JPS6024644Y2 - Protective box cover for combine harvester - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a protective box cover that protects an engine, a radiator, and an oil filler port for oil such as fuel oil or lubricating oil in a combine harvester.

The engine and its radiator in a combine harvester are housed in a protective box to prevent debris such as straw from adhering to it.

During the reaping process, extremely large amounts of small straw and dust fly up into the air and are sucked in through the mesh of the air intake port for the engine provided in the protective box. The radiator is easily clogged, and the clogged state of the radiator inside the protective box cannot be easily identified from the outside.As a result, the engine coolant temperature rises too much and the output decreases. However, there is a problem in that the cause of this problem, the clogging of the radiator, is often not noticed.

Therefore, in this invention, the radiator, which is housed inside the protective box, and the oil or fuel filler port located on the side of the radiator are positioned so that they are both exposed to the outside when the lid of the protective box is opened. With this structure, when the lid is opened to refuel through this refueling port, the radiator is also exposed to the outside, so it is easy to see if the radiator is clogged, and the fins of the radiator must be cleaned every time refueling is performed. The engine was devised so that the engine could be operated and used in normal condition at all times.

The specific structure will be explained based on an example shown in the drawings.The engine 1 is mounted on the center of the fuselage 5 of the combine, and the front surface 2a of the radiator 2 disposed adjacent to the engine 1 is connected to the fuselage 5. Install it inside the protective box 3 facing outward,
The upper surface of the protective box 3 has an opening 3a that communicates with an air intake port 6 having a mesh for cooling air, and a lid 7 is provided on the front surface of the protective box 3 so as to be openable and closable so as to cover the entire front surface.
It is formed so that only clean air from the air intake port 6 passes through the inside of the protective box 3, as shown by the arrow.

On the other hand, an oil supply pipe 8 is extended upwardly from an oil pan 1a attached to the bottom of the engine 1, and the oil supply port 4 provided at the tip of the oil supply pipe 8 is exposed into the protection box 3. A fuel filler port 4 equipped with a horizontal curved gauge is provided adjacent to the radiator 2.

In the figure, reference numeral 9 is an air cleaner that supplies clean air to the engine's carburetor, 10 is a cooling fan provided on the back of the radiator 2, and the fuel filler port 4 is for supplying fuel or lubricating oil. It can be applied to any purpose.

Since this device is configured as described above, when the lid body 7 is opened to refill fuel or oil, the radiator 2 located on the side of the fuel filler port 4 is also exposed to the outside. Since the clogging state of the radiator 2 can be seen, the fins of the radiator 2 can be cleaned without forgetting to do so every time the radiator 2 is refueled.

That is, during reaping work, an extremely large amount of small straw and weeds fly into the air and are easily sucked in through the mesh of the air intake port 6 of the protective box 3 and clog the fins of the radiator 2. As a result, the cooling effect of the engine deteriorates and the output decreases, but since the radiator 2 is housed in the protective box 3, it is difficult for the operator to notice this. In this invention, when refueling with oil or fuel (which is normally done before reaping work), the refueling port 4 is in the same plane as the intake surface (fin) side of the radiator 2, so it is necessary to The clogging condition of the radiator 2 can be noticed at a glance, and there is no need to take the trouble of checking the clogging condition of the radiator 2 separately from the refueling process, making it efficient and allowing the engine to operate in good condition. be effective.
