It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0020] See also Figures 1 to 4 An embodiment of the present invention provides a wheat cleaning and screening device, which includes a cleaning tank 1, a metal mesh filter cartridge 2, an adjusting component 3 and a stirring component 4.

[0021] In the embodiments of the present invention, please refer to Figure 1 、 Figure 2 and Figure 3 The cleaning tank 1 is provided with a metal mesh filter cartridge 2 that can slide out of the cleaning tank 1, and the upper cylinder surface of the metal mesh filter cartridge 2 is provided with an opening. The cleaning tank 1 is equipped with an adjustment component 3 for lifting the metal mesh filter cartridge 2 and sliding it up along the cleaning tank 1, and the adjustment component 3 includes a vertical rod 31 and a threaded rod 32. A plurality of vertically arranged vertical rods 31 are fixedly installed on the brackets 11 fixedly connected on both sides of the cleaning tank 1, and a sliding connection seat 33 is mounted on the vertical rod 31 located on one of the brackets 11. The connection seat 33 is fixedly connected to the upper edge ring 21 fixedly sleeved on the opening of the metal mesh filter cartridge 2, and any one of the brackets 11 is equipped with a rotatably connected threaded rod 32 and a servo motor embedded in it for driving the threaded rod 32 to rotate, and the threaded rod 32 passes through the threaded through hole opened in the corresponding connection seat 33 and is threadedly connected to the threaded through hole;

[0022] A drainage hopper 5 is installed on the tank wall on one side near the top of the cleaning tank 1, and a valve 6 is installed on the drainage hopper 5. An air pump 7 is fixedly installed on the outer tank wall on the other side near the top of the cleaning tank 1, and a nozzle 8 is fixedly installed on the output end of the air pump 7, and the spray end of the nozzle 8 is facing the drainage hopper 5.

[0023] It should be noted that: the servo motor is turned on to drive the threaded rod 32 to rotate, thereby driving the metal mesh filter cartridge 2 to descend and slide into the cleaning tank 1 or driving the metal mesh filter cartridge 2 to rise and slide out of the cleaning tank 1. When the wheat is initially cleaned and screened, the adjustment component 3 is used to drive the metal mesh filter cartridge 2 to slide into the cleaning tank 1 and make the upper ring 21 lower than the drainage bucket 5, keeping the water higher than the drainage bucket 5. At this time, the wheat is poured into the metal mesh filter cartridge 2, and the shriveled wheat or husks float on the water. The valve 6 and the air pump 7 are opened, so that the air pump 7 blows the wheat or husks floating on the water to the drainage bucket 5 through the nozzle 8, so that the wheat or husks floating on the cleaning water surface are discharged from the drainage bucket 5. After completion, the valve 6 and the air pump 7 are closed, and the stirring component 4 on the metal mesh filter cartridge 2 is used to stir the wheat in the metal mesh filter cartridge 2, so that the wheat is fully washed, and the sand and gravel mixed in the wheat can be filtered through the metal mesh filter cartridge 2. The stirring of the stirring component 4 accelerates the screening of wheat and debris.

[0024] After the wheat is washed and screened, the regulating assembly 3 is used to drive the metal mesh filter cartridge 2 to rise and slide out of the cleaning tank 1, so that the metal mesh filter cartridge 2 can quickly drain the wheat.

[0025] Furthermore, an annular edge groove that matches the upper edge ring 21 is opened on the top of the cleaning tank 1, so that after the metal mesh filter cartridge 2 slides into the cleaning tank 1 through the adjustment component 3, the upper edge ring 21 and the annular edge groove opened in the cleaning tank 1 are engaged with each other, thereby limiting the depth of the metal mesh filter cartridge 2 descending along the cleaning tank 1.

[0026] In addition, a drain valve is installed at the bottom of the cleaning tank 1 to discharge the water and dirt used to clean the wheat in the cleaning tank 1.

[0027] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 A stirring assembly 4 for stirring wheat is installed on the metal mesh filter cartridge 2, and the stirring assembly 4 includes a rotating motor 41, which is fixedly mounted on the upper edge ring 21 through a frame, and a rotating rod 42 is fixedly mounted on the output end of the rotating motor 41, and the rotating rod 42 extends into the metal mesh filter cartridge 2 and is coaxially arranged with the metal mesh filter cartridge 2, and a plurality of annularly distributed stirring blades 43 are fixedly mounted on the rotating rod 42.

[0028] It should be noted that: when the metal mesh filter cartridge 2 is immersed in the cleaning tank 1 for water washing, the rotating motor 41 is turned on to drive the stirring blades 43 on the rotating rod 42 to stir the wheat, so that the stirring blades 43 stir the wheat, so that the wheat is fully washed with water. After the wheat washing and screening is completed, the adjusting component 3 is used to drive the metal mesh filter cartridge 2 to rise and slide out of the cleaning tank 1, so that the metal mesh filter cartridge 2 drains the wheat. At this time, the rotating motor 41 is turned on to make the stirring blades 43 stir the wheat, thereby greatly accelerating the rate of wheat drainage.

[0029] In the embodiments of the present invention, please refer to Figure 2 and Figure 4 A top plate 9 is fixed on the top of the vertical rods 31 on the brackets 11 on both sides of the cleaning tank 1, and a heating tube 91 is fixedly installed on the inner wall of the top plate 9.

[0030] It should be noted that: after the wheat is washed and screened, the adjusting component 3 is used to drive the metal mesh filter cartridge 2 to rise and slide out of the cleaning tank 1, so that the metal mesh filter cartridge 2 can quickly drain the wheat. At this time, the heating tube 91 is turned on to cooperate with the stirring blade 43 to stir the wheat, further accelerating the rate of removing excess water from the wheat.

[0031] The working principle of the wheat cleaning and screening device provided by the utility model is as follows:

[0032] The servo motor is turned on to drive the threaded rod 32 to rotate, thereby driving the metal mesh filter cartridge 2 to slide down into the cleaning tank 1 or driving the metal mesh filter cartridge 2 to slide up and out of the cleaning tank 1. When the wheat is initially cleaned and screened, the adjustment component 3 is used to drive the metal mesh filter cartridge 2 to slide into the cleaning tank 1 and make the upper ring 21 lower than the drainage bucket 5, keeping the water higher than the drainage bucket 5. At this time, the wheat is poured into the metal mesh filter cartridge 2, and the shriveled wheat or husks float on the water. The valve 6 and the air pump 7 are opened, so that the air pump 7 blows the wheat or husks floating on the water through the nozzle 8. The drainage hopper 5 allows the wheat or husks floating on the cleaning water surface to be discharged from the drainage hopper 5. After completion, the valve 6 and the air pump 7 are closed, and the stirring component 4 on the metal mesh filter cartridge 2 is then used to stir the wheat in the metal mesh filter cartridge 2. Specifically, the rotating motor 41 is turned on to drive the stirring blades 43 on the rotating rod 42 to stir the wheat. The stirring blades 43 stir the wheat, so that the wheat is fully washed with water, and the sand and gravel mixed in the wheat can be filtered through the metal mesh filter cartridge 2. The stirring of the stirring component 4 accelerates the screening of the wheat and debris.

[0033] After the wheat is washed and screened, the regulating component 3 is used to drive the metal mesh filter cartridge 2 to rise and slide out of the cleaning tank 1, so that the metal mesh filter cartridge 2 drains the wheat. At this time, the heating tube 91 is turned on to cooperate with the stirring blade 43 to stir the wheat, further accelerating the rate of removing excess water from the wheat.
