Description

BACKGROUND OF THE INVENTION The invention relates to a flotation harvester for sorting and rafting logs into bundles using sorting and rafting machines arranged in a checkerboard pattern.

A distinctive feature of the floating combine being described is that in each case the drive rollers (dr) are used on each of the males, which act on the flooded logs from above to force them to move.

For sorting logs on the go, a lever and rake with a scale are used, installed at the beginning of the logs entering the machine.

The flooding of the logs and the formation of the beam is carried out by means of a transverse elevator and a working bridge with racks of a concave shape fixed on it.

With the help of such a combine can be sorted into twelve varieties and rafts on raid produced from logs. FIG. shows a diagram of the location of sorting and rafting machines in the combine; in fig. 2-plan of sorting and rafting machine; in fig. 3-cross-section of the machine; in fig. 4 shows an arrangement of drive rollers for sinking logs on the first sorting machine; in fig. 5-scheme of log thickness gauge device.

The floating harvester consists of twelve sorting-raft masks / arranged in a staggered manner on both sides of the fairway, along which the logs are moved endlessly from each other, forcibly moved by the driven rollers 2. The logs are fed from zapann 3 into the combine's harbor.

. Each sorting-rafting machine has two cylindrical canopies connected between itself by three I-beams 4. A moving bridge 5 with a capacity of two 6-inch electric winches moves with two middle beams. By both

stv.r.on-m of the movable bridge fortified rack 7 concave shape, case 1; achie, - dd () - logs.

 On the side opposite to the movement of the logs, the I-beam 8 is reinforced, made in the form of a purse with a net and preventing the logs from moving them forward as they flow.

The forced movement of logs along the channel of the combine is carried out by rollers 2 ,; The wheels are driven through a gearbox 9 by an electric motor. Seven two-three drive rollers with pinches are installed on the machine. And four idle rollers without pins that support the logs during the whole time of their movement in the flooded state. All seven rollers 2 are mounted on two channels, which can be raised and lowered as needed. On the first machine, which receives logs from the pool into the fairway of the combine, additional five rollers are installed, which flood the logs coming from the pool 3.

The dumping of logs into a purse (sorting) is performed by a transverse elevator by means of hooks 10, planted on two chains of Gall -,;. Gall chains are driven by motor II. Two sprockets 12 are mounted on the ends of the gearbox // shaft, along which the Gal.sh chain with hooks moves. Guides to the Gall chain are the rollers 13, which sit on a frame welded to noHTonv.

A tool for sorting logs is installed on each sorting and rafting machine at the beginning of log entry into the fairway of this machine. On the M axis, the device is fixedly mounted on the machine channels, the GD arm 15 is mounted, at one end of the blade 16, which all the time at 1 is connected to the floating log with the weight-77 mounted on the other end of the lever 15. On the blade 16 The pointer 18 slides freely towards the guides 19. On the pointer 18 there is an arrow indicating on the scale 20 the thickness of the log located between the bukha 21 and the shovel 16.

The worker, STANDING at the fairway of the sorting-cn / bar machine, monitors on the scale 20 the log thickness indicator arrow and, if the log does not correspond to the thickness that this machine sorts, the worker presses the clamp pedal with a foot to stop the floating log. and at the same time presses the button, including the 1. transverse elevator into operation to flood the log into the water with hooks 10 mounted on the Gall chain, to drop the 6peiHia into the purse of the machine. Having dropped the log, the hooks automatically stop above the next floating logs. In order to absorb the inerchs of the floating log, there are clamps that work together with drop hooks.

The beam formation of logs, interconnected by the transverse elevator of the rafting machine, is carried out by a movable bridge 5 with racks bent in the shape of a pouch fixed on both sides. two-drum winch 6, mounted on a nodvizhniy bridge. On each drum of the winch is wound a cable, the ends of which are fixed on pontoons. Rotating, the drums of the winch pull the cables and force the bridge with the stands to move. Due to this, the logs in the purse are compressed (formed) into a bundle between the pillars fixed on the pontoon and the pillars 7 of the movable bridge.

The tie of the formed beam of logs is produced by two workers manually with wire or chains.

The withdrawal of the finished beam from the purse to the raid is carried out. turntable with boom 22, driven by an electric motor. The advantage of the proposed combine is to mechanize the sorting of logs, which causes a reduction in the time spent on producing sorting and reducing the required area of water for raft forests.
