Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cultivation device used when cultivating soil in a cultivation bed containing cultivation soil in a soil storage casing.

[Conventional technology]

Conventionally, as a cultivation bed, there is one in which a soil storage casing having a substantially U-shaped cross section is filled with cultivation soil.

In such cultivation beds, when the cultivation soil is tilled, an operator uses a hoe, a tiller, or the like.

[Problems with conventional technology]

However, since the casing of the cultivation bed was installed at a higher position than the ground surface through an intervening object, the worker had to enter the casing and hoe the cultivation bed.
The work had to be done with a tiller or the like, and as a result, there was an inconvenience that tilling work was nothing but hard labor.

[Means for solving problems]

This invention has been made to solve the above-mentioned inconvenience, and has a structure that includes a soil storage casing and a cultivation device, the cultivation soil is stored in the casing, and the cultivation soil is cultivated by the cultivation device. In a cultivating device for a cultivation bed, the casing is formed into a substantially U-shaped cross section by protruding side plates on both edges of the substrate, and a running wheel is installed on this cultivating device via an axle. ,
The cultivation device is placed on the upper edge of the side plate via the running wheel, and the running wheel is appropriately rotated by a drive means to move the cultivation device along the upper edge of the side plate. This is a unique cultivating device for cultivation beds.

[Action of the invention]

A cultivation device for a cultivation bed according to the present invention includes a soil storage casing and a cultivation device, the cultivation soil is stored in the casing, and the cultivation soil is cultivated by the cultivation device. , the casing is formed into a substantially U-shaped cross section by protruding side plates on both edges of the base plate, and a running wheel is installed on the cultivation device via an axle,
The cultivation device is placed on the upper edge of the side plate via the running wheel, and the cultivation device is moved along the upper edge of the side plate by appropriately rotating the running wheel by a drive means. Therefore, by operating the running wheels, the cultivation device can be moved along the longitudinal direction of the casing (cultivation bed).

[Explanation of Examples]

Embodiments of the present invention will be described below based on the drawings.

In FIGS. 1 to 4, reference numeral 1 denotes a soil storage casing for a cultivation bed, which is installed on the ground surface 3 via intervening objects 2, such as blocks. This casing 1 includes side plates 12 on both ends of a substrate 11,
12 is integrally molded into a substantially U-shape (see FIGS. 3 and 4), and accommodates cultivation soil (not shown). Note that 121, 121 are curved edges formed at the tips of the side plates 12, 12,
This is a location that supports running wheels 51, 51, 61, and 61, which will be described later.

On the other hand, 4 is a frame of the cultivation device P, which is constructed by integrally forming support plates 42, 42 on both end edges of an upper plate 41 in a substantially inverted U shape (see FIGS. 3 and 4). 5 is a support plate 4 of the frame 4;
The driving axles 51 and 51 passing through the axles 2 and 42 are traction running wheels pivotally supported by the axle 5. Note that 52 is a sprocket, which is fitted onto the driving axle 5. On the other hand, 6 is a driven axle, which, like the driving axle 5, is installed on the support plates 42, 42. This driven axle 6 includes driven running wheels 61,
61 is pivotally supported. The traction running wheels 51, 5
1 and the driven wheels 61, 61 are connected to the curved edges 1 of the side plates 12, 12 of the casing (cultivation bed) 1.
It is placed on 21,121. Reference numeral 54 denotes a driving motor, which is fixed to the upper plate 41 of the frame 4 via a bracket 541. This driving motor 54 has a sprocket 542, and this sprocket 542 is connected to the sprocket 5 of the driving axle 5.
2 and chain 55. Therefore, when the driving motor 54 is driven, the traction running wheels 51, 51 rotate via the sprocket 542, the chain 55, and the sprocket (of the driving axle 5) 52, and the tillage device P moves in the direction of the arrow (Figs. 1 and 5). (See Figure 2).

Next, in FIG. 4, 7 is an operating shaft, and between the driving axle 5 and the driven axle 6,
It passes through the support plates 42, 42 of the frame 4. A sprocket 71 is detachably fixed to one end of the operating shaft 7 by a locking pin 711. A support bush 72 is detachably fixed to the other end of the operating shaft 7 by a locking pin 721. This support bush 72 prevents the actuating shaft 7 from moving in the axial direction. Reference numeral 73 denotes a boss portion of the cultivation tool A, which is externally fitted onto the operating shaft 7. This boss portion 73 is removably fixed to the operating shaft 7 by a locking pin 731 (see FIG. 4). 74, 74, . . . are plow plates, which are protruded from the circumferential surface of the boss portion 73 at intervals of 90 degrees. The curved ends of the plow plates 74, 74,...
The directions are sequentially reversed in the circumferential direction of the boss portion 73. 75 is a prime mover for tillage, 76 is a speed reducer, and both 75 and 76 are attached to the upper plate 4 of the frame 4.
1 is screwed on. The rotational force of this prime mover 75 is transmitted to a reduction gear 76 via a chain 77, and is reduced by this reduction gear 76 at an appropriate rate. 761 is an output sprocket of the speed reducer 76, which is connected to the sprocket 71 of the operating shaft (of the tillage implement A) 7 via a chain 78.
Therefore, when the tillage prime mover 75 is driven, the operating shaft 7 and eventually the boss portion 73 are rotated via the speed reducer 76, and the plow plates 74, 74, . . . are operated, and the cultivation soil in the casing 1 is tilled. .

Next, the ridge shaping device B will be explained based on FIGS. 1, 2, and 5.

411, 411 are locking bushes, which are welded to the rear part (with respect to the traveling direction) of the upper plate 41 of the frame 4. Further, 8 is a holding plate, and locking pins 81, 81, 81 are provided protruding from the tip end edge. This retaining plate 8 has locking pins 81, 8
1,81 to the locking bushes 411,41 of the upper plate 41
1, the frame 4 is removably installed. 9 is a shaping board, and 9 is an auxiliary board.
It is welded to the lower part of the retaining plate 8 via 1, 91, 91. This shaping plate 9 has an inverted U-shaped cross section, and as the cultivation device P advances, it strokes the tilled soil from above to form it into a predetermined shape (forms a ridge S). Reference numeral 92 denotes an enlarged diameter portion, which is integrally molded at the front end of the shaping plate 9. This enlarged diameter part 9
2 gradually expands in diameter as it goes in the direction of movement of the cultivation device P, making it easier to take in the cultivated soil into the shaping plate 9. When the tilled soil is shaped by the shaping device B, it is desirable to collect the tilled soil in the center of the casing 4 using the tilling device shown in FIG.

The operation of this cultivation device P will be explained.

First, the cultivation prime mover 75 is driven together with the traveling prime mover 54. Then, the traction running wheels 51, 51 are rotated via the chain 55, and the plow plates 74, 7 are rotated via the reducer 76 and the chain 78.
4,... rotate, and as a result, the cultivation device P moves along the casing (cultivation bed) 1, and the cultivation soil within the casing (cultivation bed) 1 is tilled. The cultivated soil is stroked from above by the shaping plate 9 as the cultivation device P advances, thereby forming a ridge S in the casing (cultivation bed) 1.

In this embodiment, a traction running wheel and a driven running wheel are used as running wheels, but both may be used as traction running wheels.
