(54) SCRAP BARREL CONVEYOR

. I ..

The invention relates to industrial vehicles, namely conveyors used in factories for transporting fine metal chips.

Knuckle-scraper conveyors are known for transporting fine metal shavings comprising a drive, a chute and cOBispmaJpiHjTo along which there are reciprocating movements of the rod with scrapers. The forced rotation of the scrapers is carried out by interacting with copiers mounted on the walls of the gutter, or by means of additional: rod drives l.

However, the design of such conveyors

complex, and their loading bar is large.

Also known is a sucker scraper conveyor comprising a reciprocating drive, a groove, scrapers fixedly rotatable on a rod having stops cooperating with the scrapers, and a mechanism for turning the scrapers including control elements and levers rigidly connected with the scrapers.

When the rotation of the scrapers to enter them into the chip zone during the working stroke and the output at idle is performed by the interaction of the fingers of the scrapers with the copiers mounted on the side walls of the groove. The forced rotation of the scrapers is carried out from the copiers. The bar moves the chips in front of it, increasing the pushing force.

The use of a copier for scraper plots complicates the design of conveyors and makes the scraper turn unreliable because it depends on the accuracy of the installation of the copiers.

To unload the rod from the axial load and simplify the design of the conveyor, the levers are provided with straps, and the control elements are made in the form of a rope attached to the platform.

FIG. 1 shows the proposed conveyor, top view; in fig. 2. Section A-Af1№. one; see 3-section of fig, 1; in fig. 4 bb FIG. one.

The conveyor consists of a trench 1 and a rod 2 containing scrapers 3, rotated at a certain angle around its small pox until it stops on the rod. The axes 4 are rigidly mounted on the axis by a scraper. Perpevdvkulyarno to the axis of the rod 2 are fixed axes with rsatykam 5, which are installed in the guide holes of the guides b, located on both 6 boards; ). To the bars 7} connected to the levers 4 with the aid of an axle, the sleeves 8 are fastened with a rope 9. To securely attach the rope 8 to the bars 7, the rope is bent. the protrusion of the strap 7, At the end of the chute 1, there is a block 1O, between which the canal 9 goes around. The ends of the rope 9 are fixed on the drum, a reversible drive located at the beginning of the chute. The drum is rigidly fitted with an HfL single shaft with a gear that meshes with the rail, which is connected to the hydraulic cylinder. On the drum (according to its diameter) there are lays with a step equal to the step of moving the rod. During rotation, the stops interact with the limit switches, which instruct the wiper to change the direction of fluid flow into one or the other cavity of the hydraulic cylinder. Thus, the rope 9 is reciprocating. When the scrapers are located behind the block, the bar 11 serves as their hinge, which pivots the subsequent levers to the last lever that receives the turn from the rope 9 t The conveyor operates as follows. When you turn on the conveyor rope 9, mounted on the reversing drive drum, located at the beginning of the chute 1 and the envelope unit Yu at the end of the chute, receives a reciprocating displaced. When the drive drum is rotated clockwise, the rope 9 rotates the levers 4 and, accordingly, the scrapers 3 through the slats 7. At the initial moment, the rope 9 rotates only the scrapers 3, since their axes freely rotate in the bushings of the rod. Turning, the scrapers enter the material being transported. When the scrapers 3 come into contact with the stops of the 12 bars, the bar 2 will begin to move forward and move with the scrapers 3. shavings forward. At the beginning of the return stroke, the scrapers 3 rotate around a Jew axis; exit from chip area. When the scrapers 3 rest against the rod base, the rod also moves. Thus, at the beginning of the forward and reverse turns of the rope 9, the rod 2 does not; re-, interferes, but only turns on the n, ektory angle to the stops in the scrapers 3. When the scrapers 3 come into contact with the stops 12, the feet 1 and 2 the bar also moves. Then loop 1 repeats. The exclusion of copiers from the proposed conveyor simplifies the design and reduces the labor intensity of its manufacture. Since there is no need to make copiers and assemble them; reliability of work is increased, because the scraper is rotated directly from the traction organ-rope, which first increases them and then moves the barbell. The entire load on the movement of chips is perceived by the ropes, and not by the rod, which makes it possible to reduce the cross-section and the shaft of the bone. F o rm a l vobra shade A sucker scraper conveyor containing a reciprocating drive, a chute, scrapers fixed with the possibility of turning on a rod having stops interacting with the scrapers, and a mechanism for turning the scrapers, including control elements and the levers rigidly connected to the scrapers, distinguished by the fact that, in order to unload the shaft from the axial load and simplify the design, the levers are provided with slats, and the controls are made in the form of a rope fixed.
