The working principle of the invention is as follows:

the invention drives the middle belt wheel shaft to rotate through the belt driving belt by the motor so as to drive the rotating disc to rotate. In the rotating process of the turntable, the upper rocking block on the turntable rotates clockwise or anticlockwise by taking the center of the turntable as a center, the upper rocking block is embedded in the strip-shaped guide groove of the oscillating bar, and then the oscillating bar is driven to swing along with the upper rocking block to do corresponding actions, so that the swinging action of the sieve sheet is realized.

Meanwhile, the middle belt wheel shaft drives the two cam shafts to rotate through belt transmission, and then drives the four cams to rotate, the rotation process of the cams realizes the action of upwards and instantly falling along the vertical rod on the bottom plate, and the action of upwards and instantly falling can be simultaneously realized by the sieve sheet supported and installed on the bottom plate through the height-adjustable support rod.

The inclination angle of the sieve sheet in the structure of the invention is adjusted by rotating the double-head left-right rotating adjusting screw rod to increase and shorten the total height of the lower loop bar of the adjusting rod and the loop bar in the adjusting rod, so that the sieve sheet has a proper inclination angle. The spring is sleeved on the upper part of the sleeve rod in the adjusting rod, and the upper end of the spring props against the sleeve rod on the adjusting rod. After the sieve sheet impacts the spring when falling down instantly in the vertical direction, the sieve sheet continuously jolts and moves in the vertical direction, so that the oscillation frequency is increased, and the material grading effect is enhanced.

The invention has the advantages that:

the machine of the invention has simple and compact structure, convenient disassembly and maintenance, power saving and low cost, and saves matched devices such as a fan and the like. Meanwhile, the sudden drop motion in the vertical direction and the unequal-speed swing in the horizontal direction are realized, and the vibration stone removing effect is good.

Detailed Description

See the drawings.

The utility model provides an oscillation destoner, pass through key 2 and be connected with motor pulley 1 including the motor, drive middle belt pulley 4 through belt 3, middle belt pulley 4 has 6 belt slots, 2 belt slots are used for with motor pulley 1 transmission, middle belt pulley 4 is connected with 5 key-types on the middle belt pulley shaft, middle belt pulley shaft 5 passes through the bearing dress and in frame 10, belt drive pulley 6 on 2 belt slots of middle belt pulley 4, belt pulley 6 has 2 respectively to adorn 1 respectively on first cam drive shaft 7 and second cam drive shaft 8 altogether. On the first cam drive shaft 7 and the second cam drive shaft 8, 2 cams 9 are mounted each. The first cam transmission shaft 7 and the second cam transmission shaft 8 are arranged on a rack 10 through bearings and fixedly rotate relative to the rack, the cam 9 pushes a bottom plate 11 upwards, the bottom plate 11 is sleeved on a vertical rod 12 in an empty mode, the vertical rod 12 is fixedly connected to the rack 10, the bottom plate 11 moves up and down along the vertical rod 12, and a lower sleeve rod 13 of an adjusting rod is in pin connection with the bottom plate 11. The lower end of a double-head left-right rotating adjusting screw rod 14 is in threaded connection with an adjusting rod lower loop bar 13, the upper end of the double-head left-right rotating adjusting screw rod 14 is in threaded connection with an adjusting rod middle loop bar 15, a spring 16 is sleeved on the upper portion of the adjusting rod middle loop bar 15, the upper end of the spring 16 abuts against an adjusting rod upper loop bar 17, the adjusting rod upper loop bar 17 is in pin connection with a sieve sheet 18, a rocker 20 is in pin connection with a rack 10, the lower rocker 20 swings relative to the rack 10 around the pin connection, the lower rocker 20 is embedded in a groove in the lower portion of a rocker 21 and can slide in the groove, and the upper end of the rocker 21 is in.
