Description

[Detailed Description of the Invention] The present invention relates to a front hitch, starter motor cover, and bumper mounting structure for a walk-behind cultivator.

Conventionally, in walk-behind cultivators, a front hitch is attached to the front end of the body frame on which the prime mover is mounted, and other working machines are connected to the front hitch by this hitch.

Such a front hitch is formed into a substantially U-shape when viewed from the side, is attached to the front end of the fuselage frame, and has a bumper erected upward on the top of the hitch.
The bumper is configured to protect the prime mover.

Further, a starter motor is attached to the front of the prime mover, and a cover for covering the starter motor is removably attached to the prime mover to facilitate inspection of the starter motor.

However, the above structure has the drawback that when inspecting the starter motor, the bumper installed at the front end of the fuselage frame is located in front of the cover, making it difficult to remove the cover. ing.

In the present invention, a vertical hitch body mounting plate is installed on the top surface of a flat flange plate, and the hitch body, which is approximately U-shaped in side view with an opening at the front, is connected to the front end of the mounting plate. to configure the front hitch,
The front hitch is fixed to the front end of the fuselage frame on which the prime mover is mounted via a flange plate, and the lower end of the starter motor cover that covers the starter motor provided at the front of the prime mover is attached to the hitch body mounting plate. This invention provides a front hit, starter motor cover, and bumper mounting structure for a walk-behind cultivator, in which a substantially U-shaped bumper is attached to the upper end of the cover so as to protrude forward from the front ends of the cover and the hitch body. be.

The embodiment of the present invention will be explained in detail based on the drawings.
A indicates a walk-behind tiller, and this tiller A
is equipped with a prime mover 2 at the front of the fuselage frame 1,
A transmission case 3 is disposed behind it, running wheels 4 are disposed on both left and right sides of the case 3, and a chain case 5 is disposed behind the transmission case 3, and a chain case 5 is disposed on both sides of the case 5. A tilling shaft 7 with tilling claws 6 connected to the side is provided protrudingly, and a steering handle 8 is extended from the rear side of the upper part of the transmission case 3 to the left and right rear. While traveling through the field by driving wheels 4, the tilling claws 6 are rotationally driven by the power of the prime mover 2 to till the surface of the field.

A front hitch 9, starter motor 10, and bumper 11 are installed in front of the prime mover 2.
Of these, the front hitch 9 has vertical hitch body mounting plates 13 erected on the left and right positions on the flange plate 12, and a hitch body 14 that is approximately U-shaped in side view is connected between the front edges of the mounting plate 13. It is configured as follows.

Both sides of the flange plate 12 of the front hitch 9 protrude from both left and right sides of the hitch main body mounting plate 13 as mounting flanges for attachment to the fuselage frame 1, and bolts are attached to the upper surface of the front end of the fuselage frame 1 through the flanges. It is mounted and fixed at 20.

Further, the upper edge of the hitch main body mounting plate 13 is formed in a substantially U-shaped forward upward slope, and the front end edge is formed high, so that the height is approximately half that of the hitch 14.
A hitch 14 is configured to protrude upward from the upper end of the mounting plate 13. Further, connection holes 15 are bored in the upper and lower horizontal parts 14' of the hitch main body 14.

The starter motor cover 10 also includes a front side plate 1 that covers the front side of the starter motor M located in front of the prime mover 2.
A horizontal side plate 10'' is formed which is bent backward from both sides of 0' to protect the starter motor M from the front and left and right sides. A U-shaped notch 17 is formed in the hitch body mounting plate 13.
By fitting both outer sides of the front plate 1
The lower end edge 16 of the starter motor cover 10 is configured so that it can be installed as downwardly as possible without interfering with the mounting plate 13, and the upper half of the hitch main body 14 is attached to the front side plate 10' of the starter motor cover 10. It is located at the front of the lower half of the front plate 10' to maintain the guard function of the front side plate 10'.

Further, the bumper 11 is formed into a substantially U-shape in plan view, and both ends thereof protrude forward from the prime mover 2 and are connected and supported by a stay 18 located directly above the starter motor cover 10. The surface of the bumper 11 is covered with a shock absorber 19 made of a synthetic resin material, and the front end of the bumper 11 protrudes slightly forward and laterally from the hitch body 14, and is placed above the front plate 10' of the starter motor cover 10. half the
It is protected from interference from the outside, and by protruding from the hitch body 14, the hitch body 1 may be inadvertently damaged when the tiller is being inspected for maintenance.
This is to prevent accidents such as falling due to contact with 4.

In addition, since the bumper 11 is attached to the upper end of the starter motor cover 10, the bumper 11 does not cause any hindrance, and the cover 10 can be easily removed and inspected inside, and the bumper 11 and starter motor cover 10 and the front hitch 9 are consolidated, the design is also good.

According to the present invention, the starter motor cover is disposed above the front hitch, and a substantially U-shaped bumper is disposed above the cover and protrudes from the front end of the hitch body, so that the bumper does not cause any hindrance. First, the starter motor cover can be easily removed and the starter motor etc. can be inspected easily, and the lower half of the starter motor cover can be protected by the hitch body, and the upper half of the starter motor cover can be protected by the bumper. In addition, since the starter motor is covered with the starter motor cover, the starter motor is not damaged by splashing of muddy water and has the effect of eliminating electrical failures caused by rusting or the like.
