In this embodiment, the upper surface of driving-disc 2 is provided with anti-skidding line, and it drives the material rotation of being convenient for.

In this embodiment, the crushing and mixing device further includes a driving motor 5, the driving motor 5 is fixedly connected with the frame 10, and the driving disk 2 is mounted on an output shaft of the driving motor 5 to rotate under the driving of the driving motor 5. Driving-disc 2 can slide from top to bottom along driving motor 5's output shaft, and detachable is provided with the location retaining member (not shown in the figure) on driving motor 5's the output shaft, and the location retaining member makes driving-disc 2 closely laminate with the lower terminal surface of shell 1 at broken in-process that grinds, can remove the location retaining member after the breakage, and pull-down driving-disc 2, the material of being convenient for falls into mixing chamber 9.

In the present embodiment, the number of the crushing frames 3 is preferably 6, and the number of the respective crushing plates 4 is 6. In the initial state, as shown in fig. 1, 2, 3 and 7, all the crushing plates 4 and the first frame plate 301 of the crushing frame 3 form a hexagram mechanism, and two materials are respectively put into the first crushing area and the second crushing area. In the present invention, the driving motor 5 is first rotated counterclockwise in conjunction with the connection of the crushing frame 3 and the crushing plate 4.

And starting the driving motor 5, driving the driving disc 2 to rotate anticlockwise by the driving motor 5, and driving the material to rotate anticlockwise by the driving disc 2. Along with mutual extrusion collision between the mobile material of material, broken post 6 is broken the internal material with the cooperation of crushing shell 4 and broken frame 3, and the inner wall of shell 1 is broken the external material with the cooperation of crushing shell 4 and broken frame 3.

During the rotation and crushing of the materials, the external materials push the second frame plate 302 inwards, so that the hexagram mechanism formed by the first frame plate 301 and the crushing plate 4 tends to contract inwards. The inner material pushes the crushing plate 4 outwards, so that the hexagram mechanism formed by the first frame plate 301 and the crushing plate 4 tends to expand outwards. Due to the fact that materials are uneven, the hexagonal star mechanism contracts and expands outwards continuously, gaps between the third frame plate 306 and the crushing plate 4 become larger and smaller continuously, and smaller materials are clamped into the gaps and are further crushed by the third frame plate 306 and the crushing plate 4. It should be noted that, in the initial state, the gap between the crushing plates 4 of the third frame plate 306 may not exist, and the existence of the gap in the initial state is more convenient for the external expansion of the hexagram mechanism.

As the material in the gap is more and more blocked, the outward expansion of the hexagram mechanism is more and the contraction is less in the contraction and outward expansion process, so that the hexagram mechanism is continuously and integrally expanded (as shown in fig. 8). In the expanding process of the hexagram mechanism, the rear end of the second frame plate 302 swings outwards relative to the front end along the counterclockwise direction, the inward acting force of the outer material on the second frame plate 302 gradually becomes smaller (the acute angle formed by the second frame plate 302 and the outer material speed direction becomes smaller and smaller), similarly, the front end of the crushing plate 4 swings outwards relative to the rear end, the outward acting force of the inner material on the crushing plate 4 becomes smaller (the acute angle formed by the crushing plate 4 and the inner material speed direction becomes smaller and smaller), the acting force of the third frame plate 306 swinging outwards counterclockwise relative to the first hinge shaft 8 by the material in the gap between the third frame plate 306 and the crushing plate 4 continuously increases (the difference between the acute angle formed by the third frame plate 306 and the material speed direction and 90 degrees becomes smaller and smaller), until the acting force of the third frame plate 306 swinging outwards counterclockwise by the material in the gap is larger than the inward acting force of the outer material on the second frame plate 302, at this time, the inner material is considered to be crushed qualified, the acting force applied to the crushing frame 3 and the crushing plate 4 is small, and the hexagonal star mechanism is pushed to expand outwards mainly by the acting force of the counterclockwise outward swinging of the third frame plate 306 caused by the accumulation of materials in the gap until the state of fig. 9 is changed. At this time, the crushing plate 4 and the first frame plate 301 hinged by the first hinge shaft 8 are coplanar, the insertion part 801 is aligned with and clamped into the wedge hole 308, so that the crushing plate 4 and the first frame plate 301 are locked, the hexagram mechanism becomes hexagonal and remains unchanged, and the space enclosed by the third frame plate 306, the crushing plate 4, the second frame plate 302 and the inner wall of the shell 1 connected in sequence in the second crushing area gradually becomes smaller along the clockwise direction.

Then, the driving motor 5 rotates reversely (rotates clockwise), the driving disc 2 drives the material to rotate clockwise, and the material is further crushed by matching the outermost end (the hinge point of the second frame plate 302 and the third frame plate 306) of the crushing frame 3 with the shell 1; and after the external material is qualified, stopping the driving motor 5, pulling down the driving disc 2, starting the driving motor 5 again, mixing the internal material and the external material along with the rotation of the driving motor 5, throwing the internal material and the external material into the mixing cavity 9 (the outer diameter of the mixing cavity 9 is larger than that of the shell 1), and then further mixing to prepare the material for standby. After mixing, reset first articulated shaft 8, driving-disc 2 and reset, can restart broken compounding. If the material to be crushed is changed, the telescopic length of the second frame plate 302 can be adjusted to accommodate different kinds of materials.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
