Description

6671 3

The invention relates to a seedling honeycomb support frame comprising a horizontal handle made of a tube, connected at each end by two support arms which are attached at their lower ends to the seedling honeycomb support base.

Today, tree seedlings are grown in nurseries in plastic honeycombs with recesses for seedlings. The honeycombs are made of plastic sheet by deep drawing, whereby the thickness of the plastic sheet is considerably thinned. This method of manufacturing results in ken purchases which are light but do not have very high processing resistance. For this reason, a collar bent downwards from a plastic plate is made at the top of the honeycomb, the function of which is to stiffen the cell lift.

Due to the high cost of manufacturing the honeycombs, it would be desirable for the honeycombs to last as long as possible intact. But when transferring full honeycombs to the forest for planting, they are exposed to many stresses when the honeycombs are carried and loaded by hand. In practice, it has been found that cell failure is relatively common.

It is an object of the present invention to provide a device with which the honeycombs can be conveniently moved from one place to another without being damaged during the transfer.

The above object is achieved by a seedling cell carrier according to the invention, which is characterized by what is stated in the appended claims.

The invention will now be described in detail with reference to the accompanying drawings, in which Figure 1 shows a perspective view of an embodiment of a seedling cell carrier according to the invention, and Figure 2 shows another embodiment of a carrier.

According to Figure 1, the carrier has a horizontal handle 1 made of a tube, which is provided with a loop 2 for a possible hook. The handle 1 at each end of which is welded to the fixed sleeve 3 which is fixedly connected to the support arms 4 which are folded in alapääs-in the hooks 5 among whom ends of which are connected to the carrier laterally extending rail 6, which forms one side of the seedling tray support substrate and which extends as shown in Figure 1 under the stiffener collar of the seedling cell.

The other side of the seedling support base consists of a similar rail 6 running parallel to the previous rail and fixed to the lower ends of the hook-end movable support arms 7. The lateral movement of the support arms 7 is achieved by connecting them at their upper end to sleeves 8 placed against the inner edges of the sleeves 3, which can rotate freely around the tube 2 of the handle 1. When attaching the seedling honeycomb to its support base on the rails 6, the handle 2 is turned, whereby the support arms 4 fixedly connected to it turn sideways while the support arms 7 remain in a vertical position, the support rod 7 side rail B is placed under the seedling honeycomb collar. The handle 1 is then turned further so that the rail of the support arms 4 can be fitted under the collar on the other side edge of the honeycomb and the rack is lifted, whereby the seedling honeycomb remains on the support on the rack.

In the seedling honeycomb carrier according to Fig. 2, the support base for the honeycomb is formed by a rectangular basket 9, made of a tube, slightly larger than the dimensions of the honeycomb, into which the seedling honeycomb is placed. In this embodiment, a tube handle 1 with a loop 2 according to Fig. 1 is also used, the ends of which have sleeves 3.8 for fixed and movable support arms 4 and 7 placed against each other so that the movable sleeves 8 are inside the fixed sleeves 3. The fixed support arms 4 are provided at their lower ends with hooks 5 which can be fitted under a pipe on the other side edge of the car 9. The movable support arms 7, in turn, are connected to sleeves 10 which can rotate freely in a tube on the opposite side edge of the basket 9.

Figure 2 shows the carrier stand in its carrying position without lifting the seedling in the basket 9. When it is desired to remove the seedling from the basket 9, the basket 9 is placed on the ground, whereby the fixed support arms 4 lower and the hooks 5 release. When turned from the handle 1, the arms 4 move to the side and the hooks 5 can rise past the side tubes of the basket 9. Thereafter, by turning the handle 1 in the same direction, the support arms 4 can be turned completely around on the opposite side of the support arms 7, whereby the hooks come against the ground in their open position of the support rack, where the honeycomb can be removed and replaced.

The invention is not limited to the embodiments shown in the above description and drawing, but can be modified within the scope of the appended claims.
