BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 is a schematic structural view of an embodiment of the present application;

[0015] Figure 2 is a top view of an embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will clearly and completely describe the present utility model in conjunction with the drawings and embodiments:

[0017] As Figures 1 to 2 shown, an eight-shaft vibrator for conveying according to the present utility model includes two parts of structures arranged symmetrically on the left and right. Each part of the structure includes two low-speed shafts 2 and two high-speed shafts 3 rotatably disposed on a housing 1. Each high-speed shaft 3 and low-speed shaft 2 are rotatably connected to the housing 1 through bearings 4 to ensure the stability of the rotation of the low-speed shaft 2 and the high-speed shaft 3; two high-speed eccentric blocks 5 are installed on two of the high-speed shafts 3, and two low-speed eccentric blocks 6 are installed on two of the low-speed shafts 2; the low-speed shaft 2 is driven by a driving member. Two high-speed shafts 3 in each part of the structure are connected by a coupling 7, and a connecting member is provided on the high-speed shafts 3 of the two parts of the structure to ensure the stability and synchronism of the operation of the entire vibrator, thereby realizing the stable and orderly conveying of materials; at the ends of the low-speed shaft 2 and the high-speed shaft 3 in each part of the structure away from the driving member, they are connected in pairs through transmission members, that is, one high-speed shaft 3 and one low-speed shaft 2 in each part of the structure are connected through transmission members to realize the transmission between the high-speed shaft 3 and the low-speed shaft 2.

[0018] During operation, the driving member drives the low-speed shaft 2 to rotate. The low-speed shaft 2 and the high-speed shaft 3 are driven by a transmission member. The high-speed eccentric blocks 5 and the low-speed eccentric blocks 6 on the two parts are symmetrically rotated in opposite directions. The vibration forces of the high-speed eccentric blocks 5 and the low-speed eccentric blocks 6 are superimposed in the front-back direction of the vibrator and cancelled in the left-right direction, so as to generate a stable front-back vibration force for the vibrator, facilitating the continuous feeding and conveying of scrap steel.

[0019] Further, on each part of the structure, two high-speed shafts 3 are arranged in the middle of the housing 1, and two low-speed shafts 2 are arranged at both ends of the housing 1. And the two high-speed shafts 3 and the two low-speed shafts 2 on each part of the structure are vertically arranged, and the two high-speed shafts 3 and the two low-speed shafts 2 are arranged in a straight line to enhance the vibration force and ensure stability.

[0020] Further, the driving member includes a motor 8. A driving pulley 9 is arranged on the rotating shaft of the motor 8, and a driven pulley 10 is arranged on the low-speed shaft 2. A transmission belt 11 is sleeved on the driving pulley 9 and the driven pulley 10. During operation, the motor 8 drives the transmission belt 11 to rotate the low-speed shaft 2, and the low-speed shaft 2 drives the high-speed shaft 3 to rotate through a transmission member. The transmission member includes a large gear 12 arranged on the low-speed shaft 2 and a small gear 13 arranged on the high-speed shaft 3. The large gear 12 and the small gear 13 on each part of the structure are meshed and driven. In addition, the number of teeth of the large gear 12 is twice that of the small gear 13 to ensure that the high-speed shaft 3 rotates at twice the speed of the low-speed shaft 2 under the meshing of the small gear 13 with the large gear 12. In addition, in this embodiment, the connecting member is a synchronous shaft 14 to ensure the synchronism of the operation of the two parts of the structure. In this embodiment, only the large gear 12 and the small gear 13 are meshed and driven, and the large gears 12 at the ends do not contact each other, which can extend the service life of the large gear 12, reduce the generation of noise, and at the same time reduce the manufacturing difficulty.

[0021] In the present utility model, during operation, the motor 8 drives the low-speed shaft 2 to rotate through the transmission belt 11, so that the high-speed eccentric blocks 5 and the low-speed eccentric blocks 6 in the left and right parts of the eight-shaft vibrator of the present utility model rotate symmetrically in opposite directions. The vibration forces generated by the high-speed eccentric blocks 5 and the low-speed eccentric blocks 6 are superimposed in the front-back direction of the vibrator and cancelled in the left-right direction, and further a stable front-back vibration force is generated for the vibrator to realize the continuous feeding and conveying of scrap steel. The vibration force is large and the stability is strong, effectively ensuring the working efficiency.

[0022] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
