Description

(54) BUCK CONVEYOR

one

The invention relates to industrial vehicles, namely bucket conveyors.

A bucket conveyor is known, which contains a closed chain organ with attached arms, on which tipping buckets 1 are articulated.

In this conveyor, it is impossible to continuously load the material into the buckets, since at this time the material clogs the conveyor, it falls into the gaps between the buckets.

Also known is a bucket elevator containing a closed circuit with attached straps on which tilting buckets are hinged, and casings attached to the slots in the gaps between the buckets and made in the form of two inclined, overlapping adjacent walls of buckets of canopies 2.

This conveyor allows the material to be continuously loaded into the buckets, due to the presence of shells in the gaps between the buckets. However, this conveyor still allows the material to be cut. This disadvantage is exacerbated when small piece metal items are loaded.

and weight. In a known conveyor, tipping of the buckets is perpendicular to the direction of transport, which leads to the fact that the covers are forced to be installed at a considerable distance from the upper ends of the buckets, otherwise they simply will not allow the buckets to turn. Falls from the metering hopper parts can be rebashed from the hoods of the covers and fall outside the bucket.

In addition, as practice shows, the operation of such conveyors, turn

10 buckets perpendicular to the direction of transport is unfavorable from the point of view of the dynamic interaction of its components and the reliability of operation. With such a turn, it is possible that the neck is wedged, leading to a stop of the conveyor.

The purpose of the invention is to increase the reliability of operation with continuous loading of buckets.

This goal is achieved by the fact that the conveyor is equipped with fences made in the form of brushes installed in the loading area of the buckets on either side of them with the possibility of interaction with the upper parts of their side walls.

In addition, the hinge axis of each bucket with a thrust is located perpendicular to the direction of transport under the upper end surface of the front wall of the bucket, and the casing is mounted on the tractor with the ability to interact with the upper ends of the adjacent buckets.

FIG. 1 shows a section of a bucket conveyor in an isometric view; in fig. 2 is a section A-A in FIG. one; in fig. 3 - section of the transport conveyor, side view.

The conveyor contains a closed articulated chain 1 with attached to it 2 rods, on which tipping buckets 3 are hinged. The casings 4 are mounted on the rods 2 in the gaps between the buckets and are made in the form of two inclined roofs that overlap adjacent walls of the buckets.

The conveyor is also provided with elastic fences made in the form of two brushes 5 and 6 installed in the loading area of the buckets 3 on both sides of the buckets with the possibility of interaction with their upper parts of their side walls.

The hinge axis 7 of each bucket 3 with a tightness 2 is perpendicular to the direction of transport below the upper end surface of the bucket 3 and in front of it. The casing 4 is mounted on bar 2 with the ability of its visors to interact with the upper ends of the respective buckets 3, so that the inclined surfaces of the peaks go directly into the capacity of the buckets 3.

Chain 1 is enclosed in guides 8 and 9, made of 1 well profile. On the legs 2, the support rollers 10 and 11 are mounted, which cooperate with the guides. 8 and 9, and the chain 1 is fitted with rollers 12, interacting with the inner side, channel guides 8 and 9, which serve to improve the movement of the chain along a closed horizontal contour.

The conveyor is also provided with guides 13 and 14, located on both sides of the bucket 3, which are provided with rollers 15 and 16 that interact with these guides.

Bucket conveyor works as follows.

When you turn on the conveyor chain comes in continuous movement along a closed path. The path of the conveyor passes over the receiving bins of a number of automatic lines. At a control signal (not shown), the buckets 3 begin to be filled with metal piece blanks, which are continuously fed through the tray of the hopper. In the loading area, the buckets 3 (Figs. 1 and 2) are tightly covered on the sides with brushes 5 and b, so that the contact portion of the bristles of the brushes are slit. This is necessary in order to eliminate the gap between the fence and the buckets 3, so that the workpiece does not fall into it and the conveyor does not jam. The buckets 2 are moved along the guides 13 and 14 with a constant slight backlash in the longitudinal direction, which is compensated in the loading zone by the brushes 5 and 6.

Metal blanks coming along the tray fall into the buckets 3 or on the surface of the visors of the casing 4, from which they roll into the buckets 3. The housings 4 are installed near the buckets 3, so that the inclined canopies directly break into the container with buckets, which allows the tray to be approached directly buckets 3. In this case, metal parts during their fall recruit a relatively small kinetic energy, which reduces the amount of possible ricochet of parts from the visors of the casing. Parts that otrekochetirovan from visors and did not fall into the buckets, hit the elastic bristles of the brushes 5 and 6 and fall into the buckets 3.

The filled buckets 3 are transported by the chain 1 to the hoppers of the automated lines. Above the respective bunker, the guides 13 and 14 have an open controllable portion of the arrow (not shown), where the buckets 3 are destroyed by tilting in the direction of travel (Fig. 3). Then, the overturned buckets 3 are returned to their original position by means of an inclined branch of the guides, with which the rollers 15 and 16 interact.

Thereafter, the buckets 3 are transported by the chain 1 again to the loading position and the cycle of operation is repeated.

The described implementation of the conveyor increases the reliability of its operation by reducing the material spillage during continuous loading of buckets.
