Optimized Structure Design of a Cone Bottom Silo
This utility model relates to an advanced structural design of a cone bottom silo, which consists of three core components: the main body structure, an automatic feeding system, and a temperature control module. The feeding mechanism is installed at the top of the silo, while the temperature control unit is mounted beneath it, forming an integrated design layout. The main structure includes the steel silo body, mounting base, support legs, and protective cover, which significantly enhance the stability and service life of the device.
Efficient Feeding Mechanism with Adjustable Structure
The feeding system comprises several components including a fixed frame, drive motor, rotating shaft, lead screw system, movable seat, positioning nut, connecting rod, slider assembly, placement board, and electric actuators. The fixed frame is mounted at the front end of the cone bottom silo to support the upper transmission structure. The drive motor, installed at the top inside the frame, rotates the shaft, which in turn drives the lead screw. This motion adjusts the positioning nut vertically, thereby controlling the slider and the placement platform’s height.
Operators can place materials directly onto the platform, which then drops them into the silo body automatically. This automated system eliminates the need for manual lifting, significantly improving operational safety and efficiency—especially in high-frequency usage environments.
Coordinated Operation Between Platform and Electric Actuators
The positioning nut connects to a connecting rod on the right side, with a slider mounted on its upper end. Engineers design the slider to support the placement board and secure an electric push rod at its front end. They then mount a secondary actuator—the electric thrust rod—onto the top section of the electric push rod. This setup raises the movable plate on top and slides materials into the cone bottom silo.
This part of the system optimizes the entire feeding process, reduces manual intervention, and ensures safe and continuous material handling.
Intelligent Temperature Control System for Stable Storage Conditions
The device includes a temperature control mechanism composed of a waterproof plate, battery unit, conductor cooler, heater, drying tube, connector blocks, mesh connector, and temperature sensor. The waterproof plate is mounted inside the upper part of the base to prevent water ingress. The battery, fixed on top of the waterproof plate, powers the conductor cooler and heater, both of which regulate the internal temperature of the cone bottom silo.
A drying tube is positioned above the heater to keep the internal environment dry. Connector blocks and mesh assemblies provide structural linkage, while the temperature sensor, fixed on the outer wall of the silo, monitors temperature changes in real time, enabling intelligent thermal regulation.
Key Advantages and Practical Value
1. Improved Feeding Efficiency
The innovative feeding mechanism allows users to adjust the platform height via the positioning nut, enabling easy and efficient material placement into the cone bottom silos. This feature reduces labor intensity and enhances user safety.
2. Reliable Temperature Regulation
The integrated conductor cooler and heater ensure a stable internal temperature, which is essential for effective grain storage. The system improves the overall storage quality and performance of the cone bottom silo.
3. Enhanced Structural Integrity and Sealing
The support legs and mounting base stabilize the entire unit, while the protective cover seals the silo effectively against dust and water. These features increase the cone bottom silo‘s durability and adaptability to various environments.
