What is a grain suction machine hose?

Grain suction machine hose is a kind of equipment specially used for efficient transportation and suction of grain and other granular materials. The equipment transports grain from one place to another through the negative pressure of the hose, which is suitable for grain processing, warehousing and transportation industries. The suction speed can be adjusted according to demand, generally 5-20 tons/hour. The screening mesh is usually 20-80 mesh, which is used to ensure the purity of the material during the transportation process and avoid the mixing of impurities to adapt to materials of different particle sizes.

Working principle of a grain suction machine hose 

Grain suction machines hose generally use a vacuum pump or fan to generate negative pressure, form airflow in the hose, and suck the grain into the pipeline. The material flows with the airflow and is eventually sent to the discharge port. Its key components include suction hoses, conveying hosts, power units (usually motors or diesel engines), and collection devices.

Structural composition of a grain suction machine hose

Power unit: Usually an electric motor, gasoline engine, or diesel engine is used as a power source to provide power for the operation of the suction machine.

Spiral device: Generally, an axisless spiral spring made of manganese steel has good hardness and elasticity. The outer edge is specially treated to be smooth and will not cause damage to the pipe.

Conveying pipelines: tendon tubes, steel wire tubes, or high-strength PVC hoses are mostly used. These hoses are cold-resistant, corrosion-resistant, wear-resistant, and impact-resistant. They can be bent arbitrarily, making them convenient for use in different sites and environments.

Head and tail: The design is humanized, easy to operate and connect. The head is generally equipped with a feed port, and the tail is connected to the power device and the discharge port.

What are the advantages of a grain suction machine hose?

High conveying efficiency: It can quickly transport grains from one location to another, and the conveying volume per hour can reach several tons or even tens of tons.

Low breakage rate: During the transportation process, the breakage rate of grains is low, which can ensure the quality and integrity of grains.

Wide range of applications: It is not only suitable for various grains such as wheat, corn, soybeans, rice, sorghum, but also can be used to transport chemical particles, plastic particles and other materials with high hardness and not easy to break.

Easy to move: small size, light weight, bendable top, easy to move and carry, convenient for use in warehouses, loading, stacking and other occasions, and can be flexibly applied to different work sites, such as farms, grain depots, docks, etc.

Common grains and recommended mesh for grain suction machine hose

The following is the mesh recommendation for common grains:

Rice: The particle size is about 2-5mm, and a 20-40 mesh screen is recommended. It can effectively filter husks and fine particles while avoiding clogging.

Corn: The diameter is about 4-8mm, and a 10-30 mesh screen is recommended. As the corn particles increase, the mesh aperture can be slightly larger to ensure the consistency of the pipeline.

Wheat: The diameter is about 2-4mm, and a 30-50 mesh screen is recommended. Wheat has higher requirements for cleanliness and needs to be filtered finer.

Soybean: The diameter is about 3-6mm, and a 20-40 mesh screen is recommended to balance efficiency and individual filtration.

Other materials (such as plastic particles, sand and gravel): According to the particle selection, plastic particles usually use 40-80 mesh, and sand and gravel may require 10-20 mesh.

Purpose of use	Recommended mesh range	Description
Coarse filtration (prevent stones and foreign objects)	5 mesh~10 mesh	Applicable to the grain suction port to prevent large debris from entering the pipeline
Medium filtration (prevent small impurities)	20 mesh~40 mesh	Prevent small stones, straw segments and other impurities
Dust filtration (end dust removal)	80 mesh~120 mesh	Mostly used at the front end of the fan or dust removal device to protect equipment

Application of grain suction machine hose 

Farm operation: In the farm, it can be used to transport grain harvested from the field to the warehouse for storage, or to transport grain in the warehouse to the transport vehicle for convenient transportation to the market or processing plant.

Grain warehouse management: Grain suction machine is suitable for grain warehouse replenishment, warehouse discharge, warehouse turnover, stacking and other operations, to achieve efficient handling and storage management of grain.

Wharf loading and unloading: At the dock, the grain on the ship can be quickly unloaded to the warehouse or transport vehicle on the shore, and the grain in the warehouse can also be loaded on the ship to improve the loading and unloading efficiency of the dock.

Grain processing industry: In flour mills, rice mills, feed mills and other grain processing enterprises, it is used to transport grain from the raw material warehouse to the processing equipment to realize the automated production process.

Selection recommendation of grain suction machine hose 

Transportation volume: According to the actual production needs, determine the amount of grain that needs to be transported per hour. Small farms or processing enterprises may need to transport several tons of grain per hour, while large grain warehouses or docks need to transport tens or even hundreds of tons per hour. The conveying capacity of common grain suction machines hose ranges from 3-5 tons to 50-100 tons per hour. The appropriate model can be selected according to the specific output.

Conveying distance: Consider the horizontal distance and vertical height of the suction machine from the feeding point to the discharging point. The horizontal conveying distance generally ranges from tens of meters to hundreds of meters, and the vertical lifting height is usually from a few meters to more than ten meters. If the conveying distance is long or the lifting height is high, it is necessary to select a grain suction machine hose with higher power and stronger conveying capacity to ensure that the grain can be smoothly conveyed.

Grain characteristics: The particle size, shape, density, humidity and other characteristics of different grains will affect the selection of suction machines. For example, corn grains are larger, so it is necessary to select a grain suction machine hose with a larger diameter of the feed port and conveying pipeline; while for grains with higher humidity such as rice, it may be necessary to consider the anti-blocking and moisture-proof performance of the suction machine.
