[0017] As Figure 1 and Figure 2The utility model discloses a single row feeding mechanism, including vibrating screen 1, feeding chute 2 and limiting mechanism 3, the feeding chute 2 one end is connected with vibrating screen 1, and the limiting mechanism 3 is located on feeding chute 2, the limiting mechanism 3 includes connecting seat 31, sliding rod 32, reset torsional spring 33, connecting arm 34 and limiting rod 35, connecting seat 31 is located on feeding chute 2, sliding rod 32 is fixed on connecting seat 31, the connecting arm 34 one end is connected with limiting rod 35, and the other end is equipped with connecting hole 341, the connecting arm 34 is set on sliding rod 32 through connecting hole 341, and can rotate relative to sliding rod 32, reset torsional spring 33 is located on sliding rod 32, and is connected limiting rod 35 and connecting seat 31, under normal working condition, limiting rod 35 is located directly above feeding chute 2.
[0018] Adopt the above structure, the limiting rod 35 is equipped on feeding chute 2, the limiting rod 35 is swingably equipped on sliding rod 32 through connecting arm 34, and the top of material in feeding chute 2 is pressed by limiting rod 35, can guarantee that all materials are arranged in feeding chute 2 in good order. On the one hand, reset torsional spring 33 provides constant compression force for limiting rod 35, and when conveying different size materials, limiting rod 35 can automatically adjust to the position of different distance with feeding chute 2, has self -adaptation ability, on the other hand, when the material in feeding chute 2 is stuck, operating personnel can conveniently open limiting rod 35, and the material stuck in feeding chute 2 is taken out, when operating personnel release limiting rod 35, limiting rod 35 will press the material on feeding chute 2 again under the drive of reset torsional spring 33, and daily maintenance is convenient.
[0019] In order to expand the sliding range of the limiting rod 35, the connecting seat 31 is upwardly extended from the side of the feeding chute 2, and the two ends of the sliding rod 32 pass through the connecting seat 31. Preferably, in an embodiment, the sliding rod 32 is fixed by two connecting seats 31, and the sliding rod 32 is provided with a connecting arm 34 at the position outside the two connecting seats 31. Since the two connecting arms 34 are fixedly connected with the limiting rod 35, the distance between the two connecting arms 34 is greater than the distance between the two connecting seats 31, and the outside of the two connecting seats 31 is provided, so that the connecting arm 34 cannot be separated from the sliding rod 32, but can slide on the sliding rod 32 with a predetermined stroke. Through the above arrangement, the feeding chute 2 is provided with a horizontal conveying section 21 at the end, and the discharge end of the limiting rod 35 is provided with a horizontal limiting section 351 corresponding to the horizontal conveying section 21, so that the conveying disc 4 can be directly arranged in front of the horizontal conveying section 21, and the side of the conveying disc 4 is provided with a conveying tooth 41.
