Description
Technical field
The utility model relates to the band conveyor of delivery of bulk material, further is meant the flat belt material scraping plate mechanism of ability automatically regulating material scraping plate to the applying power of belt conveyor.
Technical background
Band conveyor is mainly used in the delivery of bulk material.The aqueous ingredients that loose unpacked material has is big, have to contain the powder silt content big, these materials stick on the belt in course of conveying unavoidably, cause unload in the place of this discharging unclean; The material that sticks on the belt is walked out discharge zone with belt again, and under the effect of the float force of course of conveying, random scatters below belt feeder at the gravity of material own and belt.Material had both been wasted in this spreading, and contaminated environment again increases the work that a large amount of cleaning belts below scatters material simultaneously again, and therefore, band conveyor all is furnished with multi-form material scraping plate basically and scrapes clearly discharge port and stick to the material on the belt.
Traditional material scraping plate mechanism has alloy material scraping plate structure, rotary broom structure, rubber plate directly to scrape structure etc.Directly scrape the material scraping plate mechanism of structure; Be to increase a wear-resisting material scraping plate (antifriction rubber or epoxy resin board etc.) at belt conveyer driving wheel discharging position; Fit on the belt, belt transfers at driving wheel driving underspin and send material, and the material scraping plate that is attached on the driving wheel belt is motionless; When sticking to the material process wear plate on the rotation belt like this, just shoveled by wear plate.Can the applying power of material scraping plate and sports belt be bur is rooted out clean important parameter; The power of fitting simultaneously also is the basis that produces friction force between belt and wear plate; Applying power macrolesion belt; Applying power scuppit material is clean or be prone between belt and wear plate, embed hard material, as the direct scuffing belt of cutter.Therefore be transferred to applying power suitable and automatically the confining force weight range could not only shovel material totally but also guarantee belt life.
Therefore, develop ability automatically regulating material scraping plate and active belt applying power, reach effective cleaning and stick to the material above the flat belt, guarantee the mechanism of belt life again, necessary.
The utility model content
The technical matters that the utility model will solve is; Deficiency to the prior art existence; Design a kind of flat belt material scraping plate mechanism of ability automatically regulating applying power; Its utilization lever principle and spring performance realize automatically regulating material scraping plate and active belt applying power, can effectively clean the material that sticks to above the flat belt, can guarantee belt life again; Mechanism structure is simple, Installation and Debugging are convenient.
The technical solution of the utility model is; The flat belt material scraping plate mechanism of said ability automatically regulating applying power comprises frame and the material scraping plate group that is installed in belt discharge roll position; Said material scraping plate group has upper limb to be fitted in the material scraping plate on the feeding belt; Its constructional feature is; The bottom of this material scraping plate is installed on the buttress bracing struts through fastener, and the lower end captive joint of each same oscillating axle of two ends of this buttress bracing struts, said oscillating axle are hinged on supporting arm front end and hinge axes and the belt discharge roll parallel axes that is connected with frame; Be fixed with thrust axis back plate on the frame corresponding to said oscillating axle; One end is after the thrust axis of major part passes the axis hole of thrust axis back plate and passes the radially axis hole on oscillating axle top; The other end in thrust axis is loaded onto double nuts, and the major part of thrust axis one end is positioned at the thrust axis back plate outside; Be set with the stage clip between thrust axis back plate and oscillating axle on the thrust axis, the axis of the radially axis hole on oscillating axle top is vertical with the said hinge axes of this oscillating axle.
Below the utility model made further specify.
Said buttress bracing struts can be girder construction or elongated plates structure, also can be other suitable structures.
Said material scraping plate is preferably selected the not sticking material material that has enough rigidity and wear resisting property in the prior art for use, or selects the structure that has enough rigidity and wear resisting property in the prior art for use.
The principle of design of the utility model is, material scraping plate 8 to be fixed on the buttress bracing struts 16 design pair of swing axle 13 on the buttress bracing struts referring to Fig. 3; Like Fig. 2, oscillating axle 13 is hinged on supporting arm 19 front ends (the quite fulcrum of lever) that are connected with frame through jointed shaft 18, and oscillating axle 13 upper ends are connected (the quite active force of lever) on the thrust axis 3 that is set with stage clip 4; Thrust axis 3 one ends are fixed on the belt feeder frame motionless, and the other end and oscillating axle 13 link, a stage clip 4 double nuts 5 spacing location of screwing on again on the intermediate sleeve, and thrust axis 3 just can only move at compression spring 4 and 5 trace of locking double nuts like this; According to the characteristics of stage clip, have only stage clip to be compressed, the material scraping plate oscillating axle could rotate.The rotation of oscillating axle is just spacing like this, can only rotate in a direction, and is compressible during contraction, but stage clip is given restoring force that sets back of oscillating axle again.Through the position-adjustable material scraping plate of adjusting thrust axis double nuts and the applying power between belt.When applying power is transferred to when suitable, the locking thrust axis guarantees that applying power is stable.When making belt, the reason of chance promotes material scraping plate outward around the jointed shaft rotation of oscillating axle; Make it to reduce, cooperate material scraping plate to rotate thereby drive the thrust axis elongation, but thrust axis is spacing at prolonging direction with belt applying power; Can not extend again; It is constant that stage clip is given the power of oscillating axle like this, disappears in case belt promotes the power of material scraping plate, and material scraping plate sets back.
Referring to Fig. 3, after stage clip 4 is spacing, the thrust axis supporting, 2 with the distance of oscillating axle 13 be L, L also is the length after stage clip is compressed.After in case L is locked, the spring usable length can only≤L.Belt is F1 to the power of material scraping plate 8 at work, and F1 is decomposed into F11 and F12, and it produces moment of rotation M1, M1=F11*h11+F12*h12 to material scraping plate 8; Stage clip compression back produces the power F2 that promotes the material scraping plate S. A., and the moment that F2 produces is M2, M2=F2*h2.M1=M2 in the work.Fig. 1 will follow following rule: L according to selected stage clip and deciding to several sizes of Fig. 4, and h2 is big as far as possible, and h11 does not interfere according to material scraping plate width and scantling of structure and decides, and h12 reduces to reduce moment M1 as far as possible.
Know by above; The utility model is a kind of flat belt material scraping plate mechanism of ability automatically regulating applying power; Its utilization lever principle and spring performance realize automatically regulating material scraping plate and active belt applying power, can effectively clean the material that sticks to above the flat belt, can guarantee belt life again; Mechanism structure is simple, Installation and Debugging are convenient.
