Description

[Detailed Description of the Invention] The present invention relates to the structure of an agricultural tractor that can be equipped with a tillage rotary etc. in a manner that allows it to be raised and lowered freely.The purpose of the invention is to
The clutch housing, which firmly connects the driving part and the transmission case, is finished to give it a beautiful appearance.By effectively utilizing the clutch housing cover, it can be attached to the main body of the step and operation panel boxes, which were previously installed individually. The purpose is to facilitate the assembly of

The structure of the agricultural tractor according to the present invention is such that the upper part of the clutch housing is attached to a step that is relatively long in the front and back direction and is attached along both left and right outer sides of the clutch housing that firmly connects the driving part and the transmission case. A cover having an inverted U-shape in front view so as to cover the entire left and right sides so as to straddle the clutch housing is fixedly integrated with an operation panel box, and the front opening thereof has an inner shape that straddles the clutch housing. The cover is characterized in that a substantially gate-shaped heat shield plate having a width larger than the width of the U-shape of the cover is fixedly integrated with the cover via a stay.

That is, according to the present invention, the step, cover, operation panel box, and heat shield are assembled into an assembly based on the step having sufficient rigidity, so that the clutch housing part can be assembled by simply assembling this one assembly. At the same time, the assembly of the attached components has been made significantly easier. Moreover, since the step, cover, operation panel box, and heat shield plate are fixed and integrated through the stays in the above-mentioned integration, they can be reinforced with each other to form an integrated product with extremely improved strength. Ivy.

Furthermore, since it covers the entire area of the upper and left and right sides of the clutch housing, it is possible to suppress the outward diffusion of gear noise emitted from the clutch housing, and the heat shield also suppresses engine noise. This has the advantage of suppressing the propagation of noise to the operating section and providing a highly soundproofing effect.

Hereinafter, an embodiment of the present invention will be described based on the drawings. A driving unit 1 includes a fuel tank 1B disposed at the rear of an engine 1A, and is supported by a pair of left and right steerable front wheels 9. and a transmission case 2 supported by a pair of left and right drivable rear wheels 10, 10 are fixedly connected via a clutch housing 3, and compared in the front and back direction along both left and right sides of this clutch housing 3. This is an agricultural tractor in which long steps 4, 4 are arranged, and a steering handle 12 is provided upright in a position in front of a passenger seat 11 attached to the transmission case 2. It is attached to arms 3A, 3A, which protrude from the clutch housing 3 on both the left and right sides near both front and rear ends thereof, via rubber vibration isolators 8, bolts and nuts 13, and these steps 4, 4. for,
a cover 5 having an inverted U-shape in cross section and covering a portion of the clutch housing 3 above the steps 4;
Of the bonnet 7 for the driving unit 1, an operation panel box 6 into which the post of the handle 12 is inserted has a rear end,
The cover 5 has an inner shape that straddles the clutch housing 3 to insulate and close the front opening of the cover 5.
The rear bonnet portion 7A for the contents of the fuel tank 1B is fixedly integrated with the rear bonnet portion 7A for storing the contents of the fuel tank 1B, which has a substantially gate-shaped heat shield plate 14 having a width larger than the width of the U-shape of the fuel tank 1B.

In the figure, reference numerals 15, 15 are fenders for the rear wheels 10, 10, and 16 is a stay for attaching the rear bonnet portion with bolts and nuts 17 fixed to the front ends of the steps 4, 4.
