[0024] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0025] Reference Figures 1 to 4 This application provides a grain separation and screening device for the production of compound instant powder, including a screening box 1. A support leg 4 is fixedly installed at the bottom of the screening box 1. A screening component 2 is disposed inside the screening box 1, and an auxiliary component 3 is disposed inside the screening component 2. A conical hopper 7 is fixedly installed at the bottom of the screening box 1. The screening component 2 includes a main screen 25, which is fixedly installed at the connection between the screening box 1 and the conical hopper 7. A bracket 21 is fixedly installed on the outside of the screening box 1. A rotating rod 23 is fixedly installed at the top center of the main screen 25, and a partition 24 is fixedly installed on the outside of the rotating rod 23. The outer edge of the partition 24 is attached to the inner wall of the screening box 1, and the two partitions 24 are arranged at a 90-degree angle. A first motor 22 is fixedly installed on the top of the bracket 21, and the output end of the first motor 22 movably passes through the inside of the bracket 21. The output end of the first motor 22 is fixedly installed on the top of the rotating rod 23. The main screen 25 is circular and consists of four quarter screens, each of the same size, with the aperture of the screens increasing sequentially.
[0026] In this embodiment, when the grain is sieved, it is placed between two partitions 24 inside the sieve box 1. The two partitions 24 are located above the separation of two screens, ensuring that there is a complete screen between the two partitions 24. Sieving is performed through the screen. After one screen is sieved, the first motor 22 is started to drive the rotating rod 23 to rotate. The rotation of the rotating rod 23 can move the partitions 24 and the grain inside. Rotating the partitions 24 by 90 degrees can move the grain above the next screen. The aperture of this screen is larger than that of the previous screen. Repeating this three times can completely sieve the grain through four screens. The order of passing through the screens is from small aperture to large aperture, thus realizing multi-stage sieving of the grain. Each stage of sieving is repeated before entering the next screen, thus ensuring the integrity of the sieving. After each stage of sieving, the sieved grain falls into the conical hopper 7, and the solenoid valve 5 is opened for collection, ensuring the collection of grain. The aperture of the largest screen is larger than the diameter of the grain, so that all the grains of the largest grade can be completely discharged during the last movement.
[0027] Reference Figures 1 to 4 In one aspect of this embodiment, the auxiliary component 3 includes a horizontal plate 31, which is fixedly installed on the outside of the rotating rod 23. A rotating rod 33 is rotatably connected to the bottom of the horizontal plate 31. A stirring rod 34 and a lever 35 are fixedly installed on the outside of the rotating rod 33. The lever 35 is attached to the top of the main screen 25.
[0028] A second motor 32 is fixedly installed on the top of the horizontal plate 31. The output end of the second motor 32 moves through the interior of the horizontal plate 31 and is fixedly connected to the rotating rod 33 below. The rotating rod 33, the stirring rod 34, and the lever 35 are all located between the two partitions 24.
[0029] A solenoid valve 5 is fixedly installed at the bottom of the conical hopper 7, and a vibration motor 6 is fixedly installed at the bottom of the conical hopper 7. The vibration motor 6 is located below the corresponding screen.
[0030] In this embodiment, during sieving, the vibration motor 6 below the corresponding screen is activated to assist in sieving. The second motor 32 is activated to drive the rotating rod 33 to rotate. The rotation of the rotating rod 33 drives the stirring rod 34 and the lever 35 to rotate. The stirring rod 34 and the lever 35 agitate the grain inside, and together with the vibration motor 6, the grain can be completely sieved. The stirring rod 34 and the lever 35 follow the rotation of the horizontal plate 31 and the rotating rod 23 above, ensuring that the stirring rod 34 and the lever 35 can assist in each sieving.
[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0032] Working principle: During grain separation and screening, the grain is first placed inside the screening box 1 between two partitions 24 arranged at ninety degrees. At this time, the two partitions 24 are located above the separation points of the two screens, ensuring that there is a complete screen between the two partitions 24. The vibration motor 6 below the corresponding screen is started to assist in screening. At the same time, the second motor 32 is started, and its output end drives the rotating rod 33 to rotate, which in turn causes the stirring rod 34 and the lever 35 fixed outside the rotating rod 33 to rotate, stirring the grain between the two partitions 24. This, together with the vibration motor 6, achieves preliminary screening. After one screen is screened, the first motor 22 is started, and its output end drives the rotating rod 23 to rotate, thereby moving the partitions 24 and the grain inside. The partitions 24 are rotated ninety degrees, so that the grain moves above the next screen with a larger aperture. The above screening operation is repeated. After three rotations, the grain is completely screened through four screens. The screened grain falls into the conical hopper 7. After each screen is screened, the solenoid valve 5 is opened for collection, thus completing the multi-stage screening of the grain.
