Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an engine cooling device that sends and circulates cooling water for cooling an engine to a radiator, thereby cooling the engine with air.

According to the present invention, the side plate of the adjacent paddy tank is extended to cover the outside of the engine cooling device provided at the upper part of the engine, and the cooling air intake port of the cooling device is provided in the side plate. To provide an engine cooling device for a combine harvester, which aims to improve the mutual strength of the engine part and the paddy tank, and also provides a sense of unity between the engine part and the tank, and which has a simple structure, is compact, and has an excellent engine cooling effect. This is what I am trying to do.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings. Figure 1 is a schematic side view of the combine harvester, Figure 2 is a plan view of the same, and in the figure 1 is a truck frame;
2 is a traveling crawler, 3 is a machine base, 4 is a rotation fulcrum shaft 5
a hydraulic cylinder that raises and lowers the machine platform 3 around the
6 is a threshing unit with a built-in handling cylinder 6a, and 7 is a cutting blade 8.
9 is a grain culm conveyance unit, 10 is a straw removal processing unit with a built-in straw cutter, 11 is a feed chain, and 12 is an exhaust system that transports the grain culm inherited from the feed chain 11 to the straw removal processing unit 10. A straw chain 13 is a paddy tank into which the grains taken out from the first opening 14 of the threshing section 6 are fed via a grain frying conveyor 15, 16 is a driver's seat provided in the driver's cab 17 at the front right of the machine, and 18 is a A driving operation section provided in front of the driver's seat 16; 19 indicates the driver's seat 16 and the paddy tank 13;
20 is a paddy receiving stand provided below the paddy tank 13, and 21 is a paddy bag filled with grains discharged from the paddy discharge port 23 of the paddy tank 13 suspended from the support arm 22. The grain culms continuously harvested by the reaping section 7 are transferred to the threshing section 6 by the grain culm conveying section 9 and the feed chain 11 for threshing, and the grains taken out from the first opening 14 are transferred to the grain frying conveyor 15. The paddy is stored in the paddy tank 13 through the paddy tank 13 and taken out from the paddy discharge port 23 into the paddy bag 21 as appropriate.

As shown in FIG.
6, the engine 27 and fuel tank 28 are placed in the lower chamber 25, and the radiator 2, which is a cooling device, is placed in the lower chamber 25.
9 and a cooling fan 30 are arranged in the upper chamber 26, respectively. The engine 27 is provided with an output pulley 31 that drives each part of the combine, and the engine 27 and the radiator 29 are communicated with each other through cooling water pipes 32 and 33.
4. They are connected together via a V-belt 35 and a pulley 36 to drive each drive section of the combine as well as the engine cooling device, that is, the cooling fan 30.

Furthermore, a radiator dustproof device 39 formed of a double lid structure consisting of a main body cover 37 and a filter cover 38 is attached to the intake side of the cooling air from the cooling fan 30. The main body cover 37 is an inlet cover 40
and a radiator side plate 41a which is integrally extended with the side plate 41 of the adjacent paddy tank 13 as shown in FIG. At the same time, a cooling air intake port 43 is formed in the side plate 41a. The filter cover 38 includes a dustproof screen 44, and a hinge 45 and a locking member 46 so that the screen 44 can open and close the suction port 43.
A filter cover 38 is attached to the side plate 41a via the filter cover 38, and a dustproof filter 47 is interposed between the filter cover 38 and the side plate 41a.
Cooling air is introduced from the suction port 43 through a dustproof net 44 and a filter 47.
By making it possible to attach a filter 47 to the entire area of the suction port 43, the suction speed of the cooling air is lowered to reduce the dust suction rate, and the filter cover 38 is opened with a single touch, allowing the filter 47 to be installed in the entire area of the suction port 43.
By making it possible to attach or remove the filter 47, it is easier to replace or clean the filter 47, and by making the body cover 37 box-shaped, the rigidity of this part is improved, making it robust and excellent in dust removal ability. The dustproof device 39 is connected to the cooling device, that is, the cooling fan 3.
It is configured to be installed on the suction side of 0.

As mentioned above, as is clear from the embodiments, the present invention provides an engine cooling device 2 provided at the upper part of the engine 27.
The side plates 41, 41a of the adjacent paddy tank 13 are extended to cover the outer sides of the 9, 30, and the side plates 41a
Since the cooling air intake ports 43 of the cooling devices 29 and 30 are opened at the front, the mutual strength of the engine 27 section and the paddy tank 13 can be improved, and the engine 27 section and the tank 1
3 has a sense of unity, the structure is extremely simple and compact, and it has remarkable effects such as excellent engine cooling effect.
