Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural machine, for example, an agricultural work vehicle used for harvesting strawberry-grown berries.

[0002]

2. Description of the Related Art Among the conventional agricultural work, the strawberry harvesting work is rarely mechanized, and is performed manually. Usually, strawberries are cultivated in high ridges, and in the work of picking strawberry fruits, the fruits hanging on the ridges or between the ridges are bent while bending over. Therefore, such a long working posture causes backaches and headaches, which is one of the causes of strawberry production loss and lack of successors.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an agricultural work vehicle for facilitating agricultural work and improving work efficiency.

[0004]

In order to solve the above problems, an agricultural work vehicle of the present invention is provided with a vehicle body that reciprocates in the front-rear direction along a ridge, and a vehicle body provided on the vehicle body to allow a worker to sit and work. And a slide mechanism for sliding the swivel chair along the traveling direction of the vehicle body.

[0005]

[Operation] For the agricultural products that are ridge-grown, the worker
The orientation position of the swivel chair is adjusted in accordance with the traveling direction of the agricultural work vehicle so that the agricultural work can be performed while sitting in the swivel chair provided in the agricultural work vehicle and facing the traveling direction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an agricultural work vehicle according to the present invention will be described with reference to the drawings. In this embodiment, the farm work vehicle is
It is configured as a harvesting work vehicle that harvests strawberry fruits. FIG. 1 is a side view of a harvesting work vehicle showing an embodiment of the present invention, and FIG. 2 is a front view thereof.

The harvesting work vehicle 1 is a four-wheeled vehicle that is symmetrical in the front-rear direction and in the left-right direction. Each wheel unit 2 includes a pair of tires 2a and 2b adjacent in the width direction. Each wheel unit 2 is independently driven in the front-rear direction by an electric motor 6 provided on a frame 5 located above each wheel unit, for example.

The widthwise wheels are connected to each other by a U-shaped upper frame 10, and the ends of these upper frames 10 are connected to the frame 5. The lower side of the frame 5 of the front and rear wheel portions is connected by a U-shaped lower frame 12, and the lower frame 12 is located between the left and right front wheel portions and between the right and left front wheel portions, respectively. The left and right lower frames 12 are
They are paired, and the height from the ground is set to about 15 cm so that it is suitable for picking strawberries.

A rotating chair 20 which slides along the frame is arranged on the pair of lower frames 12,
The worker is supposed to work while sitting on the swivel chair 20. A specific configuration example of the swivel chair 20 will be described with reference to FIG.

A sliding member 25 having roller-shaped rollers is arranged on the pair of lower frames 12, and the sliding member itself can slide along the frame. A swivel chair 20 having a low height and a backrest 20a is attached to the sliding member 25. This swivel chair 20
Is rotatable 180 ° or 360 ° and is preferably configured to be locked when in the position shown in FIG. That is, the swivel chair 20 is
It can be placed in the state of being positioned on the left side as shown in FIG. 1 and the state of being rotated by 180 ° and positioned on the right side.
Such a seat 20 is arranged between the front and rear wheel parts on the left side and between the front and rear wheel parts on the right side so that two workers can ride on the harvesting vehicle.

The horizontal frame 10 of the upper frame 10
a, a harvest box mounting table 35 for mounting the harvest box 30;
The harvest box mounting table 35 is configured to be mounted on the horizontal frame 10a of either the front or rear upper frame 10.

Next, the harvesting work for harvesting strawberry fruits using this harvesting work vehicle will be described. First, the harvesting work vehicle is prepared so as to straddle one ridge so that the left and right wheel portions are aligned with the groove of the ridge having the strawberry fruit, and the worker sits on each swivel chair 20. In this case, the swivel chair 20
Are arranged so that the harvesting vehicle is in the traveling direction.
That is, in FIG. 1, the harvesting work vehicle is in a state of traveling to the right. On the other hand, when the harvesting work vehicle moves to the left side, the harvesting box mounting base 35 and the harvesting box 30 are moved to the horizontal frame 10a of the left upper frame 10 in advance, and then the swivel chair 20 is rotated leftward and the frame 12 is rotated. Slide along. In such a position of the swivel chair 20, as the harvesting work vehicle is driven and moves along the groove of the ridge, the worker sitting on the swivel chair 20 picks the strawberries that have grown on the left and right ridges. Put the picked strawberries in the harvest box 30 in front of you.

As described above, since the worker sits on the swivel chair 20 and collects strawberries, the picked strawberries can be simply put in the harvest box 30 in front of him. , It is no longer necessary to bend down and be forced into a cramped work posture for a long time. Moreover, since the worker performs the harvesting work while sitting in the traveling direction with the swivel chair, the work efficiency can be improved and the headache and other diseases are not caused. Furthermore, the harvesting vehicle itself is configured symmetrically in the front-rear direction to move forward and backward, and reciprocating work can be performed, thereby improving work efficiency.

The electric motor 6 and each wheel portion 2 are controlled so that the drive direction and the rotation thereof are controlled by a controller in a control box 50 placed on a mounting table provided at a substantially central portion of the upper frame 10. The front and rear driving along the ridges and the movement between the ridges are controlled according to a predetermined program.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, but can be variously modified as described below.

The number of tires provided on the wheel portion may be singular rather than plural. The overall size, the shape of each component, the material used, and the like can be appropriately modified depending on the size of the ridge, the crop to be cultivated, the environment, and the like. If the frame 5 provided with the wheel portion 2 is configured to be expandable and contractable in the width direction, it is possible to deal with ridges of various sizes. If you can adjust the height of the swivel chair 20,
It can accommodate ridges of various heights. When the harvesting vehicle is used in a greenhouse, it is preferable that the drive source is an electric motor as in the present embodiment, but other drive sources may be used. The drive source and the driving force transmission mechanism are configured such that each wheel unit is driven by using, for example, one drive source, in addition to those in which each wheel unit is independently driven as in the present embodiment. Is also good. Swivel chair 20
The slide mechanism that slides may use, for example, a frame 12 to sandwich and slide without using a roller-shaped roller. Further, the frame 12 may be composed of a single wide frame other than a plurality of adjacent frames.

[0017]

As described above, according to the present invention,
When high-ridge cultivation is carried out in a greenhouse such as a greenhouse, the work efficiency is improved because the harvesting vehicles that are symmetrically arranged can perform reciprocating work. In addition, the worker can work while sitting down, and when working forward and backward, the worker can change the sitting position and direction, so it is not necessary to work in a conventional cramped state, It does not cause backache, headache or other illness.
