The huge consumption of plastics has brought about a large amount of plastic waste, but not all plastic waste will cause pollution problems. Most plastic materials are renewable. Recycling waste plastics can not only solve the problem of plastic pollution, but also provide considerable raw materials for industrial production, thereby reducing oil extraction. Traditional screw conveyors mostly adopt a single screw or double screw structure, which has problems such as low conveying efficiency, easy blockage, and poor adaptability. Therefore, those skilled in the art provide a three-screw conveying device with a star structure to solve the problems raised in the above background technology. Summary of the Invention

[0003] The purpose of the present invention is to provide a three-screw conveying device with a star-shaped structure to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: it includes a barrel, a feed port, a first conveying shaft, a second conveying shaft, a third conveying shaft, a spiral blade, a reducer, a driving sprocket, a driven sprocket, a chain and a discharge port; a feed port is provided on one end of the barrel, and a discharge port is provided at the bottom of the other end; the first conveying shaft, the second conveying shaft and the third conveying shaft are installed in the barrel, and the three conveying shafts are arranged in a star shape, the three conveying shafts are respectively provided with spiral blades, and the shaft ends of the three conveying shafts are respectively provided with driven sprockets, and a driving sprocket is installed on the output shaft of the reducer, and the driving sprocket is connected to the three driven sprockets by a chain.

[0005] Furthermore, the barrel is fixed on the first frame and the second frame.

[0006] Furthermore, the feed port is a cone-shaped structure.

[0007] Furthermore, the reducer is mounted on the barrel via a mounting plate.

[0008] After adopting the above structure, the beneficial effects produced by the present invention are as follows: the triple-screw conveying device with a star-shaped structure described in the present invention adopts a triple-screw structure to increase the contact area of ​​the material and the stirring effect during the conveying process, thereby improving the conveying efficiency and stability, and is particularly suitable for continuous conveying operations of powdered, granular and block materials.

[0012] Barrel 1, feed port 2, first conveyor shaft 3, second conveyor shaft 4, third conveyor shaft 5, spiral blade 6, reducer 7, driving sprocket 8, driven sprocket 9, chain 10, discharge port 11, first frame 12, second frame 13, mounting plate 14. DETAILED DESCRIPTION

[0013] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0014] See Figure 1 —— Figure 2 As shown, this specific embodiment adopts the following technical scheme: it includes a barrel 1, a feed port 2, a first conveying shaft 3, a second conveying shaft 4, a third conveying shaft 5, a spiral blade 6, a reducer 7, a driving sprocket 8, a driven sprocket 9, a chain 10 and a discharge port 11; the barrel 1 is fixed on a first frame 12 and a second frame 13, and there is a height difference between the first frame 12 and the second frame 13. The barrel 1 is in an inclined state with one end high and the other end low, which is suitable for conveying materials at two places at different heights. A feed port 2 is provided on one end of the barrel 1, and the feed port 2 is a conical structure for easy loading, and a discharge port 11 is provided at the bottom of the other end.

[0015] A first conveying shaft 3, a second conveying shaft 4 and a third conveying shaft 5 are installed in the barrel 1, and the three conveying shafts are arranged in a star shape. Spiral blades 6 are respectively provided on the three conveying shafts. Driven sprockets 9 are respectively installed on the shaft ends of the three conveying shafts. A driving sprocket 8 is installed on the output shaft of the reducer 7. The driving sprocket 8 and the three driven sprockets 9 are connected by a chain 10. The reducer 7 is installed on the barrel 1 through the mounting plate 14. The three conveying shafts are driven by the reducer 7 to rotate synchronously. The three conveying shafts and the spiral blades 6 constitute a triple helical structure. The rotation of the triple helical structure increases the contact area and stirring effect of the material, reduces the blockage phenomenon, and the synchronously rotating triple helical structure can balance the force on the material, thereby reducing vibration and noise and enhancing stability.

[0016] The working principle of the utility model is as follows: the material enters the barrel 1 from the feed port 2, moves along the axial direction of the barrel 1 under the push of the spiral blades 6 on the three conveying shafts, realizes continuous conveying, and is finally conveyed to the discharge port 11 and falls into the next equipment.

[0017] The above shows and describes the basic principles and main features of the present invention, as well as the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
