DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the schematic embodiments of the present invention and their description are used to explain the present invention, but are not intended to limit the present invention. Example 1

[0022] Reference Figures 1-4 A screw conveyor for uniform material delivery includes a screw conveyor housing 1. A feed pipe 11 is fixed to one end of the screw conveyor housing 1. The end of the feed pipe 11 away from the screw conveyor housing 1 is connected to a centrifuge. A storage box 2 is fixed to the side of the screw conveyor housing 1 away from the feed pipe 11. The storage box 2 and the feed pipe 11 are both located above the screw conveyor housing 1 and communicate with the interior of the screw conveyor housing 1. A conveying shaft 12 is provided inside the screw conveyor housing 1, and a spiral conveying blade 13 is fixed to the conveying shaft 12.

[0023] A material discharge box 3 is fixed below the screw conveyor housing 1 , and the material discharge box 3 is communicated with the interior of the screw conveyor housing 1 . A material discharge assembly 4 is provided inside the material discharge box 3 , and the material discharge assembly 4 can control the uniformity of the material discharge.

[0024] The top wall of the screw conveyor housing 1 is provided with a cover plate 16, which is hingedly connected to the top wall of the screw conveyor housing 1. A first locking catch 17 is provided on the other side of the cover plate 16, and the cover plate 16 is fixed to the top wall of the screw conveyor housing 1 via the first locking catch 17. Opening the cover plate 16 allows the interior of the screw conveyor housing 1 to be viewed. A transparent plate 21 made of acrylic is bolted to the side wall of the storage box 2. The interior of the storage box 2 can be viewed through the transparent plate 21. A top plate 22 is installed on the top of the storage box 2, and the top plate 22 can be fixed to the storage box 2 via bolts.

[0025] The unloading assembly 4 includes two parallel threaded rods 41. The length direction of the threaded rod 41 is arranged along the length direction of the screw conveyor housing 1. The threaded rod 41 is rotatably connected to the side wall of the unloading box 3. One end of the threaded rod 41 extends out of the side wall of the unloading box 3. A driving assembly 5 is provided on one side of the unloading box 3 to drive the two threaded rods 41 to rotate simultaneously.

[0026] A bottom plate 15 is installed at the connection point between the discharge box 3 and the screw conveyor housing 1. The bottom plate 15 is fixed to the screw conveyor housing 1 and has two discharge chutes 151. The material inside the screw conveyor housing 1 falls into the discharge box 3 through the discharge chutes 151. Two partitions 42 are provided between the two threaded rods 41, each partition 42 corresponding to a discharge chute 151.

[0027] Connecting rods 431 are fixed to both sides of the partition 42. Connecting nuts 43 are fixed to the bottom of the connecting rods 431, which are threadedly connected to the threaded rods 41. When the threaded rods 41 are rotated, the connecting nuts 43 move along the length of the threaded rods 41, thereby driving the connecting rods 431 and the partitions 42 to move. The two partitions 42 can move along the length of the threaded rods 41, thereby adjusting the gap in the feed chute 151 and controlling the uniformity of the feed. Crushing teeth 14 are fixed to the inner wall of the base plate 15 and the circumferential wall of the conveyor shaft 12. These teeth 14 break up large chunks of raw salt. A door panel 31 is hinged to the side wall of the feed box 3. A second lock 32 is attached to the door panel 31, securing it to the side wall of the feed box 3. The door panel 31 is made of transparent acrylic.

[0028] The drive assembly 5 includes two sprockets 51, each corresponding to a threaded rod 41, and the sprockets 51 are fixedly connected to the threaded rod 41. The two sprockets 51 are connected by a chain 52. A driving member 53 is connected to one of the sprockets 51, and the driving member 53 can drive the sprocket 51 to rotate. The driving member 53 can be a manual rocker or a motor.

[0029] The principle of the screw conveyor for uniform feeding of the present invention is as follows: raw salt enters the screw conveyor housing 1 through the feed pipe 11, and the screw conveyor conveys the raw salt to one side of the feeding box 3. When a large amount of raw salt flows into the screw conveyor, some raw salt will be stored in the storage box 2. When normal feeding is restored, the raw salt in the storage box 2 falls to the screw conveyor by its own gravity and falls from the feeding box 3. The setting of the feeding assembly 4 in the feeding box 3 can adjust the feeding gap of the feeding chute 151 and control the uniformity of feeding. Example 2

[0030] Reference Figure 5 The difference from the embodiment is that a vibration motor 23 is fixed to the side wall of the storage box 2. When the raw salt in the storage box 2 falls, the vibration motor 23 is activated, accelerating the fall of the raw salt in the storage box 2. A rotating shaft 25 is fixed to the top side wall of the storage box 2. One end of the top plate 22 is hinged to the rotating shaft 25. An additional hopper 24 is fixed to the outer wall of the storage box 2. The additional hopper 24 is located on the side of the top plate 22 away from the rotating shaft 25 and is located below the top plate 22. When the raw salt fills the storage box 2, it will press the top plate 22 upward, and some of the raw salt will flow out of the top of the storage box 2 and into the additional hopper 24.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
