DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0020] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0021] Example: Refer to Figure 1-3 The device realizes separation and screening of grain impurities and grains through a screening structure, and can also filter dust during the screening process. It also realizes rapid shaking during the screening process through a driving structure to increase the screening speed. The specific working principle is as follows: the staff pushes the device to move through the universal wheel 19 installed on the mounting plate 1, and stops after moving to the bottom of the grain conveying equipment. The grains enter the screening box 6 through the feed hopper 13, and the electric push rod 15 installed on the mounting seat 14 drives the screening box 6 through the first telescopic rod 16 to slide back and forth on the slide rail 3 through the slider 4 connected to the spring 5. The grains falling into the screening box 6 are screened through the screen 7, and the impurities are isolated at the top by the screen 7 and discharged through the first guide plate 8. The screened grains pass through the screen 7. The screen 7 falls down and is discharged through the second guide plate 9 for screening. During the screening process, the vibration motor 17 generates vibration, which makes the screening box 6 vibrate to improve the screening efficiency. At the same time, the spring 5 cooperates with the up and down vibration, and the first telescopic rod 16 and the second telescopic rod 18 extend and retract accordingly. The second telescopic rod 18 is used to limit the vibration direction of the screening box 6, which can only shake up and down. The roller 20 assists the second telescopic rod 18 to move left and right, thereby protecting the electric push rod 15. During the screening process, the fan 10 installed in the screening box 6 runs to extract the dust generated in the box, and the dust is filtered through the filter layer 12 in the filter box 11, thereby protecting the working environment and preventing the dust from attaching to the grains again. There is a protective net under the fan 10 to prevent the grains from entering the fan.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
