Technical Field

[0001] This utility model relates to the field of floor troweling machine technology, specifically a floor troweling machine for building construction. Background Technology

[0002] A floor trowel, also known as a cement finishing machine, has a main structure consisting of a trowel rotor driven by an electric motor or gasoline engine. Two to four trowels are mounted on the bottom of the cross-shaped part in the middle of the rotor.

[0003] A search revealed prior art publication number CN222375139U, which discloses an adjustable floor trowel, including a frame, a protective ring, a handrail tube, and casters. A support frame is mounted at the lower end of the frame, and the protective ring is mounted to the lower end of the frame via the support frame. The handrail tube is mounted on one side of the support frame, and the casters are mounted around the outer wall of the protective ring. A support frame is provided around the protective ring, and a support column is rotatably mounted inside the support frame. A forward and reverse motor is located on one side of the support frame, and the output shaft of the forward and reverse motor is connected to the support column. This utility model relates to the field of construction equipment technology, specifically an adjustable floor trowel. This device facilitates transportation and movement, and allows for adjustment of the angle and length of use, improving ease of use.

[0004] Currently, the floor trowels commonly used in construction projects have a fixed preset troweling force when processing cement floors. This requires workers to rely on their personal experience to manually adjust uneven areas during the troweling process, which greatly reduces the ease of operation of the trowel. Therefore, based on the above research and in combination with existing problems, a floor trowel for construction projects is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a floor smoothing machine for construction projects to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Please refer to Figures 1-5A floor smoothing machine for construction engineering includes a mounting box 1 and a drive mechanism 2. A handle 101 is fixedly mounted on the side of the mounting box 1, and a protective cover 102 is provided at the lower end of the mounting box 1. The drive mechanism 2 includes a drive motor 201, a transmission box 202, and a smoothing plate 205. The drive motor 201 is fixedly mounted on the upper end of the mounting box 1, and the transmission box 202 is fixedly mounted on the side of the mounting box 1. The transmission box 202 is a transmission component as used in the prior art, consisting of a drive shaft, a transmission assembly, and a rotating shaft. The output end of the drive motor 201 is fixedly connected to the drive shaft of the transmission box 202. A connecting cylinder 203 is fixedly mounted at the lower end of the mounting box 1. The lower end of the connecting cylinder 203 is rotatably connected to a rotating ring 204. The connecting cylinder 203 is filled with nitrogen gas at two atmospheres, and the lower end of the connecting cylinder 203 is rotatably connected to the rotating ring 204 in a sealed manner. The rotating ring 204 is provided with an adjustment mechanism 3 for adjusting the smoothing force of the trowel 205. Specifically, when the trowel is in normal use, the contact area between the trowel 205 and the ground is the entire side of the trowel 205. When the angle of the trowel 205 is adjusted by the adjustment mechanism 3, the contact area between the trowel 205 and the ground begins to decrease, thus changing the smoothing force. This makes it more convenient for workers to adjust the smoothing force by adjusting the mechanism 3.

[0027] Please see Figures 1-5 A mounting ring 209 is fixedly installed at the lower end of the rotating ring 204. The mounting ring 209 has multiple mounting slots arranged in an array, and a mounting block 210 is fixedly installed in each mounting slot. A sliding block 211 is slidably installed on the inner wall of each mounting block 210. A trowel plate 205 is rotatably mounted on one end of the sliding block 211. A torsion spring (not shown in the diagram) is provided between the trowel plate 205 and the sliding block 211 to ensure that the trowel plate 205 is parallel to the ground in its normal state. The mounting block 210 and the sliding block 211... A pneumatic telescopic rod 213 is fixedly installed between 1, and multiple pneumatic telescopic rods 213 are provided. Each input end of the pneumatic telescopic rod 213 is fixedly installed with a vent block 212. The vent block 212 is located inside the connecting cylinder 203. When the ground is uneven, the squeegee 205 tilts upward, causing the sliding block 211 to start moving upward. The pneumatic telescopic rod 213 plays a shock-absorbing role for the sliding block 211, preventing the squeegee 205 from being damaged due to up-and-down bumping when squeegeeing on uneven ground.

[0028] Please see Figures 1-4A transmission cylinder 208 is rotatably mounted on the inner wall of the connecting cylinder 203, and a rotating ring 204 is fixedly mounted on the lower end of the transmission cylinder 208. A driven gear 207 is fixedly mounted on the upper end of the transmission cylinder 208. A drive gear 206 is fixedly mounted on the rotating shaft of the transmission box 202, and the drive gear 206 and the driven gear 207 are meshed together. When the drive motor 201 starts to work, it drives the drive gear 206 to rotate through the transmission box 202, causing the driven gear 207 to rotate. The driven gear 207 drives the rotating ring 204 to rotate through the transmission cylinder 208, so that the trowel 205 smooths the ground.

[0029] Please see Figures 1-4 The adjustment mechanism 3 includes an adjustment handle 301, which is fixedly installed at the end of the handle 101 away from the mounting box 1. A control handle 302 is fixedly installed at the end of the handle 101 close to the adjustment handle 301. A control line 304 is fixedly installed at the output end of the control handle 302, and the other end of the control line 304 is fixedly installed at the control end of the drive motor 201. When it is necessary to control the smoothing speed, the control handle 302 is controlled to control the output power of the drive motor 201 through the control line 304, thereby adjusting the rotation speed of the smoothing plate 205, making it more convenient for workers to control the smoothing rotation speed through the control handle 302.

[0030] Please see Figures 1-4 An adjustment line 303 is fixedly installed at the output end of the adjustment handle 301. An electric telescopic rod 309 is fixedly installed at the end of the adjustment line 303 away from the adjustment handle 301. A gear 306 is fixedly installed at the output end of the electric telescopic rod 309. A sliding groove 305 is slidably sleeved on the side end of the gear 306, and the sliding groove 305 is fixedly installed on the inner wall of the mounting box 1 to prevent the gear 306 from shifting during movement. The gear 306 meshes with the adjustment gear 307, and the adjustment gear 307 is rotatably installed on the inner wall of the mounting box 1. An adjustment rod 308 is fixedly installed at the lower end of the adjustment gear 307. Multiple adjustment bolts 310 are arrayed at the lower end of the adjustment rod 308, and the adjustment bolts 310 are rotatably installed at the lower end of the adjustment rod 308.

[0031] Please see Figures 1-5A connecting rod 312 is rotatably mounted on the inner wall of the sliding block 211, and the connecting rod 312 is fixedly mounted on the side end of the trowel 205. An adjusting plate 311 is fixedly mounted on the end of the connecting rod 312 away from the trowel 205, and an adjusting bolt 310 abuts against the upper end of the adjusting plate 311. When it is necessary to adjust the trowel rotation and smoothing force, the adjusting handle 301 is controlled. The adjusting handle 301 causes the electric telescopic rod 309 to start working and extending through the adjusting line 303. The electric telescopic rod 309 pushes the gear 306 to start moving, and the adjusting gear 307 starts to rotate, causing the adjusting rod 308 to drive the adjusting bolt 310 to start rotating. The adjusting bolt 310 squeezes and pushes the adjusting plate 311, causing the connecting rod 312 to drive the sliding groove 305 to start rotating, thus making it more convenient to adjust the smoothing force of the trowel 205.

[0032] Working principle: When the operator needs to use the power trowel, the output power of the drive motor 201 is controlled by the control handle 302, thereby adjusting the rotation speed of the trowel plate 205. Once the rotation speed of the trowel plate 205 is adjusted to a suitable speed, the adjustment handle 301 is controlled, and the electric telescopic rod 309 is extended through the adjustment line 303. The electric telescopic rod 309 pushes the rack 306 to move, and the adjustment gear 307 starts to rotate, causing the adjustment rod 308 to drive the adjustment bolt 310 to rotate. The adjustment bolt 310 presses and pushes the adjustment plate 311, causing the connecting rod 312 to drive the sliding groove 305 to rotate, making the use of the power trowel more convenient.

[0033] When the trowel moves to an uneven surface, as the trowel plate 205 is pushed upward by the protruding ground, the sliding groove 305 drives the adjusting plate 311 to rise through the connecting rod 312, causing the adjusting bolt 310 to press the adjusting plate 311 to start rotating, so that the contact force between the trowel plate 205 and the ground is kept within a suitable range, thereby making the trowel more stable when smoothing uneven ground.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
