[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0023] According to Figure 1 、 2 As shown in 3, 4, in this embodiment, a raw material conveyor for an extrusion machine is proposed, including a transportation pipeline 2.

The feeding bin 3 is communicated with the transportation pipeline 2 through the feeding pipe 4. A roller structure for crushing raw materials is provided in the feeding bin 3;

[0024] A material passing bin 5 is provided at the upper end of the transportation pipeline 2. The material passing bin 5 is fixedly connected to the transportation pipeline 2. The material passing bin 5 is communicated with the transportation pipeline 2. A spiral stirring part A for lifting raw materials upward is provided in the transportation pipeline 2;

[0025] The feeding bin 3 is arranged at the lower end of the transportation pipeline 2 and is set at a low position for convenient pouring of raw materials. A roller structure is arranged in the feeding bin 3, which can break up the lumps in the raw materials to avoid blockage when the raw materials are poured. During feeding, the spiral stirring part A in the transportation pipeline 2 will lift the materials upward into the material passing bin 5.

[0026] The lower end of the material passing bin 5 is provided with a discharge pipe 6. The discharge pipe 6 is placed on one side of the transportation pipeline 2. A spiral stirring part A for pouring the raw materials downward is arranged in the discharge pipe 6. The lower end of the discharge pipe 6 is provided with a bellows-shaped cover body 7, and the bellows-shaped cover body 7 is communicated with the discharge pipe 6.

[0027] The transportation pipeline 2 is placed on one side of the extrusion equipment. The discharge pipe 6 is moved above the hopper of the extrusion equipment. The materials lifted into the material passing bin 5 will be poured into the hopper at the top of the extrusion equipment through the discharge pipe 6 at the lower end of the material passing bin 5. The spiral stirring part B can adjust the discharging speed of the discharge pipe 6. When there is a height difference between the hopper and the discharge pipe 6, the bellows-shaped cover body 7 is pulled to expand the bellows-shaped cover body 7, and the bellows-shaped cover body 7 will extend into the hopper to avoid leakage of raw materials during feeding and ensure stable feeding.

[0028] The spiral stirring part A is used to lift the raw materials input at the bottom of the transportation pipeline 2 to its top. Specifically, the spiral stirring part A includes a first spiral blade 8 arranged in the material passing bin 5. The upper end of the first spiral blade 8 is rotatably connected to the top of the material passing bin 5, and the lower end of the first spiral blade 8 is rotatably connected to the top of the transportation pipeline 2. The upper end of the material passing bin 5 is provided with a first power part for controlling the rotation of the first spiral blade 8. The first power part controls the rotation of the first spiral blade 8. The first spiral blade 8 rotates to spin and push the materials at the bottom of the transportation pipeline 2 into the material passing bin 5 at the top of the transportation pipeline 2. As the rotation speed of the first spiral blade 8 increases, the lifting speed of the materials will also become faster.

[0029] The spiral stirring B is used to send the raw materials falling into the discharge pipe 6 out from the lower port of the discharge pipe 6. Specifically, the spiral stirring part B includes a second spiral blade 9 arranged in the material passing bin 5. The lower end of the second spiral blade 9 extends into the discharge pipe 6, and the upper end of the second spiral blade 9 is rotatably connected to the top of the material passing bin 5. The raw materials entering the material passing bin 5 will fall along the inclined plane at the bottom of the material passing bin 5 into the discharge pipe 6. When the second spiral blade 9 rotates, the second spiral blade 9 will push the raw materials out of the discharge pipe 6. As the rotation speed of the second spiral blade 9 increases, the discharging speed of the raw materials will also become faster.

The first gear 10 and the second gear 11 are connected by a synchronous belt 12.

[0032] The spiral stirring part A and the spiral stirring part B are controlled by the same power source. When the first motor 13 drives the second gear 11 to rotate, the second gear 11 will drive the first gear 10 to rotate together through the synchronous belt 12. Since the first spiral blade 8 is fixed to the second gear 11 and the second spiral blade 9 is fixed to the first gear 10, when the first gear 10 and the second gear 11 rotate, the first spiral blade 8 and the second spiral blade 9 will also rotate synchronously, realizing the feeding and discharging of raw materials.

[0033] Regarding the roller structure:

[0034] The roller structure includes two crushing rollers 16 arranged in the feeding bin 3. The two crushing rollers 16 are arranged side by side. The two ends of the crushing roller 16 are rotatably connected to the inner side wall of the feeding bin 3. A second power unit for controlling the rotation of the two crushing rollers 16 is provided outside the feeding bin 3. After the raw materials are put into the feeding bin 3, the two crushing rollers 16 will break up the lumps in the raw materials by rotating, improving the passing rate of the raw materials in the feeding pipe 4. Ribs that can increase the crushing effect of the raw materials are fixed outside the crushing roller 16.
