[0001]
BACKGROUND OF THE INVENTION
According to the present invention, a variety of management machines such as a pruning machine for pruning tea trunks, a plucking machine for plucking tea leaves (tea buds), or a control machine for spraying chemicals can be selectively selected for one traveling machine. It is related to a management machine that attaches and manages tea gardens, and is a new straddle type that improves the efficiency of various management work by making it easy to attach and detach the entire storage part used especially during plucking work It relates to tea garden management machines.
[0002]
BACKGROUND OF THE INVENTION
For example, with respect to a crawler-type traveling machine that travels across a teacup, an appropriate management machine such as a pruning machine, a plucking machine, or a control machine is supported on the top surface of the teacup according to the work. However, such a management machine is usually provided with a tea leaf container used at the time of plucking work behind the management machine body. For example, when performing a mid-cutting operation which is one of the pruning operations by such a management machine, it is possible to attach the mid-cutting machine body to the plucking machine body mounting position, that is, the substantially central portion of the traveling machine body or the rear position of the traveling machine body. There were many.
[0003]
In this way, when the intermediate mower body is attached to the plucking machine body attachment position, the intermediate mower body is located at the approximate center of the traveling body, so that the mowing can be carried out at an average position with respect to the unevenness of the field, but the harvesting is performed. As for the branches and leaves, this thing tends to be clogged by crawlers etc. of the traveling aircraft by being bounced back by, for example, the tea leaf container that constitutes the tea leaf container, etc. There is a problem that it takes a lot of trouble. On the other hand, with regard to such a tea leaf storage base, there is a management machine in which this can be rotated from a substantially horizontal direction to a substantially vertical direction, so to speak, it is said that it escapes from the rear. It was a technique mainly aimed at shortening the dimensions and improving the ease of handling such as turning. For this reason, in many cases, only the rear portion of the tea leaf storage table is configured to be rotatable, and the front portion of the tea leaf storage table, the so-called Earl table, is originally fixedly attached to a slider that supports the management machine body so as to be movable up and down. Most of the forms are present, and as long as this areal stand is present immediately after the mid-cutting machine body, the above-mentioned problem of clogging of branches and leaves has not been solved.
[0004]
In addition, when attaching the middle trimming machine body to the rear position of the traveling machine body, it is good in that the cut leaves are not clogged by the crawler etc., but compared with the case where it is attached to the picking machine body mounting position, When pitching (pitch) is large and there are convex parts on the field, there is a drawback that steps are easily formed before and after the cutting surface. In addition, in many management machines in which the Earl stand is fixedly attached to a slider formed to be movable up and down, even if the rear part of the tea leaf receiving stand is rotated to rise almost vertically, As a result, the rear extension dimension of the management machine is inevitably long, and a space for turning the management machine is also required, which is a factor that reduces the handling of the management machine. It was.

The air duct 35 is disposed obliquely above and forward of the cutting blade 34. The cutting blade 34 is provided on the front extension of the plucking machine frame substrate 32.
[0014]
Next, the accommodating part 4 is demonstrated. The accommodating part 4 is a part which accommodates the picked tea leaves, and is used during normal picking work among various management work. And the accommodating part 4 is formed in the curved surface shape which follows a teacup T upper surface substantially, and as shown in FIG. 1, 2, as an example, the said slider 25 is located in the substantially back of the cutting blade 34. As shown in FIG. It is provided with an arel base 41 that is detachably attached to the storage base 42 and a storage base 42 for substantially placing a collection bag for storing tea leaves.
The round base 41 connects the plucking machine frame substrate 32 and the storage base 42, and a contact portion 43 that is hooked on the contact receiving portion 28 of the slider 25 is formed at the tip portion. Engaging protrusions 44 that engage with the engaging holes 27c of the slider 25 are formed at substantially the center of both ends, and are easily and reliably held by the holding bracket 27 and the contact receiving portion 28.
The accommodating table 42 is connected to the rear side of the R-shaped table 41, and is configured to be rotatable by extension / contraction of a slider 45a of a hydraulic cylinder 45 provided in a fixed state from the slider 25 as an example. It is stored in a state where it is raised in the direction. Incidentally, the tea leaf storage table described in the “Background of the Invention” in the present specification means both the above-mentioned R table 41 and the storage table 42.
[0015]
Next, the attachment / detachment aspect of the accommodating part 4 in the straddle-type tea garden management machine 1 comprised as mentioned above is demonstrated. In the description, an attachment state in which the accommodating portion 4 is projected to the rear of the plucking machine body 30 will be described as an initial state.
(1) Initial state This attached state is a state during the operation of normally picking tea leaves, and a storage bag for storing the picked tea leaves is placed on the storage table 42 developed in the rearwardly protruding state. The In this initial state, as shown in FIG. 4A, the left and right ends of the round base 41 are held between the contact receiving portion 28 of the slider 25 and the holding bracket 27. Has been. Of course, in this state, the engagement protrusion 44 of the round base 41 is fitted into the engagement hole 27c of the slider 25.
[0016]
(2) Removal of storage base To remove the storage part 4 from this state, as shown in FIG. 4B, the connection of the slider 45a of the hydraulic cylinder 45 that rotatably supports the storage base 42 is released. .

That is, in the embodiment shown in FIGS. 1 to 4, the front-rear position of the management machine 3 is determined almost uniquely with respect to the slider 25. However, for example, as shown in FIG. 5, rollable wheels 36 are provided at both left and right ends of a management machine body 3 such as a pruning machine body, while a rail 29 that receives the wheels 36 is formed on the slider 25, and the management machine body 3 It is possible to adopt a form in which the motor is moved back and forth by a motor cylinder or the like. In addition, by having such a structure in the above-described straddling type tea garden management machine 1, the management machine body 3 can be easily moved to the rear of the crawler 22, that is, to the position where the R table 41 is attached. Pruning work according to various conditions such as sheath and finishing degree can be performed.
[0020]
The embodiment shown in FIGS. 1 to 4 has a basic structure in which the right and left ends of the round base 41 are held by the holding bracket 27 and the contact receiving portion 28 when the round base 41 is attached to the slider 25. It is what. However, for example, as shown in FIG. 6, it is possible to attach the bolt B such as a knurled bolt or a butterfly bolt by manual operation, or after the pin-like member is fitted into the slider 25 and the round base 41. Various attachment forms, such as a technique for preventing the removal by a clip or the like, can be adopted. In short, any form may be used as long as the R-table 41 can be easily attached and detached without using a tool.
[0021]
【The invention's effect】
According to the present invention, it is possible to remove the entire accommodating portion 4 for accommodating tea leaves other than at the time of plucking work such as pruning work. For example, the branches and leaves cut off at the time of intermediate cutting work are clogged by the crawler 22 or the like. This can be almost completely prevented. Moreover, since the attachment / detachment of the accommodating portion 4 can be performed without the need for a tool, the attachment / detachment work is easy, and it is not necessary to always have a tool. Furthermore, since the position of the management machine body 3 such as a pruning machine body can be set freely in the front-rear direction, it can cope with various conditions such as the depth of trimming and the degree of finishing thereof.
