Description

Technical Field

[0001] The invention relates to the technical field of motor manufacturing, and in particular to a wide-voltage motor for animal husbandry equipment. Background Art

[0002] In livestock feed feeding equipment, the use of eccentric block vibration motors can prevent the feed from accumulating and clogging after mixing. In the feeding process, as the amount of feed changes, the amplitude needs to be adjusted to prevent the vibration amplitude from being too large to damage the equipment when there is not much feed left. The amplitude modulation efficiency of the vibration motor using manual amplitude modulation is low, which affects work efficiency. The automatic amplitude modulation motor often uses a dual motor to drive the eccentric block to adjust the angle. Its limitation lies in the high requirements for the adaptability range of voltage width, which is not suitable for livestock equipment with long operating time and poor voltage stability. In addition, the principle of using the existing amplitude modulation motor is that the motor shaft drives the gear to drive the eccentric block to rotate, and the angle of the eccentric block is locked by the motor's locking performance on the output shaft. This leads to the disadvantage of relative rotation of the eccentric block when the motor output shaft lock fails, resulting in insufficient stability, especially for eccentric blocks with large loads. Summary of the invention

[0003] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a wide-voltage motor for livestock equipment, which has a wider adaptability range for the input voltage of the motor and has the advantage of high stability.

[0004] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] a casing, wherein the first eccentric disc and the second eccentric disc are arranged in the casing;

[0007] A driving frame and a pneumatic cylinder, wherein the pneumatic cylinder is mounted on the housing and is in driving connection with the driving frame, and the pneumatic cylinder is used to drive the driving frame to reciprocate along the axial direction of the rotating output shaft;

[0008] A one-way transmission device, which is used to drive the second eccentric disk to rotate unidirectionally around direction a during the reciprocating movement of the driving frame, and the one-way transmission device includes:

[0009] An annular gear plate installed on the driving frame, the annular gear plate is arranged on the side of the second eccentric plate close to the first eccentric plate, the annular gear plate is provided with a group of first driving helical teeth, the group of first driving helical teeth is in a circumferentially spaced array, and a first limiting groove is provided between an adjacent pair of first driving helical teeth;

[0010] A group of second driving helical teeth, wherein the second driving helical teeth are arranged on the first eccentric disk near one end of the second eccentric disk, the group of the second driving helical teeth are in a circumferentially spaced array, a second limiting groove is provided between an adjacent pair of the second driving helical teeth, and the first eccentric disk is fixed on the rotating output shaft;

[0012] A second transmission bevel tooth corresponding to the second driving bevel tooth, the second transmission bevel tooth being arranged on the second eccentric disk near one end of the first eccentric disk, and the width of the second transmission bevel tooth being adapted to the second limiting groove;

[0013] The second eccentric disk is sleeved on the rotating output shaft, and one end of the second eccentric disk away from the annular gear disk abuts against the first spring.

[0014] Based on the above device, a wide voltage motor for livestock equipment in this application has the following principle:

[0015] In the reset state, the first driving bevel teeth are separated from the first transmission bevel teeth, the second transmission bevel teeth are arranged in the second limiting groove, and the first spring is used to limit the axial position of the second eccentric disk. At this time, when the output shaft rotates, the first eccentric disk can drive the second eccentric disk to rotate together, and the first transmission bevel teeth do not contact the first driving bevel teeth during the rotation of the second eccentric disk.

[0016] When adjusting the amplitude, first, the pneumatic cylinder drives the driving frame to move toward the side of the second eccentric disk. During this process, the first driving bevel gear conflicts with the first transmission bevel gear, thereby pushing the second eccentric disk to move axially. When the second eccentric disk moves to the point where the second transmission bevel gear moves out of the second limiting groove, due to the extrusion force of the first spring, the bevel gear surfaces between the first driving bevel gear and the first transmission bevel gear are circumferentially staggered, so that the second eccentric disk rotates around the direction a by a preset angle so that the second transmission bevel gear is staggered with the circumferential position of the originally corresponding second limiting groove; then, the pneumatic cylinder moves in the opposite direction to the reset state. During this process, the first spring pushes the second eccentric disk to the point where the second transmission bevel gear conflicts with the second driving bevel gear, and the bevel gear surfaces between the second transmission bevel gear and the second driving bevel gear are circumferentially staggered, so that the second eccentric disk rotates around the direction a until the second transmission bevel gear enters the next second limiting groove; therefore, the rotation of the second eccentric disk relative to the first eccentric disk is realized, thereby adjusting the amplitude. The pneumatic cylinder reciprocates once, and the amplitude is adjusted by one unit. The controller can be used to control the pneumatic cylinder to reciprocate multiple times continuously to adjust the amplitude to the preset requirements.

[0021] The second driving helical tooth comprises a second driving helical tooth surface and a second limiting tooth surface, and the second limiting tooth surface is coplanar with the side surface of the second limiting groove. As a preferred solution of the present application, the first driving helical tooth surface and the second driving helical tooth surface are used to convert the axial pressure into the circumferential torque, and the rotation direction is from the high position to the low position of the helical tooth surface, and the first limiting tooth surface and the second limiting tooth surface are used to limit the driving helical tooth entering the limiting groove.

As a preferred embodiment of the present application, the traditional eccentric block is fan-shaped, which makes it impossible to evenly set the first transmission bevel teeth on the outer side of the circumference, which will cause the second eccentric disk to be unevenly stressed when the annular gear disk drives the second eccentric disk to move, resulting in poor stability in driving the second eccentric disk to move and rotate, affecting the service life of the second eccentric disk. In the present application, in order to ensure the symmetry of the force transmitted to the second eccentric disk, the fan-shaped frame is symmetrically arranged on the eccentric disk body, and the first transmission bevel teeth are symmetrically arranged on the eccentric disk body and the fan-shaped frame to ensure the symmetry of the force on the second eccentric disk, so as to improve the stability of the movement and rotation of the second eccentric disk.

[0027] When the second transmission bevel gear is aligned with the second limit groove, the brake disc moves to separate from the first eccentric disc. As a preferred solution of the present application, the circumferential rotation of the second eccentric disc during the amplitude adjustment may drive the rotating output shaft and the first eccentric disc to rotate, affecting the amplitude adjustment accuracy. The brake disc is coupled with the first eccentric disc to limit the circumferential rotation of the first eccentric disc, thereby ensuring the controllable relative position of the first eccentric disc and the second eccentric disc and ensuring the amplitude adjustment accuracy.

As a preferred solution of the present application, the movement of the brake disk is linked to the movement of the drive frame in the present application, which has the advantages of simple control and good reliability.

[0031] Furthermore, in a wide voltage motor for livestock equipment in the present application, a positioning convex portion is provided on the side of the brake disc, a slide groove adapted to the positioning convex portion is provided in the cylinder, and the positioning convex portion is slidably arranged in the slide groove.

[0059] The one-way transmission device is used to drive the second eccentric disk 3 to rotate unidirectionally around the direction a during the reciprocating movement of the driving frame 6. The one-way transmission device includes:

[0060] The annular toothed disc 61 is mounted on the driving frame 6, and the annular toothed disc 61 is arranged on the side of the second eccentric disc 3 near the first eccentric disc 2, and is combined with Fig. 9 As shown, a group of first driving bevel teeth 611 is provided on the annular gear plate 61, and the group of first driving bevel teeth 611 is in a circumferentially spaced array, and a first limiting groove 612 is provided between an adjacent pair of first driving bevel teeth 611;

[0061] Combination Figure 2 A group of second driving helical teeth 21 is shown, the second driving helical teeth 21 are arranged on the first eccentric disk 2 near one end of the second eccentric disk 3, the group of second driving helical teeth 21 is in a circumferentially spaced array, a second limiting groove 22 is provided between an adjacent pair of second driving helical teeth 21, and the first eccentric disk 2 is fixed on the rotating output shaft 11;

[0062] Combination Figure 8 The first transmission bevel teeth 31 shown corresponding to the first driving bevel teeth 611 are arranged on the side of the second eccentric disk 3, and the width of the first transmission bevel teeth 31 is adapted to the first limiting groove 612; and the second transmission bevel teeth 32 corresponding to the second driving bevel teeth 21 are arranged on the second eccentric disk 3 near one end of the first eccentric disk 2, and the width of the second transmission bevel teeth 32 is adapted to the second limiting groove 22;

[0063] The second eccentric disk 3 is sleeved on the rotating output shaft 11 , and one end of the second eccentric disk 3 away from the annular gear disk 61 abuts against the first spring 7 .

[0064] Based on the above device, a wide voltage motor for livestock equipment in this embodiment has the following principle:

[0065] In the reset state, combined with Figure 2 As shown, the first driving bevel teeth 611 are separated from the first transmission bevel teeth 31, and the second transmission bevel teeth 32 are arranged in the second limiting groove 22.

[0066] When adjusting the amplitude, first, the pneumatic cylinder 5 drives the driving frame 6 to move toward the second eccentric disk 3, and then Figure 5 As shown, in this process, the first driving bevel gear 611 conflicts with the first transmission bevel gear 31, so as to push the second eccentric disc 3 to move axially. When the second eccentric disc 3 moves until the second transmission bevel gear 32 moves out of the second limiting groove 22, due to the squeezing force of the first spring 7, the bevel gear surfaces between the first driving bevel gear 611 and the first transmission bevel gear 31 are circumferentially staggered. Figures 3 to 6 As shown, the second eccentric disk 3 rotates around the direction a by a preset angle, and the second transmission bevel gear 32 is staggered with the circumferential position of the corresponding second limit slot 22; then, the pneumatic cylinder 5 moves in the opposite direction to the reset state. During this process, the first spring 7 pushes the second eccentric disk 3 until the second transmission bevel gear 32 conflicts with the second drive bevel gear 21, and the bevel gear tooth surface between the second transmission bevel gear 32 and the second drive bevel gear 21 is staggered circumferentially, so that the second eccentric disk 3 rotates around the direction a until the second transmission bevel gear 32 enters the next second limit slot 22; thus, the second eccentric disk 3 is rotated relative to the first eccentric disk 2, thereby adjusting the amplitude. The pneumatic cylinder 5 reciprocates once, and the amplitude is adjusted by one unit. The pneumatic cylinder 5 can be controlled by the controller to reciprocate continuously for multiple times to adjust the amplitude to the preset requirement. In this embodiment, a separate pneumatic cylinder 5 is used to drive the second eccentric disk 3 to rotate relative to the first eccentric disk 2. Compared with the prior art that uses the motor body 1 to drive and adjust, it has a wider adaptability range for the input voltage of the motor. In addition, the second transmission helical teeth 32 are structurally limited circumferentially by the second limiting groove 22 to achieve torque transmission, which has the advantage of high stability.

The end cover 42 is used to support the front end of the rotating output shaft 11 to ensure the stability of the rotating output shaft 11. In this embodiment, a bearing is provided between the end cover 42 and the rotating output shaft 11.

Specifically, the end cover 42 is provided with a bushing corresponding to the sliding rods 64 one by one, and the sliding rods 64 are inserted into the bushing. The two ends of the sliding rods 64 are respectively connected to a first transmission plate 62 and a second transmission plate 63. The first transmission plate 62 is disc-shaped and is arranged on the axial outer side of the end cover 42. The second transmission plate 63 is arranged On the axial inner side of the end cover 42, the first spring 7 and the rotating output shaft 11 are axially penetrated on the second transmission plate 63, the second eccentric disk 3 is arranged between the second transmission plate 63 and the annular toothed disk 61, and the second transmission plate 63 and the annular toothed disk 61 are connected by a transmission connecting member, and the transmission connecting member is arranged on the radial outer side of the rotation range of the second eccentric disk 3; the cylinder body of the pneumatic cylinder 5 is installed on the outer end of the end cover 42, the sliding rod 64 is arranged on the outer side of the pneumatic cylinder 5, and the first transmission plate 62 is fixed on the telescopic rod of the pneumatic cylinder 5.
