Description

Technology Field

[0001] The present invention relates to an auxiliary stand for a brush cutter, and more specifically, to an auxiliary stand for a brush cutter that allows the brush cutter to be mounted to perform brush cutting work comfortably. Background Technology

[0003] In general, brush cutters are widely used as automated tools to effectively remove weeds, grass, or shrubs and vines growing low on the ground.

[0004] Such a brush cutter is composed of a power unit consisting of a 2-cylinder or 4-cylinder engine with a shoulder strap attached so that it can be carried on the shoulder, a connecting pipe for transmitting driving force from the power unit, a grip handle mounted on the connecting pipe, and a head including a cutter rotatably mounted on the lower end of the connecting pipe.

[0005] Furthermore, brush cutters utilize metal cutters, nylon cutters, etc. While metal cutters are effective for removing small-diameter branches and cutting weeds, they can be damaged if they collide with tree stumps, rocks, or stones during cutting. This often results in flying fragments that cause safety accidents.

[0006] Recently, taking this into account, wire cutters made of synthetic resin are widely used when cutting relatively soft grass, such as weeds or grass, rather than thick branches. However, even with such wire cutters, there are inconveniences, such as the need for frequent replacement because they wear out easily.

[0007] Usually, when mowing, the operator works with the mower head equipped with a cutter lifted to a certain height above the ground. In this case, moving the mower around is unstable and requires a lot of force, and the work speed is slow. Furthermore, the heavy mower has the disadvantage of requiring significant physical exertion from the operator.

[0008] In addition, there is a disadvantage in that the quality of the mowing work cannot be ensured, such as the inability to mow at a uniform height, because it is difficult to perform the work while consistently maintaining the height of the mower head. Prior art literature

Specific details for implementing the invention

[0027] The present invention will be described in detail below with reference to the attached drawings.

[0028] FIGS. 1 and FIGS. 2 are perspective views showing an auxiliary holder for a brush cutter according to one embodiment of the present invention, and FIG. 3 is a cross-sectional view showing an auxiliary holder for a brush cutter according to one embodiment of the present invention.

[0029] As illustrated in FIGS. 1 to 3, the auxiliary holder for the brush cutter includes a holder body (12) as a means for holding the brush cutter.

[0030] The above-mentioned mounting body (12) is in the form of a triangular frame structure, and on both sides of the lower part, a wheel mounting part (10) in the form of a square hole is formed with the front and / or rear sides open, and on the center of the upper part, a block mounting groove (11) is formed with the top open and in the form of a semicircular groove.

[0031] Here, as holes (not shown in the drawing) for fastening coupling pins (not shown) are formed in the front and side of the wheel mounting part (10), the wheel support (13) inserted into the wheel mounting part (10) can be supported by coupling pins fastened from the front or side.

[0032] At this time, the wheel support (13) can be inserted into the wheel mounting part (10) and supported with the support shaft (26) facing sideways, so that the wheel (14) coupled to the support shaft (26) can also take a rolling direction toward the front or the back, or the wheel (14) coupled to the support shaft (26) can be inserted into the wheel mounting part (10) and supported with the support shaft (26) facing forward or the back, so that the wheel (14) coupled to the support shaft (26) can also take a rolling direction toward the sideways.

[0033] And, a brush cutter tilting block (16) is inserted into the above block mounting groove (11), and the brush cutter tilting block (16) can be supported in a structure that allows it to tilt left and right through the connection of a central axis pin (15) via a bushing (22).

[0034] Wheel supports (13) are installed on both wheel mounting parts (10) of the main body (12) of the stand, and wheels (14) are installed on the wheel supports (13) installed in this way, so that a total of two wheels (14) can be installed, one on each side of the lower part of the main body (12).

[0035] That is, the wheel support (13) is formed in the shape of a square block having a horizontal support shaft (26) on the side of the lower part, and the wheel support (13) is installed in a structure that is inserted into the wheel mounting part (10) in the main body (12) of the stand and supported by fastening a coupling pin, and the wheel (14) is installed in a structure that is fitted onto the support shaft (26) of the wheel support (13), so that the wheel (14) can be installed on both sides of the lower part of the main body (12).

[0036] Accordingly, the above-mentioned mounting body (12) can be moved using the wheel (14), and at the same time, the wheel (14) can be tilted forward and backward around the support axis (26) of the wheel support (13) into which the wheel (14) is fitted, and consequently, through this tilting operation of the mounting body (12), the brush cutter mounted on the mounting body (12) can also be tilted forward and backward.

[0037] At this time, a snap ring (not shown) is fastened to the joint between the support shaft (26) and the wheel (14) to prevent the wheel (14) from coming off.

[0038] In particular, the wheel mounting portion (10) formed on the mounting body (12) may be formed as a pair located at the front and rear of the mounting body (12), for example, among the wheel mounting portions (10) on both sides of the mounting body (12), the wheel mounting portion (10) on one side may be formed as a pair located at the front and rear of the mounting body (12).

[0039] Accordingly, both wheels (14) can be installed and used on either wheel mounting part (10) of the two wheel mounting parts (10) of the main body (12).

[0040] That is, the wheel (14) in one wheel mounting part (10) is removed, and the removed wheel (14) is installed in the front of the pair of wheel mounting parts (10), so that the wheels (14) are installed in the front and rear of the pair of wheel mounting parts (10), and eventually, both wheels (14) can be installed in one wheel mounting part (10) of the stand body (12) and used.

[0041] At this time, the two wheels (14) installed on one side of the above-mentioned mounting body (12) can be installed so as to face the longitudinal direction of the brush cutter body (12) (e.g., a direction that forms a 90° right angle with respect to the front and rear direction of the brush cutter body).

[0042] In this way, since two wheels (14) can be installed on one side of the stand body (12) and used, that is, since the width between the two wheels (14) can be made relatively narrower than the width between the wheels (14) installed on both sides of the stand body (12), there is an advantage in that crop harvesting or weed removal work can be easily performed while moving between narrow furrows with the wheels (14).

[0043] In addition, the auxiliary stand for the brush cutter includes two wheels (14) as a means for moving the stand body (12).

[0044] The wheel (14) serves to move the entire mounting body (12), including the brush cutter, back and forth, and is installed in a detachable structure on the wheel mounting part (10) of the mounting body (12) using a wheel support (13).

[0045] That is, the wheel (14) is installed in a structure that allows it to rotate around the support shaft (26) of a wheel support (13) installed in the wheel mounting part (10) of the main body (12), and accordingly, the wheel (14) can be attached to and detached from the main body (12) together with the wheel support (13), and consequently, the wheels (14) on both sides can be used in a state where one wheel is installed on each side of the main body (12), or where both wheels are installed on one side of the main body (12).

[0046] In addition, the auxiliary holder for the brush cutter includes a brush cutter tilting block (16) as a means to enable the left and right tilting of the brush cutter.

[0047] The above-mentioned brush cutter tilting block (16) is formed in a combined form of an upper disc that takes a horizontal position and a lower cylindrical block that takes a vertical position and faces the front and rear directions.

[0048] The brush cutter tilting block (16) is installed in a structure in which it is fitted into a block mounting groove (11) with an open top formed in the upper part of the mounting body (12), for example, a block mounting groove (11) having a semicircular inner surface that enables left and right sliding movement of the cylindrical block while being fitted with the cylindrical block of the brush cutter tilting block (16), and is coupled with a central axis pin (15) that horizontally penetrates the upper part of the mounting body (12) and the brush cutter tilting block (16) along the front and rear directions.

[0049] The brush cutter tilting block (16) installed in this way can be tilted left and right while rotating around the central axis pin (15), and as a result, the entire brush cutter including the brush cutter holder (18) can be tilted left and right according to the left and right tilting operation of the brush cutter tilting block (16) to perform the brush cutter work.

[0050] In addition, the above-mentioned brush cutter tilting block (16) has a shaft groove (27) formed therein that is dug to a certain depth from the top, so that a brush cutter rotation shaft (17) can be inserted and installed therein, and in addition, on the top surface of the brush cutter tilting block (16), that is, on the top surface of the disc, a plurality of hemispherical ball holes (21), for example, four hemispherical ball grooves (21) arranged at 90° intervals are formed therein so that a ball (19) can be seated and installed therein.

[0051] In addition, the auxiliary stand for the brush cutter includes a brush cutter rotation shaft (17) as a means for performing the role of a rotational center axis of the entire brush cutter, including a brush cutter holder (18).

[0052] The above-mentioned brush cutter rotation shaft (17) is installed in a structure in which its lower end is vertically fitted into a shaft groove (27a) formed in the upper part of the brush cutter tilting block (16), and the brush cutter rotation shaft (17) installed in this way has its upper end protruding upward, and at the same time, the shaft groove (27b) in the brush cutter holder (18) can be fitted into the protruding upper end.

[0053] The brush cutter rotation shaft (17) is connected in a rotatable structure with respect to the brush cutter tilting block (16) side, and at the same time is connected integrally with respect to the brush cutter holder (17) side, so that the brush cutter holder (17) can rotate 360° in a horizontal plane with the vertical axis of the brush cutter rotation shaft (17) as the central axis together with the brush cutter rotation shaft (17).

[0054] In addition, the auxiliary stand for the brush cutter includes a brush cutter holder (18) as a means for mounting the brush cutter.

[0055] The above brush cutter holder (18) is formed as an integrated combination of a circular pressure piece (23) into which a brush cutter rod is inserted and two wing pieces (24) that tighten the pressure piece (23).

[0056] And, the pressure piece (23) of the brush cutter holder (18) is opened in the front and rear directions, and the wing piece (24) is spread out to both sides. Accordingly, the brush cutter rod is inserted into the pressure piece (23), and the pressure piece (23) can be closed by fastening bolts and nuts to the wing pieces (24) on both sides, and the brush cutter rod inserted into the pressure piece (23) can be firmly fixed.

[0057] This brush cutter holder (18) is installed in a structure that is supported by a brush cutter tilting block (16) using a brush cutter rotation shaft (17).

[0058] To this end, an axle groove (27b) is formed in the bottom portion of the brush cutter holder (18), and the upper portion of the brush cutter rotation shaft (17) is fitted into the axle groove (27b) and coupled.

[0059] Accordingly, the above-mentioned brush cutter holder (18) can rotate 360° along a horizontal plane using the brush cutter rotation shaft (17) as the rotation center axis, together with the brush cutter rotation shaft (17), and consequently, the brush cutter can also rotate 360° by the rotation operation of the brush cutter holder (18).

[0060] In a preferred embodiment, a plurality of pressure protrusions (25) for tightly securing the brush cutter rod are formed protruding from the inner surface of the brush cutter holder (18), that is, the inner surface of the pressure piece (23). Accordingly, when the pressure piece (23) is tightened by the wing piece (24), the pressure protrusions (25), which are arranged at regular intervals along the inner surface of the pressure piece, press the outer surface of the brush cutter rod, thereby allowing the brush cutter rod to be pressed evenly over the entire outer surface and tightly secured within the brush cutter holder (18).

[0061] Additionally, the auxiliary holder for the brush cutter includes a ball (19) and a spring (20) as means to guide the rotation of the brush cutter holder (18) and fix the rotated position of the brush cutter holder (18).

[0062] Here, it is preferable to have about two sets of the ball (19) and spring (20) arranged at 180° intervals.

[0063] The ball (19) and spring (20) are installed between the upper surface of the brush cutter tilting block (16) and the lower surface of the brush cutter holder (18), and serve to guide the rotation of the brush cutter holder (18) and to hold the position of the brush cutter holder (18).

[0064] To this end, a plurality of spring grooves (28) are formed along the periphery of the shaft groove (27b) on the bottom surface of the brush cutter holder (18), and a spring (20) is inserted and seated therein. At the same time, a ball (12) comes into contact with the lower end of the spring (20), and the ball (12) is seated in a plurality of ball grooves (21) formed on the upper surface of the brush cutter tilting block (16), for example, four ball grooves (21) arranged at 90° intervals.

[0065] Accordingly, when the brush cutter holder (18) is rotated, each ball (19) moves up and down while compressing the spring (20), and exits the ball groove (21) currently in place and enters the next ball hole (21) to be settled. The ball (19) that enters the ball groove (21) receives the elastic force of the spring (20) and elastically supports the upper and lower brush cutter holder (18) and the brush cutter tilting block (16) up and down, thereby allowing the rotational position of the entire brush cutter including the brush cutter holder (18) to be maintained in an adjusted state.

[0066] In this way, by using the ball (19) and spring (20) to fix the position of the brush cutter and perform the mowing work, there is an advantage that the worker can easily perform the mowing work without the inconvenience of having to manually adjust the position of the brush cutter each time.

[0067] FIG. 4 is a side view showing the state of use of an auxiliary holder for a brush cutter according to one embodiment of the present invention, with the brush cutter mounted thereon.

[0068] As shown in FIG. 4, the state in which a brush cutter (100) is mounted on an auxiliary stand for a brush cutter is shown here.

[0069] That is, after inserting the brush cutter pole of the brush cutter (100) into the brush cutter holder (18) of the auxiliary stand for the brush cutter, and then tightening the bolt and nut on the wing section (24) of the brush cutter holder (18), the brush cutter (100) can be firmly fixed to the brush cutter holder (18).

[0070] In this state, if you push the brush cutter (100) around using the wheel (14) to perform the brush cutting work, you can perform the brush cutting work easily without much effort.

[0071] At this time, the brush cutter (100) can perform a brush cutting operation while tilted appropriately forward together with the brush cutter body (12).

[0072] FIG. 5 is a front view showing the state of use of an auxiliary holder for a brush cutter according to one embodiment of the present invention, which is a state of performing oxygen mowing work.

[0073] As shown in FIG. 5, the state of mowing the oxygen, etc., is shown here with the mower (100) fixed to the mower holder (18).

[0074] That is, when the brush cutter (100) is tilted to the left or right, the brush cutter holder (18) and the brush cutter tilting block (16) rotate around the central axis pin (15) and tilt to the left or right, and eventually the brush cutter (100) is also tilted to the left or right, so that the brush cutter (100) can be tilted in this way to facilitate brush cutting work on a round surface such as oxygen.

[0075] FIG. 6 is a plan view showing the state of use of an auxiliary holder for a brush cutter according to one embodiment of the present invention, which is a state of performing crop harvesting work in furrows.

[0076] As shown in FIG. 6, this shows the state of harvesting crops in a field or removing bushes or weeds in a field with both wheels (14) installed on one side of the stand body (12).

[0077] That is, after separating the wheel (14) and wheel support (13) on one side of the brush cutter body (12), they are installed side by side with the wheel (14) on the other side of the brush cutter body (12).

[0078] At this time, two wheels (14) are installed so as to face the longitudinal direction of the brush cutter body (12) (e.g., a direction that forms a 90° right angle with respect to the front and rear direction of the brush cutter body).

[0079] In this state, by moving the two wheels (14) along the narrow furrows, the mower (100) can be used to easily perform mowing work such as harvesting crops between the furrows or removing weeds.

[0080] Thus, the present invention provides a new auxiliary stand for a brush cutter that allows the brush cutter to be mounted during mowing operations, as well as to be tilted left and right or rotated in various directions to perform mowing operations. This enables the brush cutter to be easily and effortlessly performed, and at the same time, the brush cutter can be tilted left and right or rotated 360°, making it easy to perform tasks such as mowing and harvesting crops in furrows.
