Description

Technical Field

[0001] The present application relates to the field of concrete construction, and in particular to a concrete leveling device. Background Art

[0002] When pouring concrete, factors such as vibration and aggregate sinking will cause the concrete surface to become uneven. At this time, concrete leveling is required to ensure the surface flatness. During the leveling process, it is necessary to pay attention to controlling the strength and direction of the leveling machinery to avoid causing excessive pressure or damage to the poured concrete.

[0003] Application No. 202320784132.2 discloses a concrete leveling device, including a connecting base plate, a trowel plate, a horizontal cotton, an inclined plate and a leveling roller, etc. The concrete is leveled by a trowel plate arranged at the bottom of the connecting base plate, and the trowel plate is connected to the connecting base plate through the action of a connecting plate and a fixing nail, so as to facilitate the installation and disassembly of the trowel plate. Through the action of the set auxiliary leveling mechanism, when the user pushes the trowel plate at the bottom of the connecting base plate to level the concrete, the leveling roller on the auxiliary leveling mechanism can be driven to roll at the same time, thereby realizing secondary leveling. At the same time, the height of the leveling roller can be adjusted according to actual conditions to adapt to the leveling work on the concrete in different situations. The adjusting pushing mechanism cooperates with the pushing handle to not only facilitate the pushing of the disturbing plate, but also can be appropriately adjusted according to the height of the user. The device of the present application has a simple structure, which is not only convenient for the installation and replacement of the trowel plate, but also can perform secondary auxiliary leveling work to ensure the flatness of the concrete.

[0004] However, in use, there are the following defects:

[0005] Although a trowel plate and a leveling roller are used to achieve secondary leveling of the concrete, the lack of a filling mechanism causes honeycombed surfaces on the concrete surface, and the adjustment and pushing mechanism of the device is not convenient for driving the trowel plate and the leveling roller to turn. Forced turning may make the concrete uneven, thus affecting the practicality of the device. Utility Model Content

[0006] The purpose of the present application is to provide a concrete smoothing device, which solves the problem raised in the background technology that although a trowel plate and a leveling roller are used to achieve secondary smoothing of the concrete, the lack of a filling mechanism causes honeycombed surfaces to appear on the surface of the concrete, and the adjustment and pushing mechanism of the device is not convenient for driving the trowel plate and the leveling roller to turn. If a turn is forced, the concrete may become uneven, thereby affecting the practicability of the device.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a concrete smoothing device, comprising a smoothing disk, a center hole, a telescopic rod, an adjusting bolt and a fixing bolt, a center hole is opened in the center of the top of the smoothing disk, and support columns are fixedly installed on the top of the smoothing disk on both sides of the center hole, and the top of the support column is fixedly connected to the two sides of the bottom of the storage tank, and the bottom of the storage tank is evenly fixedly connected and connected to a plurality of discharge pipes, and connecting rods are also fixedly installed on the top of the smoothing disk on both sides of the center hole, and a cross bar is fixedly installed on the top of the connecting rod, and the direction of the cross bar is perpendicular to the direction of the storage tank.

[0008] In this technical solution, the handle is held to drive the telescopic rod and the smoothing disk to smooth the surface of the concrete. The adjusting hole on the telescopic rod can be adjusted in length by the adjusting bolt. The smoothing disk is set to be circular and the edge is set to be arc-shaped, so that the flatness of the concrete will not be damaged during smoothing. The filling liquid can be added in the process of smoothing through the storage tank, the center hole and the discharge pipe. The filling liquid is pre-filled into the storage tank. During the smoothing process, a honeycomb surface will appear. At this time, the filling liquid in the storage tank is discharged from the center hole to the concrete surface through the discharge pipe. Then, no matter which direction the smoothing disk moves, the concrete can be smoothed for a second time, thereby improving the smoothing efficiency. The smoothing direction can be quickly changed through the turntable, the fixing plate, the fixing bolt and the telescopic rod. The turntable can be rotated at will. When the smoothing direction needs to be changed, the handle can be directly held to drive the telescopic rod to move without moving the smoothing disk, thereby reducing the stirring of the concrete caused by the tilt that may occur during the movement of the smoothing disk, thereby improving the practicality and smoothing efficiency of the device.

[0009] As an optional solution of the technical solution of the present application, a turntable is fixedly installed at the center of the top end of the crossbar, and two fixing plates are fixedly connected to the top end of the turntable.

[0010] As an optional solution of the technical solution of the present application, the bottom of the telescopic rod is located between the two fixing plates, and the fixing bolts are transversely connected to the fixing plates and the telescopic rod through threads from the outer side walls of the fixing plates.

[0011] As an optional solution of the technical solution of the present application, a handle is fixedly connected to the top of the telescopic rod, a plurality of adjustment holes are evenly opened on the side wall of the telescopic rod, and the adjustment bolt is connected to the telescopic rod thread through the adjustment hole.

[0012] As an optional solution of the technical solution of the present application, a baffle is fixedly installed on the outer edge of the top end of the smoothing disk.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present application uses a storage tank, a center hole and a discharge pipe to add filling liquid during the smoothing process. The filling liquid is pre-filled into the storage tank. During the smoothing process, a honeycombed surface will appear. At this time, the filling liquid in the storage tank is discharged from the center hole to the concrete surface through the discharge pipe. Then, no matter which direction the smoothing disc moves, the concrete can be smoothed for a second time, thereby improving the smoothing efficiency.

[0015] 2. The present application can quickly change the direction of smoothing through a turntable, a fixed plate, a fixing bolt and a telescopic rod. The turntable can be rotated at will. When the direction of smoothing needs to be changed, the telescopic rod can be moved directly by holding the handle without moving the smoothing disc, thereby reducing the stirring of concrete caused by the tilting of the smoothing disc during movement, thereby improving the practicality and smoothing efficiency of the device.

The direction of the cross bars 12 is perpendicular to the direction of the storage tank 8, and the storage tank 8 can store filling liquid in advance.

[0024] like Figure 1 and Figure 2 As shown, support columns 7 are fixedly installed on the top of the leveling plate 1 on both sides of the center hole 10, and the top of the support column 7 is fixedly connected to the two sides of the bottom of the storage tank 8, and the bottom of the storage tank 8 is evenly fixedly connected and connected with a plurality of discharge pipes 9, which are opposite to the center hole 10 and can fall onto the surface of the concrete through the center hole 10 during discharge.

[0025] like Figure 3 As shown, a turntable 13 is fixedly installed at the center of the top of the cross bar 12, and two fixing plates 14 are fixedly connected to the top of the turntable 13.
