The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0041] When the existing attached vibrator is in operation, the stator winding 200 is energized to generate a driving magnetic field with the rotor assembly, so as to drive the rotor shaft 300 to rotate, and then drive the eccentric assembly to rotate to generate vibration.

[0042] In actual use, under different conditions of concrete pouring, the vibration needs to be adjusted according to different needs. In addition to the eccentric weight and the rotation speed, the setting of the eccentric distance is also particularly critical. The existing attached vibrator only adjusts the vibration frequency by changing the rotation speed through the frequency conversion of the motor. The adjustment of the vibration is limited, the adjustment range is small, and the vibration source is single. The embodiment of the present invention proposes an attached vibrator with adjustable vibration, which adjusts the vibration by adjusting the eccentric distance.

[0043] like Figure 1 As shown, the attached vibrator according to the embodiment of the present invention includes a housing 100 and a vibration system.

[0044] The housing 100 includes a barrel 110 , a first end cover 120 and a second end cover 130 . In some other embodiments, the barrel 110 may extend in the front-to-back or up-to-down direction. This embodiment takes the barrel 110 extending left-to-right as an example.

[0045] The first end cover 120 and the second end cover 130 of the embodiment of the present invention are respectively installed at the left and right ends of the cylinder 110 , so that a vibration cavity 140 is formed inside the housing 100 , and the vibration system is installed in the vibration cavity 140 .

[0046] In order to facilitate inspection and maintenance, the first end cover 120 and the second end cover 130 of this embodiment are both detachably connected to the cylinder 110. In some other embodiments, the cylinder 110 may be an integral structure with the first end cover 120 and the second end cover 130.

[0047] A bracket 150 is provided at the bottom of the cylinder 110 of this embodiment, and the bracket 150 is used for installing and fixing the vibrator.

[0048] like Figure 1 As shown, the vibration system of the embodiment of the present invention includes a stator assembly, a rotor assembly and an eccentric assembly. The stator assembly includes a stator winding 200, and the stator winding 200 is provided with a stator core. The stator winding 200 is fixed to the inner circumferential wall of the cylinder 110, and the rotor assembly includes a rotor shaft 300 and a rotor winding 400. The rotor shaft 300 is extended left and right and arranged in the vibration cavity 140, and the rotor shaft 300 is rotatably installed in the vibration cavity 140. The rotor shaft 300 passes through the stator winding 200 left and right. The left and right ends of the rotor shaft 300 of this embodiment are rotatably connected to the first end cover 120 and the second end cover 130 respectively. In order to improve the rotation stability of the rotor shaft 300, bearing seats are respectively provided on the second end cover 130 and the first end cover 120, and the bearing seats are installed with rotating bearings that rotate with the rotor shaft 300.

[0049] The rotor winding 400 is fixedly sleeved on the outer circumference of the rotor shaft 300 , and the position of the rotor winding 400 corresponds to that of the stator winding 200 . When the stator winding 200 is energized, it can generate a driving magnetic field with the rotor winding 400 to drive the rotor shaft 300 to rotate.

[0050] The eccentric assembly includes at least one eccentric module 500, which is installed on the rotor shaft 300. The eccentric module 500 of this embodiment is staggered with the stator winding 200, so that the installation of the eccentric module 500 is not limited to the stator winding 200, and the magnetic field driving force between the stator winding 200 and the rotor winding 400 is also improved.

[0051] The eccentric module 500 includes an eccentric piece 510 and a radial adjustment mechanism. The eccentric piece 510 is adjustably connected to the outer peripheral wall of the rotor shaft 300 in the radial direction through the radial adjustment mechanism.

[0052] When in use, the stator winding 200 is energized to generate a driving magnetic field with the rotor winding 400 to drive the rotor shaft 300 to rotate, and the rotor shaft 300 drives the eccentric piece 510 to generate vibration. When the vibration needs to be adjusted, the axial position of the eccentric piece 510 along the rotor shaft 300 is adjusted by the radial adjustment mechanism to adjust the eccentricity of the eccentric piece 510. Under the existing speed of the motor through frequency conversion, the present technology also adjusts the exciting force by adjusting the radial position of the eccentric piece 510 to meet different needs.

[0053] like Figure 1 and Figure 4 As shown, the radial adjustment mechanism of the embodiment of the present invention includes a screwdriver 520 and a connecting tube 530. The connecting tube 530 is fixed to the outer periphery of the rotor shaft 300, and the connecting tube 530 is extended radially along the rotor shaft 300. The outer periphery of the rotor shaft 300 of this embodiment is sleeved with a connecting sleeve 540, and the connecting sleeve 540 is connected to the rotor shaft 300 by a key to achieve axial locking. The inner end of the connecting tube 530 is fixedly connected to the connecting sleeve 540.

[0054] like Figure 2 As shown, the eccentric member 510 of this embodiment is provided with a connecting screw 550 extending radially along the rotor shaft 300, and the connecting screw 550 is threadedly connected to the connecting cylinder 530, and a rotating portion 511 is provided at the outer end of the eccentric member 510 radially away from the rotor shaft 300, and the rotating portion 511 is coaxially arranged with the connecting screw 550.

[0055] like Figure 2 As shown, a manipulation hole 160 is provided on the outer peripheral wall of the housing 100. In this embodiment, a manipulation hole 160 is provided on the outer peripheral wall of the cylinder 110. The manipulation hole 160 is provided corresponding to the rotating part 511. It can be understood that the manipulation hole 160 is provided on the trajectory of the rotating part 511 following the rotation of the rotor shaft 300. Figure 5 As shown, the screwdriver 520 is provided with a screwdriver head 521 that matches and engages with the rotating portion 511. When the radial position of the eccentric member 510 needs to be adjusted, the rotor shaft 300 rotates to a position corresponding to the rotating portion 511 and the operating hole 160, and then the screwdriver head 521 extends into the operating hole 160 from the outside to the inside. The screwdriver head 521 engages with the rotating portion 511, and the eccentric member 510 is driven to rotate by the screwdriver 520 to realize the rotation of the connecting screw 550 in the connecting cylinder 530 to adjust the radial position of the eccentric member 510.

[0056] like Figure 2 As shown, the operating hole 160 of the embodiment of the present invention is detachably covered with a cover 161. After adjustment, the cover 161 blocks the operating hole 160, so that the vibration cavity 140 remains closed, thereby achieving a dust-proof effect.

[0057] In the embodiment of the present invention, the radial position of the eccentric member 510 is adjusted by means of a screwdriver 520 , and the housing 100 can be closed after the adjustment, so the operation is convenient and simple.

[0058] like Figure 2 and Figure 5 As shown, the embodiment of the present invention takes into account that during the operation of the vibrator, relative rotation may occur between the connecting screw 550 and the connecting cylinder 530, which may cause the eccentric piece 510 to malfunction or even be thrown out. The radial adjustment mechanism of the embodiment of the present invention also includes a locking structure 560. When the vibrator is operating normally, the locking structure 560 is used to lock the relative rotation between the connecting screw 550 and the connecting cylinder 530, thereby avoiding relative rotation between the connecting screw 550 and the connecting cylinder 530. When the vibration needs to be adjusted, the lock between the connecting screw 550 and the connecting cylinder 530 is released.

[0059] like Figure 2 and Figure 5 As shown, the outer end of the connecting tube 530 away from the rotor shaft 300 of the embodiment of the present invention is provided with an adjusting screw hole 531, and the connecting screw 550 is threadedly connected to the adjusting screw hole 531 to achieve radial adjustment, and an annular locking step 532 is provided at the bottom of the adjusting screw hole 531, the locking step 532 is arranged on the inner circumferential wall of the connecting tube 530 and is arranged downward, and a plurality of first locking portions 533 are evenly distributed in an annular manner on the bottom surface of the locking step 532, and an annular abutting shoulder 551 is provided on the outer periphery of the connecting screw 550, and the abutting shoulder 551 is located in the connecting tube 530. It can be understood that the abutting shoulder 551 is arranged on the outer periphery of the inner end of the connecting screw 550, and the locking step 532 and the abutting shoulder 551 are arranged opposite to each other up and down.

[0060] like Figure 2 and Figure 5 As shown, the locking structure 560 includes a locking ring 561 and an elastic locking module. The locking ring 561 is axially slidably sleeved on the outer periphery of the connecting screw 550. The locking ring 561 is located between the locking step 532 and the abutting shoulder 551, and the end face of the locking ring 561 facing the locking step 532 is annularly evenly distributed with a plurality of second locking portions 5611.

[0061] The elastic locking module is configured to drive the locking ring 561 to move axially so that the second locking portion 5611 is engaged with the first locking portion 533, thereby locking the relative rotation between the connecting screw 550 and the connecting cylinder 530, so that the second locking portion 5611 is separated from the first locking portion 533 and the relative rotation between the connecting screw 550 and the connecting cylinder 530 is loosened. It can be understood that when the eccentricity of the eccentric member 510 needs to be adjusted, the elastic locking module drives the locking ring 561 to move downward and away from the locking step 532, so that the second locking portion 5611 and the first locking portion 533 are engaged. The fixed part 533 is separated, and the connecting screw 550 can be controlled to rotate relative to the connecting tube 530. After the eccentricity of the eccentric piece 510 is adjusted, the elastic locking module drives the locking ring 561 to move upward, close to the locking step 532, so that the second locking part 5611 is engaged with the first locking part 533. At this time, since the locking ring 561 and the connecting screw 550 can only move relative to each other in the axial direction and are relatively fixed in the circumferential direction, the connecting screw 550 and the connecting tube 530 are locked in the circumferential direction under the locking of the locking ring 561 and the locking step 532.

[0062] like Figure 2 and Figure 5 As shown, the second locking portion 5611 of this embodiment is a boss structure, and the first locking portion 533 is a groove structure. In some other embodiments, the second locking portion 5611 is a groove structure, and the first locking portion 533 is a boss structure.

[0063] Furthermore, for the convenience of operation, the embodiment of the present invention combines the moving operation of the locking ring 561 and the rotating operation of the eccentric member 510 together, specifically: Figure 2 , Figure 3 and Figure 5 As shown, the connecting screw 550 of the embodiment of the present invention is provided with a guide channel 552 and a guide groove 553, and the guide groove 553 is provided at the lower part of the connecting screw 550. In the axial perspective, the guide groove 553 penetrates the connecting screw 550 in the radial direction and is in a straight line shape. In other embodiments, it may be in a cross shape. In the side view, the guide groove 553 extends in the axial direction.

[0064] The guide channel 552 is arranged along the axial direction of the connecting screw 550. It can be understood that the upper end of the guide channel 552 passes through the rotating part 511, and the lower end of the guide channel 552 passes through the guide groove 553 and extends downward to the lower end of the connecting screw 550.

[0065] like Figure 2 , Figure 3 and Figure 5As shown, the inner circumference of the locking ring 561 is connected with a connecting cross bar 5612, which passes through the guide groove 553 laterally and slides along the axial direction of the connecting screw 550. The two ends of the connecting cross bar 5612 are respectively fixedly connected to the inner circumference of the locking ring 561. Through the sliding cooperation between the connecting cross bar 5612 and the guide groove 553, the axial sliding of the locking ring 561 along the axial direction of the connecting screw 550 and the circumferential locking are realized.

[0066] The elastic locking module of the embodiment of the present invention includes an elastic member 562 and a push rod 563. The push rod 563 is slidably arranged in the guide channel 552 up and down. The lower end of the push rod 563 abuts against the connecting cross bar 5612, and the elastic member 562 acts between the locking ring 561 and the abutting shoulder 551 to push the locking ring 561 close to the locking step 532 and make the upper end of the push rod 563 extend from the rotating part 511. The screwdriver bit 521 is configured to push the push rod 563 downward when it is matched and engaged with the rotating part 511.

[0067] It is understandable that if Figure 5 As shown, when adjusting the eccentricity of the eccentric member 510, the screwdriver bit 521 is inserted into the rotating portion 511 downward, and the push rod 563 is pushed downward to drive the locking ring 561 to move downward, and the elastic member 562 is compressed, so that the second locking portion 5611 is separated from the first locking portion 533. Then, the screwdriver 520 is rotated to drive the connecting screw 550 to rotate, so as to drive the eccentric member 510 to move radially along the rotor shaft 300; Figure 2 After adjusting the eccentricity of the eccentric member 510, the screwdriver bit 521 is pulled out. At this time, under the action of the resetting elastic force of the elastic member 562, the locking ring 561 moves upward, so that the second locking portion 5611 is engaged with the first locking portion 533, thereby realizing the locking between the connecting screw 550 and the connecting tube 530. Therefore, the present invention does not need to add an additional operation step to drive the locking ring 561 to move, and can be done by operating the screwdriver 520.

[0068] The elastic member 562 of the embodiment of the present invention is a spring, which is sleeved on the outer circumference of the connecting screw 550 to achieve positioning installation. The upper end of the spring abuts against the locking ring 561 , and the lower end of the spring abuts against the abutting shoulder 551 .

[0069] According to the transmission principle, when the eccentricity of the eccentric member 510 is reduced, the upper end of the push rod 563 will move upward relative to the eccentric member 510. In order to provide a sufficient upward position for the push rod 563 without affecting the normal operation of the eccentric member 510, Figure 2 and Figure 5As shown, the rotating portion 511 of the embodiment of the present invention is configured as a countersunk hole structure, and the countersunk hole structure extends downward into the connecting screw 550, and the depth of the countersunk hole structure is greater than the radial adjustment stroke of the eccentric member 510 along the rotor shaft 300. It can be understood that when the eccentric member 510 is located at the maximum eccentricity position, the upper end of the push rod 563 at this time will extend into the countersunk hole structure to ensure that the screwdriver 521 can push the push rod 563, and when the eccentric member 510 moves radially inward along the rotor shaft 300 and reduces the eccentricity, the push rod 563 at this time moves upward relative to the eccentric member 510, limiting the depth of the countersunk hole structure to be greater than the radial adjustment stroke of the eccentric member 510, and limiting the upper end of the push rod 563 to be always located in the countersunk hole structure, thereby preventing the upper end of the push rod 563 from being exposed and contacting the inner wall of the casing 100, affecting the normal operation of the vibrator, and also ensuring that the screwdriver 521 can quickly and accurately extend into the countersunk hole structure and then push the push rod 563.

[0070] The cross section of the rotating portion 511 of the embodiment of the present invention is cross-shaped, and the bit 521 is also cross-shaped.

[0071] like Figure 2 As shown, a limiting shoulder 5631 is provided on the periphery of the push rod 563 of the embodiment of the present invention, and a first limiting step 5521 is provided on the upper portion of the guide channel 552. The first limiting step 5521 is in upper and lower contact with the limiting shoulder 5631 to limit the upper limit position of the push rod 563 relative to the guide channel 552. The upper limit position of the push rod 563 is limited to prevent the upper end of the push rod 563 from extending out of the eccentric member 510. This also limits the lower limit position of the connecting screw 550 relative to the connecting cylinder 530, that is, limits the minimum eccentric distance of the eccentric member 510.

[0072] In addition, a second limiting step 534 is provided on the inner periphery of the connecting tube 530, and the second limiting step 534 is in upper and lower abutment with the abutment shoulder 551 to limit the upper limit position of the connecting screw 550 relative to the connecting tube 530, that is, to limit the maximum eccentricity of the eccentric piece 510 to prevent the eccentric piece 510 from touching the inner wall of the casing 100.

[0073] In some embodiments, the outer wall of the abutting shoulder 551 is provided with an external thread, and the inner wall of the connecting tube 530 is provided with an internal thread, so that the outer periphery of the abutting shoulder 551 cooperates with the inner thread of the connecting tube 530 to form a two-point support connection in the upper and lower parts, thereby improving the structural strength and stability of the eccentric member 510.

[0074] When adjusting the vibration, in order to quickly make the rotating part 511 correspond to the operating hole 160, as shown in FIG. Figure 1 and Figure 4As shown, the attached vibrator of the embodiment of the present invention also includes a stopping mechanism 600, which includes a stopping plate 610 and a stopping structure. The stopping plate 610 is fixedly sleeved on the rotor shaft 300 and is located outside the casing 100. One end of the rotor shaft 300 extends out of the casing 100, and in order to facilitate the adjustment of the rotation position of the rotor shaft 300, a hexagonal countersunk hole 310 is coaxially arranged at the protruding end of the rotor shaft 300, so that the user can drive the rotor shaft 300 to rotate through the hexagonal head so that the rotating part 511 corresponds to the operating hole 160.
