[0002] Highland barley, an important highland cereal crop, is rich in dietary fiber. Its nutritional content is higher than that of rice, wheat, and corn, and it is characterized by high protein and low fat.

[0003] For example, Chinese patent CN221537263U discloses a barley grain impurity removal device, which includes a frame, a screening box, and a vibration mechanism. The screening box is connected to the frame, and two layers of screens are fixedly connected inside the screening box. The two layers of screens are spaced apart along the height direction of the screening box. The mesh diameter of the upper screen is equal to the diameter of the barley grain, and the diameter of the lower screen is smaller than the diameter of the barley grain. The vibration mechanism is connected to the screening box and is used to drive the screening box to vibrate. This application has the effect of improving the efficiency of barley grain screening and impurity removal.

[0004] The aforementioned patent has the following problems: This patent has some drawbacks in its use, such as: the device tends to generate a lot of dust during screening, and the inlet and outlet of the device are not sealed, which causes dust to drift into the working area and affect the working environment. At the same time, the device uses two drive motors and an air pump to avoid screen clogging, which increases the overall manufacturing cost of the device and consumes more electricity. Therefore, a barley rice impurity removal device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a barley rice impurity removal device in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A barley cleaning device includes an exhaust fan and a housing. A storage shell is fixedly installed on the top of the housing, and a U-shaped plate is fixedly installed inside the storage shell. An electric push rod is fixedly installed on the top of the storage shell. The output end of the electric push rod passes through the storage shell and the U-shaped plate and is fixedly installed with a baffle. A sealing cover is inserted into the inlet of the storage shell. An exhaust assembly is provided on the housing. Two side grooves are opened on both inner walls of the housing. A slider is slidably installed in the side groove. A telescopic rod fixed to the inner wall of the side groove is fixedly installed on the slider. A spring is sleeved on the telescopic rod. A U-shaped frame is fixedly installed between the four sliders. A first screening plate and a second screening plate are fixedly installed in the U-shaped frame. A collection box is inserted into the housing. A drive assembly for driving the displacement of the U-shaped frame is provided inside the housing.

[0007] Furthermore, the exhaust assembly includes an exhaust fan, which is fixedly installed on the top of the housing and located on one side of the storage shell. A U-shaped frame is fixedly installed on the top of the inner cavity of the housing and below the exhaust fan. A filter screen is fixedly installed inside the U-shaped frame. An air inlet is opened on the top of the housing, and a dustproof screen is fixedly installed inside the air inlet.

[0008] Furthermore, the drive assembly includes a fixed plate, which is fixedly installed at the bottom of the U-shaped frame. A rotating roller is rotatably installed inside the housing and located at the bottom of the fixed plate. A drive motor is fixedly installed on one side of the housing, and one end of the drive motor passes through one side of the housing and is coaxially connected to the rotating roller.

[0009] Furthermore, the output shaft of the drive motor is rotatably connected to the housing, the rotating roller has an elliptical structure, and the bottom of the fixed plate is parallel to the bottom of the housing.

[0010] Furthermore, the output shaft of the electric push rod is slidably connected to the storage shell and the U-shaped plate, the baffle is slidably connected to the U-shaped plate, and the bottom of the baffle is located inside the feed inlet of the shell.

[0011] Furthermore, the two ends of the spring are tightly welded to the top of the slider and the top of the side groove, respectively, and a guide plate is fixedly installed at the bottom of the U-shaped frame, the guide plate being located above one of the grooves inside the collection box.

[0012] The beneficial effects of this utility model are as follows: 1. This barley cleaning device, through the cooperation of the side groove, slider, telescopic rod, spring, U-shaped frame and drive assembly, allows the rotating roller to repeatedly and rapidly impact the U-shaped frame to move up and down, thereby generating large vibrations.

[0020] like Figures 1 to 5 As shown, a barley cleaning device includes an exhaust fan 6 and a housing 1. A storage shell 2 is fixedly installed on the top of the housing 1. A U-shaped plate 8 is fixedly installed inside the storage shell 2. An electric push rod 3 is fixedly installed on the top of the storage shell 2. The output end of the electric push rod 3 passes through the storage shell 2 and the U-shaped plate 8 and is fixedly fitted with a baffle 9. A sealing cover 4 is inserted into the feed inlet of the storage shell 2. An exhaust assembly is provided on the housing 1. Figure 1 and Figure 2 As shown, the exhaust assembly includes an exhaust fan 6, which is fixedly installed on the top of the outer casing 1 and located on one side of the storage shell 2. A U-shaped frame 13 is fixedly installed on the top of the inner cavity of the outer casing 1 and below the exhaust fan 6. A filter screen 14 is fixedly installed inside the U-shaped frame 13. An air inlet is opened on the top of the outer casing 1, and a dustproof screen is fixedly installed inside the air inlet.

[0021] More specifically, during use, the operator can place all the barley grains requiring impurities into the storage shell 2, then place the sealing cap 4 over the inlet of the storage shell 2. Next, the electric push rod 3 can be energized and started. The output shaft of the electric push rod 3 will drive the baffle 9 upwards, causing the baffle 9 to move out of the inlet of the outer shell 1. At this time, the outlet of the sealing cap 4 will connect with the inlet of the outer shell 1. The baffle 9 can control the flow rate of the barley grains in the storage shell 2, and then the barley grains will flow onto the first screening plate 10. Simultaneously, the exhaust fan 6 can be energized and started, and the contents of the outer shell 1 will be filtered. The air is exhausted to the outside, and the outside air will enter the housing 1 through the air inlet on the top of the housing 1. The air inlet is equipped with a dust filter, so the outside dust will not enter the housing 1 and the dust inside the housing 1 will not drift to the outside. Under the action of the filter 14, the dust and some light impurities generated inside the housing 1 can be blocked. When the whole device is finished operating, the dust and impurities attached to the filter 14 can fall into another groove in the collection box 5 and be collected. This process will not cause dust to drift into the working area, thus avoiding affecting the working environment.

[0022] Two side grooves 15 are formed on the inner walls of both sides of the outer casing 1. A slider 16 is slidably installed in the side groove 15. A telescopic rod 17, which is fixed to the inner wall of the side groove 15, is fixedly installed on the slider 16. A spring 18 is sleeved on the telescopic rod 17. A U-shaped frame 7 is fixedly installed between the four sliders 16. A first screening plate 10 and a second screening plate 11 are fixedly installed in the U-shaped frame 7. A collection box 5 is inserted into the outer casing 1. A drive assembly for driving the displacement of the U-shaped frame 7 is provided inside the outer casing 1. Figure 5 As shown, the drive assembly includes a fixed plate 21, which is fixedly installed at the bottom of the U-shaped frame 7. A rotating roller 12 is rotatably installed inside the housing 1 and located at the bottom of the fixed plate 21. A drive motor 19 is fixedly installed on one side of the housing 1, and one end of the drive motor 19 passes through one side of the housing 1 and is coaxially connected to the rotating roller 12.

[0023] More specifically, when the drive motor 19 is powered on and started, the output shaft of the drive motor 19 will drive the rotating roller 12 to rotate. During the rotation, the rotating roller 12 will squeeze the fixed plate 21 to move upward. The fixed plate 21 will drive the U-shaped frame 7 to move upward. The U-shaped frame 7 will drive the four sliders 16 to move upward. At this time, the telescopic rod 17 and the spring 18 will contract due to the compression of the sliders 16. Then, under the action of the rebound force of the spring 18, the spring 18 will drive the slider 16 to move downward. The slider 16 will drive the U-shaped frame 7 to move downward. The rotating roller 12 rotates repeatedly, thereby causing the U-shaped frame 7 to vibrate. At this time, the first screening plate 10 and the second screening plate 11 will vibrate and screen the barley.

[0024] like Figure 5 As shown, the output shaft of the drive motor 19 is rotatably connected to the outer casing 1, the rotating roller 12 has an elliptical structure, and the bottom of the fixed plate 21 is parallel to the bottom of the outer casing 1.

[0025] More specifically, this ensures that the output shaft of the drive motor 19 can rotate normally within the housing 1, and that the rotating roller 12 can squeeze the fixed plate 21 to cause displacement when rotating.

[0026] like Figure 2 As shown, the output shaft of the electric push rod 3 is slidably connected to the storage shell 2 and the U-shaped plate 8, the baffle 9 is slidably connected to the U-shaped plate 8, and the bottom of the baffle 9 is located inside the feed inlet of the shell 1.

[0027] More specifically, this ensures that the output shaft of the electric push rod 3 can slide normally, that the baffle 9 can slide within the U-shaped plate 8, and that the baffle 9 can seal the outlet of the sealing cover 4.

[0028] like Figure 4 and Figure 5As shown, the two ends of the spring 18 are tightly welded to the top of the slider 16 and the top of the side groove 15, respectively. A guide plate 20 is fixedly installed at the bottom of the U-shaped frame 7. The guide plate 20 is located above one of the grooves in the collection box 5.

[0029] More specifically, to ensure the structural stability of the spring 18, under the action of the guide plate 20, it is possible to guide the last barley grains screened on the second screening plate 11 so that they can enter one of the grooves in the collection box 5.

[0030] In summary: During use, the operator can place all the barley grains requiring impurity removal into the storage shell 2, then place the sealing cap 4 over the inlet of the storage shell 2. The drive motor 19 can then be powered on and started. The output shaft of the drive motor 19 will drive the rotating roller 12 to rotate. During rotation, the rotating roller 12 will press the fixed plate 21 upwards, which in turn will cause the U-shaped frame 7 to move upwards. The U-shaped frame 7 will then cause the four sliders 16 to move upwards. At this time, the telescopic rod 17 and the spring 18 will contract under the pressure of the sliders 16. Subsequently, under the rebound force of the spring 18, the spring 18 will cause the sliders 16 to move downwards, which in turn will cause the U-shaped frame 7 to move downwards. The rotating roller 12 rotates repeatedly, thereby achieving… The U-shaped frame 7 vibrates, and then the electric push rod 3 is energized and started. The output shaft of the electric push rod 3 will drive the baffle 9 to move upward, so that the baffle 9 moves out of the feed inlet of the outer shell 1. At this time, the discharge port of the sealing cover 4 will be connected to the feed inlet of the outer shell 1. The baffle 9 can control the flow rate of barley in the storage shell 2. Then the barley will flow into the first screening plate 10. Under the action of vibration, the barley and some small impurities will fall onto the second screening plate 11. Then the barley will fall into one of the grooves in the collection box 5. At this time, the large impurities will move on the first screening plate 10 and fall into another groove in the collection box 5. The small impurities on the second screening plate 11 will also fall into another groove in the collection box 5. Then, the exhaust fan 6 can be powered on and started, and the air inside the outer casing 1 will be exhausted to the outside. Outside air will enter the outer casing 1 through the air inlet at the top of the outer casing 1. The air inlet is equipped with a dust filter, so outside dust will not enter the outer casing 1 and the dust inside the outer casing 1 will not drift to the outside. Under the action of the filter screen 14, the dust and some lighter impurities generated inside the outer casing 1 can be blocked. When the whole device is running, the dust and impurities attached to the filter screen 14 can fall into another groove in the collection box 5 and be collected. During this process, no dust will drift into the working area, avoiding affecting the working environment.
