Abstract
The utility model discloses a roll coal screening machine, which comprises a frame, a hopper arranged on the frame, and a spiral propeller arranged at the bottom of the hopper. A discharge hole of the spiral propeller joins with a feeding hole of a tilt cylindrical shaped screen. The end part of the feeding hole of the cylindrical shaped screen is provided with a baffle preventing the cylindrical shaped screen from falling down. The cylindrical shaped screen provided with a gear ring on the outerwall is arranged on a riding wheel, the gear ring of the cylindrical shaped screen meshes with a gear wheel, a gear shaft connects with an output shaft of a driving motor by a transmission, and a dustproof sealed cover is arranged outside the cylindrical shaped screen. The utility model has the advantages that the coal screening quantity is large, the screen hole is not easy to be blocked, the work operation is reliable, the maintenance and the overhaul are quite convenient, the energy consumption is lower, the floor occupation area is small, the supporting facilities are less, the pollution to environment is light, and the move is relative convenient, etc.
Description
Technical field
The utility model relates to a kind of screened coal device, especially relates to a kind of rolling machine of screening coal.
Background technology
At present, the machine of screening coal on the market mostly is gravity flow screen and plane reciprocating sieve greatly, the gravity flow screen that now is used for coal yard or boiler room is that its inclination is positioned on the streamline of screening coal, the coal downslide of rolling on tilting gravity flow screen, reach the screening purpose, but the coal particle under the sieve is inhomogeneous, sieve aperture stops up easily.Plane vibration sieve is to tilt to be placed on the breeching equally, by vibrator coal is moved reciprocatingly on sieve, realizes the purpose of screening coal, and its floor space is big, and sieve aperture also easily stops up, and because of vibrating coal dust is flown upward, and working environment is polluted.Chinese patent CN 87208850U discloses a kind of rolling machine of screening coal, overcome above-mentioned defective to a certain extent, but the rotating shaft rotation that the rotation of its drum sieve relies on motor-driven to be installed on its axial centre position drives, power consumption is big, break down easily, mainteinance repair is quite inconvenient, needs supporting equipment many; And can not move.
The utility model content
The purpose of this utility model is to overcome the defective of the existing machine of screening coal, and provides a kind of sieve aperture to be difficult for stopping up, the efficient of screening coal height, and energy consumption is lower, the rolling that operation troubles the is few machine of screening coal.
Further purpose of the present utility model is to provide a kind of building ring is polluted the light rolling machine of screening coal.
Further purpose of the present utility model is to provide a kind of rolling of conveniently moving machine of screening coal.
The purpose of this utility model is achieved through the following technical solutions: it comprises frame, rack-mounted hopper, feed hopper bottom is provided with spiral propeller, the spiral propeller discharging opening is connected with the charging aperture of tilting drum sieve, the charging aperture end of described drum sieve is provided with the baffle plate that prevents that drum sieve from gliding, the drum sieve that outer wall is equipped with gear ring places on the support roller, a gear ring on the described drum sieve and a gears engaged, and described gear links to each other with the output shaft of drive motors by speed changer.Preferred version: drum sieve tilt adjustable.
Drum sieve sieve aperture shape is not limit, preferred rectangle.Slot size is determined to decide according to producing needs.
Operation principle: the coal that will need to sieve is put into hopper, coal pushes hopper by spiral propeller, drive motors drives with drum sieve gear ring meshed gears by speed changer and rotates, gear drives the drum sieve rotation again, because drum sieve rotates, coal rolls in screen drum, will pass sieve aperture less than the coal of sieve aperture and fall, lump coal greater than sieve aperture is then discharged along the screen drum outlet, finishes the screen classification thus.
The further purpose of the utility model is achieved through the following technical solutions: on the basis of such scheme, have additional the dust seal cover outside drum sieve.
The utility model further purpose is achieved through the following technical solutions: the machine of screening coal of the above scheme is installed on movably on the chassis (for example automobile chassis, go-cart chassis etc.).
It is big to the utlity model has the amount of screening coal, and sieve aperture is difficult for stopping up, reliable working operation, and mainteinance repair is convenient, and energy consumption is lower, and it is little to take the ground area, and auxiliary facility is few, and environmental pollution is light, moves advantages such as more convenient.
Description of drawings
Fig. 1 is for being the structural representation of the utility model one embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to accompanying drawing: present embodiment comprises frame 12, be installed in the hopper 1 on the frame 12, hopper 1 bottom is provided with spiral propeller 2, the augering screw of spiral propeller 2 is installed on the bearing block 3, the discharging opening of spiral propeller 2 is connected with the charging aperture of tilting drum sieve 7, the charging aperture end of described drum sieve 7 is provided with the baffle plate 8 that prevents that drum sieve 7 from gliding, the drum sieve 7 that outer wall is equipped with gear ring 9 places on the support roller 11, gear ring 9 on the described drum sieve 7 and gear 10 engagements, the axle of described gear 10 links to each other with the output shaft of drive motors 5-2 by speed changer 4-2.The axle head of spiral propeller 2 links to each other with gearbox 4-1 by universal joint 6, and gearbox 4-1 links to each other with drive motors 5-1 by driving belt.The whole system of screening coal is installed on movably on the chassis 13.
