Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention includes a bifurcated handle frame extending rearward from the top of the transmission case, and a bifurcated handle frame extending from the transmission case to the crotches of the left and right handle frames. This invention relates to a walking type mobile agricultural machine equipped with a lever guide that passes through a gear shift lever.

[Conventional technology]

Conventionally, as in the above structure, a lever guide is provided on the bifurcated part of the handle frame. There is something about the mounting structure.

[Problem that the invention attempts to solve]

As mentioned above, when producing a bifurcated handle frame, for example, if the sheet metal material is bent,
Normally, the steering force concentrates on the handle frame, which can cause distortion and cracks in the sheet metal material of the bifurcated parts.

Further, even if the handle frame is manufactured by welding and fixing the left and right frames to each other, the same problem as described above occurs, and there is still room for improvement.

The purpose of the present invention is to improve the strength of the handle frame through reasonable modification.

[Means for solving problems]

The feature of the present invention is that, in the above-mentioned walking-type mobile agricultural machine, a sheet metal material that is bent and formed so that spaces open upward and downward are formed in the front and rear, respectively, is placed between the left and right handle frames behind the lever guide. and connect both ends thereof to the left and right handle frames, and use the upper open space as a tool storage section,
Furthermore, the rear surface of the sheet metal material is used for the meter panel, and its functions and effects are as follows.

[Effect]

As shown in Figures 1 and 2, when the above characteristics are applied to a power tiller, it is bent to form a space that opens upward and downward, and the cross-sectional shape is "S" shaped and extends in the left and right direction. A sheet metal material with high elastic strength is disposed between the left and right handle frames 7, 7, and when a steering operation force is applied to the handle frames 7, 7, the left and right handle frames 7, 7 are It is operated integrally via the sheet metal material 11.

[Effect of idea]

Therefore, the strength of the handle frame can be improved without attaching any special reinforcing members by a relatively simple modification that connects the sheet metal material bent and formed to form the tool accommodating part and the meter panel between the left and right handle frames. Ivy.

〔Example〕

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

As shown in Fig. 3, a transmission case 2 that transmits power to a pair of left and right wheels 1 is arranged approximately in the center of the aircraft body, and an engine 4 is mounted on a frame 3 extending forward from the transmission case 2. ,and,
A belt case 5 that transmits the power from the engine 4 to the transmission case 2, and a chain case 6 that transmits the power from the transmission case 2 to the rotary tiller R connected to the rear of the machine are attached to the left and right sides of the machine, respectively. A pair of left and right handle rods 8, 8 are attached to bifurcated handle frames 7, 7 provided rearward from the upper part of the transmission case 2, thereby forming a tiller as an example of a walking type mobile agricultural machine.

As shown in FIGS. 1 and 2, the handle frames 7, 7 are made of sheet metal material, and the shift levers 9a, 9b extend from the transmission case 2 at the crotches of the left and right handle frames 7, 7. Weld and fix the lever guide 10 passing through the left and right handle frames 7, 7.
There is a space S open above and below between the rear parts of the
T is formed at the front and rear, the upper open space S is used as a tool accommodating part, and the sheet metal material 11 whose rear surface is used for the meter panel 11a is connected and fixed by bolts 12, 12, improving the strength of the handle frames 7, 7. I'm letting you do it.

Further, a bracket 13 is provided at the lower end portion of the lever guide 10, and short slits 11s, 11s are formed at two locations on the left and right at the top of the intermediate vertical wall 11b of the sheet metal material 11.
The lid cover 14 has an extending portion 14a formed in the front so that the rear end protrusions 14t, 14t can fit into the tool s, 11s, and the front portion can be fixed to the bracket 13. The upper opening of the housing part,
The slits 11s and the protrusion 14 of the lid cover 14 are manufactured with a shape that can close the space formed between the left and right handle frames 7, 7.
t, 14t, and said bracket 1
Bolt with knob 1 for nut 15 attached to 3.
6 are screwed together through a hole 14h formed in the lid cover 14 to be fixedly attached.

Also, the meter panel 11 on the rear surface of the sheet metal material 11
a includes switches 18 for automatically controlling the plowing depth by raising and lowering the tail wheel 17 of the rotary tillage device R, a key switch 19, and an auxiliary gear shift lever 2;
0. A so-called defrot lever 21 is provided for setting a differential gear (not shown) housed in the transmission case 2 into a functional state or a non-functional state.

[Another example]

In addition to the embodiments described above, the present invention may also be configured such that, for example, a sheet metal material is connected to the left and right handle frames by welding.
