DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figure 1-5 As shown, a concrete vibrating and compacting device according to an embodiment of the present invention comprises a portable motor 2 and a flexible shaft connector 3 installed at the output end of the portable motor 2, a vibrating rod 1 is installed at one end of the flexible shaft connector 3, a rotating shaft 12 is rotatably installed inside the vibrating rod 1, an eccentric shaft 121 is installed outside the rotating shaft 12, bearings 13 are installed at the upper and lower ends of the rotating shaft 12, the bearing 13 is installed inside the vibrating rod 1, an oil delivery component 5 is fixedly installed inside the vibrating rod 1, and the oil delivery component 5 is installed outside the rotating shaft 12, the oil delivery component 5 is located at the lower side of the corresponding bearing 13, lubricating oil is stored inside the oil delivery component 5, an oil groove 51 is opened on the upper side of the oil delivery component 5, and the oil exposed at the oil groove 51 is used to lubricate the bearing 13;

[0036] The outer side of the flexible shaft connector 3 is wrapped with a layer of elastic rubber pipe, the output end of the portable motor 2 is connected to the rotating shaft 12 through the flexible shaft connector 3, and the lower end of the vibrating rod 1 is installed with a tip block 11.

[0037] Specifically, when it is necessary to vibrate and compact the concrete, the portable motor 2 is used for electric drive. With the cooperation of the flexible shaft connector 3, the rotating shaft 12 and the eccentric shaft 121 rotate inside the vibrating rod 1. When the eccentric shaft 121 rotates as an eccentric structure, it will drive the vibrating rod 1 to vibrate. The vibrating rod 1 is placed inside the concrete for vibration. The vibrating rod 1 vibrates at different positions of the concrete. At this time, the bubbles inside the concrete will float to the surface, and then the bubbles will be removed to achieve the purpose of compacting the concrete. An oil delivery component 5 is provided inside the vibrating rod 1. Lubricating oil is stored inside the oil delivery component 5. When the rotating shaft 12 and the eccentric shaft 121 rotate for too long, the bearing 13 installed on the outside of the rotating shaft 12 will be damaged. At this time, the lubricating oil inside the oil delivery component 5 can be squeezed out, that is, it appears inside the oil tank 51. The lubricating oil will contact the bearing 13 to lubricate it, ensuring that the rotating shaft 12 and the eccentric shaft 121 can rotate for a longer time, that is, the vibrating rod 1 can vibrate the concrete for a longer time.

[0038] like Figure 2 and Figure 4 As shown, a shaft mounting groove 14 and a vibration groove 15 are provided inside the vibrating rod 1, and the shaft mounting groove 14 and the vibration groove 15 are connected, and two bearings 13 are installed at the upper and lower ends inside the shaft mounting groove 14, and the oil delivery component 5 is installed at the inner upper end of the vibration groove 15, and the eccentric shaft 121 is located inside the vibration groove 15, and a water pump component 4 is fixedly installed on the outer side of the flexible shaft connector 3, and a plurality of water delivery hoses 41 are fixedly installed on the lower end of the water pump component 4, and the plurality of water delivery hoses 41 are fixedly installed on the outer side of the flexible shaft connector 3, and one end of the plurality of water delivery hoses 41 passes through the vibrating rod 1 and extends to the interior of the oil delivery component 5.

[0039] Specifically, when the eccentric shaft 121 rotates with the rotating shaft 12, the eccentric shaft 121 is always in the vibration groove 15 and will not collide with the vibration groove 15. The water pump assembly 4 stores water and is equipped with a micro water pump. The micro water pump is operated by an external switch to transport water to the interior of the oil delivery assembly 5 through multiple water hoses 41. The water hoses 41 are components made of elastic rubber material and can bend with the flexible shaft connector 3 without affecting the operation of the flexible shaft connector 3 itself.

[0040] like Figure 5 As shown, the bearing 13 includes an inner shaft 131 connected to the outer side of the rotating shaft 12 and an outer shaft 132 connected to the inner wall of the shaft mounting groove 14. The distance between the inner shaft 131 and the outer shaft 132 is directly above the oil groove 51. The oil delivery component 5 is an annular structure, and the oil groove 51 is an annular groove.

[0041] Specifically, when the rotating shaft 12 rotates, the inner shaft 131 rotates along with the rotating shaft 12, and the outer shaft 132 is fixedly connected to the inner wall of the shaft mounting groove 14. A spacing is provided between the inner shaft 131 and the outer shaft 132. A plurality of balls or rollers are generally provided inside the spacing as a sliding structure. In the present device, the oil groove 51 is located just below the spacing. When the oil emerges from the oil groove 51, it enters the spacing between the inner shaft 131 and the outer shaft 132 and is contacted by a plurality of balls or rollers. As the inner shaft 131 rotates, the lubricating oil contacts the outer sides of all the balls or rollers, thereby enhancing the lubrication of the bearing 13 and avoiding the increase of friction or damage to the bearing 13, thereby affecting the vibration effect caused by the rotation of the rotating shaft 12 and the eccentric shaft 121. An oil delivery component 5 may also be provided on the lower side of the bearing 13 at the lower end of the rotating shaft 12.

[0042] like Figure 6-7 As shown, an annular groove 53 and a plurality of cylindrical grooves 52 above the annular groove 53 are provided inside the oil delivery component 5. An oil groove 51 is also provided inside the oil delivery component 5. The oil groove 51 is communicated with the plurality of cylindrical grooves 52. One end of a plurality of water delivery hoses 41 is communicated with the annular groove 53. A lifting ring 54 is movably installed inside the annular groove 53. A plurality of spring guide columns 541 are installed at the bottom of the lifting ring 54. The lower ends of the plurality of spring guide columns 541 are installed on the inner bottom wall of the annular groove 53. The interior of the annular groove 53 is divided by the lifting ring 54. Water is stored below the lifting ring 54, and oil is stored above the lifting ring 54.

[0043] The width of the bottom groove of the oil groove 51 is consistent with the diameter of the cylindrical groove 52 , the width of the top groove of the oil groove 51 is smaller than the width of the bottom groove of the oil groove 51 , and a one-way cylinder 6 is fixedly installed inside the cylindrical groove 52 .

[0044] Specifically, water input through multiple water delivery hoses 41 enters the lower part of the annular groove 53. When the water accumulated in the lower part of the annular groove 53 is enough, the lifting ring 54 will be pushed up. At this time, the spring guide column 541 is deformed, and lubricating oil is stored in the upper part of the annular groove 53. As the lifting ring 54 rises, the lubricating oil in the upper part of the annular groove 53 will be squeezed, allowing the lubricating oil to enter the cylindrical groove 52 through multiple one-way cylinders 6. The cylindrical groove 52 is designed to be wide at the bottom and narrow at the top, so that the lubricating oil entering the cylindrical groove 52 will first accumulate at the bottom of the cylindrical groove 52, and then the liquid level will rise evenly to the top of the oil groove 51. Finally, it is exposed to the upper outer side of the oil groove 51 and enters into the gap between the inner shaft 131 and the outer shaft 132 to lubricate the bearing 13, ensuring that the device can perform vibration work for a long time. Inside the annular groove 53, it is separated by the lifting ring 54. At this time, water is at the bottom and oil is at the top. Even if the lifting ring 54 cannot completely separate the water and oil, the oil will always float on the top. When the lifting ring 54 rises, the oil must be squeezed out first. The water at the bottom of the lifting ring 54 can enter again and again, that is, the lifting ring 54 can be lifted again and again, and then the oil can be squeezed out multiple times to lubricate the bearing 13.

[0045] Embodiment 2

[0046] like Figure 8-9 As shown, comparative example 1, wherein another implementation of the present invention is: a component groove 62, a connecting groove 1 63 and a connecting groove 2 64 are sequentially provided inside the one-way cylinder 6 from top to bottom, the component groove 62, the connecting groove 1 63 and the connecting groove 2 64 are all connected, a liquid outlet groove 61 is provided on the side of the connecting groove 1 63, the liquid outlet groove 61 is connected to the oil groove 51, a liquid inlet groove 65 is provided on the lower side of the connecting groove 2 64, the liquid inlet groove 65 is connected to the annular groove 53, and a one-way valve core 7 is installed inside the one-way cylinder 6.

[0047] The one-way valve core 7 includes a fixed column 71 fixedly installed inside the connecting groove 64 and a fixed ring 74 fixedly installed inside the component groove 62. A lifting column 73 is slidably installed inside the fixed ring 74. A limiting ring 75 is fixedly installed on the upper end of the lifting column 73. The limiting ring 75 is slidably installed inside the component groove 62. An inner groove 76 is provided inside the limiting ring 75 and the lifting column 73. A compression spring 77 is fixedly installed inside the inner groove 76. One end of the compression spring 77 is connected to the inner top wall of the component groove 62. A cone 72 is installed at the lower end of the lifting column 73. The cone 72 contacts the fixed column 71. The bottom diameter of the cone 72 is smaller than the diameter of the connecting groove 64, and the top diameter of the cone 72 is larger than the diameter of the connecting groove 64.

[0048] Specifically, when the concrete needs to be vibrated and compacted, the portable motor 2 is used for electric drive. With the cooperation of the flexible shaft connector 3, the rotating shaft 12 and the eccentric shaft 121 rotate inside the vibrating rod 1. When the eccentric shaft 121 rotates as an eccentric structure, it will drive the vibrating rod 1 to vibrate. The vibrating rod 1 is placed inside the concrete for vibration. The vibrating rod 1 vibrates at different positions of the concrete. At this time, the bubbles inside the concrete will float to the surface, and then the bubbles will be removed to achieve the purpose of compacting the concrete. An oil delivery component 5 is provided inside the vibrating rod 1. Lubricating oil is stored inside the oil delivery component 5. When the rotating When the shaft 12 and the eccentric shaft 121 rotate for too long, the bearing 13 installed on the outside of the rotating shaft 12 will be damaged. At this time, the lubricating oil inside the oil delivery component 5 can be squeezed out, that is, it appears inside the oil groove 51, and the lubricating oil will contact the bearing 13 to lubricate it, ensuring that the rotating shaft 12 and the eccentric shaft 121 can rotate for a longer time, that is, the vibrating rod 1 can vibrate the concrete for a longer time. When the lifting ring 54 rises inside the annular groove 53 to squeeze the lubricating oil, the lubricating oil will enter the inside of the one-way cylinder 6 through the liquid inlet groove 65. As the lubricating oil enters the liquid inlet groove 65 and even the connecting groove 64, the cone 72 will be lifted up. The lifting column 73 and the limit ring 75 rise, and the compression spring 77 is compressed. After the cone 72 rises, there will be a certain distance between it and the top of the fixed column 71. At this time, the lubricating oil enters the inside of the connecting groove 63 through this distance, and then enters the inside of the oil groove 51 through the liquid outlet groove 61 to lubricate the bearing 13. The water pumped out from the water pump assembly 4 through the water hose 41 will first lift the lifting ring 54 to rise a distance to squeeze the oil, and then will extract the water at the bottom of the lifting ring 54. With the cooperation of the spring guide column 541, the lifting ring 54 is allowed to drop a small distance. This drop distance is less than the rise distance of the lifting ring 54, that is, the lubricating oil enters the single When it is directed into the cylinder 6, the cone 72 is first lifted up to allow the oil to pass through. Then, when the lifting ring 54 descends, a part of the oil in the liquid inlet groove 65 is withdrawn. At this time, under the action of the restoring force of the compression spring 77, the cone 72 descends and contacts the top of the fixed column 71 again, closing the channel, so that the oil in the oil groove 51 and the annular groove 53 do not circulate. The oil can only flow from the annular groove 53 to the oil groove 51 in one direction, so that the lubricating oil in the oil groove 51 can fully play a lubricating role. With the repeated use of the flexible shaft connector 3 and the vibrating rod 1, the lubricating oil at the bottom of the oil groove 51 will also be ejected, and enter the spacing position between the inner shaft 131 and the outer shaft 132 through the guide at the top of the oil groove 51.

[0049] Working principle: water input through multiple water hoses 41 enters the lower part of the annular groove 53. When the water accumulated in the lower part of the annular groove 53 is enough, it will push the lifting ring 54 to rise. At this time, the spring guide column 541 is deformed, and lubricating oil is stored in the upper part of the annular groove 53. As the lifting ring 54 rises, it will squeeze the lubricating oil in the upper part of the annular groove 53, allowing the lubricating oil to enter the cylindrical groove 52 through multiple one-way cylinders 6. The cylindrical groove 52 is designed to be wide at the bottom and narrow at the top, so that the lubricating oil entering the cylindrical groove 52 will first accumulate at the bottom of the cylindrical groove 52, and then the liquid level will rise evenly to the top of the oil groove 51 , and finally emerges to the upper outer side of the oil groove 51, enters into the gap between the inner shaft 131 and the outer shaft 132, lubricates the bearing 13, and ensures that the device can perform vibration work for a long time. Inside the annular groove 53, it is separated by the lifting ring 54. At this time, water is at the bottom and oil is at the top. Even if the lifting ring 54 cannot completely separate the water and oil, the oil will always float on the top. When the lifting ring 54 rises, the oil must be squeezed out first. The water at the bottom of the lifting ring 54 can enter again and again, that is, the lifting ring 54 can be lifted again and again, and then the oil can be squeezed out many times to lubricate the bearing 13.
