Description

Technical Field

[0001] This utility model relates to a mixing device, specifically a concrete vibration mixing device, belonging to the field of concrete processing technology. Background Technology

[0002] Concrete, often simply called "concrete," is a building material widely used in civil engineering. Its main components include cement, sand, and stone, which, when mixed with water, form a plastic mixture. Before hardening, this mixture is called concrete mix or fresh concrete. Hardened concrete has high compressive strength, good durability, and certain thermal insulation properties, and is therefore used to construct various buildings and infrastructure. When the construction site is in a location with inconvenient transportation, or when the amount of concrete required for construction is small, small concrete mixing equipment can be used to produce concrete.

[0003] Chinese Patent Publication No. CN221736628U discloses a concrete mixing device, relating to the technical field of mixing devices. It includes a mixing tank and a fixed frame. Support legs are symmetrically fixed to the bottom of the fixed frame, and a water inlet pipe is fixedly installed to the top of the mixing tank. This invention incorporates a motor, a rotating shaft, a stirring rod, a scraper, a water distribution tank, a cleaning water pipe, and nozzles. Cleaning water is supplied through the cleaning water pipe, enters the water distribution tank, and is then sprayed out from multiple nozzles.

[0004] However, the inventor of the above-mentioned device believes that it has certain defects. The device is relatively simple in terms of mixing function and can only achieve the function of stirring. Relying solely on the rotation of the stirring blades is not enough to ensure the uniform distribution of the various components of the concrete, resulting in poor mixing effect and reduced concrete production quality. Therefore, this utility model provides a concrete vibration mixing device. Utility Model Content

[0005] (a) Technical problems to be solved The purpose of this invention is to provide a concrete vibration mixing device to solve the above-mentioned problems, thereby addressing the issue that relying solely on the rotation of the mixing blades in the prior art makes it difficult to ensure the uniform distribution of concrete components and reduces the production quality of concrete.

[0006] (II) Technical Solution This utility model is achieved through the following technical solution: a concrete vibration mixing device, including a fixed base and a mounting frame. A mixing cylinder is fixedly connected to the fixed base, and a discharge pipe is fixedly connected to the mixing cylinder. The mounting frame is provided with a mixing mechanism and a vibration mechanism for mixing the concrete inside the mixing cylinder.

[0008] Preferably, one end of the fixed seat is fixedly connected to a vibration host that is connected to the vibrating rod, and the bottom of the slider is provided with a fixing mechanism for fixing the vibrating rod. By installing the vibration host of the vibrating rod at one end of the fixed seat, the vibration mechanism is driven to rotate together during the rotation of the fixed seat.

[0009] Preferably, the fixing mechanism includes a connecting frame fixed to the bottom of the slider. One end of the connecting frame is detachably connected to a connecting clip by bolts. The vibrator is clamped between the connecting clip and the connecting frame. The vibrator can be removed for cleaning by removing the bolts on the connecting clip to separate the connecting clip from the connecting frame.

[0010] Preferably, one end of the reciprocating lead screw extends to the outside of the fixed base, and a connecting bevel gear is fixedly connected to one end of the reciprocating lead screw. A bevel gear ring is fixedly connected to the bottom of the mounting bracket. The connecting bevel gear meshes with the bevel gear ring. When the fixed base rotates, the reciprocating lead screw is driven to rotate by the action of the bevel gear ring and the connecting bevel gear.

[0011] Preferably, the top of the fixed base is fixedly connected to two connecting seats, each of which has a sliding groove. The outer surface of the mounting frame is fixedly connected to two sliding blocks, which slide inside the two sliding grooves respectively. Through the action of the two sliding blocks and the two sliding grooves, the mounting frame is stably raised and lowered directly above the mixing cylinder.

An adjusting motor that drives the adjusting screw to rotate is fixedly connected to the top of the connecting seat. By starting the adjusting motor, the adjusting screw is driven to rotate, and under the action of the sliding block, the mounting bracket is driven to rise and fall directly above the mixing cylinder.

[0014] This utility model provides a concrete vibration mixing device, which has the following beneficial effects: The device involves pouring concrete raw materials into the mixing drum, driving the stirring rod to rotate, mixing the materials with the stirring blades, and vibrating the raw materials inside the mixing drum with the vibrating rod to ensure uniform distribution of the various components of the concrete and eliminate air bubbles. By driving the reciprocating screw to rotate, the fixed seat moves back and forth, causing the slider to slide back and forth on the fixed seat, thereby uniformly vibrating the concrete inside the mixing drum and improving the quality of the concrete.

[0015] The device uses a connecting bevel gear and bevel gear ring to drive the reciprocating screw to rotate automatically as the fixed base rotates around the stirring rod, reducing the number of drive motors required. By starting the adjusting motor, the adjusting screw is driven to rotate, causing the entire mounting frame to rise and fall directly above the mixing cylinder. Attached Figure Description

A mixing cylinder 2 is fixedly connected to the fixed base 1, and a discharge pipe 21 is fixedly connected to the mixing cylinder 2. Concrete raw materials are poured into the mixing cylinder 2 in the specified proportion for mixing and stirring. The concrete is discharged from the mixing cylinder 2 by opening one end of the discharge pipe 21.

[0020] Please refer to it again. Figure 1 and Figure 2 The mounting frame 3 is equipped with a mixing mechanism and a vibration mechanism for mixing the concrete inside the mixing drum 2. The mixing mechanism includes a mixing rod 4 rotating at the bottom of the mounting frame 3. A mixing blade 5 is fixedly connected to the outer surface of the mixing rod 4. A mixing motor 41 that drives the mixing rod 4 to rotate is fixedly connected to the top of the mounting frame 3. A connecting groove is provided on the top of the mounting frame 3. The mixing rod 4 is driven to rotate by starting the mixing motor 41, and the material inside the mixing drum 2 is mixed and stirred by the mixing blade 5.

[0021] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The oscillation mechanism includes a vibrating rod 7. One end of the outer surface of the stirring rod 4 is fixedly connected to a fixed seat 6. A reciprocating screw 62 is rotatably connected inside the fixed seat 6. A slider 63 is sleeved on the reciprocating screw 62. The reciprocating screw 62 is a specially designed screw with a thread structure that allows the slider 63 to move not only axially when the screw rotates, but also to move back and forth without changing the rotation direction of the screw. The slider 63 usually has a nut structure, such as a ball nut or a sliding nut, that matches the screw thread for linear movement along the axial direction of the screw. This reciprocating mechanism is common knowledge in the art and will not be described in detail in this application. A bottom groove 61 is provided at the bottom of the fixed seat 6. One end of the slider 63 extends to the bottom of the fixed seat 6 through the bottom groove 61. The vibrating rod 7 is installed at the bottom of the slider 63. By driving the reciprocating screw 62 to rotate, the slider 63 is driven to slide back and forth inside the fixed seat 6, so that the vibrating rod 7 slides horizontally back and forth along the axial direction of the fixed seat 6. Example

[0022] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4One end of the fixed base 6 is fixedly connected to a vibrating host 71 connected to the vibrating rod 7. This vibration mechanism is a wireless lithium battery cement vibrating rod. It uses a lithium battery as a power source, freeing it from the constraints of traditional power cords. It has a built-in vibration motor, which generates centrifugal force through the high-speed rotation of the motor, causing the vibrating rod to vibrate at high frequency. The bottom of the slider 63 is provided with a fixing mechanism for fixing the vibrating rod 7. The fixing mechanism includes a connecting frame 72 fixed to the bottom of the slider 63. One end of the connecting frame 72 is detachably connected to a connecting clip 73 by bolts. The vibrating rod 7 is clamped between the connecting clip 73 and the connecting frame 72. One end of the connecting clip 73 and one end of the connecting frame 72 are provided with arc-shaped grooves. The connecting frame 72 and the connecting clip 73 are used to clamp one end of the vibrating rod 7.

[0023] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 One end of the reciprocating screw 62 extends to the outside of the fixed base 6. A connecting bevel gear 64 is fixedly connected to one end of the reciprocating screw 62. A bevel gear ring 8 is fixedly connected to the bottom of the mounting bracket 3. The connecting bevel gear 64 meshes with the bevel gear ring 8. The stirring rod 4 is located inside the bevel gear ring 8. When the fixed base 6 rotates around the stirring rod 4, the reciprocating screw 62 is driven to rotate under the meshing action of the bevel gear ring 8 and the connecting bevel gear 64. Example

[0024] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The top of the fixed base 1 is fixedly connected to two connecting seats 9, each of which has a sliding groove. The outer surface of the mounting frame 3 is fixedly connected to two sliding blocks 31. The two sliding blocks 31 slide inside the two sliding grooves respectively. Under the action of the sliding blocks 31 and the sliding grooves, the mounting frame 3 is stabilized above the mixing cylinder 2 and slides up and down.

[0025] Please refer to it again. Figure 1 A fixed slide rod 93 is fixedly connected inside one sliding groove, and a sliding block 31 is slidably connected to the outer surface of the fixed slide rod 93. An adjusting screw 91 is rotatably connected inside the other sliding groove, and another sliding block 31 is threadedly connected to the outer surface of the adjusting screw 91. An adjusting motor 92 that drives the adjusting screw 91 to rotate is fixedly connected to the top of the connecting seat 9. By starting the adjusting motor 92, the adjusting screw 91 is driven to rotate. Under the action of the sliding block 31, the mounting frame 3 moves up and down and slides between the two connecting seats 9.

[0026] Working principle: The concrete raw materials are poured into the mixing drum 2 according to the specified proportions. The adjusting screw 91 is driven to rotate by starting the adjusting motor 92. Under the action of the sliding block 31, the mounting frame 3 slides down between the two connecting seats 9, so that the mixing mechanism and the vibration mechanism at the bottom of the mounting frame 3 extend into the mixing drum 2. The mixing rod 4 is driven to rotate by starting the mixing motor 41. The mixing blade 5 mixes and stirs the materials inside the mixing drum 2. The vibrating host 71 is started to make the vibrating rod 7 vibrate to oscillate the materials inside the mixing drum 2, so that the various components of the concrete are evenly distributed and air bubbles are eliminated. The fixed seat 6 rotates with the rotation of the mixing rod 4. When the fixed seat 6 rotates around the mixing rod 4, the reciprocating screw 62 is driven to rotate inside the fixed seat 6 by the meshing action of the bevel gear ring 8 and the connecting bevel gear 64. This causes the slider 63 to move back and forth inside the fixed seat 6, and the vibrating rod 7 slides back and forth along the horizontal axis of the fixed seat 6 to oscillate the materials inside the mixing drum 2 evenly.
