Description

Technical Field

[0001] The utility model relates to the field of construction tools, in particular to a ground leveling device. Background Technique

[0002] With the increasing improvement of people's production and living standards, when hardening the indoor and outdoor ground, it is necessary to lay cement. Since the cement is in a slurry-like flowing state during laying, the laid ground is uneven, and there is still air in the cement, resulting in low density of the cement. Manual compaction and leveling operations are required. Currently, for the compaction and leveling of cement mortar floors, workers usually use a scraper to repeatedly press and smear to level the ground. Workers need to squat down to operate, with high labor intensity and low efficiency. In order to prevent the cement from cracking and increase durability after leveling, it is also necessary to manually lay a layer of film on the surface of the cement, which greatly affects work efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide a ground leveling device to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A ground leveling device includes a main operating rod. A handle is provided at the top of the main operating rod. A power supply box is fixedly installed in the middle of the main operating rod. The power supply box is connected to a motor through a power cord. A flattening plate is installed below the side of the motor. A support rod is provided above the top surface of the flattening plate. A film cylinder is provided on the support rod.

[0006] Preferably, a power switch is provided on the power supply box, and the power switch is used to adjust the switch and vibration frequency of the motor.

[0007] Preferably, an eccentric wheel is installed at the end of the motor shaft, and the motor is fixedly installed between the main operating rod and the flattening plate through a base.

[0008] Preferably, one side edge of the flattening plate near the motor has a certain arc and is warped, the bottom surface of the pressing plate is flat, and the top surface of the pressing plate is connected to the support rod through a bracket.

[0009] Preferably, U-shaped openings are provided at both sides of the support rod near one end of the film cylinder. After the U-shaped openings are clamped into the central axis, they are threadedly connected through a wing nut.

[0010] Preferably, a battery pack is provided inside the power supply box.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] For this ground leveling device, the operator first places the leveling device on the cement surface. By turning on the power switch, the motor starts to vibrate, driving the flattening plate to vibrate. Then, the operator drags the leveling device towards the handle direction. During the vibration process, the air in the cement gaps is squeezed out, and the cement surface is flattened. This device is easy to operate, saves manpower, and increases work efficiency.

[0013] For this ground leveling device, through the combination of a support rod, a U-shaped opening, a wing nut, a film tube, and a central shaft, after flattening, the film can be directly laid on the flattened cement surface, which plays a role in preventing cracking and increasing durability. This operation is convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1 - Figure 2 As shown, a technical solution provided by the present utility model:

[0019] A ground leveling device includes a main body 1 of the operating rod. A handle 10 is provided at the top of the main body 1 of the operating rod. A power supply box 2 is fixedly installed in the middle of the main body 1 of the operating rod. The power supply box 2 is connected to a motor 301 through a power cord 202. A flattening plate 4 is installed below the side of the motor 301. A support rod 5 is provided above the top surface of the flattening plate 4. A film tube 7 is provided on the support rod 5.

[0020] In this embodiment, preferably, a power switch 201 is provided on the power supply box 2. The power switch 201 is used to adjust the switch of the motor 301 and adjust the vibration frequency of the motor by rotating the amplitude of the power switch 201.

[0021] In this embodiment, preferably, an eccentric wheel 302 is installed at the shaft end of the motor 301. After the power switch 201 is turned on, the motor 301 starts to rotate, generating vibrations by driving the eccentric wheel 302. The motor 301 is fixedly installed between the operating rod main body 1 and the flattening plate 4 through the base 3.

[0022] In this embodiment, preferably, one side edge of the flattening plate 4 near the motor 301 has a certain arc-shaped upward curvature to prevent cement from getting stuck on the flattening plate 4 during operation. The bottom surface of the pressing plate 4 is flat, and the top surface of the flattening plate 4 is connected to the support rod 5 through the bracket 6.

[0023] In this embodiment, preferably, U-shaped openings 501 are provided at both sides of the support rod 5 near one end of the film cylinder 7. After the central shaft 9 is inserted into the U-shaped openings 501, it is tightly connected by screwing the wing nut 8.

[0024] In this embodiment, preferably, a battery pack is provided inside the power supply box 2.

[0025] When the leveling device of this embodiment is in use, first unscrew the wing nut 8, then the central shaft 9 can be removed. Put the film cylinder 7 onto the central shaft 9, then insert the central shaft 9 into the U-shaped openings 501 at both ends of the support rod 5. Finally, screw the wing nuts at both ends onto the central shaft 9 and tighten them on the support rod 5. Pull out a part of the film from the film cylinder 7 and attach it to the cement on the ground. Turn on the power switch 201, the motor 301 starts to rotate, drives the eccentric wheel 302 to rotate, generates an amplitude, drives the flattening plate 4 to vibrate, and then starts to compact and level the cement under the bottom surface of the flattening plate 4. The operator holds the handle 10 and drags it backward, then the whole leveling device can move backward to level the flatness of the cement surface. At the same time, as the film cylinder 7 rotates following the movement of the leveling device, the flattened cement is covered with the film. This device is simple to operate, saves labor, and completes the compaction, leveling, and film covering work at one time.
