With universal joint bearings, a single unit can cover a conveying range of 30 meters horizontally and 6 meters vertically. Airtightness: The fully enclosed structure reduces dust emissions by over 90%, minimizing material spillage during transport.

Main Structure of the Grain Pumping Portable Grain Suction Auger Screw Conveyor Small

The Grain Pumping Portable Grain Suction Auger Screw Conveyor Small consists of four main parts: a power system, a conveying channel, a suction and discharge device, and a supporting moving structure. These components work together to achieve lightweight and efficient grain transfer.

Power System: Utilizing a small motor and reduction mechanism integrated design, it is compatible with most household 220V power supplies. Compact in size and lightweight, it operates stably, providing continuous rotational power to the equipment. Some models support speed adjustment to adapt to different grain types.

Conveying Channel: Constructed with high-strength flexible hose or stainless steel, it features internally manganese steel stamped spiral blades. The screw pitch matches the hose's inner diameter, ensuring even grain propulsion. The hose can be flexibly bent to adapt to narrow spaces.

Suction and discharge device: Includes a conical suction port and discharge port. The suction port is designed to reach deep into the grain pile, reducing suction resistance; the discharge port can connect to a flexible hose or directly connect to the grain storage container to prevent grain spillage.

How does the Grain Pumping Portable Grain Suction Auger Screw Conveyor Small work?

The Grain Pumping Portable Grain Suction Auger Screw Conveyor Small achieves grain conveying through a combination of "negative pressure suction + spiral pushing." Upon startup, the power system drives the motor to rotate the reduction mechanism, which in turn rotates the spiral blades inside the conveying hose. The negative pressure generated at the suction port by the rotating blades draws the grain particles from the grain pile into the hose. The grain entering the hose is continuously pushed by the rotating spiral blades, which exert axial thrust on the grain. Simultaneously, the friction between the grain and the inner wall of the hose prevents the grain from rotating synchronously with the blades, allowing the grain to move smoothly forward along the inner wall of the hose and finally be precisely delivered to the grain storage container through the discharge port.

Technical Specifications of the Grain Pumping Portable Grain Suction Auger Screw Conveyor Small

What are the application scenarios for the Grain Pumping Portable Grain Suction Auger Screw Conveyor Small?

Application scenarios for the Grain Pumping Portable Grain Suction Auger Screw Conveyor Small include: emptying grain storage in households, replenishing rice containers, bagging grain after drying in the fields for small farmers, and cleaning up leftover grain in corners of grain warehouses. It is suitable for transporting various types of granular grains.

Field Applications: Works with harvesters to enable immediate loading of crops such as wheat and rice, reducing losses during the drying process.

Family Farms: Used for short-distance transportation of feed ingredients (such as corn and soybean meal) from warehouses to farms.

Flour Mills: Transports cleaned wheat grains to the mill, completing preliminary mixing during the transport process.

Feed Mills: Uses a twin-screw conveyor to transport multiple raw materials to the mixer in proportion, with an accuracy error of ≤1%.

Port Terminals: Vertical screw conveyors enable rapid unloading of grain from ship holds to warehouses, with a daily processing capacity exceeding 2000 tons.

Cold Chain Logistics: Stainless steel models are designed for low-temperature environments, transporting frozen corn, soybeans, and other food items.

What is the price of the Grain Pumping Portable Grain Suction Auger Screw Conveyor Small?

The price of DaHan Machinery's Portable Grain Suction Auger Screw Conveyor Small starts from $80, with a tiered price range influenced by equipment configuration and features. Basic models typically have manually adjustable supports and smaller pipe diameters, suitable for small-scale grain transport by households. Mid-range models feature foldable supports, casters, and speed adjustment, with pipe diameters of 80-100mm, offering superior conveying efficiency and portability. High-end models use food-grade contact materials and thickened screw blades, with some models supporting customized lengths, suitable for frequent use by small farmers or small grain stores. Price differences mainly stem from materials, conveying length, motor power, and additional features, offering excellent overall value and meeting the needs of different users' budgets and usage scenarios.

Frequently Asked Questions

What are the characteristics of the conveyed material? Is the flow rate good or poor? Is it wet or dry?

Suitable for granular and powdery materials, such as wheat, corn, and starch. High-moisture materials that are prone to sticking and clogging are not recommended. Flow rate is adapted to demand; basic models offer 1-3 tons per hour, while mid-range models offer 3-5 tons per hour, meeting the needs of households/small farmers.

Bulk density of conveyed material = ? kg/m³

The suitable bulk density for grain materials is mostly 600-800 kg/m³. For example, wheat is approximately 750-800 kg/m³, corn 650-700 kg/m³, and rice 550-600 kg/m³ (dry state). The equipment is designed to accommodate this density range to ensure minimal clogging during conveying.

Conveying capacity = ? m³/h

This needs to be determined based on your conveying method and the material being conveyed. Generally, the maximum conveying capacity for horizontal conveyors can reach 20 tons per hour.

Transport Length = ?M

Our flexible hose type single unit can reach a maximum length of 30 meters. For longer distances, it needs to be used in series. The stainless steel type can reach a length of 4 meters.

Conveyor Can Be Horizontal, Inclined, or Vertical

Our equipment supports three installation methods: horizontal, inclined, and vertical. Horizontal installation is suitable for short-distance planar transport. Inclined installation allows the angle to be adjusted via brackets. Vertical installation can reach 90°, but the height is limited to 6 meters.
