Description

Technical Field

[0001] The utility model belongs to the technical field of road construction, and particularly relates to a resonance crusher. Background Art

[0002] Roads typically consist of a pavement, base layer, subbase layer, cushion layer, and subgrade. Each layer has specific material and thickness requirements to ensure the road's overall stability and durability. Crushing cement pavement is a crucial step in road repair and reconstruction, requiring the use of a resonance crusher.

[0003] Common crushers are supported by the crusher frame structure and wheels. The local vibration process of the crusher lacks a supporting structure. When encountering poor road conditions, the crusher parts cannot be adjusted and supported according to the road conditions. Not only are the usage scenarios limited, but the stability is also insufficient. For this reason, we propose a cement pavement resonance crusher. Utility Model Content

[0004] The purpose of the utility model is to provide a resonance crusher, which can be flexibly adjusted according to the flatness of the road surface under the mutual cooperation of the supporting mechanism, and stably support the crusher parts, which helps to improve the overall performance of the resonance crusher.

[0009] Preferably, a movable groove is provided on the front side of the supporting leg, and the limiting member is arranged inside the movable groove.

[0010] Preferably, the surfaces of the round rod and the rotating rod are both sleeved with circular rings, and the circular rings are respectively located on both sides of the gear and the output wheel of the gear plate.

[0011] Preferably, a blocking bar is fixedly connected to the rear side of the inner wall of the support leg, and the gear rod is located on the inner side of the blocking bar.

[0012] The technical effects achieved by this utility model are:

[0013] In the utility model, through the coordinated use of the support mechanism, when the staff is using the crusher body, they can first spread the support legs and make them perpendicular to the ground, and then turn the handle clockwise. The clockwise rotation of the handle can simultaneously drive the rotating rod to rotate, and the rotation of the rotating rod can drive the output wheel to rotate clockwise. The rotation of the output wheel can drive the meshing toothed disc to rotate counterclockwise, and the rotation of the gear will simultaneously drive the round rod and the gear to rotate counterclockwise. The rotation of the gear can also drive the meshing toothed rod and the top plate to move upward slowly and steadily. On the contrary, the support legs will move downward and make the support legs contact the ground. Then, the handle is continuously rotated to make the toothed rod drive the top plate to move continuously upward, and the crusher body will be stably supported. When the support mechanism is running, the support height of the support mechanism can be flexibly adjusted according to the flatness of the ground.

[0014] When the support mechanism is in operation, the handle drives the rotating rod to rotate and drives the chainring to rotate clockwise at the same time. When the chainring rotates, the limit piece will be engaged with the teeth of the chainring along the direction of rotation, and the limit piece will be pushed upward under the elastic force of the compression spring to stably engage with the teeth of the chainring, thereby self-locking the chainring and self-locking the support leg mechanism to prevent the support mechanism from falling due to excessive force. When the crusher body is no longer needed to be supported, the staff can press the limit piece downward to move the front end of the limit piece downward and tilt the rear end upward, so that the limit piece no longer limits the chainring, and then press the tooth rod under the weight of the crusher body and retract the tooth rod into the inside of the support leg.

[0015] In the utility model, after the support legs are retracted, the staff can pull the limit rod outward, and the outward movement of the limit rod can squeeze the telescopic spring. Then the support legs can be rotated backward about ninety degrees, and then the hand can be separated from the limit rod. The limit rod can be pushed inward under the action of the telescopic spring and connected with the limit hole. The support legs can be retracted to the bottom of the crusher body, avoiding the support legs from drooping and bumping when the crushing vehicle is moved. BRIEF DESCRIPTION OF THE DRAWINGS

The top plate 201 is hingedly connected to the bottom of the crusher body 102, the legs 202 are arranged at the bottom of the top plate 201, and the round rod 203 is fixedly connected to the bottom of the crusher body 102. Connected to the inside of the leg 202, the gear 204 is sleeved on the surface of the round rod 203, the toothed disc 205 is sleeved on the surface of the round rod 203 and is located on one side of the gear 204, the gear rod 206 is meshed and connected to the rear side of the gear 204, the top of the gear rod 206 is fixedly connected to the top plate 201, one end of the rotating rod 207 is connected to the inner wall of the leg 202 through a bearing, and the other end of the rotating rod 207 passes through the outside of the leg 202, the output wheel 208 is sleeved on the surface of the rotating rod 207, and the output wheel 208 is meshed and connected to the top of the toothed disc 205. The handle 209 is fixedly connected to one end of the rotating rod 207. Through the cooperation of the supporting mechanism, when the staff uses the crusher body 102, they can first open the support legs 202 and make them perpendicular to the ground, and then turn the handle 209 clockwise. The clockwise rotation of the handle 209 can simultaneously drive the rotating rod 207 to rotate. The rotation of the rotating rod 207 can drive the output wheel 208 to rotate clockwise. The rotation of the output wheel 208 can drive the meshing toothed disc 205 to rotate counterclockwise. The rotation of the gear 204 will also drive the round rod 203 and the gear 204. 04 rotates counterclockwise, and the gear 204 rotates and can drive the meshing connected tooth rod 206 and the top plate 201 to move upward slowly and steadily. On the contrary, the support leg 202 will move downward and make the support leg 202 contact with the ground. Then continue to turn the handle 209, which can make the tooth rod 206 drive the top plate 201 to continue to move upward, and will provide stable support for the crusher body 102. When operating the support mechanism, the support height of the support mechanism can be flexibly adjusted according to the flatness of the ground, thereby improving the crushing effect and reducing the need for repeated operations.

[0025] like Figure 3-4As shown, a self-locking mechanism is provided inside the support leg 202, which includes a chainring 301, a limiting member 302, a pad 303 and a spring. The chainring 301 is sleeved on the surface of the rotating rod 207, and the limiting member 302 is connected to the inside of the support leg 202 through a rotating shaft. One end of the limiting member 302 is clamped in the teeth of the chainring 301, and the other end of the limiting member 302 passes through the front side of the support leg 202. The pad 303 is fixedly connected to the front side of the support leg 202, one end of the compression spring 304 is fixedly connected to the top of the pad 303, and the other end of the compression spring 304 is fixedly connected to the bottom of the limiting member 302. When the support mechanism is operated, the handle 209 drives the rotating rod 207 to rotate and can drive the chainring 301 to rotate clockwise at the same time. When the chainring 301 rotates, the limiting member 302 When the cam 302 is in the unlock state, the cam 302 is in the unlock state, and the cam 302 is locked in the unlock state, so that the cam 302 is locked in the unlock state.

[0026] like Figure 5 As shown, a movable groove 5 is opened on the front side of the support leg 202, and the limiting member 302 is arranged inside the movable groove 5. When the staff presses the limiting member 302, the limiting member 302 can be flexibly moved inside the movable groove 5, so that the limiting member 302 has sufficient movable space to prevent the limiting member 302 from colliding with the support leg 202.

[0027] like Figure 1-2As shown, both sides of the bottom of the crusher body 102 are fixedly connected with vertical plates 401, and a limit hole 402 is provided on the outer side of the support leg 202. A limit rod 403 is provided on the outer side of the vertical plate 401. The other end of the limit rod 403 passes through the vertical plate 401 and extends to the inside of the limit hole 402. A telescopic spring 404 is sleeved on the surface of the limit rod 403. One end of the telescopic spring 404 is fixedly connected to the inner side of the vertical plate 401, and the other end of the telescopic spring 404 is fixedly connected to the limit rod 403. 02 After retracting, the staff can pull the limit rod 403 outward. The outward movement of the limit rod 403 can squeeze the telescopic spring 404, and then the support leg 202 can be rotated backward about ninety degrees. Then, the hand can be separated from the limit rod 403, and the limit rod 403 can be pushed inward under the action of the telescopic spring 404, and connected with the limit hole 402, so that the support leg 202 can be retracted to the bottom of the crusher body 102, avoiding the support leg 202 from drooping and bumping when the crushing vehicle 101 is moved.

[0028] like Figure 3-4 As shown, the surfaces of the round rod 203 and the rotating rod 207 are both provided with a circular ring 6, which is respectively located on both sides of the gear 204 of the toothed disc 205 and the output wheel 208 to prevent the round rod 203 and the rotating rod 207 from being worn and displaced from the toothed disc 205 and the gear 204 after a long period of rotation, thereby providing auxiliary limiting for them so that they can cooperate with each other.

[0029] like Figure 3 As shown, a baffle 7 is fixedly connected to the rear side of the inner wall of the support leg 202, and the gear rod 206 is located on the inner side of the baffle 7. When the gear rod 206 moves up and down, it can move vertically on the inner side thereof with the assistance of the baffle 7, so as to prevent the gear rod 206 from being offset during movement and being disconnected from the gear 204, which would affect the normal operation of the support mechanism.

[0030] The working principle of the present invention is as follows: when the staff is using the crusher body 102, they can first open the support legs 202 and make them perpendicular to the ground, and then rotate the handle 209 clockwise. The clockwise rotation of the handle 209 can simultaneously drive the rotating rod 207 to rotate, and the rotation of the rotating rod 207 can drive the output wheel 208 to rotate clockwise. The rotation of the output wheel 208 can drive the meshing toothed disc 205 to rotate counterclockwise, and the rotation of the gear 204 will simultaneously drive the round rod 203 and the gear 204 to rotate counterclockwise. The rotation of the gear 204 can simultaneously drive the meshing toothed rod 206 and the top plate 201 to move upward slowly and steadily. On the contrary, the support legs 202 will move downward and make the support legs 202 contact the ground. Then continue to rotate the handle 209, so that the toothed rod 206 can drive the top plate 201 to move continuously upward, and the crusher body 102 will be stably supported. When the support mechanism is in operation, it can be adjusted according to the ground When the support mechanism is in operation, the handle 209 drives the rotating rod 207 to rotate and drives the chain disc 301 to rotate clockwise. When the chain disc 301 rotates, the limit member 302 is engaged with the teeth of the chain disc 301 along the rotation direction and pushed upward by the elastic force of the compression spring 304 to stably engage with the teeth of the chain disc 301, thereby self-locking the chain disc 301 and self-locking the support leg 202 mechanism to prevent the support mechanism from falling due to excessive force. When the crusher body 102 is no longer needed to support the crusher body 102, the staff can press the limit member 302 downward to move the front end of the limit member 302 downward and tilt the rear end upward, so that the limit member 302 no longer limits the chain disc 301, and then presses the tooth rod 206 under the weight of the crusher body 102 and retracts the tooth rod 206 into the inside of the support leg 202.

[0031] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
