Description

Technical Field

[0001] The utility model relates to the technical field of powder material conveying, in particular to an automatic telescopic feeding device. Background Art

[0002] The method of transporting quicklime powder, fly ash, mineral powder, etc. is to use tank trucks to transport the powdered ore to the storage tank point, and then the high-pressure system inside the tank truck transports the powdered material through pipelines to various power tanks.

[0003] At present, after the tank truck has finished delivering materials, it is difficult for people to move the powder conveying pipe and the high-pressure air pipe because they are heavy. The powder conveying pipe and the high-pressure air pipe extending outside are heavy and easily damaged. The free ends of the powder conveying pipe and the high-pressure air pipe cannot be reasonably stored. At the same time, the residual powder in the powder conveying pipe is likely to cause environmental pollution.

[0004] For this purpose, we propose an automatic telescopic feeding device. Utility Model Content

[0005] The utility model mainly solves the above technical problems and provides an automatic telescopic feeding device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatic telescopic feeding device, comprising two groups of anchor steel bars, a powder delivery pipe, a high-pressure air pipe and a wall; a steel plate is fixedly installed on the anchor steel bars; a bracket is fixedly installed on the two groups of steel plates; a vertically upwardly distributed column is fixedly installed in the bracket; the two groups of the columns are symmetrically distributed left and right; a central axis is provided inside the bracket; a sliding connection sleeve is slidably installed on the column; a shaft sleeve is fixedly installed on the side where the two groups of the sliding connection sleeves are close to each other; the central axis is movably installed between the two groups of shaft sleeves; two groups of pulleys are fixedly installed on the outer circle of the central axis;

[0007] An electric winch is provided on the top surface of the bracket, and a suspension rope is wound on the electric winch. The free end of the suspension rope is movably connected to the central axis. The electric winch is controlled to wind and release the suspension rope, so that the suspension rope pulls the central axis to slide freely up and down inside the bracket. By controlling the height of the central axis, the distribution height of the free ends of the powder conveying pipe and the high-pressure air pipe can be conveniently controlled.

[0008] Preferably, the free ends of the powder conveying pipe and the high-pressure air pipe extend outwards through corresponding pulleys respectively.

[0009] Preferably, the powder delivery pipe is fixedly connected to the powder bin, and the high-pressure air pipe is fixedly connected to the air pressure pump.

[0010] Preferably, a feed inlet is provided through the wall, and two groups of inclined fixed slideways are fixedly installed on the inner wall surface of the wall corresponding to the feed inlet.

[0011] Preferably, the free ends of the powder conveying pipe and the high-pressure air pipe are both slidably mounted on corresponding fixed slideways.

[0012] Preferably, a small material receiving bucket is fixedly mounted on the outer side of the wall.

[0013] Beneficial Effects

[0014] The utility model provides an automatic telescopic feeding device, which has the following beneficial effects:

[0015] (1) The automatic telescopic feeding device controls the electric winch to reel in and release the suspension rope, so that the suspension rope pulls the central axis to slide freely up and down inside the bracket. By controlling the height of the central axis, the distribution height of the free ends of the powder conveying pipe and the high-pressure air pipe can be conveniently controlled. When feeding powder, the central axis is controlled to slide downward, so that the free end of the powder conveying pipe slides downward along the corresponding fixed slideway and passes through the feeding port on the wall to be distributed outward. The control valve on the powder conveying pipe is opened, so that the powder in the tank truck is fed into the powder bin through the powder conveying pipe under the action of the high-pressure airflow, thereby achieving the effect of facilitating the control of the position of the free end of the powder conveying pipe.

[0016] (2) After the feeding is completed, the automatic telescopic feeding device can collect the residual powder in the powder conveying pipe through the provided material receiving bucket to avoid the waste of powder. After the feeding is completed, the central axis is controlled to slide upward, so that the free ends of the powder conveying pipe and the high-pressure air pipe slide upward along the fixed slideway, so that the free ends of the powder conveying pipe and the high-pressure air pipe are separated from the feeding port on the wall and return to the inner side of the wall, which protects the free ends of the powder conveying pipe and the high-pressure air pipe and avoids the free ends of the powder conveying pipe and the high-pressure air pipe from being retained on the outside of the wall and being easily damaged, thereby achieving the effect of protecting the powder conveying pipe and the high-pressure air pipe.
