[0019] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1

[0021] As shown in the figure, this embodiment discloses a vibrating trowel device with variable elasticity, including a vehicle body 1, a lifting mechanism 2, a trowel mechanism 3, an elasticity adjustment mechanism 4, a rough scraper 5 and a controller;

[0022] The lifting mechanism 2 is arranged behind the moving direction of the vehicle body 1, and the output end of the lifting mechanism 2 is connected to the rough scraper 5. The lifting and lowering of the lifting mechanism 2 controls the lifting and lowering of the rough scraper 5. The lifting mechanism 2 is also provided with a first laser radar 7 for measuring the height from the ground. The smoothing mechanism 3 is arranged behind the moving direction of the rough scraper 5 through the elastic adjustment mechanism 4. When the vehicle body 1 is moving forward, the rough scraper 5 first performs a rough scraping and smoothing on the concrete floor, and the smoothing mechanism 3 then performs fine scraping and slurrying on the concrete floor. The elastic adjustment mechanism 4 can provide a rebound force when the smoothing mechanism 3 vibrates downward to perform a slurrying operation. The tightness of the elastic adjustment mechanism 4 can be adjusted to adjust the size of the rebound force on the smoothing mechanism 3. When the rough scraper 5 is driven to rise and fall by the lifting mechanism 2, the smoothing mechanism 3 is driven to rise and fall by the elastic adjustment mechanism 4;

[0023] The controller is arranged in the vehicle body 1, and the controller is connected with the first laser radar 7 and the lifting mechanism 2 by signal. After the first laser radar 7 measures the height from the ground, it transmits the data signal to the controller. The controller is preset with data of the working height when the smoothing mechanism 3 is working. The controller then compares the measured height data with the working height data, and the difference is the value of the controller controlling the lifting and lowering of the lifting mechanism 2, thereby adjusting the lifting and lowering of the smoothing mechanism 3 to reach the working height for operation.

[0024] The working principle and use process of this embodiment:

[0025] When the present invention is in use, after the first laser radar 7 measures the height data from the ground, it is compared with the height data preset in the controller. The difference is the height at which the smoothing mechanism 3 needs to be raised and lowered. The controller connects the lifting mechanism 2 through a signal to control the lifting and lowering of the lifting mechanism 2. The lifting and lowering of the lifting mechanism 2 drives the rough scraper 5 to rise and fall. The smoothing mechanism 3 is connected to the rough scraper 5 through the elastic adjustment mechanism 4. The lifting and lowering of the rough scraper 5 drives the smoothing mechanism 3 to rise and fall so that the smoothing mechanism 3 reaches the working height and contacts the concrete floor. At this time, the controller controls the vehicle body 1 to travel. During the forward driving of the vehicle body 1, the smoothing mechanism 3 can be driven to smooth the cement surface and perform slurry raising operations. The elastic adjustment mechanism 4 is connected to the smoothing mechanism 3. During the slurry raising operation, when the smoothing mechanism 3 faces different concrete floors, the resilience of the elastic adjustment mechanism 4 can be changed according to the slurry raising requirements of different concrete floors, so that the smoothing mechanism 3 can provide different vibration effects for different concrete floor conditions to improve the slurry raising quality.

[0026] Embodiment 2

[0027] As shown in the figure, this embodiment is developed on the basis of the above-mentioned embodiment. Specifically, this embodiment defines the specific structure of the elastic adjustment mechanism 4. There are two elastic adjustment mechanisms 4, which are symmetrically arranged on the smoothing mechanism 3 along the midline of the long side of the smoothing mechanism 3. The smoothing mechanism 3 is connected to the rough scraper 5 through two elastic adjustment mechanisms 4, which can ensure the connection stability of the smoothing mechanism 3. If there is only one elastic adjustment mechanism 4, the smoothing mechanism 3 may shake during operation.

[0028] Furthermore, the elastic adjustment mechanism 4 includes a fixed seat 41, a first guide rod 42, a first linear bearing seat 43, a spring 44, an adjustment sleeve 45 and a fixing member 46, one end of the fixing member 46 is arranged on the rough scraper 5, and the other end is sleeved on the first linear bearing seat 43. In order to ensure the installation stability, the number of fixing members 46 can be set to two, which are sleeved on the upper and lower ends of the first linear bearing seat 43. The first linear bearing seat 43 is sleeved on the first guide rod 42. The upper end of the first guide rod 42 is provided with the adjustment sleeve 45, and the lower end is provided on the fixed seat 41. The fixed seat 41 is provided on the smoothing mechanism 3, and the exposed part of the first guide rod 42 is wound with the spring 4 4. When the smoothing mechanism 3 is performing the slurry lifting operation, the smoothing mechanism 3 will move downward, which will drive the fixing seat 41 to move downward, thereby driving the first guide rod 42 to move downward. Since the first linear bearing seat 43 is fixed by the fixing member 46 and cannot move, the spring 44 wound on the first guide rod 42 will be stretched, thereby generating a rebound force to pull the smoothing mechanism 3 back. In the process of the up and down movement of the smoothing mechanism 3, the slurry lifting operation on the concrete floor is completed. When it is necessary to adjust the elastic force of the elastic adjustment mechanism 4, springs 44 with different elastic coefficients and lengths can be selected, and the preload force of the spring 44 can be adjusted by adjusting the installation position of the sleeve 45, thereby adjusting the elastic force of the elastic adjustment mechanism 4 to change the rebound force on the smoothing mechanism 3.

[0029] Embodiment 3

[0030] As shown in the figure, this embodiment is developed on the basis of the above-mentioned embodiment. Specifically, this embodiment limits the specific structure of the lifting and adjusting mechanism. There are two lifting mechanisms 2, which are symmetrically arranged on the left and right sides behind the moving direction of the vehicle body 1. The coarse scraper 5 is connected by two lifting mechanisms 2, which can ensure that the installation of the coarse scraper 5 is more stable and does not shake.

[0031] Furthermore, the lifting mechanism 2 includes a mounting plate 21, a second guide rod 22, a second linear bearing seat 23, an electric cylinder 24 and a connecting piece 25, one end of the mounting plate 21 is arranged on the vehicle body 1, and the other end is sleeved on the second linear bearing seat 23, the second linear bearing seat 23 is sleeved on the second guide rod 22, the first laser radar 7 is arranged on the upper end of the second guide rod 22, the lower end of the second guide rod 22 is connected to the rough scraper 5, the electric cylinder 24 is arranged on the mounting plate 21, and the output end of the electric cylinder 24 can be lifted up and down and connected to the second guide rod 22 through the connecting piece 25. The second guide rod 22 and the electric cylinder 24 are connected to the controller signal, and the controller transmits a control signal to the electric cylinder 24, thereby controlling the operation of the electric cylinder 24. The output end of the electric cylinder 24 can move up and down. When it is necessary to control the smoothing mechanism 3 to rise, the output end of the electric cylinder 24 is extended, and the second guide rod 22 is controlled to rise through the connecting piece 25, thereby driving the rough scraper 5 to rise, and finally driving the smoothing mechanism 3 to rise. When it is necessary to control the smoothing mechanism 3 to descend, the output end of the electric cylinder 24 retracts, and the second guide rod 22 is controlled to descend through the connecting piece 25, thereby driving the rough scraper 5 to descend, and finally driving the smoothing mechanism 3 to descend.

[0032] Embodiment 4

[0033] As shown in the figure, this embodiment is developed on the basis of the above-mentioned embodiment. Specifically, this embodiment defines the specific structure of the smoothing mechanism 3, and the smoothing mechanism 3 includes a smoothing plate 31 and a vibration motor 32. The vibration motor 32 is arranged at the center above the smoothing plate 31. The vibration of the vibration motor 32 provides downward pressure, so that the smoothing plate 31 contacts the concrete floor, thereby completing the slurry raising and leveling operation.

[0034] Embodiment 5

[0035] As shown in the figure, this embodiment is developed on the basis of the above-mentioned embodiment. Specifically, this embodiment limits the specific structure of the smoothing mechanism 3. The vehicle body 1 is also provided with a second laser radar 6 for detecting the terrain around the vehicle body 1. The second laser radar 6 is connected to the controller signal. After the second laser radar 6 detects the surrounding terrain data, it transmits the data to the controller. The controller then automatically controls the driving and obstacle avoidance of the vehicle body 1 according to the terrain data.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
