However, traditional concrete floor leveling machines do not have automated operation capabilities and require full manual intervention. Full manual operation leads to high labor costs, construction efficiency is limited by personnel fatigue, and different operators make it difficult to unify the flatness. It also increases the labor intensity of workers and affects the construction quality and progress. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an automatic cement floor leveling machine, which solves the technical issues of high labor costs, low efficiency, difficulty in achieving uniform flatness, and high labor intensity caused by the requirement for manual operation of traditional cement floor leveling machines throughout the process.

[0004] The purpose and effect of this utility model of an automatic cement floor leveling machine are achieved by the following specific technical means: An automatic cement floor leveling machine includes a mounting frame and a control box. The mounting frame has a mounting platform, and the control box is mounted on the mounting platform. Two sets of assembly platforms are symmetrically arranged on the mounting frame on both sides of the mounting platform. Each set of assembly platforms is equipped with a drive motor, and both drive motors are electrically connected to the control box. Two sets of side wing plates are correspondingly arranged on the mounting frame on both sides of the drive motor. Each set of side wing plates has a connecting member inside, and a movable roller shaft is connected to the two sets of connecting members. Driven wheels are provided at both ends of the movable roller shaft, and the driven wheels on both sides of the movable roller shaft are connected to the shaft end of the drive motor via a transmission belt.

A spring is provided between the limiting member and the inner side of the side wing plate, and the spring is sleeved on the mounting column.

[0006] The above technical solution further includes that the vibrating plate is symmetrically provided with two sets of mounting holes, and the same set of vibrating rods are inserted into the two sets of mounting holes. When the vibrating rods are installed on the vibrating plate, the vibrating rods are detachably provided with fixing parts.

[0007] The above technical solution further includes that two sets of mounting parts are provided opposite to each other on the mounting frame between the two sets of vibrating plates, and a trowel blade is provided between the two sets of mounting parts.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example

[0019] like Figures 1 to 4As shown, this utility model provides an automatic cement floor leveling machine, including a mounting frame 1 and a control box 2. The mounting frame 1 has a mounting platform 101, and the control box 2 is mounted on the mounting platform 101. Two sets of assembly tables are symmetrically arranged on the mounting frames 1 on both sides of the mounting platform 101. Each assembly table is equipped with a drive motor 3, and both drive motors 3 are electrically connected to the control box 2. Two sets of side wing plates 102 are correspondingly provided on the mounting frames 1 on both sides of the drive motor 3. Each set of side wing plates 102 has a connecting piece 103, which connects to a moving roller shaft 4. Both ends of the moving roller shaft 4 have driven wheels 104, and the driven wheels 104 on both sides of the moving roller shaft 4 are connected to the shaft ends of the drive motor 3 via a transmission belt. A vibrating plate 105 is also detachably installed inside each set of side wing plates 102, and a vibrating motor 5 is mounted on the vibrating plate 105. An infrared sensor 106 is also provided on one side of each side wing plate 102. The control box 2 is fixed to the mounting frame 1 by the mounting platform 101 to ensure that it does not shift during operation. The control box 2 is electrically connected to the drive motor 3, and can directly transmit control signals to the drive motor 3 to realize the start, stop and speed adjustment of the drive motor 3, providing a control basis for the overall operation of the equipment, ensuring that the drive motor 3 works as required and avoiding erratic operation.

[0020] The drive motor 3 is mounted on two sides of the mounting bracket 1, each with two sets of side wing plates 102. Connectors 103 are installed within the side wing plates 102, connecting to the movable roller shaft 4. Driven wheels 104 are located at both ends of the movable roller shaft 4, connected to the shaft end of the drive motor 3 via a transmission belt. The side wing plates 102 provide a mounting surface for the connectors 103, ensuring stable fixation of the movable roller shaft 4 and guaranteeing its installation. When the drive motor 3 operates, power is transmitted to the driven wheels 104 via the transmission belt, causing the movable roller shaft 4 to rotate. This rotation of the movable roller shaft 4 enables the entire equipment to move without manual pushing, reducing manpower and improving equipment movement efficiency.

[0021] Two sets of side wing plates 102 are detachably fitted with vibrating plates 105, and vibrating motors 5 are mounted on the vibrating plates 105. The side wing plates 102 provide installation space for the vibrating plates 105, and the vibrating plates 105 are detachable. When the vibrating plates 105 or the vibrating motors 5 malfunction and require repair or replacement, the vibrating plates 105 can be quickly removed from the side wing plates 102, reducing repair difficulty and saving repair time. The vibrating motors 5 are mounted on the vibrating plates 105. When the vibrating motors 5 operate, they drive the vibrating plates 105 to vibrate, and the vibrating plates 105 contact the cement floor, realizing the vibration operation on the cement floor, increasing the density of the cement floor, and improving the quality of the floor.

[0022] An infrared sensor 106 is installed on one side of the side wing plate 102. The side wing plate 102 provides an installation position for the infrared sensor 106, enabling it to operate stably. The infrared sensor 106 can monitor obstacles in the direction of equipment movement. When the equipment approaches an obstacle such as a wall, the infrared sensor 106 can detect it in time and transmit a signal to the control box 2. After receiving the signal, the control box 2 controls the drive motor 3 to adjust its operation and change the direction of equipment movement, preventing the equipment from colliding with the wall during operation, protecting the equipment from damage, ensuring construction safety, and reducing equipment maintenance costs. The control box 2 can be a CP210 model control box; the infrared sensor 106 can be an IL-1000 model infrared distance sensor.

[0023] like Figures 1 to 3 As shown, the top of the vibratory tamping plate 105 has two sets of mounting columns 201 facing each other. The side wing plate 102 has a hollow structure. The two sets of mounting columns 201 of the vibratory tamping plate 105 are movably inserted into the side wing plate 102, and the top of the two sets of mounting columns 201 are detachably equipped with limiting members. A spring 202 is provided between the limiting member and the inner side of the side wing plate 102, and the spring 202 is sleeved on the mounting column 201. The vibratory tamping plate 105 has two sets of mounting columns 201 at its top, and the side wing plate 102 has a hollow structure, with the mounting columns 201 movably inserted into the side wing plate 102. This arrangement allows the vibratory tamping plate 105 to establish a connection with the side wing plate 102 through the mounting columns 201. The hollow structure provides space for the mounting columns 201 to pass through, while allowing the mounting columns 201 to have a certain amount of movement as the vibratory tamping plate 105 vibrates, ensuring that the vibratory tamping plate 105 does not rigidly collide with the side wing plate 102 during vibration operation, thus maintaining the stability of the vibration operation.

[0024] The top of the mounting column 201 is equipped with a detachable limiting component. This limiting component restricts the range of motion of the mounting column 201 within the side wing plate 102, preventing the vibrating plate 105 from detaching from the side wing plate 102 due to excessive vibration amplitude, and ensuring the stability of the connection between the vibrating plate 105 and the side wing plate 102. The detachable structure facilitates quick removal of the limiting component and detachment of the vibrating plate 105 when it needs maintenance or replacement, reducing disassembly and assembly difficulty and saving maintenance time.

[0025] A spring 202 is provided between the limiting component and the inner surface of the side wing plate 102, and the spring 202 is fitted onto the mounting post 201. The spring 202 can absorb the impact force generated by the vibration of the vibrating plate 105, reduce the force of vibration transmitted to the side wing plate 102 and the mounting frame 1, and prevent the mounting frame 1 from becoming loose or damaged due to long-term vibration. At the same time, the elasticity of the spring 202 can assist the mounting post 201 in resetting, ensuring that the vibrating plate 105 can return to its initial working position after vibration, and maintain the consistency of the vibration operation.

[0026] The vibrating plate 105 has two sets of symmetrical mounting holes, through which the same set of vibrating rods 301 are inserted. When the vibrating rods 301 are installed on the vibrating plate 105, a detachable fixing component is provided on the vibrating rods 301. The vibrating plate 105 has two sets of symmetrical mounting holes, through which the vibrating rods 301 pass. This arrangement allows the vibrating rods 301 to form a stable connection with the vibrating plate 105 through the mounting holes. The symmetrical layout ensures that the vibrating rods 301 are subjected to uniform force, preventing them from shifting due to force imbalance during vibration operation, ensuring that the vibrating rods 301 are always in the preset working position, and improving the stability of the vibration operation. The vibrating rods 301 are equipped with detachable fixing components. These fixing components can fix the vibrating rods 301 in the mounting holes, preventing them from coming out during vibration and ensuring continuous vibration operation. The detachable design allows for the replacement of different specifications of the vibrating rod 301 according to the vibration requirements of the cement floor, improving the equipment's adaptability to different construction scenarios.

[0027] The combination of detachable fasteners and through-mounting facilitates the assembly and disassembly of the vibratory rod 301. When the vibratory rod 301 shows signs of wear or malfunction, the fasteners can be quickly removed, and the vibratory rod 301 can be taken out for repair or replacement without disassembling the entire vibratory plate 105, reducing maintenance difficulty, minimizing equipment downtime, and ensuring construction progress.

[0028] like Figure 2 As shown, the mounting frame 1 between the two sets of vibrating plates 105 has two sets of mounting parts facing each other, and a trowel blade 401 is provided between the two sets of mounting parts. Mounting rods are provided on both sides of the trowel blade 401, and the trowel blade 401 is rotatably mounted within the mounting part via the mounting rods. The rotation direction of the trowel blade 401 is consistent with the rotation direction of the two sets of moving rollers 4. The mounting frame 1 between the two sets of vibrating plates 105 has two sets of facing mounting parts, and mounting rods are provided on both sides of the trowel blade 401, which are rotatably connected to the mounting parts via the mounting rods. This arrangement allows the trowel blade 401 to establish a stable assembly relationship with the mounting part through the mounting rods. The mounting part provides support for the mounting rods, ensuring that the trowel blade 401 does not shift during rotation, maintaining the stability of the troweling operation. At the same time, the rotatable connection method meets the movement requirements of the trowel blade 401 during operation, ensuring smooth troweling action.

[0029] The rotation direction of the trowel blades 401 is consistent with the rotation direction of the two sets of moving rollers 4. The rotation of the moving rollers 4 drives the entire equipment to move, and the trowel blades 401 rotate synchronously in the same direction, matching the troweling action of the trowel blades 401 with the movement direction of the equipment. This avoids messy troweling marks on the ground due to directional differences, ensuring a uniform texture after troweling, improving the surface smoothness, eliminating the need for additional post-processing, and reducing construction steps. The trowel blades 401 are positioned between the two sets of vibrating plates 105. The vibrating plates 105 first vibrate the cement ground to make it dense, and then the trowel blades 401 immediately follow with the troweling operation, achieving a continuous connection between the vibration and troweling processes. This eliminates the need for separate operations in stages, shortening construction time and improving overall construction efficiency. Simultaneously, this layout allows the trowel blades 401 to directly act on the vibrated ground, preventing surface drying due to prolonged exposure after vibration, ensuring a smooth troweling effect.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the side wing plate 102 has two sets of mounting holes. A connector 103 passes through one set of mounting holes, and an arc-shaped baffle 501 passes through the other set of mounting holes. The arc-shaped opening of the baffle 501 corresponds to an adjacent set of driven wheels 104. The two sets of mounting holes in the side wing plate 102, with the connector 103 passing through one set, provide an installation channel for the connector 103, ensuring a stable connection between the connector 103 and the side wing plate 102, thereby fixing the moving roller shaft 4 and preventing it from loosening during equipment operation. The structure of the two sets of mounting holes also reserves installation space for subsequent additions of components, improving the functional expandability of the side wing plate 102 without requiring additional holes in it, thus simplifying the structural processing flow.

[0031] Another set of mounting holes is fitted with an arc-shaped baffle 501, the arc-shaped opening of which corresponds to the driven wheel 104. The arc-shaped structure conforms to the shape of the driven wheel 104, expanding the coverage area of ​​the baffle 501 on the driven wheel 104. This prevents cement debris, dust, and other debris from contacting the driven wheel 104, avoiding debris from getting tangled in the driven wheel 104 or stuck in the transmission parts, preventing the driven wheel 104 from being obstructed from rotating, ensuring the transmission efficiency between the transmission belt and the driven wheel 104, and reducing equipment failures. The baffle 501 is mounted on the side wing plate 102 through the mounting holes, sharing the installation space of the side wing plate 102 with the connecting piece 103. This layout makes the baffle 501 and the connecting piece 103 compactly distributed on the side wing plate 102, without occupying additional external space, and avoiding interference between the baffle 501 and other components during equipment operation. At the same time, the mounting hole installation method facilitates the disassembly and assembly of the baffle 501. When the baffle 501 is worn or damaged, it can be quickly removed and replaced, reducing maintenance difficulty.

[0032] like Figure 1 and Figure 4 As shown, a wire trough 601 is provided between the two sides of the mounting platform 101 and the two assembly platforms, and a detachable cover 602 is provided on the wire trough 601. The wire trough 601 provides dedicated space for the internal wiring of the equipment, allowing the connecting wires between the control box 2 and the drive motor 3, etc., to be centrally arranged within the wire trough 601, preventing the wires from being scattered, tangled in the moving parts of the equipment, or damaged by compression, thus ensuring stable circuit connections. The detachable cover 602 covers the wire trough 601, preventing dust, cement debris, etc., from entering the trough and contaminating or damaging the wires, thus protecting them. The detachable structure allows for quick opening of the cover 602 for operation when the wiring needs to be inspected, replaced, or new lines added, without damaging the structure of the wire trough 601, simplifying the wiring maintenance process.

[0033] The cable tray 601 and the tray cover 602 work together to make the internal wiring layout of the equipment neat and orderly. This not only reduces the probability of wiring failure, but also makes it easier for construction personnel to quickly identify the wiring connections. When circuit problems occur in the equipment, the fault point can be located, shortening the troubleshooting and repair time and ensuring the continuous and stable operation of the equipment.

[0034] Mounting frame 1 is made of I-beam steel, and its outer surface is coated with an epoxy anti-rust coating. Multiple sets of moving rollers 4 have spirally arranged raised ribs 701 on their outer surfaces. The I-beam steel structure itself has strong load-bearing capacity, supporting the weight of components such as the control box 2 and drive motor 3, preventing deformation of the mounting frame 1 due to excessive force, ensuring the overall stability of the equipment structure, maintaining the relative positions of each component, and ensuring normal operation. The epoxy anti-rust coating on the outer surface of mounting frame 1 isolates air and moisture from contact with the surface of mounting frame 1, preventing corrosion from moisture and cement slurry in the construction environment, extending the service life of mounting frame 1, reducing equipment failures caused by corrosion, and lowering maintenance costs.

[0035] The outer surface of the movable roller 4 is provided with a spiral protrusion 701. The protrusion 701 can increase the friction between the movable roller 4 and the cement ground, prevent the equipment from slipping when moving on the cement ground, and ensure that the equipment moves stably in the preset direction. At the same time, the spiral structure can help disperse the cement material on the ground and improve the leveling effect of the ground.

[0036] The above description is merely an embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
