Description

[Detailed Description of the Invention] The present invention relates to improving the protection structure of the tractor, more specifically, the clutch operating part.The present invention is a simple modification that makes effective use of the original structure of the tractor to remove the clutch operating shaft protruding from the clutch housing from a foreign object. The purpose is to provide as much protection as possible from contact with.

A tractor according to the present invention is provided with a frame for attaching to a structure protruding laterally outward at a lateral side of a clutch housing, wherein the frame is attached to an end of the frame on the clutch housing side. Attaching a mounting seat plate, and fixing a portion near the outer periphery of the mounting seat plate to a protrusion formed protruding from a side surface of the clutch housing,
A space is formed at the attachment point of the frame to the clutch housing, the lateral outer side of which is covered by the attachment seat plate, and a shaft end of the clutch operating shaft protruding from the clutch housing is positioned within this space. It is characterized by being seductive.

That is, in order for the clutch operation shaft to protrude from the clutch housing, for example, there is a gap between the clutch housing and a mounting seat plate for attaching a mounting frame for a structure such as an engine bonnet or a footstep for the operator to the clutch housing. By locating it, the mounting seat plate can have a protector function for the operating shaft.
It has now been possible to prevent damage to the operating shaft due to contact with foreign objects as much as possible.

Moreover, since the structure effectively utilizes the mounting seat plate, which is the original structure of the tractor, as a protector, and has a protrusion for the mounting seat plate protruding from the side of the clutch housing, it can be easily modified. It was advantageous in terms of production and cost.

Embodiments of the present invention will be described below based on illustrative drawings of agricultural tractors.

A transmission case 7 is connected to the rear of the engine 1 via a clutch housing 5 that includes a clutch mechanism 4 that connects and disconnects transmission from the engine 1, and a pair of left and right steering fronts are connected to a frame 2 attached to the engine 1. wheels 8,8,
A pair of left and right driving rear wheels 9, 9 are attached to the transmission case 7.
are mounted on shafts, and a pilot seat 3 is disposed above the mission case 7.

When a bonnet 11 is attached to cover the engine 1, its lower end is connected to the frame 2, and its rear end is connected to the clutch housing 5, as shown in FIG.

That is, with a space S provided between the four protrusions 13 protruding outward from the side of the clutch housing 5 and the clutch housing 5, the above-mentioned A pair of left and right frames 15 are attached to the clutch housing 5 so as to protrude in the lateral direction of the vehicle body via mounting plates 14 bolted to the protrusions 13.
．． 15, dustproof covers 16, 16 for the feet of the operator are attached to the tips of these horizontal frames 15 and 15, respectively, and a bonnet 11 portion is connected to the dustproof covers 16.16.

A step 17 for resting the operator's feet is attached to the horizontal frame 15 on the left side of the vehicle body, and a pedal 18 is provided in front of the step 17 and is connected to the clutch mechanism 4. It is designed for turning on and off.

A rotation operating shaft 19 for the clutch mechanism 4 constitutes an interlocking mechanism between the clutch mechanism 4 and the pedal 18.
In order to provide the frame mounting seat plate 14 with a protector function for protecting the operating shaft 19 from contact with foreign objects, the clutch housing 5 and the seat plate 1 are
A lever 20 is attached to the protruding end of the operating shaft 19 and protrudes from the clutch housing 5 while being located in the space S between the lever 20 and the pedal 1.
8 are pivotally connected by a rod 21, so that the pedal 1
The operation shaft 19 is rotated by the depression and release operations of 8.

According to the operation shaft protection structure, as shown in FIG. 3, the seat plate 14 is bent so that the connection part to the protrusion 13 is closer to the clutch housing 5 side than the connection part to the horizontal frame 15. Because of this, the amount of protrusion of the protrusion 13 from the clutch housing 5 can be suppressed, and as a result, the attachment portion of the pedal 18 and the seat plate 14 to the protrusion 13 can be made as functional as possible, and the seat plate 14 can be easily operated by the pedal 18. It is possible to prevent obstacles as much as possible.

Although inferior in this respect, the seat plate 14 may be configured as a flat plate as shown in FIG.
