Description

[Detailed explanation of the invention] Industrial application field This invention relates to an engine cover.
Can be used for agricultural machinery such as combines and harvesters.

Prior Art A fuel tank that stores fuel for an engine may be configured separately from the engine cover, or may be configured such that the fuel tank is provided inside the engine cover and the fuel inlet is peeked out from a part of the engine cover. is common.

Problems to be Solved by the Invention The design of enclosing the fuel tank within the engine cover has flaws such as restricting the fuel tank to a special shape and tending to limit the capacity. The fuel tank is configured to largely protrude above the engine cover, and the engine cover is configured to be detachable.

Means for Solving the Problems This invention is based on an engine cover 2 which is removable to cover the upper side of the engine 1, and a fuel tank 3 is placed on the upper side to catch the fuel that leaks during fuel supply and guide the discharge. An opening 5 facing the saucer 4
By installing the engine cover 2, an engine cover is constructed in which the outer peripheral edge 6 of the saucer 4 and the inner peripheral edge 7 of the opening 5 are brought into close contact.

Effect of the invention When the engine cover 2 is installed, the opening 5
The fuel tank 3 protrudes upward, and the inner peripheral edge 7 of the opening 5 and the outer peripheral edge 6 of the saucer 4 are in close contact with each other. Therefore, even if some of the fuel overflows outside the fuel tank 3 when fuel is injected into the fuel tank 3, the fuel flowing into the opening 5 is received by the saucer 4 and guided for discharge.
It does not enter the engine 1 part through the gap between the saucer 4 and the engine cover 2.

Also, when removing the engine cover 2, open the opening 5.
The inner circumferential edge 7 and the outer circumferential edge 6 of the saucer 4 are spaced apart, and the saucer 4 and the fuel tank 3 above it can be left in their original positions and opened.

Effects of the invention In this way, the fuel tank 3 remains in the fixed position with the lower saucer 4, and the attachment and detachment of the engine cover 2 can be simplified, and the fuel tank 3 is made to protrude above the engine cover 2. state,
Since it is avoided from being covered by the opening 5,
By exposing the fuel tank 3 above the engine cover 2, the structure of the engine cover 2 itself can be simplified, and even if the fuel injected into the fuel tank 3 leaks, it can be caught by the saucer 4. ,
It is safe to prevent intrusion into the internal engine 1 from between the outer circumferential edge 6 of the saucer 4 and the inner circumferential edge 7 of the opening, which are brought into close contact with each other.

Embodiment In addition, in the illustrated example, the traveling body 8 of the combine harvester
The engine 1 is mounted on the fuselage 8, and the engine cover 2 covering the upper side or outer peripheral surface of the engine 1 is installed on the aircraft 8.
Put on and take off the top. An intake network 9 is provided on the outer surface of the engine cover 2, and the inner surface is opened to form a cooling air outlet section 10. The opening 5 provided on the top surface may have an inner end open so that the engine cover 2 can be horizontally moved outward and the opening 5 and the fuel tank 3 can be fitted into and separated from each other.
The inner circumferential edge 7 of the opening 5 is formed to be sloped downward toward the opening 5 to prevent fuel from penetrating along the inner surface of the engine cover 2. 1
Reference numeral 1 connects the front and rear engine cover 2 parts of the opening 5, and is formed so as to bypass the upper part of the fuel tank 3 in a loop shape. Reference numeral 12 denotes a pilot's seat, which is attached to the upper side of the engine cover 2.

The saucer 4 is supported by a pipe 13 with respect to the fuselage 8 and is opposed to the lower side of the opening 5 of the engine cover 2. The outer peripheral edge 6 of this saucer 4 is inclined upward and can be joined to the lower surface of the inner peripheral edge 7 of the opening 5. An elastic seal such as rubber may be interposed at this joint. The upper end of the pipe 13 communicates with the inside of the saucer 4, and the lower end is opened to the outside of the bottom machine.
This structure allows leaked fuel to be guided downstream and discharged outside the aircraft. Note that this pipe 13 may be used as a support, and a separate hose may be provided to guide the discharge of leaked fuel.

The fuel tank 3 is provided above the saucer 4 and is directly attached to the saucer 4, but it may be placed on another member, or it may simply be removably received on the saucer 4. It may be a configuration. 14 is an opening/closing lid.

15 is a radiator, which is provided outside the engine 1 and sucks outside air through the intake network 9 by the rotation of the suction fan 16 of the engine 1, and supplies the air to the radiator 1.
This is a series of ventilation configurations in which after cooling the engine 1, the outer periphery of the engine 1 body is further cooled, and air is discharged from the air outlet section 10 on the opposite side. 17 is a power take-off pulley. 18 is a control platform in front of the cockpit 12, and 19 is a crawler.

A fuel filter 20 is provided to communicate between the upper fuel tank 3 and the fuel injection pump 21 of the engine 1. On the fuel injection pump 21 side of the fuel filter 20, there is a transparent filter that communicates with the upper part of the fuel tank 3. A pipe 22 is provided so that air can be removed from the pipe 22 while the fuel filtered by the fuel filter 20 flows to the injection pump 21, and the remaining amount in the fuel tank 3 can be known by the transparent pipe 22. I can do it.

The engine cover 2 is fixed to the fuselage 8 with fasteners such as bolts. When removing the engine cover 2, remove this fastener and move it outward or upward. The fuel tank 3 and the saucer 4 are separated from each other and removed from the engine 1.

Claims (1)

[Scope of utility model registration request] An engine cover 2, which is removable to cover the upper side of the engine 1, is provided with an opening 5 facing a saucer 4 for locating a fuel tank 3 on the upper side and receiving and discharging fuel that leaks during fuel supply. By attaching the engine cover 2, the outer circumferential edge 6 of the saucer 4 and the inner circumferential edge 7 of the opening 5 are brought into close contact with each other.
