Coal ash transport separator for mining machinery DYTN-800 electro-hydraulic push rod unloader

Overview

This product is used for the segmented unloading of conveyors in mines, metallurgy, power plants, coal yards, collection stations, and port terminals. The hydraulic plow-type unloader is a mechanical product installed on the middle frame of a belt conveyor, responsible for unloading materials and controlling the flow and direction of material conveyance. It can evenly and continuously unload the conveyed materials into a hopper or the required location. This unloader features a variable slot angle, auxiliary plow blades, and has been upgraded to use an electro-hydraulic push rod as the power source, overcoming the shortcomings of the old-style unloader, such as incomplete plowing of materials, scraping the belt, poor overload capacity, frequent motor burnout, bending of screw threads, and easy mechanical damage.

2. Operating Principle

Type single or double-sided plow-type unloading device, powered by an electro-hydraulic push rod. During operation, the push rod extends to drive the linkage, advancing the frame to lower the head and support the flat roller assembly, ensuring the belt working surface is flat. The lower edge of the head is tightly sealed to the belt surface, depositing the material onto the hopper and delivering it to the designated location. After unloading, the electro-hydraulic push rod retracts to pull back the linkage, causing the frame to retreat, lifting the plow head. The roller assembly transitions from parallel to trough shape, allowing the material to pass smoothly. (The principle of the electro-hydraulic push rod is explained in the linkage section.)

1. The power source drive section is a dual-purpose hand torch hydraulic electro-hydraulic push rod, overcoming the shortcomings of electric push rods (poor overload capacity, motor burnout, screw bending) while preventing jamming, and maintaining the advantages of electric push rods (no leakage, self-lubricating). It achieves the lifting and lowering of the plow head through controlling the motor's forward and reverse rotation. 2. The plow head is divided into a front section (alloy manganese or asbestos material) and a rear section (rubber plate), making unloading cleaner. 3. The added tensioning device for the plow head is a mechanical tensioning type, which can adjust the height of the plow blade, ensuring the blade is flush with the belt during operation, preventing the plow blade from lifting or shaking due to the impact force of coal, thus avoiding belt tearing, wear, and coal leakage. 4. The electro-hydraulic push rod in the drive section comes in two installation options: (1) the push rod is placed above the coal separator; (2) the push rod is placed on the left or right side of the coal separator, for user convenience. 5. The flip gate of the unloader's gas lock hopper is made of high-chromium manganese material: (1) extending service life to 20 years, reducing maintenance; (2) reducing induced air draft to below 10% of the original amount.3) Ensure material evenness to prevent spillage, sticking, and material loss along the way.
