Scrape coal cutting edge 1 and layer board 2 and can do the motion that is close to each other or keeps away from each other under transmission's effect, when scraping coal cutting edge 1 and layer board 2 and be close to each other, layer board 2 holds up coal conveyor belt working face 101, scrapes the upper surface of coal cutting edge 1 butt at coal conveyor belt working face 101, along with the motion of coal conveyor belt, accomplishes the cleaning to gluing, freezing coal.

The both sides of coal conveying belt are equipped with support 202, the below of coal conveying belt is equipped with relative chassis 203 that sets up, transmission is including establishing electric putter 3 on one side chassis 203, it is equipped with transmission shaft 4 rather than the fixed connection with support 202 rotation to pass both sides support 202, the end of transmission shaft 4 is equipped with rather than fixed connection's first transmission pole 5, the end fixed connection of first transmission pole 5 and electric putter 3, be equipped with on the transmission shaft 4 rather than synchronous pivoted triangle steel frame 6, fixed being equipped with on the hypotenuse of triangle steel frame 6 scrapes coal cutting edge 1, through the flexible of electric putter 3, drive first transmission pole 5 and rotate and then make transmission shaft 4 take place to rotate, the fixed square frame 15 that is equipped with in transmission shaft 4 upper portion, the both sides and the support 202 of triangle steel frame 6 rotate to be connected, and be connected with square frame 15 through pull rod 16, the rotation of square frame 15 drives triangle steel frame 6 through pull rod 16 and rises or falls, and then can drive and scrape coal cutting edge 1 and accomplish the motion of rising and whereabouts.

The transmission shafts 4 on the inner sides of the two supports 202 are respectively and fixedly provided with a second transmission rod 7, the tail ends of the second transmission rods 7 are fixedly connected through a connecting rod 8, the connecting rod 8 is fixedly sleeved with two bent rods 9, the other ends of the two bent rods 9 are respectively hinged with the two sides of a bracket 201 used for placing the supporting plate 2, connecting handles 10 are further hinged to the two sides of the bracket 201, the other ends of the connecting handles 10 are hinged with the bottom frames 203 on the two sides, the first transmission rod 5 is driven to rotate through stretching of the electric push rod 3, so that the second transmission rod 7 on the transmission shafts 4 rotates, meanwhile, the connecting rod 8 between the second transmission rods 7 moves, force is transmitted to the bracket 201 through the bent rods 9 connected with the connecting rods 8 and drives the bracket 201 to move back and forth, and the supporting plate 2 is lifted up or falls down through the connecting handles 10 respectively hinged with the bracket 201 and the bottom frames 203 when the bracket 201 moves back and forth.

As shown in fig. 2 and 3, in order to prevent the coal scraping blade 1 from excessively contacting the upper surface of the coal conveying belt working surface 101, a limiting device is arranged right below the end of the coal scraping blade 1, the limiting device comprises a fixing rod 11 and a vertically arranged bolt 12 positioned at the top of the fixing rod 11, the bolt 12 is in threaded connection with the fixing rod 11, the height of the whole limiting device is adjusted by rotating the bolt 12, and the coal scraping blade 1 is prevented from continuously falling when contacting the top of the bolt 12 in the falling process of the coal scraping blade 1.

The side of the coal conveying belt close to the tail end of the coal scraping blade 1 is provided with a blanking plate 13, sticky and frozen coal scraped by the coal scraping blade 1 slides down through the blanking plate 13, and then leaves the working surface of the coal conveying belt. One side of the coal scraping blade 1 close to the blanking plate 13 is provided with a baffle plate 14 for assisting the scraped sticky and frozen coal to enter the blanking plate 13. The end of the blanking plate 13 is also provided with a conveyor belt (not shown) for returning the scraped coal to the coal yard.

The working and using processes are as follows:

the coal scraping blade and the supporting plate are relatively close to each other:

taking the angle shown in fig. 4 as an example, the electric push rod 3 is retracted, the first transmission rod 5 rotates counterclockwise to drive the transmission shaft 4 to rotate counterclockwise, the second transmission rod 7 positioned on the transmission shaft 4 also rotates counterclockwise, and meanwhile, the square frame 15 fixedly connected with the transmission shaft 4 moves downward, so that the triangular steel frame 6 falls down under the action of the pull rod 16, and the coal scraping blade 1 positioned on the triangular steel frame 6 also completes the descending process;

when the second transmission rod 7 rotates anticlockwise, the connecting rod 8 drives the curved rod 9 to move towards the right side, after the bracket 201 is pulled rightwards, as the two ends of the connecting handle 10 are respectively hinged with the bracket 201 and the underframe 203, the connecting handle 10 is gradually changed from a state close to the horizontal state to a state close to the vertical state, so that the bracket 201 is lifted up to drive the supporting plate 2 to move upwards; the process of the coal scraping blade 1 descending and the process of the supporting plate 2 ascending are synchronously carried out, so that the coal scraping blade 1 is abutted to the upper surface of the coal conveying belt working surface 101.

The coal scraping blade and the supporting plate are relatively far away:

the process of keeping away from relatively is opposite with the process that above-mentioned is close to relatively, does not carry out here too much and gives unnecessary details, when need not scrape the coal cutting edge and scrape the coal, electric putter extension can accomplish and scrape the process that coal cutting edge and layer board kept away from relatively.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications or substitutions do not depart from the scope of the invention in its corresponding aspects.
