Detailed Description of the Invention

[0001]

[Object of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tea leaf plucking machine, and a novel tea leaf capable of maintaining the straightness of the tea leaf plucking machine especially when moving along the tea ridge for plucking. The present invention relates to a method for towing a storage bag in a plucking machine.

[0002]

BACKGROUND OF THE INVENTION Although labor saving of tea leaf plucking work has been done in large-scale tea fields and tea fields under favorable conditions, it is not always sufficient in small-scale tea fields. However, labor saving is desired even in such small-scale tea farms due to the aging of the tea workers and the shortage of manpower. From such a request, the applicant of the present invention has, for example, driven by a prime mover such as an internal combustion engine or an electric motor in place of a portable plucking machine for two people, which is conventionally used by two workers holding a plucking machine in their hands. We have proposed a self-propelled device with running wheels (Japanese Patent Application No. 4-148422 "Tea garden management trolley"). However, in the case of plucking tea leaves with such a device, the labor was reduced, but in reality, two people were forced to work, and it was not possible to work alone. That is, in this case, a storage bag is attached to the rear of the plucking machine unit for plucking, the plucked tea leaves are stored therein, and the work is performed while the storage bag moves together with the plucking machine so as to shift on the tea ridge. However, as shown in FIG. 13, tension is applied to the plucking machine frame 40 in the direction of the ridges 6 due to the sliding resistance between the storage bag and the tea ridge that occurs at the center of gravity G of the carriage unit 2 as shown in FIG. And the moment works. In such a state, the moment of the plucking machine frame 40 near the truck unit 2 is absorbed by the friction between the traveling drive wheel 20 and the ground, but the moment far from the truck unit 2 acts significantly. As a result, the entire device tends to be biased toward the tea ridge 5. For this reason, this cannot be corrected by one worker on the traveling drive wheel 20 side, and an auxiliary handle H shown by an imaginary line is further attached to the plucking machine frame 40, and the operator is also positioned on the opposite side of the traveling drive wheel 20 to make the tea leaves. The correction operation was performed to keep the straightness of the plucking machine. For this reason, the development of a method that realizes labor saving of auxiliary work and finally enables operation by one person remains an issue.

[0003]

[Technical matter for attempting divisional application] In consideration of such a background, the applicant of the present invention, in the original application (Japanese Patent Application No. Hei 5-235350, "Structure for pulling bag in tea leaf plucking machine"),
In the tea leaf plucking work, the load on the tea leaf plucking machine is concentrated and guided to the rear of the orbit of the traveling drive body by the bag containing the tea leaves, and the traveling is made to have a high straightness, especially in the self-propelled plucking machine. Proposed a storage bag towing structure in a tea leaf plucking machine that can be operated by one person, and also discloses a method for pulling a storage bag in a tea leaf plucking machine in the original application, because the method itself is extremely effective, Regarding this "method of towing a storage bag in a tea-plucking machine", the original application is divided into a divisional application, and an attempt is made to acquire the right separately.

[0004]

[Constitution of the invention]

[Means for Achieving the Object] That is, the first invention of the method for towing the storage bag in the tea leaf plucking machine of the present application is to mow the tea leaf with the cutting blade of the plucking machine unit mounted on the traveling body that travels on a single rail, and cut the tea leaf. In the method of transferring by air flow and storing it in the rear tea leaf storage bag, when attaching the plucked tea leaf storage bag to the rear of the plucking machine unit, make sure that the traction resistance is concentrated almost behind the traveling body. It is characterized by what has been done.

In addition to the above requirements, the second invention of the method for towing a storage bag in a tea leaf plucking machine according to the present application is to attach the tea leaf pouch to a relay subframe and to pick up the frame surface of the relay subframe from the plucking machine unit. It is characterized in that it is set so as to be biased toward the traveling body with respect to the discharge port, and a relay transfer bag is provided between the relay subframe and the discharge port.

Furthermore, in the third invention of the method for towing a storage bag in a tea leaf plucking machine of the present application, in addition to the above requirements, the relay sub-frame set to be biased toward the running body is located near the running body. Rotate with the pin as a fulcrum,
This is characterized in that the load of the bag for storing tea leaves is concentrated on the pulling hooks which are provided a little closer to the furrow than this fulcrum, thereby causing slack in the relay transfer bag. The above objects are intended to be achieved by these inventions.

[0007]

According to the present invention, in the tea leaf plucking operation, the load applied to the tea leaf plucking machine is concentrated behind the track of the traveling drive body by the bag containing the tea leaves, and the truck unit is moved in the tea ridge direction. Since the moment of does not work, the straightness of the entire device is maintained as a result.

[0008]

EXAMPLE A tea leaf plucking machine according to the present invention will be specifically described below with reference to the illustrated embodiment. Reference numeral 1 is a tea leaf plucking device in which the present invention is implemented. As an example, the tea leaf plucking device is formed by combining a cart unit 2 with a plucking machine unit 3 that substantially plucks.

First, the carriage unit 2 will be described. In the illustrated embodiment, reference numeral 10 is a frame of the truck unit 2, which is constructed by combining square pipes made of steel or light alloy, for example. The frame 10 in this embodiment includes a main post 1 that is provided substantially vertically.

Further, a plucking machine support bracket 14 is provided near the lower part of the main post 11 so that the mounting position can be adjusted in the vertical direction so as to be fitted onto the main post 11. It is attached.

Specifically, the plucking machine support bracket 14 is provided with a support stay 14a which extends substantially horizontally so as to extend in the direction opposite to the handle bracket 13, and stands up substantially along the main post 11 above and is horizontal at the upper part. An almost L-shaped hanging stay 14 that overhangs
b, and further provided with a clamp bolt 14c, and by projecting the working end of the clamp bolt 14c,
The fixed state with the main post 11 can be maintained.

On the other hand, the generator support bracket 15 is provided so as to be slidably inserted into the main post 11. This is one in which a mount portion 15b is provided so as to horizontally project from the upper end of a square pipe-shaped slide portion 15a that fits in the main post 11. Clamp bolt 15c attached to
By being screwed in, the fixed state with the main post 11 is maintained.

An elevating shift cylinder C ₁ using a motor cylinder, for example, is interposed between the plucking machine support bracket 14 and the generator support bracket 15. That is, the main body side of the lift shift cylinder C ₁ is connected to the lower surface of the mount portion 15b of the generator support bracket 15, and the slider side end of the lift shift cylinder C ₁ is connected to the plucking machine support bracket 14. . By doing so, for example, the plucking machine support bracket 14
Alternatively, when one of the generator support brackets 15 is fixed to the main post 11 by tightening the clamp bolts 14c and 15c of the generator support bracket 15, the lifting shift cylinder C ₁ is contracted to the other non-fixed member. Try to move up and down. By this elevating operation, the set height of the plucking machine unit 3 is substantially adjusted.

The following members are further assembled to the frame 10 including such various brackets. First, reference numeral 20 is a traveling drive wheel, and as an example, a wheel using a pneumatic tire is provided at the tip of the traveling body support arm 12 below the frame. This drive wheel 20
As shown in FIG. 6, a drive motor M is mounted in the vicinity of the chain, and a chain 21 is suspended between the output sprocket S ₁ and the driven sprocket S ₂ of the traveling drive wheel 20 to transmit the rotation. A clutch mechanism 22 for connecting and disconnecting the drive motor M and the traveling drive wheel 20 is provided. In this structure, the driven sprocket S ₂ is always free to rotate with respect to the axle of the traveling drive wheel 20, while the clutch disc 22a rotating together with the axle of the traveling drive wheel 20 is in the axial direction. Is slidable on the clutch disc 22
An engaging structure is provided between a and the driven sprocket S ₂ , so that the clutch is disengaged when the clutch disc 22a is separated from the driven sprocket S ₂ against the clutch spring 22b.

The operation is performed by the clutch shifter 23. The shift fork 23a of the clutch shifter 23 shifts the clutch disc 22a and the other end of the clutch shifter 23 is provided with a release lever 23b. The clutch disk 22a is separated from the driven sprocket S ₂ by being pulled by the clutch wire 23c which is moved by receiving a lever operation or the like provided on the handle.

The above-mentioned traveling drive wheel 20 is an example of a traveling body, and the traveling body is not limited to such a tire type, but an appropriate type such as a crawler type can be applied. Further, in the present specification, the description that the traveling body (including both driven and non-driven) is provided on a single rail means that a traveling body that travels substantially through one ridge is provided. This means that the traveling drive wheel 20 is provided as a single rail even if the traveling drive wheel 20 is set in a state of being in contact with, for example, a double tire or having a certain width. Further, as will be described later, it goes without saying that it is easier to perform the management work in the tea field when the left and right of the machine body are balanced, and in this embodiment, the auxiliary wheels described later as shown in FIG. 2 driving drive wheels for 25
0 is 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 displaced. Of course, this tread position may be in the matched state.

On the other hand, an auxiliary wheel 25 is provided at the 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. Specifically, as an example, a bell crank-shaped link bracket 26 is attached to the traveling body support arm 12 at one end thereof. It is rotatably attached to the pivot shaft 27 on the part side, and the lower end of the link bracket 26 is pulled to the traveling drive wheel 20 side by the suspension spring 28 in a state of being pulled, whereby the fork with the upper end of the link bracket as a fulcrum. The wheels supported by 29 are configured to be movable in the vertical direction. Further, the auxiliary wheel 25 is set in a range in which the caster shaft 29A of the fork 29 can be rotated to some extent, which enables natural straight traveling.

Further, as an example, a bifurcated handle 30 is attached from a handle bracket 13 provided near the middle of the main post 11 so that its attachment angle can be adjusted by a serration 31. The mounting position of the handle 30 itself may be set to an appropriate fixed position by configuring the entire handle bracket 13 so as to be movable up and down along the main post 11.

Next, the generator support bracket 15 has a generator 33 for supplying power to the drive motor M of the traveling drive wheel 20.
Equipped with. And, as already mentioned for this generator support bracket 15, the lifting shift cylinder C
The set position can be adjusted by activating ₁ . That is, in order to adjust the mounting position (height) of the generator 33, the plucking machine support bracket 14 is attached to the clamp bolt 14c.
After being fixed by tightening, the elevating shift cylinder C ₁ is contracted. In this case, the generator support bracket 15 is moved up and down according to the contraction of the up-and-down shift cylinder C ₁ , and is set at an appropriate position. It should be noted that the plucking machine unit 3 mounted on each bogie unit 2 including the generator 33 and the members constituting the tea leaf plucking device 1 are substantially balanced with the tread direction of the traveling drive wheels 20 as the center of gravity. It is preferable to take such a layout. Further, in consideration of stability during traveling, it is preferable that the generator 33 is provided at such a high position, and the mounting position is set low, for example, by using the cover 24 of the traveling drive wheel 20 and mounting it above the cover 24. .

Next, together with the mounting structure of the plucking machine unit 3,
The setting position adjusting mechanism 50 of the plucking machine unit 3 will be described. First, the plucking machine unit 3 is rotatably supported by the support stay 14a near the engine-side end of the plucking machine frame 40. A connection bracket 51 is provided near the center of the upper part of the plucking machine frame 40. The connection bracket 51 is included in the set position between the connection bracket 51 and the hanging stay 14b protruding from the upper side of the main post 11. An adjusting mechanism 50 is provided.

The space formed inside such an arcuate portion of the extension arm 54a is defined as a relief portion 56, and the relief portion 5 is formed.
By providing 6, the suspension stay 14b and the extension arm 54a
That is, the rotation range of the expansion arm 54a is increased by avoiding the interference with the.

On the other hand, the connecting rod 55 serves to transmit the movement of the slider 53 of the tilt shift cylinder C _{2 to} the expansion arm 54a, and one end of the linking rod 55 together with the slider 53 of the tilt shift cylinder C ₂ is provided. The connection bracket 51 is rotatably supported at a predetermined connection position, and the other end is also rotatably supported near the tip of a linearly extended portion of the extension arm 54a.

[0023] The extension further proximal end of the inclined shift cylinder C ₂ is the arm 54a is be one that is rotatably supported by the pivot shaft 57, thereby tilting the shift cylinder C ₂ is extended arm 54a It is configured to reciprocate while swinging with the rotation of.

And such a tilt shift cylinder C ₂

From this, according to the basic configuration, the cutting blade 42 is provided in the ridge width direction according to a conventional method, and the cutting blade 42 is driven by the prime mover 41 to which an internal combustion engine or an electric motor is applied. Then, around the cutting blade 42, the relay transfer bag 48, the relay sub-frame 47, the storage bag 43, and the plucked tea leaves A, which are the characteristic configurations of this device, are sent to the storage bag 43 via the relay transfer bag 48. And a guide plate 42A and a slide plate 42B are provided behind the cutting blade 42.

First, the blower unit 44 will be described in more detail. As shown in FIG. 10, reference numeral 44A indicates the prime mover 41.
A blower unit incorporated on the output shaft side of the blower unit, and a blower duct 44B including a part of its casing is extended from the blower unit 44A so as to extend along the cutting blade 42 in a substantially diagonally upper front direction. It Then, a plurality of blow-out pipes 44E are branched below the blow-out pipes 44E, and the tips thereof are used as blow-out holes 44F. Specifically, the blower unit 44
The airflow F is led out from a part of the casing of A, and the direction of action 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 at the rear. It is set in the blowing direction.

Next, various devices for harvesting the plucked tea leaves A are provided behind the blowing device 44.
Specifically, the above-mentioned relay sub-frame 47, the relay transfer bag 48, and the storage bag 43, which are the characteristic configurations of the present invention, are provided, which will be described below.

As shown in FIG. 4, the relay sub-frame 47 is a frame-shaped member that is connected to the plucking machine frame 40 via a bearing bracket 46 and rotates horizontally with this as a fulcrum. The mounting structure of the relay sub-frame to the plucking machine frame 40 has a bearing bracket 46 and a pin 47a.
And the 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 is a U-shaped member provided so that the bearing portion that locks the pin 47a faces the upper and lower portions of the shaft holding portion 46a of the bearing bracket 46. Bearing bracket 46
Is fixed to the plucking machine frame 40 by tightening bolts in the bolt holes 46c. On the other hand, the shaft fitting portion 47b is fixed to the relay subframe 47. Then, 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 horizontally rotated about this as a fulcrum. Further, the relay sub-frame 47 is provided with the engaging hooks 40A for mounting the relay transfer bag 48 and the accommodation bag 43 at several positions in the vertical and width directions of the relay sub-frame 47. Here, the characteristic configuration of the relay sub-frame 47 is that a towing hook 40B serving as a power point is provided on the furrow 6 side of the pin 47a, and most of the load of the accommodation bag 43 is applied here.

The relay transfer bag 48 is the cut tea leaves A.
The passage entrance 48A of the cutting blade 42 is largely opened so as to extend over almost the entire width of the cutting blade 42, and the engaging hooks 40A of the relay transfer bag 48 are attached to the picking machine frame 40 at several positions in the vertical and width directions in order to mount the same. Set up. Then, the passage inlet 48A and the passage outlet 48B in the relay transfer bag 48
Is configured through a rubber band 43C or the like so that it can be locked to the hook. Further, the characteristic configuration of the relay transfer bag 48 is as shown in FIG.
The 7a side is shorter than the free end side of the relay subframe 47.

The storage bag 43 has a large opening 43A on the receiving side of the cut tea leaves A so as to cover substantially the entire width of the relay sub-frame 47. Attach to the tow hook 40B. Then, the receiving side opening 43A of the accommodation bag 43 is configured through a rubber band 43C or the like so that it can be locked to the hook.

The tea leaf plucking apparatus for carrying out the bag plucking method in the tea leaf plucking machine according to the present invention has a specific structure as described above, and mainly the treatment mode of the tea leaf A which is the body to be cut will be described below. The operation mode is described in the above, and the method of the present invention is substantially explained. In this work, the plucking machine unit 3 is adjusted to a predetermined position with respect to the tea ridges 5 in height and angle according to a conventional method, and the bogie unit 2 is moved to the ridges 6 while driving the prime mover 41. Three
The cutting blade 42 is driven to cut the tea leaves A. At this time, the blower unit 44A driven by the prime mover 41
Supplies the air flow F to the blower duct 44B, and these are blown out to the rear of the guide plate 42A from the blowout hole 44F. The tea leaf A is blown off by the air flow F into the relay transfer bag 48 located behind the guide plate 42A, and finally stored in the storage bag 43.

Further, in order to ensure the treatment of the cut tea 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
The upper end of 8A is hooked on the plucking machine frame 40 or the locking hook 40A of the slide plate 42B, and the lower part is inserted below the guide plate 42A (that is, between the guide plate 42A and the slide plate 42B). Attach so that it interrupts. Further, the receiving opening 43A of the accommodation 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 off from the guide plate 42A pass through the relay transfer bag 48 and enter the storage bag 43, and the end 43B thereof is deflected toward the furrow 6 side. You will be guided to the 6th side.

The tea leaf plucking 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, so that the traction resistance increases as the accommodating amount of the tea leaves A increases. . Then, as shown in FIG. 13, tension is applied to the plucking machine frame 40 in the ridge 6 directions, and a moment about the center of gravity G acts on the carriage unit 2.
The moment of the plucking machine frame 40 near the bogie unit 2 is absorbed by friction between the traveling drive wheels 20 and the ground, but the moment far from the bogie unit 2 acts remarkably, resulting in a device. Whole tea ridge 5
It tends to be biased to the side, and the straight line, which is a regular track, is not maintained and tries to enter the tea ridge 5. By the way, conventionally, an auxiliary handle H shown by an imaginary line is further attached to the plucking machine frame 40, and an operator is also arranged in the furrow 6 on the other side of the tea ridge 5, so that it is a two-person work, and the assistant worker corrects the trajectory. The work mode is as follows. This auxiliary worker also has a role of suppressing the shaking (particularly the vertical direction) of the plucking machine unit 3 due to the irregularly shifting the storage bag 43 in the state of storing the heavy tea leaves A on the tea plant. I was carrying it.

However, in the present invention, since the frame surface of the relay sub-frame 47 is rotated so as to be deflected toward the traveling drive wheel 20 with respect to the discharge port of the tea leaf plucking device 1, the accommodating bag attached to the relay sub-frame 47. The ridge 6 side of 43 is strongly pulled, and strong tension is not applied to the tea ridge 5 side of the accommodation bag 43. Further, in the present invention, the pin 47a, which serves as a fulcrum of the relay sub-frame 47, is on the traveling axis of the traveling drive wheel 20,
When the pulling resistance of the bag 43 for storing the tea leaves A is concentrated on the pulling hook 40B provided slightly closer to the ridge 6 than the fulcrum pin 47a, the relay sub-frame 47 is rotated toward the plucking machine unit 3 side. The slack is caused in the relay transfer bag 48. Therefore, the tea leaf plucking device 1 maintains a regular straight path with respect to the tea ridges 5 without generating a moment with respect to the plucking machine unit 3. Further, since the tea leaves A stored in the storage bag 43 are concentrated near the furrow 6, the plucking due to the fact that the storage bag 43 in the state where the heavy tea leaves A are stored shifts irregularly on the tea plant. The shaking of the machine unit 3 (especially in the vertical direction) can be eliminated, and stable plucking can be performed. Further, the traction resistance is concentrated only on the traveling axis of the traveling drive wheels 20, and the force for pressing the carriage unit 2 against the ground is increased, so that the driving force by the traveling drive wheels 20 is increased and the stability of traveling is enhanced.

[0035]

Other Embodiments The present invention uses the method shown in the above-mentioned embodiment as a typical embodiment, but the following embodiments can also be adopted. First, as disclosed in claim 1, if the pulling resistance is configured to be applied substantially rearward of the traveling body, the moment generated with respect to the plucking machine frame 40 can be reduced, so the relay sub-frame 47 is not particularly provided. Using the type 1 tea leaf plucking device 1, the storage bag 4
As shown in FIG. 12 (a), a configuration in which the end 43B is sufficiently smaller than the receiving side opening 43A of the tea leaf A or the like and is displaced from the center of the receiving side opening 43A to one side as shown in FIG. Is also effective, and FIG.
It is also effective to form the receiving side opening 43A side obliquely with an appropriate angle as shown in FIG. Furthermore,
As disclosed in claim 2, even if the frame surface of the relay sub-frame 47 is fixed so as to be biased toward the traveling body with respect to the discharge port of this machine, the moment generated on the plucking machine frame 40 can be reduced. . Further, as shown in FIG. 1, a wire 45 for citation is attached to the accommodating bag 43, and this wire is connected to, for example, the cover 24 of the traveling drive wheel 20,
Even if the storage bag 43 is held in a slack state with respect to the plucking machine, the moment generated with respect to the plucking machine frame 40 can be reduced.

Although the above-described embodiment is applied to the one-sided mowing type self-propelled plucking machine, the storage bag 43 is used.
The same effect can be obtained by applying it to a double-sided mowing or rail-running type plucking machine as long as it does not have a mechanism for mounting the above and drags on the tea plant or the furrow 6. 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 trolley that travels on the rail is pushed by hand. The type is easier to handle.

[0037]

Since the present invention has the above-mentioned structure, the following effects can be obtained. First, in the plucking operation of the tea leaves A, the load applied to the tea plucking machine is concentrated and guided to a certain position by the storage bag 43 that contains the tea leaves A, and the traveling of the tea leaves is made highly straight, so that it can be operated by one person. Become. Further, since the tea leaves A stored in the storage bag 43 are concentrated near the furrow 6, the plucking due to the fact that the storage bag 43 in the state where the heavy tea leaves A are stored shifts irregularly on the tea plant. The shaking of the machine unit 3 (especially in the vertical direction) can be eliminated, and stable plucking can be performed. Further, the traction resistance is concentrated only on the traveling axis of the traveling drive wheels 20, and the force for pressing the carriage unit 2 against the ground is increased, so that the driving force by the traveling drive wheels 20 is increased and the stability of traveling is enhanced.
