DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the cultivation bed cultivation apparatus of the present invention will be described with reference to FIGS. FIG.
It is a perspective view showing the structure of one embodiment of the cultivation device of the present invention. 2 is a side view, FIG. 3 is a front view, and FIG. 4 is a plan view.
FIG. 5 is a front view in which a traveling wheel and a plowing tool part traveling on the upper edge of the side plate are extracted from the front view of FIG. 3, and FIG. 6 is a side view showing the bearing part of FIG. Also, FIG.
It is a perspective view showing the general arrangement | positioning layout of the cultivation bed in the greenhouse which uses this cultivation apparatus.

The cultivation bed cultivating apparatus comprises a frame 1, a wheel bracket 4 and a cover 5 as a whole structural member as shown in FIGS. 1 to 4, and a handle 2 is provided on a rear side surface in a traveling direction. An auxiliary handle 19 is connected to the front part in the traveling direction. Moreover, the support | pillar 3 is a foot at the time of temporary storage or storage in a barn, and also plays the role of a rough guide in the left-right alignment in relation to a cultivation bed.

Tire 7 running on the floor where the cultivation bed is installed
Are supported on the axle 12 via bearings (not shown) and are connected to the wheel bracket 4. Here, the tire 7 plays a role of a driving wheel, and a driving force is transmitted from the traveling geared motor 6 via a chain 7, an intermediate shaft 8, a sprocket 9, a chain 10, and a sprocket 11. (See Fig. 3)

Wheels 14 running on the upper edge of the cultivation bed side plate
Has a bearing (not shown) inside, is rotatably connected to the axle 13, and rolls on the bed while maintaining a constant distance between the frame 1 and the cultivation bed Z. A steel blade 19 as a plowing tool is connected to the axle 13 by an appropriate number of bolts, and the rotational force of a tilling motor 16 is transmitted via a chain 17.

On the other hand, the axle 13 is connected to the frame 1 via a bearing 18, and as a result, in this embodiment, the wheels 14 serve as rear wheels of the cultivation device, and the posture of the device is placed on the cultivation bed Z. We support that we always keep constant relations. In addition, the guide wheel 15 plays a role of keeping a constant horizontal distance between the present apparatus and the cultivation bed Z.

Next, the operation of the present embodiment will be described. First, an operator holds the handle 2 and carries the device out of the barn by treating the device as a two-wheeled vehicle that moves only by two tires 7, and tilts the device in a state where the device is inclined. Is set on the cultivation bed Z in such a manner that the blade 19 straddles the cultivation bed Z while taking care not to interfere with the edge of the cultivation bed Z.

At this time, the column 3 and the guide wheel 15 serve as a guide for accurately determining the position. When the blade 19 is dropped while rotating slowly, the cultivating apparatus moves the rear wheel 14 to the upper edge of the side plate of the cultivation bed. It is stably placed at the hit position.

Next, after the tilling motor 16 is rotated,
When the rotation of the traveling geared motor 6 is turned on, the present device runs over a cultivation bed and travels at a predetermined speed while tilling the culture medium in the cultivation bed.

When the cultivation of one cultivation bed is completed, the rotation of the tilling motor 16 and the traveling geared motor 6 is stopped, and the same operation as when the device is set on the cultivation bed is performed. Pull out, move to the next cultivation bed manually, and start tillage work again.

As described above, in the present apparatus, when moving from bed to bed, taking out from the barn, and storing in the barn, this apparatus can be handled by an operation like a two-wheeled vehicle, so that one person can easily handle it. And can be operated with two
Because it is a ring, it can turn around even in a narrow greenhouse with a small turn.

According to the second aspect of the present invention, the distance from the upper edge of the side plate of the cultivation bed to the cutting edge of the cultivating implement can be kept constant, so that the cutting edge can be approached to a minimum depth without contact with the bottom plate of the cultivating bed. It is possible to cultivate the medium in the medium casing of the cultivation bed everywhere, and a uniform and optimal medium can be realized.

Also, the role of the guide wheel 15 on the left and right sides makes it possible to bring the blade edge close to the edge of the side plate of the cultivation bed, so that a uniform and optimal medium can be realized.

Furthermore, if the running wheels on the cultivation bed installation floor are used as drive wheels as in the present embodiment, the floor surface is usually a soil surface, so that the case where the top edge of the side plate of the cultivation bed is driven is driven. In comparison, the coefficient of friction with the running wheels can be increased, and a stable running state can be realized. As a result, the medium cultivation in a homogeneous and optimal state can be efficiently realized.

In the above description, the present invention has been described in detail with respect to a specific embodiment. However, the present invention is not limited to such an embodiment, and various other various embodiments are within the scope of the present invention. It is obvious to those skilled in the art that the embodiments are possible. For example, the motor may be a belt or a gear instead of a chain drive, or may be a direct drive. Further, an internal combustion engine may be used as the driving means.

The wheels running on the upper edge of the side plate of the cultivation bed may be provided with a flange, and the guide wheel 15 may be omitted.
If the dimensions allow, the bearing 18 interposed between the frame 1 and the axle 13 may be arranged inside the traveling wheel 14 to reduce the frame width.

In the present embodiment, in consideration of the balance during manual movement, motors, which are heavy objects, are arranged above the traveling tire 7, and the center of gravity of the entire apparatus is placed near the traveling tire. However, it can be moved to another position due to restrictions on operability and other functions.

[0028]

According to the cultivation device of the present invention, the setting of the device on the cultivation bed and the manual movement of the device are easy and can be easily operated by one person. Can be strongly promoted. Also, during manual operation, 2
Since it is handled as a wheeled vehicle, it is easy to handle and the turning radius can be reduced, so that the passage area can be minimized in the valuable greenhouse space, and the economic efficiency is improved.

Further, the present invention is economical because there is no need for a transport cart or a hoist device for moving the apparatus. Furthermore, by lifting the handle of the device, the device can be easily tilted, and the replacement, maintenance and disinfection of the consumable blade can be easily performed, and the working time can be reduced. it can.

In addition, since more than half of the weight of the present apparatus is taken up by the tires running on the floor on which the cultivation bed is installed, the load on the side plate of the cultivation bed is reduced, which is a favorable condition for the deterioration of the side plate. In addition, the automatic tilling work can be applied to a conventional delicate side plate cultivation bed.
