Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a mower and is intended to provide a mower that is inexpensive and can easily perform root cutting or boring work.

[Problems to be solved by the prior art and device] The mower is mounted on the lower part of the abdomen of a tractor, etc., with the cutting blade device along the cutting ground, while maintaining a constant height above the ground. Promote the lawn mowing work.

At this time, gauge wheels are provided at the front and rear of the mower to keep the mower deck at a constant height. In addition, it is known that in the grass, the growth of the grass is improved by sending air into the ground. For this reason, conventionally, a soil piercing operation has been performed using a dedicated renovator (see, for example, Japanese Utility Model Publication No. 39-5842).

However, preparing a dedicated renovator in this way has the drawback of increasing the cost, and has the drawback that the lawn mowing work and the lawn root cutting work or boring work cannot be performed at the same time.

[Means for Solving Problems] Therefore, the present invention proposes to solve the above problems, and has taken the following technical means.

That is, cylindrical support members 8 for supporting the gauge wheel 9 are fixedly provided on the rear left and right ends of the mower deck 4 which covers the outer circumferences of the plurality of cutting blades, and the spikes 2 are attached to the support members 8.
The mower is characterized in that the mounting shaft 13 having the attached roll 12 or the mounting shaft 13 having the disk-shaped cutting blade 3 is detachably mounted.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.
First, the structure will be described. The mowing device 1 includes a plurality of mowing blades (not shown) and a mower deck 4 that covers the outer periphery thereof. A transmission case 5 is fixed to the center of the upper surface of the mower deck 4. An input shaft 6 is mounted on the front portion of the shaft 5 so as to project therefrom. Rotational power extracted from the power output shaft of the tractor is interlocked with the input shaft 6 via a universal joint or the like.

Brackets 8 and 8 as cylindrical support members having vertical shaft holes are fixedly provided at both left and right end portions of a frame portion 7 formed on the rear upper surface of the mower deck 4. The mounting shaft 10 of the gauge wheel 9 that supports the rear part of the mower deck 4 is inserted so that it can be vertically attached and detached. Reference numeral 11 is a gauge wheel that supports the front portion of the mower deck 4. Normally, the bracket 8,
Although the lawn mowing work is performed by inserting the mounting shaft 10 of the gauge wheel 9 into the roll 8, when performing the root cutting of the lawn or the punching of the lawn, as shown in FIG. 2 or the roll 12 shown in FIG. The disc-shaped cutting blade 3 is mounted in place of the gauge wheel 9.

A plurality of spikes 2 are radially arranged on the outer peripheral surface of the roll 12, and cantilever-shaped fork-shaped brackets 14, 14 are attached to the left and right ends of the roll 12, respectively.
Mounting shafts 13, 13 are fixed to the upper surface of 4. The mounting shafts 13, 13 are composed of shafts having the same diameter as the mounting shaft 9 of the gauge wheel 9, and are fixed by being inserted into the brackets 8, 8 supporting the gauge wheel 9 from below.

In this embodiment, the roll 12 is hollow, and a water injection hole 15 is provided at a side end thereof as shown in FIG. 4, and water is introduced from there to adjust the weight of the roll 12. During the work, the roll 12 has a function as a gauge wheel that rolls in contact with the ground to prevent the mower deck 4 from sinking.

The cutting blade 3 shown in FIG. 5 is arranged along the shaft 16 and
Gauge wheels 17 having a diameter smaller than the diameter of the cutting blade 3 are provided at both left and right ends of the bracket 6, brats 14 and 14 are fixed thereto, and mounting shafts 13 and 13 are fixed to the brackets 14 and 14.

In the above example, when the machine body is advanced while rotating the rotating parts, the grass is cut off by the cutting blades in the mower deck 4, and the grass is discharged from the grass outlet provided in the mower deck 4, thus Lawn mowing work is performed.

When performing lawn cutting or turf hole drilling simultaneously with lawn mowing, the gauge wheel 9 attached to the mower deck 4 is removed, and the spikes 2 are attached to the brackets 8 and 8 supporting the gauge wheel 9. The mounting shafts 13 and 13 supporting the rolls 12 provided with are attached or the mounting shafts 13 and 13 supporting the cutting blade 3 are inserted.

When the aircraft is advanced in this state, the spikes 2 or the cutting blades 3 are stabbed or cut into the ground to a predetermined depth, and air enters the soil surface through these cut openings to expand the soil surface. In addition to making it soft, turf can be well grown by air injection.

[Advantage of the Invention] As described above, the present invention is provided with the cylindrical support members 8 for supporting the gauge wheel 9 fixedly provided on the rear left and right ends of the mower deck 4 which covers the outer circumferences of the plurality of cutting blades. Mounting shaft 13 having roll 12 with spikes 2 on support member 8
Alternatively, since the mounting shaft 13 having the disc-shaped cutting blade 3 is detachably attached, not only the work of lawn mowing alone, but also the work of lawn mowing and root cutting of lawn, or the work of lawn mowing and boring. They can be performed simultaneously, and work efficiency is significantly improved.

Further, since it is not necessary to purchase a machine dedicated to root cutting and punching, and the roll 12 or the cutting blade 3 can be attached / detached and replaced using the same support member 8, the replacement work becomes easy, The number of parts can also be reduced, the configuration becomes simple,
The manufacturing cost of the device can be reduced.
