Troweling equipment primarily consists of a motor, a rotating shaft, and a connecting rod. The shaft is connected to the motor, and the connecting rod is integrally formed with the shaft. A trowel plate is welded to the connecting rod.

[0004] After long-term use, the trowel plate is worn out, and the trowel plate welded on the connecting rod causes great obstacles for the staff to replace the trowel plate, resulting in low convenience of use of the trowel equipment, so it needs to be improved. Utility Model Content

[0024] The following is combined with Figure 1-3 This application is described in further detail.

[0025] The embodiment of the present application discloses an automatic floor troweling device. Figure 1 and Figure 2 An automatic floor troweling device includes a tracked vehicle 1, an adjustment assembly 2, a support tube 3, and a troweling assembly 4. One side of the adjustment assembly 2 is connected to the tracked vehicle 1 and the other side is connected to the support tube 3. The adjustment assembly 2 is used to adjust the position of the support tube 3. The troweling assembly 4 includes a troweling frame 41, a driving member 42, and a troweling member 43. A connecting ring 411 is fixed to the troweling frame 41, and the outer wall of the connecting ring 411 is threadedly connected to the inner wall of the support tube 3. The driving member 42 is arranged on the inner side of the connecting ring 411. The troweling member 43 is arranged on the side of the troweling frame 41 away from the support tube 3 and is connected to the driving member 42. The driving member 42 is used to drive the troweling member 43. When the floor needs to be troweled, the worker selects the troweling member 43 of the corresponding model, then aligns the connecting ring 411 with the support tube 3 so that the outer wall of the connecting ring 411 is threadedly connected to the inner wall of the support tube 3, and the installation of the troweling frame 41 is completed. At this time, the connection ring 411 enables the rapid installation and removal of the trowel frame 41 and the trowel member 43, thereby improving the convenience of using the trowel device. At the same time, the adjustment assembly 2 facilitates troweling of different locations on the ground, thereby expanding the applicability of the trowel device.

[0026] Reference Figure 1 and Figure 2The adjustment assembly 2 includes a first connecting plate 21 and a second connecting plate 22. The first connecting plate 21 is slidably connected to the tracked vehicle 1 in the vertical direction. The second connecting plate 22 is rotatably connected to the end of the first connecting plate 21 away from the tracked vehicle 1. The second connecting plate 22 is connected to the support cylinder 3 through the lifting assembly 5.

[0027] A bracket 11 is fixed to the crawler vehicle 1. A screw rod 111 is rotatably connected to the bracket 11. A first motor 112 is fixed to the bracket 11. The screw rod 111 is coaxially fixed to the output end of the first motor 112. A guide rod 113 is fixed to the bracket 11. A first connecting plate 21 is slidably connected to the guide rod 113. A second motor 211 is fixed to the first connecting plate 21. The output end of the second motor 211 is fixed to the second connecting plate 22.

[0028] When the trowel assembly 4 is in use, the first motor 112 rotates the screw 111. Under the guidance and limiting action of the guide rod 113, the screw 111 drives the first connecting plate 21 to move vertically. The second motor 211 then rotates the second connecting plate 22, which in turn rotates the support cylinder 3 and the trowel assembly 4, thereby expanding the applicability of the trowel device.

[0029] Reference Figure 1 The lifting assembly 5 includes an electric push rod 51, a lifting cylinder 52, and a lifting rod 53. The electric push rod 51 is fixed to the second connecting plate 22, and the lifting cylinder 52 is fixed vertically to the support cylinder 3. One end of the lifting rod 53 is connected to the second connecting plate 22, and the other end is slidably connected to the inner wall of the lifting cylinder 52. A corrugated ring 6 is fixed between the second connecting plate 22 and the support cylinder 3, and the corrugated ring 6 is provided outside the lifting cylinder 52 and the lifting rod 53.

[0030] After the position of the second connecting plate 22 is adjusted, the electric push rod 51 drives the support cylinder 3 to move, and the support cylinder 3 in turn drives the trowel frame 41 to move, so that the trowel member 43 can more stably trowel the floor. At the same time, under the action of the corrugated ring 6, foreign matter is less likely to affect the lifting cylinder 52 and lifting rod 53, so that the support cylinder 3 can move more stably.

[0031] Reference Figure 1 and Figure 3 The trowel member 43 includes a main shaft 431 and a plurality of connecting rods 432. The main shaft 431 is rotatably connected to the trowel frame 41. Each connecting rod 432 is evenly fixed on the main shaft 431 along the circumferential direction of the main shaft 431, and each connecting rod 432 is detachably connected to a trowel plate 433.

[0032] A fixing ring 434 is fixed to the trowel plate 433. Each fixing ring 434 is sleeved on the corresponding connecting rod 432. A fixing post 435 is rotatably connected to the fixing ring 434. The fixing post 435 extends into the corresponding connecting rod 432 and is threadedly connected to the connecting rod 432. The fixing post 435 is configured as a bolt.

[0033] When the trowel plate 433 is needed, the worker puts the fixing ring 434 on the connecting rod 432 at the corresponding position, and then inserts the fixing column 435 into the fixing ring 434, so that the fixing column 435 is threadedly connected to the connecting rod 432 to realize the installation of the trowel plate 433, thereby providing convenience for the installation and disassembly of the trowel plate 433.

[0034] Reference Figure 1 The driving member 42 includes a third motor 421, a first bevel gear 422, and a second bevel gear 423. The third motor 421 is fixed to the trowel frame 41. The first bevel gear 422 is coaxially fixed to the output end of the third motor 421. The second bevel gear 423 is coaxially fixed to the main shaft 431 and meshes with the first bevel gear 422. The third motor 421 is driven by a battery.

[0035] The electric push rod 51 controls the movement of the trowel frame 41 so that the trowel plate 433 contacts the ground. The third motor 421 then drives the first bevel gear 422 to rotate. The first bevel gear 422 in turn drives the second bevel gear 423 and the main shaft 431 to rotate, which can drive each connecting rod 432 to rotate, so that each trowel plate 433 rotates, thereby realizing the function of automatically troweling the ground.

[0036] Reference Figure 1 A protective shell 7 is fixed to the trowel frame 41. The protective shell 7 covers the outside of each connecting rod 432 and the trowel plate 433. A plurality of ball bearings 71 are embedded on the side of the protective shell 7 away from the trowel frame 41. The ball bearings 71 are evenly distributed along the circumference of the protective shell 7. The protective shell 7 makes the trowel assembly 4 less susceptible to external environmental influences during operation and reduces the possibility of injury to construction workers caused by the trowel plate 433. The ball bearings 71 also convert the sliding friction between the protective shell 7 and the ground into rolling friction, reducing the friction between the protective shell 7 and the ground, thereby reducing the possibility of damage to the protective shell 7 and facilitating the more stable operation of the trowel assembly 4.

[0037] The implementation principle of an automatic floor troweling device in an embodiment of the present application is as follows: when the troweling assembly 4 needs to be used, the worker aligns the connecting ring 411 with the supporting tube 3 so that the outer wall of the connecting ring 411 is threadedly connected to the inner wall of the supporting tube 3, thereby completing the installation between the supporting tube 3 and the troweling frame 41, providing convenience for the installation and disassembly of the troweling frame 41, thereby improving the convenience of using the troweling equipment.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
