Support device for mowers {Support Device for Weed Cutter}

The present invention relates to a support device for mowers. More specifically, the rotary cutter of the mower can be easily detached from the ground and can be easily attached and detached to the mower's work support bar without a separate tool, and the arrangement state and height of the support unit supporting the rotary cutter away from the ground And the width can be easily adjusted without a separate tool in one-touch method, it is possible to extend the application range of the lawn mower to a variety of working environment, equipped with a separate guide unit to protect the rotary cutter of the lawn mower and a specific tree when mowing The present invention relates to a mower support device that can protect a back and facilitate harvesting of crops.

Conventionally, working with a sickle is used for harvesting or cutting grass such as soybeans, sesame seeds, rice, and corn in a cultivated field, or for cutting grass such as gardens and graveyards. It is cumbersome and time consuming, and recently, a portable mower using an engine or a motor has been developed and widely used.

FIG. 1 is a perspective view schematically showing a configuration of a general lawn mower. As shown in FIG. 1, a general lawn mower 1 includes a power unit 2 mounted with a motor or an engine and carried by a user on the back, and a power unit ( 2) is made of a rotary cutter portion 4 for transmitting power of 2) to cut grass or grass on the ground, and a work support rod 3 having a constant diameter connecting the rotary cutter portion 4 and the power unit 2 to each other. In the rotary cutter unit 4, various types of rotary cutters 5 having different rotation radii are interchangeably mounted.

The mowing operation using such a mowing machine works by holding the power support 2 of the mowing machine 1 on the user's back and holding the work support rod 3 with both hands, while rotating cutter 5 attached to the tip of the work support rod 3. ) Should be kept spaced apart from the ground so that it does not touch the ground.

However, even in this operation, even a skilled worker is affected by the weight of the rotary cutter unit 4 and the work support rod 3 and the vibration of the work support rod 3 by the power unit 2. It is very difficult to keep them in a horizontal position, which is why it is not only very careful to mow the grass, but when the rotary cutter hits the ground during the operation, the blade of the rotary cutter is broken or the stone on the ground is scattered. There could be a problem causing a lot of physical and mental fatigue.

In addition, when a non-skilled person trims the lawn such as a garden through such a mower, the height of the lawn to be mowed is not uniform, and thus hurts the beauty of the lawn. There was a problem.

In addition, such a lawnmower is not suitable for harvesting crops, which are not scattered in all directions without being laid down in a certain direction when cutting crops such as soybeans, sesame seeds, rice, and corn for harvesting purposes in a small farmland. In the case of cutting grass, the cut grass is scattered in all directions and is caught in the rotating portion of the rotary cutter, thereby stopping the rotation of the rotary cutter or causing a breaker.

Recently, as a way to solve some of these problems, a support device for mowers has been developed to keep the height of the rotary cutter constant. Such a mower support device is generally coupled to a mower support rod, etc., and is coupled through a very rigid fixing method so as not to be easily detached from the mower by vibration or shock during operation. Therefore, once the support device for the lawn mower is mounted once on the lawn mower, it is difficult to separate from the lawn mower afterwards, so that the lawn mower must be used while the support device is still mounted. For this reason, the mowing operation may be more inconvenient or even impossible by the mower support device in certain working environments, which not only greatly limits the convenient functions of the mower, which can be applied to various working environments, but also increases the weight and volume of the mower. There was a problem such as not easy to transport and storage.

2 is a perspective view schematically showing a shape in which a lawnmower support apparatus is mounted on a lawnmower according to an embodiment of the present invention, and FIG. 3 is a configuration of a fixing unit of the lawnmower support apparatus according to an embodiment of the present invention. Figure 4 is an exploded perspective view schematically showing, Figure 4 is a side view schematically showing the operating state of the fixed unit of the lawn mower support apparatus according to an embodiment of the present invention.

The lawn mower support device according to an embodiment of the present invention has a structure capable of easily detaching and performing various functions at the same time as a one-touch operation method to the work support rod of the lawn mower, as shown in FIG. 2. A fixed unit 100 coupled to the work support rod 3, a support unit 400 for separating the rotary cutter 5 of the lawn mower from the ground, and an agent for tightly coupling the fixed unit 100 to the work support rod 3. It comprises a 1 QR lever module 200.

The fixed unit 100 is configured to securely couple the support device for the lawn mower to the work support rod 3 of the lawn mower, and is coupled to the lower end of the work support rod 3 as shown in FIG. It is elastically pressurized by the 200 is configured to surround the outer circumferential surface of the work support bar (3) to be in close contact.

The support unit 400 is coupled to the fixed unit 100 and the lower end of the support unit 400 is coupled to the fixed unit 100 so that the rotary cutter 5 can be spaced apart from the ground by a predetermined distance. It is located lower than (5) and formed to be in contact with the ground. By the support unit 400, the mower user is supported on the ground through the support unit 400 without having to lift the work support rod 3 at a predetermined distance to separate the rotary cutter 5 from the ground during mowing. The mowing operation can be carried out easily.

The first QR lever module 200 elastically pressurizes the fixing unit 100 to closely couple the fixing unit 100 to the outer circumferential surface of the working support rod 3, or elastically release the fixing unit 100 to release the working support rod ( It is configured to release the close coupling from the outer peripheral surface of 3). The first Ql lever module 200 is configured to be fastened and released quickly and easily by a simple operation of a user without a separate tool in a quick lever method that operates through a lever movement. Therefore, the fixing unit 100 can be easily detached to the working support bar 3 without a separate tool through the first QR lever module 200.

According to this configuration, the lawn mower support device according to the embodiment of the present invention can be easily detached to the lawn mower through a simple operation of the user without a separate tool. Therefore, since the support device can be easily detached or recombined from the mower without a separate tool according to the working environment during mowing, the application range of the mower can be further extended. In addition, since the support device can be quickly and easily detached from the mower, the carrying and storage of the mower can also be carried out more conveniently.

Looking at the configuration of the support device for the lawn mower in more detail, first, the fixing unit 100 may be formed separately from the first and second fixing plates 110 and 120, as shown in Figure 3, the first and second fixing plates 110 and 120 are each bent to be in contact with the outer circumferential surface of the work support bar (3) and to be hinged to be rotatably coupled to each other about a hinge axis (130) in a direction parallel to the longitudinal direction of the work support bar (3) Can be. Accordingly, the first and second fixing plates 110 and 120 rotate about the hinge shaft 130 and are elastically pressed by the first QL lever module 200 in contact with the outer circumferential surface of the work support rod 3 and the work support rod ( It is tightly coupled to the outer circumferential surface of 3).

At this time, the first QR lever module 200 generates a fastening force in a direction in which the first fixing plate 110 and the second fixing plate 120 are pivotally pressed from the outside to the inside, as shown in FIG. 3. 2 A first rod bolt 210 having a male thread S formed at one end of the outer circumferential surface of the fixed plate 110 and 120 at the same time and a male thread S of the first rod bolt 210 formed at one end thereof. The first fixing nut 220, which is screwed, the first fixing block 230 penetratingly coupled to the other end of the first rod bolt 210, and a direction perpendicular to the length direction of the first rod bolt 210, One end portion is rotatably coupled to the other end of the first rod bolt 210 so as to rotate about the first operating shaft 211 is configured to include a first operating lever (240). In this case, the first fixing nut 220 is disposed outside the first fixing plate 110, the first fixing block 230 is disposed outside the second fixing plate 120, and the first fixing block 230 is It is configured to linearly move in the longitudinal direction of the first rod bolt 210 in conjunction with the rotation of the first operating lever 240.

Therefore, when the first operating lever 240 rotates in one direction about the first operating shaft 211, the first fixing block 230 moves linearly in association with the first operating block 211. And a relative distance between the first fixing nut 220 and the first fixing nut 220 decreases, and thus the first fixing plate 110 and the second fixing plate 120 positioned between the first fixing block 230 and the first fixing nut 220. Is pressed in a relatively closer direction. According to this operating principle, the first fixing plate 110 and the second fixing plate 120 are elastically pressed toward the work support rod 3 and are closely coupled to the outer circumferential surface of the work support rod 3. On the contrary, when the first operating lever 240 rotates in the opposite direction, the first fixing block 230 moves in reverse to release the elastic pressing against the first fixing plate 110 and the second fixing plate 120.

In this case, the interlocking relationship between the rotation of the first operating lever 240 and the first fixing block 230 may be configured in such a manner that the rotation center of the first operating lever 240 is eccentrically positioned. That is, as shown in the enlarged view of FIG. 4, the distance from the first actuating shaft 211 to the outer circumferential surface of the first actuating lever 240 is greater than L2 so that the first actuating lever 240 rotates. In this case, the first fixing block 230 may be linearly moved by a distance of L2-L1.

The first QR lever module 200 is a structure that can exert a strong fastening force through a relatively small force, since the first operating lever 240 is a lever movement around the first operating shaft 211, in addition to It may be changed in various ways.

According to such a configuration, since the fixing unit 100 is formed by being hinged by being separated into the first and second fixing plates 110 and 120, the lawn mower support device according to the embodiment of the present invention may have the shape of the work support rod 3. Regardless of the size, all can be coupled to various kinds of working support rods (3).

Meanwhile, as shown in FIGS. 3 and 4, the fixing unit 100 is rotatably mounted to one end of the first fixing plate 110 so as to rotate about a rotation axis parallel to the hinge axis 130. Block 140 may further comprise. A coupling hole 141 penetrated in a direction perpendicular to the rotation axis may be formed in the central portion of the rotating block 140, and one end of the first rod bolt 210 may be inserted and coupled to the coupling hole 141.

According to this configuration, since the first rod bolt 210 may be coupled with the rotation block 140 and rotated as shown in FIG. 4, the first and second fixing plates 110 and 120 are fastened to the work support rod 3. Whenever it is possible to operate in a state coupled to the rotary block 140 of the first fixing plate 110 without having to remove the first QR lever module 200 from the fixing unit 100. That is, when the first actuating lever module 200 is rotated downward together with the rotating block 140 as shown in FIG. 4 in the state in which the first operating lever 240 is rotated in the direction of releasing the fastening, the first fixing plate ( Since the fixing state of the 110 and the second fixing plate 120 is released, the fixing unit 100 may be separated from the working support rod 3.

On the other hand, the lawn mower support apparatus according to an embodiment of the present invention further includes a connection unit 300 for coupling and coupling the support unit 400 and the fixed unit 100 to adjust the height of the support unit 400. It can be configured, and thus, by adjusting the height of the support unit 400 when mowing, the distance between the rotary cutter 5 and the ground can be adjusted according to the working environment. Examine the configuration.

5 is an exploded perspective view schematically showing the configuration of the lawn mower support apparatus according to an embodiment of the present invention, Figure 6 is an exploded perspective view schematically showing a modified coupling structure of the support device for lawn mowers shown in FIG. 7 is an exploded perspective view schematically showing a configuration of a lawnmower support device according to another embodiment of the present invention, and FIG. 8 schematically shows a modified coupling structure of the lawnmower support device shown in FIG. 7. It is an exploded perspective view shown.

The connection unit 300 is a plurality of coupling blocks 320 arranged in the vertical direction as shown in Figures 5 to 8, and operated by a user without a separate tool to press the plurality of coupling blocks 320 up and down It is configured to include a second Q Lever module 310 to close or close the contact by pressing or releasing close. At this time, the fixing unit 100 and the support unit 400 are tightly coupled with the coupling block 320 by the second QR lever module 310, and the coupling block of the fixing unit 100 or the support unit 400 ( The height of the support unit 400 is configured to be adjusted according to the close engagement position with respect to 320.

That is, the fixed unit 100 and the support unit 400 are coupled to each other along with the connection unit 300, where the height adjustment method of the support unit 400 is coupled to the support unit 400 and the connection unit 300. By changing the coupling position of the fixing unit 100 and the connection unit 300 in a fixed position, the height of the support unit 400 can be configured as a result of adjusting the fixed unit 100 and the connection unit. It may be configured in such a way that the height of the support unit 400 is adjusted by changing the coupling position of the support unit 400 and the connection unit 300 in a fixed position of the 300. This is illustrative and also possible in other ways. For example, the fixing unit 100 coupled to the connection unit 300 and the support unit 400 may be changed at the same time to change the engagement position of the support unit 400. You can also adjust the height.

At least two or more coupling blocks 320 are disposed in a vertical direction, and a through hole 321 is formed in a central portion thereof, and the second QR lever module 310 is coupled through the plurality of coupling holes through the plurality of coupling holes. The block 320 is configured to tightly couple.

The second QR lever module 310 is configured to press the coupling block 320 in the vertical direction to be in close contact with each other, which is formed in the same manner as the first QR lever module 200. That is, the second rod bolt 311 and the second fixing nut screwed to the lower end of the second rod bolt 311 formed through the coupling block 320 at the same time in the vertical direction and the male thread (S) formed on the lower peripheral surface 312, the second fixing block 313 penetratingly coupled to the upper end of the second rod bolt 311, and the second operating shaft 315 perpendicular to the longitudinal direction of the second rod bolt 311. One end is configured to include a second operating lever 314 rotatably coupled to the other end of the second rod bolt 311 so that it can rotate to the center, the second fixing block 313 is a second operating lever ( It is configured to move in the longitudinal direction of the second rod bolt 311 in conjunction with the rotation of the 314. In this case, the second fixing nut 312 is disposed below the coupling block 320 positioned at the bottom of the plurality of coupling blocks 320, and the second fixing block 313 is positioned at the top of the plurality of coupling blocks 320. It is disposed above the coupling block 320 located.

Therefore, when the second actuating lever 314 rotates in one direction on the same principle as that of the first QR lever module 200 described above, the second fixing block 313 is in a direction close to the second fixing nut 312. Since the plurality of coupling blocks 320 are moved in the vertical direction, the plurality of coupling blocks 320 are closely coupled to each other. On the contrary, when the second actuating lever 314 rotates in the opposite direction, the second fixing block 313 moves in a direction away from the second fixing nut 312 and the close coupling state of the plurality of coupling blocks 320 is maintained. Is released. Since the second QL lever module 310 also performs the lever movement of the second actuating lever 314 about the second actuating shaft 315, it exhibits a great fastening force through a relatively small force. In this case, since the rotational operation of the second operating lever 314 and the interlocking relationship between the second fixing block 313 are configured in the same manner as the first QL lever module 200 described above, a detailed description thereof will be omitted for the purpose of overlap prevention. .

In addition, the second fixing block 313 and the second fixing nut 312 may be configured to press the coupling block 320 up and down by directly contacting the upper and lower surfaces of the coupling block 320, respectively, which will be described later. The coupling plate 150 or the connection plates 330 and 330 'may be configured to be inserted, and the detailed description thereof will be described later.

The connection unit 300 configured as described above is coupled with the fixing unit 100 and the supporting unit 400, and the coupling plate as shown in FIGS. 5 and 6 to the first fixing plate 110 of the fixing unit 100. The fixing unit 100 is protrudingly formed, and the coupling plate 150 is interposed between the coupling blocks 320 to be in close contact with the coupling block 320 by the second QR lever module 310. And the connection unit 300 may be coupled, and the height of the support unit 400 may be adjusted according to an insertion position of the coupling plate 150 with respect to the coupling block 320. At this time, the support unit 400 may also be configured in such a way that the interposed between the coupling block 320 is tightly coupled, alternatively configured in a manner that is coupled to the coupling block 320 through a separate connection case 330. May be This configuration is such that the height of the support unit 400 is adjusted as a result of the change in the engagement position of the fixed unit 100 and the connection unit 300.

In more detail, the connection unit 300 may further include a hollow pipe-shaped connection case 330 in which an accommodation space is formed so that the support unit 400 is inserted. In this case, the connection case 330 has a cutout portion 331 horizontally formed at least in one section on one side thereof, and a coupling block 320 positioned at an uppermost end of one side surface of the connection case 330 having the cutout portion 331 formed therein. Connection plates 332 which are in contact with the bottom surface of the coupling block 320 located at the top and bottom of the bottom) are respectively extended so as to be arranged in a line up and down. That is, a plurality of coupling blocks 320 are inserted between the two connecting plates 332 so that the second fixing nut 312 of the second QR lever module 310 is connected to the lower connection plate 332. The second fixing block 313 is positioned at the bottom of the upper connecting plate 332 is located.

In other words, as shown in FIG. 5, a coupling hole 333 corresponding to the through hole 321 of the coupling block 320 is formed in the connection plate 332, and the second rod bolt 311 is formed in the connection plate 332. The second fixing block 313 and the second fixing nut 312 are coupled to the upper and lower ends of the fastening hole 333 and the through hole 321, respectively. Therefore, even if the second operating lever 314 is rotated in the unlocked state, the second QR lever module 310 is not separated from the connecting plate 332 and maintains a loose coupling state. In this state, the coupling plate 150 is inserted between the coupling blocks 320. At this time, an opening slot hole 151 is formed in the coupling plate 150 in the insertion direction so that the coupling plate 150 is easily and stably between the coupling blocks 320. It is desirable to be able to be inserted.

In addition, as shown in FIG. 5, the convex embossing protrusion 152 is formed on the coupling plate 150, and correspondingly, the embossing protrusion 152 is inserted into the coupling block 320 and the connection plate 332. It is preferable that the mounting holes 322 and 334 are formed so that when the coupling plate 150 is inserted between the coupling blocks 320, the embossing protrusion 152 is seated in the inserted state even if the coupling plate 150 is inserted at any position. The insertion plate 150 is inserted into the holes 322 and 334, and is not only fixed in position, but also makes the user feel a feeling of operation, so that the coupling plate 150 may be closely coupled to the coupling block 320.

According to such a configuration, when the second QR lever module 310 is operated in the direction in which the coupling block 320 is tightly coupled by rotating the second operating lever 314, the second fixing block 313 and the second fixing are fixed. The spacing between the nuts 312 is reduced and the connection plate 332 is pressed in the vertical direction, whereby the connection plate 332 and the plurality of coupling blocks 320 are closely coupled to each other. At this time, since the coupling plate 150 of the fixing unit 100 is inserted and inserted between the specific coupling blocks 320, the coupling block 320 is operated when the second QR lever module 310 is operated. The coupling plate 150 and the connection plate 332 are all tightly coupled together. In addition, when the connection plate 332 is pressed up and down by the second QL lever module 310, the connection case 330 is also pressed in the vertical direction by the structural cutout 331 of the connection case 330, thereby The support unit 400 inserted into the connection case 330 is tightly coupled to the connection case 330.

In summary, when the second operation lever 314 is rotated in one direction, the connection plate 332 is pressed upward and downward and closely coupled to the coupling block 320 and the coupling plate 150, and at the same time, the connection case 330 is Up and down pressure is tightly coupled to the support unit 400. That is, when the second QR lever module 310 is operated in the direction in which the coupling block 320 is tightly coupled, the fixing unit 100 and the support unit 400 are tightly coupled to the connection unit 300 at the same time. On the contrary, when the second QR lever module 310 is operated in the direction in which the coupling block 320 is tightly decoupled, the fixing unit 100 and the support unit 400 simultaneously operate from the connection unit 300 according to the opposite operating principle. Uncoupling

At this time, as described above, the vertical position where the connection unit 300 and the fixing unit 100 are coupled is changed depending on a position where the coupling plate 150 of the fixing unit 100 is inserted between the coupling blocks 320. As a result, the height is adjusted from the ground of the support unit 400 coupled to the connection unit 300 as a result. According to this structure, as the number of the coupling blocks 320 increases, the insertion position of the coupling plate 150 increases, so that the height of the support unit 400 can be adjusted more precisely and in various ranges. In addition, since the maximum height adjustment range of the support unit 400 is determined according to the overall height of the plurality of coupling blocks 320, adjusting the number of coupling blocks 320 or adjusting the height of the individual coupling blocks 320 It is preferable to appropriately adjust the overall height of the coupling block 320 in accordance with the user's needs.

An example of such a height adjustment operation state is shown in FIG. 9. As shown in FIG. 9A, when the coupling plate 150 is inserted into the uppermost layer of the coupling block 320, the connection case ( The height of the support unit 400 coupled to 330 is relatively lowered to increase the separation distance between the rotary cutter 5 and the ground, as shown in (b) of Figure 9 coupling plate 150 When the insertion position is the lowest layer of the coupling block 320, the height of the support unit 400 coupled to the connection case 330 is relatively increased to reduce the separation distance between the rotary cutter 5 and the ground. .

Therefore, the lawn mower support device according to an embodiment of the present invention can adjust the coupling state and the coupling position of the connection unit 300 and the fixed unit 100 by a simple operation of the second QL lever module 310 without a separate tool. Since it can be easily changed, it is possible to freely change the height of the support unit 400 in accordance with the working environment, it is possible to variously adjust the separation height of the rotary cutter (5) from the ground.

In the above description, as shown in FIG. 5, the coupling hole 333 is formed in the connection plate 332, so that the second QR lever module 310 is coupled to the connection case 330 in which the connection plate 332 is formed. However, as shown in FIG. 6, only the second QR lever module 310 may be configured to be independently maintained in a loosely coupled state. At this time, it is preferable that the opening plate 336 is formed in the connection plate 332 so that the second QR lever module 310 in a loosely coupled state can be easily fastened without a separating operation.

On the other hand, the lawn mower support device according to an embodiment of the present invention may be configured to adjust the height of the support unit 400 according to the change in the coupling position of the support unit 400 and the connection unit 300 as described above. , It may be simply configured by inserting the support unit 400 between the coupling block 320 of a specific position to be in close contact with the coupling block 320 by the second Q Lever module 310, wherein The coupling position of the connection unit 300 and the fixed unit 100 may be maintained in a fixed state.

That is, as shown in FIGS. 7 and 8, the first fixing plate 110 of the fixing unit 100 protrudes so that two coupling plates 150 are arranged in a line up and down, and the coupling block 320 is formed in the two fixing plates 110. The coupling unit 300 is inserted between the coupling plate 150, and in this state, the connection unit 300 is fixed to the fixing unit 100 in such a manner that the coupling block 320 and the coupling plate 150 are tightly coupled by the second QR lever module 310. ) Is fixed to the vertical position. At this time, the support unit 400 is inserted between the coupling block 320 is coupled to the connection unit 300 in a manner that is closely coupled to the coupling block 320 by the second QR lever module 310, the coupling block The height of the support unit 400 is configured to be adjusted according to the insertion position of the support unit 400 relative to the 320.

In more detail, a plurality of coupling blocks 320 are inserted between two coupling plates 150 and coupling plates 150 are disposed at positions corresponding to coupling holes 321 of the coupling blocks 320. 153 is formed, the second rod bolt 311 passes through the fastening hole 153 and the coupling hole 321, the second fixing block 313 and the second fixing on the upper and lower ends of the second rod bolt 311 The coupling plate 150 and the second QR lever module 310 are coupled in such a manner that the nut 312 is coupled. In this case, the second fixing block 313 is disposed to contact the upper surface of the upper coupling plate 150 and the second fixing nut 312 is disposed to contact the lower surface of the lower coupling plate 150. Therefore, when the second actuating lever 314 rotates, the second fixing block 313 and the second fixing nut 312 press the two coupling plates 150 in the up and down direction, and thus the coupling plate 150. Coupling block 320 is disposed between is pressed and tightly coupled to each other. At this time, when the support unit 400 is interposed between the coupling block 320, the fixing unit 100 and the coupling block 320 is in close contact defect and at the same time the support unit 400 and the coupling block 320 is tightly coupled. .

As such, the support unit 400 may be coupled by being directly inserted between the coupling blocks 320, but according to another embodiment of the present invention, the support unit 400 is illustrated in FIGS. 7 and 8. It may be configured to be coupled to the coupling block 320 through a separate connection case 330 ′. To this end, the connection unit 300 further includes a hollow pipe-shaped connection case 330 'having an accommodating space therein so that the support unit 400 is inserted and coupled, and at least one side of the connection unit 330' is at least one side thereof. A cutout portion 331 'that is open in some sections is horizontally formed, and connecting plates 332' which are inserted between the coupling blocks 320 and pressurized in the up and down direction are respectively extended on the upper and lower sides of the cutout 331 '. Is formed.

Therefore, when the second actuating lever 314 is rotated to operate the second QL lever module 310 to closely engage the coupling block 320, the connection plate 332 ′ inserted into the coupling block 320 is inserted into the coupling block 320. It is pressed in the vertical direction by the coupling block 320 and tightly coupled with the coupling block 320. In addition, when the connecting plate 332 'is pressed up and down, at the same time, the connection case 330' is pressed up and down by the structural cutout 331 ', and thus the support unit inserted into the connection case 330' ( 400 is tightly coupled with the connection case 330 'in the connection case 330'.

According to this structure, when the second QR lever module 310 is operated to closely couple the coupling block 320, the fixing unit 100 and the support unit 400 together with the coupling block 320 are closely coupled at the same time. At this time, the height of the support unit 400 is adjusted according to the insertion position of the coupling block 320 of the connection plate 332 '. The height adjustment state of the support unit 400 is shown in FIG. 10. When the connection plate 332 ′ is inserted into the uppermost layer of the coupling block 320 as shown in FIG. 10A, the connection case ( The height of the support unit 400 coupled to 330 'is relatively increased to reduce the separation distance between the rotary cutter 5 and the ground, and as shown in FIG. 10 (b), the connecting plate 332' ) Is inserted into the lowermost layer of the coupling block 320, the height of the support unit 400 coupled to the connection case 330 'is relatively lowered to increase the separation distance between the rotary cutter 5 and the ground.

On the other hand, the connection plate 332 'is preferably formed with an open slot 335 along the insertion direction to be easily inserted between the coupling block 320 in the state coupled to the coupling plate 150. In addition, the embossing protrusion 152 is formed in the coupling plate 150 as described above, and insertion holes 322 and 334 corresponding to the coupling block 320 and the connection plate 332 'are formed to connect the connection plate 332. It is preferred to be configured to fix the position of ') and provide a feeling of operation to the user. Other detailed structures and operating principles are the same as those described with reference to FIGS. 5 and 6 and thus will be omitted.

As described above, the second QR lever module 310 may be configured to maintain a coupling state with the coupling plate 150, but as shown in FIG. 8, only the second QR lever module 310 is independently loose. It may also be configured to remain engaged. At this time, it is preferable that the opening plate 154 is formed in the coupling plate 150 so that the second QR lever module 310 in a loosely coupled state can be easily fastened without a separation operation.

Next, the configuration of the support unit 400 inserted into and coupled to the connection unit 300 described above and supported on the ground will be described in detail.

As described above, the distance Y may be relatively narrow by moving the first and second guide plates 410 and 420 linearly toward the center.

In addition, as shown in FIG. 12A, by changing the direction of the connection case 330 inserted into the coupling block 320, the first and second support guides 430 and 440 move forward and backward of the rotary cutter 5. It may be arranged to be located on both sides. This may be particularly useful if the direction of progress of the mowing operation has to proceed from left to right around the operator. That is, the mowing operation is carried out by swinging the rotary cutter 5 as necessary during mowing, in which case the first and second support guides 430 and 440 are arranged to be located at both front and rear sides of the rotary cutter 5. It would be advantageous to do that. In addition, as shown in FIG. 12B, if necessary, the first and second support guides 430 and 440 may be arranged to be located behind the rotary cutter 5, but not shown. As a result, the first and second support guides 430 and 440 may be disposed only on the left side or the right side of the rotary cutter 5.

The first and second link plates 470 and 480 may be coupled to the guide slot G by the QR lever module Q. This is to more stably fix the positions of the first and second support plates 450 and 460 through the QR lever module Q. However, the first and second link plates 470 and 480 are tightly coupled to the coupling block 320 by the second QR lever module 310 so that the first and second link plates 470 and 480 do not rotate. Since the gap between the support plates 450 and 460 is fixed, the first and second support plates 450 and 460 may be fixed at a specific position even without the QR lever module Q.
