Description

Technical Field

[0001] This utility model relates to the technical field of cement mixing equipment, specifically to a cement mixer. Background Technology

[0002] A cement mixer, also known as a concrete mixer, is a machine that uses blades rotating in a cylinder or trough to mix various raw materials into a mixture or a mixture of suitable consistency.

[0003] In existing cement mixers, the mixing tank is tilted and inverted during discharge, allowing the concrete inside to flow down naturally under gravity. However, due to the high viscosity of the mixed concrete, gravity flow alone cannot quickly discharge the concrete from the tank, limiting the discharge efficiency of the device. In addition, some concrete still adheres to the inner wall of the tank after discharge, resulting in insufficient discharge. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a cement mixer.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A cement mixer, comprising:

[0007] frame;

[0008] A rotating frame is rotatably mounted on the machine frame;

[0009] The mixing tank is fixed on the rotating frame;

[0010] Two connecting structures are provided, and the rotating frame is connected to the machine frame through the two connecting structures.

[0011] A vibration structure, mounted on the frame, is used to generate vibration in the mixing tank.

[0012] As a further embodiment of this utility model: the connection structure includes:

[0013] The outer cylinder is rotatably mounted on the frame;

[0014] An inner rod is slidably disposed inside the outer cylinder, with one end of the inner rod extending to the outside of the outer cylinder and fixedly connected to the rotating frame;

[0015] The spring has one end connected to the outer cylinder and the other end connected to the inner rod;

[0016] Spline, fixed to the inner rod;

[0017] A spline groove is formed on the inner ring of the outer cylinder, and the spline is slidably disposed in the spline groove.

[0018] As a further embodiment of this utility model: the vibration structure includes:

[0019] The mounting cylinder is fixed on the frame, and the end of the mounting cylinder facing the rotating frame is open.

[0020] A rotating block is rotatably mounted inside the mounting cylinder;

[0021] The movable block is slidably disposed within the mounting cylinder;

[0022] A rotating shaft passes through the frame and is rotatably connected to the frame. One end of the rotating shaft extends into the interior of the mounting cylinder and is fixedly connected to the rotating block.

[0023] A limiting port is provided on the mounting cylinder;

[0024] A limiting block is fixed on the movable block, and the limiting block is slidably disposed in the limiting opening;

[0025] A tension spring, one end of which is connected to the mounting cylinder, and the other end of which is connected to the limiting block.

[0026] As a further embodiment of this utility model: the rotating block and the moving block together form a cylindrical structure, the rotating block and the moving block are the same size, and each of the rotating block and the moving block has an inclined surface at one end opposite to each other, and the outer edges of the rotating block and the moving block are in contact with the inner surface of the mounting cylinder.

[0027] As a further embodiment of this utility model, the rotating block, the moving block and the rotating shaft are arranged coaxially.

[0028] As a further embodiment of this utility model, the inner surface of the outer cylinder and the outer surface of the inner rod are fitted together.

[0029] The beneficial effects of this utility model are:

[0030] When the rotating block rotates, its inclined surface squeezes the moving block, causing the moving block to vibrate within the mounting cylinder. This vibration drives the rotating frame and the mixing tank on it to vibrate as well, thereby accelerating the flow of concrete within the mixing tank and enabling the concrete to flow out quickly and smoothly, significantly improving discharge efficiency. In addition, the vibration of the mixing tank effectively reduces the adhesion and residue of concrete on the inner wall of the mixing tank. The vibration reduces the friction between concrete particles, making it easier for them to detach from the inner wall of the mixing tank, thus achieving more complete discharge and avoiding concrete waste and the hassle of cleaning the mixing tank.

[0038] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0039] like Figure 1-5 As shown, a cement mixer includes: a frame 1; a rotating frame 2 rotatably mounted on the frame 1; and a mixing tank 3 fixed on the rotating frame 2.

[0040] The cement mixer also includes two connecting structures. The rotating frame 2 is connected to the frame 1 through the two connecting structures. The connecting structures include: an outer cylinder 41, which is rotatably mounted on the frame 1; an inner rod 42, which is slidably disposed inside the outer cylinder 41, with one end of the inner rod 42 extending to the outside of the outer cylinder 41 and fixedly connected to the rotating frame 2, and the inner surface of the outer cylinder 41 and the outer surface of the inner rod 42 fitting together; a spring 43, with one end connected to the outer cylinder 41 and the other end connected to the inner rod 42; a spline 44, which is fixed on the inner rod 42; and a spline groove 45, which is opened on the inner ring of the outer cylinder 41, with the spline 44 slidably disposed in the spline groove 45. When material needs to be discharged, the operator rotates the handwheel on one of the outer cylinders 41, causing the corresponding outer cylinder 41 to rotate. When the outer cylinder 41 rotates, it can drive the corresponding inner rod 42 to rotate through the spline groove 45 and the spline 44, which causes the rotating frame 2 and the mixing tank 3 to rotate together until the opening of the mixing tank 3 faces downward.

[0041] The cement mixer also includes a vibration structure mounted on the frame 1 for generating vibration in the mixing tank 3. The vibration structure includes: a mounting cylinder 51 fixed to the frame 1, with one end of the mounting cylinder 51 open towards the rotating frame 2; a rotating block 52 rotatably mounted inside the mounting cylinder 51; and a movable block 53 slidably mounted inside the mounting cylinder 51. The rotating block 52 and the movable block 53 together form a cylindrical structure, with the same size. Both the rotating block 52 and the movable block 53 have inclined surfaces at opposite ends, and their outer edges are in contact with the inner surface of the mounting cylinder 51; and a rotating shaft 54 ​​passing through the frame 1 and rotatably connected to it. One end of the rotating shaft 54 ​​extends into the interior of the mounting cylinder 51 and is fixedly connected to the rotating block 52. The moving block 53 and the rotating shaft 54 ​​are coaxially arranged; the limiting port 55 is opened on the mounting cylinder 51; the limiting block 56 is fixed on the moving block 53 and is slidably arranged in the limiting port 55; the tension spring 57 is connected at one end to the mounting cylinder 51 and at the other end to the limiting block 56. When the rotating block 52 squeezes the moving block 53, the moving block 53 can extend out of the mounting cylinder 51. Conversely, the moving block 53 will be reset under the action of the tension spring 57. In summary, with the rotation of the rotating shaft 54, the moving block 53 will vibrate. During the vibration, the moving block 53 will continuously push the rotating frame 2, causing the rotating frame 2 and the mixing tank 3 on it to vibrate as well. When the mixing tank 3 vibrates, the concrete inside will flow out quickly under the action of the vibration force, thereby improving the discharge efficiency.

[0042] The working principle of this utility model:

[0043] When the cement mixer proposed in this utility model needs to discharge material, the operator rotates the handwheel on one of the outer cylinders 41, causing the corresponding outer cylinder 41 to rotate. The rotation of the outer cylinder 41 drives the corresponding inner rod 42 to rotate via the spline groove 45 and spline 44, causing the rotating frame 2 and the mixing tank 3 to rotate accordingly until the opening of the mixing tank 3 faces downwards. In this case, the cement inside the mixing tank 3 will flow downwards under its own weight. During the discharge process, the operator rotates the rotating shaft 54, which drives the rotating block 52 to rotate. Since the rotating block 52 and the moving block 53 together form a cylindrical structure, and the rotating block 52 and the moving block 53 are the same size, each end of the rotating block 52 and the moving block 53 has an inclined surface. The outer edges of the rotating block 52 and the moving block 53 are in contact with the inner surface of the chamber. Therefore, during the rotation of the rotating block 52, its inclined surface portion... The inclined portion of the movable block 53 can be squeezed. Under the limiting action of the limiting port 55 and the limiting block 56, the movable block 53 cannot rotate with the rotating block 52. Therefore, the movable block 53 will move under the squeezing action of the rotating block 52. Thus, when the rotating block 52 squeezes the movable block 53, the movable block 53 can extend out of the mounting cylinder 51. Conversely, the movable block 53 will reset under the action of the tension spring 57. In summary, with the rotation of the rotating shaft 54, the movable block 53 will vibrate. During the vibration process, the movable block 53 will continuously push the rotating frame 2, causing the rotating frame 2 and the mixing tank 3 on it to vibrate as well. When the mixing tank 3 vibrates, the concrete inside will flow out quickly under the action of the vibration force, thereby improving the discharge efficiency. In addition, the vibration action of the mixing tank 3 can also reduce the concrete residue on the inner wall of the mixing tank 3, which is conducive to achieving full discharge.

[0044] During the vibration of the mixing tank 3, the two inner rods 42 will slide inside the two outer cylinders 41, and the two springs 43 set between the two outer cylinders 41 and the two inner rods 42 also facilitate the vibration of the mixing tank 3.

[0045] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
