[0002]

2. Description of the Related Art The present applicant has already considered a device for putting soil on a net-like rug, sowing lawn seeds, and winding up a lawn grown in a mat shape. A device that performs this winding by a motor is also considered. Furthermore, a device that folds and collects a mat-like lawn is being considered. In this way, by collecting, transporting, and laying the mat-like lawn as it is, a large amount of lawn can be handled at a time, and a natural lawn with good appearance without gaps can be transplanted.

[0003] As a net-like rug, a lawn growing net having nails on the back side is used, and the action of the nails does not cause the lawn and the lawn growing net to be displaced on the seedbed for growing or the transplanted ground. It is conceivable to do so.

[0004]

However, it has been difficult to take in the lawn grown on the lawn growing net with the claws with an ordinary drum. That is, the catching becomes unstable due to the claws, and there is a possibility that the lawn is shifted left and right with respect to the drum.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a mat-like lawn capable of stably taking in a mat-like lawn grown on a lawn growing net with claws. It is an object of the present invention to provide a collection device.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and is intended to provide a mat-like lawn grown on a lawn growing net which is driven to rotate and has a claw on a back surface. It is provided with a take-up drum for taking in while supporting, and a diagonal braided net is provided on the outer peripheral surface of the take-up drum, and the diagonal braided net is supported from the inside by a support drum having a projection group of a foamed rubber material. Features.

[0007]

When the lawn grown on the lawn growing net is taken in with the drum, the claws on the back surface of the lawn growing net enter the mesh of the oblique braided net and are securely locked in the direction of taking in. Due to this locking, the lawn growing net and the lawn do not shift left and right with respect to the drum. Then, the diagonal braided net is supported from the inside by the protruding portion of the support drum, and takes in the lawn softly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. The vehicle body 1 has a U-shape with an open front. Further, it has four wheels 3, and the wheels 3 can be rotated and moved by the moving power mechanism 5 via the gear 7. The moving direction can be changed by a steering mechanism (not shown).

A frame 9 is provided on the vehicle body 1. The frame 9 includes two columns 9A and beams 9B protruding from the columns 9A. At the tip of the beam 9B, a pair of take-in drums 11 is provided. One of them is a driving drum 11A, which is driven to rotate by a take-in driving device 13 via a chain 15 and a sprocket 17. The other is a driven drum 11B, and both drums 11A, 11B
The lawn 19 is sandwiched between them.

The lawn 19 is grown on a lawn growing net 21. A claw 23 is provided on the back of the lawn growing net 21.
(FIG. 3) is provided, so that it is hard to be displaced in the seedbed or the transplanted ground.

The drive drum 11A is a take-in drum of the present embodiment, and has a diagonal braided net 2 made of vinyl chloride on its outer peripheral surface.
5 are arranged. The oblique braided net 25 has a bias knitting shape, and one mesh has a rhombus shape in the taking-in direction. A support drum 27 is provided inside the oblique braided net 25. The support drum 27 is made of a foamed rubber material, and a large number of protrusions 29 are formed integrally radially. A depression 30 is formed at the tip of each projection 29, and it is easy to support the mesh of the oblique braided net 25 without causing slippage. This foamed rubber is a closed-cell rubber.

Inside the support drum 27 is another foam material 31.
And is supported by a protective tube 33 made of vinyl chloride. Inside the protective tube 33, another foam material 35 is provided.
And is supported by a metal shaft protection tube 37.
A rotation shaft 39 is provided inside the shaft protection tube 37.

On the side surface of the drive drum 11A, there is provided a disk-shaped panel 43 for pressing the side surface. This panel 4
The outer shape of 3 is larger than the outer shape of the diagonal braided net 25 and can support both ends of the lawn 19. This can prevent the lawn 19 from being shifted left and right from the drive drum 11A and the mud attached to the lawn 19 from scattering in the left and right direction.

A claw 45 is formed on the surface of the driven drum 11B, so that the lawn 19 can be taken in without slipping the lawn 19 without damaging the surface.

A turning pin 47 is provided on the side surface of the beam 9B, and turns the turning rod 49. Two rotating rods 49 are provided, and a pair of folding rollers 51 are provided to extend over the lower end. The folding roller 51 guides the grass 19 taken in and swings it forward and backward. It also has the function of an equalizer that prevents unnecessary tension from acting on the lawn 19.
At the upper ends of the two rotating rods 49, a hydraulic cylinder, which is an actuator 55 for performing rotation, is provided via a shank 53. However, the actuator 55 may be an air cylinder or another electric type.

The vehicle body 1 has a U-shape, and the U-shaped opening faces forward, and a bogie 57 is connected to this opening. The cart 57 is for receiving the lawn 19 to be folded, and when the lawn 19 is full, it is replaced with the next cart 57. This trolley 57
In order to prevent the collapse of the folded lawn 19, a basket 59 can be provided. The cart 57 is provided with a handle 61, which can be manually separated from the vehicle body 1 when the lawn 19 is full.
A bumper 62 made of rubber or the like is attached to the tip of the U-shaped portion of the cart 1.

The moving power mechanism 5 is provided with a lever 63 for performing an operation. A control switch panel 65 is provided near these levers 63 so that the actuator 55 and the take-in driving device 13 can be controlled.

The operation of this embodiment will be described below. Lawn 1
First, the end of the lawn 19 is connected to the drive drum 1
1A and the driven drum 11B, and the folding roller 5
It is guided to the trolley 57 throughout 1 interval. A part of the carriage 57 may be provided with a presser that presses the end of the lawn 19.

In this state, the vehicle body 1 moves toward the lawn 19 by the moving power mechanism 5. At the same time, the take-in driving device 13 drives the driving drum 11A to rotate. As a result, the grass 19 is taken in without a large tension being applied. At this time, the mat-like lawn 19 is taken in together with the lawn growing net 21. And the lawn growing net 2
The claws 23 on the back side of 1 enter the rhombic mesh of the oblique braided net 25. For this reason, the back surface of the lawn growing net 21 can be in close contact with the oblique braided net 25 of the drive drum 11A, and the claws 23 are locked in the mesh. Therefore, the lawn 19 does not shift with respect to the drive drum 11A in the left-right direction, that is, in the axial direction.

Further, since the lawn 19 is supported by the group of projections 29 made of foamed rubber through the diagonal braided net 25, the lawn 19 is taken in softly without applying excessive force.

The driven drum 11B is connected to the driving drum 11A.
And the claw 45 of the driven drum 11B is made to enter the mesh of the oblique braided net 25 of the drive drum 11A,
The entrainment of the driven drum 11B with respect to the driving drum 11A can be improved. Also, the claw 4 of the driven drum 11B
5 also makes the grass 19 at the time of capture stable.

At the same time as this loading, the actuator 5
5, the rotating rod 49 slowly rotates, and the folding roller 51 slowly swings forward and backward. Therefore,
The lawn 19 guided by the folding roller 51 is also
Swung forward and backward. With this swinging motion,
The lawn 19 is folded over.

When the basket 59 is filled with the folded lawn 19, the operator holds the handle 61 and disconnects the bogie 57 from the vehicle body 1 and replaces it with another bogie 57.

As described above, according to the present embodiment,
The mat-like lawn 19 is taken in by the driving drum 11 </ b> A and is folded by the folding roller 51. Therefore, compared to the case where the lawn 19 is wound up and taken in, the driving drum 11
The rotation speed of A does not change, and stable capture is performed.

Furthermore, according to the present embodiment, the claws 23 enter the mesh of the diagonal braided net 25 of the driving drum 11A on the back surface of the lawn growing net 21 for growing the mat-shaped lawn 19, so that the stable take-in is possible. Can be done. In addition, even a normal mat-like lawn having no claws 23 can be similarly taken in.

Further, a projection 29 for supporting the oblique braided net 25
The group is made of a foamed rubber material as described above, and is soft,
Support each independently. Therefore, when a large force is momentarily applied to the mat-like lawn 19 taken in, the entire diagonal braided net 25 moves softly while being supported by the projections 29, and absorbs the force. Therefore, it is possible to prevent the lawn 19 from being damaged by a large force.
At the same time, generation of noise can be prevented. When a local force is applied to the lawn 19, the local diagonal braided net 25
The projection 29 that supports is bent, and the displacement is locally performed, thereby releasing the force. Therefore, it is possible to prevent a large force from being locally applied to the lawn.

In addition, the projections 29 can not only be displaced in the radial direction to release the force, but can also be displaced in the circumferential direction and the axial direction to release the force. That is, each of the projections 29 can be bent in the form of swinging the head back and forth and right and left at the same time as the height of the back is reduced, and can be displaced in the circumferential direction, that is, the taking-in direction and the axial direction. Therefore, the force applied in these directions is released, and the diagonal braided net 25, the lawn growing net 21, and the mat-like lawn 19 can be softly supported. be able to.

Also, the lawn 19 is more suitable for preservation of the lawn 19 because the gap is formed between the folded and the air flow is better than when the lawn 19 is wound up. Further, if the basket 57 and the like are provided on the cart 57 and the lawn 19 is folded high upward, a large amount of lawn 19 can be stored upward while keeping the horizontal space the same. Therefore, storage space can be saved.

The folding roller 51 is connected to the rotating rod 49.
Since the swinging width in the forward and rearward directions can be made sufficiently large by increasing the length of the rotating rod 49, the folding operation can be easily performed on the large basket 59. it can.

In the above-described embodiment, the take-in driving device 13 rotates the driving drum 11A by the chain 15 and the sprocket 17, but in other embodiments, a gear group or a belt and a pulley are used. May be.

The moving power mechanism 5 and the take-in driving device 1
3 can use various types of power such as a gasoline engine, an electric motor, or a hydraulic motor.

In the case where the actuator 55 is a hydraulic cylinder or an air cylinder, the device for generating the pressure may be the same as the take-in driving device 13 or may generate the pressure by another device. good.

[0033]

As described above, according to the mat-like lawn collection device of the present invention, the claws provided on the back surface of the lawn-growing net on which the mat-like lawn has been grown have the meshes of the diagonal braided net. It locks firmly, so that the grass for growing grass and grass are not shifted left and right with respect to the capture drum when capturing.
Stable import work can be performed.

The diagonal braided net is supported from the inside by a group of projections made of a foamed rubber material, so that a mat-like lawn and a lawn growing net can be taken in softly, there is little noise, and the grass roots are disturbed. It is less likely to be damaged or damaged.
