The two opposite inner walls of the drying box 1 are respectively provided with a slide module 16. Multiple spreading components 6 are respectively arranged inside the corresponding drying basket 2, and the spreading components 6 are connected to the slide of the slide module 16.

[0035] It should be noted that the connection assembly 4 described in this embodiment can stably connect the drying basket 2 to the first support plate 11 or the telescopic assembly 8, and at the same time facilitate the easy disassembly of the drying basket 2, thereby facilitating the subsequent cleaning of the drying basket 2.

[0036] Furthermore, the spreading component 6 can turn over the accumulated fertilizer to prevent fertilizer accumulation from affecting the drying effect and efficiency.

[0037] Multiple auxiliary drying components 7 are arranged on the inner wall of the drying box 1, and the auxiliary drying components 7 are connected to the driving component 5. A third support plate 12 is arranged between the relatively arranged first support plate 11 and the telescopic component 8. A main pipe 13 is arranged on the third support plate 12, and the main pipe 13 is connected to the auxiliary drying components 7. Multiple drying pipes 14 are arranged between the two third support plates 12, and the drying pipes 14 are connected to the main pipe 13.

[0038] It should be noted that the drying tube 14 described in this embodiment is provided with a plurality of air outlets, and the air outlets are directly opposite to the bottom of the drying basket 2. When the driving component 5 is started, it can drive the auxiliary drying component 7 to start, thereby blowing hot air into the interior of the drying tube 14. The hot air is directly in full contact with the fertilizer at the bottom of the drying basket 2, thereby improving the drying effect of the fertilizer.

[0039] In one embodiment of the present invention, Figure 1 As shown, the driving assembly 5 may include a ball screw 50 and a plurality of sliders 51 , wherein the ball screw 50 is rotatably disposed inside the drying box 1 , and the plurality of sliders 51 are respectively connected to the ball screw 50 via threads.

[0040] It should be noted that the ball screw 50 described in this embodiment is connected to a driving motor, and the ball screw 50 can be driven to rotate by the motor.

[0041] Furthermore, the ball screw 50 is provided with a plurality of reciprocating threaded portions, and a plurality of sliders 51 are respectively arranged on the corresponding reciprocating threaded portions. When the ball screw 50 rotates, it can drive the sliders 51 to move back and forth up and down, and through the cooperation of the telescopic assembly 8, drive one end of the drying basket 2 to be higher than the other end, so that the fertilizer inside the drying basket 2 can move along the inclined drying basket 2, so that the fertilizer can be dispersed, thereby accelerating the efficiency of fertilizer drying.

[0042] In one embodiment of the present invention, Figure 1 As shown, the telescopic assembly 8 may include a second support plate 80 and a telescopic plate 81, wherein a second support shaft 18 is provided on the slider 51, one end of the telescopic plate 81 is rotatably connected to the second support shaft 18, and the other end of the telescopic plate 81 is slidably connected to the second support plate 80, and the second support plate 80 is connected to the drying basket 2.

[0043] In the embodiment of the present invention, the cooperation between the second support plate 80 and the telescopic plate 81 can drive the drying basket 2 to move left and right, which is beneficial to the rapid drying of the fertilizer.

[0044] In one embodiment of the present invention, Figure 4As shown, the auxiliary drying component 7 may include a cylinder body 70, a piston 71 and a piston rod 72, wherein the cylinder body 70 is installed on the inner wall of the drying box 1, and the cylinder body 70 is connected to the main pipe 13 through a conduit, the piston 71 is slidably arranged inside the cylinder body 70, one end of the piston rod 72 is connected to the piston 71, and the other end of the piston rod 72 is connected to the slider 51 through a fixing plate.

[0045] It should be noted that the cylinder 70 described in this embodiment is provided with a one-way valve, which allows external air to enter the interior of the cylinder 70, but does not allow the air inside the cylinder 70 to be discharged, so that the air can only be discharged from the conduit and enter the interior of the main pipe 13 and the drying pipe 14 through the conduit, so as to further blow and dry the fertilizer.

[0046] Furthermore, if Figure 6 and Figure 7 As shown, the connecting assembly 4 may include two connecting plates 40, a spring 41, two protrusions 42, two adjusting shafts 43, two extrusion blocks 44 and two first gears 45, wherein the upper surface of the first support plate 11 or the second support plate 80 is provided with a first groove 15, and the two opposite surfaces of the first groove 15 are respectively provided with second grooves 19, the two connecting plates 40 are relatively arranged on the lower surface of the drying basket 2, and the two connecting plates 40 are both arranged in the first groove 15, the spring 41 is arranged between the two connecting plates 40, the two protrusions 42 are respectively arranged on the opposite back surfaces of the two connecting plates 40, and the two protrusions 42 are respectively arranged in the corresponding second grooves 19, the two adjusting shafts 43 are respectively rotatably arranged in the corresponding second grooves 19, and one end of the adjusting shaft 43 extends to the outside of the first support plate 11 or the second support plate 80, the two extrusion blocks 44 are respectively arranged on the corresponding adjusting shafts 43, and the extrusion blocks 44 are arranged in contact with the protrusions 42, and the two first gears 45 are respectively arranged on the corresponding adjusting shafts 43, and the two first gears 45 are meshed and connected.

[0047] It should be noted that the connecting plate 40 described in this embodiment is made of elastic material. When the two connecting plates 40 are placed inside the first groove 15, the spring 41 is in a compressed state, the protrusion 42 is arranged near the bottom of the connecting plate 40, and the second groove 19 cooperates with the protrusion 42 to clamp the protrusion 42 inside the second groove 19.

[0048] Furthermore, the extrusion block 44 is a cam structure, and the adjusting shaft 43 is connected to the driving mechanism. The driving mechanism can drive the adjusting shaft 43 to rotate, and through the cooperation of the two first gears 45, the two extrusion blocks 44 are driven to rotate in opposite directions, so that the protrusion 42 can be squeezed to squeeze the protrusion 42 out of the second groove 19, and then the drying basket 2 is pulled upward to separate the connecting plate 40 from the first groove 15, thereby achieving the purpose of quickly disassembling the drying basket 2.

[0049] In one embodiment of the present invention, Figure 3 As shown, the spreading assembly 6 may include a tooth plate 60, a rotating shaft 61, a second gear 62 and a plurality of groups of spreading rods 63, wherein both ends of the rotating shaft 61 are rotatably connected to two slides respectively, the tooth plate 60 is arranged on the inner wall of the drying basket 2, the second gear 62 is arranged on the rotating shaft 61, and the second gear 62 is meshedly connected with the tooth plate 60, and the plurality of groups of spreading rods 63 are evenly distributed on the rotating shaft 61.

[0050] It should be noted that each group includes two vertically arranged spreading rods 63, and the two spreading rods 63 are staggered. The spreading rods 63 are U-shaped rods, and the spreading rods 63 are driven to rotate by driving the rotating shaft 61 to achieve the spreading of the fertilizer.

[0051] Furthermore, the moving direction of the slide module 16 is perpendicular to the tilting direction of the drying basket 2 so as to better spread the fertilizer.

[0052] In one embodiment of the present invention, Figure 1 As shown, a discharge pipe 17 is connected to the bottom of the drying basket 2, and the discharge pipe 17 extends to the outside of the drying box 1. A control valve is provided on the discharge pipe 17, and the fertilizer is discharged conveniently and quickly through the discharge pipe 17. The drying basket 2 can also be tilted by the driving component 5, thereby speeding up the discharge speed.

[0053] Specifically, the relevant personnel heat up the drying box 1 in advance to save the time of drying the fertilizer. Then the relevant personnel open the door of the drying box 1 and put the fertilizer into the drying basket 2. Then the slide module 16 is controlled to start. The slide module 16 drives the rotating shaft 61 and the second gear 62 to move. Due to the restriction of the tooth plate 60, the second gear 62 can rotate on its own, and drive the rotating shaft 61 and the spreading rod 63 to rotate on their own, so as to continuously spread the fertilizer, thereby improving the drying efficiency of the fertilizer.

[0054] At the same time, relevant personnel control the rotation of the ball screw 50, and the ball screw 50 drives the slider 51 to move up and down, and through the cooperation of the telescopic component 8, drives the drying basket 2 to tilt left and right, so that the fertilizer inside the drying basket 2 can move left and right, avoiding being fixed in one position, which is beneficial to improving the drying effect and efficiency of the fertilizer.

[0055] Furthermore, the slider 51 can also drive the piston rod 72 to move up and down. When the piston rod 72 moves downward, with the cooperation of the piston 71, the air inside the cylinder 70 is discharged, and the hot air is transmitted to the main pipe 13 and the drying pipe 14 through the conduit, and finally discharged from the air outlet. The air outlet is located at the bottom of the drying basket 2, so that the fertilizer in the drying basket 2 can be further dried, thereby improving the drying effect and efficiency of the fertilizer. When the piston rod 72 moves upward, the hot air enters the interior of the cylinder 70 from the one-way valve.

[0056] After the fertilizer is dried, the relevant personnel can open the control valve to discharge the fertilizer from the discharge pipe 17, and at the same time control the drying basket 2 to be lower on the left and higher on the right (that is, one end of the discharge pipe 17 is lower), so as to discharge the fertilizer conveniently and quickly.

[0057] In summary, the soil remediation fertilizer drying device of the embodiment of the present invention can achieve uniform spreading and dispersion of fertilizer, prevent fertilizer accumulation, ensure that the fertilizer and hot air are in full contact, thereby achieving uniform drying of the fertilizer, thereby improving the effect and efficiency of fertilizer drying, and avoiding the problem of nutrient loss caused by excessive drying.
