2. Description of the Related Art Conventionally, in order to transplant a lawn to a reclaimed land, a lawn was cut from the turf seedbed and carried, and then transplanted, but with such a method, peeling from the turf seedbed,
A lot of manpower was required for transportation and planting. The weight of the lawn for transplantation was also heavy. Therefore, in order to solve such a problem, as disclosed in Japanese Patent Publication No. 50-21373, a flexible mesh structure is laid on a film,
A solution such as lengthening the lawn for transplantation has been attempted by growing lawn on the grass and entwining the lawn roots with a mesh structure. However, with this method, the mesh structure remains after being transplanted, and as a result, the mesh structure is exposed by being caught by a bird or the like, and there is a problem that the grass is peeled off by being caught on a person's foot or the like. . Therefore, as a method for preventing foreign matters such as a mesh structure from remaining after transplantation, as disclosed in Japanese Patent Application Laid-Open No. 53-75035 and Japanese Patent Application No. 2-272978, grass entangled with bark flakes. A method has been developed to grow a carpet of grass for transplantation formed by the roots of.

In order to produce a turf nursery for growing such a carpet-like lawn for transplantation, JP-A-53-7 is used.
Japanese Patent No. 5035 discloses a bark crushing device, a mixing device for turf seeds / bark flakes, etc., and a turf nursery laying machine.
Further, in Japanese Utility Model Laid-Open No. 5-48648, a support rack for film rolls is mounted on a frame supported by a pair of front and rear support rollers, and a film laying roller for feeding the film from the rolls on the support rack and laying the film on the ground. A hopper that receives and stores a mixture of grass seeds, bark flakes, etc., and an impeller that is built into the bottom of this hopper and that discharges a fixed amount of a mixture of grass seed bark flakes and other materials in synchronization with the rotation of the support roller. And a laying unit characterized by being provided with a laying gutter for spraying the discharged matter on a laid film, and a towing vehicle capable of hoisting and towing the laying unit. A characteristic turf nursery laying machine is disclosed.

[0004]

However, the turf nursery laying machine described in JP-A-53-75035 described above is
In addition to the large machine itself, the turning radius is also large, so when used in a limited section such as fallow land scattered within the cultivated land, as in Japan, the utilization rate of the cultivated land is very small. Was becoming. Further, this turf nursery laying machine was difficult to prepare when the laying direction was bent during film laying.

Therefore, the turf nursery laying machine disclosed in Japanese Patent Laid-Open No. 53-75035 is separated into a turf nursery laying part and a turf nursery laying part using a wire to cultivate the land. In order to improve maneuverability and work efficiency, improvements have been made such as towing by winders installed at the front and rear ends of the machine. As a result, the utilization rate of cultivated land was improved, but the work efficiency was not always sufficient. Also, the film was torn.

[0006] Therefore, further, a mixing tank for the grass seed bark flakes and the like is placed on a chassis that can be self-propelled on an endless track, and a grass seedbed laying part is held on the side of the chassis so that it can be raised and lowered. We have developed a machine equipped with a screw conveyor that conveys a mixture of thin pieces of turf seed bark from the bottom of the mixing tank for thin pieces to the hopper of the above-mentioned part for laying the grass seedbed. However, when this machine was used, the utilization efficiency and work efficiency of the cultivated land were certainly improved, but it was difficult to swivel smoothly, so it was difficult to prepare when the laid film was bent in the direction. Met.

In order to solve such a problem, the inventor of the present invention, as disclosed in Japanese Utility Model Laid-Open No. 5-48648, attaches to a mount supported by a pair of front and rear support rollers.
A support rack for a roll of film, a film laying roller that rolls out the film from the roll on the support rack and lays it on the ground, a hopper that receives and stores a mixture of grass seeds and bark flakes, and a turf that is built in at the bottom of this hopper. An impeller that discharges a fixed amount of a mixture of seed bark thin pieces and the like in synchronization with the rotation of the support roller, and a laying gutter that sprays the discharged matter on the laid film are provided. We have developed a turf nursery laying machine that is characterized by a laying unit that is characterized by: and a towing vehicle that can lift and tow this laying unit. Since only the nursery can be laid,
When lawn carpets of various sizes were cut out in accordance with orders after growing lawns into products, the amount of the remaining portion was large and the product yield was low. In addition, the work efficiency of laying a turf nursery was not sufficient.

Further, in order to solve such a problem, the inventor of the present invention, as disclosed in Japanese Patent Application No. 4-72457, has a front end portion pivotally supported on a self-propelled vehicle and its pedestal and a rear portion. A storage tank such as bark flakes that can be lifted and lowered, a conveyor provided at the bottom of the storage tank, a film roll support rack provided below the storage tank, and a film fed from the film roll of the support rack with pores. Needle roller to open, laying roller to lay the film on the ground, turf seed disperser and fertilizer disperser provided at the upper rear end of the storage tank, below the rear end of the storage tank inside A winged roller that has a stirring blade and rotates at the bottom in synchronism with the wheels of a self-propelled vehicle to send out material such as turf seedlings, and the rotation of the rollers causes the material such as turf seedbeds to be laid on a film oscillated back and forth. Laying laying From a hopper that has a gutter, a device that detects the level of material such as grass seedbed in the hopper and controls the start / stop of the conveyor at the bottom of the storage tank, and a roller that rolls the material such as the laid grass seedbed. We have developed a laying machine for turf nurseries, etc. However, if the film is laid wider than the width of the left and right wheels of the self-propelled vehicle, the film laid on the marks of the tires of the wheels does not always adhere to the ground and may be stripped from the ground by wind after installation. It was In addition to the film laying, the laying gutter vibrates back and forth in synchronism with the wheels of the self-propelled vehicle.Therefore, especially at the start, etc., a material such as a lawn nursery with a certain thickness is always laid on the film. It was not always done. Furthermore, especially at high speeds, the fertilizer and turf seeds may not be sufficiently mixed with the bark flakes. The problem to be solved by the present invention is to solve such a problem.

[0009]

In order to solve these problems, the present inventor has proposed a medium such as a self-propelled vehicle, a bark slice or the like having a front end portion pivotally supported on its pedestal and a rear portion capable of moving up and down. Storage tank, a conveyor provided at the bottom of the storage tank, a film roll support rack provided below the storage tank, a needle roller for making pores in the film fed from the film roll of the support rack, the storage tank A hopper provided below the rear end of the hopper, a seed spraying device such as turf provided above the hopper, and a chemical spraying device such as fertilizer, and a stirring blade inside the hopper. A stirring tank, a roller for laying a film provided below the stirring tank, a mixture of a medium, seeds and a drug on the film laid on the lower end of the stirring tank while reciprocating back and forth.
A laying trough for laying the obtained nursery bed material to a certain thickness, and a turf nursery bed laying machine including a roller for rolling the seedbed material provided behind the laying trough. , Seed
The child spraying device and the chemical spraying device are respectively provided in the front and rear above the hopper and are horizontally long and have a hopper-shaped storage tank having a width substantially the same as that of the hopper, a conveyor roller built in the bottom thereof, and a horizontal row at the bottom thereof. Laying a film consisting of 8 to 16 discharge holes, a mechanism for opening and closing the discharge holes and adjusting the opening thereof, and a hose for supplying seeds or medicine discharged from each discharge hole to the hopper. The first roller has a large diameter and the same diameter as the roller for rolling the seedbed material (hereinafter referred to as "second rolling roller").
We have developed a laying machine for turf nursery beds, which is a compaction roller and is characterized by reciprocating a laying gutter using the rotational movement of a first compaction roller and a second compaction roller.

In the present invention, a storage tank means a bark thin piece or the like.
The medium is temporarily stored, and has an input port at the top and an output port at the rear. In addition, it is preferable that a door or the like that slides up and down is provided at the rear discharge port so that the opening can be adjusted. This storage tank was loaded so that the front end portion was pivotally supported and the rear portion could be moved up and down because the first rolling roller and the second roller below the rear end portion of the storage tank that is grounded when a nursery bed such as grass is laid. This is so that the compaction roller can be lifted together with the rear part of the storage tank, moved away from the ground, and moved to another place. Further, the conveyor provided at the bottom of the storage tank is for introducing the medium inside the storage tank from the discharge port at the rear portion into the opening portion at the upper part of the hopper. Normally, the power of the conveyor is transmitted from the power of the engine through a clutch and a transmission. Furthermore, by detecting the level of the seedbed <br/> materials in the hopper by a sensor provided in the hopper, it is preferable to control the start and stop of the conveyor.

On the other hand, the film forming the bottom surface of the laid seedbed is pulled out from the film roll mounted on the support rack provided in front of the hopper below the storage tank, and the pores are opened by the needle roller, The first compaction roller having the same diameter as the second compaction roller and having a large diameter and heavy is laid on the ground and strongly compacted so as to be in close contact with the ground. On the other hand, when the medium is put into the hopper by the conveyor, the seed spraying device and
From chemical spray unit, uniformly seeds and drug <br/> at a constant rate of addition is sprayed, Ru is mixed by the stirring blade of the stirring tank. That
The seedbed material obtained as a mixture of these is delivered to a constant thickness on the film laid on the ground by the laying gutter provided at the bottom of the hopper. Then, the upper surface of the second roller is pressed by the second roller so as to make the surface even.

The seed dispersal device and the chemical dispersal device in the present invention are respectively a hopper-shaped storage tank having a horizontally long and substantially the same width as the hopper, which are arranged in the front and rear above the hopper.
Conveyor rollers built in the bottom, 8 to 16 discharge holes provided in a horizontal row at the bottom, a mechanism for opening and closing the discharge holes and adjusting the opening thereof, and discharge from each discharge hole. It was made seeds or agent from the hose to be supplied to the hopper, respectively, seeds or agent in the hopper-like reservoir,
By adjusting the rotation speed of the conveyor roller and the opening of the discharge hole, the addition speed is adjusted to a constant value.
The six hoses allow the medium in the hopper to be widely sprayed in the lateral direction so that they can be uniformly mixed in the stirring tank in a short time, and can withstand high-speed operation.
As the mechanism for opening and closing the discharge hole and adjusting the opening, a sluice valve that opens and closes only at the adjusted opening, such as a sluice that can be used for both opening and closing and opening adjustment, may be used. It is also possible to separately provide a mechanism for adjusting the opening degree such as the above and a mechanism for opening and closing such as the sluice valve. Further, when the conveyor at the bottom of the storage tank is stopped and the supply of the medium to the hopper is stopped, it is preferable that the conveyor rollers of the seed spraying device and the chemical spraying device are automatically stopped so that the discharge hole is closed.
Further, in this seed spraying device, if grass flower seeds are used instead of grass seeds, the turf nursery bed laying machine according to the present invention can also be used for laying flower flower seed beds.

The laying gutter according to the present invention is to lay the seedbed material uniformly on the film in a constant thickness while reciprocating back and forth. The reciprocating motion of this laying gutter is to not only lay it uniformly to a constant thickness, but also to lay flat bark slices in the nursery material horizontally. The power of this reciprocating motion in the present invention utilizes the rotational motion of the first pressure roller and the second pressure roller. Normally, the rotational movement of the first pressure roller and the second pressure roller is reduced by rotation of chains provided by gears having the same number of teeth provided on the same side surface of the first pressure roller and the second pressure roller, respectively. It is transmitted via a gear by another chain to an impeller that reciprocates the laying gutter. The laying gutter normally reciprocates by being pushed outward by the rotation of the impeller only when it comes into contact with the wing of the impeller, and by being pulled inward by the spring in the wingless part of the impeller. However, the present invention is not necessarily limited to this method, and a cam mechanism, a crank mechanism or the like may be used to change the rotational movement into a reciprocating movement.

[0014]

In the laying machine for turf nursery beds according to the present invention, since the roller for laying the film is the first rolling roller having the same diameter as the second rolling roller for rolling the nursery material, the film is heavy. , It is strongly compressed to the ground and adheres to the ground so that there is no risk of being stripped from the ground by wind after installation. Also, laying the gutter is so reciprocated by utilizing the rotational movement of the first compacting roller and a second compacting roller, seedlings
The flooring material is automatically laid on top of the film when it is laid, and stopped when the film is laid down. Further, the seed dispersal device and the chemical dispersal device are respectively a horizontally long hopper-shaped storage tank having substantially the same width as the hopper, a conveyor roller built in the bottom portion, 8 to 16 discharge holes provided in a horizontal row at the bottom, A mechanism for opening and closing the discharge holes and adjusting the opening thereof, and 8 to 8 extending from each discharge hole.
Since it consists of 16 hoses, seeds and medicines
