[0013] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0014] like Figures 1 to 4 As shown, an embodiment of the present invention provides a fertilizer granule cooling device for cooling granulated and dried fertilizer granules, so that the temperature of the fertilizer granules quickly drops to a suitable range, which is convenient for subsequent further processing.

[0015] Please refer to Figure 1 , Figure 2 and Figure 3The fertilizer particle cooling device includes a frame 100, on which a cooling cylinder 200 is provided, and the cooling cylinder 200 includes an outer cylinder 201, an inner cylinder 202 arranged in the outer cylinder 201, and a lower cylinder 203 arranged at the bottom of the outer cylinder 201, and a receiving chamber 204 is formed between the outer cylinder 201 and the inner cylinder 202, and a feed port 205 communicating with the receiving chamber 204 is provided on the outer cylinder 201, and the fertilizer particles to be cooled can be poured into the receiving chamber 204 from the feed port 205, and an air inlet hole 206 is provided on the inner cylinder 202, and an air inlet air outlet is provided at one end of the inner cylinder 202. The fan 207 is used to blow air into the inner cylinder 202 so that the airflow passes through the air inlet hole 206, so that the airflow can contact the fertilizer particles in the accommodating chamber 204. The lower cylinder 203 is connected to the accommodating chamber 204, and a discharge port 208 is provided on the side wall of the lower cylinder 203. The frame 100 is also provided with a rotatable rotating seat 300 and a first driving assembly 400 connected to the rotating seat 300 in a transmission manner. The rotating seat 300 is located directly below the lower cylinder 203. The rotating seat 300 is provided with a lifting plate 500 that can be raised and lowered, and the lifting plate 500 is located above the lower cylinder 203. The lifting plate 500 is provided with a first exhaust hole 501 extending therethrough, and a stirring blade 502 is further provided on the lifting plate 500, and the stirring blade 502 extends into the accommodating chamber 204. The first driving assembly 400 drives the rotating seat 300 to rotate and drives the lifting plate 500 to rotate, so that the stirring blade 502 stirs the organic fertilizer particles in the accommodating chamber 204, ensuring that the organic fertilizer particles in the accommodating chamber 204 are evenly contacted with the airflow blown out of the air inlet 206; the frame 100 is also provided with a lifting seat 600 that can be raised and lowered and a lifting seat 600 that is transmission-connected to the lifting seat 600. The second driving component 700, the lifting seat 600 is rotatably connected with the lifting plate 500, and the second driving component 700 drives the lifting seat 600 to move, thereby driving the lifting plate 500 to rise to a position higher than the discharge port 208 or to fall to a position lower than the discharge port 208. When the lifting plate 500 is located at a position higher than the discharge port 208, the fertilizer particles poured into the accommodating chamber 204 are kept in the cooling cylinder 200 for cooling. When the lifting plate 500 is located at a position lower than the discharge port 208, the fertilizer particles in the accommodating chamber 204 are discharged from the cooling cylinder 200 through the discharge port 208.

[0016] Specifically, the operation steps of cooling the dried fertilizer particles using the fertilizer particle cooling device provided in this embodiment are as follows: first, operate the second driving assembly 700 to drive the lifting seat 600 to rise so that the lifting plate 500 is raised to a position higher than the discharge port 208, and then pour the fertilizer particles into the accommodating chamber 204 from the feed port 205, and the fertilizer particles are kept in the accommodating chamber 204 under the obstruction of the lifting plate 500, and then turn on the air intake fan 207 to blow air into the inner cylinder 202 through the air intake fan 207, and the air flow in the inner cylinder 202 passes through the air intake hole 206 into the accommodating chamber 204 and contacts with the fertilizer particles and is discharged from the first exhaust hole 501, so that the heat in the accommodating chamber 204 is taken away by the flowing air flow to accelerate the cooling of the fertilizer particles in the accommodating chamber 204, and the air intake fan 207 is turned on. The fan 207 simultaneously turns on the first driving assembly 400 to make the rotating seat 300 rotate under the drive of the first driving assembly 400, and the rotating seat 300 drives the lifting plate 500 to rotate so that the stirring blades 502 stir the fertilizer particles in the accommodating chamber 204, so that the fertilizer particles in the accommodating chamber 204 can all contact with the flowing airflow, ensuring that the fertilizer particles are evenly cooled, and avoiding the situation where some fertilizer particles in the accommodating chamber 204 are not cooled enough; after the fertilizer particles are cooled, the second driving assembly 700 is operated to drive the lifting seat 600 to descend so that the lifting plate 500 descends to a position lower than the discharge port 208. At this time, the fertilizer particles in the accommodating chamber 204 descend with the movement of the lifting plate 500 and are discharged from the discharge port 208, and the fertilizer particles that have been cooled in the cooling cylinder 200 can be taken out. The fertilizer particle cooling device provided in this embodiment improves the cooling efficiency of the fertilizer particles by accelerating the gas flow in the cooling cylinder 200 through the air intake fan 207, and ensures uniform cooling of the fertilizer particles in the cooling cylinder 200 by stirring the fertilizer particles through the stirring blades 502, thereby preventing the cooling speed of the fertilizer particles in some areas of the cooling cylinder 200 from being lower than that of other fertilizer particles, which affects subsequent processing. In addition, the fertilizer particle cooling device is simple to operate and easy to use.

[0017] like Figure 1 and Figure 2As shown, the first driving assembly 400 includes a driving motor 401, a first sprocket 402 disposed at the output end of the driving motor 401, a second sprocket 301 is sleeved on the rotating seat 300, and the first sprocket 402 and the second sprocket 301 are connected by a transmission chain 403. The driving motor 401 is used to drive the first sprocket 402 to rotate and transmit power to the second sprocket 301 through the transmission chain 403, so that the rotating seat 300 can be driven by the driving motor 401 to continuously rotate, and the stirring blade 502 continuously stirs the fertilizer particles in the accommodating chamber 204 during the rotation of the rotating seat 300, so as to ensure that the fertilizer particles in the container are cooled quickly and evenly.

[0018] like Figure 2 and Figure 4 As shown, the lifting plate 500 is provided with a plurality of stirring blades 502, and the stirring blades 502 are arranged at equal intervals along the circumference of the inner cylinder 202 on the lifting plate 500, and the stirring blades 502 are arranged at intervals from the inner cylinder 202. The stirring effect is improved by arranging a plurality of stirring blades 502 on the lifting plate 500, and the stirring blades 502 are arranged at equal intervals along the circumference of the inner cylinder 202 and keep a certain distance from the inner cylinder 202, so as to avoid the collision between the stirring blades 502 and the inner cylinder 202 during the rotation of the lifting plate 500, which is beneficial to improve the stability of the fertilizer particle cooling device, and at the same time, the first exhaust holes 501 are respectively arranged between any two adjacent stirring blades 502, so that the airflow in the accommodating cavity 204 can be stably discharged outside the accommodating cavity 204.

[0019] Please combine Figure 2 and Figure 3 , a vertical guide cylinder 302 is provided on the rotating seat 300, and a guide column 503 matched with the guide cylinder 302 is provided on the lifting plate 500. The guide cylinder 302 is used to cooperate with the guide column 503 and limit the direction in which the lifting plate 500 moves on the rotating seat 300, so as to prevent the lifting plate 500 from unexpectedly deflecting or tilting when moving, resulting in a gap between the lifting plate 500 and the lower cylinder 203, thereby improving the sealing of the accommodating cavity 204 and preventing the fertilizer particles from leaking from between the lifting plate 500 and the lower cylinder 203, and two guide cylinders 302 are provided on the rotating seat 300 at intervals, and two guide columns 503 are provided on the lifting plate 500 to match the guide cylinders 302 one by one, so as to prevent the lifting plate 500 from rotating relative to the rotating seat 300, which is conducive to improving the stability of the cooperation between the lifting plate 500 and the rotating seat 300.

[0020] Please refer to Figure 2 and Figure 3 The lifting seat 600 is provided with a vertical guide rod 601, the cross section of the guide rod 601 is polygonal, and the frame 100 is provided with a guide hole matched with the guide rod 601. The guide rod 601 is arranged on the lifting seat 600 to match with the guide hole on the frame 100, so as to ensure that the lifting seat 600 moves in the vertical direction on the frame 100 and drives the lifting plate 500 to move, and prevent the lifting seat 600 from deviating from the preset direction when moving, so that the fertilizer particle cooling device can operate smoothly.

[0021] In detail, the second driving assembly 700 includes an oil cylinder 701 and a piston rod 702 disposed at the output end of the oil cylinder 701, and one end of the piston rod 702 away from the oil cylinder 701 cooperates with one end of the guide rod 601. The oil cylinder 701 drives the piston rod 702 to extend or retract into the oil cylinder 701, and the lifting seat 600 can be driven to move on the frame 100 through the movement of the piston rod 702. When the piston rod 702 extends out of the oil cylinder 701, the piston rod 702 pushes the lifting seat 600 to rise. At this time, the lifting plate 500 is driven by the lifting seat 600 to rise to a position higher than the discharge port 208, so that the lifting plate 500 closes the accommodating chamber 204. And keep the fertilizer particles in the cooling cylinder 200. When the piston rod 702 retracts into the oil cylinder 701, the piston rod 702 drives the lifting seat 600 to descend. At this time, the lifting plate 500 is driven by the lifting seat 600 to descend to a position lower than the discharge port 208, so that the fertilizer particles in the accommodating chamber 204 can be discharged from the discharge port 208. That is, the position of the lifting plate 500 can be conveniently adjusted by controlling the movement of the piston rod 702 through the oil cylinder 701.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the outer cylinder 201 is further provided with a feed hopper 800, and the feed hopper 800 is communicated with the feed port 205. The feed hopper 800 provided on the outer cylinder 201 is used to guide the fertilizer particles to be poured into the feed port 205, so as to facilitate pouring the fertilizer particles to be cooled into the cooling cylinder 200, and prevent the fertilizer particles from falling outside the feed port 205 and causing losses when adding fertilizer particles to the cooling cylinder 200.

[0023] In this embodiment, a guide plate 210 is provided on the lower cylinder 203, and the guide plate 210 is located at the opening of the discharge port 208 and the height of the guide plate 210 gradually decreases in the direction away from the discharge port 208. After the fertilizer particles are discharged from the discharge port 208, the fertilizer particles fall on the guide plate 210 and move along the guide plate 210, so that the fertilizer particles are guided to a designated position by the guide plate 210, so that the fertilizer particles that have been cooled can be collected in one place for further processing.

[0024] like Figure 2 and Figure 3 As shown, the lower cylinder 203 is provided with a second exhaust hole 209, which penetrates the lower cylinder 203 and communicates with the internal space of the lower cylinder 203. The second exhaust hole 209 is provided on the lower cylinder 203 for the gas discharged from the accommodating chamber 204 to pass through. When the lifting plate 500 moves to a position higher than the discharge port 208, the gas in the accommodating chamber 204 passes through the first exhaust hole 501 into the lower cylinder 203 and then passes through the second exhaust hole 209 to be discharged to the external environment, which is beneficial to improving the exhaust efficiency of the fertilizer particle cooling device and preventing heat from being retained in the lower cylinder 203 and affecting the cooling of the fertilizer particles in the accommodating chamber 204.

[0025] Please refer to Figure 1 and Figure 3 The outer cylinder 201 has a jacket 211, and the jacket 211 is arranged around the accommodating chamber 204. The outer cylinder 201 is also provided with a liquid inlet pipe 212 and a liquid discharge pipe 213, and the liquid inlet pipe 212 and the liquid discharge pipe 213 are respectively communicated with the jacket 211. By arranging the jacket 211 on the outer cylinder 201, and arranging the liquid inlet pipe 212 and the liquid discharge pipe 213 communicated with the jacket 211, the cooling medium can circulate in the jacket 211, so that the temperature of the cooling cylinder 200 is maintained within a suitable range, preventing the cooling cylinder 200 from absorbing the heat of the fertilizer particles and causing an adverse effect on the cooling of the fertilizer particles, which is conducive to maintaining a good working efficiency of the fertilizer particle cooling device.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
