DETAILED DESCRIPTION

[0027] As Figures 1 to 5 shown, a kind of ring pipe chain conveyor, including by four pipelines 1 and four steering boxes 2 being arranged in the first and last connection of four pipelines 1, the pipeline 1 and the steering box 2 first and last connection form annular structure, one of the steering box 2 is equipped with driving part 3, the pipeline 1 and the steering box 2 are equipped with annular chain 4 being connected in the first and last, the driving part 3 drives steering box and drives annular chain 4 movement in pipeline 1 and transports material, the pipeline 1 of the lower end of annular structure is equipped with feed inlet 5, the pipeline 1 of the upper end of annular structure is equipped with discharge mechanism 6;

[0028] The discharge mechanism 6 includes discharge nozzle 601, the discharge nozzle 601 is arranged in one side of pipeline 1, and pulse valve 602 is arranged on pipeline 1 in the opposite direction of the discharge nozzle 601, the pulse valve 602 is spouted compressed gas to the clearance in discharge nozzle 601, the lower end of discharge nozzle 601 is hinged with cover plate 603, the outer side of the cover plate 603 is equipped with executor 604, and the executor 604 drives cover plate 603 rotation and opens and closes discharge nozzle 601;

[0029] In the embodiment, as Figure 1 、 Figure 2 、 Figure 3As shown, the driving member 3 is a motor, which drives the sprocket in the rotating box 2 to rotate, and in turn drives the continuous movement of the endless chain 4 in the four pipes 1. The endless chain 4 is composed of a plurality of chain links 401 connected end to end, and adjacent chain links 401 are fixed with chain plates 402. Two adjacent chain plates 402 and the pipe 1 form a warehouse body for conveying raw materials. The raw materials are lifted from the feeding port 5 to the discharging mechanism 6. The actuator 604 is a pneumatic cylinder, which drives the cover plate 603 to rotate to open the discharge nozzle 601. The raw materials can fall through the discharge nozzle 601. By controlling the pulse valve 602 to spray compressed gas into the gap of the discharge nozzle, the sticky materials adhering to the endless chain 4 are blown into the discharge nozzle 601, improving the transportation efficiency. After the raw material conveying is completed, the discharge nozzle 601 is closed by the pneumatic cylinder, and the pulse valve 602 is controlled to spray compressed gas into the gap of the discharge nozzle 601, so that the sticky materials adhering to the endless chain 4 are blown into the discharge nozzle 601. After a certain period of work, the discharge nozzle 601 is opened, thereby self-cleaning the endless chain 4.

[0030] In this embodiment, as shown in Figure 4 In order to tension the endless chain 4, two sets of tensioning mechanisms 7 are designed. The tensioning mechanism 7 includes an upper guide pipe 701 with a flange at the top. The lower end of the upper guide pipe 701 extends into a lower guide pipe 702 with a flange at the bottom. The upper guide pipe 701 is connected to the pipe 1, and the lower guide pipe 702 is connected to the steering box 2. The upper guide pipe 701 and the lower guide pipe 702 are connected through an adjusting assembly 703. The adjusting assembly 703 adjusts the length of the upper guide pipe 701 extending into the lower guide pipe 702 to adjust the height of the ring structure.

[0031] The number of adjusting assemblies 703 is not less than 2. The adjusting assembly 703 includes a screw rod 703 penetrating the flanges of the upper guide pipe 701 and the lower guide pipe 702. Four nuts 704 are arranged symmetrically along the flanges on the screw rod 703. The relative position of the nuts 704 on the screw rod 703 is adjusted to adjust the length of the upper guide pipe 701 extending into the lower guide pipe 702. By adjusting the length of the stainless steel upper guide pipe 701 inserted into the lower guide pipe 702, the elongation of the endless chain 4 is compensated. Compared with the traditional method of compensating the elongation of the endless chain 4 by deforming the corrugated pipe or rubber pipe, the method has a longer service life and higher rigidity. Since the stainless steel upper guide pipe does not deform, the chain plate has good passing performance and is not prone to jamming and other situations, and the maintenance cost is low.

[0032] It is worth noting that, in this embodiment, as shown in Figure 4 In order to seal the contact surface between the upper guide pipe 701 and the lower guide pipe 702, a sealing ring can be provided between the upper guide pipe 701 and the lower guide pipe 702, thereby avoiding material leakage.

[0034] In order to improve the reliability of the connection, a locking nut 804 is arranged on the supporting rod 802, the locking nut 804 is threadedly connected with the supporting rod 802, by arranging the locking nut 804 on the supporting rod 802 and pre-tightening relative to the connecting plate 801, the loosening is effectively prevented, and the reliability of the connection is improved.

[0035] The ring pipe chain conveyor, when working, continuously conveys raw materials through the feeding port 5, the driving member (motor) 6 drives the ring chain 4 in the four pipelines 1 to continuously convey through the rotating box, the adjacent chain plates 402 on the ring chain 4 and the pipelines 1 form a warehouse body conveying raw materials to lift the raw materials from the feeding port 5 to the discharging mechanism 6, the cover plate 603 is driven to rotate and open the discharge nozzle 601 through the actuator (cylinder) 604, the raw materials can fall through the discharge nozzle 601, compressed gas is sprayed into the gap of the discharge nozzle through the control of the pulse valve 602, the sticky materials attached on the ring chain 4 are blown into the discharge nozzle 601, after the raw material conveying is completed, the discharge nozzle 601 is closed through the actuator (cylinder) 604, the control of the pulse valve 602 sprays compressed gas into the gap of the discharge nozzle, the sticky materials attached on the ring chain 4 are blown into the discharge nozzle 601, and after a set time of work, the discharge nozzle 601 is opened, so that the ring chain 4 is self-cleaned.

[0036] In other embodiments, in order to adapt to higher processing capacity, with the increase of the length and diameter of the pipeline, the driving member is replaced by a hydraulic motor generating greater torque, so as to drive the ring chain 4 to work continuously and normally, of course, in order to adapt to the working condition, the actuator 604 can also be replaced by a hydraulic cylinder.

[0037] The utility model is not limited to the above specific implementation, and the ordinary skilled in the art can make various changes without creative labor based on the above concept, and all the changes fall within the protection scope of the utility model.
