[0002] Water-retaining slow-release fertilizers refer to fertilizers that are chemically modified by water-absorbing polymers to chemically bond fertilizer nutrient groups to macromolecular skeletons, thereby making them have both water absorption, water retention and drought resistance properties, as well as slow-release properties. The main properties of water-retaining slow-release fertilizers are nutrient release rate and water absorption and water retention in the soil.

A feeding frame is fixedly installed on the surface of the granulator. A sorting device is provided on the surface of the granulator. The sorting device includes two positioning blocks. Both positioning blocks are fixedly connected to the surface of the granulator. The interiors of the two positioning blocks are slidably connected to limit rods. The ends of the two limit rods close to each other are fixedly connected to a sieve plate. The problem that the powder mixed in the fertilizer after granulation reduces the fertilizer processing efficiency of the granulator is solved.

[0004] However, the above patent still has the following problems in actual operation:

[0005] Traditional water-retaining slow-release fertilizers need to be dried during production. Under existing technologies, the drying process may take longer and require higher temperatures to achieve the ideal drying effect. It is difficult to ensure that the hot air is in full and effective contact with all the fertilizers, which may cause some fertilizers to be overheated while others are not completely dried, affecting the quality of the finished product.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to solve the technical problem that the traditional drying process of water-retaining slow-release fertilizers may take longer time and higher temperature to achieve the ideal drying effect, it is difficult to ensure that the hot air is in full and effective contact with all the fertilizers, which may cause some fertilizers to be overheated and some to be not completely dried, please refer to Figure 1-3 , this utility provides the following technical solutions:

[0022] A roasting device for producing water-retaining high-efficiency slow-release fertilizer comprises a main box body 1, a fertilizer inlet 2 is arranged on the top of the main box body 1, a fertilizer outlet 3 is opened at the bottom of the main box body 1, an electric control valve 4 is arranged on the fertilizer outlet 3, a supporting leg 5 is arranged on the bottom surface of the main box body 1, a first motor 6 is arranged on one side of the top of the main box body 1, a side platform 8 is arranged on the side of the main box body 1, and a second motor 7 is arranged on the top of the side platform 8.

[0023] In this embodiment, a roasting bin 10 and a lifting bin 11 are provided inside the main box 1. A spiral transmission shaft 12 is provided inside the lifting bin 11, and the spiral transmission shaft 12 is vertically arranged. One end of the rotating shaft in the spiral transmission shaft 12 is fixedly connected to the output shaft of the first motor 6. A discharge port 13 is provided at the top of the lifting bin 11 on the side close to the roasting bin 10, and a feed port 14 is provided at the bottom of the lifting bin 11 on the side close to the roasting bin 10. Both the discharge port 13 and the feed port 14 are connected to the roasting bin 10. The setting of the lifting bin 11 can lift the water-retaining slow-release fertilizer at the bottom of the roasting bin 10 to the top of the roasting bin 10 again, so that the water-retaining slow-release fertilizer can be repeatedly conveyed and dried, and the overall contact efficiency and frequency of all fertilizers with warm air can be improved, thereby effectively improving the drying effect and improving the quality of the finished water-retaining slow-release fertilizer.

[0024] In this embodiment, a fixed inclined plate 15 and a movable inclined plate 16 are provided inside the roasting bin 10. One end of the fixed inclined plate 15 at a higher point is fixedly connected to a side of the roasting bin 10 close to the lifting bin 11. The fixed inclined plate 15 and the movable inclined plate 16 are arranged in an inclined and staggered manner as a whole. A shaking assembly 18 is provided on the side of the roasting bin 10 away from the lifting bin 11. One end of the movable inclined plate 16 at a higher point is placed on the shaking assembly 18, and one end of the movable inclined plate 16 at a lower point is rotatably connected to the roasting bin 10 through an axle pin. An electric fan 17 is provided inside the roasting bin 10. The water-retaining slow-release fertilizer falls through the fixed inclined plate 15 and the movable inclined plate 16 in layers to ensure the height difference, so that the water-retaining slow-release fertilizer is in full contact with the hot air inside. At this time, the electric fan 17 performs blowing and drying, which can effectively increase the drying speed of the water-retaining slow-release fertilizer and improve production efficiency.

[0025] In this embodiment, the shaking assembly 18 includes an eccentric wheel 19, a pulley 20 and a rotating shaft 21. The eccentric wheel 19 is connected to the rotating shaft 21. The end of the rotating shaft 21 away from the eccentric wheel 19 is fixedly connected to the rotating shaft of the pulley 20. The eccentric wheel 19 is respectively arranged on the inner and outer sides of the roasting bin 10 of the pulley 20. Two groups of shaking components 18 are provided, one of which is set at a position matching the height of the second motor 7. The rotating shaft of the second motor 7 is fixedly connected to the rotating shaft of the pulley 20. The two groups of shaking components 18 are connected by the transmission belt 9 driving the pulley 20. The use of the second motor 7 and the transmission belt 9 enables the two groups of shaking components 18 to work synchronously, thereby improving the stability and reliability of the device. The shaking component 18 can intermittently lift the moving inclined plate 16 when the eccentric wheel 19 rotates through the structural design of the eccentric wheel 19, the pulley 20 and the rotating shaft 21, thereby driving the moving inclined plate 16 to shake. The water-retaining slow-release fertilizer that is clumped together can be shaken off by impact and collision, and the water-retaining slow-release fertilizer can be effectively prevented from staying and accumulating on the moving inclined plate 16, thereby ensuring that the overall falling roasting and drying path is smooth and the drying efficiency is ensured.

[0026] The working principle of the above content is as follows: the electric heating fan 17 is started to heat up the inside of the main box 1, the first motor 6 and the second motor 7 are started, and the water-retaining slow-release fertilizer to be roasted and dried is put into the inside of the main box 1 from the fertilizer inlet 2, and the water-retaining slow-release fertilizer slides downward layer by layer through the fixed inclined plate 15 and the movable inclined plate 16, and the second motor 7 drives the shaking component 18 to rotate, and the eccentric wheel 19 in the shaking component 18 intermittently pushes up the movable inclined plate 16 when rotating, so as to drive the movable inclined plate 16 to shake and shake the water-retaining slow-release fertilizer to prevent the water-retaining slow-release fertilizer from being scattered. The water-retaining slow-release fertilizer adheres or accumulates on the moving inclined plate 16. At this time, the electric fan 17 blows hot air on the continuously falling water-retaining slow-release fertilizer. When the water-retaining slow-release fertilizer falls to the bottom layer by layer, the water-retaining slow-release fertilizer is introduced into the interior of the lifting bin 11 through the inclined bottom surface. The first motor 6 drives the spiral transmission shaft 12 to rotate to lift the water-retaining slow-release fertilizer upward and throw it out from the discharge port 13 again, thereby performing reciprocating roasting and drying. The dried water-retaining slow-release fertilizer is discharged from the fertilizer outlet 3 by opening the electric control valve 4.
