Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 In the embodiment of the present invention, a screw feeder includes a storage tank 1, a first power mechanism 3 and a screw feeder 5; the screw feeder 5 is installed on one side of the storage tank 1, a discharge pipe 4 is installed at the bottom end of the storage tank 1, and the bottom end of the discharge pipe 4 is installed at one side of the bottom end of the screw feeder 5. A feed hopper 2 is installed on one side of the upper end of the storage tank 1. A shaft rod 20 is installed inside the storage tank 1. A screw blade 15 is welded on the outer side of the section where the bottom end of the shaft rod 20 extends into the discharge pipe 4. Stirring blades 14 are installed at the upper and lower ends of the shaft rod 20. A plurality of steel wire ropes 13 are installed between the stirring blades 14. A scraper 12 is installed inside the storage tank 1, and the inner side of the scraper 12 is installed at the upper and lower ends of the shaft rod 20.

[0024] The screw feeder 5 is composed of a feeding cylinder 9, a second power mechanism 6 and a screw rod 19. The screw rod 19 is rotatably installed inside the feeding cylinder 9. The upper end of the screw rod 19 passes through the feeding cylinder 9 and is installed at the bottom end of the second power mechanism 6. The second power mechanism 6 is installed at the bottom end of the feeding cylinder 9. During the use of the screw feeder 5, the second power mechanism 6 drives the screw rod 19 to rotate. During the rotation of the screw rod 19, the materials inside the storage tank 1 are lifted upward to feed.

[0025] Both the first power mechanism 3 and the second power mechanism 6 are composed of a motor 17 and a transmission 18. The motor 17 is installed at the upper end of the transmission 18. When the first power mechanism 3 and the second power mechanism 6 are in use, power is provided by the motor 17, and the rotation speed is adjusted by the transmission 18 to provide power for the rotation of the shaft rod 20 and the screw rod 19.

[0026] A rubber pad 11 is provided on the outer side of the scraper 12. The rubber pad 11 is pasted on the outer side of the scraper 12 through an adhesive. The setting of the rubber pad 11 can increase the softness of the outer side of the scraper 12 and prevent the scraper 12 from wearing the inner wall of the storage tank 1 during use. One side of the upper and lower ends of the scraper 12 is installed on the upper side of the one-way bearing 16. The one-way bearing 16 is installed on the upper and lower sides of the shaft rod 20. During discharging, the shaft rod 20 rotates normally, the one-way bearing 16 is in an active state, and the scraper 12 does not move. When it is necessary to clean the inner wall of the storage tank 1, the one-way bearing 16 is locked, and the scraper 12 will move to clean the inner wall of the storage tank 1, avoiding a large resistance of the scraper 12 during the discharging process and affecting the discharging speed.

[0027] A flap 10 is provided at the upper end of the feed hopper 2. The flap 10 is rotatably installed at the upper end of the feed hopper 2. The setting of the flap 10 enables one side of the flap 10 to rotate due to uneven forces on both sides of the flap 10 during the process of adding materials, so that the materials can smoothly fall into the interior of the storage tank 1. After the feeding is completed, the flap 10 automatically closes due to gravity, preventing the material dust from being discharged from the feed hopper 2.

[0028] The working principle and usage process of the present utility model: When in use, the materials are introduced into the interior of the storage tank 1 through the feed hopper 2. Then, when discharging is required, the first power mechanism 3 and the second power mechanism 6 are turned on through a switch. The first power mechanism 3 will drive the shaft rod 20 to rotate. The shaft rod 20 drives the spiral blade 15 to introduce the materials in the storage tank 1 into the outlet pipe 4, and the materials are introduced into the spiral feeder 5 through the outlet pipe 4 and lifted upward by the spiral feeder 5. During the rotation of the shaft rod 20, on the one hand, it can drive the stirring blade 14 to stir the materials. During the stirring process of the stirring blade 14, the steel wire rope 13 can disperse the materials, facilitating the sinking of the materials and preventing the materials from accumulating and forming agglomerates, which are difficult to discharge. After the discharging is completed, when it is necessary to clean the interior of the storage tank 1, the scraper 12 is driven to move by the shaft rod 20, and the scraper 12 will clean the inner wall of the storage tank 1.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
