That is, the posture of the support arm 26 is set by the extended state of the extendable telescopic shift actuator 27 attached so as to connect between the upper extension 16a of the sub-traveling body frame 16 and the tip side of the support arm 26. In addition, the installation height of the sub-running body 16 can be changed. The shift actuator 27 uses a so-called electric cylinder as an example, and is supplied with power from the engine generator 18 to be expanded and contracted. Of course, the specific specifications of the shift actuator 27 are not limited as long as the members can achieve such an object. For example, a hydraulic cylinder, a spiral shaft, or other appropriate linkage mechanism can be applied.

Further, along the traveling direction of the drive traveling body 20, an auxiliary wheel 30 is provided on the rear side of the drive traveling body 20 mainly for assisting the straight traveling action. That is, the auxiliary wheel 30 is a caster-shaped wheel, and is attached to the tip of the auxiliary wheel frame 17 via the caster fork 31. The caster fork 31 is constructed so as to be able to swivel appropriately on the rotation support portion 32 on the upper part thereof, and by further providing a clamp bolt 33 on the upper part of the caster fork 31, it is fixed to the auxiliary wheel frame 17 side fixing member.

Further, as an example, the cylinder responding portion 48 extended in the direction opposite to the branching work direction is extended, and the suspension actuator 49 is disposed between the cylinder receiving portion 47 and the cylinder responding portion 48. With the expansion and contraction of the suspension actuator 49, the trimmer unit 3 selects the posture in the suspension state. Incidentally, the lifting actuator 43 and the suspension actuator 49 both apply a motor cylinder that operates by receiving power from the engine generator 18, but this also performs the same operation as the shift actuator 27 described above. Can be changed to.

Next, the trimmer unit 3 mounted on the elevating bracket 40 will be further described. This has the same basic structure as a trimming trimmer already commercially available as a portable type and has a simple mechanism. For example, a prime mover 50 using, for example, a two-cycle engine or the like.
And a blower 51 for blowing and collecting the branches and leaves in a certain direction.
Below that, a transmission unit 52 for cutting blades is further provided. Along the cutting blade frame 53 extending from the transmission unit 52, one or both sets of so-called hair clipper type cutting blades 54 are provided by the eccentric drive mechanism provided in the transmission unit 52. The rotation of the prime mover 50 is driven by the power converted into reciprocating motion. A guide plate 55 is provided behind the cutting blade 54.

Of course, in addition to such members, a shatterproof plate is provided in order to prevent excessive blowout of the branched branches, and a bag for collecting the branches or leaves in the rear of the guide plate 55 or for guiding in a certain direction. Alternatively, a guide member in the shape of a streamer may be attached. Further, the cutting blade 54 of the trimmer unit 3 is linear in this embodiment, but may be arcuate or the like depending on the shape of the planting to be trimmed. Also, in the basic embodiment shown in FIGS.
Although only one trimmer unit 3 is provided, a trimmer unit for vertical branching may be additionally provided for the trimmer unit 3 as shown in FIG. At this time, if space is allowed, one trimmer post 12 may be provided with two trimmer units 3. If space is not allowed, trimmer posts 12 may be provided as shown in FIG. Alternatively, one trimmer unit 3 may be attached to the one planted.

The drive-running trimmer 1 according to the present invention has a specific structure as described above and operates as follows. (1) Work Preparation First, when performing work, the engine generator 18 is started to supply power to various functional members. As a result, it becomes possible to drive the lift actuator 43 or the suspension actuator 49 for setting the posture, trimming position, etc. of the trimmer unit 3 by receiving power from the engine generator 18, and further, setting the posture of the auxiliary traveling body 25. It is possible to drive the shift actuator 27 for driving, and it is also possible to drive the traveling body drive motor M for traveling the driving traveling body 20. Also, of course, the trimmer unit 3 itself activates the prime mover 50, which is the driving force for direct branching action.

(2) Setting according to the traveling place The setting according to the traveling place means that when the drive traveling trimmer 1 travels along the planting 5, the curb 6 of the planting 5 is used, for example, in a park, a street or the like. When an inclination for collecting water is provided nearby, this is a work to be performed for always setting the preferable posture of the drive traveling trimmer 1. Specifically, since the installation surface opposite to the planting 5 is often high as shown in FIG. 4, first, the installation height of the sub-traveling body 25 in the carriage unit 2 is set to the driving traveling body 20. Set to be higher than That is, the shift actuator 27 is actuated in the contracting direction, and the support arm 26 thereof is pulled up and driven. As a result, the sub-traveling body 25 is displaced to a higher position, so that the drive-driving trimmer 1 as a whole inclines if the sub-traveling body 25 side is lowered if it is flat. However, as described above, since the traveling road surface itself is higher on the side opposite to the trimming work side as shown in FIG. 4, under such circumstances, for example, the trimmer post 1
Seen in 2, this is set in a substantially vertical state.

(3) Setting of trimmer unit In such a situation, the cutting blade 54 of the trimmer unit 3 is aligned with the planting 5 to be next trimmed. In many cases of such planting 5, the upper surface is first leveled horizontally, so the position of the trimmer unit 3 is set accordingly. The trimmer unit 3 itself sets the position of the movable bracket 12a that receives the lifting actuator 43 below, for example, to the lowermost position, and if there is a height to be adjusted within the extension stroke of the lifting actuator 43, the movable bracket 12a is movable. 1
In 2a, the elevating actuator 43 is simply moved up and down in that position to align it with the branching surface of the planting 5. Further, when the branching surface of the planting 5 is higher than that, the movable bracket 12a is moved upward and fixed to the trimmer post 12, and then the elevating actuator 43 is contracted to be set at an appropriate position. By doing so, the elevating actuator 43 itself does not necessarily have to have a stroke that covers the upper limit to the lower limit of the adjustable position, but within the limit that the elevating bracket 40 fits into the trimmer post 12, an appropriate adjusting action is achieved. Height can be set.

(4) Branching Work In this branching work, the drive traveling body 20 first receives the power from the traveling body drive motor M and travels. After such preparation work or various posture setting works are completed, the branching work is performed. The trimming work is to drive the drive-running trimmer 1 along the planting 5, and the clutch mechanism 22 is operated to obtain the driven state. In this traveling, for example, when the curb 6 is provided, the pair of front and rear guide wheels 35 travel while contacting the side edge portions of the curb 6 to perform a certain guiding action also in this portion, for example. Progress is made according to plant 5. Of course, when such work is performed in a straight line, the straightness of the guide wheel 35 can be improved by setting the guide wheel 35 in a straight line state.
Of course, when the planting 5 is formed in a curved shape, the guide wheel 35 is used as a caster wheel that can move freely, and the drive traveling type trimmer 1 is appropriately operated by operating the handle.
May be run.

When such running is performed, for example, the cutting blade 54 of the trimmer unit 3 arranged substantially horizontally branches the upper surface of the planting 5 substantially smoothly. When the trees 7 are mixedly planted in the planting 5 in such a state, in order to avoid this, the cutting blade 54 in the trimmer unit 3 should be sufficiently moved upward as shown by a phantom line in FIG. To avoid this. That is, this work drives the suspension actuator 49 in the direction of extension. As a result, the suspension actuator 49 has its upper end fixed by the cylinder receiving portion 47, and thus acts to push down the cylinder responding portion 48 that is substantially integrated with the trimmer unit 3. When doing so, the trimmer unit 3 is configured to lift the cutting blade 54 upward with the rotation support portion 46 as the center. After such avoidance is completed, the suspension actuator 49 is contracted again to return to the original horizontal state, which is almost the working state, and the work is continued.

(5) Forwarding When such a branching operation is completed and is forwarded to an appropriate position, the clutch mechanism 22 is disengaged so that the drive traveling body 20 can be freely rotated. And forward.

(6) Other forms of branching Although the above-described branching work is basically performed, two trimmer units 3 as shown in FIG. 4 are provided, one for horizontal branching and one for vertical branching. Even in such a case, when the drive-running trimmer 1 is made to travel along the planting 5 to be trimmed, those cutting blades 54 trim the upper surface and the side surface of the planting 5. Further, although only one trimmer unit 3 is provided, in the case of a configuration in which the cutting blade 54 can be set in the vertical direction so that the horizontal trimming and the vertical trimming can be performed by only one trimmer unit 3, , For example, after trimming the upper surface of the planting 5 substantially horizontally, the trimmer unit 3 is entirely cut with the cutting blade 54.
Arrangement is performed in the vertical direction, and then the branching work is performed. In the case of the basic embodiment already described, this operation can be performed by setting the cutting blade 54 to the vertical state, for example, depending on the extension state of the suspension actuator 49. In this case, the trimmer unit is used. In consideration of the fact that the branched branches and leaves fall on the drive unit such as the prime mover 50 in FIG. 3, when only one trimmer unit 3 is applied for horizontal and vertical branching, the vertical plane branching is performed. When performing the above, it is preferable to use another rotation mechanism to set the vertical branching work posture so that the prime mover 50 side is directed upward and the cutting blade 54 hangs downward.

[0037]

The present invention has the structure as described above, and has the following effects. First, claim 1
According to the invention described above, since the trimmer unit 3 performs the branching work of the planting 5 while the carriage unit 2 is traveling, the operator therefore handles the operation handle after the trimmer unit 3 is aligned with the branching surface. It is possible to continue the work with a light labor that supports 19 and manages only the operation of the switches of the operation system.

According to the second aspect of the present invention, by switching the installation height of the auxiliary traveling body 25 for regulation adjustment, the entire drive traveling trimmer 1 can be tilted, which allows the branching surface Regardless of the setting, etc., regardless of the inclination of the traveling position of the carriage unit 2, it is possible to always set a preferable branching posture.

Furthermore, according to the third aspect of the invention, since the auxiliary wheel 30 for setting the traveling direction is provided, the traveling direction of the carriage unit 2 can be always guided in a fixed direction, and the work can be performed. It is possible to reduce the traveling operation of the person.

Further, according to the invention described in claim 4, the trolley unit 2 has one or more guide wheels 35 on the working side, which is provided near the root of the planting 5 during working. Since the curbstone 6, which often occurs, comes into contact with the curbstone 6 from the side and guides the curbstone 6, more accurate traveling is achieved.

Furthermore, according to the fifth aspect of the invention, the trimmer unit 3 can set the branching work position so that it can be moved up and down with respect to the carriage unit 2, so that it can be easily aligned with the branching surface of the planting 5.

Further, according to the invention of claim 6, since the trimmer unit 3 is attached to the elevating bracket 40 so as to be freely laid, for example, a tree 7 or the like exists in the planting 5. When performing the branching work while avoiding the above, the trees 7 and the like can be avoided by raising the trimmer unit 3 to the upper end side.

Furthermore, according to the invention as defined in claim 7, since the trimmer unit 3 is provided with two units for horizontal and vertical trimming, the upper and side surfaces of the planting 5 are trimmed at once. be able to.
