Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a bonnet cover mounting structure for enclosing an engine and various other devices mounted on a mobile agricultural machine such as an agricultural tractor.

[Prior Art] Conventionally, a bonnet cover that covers an upper part and a side part of an engine room where an engine and various other devices are mounted on a front part of an airframe chassis is provided by horizontally attaching a fastening pin provided in the engine room. There is known a structure in which an engaging member provided on the inner side surface of the bonnet cover is provided so as to protrude forward of the machine body, and is engaged with and attached to the engaging pin.

However, since this one is configured so that the engagement pin is projected to the engine room side, it interferes with the inspection and maintenance work of the air filter, cell motor, etc. arranged around the engine, and for safety. However, when the vehicle is running on rough roads with the bonnet cover attached, the bonnet cover will shift forward due to the vibration of the aircraft, and There is also a serious safety drawback that the bonnet cover will fall off the aircraft when the engagement with the engagement member is released, and the advent of a bonnet cover mounting structure that solves the above drawbacks was eagerly awaited. .

[Problems to be Solved by the Present Invention] In view of the above-mentioned circumstances, the present invention was devised to eliminate the conventional drawbacks, and the purpose thereof is to attach a bonnet cover. The landing pins project toward the rear of the machine on the tank bracket that secures the fuel tank at the rear of the engine to facilitate maintenance and inspection of the air filter, carburetor, etc. around the engine. An object of the present invention is to provide a mounting structure for a bonnet cover in a mobile agricultural machine, which is capable of preventing frontward displacement.

[Means for Solving the Problems] In order to solve the problems, the technical means adopted by the present invention are:
To cover the engine mounted on the front part of the machine body and the fuel tank arranged on the rear side of the engine with a detachable bonnet cover, the vertical surface of the tank bracket on which the fuel tank is mounted has It is characterized in that an engaging pin is provided so as to project, and an engaging member that engages with the engaging pin is provided on the inner surface of the bonnet cover.

[Advantage of the Invention] Therefore, according to the present invention, maintenance and inspection in the engine room can be easily performed, and the bonnet cover can be prevented from falling off or being displaced forward to ensure a reliable bonnet cover operation. The locked state can be secured.

[Embodiment] The configuration of the present invention will be described in detail with reference to an embodiment shown in the drawings.

1 to 3, 1 is an agricultural tractor, 2 is a machine chassis, and a front part of the machine chassis 2 is
An engine room 4 surrounded by the bonnet cover 3 is formed. Reference numerals 5 and 5 are front wheels, and 6 and 6 are rear wheels. A front grill 7 is erected on the front surface of the machine body chassis 2, and a bonnet cover 3 constitutes a bonnet 8.

An encidin 9 is mounted in the engine room 4, and a fuel tank 11 is disposed behind the engine 9 and supported by a tank bracket 10. Vertical surfaces 10a, 10b are formed on both left and right ends of the tank bracket 10, and the vertical pins 10a, 1b are respectively formed on the vertical surfaces 10a, 10b.
1b is horizontally projected toward the rear of the agricultural tractor 1.

Further, the vertical surfaces 10a, 10b are formed along the inner surface shape of the lower end portions on both sides of the bonnet cover 3, and the hot air generated by the engine 9 causes the driving operation unit 12 and the driving operation unit 12 provided at the rear of the fuel tank 11. It is configured to prevent hot air from flowing into a control unit (not shown).

Locking pins are provided on the inner surfaces of both lower ends of the bonnet cover 3.
The engaging members 13a, 13b engaging with 11a, 11b are screwed,
By expanding the lower end portion of the bonnet cover 3 in the horizontal direction, the bonnet cover 3 can be attached to and detached from the main body of the agricultural tractor 1.

Locking pins 11a and 11b and locking member 1 configured as described above
In the engaged state, the vertical surfaces 10a and 10b of the tank bracket 10 prevent forward movement of the bonnet cover 3 and prevent the bonnet cover 3 from falling off and moving forward due to running on a rough road. Yes, the engagement pin 10a,
Since 10b does not project to the engine room 4 side, maintenance and inspection of filters, carburetors, etc. (not shown) can be facilitated, and the engine room 4 can be quickly serviced.

[Effect of the Invention] In short, according to the present invention, in order to cover the engine mounted on the front part of the machine body and the fuel tank arranged behind the engine with the removable bonnet cover, the fuel tank is mounted. On the vertical surface of the tank bracket to be placed, the engaging pin is provided so as to project rearward of the machine body, and the engaging member that engages with the engaging pin is provided on the inner surface of the bonnet cover. Although it has an extremely simple structure in which it projects from the engine room toward the rear of the machine, it can not only reliably prevent the bonnet cover from shifting to the front when driving on rough roads, but also maintains the engine room. Therefore, the maintenance work such as inspection can be facilitated, and the safe working condition of the mobile agricultural machine can be secured, which is an extremely useful practical effect.
