The elastic rod 7 supports the vibration plate 5 under the action of the first spring 10, the second spring 73 is sleeved on the elastic rod 7 in order to reduce the overall vibration noise of the feeder, and when the elastic rod 7 falls, the baffle plate 72 presses the second spring 73 to compress downwards, so that the vibration plate 5 is buffered, and the vibration plate 5 or the rocking plate 4 is prevented from striking on the upper box body 1 to generate noise.

The outer bottom surface of the lower box body 2 is provided with a guide cylinder 14 in a regular mode, and the lower end of the elastic rod 7 extends into the guide cylinder 14 and is connected with the guide cylinder 14 in a sliding mode. When the vibration plate 5 presses the elastic rod 7 to move downwards, the elastic rod 7 slides up and down in the guide cylinder 14, and the guide cylinder 14 guides the elastic rod 7.

At least two elastic rods 7 are uniformly and fixedly connected with the vibrating plate 5. The second springs 73 are continuously compressed and rebounded during working, a single spring bears overlarge load and is easy to fatigue, the service life of the spring is shortened, a plurality of spring rods 7 which are uniformly distributed are arranged, namely, a plurality of springs which are connected in parallel are arranged, the elastic force of the spring is increased while the vibration plate 5 is effectively supported, and the elastic force of the single spring follows hooke's law, namely F₁= kx, where k is the spring constant of the spring and x is the deformation of the spring, and F is present when two springs are connected in parallel₂=k₁x+k₂x, the larger the elasticity is, the more effective the shock absorption function can be played.

One side of the lower box body 2 close to the bottom end of the upper box body 1 is opened. When dregs or small-particle waste materials drop to the lower box body 2 through the elastic rod 7 holes, workers clean the dropped dregs and waste materials through the open end on the lower box body 2.

The one end of keeping away from rocking plate 4 on vibration plate 5 is rotated and is linked there is connecting plate 6, and connecting plate 6 keeps away from the fixed spheroid 61 that is equipped with of one end of vibration plate 5, go up box 1 and seted up circular slot 7 on one side of high-end, the cross sectional shape of circular slot 7 is the major arc form and the circular slot 7 upper end that the internal diameter is greater than spheroid 61 and is opened, spheroid 61 rotates and sliding connection with circular slot 7. Vibrating plate 5 can produce the clearance between the in-process of work and last box 1, for preventing that building rubbish from falling down between vibrating plate 5 and the last box 1, set up connecting plate 6 and realize the sliding connection between vibrating plate 5 and the last box 1, connecting plate 6 when the installation, slide spheroid 61 in circular slot 7 from the open department in circular slot 7 upper end, spheroid 61 slides from top to bottom in circular slot 7 when connecting plate 6 reciprocates, spheroid 61 rotates in circular slot 7 when connecting plate 6 swings.

The utility model discloses when using, fall building rubbish on vibration board 5, vibration board 5 is forced to vibrate under the common effort of first spring 10 and second spring 73, and the material then uses this vibration as power, constantly vibrates and moves down under the action of gravity and forms the slip and throw the motion to make the material move forward and reach the feed purpose.
