[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A twin-screw extruder special for plant fiber processing, including a motor, a box body, an extruder body and a bottom plate. The bottom of the motor is fixedly connected with a side plate through bolts and two first blocks. One side of the side plate is fixedly connected with one side of the bottom plate. The output shaft of the motor is fixedly connected with a rotating column. One end of the rotating column extends into the interior of the box body and is fixedly connected with a gear. A plurality of gears for driving the extruder body are arranged inside the box body, and the plurality of gears are meshed with each other. The bottom of the box body is fixedly connected with the top of the bottom plate. The bottom of the extruder body is fixedly connected with the top of the bottom plate through a rectangular plate. The extruder body is provided with a feeding end and a discharging end;

[0007] A blanking mechanism, which is arranged on the bottom plate and used for blanking the processed raw materials.

[0008] In a possible design, the blanking mechanism includes a discharge box, two connecting plates, an arc-shaped plate, two sliding frames, a shielding plate, a side frame, and a storage box. The bottom of the discharge box is fixedly connected to the top of the bottom plate. Feed inlets and discharge outlets are provided on both sides of the discharge box. The feed inlets are connected to the discharge ends of the extruder bodies. The two sides of the same arc-shaped plate are fixedly connected to the closer sides of the two connecting plates. The two connecting plates and the arc-shaped plate are all disposed at the bottom of the same discharge outlet and penetrate through the discharge outlet to extend to one side of the discharge box. The two connecting plates and the arc-shaped plate are all inclined. The shapes of the two sliding frames are both L-shaped. The two sliding frames are respectively fixedly connected to both sides of one side of the discharge box. The two inner walls of the two sliding frames are slidably connected to both sides of the shielding plate. A first handle for facilitating the opening of the discharge box is fixedly connected to one side of the shielding plate. One side of the side frame is fixedly connected to one side of the bottom plate. The side frame is located below the arc-shaped plate. The top of the storage box is an open area. The storage box is disposed on the top of the side frame. A second handle for facilitating the movement of the storage box is fixedly connected to one side of the storage box.

[0009] In a possible design, a fixing hole is provided on the shielding plate. A fixing column is threadedly connected to the inner wall of the fixing hole. One end of the fixing column is in close contact with one side of the discharge box. A rotating handle for facilitating the rotation of the fixing column is fixedly connected to the other end of the fixing column.

[0010] In a possible design, the top of the discharge box is an open area. A top cover for facilitating the cleaning and maintenance of the interior of the discharge box is fixedly connected to the top of the discharge box by bolts.

[0011] In a possible design, a triangular block for facilitating the movement of the storage box is fixedly connected to one side of the side frame.

The top of the feed channel is in a horn shape for facilitating the feeding of raw materials. A cover plate for preventing raw material splashing is placed on the top of the feed channel. A third handle for facilitating the holding of the cover plate is fixedly connected to the top of the cover plate.

[0013] In this application, during use, the motor is started by an external controller. The motor drives the rotating column through the output shaft, thereby driving multiple gears to rotate, and then driving the twin-screw of the extruder body to rotate. Then, the cover plate is removed by the third handle. The plant fiber raw material is put into the extruder body from the feeding channel, and then the cover plate is covered. The extruder body processes the raw material, discharges it at the discharge end, and discharges it into the discharge box. The processed raw material is poured out through the inclined connecting plate and arc plate on the discharge box. Then, the two sides of the baffle are slid in the sliding frame by the first handle, thereby opening the discharge port. Then, the baffle is fixed to one side of the discharge box by the fixing column. Then, the raw material is collected in the storage box on the side frame, and the processed raw material is transported to the next processing area by the second handle. The arranged triangular block facilitates the movement of the storage box. At the same time, when moving the storage box, the discharge port can be blocked by the baffle. When replacing the storage box, it is not necessary to turn off the machine, thereby ensuring that the raw material does not fall and also ensuring the processing efficiency of the raw material. After the replacement is completed, the baffle is opened and fixed to facilitate the collection of the processed raw material.

[0014] The beneficial effects of the present utility model are as follows:

[0015] In the present utility model, through the feeding mechanism, it is not necessary to use additional tools to collect and place the processed raw material, improving the practicability of the machine. And when it is necessary to replace the collection container, it can be temporarily blocked by the baffle, and it is not necessary to turn off the machine, improving the processing efficiency of the raw material.
