Specific embodiments

[0023] Refer to the attached Figures 1-4 In the present invention, a pipe chain type discharging device is provided, which includes a pipe chain type conveyor and a plurality of hoppers 2 arranged along the length direction of the conveying pipe 1 in the pipe chain type conveyor. The key lies in that: a vibrating discharging assembly is provided between the hopper 2 and the conveying pipe 1. The vibrating discharging assembly includes an installation cylinder 3 fixed on the feeding pipe 1-1 and located above the hopper 2, a rubber plate 4 fixed on the top of the installation cylinder 3, a vibrator 5 fixed on the outer side and the inner side of the rubber plate 4 respectively, and a vibrating plate 7 for vibrating the tray 6 in the feeding pipe 1-1. The vibration force generated by the vibrator 5 is transmitted to the vibrating plate 7 to vibrate the tray 6, thereby improving the discharging effect. The rubber plate 4 plays a role in providing the amplitude of the vibrating plate 7 and sealing, and parts such as springs can be no longer used. In this embodiment, the material of the rubber plate 4 is wire-inserted nitrile rubber.

[0024] Refer to the attached Figures 2-4 On the top of the installation cylinder 3, there is a pressing plate 10 and a supporting fixing bolt for fixing the rubber plate 4 on the installation cylinder 3. The vibrator 5 is arranged at the central position of the rubber plate 4 so that the vibrator 5 has the best vibration effect.

[0025] A T-shaped connecting plate 8 is fixed on the vibrating plate 7. The vibrating plate 7 is connected to the vibrator 5 by a connecting bolt 9 passing through the connecting end of the connecting plate 8 and the rubber plate 4. A sealing ring can also be provided between the connecting bolt 9 and the rubber plate 4 and between the rubber plate 4 and the vibrator 5 to ensure the sealing effect.

[0026] Both ends of the vibrating plate 7 are tilted upward to facilitate the movement of the tray 6.

[0027] A tipping valve assembly for closing the blanking opening in the closed conveying pipe 1-1 is provided on the hopper 2 to achieve the unloading control of the hopper 2. The tipping valve assembly includes an arc-shaped valve plate 11 located inside the hopper 2, a connecting shaft 12 rotatably limited on the hopper 2 with both ends located on the inner and outer sides of the hopper 2 respectively, a rotating arm 13 connecting the arc-shaped valve plate 11 and the connecting shaft 12, and a driving assembly located outside the hopper 2 and driving the connecting shaft 12 to rotate. The driving assembly includes a driving arm 15 located outside the hopper 2 and connected to the connecting shaft 12, and a driving cylinder 16 with both ends hinged to the driving arm 15 and the hopper 2 respectively.

[0028] The arc-shaped valve plate 11 is hinged on the rotating arm 13. Limiting bosses 14 for limiting the rotation angle of the arc-shaped valve plate 11 are respectively provided on both sides of the rotating arm 13 at the hinge position to prevent the freedom of the arc-shaped valve plate 11 from being too large to close the blanking opening on the conveying pipe 1.

[0029] See attached Figure 1 As shown, the tube chain conveyor includes a head box 17, a tail box 18, a conveying pipe 1, a driving sprocket located inside the head box 17 and a supporting driving motor 19, a driven sprocket located inside the tail box 18, a chain located between the driving sprocket and the driven sprocket, and a tray 6 arranged on the chain. A feeding box 22 is provided on the conveying pipe 1 on one side of the tail box 18.

[0030] The conveying pipe 1 includes a return pipe 1-2 and a feeding pipe 1-1 located below the return pipe 1-2. A connecting bracket 20 is provided between the return pipe 1-2 and the feeding pipe 1-1, and a supporting bracket 21 is provided between the connecting bracket 20 and the ground to ensure the stable connection of the conveying pipe 1.

[0031] The working process of the device of the present utility model is as follows: 1. The driving motor 19 is started, and the chain and the tray 6 on the chain are driven to make a rotary motion through the gear. 2. When it is necessary to unload to a certain hopper 2, the arc-shaped valve plate 11 is driven to act by the driving cylinder 16 to open the unloading opening on the conveying pipe 1, and the vibrator 5 is started while opening the valve plate. 3. Materials are added into the feeding box 22, and the materials fall into the hopper 2 when passing through the unloading opening driven by the tray. The vibrator 5 transmits the vibration to the chain and the tray 6 inside the pipeline through the connecting plate 8, so that the chain and the tray 6 generate vibrations with a certain frequency and amplitude during unloading, prompting the materials to fall off from the chain and the tray 6 and quickly discharging them into the hopper 2 through the unloading opening.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
