Description

Technical Field

[0001] The utility model belongs to the technical field related to compound fertilizer production, in particular to a granulating device for coated controlled-release compound fertilizer. Background Art

[0002] Compound fertilizer refers to a fertilizer containing two or more nutrient elements of nitrogen, phosphorus and potassium. Compound fertilizer has the advantages of high nutrient content, few by-components and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization and promoting high and stable yields of crops. When compound fertilizer is processed, it is coated on the surface of compound fertilizer so that the compound fertilizer can be released more slowly. In the process of producing coated compound fertilizer, a granulating device is required for granulation to produce fertilizer, but it still has the following disadvantages in actual use:

[0003] 1. When the granulating device of the coated controlled-release compound fertilizer is working, the fertilizer is directly used for processing. During the processing, the fertilizer is directly transported and then cut by a cutter. During the cutting process, the fertilizer needs to be cut continuously. When working, different coordinated processing is required in the face of different feeding speeds, which is inconvenient;

[0004] 2. When the granulating device of the coated controlled-release compound fertilizer is working, the granulating is carried out directly after granulation. The fertilizer particles need to be transported before they can be dried. The transportation process is long, which can easily cause the fertilizer particles to stick together. After the fertilizer particles stick together, depressions occur during coating, etc., resulting in incomplete coating and affecting the uniformity of the fertilizer particle coating. Utility Model Content

[0005] The purpose of the utility model is to provide a granulating device for coated controlled-release compound fertilizers. By arranging a feeding cylinder, a feeding frame and an output frame, the utility model solves the problem that the granulating device for coated controlled-release compound fertilizers faces different feeding speeds when working, requires different coordinated treatments, is inconvenient to handle, and subsequent drying treatment easily causes the fertilizer particles to stick together.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a granulating device for coated controlled-release compound fertilizers, comprising a feed barrel, a feed frame and an output frame, wherein one end of the feed barrel is fixed with the feed frame, the top of the feed frame is inlaid with a protective net, one end of the feed barrel is fixed with a driving motor, the output end of the driving motor is fixedly connected with a driving shaft, a rotating cutter is fixed in an annular array on the peripheral side of the driving shaft away from one end of the feed barrel, and the bottom end of the feed frame is fixedly connected with the output frame. When working, the compound fertilizer material is conveyed through the feed barrel, the fertilizer is cut into particles by the rotating cutter driven by the driving motor, and conveyed through the feed frame, and the fertilizer conveyed in the feed frame is output to the equipment for the next step of processing through the output frame.

[0008] Furthermore, the drive shaft is movably connected through the conveying cylinder and extends out of the conveying cylinder. The rotating cutter is arranged outside the conveying cylinder. The drive shaft transmits the power generated by the driving motor to the spiral blades and the rotating cutter.

[0009] Furthermore, a feed port is fixedly connected to the upper circumference of the feed cylinder, and a spiral blade is fixed to the circumference of the drive shaft in the feed cylinder. The feed cylinder transports fertilizer materials into the feed port and transports the fertilizer materials by rotating the spiral blade.

[0010] Furthermore, a fixing hole is provided at one end of the output frame close to the feed barrel, and discharge holes are evenly provided on the outer side of the driving shaft of the feed barrel close to one end of the output frame. The discharge holes are arranged in the fixing hole, and the rotating cutter is arranged in the fixing hole. The output frame transports the fertilizer particles cut by the rotating cutter through the fixing hole.

[0011] Furthermore, a side of the output frame away from the material conveying cylinder is fixedly connected to an air inlet cylinder, the air inlet cylinder is arranged on the upper part of the output frame, and the output frame fixes the air inlet fan through the air inlet cylinder.

[0012] Furthermore, a fixing frame is fixed on the inner wall of the middle part of the air inlet tube, an air inlet fan is fixed in the fixing frame, the air inlet tube is connected to the air inlet fan through the fixing frame, and the air is transported to the output frame through the air inlet fan, so that the output frame is transported to the feeding frame.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem that the granulating device of the coated controlled-release compound fertilizer needs to perform different coordinated treatments and is inconvenient to handle when facing different feeding speeds when working by arranging a feeding barrel. When the driving shaft rotates, the spiral blades are driven to rotate. During the rotation of the spiral blades, the compound fertilizer material in the feeding barrel is transported to the end of the feeding barrel close to the feeding frame and extruded through the discharge hole. In the process that the driving motor drives the driving shaft to drive the spiral blades to rotate, the rotating cutter is driven to rotate synchronously. When the rotating cutter rotates, the compound fertilizer material extruded from the discharge hole on the feeding barrel is cut into particles and falls into the feeding frame. When working, the granulating device of the coated controlled-release compound fertilizer does not need to perform different coordinated treatments when facing different feeding speeds, and the handling is more convenient.

[0015] 2. The utility model solves the problem that the fertilizer particles are easily adhered to each other due to the subsequent drying process when the granulating device of the coated controlled-release compound fertilizer is working by arranging a feed cylinder, a feed frame and an output frame. The air inlet cylinder fixes the air inlet fan therein through a fixing frame. When the air inlet fan is working, air is sucked into the air inlet cylinder, and is transported to the output frame through the air inlet cylinder, transported to the feed frame through the output frame, and output through the protective net on the feed frame. In the process of air passing through the feed frame, the particles of the compound fertilizer passing through the feed frame are dried, so that the fertilizer particles output from the output frame are drier and there is less adhesion between the particles.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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. Specific embodiment 1

[0025] See also Figure 1-5 The utility model is a granulating device for coated controlled-release compound fertilizers, comprising a feeding barrel 1, a feeding frame 2 and an output frame 3. The feeding frame 2 is fixed at one end of the feeding barrel 1. When the feeding barrel 1 is working, it conveys the synthesized compound fertilizer material. A protective net 202 is inlaid and fixed on the top of the feeding frame 2. When the protective net 202 is working, the air entering the feeding frame 2 with moisture on the compound fertilizer is discharged, and the compound fertilizer after granulation is prevented from being blown out from the position of the protective net 202. A driving motor 102 is fixed at one end of the feeding barrel 1. The driving motor The output end of 102 is fixedly connected to a driving shaft 103, and a rotating cutter 105 is fixed in a ring array on the circumferential side of the driving shaft 103 away from one end of the feed barrel 1. The driving motor 102 drives the driving shaft 103 to rotate, drives the spiral blade 104 to rotate, and drives the rotating cutter 105 to rotate, cuts the compound fertilizer extruded in the feed barrel 1 into particles, and performs granulation operations. The bottom end of the feed frame 2 is fixedly connected to an output frame 3, and the bottom end of the output frame 3 is connected to a device for further processing the compound fertilizer particles, and the compound fertilizer particles are output through the output frame 3.

[0026] Specifically, the driving shaft 103 is movably connected through the conveying cylinder and extends out of the conveying cylinder 1. The rotating cutter 105 is arranged outside the conveying cylinder 1. When the driving shaft 103 rotates, the rotating cutter 105 is driven to rotate.

[0027] Furthermore, a feed port 101 is fixedly connected to the upper circumferential side of the feed barrel 1, and a spiral blade 104 is fixed to the circumferential side of the driving shaft 103 in the feed barrel 1. When the feed barrel 1 is working, the compound fertilizer material is transported into the feed barrel 1 through the feed port 101, and when the spiral blade 104 rotates, the compound fertilizer material is driven in the conveying barrel to the position of the discharge hole 106.

[0028] The operation process of this embodiment is as follows: during operation, after starting the driving motor 102, the produced compound fertilizer material is poured into the feed port 101, and is transported to the feed barrel 1 through the feed port 101. At this time, the driving motor 102 drives the driving shaft 103 to rotate. When the driving shaft 103 rotates, the spiral blade 104 is driven to rotate. During the rotation of the spiral blade 104, the compound fertilizer material in the feed barrel 1 is driven to the end of the feed barrel 1 close to the feed frame 2, and is extruded through the discharge hole 106. During the process of the driving motor 102 driving the driving shaft 103 to drive the spiral blade 104 to rotate, the rotating cutter 105 is synchronously driven to rotate. When the rotating cutter 105 rotates, the compound fertilizer material extruded from the discharge hole 106 on the feed barrel 1 is cut into particles and falls into the feed frame 2. Specific embodiment 2

[0030] See also Figure 1-5 On the basis of the specific embodiment 1, a fixing hole 201 is opened at one end of the output frame 3 close to the feeding barrel 1, and discharge holes 106 are evenly opened on the outer side of the driving shaft 103 of the feeding barrel 1 close to one end of the output frame 3. The discharge holes 106 are arranged in the fixing hole 201, and the rotating cutter 105 is arranged in the fixing hole 201. The output frame 3 is arranged in the position where the discharge hole 106 is opened at the end of the feeding barrel 1 through the fixing hole 201, so that the particles of the compound fertilizer cut by the rotating cutter 105 fall into the feeding frame 2.

[0031] Specifically, the side of the output frame 3 away from the feeding cylinder 1 is fixedly connected with an air inlet cylinder 301, and the air inlet cylinder 301 is arranged on the upper part of the output frame 3. When the output frame 3 is working, the air can be transported to the feeding cylinder 1 through the air inlet cylinder 301 through the air inlet fan 303.

The air inlet cylinder 301 fixes the air inlet fan 303 therein through the fixing frame 302. When the air inlet fan 303 is working, air is sucked into the air inlet cylinder 301, and is transported to the output frame 3 through the air inlet cylinder 301, and is transported to the feed frame 2 through the output frame 3, and is output through the protective net 202 on the feed frame 2. In the process of air passing through the feed frame 2, the particles of the compound fertilizer passing through the feed frame 2 are dried, so that the fertilizer particles output from the output frame 3 are drier and there is less adhesion between the particles.

[0033] The operation process of this embodiment is as follows: when working, the feed cylinder 1 conveys the particles cut by the rotating cutter 105 to the feed frame 2, conveys them to the output frame 3 through the feed frame 2, and conveys them to the next processing equipment through the output frame 3. During this conveying process, the air is sucked into the air inlet cylinder 301 by the air inlet fan 303 when working, and conveyed to the output frame 3 through the air inlet cylinder 301, conveyed to the feed frame 2 through the output frame 3, and output through the protective net 202 on the feed frame 2. In the process of air passing through the feed frame 2, the particles of the compound fertilizer passing through the feed frame 2 are dried, so that the fertilizer particles output from the output frame 3 are drier and there is less adhesion between the particles.
