DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1-5, the present utility model provides a technical solution: a feed chute device for a powder separator, including an aggregate bucket 1, a large scraper 2, a small scraper 3, a first connecting rod 4, a first motor 5, a second motor 6, a second connecting rod 7, a screw rod 8, a discharge chute 9, a cover plate 10, a storage pipe 11, a solenoid valve 12, a connecting pipe 13, a water tank 14, a rotary cap 15, a first water pipe 16, a second water pipe 17, and a spray head 18.

[0027] The small scraper 3 is arranged at the lower end of the large scraper 2. The inside of the small scraper 3 is connected with a first connecting rod 4, and the upper end of the first connecting rod 4 is connected with a first motor 5. And a second motor 6 is installed at the upper end of the first motor 5. The left end of the second motor 6 is connected with a second connecting rod 7, and the lower end of the second connecting rod 7 is installed with a screw rod 8. And a discharge chute 9 is arranged outside the screw rod 8;

[0028] The cover plate 10 is installed at the upper end of the aggregate bucket 1. A storage pipe 11 is installed at the upper end of the cover plate 10. And the lower end of the storage pipe 11 is connected with a connecting pipe 13. And a solenoid valve 12 is arranged outside the connecting pipe 13. A water tank 14 is installed inside the connecting pipe 13. And a rotary cap 15 is installed at the upper end of the water tank 14. And the lower end of the water tank 14 is connected with a first water pipe 16 and a second water pipe 17. The first water pipe 16 is arranged at the right end of the second water pipe 17. And spray heads 18 are installed at the lower ends of both the first water pipe 16 and the second water pipe 17.

[0029] As Figure 1 , Figure 2 and Figure 4 shown, the large scraper 2 is symmetrically arranged about the central axis of the first connecting rod 4. And the upper end of the first connecting rod 4 is connected with the first motor 5 in a meshing manner. Four small scrapers 3 are symmetrically arranged about the central axis of the first connecting rod 4. And the outer surfaces of the large scraper 2 and the small scrapers 3 are in contact with the inner wall of the aggregate bucket 1. The upper end of the second connecting rod 7 is connected with the second motor 6 in a meshing manner. And the lower end of the second connecting rod 7 is fixedly connected with the screw rod 8. And the second connecting rod 7 penetrates through the inside of the first connecting rod 4. When using this feeding device, first insert the storage pipe 11 into the upper end of the aggregate bucket 1 through the connecting pipe 13 and start the solenoid valve 12 to make the dry powder fall into the inside of the aggregate bucket 1. Then start the first motor 5 and the second motor 6. Then the left end of the first motor 5 drives the first connecting rod 4 to rotate. Since the outer ends of the first connecting rod 4 are fixedly connected with the large scraper 2 and the small scrapers 3, the large scraper 2 and the small scrapers 3 rotate synchronously to stir the dry powder in the aggregate bucket 1, which can effectively prevent the material from caking, thereby maintaining the stability and fluidity of the material. And the dry powder inside the aggregate bucket 1 will enter the discharge chute 9 along with the screw rod 8 and fall out evenly under the push of the screw rod 8, which is convenient to push the powder into the powder separator. And the setting of the four storage pipes 11 can greatly increase the feeding rate, thereby improving the working efficiency of the powder separator.

[0030] As Figure 1 , Figure 3 and Figure 5 shown, the connecting pipe 13 penetrates through the inside of the cover plate 10, and there are 4 connecting pipes 13 symmetrically arranged about the central axis of the cover plate 10. The screw cap 15 is connected to the upper end of the water tank 14 by means of threads, and the lower end of the water tank 14 is fixedly connected with a first water pipe 16 and a second water pipe 17. When the device needs to be cleaned, the powder in the device can be emptied first, and the first motor 5 is started alone, so that the left end of the first motor 5 drives the first connecting rod 4 to rotate, then the large scraper 2 and the small scraper 3 rotate in contact with the inner wall of the aggregate bucket 1. At the same time, the spray head 18 is started, so that the upper end of the spray head 18 extracts the cleaning agent from the inside of the water tank 14 through the first water pipe 16 and the second water pipe 17 for spraying. The cleaning agent cooperates with the scraper to facilitate improving the cleaning degree inside the device.
