Method and wagon for handling logging residue

The invention relates to a method for the treatment of logging residue using a load carriage, which is preferably intended to be towed by a pulling device such as a vehicle, a work machine or the like. The wagon has at least a container having a bottom, side and end walls, engagement means at a first end of the wagon, such as a drawbar 10 or the like for engaging force on the towing device, and preferably at least a movement means for moving the wagon such as wheels rolls or the like, for transporting the logging residue by a truck for transportation by road or similarly to a point of use, reception or the like, which is known per se.

Today, the handling of logging residues is carried out, for example, by chopping logging residues on site, and then collecting them for transport to a pick-up point. Ex. in terminal production, the logging residue is dried over the summer to improve its calorific value. Thereafter, it is also possible to further store conventionally chopped chips.

For this type of so-called. there are several problems with roadside chipping, one of the most important of which is the waiting time for the forty-one forks: firstly, the chopper waits for the load-discharging truck, and respectively the truck waits for the chopper to load. As a result, the current situation always results in underutilization and downtime of the fleet, which significantly reduces labor productivity and further increases the selling price of wood chips from logging residues. In addition, chipping off-site requires continuous recycling of the 2 104318 hackers and their users from one work station to another.

On the other hand, the transport of logging residue or timber in the compressed state 5 is known per se from the solutions disclosed in e.g. FI 862326, SE 379315 and US 3,008,731. The solution presented in the first of the foregoing is intended in particular for low compaction and bonding of subtree, impartial chips and tailings, which, however, cannot be practically accomplished, particularly in the case of logging residues, since pallets of this type first have open ends. On the other hand pallet means 15 consists of a square one side of the vertical extension of the telescopic portion, which is bent 90 ° to a horizontal plane of the upper panel the latter which is pivotable about a vertical axis on the square of the load and the load to and from the top end of the gripping member. Similarly, 20 of the second side of the vertical square of the telescoping section away from a counterpart to which the above. Gripping member is lockable. Thus, the actual compression effect provided by the solution in question is very nominal due to the way of sealing and only operates at the stage when the pallet is fully assembled. Thus, the present invention. The solution device is, as its name implies, only for truss binding.

On the other hand, Swedish Announcement Publication No. 379315 discloses a solution of a different construction than the above, in which the loading device is formed by mutually movable wall structures. The operation of this solution and the structures it requires are disproportionately complicated and bulky, making it practically impossible to use this solution, especially because of the bogies on uneven forest trailers and therefore also on forest loading. In addition to that.

3 With the 104318 solution, loading is performed from the top of the unit's own grapple loader, so on the other hand, the loading cannot be performed with the unit's own drawbar or tractor-5 loader.

Further, the solution disclosed in US 3,008,731 includes an arrangement specifically designed for the transportation of forest wood, whereby the loaded 10 timber can be compressed for transportation. The solution disclosed in this patent is by no means capable of assembling and transporting logging residue in particular.

The process of the present invention is intended to provide a decisive improvement on the above problems and thereby substantially improve the state of the art. To accomplish this purpose, the method according to the invention is essentially characterized in that the logging residue is assembled into a load carriage, the first members of the press members being compressed by the first members of the pressing members moving the wall of the wagon, preferably the sidewalls, in a substantially transverse direction. 1 2 3 4 5 6

The main advantages 2 of the process according to the invention are the simplicity and reliability 4 of its operating principle and of the constructions applicable thereto. The invention makes it possible to significantly improve the economical handling of logging residue 6, which also allows the final product, e.g.

the cost of producing chips for combustion can be significantly reduced. The method of the invention improves. work efficiency as well as 4,104,318 productivity remain crucial, as it avoids, on the one hand, normal idle and waiting times, and, on the other hand, reduces equipment and personnel in the terrain. As a result, the method of the invention thus also significantly improves the utilization rate of the machine base.

Advantageous embodiments of the method are set forth in the dependent claims.

The invention also relates to a freight wagon for applying the method. The loading wagon is described in more detail in the preamble of the independent claim thereon. The predominantly characteristic features of the freight wagon are shown in the characterizing part of the corresponding claim.

The most important advantages of the cargo trolley according to the invention are its simplicity in operation and construction and its reliability. The loading crane according to the invention makes it possible to rationalize the handling of the logging residue, since at the same time it is compressed when the logging residue is loaded onto the load carriage, thus providing sufficient weight for the logging residue transported in the cargo container 25. The loading wagon of the invention also eliminates the problems associated with current working practices in that it eliminates the need to transport harvesters to work stations to carry out chopping in the terrain, but instead allows logging residues to be assembled as such in the loading wagon. The load trolley according to the invention thus • significantly improves the productivity and efficiency of the work, which also allows a significant reduction in the cost of manufacturing the final product made from the logging residue, e.g.

S 104318

In the following description, the invention will be illustrated in detail with reference to the accompanying drawings, in which: low cost structural solution.

The present invention relates to a method for treating logging residue using a load carriage which is preferably intended to be towed by a pulling device such as a vehicle, a working machine or the like. The truck has a container 4 having at least a base 1, side 2 and end walls 3, coupling means 5 substantially at the first end I of the load carriage, such as a drawbar or the like, for releasing force thereon, and preferably at least at one end II. means 6, such as wheels, rollers, or the like, for transporting the logging residue by means of a freight wagon for road transport or, respectively, to a point of use, a reception point or the like, known per se. The logging residue is assembled in a truck where the logging residue is compressed by the first members X1 of the pressing members on one hand tilting w on one or more load wall walls, preferably 35 sidewalls 2, 2 substantially in the transverse direction p.

The compaction movements of the above type are preferably carried out in the forest during the loading step e.g.

when moving from one tree to another. The required amount of compaction movements is made to achieve sufficient compaction, in which connection it is possible to add logging residue through the open top of the container 10 by means of a loader. For loading or on the other hand, the load can also be discharged using, for example, a loader equipped with a grab, for example placed on the roof of a tractor or on the drawbar of a load wagon.

The cargo trolley according to the invention is particularly developed in that it comprises a conventional container structure 4; 1, 2, 3, in addition to the drawbar 5 and the wheels 6, press members X to compress the logging load 20 loaded thereon in the same connection as the load is carried out. In a preferred embodiment, preferably the pressurized, electrically operated and / or corresponding press members X are arranged substantially integrally, e.g. in connection with two opposed side walls 2 of the load carriage 25. Thus, firstly, the first members X1 of the clamping members are provided on the body of the load carriage for moving the side walls 2 about a substantially horizontal axis by tilting w. In the drawings, the actual actuators for moving the walls 30, e.g., hydraulic cylinders or the like, are not shown in more detail.

On the other hand, the load carriage is also provided with second members X2 of crushing means for compressing the logging residue 35 by moving the sidewalls 2 substantially in the transverse direction p. In this case, for example, hydraulic cylinders are connected to the bottom of the load carriage, which widen and narrow the bottom of the tank 2, for example by means of telescopic designs. In this connection, the side walls 2 and the end walls 3 are naturally connected to each other by expansion joints and, if necessary, coated with braided solutions or respectively to provide sufficient sealing.

In a further preferred embodiment, the top of the load carriage is left open, whereby the load carriage is loaded through it. On the other hand, the side walls 2 are further arranged at their upper part 2 'to be bent inside the load carriage. In this case, an effective sealing of the load is achieved while pressing it downwards.

Referring further to the principle shown in Fig. 3, the walls of the load carriage, and in particular the Movable Side Walls 2, are arranged in particular to optimize their weight / stiffness ratio against bending in a stiffened structure, preferably by profiled sheet metal or the like. Reference L 20 illustrates the total lateral movement of the sidewall in the transverse direction.

It is to be understood that the invention is not limited to the embodiments described or described above, but that it can be very substantially modified within the scope of the basic idea of the invention. In this case, firstly, it is possible to construct the load wagon, e.g. It is, of course, also possible to use completely separate press devices in connection with the load opening, in which case, however, the loading must be carried out in a so-called. annosperiaat-basis. Particularly in this type of solution, it may be advantageous to provide, e.g. On the other hand, the embodiments described above can also be provided with a roof opening for loading / unloading to close the load carriage 8 104318 especially during transport. It is also possible to arrange one or both end walls of the container to be movable, e.g., as shown, but requiring more complicated constructions than shown.
