Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
As depicted in figs. 1 and 2, coal pulverizer of the present utility model comprises frame 1, is provided with housing in frame 1, and housing is made up of the upper shell 2 be connected up and down and lower house 3; Housing central section is provided with fore bearing parts and rear bearing parts;
Forward and backward parts of bearings structure is identical, includes the bearing block 5 be arranged in housing and frame, is provided with rotating shaft, axle in bearing block 5 by bearing 19
holdoutside is provided with bearing (ball) cover 4; Rotating shaft in fore bearing parts is front rotary shaft 6, and the rotating shaft in rear bearing parts is rear rotating shaft 7;
The inner of the rotating shaft of forward and backward parts of bearings is connected to forward wheel disc 8 and rear runner dish 9, is connected with some shock posts 10 between forward and backward runner dish 8,9, and each post 10 that clashes into circumferentially evenly is arranged at forward and backward runner dish 8,9 radially outer edge place;
Front rotary shaft 6 or rear rotating shaft 7 are connected with belt pulley 11, the circular radial side face of belt pulley 11 are interval with some roads (preferably 3 roads) for strengthening the groove 12 of the frictional force between belt, make the utility model be suitable for using V-shape belt.
Housing upper is connected with feed pipe 13, and housing bottom is connected with discharge nozzle 15; The open top of feed pipe 13 arranges and forms charging aperture 14, and uncovered setting the in the bottom of discharge nozzle 15 forms discharging opening 16.
Particularly, the left socle 17 that described frame 1 is connected by left and right and right support 18 form, so that assembly and disassembly.Described bearing (ball) cover 4 is connected between left socle 17 and right support 18; Described shock post 10 is circumferentially evenly connected with 8 between forward and backward runner dish 8,9; Described feed pipe 13 is connected to upper shell 2 top, and described discharge nozzle 15 is connected to the bottom of lower house 3.
Described feed pipe 13 is positioned at housing rear portion, and described discharge nozzle 15 is positioned at housing front portion, and described feed pipe 13 is inclined upwardly setting backward, the downward-sloping setting forward of described discharge nozzle 15.
Such setting, on the one hand makes coal cinder need in the housing to move to front lower place by rear on, thus extend coal cinder by the path of housing, strengthen broken probability and crushing effect, another aspect is convenient to charging and discharging.
During work, the shock post 10 that wearing and tearing are comparatively serious can be changed as required.Use driving belt connects the belt pulley (motor and belt pulley thereof are routine techniques, and figure does not show external motor and belt pulley thereof) in the rotating shaft of belt pulley 11 of the present utility model and external motor.Start external motor, driving belt drives front rotary shaft 6 or rear rotating shaft 7 to rotate by belt pulley 11, and then front rotary shaft 6 or rear rotating shaft 7 drive forward and backward runner dish 8,9 and shock post 10 therebetween to rotate.Gathering coal enters housing from the feed pipe 13 at top, being clashed into by the shock post 10 in being rotated by 8 during housing, broken, thus forms fritter coal.Fritter coal after fragmentation flows out the utility model by discharging opening 16.
Maintenance of the present utility model
1. before using, this device of reply main portions is cleared up;
2. should regularly to this assembly axis and bearing 19, bearing block and bearing 19 carry out lubricated;
3. after using, a few minutes should be dallied to use next time.
Points for attention
1. frame 1 should be fixed on the ground before using, in order to avoid V-shape belt loosens after starting;
2. when using avoid hand to stretch into charging aperture, try one's best away from V-shape belt in order to avoid scratch;
3. the coal cinder being greater than charging aperture should be avoided to send into charging aperture 14, in order to avoid cause blocking phenomenon.
Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although be described in detail the utility model with reference to above-described embodiment, those of ordinary skill in the art is to be understood that: still can modify to the utility model or equivalent replacement, and not departing from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of right of the present utility model.
