Abstract

The subject of the invention relates to a device for extracting clods from plant-growing volumes for transplantation. It consists of the combination of an envelope of synthetic film 5 surrounding the clod 4 and placed in the growing volume 6, of a clod-lifting device 14 and mainly of a fork 1 formed by two parallel and horizontal or vertical needles. It is intended to make it possible mechanically to transfer the clod into a larger volume in any receiving surface.

Description

 The object of the invention relates to a device for extracting clods from the plant breeding capacities for transplantation.

 I1 is intended to mechanically allow the transfer of the root ball in a larger capacity in any receiving surface.

 Up to this day the transfer of the young plan ready to be put in a larger capacity or even in the ground was carried out by hand, it was necessary to take the breeding pot and seed, to dislodge it and place it in a capacity allowing its development, these operations were long and costly and could not be carried out lliécanquer.lert.

 i.e isù'osltlf according to the invention eliminates these drawbacks and allows for mechanical unloading of the plant with its root ball and its transfer in a larger capacity or in a tank or even in the ground.

 It consists of the combination of a synthetic film envelope enveloping the root ball and placed in the breeding capacity, a device for raising the root ball and mainly a fork formed by two parallel and horizontal or vertical needles.

In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 shows the root ball with its demodding film.

 Figure 2 shows the fork with transfer needle.

 Figure 3 shows the positioning of the elements.

 Figures 4, 5 show the packaging methods of breeding pots.

 Figure 6 is a schematic view showing the care of the root ball and its transfer.

 The device comprises as main element (fig 1, 2) a fork formed by two needles 1, 2 mounted on a transfer frame 3.

 The root ball 4 is preferably surrounded by a stripping film 5 and placed in a small culture pot in earth or synthetic resin 6.

 The breeding pot 7, 8 of the young plan is packaged in single-row packaging 9 or in multiple-row packaging 10, 11, 12 (fig 4, 5) mounted on a support positioned 13. They can also be staggered.

 These crates undergo the pushing of a rod 14 which detaches the root ball 4 and its film of demottling from the pot 6. The overhang 15 is then pierced by the points 12 (Fig 3) and "straddled" without the plant or its roots 16 are not reached.

 The points spread the roots and anchor themselves allowing the elevation of the demoulding arrow A (Figure 6) and the transfer to the large capacity 17, arrow B.

 At this moment the fork 1, 2 is withdrawn and the root ball 4 with its synthetic film for stripping butte against the gutter 18 and is freed from the forks to be deposited in the receiving container 17. A vertical movement can replace the stop and directly deposit the plan with its root ball at its point of use.

 The root ball can be -without synthetic demolding envelope, the roots and the compaction of the soil allow the insertion by needles 1, 2 without breaking.

 The pusher 14 passes through the axial orifice of the breeding pots. Any suitable means can be used for this raising, such as compressed air when the orifices are not axial.

 There are notches 19, 20 and the like at the location of the pots to reduce the amplitude and the raising or to eliminate it when the lumps are wrapped in a simple film of stripping.

 The fork is mounted on a frame connected to a jack or swiveling control system to ensure an elevation, arrow A ,.

 A translational movement arrow B, of elongation and finally a movement of withdrawal to release the root ball and disengage the needle fork, arrow C.

 These frames preset with respect to the packaging can be multiple and provide several transfers at the same time.

 The demoding and transfer rates can be very fast and thus eliminate costly handling without any damage to the root ball due to the thinness of the fork needles which, depending on the nature of the container, can be replaced by suitable interchangeable elements.

 However, the shapes, dimensions and arrangements of the various elements, as indeed the materials used for their manufacture may vary within the limit of equivalents, without changing for this, the general design of one invention which has just been described.

Claims (3)

 10 Device for extracting clods from the plant breeding capacities for transplantation intended to mechanically allow the transfer of the clod to a larger capacity or any other receiving surface, characterized by the combination of an extraction element and transfer formed by a fork constituted by two parallel and horizontal needles (1, 2) mounted on a load-bearing frame (3) with a clod (4) preferably wrapped in a stripping film (5) and contained in a small capacity positioned in a packaging (9) and undergoing a vertical push by a rod (14) ensuring a slight elevation in its pot (6).  20 Device according to claim 1 characterized in that the packaging (13) or (9) comprises one or more rows of pots (7, 8, 10, 11, 12) and may include notches (19, 20) facilitating the penetration of the needles (1, 2) in the root ball (4) in order to avoid if the root ball is only wrapped with a demolding film the elevation by pushing (14). These needles can be interchangeable with other gripping elements I  30 Device according to claim 1 characterized in that the fork (1, 2) performs a vertical translational movement by sliding in a support sheath (18) forming an extraction stop when the root ball (4) is positioned on the capacity receiver (17).
