KLAPIPROSESSORI

The invention relates to a valve processor of the type mentioned in the preamble of claim 1.

In practice, firewood is most often made by pruning felled trees and driving them to the county, where they are made into logs by a wide variety of methods.

10 The main disadvantages of the current production of logs are the multiple handling of the trees and the fact that the pruning of the branches and the feeding of the logs have to be done by hand. In the devices disclosed in patents 66137 and 78014, when attached to a tractor, the trees are fed from behind, preventing simultaneous use of the trailer, and since the trajectory of the moving splitting blade is circular in the transverse direction of the tree, they do not split the tree in a straight line.

The device according to the invention provides a decisive improvement in the above-mentioned drawbacks. To achieve this, the device according to the invention is characterized by what is set forth in the characterizing part of claim 1.

The main advantage of the invention is that the device has pruning and feeding devices, so that these heavy crafting steps do not have to be performed by manpower and that the trajectory of the splitting blade is substantially parallel to the longitudinal axis of the wood.

A preferred embodiment of the invention will now be described with reference to the accompanying drawings.

The blade processor comprises a sturdy frame 1 to which the tractor's three-point hitches 18, the feeder frame 2, the pruning device frame 3, the counterblade 9 and the bearing shaft 16 to which the axle wheel 11 is attached are mounted. to the axle wheel with a chain 12. The reciprocating movement of the feeder is effected by means of a drive arm 7 and a transmission rod 6. The body of the feeder is mounted inside the body 1 by bearings 15.

The stroke length of the feeder and at the same time the length of the platform is adjusted by changing the length of the operating arm in the usual way. The spring-loaded gripping blades 5 adhere to the wood during the feed movement and also the spring-loaded wood presser 8 prevents the wood 15 from moving backwards during the return movement of the feeder. The pruning of the branches is performed by the pruning blades 4 in a manner known from the harvester. The splitting / cutting ax 10 is attached to the ax wheel 11 according to Fig. 1. Since, viewed from above, the axis of the ax wheel is perpendicular to the longitudinal axis of the tree, the ax rotates parallel to the longitudinal axis of the tree 20, always splitting the tree perpendicularly and regardless of the size of the tree from the center or about the middle. The ax blade 10 splits and cuts the wood against the lower blade 9 during the return movement of the feeder. Seen from the rear of the device, the cutting surfaces of the ax and the counterblade are in the shape of a circular arc 25, with the ax having a wedge shape and a V-hole shape in the counterblade when viewed from the direction of wood feeding. In the figures, reference numeral 17 is a chain tensioner and 20 are support legs. In addition, a trailer and a tree conveyor are installed in the conventional manner, which automatically transfers the pallets to the trailer.

The production of firewood with the device according to the invention takes place J in such a way that the device connected to the tractor with its trailers and conveyor is driven in the vicinity of the trees to be chopped, lowered to its support legs and started. The footswitch opens 35 pruning blades and the base of the tree is placed in the feeder. During the feeding movement of the feeder, the pruning blades remove the branches and during the return movement the ax splits and cuts the wood against the counterblades. The finished pallets are transferred by the conveyor to the trailer.

Claims (4)

A log processor comprising a body (1), a wood pulse feeder (3, 5), a rotating splitting blade (10) with fixed counter-blades (9) and rotating devices (11, 13, 14) and wherein the splitting blade (10) is adapted to rotate on its shaft (16) so as to meet the wood on the feed line at certain points to split its end and cut the split parts together with the fixed counterblades, characterized in that the plane of rotation of the splitting blade (10) is set on the feed line and the processor includes a pulse feeder (3, 5) a swivel pin (6) articulated to a drive arm (7) mounted on the shaft (16) of the splitting blade (10). Wood chip processor according to Claim 1, characterized in that the wood chip processor comprises pruning blades (4) arranged on the supply line. • «t Wood chipper according to Claim 1 or 2, characterized in that the splitting blade (10) is positioned relative to the operating arm (7) of the heart rate monitor (3, 5) so that the splitting takes place during the return movement of the heart rate monitor (3, 5). 4 95884 3 95884 When the machine is working on wood, the user takes the next frame for the machine. The frames can also be fed with a light timber loader mounted on the same tractor, which means that the logs are manufactured entirely mechanically. 5 The log processor can also be made into a trailer-mounted model for transporting trees, mainly in the county. In this case, the drive motor can be any suitable power device. It is clear that the various embodiments of the invention are not limited to the examples given above but may vary within the scope of the appended claims. 15 Valve processor according to one of the preceding claims 1 to 3, characterized in that the splitting and counter-blades (10, 9) are parallel to the circumference of rotation at their opposite surfaces.
