A tool for placing growing pots apart and in rows

The present invention relates to a tool for splitting and placing growing pots in rows, wherein the tool consists of a lifting device with a handle and a toothed transverse bar.

The method for arranging pots in greenhouses is as follows: 10 Growing pots are filled in the ground either mechanically or by hand. The seedling or seed is planted in each pot.

When the pots are ready, they are transferred to a transport trolley and placed side by side close to each other and in layers on top of each other. This is done manually.

15 The transport wagon is then moved to the growing benches, where the pots are moved to the benches. This is also done by hand. Pots are usually placed close together or at some distance from each other depending on the size of the press and the growth rate.

20 It is also possible to move the pots from the transport trolley using a simple tool. Such a tool is described in Norwegian Patent No. 138,012. The described tool is molded into a handle connected to a transverse bar to which a group of forward-facing teeth is connected.

25 As plants grow and the leaves spread over the edge of the pot, they need more space and more light. If the pots are not now moved apart, plant growth will paralyze. Separation is performed by moving every other pot by hand and placing it on a second growth bench and at a good distance from each other.

It is clear that handling pots in greenhouses is time consuming and labor intensive. As a result, there has been a long-standing desire that the separation of plants could be performed mechanically or with a suitable tool.

Norwegian Patent No. 136,170 describes a tool which is well suited for moving one row of pots apart from 2,689,493 other rows on a growing bench. With this tool, every other row of pots is moved off the bench. The pots that are moved away are placed on another bench in the same order in which they were moved away. The pot 5 left on the bench must then be spread by hand in such a way that every other pot is moved perpendicularly one place to the empty row.

However, the above tool will only do its job if the plants are placed at a certain distance from each other.

10 If they are placed too close together, moving the pots will damage the plants.

Although the above-mentioned tool has to some extent rationalized the separation work, some remarks have been made against it due to the fact that the separation has to be performed manually.

The conclusion was that, to date, placement with tools has not been good enough. Another thing is that the gardener needs to have both of these tools at their disposal.

The prior art NO patent application No. 810 668 describes a fork for placing and placing growing pots in rows of the type consisting of a lifting device with a handle and a toothed transverse bar.

25 This separation fork is very suitable for small and large pots containing plants whose leaf crown is not too developed. It is therefore particularly useful in growing seedlings.

In cases where the leaf crowns are well developed and when the leaf crowns of two or more adjacent plants are intertwined, it has been found that the segregation fork has certain disadvantages because the plants have to be separated from each other. This slows down the relocation work done with the tool.

35 When pots are moved out of the growing bench, the most important thing is that this is done as rationally as possible. In other words, the number of pots spaced 3 68493 apart per unit time should be as large as possible. For example, one row at a time can be moved apart with a long fork or two rows at a time with a shorter fork. On both occasions, the same number of pots per unit time is transferred separately.

However, it is more difficult to place apart with a long fork than with a shorter one because the former fork is more difficult for the gardener to handle.

The inventor has now shown that when the teeth of the separation fork are shaped in a special way and that the teeth can be arranged in a fixed position above the support by a simple operation, the problem can be solved with a combination tool for lifting and placing pots apart.

An essential feature of the invention is that every other pair of teeth is connected to the lowest and every other to the upper transverse bar, where the upper and lower transverse bars are independently displaceable relative to each other.

Another feature of the invention is that the teeth have a preferred parallelepiped cross-section, but no other restrictions are placed on the shape of the teeth or their mutual arrangement.

For example, when lifting and placing one row of pots apart, the teeth may have the shape of a parallelepiped 25 as seen from front to back.

However, if two rows of pots have to be spaced apart on the same fork, then according to the invention every other pair of teeth is parallelepiped shaped and every other pair of teeth is parallelepiped shaped from the front of the tooth and bent to the side and above the other pair of teeth at the back of the tooth.

The separation fork further has a preferred embodiment, where it is provided with a simple device such as a handle and a handle. The function of the handle when moving it up is to lift every other pair of teeth from the support. The lower crossbar of the separation fork- __- - li _____ 68493 bar then remains with support as a variable height adjuster for the fork.

When placing the plants apart by means of a separation hook-Ruka, each other pot is raised so high 5 that the leaf crowns are kept separate from each other.

The invention is as described in the claims.

For a better understanding of the invention, reference is made to Figures 1-4 and the labor savings shown below:

Manual segregation only 0% savings 10 2 tools and manual segregation approx. 25% savings

The segregation fork according to the invention saves about 75%

Fig. 1 is a plan view of said separation fork, while Fig. 2a shows the same in section along the line A-A.

Fig. 2b shows a cross-sectional view of the teeth 3a and 3b along the line B-B.

Figures 3 and 4a show the pots in rows seen from above and interleaved.

The separation fork for moving the growing pots is shown in its entirety in Figure 1. The separation fork is provided with a handle (1), an upper transverse bar (2) and forward-facing teeth (3), which in the present case are connected to the rod (2) and the lower, not on the visible bar (4). This detail 25 is more clearly seen in Figure 2a.

The teeth are grouped into pairs (3a) and (3b) so that the pair (3a) is connected to the upper transverse bar (4) while the pair of teeth (3b) are connected to the lower transverse bar (2). Another feature shown is the plate area (5), 30 on the back of every second pair of teeth (3b).

Figure 2a shows a cross-section of the separation fork along the line A-A with the handle (1) and the sliding housing (6) to which the handle (7) is attached. In the present embodiment, the lower crossbar (4) is connected to 35 lifting devices (8). The teeth (3a) and (3b) are connected to the transverse bars (2) and (4), respectively. The beam rod (2) is connected to a sliding housing (6), to which the handle (7) is also connected. The handle can be pulled upwards towards the handle (1), with which the entire row of teeth (3a) and the transverse bar (2) are lifted.

The rear part of the tooth (3a) has a shaded part (5) above the tooth-5 head (3b).

Fig. 2b shows this detail better, as it shows a cross-section of both teeth (3a and 3b) along the line BB in Fig. 2a. It can be clearly seen how the tooth (3a) is shaped from the back of the tooth with the outer (5) tooth (3b) above.

To explain how this particular detail works, attention is drawn to Figures 3 and 4a and 4b, which show 2 rows of pots in non-interlaced and interlaced, respectively. Interleaving is performed so that the entire row of teeth is placed between two rows of pots. By pulling the handle (7) upwards towards the handle (1), all the pots in the row closest to the gardener (row B, Fig. 3) remain hanging from the teeth (3a) while only every other pot furthest from the gardener (row A, 20 Fig. 3) hangs from the teeth (3a). The other side of the pots in this row thus remains hanging on the teeth (3b).

Using a segregation fork as a transfer device

If a separation fork is to be used to move the growing pots from one bench to another or to the carriage 25 and out of the carriage, the teeth of the separation fork are placed between the pots, after which the rows of pots are raised. The pots thus remain hanging on the teeth (3).

Using the separation fork as a separation device 30 If the fork is to be used to separate the pots in the rows, the teeth (3) should be placed between the pots. The handle (7) is then pulled upwards towards the handle (1), indicated by the double arrow in Figure 2a. The pots are thus placed on different levels. The lower tum-35 unpaved pot layer, the layer that hangs on the teeth (3b) when the two rows of pots A and B have been raised by the separation fork, can now be placed on the supports.

6 68493

The upper shaded pot layer, with the pots depending on the pairs of teeth (3a), can now be pulled out of the lower row of pots and placed on a support, i. interlaced on the growth bench, as shown in Figure 4a.

5 The separation fork is then pulled back so that the foremost part of the teeth intersects with the row of pots B. The entire row of teeth (3a) is then raised by means of the handle (7) so that every second pot is raised from the row of teeth (3a) and every other pot from the row of teeth (3b) and the same is repeated as mentioned above when placing the first row (row). A) apart.

Using the old methods and only manual handling of the pots, a lot of time was spent placing them in the transport wagon and from them to the benches and from the benches again to the Vau-15 zero or another bench before the pots could be placed separately.

The present invention is not limited to pulling out and splitting one or two rows of pots at the same time, because the additional extension of the pairs of teeth (3a and 3b) would cause the teeth to interleave with more than two rows of pots. The protrusion (5) of the teeth (3a) must therefore in this case be extended in relation to the length of the teeth.

By using a simple lifting device with a plurality of parallel teeth, it is possible to simultaneously lift a plurality of pots in rows in a carriage and on a bench and from a bench to a carriage or to another bench.

The next segregation of every other pot was then done by hand. The time savings achieved with this method are, as previously discussed, about 25% of what is required for manual operation.

The advantages of the present invention are that the object of the invention, the separation fork, can be used at the same time as a lifting device for several pots arranged in rows one behind the other and for interleaving pots in the same rows, and that the user can effectively separate stuck leaf chandeliers.

Studies have been carried out which show that, compared to the manual transfer and interleaving of pots, about 75% of the normal working time is saved when using the segregation fork according to the invention.
