[0002] A screw conveyor is a machine that uses a motor to drive the screw to rotate and push materials to achieve the purpose of conveying. The screw conveyor can convey horizontally, inclined or vertically. It has the advantages of simple structure, small cross-sectional area and good sealing. In terms of conveying form, it is divided into shaft screw conveyors and shaftless screw conveyors. In terms of appearance, it is divided into U-type screw conveyors and tubular screw conveyors.

[0003] Screw conveyors are widely used in various industrial sectors. A spiral blade is installed inside the screw conveyor, and a rotating shaft for controlling the rotation of the spiral blade is installed outside. A feed port and a discharge port connected to the inner wall are opened on the outer wall. When working, materials are put into the feed port, and the rotating spiral blades push the materials from the feed port along the inner wall of the pipe to the discharge port, and then the materials are discharged from the discharge port to the outside of the screw conveyor.

A drive shaft 5 is installed at the output end of the drive motor 4. The drive motor 4 drives the drive shaft 5 to rotate, and the drive shaft 5 extends to the inside of the conveyor body 1. A spiral plate 6 is sleeved on the outer wall of the drive shaft 5. The drive shaft 5 drives the spiral plate 6 to rotate. A plurality of water inlets 10 are provided at the upper end of the conveyor body 1. A water conveying belt 9 is installed at the upper end of the conveyor body 1, and a water conveying belt 9 is installed at the upper end of the conveyor body 1. The belt 9 covers the upper ends of multiple groups of water inlets 10, and the inner walls of the multiple groups of water inlets 10 are all installed with baffles 11. Movable shafts 15 are movably installed on one side of the multiple groups of water inlets 10, and the multiple groups of movable shafts 15 are respectively movably connected with the multiple groups of baffles 11. Water wheels 17 are installed on the upper ends of the multiple groups of movable shafts 15. The water source drives the water wheel 17 to rotate, thereby driving the movable shaft 15 to rotate, and then driving the baffle 11 to move. A water collecting tank 7 is provided on one side of the conveyor body 1, and a water pump is provided inside the water collecting tank 7. A water pipe 8 is installed at the water outlet of the water collecting tank 7, and one end of the water pipe 8 is connected to the water conveying belt 9. The water collecting tank 7 introduces the water source into the water conveying belt 9 through the water pipe 8.

[0033] See also Figure 2 - Figure 4A limiting shaft 12 is movably installed on one side of multiple groups of water inlets 10, and the outer walls of multiple groups of limiting shafts 12 are provided with threaded grooves. The inner walls of multiple groups of baffles 11 are respectively threadedly connected with the outer walls of multiple groups of limiting shafts 12. A limiting bevel gear 13 is installed on one end of multiple groups of limiting shafts 12. When the limiting shaft 12 rotates, the inner wall of the baffle 11 is threadedly connected with the outer wall of the limiting shaft 12, thereby driving the baffle 11 to move.

[0034] See also Figure 2 - Figure 4 , the lower ends of the multiple groups of movable shafts 15 are all equipped with movable bevel gears 16, and the limiting bevel gears 13 and the movable bevel gears 16 are meshed and connected. The movable shaft 15 rotates, driving the movable bevel gears 16 to rotate, thereby driving the limiting bevel gears 13 to rotate, and then driving the limiting shaft 12 to rotate.

[0035] See also Figure 2 - Figure 4 A reset block 14 is installed at one end of each of the multiple limit shafts 12, and a torsion spring is arranged inside the reset block 14 and connected to one end of the limit shaft 12. When the water source is stopped, the reset block 14 drives the limit shaft 12 to reset and rotate, thereby driving the baffle 11 to move, and then closing the water inlet 10.

[0036] See also Figure 1 - Figure 5 A bellows 18 is provided at the lower end of the conveyor body 1 , and an air supply pipe 19 is installed at the air outlet of the bellows 18 , and the wind force generated inside the bellows 18 is discharged from the air supply pipe 19 .

[0037] See also Figure 1 - Figure 6 A linkage shaft 21 is movably installed inside the bellows 18, and the linkage shaft 21 is connected to the drive shaft 5 through a synchronous belt. A fan 22 is installed on the outer wall of the linkage shaft 21. When the drive shaft 5 rotates, since the drive shaft 5 and the linkage shaft 21 are connected through a synchronous belt, the linkage shaft 21 rotates, thereby driving the fan 22 to rotate.

[0038] See also Figure 1 - Figure 5 An air collecting plate 20 is obliquely installed at one end of the conveyor body 1, and a filter is provided at the air outlet of the air collecting plate 20. The air inlet of the air collecting plate 20 is connected to one end of the air supply pipe 19. The air flow flows from the air supply pipe 19 to the air collecting plate 20. The air collecting plate 20 discharges the air flow, thereby increasing the material discharge efficiency of the feed port 2 and avoiding blockage of the feed port 2. Secondly, it assists the internal cleaning operation of the conveyor body 1.

[0039] The working principle of the utility model is as follows: when the device is used for material conveying in daily life, the operator pours the material from the feed port 2 into one end of the conveyor body 1, starts the drive motor 4 to drive the drive shaft 5 and the spiral plate 6 to rotate, so that the material moves inside the conveyor body 1 and is discharged through the discharge port 3;

[0040] When the driving shaft 5 rotates, since the driving shaft 5 is connected to the linkage shaft 21 through a synchronous belt, the linkage shaft 21 rotates, thereby driving the fan 22 to rotate, so that airflow is generated inside the bellows 18, and the airflow flows from the air supply pipe 19 to the air collecting plate 20. The operator continues to pour the material from the feed port 2 into the conveyor body 1, and the air collecting plate 20 discharges the airflow, thereby increasing the material discharge efficiency of the feed port 2 and avoiding blockage of the feed port 2.

[0041] When cleaning the inside of the conveyor body 1, the water pump inside the water collecting tank 7 is started, and the water source is pumped into the water pipe 8 and conducted to the water conveying belt 9. When the water flows in the water conveying belt 9, the water wheel 17 is pushed to rotate the water wheel 17, thereby driving the movable shaft 15 to rotate, and then driving the movable bevel gear 16 to rotate, and the movable bevel gear 16 is meshed and connected with the limit bevel gear 13, so the limit bevel gear 13 rotates, thereby driving the limit shaft 12 to rotate, and then driving the baffle 11 to move, and the water inlet 10 is opened. The water source enters the inside of the conveyor body 1 through multiple groups of water inlets 10, and the inside of the conveyor body 1 is flushed and cleaned. At the same time, the spiral plates 6 in different areas are flushed and cleaned, and the internal cleaning effect of the screw conveyor 1 is further improved;

[0042] When the water source flushes the inside of the conveyor body 1, the wind collecting plate 20 discharges wind to assist the water source in cleaning the inside of the conveyor body 1, preventing some materials from sticking to the outer wall of the spiral plate 6, the outer wall of the drive shaft 5 and the inner wall of the conveyor body 1, further improving the cleaning effect of the inside of the screw conveyor 1. After the water source flushes the inside of the conveyor body 1, the wind dries the inside of the conveyor body 1, so that the screw conveyor can be put into use faster after the inside is cleaned.
