Abstract

PROBLEM TO BE SOLVED: To provide a method and apparatus for producing a turf for vegetation wound into a roll shape, resisting to washing with water even if the peeled thickness is thin, hardly causing damage of the turf under preservation, facilitating the plantation operation on a ground or the like, hardly bringing various bacteria in, and enabling the turf to grow well. SOLUTION: This method for producing the turf for the vegetation wound into the roll shape comprises peeling the turf for the vegetation from a root part into a long sheet shape or peeling the turf from a sheet part, removing attached soil therefrom, and winding the resultant turf into the roll shape. The turf is obtained by spreading a net on a field in which the grass grows properly or on the roots of grass present in the field, growing the grass in the presence of the net so that the roots will entangle with the net, and cutting the roots at the lower surface side of the net. The apparatus for producing the turf for the vegetation wound into the roll shape is obtained by attaching a cutting blade 7 for vertically cutting the turf in a cutting width direction, and a horizontal peeling blade 8 arranged at a depth for peeling the turf to the front part of a pulled or self-traveling carriage, installing a water-washing device 4 in the rear part of the blades, and further installing a winding device 5 at the rear part of the water-washing device 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for producing a roll grass for vegetation for rolling a lawn grown in a field or the like for use.

[0002]

2. Description of the Related Art Conventionally, lawns grown in fields or the like have been cut out to a predetermined rectangular standard and used for planting. Recently, a method of implanting by cutting into a long strip is being tried. Conventionally, as a cutting device for transplanting grass that has been proposed to cut into a long strip, a rotary grass cutting device (Actual Kaihei 6-17413), that is, a cutting blade wound in an oval shape ( The saw blade) rotates in the left-right (right angle) direction with respect to the traveling direction, and at the bottom of the saw blade frame,
A device has been proposed in which the lower surface and side portions of the grass are cut to separate the grass from the ground and cut it. In addition, a device for stripping grass in a strip shape by moving the grass stripping blade forward and backward while cutting is also in practical use. In order to solve the difficulties of these devices, the present inventor also previously applied for a patent application 2001-281.
336 proposes a lawn stripping device.

[0003]

[Problems to be Solved by the Invention] Cutting out a lawn cultivated in a field or the like into a long strip shape has been proposed previously.
The lawn stripping device of 01-281336 has made this possible efficiently, but there is no suitable method and device for producing vegetative roll turf for making a preferable roll wrapping in preparation for using band turf. I can't see it. Therefore, even if the stripping thickness is thin, it can withstand washing with water, has less damage to the lawn during storage, can be easily planted on the ground, etc., does not bring in bacteria, and has good lawn growth. The method and equipment were studied.

[0004]

[Means for Solving the Problems] As a result of studying the above problems, the grown vegetation grass is stripped from the root portion into a long sheet shape or peeled from the sheet portion, which is rolled. This is the method of manufacturing roll turf for vegetation. The vegetation grass cultivated by the cultivating soil or at least the cultivating soil in which the sheet is arranged below is peeled off from the root part or peeled from the sheet part, and the adhered soil is removed from this, and the roll is passed without or after washing with water. I decided to roll it. In this method for producing rolled turf grass for vegetation, it is preferable to peel off two rows of turf having a stripping width of 1 m width or 50 cm width at one time in consideration of usability at the time of construction. By peeling off in this way, the lawn upholstery work is easy to design and the efficiency is improved.

In the roll winding of the lawn, a paper tube, bamboo or a synthetic resin hollow tube or a bar material is used as a core material, or a cord material is used as a core material and the cord material stretched in the width direction of the roll winding grass is used. If both ends are long and the turf roll has a predetermined diameter,
You may use both ends of a string as a fastening string which fastens the outer periphery of a lawn.

For the roll winding of the turf, the previously patented patent No.
No. 2783756, No. 2997447 proposed, deploy the net on the grass field existing in the field or field where the grass is growing properly, and grow until the grass root is entangled with the net in the presence of the net Therefore, the one in which the root is cut off on the lower surface side of the net is preferable because it has strength when washed with water.

When it is prohibited to bring cultivated soil to the construction site or to reduce the weight, it is preferable to remove the soil by shaking or brushing before or after washing with water. The vibration is to shake the belt-shaped turf to drop the soil, and as the vibration means, a vibrator, a vibrator, a repeated hitting rod, or the like can be adopted.

[0008] For the purpose of prolonging the storage of turf, eliminating miscellaneous bacteria to the construction site, or improving the integrity of turf, sterilization may be performed during or after water washing. As a bactericide for sterilization treatment, chlorhexidine hydrochloride, Irgasan DP-300, benzethonium chloride, chlordane, alcohol-based drugs and components contained in essential oil of moon peach, citronellal, carvone, geraniol, thymol have antibacterial activity. , D-camphor has an insect repellent action, eugenol has an antibacterial action among components contained in clove oil, and hinokitiol and tsuyopsene have an antibacterial action among components contained in hiba oil. A bactericide that combines four types of essential oils is also suitable. Furthermore, the use of water containing several ppm of ethylene gas, ozone gas, ethylene oxide gas, chlorine gas, etc. also has a bactericidal action.

Further, it is preferable to add a water retention agent before winding the roll for the purpose of keeping the turf moisturized during storage and growing. As the water retention agent, JP-A-3-86803 describes a water-absorbent resin formulation, and such a water-absorbent resin formulation is sowed or applied to a runner, and then water is sprayed to retain the water. You should let me. There are three types of water-absorbent resins, starch-based, cellulose-based, and synthetic polymer-based, which are selected according to their use. For example, the synthetic polymer type includes polyacrylate type, polyvinyl alcohol type, polyacrylamide type, and polyoxyethylene type. Japanese Patent Application Laid-Open No. 7-99832 discloses a structure obtained by curing carboxymethyl cellulose and a water-soluble polyvalent metal salt such as a copper salt, an aluminum salt and an iron salt.
No. 74897 discloses a medium for plant cultivation, which comprises one or more aqueous gel-forming raw materials selected from sodium alginate, carboxymethylcellulose and peritin, which does not require heating.
(Water supply material) is described, but this can also be used. Soluble phosphorus fertilizer, silicic acid fertilizer, lignocellulose / humic acid, nitrohumic acid and the like can be added as a soil improving agent. Furthermore, as a plant activator, glucose, vitamins,
Hormonal agents and the like may be added. Depending on the substance, these may be dispersed in powder or liquid form depending on the substance and held.

The vegetation roll winding turf manufacturing apparatus of the present invention has a structure in which a trolley that can be towed or self-propelled is provided with a water washing device and a winding device behind it. The towing can be performed by a working machine such as a tractor used in the field.

Assemble a cutting blade that cuts the lawn vertically in the cutting width direction to the front of the trolley that can be towed or self-propelled, and a substantially horizontal stripping blade that is arranged at the stripping depth of the lawn, and move to the rear of it. It was also used as a vegetation roll turf manufacturing device provided with a water washing device and a winding device behind it. It is possible to perform stripping, washing with water, and winding with the same device while running.

In such a vegetation roll roll turf production apparatus, if a vibrating soil removal device or a brushing soil removal device is provided in front of the water washing device, the soil can be removed before the water washing, thus saving water. The efficiency of soil removal is improved. The vibrating soil removing device has a structure in which the top or bottom surface of the grass cut out in a strip shape is tapped or shaken while a tapping rod having a return spring is reciprocated by a crank, a cam, a cylinder, a solenoid, or the like. The brushing soil removal device removes soil from the bottom surface of the lawn cut into strips by contact polishing with a brush having a large number of metal wires or synthetic resin filaments.

The water washing device is a device in which water drops dropped or jetted from a large number of nozzles are cut out in strips from above to below,
Alternatively, the structure is such that the turf is ejected toward the runner.
The wash water may be re-supplied by a line that constitutes a circulation system for reuse.

The above-mentioned sterilizing agent may be contained in the washing water, or a sterilizing agent spraying device may be provided behind the water washing device. A water retention agent, fertilizer, and other growth-promoting agent addition devices are installed in the rear, and a winding device is installed in the rear.
