[0027] The following describes this in conjunction with the preferred embodiments of the device of the present utility model.

[0028] Please refer to Figure 1-6 As shown in the figure, the granulating device for producing rare earth ferrosilicon alloy includes a frame 1. A first crushing box 2 is fixedly installed at the top of the frame 1. A transfer hopper 3 is fixedly connected to the bottom of the first crushing box 2. By using gravity and the fluidity of the material, the preliminarily crushed material can smoothly slide into the second crushing box 4.

A discharge plate 9 is provided at the bottom of the discharge hopper 6. A feed box 5 is fixedly installed at the top end of the first crushing box 2. A feed port 501 is provided on one side of the top of the feed box 5. The feed port 501 extends into the interior of the feed box 5 and is provided with a guide plate 502. The feed box 5 serves as the inlet of the raw material. The feed port 501 allows the raw material to enter, and the guide plate 502 ensures that the raw material can smoothly and evenly enter the first crushing box 2, avoiding blockage and uneven crushing.

[0029] Among them, a first crushing mechanism 7 is provided inside the first crushing box 2. The first crushing mechanism 7 serves as the place for preliminary crushing. Through the action of the first crushing mechanism 7, the large rare earth ferrosilicon alloy raw material is crushed into smaller particles for further processing. And a second crushing mechanism 8 is provided inside the second crushing box 4. The second crushing mechanism 8 crushes the preliminarily crushed material into fine particles that meet the requirements. The first crushing box 2 is connected to the second crushing box 4 through the provided transfer hopper 3.

[0030] In another embodiment provided by the present utility model, as Figure 3 shown, the first crushing mechanism 7 includes a main rotating shaft 701.

And a cooperating slave rotating shaft 703 and a slave crushing gear 704 are provided beside the main rotating shaft 701. One end of the main rotating shaft 701 extends to the outside of the first crushing box 2 and is fixedly connected to a first motor 705 through a bearing mounting seat 706. The other ends of the main rotating shaft 701 and the slave rotating shaft 703 that penetrate to the outside of the first crushing box 2 are respectively connected to a first main gear 707 and a first slave gear 708. The first main gear 707 and the first slave gear 708 are meshed with each other.

[0031] Specifically, the rotation of the main rotating shaft 701 is driven by the first motor 705, thereby driving the rotation of the main crushing gear 702. Then, through the meshing cooperation of the first main gear 707 and the first driven gear 708, the rotation of the driven rotating shaft 703 and the driven crushing gear 704 is driven. The main crushing gear 702 and the driven crushing gear 704 use the shearing force and extrusion force generated by gear transmission and shaft rotation to initially crush large raw materials into smaller particles, thereby realizing the initial crushing of the raw materials.

[0032] In another embodiment provided by the present utility model, as Figure 3 、 5 shown in FIGS. 5 and 6, the second crushing mechanism 8 includes a first crushing roll 801 and a second crushing roll 802. The first crushing roll 801 and the second crushing roll 802 are oppositely arranged inside the second crushing box 4. At the front side central axes of the first crushing roll 801 and the second crushing roll 802, a first connecting rod 803 and a fourth connecting rod 806 are respectively movably connected. The first connecting rod 803 is movably connected to the fourth connecting rod 806 through the provided second connecting rod 804 and third connecting rod 805. One end of the first connecting rod 803 is movably connected to the output end of the telescopic rod 807, and the other end of the first connecting rod 803 is movably sleeved outside the first movable rod 810 provided below the first crushing roll 801. The telescopic rod 807 is fixedly arranged on the fixed block 808 provided at the top inside the second crushing box 4. Support blocks 811 fixedly connected to the inner side of the second crushing box 4 are provided at both the front and rear ends of the first movable rod 810. At one end of the fourth connecting rod 806, there are a telescopic rod 807 and a fixed block 808 with the same positional relationship corresponding to the first connecting rod 803;

[0033] The first movable rod 810 and the second movable rod 813 are correspondingly arranged. The other end of the fourth connecting rod 806 is sleeved on the bushing of the second main gear 814 provided outside the second movable rod 813. The fourth connecting rod 806, the third connecting rod 805, the second connecting rod 804, and the first connecting rod 803 are all sleeved on the bushings of several second driven gears 809. Several second driven gears 809 are meshed with the second main gear 814. Support blocks 811 with the same positional relationship as the second crushing box 4 are provided at the front and rear ends of the second movable rod 813. Fifth connecting rods 812 and sixth connecting rods 816 movably connected to the rear side central axes of the first crushing roll 801 and the second crushing roll 802 are respectively provided at the rear sides of the first movable rod 810 and the second movable rod 813. A second motor 815 is fixedly installed on the front side outside the second crushing box 4. The front end of the second movable rod 813 penetrates through the support block 811 and extends to the output end of the second motor 815.

[0034] Specifically, the second motor 815 drives the second movable rod 813 to rotate, thereby driving the second main gear 814 to rotate. Through the meshing transmission of a number of second driven gears 809, the synchronous counter-rotations of the two crushing rollers are achieved. The second main gear 814 and a number of second driven gears 809 are respectively sleeved on the bushings of the connecting rod system. When the second main gear 814 rotates, it drives all the second driven gears 809 to rotate through meshing transmission. When the distance between the first crushing roller 801 and the second crushing roller 802 is adjusted by the telescopic rod 807, the connecting rod system can adaptively adjust to meet the change in the distance between the crushing rollers, thereby achieving crushing that adapts to different particle size requirements.

[0035] During use, the material guide plate 502 guides the material in the feeding box 5 to smoothly enter the first crushing box 2. The first motor 705 is started, and the main rotating shaft 701 is driven to rotate through the bearing mounting seat 706. Through the cooperation of the first main gear 707 and the first driven gear 708 meshing with each other, the driven rotating shaft 703 is driven to rotate. The main crushing gear 702 on the main rotating shaft 701 cooperates with the driven crushing gear 704 on the driven rotating shaft 703 to achieve the relative rotation of the two crushing gears, thereby initially crushing the material entering the first crushing box 2. The material after initial crushing naturally falls into the second crushing box 4 through the transfer hopper 3. The second motor 815 is started to drive the second movable rod 813 to rotate. The second main gear 814 on the second movable rod 813 drives a number of second driven gears 809 meshing with it to rotate. The a number of second driven gears 809 transmit power to the first crushing roller 801 and the second crushing roller 802 through the connecting rod system, enabling them to rotate synchronously and counter-rotating to further crush the material, effectively reducing the coarse particle content in the finished product, increasing the proportion of fine particles, and achieving fine crushing of the rare earth ferrosilicon alloy raw material. At the same time, by adjusting the telescopic rod 807, the distance between the first crushing roller 801 and the second crushing roller 802 can be changed to adapt to crushing operations with different particle size requirements. The crushed material falls onto the discharge plate 9 through the discharge hopper 6 at the bottom of the second crushing box 4, completing the entire crushing and transmission process.
