Grain Loading Spout - Telescopic Loading Spout & Telescopic Chute

Grain Loading Spout

A telescopic loading spout, also referred to as telescopic chute or loading bellows, is professional bulk material handling equipment. Darko grain-specific model is designed dedicatedly for Grain Loading Spout applications, ideal for bulk handling of wheat, corn, rice, soybeans and other granular grains.

It perfectly adapts to trucks, railway wagons, grain silos, barges and port ship loading scenarios. With a fully enclosed dust suppression design, it effectively reduces grain breakage, minimizes material loss and delivers eco-friendly dust-free loading for all grain storage, transportation and processing facilities.

Grain Loading Spouts
The complete telescopic loading spout consists of seven core components, featuring stable structure, easy disassembly and assembly, and suitable for long-term continuous operation:
  • Top Drive Mounting Frame:Fixes the main equipment body, connects to grain silo discharge port or conveying equipment, and bears the overall machine weight.
  • Central Diversion Telescopic Chute:Core material guiding component with buffer structure to reduce grain falling impact and lower breakage rate.
  • Steel Rope Lifting System:Adopts three-rope hoisting mode equipped with K-series reducer, delivering high transmission efficiency, stable operation and reduced steel rope wear.
  • Multi-Layer Telescopic Loading Bellows:Flexible sealing component available in food-grade and wear-resistant materials to prevent dust overflow.
  • External Dust-Proof Enclosure:Fully enclosed design locks loading dust inside the equipment to meet environmental protection requirements.
  • Bottom Dust-Proof Sealing Skirt:Fits closely to the material pile surface for effective dust isolation, perfectly adapting to the soft characteristics of grain.
  • Intelligent Electrical Control System:Detects material level in real time, automatically controls equipment lifting, and supports manual and automatic dual-mode switching.

Standard Structure & Features

Working Principle of Telescopic Loading Spout

The working principle of the telescopic loading spout is simple and reliable, realizing automatic dust-free operation in the whole process:
  1. Equipment Fixation

    Fix the telescopic loading spout at the bottom of grain silo discharge ports or belt conveyors via the top drive mounting frame for firm installation and stable operation.
  2. Initial Operation

    After startup, the intelligent control system drives the steel rope lifting system to lower the central telescopic chute and telescopic loading bellows synchronously, keeping the bottom dust-proof sealing skirt close to the loading container bottom or material pile surface.
  3. Material Conveying

    Bulk grain flows smoothly through the central diversion telescopic chute. The buffer structure effectively avoids grain breakage and dust emission caused by material impact.
  4. Automatic Lifting

    As the material pile height increases, the intelligent control system detects material level changes in real time, and automatically drives the steel rope lifting system to raise the main body of the telescopic loading spout synchronously.
  5. Dust-Proof Closed Loop
    The bottom dust-proof skirt always keeps a proper distance above the grain pile. The external dust-proof enclosure and telescopic loading bellows form a closed space, trapping impact dust completely and realizing dust-free, low-breakage and spillage-free loading.

Customization Services

Darko provides customers with one-stop custom solutions for telescopic loading chutes and chutes. We tailor the equipment’s telescopic stroke, pipe diameter, plate thickness, and intelligent control systems based on on-site silo dimensions, loading height, material characteristics, and truck models, ensuring that the truck loading chutes are perfectly suited for all types of bulk material conveying production lines.

Can the telescopic travel and diameter be customized?
 Yes. Full non-standard customization is available for inlet diameter, telescopic travel, handling capacity and main material.
Can bulk material belt conveyor systems be customized?

Yes. Darko supports full non-standard customization for belt conveyor systems. We can tailor the length, width, conveying capacity, inclination angle, material and drive configuration according to actual working conditions, to perfectly match your bulk material handling production line.

Can the telescopic loading bellows be replaced separately?
Yes. Modular design enables independent disassembly and replacement, making daily maintenance simple and cost-effective.
Is this equipment suitable for outdoor operations?
Yes. Optional outdoor rain cover and weather-resistant material ensure stable operation under harsh outdoor conditions.
Is it possible to automate the tanker loading process?
Absolutely. Modern tanker loading spouts are equipped with “slack cable” and “level sensors” (such as rotary paddles or vibrating probes). These sensors detect when the material reaches the top of the tanker, automatically stopping the flow and retracting the spout to its home position, which significantly improves loading speed and prevents overfilling.
