Fig. 1 shows a motion model of a rocker arm vibrating conveyor, the motion of which is achieved by a crank and rocker mechanism. As shown in fig. 1, when the swing arm type vibration conveyor operates, the link 11 moves circularly around the epicyclic pair O, then the swing link 13 swings around the oscillating pair B0 under the pushing and pulling of the connecting rod 12, and the trough body 1 mounted on the swing link 13 swings around the swing link 13 in the track P → P1 → P2 → P1 … …. The swing motion track of the tank body 1 is an arc with the swing rod 13 as the radius. At present, the length of the swing rod 13 of the common rocker arm type vibrating conveyor is 260mm, and the connecting frame 11 has various length specifications such as 8mm, 10mm, 12mm, 15mm and the like. Taking a crank rocker mechanism with the length of the rocker 13 being 260mm and the length of the connecting frame 11 being 15mm as an example, as shown in fig. 2, the swing angle of a point P on the tank body 1 is 13 °, the swing amplitude is 60.35mm, the displacement in the diameter direction is 2.03mm, and the displacement in the diameter direction is much smaller than the swing amplitude. Therefore, in the prevention of the problem of material leakage, the arbitrary point P can be approximated to a linear motion.

Based on the above findings, as shown in fig. 3 to 7, some embodiments of the present disclosure provide a swing arm type vibrating conveyor including: a machine base (not shown), a tank body 1, a sealing bracket 2 and a sealing plate 3; wherein, the tank body 1 can be arranged on the base in a reciprocating swing way; a sealing groove 21 is formed in the sealing bracket 2; one end of the sealing plate 3 is relatively movably arranged in the sealing groove 21, the other end is fixedly connected with one of the trough body 1 and the machine base, and the sealing bracket 2 is fixedly arranged relative to the other of the trough body 1 and the machine base.

In the illustrative embodiment, by arranging the sealing plate 3 and the sealing bracket 2 with the sealing groove 21, one end of the sealing plate 3 is relatively movably arranged in the sealing groove 21 by utilizing the motion track of the trough body 1 of the rocker arm type vibrating conveyor, so that seamless sealing connection between the trough body 1 and other parts which are fixed relative to a machine base is realized, the sealing effect and the sealing reliability are improved, the generation of material leakage is effectively avoided, and the service life is prolonged. In some embodiments, the other end of the sealing plate 3 is fixedly connected with the tank body 1, and the sealing bracket 2 is fixedly arranged relative to the machine base; in other embodiments, the other end of the sealing plate 3 is fixedly arranged relative to the machine base, and the sealing bracket 2 is fixedly connected with the tank body 1.

In order to avoid the relative friction between the sealing plate 3 and the sealing bracket 2, in some embodiments, as shown in fig. 3, the thickness of the sealing groove 21 is greater than that of the sealing plate 3, so as to improve the sealing stability. In some embodiments, the difference between the thickness of the sealing groove 21 and the thickness of the sealing plate 3 is greater than or equal to 2.03mm, so that the sealing reliability and stability are ensured.

To ensure the motion stability and the sealing reliability, in some embodiments, as shown in fig. 3, the sealing groove 21 is a linear groove, and the sealing plate 3 is a straight plate.

In order to ensure that one end of the sealing plate 3 is kept in the sealing groove 21 during the reciprocating swing of the tank body 1, in some embodiments, as shown in fig. 3, the depth direction of the sealing groove 21 is consistent with the reciprocating swing direction of the tank body 1. Similarly, in some embodiments, the seal plate 3 is reciprocally swung in the groove depth direction along the seal groove 21.

Specifically, when the rocker arm type vibrating conveyor is sealed, for example, a roller discharging vibrating conveyor, as shown in fig. 4 and 5, in some embodiments, the rocker arm type vibrating conveyor further includes a blanking hopper 4 fixedly disposed on the base, the chute body 1 includes a discharging chute body 1-1, the blanking hopper 4 is located on the discharging chute body 1-1, the other end of the sealing plate 3 is fixedly connected with the discharging chute body 1-1, and the sealing bracket 2 is fixedly connected with the bottom of the blanking hopper 4. When the automatic discharging device works, the discharging groove body 1-1 swings in a reciprocating mode, and the sealing plate 3 is embedded in the sealing groove 21 of the sealing support 2 all the time, so that the phenomenon of material leakage is avoided. In some embodiments, as shown in fig. 4 and 5, the two sealing brackets 2 are respectively arranged on two sides of the bottom of the blanking hopper 4, so that the front and the back can not leak materials.

Similarly, when sealing is performed below the rocker arm type vibrating conveyor, such as a roller feeding vibrating conveyor, as shown in fig. 6 and 7, in some embodiments, the rocker arm type vibrating conveyor further comprises a front chamber fixing plate 5 fixedly arranged on the machine base, the tank body 1 comprises a feeding tank body 1-2, the other end of the sealing plate 3 is fixedly connected with the front chamber fixing plate 5 through a pressing strip 6, and the sealing support 2 is fixedly connected with the bottom of the feeding tank body 1-2. When the feeding trough body 1-2 reciprocates during working, the sealing plate 3 is always embedded in the sealing groove 21 of the sealing support 2, and material leakage at the bottom is avoided.

Some details that are well known in the art have not been described in order to avoid obscuring the concepts of the present disclosure. It will be fully apparent to those skilled in the art from the foregoing description how to practice the presently disclosed embodiments.
