[0001]

[Object of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tea leaf picking machine, and more particularly to a novel tea leaf which can maintain the straightness of the tea leaf picking machine when moving along a tea ridge for picking. The present invention relates to a storage bag towing structure in a plucking machine.

[0002]

BACKGROUND OF THE INVENTION Although labor saving in the operation of picking tea leaves has been carried out in large-scale tea gardens and tea gardens under favorable conditions, it is not always sufficient in small-scale tea gardens. However, recently, due to the aging of workers and the shortage of workers of tea farmers, labor saving is desired even in such small-scale tea gardens. From such a demand, the present applicant has been driven by a prime mover such as an internal combustion engine or an electric motor instead of a conventional two-person portable plucking machine in which two workers work with a plucking machine in hand. (Japanese Patent Application No. 4-148422, "Tea garden management trolley"). However, when tea leaves are plucked by such a device, although labor is reduced, in practice, two people have to work, and one person cannot work. That is, in this case, the storage bag is attached to the rear of the plucking machine unit for plucking, the picked tea leaves are stored therein, and the work is performed while moving the storage bag together with the plucking machine so as to be shifted on the tea ridge. However, due to the sliding resistance between the storage bag and the tea ridge generated at this time, tension is applied to the plucking machine frame 40 in the six ridges as shown in FIG. Work moment. In such a state, the moment on the plucking machine frame 40 near the bogie unit 2 is absorbed by friction between the traveling drive wheel 20 and the ground, but the moment far from the bogie unit 2 acts significantly. As a result, the entire apparatus tends to be biased toward the tea ridge 5 side. For this reason, this cannot be corrected by one worker on the traveling drive wheel 20 side, and an auxiliary handle H indicated by a virtual line is further attached to the plucking machine frame 40, and the worker is positioned on the opposite side to the traveling drive wheel 20 to make tea leaves. Correction operation was performed to maintain the straightness of the plucking machine. For this reason, labor saving of the auxiliary work has been realized, and finally, the development of a device capable of being operated by one person remains as an issue.

[0003]

[Technical Issues Attempted to Be Developed] The present invention has been made in view of such a background. In a tea leaf picking operation, a load applied to a tea leaf picking machine is reduced by a storage bag containing the tea leaves behind the orbit of the traveling driving body.

You. A plurality of outlet pipes 44E are branched below the outlet pipes, and the ends of the outlet pipes 44E serve as outlet holes 44F. Specifically, the blower unit 44
The air flow F is led out from a part of the casing of A. The operating direction of the blowout hole 44F is such that the tea leaves A cut by the cutting blade 42 are guided in the direction of the intermediate transfer bag 48 provided rearward. It is set in the blowing direction.

Next, various devices for harvesting the picked tea leaves A are provided behind such a blowing device 44.
More specifically, the relay sub-frame 47, the relay transfer bag 48, and the storage bag 43, which are characteristic features of the present invention, are provided. This will be described below.

As shown in FIGS. 3 and 4, the relay sub-frame 47 has a substantially vertical frame surface and runs in a plan view.
Close to the plucking machine unit 3 on the side of the body (drive wheels 20)
In contact with and separated from the plucking machine unit 3 at the other end
It is arranged so that it is. And this relay subframe 4
7 on the side of the traveling body (traveling drive wheel 20).
6 and is connected to the plucking machine frame 40, and is configured so as to rotate in a horizontal direction with the connection point as a fulcrum . The mounting structure of the relay sub-frame to the plucking machine frame 40 includes a bearing bracket 46, a pin 47a, and a shaft fitting portion 47b as main members. The bearing bracket 46 includes a shaft holding portion 46a and a mounting portion 46b, and the mounting portion 46b has a bolt hole 46c. The shaft fitting portion 47b includes a pin 47a.
The bearing for locking the shaft is fixed to the shaft holder 46 of the bearing bracket 46.
This is a U-shaped member provided so as to face the upper part and the lower part of a. The bearing bracket 46 is fixed to the plucking machine frame 40 by tightening a bolt into the bolt hole 46c. On the other hand, the shaft fitting portion 47b is fixed to the relay sub-frame 47. By locking the shaft fitting portion 47b and the shaft holding portion 46a with the pin 47b, the relay sub-frame 47 is connected to the plucking machine frame 40, and can be freely rotated in the horizontal direction about this point as a fulcrum. Further, the relay sub-frame 47 is provided with several locking hooks 40A in the vertical and horizontal directions of the relay sub-frame 47 for mounting the relay transfer bag 48 and the storage bag 43. Here, a characteristic configuration of the relay sub-frame 47 is that a towing hook 40B serving as an emphasis point is provided closer to the ridge 6 than the pin 47a, and the load of most of the storage bag 43 is applied thereto.

The relay transfer bag 48 is made of the cut leaves A
The opening 48A of the intermediate transfer opening 48A is largely opened so as to cover almost the entire width of the cutting blade 42. In order to mount this, the locking hooks 40A of the relay transfer bag 48 are mounted at several positions in the vertical and width directions of the plucking machine frame 40. Provide. Then, the passage entrance 48A and the passage exit 48B in the relay transfer bag 48
Is configured to pass through a rubber band 43C or the like so as to be locked to the hook. Further, as shown in FIG. 3, the characteristic configuration of the relay transfer bag 48
The 7a side is shorter than the free end side of the relay sub-frame 47.

The storage bag 43 has a receiving side opening 43A for the cut leaves A, which is widened so as to cover almost the entire width of the relay sub-frame 47. Attach it to the towing hook 40B. 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.

The device of the structure for pulling the storage bag in the tea picking machine according to the present invention has the specific structure as described above. explain. In this operation, the height and angle of the plucking machine unit 3 are adjusted to a predetermined position with respect to the tea ridge 5 in accordance with a conventional method, and the bogie unit 2 is caused to run in the ridge 6 while the motor 41 is driven. The cutting blade 42 of No. 3 is driven to cut the tea leaves A. At this time, the blower unit 4 driven by the prime mover 41
4 supplies the air flow F to the air blow duct 44B, and these are blown out from the outlet 44F to the rear of the guide plate 42A.
Tea leaves A is blown off the relay transfer bag 48 located behind the guide plate 42A by the air flow F, the relay transfer bag 48
Is finally stored in the storage bag 43.

Further, in order to ensure the processing of the cut leaves A, the relay transfer bag 48 and the storage bag 43 are used as follows. That is, the passage entrance 4 of the relay transfer bag 48
8A is hooked on the catch hook 40A of the plucking machine frame 40 or the slide plate 42B on the upper end side, and is inserted below the guide plate 42A below (that is, between the guide plate 42A and the slide plate 42B). Attach it). Further, the receiving opening 43A of the storage bag 43 is hooked and attached to the locking hook 40A and the towing hook 40B of the relay sub-frame 47. In this case, the tea leaves A blown from the guide plate 42A pass through the relay transfer bag 48 and enter the storage bag 43, and the terminal end 43B is deflected to the ridge 6 side. You will be guided to the 6 side.

The tea leaf picking device 1 cuts the tea leaves A by the cutting blade 42 and advances the furrow 6 while accommodating the tea leaves A in the accommodating bag 43. . As shown in FIG. 13, tension is applied to the plucking machine frame 40 in the six ridges, and a moment about the center of gravity G acts on the bogie unit 2.
The moment of the plucking machine frame 40 near the bogie unit 2 is absorbed by friction between the traveling drive wheel 20 and the ground, but the moment far from the bogie unit 2 acts remarkably, and as a result, the device The whole is tea ridge 5
It tends to be deviated to the side, and attempts to enter the tea ridge 5 without keeping the straight orbit, which is the regular trajectory. By the way, conventionally, an auxiliary handle H indicated by an imaginary line is further attached to the plucking machine frame 40, and the workers are also arranged in the ridge 6 on the other side of the tea ridge 5, so that it is a two-person operation, and the auxiliary worker corrects the trajectory. The work mode of doing was adopted. This auxiliary worker also has a function of suppressing the swinging (particularly in the vertical direction) of the plucking unit 3 due to the irregular displacement of the storage bag 43 containing the heavy tea leaves A on the tea tree. I was carrying it.

However, in the present invention, the relay subframe
Frame 47 is set so as to be deflected toward the traveling drive wheel 20.
Therefore, the relay subframe 47 is
The ridge 6 side of the storage bag 43 attached to the storage bag 43 is strongly pulled, and strong tension is not applied to the tea ridge 5 side of the storage bag 43.
Further, according to the present invention, the pin 47a serving as the fulcrum of the relay subframe 47 is located above the traveling axis of the traveling drive wheel 20, and the tea leaf is provided with respect to the towing hook 40B provided slightly closer to the ridge 6 than the pin 47a serving as the fulcrum. When the traction resistance of the storage bag 43 of A is concentrated, the relay sub-frame 47 rotates toward the plucking machine unit 3 and causes the relay transfer bag 48 to slack. For this reason, the tea leaf pruning apparatus 1 maintains the normal straight trajectory with respect to the tea ridge 5 without generating a moment with respect to the plucking machine unit 3. Also, since the tea leaves A stored in the storage bag 43 concentrate near the furrow 6, the pruning caused by the conventional storage bag 43 in which the heavy tea leaves A are stored is shifted irregularly on the tea tree. The shaking (particularly in the vertical direction) of the machine unit 3 can be eliminated, and stable plucking can be performed. Further, since the traction resistance is concentrated only on the traveling axis of the traveling drive wheel 20 and the force for pressing the bogie unit 2 against the ground increases, the driving force by the traveling drive wheel 20 increases,
Driving stability is improved.

[0037]

Other Embodiments The present invention is based on the embodiment described above as a representative embodiment, but other modifications are possible.
First, as described in claim 1, the traction resistance of the storage bag 3 is determined by the traveling body (the traveling drive wheel 20) in the bogie unit 2.
Even configured to concentrate backwards on the axis of travel
Lever, it is possible to reduce the moment caused by relative plucking machine frame 40, in particular using a relay subframe 47 device 1 adopting the type of tea Hatsumi without the, figure storage bag 43 1
As shown in FIG. 2 (a), the terminal end 43B is configured to be sufficiently smaller than the receiving side opening 43A of the cut leaves A and the like and shifted to one side from the center of the receiving side opening 43A. Also, as shown in FIG. 12 (b), it is also effective to form the receiving opening 43A side at an appropriate angle. Further, claim 2
As described above, the moment generated on the plucking machine frame 40 can be reduced even if the frame surface of the relay sub-frame 47 is fixed so as to be deflected toward the traveling body with respect to the discharge port of the machine. That is, the relay sub-frame 47 is
And the traveling body (traveling drive) in plan view.

From the plucking machine unit 3 to the relay subframe 47
It is also possible for the part to be constituted by an integral member. FIG.
As shown in FIG.
Mounting, this thing is connected to, for example, cover 24 of the travel driving wheel 20 or the like, bag 43 reduces the moment generated by relative plucking machine frame 40 also to be held in a loose state with respect plucking machine it can.

In the above-described embodiment, the present invention is applied to the single-sided cutting type self-propelled tea leaf picking apparatus 1. However, the mechanism for placing the storage bag 43 is not provided and the tea tree or the furrow 6 is not provided. A similar effect can be obtained by applying the present invention to a double-sided mowing or rail-running type plucking machine as long as it is a type of dragging. For example, when adopting a rail-running plucking device as an applicable model, the straightness is stable as in the previous example, so that an effect of preventing derailment can be obtained, and in particular, a bogie traveling on a rail is manually pushed. Type is easier to handle.

[0039]

Since the present invention has the above-described configuration, the following effects can be obtained. First, in the plucking operations of tea leaves A, the bag 43 containing the tea leaves A
The load applied to the tea leaf picking device 1 is concentrated and guided to a certain position, and the traveling is made straight forward, so that the operation can be performed by one person. Also, since the tea leaves A stored in the storage bag 43 concentrate near the furrow 6, the pruning caused by the conventional storage bag 43 in which the heavy tea leaves A are stored is shifted irregularly on the tea tree. The shaking (particularly in the vertical direction) of the machine unit 3 can be eliminated, and stable plucking can be performed. Further, since the traction resistance is concentrated only on the traveling axis of the traveling drive wheel 20 and the force for pressing the bogie unit 2 against the ground increases, the driving force by the traveling drive wheel 20 increases, and the stability of traveling increases.
