Description

[Detailed explanation of the invention] (a) Industrial application field This invention is suitable for use in places where areas where grass or weeds are allowed to grow are adjacent to areas where they should not be grown (for example, golf courses). To provide a device for cutting the border between a vegetated part and a non-vegetated part in a bunker, a ridge part of a field, etc., to prevent grass, etc. from protruding into areas where it should not be vegetated and growing thickly.

(b) Conventional technology In places where grass grows around a sand pit (an area where grass should not grow), such as bunkers on a golf course, if the grass is not properly maintained, the grass around the sand pit will grow into vines. Since the grass grows in the sandbox and becomes obsolete, it is necessary to take measures to prevent the grass from entering the sandpit. Although it is often necessary to repeat the process, at present most of the work of cutting the edges of the grass to stop the grass from growing into the sandbox is done manually.

In addition, recently, crop cultivation fields such as rice paddies are often left fallow and then replanted, so weeds that grow in the ridges when left fallow can be found in areas within the field (areas where weeds should not grow). ), and the weeds that have spread within the field are raked into the tilled soil during tillage for replanting.

(c) Problems that the invention aims to solve When cutting the edges of bunkers on golf courses, as mentioned above, most of the work was done by hand, which had the disadvantage of extremely low work efficiency and high management costs. In addition, when replanting a fallow field, weeds that have entered the field from the ridges are raked into the tilled soil. There was a problem in that the soil conditions in the central part of the field were different, resulting in uneven crop growth throughout the field.

Therefore, the present invention enables labor-saving and efficient work such as cutting edges around bunkers on golf courses and removing weeds along the ridges of idle fields, and also removes grass and weeds that have been separated by edge cutting. This was carried out with the aim of providing a device that allows for more convenient work by levitating layers on the surface of the soil.

(d) Means for Solving the Problems In order to achieve the above-mentioned object, the turf vegetation edge cutting device of the present invention has a turf edging device attached to one shaft end of the rotary shaft 4 that protrudes left and right from the drive case 1. At the same time, an edge cutting blade 10 for vertically cutting the hairline is attached, and the soil mixed with rhizomes separated by the edge cutting blade 10 is removed from the cut portion on the rotating shaft between the edge cutting blade 10 and the drive case 1. Equipped with a feed rotor A having a function of horizontally feeding in a direction away from the soil, and using a rotating shaft 4 on the other side of the drive case 1 to scrape up rhizomes mixed in the soil and separate them into layers on the surface of the soil. It is assumed that a separation rotor B is equipped.

(E) Effect According to the device of the present invention having the above-mentioned configuration, the self-propelled vehicle body is moved while operating the rotary shaft 4 by aligning the edge cutting blade 10 along the grass line of a bunker or the edge of a field ridge. By moving forward, the edge cutting blade 10 cuts the boundary between the area with vegetation such as grass and the non-vegetation area.
is cut vertically, rhizomes that invade the bunker from the vegetation are separated, and the soil mixed with rhizomes is transferred to the feed rotor A located inside the edge cutting blade 10.
The material is then laterally fed in a direction away from the cut portion.

After the cutting and transverse feeding are completed, the self-propelled vehicle body is turned to the return path, and the separating rotor B provided on the other side of the rotating shaft 4 is moved to remove the rhizomes mixed with the rhizomes that have been transversely fed as described above. If the self-propelled vehicle moves while adapting to the soil, separation rotor B will cause
The soil containing rhizomes is stirred in a direction perpendicular to the axis of the separation rotor B, and the rhizomes mixed in the soil are scraped up and separated into layers on the surface of the soil. Therefore, by using the device of the present invention, it is possible to cut off grass, etc. in a reciprocating operation, separate and separate the separated rhizomes on the surface of the soil, and make them easy to remove. It is possible to perform edge cutting with high efficiency and neatness.

(f) Examples Examples of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing the main structure of an embodiment of the device of the present invention, and shows the main parts of the working vehicle shown in FIG.
It is an enlarged view taken along a line.

1 in the figure is a drive case, which houses a transmission mechanism linked to the engine 3 of the self-propelled vehicle body 2, supports a rotating shaft 4 projecting left and right at its lower end, and supports the rotating shaft 4.
It can be driven by the transmission mechanism.

In addition, in the self-propelled vehicle body 2 of the embodiment, the running wheels 6 are fitted to the drive axle 5 installed at the lower part of the running transmission, and the drive case 1 is installed diagonally downward at the rear of the running wheels. The drive case 1 is constructed as a rear-mounted type in which the control handle 7 is extended rearward on the upper part of the drive case 1, but there are also cases in which the drive case 1 is mounted in the front and installed in the front part of the running wheels. In some cases, the rotary shaft is of a vehicle working type that is commonly used.

An edge cutting blade 10 is attached to one shaft end of a rotating shaft 4 that protrudes left and right from the drive case 1 to vertically cut the boundary between a part 8 where grass is grown and a part 9 where no grass is allowed to grow. The soil mixed with rhizomes separated by the edge cutting blade 10 is placed between the edge cutting blade 10 and the drive case 1 inward in the axial direction of the rotating shaft, that is, from the cut surface by the edge cutting blade 10. A feed rotor A is equipped to move horizontally in the direction of separation, and a rotary shaft 4 on the other side of the drive case 1 is equipped with a rotary shaft 4 that stirs the soil containing rhizomes and scrapes up the rhizomes mixed in the soil. A separation rotor B that separates the layers on the surface is equipped.

As the edge cutting blade 10, a disc blade whose outer peripheral edge is a blade, that is, a well-known coulter (vertical disc blade) or the like is used.

In addition, as for the feed rotor A, as shown in the figure, conveyor claws 14 having a twisted structure for laterally conveying the excavated soil are inserted into brackets 13 arranged at intervals on the shaft tube 12. It is sufficient to use a type that is attached to the plow or a generally known screw plow or rotary plow.

Furthermore, the illustrated separation rotor B has stirring claws 19 . Bracket 1 of shaft cylinder 17 to be fixed with
It is equipped with 8 parts.

This separation rotor B stirs the soil mixed with rhizomes such as grass or weeds in a direction perpendicular to the axis of the rotating shaft, scrapes up the rhizomes mixed in the soil, and removes them from the surface of the soil. In addition to the one shown in the figure, it can be constructed using a flower-shaped rotor, a regular claw, etc.

The upper part of the separating rotor B is covered with a cover, and a protective gear 20 is provided at the outer end of the separating rotor B to prevent rhizomes and the like from scattering laterally and outwardly.

When the self-propelled vehicle is a vehicle working type, the protective gear 20 and the edge cutting blade 10 also serve as a gauge for setting the working depth.

Therefore, when working with the edge cutting device configured as described above, the edge cutting blade 10
If the self-propelled vehicle body 2 is moved in the direction of arrow A as shown in FIG.
Cuts vertically along the boundary, from vegetated area 8 to non-vegetated area 9
Cut off the rhizomes of grass that are invading the lawn.

Then, the soil mixed with rhizomes separated from the turf vegetation 8 is moved away from the cut portion by the lateral feeding action of the feed rotor A installed inside the edge cutting blade 10 (in the direction of the drive case). The object is moved sideways (in the direction in which it approaches).

When such cutting and traversing processes are completed, the self-propelled vehicle body 2 is turned in the return direction B, and the separating rotor B is placed in the soil mixed with rhizomes that has been traversed as described above (see Fig. 6). If the self-propelled vehicle body is moved accordingly, the rhizomes mixed in the soil will be rotated by the raking blades of the separation rotor B, that is, the stirring claw 19 in the example diagram. The soil is raked up in a direction perpendicular to the axis of the shaft and separated into layers at the soil surface.

(g) Effects of the invention As described above, the device for cutting edges of grass, etc. according to the invention cuts the hairline of grass, etc. vertically on one shaft end of the rotary shaft 4 that protrudes left and right from the drive case 1. The edge cutting blade 10 to be cut is attached, and the soil mixed with rhizomes separated by the edge cutting blade 10 is fed horizontally to the rotating shaft between the edge cutting blade 10 and the drive case 1 in a direction away from the cut portion. Equipped with a feeding rotor A having a function, and on the rotating shaft 4 on the other side of the drive case 1,
Since it is equipped with a separation rotor B that scrapes up rhizomes mixed in the soil and separates them into layers on the surface of the soil, grass and other vegetation can be grown by reciprocating a self-propelled vehicle equipped with this device. The border between one part and another part can be trimmed in an orderly manner, and the work can be carried out mechanically and efficiently.

Moreover, since the cut rhizomes generated during the treatment are separated and layered on the surface of the soil by the separating rotor B, the rhizomes can be easily removed and the non-vegetated areas can be cleaned easily. Furthermore, during work, the balance between the feed rotor A and the separation rotor B allows the machine to maintain good straightness.
