[0002] In the pellet production process, the pellet roller screen as the key equipment, its screening efficiency directly influences the actual production capacity of pellet line. However, the traditional pellet roller screen often faces the problem of serious material sticking of screen roller in the material distribution process, which leads to a large number of qualified balls unable to be effectively screened, and returns to the balling system with unqualified balls, which not only reduces the screening efficiency, but also increases the product unit consumption, reduces the pellet quality, and brings great challenges to the pellet production. Although there are some cleaning devices on the market, there are still problems such as complex structure, difficult maintenance, and unsatisfactory cleaning effect.

[0003] CN108421692A discloses a kind of screen roller automatic cleaning device, including angle steel, wheel, cleaning unit and oil pump;The angle steel is set in the upper of the screen roller automatic cleaning device;The wheel is set in the two ends of the angle steel;The cleaning unit is set in the middle position of the angle steel;The oil pump is connected with the cleaning unit;The lower side of the angle steel is also vertically provided with several reinforcing bars;The reinforcing bar is located at the two sides of the screen roller;Through the reciprocating action of hydraulic cylinder, cleaning unit is pushed to complete cleaning action. Automatic cleaning of sundries between screen roller, greatly reduce the burden and maintenance intensity of post worker.

[0004] But the above design needs to increase additional hydraulic cylinder, increases additional power source, and the transformation cost is high, and the maintenance cost is high. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a kind of big ball roller screen automatic cleaning device to solve the problem of serious material sticking of screen roller, high transformation cost and high maintenance cost.

[0006] To achieve the above purpose, the basic scheme provided by the utility model is as follows: a kind of big ball roller screen automatic cleaning device, including first sliding groove and cleaning brush, the cleaning brush includes slide bar and cleaning rod, the slide bar is parallel with big ball roller screen, the cleaning rod is fixed on slide bar by hardware fixture, the two ends of slide bar are slidably connected with first sliding groove, the slide bar is connected with traction frame, and the traction frame is connected with swing head belt machine.

[0007] The utility model discloses a principle and beneficial effect lies in: the swing head belt conveyor is located above big ball roller screen, and its swing range can cover entire big ball roller screen, and can be by the swing action of swing head belt conveyor, and reciprocating motion is drawn in the first sliding slot, and the automatic cleaning of big ball roller screen is completed.

[0008] Scheme two, this is the preferred basis scheme, the cleaning brush has two, and the cleaning brush is connected in the both sides of swing head belt conveyor through the traction frame. The operation of swing head belt conveyor is swing, and the dead angle of cleaning can be left, and two groups of cleaning brushes can cover more comprehensively, and clean more cleanly.

[0009] Scheme three, this is the preferred basis scheme, and the both sides of swing head belt conveyor are equipped with the second sliding slot, and the sliding block is slidably connected in the second sliding slot, and one end of traction frame is rotatably connected with the slide bar through the pin, and the other end of traction frame is fixedly connected with the sliding block. Swing head belt conveyor does swing reciprocating action, and cleaning brush does parallel reciprocating action, so that the connection of traction frame and slide bar can rotate at a certain angle, and the connection of traction frame and swing head belt can slide at a certain distance, to prevent the deflection of slide bar in the movement process.

[0010] Scheme four, this is the preferred basis scheme, and the number of cleaning rods is same with the gap number of big ball roller screen, and the interval of adjacent cleaning rods is equal with the interval between adjacent roller screen shafts. Each cleaning rod extends into the gap between adjacent two roller screens, and reciprocating motion is cleaned rod while the roller screen rotates, and the material on the roller screen is scraped.

[0011] Scheme five, this is the preferred basis scheme, and the both ends of slide bar are rotatably connected with the pulley, and the first sliding slot is equipped with the guide rail, and the pulley is movably connected with the guide rail. The pulley moves in the guide rail, and further limits the parallel reciprocating motion of slide bar between the first sliding slot, to prevent the deflection of slide bar.
