Apron feeder are also used for the continuous and uniform distribution and transfer of material to crusher, conveyer, or other working machine in a horizontal or slanted direction.It is especially suitable for transporting bulk, high temperature and sharp materials, and can work reliably in the open air and in humid and harsh environments.
Apron feeders are generally classified as heavy, medium, and light feeders and are commonly used in concentrators.
The pitch is 228.6 mm (9 inches) high strength of bulldozer die forging chain for traction, two chain around installed in the head of a driven sprocket and body got behind a pair of tension wheel at the end of the closed loop, in every link of the two rows of chain on assembling the overlap each other, the transport of heavy structure slot as a continuous to carry material conveying line.The self-weight and the weight of the material are supported by the multi-row supporting wheel, chain supporting wheel and slide beam installed on the machine body.The transmission system is connected to the reducer by the AC frequency conversion speed regulating motor, and then the carrier mechanism is driven to run at low speed by the direct connection between the rising sleeve and the driving device.The material discharged into the tail bin is transported to the front of the body along the conveying line to achieve the purpose of continuous and uniform feeding to the working machinery below. The tensioning device adopts screw tensioning type
Tensioning support adopts section steel and bolt connection structure, appearance, beautiful, easy to assemble and disassemble.For heavy-duty and super-heavy-duty tensioning devices, add a set of springs to buffer vibration absorption.In addition, there are the following two characteristics:
(1) The screws of the medium and lightweight Apron Feeder tensioning devices are located above the slide seat and under the inverted equilateral Angle steel, and the screw portion is protected from contamination and damage;For heavy-duty and super-heavy-duty product tensioning devices, the screw passes through the center of the slide seat.
(2) the tension device is divided into standard type and heavy two kinds of structure, and with the bottom of the bucket elevator tension device to maintain serialization and generalization.The head and tail bearings are mostly made of rolling bearings. The head bearing seat is not supported on the frame horizontally, but is connected to the bearing seat vertically on the frame with four bolts.This on the one hand makes the bearing seat force and the direction of the work force consistent, improve the bearing seat and bolt force, on the other hand, reduce the space size.
Adopt combined sprocket
The driving sprocket wheel is made of cast iron or steel, and the wheel rim is made of high wear-resisting quenched steel into an exchangeable tooth structure.The gearing - less flange of the tensioned sprocket is combined and replaceable.This can reduce a lot of maintenance, reduce maintenance costs.In addition, the replaceable gearless rim can ensure the correct and constant contact between the chain and the sprocket, and prevent the tooth surface from gluing.
Backup roll wheel The medium and lightweight Apron Feeder support rollers are external and separate from the traction roller and have the following advantages :(1) Easy setting of the rail slot.(2) reduce traction roller wear.(3) easy to manufacture.For heavy and ultra-heavy Apron Feeder, fixed support rollers are provided on the frame.The lubrication of the roller and the head and tail bearing seats adopts the centralized oil supply mode to ensure regular and comprehensive lubrication.
Hydraulic coupler
A hydraulic coupling between the drive motor and the reducer ensures smooth starting and overload protection for the apron feeder.The chain drive is used between the reducer and the main shaft, which has the buffering effect, and can also make the transmission ratio stable, can transfer the high power, and the center distance is adjustable, which is easy to arrange and install.The drive shaft is equipped with a reverse stop device to prevent the reverse rotation of the conveying groove.In addition,
