dynamic pressure plate

05 and 07 working clearance of fixed pressuring plate is provided with feed appliance 09, described feed appliance 09 is positioned at discharging opening 101 places of the vibrating feed box 10 that is arranged on the frame 01, the working surface of described cam 041 is provided with the strip projection 0411 radially vertical with cam, each point on the described strip projection 0411 top outline line is walked upwards to be linear apart from the distance of place cam center of rotation axis and to increase or reduce of this outline line, and the shift fork 111 of described pull-fork assembly 11 is connected with described cam pack 04.

Power set 02 in the present embodiment comprise motor 021 and worm speed reducer 022.The utility model spy will be referred to as power set for main shaft provides prime mover of power or prime mover and transmission device.Cam pack of the present utility model can only comprise a cam, in this case, only needs the cam in the present embodiment is extended axially, and will extend axially with the cam mating part on the main shaft, cam can be endwisely slipped along main shaft get final product.In the present embodiment, main shaft is six prismatics at the cross section with the cam cooperation place, and this structure both can make cam rotate with main shaft, and cam is slided on main shaft, and this is the function that cooperates required realization of the utility model main shaft and cam just.Pull-fork assembly of the present utility model can only comprise a shift fork.

Two fixed pressuring plates of the present utility model and described dynamic pressure plate are obliquely installed Face to face on frame, the broken working clearance is that the gap between dynamic pressure plate and fixed pressuring plate is down " eight " font, be beneficial to nut like this and enter the broken working clearance from feed appliance, simultaneously, the nut of different sizes may be stuck on the diverse location of broken working clearance, has reduced less relatively nut and has leaked the probability of broken working clearance.For making nut be stuck in the broken working clearance reliably, the application of force when being convenient to fragmentation, the preferred matsurface of broken working face of described dynamic pressure plate and fixed pressuring plate in the present embodiment, is horizontally arranged with the striped of profile of tooth on the broken working face of dynamic pressure plate and fixed pressuring plate.

Described cam pack 04 comprises two cams 041 at least, and the connecting portion that adapts with shift fork 111 is arranged on the cam pack 04.When cam pack includes only two cams, the connecting portion that adapts with shift fork on the cam pack is arranged on the cam, two cams all are connected with shift fork, and two cams can be connected respectively with two shift forks in the present embodiment, also can connect with a shift fork that can be connected two cams; When cam pack also comprised miscellaneous part, as the pipe fitting in the present embodiment, the connecting portion that adapts with shift fork on the cam pack also can be arranged on the miscellaneous part.

Preferably, described cam pack 04 is made up of one section pipe fitting 042 and two cams 041 that are fixed on pipe fitting 042 two ends, on one of them cam 041 connecting portion that adapts with shift fork 111 is arranged.

Preferably, described pull-fork assembly 11 comprises shift fork 111 and the threaded adjusting axle 112 that is arranged on the frame 01, described shift fork 111 is provided with the thread connection portion that the threaded portion 1121 with threaded adjusting axle 112 screws, and an end of described threaded adjusting axle 112 is equipped with a handwheel 113.In the present embodiment, the threaded joints on the described shift fork is one to be embedded in the thread bush in shift fork one through hole, also can directly offer screwed hole on shift fork.

Preferably, there is a circular arc opening struck side of described shift fork 111, on the described threaded adjusting axle 112 plane bearing 114 is installed, and the DNA releaxed circular DNA of described plane bearing 114 contacts with frame 01.In the present embodiment, when rotating handwheel, plane bearing has the effect that the threaded adjusting axle rotates that is beneficial to.

For more easily to shift fork location, described pull-fork assembly 111 comprises that further one is arranged on the optical axis 115 on the frame 01, and described optical axis 115 passes on the shift fork 111 through hole and matched in clearance with it, and described optical axis 115 is parallel with threaded adjusting axle 112.In the present embodiment, on the through hole of the shift fork that optical axis passes, be inlaid with a sliding bearing, but also stringing bearing or common sliding sleeve.

Further, the nut cracker of the utility model embodiment also comprises the feed hopper 12 that is arranged on vibrating feed box top, be arranged on the outer machine shell 13 of frame, be arranged between dynamic pressure plate and fixed pressuring plate broken working clearance below and extend to the outer discharge bucket 14 of machine shell, be arranged on the ratchet 15 of feed appliance one end, be eccentrically set on the main shaft two ends and promote described ratchet and make feed appliance do push rod 16 with the step motion of main shaft interlock, be arranged on the stop device 17 that feed appliance reverses that prevents of the feed appliance other end.

Operation principle of the present utility model is: nuts such as walnut enter the vibrating feed box, under the vibration of vibrating feed box bottom vibrator, enter feed appliance, unify feeding by feed appliance, the power set drive shaft is rotated, and the cam on the drive main shaft rotates, cam promotes dynamic pressure plate, the nuts such as walnut of discharging from feed appliance fall into and are stuck in the broken working clearance of falling " eight " font between dynamic pressure plate and fixed pressuring plate, when the point on the cam strip projection overhead pulley profile contacts with the compression zone of dynamic pressure plate, broken working clearance minimum between dynamic pressure plate and fixed pressuring plate, the housing of nuts such as walnut is crushed, when the point of eccentric throw minimum on the cam contour line contacts with the compression zone of dynamic pressure plate, dynamic pressure plate is withdrawn under the effect of return spring, broken working clearance maximum between this moment dynamic pressure plate and fixed pressuring plate, the nuts such as walnut that crushed housing go out from fragmentation work interstitial row.

When needs are regulated fragmentation during the working clearance, only need to rotate handwheel, shift fork just can be with cam pack axially stirring along main shaft, thereby make on the strip projection top outline line on cam work surface different with the point of the compression zone contact of dynamic pressure plate, be can be different on the cam work surface with the maximum eccentricity of the point of the compression zone of dynamic pressure plate contact, the broken like this working clearance just can change because of the motion amplitude of dynamic pressure plate is different, and therefore the degree of crushing of the housing of the nut that is squeezed also changes.

The utility model is mainly used in nut broken shells such as walnuts, has to regulate the broken working clearance easily, makes the nut housing reach the advantage of the degree of crushing of anticipation.
