Screw Conveyor with Hopper

Screw Conveyor with hopper

Grain transport begins with the direct discharge of grain into the loading hopper located at the lower part of the conveyor, most often directly from a trailer. The user can regulate the transport capacity using the shutter installed at the inlet to the working area of the conveyor.

The motor and drive system, positioned at the base of the screw conveyor, stabilize the machine by adding weight without stressing the tubular segments. This design allows for easier access to the drive system for maintenance and adjustment.

The discharge height is adjustable using a crank and a wire rope winch mounted on the conveyor’s chassis. The gear ratio is selected to ensure relatively easy and safe raising and lowering of the discharge.

The chassis is constructed from wide steel profiles, appropriately sized to match the conveyor’s dimensions. It ensures both safety and stability during operation.

Another important aspect from the user’s perspective is ensuring the mobility of the screw conveyor and the ability to move it around the farm. Therefore, the machine is equipped with a pair of sturdy large front wheels and two pairs of swivel wheels at the rear.

Key Features of the Screw Conveyor:

• High real transport efficiency – up to 15, 30, and 50 t/h;
• Adjustable discharge height using a crank, based on a winch system;
• Modular conveyor design, with lengths ranging from 4 to 12 meters, depending on the use of 1-meter or 2-meter extension segments;
• The screw is bearing-supported and lubricated in each segment (every 2 meters), which significantly enhances the device’s durability, extends the lifespan of support bearings, stiffens the external tube, and ensures quiet operation;
• The conveyor is suitable for outdoor operation and storage – hot-dip galvanized with a thick protective coating and an aesthetically glossy surface;
• Large wheels suitable for all types of terrain;
• Adapted for loading grain silos through an opening in the top cover;
• Low purchase and operating costs compared to other transport devices, especially pneumatic conveyors.

Technical Specifications

When ordering, please refer to the conveyor symbol, e.g., 250/10-12/OC – D, where:

• 250 indicates the tube diameter of the conveyor in mm,
• 10 is the minimum conveyor length in meters,
• 12 is the maximum working length of the conveyor (achieved by purchasing an additional extension segment),
• OC means the conveyor is hot-dip galvanized,
• D indicates a bottom-drive conveyor with material intake through a loading hopper.

Extension Segments

When ordering, please refer to the segment symbol, e.g., 250/2/OC, where:

• 250 indicates the tube diameter of the conveyor in mm,
• 2 is the segment length in meters,
• OC means the conveyor is hot-dip galvanized.

Optional rotating discharge chutes are available for screw conveyors.
