DETAILED DESCRIPTION

[0019] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0020] Figure 1 The overall cross-sectional structure of the mixing and stirring screw conveying integrated machine is schematically shown; Figure 2 The overall structure of the spiral axis is shown schematically. Figure 1-2 As shown, a mixing and stirring spiral conveying integrated machine includes a spiral shaft 7, which is driven by a transmission assembly, and the spiral shaft 7 is movably fixed in a housing 6, and the housing 6 is closed by a cover plate 8; the spiral shaft 7 includes a shaft body 73 and a front semicircular blade 77 and a rear semicircular blade 78 fixedly arranged on the shaft body 73, the front semicircular blade 77 and the rear semicircular blade 78 are connected end to end and are laterally supported by a support rod, and a plurality of stirring rods 76 are fixedly arranged between the front semicircular blade 77 and the rear semicircular blade 78. The front semicircular blade 77 and the rear semicircular blade 78 can not only pick up the material for the mixing process, but also form a complete spiral blade to play a conveying role, and the stirring rod 76 mainly plays a stirring role. In order to reduce the stirring resistance, the end of the stirring rod 76 can be provided with a chamfer.

[0021] The aforementioned support rods include a short support rod 74 and a long support rod 75. The short support rod 74 and the long support rod 75 are parallel to the shaft 73. Figure 3 The schematic diagram shows the local enlarged structure of area A, as shown in Figure 3 As shown, the short support rod 74 is fixedly arranged close to the connection point between the front semicircular blade 77 and the rear semicircular blade 78, and the long support rod 75 is fixedly arranged close to the side of the shaft body 73 away from the aforementioned connection point, and both ends of the long support rod 75 and the short support rod 74 are fixedly connected to the front semicircular blade 77 and the rear semicircular blade 78 respectively, which are used to assist the shaft body 73 in fixing and supporting the front semicircular blade 77 and the rear semicircular blade 78. The stirring rod 76 is vertically fixed based on the long support rod 75, and the spacing between adjacent stirring rods 76 is the same. The setting of the short support rod 74 and the long support rod 75 can not only play a supporting role to connect the front semicircular blade 77 and the rear semicircular blade 78 into one body, and enhance the strength of the blades of the spiral shaft 7, but also play a stirring role to make the mixing more uniform.

[0022] like Figure 1As shown, based on the aforementioned shaft body 73, the two ends are respectively provided with a head shaft 71 and a tail shaft 79, and an anti-spiral blade 72 is added on the shaft body 73 close to the head shaft 71, and the anti-spiral blade 72 has no contact with the front semicircular blade 77 or the rear semicircular blade 78. The transmission assembly includes a motor reducer 1 and a coupling 2, one end of the coupling 2 is connected to the rotating shaft of the motor reducer 1, and the other end is connected to the head shaft 71. It also includes a head frame 4, in which a head bearing 3 is fixedly arranged, and the head shaft 71 extends into the head bearing 3 and is connected to the coupling 2. It also includes a tail frame 9, in which a tail bearing 10 is fixedly arranged, and the tail shaft 79 extends into the tail bearing 10. The screw shaft 7 is supported and fixed by the head frame 4 and the tail frame 9. The head bearing 3 and the tail bearing 10 arranged in the head frame 4 and the tail frame 9 can make the screw shaft 7 rotate more smoothly. The motor reducer 1 and the coupling 2 are used to drive the rotation of the screw shaft 7, which can share the load of the screw shaft 7 to a certain extent and ensure the smooth operation of the mixing screw conveyor. The anti-spiral blade 72 can prevent the material from being pushed to the sealing component 5 at the head shaft 71, ensuring the discharge of the material and the normal operation of the mixing screw conveyor.

[0023] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
