The specific embodiment

Shown in Fig. 1,2, the circle vibrations screening machine that the utility model is designed, it has a pedestal 10, and shakes group 20 and one screening group 30, wherein the top of this pedestal 10 is provided with screening group 30, between screening group 30 and pedestal, be provided with and shake group 20, make the screening group 30 that is positioned at pedestal 10 tops produce vibrations by shaking group 20 jarring forces that produced, to reach the screening operation of workpiece or material.

Cooperation is referring to shown in Figure 3, this pedestal 10, it is the frame of a hollow, concrete external form shown in the figure is a circular support body, periphery above it is interval with several elastic components that is circumferential arrangement 11, and this elastic component 11 can be the helical spring of standard, is provided with a disk body 12 at the other end place of each elastic component 11, this disk body 12 is that a plate body and central authorities are formed with opening 13, and its top mutually combines with this screening group 30;

This shakes group 20, it is provided with a motor 21, rotating shaft two ends at this motor 21 are respectively equipped with an eccentric disk 22, be that eccentric disk 22 1 ends and rotating shaft are fixed, the other end is provided with counterweight 23, the weight of this counterweight 23 can cooperate designed amplitude size to be adjusted, when rotating shaft is activated, this rotating shaft can drive eccentric disk 22 rotations at two ends simultaneously, be provided with holder 24 in the body outside of motor 21 again, this motor 21 can be arranged on opening set on the disk body 12 13 places, and its holder 24 1 sides are positioned at the side, disk body 12 top of opening 13 peripheries, its another embodiment can be located at the holder 24 of motor 21 side, disk body 12 below, is the fixedly side of elastic component 11 and disk body 12, and utilizes holder 24 to mutually combine motor 21 and disk body 12 fixing;

This screening group 30 is a hollow frame group, portion is provided with filter screen group 36 and another and then is provided with a taper base plate 35 at interval within it, make and be formed with an accommodation space in the framework of base plate 35 belows, the top of hollow frame is provided with dog-house 31 again, on the framework above the filter screen 36, be provided with the sludge discharge tube 33 that communicates in addition, reach and on the framework above the base plate 35, be provided with discharging opening 32, screening is organized 30 belows and is set on the disk body 12 again, utilize anchor clamps 34 that both are assembled mutually at its place of coinciding, be arranged at motor 21 rotating shafts one end this moment, in the accommodation space, these anchor clamps 34 are disposed relatively by the circular cramp of two halves to be formed below screening group 30 for the eccentric disk 22 of upper end and 23 of counterweights.

When vibrations screening machine of the present utility model in use, with motor 21 drive arrangements eccentric disks 22 and counterweight 23 thereof, and the hollow frame that makes screening group 30 produces the designed amplitude of shaking, if article or material are dropped into by dog-house 31, just the article after residue and the processing can be sent by sludge discharge tube 33 discharges or discharging opening 32 respectively via the filtration of screening group 30;

Moreover since the utility model be with the holder 24 of its motor 21 outsides directly and disk body 12 mutually combine fixing, make the outer intermarginal distance of the hollow frame that shakes group 20 vibroseises that produced and screening group 30 shorten, so when 21 horsepowers big or small in the set motor of group 20 is shaken in design, if when the screening group of configuration and prior art same size shown in Figure 4 and framework thereof, the horsepower of motor that the utility model uses 50 can be less and still can obtain designed amplitude of vibration, because the horsepower of the employed motor 21 of the utility model is less, will comparatively save than the required energy that expends of the jarring machine of prior art;

Again owing to motor 21 than fraction horsepower, make the weight saving of whole jarring machine, to be easy to transportation and mobile, its process is comparatively laborsaving, moreover in screening process, come from the level of noise that motor 21 running produced and also can significantly reduce, owing to the motor 21 that shakes group is arranged on the disk body 12, can be convenient to the maintenance of its mechanism or the configuration adjustment of counterweight and weight in addition.
