DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the production of turf seedlings in which upholstered turf is cut to produce turf seedlings of a gull-shaped turf in order to save labor in turf creation by planting and sowing turf. Related to the device.

[0002]

2. Description of the Related Art There are two types of lawn creation methods: seed propagation and vegetative propagation. The latter method is generally used when using reed-type turfgrass such as blackgrass, nosiba, and bermudagrass. It is a target. In particular, it is difficult to produce seeds practically in the rice plant, and the development is based only on vegetative propagation. Vegetable turf vegetative propagation methods can be classified into two types based on the shape of the turf seedling: a method using upholstered grass and a method using loosened stalks. The method using upholstered grass is a certain standard (14 × 36cm or 28 × 36c
m, the total thickness is about 2 cm), and the turf seedlings (the seedlings themselves are also referred to as “upholstery”) are laid on the base.
Cover the soil with a thickness of cm and roll with a roller. Usually, a method of providing a gap (joint) between the seedlings (joining method) is employed. In this case, the lawn is completed in a relatively short period of time (about two months), and this method is adopted for general lawn development. However, the aging stalks and undegraded dead plants (thatch) contained in the upholstery are brought directly to the land, which requires time and effort to manage after completion and maintain the turf for a long time. Is also relatively difficult.

[0003] As a method using a loosened broom, there are a planting lawn and a sowing lawn. In the planting lawn method, the loosened turf is loosened or cut into smaller pieces and planted in strips or stumps. In the case of row planting, the width of the row is 10-2
It is said that it is desirable to set the height to 0 cm and to set the spacing between the strains to 10 to 15 cm in planting. In the sowing lawn method, the loosened turf is further cut into pieces of 3 to 8 cm, sprayed on a base, covered with soil to a thickness of 2 to 3 cm, and applied with compaction. In the planting lawn and sowing lawn method, it takes time to manufacture and plant turf seedlings, and the time required to complete the lawn is two to three times longer than in the case of the upholstered lawn method. However, these methods are rarely adopted. However, it is possible to renovate the crest and improve the soil environment in the rooting area, so that a dense and stable lawn can be produced. For this reason, in lawn production areas, planting lawn and sowing lawn are commonly performed. Looking at the production stage of turf seedlings in each construction method, mechanization has already been achieved with the upholstered turf method, but at present the planting turf method and sowing turf method rely on manual work.

[0004]

Conventionally, the work of cutting loosely in the turf seedling production stage of planted turf and sow turf relies on manual work because the stalks are complicatedly entangled. For this reason, the "unraveling" cutting work was labor-intensive, took a lot of work time, and was not efficient. The reason for such manual work is that it was thought that if the "relaxation" work was performed mechanically, it would be impossible for rooting and sprouting to occur even after turf development. No mechanical device has been built to achieve the desired conditions. SUMMARY OF THE INVENTION An object of the present invention is to improve the efficiency of production by making it possible to mechanically produce turf seedlings of a turfgrass, and to improve the rate of rooting and germination of turf seedlings.

[0005]

A turf seedling manufacturing apparatus according to the present invention is provided with a pair of upper and lower rotary cylinders at an outlet side of a guide member for guiding the transport of the upholstered turf, and the upholstered turf fed out from between the pair of rotary cylinders. A flywheel-type cutter for cutting the turf seedlings is provided, and a spring means for flipping the cut turf seedlings in a predetermined direction is provided on the outer peripheral portion of the cutter means.

[0006]

According to the above-mentioned turf seedling manufacturing apparatus, the length of the upholstered turf is adjusted to a desired length by adjusting the transporting speed of the upholstered turf by the transporting means, or by adjusting the number of cutting blades of the cutter means and the rotation speed. In addition to cutting the turf seedlings in a short time, the efficiency of turf seedling production is improved without damaging the roots of the turf seedlings.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a turf seedling manufacturing apparatus will be described with reference to FIGS. In order to spread the turf of the crest-type turf grass in a planar manner and transport it, a guide member 1 for guiding the transport may be provided, and a belt conveyor or the like may be provided on the transport surface of the guide member 1. A pair of upper and lower rotary cylinders 2 that are rotated by a driving device are provided on the outlet side of the guide member 1, and their rotation axes are arranged in parallel with the plane of the guide member 1, and a turf is placed between the upper and lower rotary cylinders 2. It can be sent out horizontally. Since the rotary cylinder 2 is cylindrical, the guide member 1 is provided so as to extend to near the top of the lower rotary cylinder, and the support base 3 is provided at the outlet side of the upper and lower rotary cylinders 2.
Is provided so that the stretched turf that is sent out can be supported horizontally.

A fly-hole type cutter means 4 is provided on the outlet side of the support base 3, and a vertical rotating plate 4a is provided on the upper surface of the support base 3 with an appropriate number of cutting blades 4b. The center shaft is driven at an appropriate rotation speed by adjusting the gear ratio of the driving device. The cutting blade 4b is rotated in a direction substantially perpendicular to the upholstery on the support base 3, and the upholstery is rotated by, for example, 10 to 28 mm.
It can be cut to length one after another. Further, blades 5 are provided on the outer peripheral portion of the rotating plate 4a, so that the lawn seedlings that have been cut and dropped downward are flipped up in a predetermined direction. In the present embodiment, the cut turf seedlings are put into the guide tube 6 and discharged to a predetermined position.

Next, an embodiment in which turf seedlings are manufactured using the turf seedling manufacturing apparatus will be described. As a turf seedling production apparatus actually used, an apparatus obtained by improving a flyhole type forage harvester MFH3510 manufactured by Star Agricultural Machinery Co., Ltd. was used. That is, the mower part of the forage harvester was removed, and a stainless steel guide member 1 of 35 × 80 cm was separately attached to the material charging section. In this case, similarly to the above-described apparatus, the turf is sent out from the pair of cylinders at a substantially right angle to the cutting blade and cut by the cutter means, and the turf seedling cut by the blower is flipped up in a predetermined direction. Turf seedlings were manufactured.

In the forage harvester, the cutting size of the turf is cut into various sizes of 5 mm to 30 mm by adjusting the feed speed of the upholstery and the rotation speed of the cutting blade. Investigated. Upholstery 3
The time required for adjusting zero seedlings to seedlings was 40 to 120 seconds irrespective of the cutting size, which was a significant reduction in time as compared with the case where the upholstery was loosened manually. In addition, when the cutting size of the turf seedling is smaller than 10 mm, the stalk is too loosened, and when the cutting size is larger than 30 mm,
This was not desirable due to insufficient loosening of the fork.

The quality survey of turf seedlings was carried out on 10, 14, 20, 2
A fixed amount of turf seedling of each cutting size of 8 mm was measured and divided into a portion where root emergence was possible and a portion where root emergence was impossible according to the appearance, and the dry weight of each was measured. The measurement result is
As shown in FIG. 3, the dry weight of the portion where root emergence is possible is as high as 70 to 80% of the whole, and it can be seen that there is almost no problem in using for turf construction.

[0012] In order to confirm that the rooting and germination sites of the seedlings having a cut size of 10 to 28 mm were not fatally damaged by the cutter and blower, a rooting and germination test was performed on the crested stem. For this purpose, moistened filter paper was placed in a petri dish, and spikes randomly picked from a portion of the seedling where rooting and sprouting were possible were sprinkled.
Approximately 70-80% of the buds showed root emergence in about a week. Therefore, it was confirmed that the fornix stalk which was determined to be capable of root emergence on the appearance was not damaged by the preparation method of the present invention.

[0013]

According to the claw-type turfgrass manufacturing apparatus of the present invention, upholstery can be cut mechanically, so that the efficiency of turf seedling production is improved and labor-intensive manual work can be released. In addition, even if the turf seedling is produced by mechanical cutting, the ratio of rooting and germination is 70% or more, so that the turf is of sufficient quality for turf construction.
