Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a walking type mobile agricultural machine such as a small management machine having a handle that can be folded and stored.

[0002]

2. Description of the Related Art Generally, a walking-type mobile agricultural machine such as a small-sized management machine has a handle at the rear of the machine. This type of handle extends obliquely upward from the rear of the fuselage and obstructs the storage and transport of the fuselage.Therefore, it is required that the handle be foldable. There is a strong demand for small management machines that may be transported by hand.

[0003]

However, in the prior art described above, the handle is folded forward so that it follows the upper part of the fuselage, or the handle is folded downward and is also used as a stand. The actual situation was that it protruded from the fuselage to expand the storage capacity of the fuselage. Further, in the above-described configuration, it is necessary to support the folded handle at the retracted position. However, conventionally, a dedicated support member is provided to support the folded handle. There was an inconvenience that caused complication.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve these problems in view of the above circumstances, and has an axle for providing wheels on both right and left sides of an airframe. On the other hand, in a walking-type mobile agricultural machine having a bifurcated handle projecting obliquely upward at the rear of the fuselage, the handle is configured to be freely foldable forward and backward, and the handle is folded forward and stored. The tip is located near a wheel or an axle. In other words, the folded handle can be stored so as to overlap the fuselage in side view without protruding up and down of the fuselage. And the transportability can be improved. Further, the tip of the stored handle is located inside the wheel. That is, the folded handle does not protrude to the left and right of the wheel to expand the storage capacity of the body, and as a result, the storage capacity of the body when the handle is stored can be further reduced. Further, the tip of the stored handle is supported by an axle or a rotary claw provided on the axle. That is, since the axle or the rotary claw portion is also used as the support member of the folded handle, a dedicated support member is not required, and the number of parts can be reduced and the structure can be simplified.

[0005]

Next, one embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a walk-behind management machine. The walk-behind management machine 1 includes a transmission case 2 inclined forward and rearward and high, an engine frame 3 provided at an intermediate portion of the transmission case 2, and a transmission. Hitch frame 4 provided at the rear of case 2 and handle frame 5 provided at the top of transmission case 2
And On the engine frame 3, the engine 6,
A fuel tank 7 and a muffler 8 are provided, and an output of the engine 6 is input to an upper portion of the transmission case 2 via a transmission belt (not shown) in a belt cover 9.
Various work machines can be mounted on the hitch frame 4, and the resistance bar 10 is mounted during the tilling operation. Resistance rod 1
0 is mounted so as to protrude downward from the hitch frame 4 and interferes with the cultivated soil during tilling work so that the running of the machine body 1a is moderately braked. Functions as a regulating stand.

[0006] An axle 11 protruding to the left and right sides is mounted in a lower part of the transmission case 2 in a penetrating manner. Engine power input to the upper part of the transmission case 2 is transmitted to the axle 11 via a transmission mechanism and a transmission chain (not shown), and wheels (rotor discs) 12 mounted on the tip of the axle 11 are driven to rotate. . In addition, axle 1
A plurality of rotary claws 13 are mounted on an intermediate portion of the rotary shaft 1, and the rotary claws 13 plow a field as the axle 11 rotates.

A handle 14 extending diagonally upward is provided at the tip of the handle frame 5. Handle 1
Numeral 4 is formed in a forked shape (U-shape), and a grip 15 for an operator to grip is provided at the left and right end portions. The left-right width (left-right grip width) of the tip of the handle 14 is set wider than the left-right width of the engine frame 3 and narrower than the left-right space of the wheels 12. The proximal end of the handle 14 is supported by the distal end of the handle frame 5 so as to be able to rotate back and forth, and the range of rotation is regulated by a bolt 16 with a grip. Bolt with handle 16
, Always keeps the tightened state, and fixes the handle 14 at a predetermined height. When you loosen the bolt 16 with the grip,
Vertical rotation of the handle 14 is allowed in a predetermined range, and the height of the handle 14 can be adjusted according to the height of the operator. When the bolt 16 with grip is removed,
The rotation of the handle 14 exceeding the adjustment range is allowed,
When the handle 14 is largely turned forward, the handle 14 is stored in a folded state. The handle bolt 1 is welded to the base end of the handle 14.
The rotation of the handle 14 is restricted by penetrating the tip end of the handle frame 5 in the left-right direction. Further, the bolt through hole of the handle frame 5 or the handle bracket 14a is formed into an arc-shaped long hole so that the handle 14
Height adjustment is possible.

As described above, when the handle 14 is turned forward in a folded state, the handle 14 is stored along the left and right sides of the body 1a. At this time, handle 14
Is located near the inner side of the wheel 12 and the axle 1
1 or the rotary pawl 13. That is, the folded handle 14 is not allowed to be stored so as to overlap with the body 1a in a side view without protruding above and below the body 1a, and is positioned inside the wheels 12 so that the body 1
There is no large overhang on the left and right of a. This makes it possible to minimize the body storage volume when the handle is stored.

In the walking type management machine 1 constructed as described above, the axle 11 for providing the wheels 12 protrudes on both left and right sides of the body 1a, while the axle 11 is provided obliquely upward at the rear of the body 1a. It comprises a protruding bifurcated handle 14. The handle 14 is configured to be foldable back and forth, and the tip of the handle 14 folded forward and stored is located near the wheel 12 or the axle 11. Therefore, the folded handle 14 is attached to the body 1a.
Can be stored so as to overlap with the fuselage 1a in side view without protruding up and down, and as a result, the storage volume of the fuselage when the handle is stored is reduced, and the storage and transportability of the fuselage 1a are improved. be able to.

[0010] Further, since the tip of the stored handle 14 is located inside the wheel 12, the folded handle 14 does not protrude to the left and right of the wheel 12 to expand the storage volume of the body 1a. As a result, the body storage volume when the handle is stored can be further reduced.

Further, since the tip of the stored handle 14 is supported by the axle 11 or the rotary pawl 13,
Handle 1 with axle 11 or rotary pawl 13 folded
4 can also be used as the support member, and as a result, a dedicated support member is not required, and the number of parts can be reduced and the structure can be simplified.
