[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An optimized screening device based on seed particle size, comprising:

The top of the slide table is provided with evenly distributed arc grooves, and the bottom of the arc grooves is provided with sieve holes;

[0010] Vibrator, the vibrator is installed at the bottom of the slide;

[0011] Top frame, top of the top frame is provided with evenly distributed top columns, the positions of the top columns are adapted to the sieve holes;

[0012] A guide rod is fixed to the bottom of the slide, a top frame is slidably connected to the outer wall of the guide rod, and the top frame and the slide are connected by a spring;

[0013] The driving assembly is used to drive the top frame to slide up and down along the guide rod, so that the top column can enter and exit the sieve hole to achieve the purpose of dredging.

[0014] Preferably: the driving assembly comprises:

[0015] A driving motor is installed on an outer wall of one side of the installation frame;

[0016] A ball head rod, one end of which is fixed to the output end of the driving motor, and a linkage arc plate is installed on one side of the top frame. The linkage arc plate is located on the rotation track of the ball head rod. Based on the operation of the driving motor, the linkage arc plate can be squeezed downward by the ball head rod, thereby causing the top column to detach from the sieve hole.

[0017] Preferably: a receiving platform is arranged at the lower side of the bottom end of the slide, the receiving platform is fixed on the supporting frame, two symmetrical blocking doors are hinged at the bottom of the receiving platform, and a control mechanism for controlling the opening and closing of the blocking doors is installed at the bottom of the two blocking doors.

[0018] Preferably: the control mechanism comprises:

[0019] Magnetic blocks: two sets of magnetic blocks are installed on the adjacent sides of the bottoms of the two blocking doors through mounting plates;

[0020] A support plate, the support plate is fixed to the bottom of the receiving platform;

[0021] An elastic telescopic rod assembly is installed between the support plate and the blocking door.

[0022] Preferably: the elastic telescopic rod assembly comprises:

[0023] A sleeve, one end of which is hinged to an outer wall of one side of the support plate;

[0024] A slide rod, one end of which is slidably connected to the inner wall of one end of the sleeve, and a slide ball is fixed to the other end of the slide rod;

[0025] A ball seat, which is fixed to the outer wall at the bottom of the blocking door, and a sliding ball is movably installed in the ball seat;

[0027] Preferably: a one-way exhaust valve is arranged at one end of the strip-shaped airbag, and an air inlet hole is arranged on the strip-shaped airbag, and the ventilation speed of the air inlet hole is much lower than that of the one-way exhaust valve.

[0028] Preferably: a receiving box is arranged below the receiving platform, a slide rail is fixed to the bottom of the support frame, and a roller matched with the slide rail is installed at the bottom of the receiving box.

[0029] The beneficial effects of the utility model are:

[0030] The utility model can place seeds from the upper end of the slide by arranging structures such as a slide, an arc-shaped groove and sieve holes, and screen the seeds based on the seeds sliding down. During the screening, the arc-shaped groove can better gather the seeds. By arranging structures such as a top frame and a top column, the drive component can be controlled to work regularly, thereby driving the top frame to slide up and down along the guide rod, so as to eject the seeds blocked in the sieve holes, thereby improving practicality.

[0031] The utility model is capable of adjusting the position of the ball head rod based on the operation of the driving motor by setting a driving component, thereby changing the position of the linkage arc plate.

[0032] The utility model provides a magnetic block, which can ensure that the two blocking doors are in a closed state based on the magnetic attraction of the magnetic block. When too many seeds are piled up in the receiving platform, the blocking doors are under too much pressure, thereby overcoming the magnetic attraction of the magnetic block, so that the two blocking doors are opened, during which the elastic telescopic rod assembly is compressed, and the seeds are discharged; the subsequent blocking doors can be reset based on the resilience of the elastic telescopic rod assembly.

[0033] The utility model provides an elastic telescopic rod assembly, so that when the blocking door is opened, the sliding rod can slide in the sleeve and the strip air bag is compressed. When the seeds are discharged, the sliding rod can slide reversely in the sleeve based on the rebound force of the strip air bag, thereby realizing structural resetting and improving reliability.

[0034] The utility model provides a one-way exhaust valve and an air inlet hole, so that when the strip air bag is compressed, exhaust can be discharged through the one-way exhaust valve. When resetting, the one-way exhaust valve is blocked, and air flow can only be replenished into the strip air bag from the air inlet hole, thereby extending the resetting time of the strip air bag, so that seeds have enough time to be completely discharged from the receiving platform, thereby improving reliability.

[0035] The utility model provides a receiving box, which can be used to receive fallen seeds; in addition, a receiving box of corresponding specifications can be placed under the slide to receive seeds with small particle sizes, etc., thereby improving practicality.

DETAILED DESCRIPTION

[0043] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0044] The embodiments of the present invention 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 having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Example

[0045] An optimized screening device based on seed particle size, such as Figure 1-6As shown, including:

[0046] A support frame 1, on which a mounting frame 3 is mounted;

[0047] The slide 2, the top surface of the slide 2 is sealed and movably connected to the inner wall of the mounting frame 3, the outer side of the bottom of the slide 2 is connected to the mounting frame 3 by a same annular elastic connecting belt 13, the top of the slide 2 is provided with evenly distributed arc grooves 17, and the bottom of the arc groove 17 is provided with a sieve hole 16;

[0048] A vibrator 20, the vibrator 20 is installed at the bottom of the slide 2;

[0049] A top frame 11, the top of which is provided with evenly distributed top columns 12, the positions of the top columns 12 being adapted to the sieve holes 16;

[0050] A guide rod 19, the guide rod 19 is fixed to the bottom of the slide 2, the top frame 11 is slidably connected to the outer wall of the guide rod 19, and the top frame 11 and the slide 2 are connected by a spring 18;

[0051] A driving assembly is used to drive the top frame 11 to slide up and down along the guide rod 19, so that the top column 12 can enter and exit the sieve hole 16 to achieve the purpose of dredging;

[0052] By setting structures such as the slide 2, the arc groove 17 and the sieve holes 16, seeds can be placed from the upper end of the slide 2, and the seeds can be screened based on the seeds sliding down. During this process, the arc groove 17 can better gather the seeds; by setting structures such as the top frame 11 and the top column 12, the drive component can be controlled to work regularly, thereby driving the top frame 11 to slide up and down along the guide rod 19, so as to facilitate the ejection of seeds blocked in the sieve holes 16, thereby improving practicality.

[0053] In order to facilitate the driving of the top frame 11 to rise and fall; Figure 3 , Figure 4 As shown, the driving component includes:

[0054] A driving motor 14, which is mounted on an outer wall of one side of the mounting frame 3;

[0055] A ball head rod 15, one end of which is fixed to the output end of the driving motor 14, and a linkage arc plate 9 is installed on one side of the top frame 11, and the linkage arc plate 9 is located on the rotation track of the ball head rod 15. Based on the operation of the driving motor 14, the linkage arc plate 9 can be squeezed downward by the ball head rod 15, so that the top column 12 is separated from the sieve hole 16;

[0056] By setting up a driving component, the position of the ball head rod 15 can be adjusted based on the operation of the driving motor 14, thereby changing the position of the linkage arc plate 9. When the driving motor 14 controls the ball head rod 15 to rotate periodically, the ball head rod 15 can periodically squeeze the linkage arc plate 9 downward, and when the ball head rod 15 is separated from the linkage arc plate 9, it is reset based on the rebound force of the spring 18. This is repeated, thereby achieving the purpose of driving the top frame 11 to slide up and down along the outer wall of the guide rod 19.

[0057] In order to facilitate batch cutting; Figure 1 , Figure 5 , Figure 6 As shown, a receiving platform 4 is provided at the lower side of the bottom end of the slide 2, and the receiving platform 4 is fixed on the support frame 1. Two symmetrical blocking doors 22 are hinged at the bottom of the receiving platform 4, and a control mechanism for controlling the opening and closing of the blocking doors 22 is installed at the bottom of the two blocking doors 22.

[0058] In order to facilitate the control of the opening and closing of the blocking door 22; Figure 6 As shown, the control mechanism includes:

[0059] Magnetic blocks 27, two groups of magnetic blocks 27 are installed on the adjacent sides of the bottoms of the two blocking doors 22 through the mounting plates 28;

[0060] A support plate 5, the support plate 5 is fixed to the bottom of the receiving platform 4;

[0061] An elastic telescopic rod assembly, which is installed between the support plate 5 and the blocking door 22;

[0062] By providing the magnetic block 27, the two blocking doors 22 can be kept in a closed state based on the magnetic attraction of the magnetic block 27. When too many seeds are accumulated in the receiving platform 4, the pressure on the blocking door 22 is too great, thereby overcoming the magnetic attraction of the magnetic block 27, so that the two blocking doors 22 are opened. During this period, the elastic telescopic rod assembly is compressed, and the seeds are discharged; subsequently, the blocking door 22 can be reset based on the resilience of the elastic telescopic rod assembly.

[0063] In order to facilitate structural restoration; Figure 6 As shown, the elastic telescopic rod assembly includes:

[0064] A sleeve 24, one end of which is hinged to an outer wall of one side of the support plate 5;

[0065] A slide rod 29, one end of which is slidably connected to the inner wall of one end of the sleeve 24, and a slide ball 23 is fixed to the other end of the slide rod 29;

[0066] A ball seat 21, the ball seat 21 is fixed to the bottom outer wall of the blocking door 22, and a sliding ball 23 is movably installed in the ball seat 21;

[0067] The strip airbag 10, the slide bar 29 and the sleeve 24 are all fixed with side brackets, and the two ends of the strip airbag 10 are respectively fixed to the side brackets of the slide bar 29 and the sleeve 24;

[0068] By setting up an elastic telescopic rod assembly, when the blocking door 22 is opened, the sliding rod 29 can slide in the sleeve 24, and the strip air bag 10 is compressed. When the seeds are discharged, based on the rebound force of the strip air bag 10, the sliding rod 29 slides reversely in the sleeve 24, thereby realizing structural resetting and improving reliability.

[0069] To improve reliability; Figure 6 As shown, a one-way exhaust valve 25 is provided at one end of the strip-shaped airbag 10, and an air inlet 26 is provided on the strip-shaped airbag 10, and the ventilation speed of the air inlet 26 is much lower than that of the one-way exhaust valve 25;

[0070] By providing a one-way exhaust valve 25 and an air inlet 26, when the strip air bag 10 is compressed, exhaust can be discharged through the one-way exhaust valve 25. When resetting, the one-way exhaust valve 25 is blocked, and air flow can only be replenished into the strip air bag 10 from the air inlet 26, thereby extending the resetting time of the strip air bag 10, so that the seeds have enough time to be completely discharged from the receiving platform 4, thereby improving reliability.
