Abstract

The utility model provides a mixer material cylinder swinging device, which is a mechanical device which swings the material cylinder or fixes the material cylinder on a required slope angle when the material cylinder rotates. A special centre support shaft is adopted to combine the material cylinder and a cradle firmly, and the cradle swings or rotates by 360 DEG, which does not affect the self rotation of the material cylinder. The utility model, which is manipulated through an elastic positioning handle, operates flexibly and reliably.

Description

Oscillating device of mixer drum

The utility model is a kind of mixer barrel, under rotation situation, can wave the mechanical device of rotation.It mainly is suitable for support and mixes machinery, also is suitable for other in rotation, needs the mechanical device of swinging simultaneously.

The existing mixer barrel rocking equipment of having sold on market is by a pair of gears engaged, perhaps by the transmission of worm and gear gearbox, the mixer barrel is waved, complex structure, and volume is bigger, heavy.And the mixer barrel normally adopts the pallet of welding to be connected with the barrel bolt, and for example: No. 87212381, the Chinese patent of announcing on September 1st, 1988, hand propelled mortar concrete mixer adopts this connected mode exactly.During owing under fully loaded transportation condition, work, bear, the connection place is damaged than high pulling torque and moment of flexure.

The purpose of this utility model is to overcome the shortcoming that aforementioned mixer exists, and adopt a kind of handle that waves that has the elastic force location and can be fixed on predetermined several position on demand, the barrel that is installed on the reel cage, wave like a cork, the structure dexterity, solid and reliable.

This special and do not adopt gear engagement method, make the rocking equipment of mixer barrel, be to adopt handle with elastic force location, wave and rotate supporting the barrel of clamping on reel cage also.From Fig. 1 as seen, power passes to the awl gear ring 2 that is fixed on the barrel 3 from bevel gear shaft 1, rotates thereby drive to stir barrel 3, requires barrel 3 to rotate during work, also require barrel according to circumstances to wave or constant tilt under a certain angle.This realizes that by reel cage 4 the solid minor axis 4b of reel cage 4 and hollow minor axis 4a firmly link into an integrated entity with reel cage 4, and respectively by rolling bearing 8,13,14 and bearing block 12, is supported on frame 9 and 11.And with reel cage 4 all-in-one-piece bearing block 4C, supporting central shaft 10 again, central shaft 10 is special axles, barrel 3 and reel cage 4 is coupled together, and can rotate in bearing block 4C.Some locating holes are arranged on the location-plate 5, and weld together with frame 9.Because minor axis 4b stretches into the bottom of handle 7, when operating grip 7, can make positioning head 6 leave location-plate 5, after rotating a certain angle, make 6 to insert in the hole of location-plate 5 again, mixing drum 3 is rotated under a certain angle condition that tilts, that is to say the influence that the rotation of barrel 3 is not waved by reel cage 4.

This barrel rocking equipment adopts roller bearings, and is very brisk during rocking action, when handling elastic force position fixing handle 7, as long as slight exerting oneself just can be realized the rocking action of barrel.Central support shaft is very firm, because manipulation device weight is little, thereby reduces shelf design intensity, and overall weight is lightened, and volume is little.All become easily when moving or operate, labour intensity obviously reduces.

Accompanying drawing is described an embodiment of the present utility model:

Accompanying drawing 1, mixer barrel rocking equipment schematic diagram;

Accompanying drawing 2, the center support axial section;

Accompanying drawing 3, elastic force position fixing handle profile;

The embodiment description of drawings.Accompanying drawing 1 is a mixer barrel rocking equipment, when control crank 7, make reel cage 4 swings, bearing block 4C swings thereupon, can drive central support shaft 10 swings, and the E-E section sees accompanying drawing 2 for details, when central shaft drives the barrel swing, awl gear ring 2 and bevel gear shaft 1 mesh together all the time, and therefore, barrel 3 is when waving or fix a certain angle of inclination, still can rotate, the swing of barrel 3 and rotation can be carried out simultaneously.Because reel cage minor axis 4a and 4b are in same center line, and, therefore on frame 9,11 and bearing block 12, rotate very brisk with rolling bearing 8,13,14 supports.When positioning head 6 inserted in the location-plate 5, the angle of inclination of reel cage 4 and barrel 3 was just fixing.

Accompanying drawing 2 is central support shaft sectional structure charts.Support by bearing 37,39 in the bottom of central shaft 10, and separate,, put gland 40 by nut 42, split pin 41 location through encircling 38, tighten 43 after, just be fixed up in the position of central shaft 10.Middle part and back-up block 36 at central shaft 10 are in the same place with pallet 35 assembly weldings.On the top of central shaft 10, by key 31, connect with axle sleeve 29, and axle sleeve 29, top 30, bottom blade 32 and disk 33 be assembly welding together, constitute the combination bottom blade that has keyway.Central shaft 10 passes barrel 3, and by disk 33 and pallet 35 and bolt group 34, barrel 3 tightly clamping on central shaft.Therefore, when reel cage 4 swings, barrel 3 combines very firmly with reel cage 4, and running is reliable.

Accompanying drawing 3 is elastic force position fixing handle sectional structure charts.Be welded with handle 7 in framework 16 both sides, fixing positioning head 6 by screw 15 above, spring support ring 17 also is welded on 16.Pressing plate 19, the location to spring 18 is played by screw 20 in top; The middle part is fixed on the reel cage 4b minor axis by screw 21; The bottom is fixed on the pedestal 23 by screw 22.See from the F-F section, door frame 25 therebetween set minor axis 4b, and by axle 24, pedestal 23, door frame 25 and framework 16 are linked together.But door frame 25 and pressing plate 19 are constant as end with respect to the position of reel cage minor axis 4b, and framework 16 can move with respect to door frame 25, pressing plate 19 in the direction of arrows with axle 24, does not break away from door frame 25.Therefore, when handle 7, when spurring according to arrow 26 directions, can make positioning head 6 leave location-plate, spring 18 is compressed.But this moment, and then handle 7 presses arrow 27 or 28 directions when rotating, and just can drive door frame 25, minor axis 4b presses arrow 27 or 28 directions are rotated, and just makes the reel cage action, thereby realizes the action of waving, and also can make reel cage rotate 360 °.But when operator's release handle 7,,, reel cage is fixed so positioning head 6 inserts in the fixed head because the effect of spring 18 sets back framework 16.Action easy and flexible during operation, accurate positioning.
