Description
Technical field
A kind of scraper lifting machine is the utility model is related to, the anti-feed back structure of more particularly to a kind of scraper lifting machine, is belonged to
Conveying equipment technical field.
Background technology
The scraper lifting machine in grease field at present, the scraper plate used is flat board, and scraper plate and flight chain are along the direction of motion
In angle necessarily backward, when position rotation is taken turns in lifting to the end, the material on scraper plate slides, and trickle feed inlet and outlet.Due to scraping
The downward inclination angle of plate is little, and material is had on scraper plate and has little time the feed inlet and outlet that trickles, remaining just as scraper plate goes to great wheel top
Material will be thrown to the back side passage of scraper plate, be returned to the bottom of scraper plate, so as to which by being recycled to top discharge, repetition disappears again
The energy of lifting has been consumed, it is low to cause transfer efficiency.And the reciprocation cycle of material can cause powder to increase, when some materials
When requiring fines content, it will be extremely difficult to require.
Utility model content
The purpose of this utility model is, overcomes problems of the prior art, there is provided a kind of scraper lifting machine is prevented
Feed back structure, the generation of material powders is reduced, transfer efficiency can be improved, reduce energy consumption.
For solve above technical problem, a kind of anti-feed back structure of scraper lifting machine of the present utility model, including housing and
Great wheel positioned at case top inner chamber, chain is surrounded with the great wheel, uniform intervals are connected with scraper plate on the chain, described
The feeding side of housing is provided with discharging opening close to the position of great wheel, and up chain is located in the feeding wing passage of housing, descending
Chain is located in the backhaul wing passage of housing, and the feeding wing passage and the backhaul wing passage are separated by channel partition, described
Scraper plate includes the scraper plate A sections and scraper plate B sections being mutually butted at an angle, advance of its middle scraper A sections perpendicular to the chain
Direction, the scraper plate B sections tilt backwards relative to the direction of advance of chain.
Relative to prior art, the utility model achieves following beneficial effect：When material is led to by scraper flight to feeding side
The top in road, due to the top of feeding wing passage and the lower edge of discharging opening is relative connects, up with the continuation of chain, on scraper plate
Material is slid and dished out from discharging opening, and because the inclination angle of scraper plate B sections is bigger, the positive material of scraper plate B sections can be all spilled over, scraper plate
The positive material of A sections largely can also be fallen, and a small amount of remaining material has little time to unload, and goes to great wheel above water, from scraping
Under the centripetal end of plate A sections is thrown.Relative to the monoblock flat scraper plate angled with chain, scraper plate of the present utility model, which is divided into, is in
Two sections of certain angle docking, when up, the extruding force that the material on scraper plate is subject to is smaller, and feed back is greatly reduced,
The fines content of material can be reduced.On the other hand structure of the present utility model so that the moment of flexure of chain and scraper plate pad is reduced, and is prolonged
The service life of chain and scraper plate is grown.
As improvement of the present utility model, the upper end of the channel partition is connected with the stock guide upwardly extended, described to lead
The top of flitch is provided with the stock guide avoidance elongated slot for avoiding the great wheel, and the two of great wheel is lateral described in the upper end edge of the stock guide
On extend to the postmedian of great wheel and rolled to backhaul oblique.On a small quantity from the material scraped under back is thrown, first edge in great wheel
Parabola falls the side towards discharging opening in stock guide, after shock deflecting dished out from discharging opening direction.By the transformation of scraper plate
With the water conservancy diversion of stock guide, enter backhaul wing passage without material substantially, feed back is greatly reduced, and can save 10%, extends scraper plate
With the service life of chain.
As further improvement of the utility model, the up chain corresponding with the discharging opening is along before up oblique line
Enter, the upper end of the up oblique line tilts to discharging opening side.Chain is more upward more is tilted to discharging opening direction so that scrapes
Plate increases to the inclination angle of discharging opening, is advantageously slid in material from scraper plate.
As further improvement of the utility model, the lower inner termination along plate of the discharging opening and the channel partition
Upper end is docked, and is tilted down along the external end head of plate under the discharging opening and angle of inclination and the material casting angle phase one of the stock guide
Cause.Be advantageous to material to be spilled over from discharging opening, will not be formed and be detained along plate under discharging opening.
As further improvement of the utility model, the scraper plate includes scraper plate push pedal and scraper plate wearing plate, the scraper plate
Push pedal is connected with the chain, and the scraper plate wearing plate covers and is fixed in the scraper plate push pedal and is located at where material
Side.Scraper plate push pedal and scraper plate wearing plate include two sections be mutually butted at an angle.
