Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a weed removing device, and more specifically, it is a walking-type manually operated weed removing device that digs and removes weeds that grow between lawns, and also allows them to be collected without scattering. It relates to the device.

[0002]

[Prior art]

 In general, when weeds are removed, it is often the case that the fork-like nail of a rooting device is inserted into the soil and the root soil is dug up and pulled out. With such a weed remover, while considering the size of the weeds and the condition of the roots, the fork nails should be inserted shallowly into the soil to prevent damage to surrounding plants and trees that should be left as much as possible, and to be integrated with the nails. The weeds are dug up from the root while operating the grip. For example, a rooting device used in gardens of ordinary households has a fork-shaped claw body extending toward the front at the tip of a short grip handle. Then, the worker crouches near the weeds, inserts the nails toward the root, and manipulates them by prying them down like a handle. Also, in the case of a rooting device where the posture of the nail body is set almost at right angles to the handle like a rake, insert the nail body from the other side of the weed toward you and pull up the handle. It is operated like to plow soil. On the other hand, the above-mentioned rooting device may be used in a wide range of plants such as parks and medians of roads. However, due to the large amount of labor, time and inefficiency, mowers are often used which drive a portable engine to rotate the saw tooth disk horizontally.

[0003]

[Problems to be solved by the device]

 The rotary reaper described above can be operated by the worker while walking, and is extremely effective in a place where weeds are dense. However, it is almost impossible to selectively remove weeds in a place like a flowerbed where flowers are planted. On the other hand, the rake-type weed catcher has a drawback that it is necessary to squat down each time due to its short handle, which requires heavy labor. Moreover, depending on the size of the weeds and the degree of rooting, it is necessary to perform detailed operations while deciding whether to insert the nails deeply or shallowly into the soil. In particular, when the weeding range is wide, a large number of workers and long working hours are required, and the work efficiency is extremely low. In addition, the push-up device, which has a fork-shaped claw that extends forward, is mainly pushed by a large force during work. In addition, there is no fulcrum when pushing down the handle or when raising the handle in the rake style, and it is ergonomically difficult to operate, such as how to apply force, and smooth movement is likely to be impaired. . For example, in lawns and gardens, weed roots are often entwined with the grass roots. In such cases, it is extremely difficult to raise the roots of weeds without damaging the lawn. In particular, when there are weeds clinging to the ground such as clover, it cannot be removed without digging up several places of soil, and the lawn may be stripped. Also, when collecting dug up weeds on the spot, it is necessary to carry out an operation of packing them in bags. On the other hand, when leaving the weeds dug up on the spot, the scattered weeds must be collected afterward, and the time and effort cannot be ignored.

The present invention has been made in view of the above problems, and an object of the present invention is to make it easier to identify the presence of weeds and the location of excavation by raising the eye position and avoiding crouching one by one. To reduce the burden of weeding work by operating while moving in a walking posture, to give the force applied to the weeding machine during the work by natural movements associated with the movement of the worker, and moreover, it is mainly a pulling movement with high operability. In order to ensure smooth and smooth operation, and to provide a fulcrum that can use the principle of "lever" without introducing a special member to the main body of the weeding machine, the raising operation is extremely simple and easy. It is an object of the present invention to provide a weed removing device that realizes that the weeds can be picked up and that weeds can be collected by a simple operation following the dug up operation.

[0005]

[Means for Solving the Problems] The present invention is applied to a weeding machine capable of removing a weed by inserting a nail body and digging up a grass root. With respect to the feature, referring to FIG. 1, a pair of left and right wheels 3 is supported at the central portion of the weeding machine body 1 in the front-rear direction. On the front surface of the main body 1 of the weeding machine, a reiki 6 provided with a nail body 6a is provided, while on the rear surface thereof, a scraper 7 having a nail body 7a for scraping the weeds excavated by the reiki 6 is provided. It A long handlebar 5 is attached to the above-mentioned weeding machine main body 1 so as to move the weeding machine by a pulling motion in a walking posture and to tilt it back and forth while inclining forward. . The lower end 6b of the claw body 6a of the reiki 6 and the lower end 7b of the claw body 7a of the scraper 7 allow the weeding machine main body 1 to be tilted forward and backward with the ground contact point M of the wheels 3 and 3 as a fulcrum. It is set at a position higher than the grounding point of wheels 3 and 3.

As shown in FIG. 2, the reiki 6 can be mounted on the front surface of the main body 1 of the weeding machine so that the vertical position can be changed. The scraper 7 can also be mounted on the rear surface of the weeding machine main body 1 so that the vertical position can be changed (see FIG. 3). The left and right width of the scraper 7 is preferably formed wider than the left and right width of the reiki 6, as shown in FIG. Further, the reiki 6 is bent forward as it goes downward, and the lower end 6b of the claw 6a is inclined with respect to the ground 15 (see FIG. 1). In addition, a plurality of reikis 6, 6A, 6B may be arranged side by side on the front surface of the weeding machine main body 1 (see FIG. 5).

[0007]

[Action]

 A reiki 6 is provided on the front surface of the weeding machine main body 1, and a scraper 7 is also provided on the rear surface. At this time, at least one of the lower end 6b of the claw 6a of the reiki 6 and the lower end 7b of the claw 7a of the scraper 7 is set higher than the ground contact point M of the wheels 3,3. That is, the handlebar 5 tilted forward is grasped, the weeding machine main body 1 is towed in a walking posture, and the ground contact point M of the wheels 3 and 3 can be tilted back and forth. Keep it. The weeder to be weeded and the position and the number of times to insert the nail body 6a of the reiki 6 are determined from a high position in the walking posture, and the weeding machine body 1 is arranged near the weeds. The weeding machine main body 1 is extremely easily moved by rolling a pair of wheels 3 supported on a central portion. Reiki 6 is directed toward the root of the weed, and handlebar 5 is tilted forward and downward to insert claw 6a of Reiki 6 into the soil. If the handlebar 5 is slightly pulled and tilted upward, the soil at the base of the weeds is dug up, and the root is easily dug out of the soil. As it is, when the handlebar 5 is tilted a little further forward and upward, the grounded scraper 7 scrapes the dug up weeds and collects them without scattering them on the spot. Move to the next position by scratching out the weeds and dig up other weeds in the same way. When a lot of weeds are entangled with the scraper 7, remove it and collect it.

If the reiki 6 and the scraper 7 can be mounted on the weeding machine main body 1 so that the vertical position can be changed, when the weeding machine main body 1 is towed, the wheels 3, 3 The degree of tilting back and forth with the ground contact point M as the fulcrum can be changed as desired. That is, the amount of insertion of the reiki 6 can be adjusted in consideration of the degree of weed roots, and the lower end 6b of the claw body 6a of the reiki 6 and the lower end 7b of the claw body 7a of the scraper 7 are attached to the wheels 3,3. If you feel that the ground contact point M is unfavorable for weeding, you can replace the reiki 6 and scraper 7 with different positions above and below the weeding machine main body 1. When the left and right width of the scraper 7 is larger than the left and right width of the reiki 6, the scraped surface of the dug weed becomes wider, and the scraping is easier and the scattering on the spot can be reduced. If the reiki 6 is bent forward as it goes downward, and the lower end 6b of the claw 6a is inclined with respect to the ground surface 15, the reiki can be adjusted to an appropriate depth with respect to the roots of weeds stuck to the ground. It can be plugged in, and even if the weeding machine main body 1 is pulled as it is, the lawn around it is not damaged, and unnecessary deep digging is avoided. If multiple Reikis 6, 6A, 6B can be installed side by side on the front of the weeding machine body 1, the number of Reikis can be increased according to the growth and spread of weeds. it can. In this way, weeds widely clinging to the ground can be dug up with less effort.

[0009]

[Effect of device]

 According to the weed removing device of the present invention, the main body of the weeding machine can be moved by grasping the handlebar while keeping the walking posture. Then, it becomes easy to identify the excavated part of the weed from a high position and to search for another weed. The digging work does not have to be carried out one by one, and can be performed in relation to the operation of pulling the weeding machine main body 1. Also, it can be operated with a small amount of force using the wheel ground contact point as a fulcrum, reducing the work load. In addition, the weeds dug up are not scattered and are scraped up by the operation that is continuous with the dug up, and the operability can be remarkably improved and the work efficiency can be dramatically improved. If you can change the mounting position of the reiki, you can improve the operability according to yourself. If the scraper mounting position is also changeable, it will be easy to make adjustments to increase the continuity of excavation due to reiki and scraping operation by the scraper. If the scraper is wider than Reiki, the excavated weeds can be efficiently scraped and the subsequent picking work can be reduced. By adopting a reiki that bends forward, it is possible to avoid excessive excavation and to damage or dig up the surrounding flowers and lawn as much as possible. By adding reiki and lining up a lot, weeds can be dug up in a wide area with a small amount of labor and root weeds or dense weeds.

Embodiments The weed removing device of the present invention will be described in detail below with reference to the drawings showing the embodiments. FIG. 1 is a side view of a weed removing device in which axles supporting wheels to the left and right are provided in the weeding machine main body. The weeding machine main body 1 is formed into a U-shape by bending one thin steel plate upward at the front and rear portions. Further, it is provided with a horizontal main body plate 1A in the central portion, a front apron 1B standing upright vertically at the front, and a rear apron 1C bent vertically upward at the rear. Further, the weeding machine main body 1 has side plates 1D and 1D formed by bending the left and right side surfaces of the main body plate 1A upward, and as shown in FIG. 2, an axle shaft extending leftward and rightward through them. 2 can be supported. Wheels 3 and 3 having a bearing 3a are mounted on the left and right sides of the axle 2. On the other hand, on the upper surface of the main body plate 1A, a connector 4 (see FIG. 1) that extends obliquely forward is attached, and a long handlebar 5 that can be operated while walking is detachably attached. The reiki 6 can be mounted on the front apron 1B by changing the mounting position up and down. The scraper 7 is also mounted on the rear apron 1C so that the mounting position can be changed up and down.

More specifically, the connector 4 is composed of a tubular portion 4a into which the tip of the handlebar 5 is inserted and fixed, and a substrate portion 4b integrated with the tubular portion 4a by welding or the like. As shown in FIG. 4, the base plate portion 4b is fixed to the upper surface of the main body plate 1A via a plurality (four in the drawing) of hexagon socket head cap screws 8,8. A through hole 9 is provided in the tubular portion 4a, and a pin 10 (see FIG. 1) is inserted through the tip of the handlebar 5 to fix the handlebar 5 in a posture inclined forward by 45 degrees, for example. It is getting started. The handlebar 5 is towed for moving the weeding machine main body 1 and tilted for weeding up and weeding. Although it is not shown in the drawing in its entirety, it can be a straight rod or a bent shape so that the grip is horizontal. Although it may be a single bar, it may be telescopically expandable and contractable so that the length can be changed according to the height and body shape of the operator. By the way, as shown in the figure, when the axle 2 is on the upper surface of the body plate 1A and interferes with the tubular portion 4a, the upper surface of the tubular portion 4a is cut out so that the axle 2 can pass through. You need to be careful. Of course, the mounting position of the connector 4 may be changed, or the individual wheels 3 may be individually supported by the respective side plates 1D.

As shown in FIG. 2, the above-mentioned reiki 6 may be, for example, one having about three claws 6a. This reiki 6 is fixed to a stop hole 1b formed at the upper center of the front apron 1B with a bolt 11 and a wing nut 12, and is removable. The reiki 6 itself is provided with a long hole 6c extending in the vertical direction, so that the reiki 6 can be mounted at an arbitrary height position with respect to the front apron 1B. As shown in FIG. 3, the scraper 7 is mounted on the rear apron 1C, but the same mounting configuration as that of the rake 6 is adopted, and the scraper 7 is fixed with the bolt 13 and the wing nut 14 using the stop hole 1c and the long hole 7c. can do. As shown in FIG. 1, both the lower end 7a of the claw 7a and the lower end 6b of the claw 6a of the scraper 7 and the reiki 6 are set and fixed so as to be higher than the ground contact point M of the wheels 3 and 3. It As a result, when the weeding machine body 1 is in a horizontal posture, the lower ends of the weeding machine body 1 are separated from the ground 15, and there is room for tilting the weeding machine body 1 in the front-rear direction. By the way, the reiki 6 may have a plate shape extending vertically, but as shown in the figure, it is formed downward by being bent forward in an arc shape as it goes downward, or by being bent in a V shape. It is preferable that the triangular claw body 6 a be inclined with respect to the ground 15. By doing so, as will be described later, the weeds are not deeply inserted into the roots of the weeds, and it is possible to avoid digging up to the roots of the surrounding flowers that should be left behind.

The scraper 7 described above is wider than the Reiki 6, and the claws 7a thereof are formed in a larger number than that of the Reiki 6 (see FIG. 2). This is to make it convenient to scrape the weeds dug up, but the claw body 7a does not need to be as sharp as the Reiki 6 and is scraping the weeds scattered on the ground. It only has to be able to hold until a certain amount is accumulated. Therefore, the claws 7a may be shorter, smaller in pitch, or larger than the claws 6a of the Reiki 6, and the scraper 7 itself may be a flat plate-like member as shown in the figure. Of course, in some cases, the reiki 6 may have a curved front surface, and the claw 7a may be provided with a substantial rake angle, and the shape thereof can be appropriately selected. By the way, the mounting position of the connector 4 and the installation angle of the handlebar 5 described above often affect the digging operation of the weeding machine main body 1 by the reiki 6 and the scraping operation by the scraper 7, and also work. The operation feeling may differ depending on the person. Therefore, although not shown in the figure, the installation position of the connector 4 can be changed or the fixing angle of the handlebar 5 can be changed in the same manner as the mounting procedure of the Reiki 6 or the like. In addition, it is good to be able to adjust the rotation of the connector 4. In the operability test conducted by the present inventors, if the handlebar 5 is moved to move the weeding machine main body 1, the reiki 6 excavates and the scraper 7 scrapes. It was confirmed that the operation can be performed continuously, which is extremely convenient. Further, the handlebar 5 and the reiki 6 have a positional relationship like a hoe handle and a blade, but the lower the position of the connector 4 for fixing the lower end portion of the handlebar 5 is, the higher the operability is. Was also found.

The weed removing device configured as described above can be efficiently removed by operating as follows. In FIG. 1, the bolt 11 is inserted into the stop hole 1b provided in the front apron 1B of the weeding machine body 1 and the long hole 6c of the reiki 6, and the wing nut 12 is used while adjusting the vertical mounting position of the reiki 6. Fix it. Then, the lower end 6b of the claw 6a of the reiki 6 is set to be higher than the ground contact point M of the wheels 3, 3 by, for example, about 1 cm, and there is room for moving the claw 6a up and down with respect to the ground 15. deep. Next, the scraper 7 is attached to the rear apron 1C of the weeding machine body 1 while adjusting the upper and lower attachment positions of the scraper 7 using the bolt 13 and the wing nut 14. Also in this case, the lower end 7b of the claw 7a is adjusted to float about 1 cm from the ground 15, and the handlebar 5 is tilted to move the weeding machine main body 1 back and forth with the ground contact point M of the wheels 3 and 3 as a fulcrum. Be prepared to tilt. Finally, insert the lower end of the handlebar 5 into the connector 4 on the upper surface of the main body plate 1A, and secure it with the pin 10 so that it will not come off. Hold the handlebar 5 in the walking posture, try the digging up action of the reiki 6 and the scraping action by the scraper 7, and if the operation feeling does not suit you, adjust the vertical position of the reiki 6 and scraper 7 again.

When the preparation is completed, weeds are found standing on the lawn, and the claw body 6a of the Reiki 6 is carried to a place necessary for excavating the weed. The handlebar 5 can be easily moved to the position of the weeds by rolling the wheels 3 by pulling or pushing. When the weeding machine main body 1 is stopped and the handlebar 5 is slightly tilted downward, the ground 15 in FIG. 1 becomes as shown by the chain double-dashed line, and the weeding machine main body 1 makes the ground contact point M of the wheels 3 and 3. With the fulcrum as a fulcrum, the nail body 6a of the reiki 6 is inserted into the base of the weed. The reiki 6 is bent forward in an arc shape, and the lower end 6b of the claw 6a is inclined with respect to the ground 15 and does not go deep into the soil. With the reiki 6 inserted, pull the handlebar 5 a little to the front, and the claw 6a moves forward like scooping the roots of weeds. The claw body 6a is shaped like a triangular toothed fork, and when the handlebar 5 is tilted upward a little, the weeds are dug up by loosening the soil around the roots. Of course, some soil is dug up, but it does not extend to the surrounding lawns. If the handlebar 5 is tilted further upward and the claws 7a of the scraper 7 are brought into contact with the ground as shown by the alternate long and short dash line in FIG. 1, the scraped weeds 7 will be wide. Scraped by. If the roots of weeds are spread over a wide area, the rake action of roots by Reiki 6 is repeated several times to dig up the weeds. In the case of weeds clinging to the ground 15 for a long time, the handlebar 5 may be pulled while the reiki 6 is inserted. Pull the handlebar 5 and drag the weeds excavated by the scraper 7 to move the weeder body 1 to the position of the next weed and perform the same operation. At that time, the weeds scraped up before are entangled in the scraper 7, and rarely remain scattered. When many weeds adhere to the scraper 7 by repeating the operation, remove them.

Such an operation is achieved only by an operation of pulling and tilting the handle bar 5, and even if the operation is continuous, the weeds can be removed smoothly. In addition, the force required for excavation is reduced by the principle of "lever" using the ground contact point M of the wheel 3 as a fulcrum, and the force can be applied comfortably. The worker is constantly walking and does not have to crouch down for excavation or scraping, which significantly reduces the work load. By the way, in the reiki 6 and the scraper 7 described above, the lower ends of the claw bodies 6a, 7a are set at a position higher than the ground contact point M of the wheel 3. However, it suffices if the weeding machine main body 1 can be tilted back and forth around the ground contact point M of the wheel 3 as a fulcrum. Therefore, at least one of the lower ends of the claw bodies is set to a position higher than the ground contact point M. You can leave it. For example, when the weeding machine main body 1 is in a horizontal posture, the claws 7a of the scraper 7 come into contact with the ground, but the claws 6a of the reiki 6 are raised, or the opposite form may be used. Yes, it can be selected according to the preference of the operator who operates it. In addition, when weeds are widely overgrown, as shown in FIG. 5, reikis 6A and 6B may be added to the left and right, for example, three reikis may be mounted side by side. Reiki 6 itself is gradually worn away by soil, and if some are prepared, it can be used in such a form.

FIG. 6 shows an example in which the side plate 1D is bent downward and the axle 2 is supported at that portion. In this case, the axle 2 does not interfere with the connector 4 and the handle bar 5 can be easily attached to the connector 4. Further, it becomes easy to secure a space when a mechanism for changing the set angle of the handlebar 5 is adopted, and the operability of setting the angle is also improved. FIG. 7 is an example in which the top and bottom of the weeding machine main body 1 in FIG. 1 are reversed. In this example as well, the mounting positions of the reiki 6 and scraper 7 can be changed, but the claws should be formed directly on the lower end of the front apron 1B, and the claws should also be formed on the rear apron 1C. You can also At this time, if it is desired to change the distance between the lower end of each claw and the grounding point of the wheel 3, the side plate 1D has a structure in which the bearing position of the wheel 3 can be changed, although not shown. You should give consideration such as. As described above, the method of fixing the reiki, scraper and axle after fixing the position to the weeding machine main body is not limited to the form using the bolt and the wing nut, and other known means may be used. For the simplest weeding machine of this type, the position adjustment part should be eliminated. That is, if each claw body is formed on the main body of the weeding machine, and the axle is also fixed, the reiki and scraper cannot be replaced, but this is sufficient for household use, and the cost can be reduced.
