Background technology
Apron conveyer be it is a kind of using haulage chain as haulage gear, dissepiment as bogey flexible traction continuity
Conveying equipment.During work, by transmission device drive head device sprocket wheel rotate, the chain being meshed with sprocket wheel also therewith to
Preceding motion, the hopper being also secured on chain and its back-up roller wheel also synchronously travel forward along the track in frame；Work as thing
After material adds hopper in charging aperture, discharging opening is transported to the mobile material of hopper, in the common of gravity and centrifugal force
Under effect, material unloads from discharging opening, into next process.
In existing apron conveyor structure, the tension effect of its tail-pulley device is not fine, it is often necessary to is tensed
It is fixed, the normal trouble-free operation of conveying is kept, so, existing tail-pulley device is improved, one kind is designed and more meets this
The take-up device of tail-pulley device structure, make the tension effect of the tail-pulley device more stable, more reasonable structure is practical.
Utility model content
The utility model discloses a kind of more preferable tail-pulley device of tension effect, and its main purpose is to overcome existing skill
Art above shortcomings and shortcoming.
The technical solution adopted in the utility model is as follows：
A kind of more preferable tail-pulley device of tension effect, including rotary shaft, left and right two biographies are symmetrically arranged with the rotary shaft
Movable sprocket, the rotary shaft both ends on the outside of two drive sprocket are respectively cooperating with being equiped with a strainer device, the driving-chain
Mounting hole is offered in the middle part of wheel, a neck is offered on the madial wall of the mounting hole, coordinates active card to be provided with one in the neck
Clamping key, be further opened with a fixing hole on the drive sprocket, the fixing hole be arranged in the drive sprocket and with the installation
Hole is connected, and coordinates fixation to be equiped with fixing bolt in the fixing hole.
Further, the strainer device includes strainer body and cooperation removable cover is located at the lid of the strainer body
Body, a stretching screw and a braking sleeve are vertically equiped with the strainer body, the braking sleeve is flexibly connected
The upper end of the stretching screw is installed in, coordinates in the braking sleeve and has been slidably installed with a sliding shoe.
Further, a lubricating cup body is also equiped with the strainer body, the lubricating cup body by a connecting tube with it is described
Braking sleeve is connected.
Further, the stretching screw bottom is arranged with the fixing nut of an adjustable elasticity.
Further, fixation is equiped with two trip bolts symmetrically installed respectively for the upper and lower part of the strainer body.
By above-mentioned to description of the present utility model, compared to the prior art, the utility model has the advantage of：
The utility model allows the tail-pulley device preferably to adjust and tense rotary shaft by setting strainer device,
The drive sprocket in rotary shaft and the chain on the drive sprocket is preferably adjusted and is tensed, make apron conveyor
Structure can more stably transmit operation, be more beneficial for the steady conveying of material.The utility model is rational in infrastructure simple, novel in design
Uniqueness, while there is preferable practicality, possess higher practical application and promotional value.
