This drum granulator for fertilizer production uses a driving device to drive the driving gear to rotate. The rotation of the driving gear drives the horizontal cylinder to rotate. Through the rotation of the horizontal cylinder, the raw materials are rubbed and extruded to gradually form particles.

The installation of the driving gear is relatively convenient, and through the design of inserting the convex block into the installation groove, the driving gear is more stable when installed on the installation ring, thus ensuring that the rotation of the driving gear can stably drive the rotation of the horizontal cylinder.

[0022] Embodiment: As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the technical solutions in the embodiments of the present application effectively solve the technical problems that the existing drum granulator is inconvenient for the installation and disassembly of the driving gear, and the fixing of the driving gear is not stable enough, affecting the rotational stability of the horizontal cylinder. The general idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a drum granulator for fertilizer production, which includes a horizontal cylinder 1. A driving gear 2 is sleeved in the middle of the horizontal cylinder 1. Two driven pulleys 11 are fixedly installed on the horizontal cylinder 1. An installation ring 3 is fixedly installed in the middle of the horizontal cylinder 1. The driving gear 2 is sleeved on the installation ring 3. A fixing ring 5 is movably sleeved on the installation ring 3. Screws 52 are fixedly connected to the fixing ring 5 at equal circumferential intervals. Each screw 52 movably penetrates through the driving gear 2. A nut 53 is threadedly installed on each screw 52. The driving gear 2 is located between the two driven pulleys 11. The inner diameter of the driving gear 2 is larger than the inner diameters of the two driven pulleys 11. The fixing ring 5 is designed in a circular ring shape. Four abutting blocks 51 are fixedly installed on the inner wall of the fixing ring 5 at equal circumferential intervals. Four convex blocks 21 are fixedly installed on the inner wall of the driving gear 2 at equal circumferential intervals. Four installation grooves 31 are opened on the side surface of the installation ring 3 at equal circumferential intervals. Each convex block 21 is respectively inserted into the installation groove 31. Each abutting block 51 is respectively inserted into the installation groove 31 and is in close fit with the surface of each convex block 21. One end of the installation ring 3 is fixedly connected with a retaining ring 4. The driving gear 2 is located between the fixing ring 5 and the retaining ring 4. The fixing ring 5 and the retaining ring 4 are fixedly connected by the screws 52 and the nuts 53 in a threaded manner. The driving device is used to drive the driving gear 2 to rotate. The rotation of the driving gear 2 drives the horizontal cylinder 1 to rotate. The raw materials are frictionally and extruded through the rotation of the horizontal cylinder 1 to gradually form particles. When the driving gear 2 needs to be disassembled, the nut 53 is disassembled, and the fixing ring 5 and the retaining ring 4 can be separated. At this time, the limit fixation of the driving gear 2 is released, and the driving gear 2 can be disassembled from the horizontal cylinder 1, which is convenient for replacing the driving gear 2 to facilitate subsequent granulation. When installing the driving gear 2, the convex block 21 on the driving gear 2 is inserted into the installation groove 31 to realize the positioning installation of the driving gear 2. Then the abutting block 51 is inserted into the convex block 21, so that the screw 52 can smoothly penetrate through the driving gear 2 and the retaining ring 4. Tightening the nut 53 can complete the installation and fixation of the driving gear 2. The installation of the driving gear 2 is relatively convenient. And through the design that the convex block 21 is inserted into the installation groove 31, the driving gear 2 is more stable when installed on the installation ring 3, thus ensuring that the rotation of the driving gear 2 can stably drive the rotation of the horizontal cylinder 1.

[0024] Working principle:

[0025] First step, the driving device is used to drive the driving gear 2 to rotate. The rotation of the driving gear 2 drives the horizontal cylinder 1 to rotate. The raw materials are frictionally and extruded through the rotation of the horizontal cylinder 1 to gradually form particles. When the driving gear 2 needs to be disassembled, the nut 53 is disassembled, and the fixing ring 5 and the retaining ring 4 can be separated. At this time, the limit fixation of the driving gear 2 is released, and the driving gear 2 can be disassembled from the horizontal cylinder 1, which is convenient for replacing the driving gear 2 to facilitate subsequent granulation.

[0026] In the second step, when installing the driving gear 2, insert the bump 21 on the driving gear 2 into the installation groove 31 to achieve the positioning installation of the driving gear 2. Then insert the abutting block 51 into the bump 21, so that the screw rod 52 can smoothly penetrate through the driving gear 2 and the retaining ring 4, and tighten the nut 53 to complete the installation and fixation of the driving gear 2. The installation of the driving gear 2 is relatively convenient, and through the design of inserting the bump 21 into the installation groove 31, the driving gear 2 is more stable when installed on the installation ring 3, thereby ensuring that the rotation of the driving gear 2 can stably drive the horizontal cylinder 1 to rotate.
