Description

Jigging conveyer

The utility model relates to a kind of machinery by the oscillating action convey materials, can be widely used in mass transport and screening in the industries such as food, medicine, grain, tobacco, building materials, generating, smelting ore deposit.

Jigging conveyer is generally by delivery chute, base, actuating unit and include eccentric bushing, bearing, the transmission device of driver elemenies such as connecting rod constitutes, as notification number is that the Chinese utility model patent " fine powder material jigging conveyer " of CN2057915 promptly discloses a kind of by delivery chute, drive the mechanism of shaking, the fine powder material jigging conveyer that laminated spring and base are formed, wherein drive the transmission shaft two ends setting-up eccentricity cover of the mechanism of shaking, bearing and bearing carrier ring are installed on the eccentric bushing, connecting rod is connected with bearing carrier ring and eccentric rotary is passed to delivery chute, under the directional tagging of laminated spring, delivery chute is done linear reciprocating motion, no matter how structure changes existing jigging conveyer, being used for to the transmission device of delivery chute transferring power wherein is essential, and this makes the overall cost of machine increase, and consumable accessory is more in real work, noise is bigger.

The purpose of this utility model just is to provide at above-mentioned prior art present situation a kind of jigging conveyer that does not have specially to the transmission device of delivery chute transferring power.

The purpose of this utility model is achieved in that jigging conveyer includes delivery chute, actuating unit, frame and base, between frame and delivery chute, be provided with some to laminated spring, it is characterized in that described actuating unit is arranged in the frame, comprise that motor and two pairs are placed up and down and the side-looking line of both each axis of rotation is the eccentric block of oblique line, these two pairs of eccentric blocks are rotated with speed through the transmission device driven in synchronism by motor, and the opposite and phase place of its hand of rotation roughly differs 180 °.

Simply, described two pairs of eccentric blocks can be driven by belt and same set of gear pair; For the purpose of damping, can between frame and base, be provided with cylindrical spring.

Compared with prior art, the utility model has omitted the transmission device that is exclusively used in delivery chute in traditional jigging conveyer, and produce vibration also directly by double vibrations before and after the laminated spring driving delivery chute work by actuating unit, it is simple in structure, cost is low, efficient is high, noise is low, the life-span is long, more adapts to China's national situation than external like product.

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, jigging conveyer comprises that delivery chute 1, actuating unit 2, frame 3 and base 4 constitute: delivery chute 1 is provided with sieve plate 11 and take-up device thereof, the user can change various types of sieve plates 11 as requested, can use after take-up device is fixed;

The middle part of frame 3 is for containing bucket, actuating unit 2 is arranged on the rear portion discharging opening of delivery chute (relatively and) of frame 3, comprise motor 21 and two pairs of eccentric blocks 24, the two pairs of eccentric blocks 24 are placed up and down and the side-looking line PQ and the vertical direction of both each axis of rotation have an angle α, the size of α is good with 10 °～30 °, with 20 ° is the best, these two pairs of eccentric blocks 24 are driven and rotate synchronously through belt 22 and same set of gear pair 23 by motor 21, opposite and the phase place of its hand of rotation roughly differs 180 °, referring to Fig. 2;

Be provided with many laminated springs 8 to being parallel to each other between frame 3 and delivery chute 1, laminated spring 8 is good with the side-looking line PQ that is parallel to 24 rotating shafts of above-mentioned two eccentric blocks; For making laminated spring 8 can better amplify amplitude, its cross-sectional shape with up-thin-low-thick trapezoidal be good, as shown in Figure 3, Figure 4; For corrosion prevention and make outward appearance more neat and artistic, also can be covered with plastics 9, integrated through injection molding at laminated spring 8 skins;

For the purpose of damping, between frame 3 and base 4, be provided with cylindrical spring 6, and be provided with antivibration pad 7 thereon and link with frame 4, be arranged with at it and regulate bolt of rear end plate 5 and link with base 4;

Base 4 is support sections of complete machine, and it is arranged with support screw 41 and castor 42, withstands the bottom surface by support screw 41 during use, and height can be regulated as required, then receives upper support screw mandrel 41 when mobile and castor 42 is landed get final product.

During work, motor 21 rotates, two eccentric blocks 24 rotate synchronously, because both phase places roughly differ 180 °, thereby when going to relative status, they then produce equidirectional centnifugal force, the direction of this centnifugal force is perpendicular to the side-looking line PQ of above-mentioned two pairs of each axis of rotation of eccentric block, when they go to opposing state (state shown in Fig. 2), then produce the opposite power of both direction and cancel out each other, therefore the continuous rotation of eccentric block 24 will produce the t1-t2 amplitude of reciprocal angular oscillation on the vertical surface of the side-looking line PQ of two eccentric block rotating shafts, laminated spring 8 reciprocally swingings of the oblique setting of this vibratory drive drive delivery chute 1 then and produce the porpoise of horizontal direction, thereby the material on the sieve plate 11 is constantly moved forward; The vertical shake of produced simultaneously relative base plane is then disappeared by the shock damping action because of cylindrical spring 6 and antivibration pad 7 thereof.
