[0019] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0020] The seed selection device according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 3 As shown, the seed selection equipment of the embodiment of the present application may include a screening box 1, a feeding box 2, a feeding mechanism 3, a motor 4, a reduction mechanism 5, a vibration screening mechanism 6, a blower 7, a discharge barrel 8 and a conveyor 9.

[0022] Among them, a through hole is opened on one side of the screening box 1, and a ventilation mesh plate 10 is arranged at the through hole. A pipe support plate 11 is arranged inside the screening box 1, and the pipe support plate 11 is located below the vibrating screening mechanism 6. The feeding box 2 is arranged on the screening box 1 and is connected to the screening box 1.

[0023] It can be understood that by installing the ventilation mesh 10 in the through hole (not shown in the figure), the wind from the blower 7 can be discharged from the ventilation mesh 10, thereby preventing the wind blown by the blower 7 to the screening box 1 from forming vortices or other situations that affect the airflow.

[0024] It can be understood that, by providing the ventilation mesh 10, lighter impurities are retained in the screening box 1, thereby preventing the lighter impurities from scattering around, thereby ensuring the environmental protection effect of the seed selection process.

[0025] The feeding mechanism 3 is rotatably disposed in the feeding box 2 , and the feeding mechanism 3 may include a first sealing plate 30 , a second sealing plate 31 and a feeding shaft 32 .

[0026] The first sealing plate 30 and the second sealing plate 31 are arranged crosswise, and the first sealing plate 30 and the second sealing plate 31 are respectively arranged on the feeding rotating shaft 32, and are respectively arranged to perform rotation sealing on the bottom of the feeding box 2;

[0027] The feeding shaft 32 is rotatably disposed in the feeding box 2;

[0028] It should be noted that the bottom of the loading box 2 described in this example is square, so as to facilitate the rotational sealing of the bottom of the loading box 2 by the first sealing plate 30 and the second sealing plate 31, and through the cross-arrangement of the first sealing plate 30 and the second sealing plate 31, the material at the bottom of the loading box 2 can enter the intersection area of ​​the first sealing plate 30 and the second sealing plate 31, and through the rotation of the first sealing plate 30 and the second sealing plate 31, the material in the intersection area is rotated and discharged, thereby realizing quantitative and uniform discharge of materials (seeds) and preventing material accumulation.

[0029] The motor 4 is arranged on the screening box 1, the speed reduction mechanism 5 is rotatably arranged on the screening box 1, one end of the speed reduction mechanism 5 is connected to the output shaft of the motor 4, the other end of the speed reduction mechanism 5 is drivingly connected to the feeding shaft 32, the vibration screening mechanism 6 is connected to the output shaft of the motor 4, and one end of the vibration screening mechanism 6 is located below the feeding box 2;

[0030] It can be understood that, by connecting the motor 4 with the vibrating screening mechanism 6, the motor 4 can rotate to drive the vibrating screening mechanism 6 to do work, thereby vibrating and screening the material discharged from the feeding box 2. And by connecting the motor 4 with the reduction mechanism 5, the motor 4 rotates to drive the reduction mechanism 5 to rotate, so that the reduction mechanism 5 drives the feeding shaft 32 to rotate, and drives the first sealing plate 30 and the second sealing plate 31 to rotate, thereby achieving quantitative and uniform feeding of seeds. By setting the reduction mechanism 5, the use of driving components is reduced, thereby reducing the use cost of the device.

[0031] The blower 7 is arranged on one side of the screening box 1, and one end of the blowing pipe 70 arranged on the blower 7 extends to the pipe support plate 11, the lower barrel 8 is arranged on one side of the vibrating screening mechanism 6 and is located above the conveyor 9, and the first baffle plate 80 arranged on the lower barrel 8 is connected to the screening box 1 and covered above the conveyor 9. The conveyor 9 is arranged in the screening box 1, and one end of the conveyor 9 extends to the outside of the screening box 1.

[0032] It can be understood that, through the setting of the blower 7, the material screened and discharged from one side of the vibrating screening mechanism 6 can be screened for the second time, so that lighter impurities and bad seeds such as deflated seeds and hollow seeds can be screened for the second time, and these impurities and bad seeds can be blown toward the ventilation mesh plate 10, thereby achieving the screening of lighter impurities and bad seeds and improving the seed selection quality and efficiency of the device.

[0033] It can be understood that the discharge barrel 8 is arranged at an angle, and one end of the top of the discharge barrel 8 is located on one side of the air outlet pipe outlet, and is located below the end of the discharge near the vibrating discharge mechanism, so that the good seeds blown by the wind enter the discharge barrel 8 and are transported from the conveyor 9 to the next process. In this process, heavier impurities (such as stones) will not be blown by the wind and fall into the screening box 1.

[0034] It can be understood that, by providing the first baffle plate 80 , lighter impurities will not fall onto the conveyor 9 , thereby ensuring the performance of the conveyor 9 in conveying good seeds.

[0035] Specifically, during the actual operation, the relevant staff pours the unscreened seeds into the feeding box 2, and the controller (not shown in the figure) controls the motor 4 to rotate, the motor 4 drives the reduction mechanism 5 to rotate, the reduction mechanism 5 drives the feeding shaft 32 to rotate, and the feeding shaft 32 drives the first sealing plate 30 and the second sealing plate 31 to rotate, and the material in the intersection area of ​​the first sealing plate 30 and the second sealing plate 31 is fed to the vibrating screening mechanism 6.

[0036] When the motor 4 rotates, it can also drive the vibration screening mechanism 6 to rotate. The vibration screening mechanism 6 vibrates to vibrate and screen the material, and gradually vibrates the seeds to the discharge port of the vibration screening mechanism 6. During the vibration process, the controller controls the blower 7 to work, and the wind is transmitted from the blowing pipe 70 to the discharge port of the vibration screening mechanism 6, so that the fallen good seeds are blown into the discharge barrel 8, and are transported from the discharge barrel 8 to the conveyor 9. The conveyor 9 transports the good seeds to the next process, and blows the lighter impurities and bad seeds to the ventilation mesh plate 10, and is blocked and concentrated by the ventilation mesh plate 10. The heavier impurities fall directly to the bottom of the screening box 1, thereby completing the seed selection and improving the seed selection efficiency and quality.

[0037] In one embodiment of the present application, Figure 1-Figure 3 As shown, the speed reduction mechanism 5 may include a first gear 50 , a second gear 51 , a first transmission wheel 52 , a second transmission wheel 53 and a transmission belt 54 .

[0038] Among them, the first gear 50, the second gear 51 and the first transmission wheel 52 are respectively rotatably set on the screening box 1, the first gear 50 is connected to the output shaft of the motor 4, the first gear 50 is meshingly connected with the second gear 51, the first transmission wheel 52 is set on the second gear 51, the second transmission wheel 53 is rotatably set on the feeding box 2, the second transmission wheel 53 is connected to the feeding shaft 32, one end of the transmission belt 54 is sleeved with the second transmission wheel 53, and the other end of the transmission belt 54 is sleeved with the first transmission wheel 52.

[0039] It should be noted that the diameter of the first gear 50 described in this embodiment is smaller than the diameter of the second gear 51, and the diameter of the first transmission wheel 52 is smaller than the diameter of the second transmission wheel 53. Through the above-mentioned settings, the rotation speed of the output shaft of the motor 4 is reduced to make it suitable for the feeding speed of the feeding mechanism 3.

[0040] In one embodiment of the present application, Figure 1-Figure 3As shown, the vibrating screening mechanism 6 may include a vibrating plate 60 , a vibrating shaft 61 , a plurality of vibrating blocks 62 and a plurality of tension springs 63 .

[0041] Among them, the vibration plate 60 is slidably arranged in the screening box 1, a plurality of screening meshes are arranged on the vibration plate 60, a vibration shaft 61 is rotatably arranged in the screening box 1, the output shaft of the motor 4 is connected to the vibration shaft 61, a plurality of vibration blocks 62 are respectively arranged on the vibration shaft 61, and the plurality of vibration blocks 62 are respectively rotatably abutted against the vibration plate 60, one end of a plurality of tension springs 63 is respectively connected to the screening box 1, and the other ends of the plurality of tension springs 63 are respectively connected to the vibration plate 60.

[0042] It should be noted that the diameter of the screening mesh described in this embodiment is smaller than the diameter of the seeds, so that smaller impurities such as stones leak out from the screening mesh, so that only larger stone impurities are discharged from the discharge port of the vibration plate 60, so that the wind cannot blow the heavier impurities, thereby blowing the good seeds into the discharge barrel 8.

[0043] In one embodiment of the present application, Figure 1-Figure 3 As shown, a first collecting box 13 and a second collecting box 14 are arranged in the screening box 1 .

[0044] Among them, the first collecting box 13 is arranged in the screening box 1, and the first collecting box 13 is located below the vibration plate 60. The second collecting box 14 is arranged in the screening box 1 and is located on one side of the first collecting box 13, and the second collecting box 14 is located below the discharge port of the vibration plate 60.

[0045] It can be understood that, by setting up the first collecting box 13, smaller or lighter impurities fall into the first collecting box 13, and by setting up the second collecting box 14, larger or heavier impurities fall into the second collecting box 14, and by setting up the first collecting box 13 and the second collecting box 14 separately, the second collecting box 14 can continue to select seeds after the seed selection is completed, and continue to vibrate and screen the better seeds.

[0046] In one embodiment of the present application, Figure 1-Figure 3 As shown, a second material baffle plate 12 is provided in the screening box 1 , one end of the second material baffle plate 12 is located below one side of the material discharge port of the vibration plate 60 , and the other end of the second material baffle plate 12 extends to above the first collecting box 13 .

[0047] It can be understood that, by providing the second baffle plate 12 , all impurities leaking from the screening mesh can fall into the first collecting box 13 .

[0048] Specifically, in the actual operation process, the relevant staff pours the unscreened seeds into the feeding box 2, and the controller (not shown in the figure) controls the motor 4 to rotate, and the motor 4 drives the first gear 50 to rotate, and the first gear 50 drives the second gear 51 and the first transmission wheel 52 to rotate. The first transmission wheel 52 controls the second transmission wheel 53 to rotate through the transmission belt 54, and drives the feeding shaft 32 to rotate. The feeding shaft 32 drives the first sealing plate 30 and the second sealing plate 31 to rotate, and the material in the intersection area of ​​the first sealing plate 30 and the second sealing plate 31 is unloaded onto the vibration plate 60.

[0049] When the motor 4 rotates, it can also drive the vibration shaft 61 to rotate, and the vibration shaft 61 drives the vibration block 62 to rotate, so that the vibration block 62 intermittently vibrates and abuts against the vibration plate 60, and realizes the vibration of the vibration plate 60, so that the impurities on the vibration plate 60 are screened out from the screening mesh and fall into the first collecting box 13, and the vibration plate 60 vibrates to vibrate and screen the material, and gradually vibrates the seeds to the unloading port of the vibration plate 60. During the vibration process, the controller controls the blower 7 to work, and the wind force is transported from the blowing pipe 70 to the unloading port of the vibration screening mechanism 6, so that the fallen good seeds are blown into the unloading barrel 8, and are transported from the unloading barrel 8 to the conveyor 9. The conveyor 9 transports the good seeds to the next process, and blows the lighter impurities and bad seeds to the ventilation mesh plate 10, and is blocked and concentrated by the ventilation mesh plate 10, and the heavier impurities directly fall into the second collecting box 14, thereby completing the seed selection, improving the seed selection efficiency and seed selection quality.

[0050] In summary, the seed selection equipment of the embodiment of the present application can discharge materials evenly and can screen out impurities during the seed selection process, thereby improving the seed selection efficiency and quality.
