Description

(54) CARGO TRIPPER

The invention relates to the timber and woodworking industry and can be used, for example, for dumping b}, even, bryoz, boards from a longitudinal conveyor to a hopper when sorting them.

A cargo dumper is known, which includes, horizontally, a pusher; 1 taln () th action, a ball of nrno fortified pas. .with. Wow 1: on yawavl yushi.kh. setup 1.

C in: -., The jack pad is adapted for throwing out long pieces. In addition, the drive pusher i; The form of vpta with aika is not reliable in operation, since at high speeds the transfer of the screw-nut quickly wears out.

There is a known cargo dumper, which includes a housing, a slider, on which a horizontal pusher with a collision beam and a drive 2 are pivotally fixed.

The disadvantage of such a device is that the colliding beam is rigidly fixed at the end of the pusher. When the load is dropped, which is deployed relative to the axis of the conveyor belt, the impact is perceived by one end of the beam. The bending moment is transmitted to

fixing beams and pusher. Under the action of this moment, the beam may break at the place of attachment or the pusher gets stuck in the guides.

 invention is to increase the reliability of the ejector.

The goal is achieved by the fact that the colliding beam is pivotally fixed. The test is at the end of the pusher and additionally

.,. narnirno connected retaining lamellar springs of the bend, located on the sides of the pusher, with the slide.

FIG. I depicts the described Sras-va gel cargo, top view; in fig. 2, node I in FIG. one; in fig. 3 - cargo dropper, sectional side view; in fig. 4 is a view along arrow A in FIG. 3; in fig. 5 - cargo dumper, top view

The load release device comprises a housing / with guide rods 2 on which a slider 3 is mounted. On the slider 3 it is hinged in a vertical

and horizontal tappet 4. No. p .-) the bristle x is fixed

At the end of the pusher 4, the pusher beam 5 is perpendicularly fixed to the colliding beam 5, which is additionally also connected by means of hinges with bending plate springs 6 arranged along

to the sides of the pusher 4, with the slider 3. Instead of pushing the beams 5 on the end of the pusher 4, the platform 7 can be fixed (see Fig. 2). In the housing / resetter (see Fig. 3) are located chain transmission 8, including, and the driving sprocket 9 mounted on the shaft of the electric motor 10, n driven sprocket U /; and a chain drive gear 72 enveloping the sprocket 13 and the driven sprocket 14. On the upper branch of the gear 12, a slider 3 of the protrusion 15 is fastened. In the initial position of the crawl-on 3, an elastic retainer / with a slot 17 is installed (see FIG. 4), with which the rod 18 mounted on the slider interacts. connected to tensioning devices 19. secured at the ends of the leaf-shaped bending springs 20, mounted-to; by its bases in housing 1 of the resetter. For constant tension chain. gears 8 and 12 and shock absorbing, the pusher 4 is preloaded with the help of nuts 21 of tensioning devices 19. At the ends of the slide, shock absorbers 22 are mounted.

The cargo dumper works according to the word ..:;

When a command is issued to reset the load 23, the electric motor 10 is turned on, which rotates the drive sprocket 13 of the slider 3 by means of a chain gear 8. The asterisk 13 indicates the movement of the thrust chain 12 on which the slider 2 is fixed. The pusher 4 hinged on the slide 3 em translational movement in the direction of discharge of cargo 23 and pushes him beam 5 in the drive. At the end of the working stroke, the slider 3 acts on a track switch (not shown), which switches the motor 10 to reverse rotation and idling of the slide 3. Before the end of idling, there is also a path switch (not shown) that disconnects the motor 10. In The initial position of the pusher 4 comes due to the inertia of the moving masses. At the end of idling (in the initial position), the slider 3 is fixed by means of an elastic latch 16 by tilting the rod 18 of the slider 3 into the slot 17 of the latch 16.

Chain: 1 and 8 in 12 in ip-Miecce works1, wear and elongation g-.s. In order to improve the tension of the chains, the lamellar springs of the bend 20 and the buckle are forced by a certain force to the position, with the three-pointed diagrams, with noMOHibio nuts 2 / tensioning devices 19.
