[0017] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0018] See Figures 1-3 The two-degree-of-freedom four-bar clay refining mechanism shown includes a housing 10, a drive unit 20, and a refining unit 30. The drive unit 20 is installed inside the housing 10, and the refining unit 30 is installed at the front end of the drive unit 20.

[0019] The shell 10 includes a cylinder 11, a constriction area 12, a discharge port 13, a feed port 14, and a cover plate 15. The front end of the cylinder 11 has a constriction area 12, the diameter of which gradually decreases from the cylinder 11, making the output mud more compact. The front end of the constriction area 12 is connected to the discharge port 13. The upper rear part of the cylinder 11 has a feed port 14, from which the mud is conveyed into the refining mechanism. The rear end of the cylinder 11 has a cover plate 15, on which a drive unit 20 is installed.

[0020] The drive unit 20 includes a rotating shaft 21, an auger blade 22, a bevel gear 23, and a bushing 24. The rotating shaft 21 is hinged to the cover plate 15 and extends into the housing 10. The auger blade 22 is installed on the rotating shaft 21. The area of ​​the auger blade 22 extends forward from below the feed inlet 14 to the middle section of the cylinder 11. The auger blade 22 continuously conveys the mud from the feed inlet 13 forward for refining in the subsequent refining unit 30. The bevel gear 23 is installed at the front of the rotating shaft 21 and is connected to the refining unit 30. The bushing 24 is installed at the front end of the rotating shaft 21 and is connected to the refining unit 30.

[0021] The refining section 30 includes a main connector 31, a hinged bracket 32, a front boss 33, a two-dimensional stirring section 34, and a revolving stirring section 35. The main connector 31 has an inclined hinged bracket 32 ​​on each side inside. The two-dimensional stirring section 34 is hinged to the hinged bracket 32. The front boss 33 is located at the front end of the main connector 31, and a rotating shaft 21 is mounted on the front boss 33 via a bushing 24. The two-dimensional stirring section 34 includes a driven gear 341, double-sided rods 342, and a driven shaft 343. The driven shaft 343 is hinged to the hinged bracket 32, and the driven gear 341 is mounted on the driven shaft 343. The driven gear 341 meshes with a bevel gear 23 for transmission. The double-sided rods 342 are mounted at the front end of the driven shaft 343. Located on both sides of the driven shaft 343, the driven shaft 343 rotates to stir the mud, reducing / eliminating air bubbles in the mud. A revolving stirring part 35 is installed on each side of the main joint 31. The revolving stirring part 35 includes an overlapping plate 351, a diagonal rod 352, and a single-sided rod 353. The overlapping plate 351 is installed on the side wall of the main joint 31. The installation of the overlapping plate 351 on the side wall of the main joint 31 can be a firm connection method such as welding, riveting, or screwing. The overlapping plate 351 is connected forward to the diagonal rod 352. The single-sided rod 353 is installed at the end of the diagonal rod 352. The outer end of the single-sided rod 353 is as close as possible to the inner wall of the cylinder 11 to maximize the stirring range and ensure the refining effect of the mud.

[0022] Of course, it should also be noted that this embodiment requires a necessary support structure and a suitable power source. The support structure supports the entire device on the ground or workbench, and the power source is connected to the rotating shaft 21 and drives the rotating shaft 21 to rotate, providing rotational power for the entire device to realize the mud refining operation.

[0023] In addition, if necessary, a vacuum device can be added inside the cylinder 11. The vacuum device is not an innovation of this embodiment and will not be described in detail here.

[0024] The working principle of this invention is as follows: the clay to be refined is fed into the cylinder 11 through the feed port 14, the rotating shaft 21 drives the auger blades 22 to rotate, and the rotating auger blades 22 push the clay forward. When the clay is transported to the refining section 30, it is fully stirred by the various stirring components of the refining section 30 to remove the air mixed in with the clay. Then the clay passes through the closing area 12 to further densify the clay, and finally it is output through the discharge port 13.

[0025] The rotating shaft 21 is driven to rotate by a power source. The bevel gear 23 on the rotating shaft 21 drives the driven gears 341 on both sides to rotate through gear meshing. The driven gears 341 drive the double-sided rods 342 to rotate, stirring and refining the mud. At the same time, the rotating shaft 21 drives the main joint 31 to rotate through the bushing 24. The rotation of the main joint 31 drives the single-sided rod 353 of the revolving stirring part 35 to rotate as a whole, further stirring and refining the mud. Meanwhile, the two-dimensional stirring part 34 rotates in a circle along with the main joint 31 while its double-sided rods 342 rotate. Therefore, the double-sided rods 342 rotate on their own axis and also revolve around the center, which is a two-dimensional rotation, greatly improving the efficiency of stirring and refining.

[0026] The above embodiments primarily illustrate the dual-degree-of-freedom four-bar clay refining mechanism of the present invention. Although only a limited number of embodiments and technical features have been described, those skilled in the art should understand that the present invention can be implemented in many other forms without departing from its spirit and scope. Therefore, the illustrated embodiments are considered illustrative rather than limiting, and the invention may encompass various modifications and substitutions without departing from the spirit and scope of the invention as defined by the appended claims.
