[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 - 3 , in the embodiment of the present utility model, an eccentric vibrator of a concrete brick making machine includes a base 1, a vibrator 2 is installed at the top end of the base 1, a vibrating plate 3 is installed at the top end of the vibrator 2 through bolts, and a limiting mechanism 4 provided at the output end of the vibrator 2;

[0031] The limiting mechanism 4 includes a limiting unit and a transmission unit;

[0032] The limiting unit is used to provide limitation for the connection between the eccentric wheel 401 and the vibrator 2;

[0033] The transmission unit is used to provide guidance for the movement of the limiting unit;

[0034] The transmission unit includes an eccentric wheel 401, a pressing rod 402, a spring 403, a limiting block 404, a guiding block 405, and a guiding groove 406;

[0035] The eccentric wheel 401 is sleeved on the outer wall of the vibrator 2, and the eccentric wheel 401 is used to transmit the rotational force from the vibrator 2;

[0036] The pressing rod 402 is axially slidably installed on the inner wall of the output end shaft of the vibrator 2 and extends to the outer wall of the vibrator 2, and the pressing rod 402 is used to drive the limiting block 404 to move synchronously;

[0037] Both ends of the spring 403 are respectively clamped on the inner wall of the shaft of the vibrator 2 and the outer wall of the pressing rod 402, and the spring 403 is used to always provide an elastic thrust in one direction for the pressing rod 402;

[0038] The limiting block 404 is vertically slidably installed on the inner wall of the pressing rod 402 and extends to the outer wall of the top end of the pressing rod 402. The limiting block 404 is used to transmit the rotational force from the vibrator 2 to the eccentric wheel 401;

[0039] The guiding block 405 is fixed on the outer wall of the limiting block 404 and extends to the inner side of the guiding groove 406. The guiding block 405 is used to drive the guiding groove 406 to move synchronously;

[0040] The guiding groove 406 is formed on the inner wall of the shaft rod of the vibrator 2. The guiding groove 406 is used to provide guidance for the vertical movement of the guiding block 405 and the limiting block 404;

[0041] The limiting unit includes a limiting groove 407 and a movable groove 408;

[0042] The limiting groove 407 is formed on the inner wall of the eccentric wheel 401. The limiting groove 407 is used to cooperate with the limiting block 404 to limit the rotation of the eccentric wheel 401;

[0043] The movable groove 408 is formed on the inner wall of the eccentric wheel 401 and is located on one side of the limiting groove 407. The movable groove 408 is used to provide a moving space for the movement of the limiting block 404.

[0044] In this embodiment: When it is necessary to adjust the angle of the eccentric wheel 401, a squeezing force can be applied to the pressing rod 402. The stressed pressing rod 402 will axially move along the inner wall of the output end shaft rod of the vibrator 2, and a squeezing force is applied to the spring 403. The moving pressing rod 402 synchronously drives the limiting block 404 to move, so that the guiding block 405 fixed on the outer wall of the limiting block 404 will move along the inner side of the guiding groove 406. Since the outer wall of the guiding groove 406 is integrally inclined, then the guiding block 405 will drive the limiting block 404 to enter the inside of the limiting block 404 along the track of the guiding groove 406, and at this time the limiting block 404 will also gradually move from the inside of the limiting groove 407 to the inside of the movable groove 408, releasing the rotational limit of the eccentric wheel 401. At this time, a rotational force can be applied to the eccentric wheel 401 to adjust the angles of the two eccentric wheels 401 to be the same. The operation is convenient and the work efficiency is further improved.

[0045] Please refer specifically to Figures 1 - 3 , the number of the limiting grooves 407 is set to be multiple. The multiple limiting grooves 407 are evenly distributed on the inner wall of the eccentric wheel 401. The inner wall of the limiting groove 407 matches the outer wall of the limiting block 404. The multiple limiting grooves 407 are annularly distributed and the axis is the same as the axis of the vibrator 2. The inner wall of the guiding groove 406 matches the outer wall of the guiding block 405. The outer wall of the guiding groove 406 is integrally inclined. A chute for the axial movement of the pressing rod 402 is formed on the inner wall of the output end shaft rod of the vibrator 2. The outer wall of the pressing rod 402 is integrally in a "T" - shaped structure.

[0046] In this embodiment: With this structure, under the action of the "T" shape of the pressing rod 402, the moving distance of the pressing rod 402 can be limited. Through a plurality of limiting grooves 407, after the eccentric wheel 401 rotates to other angles, the limiting block 404 can enter into a corresponding limiting groove 407 again.

[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
