[0003] In existing technology, concrete finishing is typically performed using a finishing device. Its main structure consists of a drive motor that rotates a number of radially distributed finishing rods to finish the concrete surface. The finishing device is then dragged and moved by construction workers. Because the finishing rods rotate during the finishing process, the finishing device's direction of travel can easily deviate, making it difficult to control and prone to uneven finishing. This requires finishing work by construction workers, which not only affects the quality of the finished concrete, but also increases labor input. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0025] like Figures 1 to 3 As shown, a concrete finishing device includes:

[0026] Base plate 1;

[0027] The moving motor 2 is horizontally arranged on the upper surface of one end of the base plate 1, and the output shaft is connected to the vertical moving wheel 3; the lower half of the vertical moving wheel 3 passes through the base plate 1;

[0028] The plastering motor 4 is vertically downwardly arranged above the other end of the base plate 1, and the output shaft is fixed with a driving gear 5;

[0029] A first rotating shaft 6 is rotatably mounted on the bottom plate 1 next to the driving gear 5. A first driven gear 9 is provided on the top thereof, meshing with the driving gear 5. The bottom thereof passes through the bottom plate 1 and is connected to the center of a horizontal wiping plate 7. The horizontal wiping plate 7 has a plurality of wiping rods 8 extending radially outward.

[0030] The second rotating shaft 10 is also provided on the bottom plate 1 next to the driving gear 5, and a second driven gear 11 is provided on the top thereof to mesh with the driving gear 5;

[0031] The third rotating shaft 12 is rotatably mounted on the base plate 1 next to the second driven gear 11. A third driven gear 121 is provided on the top thereof, meshing with the second driven gear 11. The bottom thereof passes through the base plate 1 and is connected to the center of another horizontal wiping plate 7. The horizontal wiping plate 7 also has a plurality of wiping rods 8 extending radially outward. The wiping rods 8 at the bottom of the first rotating shaft 6 and the third rotating shaft 12 are initially interlaced with each other.

[0032] In the present invention, the main working process is as follows: by starting the moving motor 2, the vertical moving wheel 3 is driven to rotate, thereby driving the bottom plate 1 as a whole to move on the concrete surface, completing the pulling process of the vehicle body. During the pulling process of the present invention device, the plastering motor 4 is synchronously started, and the plastering motor 4 drives the driving gear 5 to rotate, and then the first driven gear 9 engaged with the driving gear 5 drives the first rotating shaft 6 to rotate, and synchronously drives the horizontal wiping plate 7 to rotate, realizing the rotation of the first horizontal wiping plate 7 and the first set of wiping rods 8; because the other side of the driving gear 5 is also engaged with the second driven gear 11, when the second driven gear 11 rotates, it will drive the third driven gear 121 at the top of the third rotating shaft 12 engaged with the second driven gear 11, thereby driving the other set of wiping rods 8 / another horizontal wiping plate 7 at the bottom of the third rotating shaft 12 to rotate according to the same principle. Because the third rotating shaft 12 is driven to rotate by the second driven gear 11, the rotation direction of the third rotating shaft 12 is ensured to be opposite to that of the first rotating shaft 6, thereby ensuring that the two horizontal wiping plates 7 and the two sets of wiping rods 8 at the bottom rotate in opposite directions. This ensures that the movement of the two horizontal wiping plates 7 and the two sets of wiping rods 8 has opposite and equal centrifugal forces / lateral forces, which can offset each other and prevent the device from shifting, facilitating the operator to control the direction of movement of the device during movement. The wiping rods 8 at the bottom of the first rotating shaft 6 and the third rotating shaft 12 are staggered with each other. When driven by the same wiping motor 4, the rotation state of the two is consistent, so the initial staggered state can be maintained continuously, effectively preventing collisions during rotation.

[0033] As a preferred embodiment, it also includes a protective shell 20; the edge of the upper surface of the base plate 1 is also recessed with a mounting step 13, and the width of the mounting step 13 is consistent with the thickness of the protective shell 20; the protective shell 20 is covered on the mounting step 13 of the base plate 1, and the base plate 1 and the protective shell 20 are locked by lateral locking bolts 14.

[0034] In this embodiment, a protective housing 20 is provided on the base plate 1 to protect the components on the base plate 1. The protective housing 20 and the base plate 1 can be quickly positioned by the mounting step 13 on the edge of the base plate 1. The locking bolts 14 allow for quick locking and subsequent removal for maintenance.

[0035] As a preferred embodiment, an inclined anti-collision frame 15 is further provided on the edge of the lower surface of the base plate 1 .

[0036] In this embodiment, a crash barrier 15 is provided on the lower edge of the base plate 1 to provide protection for the base plate 1. The term "inclined" here refers to a vertical inclination toward the lower side of the base plate 1. It should be noted that the vertical height of the crash barrier 15 should be less than the radius of the vertically movable wheels 3 to avoid contact with the concrete surface and scratches.

[0037] As a preferred embodiment, it also includes a push cylinder 16 fixed to the lower surface of the end of the base plate 1 away from the vertical moving wheel 3, and the bottom of the piston rod of the push cylinder 16 is connected to a horizontal conical plate 17, and the tip of the conical plate 17 is facing the side of the vertical moving wheel 3.

[0038] In this embodiment, if Figure 4 As shown, a structure for scraping excess surface moisture is also provided. Specifically, the pointed end of the conical plate 17 faces the forward direction. After the concrete surface is smoothed by the trowel 8, the conical plate 17 is used to scrape the surface moisture, achieving a better finishing effect. The height of the conical plate 17 is adjusted by the push cylinder 16, which can be effectively adapted to the actual conditions of the construction site, thereby increasing the versatility of the device of the utility model.

[0039] As a further embodiment, it further includes U-shaped slide rails 18 vertically arranged on both sides of the lower surface of the base plate 1, and the conical plate 17 is provided with a limit block 19 embedded in the U-shaped slide rails 18 and sliding.

[0040] In this embodiment, U-shaped slide rails 18 are provided on both sides of the lower surface of the base plate 1 to fix the vertical position of the conical plate 17, thereby preventing the conical plate 17 from tilting due to debris on the concrete surface, thereby affecting the surface water scraping effect.

[0041] As a preferred embodiment, a plurality of the moving motors 2 and the vertical moving wheels 3 are provided, and the plurality of moving motors 2 are parallel to each other.

[0042] In this embodiment, a plurality of mutually parallel moving motors 2 are provided to drive a plurality of mutually parallel vertical moving wheels 3, thereby effectively ensuring the stability of the base plate 1 during the entire moving process.

[0043] The words "connection" and "fixation" appearing in the description of the present invention may refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meanings of the above terms in the present invention shall be understood according to the specific circumstances.

[0044] In the description of the present invention, the terms "center", "upper", "lower", "horizontal", "inner", "outer", etc., which indicate the orientation or position relationship, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation.
