Two support shafts are rotatably connected to the front and rear inner walls of the crushing box. The two support shafts are arranged in parallel. Crushing rollers are fixedly connected to the outer walls of the support shafts. The two crushing rollers are in clearance fit. The rear ends of the two support shafts both penetrate through the rear side wall of the crushing box and are fixedly connected with gears. The two gears are meshed with each other. The two gears are in clearance fit with the outer wall at the rear side of the crushing box. A first motor is fixedly connected to the front side wall of the crushing box. The output shaft of the first motor is fixedly connected to the front end of one of the support shafts. A feeding hopper is fixedly and communicatively connected to the bottom of the crushing box. A feeding pipe is fixedly and communicatively connected to the bottom of the feeding hopper. The feeding pipe extends to the right. A rotating shaft is rotatably connected between the left and right inner walls of the feeding pipe. The feeding pipe is divided into three sections. There is a sleeve between two adjacent feeding pipes. The two adjacent feeding pipes are respectively threadedly sleeved on the two ends of the sleeve. A feeding auger is fixedly connected to the outer wall of the rotating shaft. The feeding auger corresponds to the three sections of the feeding pipe. There is a grinding roller inside each sleeve. The grinding roller is fixedly connected to the outer wall of the rotating shaft. A discharging pipe is fixedly and communicatively connected to the bottom at the right end of the feeding pipe.

[0008] Advantages of the Present Utility Model
[0009] Through the preliminary crushing by the crushing roller and the fine grinding process in the feeding pipe, the utility model can effectively crush materials and improve the smelting efficiency. The feeding pipe is divided into three sections, and the sleeves between each section provide an additional grinding effect, enabling the materials to be ground more finely, which is beneficial to the subsequent smelting process. By adjusting the number and position of the sleeves, the number and degree of grinding can be changed to meet the needs of different materials. The rotation of the feeding auger not only promotes the transportation of the materials but also increases the grinding effect of the materials, improving the crushing effect of the entire device.

SPECIFIC EMBODIMENTS
[0017] As Figures 1-6As shown: A feeding device for a low-carbon ferrochrome smelting equipment, including a bracket 1, the top of the bracket 1 is fixedly connected with a crushing box 2; two support shafts 3 are rotatably connected to the front and rear inner walls of the crushing box 2, the two support shafts 3 are arranged in parallel, the outer walls of the support shafts 3 are fixedly connected with crushing rollers 4, the two crushing rollers 4 are in clearance fit, the rear ends of the two support shafts 3 penetrate through the rear side wall of the crushing box 2 and are fixedly connected with gears 6, the two gears 6 are meshed with each other, the two gears 6 are in clearance fit with the outer wall of the rear side of the crushing box 2, the front side wall of the crushing box 2 is fixedly connected with a first motor 5, the output shaft of the first motor 5 is fixedly connected with the front end of one of the support shafts 3, the bottom of the crushing box 2 is fixedly communicated with a feeding hopper 7, the bottom of the feeding hopper 7 is fixedly communicated with a feeding pipe 8, the feeding pipe 8 extends to the right, a rotating shaft 9 is rotatably connected between the left and right inner walls of the feeding pipe 8, the feeding pipe 8 is divided into three sections, there is a sleeve 12 between two adjacent feeding pipes 8, the two adjacent feeding pipes 8 are respectively threadedly sleeved with the two ends of the sleeve 12, the outer wall of the rotating shaft 9 is fixedly connected with a feeding auger 10, the feeding auger 10 is divided into three sections corresponding to the three sections of the feeding pipe 8, there is a grinding roller 11 inside each sleeve 12, the grinding roller 11 is fixedly connected with the outer wall of the rotating shaft 9, the bottom of the right end of the feeding pipe 8 is fixedly communicated with a discharging pipe 13, the left end of the feeding pipe 8 is fixedly connected with a second motor 14, the output shaft of the second motor 14 is fixedly connected with the left end of the rotating shaft 9, and there is a receiving box 15 below the discharging pipe 13.

[0019] When the material is put into the crushing box 2, the first motor 5 is started to drive the support shaft 3 connected thereto to rotate. Due to the meshing of the two gears 6, the other support shaft 3 will also rotate simultaneously. In this way, the two crushing rollers 4 will rotate relatively to crush the material, and the crushed material will fall into the lower feeding hopper 7 through the gap between the crushing rollers 4.
[0020] After the material enters the feeding hopper 7, it will enter the feeding pipe 8. The second motor 14 is started to drive the rotating shaft 9 to rotate. Since the outer wall of the rotating shaft 9 is fixedly connected with a feeding auger 10, the rotation of the auger will push the material to move to the right. At the same time, the feeding pipe 8 is divided into three sections, and each section is connected by a sleeve 12.

[0021] The finely ground material will ultimately reach the right end of the feeding pipe 8 and enter the material receiving device 15 through the blanking pipe 13, preparing for further processing or feeding into the smelting furnace. The present utility model only protects the mechanical part, and the functions realized by the software control part related thereto are not within the scope of protection of the present utility model.
