Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an axle type working machine for performing ground work while propelling a machine body with a rotary working tool mounted on a traveling axle.

[0002]

2. Description of the Related Art Since an axle type working machine is small and lightweight, it tends to dash due to the operation of a rotary working tool that also functions as a traveling function. The rod is attached, and the work of running is carried out while restraining the dash of the aircraft by the resistance effect.

[0003]

Although the conventional means for restraining the dash of the fuselage with the resistance rod attached to the tail portion of the fuselage has the advantage of a simple structure, the pilot artificially places the resistance rod in the field. Since it is necessary to adjust the applied resistance by performing an operation to press it, it is difficult to adjust the applied resistance force, the operator's burden is heavy, and the resistance rod advances in the field after the work, and the resistance is further increased. There was a problem that the finished state of the work was significantly irregular because the sticks were entangled with grass straw and the like.

[0004]

SUMMARY OF THE INVENTION The present invention has been implemented for the purpose of solving the above-mentioned problems, and a rotating work tool is attached to a traveling axle (10) provided laterally below a mission case (2). In an axle type working machine equipped with (A) and performing ground work while propelling the machine body with the rotating work tool (A), a dash suppressing tool that is rotationally driven in the opposite direction to the rotating work tool (A). It is characterized in that (B) is provided. Further, it is preferable that the dash suppressing tool (B) is provided as a part of the rotary working tool (A).

[0005]

In the axle type working machine according to the present invention, the rotary working tool (A) mounted on the traveling axle (10) is used to perform the ground work while the machine body is propelled while performing the ground work. Since the dash depressing tool (B), which is rotationally driven in the opposite direction to the tool (A), properly prevents the dash from being dashed by the operation of the rotating work tool (A), it is small and lightweight. Despite being an axle-type work machine, good ground work can be performed without a dash. And since it does not rely on the resistance rod, the operator does not need to adjust the resistance rod artificially to the field, which reduces the burden on the operator, and the resistance rod advances in the field after work, and The resistance rod will not be entangled with grass straw, etc., and the ground work can be done in good condition.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a side view of an axle type working machine according to the present invention, FIG. 2 is a front view of the same axle type working machine, and FIG. [FIG. 3] is a transmission cross-sectional view of a main part.

1 to 3, (1) is an engine,
(2) is a mission case, (3) is a fender, (4) is a steering wheel, (5) is a bumper, (6) is a rear hitch,
These make up the body of the axle type working machine.
Also, (7) is the throttle lever, and (8) is the clutch lever.
Is.

The engine (1) is directly mounted on the upper part of the transmission case (2), and its output part is accommodated in the mission case (2) via a main clutch (centrifugal clutch, etc.). 9) interlockingly connected, traveling transmission mechanism
(9) is adapted to rotationally drive a traveling axle (10) horizontally and horizontally bearing-mounted on a lower portion of the mission case (2).

The traveling axle (10) is a transmission case (2).
It is provided so as to project to the left and right from the above, and the rotary working tool (A) is detachably attached to the projecting portion, and ground work is performed while propelling the machine body by the rotary working tool (A). The rotary working tool (A) has a plowing claw (12) of an appropriate shape on the outer periphery of a cylinder shaft (11) fitted on the traveling axle (10) and wedged.
The groups are arranged, and a gauge wheel (13) for setting the working depth is provided at the outer end of the cylinder shaft (11).

However, when ground work is performed while propelling the machine body by the rotating work tool (A), the rotating work tool is used.
The operation of (A) tends to dash the machine body. Therefore, in order to prevent the machine body from dashing, in the present invention, dash prevention is rotationally driven in the opposite direction with respect to the rotating work tool (A). The tool (B) is provided, and a specific example thereof is shown in FIG.

In FIG. 3, the dash restraint tool (B) penetrates the traveling axle (10) in the central portion and the mission case (2).
A base body (14) fixed to the side of the base body, an outer body (15) which is located outside the base body (14) and is supported by the traveling axle (10) in a freely rotating state, and a base body (14) ) And an outer body (15), and a reverse drive mechanism housed and housed in the case, and a dash suppressing tilling claw (16) attached to the outer periphery of the outer body (15). .

The reverse drive mechanism includes a drive gear (17) fixed to the traveling axle (10), an idle gear (18) meshing with the drive gear (17), and an intermediate gear meshing with the idle gear (18).
(19) and a final gear (20) that meshes with the intermediate gear (19) and is idle supported on the traveling axle. The final gear (20)
Is meshed with a passive gear (21) formed in the outer body (15), and the outer body (15), that is, the dash suppressing tillage claw (16) attached to the outer body (15), is rotated. ) Plowing claws
It is driven to rotate in the opposite direction to (12).

The rotary work tool (A) and the dash suppressing tool
(B) means that the aircraft propulsion force by the rotating work implement (A) is set to be larger than the propulsion inhibiting force by the dash restraint implement (B), and the dash restraint implement (B) suppresses the dash of the aircraft. The rotating work implement (A) is provided in such a manner that the machine body is properly propelled. Specifically, the rotating work implement (A) has a working width larger than that of the dash restraining implement. Cultivating claw (12) of work implement (A) and dash deterrent
(B) The shape of the tilling claw (16) is made different, or the rotating work tool (A) is used by an appropriate means such as setting the rotation of the dash restraint tool (B) to be slower than that of the rotating work tool (A). Propulsion> The relationship of propulsion deterrent by the dash deterrent (B) is revealed.

Further, the axle type working machine shown in the embodiment is of a type having no side clutch in the transmission system for the traveling axle, but the present invention is a side clutch in the transmission system for the traveling axle. Needless to say, the present invention can be applied to an axle type working machine of a type that has the above-mentioned type, and can also be applied to a type in which a transmission system to a traveling axle is configured to be switchable between forward and backward movement. Also, the tilling claw attached to the dash deterrent device may be a bidirectional one.

The reverse drive mechanism for rotationally driving the dash restraining tool (B) is not limited to the specific example shown in FIG. Any other modified structure may be used as long as it can drive the restraining tool (B) in the opposite direction. Further, in the illustrated embodiment, both the rotary working tool (A) and the dash restraining tool (B) are configured to rotate about the horizontal axis, but in some cases, the dash restraining tool (B). To
A dash depressing tiller claw (16) attached to the dash deterrent tool (B) is supported on the soil directly below the mission case (2) by tilting it downward at a certain angle with respect to the horizontal axis. It can also be configured to be driven into and to perform residual tillage treatment.

Reference numeral (22) in FIG. 3 denotes a detachable cover which can be attached and fixed so as to cover the outside of the dash restraint device (B), and the cover (22) is rotated. Working tool (A)
This is for covering the dash restraint tool (B) from which the tilling claw (16) has been removed when the traveling axle (10) from which is removed is equipped with traveling wheels (not shown) and the vehicle travels on the road.
