Abstract

The invention relates to conveyor transport and improves the reliability of operation of the device during the steeply inclined transportation of windrowed chips. The ascending branches of the lower and upper scraper conveyors (K) 1 and 2 are located steeply inclined and parallel to each other one above the other and are supported on frames 3 and 4 connected to each other by means of pairs of parallel-installed racks 15. The ends of the racks 15 are hinged to the frames 3 and 4. On the latter, there are installed one-type drive mechanisms 5 with drive rotary elements (PE) 6 in the form of asterisks and tension mechanisms with tension PE 7 in the form of tension stars. The flexible body of each K 1 and 2 is made in the form of two pulling chains 8 endlessly closed on PE 6 and 7 with scrapers 9 painted between them. At the same time K 2 has main and additional PE 7. The additional tension device of additional PE 7 is made as two double-arm levers (P) 10, one shoulders of which are connected to frame 4 by means of rollers 11 installed in its guides, and moved into them by means of hydraulic cylinders 12, others with additional PE 7. The axes of rotation P 10 are hinged to frame 4 by means of hydraulic cylinders 13 with the possibility Strongly rotation in a vertical plane. Between the main and additional PE 7, an 18 K 2 feeding branch is placed. Due to the directional movement of the ascending branches K 1 and 2, the chips in the process of gripping, pressing and transporting to the unloading zone do not experience reverse movements. 2 Il.

The flexible organ of each K 1 and 2 is made in the form of two two centrally driven towers 8 which are infinitely closed on PZ 6 and 7 with scrapers fixed between them. At the same time, K 2 has a main and an additional PE 7. The additional tension device 7 of the additional PE 7 is made in the form of two double-arm levers (P) -10, one of which is connected to the frame k of the end of the invention. - devices for gripping, subpressing ICOBKH and uniform supply of wedge chips for crushing and can be used in enterprises of secondary ferrous and nonferrous metallurgy.

The purpose of the invention is to increase the reliability of the device during the steep transportation of wedge-shaped chips.

FIG. 1 shows a transport device, side view; FIG. 2 shows section A-A in FIG. one,

The transport device contains lower and upper scraper conveyors 1 and 2P whose ascending branches are located parallel one above the other and are placed at an angle of 30-60 ° to the horizontal. Both conveyors 1 and 2 have frames 3 and 4, on which are mounted the same type of driving mechanisms 5 WITH DRIVE ROTARY ELEMENTS made in the form of 6 y stars and tension mechanisms with tensioning turning elements made in the form of tension sprockets 7 The flexible organ of each conveyor 1 and 2 is made up of two traction chains 8, infinitely closed on sprockets 6 and 7, with scrapers 9 fixed between them and resting on the frames of the conveyors. The upper conveyor 2 has a main and an additional pair of tension sprockets 7 Additional The tensioning device of a pair of additional tensioning sprockets 7 is made in the form of two double-arm levers 10, an extension of the rollers 11 installed in its guides, and moved into them by means of hydraulic cylinders 12, others with additional PE 7. The axes of rotation P 10 are hinged to the frame C by means of hydraulic cylinders 13 can be rotated in a vertical plane. Between the main and

With additional PE 7, an 18 K 2 feed branch is placed. Due to the directional movement of the ascending K 1 and 2 branches in the process of picking up, pressing and transporting

ij unloading zone does not experience reverse movements. 2 Il.

Their shoulders are connected to the frame 4 by means of rollers 1 1 installed in its guides with the possibility of reciprocating movement provided by hydraulic cylinders 12 whose rods are connected to rollers 11, and the other arms of levers 10 are connected to a pair of additional tensioning sprockets 7. Moreover, the axis of rotation of the levers 10 pivotally connected to the frame C by means of hydraulic cylinders 13 with the possibility of rotation in the vertical plane. The frame 3 of the lower conveyor 1 is rigidly connected to the support frame 14, which is made in the form of a frame of a welded structure attached to the foundation,

The frames 3 and C of both conveyors 1 and 2 are pivotally interconnected in pairs of parallel-mounted racks 15 with the possibility of changing the distance between the frames of the conveyors by means of a mechanism for moving and fixing the frames, made in the form of hydraulic cylinders 16 pivotally connected by rods with a pair of racks 15 and cylinders with frame 3 conveyor 1.

The lower scraper conveyor 1 is installed in such a way that its rising branch in the lower part is located in the receiving tray 17 below the lower part of the rising branch of the conveyor 2, and the upper part of the rising branch of the lower conveyor 1 is located below the upper part of the rising branch of the conveyor 2, which it contributes to the optimal capture of chips from the receiving chute 17 and unloading the ascending arms. The upper KOH conveyor 2 has a feeding branch 18 located between its main and additional tensioning sprockets 7. The ascending branches of the conveyors 1 and 2 are doubled in one direction with the same speed. The angle of inclination of the ascending arms of the conveyors is determined by the installation height of the crusher (not shown) to which the chips are fed. In this case, the greater the angle of inclination of the ascending arms of the conveyors to the horizontal, the lower the productivity of the conveying device.

The device works as follows.

The windrowed chip enters the receiving chute 17 where it is caught by the scrapers of the feeding branch 18 of the conveyor 2 and is fed to the rising branches of the conveyors 1 and 2. between which it is pressed and uniformly applied in a uniform layer for crushing. When hit together with shavings of uncrushed objects, they are also drawn in with the shavings and are fed for crushing. As the poppy chips are unloaded from the receiving tray 17, the feeding branch 18 of the upper conveyor 2 is lowered by means of hydraulic cylinders 12 and 13, providing a continuous supply of chips to the ascending branches. To increase the supply of chips for crushing, increase the distance between the frames of the lower 1 and upper 2 scraper conveyors using hydraulic cylinders 16.

Thus, the chips in the process of gripping, pressing and transporting to the unloading zone do not experience reverse movements due to the directional movement of the ascending branches of both conveyors 1 and 2. This leads to stabilization of the chip supply process, reduction of overloads and shutdowns of the device and, consequently, increase its reliability.

The main advantages of the device are continuous high-speed movement of chips in a single layer, ease of loading and unloading, unloading transportation along a difficult route, safety

material, the opportunity for a great height with water.
