Description
Technical Field
[0001] This utility model relates to the field of mixer technology, and more specifically, to a cement mixer that is easy to load. Background Technology
[0002] A cement mixer is a mechanical device used to mix materials such as cement, sand, gravel, and water into concrete. Vertical cement mixers are a common type of cement mixer. They range in size from small to large, with heights ranging from one to six meters. They generally consist of a vertical mixing tank, a mixing shaft, mixing blades, a drive motor, and a reducer. Operators use a shovel to directly transport the raw materials to the top of the mixing tank. After mixing by the mixing blades, the discharge port at the bottom of the mixing tank is opened. However, transporting raw materials directly to a high place with a shovel is laborious and can easily cause sprains for the user during operation, which affects the efficiency of loading to some extent. To address the shortcomings of existing technology, we propose a cement mixer that is easier to load. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a cement mixer that is easy to load, so as to solve the problem that it is laborious to transport raw materials directly to a high place with a shovel, and users are prone to twisting their ankles during the operation, which affects the loading efficiency to a certain extent.
[0004] To solve the above technical problems, the present invention provides the following technical solution: a cement mixer that is easy to load, including a mixing tank, a mixing shaft is provided inside the mixing tank, a plurality of mixing blades are fixedly connected to the outer wall of the mixing shaft, a loading assembly is provided on the left side of the mixing tank, and an observation assembly is provided on the right side of the loading assembly.
[0005] The loading assembly includes an electric slide rail, which is fixedly connected to the outer wall of the mixing tank. A sliding frame is provided on the top of the electric slide rail, and the electric slide rail is used to control the left and right sliding of the sliding frame. A U-shaped frame and two guide rods are fixedly installed on the top of the sliding frame, and the top ends of the two guide rods are fixedly connected to the bottom end of the U-shaped frame. A threaded rod is rotatably connected to the top of the sliding frame. A motor is fixedly installed on one outer surface of the U-shaped frame, and the output end of the motor is fixedly connected to the top end of the threaded rod. A roller frame is fixedly installed at the bottom of the U-shaped frame. Lifting frames are slidably connected to the outer walls of the two guide rods. A material container is rotatably connected to the outer surface of the adjacent side of the two lifting frames. A baffle is fixedly connected to the top of the two lifting frames.
[0006] The two guide rods and the two lifting frames are symmetrically distributed on both sides of the width of the material container, and the threaded rod is threadedly connected to the inner wall of one of the lifting frames. The two guide rods are used to restrict the movement direction of the two lifting frames to be parallel to the vertical direction.
[0007] The center of gravity of the material container is located on the left side of the rotatable connection between the two lifting frames, the roller frame is located directly above the right side profile of the material container, and the baffle is used to prevent the right side of the material container from tilting up.
[0008] The observation assembly includes a square frame, which is fixedly connected to the inner wall of the mixing tank. A movable rod is slidably connected to the inner wall of the square frame. A buoy is fixedly connected to the bottom end of the movable rod. A retaining ring is fixedly connected to the outer wall of the movable rod. A mechanical slide rail and a scale are fixedly installed on the outer wall of the mixing tank. A slider is slidably connected to one side of the outer surface of the mechanical slide rail, and the slider is located on one side of the scale. A rope is fixedly connected to the top end of the movable rod. A fixed pulley is fixedly installed on the top of the mixing tank.
[0009] The buoy weighs more than the slider, the rope is in contact with the outer wall of the fixed pulley, and the end of the rope away from the movable rod is fixedly connected to the slider.
[0010] The retaining ring is attached to the top surface of the square frame, and the length direction of the movable rod, mechanical slide rail and scale is parallel to the central axis of the mixing tank.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention utilizes a loading assembly, including a loading basin, to move two lifting frames and the loading basin to a lower position. Cement raw materials are shoveled into the loading basin. Then, a threaded rod drives the loading basin to move upward along two guide rods. When the loading basin is above the mixing tank, an electric slide rail is activated to move the loading basin to the right. The threaded rod then drives the loading basin to continue rising. At this point, the right contour of the loading basin contacts the roller frame, thereby pushing the loading basin to rotate clockwise and pour the raw materials in the loading basin into the mixing tank. Then, the electric slide rail moves the loading basin away from the mixing tank, and the threaded rod drives the loading basin to descend. Using the above structure, the cement raw materials can be transported to the top of the mixing tank by raising and lowering the loading basin via a motor and a threaded rod. This saves the user's physical strength, reduces the risk of user sprains during operation, improves loading efficiency, and enhances the flexibility of the device.
[0013] This invention utilizes an observation component, including a buoy and a scale. As the amount of material inside the mixing tank increases, the buoy rises accordingly, causing the rope to slacken. The slider then descends along a mechanical rail until the rope tightens again. Based on the relative position of the slider and the scale, the depth of the material inside the mixing tank can be determined by observing the scale's graduations. This structure, by raising and lowering the buoy, drives the slider outside the mixing tank to rise and fall, allowing users to easily observe the depth of the material inside the mixing tank and control the material ratio, thus improving the device's practicality.

[0019] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0020] As attached Figure 1 To be continued Figure 3 An embodiment of this utility model provides a cement mixer that is easy to load, including a mixing tank 1, a mixing shaft 2 is provided inside the mixing tank 1, a plurality of mixing blades 3 are fixedly connected to the outer wall of the mixing shaft 2, a loading assembly 4 is provided on the left side of the mixing tank 1, and an observation assembly 5 is provided on the right side of the loading assembly 4.
[0021] The loading assembly 4 includes an electric slide rail 41, which is fixedly connected to the outer wall of the mixing tank 1. A sliding frame 42 is provided on the top of the electric slide rail 41, and the electric slide rail 41 is used to control the left and right sliding of the sliding frame 42. A U-shaped frame 43 and two guide rods 44 are fixedly installed on the top of the sliding frame 42, and the top ends of the two guide rods 44 are fixedly connected to the bottom end of the U-shaped frame 43. A threaded rod 45 is rotatably connected to the top of the sliding frame 42. A motor 46 is fixedly installed on one outer surface of the U-shaped frame 43, and the output end of the motor 46 is fixedly connected to the top end of the threaded rod 45. A roller frame 47 is fixedly installed at the bottom of the U-shaped frame 43. Lifting frames 48 are slidably connected to the outer walls of the two guide rods 44. A material container 49 is rotatably connected to the outer surface of the adjacent side of the two lifting frames 48. A baffle 411 is fixedly connected to the top of the two lifting frames 48.
[0022] Among them, two guide rods 44 and two lifting frames 48 are symmetrically distributed on both sides of the width direction of the material container 49, and the threaded rod 45 is threadedly connected to the inner wall of one of the lifting frames 48. The two guide rods 44 are used to limit the movement direction of the two lifting frames 48 to be parallel to the vertical direction.
[0023] The motor 46 drives the threaded rod 45 to rotate, which can drive the lifting frame 48 to rise and fall. Since the two lifting frames 48 are fixedly connected to the baffle 411, the material container 49 will rise and fall together. The electric slide rail 41 drives the material container 49 to move left and right, which can prevent the material container 49 from interfering with the mixing tank 1 during the lifting and falling process.
[0024] Among them, the center of gravity of the material container 49 is located on the left side of the rotatable connection with the two lifting frames 48, the roller frame 47 is located directly above the right side profile of the material container 49, and the baffle 411 is used to prevent the right side of the material container 49 from tilting up.
[0025] By shifting the center of gravity of the material container 49 to the left and preventing the right side of the material container 49 from tilting up, the material container 49 will not flip over during the lifting and lowering process. When the right contour of the material container 49 contacts the roller frame 47, it will push the material container 49 to flip clockwise and pour out the raw materials in the material container 49.
[0026] The observation component 5 includes a square frame 51, which is fixedly connected to the inner wall of the mixing tank 1. A movable rod 52 is slidably connected to the inner wall of the square frame 51. A buoy 53 is fixedly connected to the bottom end of the movable rod 52. A retaining ring 54 is fixedly connected to the outer wall of the movable rod 52. A mechanical slide rail 55 and a scale 56 are fixedly installed on the outer wall of the mixing tank 1. A slider 57 is slidably connected to one side of the outer surface of the mechanical slide rail 55, and the slider 57 is located on one side of the scale 56. A rope 58 is fixedly connected to the top end of the movable rod 52. A fixed pulley 59 is fixedly installed on the top of the mixing tank 1.
[0027] Among them, the weight of the buoy 53 is greater than the weight of the slider 57, the rope 58 is in contact with the outer wall of the fixed pulley 59, and the end of the rope 58 away from the movable rod 52 is fixedly connected to the slider 57.
[0028] The float 53 can be raised as the amount of cement material inside the mixing tank 1 increases. At this time, the slider 57 will descend along the scale 56, so the depth of the cement material inside the mixing tank 1 can be observed based on the relative position of the slider 57 and the scale 56.
[0029] Among them, the retaining ring 54 is in contact with the top surface of the square frame 51, and the length direction of the movable rod 52, the mechanical slide rail 55 and the scale 56 is parallel to the central axis direction of the mixing tank 1.
[0030] The movement range of the float 53 can be limited by the retaining ring 54, thereby preventing the float 53 from contacting the stirring blade 3.
[0031] The working process of this utility model is as follows:
[0032] First, the motor 46 drives the threaded rod 45 to rotate, moving the two lifting frames 48 and the material container 49 to a lower position, shoveling the cement raw materials into the material container 49. Then, the threaded rod 45 drives the material container 49 to move upward along the two guide rods 44. When the material container 49 is above the mixing tank 1, the electric slide rail 41 is activated to move the material container 49 to the right. Then, the threaded rod 45 drives the material container 49 to continue rising. At this time, the right contour of the material container 49 contacts the roller frame 47, thereby pushing the material container 49 smoothly. The clock hand rotates, pouring the raw material from the container 49 into the mixing tank 1. Then, the electric slide rail 41 moves the container 49 away from the mixing tank 1, and the threaded rod 45 drives the container 49 to descend. As the amount of raw material in the inner cavity of the mixing tank 1 increases, the float 53 rises accordingly. At this time, the rope 58 begins to slack, and then the slider 57 descends along the mechanical slide rail 55 until the rope 58 becomes taut again. Based on the relative position of the slider 57 and the scale 56, the depth of the raw material in the inner cavity of the mixing tank 1 can be determined by observing the scale 56.
