Description

[Detailed Description of the Invention] The present invention relates to a bonnet for a tractor, and is designed to facilitate maintenance and inspection of tractor-mounted equipment covered by the bonnet, as well as to facilitate assembly of the bonnet itself.

Conventionally, the bonnet that covers the engine and other equipment mounted on agricultural tractors has had an integral structure, which has made the work complicated, such as having to remove the entire bonnet when inspecting and servicing the steering device, etc. .

The present invention was created in view of such conventional problems, and its features are as follows:
In a bonnet that covers a tank mounted on a tractor and a steering device having a steering case at the lower part behind the tank, the bonnet is detachably fixed to a saddle-shaped upper bonnet and lower ends of both sides of the upper bonnet. Consisting of a pair of left and right side bonnets that are connected, each of the side bonnets has a height that approximately corresponds to the height of the steering case and extends in the front and back direction, and the rear sides thereof are bent inwardly from each other. An opening is formed between the bent edges, and a lid is provided to allow the opening to be opened and closed.

Hereinafter, embodiments of the present invention will be explained according to the drawings.
An engine 2 is mounted near the front of the tractor 1, and a flywheel housing, clutch housing,
Mission cases are arranged in series, and these constitute the fuselage 3.

A rectangular cylindrical steering support 4 of the steering device is installed on the front upper surface of the fuselage 3 in a rearwardly inclined manner via a first support bolt 5, and the steering support 4 is connected to the upper and lower upper and lower casings 6, 7 It is divided into two parts, connected by connecting bolts 8, and both have a sheet metal structure. The upper casing 6 supports a handle shaft 10 having a circular steering handle 9 attached to the top thereof. It is said to be a type handle. Further, a steering control valve 12 is provided in the lower casing 7, and the control valve 12 is interlocked and connected to the above-mentioned handle shaft 10, and when the handle 9 is rotated, pressure oil supplied from a hydraulic pump (not shown) is supplied. The oil is sent to the hydraulic cylinder for steering (not shown). The operation of the hydraulic cylinder causes the front wheels to turn to the right or left, thereby steering the tractor 1.

A fuel tank 13 is provided between the steering support 4 and the engine 2, and the tank 13 is connected to a tank bracket 14 and a second support bolt 15.
It is supported on the fuselage 3 via.

The engine 2, steering support 4, fuel tank 13, etc. are covered by a removable bonnet 16, which is attached to the bonnet 1.
7. The rear bonnet 18 is divided into two parts.
The front bonnet 17 mainly covers the engine 2, a radiator, etc. installed at the front of the engine 2. Further, the rear bonnet 18 mainly covers the steering support 4, fuel tank 13, etc. above and on both sides, and the rear bonnet 18 has the following features:
The main structure includes a saddle-shaped upper bonnet 21 consisting of a top plate 19 and side plates 20, 20, and side bonnets 22, 22 connected to the lower ends of the side plates 20, 20, respectively.

The rear ends of both side plates 20, 20 of the upper bonnet 21 are respectively bent inward to form a pair of left and right first flanges 2.
3, 23 are formed, and the rear opening of the upper bonnet 21 is openably and closably covered by an upper lid body 25 via first flanges 23, 23 and first bolts 24. Also, the top plate 19 of the upper bonnet 21
An instrument panel 26 for vehicle operation is removably attached to the handle shaft 10 relative to the top plate 19.
A flexible cover 27 is used to cover the free-fitting penetration space between the
In addition, the tongue piece 28 at the rear end of the top plate 19 is detachably fixed to the steering support 4 via a connector 29. The side plates 20, 20 mainly cover the sides of the upper casing 6 and the fuel tank 13, and a key switch 31 and the like are attached to the upper lid body 25 via fittings 30. Further, the lower edges of the side plates 20 are each bent inward to form a lower edge flange 32, and a portion of the flange 32 is cut out to form a fitting portion 33.

The upper rear end of each side bonnet 22 is bent inward to form a pair of left and right second flanges 34, 34, and the rear openings of these side bonnets 22, 22 are bent inwardly to form a pair of left and right second flanges 34, 34. and second
A lower lid body 36 is provided with a bolt 35 to open and close the lid. Further, the lower end of the side bonnet 22 extends further downward to form a skirt portion 37, which is fixed to the body 3 with bolts 38. The side bonnets 22, 22 mainly cover the lower casing 7.
and covers the sides of the tank bracket 14 area, the lower end of the lower lid body 36 is brought close to the top surface of the fuselage 3, and the lower end of the skirt portion 37 is connected to the step 3 protruding from the side surface of the fuselage 3.
9 is placed close to the top surface.

The upper edges of the side bonnets 22 are each bent inward to form an upper edge flange 40, and a portion of the flange 40 is cut and raised to form a fitted portion 41, which is connected to the fitting portion 33. The upper and side bonnets 21 and 22 are removably connected to each other by fitting and removing the fitting part 41, and the lower and upper edge flanges 32 and 40 can be freely overlapped. Further, when the fitting part 33 and the fitted part 41 are fitted together, and the lower and upper edge flanges 32 and 40 are in an overlapping state, a through hole 42 is formed through the fitted part 41;
A connecting bolt 44 is communicated with a through hole 43 penetrated through the lower end of the side plate 20, and the upper and side bonnets 21,
22 are detachably connected. In addition, 45 is a seat, and 46 is a gear lever.

Thus, by removing the upper bonnet 21 or the upper lid 25 from the body 3 side, it is possible to inspect the universal joint 11 of the handle shaft 10, and by removing the side bonnets 22, 22 or the lower lid 36, The control valve 12 can be inspected, etc.

According to the present invention, since the rear bonnet 18 has a combination structure of divided bodies, there is no need to remove the entire rear bonnet 18 when inspecting the tractor-mounted equipment covered by the rear bonnet 18, but only the necessary parts. It is sufficient to remove it, and therefore, these operations are facilitated and beneficial. That is,
The pair of left and right side bonnets 22, which can be attached and detached to the lower ends of both sides of the upper bonnet 21, has a height that approximately corresponds to the height of the steering case. Maintenance can be easily performed by removing one or both of the bonnets 22.

Further, since the side bonnet 22 extends in the front-rear direction and its rear portions are bent inwardly, the rigidity can be increased together with the saddle-shaped upper bonnet 21. Moreover, the bent edges of the side bonnet 22 Since the space in between can be opened and closed with the lid 36,
There is an advantage that the steering case 7 can be maintained by leaving the side bonnet 22 as it is and opening the lid 36.
