FIG. 2 shows an example of the bb section of FIG. The lawn 16, the first support portion 18, and the arm 26 are not shown.

In FIG. 2, the lawn split comb 14 has two protrusions 14a extending in the width direction in front of the small roller 20 and perpendicular to the traveling direction. The protrusion 14a is
The turf divided by the tip portion 14b of the turf dividing comb 14 is prevented from being caught inside the two small rollers 20. Thus, the cutter 24 prevents the grass from being cut in multiple layers and damaging the lawn.

FIG. 3 shows another example of the bb section of FIG. The lawn 16, the first support portion 18, and the arm 26 are not shown.

The lawn splitting comb 141 is formed wider toward the rear side over the interval between the small rollers 20. The lawn split comb 141 prevents the lawn from being caught inside the two small rollers 20. Thus, the cutter 24 prevents the grass from being cut in multiple layers and damaging the lawn.

FIG. 4 is a front view showing still another example of the turf dividing comb as seen from the direction of arrow a in FIG. Turf split comb 142
Has a narrow width downward, and is preferably used for separating and aligning grass from its root. Press the aligned turf with the small roller 20, and insert the cutter 2 between them.
Cut at 4. Thereby, cutting of the grass can be minimized and damage to the lawn can be suppressed.

FIG. 5 shows another example of a state near the cutter 24 as seen from the direction of arrow c in FIG. It should be noted that the second support portion 28 and the discharge port 38 are omitted in the drawing for the sake of clarity.

The claw portion 301 is composed of two plows 30b and a wide hoof-shaped claw portion 301a attached to the lower surface thereof.
The wide hoof-shaped claw portion 301a can stably support the plow 30b. The lawn 16a and the lawn 16b are both cut by a cutter 24. One example of dimensions is turf 1.

m, 70 mm. Height j when raising the turf 16b
Is about 70 mm.

6 to 8 show an example of the process (construction) of blowing powdered compost onto the lawn according to the present invention.

FIG. 6 is a cross-sectional view showing an example of lawn before construction. Height g of grass 16a and depth h of grass root 16b
Are 40 mm and 30 mm, respectively.

FIG. 7 is a cross-sectional view showing an example of lawn under construction. Powder compost 3 in the gap below the cut grass 16
Are accumulated. Interval k between cut turf 16 when raised
Is, for example, 40 to 50 mm. The ridge width 1 of the turf 16 is, for example, 200 mm, and in this case, the lengths l ₁ and l ₂ from the center of the ridge width 1 to both ends are both 100 mm.

FIG. 8 is a cross-sectional view showing an example of the lawn after the operation. The lawn 16 is shaped flat by laying the powdery compost 3 below it. The distance m between the turf 16 after shaping is, for example, about 10 mm.

FIG. 9 is a schematic rear view showing an example of the blower 1 according to the present invention. Note that the curing shower 44 and the roller 48 are not shown for clarity.

In FIG. 9, three blowing units 1
0 is attached to the tractor 5. Unit 10
Is equipped with seven sets of cutters, claws (not shown), a blowing pipe 36, and the like. That is, the blow pipe 36
Each of these is a piano keyboard and can be moved independently. To give an example of dimensions, the overall width n of the blower
Is, for example, 5.6 m. In this case, the width p of one blowing unit 10 and the interval q of the blowing unit 10 are 1.8 m and 0.1 m, respectively.

[0051]

According to the present invention, the lawn fertilizer blowing machine cuts and lifts the lawn, and the fertilizer is blown under the lifted lawn. Therefore, the fertilizer such as powder compost directly under the lawn. Can be given. Therefore, the pollution of water quality can be suppressed as compared with the case where the fertilizer is sprayed on the surface.

Further, when the grass is aligned with a comb, the grass roots can be cut without cutting the grass in multiple layers. Therefore, it is possible to prevent the grass from being damaged by cutting.

Further, if the comb is supported by the supporting portion provided with the roller and the elastic member so as to be movable according to the shape of the lawn, the comb can be lifted and dealt with when the height of the lawn is not uniform. . In this case, it is possible to prevent the grass from being disturbed by cutting the grass in multiple layers by suppressing the grass by the rollers.

Further, if the cutter is supported by the supporting portion including the elastic member so as to be movable according to the shape of the soil under the lawn, the ground of the soil under the lawn is not uniform and there are rocks. If there is a tree root, the cutter can be lifted to handle it.

The present invention is not limited to the above-mentioned embodiments. The number of cutters, blowing pipes, etc. is arbitrary. The number of blowing units attached to the vehicle is also arbitrary.
