Description

Lawn weed removal and aeration device

The present invention relates to a device for aeration of a lawn at the same time to remove the weeds that occur partially in the lawn, such as gardens, parks, football fields, golf courses.

Crops are usually grown collectively in a place far from authorization. Therefore, most of the weeding operations in crop cultivation are performed on the entire agricultural land using chemical methods using herbicides, mechanical methods using herbicides, or mulching (covering farmland with polyethylene film).

On the other hand, it is not a crop, but gardens, parks, football fields, golf courses, lawns, etc., many weeds are generated and need continuous management. For example, because the United States recognizes lawns in the front yards of homes as local commons, there is an organization called Home Owner's Association, which regularly patrols and monitors the beautification of the environment. Warns you that your neighborhood is of low value and is fined if you don't correct it right away.

The use of herbicides to remove grass weeds can damage other plants (grass, flowers or trees) nearby, as well as damage people, pets and livestock. Therefore, the use of herbicides to remove lawn weeds is possible only in very exceptional circumstances, such as by sealing the affected areas with vinyl.

Therefore, a method for removing grass weeds by a mechanical method has been proposed.

Republic of Korea Patent Application Publication No. 10-2009-0109173 (automatic weed removal device and its method) is a traveling means, a removal device main body provided in a removable state on the traveling means, and the presence of obstacles in the traveling direction mounted on the front of the traveling means; , A plurality of first photographing means for detecting the bending and inclination of the ground, and a plurality of second photographing means mounted on the front surface of the main body of the removal device to detect the presence, location, frequency, size, etc. of the weeds to be removed; Means, drawing means for removing the corresponding weeds to be removed, which are built into the main body of the removal device and driven to the left, right and up and down, and for removing the weeds, including information about the weeds to be removed; A storage means for recording various data such as an operation distance and a speed of the drawing means, and input data from the first and second photographing means to the storage means. There is provided an automatic weed removal device comprising control means for performing control over the apparatus to remove weeds while properly operating the traveling means and drawing means after comparison and calculation with the recorded data (see FIG. 8).

According to this, there are various types of grass and various types of weeds, colony size, and growth. However, it is not technically easy to detect the presence, location, frequency, and size of the weeds to be removed by photographing the grass while driving in real time. . Furthermore, the weed removal device has a problem of low practicality because accessory devices (first, second photographing means, control means for interpreting and recognizing image information, drawing means, etc.) are very expensive and complicated.

Republic of Korea Patent No. 10-1219495 (golf ball collecting, weeding remote control robot) is a piston for performing a vertical reciprocating function, a cylindrical body portion installed on the lower end of the piston portion, while rotating around the body portion A robot having a weeding unit including a plurality of weeding blades which are mounted at a predetermined interval in the body part to perform the weeding operation is proposed (see FIG. 9). In this case, when the weeding operation is required, the piston unit is lowered and the body unit on which the weeding blade is mounted is located at a short distance from the ground, so that weeding is performed.

However, this prior art does not "remove grass weeds" but merely functions to mow grass and weeds (only remove part of the ground) as needed.

Therefore, at present, since there is practically no mechanism for removing weeds on the lawn, it is a reality that a person removes weeds manually by using a device such as a homina or a rake.

Grass is not a single grass with a single root like a general grass, but a hard crawling stem grows long in the basement, and the roots fall from the crawling stem and the stems and leaves grow (see FIG. 10). Therefore, on the surface of the lawn, many crawling stems and roots are entangled with freezing and grow into a very firm mat, and the roots extend 30 ~ 60cm underground from these mats, so the mat is very firmly grounded. Attached.

When weed seeds fly into these lawns, weed roots are present between the entangled grass stems and roots, and when appropriate conditions grow and "tangle" roots with the grass stems and roots. Because weeds are entangled in the grass in this way, it is relatively easy to mow by hand (removing some of the weed's ground), but weeding (removing weed roots) requires tools such as hoe, rake and knife. Using it can be very difficult and cumbersome.

On the other hand, in order to further increase the grass to grow more rich grass seed is sometimes sprinkled, but also to mechanically cut the crawling stem to increase the number of growing grass (see Fig. 11). In addition, in order to reduce the damage caused by the pressure and replace the part of the soil where the grass grows, and to increase the air permeability of the lawn, a coring or aeration operation that digging a part of the lawn (about 3 to 9%) in a small size (Fig. 12).

However, conventional lawn weeding and such cutting, coring or aeration were not related.

The present invention is to provide a lawn weed removal device to easily remove the weeds partially generated in the lawn, such as gardens, parks, football fields, golf courses, etc., with manual work or fully automatically.

In addition, the present invention is to provide a grass weed removal device that can give aeration effect while removing the grass weeds.

The present invention for achieving the above object is a ① drawn portion having a plurality of hooks of the harpoon shape is formed at one end or two or more barbs are arranged vertically in the lower portion of the support; ② up and down driving unit for reciprocating the draw up and down; ③ the frame and the transfer unit having two or more moving wheels to accommodate the drawing and the up and down driving portion; includes a grass lap diameter and a portion of the root is cut by the hook of the drawing when the up and down driving unit is operated while passing on the lawn A lawn weed removal and aeration apparatus, characterized in that the roots of the weeds are drawn together with the grass creeping diameter and a part of the roots.

As described above, according to the present invention, the grass crawling diameter and a part of the root and the weed root are pulled out by the vertical reciprocating motion of the hook, so that weeds can be easily removed manually or automatically in a later step.

In addition, according to the present invention, since the grass creep diameter and the root are partially cut by the hook, and a hole is formed in the ground, an aeration effect can also be obtained.

In addition, according to the present invention, since the partially cut grass lap diameter and roots are partially removed together, the growth of the grass, which has become stagnant and stagnant, can be improved.

In addition, according to the present invention, in the process of strongly inhaling the weeds pulled out from the outside because the seeds of the weeds hidden between the grass stems and roots are also removed, so the effect of 'pre-weeding' can be obtained.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. However, the accompanying drawings are only examples for easily describing the content and scope of the technical idea of the present invention, and thus the technical scope of the present invention is not limited or changed. It will be apparent to those skilled in the art that various modifications and variations are possible within the scope of the present invention based on these examples. In addition, where reference numerals are given to components of the claims, it will be apparent that the above descriptions are merely illustrative and are not intended to limit the components.

First Embodiment As described above, the present invention relates to a lawn weed removal and aeration apparatus including a drawing unit 10, a vertical driving unit 20, and a conveying unit 30.

In the first invention, the drawing portion 10 is a hook 12 is coupled to the support plate 11a of a predetermined plate or rod shape. 1 shows an example of a drawing part 10 according to the present invention. In the present invention, 'pulling (拔出)' means 'pull out' means that the part of the grass and the root of the weeds by the hook 12 is pulled up and pulled out.

The hook 12 is the most essential function of the device according to the present invention, and as shown in the figure, one or more barbs 12a (at the end of fishing or harpoon, at the end of fishing or harpoon, when a fish bites or stings). The hooks made like thorns are shaped like harpoons so that they do not fall out. An example of a hook 12 is shown in FIG. 2. Weed roots will be about 10 cm or less because weed grass and roots are roughly 10-20 cm deep, and weeds do not grow long when we periodically weed with the device according to the present invention. When the main root and main stem of the is removed will be weeded. Therefore, the length (L) of the hook 12 is 10 ~ 15cm, the vertical length (ℓ) of the barb 12a is 3 ~ 5cm, the diameter (w) of the circle formed by the upper edge of the plurality of barbs 12a is 2 ~ 3cm should be enough. It is possible to have only one barb 12a in one hook, but it is preferable that three to four pieces are formed in consideration of drawing effect and manufacturing cost. 1 illustrates a hook 12 with three barbs 12a in FIG. 2.

In the present invention, the up and down drive unit 20 is an element that functions to reciprocate the drawing unit 10 up and down. For example, the up and down drive unit 20 may be composed of one or a plurality of hydraulic cylinders and a hydraulic pump for driving the cylinder body is coupled to the frame 31, the cylinder rod is connected to the drawing unit (10). Alternatively, one end may be a lifting shaft coupled to the frame 31 and the other end to the drawing unit 10, and an electric motor or an engine driving the same. Exercise equipment for reciprocating an object up and down is well known in the art and may be appropriately selected and applied. Hereinafter, a further description of the specific structure and operation of the up and down drive unit 20 will be omitted.

The transfer unit 30 is a frame 31 and the two or more moving wheels 32 to accommodate the drawing unit 10 and the up and down driving unit 20 to drive the drawing unit 10 and the up and down driving unit 20 ) At this time, as described above, the drawing unit 10 and the frame 31 are coupled via the upper and lower driving unit 20.

The transfer unit 30 may be a semi-automatic device such as a lawn mower that the operator walks on while holding a handle, or may be an independent vehicle having a driving unit (engine or the like) and a steering unit, or a predetermined towing unit (not shown). It may be a manual driving vehicle which is driven in combination with other driving vehicles such as a tractor or a cart. 3 shows an example of a lawn weed removal and aeration apparatus according to the present invention having a transfer part 30 similar to a lawn mower. 4 and 5 illustrate an example in which the transfer unit 30 is an independent vehicle, and when the transfer unit 30 is an independent vehicle, the frame 31 becomes a vehicle body.

The lawn weed removal and aeration apparatus according to the present invention including the drawing unit 10, the up-and-down driving unit 20 and the transfer unit 30 thus exhibits the weeding and aeration effect in the following manner. A vertical cross-sectional view (FIG. 6) looking at both barbs 12a for the hook 12 having two barbs 12a penetrating the surface and coming out of the surface, and a vertical view in the direction of one barb 12a. A cross section is shown (FIG. 7).

When the device according to the present invention passes over the lawn and the up-and-down driving unit 20 operates to lower the drawing unit 10, first, the hook 12 of the drawing unit 10 penetrates the ground surface of the lawn and is adjacent to the ground surface. Some of the turfgrass roots and roots in the sun are cut (pictured above in FIGS. 6 and 7). Subsequently, when the drawing unit 10 is lifted by the up-and-down driving unit 20, the hook 12 is raised above the ground surface. At this time, the roots of the weeds together with the grass crawling diameter and a part of the roots on the barbs 12a of the hook 12, and the ground surface The grass leaves, etc., which are laid on the surface are caught and pulled out of the surface together, that is, pulled out (the bottom figure in FIGS. 6 and 7). At this time, a suitable cutting is made in the grass, and a proper degree of aeration hole (coring) is formed in the grass.

In practice, the amount of grass and weeds to be drawn, the degree to which the grass is cut, the aeration hole, depending on the spacing between the hooks 12, the size of the hooks 12 and barbs 12a, the length of the hooks 12 digging into the ground, etc. The size and depth are adjusted. To this end, it is desirable to allow the reciprocating width of the up and down drive unit 20 to be adjusted, to replace the hook 12 or to change the arrangement of the hook 12.

In this process, grasses and weeds are randomly drawn or loosened due to a significant resolution of weed root entanglement. The grass and weeds drawn by the hook 12 or loosened in the roots are referred to as "draws". The worker can then easily pick up the draw, including the weeds drawn by hand or with a suitable tool, or with loosely entangled roots.

On the other hand, it may be cumbersome and difficult to manually remove (clean) some of the drawn or loosed weeds or grass, ie the draw. In the present invention, it is preferable to add a predetermined means for automation. That is, it is preferable to additionally attach the drawing material removing means 40 of a size corresponding to the range in which the hook 12 is arranged in the rear of the drawing part 10 in the traveling direction of the apparatus according to the present invention.

As an example of the drawing material removing means 40, a dust collecting means 40a having a suction port 41 and a drawing load tank 43 having a size corresponding to the range in which the hook 12 is arranged is possible. 4 shows an example in which the dust collecting means 40a is additionally mounted, and as shown in the figure, a loading tank 43 provided with a dust collecting fan 44 is provided at one side of the transfer part 30, and the drawing part 10 is provided. The suction port 41 installed at the rear side is in communication with the dust collecting fan 44 and the suction pipe 42 so that the grass and the weeds pulled up by the drawing unit 10 are drawn into the loading tank 43 by air. Is to be inhaled. At this time, if the inlet 41 is brought into close contact with the ground, most of the grass where the creep and the roots are entangled with each other by strong suction force remains intact and loosely drawn so that weeds and some of the roots that are still entangled with the grass and the dead leaves are sucked in. do. That is, it is also possible to forcibly pull out weeds not completely drawn out by the strong suction force of the dust collecting means 40a. In addition, it has a rotating brush that allows you to choose from a variety of methods (not shown) to scrape loose material.

(Second Invention) On the other hand, in the present invention, the drawing unit 10 may be a method of vertically reciprocating, but it is also in the form of a roller 11b, so that the roller 11b may be drawn while rolling a lawn.

That is, the second invention relates to a lawn weed removal and aeration apparatus including a drawing portion 10 and a conveying portion 30 in the form of a roller 11b. 4 shows an example of the second invention.

Accordingly, in the second invention, the drawing portion 10 has a structure in which a plurality of harpoon hooks 12 are arranged on the outer circumferential surface of the cylindrical roller 11b, and the drawing portion 10 is plated in the first invention. Or the hook 12 is coupled to the rod-shaped support 11a is different from the form.

In addition, in the second invention, since the drawing portion 10 rolls in the form of a roller 11b, the up and down driving portion 20 in the first invention is not required.

In the second aspect of the present invention, the transfer unit 30 includes a frame 31 and two or more moving wheels 32 that rotatably fix the rotating shaft of the roller 11b such that the roller 11b is spaced a predetermined distance from the ground. Have. That is, the transfer part 30 and the two or more moving wheels 32 are fixed to the frame 31 so as to be rotatable, respectively. At this time, it is preferable that the height of the rotating shaft of the roller 11b is adjusted (not shown) so that the depth at which the hook 12 enters the ground surface can be adjusted.

On the other hand, in the second invention, when the drawing unit 10 is moved while rotating passively, the drawing effect can be lowered. Therefore, it is preferable that this 2nd invention further has the rotation drive part (not shown) which rotates the rotating shaft of the roller 11b corresponding to rotation of the moving wheel 32 of the conveyance part 30. FIG.

The shape, structure, size, and function of the other hooks 12, such as whether the transfer unit 30 is a stand-alone vehicle or a manual vehicle, a method of showing weeding and aeration effects, whether or not the additional removal means 40 is installed, and the like. Since the description is the same as or substantially the same as the case of the first invention described above, a description thereof will be omitted.

According to the first invention and the second invention as described above ① part of the grass and weeds, part of the dead grass piled up are removed and removed ② the grass diameter and the stem is partly cut ③ ③ the surface surface is partially mixed and aeration Holes are formed (coring). Therefore, by the device of the present invention it is possible to obtain the effects of weed removal of the lawn, soil fluidization (hardened land becomes coarse), grass growth and shoot induction, air circulation and drainage.

On the other hand, the lawn weed removal and aeration apparatus according to the present invention because the surface of the lawn is somewhat uneven and the hole is formed in the surface, if necessary, it is possible to put a ground clearance roller at the rear end of the device, or a predetermined sand spray means Of course.
