[0002] In the field of civil engineering, a concrete trowel is a device commonly used for concrete surface treatment. Its main function is to smooth the concrete surface to ensure its flatness and smoothness. Existing concrete trowels usually use a rotating disc and a scraper system to complete this task. However, there are some problems with the existing technical solutions, especially in terms of the uniformity of the trowel and the convenience of equipment maintenance.

[0003] In actual applications, existing concrete trowel machines often face the following major problems: even if the equipment can perform troweling effectively, the troweling effect on the concrete surface is often uneven due to the unadjustable scraper angle and the difficulty in assembling and disassembling the equipment, and the equipment maintenance and component replacement process are complicated.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 - Figure 5 As shown, a civil engineering concrete trowel machine comprises a processing disk 1 and a driving motor 101 on the top of the processing disk 1, a control handrail 103 is installed on one side of the top of the processing disk 1, a detachable rotating base is arranged at the bottom of the processing disk 1, a mesh cover 102 is connected to the bottom of the processing disk 1, the rotating base is located inside the mesh cover 102, a circle of detachable smear scrapers are arranged around the rotating base, and a limit rod assembly that can slide up and down is arranged between the rotating base and the smear scraper.

[0029] The rotating base includes a turntable 2 and a docking threaded tube 6 on the top of the turntable 2. The output shaft of the driving motor 101 passes through the processing disk 1 and extends downward to the inside of the docking threaded tube 6. The outer side of the docking threaded tube 6 is threadedly connected with a circle of first fixing bolts 601. The output shaft of the driving motor 101 and the docking threaded tube 6 are fixed by the first fixing bolts 601. There are at least three groups of first fixing bolts 601 on the outer side of the docking threaded tube 6. The first fixing bolts 601 are threadedly connected to the docking threaded tube 6 and are arranged along its radial direction. The bottom of the turntable 2 is connected with a sliding disk 4. By providing the docking threaded tube 6, the first fixing bolts 601, the turntable 2 and the driving motor 101, the rotating base at the bottom of the processing disk 1 can be detachably connected, which is convenient for disassembly and assembly.

[0030] A plurality of mounting grooves 201 are provided around the side of the turntable 2 , and at least two sets of limit rod assemblies are vertically installed inside each mounting groove 201 .

[0031] The scraper includes a connecting plate 5 and a scraper plate body 3 obliquely connected to the outside of the connecting plate 5, the angle between the scraper plate body 3 and the connecting plate 5 is between 90 degrees and 180 degrees, the connecting plate 5 is an L-shaped structure, and the scraper plate body 3 is slidably connected to the second fixing bolt 501 extending from the connecting plate 5, the second fixing bolt 501 is threadedly connected to the connecting plate 5, and the scraper plate body 3 and the connecting plate 5 are fixed by the second fixing bolt 501. The inclination angle of the scraper plate body 3 on the outside of the connecting plate 5 can be adjusted according to needs, and the angle between the scraper plate body 3 and the connecting plate 5 can be adjusted. When a scraper plate body 3 is damaged, the corresponding second fixing bolt 501 can be removed for replacement and maintenance.

[0032] The limiting rod assembly includes two groups of connecting rods 202 located inside the mounting groove 201 and two groups of springs 203 sleeved on the outside of each connecting rod 202. One end of the connecting plate 5 slides into the mounting groove 201. The connecting plate 5 is slidably connected to the two connecting rods 202. The two groups of springs 203 outside each connecting rod 202 are respectively located on the upper and lower sides of the connecting plate 5.

[0033] The driving motor 101 drives the turntable 2 to rotate, and at this time, the inclined scraper plate body 3 is driven to rotate through the connecting plate 5 connected to the installation groove 201. In the process of the scraper plate body 3 rotating and smoothing the ground concrete, when the scraper plate body 3 collides with the stone in the concrete, the scraper plate body 3 will drive the connecting plate 5 to slide on the two sets of limit rod assemblies due to the collision. The upper and lower sets of springs 203 on the connecting rod 202 will shrink and extend one at a time. When the scraper plate body 3 leaves the stone, the spring 203 on the connecting rod 202 will drive the scraper plate body 3 to shrink and adjust up and down through its own elastic force, which can avoid the scraper plate body 3 from colliding with the stone or debris in the concrete to cause the side to collapse and produce a gap, reduce the mechanical damage caused by the collision with the gravel, and maintain the service life of the scraper plate body 3.

[0034] like Figure 4-Figure 5 As shown, the turntable 2 in the present technical solution is a hexagonal structure, so the outer side of the turntable 2 is provided with six groups of smear scrapers, and when the rotating base rotates one circle, the concrete on the bottom surface of the corresponding processing disk 1 will be rotated and smoothed six times.

[0035] Through the cooperation of a rotating base and multiple sets of trowel scrapers, the trowel machine can efficiently and evenly smooth the concrete surface.

[0036] The hexagonal structure of the turntable 2 and the six sets of trowels ensure that the troweling work on the concrete surface is evenly processed at every position. The rotation of the rotating base causes the trowels to rotate on the concrete surface, thereby completing the comprehensive troweling work.

[0037] The inclination angle of the scraper plate body 3 is adjustable, and the angle of the scraper plate body 3 can be adjusted according to specific needs to improve the flexibility and adaptability of the trowel effect.

[0038] The angle between the scraper blade body 3 and the connecting plate 5 can be adjusted by the second fixing bolt 501. The adjustment of the angle can make the working angle of the scraper blade body 3 better adapt to different concrete surface conditions.

[0039] When the scraper collides with stones or debris in the concrete, the edge of the scraper body 3 can be prevented from breaking or notching, thereby extending the service life.

[0040] The design of the spring 203 of the limit rod assembly enables the connection plate 5 to slide on the connection rod 202 when the scraper plate body 3 collides with a stone, and the spring 203 provides elastic force to return the scraper plate body 3 to a normal position after the collision. This design reduces the mechanical damage to the scraper plate body 3 caused by the collision and ensures the durability of the scraper plate body 3.

[0041] The detachable design of the rotating base makes the maintenance and parts replacement of the entire trowel machine easy.

[0042] The cooperation between the butt threaded tube 6 and the first fixing bolt 601 allows the rotating base to be quickly connected and disconnected with the rotating base at the bottom of the processing disk 1. This design allows the user to quickly disassemble and replace parts, thereby improving the maintenance efficiency of the equipment.

[0043] Due to the hexagonal design of the turntable 2 and the use of multiple trowel blades, the trowel machine can achieve six comprehensive troweling on the concrete surface, thereby improving the uniformity and coverage of the troweling.

[0044] The spring 203 not only protects the scraper body 3, but also reduces the impact of the machine on the concrete surface during operation, and can maintain the consistency and smoothness of the concrete surface.

[0045] With the easily detachable rotating base design and the adjustable 3 angles of the scraper plate body, users can easily adjust and handle the equipment according to different work needs and maintenance requirements, greatly simplifying the operation process and maintenance work.

[0046] Due to the adjustability of the 3-angle blade body and the buffer design, the trowel can adapt to different types of concrete conditions, including concrete with uneven surfaces or containing large particles.

[0047] In summary, this technical solution achieves efficient and uniform concrete finishing through the coordination of the turntable 2, the rotating base, the trowel blade and the limit rod assembly. Its design takes into account the service life of the equipment, the convenience of maintenance and the ability to adapt to different working environments. The detailed structural design and effect analysis not only ensure the quality of finishing, but also improve the efficiency of the equipment.
