Description

[Technical field]

[0001] The present invention relates to a scattering prevention cover and a brush cutter provided with the scattering prevention cover. [Background technology]

[0002] Conventionally, there has been known a scattering prevention cover for a grass cutter that protects a grass cutter from being hit by scattered grass and stones when weeding with a grass cutter (Patent Document 1). The scattering prevention cover is provided with a base plate that covers the upper surface side of the cutting blade, a cover body that is provided on the base plate and has a peripheral wall that covers the back side and the left and right side sides of the cutting blade and has an open bottom, and a cutout portion formed on the front side of the peripheral wall. A part of the cutting blade that rotates is exposed to the outside of the scattering prevention cover from the cutout portion. The scattering prevention cover is fixed to the clamper by a bolt and a nut through the tip of the operating rod so that they do not move relative to each other. This makes it possible to prevent the grass and other cutting objects from scattering, and to prevent hard objects such as pebbles from scattering, thereby improving safety.

[0003] Another grass cutter scattering prevention cover is a double disk-shaped cover made of a relatively hard plastic on the inside and synthetic rubber on the outside, with the outermost peripheral edge of the outer synthetic rubber disk bent upward to create a curved shape (Patent Document 2). By attaching a scattering protection cover to the tip of the grass cutter body, grass, stones, and other objects do not fly off during operation. Since it is made of synthetic rubber in a disk shape, by bending the outermost edge upward, it is possible to cut grass in difficult-to-cut places, as the synthetic rubber curves back, making it possible to cut grass in narrow gaps. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2022-119244 A [Patent Document 2] JP 2004-89169 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the shatterproof cover described in Patent Document 1, the cutting blade is exposed at the cutout, so there is a risk that stones will hit the exposed cutting blade and scatter, causing damage to people and objects in the vicinity. In addition, stones and the like may scatter around from the cutout formed in the shatterproof cover. Furthermore, because the operating rod of the grass cutter and the shatterproof cover are fixed so that they do not move relative to each other, a space is created between the shatterproof cover and the cutting blade, making it impossible to cut weeds in that space. In particular, when weeding weeds near a wall, the cutting blade at the cutout may hit the wall and be damaged, and it is difficult to cut weeds that exist between the shatterproof cover and the cutting blade.

[0006] In the grass cutter scattering prevention cover described in Patent Document 2, a disk-shaped protective material with an upwardly curved outermost edge is provided on the top of a rotating nylon cord cutter. However, the protective material only covers the top of the nylon cord cutter, leaving the sides exposed, so grass, branches, stones, etc. cut by the nylon cord cutter can scatter around and cause damage to people and objects. Furthermore, because the protective material is larger than the nylon cord cutter, it is difficult to cut grass near a vertical wall because the protective material becomes an obstacle.

[0007] Therefore, an object of the present invention is to provide a scattering prevention cover and a brush cutter equipped with a scattering prevention cover that can prevent stones, grass, etc. from scattering around and can efficiently cut weeds along walls. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention provides a scattering prevention cover that is detachably attached to a brush cutter having a grass cutting unit that cuts weeds by rotating, a rod unit with the grass cutting unit attached to its tip, and a drive source that is attached to the rod unit and rotates the grass cutting unit, the scattering prevention cover comprising: a protective cover that covers the top and sides of the grass cutting unit and has a through hole through which the rod unit can movably pass; a rod support unit that is attached to the protective cover and has an extensible end fixed to either the rod unit or the grass cutting unit; It is preferable that a flexible peripheral material is provided around the entire periphery of the side of the protective cover, and that the peripheral material is positioned so as to be in contact with the grass cutting part, with at least a portion of the peripheral material being in contact with the ground.

[0010] It is also preferable that the protective cover has a circular shape when viewed from above, and the rod support portion is provided on an upper portion of the protective cover and in the vicinity of the through hole.

[0011] It is also preferable that the protective cover further includes a cylindrical support portion through which the rod portion movably passes to support the rod portion.

[0012] It is also preferable that the protective cover further includes an auxiliary elastic portion having elasticity, one end of which is detachably fixed to the rod portion and the other end of which is fixed to the protective cover.

[0013] In another aspect of the present invention, there is provided a brush cutter having any one of the above-described splash prevention covers removably provided thereon. Effect of the Invention

[0014] According to this configuration, the rod portion is movable through the through hole and the rod support portion is elastic, so that the grass cutting portion can move within the protective cover. This eliminates the gap between the grass cutting portion and the protective cover, so that it is possible to remove the weeds located in the gap. In the conventional scattering prevention cover, the scattering prevention cover and the rod are fixed so as not to move, so that it is difficult to completely remove the weeds near the wall. In contrast, in the scattering prevention cover of the present invention, the grass cutting portion can move within the scattering prevention cover, so that it is possible to remove the weeds near the wall without leaving any behind, as shown in FIG. 6. In addition, since the protective cover covers the upper and side portions of the grass cutting portion, scattering of stones, branches, etc. to the surroundings can be suppressed.

[0015] According to this configuration, the peripheral material comes into contact with the grass cutting part as the rod support part extends, so the peripheral material can prevent stones, branches, etc. from scattering around. Also, since at least a part of the peripheral material is in contact with the ground, the peripheral material can prevent stones, branches, etc. from scattering around. Furthermore, since the peripheral material has flexibility, deterioration caused by the grass cutting part coming into contact with it can be prevented.

[0016] According to this configuration, since the rod support portion is provided near the through hole, the length of the rod support portion can be set to be short. As a result, when the grass cutting unit moves inside the protective cover, it can move smoothly without interfering with the rod support portion. In addition, since the rod support portion is provided on the upper part of the protective cover, damage to the grass cutting unit caused by contact with the rod support portion can be avoided.

[0017] With this configuration, the weeding work is performed with the support part supporting the rod part, so that the protective cover can be prevented from being unstable and shaking due to the vibration caused by the rotation of the grass cutting part. As a result, the protective cover is stabilized, so that gaps between the cover and the ground are less likely to occur, and stones, branches, etc. can be effectively prevented from scattering into the surrounding area. Furthermore, the rod part is inserted into the through hole formed in the support part, so that damage to the through hole caused by the rod part shaking can be avoided.

[0018] With this configuration, the auxiliary telescopic part supports the rod part, stabilizing the protective cover and preventing the protective cover from swinging due to vibrations from the grass cutting part. This makes it difficult for gaps to form between the protective cover and the ground, effectively preventing stones, branches, etc. from scattering around.

[0019] The present invention makes it possible to provide a scattering prevention cover and a brush cutter equipped with a scattering prevention cover that can prevent stones, grass, etc. from scattering into the surrounding area and can also efficiently cut weeds along walls.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] A scattering prevention cover 1 detachably attached to a brush cutter 10 according to a first embodiment of the present invention will be described with reference to Figures 1 to 6. As shown in the figures, front, rear, up, down, left and right directions are defined.

[0022] As shown in Figure 1, the brush cutter 10 cuts grass at the periphery with a nylon cord cutter 13 of a grass cutting part 12 that is detachably attached to the tip of a rod part 11. A drive source (not shown) is provided on the side of the rod part 11 opposite to the side where the grass cutting part 12 is provided. An operator holds a grip part 14 located at the rear of the rod part 11 and performs grass cutting work with the brush cutter 10.

[0023] As shown in FIG. 3, a fixing part 15 is provided at approximately the center of the rod part 11. By releasing the fixing part 15, the rod part 11 can be separated into a first rod part 11A to which the grass cutting part 12 is provided and a second rod part 11B to which the grip part 14 is provided. The rod part 11 and the grass cutting part 12 are configured to be detachable by removing a fixing bolt (not shown). The driving source (not shown) may be a battery or diesel powered power source attached to the end of the rod part 11, and may be a type that is carried on the back. The grass cutting part 12 may be provided with a metal cutting blade instead of the nylon cord cutter 13.

[0024] As shown in Figures 1 and 2, the scattering prevention cover 1 is composed of a protective cover 2, a rod support part 3, and a peripheral material 4. The protective cover 2 is substantially dome-shaped and composed of a metal mesh so that the inside can be seen, and covers the entire upper and side parts of the grass cutting part 12. A substantially cylindrical tubular part 21 is provided at the upper part of the protective cover 2, and a through hole 22 into which the rod part 11 is inserted is formed at the rear part of the protective cover 2.

[0025] The cylindrical portion 21 is provided so that its center is substantially aligned with the protective cover 2, and serves to increase the rigidity of the protective cover 2. The through hole 22 is formed so as to open in an obliquely upward rear direction, and has a diameter sufficient for the first rod portion 11A to be inserted and moved, as shown in FIG. 3. The periphery of the through hole 22 is provided with a crimping member (not shown) to prevent the mesh from fraying. The through hole 22 is formed with a notch 22a facing downward, and a clip 23 is provided for fixing the notch 22a. By opening the clip 23 to open the notch 22a, the scattering prevention cover 1 can be applied to rod portions 11 and grass cutting portions 12 of various shapes. The periphery of the notch 22a is provided with a reinforcing material 22A for preventing fraying. The position at which the through hole 22 is formed can be set arbitrarily according to the angle of the rod portion 11, etc.

[0026] 6, the protective cover 2 has an inner diameter that brings the nylon cord cutter 13 and the peripheral material 4 into close proximity when the grass cutting unit 12 is disposed substantially in the center of the protective cover 2 and the nylon cord cutter 13 is driven. In other words, the inner diameter of the protective cover 2 is set to be larger than the diameter of the nylon cord cutter 13 during rotation. This makes it possible to prevent the nylon cord cutter 13 and the peripheral material 4 from constantly coming into contact with each other, reduce noise during operation, and suppress wear on the peripheral material 4 and the nylon cord cutter 13.

[0027] The rod support part 3 is a member for fixing the rod part 11 or the grass cutting part 12 to the scattering prevention cover 1, and is provided on the upper part of the protective cover 2 and in the vicinity of the through hole 22, as shown in Fig. 2. The rod support part 3 is composed of a cover fixing part 31, an expandable part 32, and a rod fixing part 33. As shown in Fig. 4, the cover fixing part 31 is a member for fixing the expandable part 32 to the protective cover 2, and is composed of a pair of mounting collars 34, a bolt 35, and a nut 36. The mounting collars 34 are provided so as to sandwich the protective cover 2 from above and below, and the bolt 35 and the nut 36 are inserted through them.

[0028] As shown in Fig. 5, the expandable part 32 is a rubber tube having a substantially flat plate shape, and an opening 32a is formed at one end. A crimped part 37 is provided around the periphery of the opening 32a to prevent cracks. It is desirable to set the thickness of the expandable part 32 so that it can expand and contract to such an extent that the grass cutting part 12 can move within the protective cover 2. The other end of the expandable part 32 is fixed to the rod fixing part 33.

[0029] As shown in Fig. 6, the extendable portion 32 is set to a length that is sufficiently extended when the grass cutting unit 12 moves to the vicinity of the peripheral material 4 on the protective cover 2. In other words, when the protective cover 2 abuts against the wall 100 and cannot move forward, and the operator presses the grass cutting unit 12 against the wall 100 by further advancing the gripping portion 14, the extendable portion 32 is set to a length that prevents the grass cutting unit 12 from moving any further forward in a state in which the grass cutting unit 12 is in proximity to or in contact with the peripheral material 4. In the cover fixing portion 31, the bolt 35 passes through the opening 32a surrounded by the crimping portion 37 and is fixed to the mounting collar 34 by the nut 36, thereby fixing the extendable portion 32 to the protective cover 2.

[0030] The grass cutting unit 12 can move within the protective cover 2 from the position indicated by the solid line to the position indicated by the dotted line in Fig. 6. In other words, the grass cutting unit 12 moves within the protective cover 2 so that the nylon cord cutter 13 can completely cut the weeds on the ground G within the protective cover 2. This makes it possible to cut even weeds located in the gap S near the wall 100 and indicated by the dashed line in the figure. At this time, since the peripheral material 4 is located between the wall 100 and the nylon cord cutter 13, damage to the wall 100 by the nylon cord cutter 13 can be prevented.

[0031] The rod fixing portion 33 has an insertion hole 33a formed therein, and the rod portion 11 or the grass cutting portion 12 is passed through the insertion hole 33a and fixed to the rod portion 11 or the grass cutting portion 12 with a fixing bolt 33A.

[0032] The peripheral material 4 is provided on the lower part of the protective cover 2 and is made of rubber having a predetermined thickness. The peripheral material 4 has a substantially flat plate shape when unfolded, and is provided around the entire periphery of the protective cover 2. The peripheral material 4 is fixed to the protective cover 2 by a plurality of bolts 41. As shown in FIG. 2, the lower end of the peripheral material 4 abuts or is close to the ground G around the entire periphery. In other words, the grass cutting part 12 and the nylon cord cutter 13 are covered in all directions, including front, back, up, down, left and right, by the protective cover 2 and the peripheral material 4.

[0033] Next, a method for attaching the scattering prevention cover 1 to the brush cutter 10 will be described with reference to FIG.

[0034] As shown in Fig. 3(a), the fixing part 15 of the brush cutter 10 is released, and the rod part 11 is separated into the first rod part 11A and the second rod part 11B. At the same time, the bolts (not shown) that secure the rod part 11 and the grass cutting part 12 are removed to separate them. As shown in Fig. 3(b), the grass cutting part 12 is placed inside the protective cover 2. At this time, the grass cutting part 12 may be completely covered by the protective cover 2, or a part of the grass cutting part 12 may be exposed to the outside through the through hole 22.

[0035] As shown in Fig. 3(c), the rod portion 11 is inserted into the insertion hole 33a with the protective cover 2 covering the grass cutting part 12. At this time, the clip 23 is removed and the cut 22a is opened, so that the rod portion 11 can be easily inserted into the through hole 22. The rod portion 11 and the grass cutting part 12 are fixed to each other, and the rod fixing part 33 is fixed to the rod portion 11 or the grass cutting part 12 by the fixing bolt 33A. The first rod portion 11A and the second rod portion 11B are connected and fixed by the fixing part 15, and thus the attachment of the scattering prevention cover 1 to the brush cutter 10 is completed.

[0036] According to this configuration, the rod portion 11 can move through the through hole 22 and the rod support portion 3 has elasticity, so that the grass cutting portion 12 can move within the protective cover 2. As a result, the gap S between the grass cutting portion 12 and the protective cover 2 is eliminated, so that the weeds located in the gap S can also be removed. In the conventional scattering prevention cover, the scattering prevention cover and the rod were fixed so as not to move, so that it was difficult to completely remove the weeds near the wall. In contrast, in the scattering prevention cover 1 of the present invention, the grass cutting portion 12 can move within the scattering prevention cover 1, so that the weeds near the wall 100 can be removed without leaving any weeds behind, as shown in FIG. 6. In addition, since the protective cover 2 covers the upper and side portions of the grass cutting portion 12, scattering of stones, branches, etc. to the surroundings can be suppressed.

[0037] According to this configuration, the peripheral material 4 comes into contact with the grass cutting part 12 as the telescopic part 32 of the rod support part 3 extends, so that the peripheral material 4 can prevent stones, branches, etc. from scattering into the surroundings. Also, because at least a part of the peripheral material 4 comes into contact with the ground G, the peripheral material 4 can prevent stones, branches, etc. from scattering into the surroundings. Furthermore, because the peripheral material 4 has flexibility, deterioration due to contact with the grass cutting part 12 can be suppressed.

[0038] With this configuration, since the rod support part 3 is provided near the through hole 22, the length of the extension part 32 of the rod support part 3 can be set short. As a result, when the grass cutting part 12 moves inside the protective cover 2, it can move smoothly without interfering with the extension part 32. In addition, since the rod support part 3 is provided on the upper part of the protective cover 2, damage to the grass cutting part 12 caused by contact with the extension part 32 can be avoided.

[0039] Next, a second embodiment of the present invention will be described with reference to Fig. 7. The same components as those in the first embodiment are given the same reference numerals and the description thereof will be omitted.

[0040] The shatterproof cover 101 according to the second embodiment is composed of a protective cover 2 and a rod support portion 3. Unlike the shatterproof cover 1 according to the first embodiment, the shatterproof cover 101 is not provided with a peripheral material 4. In other words, the bottom of the protective cover 2 abuts or is close to the ground G. This makes it possible to prevent stones and the like from scattering due to the rotation of the nylon cord cutter 13, and also makes it possible to reduce the manufacturing cost of the shatterproof cover 1.

[0041] Next, a third embodiment of the present invention will be described with reference to Fig. 8. The same components as those in the above-mentioned embodiment are given the same reference numerals and the description thereof will be omitted.

[0042] In the shatterproof cover 301 according to the third embodiment, four rod support parts 303 are provided on the upper surface of the protective cover 302. A rod fixing part (not shown) is provided at the end of each of the expandable parts 332. Furthermore, the through hole 322 is not provided with the notch 22a and the clip 23.

[0043] With this configuration, the rod fixing part is supported by the multiple rod support parts 303, so the grass cutting part 12 can be moved stably within the protective cover 2. Also, because the rod fixing part is supported by the four extension parts 332, wear on the extension parts 332 can be suppressed, and the life of the scattering prevention cover 301 can be extended. Furthermore, because the notches 22a and clips 23 are omitted in the through holes 322, the manufacturing cost of the scattering prevention cover 301 can be reduced.

[0044] Next, a fourth embodiment of the present invention will be described with reference to Fig. 9. The same components as those in the above-mentioned embodiment are given the same reference numerals and the description thereof will be omitted.

[0045] The shatterproof cover 401 according to the fourth embodiment is provided with a cylindrical support part 422 on the protective cover 2. The support part 422 protrudes diagonally upward and rearward from the protective cover 2, and is formed with a support hole 422a that is larger than the rod part 11. When attaching the rod part 11 to the protective cover 2, with the grass cutting part 12 placed inside the protective cover 2, the first rod part 11A is inserted into the support part 422, and the grass cutting part 12 and the first rod part 11A are fixed together.

[0046] With this configuration, weeding work is performed with the support part 422 supporting the rod part 11, so it is possible to prevent the protective cover 2 from being unstable and shaking due to vibration caused by the rotation of the grass cutting part 12. As a result, the protective cover 2 is stabilized, so that gaps are less likely to occur between the peripheral material 4 and the ground G, and it is possible to effectively prevent stones, branches, etc. from scattering around. Furthermore, since the rod part 11 is inserted into the support hole 422a formed in the support part 422, it is possible to avoid damage to the through hole 22 caused by the rod part 11 shaking.

[0047] Next, a fifth embodiment of the present invention will be described with reference to Fig. 10. The same components as those in the above-mentioned embodiments are given the same reference numerals and the description thereof will be omitted.

[0048] The scattering prevention cover 501 according to the fifth embodiment is provided with an auxiliary telescopic part 512, one end of which is fixed to a first attachment part 511 fixed to the first rod part 11A, and the other end of which is fixed to a second attachment part 513 fixed to the protective cover 2. At least one of the first attachment part 511 and the second attachment part 513 is provided with the auxiliary telescopic part 512 in a detachable manner. When attaching the protective cover 2 to the brush cutter 10, the grass cutting part 12 is placed inside the protective cover 2 and the grass cutting part 12 and the first rod part 11A are fixed to each other, and then the auxiliary telescopic part 512 is fixed to the first attachment part 511 and the second attachment part 513.

[0049] With this configuration, the auxiliary telescopic part 512 supports the rod part 11, stabilizing the protective cover 2 and preventing an unstable state in which the protective cover 2 swings due to vibrations of the grass cutting part 12. As a result, the protective cover 2 is stabilized, making it difficult for gaps to form between the peripheral material 4 and the ground G, effectively preventing stones, branches, etc. from scattering around.

[0050] Next, a sixth embodiment of the present invention will be described with reference to Fig. 11. The same components as those in the above-mentioned embodiments are given the same reference numerals and the description thereof will be omitted.

[0051] The scattering prevention cover 601 according to the sixth embodiment is provided with two second auxiliary telescopic parts 612, one end of which is fixed to the first attachment part 511 and the other end of which is fixed to a third attachment part 613 provided on the cylindrical part 21. At least one of the first attachment part 511 and the third attachment part 613 is provided with the second auxiliary telescopic parts 612 in a detachable manner. When attaching the protective cover 2 to the brush cutter 10, the grass cutting part 12 is placed inside the protective cover 2 and the grass cutting part 12 and the first rod part 11A are fixed, and then the auxiliary telescopic parts 512 are fixed to the first attachment part 511 and the second attachment part 513, and the two second auxiliary telescopic parts 612 are fixed to the first attachment part 511 and the third attachment part 613.

[0052] With this configuration, the auxiliary telescopic part 512 and the second auxiliary telescopic part 612 support the rod part 11, making the protective cover 2 more stable and preventing an unstable state in which the protective cover 2 swings due to vibrations of the grass cutting part 12. As a result, the protective cover 2 is stabilized, making it difficult for gaps to form between the peripheral material 4 and the ground G, and more effectively preventing stones, branches, etc. from scattering around.

[0053] The anti-scattering cover and the brush cutter equipped with the anti-scattering cover according to the present invention are not limited to the above-described embodiment, and various modifications are possible within the scope of the gist of the invention described in the claims.

[0054] In the above embodiment, the protective cover 2 has a substantially dome-shaped circular cross section, but is not limited to this. Any protective cover 2 that completely covers the grass cutting unit 12 may have a rectangular or polygonal cross-sectional shape. In addition, the protective cover 2 is made of a metal mesh material, but is not limited to this and may be made of a transparent resin or punched metal that allows the inside to be seen.

[0055] In the above-described embodiment, a cylindrical rubber tube is used as the expandable part 32, but this is not limited thereto. The expandable part 32 may be a substantially flat rubber plate, and may be made of natural rubber, butyl rubber, chloroprene rubber, urethane rubber, silicone rubber, nitrile rubber, ethylene propylene rubber, fluororubber, or the like, so long as the expandable part 32 has sufficient expandability to allow the grass cutting part 12 to move within the protective cover 2.
