Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a riding-type tea leaf picking machine for picking tea leaves while moving over tea ridges, and more particularly, to mount a container for holding the picked tea leaves. Related to the configuration of the loading platform.

[0002]

2. Description of the Related Art In recent years, with the aging of workers, there is an urgent need to automate various machines for managing tea gardens and reduce the work load. In order to respond to these demands, for example, a rail track type tea leaf pruning machine and a riding type tea leaf pruning machine have been proposed. The rail track-type tea leaf picking machine is provided with a portal frame that is provided so as to straddle the tea ridge on a track truck that runs on a track rail laid along the ridge,
A plucking device is provided on the portal frame so as to be able to move up and down. And while running the truck, the plucking device was activated,
The plucked tea leaves are stored in a tea leaf storage bag provided behind the plucking device. Thus, the tea leaves can be appropriately plucked and stored with a relatively inexpensive device.

Further, the riding type tea leaf picking machine comprises a picking device, a large air blower, and a large housing device for housing tea leaves in a riding body which runs over a tea ridge and runs between ridges on both sides thereof. Provided. Then, the passenger body is put in the ridge, the plucking device is operated to perform the plucking operation, and the plucked tea leaves are pressure-fed by a blower, raised in a duct, and stored in the storage device. As a result, the picking operation can be performed with a riding-type picking machine as long as the picking operation is not performed on an extremely sloped place.

[0004]

The above-mentioned track-rail type and riding type tea picking machines both have advantages, but also have the following disadvantages. First, in the case of a track rail type tea leaf plucking machine, the equipment body is relatively inexpensive due to the simple equipment configuration, but the track rail must be laid all over the furrow, which costs much, and as a result, It will be expensive. Therefore, in small and medium-sized tea gardens with a small area where rails are laid, the benefits are fully exhibited, but in large-scale tea gardens, rail laying costs are high and there is a problem that this system cannot be introduced. . In addition, when the rails are laid, the rails may interfere with the management of the tea plantation such as the application of the fertilizer in the tilling operation, which may hinder the maintenance of the tea plantation.

[0005] In addition, in the case of a riding type tea leaf plucking machine, the equipment configuration itself is large and the price itself is expensive. In some tea gardens, there is a problem that this system cannot be introduced. In addition, when a riding-type tea leaf pruning machine is used, the ground may be compacted depending on the weight of the pruning machine, which may make it difficult to dig up during tilling work and may make it difficult to manage the tea plantation. There is.

[0006] Further, in the tea leaf plucking machine, it is desirable that the plucked tea leaves be accommodated in a container such as a tea bag and the plucking operation be continued while replacing the container with a new container when the container is filled with the tea leaves. However, if such replacement of the container is to be carried out in as small number of times as possible, a large storage device is required as described above. For this reason, it is undeniable that the structure of the plucking machine becomes large. When the structure of the plucking machine becomes large, a driving source required for driving the pruning machine needs to have a large output, which causes an increase in plucking cost. In addition, when the accommodation device is made large, the turning radius of the tea leaf picking machine becomes large, and it may be difficult to perform the turning operation in a narrow place.

SUMMARY OF THE INVENTION In view of the above-mentioned problems in the conventional tea leaf picking machine, the object of the present invention is to make use of the advantages of the track rail type and the riding type tea leaf picking machine, and to make the apparatus structure in a narrow place without increasing the size of the apparatus structure.

A plucking device having a blowing means, and a loading platform that is provided behind the plucking device and mounts a container that stores the tea leaves pumped by the plucking device,
And the loading platform is configured such that a part of the container in the full length direction is extended to the full length of the container and is at least shorter than the full length of the container. The position stored in the plucking device can be selected.

According to a second aspect of the present invention, in the simple riding type tea picking machine according to the first aspect, the loading platform is a guide portion located at a rear portion of the plucking device and a sub loading platform that can be disposed on an extension of the guide portion. The sub-carrier is configured to select a posture that extends rearward from the guide portion so as to form a mounting surface of the container together with the guide portion and a position that is stored on the lower surface of the guide portion. It is characterized in that it can be configured.

[0010]

According to the first and second aspects of the present invention, the carrier used for placing the container for accommodating the tea leaves is arranged so as to be protruded and shorter than the container for placing the container. You can select the posture stored on the plucking device side,
According to the second aspect of the present invention, the length of the plucking machine can be shortened as the retracted position by turning the auxiliary carrier positioned on the extension of the guide portion between the extended position and the retracted position.

Next, the working mode of the simple riding type plucking machine 1 configured as described above will be described. First, when the sub-carrier 5A is stored on the lower surface of the guide plate 49, the sub-carrier 5A is stored.
A is set to the overhanging position. In this case, the auxiliary carrier 5A extends along the second guide groove 70B of the sliding guide member 70.
Is pulled out, and the pin 71 provided on the side surface of the auxiliary carrier 5A is pushed into the locking groove via the vertical groove in the first guide groove of the sliding guide member 70, whereby the auxiliary carrier 5A can be extended. In this state, the locking portion of the swing support member 72 is fitted to the pin 5A2 provided on the side surface of the sub-loading carrier 5A, and the locking pin is engaged with a locking hole having one end of the swing support member 72 in the support plate 73. 74 is held.
A container (not shown) such as a tea bag is placed on the loading platform 5 including the sub-loading platform 5A thus protruded. The container is
The opening end is attached to the support frame 41 of the plucking device 4 and arranged. Then, the operator gets on the simplified riding plucking machine 1 and sits on the cockpit 25, operates the control unit 27, and puts the simplified riding tea plucking machine 1 in a tea garden across an appropriate tea ridge. Prior to entering the tea garden, an uncontained container is prepared in the receiving member 6.

Next, the control unit 27 is operated to raise and lower the motor 4.
Next, the picking device 4 is moved up and down to move the picking device 4 and the bed 5 up and down to determine the picking position. Then, the engines 44 and 45 are started to operate the picking device 4. Further, by operating an accelerator (not shown) for engine control provided in the control unit 27, supply of oil to the hydraulic motor 34 is started, and the traveling device 3 is caused to travel to perform a plucking operation. Here, the tea leaves plucked by the plucking device 4 are pushed backward by compressed air from a nozzle 46 a of a blower tube 46 provided in the plucking device 4 so as to be accommodated in a container provided on the bed 5. Become. Since the bed 5 is long, a large container can be mounted, and the plucking operation can be performed without replacing the container in a row of tea ridges.

When the picking operation proceeds and the container on the bed 5 is filled with the picked tea leaves, the operator replaces the container. In this case, two methods can be selected. In other words, a method of exchanging the container while the plucking device 4 is positioned at a position where the plucking device 4 can be plucked on the top surface of the tea tree ridge, This is a method of replacing the container. In either case, the lifting motor 48 as the lifting drive source of the lifting body 47 is only provided at the top of the lifting flange 23, so that the loading platform 5 is located behind the cockpit 26.
There is no member that is suspended in the width direction of the car body above
As shown by a two-dot chain line in FIG.
There is formed a space that can be moved directly from 6 to the carrier 5. For this reason, in the former method, although there is some level difference between the cockpit 26 and the carrier 5, in the latter method, the carrier 5 is moved to the cockpit unless the container hits the portal frame 22 and collapses. Since the step can be made smaller by approaching 26, the labor required for the operator to move can be reduced.

On the other hand, the container fully loaded on the loading platform 5 is mounted on the loading member 6 when the open end is removed on the loading platform 5, and the loading member 6 or the vehicle body 2 other than the loading member is used. A new container prepared at the location is attached to the plucking device 4 and the plucking operation is restarted. When the mounting amount of the container on the load receiving member 6 reaches the limit, the collecting operation of the container is performed. The collection operation is performed by the bracket 6A1 on the support member 25A (see FIG. 7) side of the bracket 6A1 that the worker has on the load receiving member 6 with the traveling device 3 stopped.
As shown in FIG. 1, the load receiving member 6 is tilted so that the bottom frame 6A is tilted at the angle indicated by the symbol φ, and the mounted container is dropped. . In this case, by pulling out the locking pin 6D, the load receiving member 6
The engagement between the bracket 6A1 and the vehicle body side is released. It is preferable to perform such a collection operation when moving from a tea plantation to a headland. Also, during the collection operation, the receiving member 6
Not only can the container fall naturally, but also can swing the movable side frame 6C (see FIG. 7) and drag it to the side of the vehicle body. The movable side frame 6C may be set at an angle at which the container can be mounted at the time of working in the tea garden. For example, the movable side frame 6C may go out on the road and move between the tea leads. As shown by P1, the swing position can be determined so as to be vertical or at an acute angle with respect to the bottom frame 6A so as not to widen.

On the other hand, if the turning space is small when the plucking machine turns, the auxiliary loading platform 5A of the loading platform 5 is stored on the lower surface of the guide plate 49. In this case, the locking pin 7 inserted into the locking hole of the support plate 73 at one end of the swing support member 72
Pull out 4 and swing the swing support member 72 downward,
The locking portion is detached from the pin 5A2 of the auxiliary carrier 5A. When the locked state of the sub-carrier 5A by the swing support member 72 is released, the sub-carrier 5A is
The first guide groove 70A is pulled out so as to be displaced from the locking groove in the first guide groove 70A to the position of the groove in the vertical direction (the state shown by a two-dot chain line in FIG. 6), and the state facing the second guide groove 70B. When the auxiliary carrier 5A is located on the lower surface of the guide plate 49, it is pushed into the lower surface of the guide plate 49 and stored in the lower surface of the guide plate 49. When the supplementary loading platform 5A is stored on the lower surface of the guide plate 49, the distance that the sub-loading platform 5A projects rearward is reduced, so that the turning radius can be reduced.

According to the present embodiment, the driving engine 60 of the traveling device 3 is arranged on the connecting frame 25 so that the exhaust gas generating source is positioned above the so-called tea tree ridge. Therefore, it is possible to prevent the exhaust air from directly contacting the tea plant, thereby suppressing the exhaust pollution of the tea leaves. Further, in this embodiment, by swinging the movable side frame 6C of the load receiving member 6, the number of members projecting to the side of the vehicle body 2 can be reduced. That is, the movable side frame 6C stands up or is folded to the bottom frame 6A side so that the movable side frame 6C is
Since it does not protrude outward, it can be prevented from interfering with the support for the anti-frost fan and hinder running. Further, the receiving member 6 including the bottom frame 6A is provided.
By removing itself, the above-mentioned overhang amount can be further reduced, and it becomes easy to avoid an obstacle located on the side of the plucking machine 1. In the above embodiment, the plucking device 4
Is configured to include the cutting blade 43 that can cover the entire width of the top surface of the tea tree ridge, but the length of the cutting blade 43 is not the entire width of the tea tree ridge but a half region. Of course, it is possible. Further, although the traveling device 3 has been described as a rubber crawler type, a caterpillar type may be used, and the plucking device 4 is not limited to the clipper blade type, but may be a cylinder type rotor blade.

In the above-described embodiment, the overloading position and the storage position can be selected by sliding the sub-package 5A. However, the present invention is not limited to this configuration. When detached, it may be mounted on the lower surface of the guide plate 49 and stored. Further, when the auxiliary carrier 5A is stored or extended, the operation is not limited to the manual operation as in the above-described embodiment, but may be performed using the electric drive source, the hydraulic drive source, or the air drive source connected to the auxiliary carrier 5A. Of course, it is also possible to automatically perform the operation by the operation from.

[0030]

As described above, claims 1 and 2
According to the described invention, the loading platform used to place the container that stores the tea leaves is stored on the plucking device side so as to be shorter than the container and the posture that protrudes to place the container. In particular, according to the second aspect of the present invention, the auxiliary carrier located on the extension of the guide portion can be selected between the extended position and the retracted position, so that the retracted position can be selected at the time of turning. As the position, the total length of the plucking machine can be shortened to reduce the turning radius, and the plucking operation can be performed in a state where the container can be mounted by setting the overhanging position. With this configuration, in the overhanging position where the container can be placed, the frequency of replacement work can be reduced by mounting a relatively large container to reduce labor, and when the turning radius is small, the container can be overhanging. By storing the sub-carrier, the length of the carrier can be shortened and the turning radius can be reduced, so that turning at a narrow work place can be easily performed.
