Description

The invention relates to a device for sorting logs on water that can be installed on pesospawan raids. A device for sorting logs on water, containing a floating base in the form of bridge-connected pontoons, on which drive and tension stations with branches of plate chains located between them, and a drive jl, are known, is known. A disadvantage of the known device lies in its low productivity. The aim of the invention is to improve the performance of the device. This is achieved by the fact that in the proposed device, double racks are attached to the branches of the chain chains, pa angled 1O-15 to these branches and bearing of the box section cross section, inside of which a floating element is located, for example foam plastic. On fkg. I shows the device dp traysprgirovkp logs; in fig. 2 longitudinal section-device; in fig. 3 crappen traverse to the foil; in fig. 4 a section in FIG. 3; in fig. 5 is a diagram of a stagger of a log (I is the thrust of the pusher in a “similar position; And the thrust of the pusher is in the final position); in fig. 6 Uzev paired pusher. The device contains metal pontoons 1, which form a sorting stepwise narrowing corridor 2. In the corridor pontoons there are side gates 3 (overlapped with flooring) and sorting yards 4. In the side gates there are drum boosters 5 installed above the water. Over each side gate (on the beams there are overlapping gates - above) a paired driver 6 is installed at an angle of 4S to the axis of the device. The paired gidrokolkatyp has a control unit, which is located above the water of the corridor. The device contains a sorting

conveyor 7, drive and tension stations 8 and 9, mounted on transverse bogs. The drive station has two leading sprockets 1O, an electric motor with a gearbox. Tension station has two driven stars II. The drive and driven sprockets are interconnected by lamellar chains 12. Floating crossbars 14 are attached to the lamellar chains of the conveyor belt on double racks 13. Dual racks are arranged to ensure the transfer of the central load from the cross bars to the tsem, since one chain has two plates, therefore it is necessary one rack () {) heat to the right plate of the chain, another to the left, for which welding two corners 15 are attached to the cheeks (plates) of the chain, and each end of the rack is attached to the two bolts on the two bolts. enioy) are welded to the yoke 16 traverses. Each strut of the traverse to the chain of the tort sportor is not fixed at an angle of 90, and eii sold an angle of attack of -15 ° along the direction of diving. The angle of attack must be trapped for traversing the logs under the traverse, as it can move along with the log, it can (bend backwards).

Consequently, the racks for the trailers are not on the pontoons, but on the wheels of the sorting conveyor. Traverses have high buoyancy and reliably support the lower branches (chains) of the sorting conveyor under water: at a required height, ensuring that the maximum diameter of sorted logs passes under the chains.

Usually, the distance between the axes of the leading and driven sprockets of the sorting conveyor in production conditions is taken from 5O to 15O-2OO m. Therefore, the lower branches of the chains have a large sag and sink in the water. If the chains, lower branches of the sorting conveyor do not rise above the water surface, then it is impossible to direct the log across the conveyor and sort it. The upper branches of the conveyor chains are supported by the rollers 17 (Fig. 2). From the drive shaft with leading sprockets 10 is driven into rotational

motion. The lower chains of the sorting conveyor with grass 1x; are moved from left to right. Under t taverns served, moving through the water, the log 18 manually

or a special piece-feeding mechanism 19. Next, the log 18 is driven by a crosspiece 14 through the water along the sorting corridor 2. At the same time, the operator presses a button and leads to

the action is the pump of the hydraulic system, then the operator presses the button of the side gate 20 (where you need to sort the log). This gives the order for pushing the log to the hydraulic ram 6.

As soon as the traverse brought the log 18 to the hydraulic pulley 6, the final switch comes in contact with the traverse and the hydraulic pulley 6 it starts moving and the CBomvi with the stop 21 contacts the end of the log 18 and feeds its front end under the pin of the rotating drum of the accelerator at the gate under the flooring, which, interacting with the moving head plate 14, leads it out of the sorting corridor through a side gate into the sorting yard. The process then repeats. The operator pushes the other buttons and guides the logs to other sorting yards.
