Abstract

A machine suitable for use in spreading and laying a seed mursery strip, especially, a lawn nursery strip over the ground is equipped with means for spreading and laying the seed nursery strip over the ground; means for firming the thus-laid seed nursery strip; and means for clawing the top soil of the ground in front of the spreading and laying means and then evenly sprinkling the thus-clawed top soil as top dressing soil over the thus-firmed seed nursery strip. The seed nursery strip can thus be automatically and stably spread and laid even if they have somewhat weak tensile strength and at the same time, top dressing soil can be applied over the thus-laid nursery strips.

Claims

1. A soil laminating machine for applying a seed nursery strip of flat, prefabricated webbing material between soil layers, comprising a main body having attached thereto:

means for spreading and laying at least one seed nursery strip onto the ground;

means for compressively flattening across the thus-spread and laid seed nursery strip;

tiller means for clawing, lifting, and throwing the topsoil of the ground in a rearward direction onto the seed nursery strip, said tiller means positioned in front of the spreading and laying means, whereby even sprinkling of the thus clawed, lifted and thrown topsoil as a top dressing soil over the compressively flattened seed nursery strip will be attained,

means for adjusting the operating depth of the tilling means relative to the ground so that the thickness of the dressing soil can be controlled to be within a range of from 1 mm to 2 cm and said means for adjusting is composed of at least one gauge wheel and a height-adjusting bar connecting the gauge wheel to the main body and,

wherein the tiller means is composed of a multiplicity of claws provided on a rotary shaft, and means rotating the rotary shaft in a direction opposite to the direction the gauge wheel rotates.

2. A soil laminating machine as claimed in claim 1, wherein the gauge wheel is disposed in front of the tiller means.

3. A laminating machine as claimed in claim 1, wherein said at least one seed nursery strip is in a rolled form, and the spreading and laying means is a shaft which extends in a direction perpendicular to the travelling direction of the laminating machine and is attached pivotally and detachably to the main body of the laminating machine by an attaching means so that in operation, the rolled nursery strip is fit on the shaft and is then paid out from the shaft.

4. A laminating machine as claimed in claim 1, wherein the means for compressively flattening is a roller connected pivotally by a connecting means to the main body of the laminating machine.

5. A laminating machine as claimed in claim 1, wherein the laminating machine further comprises a water sprinkler, whereby to sprinkle water to the thus-laid seed nursery strip.
