[0048] The supporting plate 222 is perpendicular to the conveying direction of the second conveying belt 221. The supporting plate 222 can prevent the organic fertilizer conveyed by the first conveying machine from sliding off the second conveying belt. The number of supporting plates can be 6, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20, etc. It can be understood that the appropriate number of supporting plates can be installed according to the work requirement.

[0049] When the second transmission member 226 is a transmission belt, the second driving wheel 227 and the second driven wheel 224 are in the structure of a belt pulley.

[0050] When the second transmission member 226 is a transmission chain, the second driving wheel 227 and the second driven wheel 224 are in the structure of a chain wheel.

[0051] The working mode of the second conveying machine is as follows:

[0052] The second driving motor 229 drives the second driving shaft 228 to rotate, the second driving shaft 228 drives the second driving wheel 227 to rotate, the second driving wheel 227 drives the second driven wheel 224 to rotate through the second transmission member 226, the second driven wheel 224 drives the second rotating shaft 225 to rotate, the second rotating shaft 225 drives the second driving roller 223 to rotate, the second driving roller 223 drives the second driven roller 2211 to rotate through the second conveying belt 221, and the second conveying belt 221 drives the plurality of supporting plates 222 installed thereon to move.

[0053] The second conveying belt 221 receives the organic fertilizer conveyed by the first conveying machine, and the supporting plates 222 block the organic fertilizer from sliding off the second conveying belt 221. The second conveying belt 221 conveys the organic fertilizer to the drying box 23.

[0054] In order to facilitate the control of the first conveying machine, the second conveying machine, the heater and the like, a controller 7 is installed. The controller 7 is provided with a touch display screen, and the controller 7 is electrically connected with the first conveying machine 6, the second conveying machine 22 and the heater 29. The controller 7 is used for controlling the first conveying machine, the second conveying machine and the heater to work.

[0055] In order to facilitate the acquisition of the temperature of the preheating box, a first temperature sensor 20 is installed. The first temperature sensor 20 is installed on the preheating box 21 and is used for monitoring the air temperature in the preheating box 21. The first temperature sensor 20 is electrically connected with the controller 7. The air temperature monitored by the first temperature sensor 20 is displayed on the touch display screen.

[0056] In order to facilitate the acquisition of the temperature and humidity of each layer of the drying box, a humidity sensor 31 and a second temperature sensor 32 are installed. A plurality of humidity sensors 31 and second temperature sensors 32 are installed at intervals in the height direction of the drying box 23.

[0057] A plurality of guide plates 33 are installed at intervals and in a staggered manner from top to bottom on the drying box 23. Each guide plate 33 can serve as a drying guide layer, and a heater 29 is installed on each drying guide layer. Figure 1 、 4As shown in Figure 5, the lower end of the guide plate 33 forms a discharge port with a gap between it and the side of the drying box. The organic fertilizer conveyed on the guide plate falls into the next guide plate through the discharge port. It can be understood that the remaining end faces of the guide plate are connected to the drying box.

[0058] It should be noted that the multiple guide plates 33 are vertically staggered, which slows down the time it takes for the organic fertilizer to fall from the top to the bottom of the drying chamber, thus facilitating the drying of the organic fertilizer. The height difference between the guide plates helps to break up any clumps of organic fertilizer that have formed during drying when they fall and collide with the guide plate below, thereby preventing the formation of large clumps.

[0059] The number of guide plates installed can be 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, or 16. The number of guide plates installed can be selected according to the drying requirements.

This can rapidly heat the organic fertilizer, realize effective preheating, and improve the drying efficiency of the subsequent drying box.

[0069] Working mode:

[0070] The air blower 10 conveys air to the interlayer 81 of the hot air furnace 8 through the air guide pipe 9.

The unloading valve 5 is opened, the organic fertilizer in the storage tank 1 falls into the unloading pipe 4 through the unloading cone 102, falls into the first conveyor 6 below through the unloading valve 5, and the first conveying belt 68 of the first conveyor 6 conveys the organic fertilizer into the preheating box 21. The time for the first conveying belt to convey the organic fertilizer into the preheating box and out of the other end of the preheating box is set to 20-30 min. The organic fertilizer is heated sufficiently when passing through the preheating box, and part of the water contained in the organic fertilizer is removed. The first air extractor 17 extracts the gas in the preheating box 21 and conveys it to the first filter 18 for filtration.

[0097] The organic fertilizer out of the preheating box 21 is conveyed by the first conveying belt to the centralized unloading hopper 43, and the centralized unloading hopper 43 conveys the organic fertilizer to the second conveying belt 221 of the second conveyor 22. The plurality of supporting plates 222 on the second conveying belt 221 support the organic fertilizer and move it to the feeding port 2311 of the drying box along with the second conveying belt. The organic fertilizer falls into the drying box 23 through the feeding port 2311, i.e. falls onto the guide plate 33 on the top of the drying box 23, and the guide plate 33 guides the organic fertilizer obliquely. A plurality of guide plates 33 are installed obliquely and vertically in the drying box 23. Each guide plate 33 is correspondingly provided with a heater 29. The heater 29 can heat the corresponding guide plate, and the heater 29 heats the organic fertilizer guided on the guide plate 33, thereby realizing the heating and drying of the organic fertilizer. The plurality of guide plates 33 and the heaters 29 work together to effectively improve the drying efficiency of the organic fertilizer in the drying box.

[0098] The unloading plate 45 is also correspondingly provided with a heater 29, which can reheat and dry the organic fertilizer guided to the unloading plate. When the unloading plate guides the organic fertilizer to the unloading port, the organic fertilizer passes through the crushing mechanism, which crushes the organic fertilizer to remove the caked materials generated during the drying of the organic fertilizer. After being crushed by the crushing mechanism, the organic fertilizer is unloaded outwards through the unloading port, and the drying of the organic fertilizer is completed. The moisture content of the dried organic fertilizer is 10%-13%.
