[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. 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 implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0023] First embodiment:

[0024] See also Figure 1-Figure 2 As shown, the utility model provides a feeding tray for ferrosilicon raw materials, including a feeding tray 6, the feeding tray 6 is an inverted conical structure, and a plurality of discharge holes 601 are arranged on the surface of the feeding tray 6. When the material is guided downward from the discharge holes 601 on the feeding tray 6, when the material falls, the material is guided downward in a divergent state, and the material can be dispersed during the guiding process, so that the material can be discharged more evenly;

[0025] The utility model provides a feeding device for ferrosilicon raw materials, comprising a material box 1, a feeding plate 6 is detachably connected to the bottom surface of the material box 1, a feeding pipe 101 is arranged on the top surface of the material box 1, and a mixing component 2 is further included for mixing materials inside the material box 1 and assisting in discharging materials, the materials are guided into the material box 1 through the feeding pipe 101, the materials inside the material box 1 are mixed through the mixing component 2, the mixed materials fall onto the surface of the feeding plate 6, and the materials on the surface of the feeding plate 6 are operated to be transferred through the mixing component 2, and the auxiliary materials are discharged from the discharging hole 601;

[0026] Furthermore, there are multiple feeding pipes 101 to assist in feeding different materials. When multiple materials are used in combination, the multiple materials are fed through the feeding pipes 101 to assist in mixing the materials.

[0027] The second embodiment is different from the first embodiment in that:

[0028] The mixing component 2 includes a motor 202, the output end of the motor 202 is connected to a rotating shaft 201 extending into the interior of the material box 1, the outer side of the rotating shaft 201 is connected to a material holding plate 4 and a pushing rack 5, the material holding plate 4 and the pushing rack 5 correspond to the material box 1 and the unloading disc 6 respectively, and the pushing rack 5 and the unloading disc 6 have a clearance fit. After the motor 202 is energized, the motor 202 drives the rotating shaft 201 to rotate, and the rotating shaft 201 can drive the material holding plate 4 and the pushing rack 5 to rotate. The rotation of the material holding plate 4 can be used to mix the material inside the material box 1. After the pushing rack 5 rotates, due to the clearance fit between the pushing rack 5 and the unloading disc 6, the material on the unloading disc 6 can be pushed out by the pushing rack 5.

[0029] Furthermore, in the structure of the material receiving plate 4, the material receiving plate 4 is an inverted conical surface, and a material discharge hole 402 is penetrated at the lower end of the material receiving plate 4. A mixing rod 401 for mixing materials is provided on the surface of the material receiving plate 4. When the material receiving plate 4 is in a rotating state, the materials roll on the material receiving plate 4 toward the bottom end of the material receiving plate 4 due to gravity, and the mixing rod 401 rotates with the rotation of the material receiving plate 4. The materials on the surface of the material receiving plate 4 are mixed by using the mixing rod 401, and the materials finally fall to the surface of the material discharge plate 6 through the material discharge hole 402.

[0030] The outer side of the rotating shaft 201 is connected with a material guide plate 3, which is conical and located on the upper surface of the material holding plate 4. The lower end of the material guide plate 3 extends toward the upper end of the material holding plate 4, so as to guide the material.

When the pusher rack 5 rotates, the material shifting rods 501 rotate with the pusher rack 5 to adjust the material fluctuations.

[0032] The third embodiment is different from the first embodiment in that:

[0033] The side walls of the material box 1 and the lower box body 102 are both cylindrical. The lower box body 102 is connected to the bottom end of the material box 1, and the inner diameter of the lower box body 102 is smaller than the inner diameter of the feed pipe 101. The unloading plate 6 is connected to the bottom end of the lower box body 102 by a lock. The lock connection is used to realize the detachable connection between the unloading plate 6 and the pushing rack 5, and the material is also gathered by the lower box body 102 with a smaller inner diameter. The material inside the lower box body 102 is pushed by the material pusher rod 501 and the pushing rack 5, which can help the material to be evenly discharged from the discharge hole 601, thereby improving the unloading effect.
