DETAILED DESCRIPTION

[0021] 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.

[0022] The utility model provides Figure 1-5 The granulator for fertilizer processing shown in the figure comprises a machine housing 100 and a granulating mechanism 200 arranged above the machine housing 100. The granulating mechanism 200 comprises a bearing housing 201 arranged at the top of the machine housing 100 and connected to the inside of the machine housing 100. Two rotatable granulating die rollers 202 are arranged horizontally inside the bearing housing 201. The outer wall of one of the granulating die rollers 202 has a die particle protruding outward, and the outer wall of the other granulating die roller 202 has a die groove that can engage with the die particle. When the two granulating die rollers 202 rotate, the die particle engages with the die groove to achieve extrusion granulation of powdered fertilizer. The outer wall of the bearing housing 201 is fixed with a drive for driving the granulating die roller 202 to rotate. The driving motor 203 is provided, and the other ends of the two granulation die rollers 202 are provided with a transmission gear 204, and the outer walls of the two transmission gears 204 can be meshed. After the driving motor 203 is powered on and started, the granulation die roller 202 connected thereto is driven to rotate. The two granulation die rollers 202 are meshed at one end through the transmission gear 204 to realize reversing transmission, so that when a single granulation die roller 202 rotates, the other granulation die roller 202 can be driven to rotate in the same direction. The powdered fertilizer can be poured in between the two granulation die rollers 202 and extruded and granulated by using the molding position on the granulation die roller 202, so that the powdered fertilizer is processed into granular fertilizer and discharged from the bottom between the two granulation die rollers 202.

[0023] The side wall of the machine housing 100 is provided with a sorting mechanism connected to the granulating mechanism 200, and the sorting mechanism is used to separate the powdered fertilizer and the granulated fertilizer. The fertilizer processed by the granulating mechanism 200 is screened by the sorting mechanism so that the powdered fertilizer and the granulated fertilizer can be sorted out separately; in a preferred embodiment, the sorting mechanism includes a lower material cover 300 fixed to the side wall of the machine housing 100, and an inner ring cover 302 for filtering the powdered fertilizer is fixedly provided inside the lower material cover 300, and the bottom of the outer wall of the inner ring cover 302 is covered with filtering holes 304 for separating the granulated fertilizer and the powdered fertilizer, and the machine A feeding pipe 307 is fixedly provided inside the shell 100 of the device. One end of the feeding pipe 307 is connected to the inner top of the inner ring cover 302. The other end of the feeding pipe 307 is fixedly connected to a collecting bucket 308, and the collecting bucket 308 is located directly below the granulating mechanism 200. A collecting channel 303 for collecting powdered fertilizer is provided between the inner ring cover 302 and the lower material cover 300. A stirring component is provided inside the inner ring cover 302. The fertilizer dropped from the bottom of the granulating mechanism 200 enters the collecting bucket 308 and slides down the slope of the feeding pipe 307 into the inner ring cover 302. At the same time, the stirring component cooperates with the collecting bucket 308 to collect the powdered fertilizer. The fertilizer inside the inner ring cover 302 is stirred so that the powdered fertilizer can be discharged from the filter hole 304 into the lower material cover 300, while the extruded granular fertilizer is retained inside the inner ring cover 302 to achieve a screening effect; wherein, the stirring assembly includes a material transfer plate 305 which is arranged inside the inner ring cover 302 and can rotate around the axis of the inner ring cover 302, and a rotating drive device 310 for driving the material transfer plate 305 to rotate is fixedly provided on the outside of the machine housing 100, and two groups of stop needles 309 are symmetrically provided on one side of the material transfer plate 305 facing the inner wall of the inner ring cover 302, and each group of stop needles 309 is multiple and arranged in a The parallel spacing arrangement and the width between two adjacent stop needles 309 should be smaller than the size of the granular fertilizer, so that the granular fertilizer and the powdered fertilizer can be separated while stirring the fertilizer inside the inner ring cover 302, thereby achieving the function of shifting the granular fertilizer, thereby lifting the granular fertilizer to prepare for the discharge of the granular fertilizer, and at the same time driving the powdered fertilizer to be combed, which helps the powdered fertilizer to be discharged from the filter hole 304 of the inner ring cover 302 into the material collection channel 303. At the same time, with the arc shape of the material collection channel 303, the powdered fertilizer that falls into it can be gathered, which is convenient for the subsequent centralized discharge.

[0024] The bottom end of the discharge cover 300 is fixedly connected with a discharge nozzle 301 for discharging the powdered fertilizer in the material collection channel 303, and one side of the inner ring cover 302 is fixedly connected with a discharge channel 306. One end of the discharge channel 306 extends to the outside of the discharge cover 300 for discharging granular fertilizer. The setting of the discharge nozzle 301 enables the powdered fertilizer entering the material collection channel 303 to be discharged in a centralized manner, and the discharge channel 306 can assist in the discharge of the granular fertilizer lifted by the rotation of the material shifting plate 305. The granular fertilizer lifted by the rotation of the material shifting plate 305 moves to the port position of the discharge channel 306 and enters the discharge channel 306, and slides down along the slope of the discharge channel 306, so as to be discharged from the machine housing 100, thereby achieving the separate discharge of powdered fertilizer and granular fertilizer, which is convenient for subsequent collection.
