Description

[Detailed Description of the Invention] The present invention relates to a cover structure for a rear engine in a self-propelled self-extraction system.

In other words, the threshing machine is mounted on the loading platform at the front of the machine supported by a pair of left and right crawlers, with its feed chain on the rear side, perpendicular to the direction of travel, and the engines etc. are installed at the rear. In the self-propelled self-extraction system, in which a handle is extended to the grain culm supply side of the threshing machine, an air intake duct for the engine that also serves as a cover is installed at the upper side of the engine on the grain culm supply side of the thresher in the front and back direction along the side of the engine. There is no need to provide a separate cover, and the intake duct covers the engine to ensure safety, and an outside air intake port is opened at the rear end of the intake duct for threshing. To provide a simple structure which can be suitably implemented by sucking air from a place on the grain supply side of the machine and at the rear side of the machine body where the least amount of dust is floating.

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

Figure 1 shows a side view of a self-propelled self-eliminating machine. A threshing machine A is loaded on a loading platform 1 at the front of the machine supported by a pair of left and right crawlers 8, with its feed chain on the rear side and perpendicular to the direction of movement. The diesel engine E, the transmission case 9, etc. are installed at the rear of the machine and are covered with a cover C except for the side of the diesel engine E on the grain culm supply side. A support rod 10 is installed from the front to the top on both sides of the cover C, and support rods 11, 11 are erected at the rear of both sides, and a planar U-shaped handle is connected to the support rod 10 from the upper rear of the cover C to the rear. 2 is extended, and a control lever 12 is installed on the handle 2 to constitute a control section 13.

In addition, a paddy holder 1 is located below the left side of the control section 13.
4 is installed, and a main paddy outlet pipe 16 and an overflow paddy outlet pipe 17 extending above the paddy holder 14 are installed at the tip of the grain lifting pipe 15 extending diagonally rearward from the lower side of the threshing machine A. It is constructed so that paddy can be placed in a paddy bag that is hung vertically and supported by a paddy receiving rod 18, but when the threshing machine A is lowered, it becomes a transport vehicle.

Engine E on the grain culm supply side of the threshing machine A
An intake duct 3 having a case structure and long in the front-rear direction and thin in the lateral direction is attached to the upper side of the engine. Accordingly, the mounting structure is such that the upper side of the engine E can be covered, and the left side of the engine E below the intake duct 3 is exposed to the side, and the cranking starter shaft 19 is installed in that part. Set and configure.

At the rear end of the intake duct 3 that extends to the base side of the handle 2, an outside air intake port 4 facing toward the rear of the aircraft body is opened at the lower side of the handle 2.
A communication port 21 communicating with the engine E side is formed on the inner surface of the front end side of the intake duct 3, which is installed by stretching and is slightly enlarged, and a filter facing from the inside is formed in the communication port 21. 5 is inserted into the pin 22 to be detachably attached, and an opening 7 large enough to allow the filter 5 to be inserted and removed is formed on the outer surface of the end of the intake duct 3, which is the outer side of the filter 5. The opening/closing lid 6 is attached to the part 7 via a hinge 23 so that it can be opened and closed freely, and the knob screw 24 inserted into one side of the opening/closing lid 6 is attached to and removed from the screw hole 25 on one side of the opening 7. They are installed and configured so that they can be freely screwed together.

A flywheel cover 26 for the engine E is provided with a rear portion projecting rearward from the rear surface of the cover C, which is the front lower part of the handle 2, and an opening/closing lid 27 is installed on the right side thereof. When opened, the rope starter ring 28 for the engine E on the inside is installed so that the rope can be operated from the outside.

Therefore, the intake duct 3, which is long in the front-rear direction and is provided along the side of the engine E, has a structure that covers the upper side of the engine E and also serves as a safety cover. The net 20, which is on the supply side and opens toward the rear of the fuselage, sucks in dust-free air from the outside air intake port 4, further filters it through the filter 5, and supplies clean air to the engine E side.

Further, when cleaning or switching the filter 5, the opening/closing lid 6 is opened and the filter is inserted or removed through the opening 7.

In this way, the present invention mounts the threshing machine on the loading platform at the front of the machine, supported by a pair of left and right crawlers, with its feed chain on the rear side, perpendicular to the direction of movement, and the engines etc. are installed at the rear. At the same time, in the self-propelled self-removal system in which a handle is extended to the rear of the engine, an intake duct that is long in the front and rear direction along with the engine is provided at the upper side of the engine on the grain culm supply side of the threshing machine. The duct directly covers the side of the engine, and the outside air intake port is opened at the rear end of the intake duct. It is covered with a long intake duct to ensure safety, and there is no need to provide a separate cover.Furthermore, since the lower side of the stock passage section is covered by the intake duct, it is possible to reliably prevent dust from adhering to the engine. It is possible to prevent engine overheating while reducing the number of points, and since the outside air intake port is opened at the rear end of the above-mentioned intake duct, it is possible to prevent dust from floating on the grain culm supply side of the threshing machine and at the rear of the machine. Air can be sucked in from the outside air intake port and supplied to the engine, allowing the engine to operate stably and continuously.In addition, the outside air intake port is easily visible to the driver, which further reduces engine overheating due to dust adsorption to the outside air intake port. It can be prevented.

As a result, the present invention has the advantage of being able to suitably implement both the safety of the driver and the safe operation of the engine, despite its simple configuration.
