[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a concrete mixer for paving. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A concrete mixer for paving includes a base frame 1 and a vibrating frame 2. A tank 21 is rotatably installed inside the vibrating frame 2. A motor 3 is fixedly installed on the top of the base frame 1. A rotating shaft 4 is fixedly connected to the output end of the motor 3. One end of the rotating shaft 4 passes through the base frame 1 and is rotatably connected to the inner cavity of the base frame 1. A mixing rod 5 is slidably sleeved on one end of the rotating shaft 4. The mixing rod 5 is used in conjunction with the tank 21. A lifting assembly 6 is provided on the surface of the base frame 1. A vibration assembly 7 is provided inside the base frame 1.

[0025] The vibration assembly 7 includes a drive shaft 71, which is rotatably connected inside the base frame 1. A crankshaft 72 is rotatably connected inside the base frame 1 and works in conjunction with the drive shaft 71. A first spring 73 is fixedly connected to the bottom of the vibration frame 2. One end of the first spring 73 is fixedly connected to a top plate 74 and works in conjunction with the top plate 74. A second spring 75 is fixedly installed at the bottom of the vibration frame 2 and one end of the second spring 75 is fixedly connected to the surface of the base frame 1.

[0026] When concrete mixing is required, the concrete is placed in the tank 21, and then the motor 3 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the mixing rod 5 to rotate, so that the concrete is mixed by the mixing rod 5. At the same time, the rotating shaft 4 drives the transmission shaft 71 to rotate, so that the transmission shaft 71 drives the crankshaft 72 to rotate. The crankshaft 72 intermittently lifts the top plate 74 upward. The top plate 74 lifts the vibrating frame 2 through the first spring 73, and through the elastic support of the first spring 73 and the second spring 75, the vibrating frame 2 vibrates and transmits the vibration to the tank 21, thereby dispersing the agglomerated cement and effectively improving the uniformity and efficiency of concrete mixing.

[0027] Reference Figure 2 and Figure 4 A first gear 7101 and a first bevel gear 7104 are fixedly sleeved on the surface of the drive shaft 71, and a second gear 7102 is fixedly sleeved on the surface of the rotating shaft 4. The surfaces of the first gear 7101 and the second gear 7102 are jointly sleeved with a synchronous toothed belt 7103. A second bevel gear 7105 is fixedly sleeved on the surface of the crankshaft 72, and the surface of the second bevel gear 7105 meshes with the surface of the first bevel gear 7104. When the rotating shaft 4 rotates, the rotating shaft 4 drives the second gear 7102 to rotate, and the second gear 7102 causes the first gear 7101 to rotate through the synchronous toothed belt 7103, so that the first gear 7101 drives the drive shaft 71 to rotate, thereby causing the drive shaft 71 to drive the first bevel gear 7104 to rotate, and the first bevel gear 7104 drives the second bevel gear 7105 to rotate, thereby achieving the function of rotating the crankshaft 72.

[0028] Reference Figure 2 and Figure 3A first limiting sleeve 7301 is fixedly connected to the side of the top plate 74 opposite to the vibrating frame 2. A first limiting rod 7302 is fixedly connected to the side of the vibrating frame 2 opposite to the top plate 74. One end of the first limiting rod 7302 is slidably connected to the inside of the first limiting sleeve 7301. The surfaces of the first limiting rod 7302 and the first limiting sleeve 7301 are both slidably connected to the inner cavity of the first spring 73. A second limiting sleeve 7501 is fixedly connected to the side of the base frame 1 opposite to the vibrating frame 2. A second limiting rod 7502 is fixedly connected to the side of the vibrating frame 2 opposite to the base frame 1. One end of the second limiting rod 7502 is slidably connected to the inside of the second limiting sleeve 7501. The second limiting rod 7502 and the second limiting sleeve 7501 are slidably connected to the inner cavity of the base frame 73. The surface of sleeve 7501 is slidably connected to the inner cavity of the second spring 75. One end of the first limiting rod 7302 is slidably connected to the inside of the first limiting sleeve 7301 to stabilize the position of the first spring 73 and prevent the first spring 73 from twisting or deforming. This allows the first spring 73 to transmit vibration to the vibration frame 2. The second limiting sleeve 7501 and the second limiting rod 7502 stabilize the position of the second spring 75 so that when the vibration frame 2 vibrates, the second spring 75 increases the vibration frequency of the vibration frame 2 and prevents the second spring 75 from twisting or deforming, which would affect its support effect.

[0029] Reference Figure 1 A positioning frame 22 is fixedly installed on the surface of the vibration frame 2, and a positioning rod 2201 is fixedly installed inside the base frame 1. The positioning frame 22 is slidably sleeved on the surface of the positioning rod 2201. By sliding the positioning frame 22 on the surface of the positioning rod 2201, the position of the vibration frame 2 is stabilized by the positioning rod 2201 and the positioning frame 22, so as to avoid the vibration frame 2 from being displaced and affecting the position of the tank 21.

[0030] Reference Figure 4 and Figure 5 The rotating shaft 4 has a connecting groove 41 on its surface, and a connecting block 42 is fixedly installed on the inner wall of the mixing rod 5. The surface of the connecting block 42 is slidably connected to the inner cavity of the connecting groove 41. By sliding the surface of the connecting block 42 to the inner cavity of the connecting groove 41, the rotating shaft 4 can drive the mixing rod 5 to rotate through the connecting block 42 and the connecting groove 41 when it rotates, thus avoiding the rotating shaft 4 from spinning freely inside the mixing rod 5 and causing the mixing rod 5 to be unable to perform the concrete mixing work.

[0031] Reference Figure 4 and Figure 5The lifting assembly 6 includes a hydraulic cylinder 61, which is fixedly installed on the top of the base frame 1. The telescopic end of the hydraulic cylinder 61 passes through the base frame 1 and is slidably connected to the inner cavity of the base frame 1. A connecting frame 62 is fixedly connected to the telescopic end of the hydraulic cylinder 61. The connecting frame 62 is rotatably sleeved on the surface of the mixing rod 5. A support block 64 is fixedly installed on the surface of the mixing rod 5. The support block 64 is rotatably connected to the inside of the connecting frame 62. A support rod 63 is fixedly connected to the side of the connecting frame 62 opposite to the base frame 1. One end of the support rod 63 passes through the base frame 1 and is slidably connected to the inner cavity of the base frame 1. After the concrete mixing is completed, the hydraulic cylinder 61 drives the connecting frame 62 to move upward, and the support rod 63 stabilizes the position of the connecting frame 62. The support block 64 causes the connecting frame 62 to drive the mixing rod 5 to move simultaneously, so that the mixing rod 5 is separated from the tank 21, so that the concrete in the tank 21 can be poured out for paving.

[0032] Working principle: When concrete mixing is required, concrete is placed in tank 21. Motor 3 drives shaft 4 to rotate, which in turn drives mixing rod 5 via connecting block 42 and connecting groove 41. Simultaneously, shaft 4 drives second gear 7102, which in turn drives first gear 7101 via synchronous belt 7103. First gear 7101 drives transmission shaft 71, which in turn drives first bevel gear 7104. First bevel gear 7104 drives second bevel gear 7105, which in turn drives crankshaft 72. Crankshaft 72 intermittently lifts top plate 74. One end of first limiting rod 7302 is slidably connected to the inside of first limiting sleeve 7301, stabilizing first spring 74 through the first limiting rod 7302 and first limiting sleeve 7301. Position 3 prevents the first spring 73 from twisting or deforming, allowing the top plate 74 to lift the vibrating frame 2 via the first spring 73. The second limit sleeve 7501 and the second limit rod 7502 stabilize the position of the second spring 75, allowing the vibrating frame 2 to quickly return to its original position after moving upward. The positioning rod 2201 and the positioning frame 22 stabilize the position of the vibrating frame 2, causing it to vibrate under the elastic action of the first spring 73 and the second spring 75. The vibrating frame 2 transmits the vibration to the tank 21, thereby dispersing the agglomerated cement and effectively improving the uniformity and efficiency of concrete mixing. After the concrete mixing is completed, the hydraulic cylinder 61 drives the connecting frame 62 to move upward, and the support rod 63 stabilizes the position of the connecting frame 62. The support block 64 causes the connecting frame 62 to move the mixing rod 5 simultaneously, separating the mixing rod 5 from the tank 21 so that the concrete in the tank 21 can be poured out for paving.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
