Abstract

The invention relates to devices for separating wood greens from branches and branches in a rotating drum and can be used in the forest industry. The purpose of the invention is to improve the quality of the separated greens and increase the service life. Each separator is made in the I w / Yf / f / f / f / rM I type of 3 spring-loaded corrugated disks 4 installed on the flexible core. For tightly adjoining the disks 4 and reliably pinching the separable green, a spring 5 is installed on one end of the flexible core 3 adjusting screw 6. Freely located separators 2, moving in a rotating drum together with knots and branches, are bent in all directions. At the same time adjacent discs capture them, hold and tear off green wood. This separator 2 has a long service life, because, due to its design, it does not perceive alternating and fast-changing loads, and also does not squeeze greens, which improves its quality. 6 Il. 4 To Guy Yu

The invention relates to devices for separating wood greens from branches and branches in a rotary drum and can be used in the lent industry.

The purpose of the invention is to increase the safety of the separated greenery and increase the service life.

Fig, 1 shows the green separator; fig 2 - section,. A-A in FIG. one; in fig. 3 - disk, side view; in fig. 4 - the process of separation of greenery from the branches and branches; Fig. 5 illustrates the process of operation of the separators in a rotating drum; in fig. 6 is a section BB in FIG. five.

The working part of the device for separating the green includes separators 2, which are freely located in the rotating drum 1. Each separator 2 is designed as 3 spring-loaded corrugated disks 4 mounted on a flexible core.

. To tightly adjoin the discs 4 and securely pinch the separable green at one end of the flexible core 3, a spring 5 is installed with an adjusting screw 6.

The disks 4 can be made of stamped metal plates 7, coated on both sides with a layer of rubber 8.

To improve adhesion of the rubber layer 8 to the metal plate 7, the latter is made with holes 9 and a rough surface. The disks 4 in the central part have convex tides 10 and an opening 11 for installing them on the flexible core 3. The convex tides 10 ensure that, when the working bodies are bent, a smooth rolling of the central part of the disks 4 relative to each other, practically without increasing the total length of the flexible core 3.

In front of the drum 1 there is a loading mechanism 12, and behind it is a unloading mechanism 13. The unloading mechanism 13 is combined with a device for separating the separators from the treated branches and branches and consists of a gate 14 and a roller table 15. The roll table 15 has rollers 16, inside which electromagnets 17 are mounted, to which voltage is supplied through current-collecting brushes 18 (not shown ) from split rings 19 (not shown). Under each roller 16 there are scrapers 20. Under the roller table 15 there is a sieve 21, a conveyor 22 and a green storage 23. A conveyor 24 is mounted between the unloading mechanism 13 and the loading mechanism 12 to return the separators 2 to the rotating drum 1.

The working device of the device operates as follows. Pre-crushed 30-70 cm knots into pieces and the branches are fed into the rotating drum 1 by means of the loading mechanism 12 and mixed together with the separators 2. The branches and the branches act on different parts of the separators 2 and bend them . As a result of the bending of the separators 2 in zone A (FIG. 4}, discs 4 and the greens penetrate between them. At the same time, compression and retention of the greens between the disks 4 from the diamonds 4 and separation from the branches occur) from the diametrically opposite side and branches. The zones of divergence and compression are constantly changing both along the length of the separators 2 and in its transverse section. In the process of separating the greenery, the entire surface of the separators 2, each of which is occupied by sets of adjacent disks 4, is captured, held and The process of separation of greens occurs due to the difference in speed between the separators 2, which retain greens, and the branches with branches, while stirring them in the rotating drum 1, as a result, tensile forces occur between the separators and the branches, which cause exceeding forces adhesion of green with wood.

With this, a large amount of greenery comes off simultaneously. The treated branches and branches, together with the separated greens and elements 2, are removed from the rotating drum 1 through the gate 14 of the mechanism 13 for unloading onto the roller table 15, where they are separated. On the roller table 15, the greens wake up between the rollers 16 and, sifting through the sieve 21, enter the green storage 23, and the separating elements 2 are attracted to the rollers 16 by electromagnets 17 and removed from them by scrapers 20. Rolled along the sieve 21 and the conveyor 11} the separating elements 2 fall onto the conveyor 24 to return them to the rotating drum 1.
