Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an agricultural tractor that is provided with a muffler and an air cleaner on both left and right sides of the engine, and an engine bonnet that covers the upper side of the engine.

In conventional agricultural tractors of this type, separate covers are provided to cover the upper sides of the air cleaner and the muffler, respectively, in order to prevent rainwater from falling on the air cleaner or causing burns due to contact with the muffler. However, in this case, the number of parts for the covers including the engine bonnet was extremely large, which was disadvantageous in terms of manufacturing and assembly.

In addition, as a means to improve such assembly defects, the upper plate of the engine bonnet is simply extended laterally outward, and the extended portion of the upper plate is used to connect the upper side of the muffler and air cleaner. However, in this case, the upper side plate of the engine bonnet would protrude outward to a large extent, resulting in poor visibility of the left and right sides of the lower front of the fuselage, which could cause crops to be accidentally planted during agricultural work. It may cause damage.

In view of the above-mentioned circumstances, an object of the present invention is to facilitate the assembly work related to the engine bonnet while providing a good line of sight to both left and right sides of the lower front of the aircraft body. The engine bonnet is formed into a gate-shaped cross section that covers the upper part of the engine, and an eave-like cover part that covers the upper side parts of the muffler and the air cleaner is attached to the lower edge of the left and right side plates of the gate-shaped bonnet so that their upper end surfaces It is characterized by being integrally connected at a position lower than the upper end surface of the engine bonnet.

In other words, by integrally connecting the eaves-like cover portion for the muffler and air cleaner to the lower edge of the engine bonnet, the number of parts required for attaching these parts can be reduced as much as possible.
Moreover, since the upper end surface of the eave-like cover section is located below the upper end surface of the engine bonnet, the space between the outer surfaces of the left and right side plates of the engine bonnet and the upper end surface of the eave-like cover section can be passed through the space between the left and right sides of the lower front part of the aircraft. You can easily see through the parts.

Therefore, it is possible to improve the visibility to both left and right sides of the lower front part of the fuselage, and to facilitate the assembly work related to the engine bonnet.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 1, a frame 3 that supports a pair of left and right front steering wheels 2, 2 is fixedly connected to the engine 1 in a state of protruding forward, and a clutch housing 4 is attached to the rear of the engine 1. A transmission case 6 that pivotally supports a pair of left and right driving rear wheels 5, 5 is fixedly connected in this order, and a mechanism for steering and rotating the driving front wheels 2, 2 is provided on the upper part of the transmission case 6. A steering handle 7 and a driver's seat 8 are arranged to constitute an agricultural tractor.

Further, an engine bonnet 10 that covers the upper side of the engine 1 and the engine radiator 9, and an operator box 11 that includes a seat section 11A and a step section 11B to which the driver's seat 8 is attached,
They are individually molded in resin so that they can come into contact with each other from the front and rear directions, and in the state of contact, they surround the steering post 12 of the steering handle 7, and both of them 10 and 11 are fixed on both left and right sides of the steering post 12. At the same time, at the rear end of the engine bonnet 10,
A three-dimensional hollow resin instrument panel 13 projecting upward from the top surface of the engine bonnet 10 is attached.

This engine 1 is installed on one side of the engine 1.
A muffler 14 in a longitudinal direction, which is connected to the exhaust manifold 1A, is disposed with its exhaust port located forward, and on the side of the horizontal ground,
An air cleaner 15 connected to an intake manifold 1B of an engine 1 is disposed with its intake port facing forward and opening.

Thus, when viewed from the front, the left and right side plates 1 of the engine bonnet 10 cover only the upper part of the engine 1.
An eave-like cover portion 1 that covers the upper and lateral outer portions of the muffler 14 and air cleaner 15 over the lower edges of 0A, 10B and the front side plate 10C.
6... are integrally molded during resin molding of the engine bonnet 10 with their upper end surfaces 16a... being lower than the upper end surface 10a of the engine bonnet 10, and the eaves-like cover portions 16...
Holes 17, 17 that open forward and laterally outward are formed in the front corner of the frame, respectively, and brackets 18, 18 and 18, 18 are connected to the peripheral edges of the holes 17, 17.
Direction indicator lights 19, 19 are attached to the eaves-like cover portions 16 so as to protrude forward and laterally outward.

Note that although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
