[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-Figure 6 The wind screen specific gravity device with good cleaning effect shown in the figure comprises a chassis 1 with a wind screen cavity formed inside, a feeding hopper 2 is installed on the top of the chassis 1, and a material collecting box 4 is arranged on one side of the chassis 1, and a slag collecting box 8 is arranged on the other side; a wind screen specific gravity mechanism 3 is arranged in the wind screen cavity, a dust reduction component is arranged on the slag collecting box 8, and a filter plate 19 for filtering impurities is arranged in the slag collecting box 8, a slag discharge port 16 is arranged on one side of the slag collecting box 8, and a discharge port 22 is arranged at the bottom end of the material collecting box 4, and the filter plate 19 divides the interior of the slag collecting box 8 into a slag collecting cavity and a water storage cavity;

[0028] A cleaning component 9 for cleaning the filter plate 19 is also provided on the slag collecting box 8, and the cleaning component 9 includes a mounting block 93 movably arranged in the slag collecting box 8, and a cleaning member 94 is installed at the bottom of the mounting block 93. The cleaning member 94 can be a cleaning brush, and the specific design can be based on actual needs, which is not limited here, and the cleaning member 94 is driven by the movement of the mounting block 93 to move horizontally along the filter plate 19; the cleaning component 9 also includes an electric push rod 91 installed on the side wall of the slag collecting box 8, and the telescopic end of the electric push rod 91 extends into the slag collecting box 8 and is fixedly connected to one side of the mounting block 93.

[0029] Specifically, Figure 3 As shown, the wind screen specific gravity mechanism 3 includes a blower 20 installed at the bottom of the chassis 1, and a specific gravity screen 32 and an axle rod arranged in the chassis 1. Two springs 33 are fixed on both sides of the inner wall of the chassis 1, and the top ends of the four springs 33 are connected to the bottom of the specific gravity screen 32. A cam 34 is installed in the middle of the axle rod, and the convex end of the cam 34 can contact the bottom of the specific gravity screen 32. A motor 31 for driving the axle rod to rotate is installed on the side wall of the chassis 1, and an air inlet 21 is provided at the bottom end of the chassis 1. The blower 20 is located below the cam 34. Material through ports respectively connected to the material collecting box 4 and the slag collecting box 8 are opened on both sides of the chassis 1, and an exhaust port 12 is opened on one side of the chassis 1, and a filter cover 13 is installed in the exhaust port 12.

[0030] Specifically, Figure 1-Figure 3 as well as Figure 5 As shown, the dust reduction assembly includes a water filling valve 10 and a waste valve 15 connected to both sides of the bottom of the slag collecting box 8. A pump body 14 is also installed on one side of the slag collecting box 8, and the top of the pump body 14 is connected to a conveying pipe 17. An atomizing nozzle 18 is arranged at the top of the slag collecting box 8, and the atomizing nozzle 18 is connected to the conveying pipe 17.

[0031] When cleaning the seeds, the seeds can be added into the wind screen chamber in the chassis 1 through the feeding hopper 2, and then the air is blown through the hair dryer 20. At the same time, the shaft is driven to rotate by the motor 31, so that the shaft drives the cam 34 to rotate, and then the cam 34 continuously touches the specific gravity screen 32 through its convex end, so that the specific gravity screen 32 vibrates under the action of the spring 33. At this time, impurities with smaller specific gravity float above the specific gravity screen 32, and seeds with larger specific gravity are located on the specific gravity screen 32. Then, under the vibration of the specific gravity screen 32, the impurities roll down along the inclined direction of the specific gravity screen 32 into the slag collection box 8 and are discharged through the slag discharge port 16, while the seeds with larger specific gravity move upward along the inclined direction of the specific gravity screen 32 until they fall into the material collection box 4 and are discharged through the discharge port 22, thereby realizing efficient seed cleaning;

[0032] When impurities fall into the slag collecting box 8, water can be added to the inner bottom of the slag collecting box 8 through the water adding valve 10, and the water can be pumped out through the pump body 14, and then fed into the atomizing nozzle 18 through the conveying pipe 17, so that the atomizing nozzle 18 atomizes and sprays the water to reduce dust on the impurities falling into the slag collecting box 8, and then the impurities fall on the filter plate 19, and the impurities are cleared out through the slag discharge port 16, and the water falls to the inner bottom of the slag collecting box 8 through the filter plate 19, so as to achieve the purpose of recycling, and the water at the inner bottom of the slag collecting box 8 can be discharged through the waste discharge valve 15, so as to realize the waste discharge of the slag collecting box 8;

[0033] At the same time, when the filter plate 19 is blocked and the impurity filtering is affected, the electric push rod 91 can be used to drive the mounting block 93 to move, so that the mounting block 93 drives the cleaning member 94 to move horizontally along the top of the filter plate 19 to clean the top of the filter plate 19 until it is discharged from the slag discharge port 16, thereby cleaning the filter plate 19, thereby ensuring the filtering effect of the filter plate 19 and facilitating the discharge of impurities.

[0034] Furthermore, if Figure 5 As shown, a baffle 92 is also fixed to the inner wall of the slag collecting box 8 . The baffle 92 is arranged at an angle, and the baffle 92 is located above the mounting block 93 .

[0035] During the dust reduction process of impurities in the slag box 8, when impurities fall, they will fall on the baffle 92 and roll downward along the inclined direction of the baffle 92 to prevent the impurities from accumulating on the top of the mounting block 93, so as to facilitate the cleaning of the filter plate 19 by the cleaning member 94.

[0036] Furthermore, if Figure 3 and Figure 4 As shown, guide blocks 321 are installed on both sides of the specific gravity screen 32, and guide strips 322 are fixed at both ends of the specific gravity screen 32. The two guide strips 322 are respectively located in the two material through ports.

[0037] When impurities and seeds with a larger specific gravity roll on the specific gravity screen 32, the guide block 321 and the guide strip 322 can guide the impurities and seeds with a larger specific gravity, thereby facilitating the separate discharge of the impurities and seeds with a larger specific gravity.

[0038] Meanwhile, in this embodiment, if Figure 1-Figure 3 As shown, a first dust suction fan 5 is installed on one side of the collecting box 4, and a first dust bag 6 is connected to one side of the first dust suction fan 5. A dust exhaust port is also opened on the inner wall of the chassis 1, and a second dust suction fan 11 is fixed on one side of the chassis 1, and a second dust bag 7 is connected to one side of the second dust suction fan 11.

[0039] During the seed cleaning process, the second dust suction fan 11 sucks out the dust inside the chassis 1 through the dust exhaust port and discharges it into the second dust collecting bag 7 to achieve dust removal inside the chassis 1, and when the seeds fall into the receiving box 4, the first dust suction fan 5 sucks in the impurities with a smaller specific gravity remaining in the seeds and discharges them into the first dust collecting bag 6 to achieve re-cleaning of the seeds, thereby greatly improving the seed cleaning effect.

[0040] In addition, in one embodiment, if Figure 5 and Figure 6 As shown, a concave cavity is formed at the bottom of the mounting block 93 for mounting the cleaning member 94, and a locking screw 96 is threadedly connected to the mounting block 93. Two connecting blocks 95 are installed on one side of the cleaning member 94, and both connecting blocks 95 have threaded holes for threading the locking screws 96. A connecting groove connected to the concave cavity is also provided in the mounting block 93, and the connecting groove corresponds to the connecting block 95.

[0041] When the cleaning member 94 needs maintenance, the mounting block 93 can be driven to move by the electric push rod 91, so that the mounting block 93 drives the cleaning member 94 to move along the filter plate 19 until it is moved out of the slag discharge port 16. At this time, the locking screw 96 is unscrewed, and the cleaning member 94 is pulled to move the connecting block 95 out of the connecting groove, thereby realizing the disassembly between the cleaning member 94 and the mounting block 93, and then the cleaning member 94 is maintained or replaced. After maintenance or replacement, the cleaning member 94 is inserted into the bottom of the mounting block 93 through the connecting block 95 and the connecting groove, and then the locking screw 96 is screwed in to screw and fix the cleaning member 94 and the mounting block 93, completing the installation of the cleaning member 94, thereby realizing the rapid disassembly and assembly of the cleaning member 94, which is beneficial to the maintenance or replacement of the cleaning member 94, ensuring the filtering effect of the cleaning member 94 on the filter plate 19, and further facilitating the filtering of impurities.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
