[0002] Concrete is easy to use, quick to use, and low in cost, making it widely used in engineering construction. After the concrete is poured, it needs to be smoothed. Existing smoothing tools are inconvenient to move because their bottom structures are in direct contact with the ground. Therefore, a grouting and smoothing tool for pouring a concrete protective layer is proposed. Utility Model Content
[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a grouting and smoothing tool for pouring a concrete protective layer.
[0004] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solutions, including a mounting frame, in which a motor for driving is installed, an adjusting armrest is added to the outside of the mounting frame, a support frame is provided under the mounting frame, the surface of the support frame is provided with four locking holes at positions far away from each other, the inner wall of the locking hole is provided with a thread, and universal wheels for movement are inserted and fixed inside the four locking holes, and the support frame moves on the ground through the four universal wheels, and four connecting sockets at positions far away from each other are provided on the chassis frame of the mounting frame, and four connecting columns at positions symmetrical to each other are fixedly installed on the surface of the support frame, and the top surface of the connecting column is provided with a thread, and the outer diameter of the connecting column corresponds to the inner size of the connecting socket, and the support frame is restricted and installed under the chassis frame of the mounting frame by the four connecting columns.
[0005] Furthermore, the outside of the connecting column is provided with an adjusting collar 1 and an adjusting collar 2, and the adjusting collar 2 is located above the connecting socket. After the connecting column is inserted into the connecting socket, the position is fixed by the adjusting collar 1 and the adjusting collar 2.
[0006] Furthermore, a connecting chuck with a cross structure is fixedly mounted on the motor output shaft of the mounting frame, and fixing holes are provided inside the four corners of the connecting chuck.
[0007] Furthermore, a trowel plate for smoothing concrete is provided on the outside of the connecting chuck. The trowel plate is an arc plate structure with upturned sides. A clamping column is fixedly installed at one end of the trowel plate corresponding to the fixing hole.
[0008] Furthermore, a threaded hole connected to the outside of the connecting chuck is opened inside the fixing hole, and a through hole corresponding to the size of the threaded hole is opened inside the clamping column. The clamping column is inserted into the fixing hole and locked by a bolt.
[0009] The utility model provides a grouting and troweling tool for pouring a concrete protective layer, which has the following beneficial effects:
[0010] After the four universal wheels are in contact with the ground, the entire device can be pushed to move on the road surface by adjusting the handrail, so that the entire device can be transferred easily.
[0011] 2. A grouting and smoothing tool for pouring a concrete protective layer is provided with a trowel plate with a special-shaped structure. The overall structure of the trowel plate is an inverted T-shape with both sides tilted upward. After inserting the clamping column fixed at the tail end of the trowel plate into the inside of the fixing hole, insert the fixing bolt into the threaded hole and pass it through the inside of the clamping column to complete the locking. Then, the connecting chuck is fixedly installed under the motor drive shaft installed inside the mounting frame and connected and fixed. When the entire device is in operation, the connecting chuck pulls the four trowel plates to perform circular motion. Since both sides of the trowel plate are tilted structures, they will generate downward pressure on the raised road surface during the contact with the concrete surface, making the road surface passed by the device smoother. Concrete will not be pulled and splashed during the leveling process, which greatly improves the smoothing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] A grouting and troweling tool for pouring concrete cover, such as Figures 1 to 3 As shown, it includes a mounting frame 1, in which a motor for driving is installed, an adjustable armrest 2 is added to the outside of the mounting frame 1, and a support frame 5 is arranged below the mounting frame 1. The surface of the support frame 5 is provided with four locking holes 6 at positions far away from each other, and the inner wall surface of the locking hole 6 is provided with a thread, and universal wheels 7 for movement are inserted and fixed inside the four locking holes 6. The support frame 5 moves on the ground through the four universal wheels 7, and four connecting sockets 10 at positions far away from each other are provided on the chassis frame of the mounting frame 1. Four connecting columns 8 at positions symmetrical to each other are fixedly installed on the surface of the support frame 5, and the top surface of the connecting column 8 is provided with a thread and the outer diameter size corresponds to the inner size of the connecting socket 10. The support frame 5 is restricted and installed below the chassis frame of the mounting frame 1 by the four connecting columns 8.
[0019] The outside of the connecting column 8 is provided with an adjusting collar 9 and an adjusting collar 11. The adjusting collar 11 is located above the connecting socket 10. After the connecting column 8 is inserted into the inside of the connecting socket 10, the adjusting collar 9 and the adjusting collar 11 are respectively located on the lower and upper sides of the chassis of the mounting frame 1. By rotating and adjusting the positions of the adjusting collar 9 and the adjusting collar 11, the distance between the chassis of the mounting frame 1 and the supporting frame 5 can be controlled. When the supporting frame 5 descends to the point where the four universal wheels 7 are in contact with the ground, the entire device can be moved and adjusted on the ground, and can be conveniently moved to the area where construction is required.
[0020] A cross-shaped connecting chuck 3 is fixedly installed on the motor output shaft of the mounting frame 1, and fixing holes 12 are provided inside the four corners of the connecting chuck 3. A trowel plate 4 for smoothing the concrete is provided on the outside of the connecting chuck 3. The trowel plate 4 is an arc plate structure with upturned sides. A clamping column 14 is fixedly installed on one end of the trowel plate 4 corresponding to the fixing hole 12. A threaded hole 13 connected to the outside of the connecting chuck 3 is provided inside the fixing hole 12, and a through hole corresponding to the size of the threaded hole 13 is provided inside the clamping column 14. The clamping column 14 is inserted into the inside of the fixing hole 12 and locked by bolts.
[0021] The working principle of this utility model:
[0022] After the jack is lifted up, the four universal wheels 7 are in contact with the ground, and the whole device can be pushed to move on the road surface by adjusting the handrail 2.
[0023] By providing a trowel plate 4 with a special-shaped structure, the overall structure of the trowel plate 4 is an inverted T-shape with both sides tilted upward. After inserting the clamping column 14 fixed at the tail end of the trowel plate 4 into the interior of the fixing hole 12, insert the fixing bolt into the threaded hole 13 and pass through the interior of the clamping column 14 to complete the locking. Then, the connecting chuck 3 is fixedly installed under the motor drive shaft installed inside the mounting frame 1 and connected and fixed. When the entire device is in operation, the connecting chuck 3 pulls the four trowel plates 4 to perform circular motion. Since both sides of the trowel plate 4 are tilted structures, downward pressure will be generated on the raised road surface during contact with the concrete surface, making the road surface passed by the device smoother. Concrete will not be pulled and splashed during the leveling process, which greatly improves the leveling efficiency.
