Branching, shallow cutting, deep cutting,
It is also called middle cutting or dairy cutting. In most of these operations, the cut pieces of the tree are left in the tea ridges, so that the conventional pruning machines for this type of work use airflow to move the tree pieces in a predetermined direction. There is provided a member for blowing off. Specifically, in the case of a portable two-person pruning machine, an air flow is generated by a blower unit having a prime mover that drives a cutting blade as a drive source, and tree fragments cut by the cutting blade by the air flow are generated. He was trying to blow it off to the end opposite to the prime mover.

[0003] When labor saving is required for this kind of pruning work, there is a tendency to carry out the pruning work by mounting a pruning machine unit from a portable type to a rail traveling vehicle or a furrow traveling vehicle. In such a case, the processing of the pruned tree pieces is slightly different from the case of the portable type, and further suitable processing is required. For example, in the case of a self-propelled type in which the engine side of the pruning machine unit is mounted on a bogie unit that travels on the ridge with a single rail, the engine side of the pruning machine unit is located in the ridge. , The other end is positioned substantially at the upper end of the center of the tea ridge, and the tree is cut and thrown toward the furrow (motor side). However, when such a method is employed, on the ridge side (the side where tree fragments are thrown away), in addition to the prime mover in the pruning machine unit, there are various functional members such as a drive unit of a traveling trolley, and the mowing was directly cut off. It is also anticipated that dropping dendrites will hinder the smooth operation of these functional members.

Further, in this specification, the description that the traveling body is provided on a single rail means that the traveling body that travels substantially between one tea furrow is provided, and the traveling drive wheel 20 is provided. For example, even if it is set in a state of being in contact with a double tire or having a certain width, it is still a single rail.
As will be described later, it is needless to say that it is easier to perform the management work in the tea garden when the body is balanced in the left and right direction on the operation surface, and in this embodiment, as shown in FIG. In contrast to 25, the traveling drive wheels 20 are in a state of being unevenly distributed on the side of the tea ridge 5 where some work is performed. In other words, the tread positions of the wheels are set to be shifted. Needless to say, the tread positions may be matched.

On the other hand, an auxiliary wheel 25 is provided at an end of the traveling body support arm 12 facing the traveling drive wheel 20. This is attached to the frame 10 so as to be movable in a certain range in the vertical direction and the traveling direction.

Note that the members constituting the tea plant management device 1 with the management unit 3 mounted on each bogie unit 2 including the generator 33 are generally balanced with the tread direction of the traveling drive wheel 20 substantially at the center of gravity. It is preferable to take such a layout. In consideration of stability during running, it is also preferable to set the generator 33 at such a high position, and to set the mounting position low, for example, by using the cover 24 of the driving wheel 20 and mounting it above the driving wheel 20. .

Next, together with the mounting structure of the management unit 3,
The setting position adjusting mechanism 50 of the management unit 3 will be described. First, in the pruning machine which is an example of the management machine unit 3, the vicinity of the engine side end of the pruning machine frame 40 is rotatably supported by a support stay 14a. A connection bracket 51 is provided in the vicinity of the upper center of the pruning machine frame 40. The connection bracket 51 is provided between the connection bracket 51 and the suspension stay 14b projecting from the upper side of the main post 11 including the connection bracket 51. A position adjustment mechanism 50 is provided.

The setting position adjusting mechanism 50 includes a shifter 52 serving as a rotation drive source of the management unit 3, an extension / enlargement portion 54 for extending the working length of a slider 53 of the shifter 52, and the pruning machine frame. And a connection bracket 51 provided on the shift shifter C. The shifter 52 includes, as an example, a tilt shift cylinder C composed of a motor cylinder.

A connection position adjusting mechanism 58 is provided at the connection portion. In the present embodiment shown in FIGS. 1 to 5, a plurality of portions for rotatably supporting the slider 53 and the connecting rod 55 are provided, and these are selected when the slider 53 and the connecting rod 55 are attached. By doing so, the adjustment range of the inclination angle of the management machine unit 3 is further expanded.

The management unit 3 applied here
The pruning machine as an example has the same basic configuration as that of a portable pruning machine, and has a form in which the operation handle of a portable pruning machine for two persons is removed. From this, the basic configuration is such that the cutting blade 42 is provided in the ridge width direction according to a conventional method, and is driven by the prime mover 41 to which an internal combustion engine or an electric motor is applied. A blower 44 is provided around the cutting blade 42 for sending the pruned tree fragments A to the storage bag 43, which is a characteristic configuration of the present apparatus. A guide plate 42A and a slide plate are provided behind the cutting blade 42. 42B is provided.

The blower unit 44 will be described in more detail. Reference numeral 44A denotes a blower unit incorporated on the output shaft side of the prime mover 41.
Blast duct 44B including a part of the casing from 4A
Is a cutting blade 42 substantially obliquely upward and forward as an example of a cutting blade.
It is formed so as to extend along. Further, a distal end duct 44C to which a flexible tube is applied as an example is further connected to the distal end side. The tip duct 44C is fixed to the pruning machine frame 40 at the opposite end of the prime mover 41, that is, at the top of the tea ridge, and opens a main blowout hole 44D as a first blowout hole . Thus the main blowout hole 44D in this embodiment has an air flow F ₁ is set in the direction as supplied toward the engine side in the opposite side of the prime mover 41. Of course, as defined in claims 1 to 3, depending on the pruning mode, the setting is not limited to such a direction, and for example, the air is blown from the prime mover 41 side toward the other end side. It does not matter if it takes any form. In short, air flows from the top of the tea ridge to the space between the tea ridges
The flow should just go. Hereinafter, when the air flows are collectively referred to as an air flow F.

The main outlet 44D is open at the tip of a distal end duct 44C to which a flexible tube is applied, but the application of the flexible tube to the distal end duct 44C is not limited. A resin pipe or a metal pipe having a certain rigidity may be applied. In addition, the air duct 44B and the end duct 44C may be integrally formed, and a method such as using the inside of the frame member of the pruning machine frame 40 as a duct may be adopted. The point is that a piping structure in which an air flow is supplied from a predetermined position in a predetermined direction may be adopted.

Further, as an example, three sub-blowout pipes 44E are branched downward from the blower duct 44B at a portion which also serves as a part of the casing of the blower unit 44A, and the distal end thereof is connected to a sub-blower serving as a second blowout hole. The outlet hole 44F is used. Specifically is obtained by so derive air flow F ₂ from a portion of the casing of the blower unit 44A, the direction of action of the auxiliary outlet holes 44F in the supply leading end side of the air flow F ₁ of the main outlet hole 44D, It is set in the blowing direction to guide it backward.

Further, an auxiliary outlet pipe 44G is branched between the blow duct 44B and the end duct 44C, and the end thereof is an auxiliary outlet 44H as a third outlet . This is, as an example, a ventilation duct 44B and a tip duct 44C.
Are attached to a joint piece 441 provided therebetween, and the orientation thereof can be changed and adjusted. The blowing direction of the air flow F _3, in addition to the obliquely rearward as shown, the air flow F ₁ of the main blowout hole 44D
It may be oriented in the same direction as above, or may be at the rear perpendicular to this. In addition, such a structure in which the blowing direction can be adjusted may be applied to one or some of the main blowing holes 44D and the sub-blowing holes 44F, or all of them.

Further, the above-mentioned storage bag 43 is provided at the rear of such a blowing device 44 in order to further reliably guide the cut tree pieces A. This will be described below. The storage bag 43 has a receiving side opening 43A of the cut tree piece A which is largely opened so as to cover almost the entire width of the cutting blade 42. In order to mount the storage bag 43, the locking hook 40A of the storage bag 43 is required. Are provided at several locations in the vertical and horizontal directions of the pruning machine frame 40. The receiving side opening 43A of the storage bag 43 is formed through a rubber band 43C or the like so that the receiving side opening 43A can be engaged with the hook. Further, as shown in FIG. 7, a characteristic configuration of the storage bag 43 is a receiving opening 43 such as a tree piece A whose end 43B is cut off.
A is smaller than A, and is shifted to one side from the center of the receiving side opening 43A.

The terminal end 43B is opened when the tree piece A can be thrown into the furrow 6 in the case of a pruning operation or the like. Of course, when it is desired to recover the end, the end 43B may be closed. When the storage bag 43 moves so as to be displaced on the tea ridge 5, the movement resistance pulls the pruning machine, which is an example of the management device unit 3, backward, and the management device unit 3 moves the frame 1.
In order to avoid this, a tow wire 45 is attached to the storage bag 43, and this is attached to, for example, the cover 2 of the traveling drive wheel 20.
4 and the like, and the storage bag 43 may be held in a slack state with respect to the pruning machine.

The tea plant management apparatus according to the present invention has a specific structure as described above. Hereinafter, the operation mode and the tea plant management method will be described focusing on the processing mode of the cut tree piece A. In this operation, the pruning machine, which is the management machine unit 3, is adjusted to a predetermined position with respect to the tea ridge 5 by adjusting the height, angle, and the like, and the bogie unit is moved between the tea ridges 5 while driving the prime mover 41. The cutting machine 42 is driven to drive the cutting blade 42 of the pruning machine, which is the management machine unit 3, to cut the tea tree. At this time, the blower unit 44 driven by the prime mover 41 supplies the airflow F from the blower duct 44B to the distal end duct 44C, and these are blown in predetermined directions from the main blowout hole 44D and the sub blowout hole 44F, and further from the auxiliary blowout hole 44H. It will be blown out.

Firstly the primary air flow F ₁ from blowout hole 44D is furrow 6 side from the top side of the tea ridges 5 substantially along the guide plate 42A
The tree pieces A cut by the cutting blade 42 are moved on the guide plate toward the prime mover 41 side. In the vicinity of the prime mover 41, the airflow F flowing rearward from the sub-blowing holes 44F.
Kiedahen A that have been collected by ₂ are made to be blown to the rear of guide plate 42A, the position being blown is a furrow 6 tea ridges 5, the various functional components of 且 one truck unit 2 They are blown off behind. Of course, in order to help this tendency,
Balloon air flow F ₃ towards some obliquely rearward from H is also more effective.

Of course, by observing the cutting situation, the main outlet 44
D, any one of the sub-blowing holes 44F, the auxiliary blowing holes 44H, etc., or some or all of them, can be adjusted to set a preferred throwing position of the tree fragments A. Further, in order to ensure the processing of the cut tree pieces A, it is a preferable working mode to use the storage bag 43. That is, the receiving opening 43A of the storage bag 43 is
The upper end side is a locking hook 4 in the pruning machine frame 40.
0A, and the lower part is the guide plate 42A.
(That is, guide plate 42A).
And the slide plate 42B). In this case, the tree pieces A blown off from the guide plate 42A enter the storage bag 43, and the terminal end 43B is deflected to the ridge 6 side, so that it is guided to the ridge 6 side. When the terminal end 43B is open, it is sequentially discharged to the furrow 6.

In all the embodiments described above,
The tea plant management device 1 can be operated by a worker alone, but an auxiliary handle 46 is further attached to the pruning machine frame 40 as shown in FIGS. If workers are arranged on the side, it is possible to perform two people.

[0040]

Since the present invention has the above-described structure, the processing direction (throwing direction) of the tree piece A cut by the pruning operation can be set in a more preferable direction. In particular, in the case of the management machine unit 3 combined with the self-propelled management cart, the tree pieces A are not thrown onto the related functional members such as the traveling cart, and a smooth operation can be expected.
