Description

logs and, if necessary, perform the appropriate separation of db-filled logs at the following lifting means. Thus, the conveyor in the end position transmits only one log at a time, for further processing.

The goal is achieved by the fact that the length of the lifting element is much shorter than the length of the grip located between the two adjacent lifting elements. The lifting element can be made with a narrow ridge, placed along the axis of the conveyor, and the comb of the lifting element can be made in the form of a sharp edge. The hooks, located one after another, can be connected by bridges, placed on D lift 11 “1 and elements.

FIG. .1 schematically shows the proposed device; in fig. 2 - part of the conveyor, top view in vertical section (close-up); in fig. 3 is the same; the section along A-A in FIG. 2; in fig. 4 and 5 - the device in the process of work, a schematic side view; in fig. 6 - the device, a perspective view with a vertical section of the part of the conveyor ..- :.

A device for separating logs from a pile and separating them consists of a conveyor 1 and a supporting surface 2, which goes up in the direction of movement (arrow B) of the conveyor. Conveyor 1 includes four endless chains 3 that slide in guide grooves 4 formed in the support surface. The conveyor chains are equipped with gripping means 5, which are set up to form transverse rows captured by their elements, and these rows are arranged with an interval between them in the direction of motion. .

Lifting means 6 have a sharp ridge and a wedge-shaped tip and are mounted on a support surface between the conveyor chains. The lifting means are arranged in a similar manner to form transverse rows of lifting elements, the rows being stirred at a distance between themselves in the direction of travel.

A discharge conveyor 7 is installed at the inlet end of the conveyor 1, onto which a pile 8 is placed. At the outlet end of the cross conveyor 1 there is a longitudinal conveyor 9, by means of which the separated and separated logs are exported for further processing. As shown in FIG. .1, it is possible to install several conveyors subsequently, which were a separation operation (point 1 a). Transfer plane 10, up. A photocell, for example, can be located between the conveyors moving the logs 11 and 12.

The device works as follows.

When the logs are separated from the pile 8, one or more logs 11 and 12 (see Fig. 1-4) Punch one time on the transverse conveyor 1. The gripping means carry the logs: forward in the direction of arrow B.

When logs appear at the first lifting means, they rise; if the gripping means carry more than one log at a time, then the additional log or logs (log I in Fig. 4) rise so far relative to the upper edges of the gripping means that the logs roll back over the gripping means to the subsequent gripping means, while the remaining log (log 12 in fig. 4) is still transmitted by exciting means forward. Several rows of lifting means are sequentially mounted in the direction of motion (as shown in Fig. 2) in order to ensure that all additional logs are removed from each row of exciting means.

Medium - transverse extent B of lifting means 6 is considerably less than the average transverse extent G of exciting means 5. Thus, under unfavorable conditions it is soiled, snow and ice

cannot accumulate in front of lifting means. The lifting means form wedge-shaped profiles in the direction of motion (as shown in Fig. 3) and have a narrow or sharp ridge and a wedge-shaped top. Consequently, lifting means

They have a very slight residual effect on dirt and ice. Wide, exciting, efficiently keep the bearing surface 2 clean of dirt.

Lifting means in the simplest form can be formed by vertical wedge-shaped plazstinkami or similar manner. Even if these gripping means are used, which are located at a distance between themselves, these gripping means in each row of MOJKHO should be connected into one-piece device by bridges passing over the lifting means (as shown by dotted lines in Fig. 3) .-. .-: .-- Invention Formula
