AI Technical Summary

Technical Problem

Existing chain conveyor protective fences lack effective rainproof and drainage structures, causing rainwater to seep into the equipment, leading to corrosion and a decrease in the coefficient of friction. At the same time, the high-temperature environment accelerates the aging of rubber components, affecting the equipment's lifespan and material quality.

Method used

A protective fence structure including a water guide plate, a sunshade plate, uprights, and a lifting plate was designed. The arc design of the water guide plate and uprights allows rainwater to drain, the sunshade plate blocks sunlight, the vents in the uprights promote ventilation, and the lifting plate adjusts its height to accommodate different material requirements.

Benefits of technology

It enables the orderly drainage of rainwater, prevents equipment corrosion and high-temperature aging, reduces the internal temperature of the equipment, enhances connection strength and waterproof performance, and adapts to the transmission needs of materials at different heights.

Abstract

The utility model discloses a protective fence structure of a chain conveyor, which relates to the technical field of protective equipment for conveyors and comprises two main protective plates arranged on two sides of a conveyor belt, positioning grooves are arranged at the tops of the main protective plates, a water guide plate is arranged above the main protective plates, the water guide plate is an arc plate with a higher middle part and two lower ends, and the water guide plate is arranged in the positioning grooves. Connecting blocks are fixed to the two ends of the bottom of the water guide plate, positioning blocks capable of being inserted into the positioning grooves are fixed to the bottoms of the connecting blocks, and the two ends of the water guide plate extend to the sides of the two main protection plates. Two vertical plates are fixed to the two ends of the top of the water guide plate, a sun shield is fixed to the tops of the vertical plates and is an arc plate with the lower middle and the two higher ends, a water falling groove is formed in the middle of the sun shield in a penetrating mode, and water outlet grooves are formed in the ends, close to the water guide plate, of the vertical plates. A lifting plate is arranged for increasing the height of the water guide plate; a rainproof drainage system is constructed, and the height of the protective fence can be adjusted according to the height of actual conveyed materials.
