[0002] When pouring components with concrete mixed by a concrete mixer, it is necessary to remove the bubbles and tamp the concrete to make it densely combined and eliminate the honeycombed surface of the concrete, so as to improve its strength and ensure the quality of the concrete components.

[0003] However, the existing hydraulic concrete vibrator has a limitation when in use, that is, the vibration amplitude of the vibrator cannot be adjusted. Since the vibration amplitude cannot be adjusted, this may make it difficult to achieve the best effect when processing concrete of different types or volumes. In some specific cases, it is necessary to adjust the vibration amplitude according to the concrete formula or construction environment to ensure that the density and uniformity of the concrete meet the requirements. Therefore, the lack of vibration amplitude adjustment function may limit the flexibility and applicability of the concrete vibrator in some specific application scenarios. Utility Model Content

A rotating rod 112 is movably embedded in the top of the rotating disk 108, and a crank 113 is fixedly installed on the top of the rotating rod 112. A screw 110 is fixedly installed on the bottom of the rotating rod 112. The bottom outer surface of the screw 110 is movably embedded in the bottom side of the inner wall of the second slide groove 109, and the outer surface of the screw 110 is movably sleeved with a second slider 111. The outer surface of the second slider 111 is slidably connected to the inner surface of the second slide groove 109, and an eccentric wheel 114 is fixedly installed on the right side of the second slider 111. Hinges 2 are fixedly installed on both sides of the top of the vibration plate 1.

[0029] In this embodiment, the personnel first places the vibration plate 1 on the concrete, and starts the hydraulic motor 107 through the driving system of the hydraulic motor 107 on the support 106, so that when it is running, it drives the eccentric wheel 114 to move in a circle through the rotating disk 108. When the eccentric wheel 114 rotates to the bottom, it pushes the pressing plate 103 downward, driving the first sliding block 105 to slide inside the first sliding groove 104 opened on the partition 101, and driving the reset spring 102 to contract at the same time. When the eccentric wheel 114 rotates to the top, the reset spring 102 is reset, thereby driving the pressing plate 103 to rise, and the reset spring 102 is reciprocatedly contracted and reset through the circular rotation of the eccentric wheel 114, thereby driving the vibration plate 1 When the vibration intensity of the device needs to be adjusted, the crank handle 113 can be turned to transmit it to the screw 110 through the rotating rod 112, so that when the screw 110 rotates, it drives the second slider 111 to slide downward through the second slide groove 109, thereby driving the eccentric wheel 114 to move downward synchronously, so that when the eccentric wheel 114 rotates to the bottom, the reset spring 102 can be further contracted, thereby adjusting the vibration amplitude of the vibration plate 1, and through the structures such as the eccentric wheel 114 and the pressing plate 103, the device can change the movement trajectory of the eccentric wheel 114, thereby adjusting the contraction degree of the reset spring 102, and finally affecting the vibration amplitude of the vibration plate 1, thereby making the equipment more suitable for different construction environments and requirements, thereby improving the applicability of the device.

[0030] Embodiment 2, as Figure 1-4 As shown, the first support column 201 is movably connected at the inner center of the two hinges 2, and the second support column 202 is movably embedded inside the two first support columns 201. The front sides of the two first support columns 201 are threadedly connected with bolts 203, and the tops of the two second support columns 202 are fixedly installed with push handles 204, and the center of the outer surface of the push handles 204 is fixedly sleeved with an anti-slip pad 205.

[0031] In this embodiment, the personnel can first reverse the bolt 203 to make one end of it move away from the second support column 202, and pull the push handle 204 upward to make the second support column 202 slide upward inside the first support column 201, and then adjust the height of the push handle 204. When the height adjustment is completed, the bolt 203 can be turned forward to make one end of it fit the second support column 202 again to fix it, and the personnel can press the push handle 204 downward to make the first support column 201 flip downward through the hinge 2, and then adjust the angle of the push handle 204. After the angle and height adjustment of the equipment are completed, the personnel can hold the anti-slip pad 205 to push the equipment to vibrate the concrete. Through the structures such as the first support column 201 and the hinge 2, the device can conveniently adjust the height and angle of the concrete vibrating equipment, thereby increasing the flexibility and convenience of operation of the operator at the construction site.

[0032] Working principle: When in use, the personnel first place the vibration plate 1 on the concrete, and start the hydraulic motor 107 through the driving system of the hydraulic motor 107 on the support 106, so that when it is running, it drives the eccentric wheel 114 to move in a circle through the rotating disk 108. When the eccentric wheel 114 rotates to the bottom, it pushes the pressing plate 103 downward, driving the first sliding block 105 to slide inside the first sliding groove 104 opened on the partition 101, and driving the reset spring 102 to contract at the same time. When the eccentric wheel 114 rotates to the top, the reset spring 102 is reset, thereby driving the pressing plate 103 to rise, and the reset spring 102 is reciprocatedly contracted and reset through the circular rotation of the eccentric wheel 114, thereby driving the vibration plate 103 to rise. The plate 1 vibrates. When the vibration intensity of the device needs to be adjusted, the crank handle 113 can be turned to transmit it to the screw 110 through the rotating rod 112, so that when the screw 110 rotates, it drives the second slider 111 to slide downward through the second slide groove 109, and then drives the eccentric wheel 114 to move downward synchronously, so that when the eccentric wheel 114 rotates to the bottom, the reset spring 102 can be further contracted, thereby adjusting the vibration amplitude of the vibration plate 1, and through the structures such as the eccentric wheel 114 and the pressing plate 103, the device can change the movement trajectory of the eccentric wheel 114, thereby adjusting the contraction degree of the reset spring 102, and finally affecting the vibration amplitude of the vibration plate 1, so that the equipment is more suitable for different construction environments and requirements, thereby improving the applicability of the device. When in use, the personnel can first reverse the bolt 203 to make one end of it move away from the second support column 202, and pull the push handle 204 upward to make the second support column 202 slide upward inside the first support column 201, and then adjust the height of the push handle 204. When the height adjustment is completed, the bolt 203 can be turned forward to make one end of it fit the second support column 202 again to fix it, and the personnel can press the push handle 204 downward to make the first support column 201 flip downward through the hinge 2, and then adjust the angle of the push handle 204. After the angle and height adjustment of the equipment are completed, the personnel can hold the anti-slip pad 205 and then push the equipment to vibrate the concrete. Through the structures such as the first support column 201 and the hinge 2, the device can conveniently adjust the height and angle of the concrete vibrating equipment, thereby increasing the flexibility and convenience of operation of the operator at the construction site.
