A plucking machine can also be applied.

Next, the plucking machine body 3 will be described. As shown in FIG. 1 and FIG. 2 as an example, the plucking machine body 3 has two plucking machine frame pipes 31 arranged in parallel above and along the arc of the upper surface of the tea ridge T below the plucking machine frame pipes 31. The plucking machine frame substrate 32 is provided substantially in parallel, and the plucking machine engine 33 is mounted at a position closer to one side of the plucking machine frame pipe 31. The plucking machine engine 33 drives a cutting blade 34 to which a clipper blade is applied as an example, and the plucking machine frame substrate 32 receives air blown from a fan integrally assembled below the plucking machine engine 33.
A blower duct 35 for blowing upward is arranged diagonally above and above the cutting blade 34. The cutting blade 34 is provided substantially on the front side of the plucking machine frame substrate 32. The part of the plucking machine body 3 which is partitioned by the plucking machine frame pipe 31 and the plucking machine frame substrate 32 and from which the plucked tea leaves A are lifted and transferred by the relay transfer device 5 is referred to as a plucking action part 36.

Next, the accommodating portion 4 will be described. Storage part 4
Is a part for finally storing the plucked tea leaf A and holding the stored leaf bag 6b. The accommodating portion 4 is, for example, as shown in FIGS. 1 to 4, a relay transfer device 5 described later.
A plurality of leaf-collecting bags 6 provided in a basket-like shape below the discharge part 53 of
And a holding frame 41 for holding the
And a rotary shaft 42 fixed to 1.
The holding frame 41 includes, as an example, circular stays 43 arranged above and below the rotation shaft 42, connecting stays 44 that connect the two circular stays 43 in a substantially vertical direction, and the circular stay 43 and the rotation shaft. Connecting stay 4 for connecting 42 with the radial direction
5 and a partition stay 46 provided so as to partition the plurality of leaf-collecting bags 6. The partition stay 46 is formed by connecting the upper and lower circular stays 43 so as to incline so as to have an appropriate angle. The rotary shaft 42 is rotatably supported on the rear portion of the traveling machine body 2, and a belt wheel 47 is provided at the tip end portion as an example. The belt wheel 47 is rotated by a separately provided motor or the like to rotate the holding frame 41. Incidentally, in this embodiment, the housing portion 4
The six leaf-collecting bags 6 are attached to the above, but this can be appropriately changed according to various environments such as the size of the tea garden to be plucked.

Next, the relay transfer device 5 will be described. The relay transfer device 5, together with the plucking machine 3, is supported by a slider 25 so as to be able to move up and down, and the plucked tea leaves A are accommodated in the accommodating portion 4.
The blow-up fan 51 and the blower duct 5 as shown in FIGS. 1 to 4 as an example.
2 and a discharge part 53 that causes the tea leaves A to drop substantially toward the storage part 4. As one example, the blow-up fans 51 are provided on the upper side of the traveling machine body 2 on the left and right sides, and are driven by a separately attached motor or the like to blow air into the blower duct 52.

The blower duct 52 blows the plucked tea leaves A from the rear part of the cutting blade 34, which is the plucking action part 36, to the accommodating part 4. Specifically, the wind blown from the blowing fan 51 is the tea leaves. It reaches the plucking action part 36 by wrapping around the side part of the plucking machine 1, and joins the tea leaves A at this part,
After the merging, the tea leaves A are blown to the storage section 4 via the tea leaf transfer path 52a. In addition, this confluence is used for tea leaves A
Is defined as the ascending transfer starting portion 36a. Also the air duct 5
2, the side part is doubled as an example, and is set to be expandable / contractible as the plucking machine body 3 moves up and down. Therefore, the blowing fan 51 is always fixed to the traveling machine body 2 regardless of whether the plucking machine body 3 is raised or lowered. To be done.

The tea leaf transfer path 52a is provided with an ascending transfer start portion 36.
The tea leaves A are moved up from the a to the discharge part 53, and the cross-sectional shape in the transfer path is smoothly changed as the tea leaves A are transferred. Specifically, as shown in FIGS. 1 and 4, the tea leaf plucking machine 1 is viewed in the front-rear direction so that a worker who is driving can secure a sufficient rear view, and the curved shape is detoured to bypass the center of the rear. Take. The inside space in which the tea leaf transfer path 52a is curved is defined as a detour section 52b, and two left and right detour sections 52b constitute an open space that substantially secures a rear view, and the detour section 52b transfers the tea leaves. It serves to avoid contact between the passage 52a and the housing portion 4.

Further, in this embodiment, as an example of a structure for smoothly changing the cross-sectional shape in the transfer path, FIG.
As shown in (a), the ascending transfer starting portion 36a to the discharging portion 5
3 is gradually changed over almost the entire area up to 3, but may be changed in a portion near the ascending / transferring start portion 36a as shown in FIG. 6B. Therefore, the "smoothness" described in claim 1 includes the case where the cross-sectional shape is changed in almost the entire area of the tea leaf transfer passage 52a or in an appropriate portion. Note that in any of the above-described forms, the cross-sectional area S in the transfer path is set so as not to damage the tea leaves A (when displayed separately, from the side closer to the ascending transfer start portion 36a, S1, S2, S
3, S4 ...) are preferably maintained constant. Of course, the cross-sectional area S at each portion may be changed within the range where the object of the present invention can be achieved.

On the other hand, the plucked tea leaf A is moved upward in the transfer path formed as described above while maintaining the transfer direction component behind the cutting blade 34 as it is, so that it may be damaged during the transfer. There is no. Further, the tea transfer path 52a
The inner surface is plated or tritetrafluoroethylene (trade name Teflon: registered trademark of DuPont) to prevent sticking of tea leaves A during transfer or to reduce transfer resistance.
Has been subjected to processing such as coating. It is also possible to provide an auxiliary fan above or below the slope of the transfer path.

The discharge portion 53 is located at the upper end portion of the tea leaf transfer path 52a, and is a portion that causes the tea leaf A, which has been lifted and transferred, to almost naturally drop toward the leaf storage bag 6, as an example shown in FIG.
As shown in, the plucking machine is formed in a state of being smoothly bent from the side part to the central part. Therefore, in this bent portion, there is a concern that the transfer direction component maintained from the rear of the cutting blade 34 to the tea leaf transfer path 52a is forcibly bent to damage the tea leaves A, but in reality, the action of the transfer wind is It gradually decreases as the inner pressure rises, and the transfer effect is practically negligible in the portion reaching the discharge portion 53. Therefore, even if the discharge part 53 is formed in a bent state, the tea leaves A are not damaged in this part. A guide member such as a chute or a guide sheet for guiding the fall of the tea leaves A can be provided around the discharge portion 53. Further, in this embodiment, the transfer form in which the tea leaves A are blown up by the blowing fan 51 to transfer the tea leaves A to the accommodating portion 4, but a transfer form in which the tea leaves A are lifted by a conveyor or the like may be adopted.

Next, the tea leaf plucking machine 1 configured as described above
The tea leaf accommodating structure of the present invention will be substantially described while explaining the operation mode of. (1) Mounting of uncontained leaf collecting bags First, as an example, six uncontained leaf collecting bags 6a are attached to the circular stay 43 above the housing 4 in a suspended state prior to the substantial plucking work. At that time, the leaf bag 6 is attached by an appropriate attachment means such as a cord or a clip.
Then, for example, the slider 25
Various settings such as the height setting of the plucking machine body 3 and the relay transfer device 5 and the lowest point setting of the cutting blade 34 by the winch 26 are performed.

(2) Tea Plucking When the above-mentioned mounting work is completed, the operator sits on the operator seat 27 and starts the engine unit 24, and the control unit 23 drives the crawler 22 and the plucking machine engine 33. , The plucking of tea leaf A is started.
At that time, the tea leaves A are blown into the air duct 3 as shown in FIG.
5 is sent to the rear of the plucking action part 36 by the air discharged from the blower 5, and then blown up through the blower duct 52
The air blown out from No. 1 moves upward in the tea leaf transfer path 52a. It should be noted that if the tea leaves A can be sent to the discharge portion 53 which is the upper end portion of the tea leaf transfer path 52a by the air discharged from the air blowing duct 35, it is of course possible not to blow the air from the blowing fan 51. .

Here, the tea leaf transfer path 52a is configured such that the cross-sectional shape in the transfer path is changed smoothly along with the transfer of the tea leaves A. As shown in FIGS. In order to secure a sufficient field of view, the tea leaf plucking machine 1 is viewed in the front-rear direction and has a curved shape so as to bypass the rear central range. Therefore, the plucked tea leaves A are moved upward in the transfer path while maintaining the transfer direction component behind the cutting blade 34 as shown in FIG. 5A, and are not damaged during the transfer. Further, by adopting such a structure, the contact of the tea leaf transfer path 52a with the container 4 is also avoided.

After that, the tea leaves A reach the discharge part 53 formed so as to bend toward the central part of the plucking machine, but in this discharge part 53, the effect of the transfer air is almost lost and this part is lost. However, there is no damage, and
As shown in (b), it is accommodated in the leaf-collecting bag 6 while being almost naturally dropped from the discharge part 53. When the tea leaf bag 6 located below the discharge portion 53 is almost filled with the tea leaves A, the container portion 4 is rotated by an appropriate angle, and the next leaf bag 6 is discharged to the discharge portion 5.
It is located below 3. Further, since the leaf-collecting bag 6 is attached in a suspended state, a large number of tea leaves A are stored in one leaf-collecting bag 6.

(3) Removal of stored leaf bag All the leaf bags 6 attached to the containing portion 4 are tea leaves A.
When it is almost full, the plucking operation is interrupted and the stored leaf bag 6b is removed. At that time, first, the attachment of the leaf-collecting bag 6 is released, the open end side is closed with a string or a sheet fastener, and the stored leaf-closing bag 6b is placed at an appropriate place. After that, the uncollected leaf bag 6a is again stored in the storage section 4 for the next plucking operation.
Attach in a circular shape to the suspended state. It should be noted that such replacement work of the leaf-collecting bag 6 is intermittently repeated during the plucking work.

[0025]

According to the tea leaf accommodating structure of the tea ridge crossing type tea leaf plucking machine according to the first aspect, a large amount of tea leaves A can be obtained at once.
Since the rear view of the plucking machine can be sufficiently secured while storing the tea leaves without damaging the
It is possible to easily confirm the accommodation state of the operator even from the operator seat 27. Further, even when an operator goes to the accommodation section 4 to fix the accommodation, the relay transfer device 5 does not interfere, and of course, it is necessary to always arrange the operator for confirming the accommodation status in the accommodation section 4. Absent.

According to the tea leaf accommodating structure of the tea ridge crossing type tea leaf plucking machine according to claim 2, when the plucked tea leaf A is accommodated in the leaf-collecting bag 6, the tea leaf A is not damaged and is more reliable. The tea leaves A can be stored in.

Furthermore, according to the tea leaf accommodating structure of the tea ridge crossing type tea leaf plucking machine according to the third aspect, since the plurality of leaf accommodating bags 6 are collectively attached in a circular shape, it is easier to confirm the accommodating shape. The rear view can be secured more reliably.

According to the tea leaf accommodating structure of the tea ridge crossing type tea leaf plucking machine according to the fourth aspect, the labor of the tea farm farmer can be reduced.
