t).

[0002]

BACKGROUND OF THE INVENTION Such soil pots are generally known in the horticultural industry.

The production of such a soil pot of rectangular cross section requires a considerable amount of soil.

This soil is quite expensive. The soil must ultimately meet the stringent requirements of nutrient content and the absence of bacteria and other pathogenic organisms.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a soil pot that uses less soil.

[0006]

The above object can be achieved by providing at least one groove in the sidewall of the soil pot.

The provision of the trench significantly reduces the soil requirements of such soil pots, so that the soil pots thus produced are cheaper and lighter than known soil pots.

The present invention also provides a method for manufacturing a soil pot, in which a groove is provided after compression in a method for manufacturing a soil pot, in which a compressed layer formed by supplying soil to a mold and compressing it from above is divided into a plurality of soil pots. And a method for manufacturing such a soil pot.

The present invention also relates to a device for manufacturing a soil pot according to the method described above, which device comprises a die for pressing,
A pressurizing member movable into the press mold and a cutting member, and an element movable to a position above the press mold for creating a groove in the compressed soil layer; Characterize.

[0010]

The present invention will now be described with reference to the accompanying drawings.

FIG. 1 shows a compressed soil layer 1 divided into a large number of soil pots 2. The figure shows the situation immediately after being compressed and divided into each soil pot.

Each soil pot 2 has a rectangular parallelepiped shape, and has a horizontal square cross section in this embodiment.

It can be seen from FIG. 1 that a recess 3 is provided in the center of the upper surface of each soil pot 2 for receiving a capsule containing seeds. Further, a groove 4 is provided on each sidewall of the soil pot 2. This groove 4 runs vertically and is obtained by boring or punching from the top.

FIG. 2 shows a single unit of the soil pot 2 shown as a group in FIG. Here, it can be seen that each sidewall of the soil pot 2 is provided with a groove 4 having a semicircular cross section. When manufacturing such soil pots as a group, grooves of semi-circular cross section are clearly attractive as they can be provided in two adjacent pots with a single boring or punching action. Also, grooves can be provided at the corner edges.

An example thereof is shown in FIG. Here, the grooves 5 are provided at the edges of all four corners. It is clear that such a groove with a quadrant shape is also easily obtained by boring. The amount of soil removed using a drill having the same diameter as that of the embodiment shown in FIG. 2 is about half. The surface area of four quadrants is half that of four semicircles.

The embodiment of FIG. 2 has the advantage over the embodiment of FIG. 3 that it is easier to handle mechanically. It allows the pusher to engage across the entire width of the soil pot (except for the centrally located groove, of course), so the full width of the soil pot minus twice the radius of the corner groove This is because a larger moment is transmitted than in the case of the embodiment of FIG.

FIG. 4 further illustrates, for example, cutting (cu) at the corner edges.
An example in which the chamfered portion 6 is provided depending on the Such an embodiment has properties that roughly correspond to those of the embodiment of FIG.

Finally, FIG. 5 shows an embodiment of a soil pot according to the invention with horizontal grooves. Such a molding groove 7 can be provided at the same time as the compression of the soil pot, but it can be provided only in a separate process. In some cases, such a soil pot may be preferable. The handling properties of this soil pot are the same as the embodiment of the soil pot shown in FIG.

FIG. 6 shows a soil pot manufacturing apparatus. This device comprises a conveyor belt 8 on which a mold 9 is mounted.
In the first position, the feed hopper 10 feeds the mold 9 into the soil 11
To fill. Then the conveyor belt is one more position,
Moving. When the mold 9 thus formed reaches the second position, the press 12 descends until the soil 11 in the mold 9 is sufficiently compressed. The plane shape of the press 12 is the mold 9
It perfectly matches the inner plan shape of.

In this embodiment, the side edge of the mold 9 is provided with a plurality of semi-circular protrusions 13 for forming the groove 5 of the soil pot according to the embodiment of FIG. Therefore, the press 12 is provided with a plurality of corresponding notches 14.

After pressing, the press 12 moves up again and the mold 9 is filled with a layer of compressed material.

The mold is then moved on the conveyor belt 8 to the next position, above which the cutting device 15 is arranged. The cutting device 15 includes cutting blade plates 17 and 18 that extend vertically and intersect with each other.
Comprises a plate 16 provided on the underside. These cutting blades 17, 18 are used to divide the layers of compressed material in the mold 9 into individual soil pots.

The plate 16 is connected to the casing 20 by four supporting columns 19. The upper portion of the casing 20 can be moved vertically by the cylinder 21. Therefore, the piston rod 22 is arranged above the casing 20.

A hollow pipe 23 extending vertically is provided at each intersection of the cutting blade plates 17 and 18. Drill 2
4 extends through the hollow pipe 23, the upper end of which is a plate 16
And extends into the casing 20. A gear 25 is provided at the upper end of each drill 24 in the casing 20. Each gear 25 has one arrangement pattern (a pattern).
are arranged to engage one another according to ern of coordinates. One of the gears 25 has an electric motor 27 mounted on the upper surface of the casing 20.
A continuous shaft 26 driven by is provided. All gears 25 and also all drills 24 are driven by this shaft.

The space between the casing 20 and the plate 16 is connected to the air supply duct 58 and the air discharge duct 59. Air is supplied through the supply duct 58 and the discharge duct 5
By discharging through 9, the casing 20 and the plate 1
An air flow is generated through the space between 6 and 6, which carries away the soil removed by the drill.

When the cutting device 15 descends into the mold 9, the cutting blades 17, 18 divide the compacted soil into individual soil pots, while the drill 24 creates appropriate holes which form the appropriate grooves in the soil pots. It will be clear that it will be open.

It will also be apparent that the pattern of holes to be drilled can be modified by adapting the relative placement of the drills. For example, in the embodiment shown in FIG.
It is possible to make a groove at each corner of the soil pot,
On the other hand, in order to make a hole for a capsule containing seeds, a drill located in the middle of the space surrounded by the cutting blade plates 17 and 18 must be used. It is also possible to form the latter holes by pressing.

FIG. 9 is a diagram showing details of the embodiment shown in FIG. 6 when the positions of the hollow pipe 23 and the drill 24 are changed. Here, a twist drill is used to make a predetermined hole.

FIG. 10 shows an alternative embodiment in which the hollow pipe 23 is not provided with a separate drill, but a sharp cutting blade 28 is provided at the bottom of the hollow pipe 23.

For the embodiments according to FIGS. 9 and 10 above, it can be seen that the drill is always located in the center of the side wall. These devices thus serve to obtain a soil pot according to the embodiment shown in FIG.

The following several embodiments of the cutting device 15 are also suitable for obtaining a soil pot according to the embodiment of FIG. Arranged here at the position where the cutting blades 17, 18 intersect is a hollow drill 29, which is also driven by a gear 25, which is also driven by a suitable drive.

In the embodiment shown in FIG. 7, the plate 16 has been eliminated and the casing 20 has been arranged directly on top of the cutting blade plates 17, 18. As a result, the soil from the hollow drill 29 can be discharged from the upper surface of the casing 20. A scraping member 30 is provided for this purpose.

However, in the embodiment shown in FIG. 8, the relative arrangement in FIG. 6 is used again. Here, the soil is discharged into the space between the plate 16 and the gear casing 20 through a hole 31 drilled in a hollow drill 29. In both cases, the hollow drill 29 is equipped with internal threads 32.

In all the above-mentioned embodiments, the grooves which reduce the volume of the soil pot are always formed simultaneously. Of course, it is possible to make the grooves one by one, and the device required for that would be a much smaller and simpler device, although the groove creation time would increase significantly. For example, it is conceivable that a single drill moves to a soil accumulation place after drilling a groove, deposits the soil discharged by the drill there, and then moves to the next drilling position.

In the embodiment shown in FIG. 11, the soil pot 3
A row 35 of 6 is fed by a soil pot press 33 above a conveyor belt 34. The same row 35
As in the case of the embodiment shown in FIG. 6, it may be placed on a mold and moved on the conveyor belt 34, or it may be removed from the mold by hand or by an appropriate mold removing device after pressurizing and molding. May be placed on top. During the stepwise movement of the conveyor belt 34, this row 35 is brought under the punching device according to the invention. The punching device is composed of a frame 37 and piston rods 38 provided at four corners of the frame 37 and extending downward.
It extends into 9. Each cylinder is fixed to the base below it. In this way, the height of the frame 37 can be adjusted by the cylinder 39. The frame is a horizontal member 4
It is formed by two U-shaped cross-section members 40, each end of which is connected at 1.

A plate 42 is slidably fitted in the opposing opening of the U-shaped cross-section material 40. An electric motor 43 is installed on the plate 42, and its shaft is directly connected to a hollow drill 44 extending downward.

The hollow drill 44 is driven by an electric motor 43.

Flexible belts 45 are attached to both sides of the plate 42 and are operated around a shaft 46 provided on the lateral member 41.

One of the shafts 46 is driven by an electric motor 47 installed in contact with the frame. A motor 47 is used to move the plate 42 and thus the hollow drill 44 laterally with respect to the conveyor belt 34.

The frame 37 extends not only above the conveyor belt 34 but also above a hopper 48 provided adjacent to the conveyor belt. The hopper is fixed on a base 50 by legs 49, and a mandrel 52 extending downward is arranged in a second frame 51 above the hopper.

Below the hopper 48, a conveyor belt 53 leading to the soil pot press 33 is arranged.

When the conveyor belt 34 is stationary,
The holes are opened in the soil pot at appropriate positions by means of a hollow drill 44 which is driven to rotate, and the vertical movement of the drill device is carried out by a cylinder 39. When the hollow drill is full of soil, the plate 42 moves above the hopper 48, raising the entire frame and extending the mandrel 52 into the drill 44, pushing out the drilled-out soil therein. The device is then replaced again and the next hole is punched.

The soil discharged from the hollow drill drops into the hopper 48 and is conveyed to the soil pot press 33 by the conveyor belt 53.

It is also conceivable that the number of hollow drills is two or more. It is also possible to use fixed hollow pipes or other types of drills.
