 9 is located in a direction intersecting the cooling air that has passed through the radiator 4 and on the lateral outside in the width direction of the engine 3. The extended length and position of the cooling fan 5 are set so as to be located further away from the end and closer to the engine 3 than the installation position of the cooling fan 5. shall be.

になつた。 That is, with the above characteristic configuration, the cooling fan 5
Even if the cooling air collides with the engine 3, the cooling air that tries to flow back hits the backflow prevention plate 9 and is prevented from flowing back, and is then pushed by the cooling air that comes from behind and flows backwards into the engine 3. Since the cooling air passes between the side and the backflow prevention plate 9, the backflow prevention plate prevents the cooling air from flowing back from the side outside of the radiator 4 to the upstream side due to collision with the engine 3. 9 can be effectively prevented, and as a result, overheating of the radiator 4 and engine 3 can be sufficiently prevented, and troubles caused by overheating of electrical components installed in the vicinity can now be sufficiently prevented. .
