[0088] Refer to Figure 3 , Figure 4 and Figure 5, the vibrating part 51 includes a rotating sleeve 511, a cross bar 512, a sliding sleeve 513, a first universal joint 514, a connecting rod 515, a second universal joint 516, a rotating rod 5171, a driving bevel gear 5172, a driven bevel gear 5173 and a screw rod 518. The rotating sleeve 511 is inserted and rotatably installed on the device housing 1, and the axis of the rotating sleeve 511 is parallel to but not coincident with the axis of the device housing 1.

[0089] When using the screening assembly 5, the transmission assembly 4 works and drives the rotating sleeve 511 to rotate. The rotation of the rotating sleeve 511 drives the cross bar 512 to rotate. The rotation of the cross bar 512 drives the sliding sleeve 513 to rotate around the axis of the rotating sleeve 511. While the sliding sleeve 513 rotates, it drives the connecting rod 515 to rotate. The rotation of the connecting rod 515 drives the first sieve plate 52 to slide up and down reciprocally inside the device housing 1. While the cross bar 512 rotates, it can evenly spread the popcorn-shaped water-soluble fertilizer conveyed from the discharge port of the screw conveyor 2 onto the first sieve plate 52. The up and down reciprocating movement of the first sieve plate 52 realizes the screening work of the popcorn-shaped water-soluble fertilizer. The popcorn-shaped water-soluble fertilizer screened by the first sieve plate 52 is spread on the second sieve plate 53, and the remaining popcorn-shaped water-soluble fertilizer is conveyed out through the first discharge port 11 for secondary processing.

[0090] While the first sieve plate 52 moves up and down reciprocally, it drives the second sieve plate 53 to move synchronously through the fixing rod 54.

[0091] Control the rotation of the rotating rod 5171. The rotation of the rotating rod 5171 drives the rotation of the driving bevel gear 5172. The rotation of the driving bevel gear 5172 drives the rotation of the driven bevel gear 5173. The rotation of the driven bevel gear 5173 drives the rotation of the screw rod 518. The rotation of the screw rod 518 drives the sliding sleeve 513 to slide on the cross bar 512. When it is necessary to increase the screening speed of the popcorn-shaped water-soluble fertilizer, control the rotation of the rotating rod 5171 to make the sliding sleeve 513 move away from the axis of the rotating sleeve 511, thereby increasing the amplitude of the reciprocating movement of the first sieve plate 52 and the second sieve plate 53 up and down, and improving the screening efficiency of the first sieve plate 52 and the second sieve plate 53.

[0092] Conversely, when it is necessary to improve the finished product quality of the popcorn-shaped water-soluble fertilizer during screening and avoid breakage caused by vibration during screening of the popcorn-shaped water-soluble fertilizer, control the rotation of the rotating rod 5171 to make the sliding sleeve 513 move closer to the axis of the rotating sleeve 511, thereby reducing the amplitude of the reciprocating movement of the first sieve plate 52 and the second sieve plate 53 up and down, avoiding breakage of the popcorn-shaped water-soluble fertilizer during screening, and improving the economy of the finished product of the popcorn-shaped water-soluble fertilizer.

The rotation of the second spur gear 42 drives the rotation of the third spur gear 43. The rotation of the third spur gear 43 drives the rotation of the fourth spur gear 44. The rotation of the fourth spur gear 44 drives the rotation of the rotating sleeve 511, realizing the driving work of the screening assembly 5 and improving the mechanical linkage of the screening device for the quality of popcorn-shaped water-soluble fertilizer after production.

[0095] Refer to Figure 4 and Figure 6, the screening device for the advantages and disadvantages of popcorn-shaped water-soluble fertilizer after production further includes two discharging components 6, which are respectively installed on the first discharging port 11 and the second discharging port 12. The two discharging components 6 both include a first telescopic rod 61, a second telescopic rod 62, a baffle 63 and a magnet 64. The fixed end of the first telescopic rod 61 is fixedly installed in the device housing 1. The movable end of the first telescopic rod 61 installed on the first discharging port 11 is fixedly connected to the first sieve plate 52, and the movable end of the first telescopic rod 61 installed on the second discharging port 12 is fixedly connected to the second sieve plate 53. A first communicating pipe is connected to the rodless cavity of the fixed end of the first telescopic rod 61, and a one-way valve is installed on the first communicating pipe. The flow direction in the first communicating pipe always flows towards the fixed end of the first telescopic rod 61. The fixed end of the second telescopic rod 62 is fixedly installed on the device housing 1. The rodless cavity of the fixed end of the second telescopic rod 62 is communicated with the rodless cavity of the fixed end of the first telescopic rod 61. A one-way valve is installed at the connection between the second telescopic rod 62 and the first telescopic rod 61. The flow direction at the connection between the second telescopic rod 62 and the first telescopic rod 61 is always from the first telescopic rod 61 to the second telescopic rod 62. A second communicating pipe is connected to the rodless cavity of the fixed end of the second telescopic rod 62, and a pressure valve is installed on the second communicating pipe. The flow direction in the second communicating pipe is always out of the fixed end of the second telescopic rod 62. The baffle 63 is inserted and slidably installed on the device housing 1, and the baffle 63 is fixedly connected to the movable end of the second telescopic rod 62. The baffle 63 installed on the first discharging port 11 can block the first discharging port 11, and the baffle 63 installed on the second discharging port 12 can block the second discharging port 12. The magnet 64 is fixedly installed on the device housing 1, and the magnet 64 can adsorb the baffle 63.

[0096] In the initial state, the baffle 63 and the magnet 64 are in a state of mutual adsorption, and the first discharge port 11 and the second discharge port 12 are in a closed state. When the first sieve plate 52 and the second sieve plate 53 screen the popcorn-shaped water-soluble fertilizer, the first sieve plate 52 and the second sieve plate 53 reciprocate in the device housing 1. The reciprocating movement of the first sieve plate 52 and the second sieve plate 53 drives the movable end of the first telescopic rod 61 to reciprocate. When the movable end of the first telescopic rod 61 moves away from the fixed end of the first telescopic rod 61, the first telescopic rod 61 pumps some air in the device housing 1 into the fixed end of the first telescopic rod 61 through the first connecting pipe. When the movable end of the first telescopic rod 61 moves towards the fixed end of the first telescopic rod 61, the first telescopic rod 61 pushes the air in the fixed end of the first telescopic rod 61 into the fixed end of the second telescopic rod 62. The air pressure in the fixed end of the second telescopic rod 62 increases, and the movable end of the second telescopic rod 62 exerts a force on the baffle 63 in the direction away from the magnet 64. The air pressure in the fixed end of the second telescopic rod 62 gradually increases until the force exerted by the movable end of the second telescopic rod 62 on the magnet 64 is greater than the magnetic force exerted by the magnet 64 on the baffle 63. Then, the movable end of the second telescopic rod 62 pushes the baffle 63 to move away from the magnet 64, and the first discharge port 11 and the second discharge port 12 are opened. The popcorn-shaped water-soluble fertilizer completes the discharging work through the first discharge port 11 and the second discharge port 12.

[0097] After that, the movable end of the first telescopic rod 61 continues to reciprocate with the first sieve plate 52 and the second sieve plate 53, and the air pressure in the fixed end of the second telescopic rod 62 continues to increase until the air pressure in the fixed end of the second telescopic rod 62 is greater than the preset pressure value of the pressure valve on the second connecting pipe. Then, the second connecting pipe is opened, and the gas in the fixed end of the second telescopic rod 62 is discharged to the outside through the second connecting pipe. The pressure in the fixed end of the second telescopic rod 62 decreases, the baffle 63 falls back and adsorbs to the magnet 64, and the first discharge port 11 and the second discharge port 12 return to the closed state, avoiding a large amount of dust generated during the operation of the popcorn-shaped water-soluble fertilizer production and quality screening device and being discharged through the first discharge port 11 and the second discharge port 12, thus avoiding environmental pollution.

[0098] Refer to Figure 1 、 Figure 3 and Figure 4, the screening device for the advantages and disadvantages of popcorn-shaped water-soluble fertilizer after production further includes a dust suppression component 7, and the dust suppression component 7 includes a third telescopic rod 71, not less than two nozzles 72 and blades 73. The fixed end of the third telescopic rod 71 is fixedly installed on the device housing 1. The rodless cavity of the fixed end of the third telescopic rod 71 is filled with a dust suppressant. The movable end of the third telescopic rod 71 is fixedly connected to the second sieve plate 53. The rodless cavity of the fixed end of the third telescopic rod 71 is communicated with a third connecting pipe, and a one-way valve is installed on the third connecting pipe. The flow direction in the third connecting pipe always flows towards the fixed end of the third telescopic rod 71. Not less than two nozzles 72 are evenly and fixedly installed on the third discharge port 13. The nozzle 72 is communicated with the rodless cavity of the fixed end of the third telescopic rod 71, and a one-way valve is installed at the connection between the nozzle 72 and the third telescopic rod 71. The blade 73 is arranged inside the device housing 1. A transmission rod 74 is fixedly installed on the blade 73. The transmission rod 74 passes through and is rotatably installed on the device housing 1. The transmission rod 74 is coaxially and fixedly connected to the third straight gear 43. A ventilation hole 75 is opened on the device housing 1 above the blade 73.

[0099] The second sieve plate 53 reciprocates, thereby driving the movable end of the third telescopic rod 71 to reciprocate. When the movable end of the third telescopic rod 71 moves away from the fixed end of the third telescopic rod 71, the third telescopic rod 71 draws in some external air into the fixed end of the third telescopic rod 71 through the third connecting pipe. When the movable end of the third telescopic rod 71 moves towards the fixed end of the third telescopic rod 71, the third telescopic rod 71 pushes the dust suppressant in the fixed end of the third telescopic rod 71 towards the nozzle 72 and sprays it through the nozzle 72, realizing the dust suppression work at the third discharge port 13 and avoiding environmental pollution.

[0100] The third straight gear 43 rotates, thereby driving the transmission rod 74 to rotate. The transmission rod 74 rotates, thereby driving the blade 73 to rotate. The blade 73 rotates, thereby blowing the dust and impurities in the device housing 1 towards the direction close to the third discharge port 13 and discharging them through the third discharge port 13, avoiding excessive accumulation of dust and impurities in the device housing 1 and affecting the normal use of a screening device for the advantages and disadvantages of popcorn-shaped water-soluble fertilizer after production.

[0101] The implementation principle of a screening device for the advantages and disadvantages of popcorn-shaped water-soluble fertilizer in an embodiment of the present application is as follows: When a screening device for the advantages and disadvantages of popcorn-shaped water-soluble fertilizer after production works, the popcorn-shaped water-soluble fertilizer enters the device housing 1 through the screw conveyor 2. The motor 3 works and drives the transmission component 4 to work. The transmission component 4 works, thereby driving the screening component 5 to work. The screening component 5 works and screens the popcorn-shaped water-soluble fertilizer. The popcorn-shaped water-soluble fertilizers with different particle sizes are discharged from the device housing 1 through the first discharge port 11, the second discharge port 12, and the third discharge port 13 respectively, realizing the screening work of popcorn-shaped water-soluble fertilizers with different particle sizes and improving the quality of the popcorn-shaped water-soluble fertilizer finished product.

[0102] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
