Description

[Detailed description of the invention] This invention relates to an engine cooling structure for a combine harvester that uses the machine frame in the engine room as a water supply pipe.

Conventionally, this type of engine cooling structure has been designed to facilitate cooling water supply and replenishment by arranging the engine water inlet at the outermost part of the engine room to facilitate cooling water supply and replenishment work. Ta.

In this case, it is necessary to mount the engine while taking into consideration the location of the water inlet, and the location of the water inlet is limited, which limits the design and manufacturing of the engine, which affects the price and weight of the engine. There was a drawback that there was a risk of adverse effects.

This proposal was made to solve the above-mentioned drawbacks, and in a combine harvester in which an engine room 2 is formed in the machine frame 1 and an engine 3 is mounted in the engine room 2, the machine frame 4 of the engine room 2 is connected to the water supply pipe. 5, a water supply port 6 is opened in the water supply pipe 5, and a drainage lower which communicates with the water supply port 6 via the water supply pipe 5 is configured to freely communicate with the water intake port 8 of the engine 3. The purpose of the present invention is to facilitate the supply of cooling water, facilitate the design and manufacture of the engine, and thereby make the engine less expensive and lighter.

To explain the embodiment shown in the drawings, A is a self-removal type combine harvester, which is provided with a reaping section 10 at the front of the machine, a foot chain 11 extending from the reaping section 10 to the rear of the machine, and in the center of the machine. A threshing section 12 is provided, a straw processing section 13 is provided at the rear of the machine, and a track traveling device 14 as a traveling device is provided at the bottom of the machine.

Reference numeral 2 denotes an engine room formed outside the rearmost part of the machine base 1, and an engine 3 is mounted in the engine room 2.

At tL, the machine frame 4 of the engine room 2 is configured as a water supply pipe 5.

The water supply pipe 5 comprises a part of the machine frame 4 as a hollow pipe, has a water supply port 6 at the top, and connects a drainage lower which communicates with the water supply port 6 via the water supply pipe 5 to the water receiving port of the engine 3. The facility will be opened in the vicinity of 8.

A flexible pipe 9 is connected to the drainage lower, and the water inlet 15 of the flexible pipe 9 and the water receiving port 8 of the engine 3 are configured to freely communicate with each other, so that the drainage lower and the water receiving port 8 are configured to freely communicate. It is something.

The flexible pipe 9 is preferably made slightly longer than the distance between the drainage lower and the water intake port 8 of the engine 3.

Note that 15 is an exhaust pipe of the engine 3, and 17 is an air cleaner.

Therefore, when supplying or replenishing the engine 3 with cooling water, open the water inlet 8 of the engine 3, insert the water inlet 15 of the flexible pipe 9 into the opened water inlet 8, and connect it to the drain lower. The water inlet 8 is communicated with the water inlet 8, and water is supplied from the water inlet 6 in this state.

At this time, the cooling water injected from the water inlet 6 flows into the water supply pipe 5 as the machine frame 4, flows from the drainage lower through the flexible pipe 9, flows into the water inlet 8 from the water inlet 15, and flows into the interior of the engine 3. water is supplied to the area.

When the water supply is finished, the flexible pipe 9 is removed from the water inlet 8 to disconnect the drainage lower and the water inlet 8, and the water inlet 8 is closed to complete the cooling water supply and replenishment work. .

Since this project is constructed as described above, water supply work can be carried out in a wide area unlike the conventional one, and the work can be carried out easily.
When mounting the engine 3 on the tower, it is not necessary to arrange the water inlet 8 at the outermost part, and the position of the water inlet 8 is not limited, so the design and manufacture of the engine 3 are facilitated.
This has the effect of making it possible to reduce the price and weight of the product.
