Embodiment 1

[0027] The frame 1 is provided with a sieve plate 6 and a combined screening device; the combined screening device is provided with two layers of sieving plates, and is located below the sieve plate 6; the vibrating bar 11 is also installed in the sieving plate, and the vibrating bar 11 It can move axially; and the vibrating bar 11 includes a solid segment 1102 and a hollow segment 1103 , and the solid segments 1102 and hollow segments 1103 of two adjacent vibrating bars 11 are alternately arranged. The frequency conversion motor inside the driving device 3 outside the frame 1 works, and the kinetic energy is transmitted to the vibrator 2 through the pulley mechanism, and the vibrator 2 is driven by a biaxial eccentric to make the device generate vibration force, driving the entire frame 1 to vibrate; Put it into the inclined blanking plate 5, the stone will slide down on the upper end of the sieve plate 6 along the blanking plate 5, and the impurities will fall on the sieve pl...

Abstract

The invention discloses a vibrating feeder. The vibrating feeder comprises a rack and vibrating strips; a sieve plate and a combined screening device are arranged in the rack; the combined screening device is at least provided with a layer of sieve plate and is arranged below the sieve plate; the vibrating strips are movably arranged in the sieve plate; and each vibrating strip comprises a solid section and a hollow section, and the solid sections of every two adjacent vibrating strips and the hollow sections of every two adjacent vibrating strips are arranged in a staggered manner. The vibrating feeder has the beneficial effects that the reset spring piece can provide elastic potential energy for the vibrating strips, axial dislocation movement is generated by means of different gravity centers of the adjacent vibrating strips, so that the stone impurities can generate a relative action among the vibrating strips, so that impurities can quickly pass through the sieve plate. Accordingto the specific shapes of the first sieve plate and the second sieve plate, the time that the stone can stay among the vibrating strips can be increased, and the vibrating strips moving in the axial direction can be matched, so that the screening efficiency of the stones can be greatly improved.

Description

technical field [0001] The invention relates to a vibrating feeder and belongs to the field of mining machinery. Background technique [0002] Vibrating feeder is also called bar feeder. In the sand and gravel production line, it can continuously and evenly feed the crushing machinery, and coarsely screen the materials. It is widely used in the combined crushing and screening equipment in metallurgy, coal mines, mineral processing, building materials, chemicals, abrasives and other industries. [0003] Compared with the publication number CN207671346U, the name is called "a kind of vibrating feeder with screening module" specific structure, including spring support, vibrating frame, vibrator, motor vibrating frame and motor, the discharge of the vibrating feeder A sieving module is provided at the end, and the sieving module includes a large particle sieving layer, a medium particle sieving layer and a fine particle sieving layer, and the large particle sieving layer, the m...
