    DETAILED DESCRIPTION OF THE EMBODIMENTS

    [0049] The following will clearly and completely describe the technical scheme in the embodiment of the disclosure with reference to the drawings in the embodiment of the disclosure, obviously, the described embodiment is only a part of the embodiment of the disclosure, not all the embodiments. Based on the examples in this disclosure, all other examples obtained by ordinary technicians in this field without creative work are within the scope of protection of this disclosure.

    [0050] As shown in FIG. 1, a multifunctional extruding-shearing machine includes a motor 12, a casing 1, a base 15, a rotor part and a stator component-cum-cover plate. Wherein, the casing 1 is a disk-shaped casing with a high edge, a rectangular discharge port 16 is arranged below the casing 1, the left end face of the casing 1 is fixedly connected to the motor 12, the right end face of the casing 1 has an annular flange connected to a stator part, and a motor 12 is fixed to a base 15, and the rotor part is fixed to the shaft of the motor 12 through a hub 11 by means of a shaft cap 10 and bolts.

    [0051] The rotor part includes a hub 11, a rotor disk 9 fixed on the hub 11, and one to three turns of several tens of the rotor pins 8 per turn mounted on the rotor disk 9, and the rotor pins 8 are uniformly distributed in a circumferential direction around the axis of the rotor disk 9.

    [0052] The stator component-cum-cover plate includes a stator disk 2 and one to three turns of several tens of the stator pins 5 per turn mounted on the stator disk 2, the stator pins 5 are uniformly distributed in a circumferential direction around the axis of the stator disk 2, and the center of the stator part is provided with a feed port 6. The stator disk 2 doubles as a cover plate.

    [0053] As shown in FIG. 2-3, the rotor pin 8 and the stator pin 5 have the same structure, and both of them include a quadrangular prismatic pin billet 23 and a wear-resistant member 22 welded or bonded to the pin billet 23. The wear-resistant member 22 is made of a cemented carbide or a special ceramic superhard wear-resistant material. The pin billet 23 is provided with a screw or polished rod connected with the rotor disk 9 or the stator disk 3. The inner horizontal surface and vertical surface of the wear-resistant member 22 are smooth planes, while the outer upper surface of the wear-resistant member 22 has 4-12 stepped teeth, and the lower surface consists of a right-angle table and a smooth slope, the inclined smooth plane of the lower surface merges with the lowest stepped surface of the upper surface in a spire shape, and the intersection is a transition of circular arc surface. The projected area of the outer upper surface of the wear-resistant member 22 in the vertical section passing through the axis of the pin billet 23 is more than three times that of the lower surface.

    [0054] The horizontal and vertical sides of the inner side of the wear-resistant member 22 are welded or glued to the adjacent two sides of the quadrangular prismatic pin billet 23. The wear-resistant component 22 of the present disclosure is made of superhard wear-resistant materials such as hard alloy or special ceramics, and ensures that the service life of the present disclosure is 3-5 times longer than that of the existing similar equipment.

    [0055] As shown in FIG. 4, when the disclosure is assembled, the stepped tooth surface of the stator pin 5 installed on the stator component faces inward, that is, the side close to the axis of the stator disk 2; the stepped tooth surface of the rotor pin 8 installed on the rotor component faces outward, that is, the side away from the axis of the rotor disk 9; and that step tooth tip of the rotor pin 8 face the step tooth tip of the stator pin 5. In other word, the side close to the axial center of the stator disk 2 and the side away from the axial center of the rotor disk,

    [0056] In operation of the present disclosure, material enters the space between the stator disk 2 and the rotor disk 9 in the housing technology 1 through the feed port 6. When the rotor part rotates to drive the material particles into the narrow space between the rotor pin 8 and the stator pin 5, the rotor pin must exert a huge squeezing and shearing force on the material particles clamped between the rotor pin 8 and the stator pin 5, forcing the material to be broken. The crushed material passes through the gap between the two stator pins and then is discharged through the discharge port 16.

    [0057] As shown in FIGS. 5-7, if the moment when a rotor pin 8 of the present disclosure approaches a stator pin 5 and leaves the stator pin 5 is regarded as a pin crushing operation, each pin crushing operation starts with the largest material particles clamped by the front step teeth of the rotor pin 8 and the stator pin 5. Since the rotor of the present disclosure operates at high speed so that each rotor pin 8 has a kinetic energy far exceeding the binding energy of the material particles, the largest material particles must be crushed rapidly. The state after the largest material particles have been crushed is shown in FIG. 6, the large and small material particles squeezed between the rotor pin 8 and the stator pin 5 are inevitably crushed successively by being subjected to the pressing and shearing forces exerted by the rotor pin 8, the stator pin 5 and the adjacent material particles. Until, as shown in FIG. 7, the material particles having a value slightly greater than L are crushed by clamping, in the foregoing, it is demonstrated that the extruding-shearing and crushing mode developed by the present disclosure and the high-speed extruding-shearing and crushing way has significant advantages such as huge force, extremely short operation time, extremely high crushing frequency and large crushing ratio.

    [0058] An application of a. multifunctional extruding-shearing machine in a grinding equipment, a gap between the rotor pin and the stator pin is L, and the value of L is between 0.2 and 1.5 mm; a linear velocity v of the rotor pin is between 50 m/s and 150 m/s. According to the obvious advantages of the structure and action principle of the disclosure and the test data of the prototype, it is proved that the disclosure applied to the grinding equipment has the potential to replace most existing grinding equipment, and at the same time has great advantages such as simple structure, low price, small occupied area, convenient installation and maintenance, long service life, high efficiency and energy saving, etc.

    [0059] An application of a multifunctional extruding-shearing machine in a crushing equipment, the value L of the gap between the rotor pin and the stator pin is equal to a product particle size value required by design; the linear velocity v of the rotor pin is between 5 m/s and 30 m/s. According to the obvious advantages of the structure and action principle of the disclosure and the test data of the prototype, it is proved that the application in a crushing equipment has obvious advantages such as high efficiency and energy saving.

    [0060] An application of a multifunctional extruding-shearing machine, the value L of the gap between the rotor pin and the stator pin is equal to a maximum kernel diameter value of plants to be processed; the linear velocity v of the rotor pin is between 2 m/s and 10 m/s. According to the obvious advantages of the structure and action principle of the present disclosure and the test data of the prototype test, it is proved that the greatest advantage of the present disclosure applied to the peeling equipment is that it can peel the skins of camellia seeds and hickory nuts that are difficult to peel in the prior art, and it has remarkable economic benefits.
