The rodless cavity at the fixed end of the first telescopic rod 61 is connected with a first connecting pipe, and a one-way valve is installed on the first connecting pipe. The flow direction in the first connecting pipe always flows to the fixed end of the first telescopic rod 61. The fixed end of the second telescopic rod 62 is fixedly mounted on the device housing 1, the rodless cavity of the fixed end of the second telescopic rod 62 is connected to 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, the rodless cavity of the fixed end of the second telescopic rod 62 is connected to a second connecting pipe, a pressure valve is installed on the second connecting pipe, and the flow direction in the second connecting pipe is always from the fixed end of the second telescopic rod 62. The baffle 63 is penetrated and slidably mounted on the device housing 1, the baffle 63 is fixedly connected to the movable end of the second telescopic rod 62, the baffle 63 installed on the first discharge port 11 can block the first discharge port 11, and the baffle 63 installed on the second discharge port 12 can block the second discharge port 12. The magnet 64 is fixedly mounted on the device housing 1, and the magnet 64 can adsorb the baffle 63.

[0044] In the initial state, the baffle 63 and the magnet 64 are in a mutually attracted state, 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, and the reciprocating motion 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 in a direction away from the fixed end of the first telescopic rod 61, the first telescopic rod 61 draws part of the 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 in a direction close to 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, and the air pressure in the fixed end of the second telescopic rod 62 increases, and the movable end of the second telescopic rod 62 applies a force to the baffle 63 in a direction away from the magnet 64. The air pressure in the fixed end of the second telescopic rod 62 gradually increases until the force applied by the movable end of the second telescopic rod 62 to the magnet 64 is greater than the magnetic force applied by the magnet 64 to the baffle 63. 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, and the popcorn-shaped water-soluble fertilizer is discharged through the first discharge port 11 and the second discharge port 12.

[0045] Afterwards, 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. The second connecting pipe opens, 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 is adsorbed by the magnet 64, and the first discharge port 11 and the second discharge port 12 are restored to a closed state, so as to avoid the popcorn-like water-soluble fertilizer production quality screening device from generating a large amount of dust during operation and being discharged through the first discharge port 11 and the second discharge port 12, thereby avoiding environmental pollution.

[0046] Reference Figure 1 , Figure 3 and Figure 4The device for screening the quality of popcorn-shaped water-soluble fertilizer after production also includes a dust reduction component 7, which includes a third telescopic rod 71, at least two nozzles 72 and blades 73. The fixed end of the third telescopic rod 71 is fixedly installed on the device housing 1, and the rodless cavity at the fixed end of the third telescopic rod 71 is filled with dust suppressant. The movable end of the third telescopic rod 71 is fixedly connected to the second screen plate 53, and the rodless cavity at the fixed end of the third telescopic rod 71 is connected to 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 to the fixed end of the third telescopic rod 71. At least two nozzles 72 are evenly and fixedly installed on the third discharge port 13, and the nozzles 72 are connected to the rodless cavity at the fixed end of the third telescopic rod 71, and a one-way valve is installed at the connection between the nozzles 72 and the third telescopic rod 71. The blade 73 is arranged in the device housing 1, and a transmission rod 74 is fixedly installed on the blade 73. The transmission rod 74 is passed through and rotatably installed on the device housing 1. The transmission rod 74 is coaxial with the third spur gear 43 and is fixedly connected. A ventilation hole 75 is opened on the device housing 1 above the blade 73.

[0047] The reciprocating motion of the second screen plate 53 drives 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 part of the 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 toward 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 toward the nozzle 72 and sprays it out through the nozzle 72, thereby achieving dust reduction at the third discharge port 13 to avoid environmental pollution.

[0048] The third spur gear 43 rotates to drive the transmission rod 74 to rotate, and the transmission rod 74 rotates to drive the blade 73 to rotate. The blade 73 rotates to blow the dust and impurities in the device shell 1 toward the third discharge port 13 and discharge them through the third discharge port 13, thereby avoiding excessive accumulation of dust and impurities in the device shell 1, which affects the normal use of the device for screening the quality of popcorn-like water-soluble fertilizer after production.

[0049] The implementation principle of the device for screening the quality of popcorn-like water-soluble fertilizer after production in an embodiment of the present application is as follows: when the device for screening the quality of popcorn-like water-soluble fertilizer after production is in operation, the popcorn-like 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 and then drives the screening component 5 to work, the screening component 5 works and screens the popcorn-like water-soluble fertilizer, and the popcorn-like water-soluble fertilizers of 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, thereby realizing the screening of popcorn-like water-soluble fertilizers of different particle sizes and improving the quality of the finished popcorn-like water-soluble fertilizers.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
