The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is by main shaft 1, floral disc 3, compositions such as grinding roller 16 and body 18, body 18 is divided into upper machine body 10, middle body 8 and 9 three parts of base, and base 9 is installed on the basis by bolt, and its inwall is provided with abrasion-proof backing block 17, within the abrasion-proof backing block 17 the wall bus be vertical line or and ground inclination, inner wall surface can be shiny surface or make the band serrate slot non-shiny surface.In body 8 is upper and lower connects respectively with upper machine body 10 and base 9 by bolt, which is provided with a window, be convenient to inspection, adjustment and oiling.Upper machine body 10 is provided with charging aperture, and bearing block 2 is connected on the upper machine body 10, is provided with bearing in it.Main shaft 1 is contained on the bearing block 2 by bearing, bearing cap etc., can rotate under the drive of motor, and floral disc 3 is fixed on the main shaft 1 by key and nut, is arranged in body 8, establishes a spreading disk 11 on it.When main shaft 1 rotation, spreading disk 11 and floral disc 3 rotation synchronously under it drives.On floral disc 3, offer two or two above holes at least, one hinge 5 is installed in the hole; rocking arm 13 1 ends and hinge 5 are hinged; can rotate around hinge 5 center lines; grinding roller 16 is contained in the other end of rocking arm 13; the two keeps position relation in relative rotation by bearing, promptly grinding roller 16 both can rotate around hinge 5 center lines under the drive of rocking arm 13 again around self axis rotation.For improving friction between grinding roller 16 and abrasion-proof backing block 17 inwalls, to be convenient to material and to enter, the inner wall surface of grinding roller 16 outer walls and abrasion-proof backing block 17 can be processed into the non-shiny surface of being with serrate slot etc.For restriction grinding roller 16 outwards move; rocking arm 13 outer walls are established special 131; be fixed on adjustment seat 6 on the floral disc 3, adjust the formation stopping means such as adjusting lever 7 that are provided with on the seat 6; can adjust 17 best clearance when no material enters of grinding roller 16 and abrasion-proof backing block, avoid the direct collision between grinding roller 16 and abrasion-proof backing block.During grinding material, grinding roller 16 can be done inwardly motion to main shaft 1 centerline direction, and outwards motion then is restricted, and makes it both have certain tolerance, can reach best crushing effect again.
In the present embodiment, floral disc 3 also offers groove, and spring 4 one ends place in the groove, and the other end places on the spring base 12, and this spring base 12 is connected with main shaft 1 by pretension screw rod 14.In spring base 12 bottoms, establish a protruding axle 15, this protruding axle 15 is arranged at wall outside the rocking arm 13, can transmit and bear the active force of spring 4.Above-mentioned spring 4, spring base 12, pretension screw rod 14, the protruding axle 15 etc. that is arranged at wall outside the rocking arm 13 have constituted elastic device 19.
The utility model, spring 4 can adopt metal or nonmetallic materials, and its shape can be various ways such as stage clip, extension spring, torsion spring, also can be hydraulic spring grease cup or gas spring, can also to each rocking arm 13 spring be set separately according to the structure needs.
During work, thereby main shaft 1 drives spreading disk 11, floral disc 3 rotates rotor parts such as rocking arm 13, grinding roller 16 synchronously.When material did not enter, rocking arm 13 was limited by stopping means, made between grinding roller 16 and the abrasion-proof backing block 17 to keep certain interval.After material enters from A, spread wall within middle body 8 by spreading disk 11, fall to entering wall within the abrasion-proof backing block 17 at gravity effect lower edge inwall, 16 of grinding rollers under frictional force and the material drag effect with rocking arm 13 outside wall produce relative rotation, thereby roll material, grinding pressure then is making a concerted effort of being formed by stacking of centrifugal force and acting force of the spring, change rotating speed or adjustment spring force can be adjusted grinding power size easily, under some situation, also can be without spring, only by centrifugal action.By the material of grinding, discharge from discharging opening B.Blanking velocity, thickness of feed layer and product grade constitute and can control by the influence factors such as flow velocity of the gap length material outlet between angle, grinding roller 16 and the abrasion-proof backing block of abrasion-proof backing block 17 inwalls.
