[0029] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a fertilizer cooling device includes: a cooling chamber 20, which is a rectangular box with a hollow interior.

The refrigeration unit 21 is electrically connected to the corresponding power supply. This is the prior art, so it will not be described in detail here.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, an anti-caking structure is installed inside the cooling chamber 20 to prevent fertilizer from caking during cooling. The anti-caking structure includes a motor 22, a driven shaft 31, and a return plate 37. The motor 22 is fixedly installed on one side wall of the cooling chamber 20. The driven shaft 31 is rotatably connected to one side wall of the cooling chamber 20. The return plate 37 is slidably connected inside the cooling chamber 20 and is located below the conveying pipe 24.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, the motor 22 can drive the auger 25 to rotate. One end of the shaft of the auger 25 can pass through the wall of the cooling chamber 20 and connect to the motor 22. A bevel gear is fixedly installed on the shaft part of the auger 25 that passes through the wall of the cooling chamber 20. The driven shaft 31 is cylindrical, and a bevel gear that can mesh with the bevel gear of the auger 25 is installed on the top of the driven shaft 31. The driven shaft 31 is vertical on the side wall of the cooling chamber 20. The return plate 37 consists of a vertical rectangular plate and the top of the vertical rectangular plate. The structure consists of inclined rectangular plates. The inclined rectangular plates of the return plate 37 are bent downwards, and the vertical rectangular plates of the return plate 37 can fit against one side wall of the cooling chamber 20. The anti-caking structure also includes a side box 30, a reciprocating groove 32, and a limiting groove 33. The side box 30 is fixedly connected to the side wall of the cooling chamber 20, and the bottom of the motor 22 is fixedly connected to the top of the side box 30. The side box 30 is a rectangular box with a hollow interior. The driven shaft 31 is rotatably connected inside the side box 30. The side box 30 moves towards... The sidewall facing the cooling chamber 20 is open. A reciprocating groove 32 is formed on the sidewall of the cooling chamber 20 corresponding to the driven shaft 31. A limiting groove 33 is symmetrically formed on the wall of the cooling chamber 20. The top and bottom of the reciprocating groove 32 can communicate with the symmetrical limiting groove 33. The anti-caking structure also includes a reciprocating plate 34, a limiting plate 35, and a driving block 36. The reciprocating plate 34 is fixedly connected to the vertical rectangular plate of the return plate 37. The reciprocating plate 34 is slidably connected within the reciprocating groove 32. The limiting plate 35... 5. Symmetrically fixedly connected to the upper and lower walls of the reciprocating plate 34, the driving block 36 is fixedly connected to the side wall of the reciprocating plate 34, the arc surface of the driven shaft 31 is fixedly connected to a half-curved rod at the same horizontal plane as the reciprocating groove 32, the curved rod only surrounds half of the arc surface of the driven shaft 31, the driving block 36 is a right-angled triangular block, the inclined surface of the driving block 36 can contact the curved surface of the curved rod, the limiting groove 33 can adapt to the sliding of the limiting plate 35, and the reciprocating groove 32 can adapt to the up and down sliding of the reciprocating plate 34;

[0033] In practical use, the fertilizer to be cooled is poured into the top of the feed pipe 23, and the power to the motor 22 is turned on. When the power to the motor 22 is turned on, it drives the auger 25 to rotate. When the auger 25 rotates, the bevel gear on its wall also rotates synchronously. When the bevel gear on the wall of the auger 25 rotates, it drives the bevel gear at the top of the driven shaft 31 to rotate. The driven shaft 31 is driven to rotate by the bevel gear at its top. When the driven shaft 31 rotates, it drives the curved rod on its wall to rotate. When the curved rod rotates, its arc surface will abut against the inclined surface of the drive block 36, and drive the drive block 36 upward. When the drive block 36 slides upward, it drives the reciprocating plate 34 to slide along the reciprocating groove 32. When the reciprocating plate 34 slides, it drives the limiting plate 35 to slide in the limiting groove 33. When the reciprocating plate 34 slides, it drives the return plate 37 to move upward in the cooling chamber 20. The curved rod on the wall of the driven shaft 31 and the drive block 36 are in contact. When the contact ends, the drive block 36 will move downward due to gravity. The drive block 36 can drive the reciprocating plate 34, the limiting plate 35 and the return plate 37 to move downward synchronously. Then, as the driven shaft 31 rotates, the curved rod on its wall will re-abut the drive block 36 and move upward, thus reciprocating. When the fertilizer enters the feed pipe 23, it will enter the conveying pipe 24 along the feed pipe 23 cavity. Then, as the auger 25 rotates, it will move towards the opening on the wall of the conveying pipe 24. As the auger 25 rotates, the fertilizer will be discharged from the opening on the wall of the conveying pipe 24. The refrigerator 21 can inject the generated cold air into the cavity of the cooling chamber 20. When the fertilizer is in the cooling chamber 20 cavity, it will be cooled by the cold air in the cooling chamber 20 cavity. Then it will fall onto the inclined rectangular plate of the reciprocating return plate 37, and finally fall onto the triangular block at the bottom of the cooling chamber 20 cavity and be discharged along the inclined surface of the triangular block towards the circular slot at the bottom of the cooling chamber 20.

[0034] In summary, by setting an anti-caking structure, fertilizer can be prevented from clumping in the cooling chamber 20. The anti-caking structure drives the return plate 37 to move up and down repeatedly when the auger 25 conveys fertilizer, thereby striking the fertilizer and preventing it from clumping. Therefore, compared with the prior art, this solution can effectively prevent fertilizer from clumping during cooling in the cooling chamber 20.

[0035] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, an efficiency-enhancing structure is provided inside the cavity of the conveying pipe 24. The efficiency-enhancing structure includes an auxiliary plate 26, a connecting shaft 27, a turntable 28, and an impact rod 29. The auxiliary plate 26 is fixedly connected inside the cavity of the conveying pipe 24. The connecting shaft 27 is fixedly connected to the end of the auger 25 located inside the cavity of the conveying pipe 24. The turntable 28 is fixedly connected to the end of the connecting shaft 27. The impact rod 29 is fixedly connected to the side wall of the turntable 28. The auxiliary plate 26 is a semi-circular plate with a gap between the bottom of the auxiliary plate 26 and the top of the auger 25. The lower contour of the auger 25 can fit against the bottom of the cavity of the conveying pipe 24. The connecting shaft 27 is cylindrical. The turntable 28 is disc-shaped. The diameter of the turntable 28 is the same as the diameter of the cavity of the conveying pipe 24. The impact rod 29 is a rod with a teardrop-shaped cross section. The length of the impact rod 29 is the same as the opening of the conveying pipe 24.

[0036] In practical use, when the auger 25 rotates, the auger 25 can drive the connecting shaft 27 to rotate in the cavity of the conveying pipe 24. When the connecting shaft 27 rotates, it can drive the turntable 28 and the striking rod 29 to rotate synchronously. When the auger 25 conveys fertilizer, the fertilizer will also come into contact with each auxiliary plate 26 in the cavity of the conveying pipe 24. When the auxiliary plate 26 comes into contact with the clumped fertilizer, the auxiliary plate 26 will break up the clumped fertilizer. When the striking rod 29 rotates, it will knock down the fertilizer that is blocking the opening of the conveying pipe 24.

[0037] In summary, by setting up an efficiency-enhancing structure, the auxiliary plate 26 can initially break up the clumps of fertilizer in the cavity of the conveying pipe 24, while the striking rod 29 can prevent blockage when the conveying pipe 24 opens to discharge material.

[0038] Working principle: The fertilizer to be cooled is poured into the feed pipe 23 from the top, and the power to the motor 22 is turned on. When the power to the motor 22 is turned on, it drives the auger 25 to rotate. When the auger 25 rotates, the bevel gear on its wall also rotates synchronously. When the bevel gear on the wall of the auger 25 rotates, it drives the bevel gear at the top of the driven shaft 31 to rotate. The driven shaft 31 is driven to rotate by the bevel gear at its top. When the driven shaft 31 rotates, it drives the curved rod on its wall to rotate. When the curved rod rotates, its arc surface will abut against the inclined surface of the drive block 36, and drive the drive block 36 upward. When the drive block 36 slides upward, it drives the reciprocating plate 34 to slide along the reciprocating groove 32. When the reciprocating plate 34 slides, it drives the limiting plate 35 to slide in the limiting groove 33. When the reciprocating plate 34 slides, it drives the return plate 37 to move upward in the cooling chamber 20. The curved rod on the wall of the driven shaft 31 contacts the drive block 36. At the end, the drive block 36 will move downwards due to gravity. The drive block 36 can drive the reciprocating plate 34, the limiting plate 35 and the return plate 37 to move downwards synchronously. Then, as the driven shaft 31 rotates, the curved rod on its wall will re-abut the drive block 36 and move upwards, thus reciprocating. When the fertilizer enters the feed pipe 23, it will enter the conveying pipe 24 along the cavity of the feed pipe 23. Then, as the auger 25 rotates, it will move towards the opening on the wall of the conveying pipe 24. As the auger 25 rotates, the fertilizer will be discharged from the opening on the wall of the conveying pipe 24. The refrigeration unit 21 can inject the generated cold air into the cavity of the cooling chamber 20. When the fertilizer is in the cavity of the cooling chamber 20, it will be cooled by the cold air in the cavity of the cooling chamber 20, and then fall onto the inclined rectangular plate of the reciprocating return plate 37. Finally, it will fall onto the triangular block at the bottom of the cavity of the cooling chamber 20 and be discharged along the inclined surface of the triangular block towards the circular slot at the bottom of the cooling chamber 20.
