[0019] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1 to 3 , a screening and impurity-removing device for highland barley raw grains in this embodiment, includes a screening box 1. A screening mechanism is provided on the screening box 1. The screening mechanism includes an air box 2 fixedly installed on the top of the screening box 1. A filter core 3 and a fan 4 are arranged inside the air box 2. An air outlet 5 extending into the screening box 1 is provided at the bottom of the air box 2. Two air outlet pipes 9 are fixedly installed between the air outlet 5 and the bottom of the air box 2. The air outlet pipes 9 extend into the screening box 1. The air outlet 5 is directly above the separation grid cylinder 6. A separation grid cylinder 6 is rotatably installed inside the screening box 1. A rectangular discharge port 10 is fixedly installed on the surface of the separation grid cylinder 6. A plurality of stirring rods 11 are fixedly installed on the inner surface of the separation grid cylinder 6. The plurality of stirring rods 11 are evenly distributed on the inner surface of the separation grid cylinder 6. One end of the separation grid cylinder 6 is fixedly installed with a support connection pipe 7 penetrating outside the screening box 1. One end of the support connection pipe 7 is rotatably installed with a connection elbow 8 communicated with the air box 2. A dust collection box 12 is clamped inside the screening box 1. The dust collection box 12 is directly below the separation grid cylinder 6.
[0021] A driving mechanism for driving the separation grid cylinder 6 to rotate is provided on the screening box 1. The driving mechanism includes a motor 13 fixedly installed on the outer surface of the screening box 1. The output end of the motor 13 is fixedly installed with a rotating shaft 14 penetrating into the screening box 1. One end of the rotating shaft 14 away from the motor 13 is fixedly connected to the surface of one end of the separation grid cylinder 6. A fixing frame 15 is fixedly installed on the outer surface of the motor 13. The fixing frame 15 is fixedly connected to the outer surface of the screening box 1.
[0022] The surface of the separation grid cylinder 6 in this embodiment is a mesh structure, and the aperture of the mesh is smaller than the diameter of highland barley grains.
[0023] It should be noted that the rectangular discharge port 10 in this embodiment is a rectangular sleeve with a switch closing function, which is convenient for putting or taking out highland barley from the separation grid cylinder 6.
[0024] It should be noted that the front surface and the bottom of the screening box 1 in this embodiment are open structures.
[0025] It should be noted that the top of the air box 2 in this embodiment is provided with a switchable and sealable box cover.
[0026] It should be noted that the filter core 3 in this embodiment is barrel-shaped and is directly above the fan 4.
[0027] The working principle of the above embodiment is as follows:
[0028] During use, the highland barley is put into the separation grid cylinder 6 through the rectangular discharge port 10. Start the motor 13, and the motor 13 drives the rotating shaft 14 and the separation grid cylinder 6 to rotate. The lever 11 can be used to stir the highland barley in the separation grid cylinder 6. Start the blower 4, and the blower 4 evacuates the air in the support connecting pipe 7 through the connecting elbow 8, so that a negative pressure is formed inside the support connecting pipe 7. Since the weight of some debris is lighter than that of the highland barley grains, the impurities with lighter weight will be sucked into the support connecting pipe 7, and finally sent into the filter element 3 through the connecting elbow 8 for filtration. The filtered air enters the air outlet 5 through the air outlet pipe 9, and acts on the surface of the separation grid cylinder 6 through the air outlet 5, which can blow the debris in the separation grid cylinder 6 to float, facilitating the separation of the highland barley from the impurities.
