DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for winding up a lawn grown in a mat shape and then rewinding the lawn to spread the lawn on the ground.

[0002]

2. Description of the Related Art After growing a lawn, soil is put on a net-like rug, sowed with a lawn seed, and the lawn is grown in a mat shape so that it is easy to collect and transplant the grass to another place. rear,
The present applicant has considered a technique of winding the rug and collecting the lawn and transplanting it to another place. Also, a technique has been disclosed in which a base is made of fine bark flakes, and a lawn is grown on the base to form a mat (Japanese Patent Application Laid-Open No. 53-750).
No. 35).

[0003]

However, merely supporting the wound lawn on the apparatus requires the unwinding operation to be performed manually, which is troublesome.
It is also conceivable that gears are provided at both ends of the winding shaft and the winding shaft is rotated by a motor. However, the apparatus becomes complicated and large in size due to the motor and the gears.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and when unwinding and paving a wound lawn, there is no need to provide a motor and it is not necessary to rely on human power. It is intended to provide a device.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and is provided with a mat-like lawn wound thereon. A roller, a central roller provided in parallel with the center of both side rollers and supported by a spring, a wheel for supporting the device, and a rotation transmission mechanism for transmitting the rotation of the wheel to the side roller to unwind the lawn, It is characterized by having.

[0006]

When the apparatus is moved, the rotation of the wheels is transmitted to the side rollers by the rotation transmitting mechanism, and the rotation of the side rollers rotates the wound lawn to unwind.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. The apparatus of the present embodiment has two pairs of plate-shaped main frames 1. Each pair of main frames 1 has wheels 3 between them and rotatably supports an axle 5 therethrough.
Immediately above the axle 5, a side roller 7 is supported by the main frame 1 in contact therewith. By contacting as described above, the side roller 7 rotates in a direction opposite to the rotation direction of the axle 5.

A central roller 9 is disposed at the center of the two side rollers 7 provided in this manner. The central roller 9 is parallel to the side roller 7 and is supported by a torsion bar 11 having a spring function.
That is, a pair of torsion bars 11 are provided at both ends of the central roller 9. Each torsion bar 11 has a U-shape, and one side of the U-shape is fixed to the main frame 1 substantially in parallel with the central roller 9. The other side of the U-shape is fixed to the support bracket 13. The center roller 9 is rotatably supported by the support fitting 13. Therefore, when the weight of the lawn 15 is added to the center roller 9, the upper and lower sides of the torsion bar 11 are twisted and elastically support the center roller 9 by acting as a spring.

A handle 17 is provided on the main frame 1 so that an operator can move the device by pushing or pulling the device.

The operation of this embodiment will be described below.
The mat-like lawn 5 is wound around the winding core 19,
It is placed on the side roller 7 and the center roller 9. The take-up core 19 has a presser 21 and is a mat-like lawn 1.
5 is held down. A steel pipe 23 is provided at the center of the winding core 19, and the entire lawn 15 can be lifted through the steel pipe 23 through a pipe or the like, or can be mounted on the apparatus of the present embodiment.

When the operator moves the device to the right in the figure, the wheels 3 rotate clockwise. The side roller 7 in contact with the axle 5 of the wheel 3 rotates counterclockwise. The grass 15 wound by the rotation of the side rollers 7
Rotates clockwise. This rotation is performed smoothly by the central roller 9 elastically supporting the lawn 15 from below. The tip of the lawn 15 that rotates clockwise is unwound in the moving direction of the device, that is, to the left in the figure, and is laid on the ground.

By moving the apparatus in this manner, the side rollers 7 rotate and unwind the lawn 15 almost automatically, so that there is no need for an operator to unwind the lawn 15 manually. Therefore, if the worker moves the apparatus by simply pulling the handle 17, the lawn 15 can be contracted.

In the above embodiment, the spring supporting the central guide roller 9 is the torsion bar 11, but in other embodiments, it may be a coil spring or a leaf spring.

In the above embodiment, the rotation transmitting mechanism for transmitting the rotation of the wheel 3 to the side roller 7 is constituted by the side roller 7 contacting the axle 5 in the axial direction. In the example, gears may be provided at both ends of the axle 5 and the side rollers 7, and these gears may mesh to form a rotation transmission mechanism.

[0015]

As described above, according to the lawn laying device of the present invention, when the device is moved, the rotation of the wheels is transmitted to the side rollers, and the wound lawn is rotated and automatically wound. Since the unwinding is performed, the unwinding and laying of the lawn can be performed almost automatically without providing a motor.
