Technical Field

[0001] This utility model relates to the field of ship unloading machine technology, specifically to a receiving trolley for a screw unloader. Background Technology

[0002] A screw unloader is a type of continuous bulk material unloading machinery that uses the mechanical rotation of a screw mechanism to vertically lift and horizontally transport materials to a conveying system on a dock. It mainly consists of a vertical boom, a horizontal boom, a turntable, a gantry, and a feeder. The vertical and horizontal booms are equipped with helical blade conveyors, and the head of the vertical boom has a reverse screw feeder. Existing screw unloaders suffer from frequent material blockage problems.

[0003] To solve the problem of material blockage in screw unloaders, the current conventional solution is to move the bucket of a wheel loader under the screw unloader, then move the vertical screw feeder above the bucket, reverse the screw to remove the conveyed medium, and use the bucket below to hold the medium.

[0004] However, due to the arc-shaped structure at the bottom of the bucket and its insufficient depth, it is difficult to effectively wrap the vertical screw feeder. Furthermore, because the screw speed is high, the centrifugal force is large during operation. During the reverse screw rotation, a large amount of conveying medium is easily thrown out to the outside, causing serious ground cleaning and environmental pollution. Utility Model Content

[0005] The purpose of this invention is to overcome the environmental pollution caused by the inconvenience of collection in the existing technology, and to provide a receiving trolley for a screw unloader that has the advantages of easy collection and reduced pollution.
