Description

(54) BUCKET CONVEYOR

one

The invention can be used in the chemical industry and agriculture for transporting molten viscous materials that solidify during transport.

Bucket conveyors are known, including a frame, driving and tensioning stations, transporting chains, on which buckets are fixed by means of trunnions, a device for tipping buckets.

However, these conveyors are suitable only for bulk materials, as unloading by bucket tipping over viscous, adhering to the walls of the buckets or hardening materials during transportation is difficult or impossible;

The aim of the invention is the possibility of unloading materials that are loaded in a liquid state and solidify during the transfer process.

This is achieved by the fact that the proposed conveyor is provided with a duct fixed at one end to a trunnion, which has an opening for supplying compressed air, and the other end to the bottom of the bucket, which is made with a hole and a recess.

FIG. I shows the proposed conveyor, general view; in fig. 2 shows a section along A-A in FIG. one; in fig. 3-section along BB in FIG. 2

The bucket conveyor consists of frame 1, bypass 2 and drive 3 heads, drive 4, lamellar two-way roller chain 5, on which buckets 7 are fastened with trunnions 6. in the trunnion 6. At the unloading point, the nozzle 10 of the line is connected to the hole in the trunnion 6 with compressed air.

Bucket conveyor works as follows.

Before the molten material is poured into the bucket, the recess located at the bottom of the bucket is covered with a sheet of cellophane or thick paper, the dimensions of which are slightly larger than the length and width of this recess. The laying of the elastic material can be done automatically or by the operator. After pouring, a cavity filled with air is created in said recess. When the molten material is transported, it solidifies. At the place of unloading, due to the tilting device consisting of a fixed stop and cantilever rollers, the bucket overturns, and it moves for a certain time in an inverted polishing. At this time, to the hole on the trunnion 6, which ends the duct 9, coming from the bottom

parts of the bucket 7, automatically or by the operator servicing the conveyor, connect and supply compressed air from the main. The compressed air enters the closed space at the bottom of the bucket 7, insulated with a material that has been poured at the beginning of transportation, solidified and stuck to the walls of the bucket.

Thus, the ejection begins to act on the casting, and the force, determined by the pressure of compressed air and continuous, recesses in the bottom part of the bucket, causing the casting to detach from the walls of the bucket. After separation, the casting falls under its own weight.
