Description

[Detailed Description of the Invention] The present invention relates to a front structure of an engine cover in a combine harvester.

That is, in a combine that is configured such that a threshing section is installed behind the reaping section, an engine is installed on the front side of the threshing section, and power is transmitted from the engine to a transmission section on the lower front side of the threshing section by a belt. The engine cooling air flows smoothly, preventing a rise in temperature on the engine side, and the belt transmission part from the engine can be covered to create a safe structure, and the belt transmission part can be protected from the outside. The present invention is provided so that it can be easily confirmed and inspected, and has a simple structure so that it can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a plan view of the combine harvester. At the front left side of the machine body supported by crawlers 4, there is a grass dividing plate 5.5, a lifting case 6, a raking wheel 1, a cutting blade, a conveyor, and a vertical conveyor cheno. 8
A reaping section A is installed, which is equipped with a reaping section A, and behind the reaping section A, along the left side of the machine, a threshing section B is installed, which is equipped with an inlet side supply plate 9, a handling cylinder 10, a foot chain 11, etc. Then, the ear guide plate 12 is extended from the rear of the right-side lifting case 6 to above the supply plate 9, and is connected to the crawler 4 and each part of the reaping section A from the mission case 13 and the reaping transmission section below the supply plate 9. It is constructed in the same way as the conventional structure so as to transmit power.

Further, a cutter 14 is installed at the rear of the threshing section B, an engine E is installed at the front right side of the threshing section B, and a paddy holder 15 and a paddy holder 16 are installed at the rear of the engine E. A rice receiving section consisting of a discharge tube 11 is installed, and a control section 19 consisting of operating levers 18° and 18.18 is installed at the rear of the machine.
Install and configure.

The engine E has a cylinder part 20 on the front side of the fuselage, a starting rope handle 21a protruding outwards and a coil starter 21 installed on the outside of the cylinder part 20, and a cylinder part 20 on the rear side of the cylinder part 20. A cab 22 and an air cleaner 23 are installed, and a muffler 24 is installed on the outside of the cab 22. An engine pulley 26 is disposed at the engine pulley 26, and the belt 1, which is wound around the engine pulley 26, is extended to the front side of the machine body, and the front peripheral end of the belt 1 is connected to the transmission case 13 and the input pulley 21 of the reaping transmission section. A heat insulating plate 28 is hung around and interposed between the cab 22 and the cylinder part 20 and extends to the vicinity of the side wall portion 25.

In addition, a cover 2 is attached to the engine E, and a cover 2 is installed so that cooling air can be taken in from an opening (not shown) formed on the outside of the cover 2 on the side of the recoil starter 21. The front part of the cover 3 made of perforated iron plate extending forward from the inner front part of the case 6 is pulled up on the right side and extended to the rear side of the case 6, and the upper part 3a of the cover 3 is extended to the lower side of the tip guide plate 12. The cover 3 covers the belt 1 from the outside, and the inside of the cover 3 communicates with the cooling air discharge side of the engine cover 2 to correspond to and communicate with the lower side of the supply plate 9. The installation is configured as follows.

Therefore, the engine E can be covered with the cover 2, and the belt 1 that transmits power to the running section and the reaping section A can be covered with the cover 3 to achieve a safe structure.
Cooling air is sucked in from the outside of the cover 2 as shown by the arrow A, and the cooling air is passed inside the engine E from inside the cover 2 to the inside of the cover 3 as shown by the arrow opening.
While passing the air as shown by arrow 2, the cooling air is combined and flowed below the supply plate 9 as shown by arrow 2, allowing the cooling air to flow directly to the left side of the aircraft, reducing the temperature inside the cover 2. can be prevented from rising.

In addition, since the cover 3 is a perforated iron plate, the belt 1 and the transmission case 13 side can be seen through the holes in the cover 3 and inspections can be carried out. This makes it possible to prevent the oil temperature in the cab 22 from rising.

In this way, the present invention has a threshing section B installed at the rear of the reaping section A, an engine E installed at the front side of the threshing section B, and the engine E installed at the front lower side of the threshing section B. In a combine harvester configured to transmit power from the engine E through a belt 1, a cover 2 of the engine E is installed so that cooling air can be taken in through the cover 2, and a section on the side of the machine that extends in front of the cover 2 and covers the belt 1, etc. The cover 3 is formed of a perforated iron plate, and the inside of the cover 3 communicates with the cooling air discharge side of the engine cover 2 and the threshing part B.
Since it is installed so that it communicates with the lower front side of the engine cover 2, cooling air flowing inside the engine cover 2 is guided by the cover 3, while wind from the outside is also prevented from flowing through the openings of the cover 3. In this way, the cooling air can flow smoothly and can be passed through the lower part of the front side of the threshing section B to the opposite side of the machine. Temperature rise can be effectively prevented, and the cover 3 covers the belt 1 portion to provide a safety structure.Since the cover 3 is made of perforated iron plate, the inner belt portion etc. can be easily seen through the perforation. It has the advantage of a simple structure and convenient implementation.
