It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] Example: Figure 1-4 As shown, the utility model provides an energy-saving and efficient mixing bin feeder technical solution, including a mixing bin 1, a feeding pipe 2 is arranged at the bottom of the mixing bin 1, a rotating rod 3 is rotatably installed in the middle of the feeding pipe 2, a driving motor 4 is installed on one side of the feeding pipe 2, the output end of the driving motor 4 is connected to one end of the rotating rod 3, and a stirring blade 5 is evenly welded in the middle of the outer side of the rotating rod 3;

[0024] The input end of the driving motor 4 is electrically connected to the output end of the external power supply. When the driving motor 4 is started, it can drive the rotating rod 3 and the stirring blade 5 to rotate to prevent the material from being blocked inside the discharge pipe 2. At the same time, the stirring of the stirring blade 5 can make the discharge speed faster.

[0025] The other end of the rotating rod 3 is connected to a driving bevel gear 6, and a driven bevel gear 7 is rotatably installed at the bottom of the driving bevel gear 6 on one side of the feeding tube 2. The bottom of the driven bevel gear 7 is connected to a driving gear 8. A bidirectional screw rod 9 is rotatably installed on one side of the feeding tube 2, and a driven gear 10 is fixedly connected to the middle of the outer side of the bidirectional screw rod 9, and the driving gear 8 and the driven gear 10 are meshed with each other;

[0026] Movable grooves 11 are provided at both ends of one side of the feeding tube 2, and sealing plates 12 are slidably installed inside the movable grooves 11. A connecting ear 13 is connected to one side of the sealing plate 12, and the connecting ear 13 is respectively connected to the two ends of the adjacent bidirectional screw rod 9. Moving openings 21 are provided on both sides of the movable groove 11, and the connecting ear 13 passes through the moving opening 21. A scraper ring 14 is connected to the other side of the sealing plate 12;

[0027] The inner side of the movable groove 11 is tightly fitted with the outer side of the sealing plate 12, and the sealing plate 12 can isolate the material in the feeding pipe 2 to prevent the material from entering the movable groove 11 and hindering the up and down movement of the sealing plate 12. At the same time, the inner side of the movable groove 11 and the outer side of the sealing plate 12 are both smooth curved surfaces, so that the friction resistance between the movable groove 11 and the sealing plate 12 is reduced, so that the sealing plate 12 can move more smoothly inside the movable groove 11;

[0028] The outer side of the scraper ring 14 is tightly fitted with the inner wall of the discharge pipe 2. Under the limiting action of the sealing plate 12 and the movable groove 11, the bidirectional screw rod 9 rotates back and forth to drive the connecting ear 13 to move up and down along the movable opening 21, thereby driving the scraper ring 14 to move up and down inside the discharge pipe 2. The outer side of the scraper ring 14 is tightly fitted with the inner wall of the discharge pipe 2, and the scraper ring 14 can clean the material adhered to the inner wall of the discharge pipe 2.

[0029] A water channel 15 is provided inside the connecting ear 13, a water pipe 16 is connected to one side of the connecting ear 13, a connecting channel 17 is provided on one side of the scraper ring 14, the connecting channel 17 is connected to the water channel 15, water grooves 18 are provided at the top and bottom of the scraper ring 14, both ends of the connecting channel 17 are connected to adjacent water grooves 18, a sealing ring 19 is connected to the top and bottom of the scraper ring 14, water spray holes 20 are evenly arranged on the top of the sealing ring 19, and a one-way valve is embedded in the water spray hole 20 to prevent materials from entering the water groove 18;

[0030] The water pipe 16 is connected to the water outlet end of the external water pump. When the material is discharged from the mixing bin 1, the external water pump introduces clean water into the water pipe 16. The clean water flows through the water channel 15 and the connecting channel 17 in sequence and enters the water trough 18, and finally sprays out from the water spray hole 20. The water outlet end of the water spray hole 20 faces the inner wall of the discharge pipe 2. The sprayed clean water cooperates with the up and down movement of the scraper ring 14 to remove the material on the inner wall of the discharge pipe 2, so that the cleaning effect is better.

[0031] The working principle and use process of the utility model are as follows: the material is fed into the mixing bin 1, and after being stirred by the mixing bin 1, it falls into the discharge pipe 2, and the driving motor 4 is started, and the driving motor 4 drives the rotating rod 3 and the stirring blade 5 to rotate, and the material is prevented from being blocked in the discharge pipe 2 under the push of the stirring blade 5. At the same time, the stirring of the stirring blade 5 can make the discharge speed faster;

[0033] When the material is discharged from the mixing bin 1, the external water pump is started, and the external water pump introduces clean water into the water pipe 16. The clean water flows through the water channel 15 and the connecting channel 17 in sequence and enters the water trough 18, and finally sprays out from the water spray hole 20. The water outlet end of the water spray hole 20 faces the inner wall of the discharge pipe 2. The sprayed clean water cooperates with the up and down movement of the scraper ring 14 to remove the material on the inner wall of the discharge pipe 2, so that the cleaning effect is better.
