[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0032] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0033] Example 1

[0034] Reference Figure 1 This embodiment provides a vibratory motor for coal mine feeding, including a power assembly 100, including a motor 101, and a rotating shaft 102 connected to the output shaft of the motor 101; the connection between the output shaft of the motor 101 and the rotating shaft 102 is a coupling connection.

[0035] It also includes a vibration assembly 200 for generating vibration force. It includes a first eccentric block 201 and a second eccentric block 202 disposed on the outside of the rotation shaft 102 and coaxially disposed with the rotation shaft 102. The first eccentric block 201 and the second eccentric block 202 have completely identical structural shapes and are semi-circular structures.

[0036] In this embodiment, the first eccentric block 201 and the second eccentric block 202 can form a complete ring and be fitted around the rotating shaft 102. At this time, the center of gravity of the rotating shaft 102 and the vibration component 200 is on the axis of the rotating shaft 102, and no vibration force is generated. The positions of the first eccentric block 201 and the second eccentric block 202 can be changed. When the positions of the first eccentric block 201 and the second eccentric block 202 are arranged side by side, the first eccentric block 201 and the second eccentric block 202 form the effect of an "eccentric shaft" and can generate vibration force.

[0037] Example 2

[0038] Reference Figures 1-7 This is the second embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that:

[0039] The rotating shaft 102 is a hollow shaft, and a first long groove 102a and a second long groove 102b extending axially are provided on the rotating shaft 102. The first long groove 102a and the second long groove 102b have the same length. The second long groove 102b is located on the opposite side of the first long groove 102a. A first strip groove 102c extends circumferentially from the end of the first long groove 102a, and a second strip groove 102d extends circumferentially from the end of the second long groove 102b. The first long groove 102a and the first strip groove 102c are connected in an L-shape, and the second long groove 102b and the second strip groove 102d are connected in an L-shape.

[0040] The first long groove 102a and the second long groove 102b are located on the same axial section, and the ends of the first strip groove 102c and the second strip groove 102d are located on the same axial section and on the same side of the rotating shaft 102. Therefore, two L-shaped grooves are formed on the rotating shaft 102.

[0041] In this embodiment, a virtual plane A is defined, wherein the axis of rotation 102 is perpendicular to plane A, and the second plane B is the axial section where the end of the strip groove 102d is located. The second long groove 102b and the second strip groove 102d should satisfy the following: the second long groove 102b is located at the position where the first long groove 102a is mirrored with plane A and then mirrored with plane B, and the second strip groove 102d is located at the position where the first strip groove 102c is mirrored with plane A and then mirrored with plane B.

[0042] Furthermore, a first pin 201a is provided on the inner side of the first eccentric block 201. The first pin 201a is embedded in the first long groove 102a and the first strip groove 102c. When the first pin 201a is located in the first long groove 102a, the first eccentric block 201 moves linearly. When the first pin 201a is located in the first strip groove 102c, the first eccentric block 201 moves in a circular motion.

[0043] Similarly, a second pin 202a is provided on the inner side of the second eccentric block 202. The second pin 202a is embedded in the second long groove 102b and the second strip groove 102d, and the second eccentric block 202 can also perform linear or circular motion.

[0044] The central angle of the first groove 102c and the second groove 102d is 90°. Therefore, the maximum deflection range of the first eccentric block 201 and the second eccentric block 202 is 90°, and the relative maximum deflection angle of the first eccentric block 201 and the second eccentric block 202 is 180°.

[0045] When the first pin 201a is located in the first groove 102c and the second pin 202a is located in the second groove 102d, the first eccentric block 201 and the second eccentric block 202 are parallel and their end faces are in contact. At this time, the center of gravity of the rotating shaft 102 and the vibration assembly 200 is not on the axis of the rotating shaft 102, and vibration force can be generated.

[0046] When the first pin 201a is located in the first long groove 102a and the second pin 202a is located in the second long groove 102b, the side of the first eccentric block 201 coincides with the side of the second eccentric block 202. If the first pin 201a moves to the end of the first long groove 102a and the second pin 202a moves to the end of the second long groove 102b, that is, the first eccentric block 201 and the second eccentric block 202 approach each other, the end faces and side faces of the first eccentric block 201 and the second eccentric block 202 completely coincide, and the first eccentric block 201 and the second eccentric block 202 form a complete ring structure. The center of gravity of the rotating shaft 102 and the vibration component 200 is on the axis of the rotating shaft 102, and the rotating shaft 102 has no radial vibration force.

[0047] Furthermore, a first rotating cylinder 203 and a second rotating cylinder 204 are provided inside the rotating shaft 102, both of which are capable of rotation. In this embodiment, an annular groove 102e is provided inside the rotating shaft 102, and both the first rotating cylinder 203 and the second rotating cylinder 204 are provided with limiting protrusions located within the annular groove 102e. Therefore, the first rotating cylinder 203 and the second rotating cylinder 204 cannot be axially offset.

[0048] The first rotating cylinder 203 has a first inclined groove 203a on its outer periphery, and the first pin 201a is embedded in the first inclined groove 203a. The second rotating cylinder 204 has a second inclined groove 204a on its outer periphery, and the second pin 202a is embedded in the second inclined groove 204a. The direction of the first inclined groove 203a is neither on the axial section of the first rotating cylinder 203 nor on the vertical plane of the axial section of the first rotating cylinder 203. The inclination direction of the first inclined groove 203a satisfies the following: when the first pin 201a is located in the first long groove 102a and the first inclined groove 203a, the first rotating cylinder 203 rotates and moves the first eccentric block 201 in a straight line; when the first pin 201a is located in the first strip groove 102c and the first inclined groove 203a, the first rotating cylinder 203 rotates and deflects the first eccentric block 201 along the axis.

[0049] It should be noted that the motion principle of the second rotating cylinder 204 and the second eccentric block 202 is the same as that of the first rotating cylinder 203 and the first eccentric block 201. Furthermore, in order to satisfy the combined configuration of the first eccentric block 201 and the second eccentric block 202, i.e., the movements of the first eccentric block 201 and the second eccentric block 202 are always opposite, the rotation directions of the first rotating cylinder 203 and the second rotating cylinder 204 should also be opposite.

[0050] To ensure that the first rotating cylinder 203 and the second rotating cylinder 204 rotate in opposite directions, an adjusting shaft 205 is included. The adjusting shaft 205 passes through the first rotating cylinder 203 and the second rotating cylinder 204. The first rotating cylinder 203 has a first spiral groove 203b on its inner side, and the second rotating cylinder 204 has a second spiral groove 204b on its inner side. The adjusting shaft 205 has a first frustum 205a and a second frustum 205b. The first frustum 205a is embedded in the first spiral groove 203b, and the second frustum 205b is embedded in the second spiral groove 204b. The first spiral groove 203b and the second spiral groove 204b rotate in opposite directions. The adjusting shaft 205 itself can only move axially and cannot rotate. Therefore, when the adjusting shaft 205 moves in a straight line, it drives the first rotating cylinder 203 and the second rotating cylinder 204 to rotate in opposite directions, thereby driving the first eccentric block 201 and the second eccentric block 202.

[0051] Preferably, the first rotating cylinder 203 and the second rotating cylinder 204 are connected by a bearing (a conventional means, not shown in the figure), so that the first rotating cylinder 203 and the second rotating cylinder 204 do not affect each other even if they rotate in opposite directions.

[0052] It should be noted that, such as Figure 6 As shown, to prevent the first eccentric block 201 and the second eccentric block 202 from falling off, the first inclined groove 203a and the second inclined groove 204a are both provided with T-shaped grooves. The T-shaped grooves are aligned with the first inclined groove 203a and the second inclined groove 204a. At the same time, the ends of the first pin 201a and the second pin 202a are provided with T-shaped bosses, which are embedded in the corresponding T-shaped grooves.

[0053] Furthermore, the rotating shaft 102 is provided with a moving groove 102f extending axially, and the adjusting shaft 205 is provided with a connecting rod 205c passing through the moving groove 102f. A drive ring 206 is externally connected to the rotating shaft 102, and the drive ring 206 is threadedly connected to the rotating shaft 102. A groove 206a is provided on the inner side of the drive ring 206, and the connecting rod 205c is embedded in the groove 206a. That is, the axial movement of the rotating shaft 102 is offset by the drive ring 206, thereby driving the first rotating cylinder 203 and the second rotating cylinder 204 to rotate.

[0054] In this embodiment, the vibration component 200 of the vibration motor includes three modes. The first mode is when the vibration force generated by the vibration component 200 is the maximum. In this mode, the first eccentric block 201 and the second eccentric block 202 are located on the same side of the rotating shaft 102, and the end faces and side faces of the first eccentric block 201 and the second eccentric block 202 coincide. The first pin 201a is located at the end of the first slot 102c, and the second pin 202a is located at the end of the second slot 102d. The second mode is when the center of gravity of the vibration component 200 and the rotating shaft 102 is located on the axis of the rotating shaft 102, and no vibration force is generated. In this mode, the first eccentric block 201 and the second eccentric block 202 form a complete ring sleeve outside the rotating shaft 102. The first pin 201a is located at the end of the first long slot 102a, and the second pin 202a is located at the end of the second long slot 102b. The third mode is the intermediate state between the first mode and the second mode. The specific position can be adjusted by the drive ring 206.

[0055] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
