[0025] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] See also Figures 1-5 This utility model provides a drying equipment for the production of water-soluble fertilizers containing macronutrients. The equipment includes a fertilizer processing box 1. The entire drying equipment can be fixed on the ground by existing support components. The water-soluble fertilizer containing macronutrients is hereinafter referred to as fertilizer. The bottom of the fertilizer processing box 1 is provided with a discharge port 2, and the top of the fertilizer processing box 1 is provided with a feeding hopper 3.

[0027] The feeding hopper 3 can be filled with undried fertilizer so that the fertilizer processing box 1 can process the fertilizer before drying. The discharge port 2 can be used to discharge the processed fertilizer.

[0028] In this embodiment: a material equalization component 4 is provided in the feeding hopper 3. An arc groove is opened in the feeding hopper 3. The material equalization component 4 includes a material distribution cylinder 41. The material distribution cylinder 41 is rotatably connected in the arc groove. Multiple material distribution grooves 42 are opened on the outer surface of the material distribution cylinder 41. The guide plate 5 is fixedly connected to the inner wall of the fertilizer processing box 1.

[0029] After the feed hopper 3 is filled with fertilizer, the arc groove can reduce the gap between the feed cylinder 41 and the feed hopper 3, so that the fertilizer can effectively enter the feed trough 42 on the surface of the feed cylinder 41. In this way, when the feed cylinder 41 rotates, multiple feed troughs 42 can be filled with fertilizer in sequence and quantitatively fed into the fertilizer processing box 1.

[0030] In this embodiment: a guide plate 5 is provided inside the fertilizer processing box 1. The guide plate 5 is fixedly connected to the inner wall of the fertilizer processing box 1 and is located below the feeding hopper 3.

[0031] The guide plate 5 is inclined, which can change the direction of fertilizer falling into the distribution trough 42.

[0032] In this embodiment: an active crushing component 7 is provided inside the fertilizer processing box 1. The active crushing component 7 includes a rotating rod 71, which is rotatably connected to the inner wall of the fertilizer processing box 1. Multiple crushing plates 72 are fixedly connected to the rotating rod 71, and the crushing plates 72 are located on one side of the guide plate 5.

[0033] When the fertilizer on the guide plate 5 rolls down freely, the rotating rod 71 rotates at high speed, which can drive multiple crushing plates 72 to rotate. The crushing plates 72 can strike the falling fertilizer, which can prevent the fertilizer from clumping in some areas.

[0034] In this embodiment: a servo motor 10 is fixedly connected to the outside of the fertilizer processing box 1. The output shaft of the servo motor 10 passes through the fertilizer processing box 1 and is fixedly connected to one end of the distributing cylinder 41. A belt drive mechanism 11 is connected between the distributing cylinder 41 and the rotating rod 71.

[0035] The belt drive mechanism 11 consists of a pair of pulleys of different sizes and a belt connected to the pair of pulleys. Since the rotating rod 71 needs to rotate at high speed to provide effective impact force, the pulley at one end of the rotating rod 71 can be smaller than the pulley at one end of the distribution cylinder 41. By starting the servo motor 10, it can drive the distribution cylinder 41 to rotate. The rotation of the distribution cylinder 41 can drive the rotating rod 71 to rotate through the belt drive mechanism 11. The rotation of the rotating rod 71 can drive the crushing plate 72 to crush the clumped fertilizer.

[0036] In this embodiment: A passive crushing component 6 is provided inside the fertilizer processing box 1. The passive crushing component 6 includes an impact plate 61, which is fixedly connected to the inner wall of the fertilizer processing box 1. Multiple protrusions 62 are fixedly connected to the surface of the impact plate 61, and the impact plate 61 is located below the side of the crushing plate 72.

[0037] The impact plate 61 is inclined, and the protrusion 62 is semi-circular. When the crushing plate 72 strikes the fertilizer and throws it out, the fertilizer can impact the impact plate 61. The protrusion 62 on the impact plate 61 provides point contact for the fertilizer, so that the fertilizer can be further crushed on the impact plate 61. This can meet the requirement of fertilizer particle uniformity so that the fertilizer can be dried evenly in the subsequent process.

[0038] In this embodiment: a heat insulation cylinder 8 is installed at the bottom of the fertilizer processing box 1, and the heat insulation cylinder 8 is connected to the discharge port 2. A heater 81 is installed on the inner wall of the heat insulation cylinder 8.

[0039] Fertilizer that rolls off the impact plate 61 can enter the insulation cylinder 8 through the discharge port 2. The insulation cylinder 8 can be mounted on the bottom of the fertilizer processing box 1 by a fixing frame. The inner wall of the insulation cylinder 8 can be lined with insulation cotton to provide insulation. The heater 81 is an electric heater, model DF20. The heater 81 can heat and dry the fertilizer inside the insulation cylinder 8.

[0040] In this embodiment: a conveying mechanism 9 is provided inside the insulation cylinder 8. The conveying mechanism 9 includes a feeding cylinder 91, which is fixedly connected to the inner wall of the insulation cylinder 8. One end of the feeding cylinder 91 is rotatably connected to a conveying cylinder 92. A spiral blade shaft 93 is provided between the feeding cylinder 91 and the conveying cylinder 92. A guide pipe 12 is fixedly connected to the feeding cylinder 91 and communicates with it. One end of the guide pipe 12 passes through the insulation cylinder 8 and is correspondingly connected to the discharge port 2.

[0041] The spiral blade shaft 93 is a spiral blade with a shaft. In this application, the feeding cylinder 91 is a single-opening cylinder structure and the conveying cylinder 92 is a double-opening cylinder structure. The opposite ends of the feeding cylinder 91 and the conveying cylinder 92 are respectively provided with mutually nested inner edges and outer edges, which are connected by bearings.

[0042] A support frame 13 is fixedly connected to the inner wall of the insulation cylinder 8. The conveying cylinder 92 is rotatably connected to the support frame 13. A support frame 2 14 is fixedly connected to the inner wall of the conveying cylinder 92. The spiral blade shaft 93 is rotatably connected to the support frame 2 14. A servo motor 2 15 is fixedly connected to one end of the insulation cylinder 8. The output shaft of the servo motor 2 15 passes through the insulation cylinder 8 and is fixedly connected to one end of the spiral blade shaft 93.

[0043] Support frame 13 provides rotational support for conveying cylinder 92, support frame 2 14 provides rotational support for spiral blade shaft 93, servo motor 2 15 drives spiral blade shaft 93 to rotate, and the rotation of spiral blade shaft 93 can push the fertilizer in feeding cylinder 91 and conveying cylinder 92 to move.

[0044] In this embodiment: an external toothed ring 19 is fixedly connected to the outer surface of the conveying cylinder 92, a gear 18 is meshed on the external toothed ring 19, a transmission rod 17 is fixedly connected to the gear 18, the transmission rod 17 is rotatably connected to the heat preservation cylinder 8, and a belt drive mechanism 16 is connected between the spiral blade shaft 93 and the transmission rod 17.

[0045] The belt drive mechanism 2 16 has the same structure as the belt drive mechanism 11. Since the belt drive mechanism 2 16 can drive the conveyor cylinder 92 and the spiral blade shaft 93 to rotate, the specific size of a pair of pulleys in the belt drive mechanism 2 16 can be set according to the speed requirements of the conveyor cylinder 92 and the spiral blade shaft 93.

[0046] In use, by starting the servo motor 15 and the heater 81, the fertilizer enters the feeding cylinder 91 through the discharge port 2 and the guide pipe 12 in sequence. The heater 81 can heat the outside of the feeding cylinder 91 and the conveying cylinder 92. The servo motor 15 can drive the spiral blade shaft 93 to rotate. At the same time, the spiral blade shaft 93 can drive the transmission rod 17 to rotate. The transmission rod 17 can drive the gear 18 to mesh with the external gear ring 19. The external gear ring 19 can drive the conveying cylinder 92 to rotate. The rotation of the conveying cylinder 92 can ensure the uniformity of heating with the heater 81. In this way, when the spiral blade shaft 93 conveys the fertilizer at the position of the feeding cylinder 91 toward the discharge end of the conveying cylinder 92, the conveyed fertilizer can be effectively dried by heat until it is discharged through one end of the conveying cylinder 92. In this application, a discharge port is provided at the bottom of one end of the heat preservation cylinder 8, which corresponds to the discharge end of the conveying cylinder 92. The discharge port can discharge the fertilizer discharged from the conveying cylinder 92.

[0047] All electrical components mentioned in this article are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail in this article.
