Method and bag for drying and treating peat peat Förfarande och säck för torkning och behandling av mossbittorv

The invention relates to a method for drying and treating lump peat or the like, in which method the lumps made by the lump peat machine are dried in the bog in easily manageable batches.

The invention further relates to a sack for drying peat and possibly for transport, storage and other handling.

Generally, such peat is dried in the bog by applying it directly from the machine to the surface of the bog to dry. It can also be raked into 10 da furrows, which are then spread and turned if rain has gotten to wet the pieces.

In the known solution, the pieces are exposed to rain and thus drying them, especially in rainy times, is laborious and the result 15 still remains poor. Thus, the effective harvesting time is limited to a fairly short period in spring and early summer.

It is an object of the present invention to provide a method in which lump peat is readily available from the rain for shelter to dry in the bog and in which the peat is in a form that is easy to handle, transport and store.

The method of the invention is mainly characterized in that the peat is collected directly from the machine in sacks made of water-protective material on one side and air-permeable material on the other, and which sacks are placed in the bog to dry with the water-protecting side facing upwards.

The peat sack according to the invention, in turn, is mainly characterized in that one side of the sacks is made of a water-protective material and the other part of an air-permeable material, preferably a torn or reticulated film material. Sacks can be repaired mechanically.

In the following, the invention will be described in detail with reference to some application examples of the invention illustrated in the figures of the accompanying drawing, to which the invention is not limited.

Figure 1 shows a side view of a sack used in the method according to the invention.

Figures 2a and 2b show two alternative examples of cross-section of the sack.

Figure 3 shows a schematic diagram of the operation of the bagging device.

Figure 4 shows a 'kuhila' assembled from sacks to dry.

The sack 1 used in the method consists, for example, of a thin plastic film 2 and a plastic or fiberglass mesh 3. In order to prevent water flowing from the plastic down. It is also possible to use a structure in which the net is attached slightly inside the edges of the canopy, whereby the edge remains a nest over the net, as shown in Figure 2b.

25 The peat peat machine 5 travels in a prepared peat field and compresses pieces of peat from which it is lifted, which are led to the hopper 6 of the bagging device.

The sacks are sealed from a roll 7 of a flexible continuous strip by means of a sealing machine 30. Sealing can be performed either from a single sheet or by means of several sealing machines, only at this stage by combining the different materials of the sack.

While the sack blank is generated, the nozzle 9 feeds the peat into it 35 until the sack reaches a suitable length, the closing device 10 binds the ends of the sack closed. The tying is performed at two locations, so that each sack can be separated from the others without being unloaded. While both sealing and splicing technology are known per se from the packaging industry, these devices will not be explained in more detail.

5 Prefabricated sacks that are stacked in a vertical position can also be used.

When it is desired to dry the sacks in the form of a 'pile' shown in Fig. 4, two bagging machines are mounted in parallel on the sacking base.

In this case, the tying devices 10 cut the sacks into groups of two and the guide levers 11 turn the joints connecting the sacks towards each other. The ends of all four sacks are now aligned and the tying device 12 at the end of the shaft 12 connects them to each other, forming the structure shown in Figure 4. In this connection, the stem 12 lifts the lantern 15 into place in the swamp, after which the stalk 12 descends under the lantern and leaves it in place to dry. The short bag consisting of three sacks can be provided, for example, as a product of three parallel sacking lines.

20 When the dense plastic is on the surface of the sacks, the sacks are well protected from rain and if the length-to-thickness ratio of the sacks is appropriate, between 1-2 meters in length and 50-70 centimeters in thickness, the 'pile' also forms easily drying.

25 The mechanical harvesting of sacks from the gut can also be easily carried out by means of the actual conveyor placed under the pile, which lifts the pile into the transport trolley.

Also in storage, the bag used in the method offers certain advantages, as storage can be performed in an uncovered space, provided that care is taken to place the bags with the plastic film facing up.

The finished bagging also has an advantage in the sale of the product and further transportation.

The invention is, of course, not limited to the method and bag structure details described above by way of example only.

The following are claims within the scope of which the various details of the invention may vary within the scope of the inventive idea.

Claims (5)

62855 A method for drying and treating lump peat or the like, in which the lumps made by the lump peat machine are dried in a swamp, characterized in that the lump peat is collected directly from the machine (5) into sacks (1) of water-protective material (2) and air permeable material (3), and which sacks are placed in the bog to dry the peat with the water protective side up. A method according to claim 1, characterized in that the sacks are made of running strip or strips by seaming while guiding the lump peat into the sack (1) to be completed, whereby the resulting blank is made into sacks (1) by always stretching and tying . Method according to one of the preceding claims, characterized in that the sacks (1) are dried in 'piles' or similar heaps consisting of two or more sacks connected to each other at their upper ends, which stand on each other leaning upwards against the water-protective side of the sacks. 20 Sack for drying and possibly transporting, storing and other handling of peat, characterized in that one side of the sacks (1) is made of water-protective material (2) and the other part of air-permeable material (3), preferably perforated or net-like film material . Sack according to Claim 4, characterized in that the edge of the water-protective part (2) has a narrower trough (4) made of flexible material and / or a lip which prevents rainwater from flowing from the edge of the water-protective part (2) into the bagged piece. the peat.
