Overview

This product is widely used in conveying machines for discharging materials in mining, metallurgy, electrical fields, coal handling stations, port wharfs, and other similar applications. The hydraulic scraper discharger is a mechanical product installed on the intermediate frame of a belt conveyor, responsible for discharging materials and controlling the flow rate and direction of material conveyance. It can evenly and continuously discharge materials conveyed by the belt into hoppers or designated locations. This discharger features an adjustable trough angle and auxiliary scraper blades, and utilizes an electro-hydraulic pushrod as the power source, overcoming the shortcomings of traditional dischargers, such as incomplete scraping of material, scraping the belt, poor overload capacity, and susceptibility to mechanical damage. The DYTN type single-sided and double-sided wear-resistant discharger is powered by an electro-hydraulic pushrod. During operation, the pushrod extends to drive the rod, which in turn drives the carriage to lower the head, supporting the flat roller assembly, ensuring the working surface of the belt is flat. The head is tightly seated against the belt surface, discharging the material from the belt into the hopper and transporting it to the desired location. After discharging, the electro-hydraulic pushrod retracts to pull back the drive rod, lifting the scraper head, allowing the adjustable roller assembly to transition from flat to trough shape, enabling the material to pass smoothly (the principle of operation of the electro-hydraulic pushrod is explained in the pushrod section).

Features

1. The power source drive section is the domestic new generation of dual-purpose electric-hydraulic push rod, featuring strong overload capacity, self-locking, and no leakage. It achieves the lifting and lowering of the plow blade by controlling the positive rotation of the motor.

2. The plow head is divided into a front section (alloy high-chromium manganese or asbestos) plow blade and a rear section (wear-resistant rubber plate) plow head, which ensures cleaner unloading.

3. The increased locking device on the plow head is a mechanical tension type, allowing for adjustable height of the plow blade to ensure a good surface contact with the belt. This design prevents the plow blade from lifting or shaking due to the impact force of coal during operation, thereby avoiding belt tearing, wear, and coal leakage. 4. The drive section's electro-hydraulic cylinder comes in two installation options: (1) the cylinder is placed above the coal separator, and (2) the cylinder is placed on either the left or right side of the coal separator, for user convenience. 5. The unloader's flap, specifically designed for gas-locking funnels, is made of high-chromium manganese material, (1) extending the service life to 20 years and reducing maintenance, (2) reducing induced aeration to less than 10% of the original amount, and (3) ensuring even material distribution, preventing spillage and sticking along the way.
