Grass Seed Sowing Groove Opening Device And Seeding Machine

The present invention relates to a seeding groove forming mechanism for making a seeding furrow for sowing grass seeds in a golf course or other grass field, and a seeding machine having the seeding groove forming mechanism.

In particular, in response to the rotary blade plate for ground cutting, the seeding groove expansion and seed input rotary plate that provides a grass seed input path to the inside of the expanded sowing groove as well as the expansion of the seeding groove cut by the rotary blade plate for ground cutting The provision of the sieve makes it possible to easily expand the grass seed sowing groove even on hard grass ground (soil) and to insert the grass seed accurately into the sowing groove. It is about a seeding groove forming device and a seeding machine.

In general, it is widely known that golf courses or various turf fields continuously sow turf seeds using a turf planter for the purpose of extending the lifespan of the turf surface by improving the turf quality.

In the case of Korea, too, the useful life of the grass surface is increased by at least 10 months by over-sowing the cold-season grass on the warm-season grass by the sowing machine. These planters are disclosed in the following patent documents.

Patent Document 1, which the present applicant has previously applied for and is currently receiving registration, is 'The grass seed planter includes a seeding groove (furrow) installation part (Slicer) that forms a grass seed sowing groove, a seeding groove expansion part, a seeding part, and a rolling (Rolling) ) and a stopper unit integrally, so that the seeding groove installation work, the seeding groove expansion work, the seeding work, and the rolling and stopper work can be continuously and simultaneously performed, and the depth of the seeding groove by the stopper unit is constantly maintained. In addition, by the balance maintenance part, the existing grass is not pressed down even during overeding of grass seeds in an uneven ground.'

Patent Document 2 discloses that 'When forming a groove (furrow) in the ground such as no-till soil, residues, weeds, soil, etc. of previous crops adhere to the substrate, do not damage the base, or impede the smooth rotation of the rotating part, and the groove at high speed Provided are a groove opening mechanism capable of forming A groove opening mechanism that forms a groove in the soil while moving in the moving direction. A single disk coulter that rotates during movement and forms a cut-in in the vertical direction with respect to the ground surface with a blade tip installed on the outer periphery; , provided at the rear of the disc coulter with respect to the traveling direction and provided with a wide part that widens the groove cut by the disc coulter, the wide part is on the front side of the disc coulter, in a direction from the disc coulter side to the rear As a result, it has a tapered widening member.'

Patent Document 3 discloses that the present invention relates to a planter, 'In a planter in which a seeding unit connected to a rice transplanter and receiving power from the rice transplanter to supply seeds and a seeding unit for sowing seeds are simultaneously operated, connected to the PTO device of the rice transplanter PTO shaft to which power is input; Gearbox connected to and interlocked with the PTO shaft; a second shaft connected to the gearbox and rotated interlockingly; a seeding shaft connected to the second shaft and rotated interlockingly while rotating the seeding cup to sow seeds; And it provides a seeding machine including a seeding shaft connected to the second shaft to rotate interlockingly while rotating the seeding cup to supply seeds to the seeding cup.'

However, among the prior art, the sowing machine of Patent Document 1, in sowing grass seeds, cuts the ground of the sowing paper with a rotating disk-shaped blade, then expands the cutout by the disk for expanding the sowing groove expansion part, and then expands the seeding Since seeds such as grass seeds are sown inside the groove, there is no problem if the seeding groove maintains its original expanded state. There is a problem in that the seeding groove is blocked due to the collapse of the seeding groove, and the seed to be sown is sown in the ground rather than inserted into the soil of the sowing groove, resulting in a decrease in the seed germination rate.

Patent Document 2 relates to a garlic sowing machine, and unlike Patent Document 1, it is to sow the seeds after arranging the ground of the sowing ground evenly.

On the other hand, in Patent Document 3, the surface of the soil is cut by a disk coulter to divide the soil surface into two sides, and then the tip of the widened part installed close to the rear of the disk coulter penetrates into the divided groove to increase the width of the groove. It is widened, and the seed emitted from the slit inside the seed guide member is positioned inside the widened groove, but the widened part has a considerably wider thickness than the thickness of the disc coulter, so that the widened part is the disc nose There is a risk of clogging the groove by pressing the incised groove rather than entering the narrowly divided groove by the ulter.

Therefore, it is urgently required to develop a grass seed sowing machine that enables expansion without damage to the seeding groove cut for sowing seeds and allows the grass seeds to be accurately inserted into the soil of the sowing groove.

As shown in the drawing, the rotating plate 150 for seeding groove expansion and seed input is suspended from the second fixed shaft 152 toward the soil surface of the turf ground 1, and at one end, from the second fixed shaft 152. Support plate bodies 153 having a hexagonal coupling hole 153-1 coupled so as not to be moved and provided with a shaft hole 153-2 for rotationally coupling a plurality of rotating plate bodies 154 for expansion at the other end thereof; A tapered part 155 installed in a shape that gradually becomes narrower toward the outside around the shaft holes 153-2 of the support plate bodies 153, and a plurality of the rotating plate bodies 154 for expansion In a state in which the support plate bodies 153 and the tapered part 155 are respectively sandwiched together, a support ring 159 is provided on the shaft hole 153-2 and the rotation plate bodies 154 for expansion that coincide at this time. It includes fastening bolts 156 that pivotally support the rotation through the rotation hole 157-1 of the plurality of bearings 157 coupled therebetween.

The reason why the plurality of rotating plate bodies 154 for expansion are installed in a state where the support plate bodies 153 and the tapered part 155 are respectively sandwiched is between each of the rotating plate bodies 154 for expansion. This is to provide a grass seed input passage 158 for inputting grass seeds into an incision groove formed in the ground. Preferably (see FIGS. 5 and 7).

The upper side of the opening of the grass seed input passage 158 provided by the rotation plate bodies 154 for expanding the seeding groove and the rotation plate part 150 for seed input, respectively, is shown in FIGS. 1 and 2, respectively. The lower end of the grass seed supply pipe (not shown) extending from the grass seed hopper 30 toward the rotary plate part 150 for expanding the incision groove is positioned so as not to interfere with the rotation of the rotary plate bodies 154 for expansion. The grass seeds to be sown are supplied in the arrow directions of FIGS.

Each bolt shaft portion 156 - 1 of the fastening bolts 156 is bent at an angle corresponding to the inclination angle of the tapered portion 155 , and the rotating plate bodies 154 for expansion are formed in the support plate body. It was made possible to fasten each of the tapered portions 155 of (153) in a state of firmly clamping them.

An example of operation of the grass seed seeding groove forming mechanism 100 according to the present invention having such a configuration will be described with reference to the drawings and FIG. 8 again.

When the seeding machine 10 is driven, first, the hydraulic driving mechanism 15 of the seeding machine 10 is operated to operate in a descending state, and the bottom surface of the grass seed seeding groove forming mechanism 100, that is, the rotary disk-shaped blade part 130. , so that the rotating plate 150 and the rolling parts 170a and 170b for expanding the seeding groove and inserting the seeds are brought into contact with the soil surface side of the grassy ground.

The rolling parts 170a and 170b are configured to have a smaller diameter compared to the rotating disc-shaped blade unit 130 and the rotating plate unit 150 for expanding the seeding groove and inserting seeds so that there is a difference in height (h) by being installed. (See FIG. 1), the cut-out groove 2 (refer to FIG. 8) by the rotating disk-shaped blade unit 130 is formed to a depth corresponding to the height (h) difference. The rolling parts 170a and 170b act as a stopper for limiting the depth of the incision groove by the rotating disk-shaped blade unit 130 and the rotating plate unit 150 for expanding the seeding groove and inserting the seeds.

When the driving unit 16 of the planter 10 drives the planter 10 to proceed in the arrow direction (refer to FIG. 1), the lawn seed sowing groove forming mechanism 100 that is in contact with the soil on the grass ground ) of the rolling parts 170a and 170b, the surface soil layer of the grass ground is flattened by the rolling part 170a in the front, and then the rotating disc shape of the rotating disc-shaped blade part 130 is rotated. As the blade edge of the blades 134 enters a predetermined depth (h) toward the surface of the grassy ground soil, incision grooves for inserting the grass seed are formed in the thickness of the rotating disk-shaped blades 134 . Proceed in the same direction as the planter, forming the corresponding width.

Then, as each of the cut-out grooves cut by the rotary disk-shaped blades 134 , the rotary plate bodies for expansion of the rotary plate unit 150 for expanding the cut-out groove installed in correspondence with the rotary disk-type blades 134 . As the 154 is immediately inserted, as shown in FIG. 8 , an expansion groove 2 having a width corresponding to the spacing d of the plurality of rotation plate bodies 154 for expansion is formed.

The portion first entered into the cut-out groove formed on the grass ground by the rotating disk-shaped blades 134 of the rotating plate bodies 154 for expansion is a plurality of rotating plate bodies for expansion as shown in FIGS. 5 and 7 . It is a point P (see FIG. 5) at which they are narrowed to be almost adjacent. The reason is to facilitate the entry of the rotating plate bodies 154 for expansion into the incision groove cut by the rotating disc-shaped blades 134 .

In addition, the reason for the expansion of the rotating plate bodies 154 is narrowed so that a plurality of the rotating plate bodies 154 for expansion are rotated by the curved bolt shaft portion 156-1 of the fastening bolts 156. This is because the shaft hole 153-2 of the support plate body 153 to be fastened forms a tapered portion 155 forming an inclined surface that gradually narrows downward of the grass surface as seen in the drawing.

That is, since the rotation plate bodies 154 for expansion are rotatably coupled with the bolt shaft part 156-1 coupled to the shaft hole 153-2 of the tapered part 155 as a support point, the rotation plate for expansion The side of the sieves 154 toward the grassy ground is narrowed at an interval corresponding to the tapered portion 155 , while the upper portion opposite to the tapered portion 155 corresponds to the thickness of the support plate 153 . It remains in a state of being widened.

Therefore, in the process of passing the tapered portion 155 positioned to face the grass ground while the rotating plate bodies 154 for expansion are rotated, the entry into the incision groove is easily made at a narrow interval (d) as shown in FIG. 7 . On the other hand, the incision groove is expanded to a corresponding width (refer to FIG. 8), and from a point out of the tapered part 155, it is widened to a width corresponding to the thickness of the support plate body 153 (refer to FIG. 8). The process is repeatedly executed while the rotating plate bodies 154 for expansion rotate.

Between the rotating plate bodies 154 for expansion by the rotating plate bodies 154 for expansion that are rotatably coupled from both sides with the support plate 153 and the tapered part 155 interposed therebetween in the operation process as described above Grass seed input passages 158 that are in direct contact with the expanded cut-out groove 2 are provided at corresponding positions of the normal grass seed supply pipes, respectively, so that the grass seed input passages 158 are supplied with the grass seeds. It gives the benefit of increasing seed germination efficiency by allowing it to be safely inserted into the expanded incision groove (2) to be stably settled.

That is, the expanded incision groove 2 formed by the rotating plate bodies 154 for expansion of the present invention is not collapsed by the expansion rotating plate bodies 154 until the grass seed is put in. The arrow from the grass seed supply hopper 30 of FIG. In the case of the prior art (see Patent Documents), the grass seeds supplied in the direction are not accurately inserted into the expansion groove due to the deformation of the expansion groove by inserting the grass seeds after being expanded by the expansion plate, but fall outside the expansion groove. It gives the benefit of never letting grass seeds settle down due to growing grass seeds.

The expanded groove 2 into which the grass seeds are put is a compaction operation by a rolling operation by a pressure roller of the weight of the rolling part 170b at the rear, and the expansion groove 2 that has been in the cut state is covered while the expansion groove 2 is covered. ), the sowing operation of grass seeds is completed as the covering operation is completed to make it invisible.

The operation of the grass seed planter described above and the stop of the sea of clouds are performed by turning the power on/off.

In the above, the present invention has been described in detail only with respect to the described embodiments, but it is obvious to those skilled in the art that various changes and modifications are possible within the scope of the technical spirit of the present invention, and it is natural that such variations and modifications belong to the appended claims.

The present invention provides the utility of maximizing the germination efficiency of grass seeds by accurately inserting the grass seeds sown on the grass ground of various grass fields including golf courses into the incision groove without falling outside the grass ground.
