The product further overcomes the midpoint of all the old unloaders, because it improves the device methods of three different structures, i.e., front and rear ploughs, locking device, hand-electric dual-purpose device and machine self-locking device, so as to be the advanced coal separator in China.

1. The plough head door is divided into front plough head made of alloy high chromium manganese or asbestos material and back plough head made of wear-resistant rubber plate to make discharge cleaner.

2. The locking device for plough head growth is machine-type grab-pull type. The height of plough knife can be adjusted to cut the belt with the best face. The plough knife will not rise or vibrate because of the impact of coal during the task, which prevents the belt from being torn, worn and leaking.

3. The driving department is the latest calculator in China, the electro-hydraulic push rod for hand-electric dual-purpose machine. It overcomes the shortcomings of poor overload ability of electric push rod, burnable motor, jamming, top bending screw rod and so on. General electro-hydraulic push rod surface leakage, non-self-locking, sliding, creeping and other new disadvantages. However, the electro-hydraulic push rod of the dual-purpose machine with flashlight has the advantages of self-locking, inner sealing, overloading, balanced operation, etc.

4. Installation method is divided into three kinds: a, B and C. Electro-hydraulic push rod can be placed on the upper part of coal separator, vertical device and tape side device, which greatly facilitates customers.

5. The high manganese wear-resisting material used in the flange of air lock extends the service life for 20 years and increases the maintenance quantity.

6. The application of the air-lock department can make the material evenly distributed, prevent deviation, sticking and spilling along the way.

7. Increase the temptation blast and make it accelerate to less than 10%.

8. It can be used for transporting adhesives, wet materials, bulk materials, powder materials and preventing sticking.
