Description

[Detailed Description of the Invention] The present invention provides a mechanism for attaching a fender to a transmission case equipped with an axle equipped with a tillage rotary through a fender that covers the upper side of the tillage rotary or an opening between the fender and the transmission case. Regarding the clutch lever protection structure of a walk-behind mobile agricultural machine, in which the clutch lever is mounted in a vertically extending state and the control handle is extended to the rear of the machine, the purpose is to make a rational and simple improvement of the clutch lever using the original structure. The object of the present invention is to effectively prevent deformation damage caused by collision with other objects, and also to prevent malfunction of the clutch lever due to adhesion of mud thrown up during driving by using the guard structure. .

A characteristic configuration of the clutch lever protection structure of the present invention is that in the above-mentioned walking type mobile agricultural machine, a guard that is long in the longitudinal direction of the machine body and has an L-shaped vertical cross section and covers the lateral outer side and the lower part of the clutch lever is installed on the lower side of the fender. The functions and effects are as follows.

In other words, by focusing on the fact that the clutch lever is installed above and below the fender, and by simply providing a guard for only the lower part of the clutch lever, the fender can be used effectively and the fender can be effectively used. By working together with the guard, it is possible to effectively prevent other objects from colliding with the clutch lever. Furthermore, by using the guard as a cover against splashed mud, malfunction of the clutch lever due to mud adhesion can be prevented. Therefore, it has been possible to provide a clutch lever protection structure that is excellent in overall protection against collisions with other objects and adhesion of mud, and is also advantageous in terms of manufacturing and manufacturing economy.

Moreover, since the guard is open in the front and rear directions,
The mud on the guard can be shaken off by tilting the transmission case forward and backward by moving the control handle up and down, which prevents clutch lever malfunction due to mud buildup and solidification on the guard. There are possible advantages.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

As shown in FIG. 1, a pair of left and right output axles 1 are provided protruding from the lower end, and a pair of left and right fenders 2 are provided.
An engine 5 is attached to the upper end of the transmission case transmission case 3 in a state where it is directly connected to the internal gear transmission mechanism 4, and a pair of left and right rear extensions are attached with a clutch operating tool 6 and an accelerator operating tool 7. control handle 8 and resistance rod 9
are removably connected to a hitch 10 attached to the rear part of the transmission case 3, and further, the output axle 1
A pair of left and right tilling rotary 11 is attached to each of the tillers, thereby forming a walking type tiller.

The resistance rod 9 is constructed by inserting and fitting the tip end of the resistance rod 9 into a boss member 14 attached to the left and right center portions of a frame 13 equipped with a pair of left and right idle wheels 12, and The boss member 14 in the inserted and fitted state is fixed by a lock pin 15 attached to the boss member 14, and is configured to be detachable from the resistance rod 9, and the idle wheels 12 are attached when traveling in a non-working state. By doing so, the vehicle is configured to be able to run smoothly while avoiding running problems caused by the contact of the resistance rod 9 with the ground.

To configure the operating structure of the traveling clutch 16,
As shown in FIGS. 1 to 3, the shift fork 17 for the shift member 16a of the ball clutch 16 interposed in the gear transmission mechanism 4 is attached to the rotating shaft 18 supported through the side wall of the transmission case 3. At the same time, a clutch lever 19 attached to the protruding end of the rotating shaft 18 and the clutch operating tool 6 are interlocked and connected by a release wire 20. Then, the clutch lever 19 is bent into a shape that follows the uneven shape of the side wall of the transmission case 3, and is passed vertically through the gap opening 21 formed between the fender 2 and the side wall of the transmission case 3. By arranging the clutch lever 19 in this position, the clutch lever 19 is prevented from protruding laterally of the fuselage as much as possible, thereby making the fuselage more compact.

To construct the protective structure for the clutch lever 19, a plate-shaped portion 22a corresponding to the "U"-shaped bottom part of a sheet metal member cut into a "U" shape when viewed from the side is bent. While forming the guard 22 which is visually "L" shaped, the transmission case 3
With both ends of the guard 22 and the fender 2 co-tightened together with the bolts 24 to a pair of front and rear bolt seats 23 for fender attachment fixed to the side wall of the 2
2a is fixedly connected to the transmission case 3 so as to be located below the clutch lever 19 and oppositely to the lower part 21, and the fender 2 is also used as a guard. 2 and the bent plate-like portion 22a of the guard 22 to effectively prevent other objects from colliding with the clutch lever 19. or,
The bent portion 22a serving as a guard for the lower part of the clutch lever 19 is formed into a plate shape, and the bent plate portion 22a is disposed opposite to the lower side of the gap 21 through which the clutch lever 19 is inserted. In this way, the guard 22 is also used as a cover for the mud thrown up by the tilling rotary 11, and malfunction of the clutch lever 19 due to adhesion of thrown up mud to the gap 21 can also be prevented. It is configured.

The specific shape of the clutch lever 19 can be modified in various ways, and the structure for arranging it so that it extends vertically with respect to the fender 2 can also be changed between the fender 2 and the transmission case 3. 〓 Interval 2
Instead of forming the lever 1, a lever penetration opening may be formed in the fender 2 itself, and the gaps and openings therebetween are collectively referred to as the penetration opening 21.

The present invention is intended for various types of walking-type mobile agricultural machinery, such as tillers and mowers.

Incidentally, 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.
