[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail-running tea plantation that automatically manages tea plantations such as pruning and pruning of tea branches while automatically traveling along a laying rail laid between tea ridges. When operating the management device, it relates to a transport trolley for replacing the device on the track of another tea ridge at the headland at the end of the tea ridge. The present invention relates to a mobile trolley of an improved rail traveling tea garden management device.

[0002]

BACKGROUND OF THE INVENTION In recent years, when performing tea garden management work such as pruning of tea branches and leaves, pruning such as pruning and protecting insects and pests from insect pests, the work labor is reduced. Various attempts at automation have been made to improve the work efficiency. For example, in the case of tea ridges under favorable conditions, specifically, a relatively wide tea ridge on a flat ground or a gentle slope, a laying rail is provided between the tea ridges and the tea ridge is straddled on the laying rail. Run a gate-shaped traveling platform as described above, and use a rail traveling tea garden management device equipped with a tea garden management unit that directly performs the tea garden management work on this traveling platform, and perform tea garden management work in a state almost completely automated Attempts have been made to do so.

[0003] Such a rail-running tea plantation management device,
In a state where the predetermined tea garden management work is performed by traveling along the laying rails along the tea ridge, it is extremely effective to save labor.However, the tea garden management work for the tea ridge is completed, and the next A great deal of labor is required when moving to a tea ridge, or when removing or mounting a rail-traveling tea garden management device on a laying rail between tea ridges at the start or end of work. For this reason, a hand-held traveling type transport cart has conventionally been used, and a mounting rail that can be connected to the laying rail between the tea ridges is mounted on this. Alternatively, the rail-traveling tea garden management device was replaced from the laying rail to the mounting rail.

The applicant of the present invention has repeatedly improved and devised such a mobile trolley, and has succeeded in developing a mobile trolley having improved functionality so as to be able to cope with various types of tea gardens. Japanese Patent Application Laid-Open No. 6-217624, entitled "Mounting stand for rail-running tea garden management cart". This is provided with a function of enabling the mobile trolley to select a posture in a three-dimensional direction including turning and lifting, thereby trying to cope with various types of tea gardens.

However, the above-mentioned Japanese Patent Application No. Hei 6-217624.
In the mobile trolley disclosed in No. 5, the size of the tea plantation, in particular, depending on the situation of the headland, it may be required to increase the size, as a result, such a mobile trolley is mounted on the carrier of the vehicle This caused a situation in which the handling of transportation was impaired. In this regard, FIG.
This will be specifically described based on the following. First, as shown in FIG. 7A, assuming a tea garden in which the tea ridge L and the headland M are inclined and do not intersect at a right angle, a design specification of the mobile trolley 1 'corresponding to such a tea garden is considered. View.

In this case, the placing rail 6 'connected to the laying rail R is arranged so as to be located on an extension straight line of the laying rail R, so that the tea garden management device 2 is inevitably attached to the moving cart 1'. It will be supported in an inclined state.
Accordingly, the mounting rail 6 'requires an extra portion indicated by reference numeral a in FIG. 7A, and the carriage width b of the moving carriage 1' is also increased by the mounting rail 6 'by the excess portion a. It is larger than On the other hand, when the moving trolley 1 'designed based on such conditions is used in a tea garden where the tea ridge L and the headland M cross at a right angle as shown in FIG. 7B, the moving trolley 1' Is larger than the tea garden management device 2 only in the surplus portion a, and it can be understood that the increase in the width b of the cart is meaningless in the tea garden.

In view of such circumstances, taking into account the size of the tea garden management device 2, the distance between the laying rails R, the maximum inclination angle between the tea ridge L and the headland M, etc., If the carriage width b is set, it becomes about 2100 mm. On the other hand, the bed width of a small truck having a maximum loading capacity of about 1 to 1.5 ton which many tea farmers own is 1690.
mm or 1695 mm is generally used. When the transporting trolley 1 'having the above-mentioned trolley width b is loaded on the loading platform of such a small truck, the transporting trolley 1' naturally moves from the platform of the small truck. It will protrude, and it will not be able to be transported unless the side of the carrier is opened, leaving a problem in terms of safety as well as legal requirements. In addition, as the size of the mobile trolley 1 'increases, the weight and material cost of the trolley increase, and the handling of the mobile trolley 1' is not always sufficient.

[0008]

[Technical Matters Attempted to Be Developed] The present invention fully recognizes such a background and has been devised based on the recognition, and is a function required for a mobile cart used in a tea garden. Development of a new truck with a new rail-traveling tea garden management device, which does not impair this at all, by reducing the size of the truck by changing the frame structure of the truck, and thereby improving the above-mentioned on-board transportability. I tried.

Then, the traveling wheel 41 is attached to an attachment bracket 42 provided near the center of the moving means attachment frame 31, and when the rail traveling type tea garden management device 2 is transported to another tea garden slightly away, the traveling frame 41 is further attached to the attachment frame 33. Then, the hand push handle is attached, the hand push handle is held in a hand, and the transfer cart 1 is moved to the other tea garden while pushing the hand push handle by hand. On the other hand, when the tea garden management device 2 is far away from the rail-running tea garden management device 2, or when the day-long tea garden management work is completed and returned to a warehouse or the like in which the rail-running tea garden management device 2 is stored, the vehicle is temporarily stopped. It is transferred to the carrier c and transported.

In this case, the user pushes the hand-held handle with his / her hand, and moves the carriage 1 to the rear of the cargo bed c of the vehicle while pushing the handle by hand. At this time, the vehicle carrier c
All the tilts are left open, and a guide inclined plate (not shown) for transfer assistance is provided at an appropriate position at the rear end of the loading platform where the traveling wheel 41 of the moving vehicle 1 passes. And, while paying attention that the running wheel 41 rests on the guide inclined plate,
By pushing the hand push handle by hand, the transport trolley 1 loaded with the rail-running tea garden management device 2 is transferred to the carrier c of the vehicle.

Then, if necessary, the traveling wheels 41 are stored, the tilt of the loading platform c is raised, and this is closed, and then the rail traveling tea garden management device 2 is placed on the loading platform c of the vehicle by an appropriate fixing means. Then, the carriage 1 is fixed and transported to the destination.
