A lot of details have been set forth in the following description so that make much of the utility model; But; The utility model can also adopt other to be different from other modes described here and implement, and therefore, the utility model is not limited to the restriction of following disclosed specific embodiment.
Embodiment one:
Fig. 1 to Fig. 4 shows the scheme drawing according to said clear device for coal one preferred embodiment of the utility model.Wherein, Fig. 1 shows the perspective view according to said clear device for coal one embodiment of the utility model; Fig. 2 shows structure shown in Fig. 1 and is installed in the structural representation in the slat conveyer; Fig. 3 shows the A-A of structure shown in Fig. 2 to cutaway view, and Fig. 4 shows the B-B of structure shown in Fig. 2 to cutaway view.
Extremely shown in Figure 4 like Fig. 1; The utility model provides a kind of clear device for coal; Comprise coal plate 1 clearly; Said clear coal plate 1 is installed on the both sides, cochain road of slat conveyer 100, leaves the gap between the driving surface 11 of said clear coal plate 1 and the scraper plate spigot surface 81, said driving surface 11 can scraper plate 8 through below the said driving surface 11 time with the retaining of the coal slime on the said scraper plate spigot surface 81 under.
Present embodiment is installed clear coal plate 1 through the both sides, cochain road at slat conveyer 100; Can clear up the coal slime of scraper plate surface adhesion effectively; Reduce scraper plate and brought down time coal that the chain road forms into; Thereby reduced the scraper chain running resistance, reduced the generation of chain rupture accident, also reduced the power consumption of slat conveyer.
As shown in Figure 1, preferably, said clear coal plate 1 also comprises the transition face 12 that is connected to said driving surface 11, and said transition face 12 is the wedge shape inclined-plane, and the rear and front end of said driving surface 11 is provided with said transition face symmetrically,
When said scraper plate 8 passed through the below of said clear coal plate 1, the gap between said transition face 12 and the said scraper plate spigot surface 81 reduced gradually;
When said scraper plate 8 moved to the said transition face 12 of rear end by driving surface 11, the gap between the said transition face 12 of said rear end and the said scraper plate spigot surface 81 increased gradually.
The two ends of clear coal plate 1 have the wedge shape inclined-plane, to guarantee that scraper plate 8 passes through smoothly, prevent when jumping the chain situation, and scraper plate 8 with clear coal plate 1 swipe takes place and impacts.
Have mounting hole 13 on the clear coal plate 1, be used to wear bolt 6.
It is easier for installation that two ends are provided with the structure on wedge shape inclined-plane symmetrically, need not distinguish inflow point and exit, and two ends have identical structure, can reduce scraper plate 8 and the impact swipe between the coal plate 1 clearly when taking place to jump chain to the full extent.
Certainly, clear coal plate 1 also can be provided with transition face 12 by an end at driving surface 11: said transition face 12 is the wedge shape inclined-plane, and during the said clear coal plate of said scraper plate 8 processes 1 below, the gap between said transition face 12 and the said scraper plate spigot surface 81 reduces gradually.
Can satisfy the requirement that scrapes coal slime fully like this, certain direction requirement is arranged when just installing.
Preferably, said clear coal plate 1 is installed on coal-ploughing board 3 through bolt 6.Like this, the Joint strenght between clear coal plate 1 and the coal-ploughing board 3 can be guaranteed, also clear coal operation can be accomplished better simultaneously.
Certainly, clear coal plate 1 can also adopt other modes to be installed on the coal-ploughing board 3, passes through welded and installed in said coal-ploughing board 3 like said clear coal plate 1; Said clear coal plate 1 is pasted on said coal-ploughing board 3.Adopt welding and powerful mode of pasting can clear coal plate 1 be fixedly mounted on the coal-ploughing board 3 equally.
Preferably, said clear coal plate 1 is installed on the biside plate of headstock 5 through bolt.As long as can clear coal plate 1 be fixed on the cochain road of slat conveyer 100, and the coal slime on the scraped scraper plate spigot surface 81 gets final product.Therefore, clear coal plate 1 can be arranged on the front end in cochain road, also can be arranged on the middle part or the afterbody in cochain road.
Preferably, said clear coal plate 1 adopts metal material to process.Because of will being in all the time, clear coal plate 1 scrapes the coal operating condition in the process of slat conveyer 100 work, so its work under bad environment, and work-hours is long; Therefore to select resistance to abrasion good; The metal material manufacturing that intensity is high can reduce the infringement of clear coal plate 1, avoids unnecessary replacing and maintenance.
Certainly, said clear coal plate 1 can also adopt resin material to process.The intensity of resin material is high, and resistance to abrasion is good, can accomplish the operation of clear coal slime well, and its density is little simultaneously, and material is lighter, can reduce the weight of slat conveyer complete machine.
Embodiment two:
To shown in Figure 4, the utility model also provides a kind of slat conveyer 100, comprises the clear coal plate 1 in the foregoing description like Fig. 2.
The principle of work of the slat conveyer 100 that present embodiment provides is following:
As shown in Figure 3, the cross sectional drawing of clear coal plate 1, its section form is identical with the space section that scraper plate 8, headstock 1, coal-ploughing board 3 threes form, and leaves certain clearance, guarantees that scraper plate 8 passes through smoothly.
As shown in Figure 1, the graphics of clear device for coal, clear coal plate 1 two ends have the wedge shape inclined-plane, pass through smoothly with assurance scraper plate 8, and the swipe impact takes place with clear coal plate 1 in scraper plate when preventing jumping chain situation.
Like Fig. 2, shown in Figure 3, clear coal plate 1 is installed in the both sides in head cochain road, the below of coal-ploughing board 3, is fixed on the coal-ploughing board 3 through bolt 6, and its lower surface (being driving surface 11) will have certain clearance with top (the scraper plate spigot surface 81) of scraper plate 3 both sides.
Like Fig. 3, shown in Figure 4; When scraper chain 4 carries coal cinder and coal dust through the side dumping head; Coal-ploughing board 3 can keep off the float coal of coarse coal and scraper plate upper surface down, and the float coal of scraper plate 8 both sides (scraper plate spigot surface 81) particularly sticks to the coal dust that is difficult for dropping on the scraper plate 8; Then can be scraped by clear coal plate 1, the coal that makes scraper chain 4 transported all falls into elevating conveyor and transports.
The clear device for coal that the utility model provides is simple in structure; Replacing, easy accessibility; Can effectively clear up the coal slime of scraper plate 8 surface adhesion, reduce scraper plate spigot surface 81 and brought down time coal that the chain road forms into, thereby reduced the running resistance of scraper chain 4; Reduce the generation of chain rupture accident, also reduced the power consumption of slat conveyer 100 simultaneously.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
