DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of the present application.

[0033] The present embodiment sets the adjusting tooth plate and gear on the side of the rack where the driven shaft is arranged, and uses the adjusting tooth plate and gear to adjust the distance between the driven shaft and the rack to realize the tension adjustment of the ring chain plate, and the adjusting tooth plate and gear can move in two directions. By rotating the tension hand wheel to drive the adjusting member to adjust the distance between the driven rod and the rack, the tension adjustment function of the two chains is realized, and the normal transportation work is not affected by the large or small tension. The specific implementation is as follows:

[0034] As shown in Figures 1-4 A chain plate conveyor, comprising a rack 1 and a transmission shaft and a ring chain plate 2, the transmission shaft comprising a driving shaft 3 and a driven shaft 4, the driving shaft 3 and the driven shaft 4 being rotatably arranged at both ends of the rack 1 through a bearing seat, the rack 1 being symmetrically provided with a connecting support 5 near one end of the driving shaft 3, the connecting support 5 being integrally connected with the outer side of the rack 1, the inner sides of the two connecting supports 5 being fixedly connected with an adjusting plate 6, a sliding groove being formed in the adjusting plate 6, and an adjusting member being slidably embedded in the sliding groove, and the bottom of the rack 1 being fixedly connected with a base 7 for lifting the rack 1.

[0035] Here, the tension adjusting mechanism is arranged on the side of the rack 1 where the driven shaft 4 is arranged to adjust the tension of the chain plate. The adjusting member on the adjusting plate 6 enables the driven shaft 4 to be adjusted in both directions to adjust the tension of the two chains. This avoids the tension being too large, which can cause the chain to break, and too small, which can affect normal transportation. The base 7 is arranged to assist in supporting and lifting the rack 1, which improves the service life of the chain plate machine and enables it to be used in different height scenarios.

[0036] Here, in order to improve the stability of the rack 1 and provide sufficient support for the connecting plate 16, a plurality of support rods are arranged between the annular chain plates 2 on the rack 1. In addition, the connecting bracket 5 is a bracket composed of a plurality of vertical rods arranged on the extension rods of the rack frame and perpendicular to the extension rods.

[0037] As a preferred embodiment, the adjusting member includes an adjusting tooth plate 8, a sliding block 9 integrally arranged on the side surface of the adjusting tooth plate 8 and slidingly connected with the sliding groove, and an adjusting gear 10 arranged on the upper end of the adjusting tooth plate 8 and fixedly connected with the driven shaft 4.

[0038] Here, the sliding block 9 on the adjusting tooth plate 8 slides relative to the adjusting plate 6, and the adjusting gear 10 is arranged on one side of the adjusting tooth plate 8 to adjust the position of the adjusting tooth plate 8 relative to the adjusting plate 6.

[0039] As a preferred embodiment, the adjusting member includes an adjusting tooth plate 8, a sliding block 9 integrally arranged on the side surface of the adjusting tooth plate 8 and slidingly connected with the sliding groove, and an adjusting gear 10 arranged on the upper end of the adjusting tooth plate 8 and fixedly connected with the driven shaft 4.

[0040] Here, the adjusting plate 6 is arranged inside the connecting bracket 5 and connected with the driven rod, and the adjusting gear 10 is arranged above the adjusting plate 6 and matched with the adjusting rod. The tensioning hand wheel 13 is connected with the tensioning hand wheel 13 through the connecting rod 12. When the tensioning hand wheel 13 is rotated, the adjusting tooth plate 8 is displaced, thereby adjusting the distance between the driven rod and the rack 1 to adjust the tension of the annular chain plate 2. This can effectively and accurately control the tension and improve the reliability and stability of the tension adjustment of related equipment.

[0041] Here, in order to prevent the adjusting tooth plate 8 and the adjusting plate 6 from sliding back to the original position after adjustment, the distance between the driven sprocket 15 and the rack 1 is changed, which causes the tension of the conveying chain 17 to change. Therefore, a limiting hole is arranged on the support bracket 11, and the limiting rod is fixed relative to the tensioning hand wheel 13.

[0042] As a preferred embodiment, a motor is fixedly arranged on the outer side wall of the frame 1 near either end of the driving shaft 3, and the output shaft of the motor is fixedly connected with the driving shaft 3. A driving sprocket 14 for the circumferential rotation of the chain plate is arranged on the inner side wall of the frame 1 near either end of the driving shaft 3. A driven sprocket 15 is arranged on the inner side wall of the adjusting toothed plate 8 near either end of the driven shaft 4.

[0043] Here, a mounting rack is arranged on the frame 1 near the driving shaft 3, and the motor is fixedly arranged on the mounting rack to provide power for the rotation of the driving shaft 3.

[0044] As a preferred embodiment, the chain plate comprises a plurality of connecting plates 16 connected in sequence and a conveying chain 17 fixedly connected to the two ends of the connecting plate 16. The teeth of the driving sprocket 14 and the driven sprocket 15 are matched with the conveying chain 17.

[0045] As a preferred embodiment, the base 7 and the upper end face of the frame 1 are provided with a lifting member, which comprises an electric telescopic rod 18 fixedly arranged on the upper end of the base 7. The free end of the electric telescopic rod 18 is fixedly connected with the bottom edge of the frame 1 through a fixed rod 19.

[0046] Here, the electric telescopic rod 18 is arranged between the frame 1 and the base 7. The frame 1 is lifted as a whole by the extension and retraction of the telescopic rod, so as to adjust the height between the frame 1 and the base 7. In this way, the height of the conveying frame can be adjusted to adapt to different conveying conditions.

[0047] As a preferred embodiment, the bottom of the frame 1 is provided with a plurality of chain idlers 20 corresponding to the conveying chain 17 for lifting the conveying chain 17.

[0048] Here, the adjusting member can keep the conveying chain 17 in a tensioned state. However, the tension adjustment of the conveying chain 17 by the tensioning wheel has a certain limit. When the limit is exceeded, the conveying chain 17 cannot work. In order to ensure that the tension adjustment of the conveying chain 17 is moderate, the chain idlers 20 are arranged below the conveying chain 17 for lifting the conveying chain 17. In this way, the tension adjustment of the conveying chain 17 by the tension adjustment mechanism has a margin, and the conveying chain 17 remains in a normal state, which is conducive to the smooth operation of the conveying groove.

[0049] As a preferred embodiment, the base 7 is provided with a moving wheel 21 at the two ends of the long edge, and a brake member is arranged in cooperation with the moving wheel 21.

[0050] As a preferred embodiment, the frame 1 comprises a frame plate and a frame frame integrally connected with the frame plate. The electric telescopic rod 18 is fixedly connected with the bottom edge of the frame frame, and the connecting support 5 is fixedly connected with the end of the frame frame.

[0051] As a preferred embodiment, the middle part of the connecting support 5 is provided with several reinforcing ribs.

[0052] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
