Description

one

The invention relates to a device for the lumbering of timber and can be used in the forest industry 4-. ;

A well-known installation for cutting timber logging includes an anism of piecewise transverse output of timber, equipped with buffers, feed and retraction of transverse conveyors, a sawing mechanism and a conveyor of longitudinal transfer of timber to the opening 1. Its disadvantage is low productivity.

The purpose of the invention is to increase plant performance.

For this, the plant is equipped with an additional at least one more parallel-set longitudinal feed conveyor, the distance between the axes of the longitudinal conveyors being equal to the buffer level of the streets; go, feed and discharge transverse conveyors.

FIG. 1 shows the proposed plant for timber hacking, a plan; in fig. 2 - section A-A. 1 in FIG. 3 - section BB of FIG. 1. Installing WAYS FROM Mechanism 1 of a single issue of timber, a transverse buffer conveyor 2 with a drive shaft 3 and a cross feed conveyor 4 with a drive shaft 5. mechanism 7, consisting (in this case) of two circular saws on a turning frame, and a mechanism for the longitudinal supply of Timber for cutting. The latter consists of p yes

5 (in this case, four) longitudinal conveyors 8 with V-shaped cross-pieces 9, arranged parallel to each other and adjacent to the lateral side of the transverse conveyor 4.

0 The distance between the longitudinal conveyors 8 |; is equal to the step of placing the stops 6 on the traction organs of the transverse buffer 2 and feeding the 4 conveyors.

five

On both sides of the longitudinal conveyors 8 of the mechanism for feeding timber to the cutting on the frame, there are mounted supporting partitions 10 of the trapezoidal profile.

With allowance to move the timber lugs in the transverse direction through the longitudinal conveyors 8. The height of the separation slides 10 is less than the height of the pushers, which ;;; allows them to move the timber through the Torks. On the sides of the conveyors 8, the L-shaped levers 11, equipped with pressure rollers 12, are snuggled. The levers are equipped with individual drives, and the hydraulic cylinders rotate them {not shown). {Reverse transverse conveyor 13 is included in the plant design. with lugs 14, placed on traction, organs with equal to the pitch of the lugs of the conveyor 4, From both ends of the conveyor belt, there are conveyor-forest collectors 15, transferring the assortments to the storage pockets 16. One karma is accumulated a porter logger is also installed at the end of the cross feed conveyor 4. Between the traction bodies of the grating conveyor 13, coaxially divided slides 10, guide 17 triangular profiles are mounted on the frame, which prevent the stop torTsbv of the cut-off logs from resting against the stops 14. Megapods 1TsYM Conveyor 13 and Pillow Mechanochemum 7 have a pyoshadké with opening curtains 18, KoTojibiix can get into the hatches of the KoTojibiix, and then take out the longitudinal outboard conveyor 19. It works a timber for discloses zhovki .om follows. Tranolort package of whips with a crane equipped with a grab is inserted into the mechanism of piece-wrench output 1 so that the left part of the hubs protrudes from the right side of the mechanism of the piece-worm issue (in Fig. 1 is shown a linegay), they are quenched. drive of the piece-by-piece mechanism, starting one-by-one to issue hooks to the buffer conveyor, 2, which operates cyclically (synchronously with the output of the logs) until all its working checks are filled (there are four in this case). During the filling of the fourth cell, the simultaneous movement of 6y fern 6 2 and 4 transport vehicles by four steps at once takes place, so that the Tombs. parts of the logs are simultaneously placed over the cross-pieces 9 of the longitudinal conveyors 8. The operator turns on the drive of the turning levers 11 with the rollers 12, and later presses the butt part to the cross-pieces 9. After evaluating the c4BO ctBO, the operator sets an individual cutting program for each of them, then includes the drive of the conveyors 8, which, in accordance with the order system, move the X. sheets to a predetermined distance. Depending on the quality of the whip, the operator can cut it. Immediately or propel farther for otkomlevki. The opening of the whips supplied by the conveyor 8. is carried out by the saw mechanism 7. Pick-up and cut, the whip through the opening curtains 18 fall on the outboard longitudinal conveyor 19 and move them beyond the limits of the installation. In what capacity. H. Sawed assortments are placed between the stops 14 of the reversible removal of the conveyor 13 conveyors, which pushes the assortments in the direction of a storage pocket in four steps, so that subsequent assortments can be placed on the removal conveyor. From the retraction conveyor 13, the assortments are fed to the transporters-forestmasters 15 and further into the storage pockets. Conveyors 15 play the role of a buffer device at full load of pocket-accumulators or at the moment when the finished package is removed. from HctKoWHTenH. After digging hyyStov into assortments of the vertex USETiuTtitCTOB by reversing the transport, ditch 8 is sent back to the cells of the feeding conveyor 4, which moves them to an adjacent storage pocket 16. The machine includes a mechanism; in a boxed transverse delivery of a timber ump, equipped with a stop buffer, feed and discharge transverse conveyors, a saw mechanism and a conveyor of the longitudinal feed of trees for cutting, so that In order to increase productivity, the plant is additionally equipped with at least one more longitudinal conveyor installed parallel to it. feed, and the distance between the axes of the longitudinal conveyors is equal to the stops of the buffer, feed and discharge transverse conveyors. g Source and information, obtained by VU attention at examination 1.
