Abstract
Description
Technical Field
[0001] This utility model relates to the field of floor leveling machine technology, specifically an automatic floor leveling machine for building engineering. Background Technology
[0002] A floor screed is a type of construction machinery used to level ground. It is mainly used for the construction and leveling of concrete floors. Handheld vibratory screeds are primarily used in small-area construction. The main principle is to use vibration to compact loose concrete and sand layers, thereby achieving the purpose of leveling the ground. During operation, the equipment can generate high-frequency vibration energy, which effectively reduces the density of loose material layers and improves the flatness and compaction of the ground.
[0003] An investigation revealed that a Chinese utility model patent (publication number: CN220184556U) discloses a floor leveling device, including a mounting base; the mounting base has a flat plate fixedly connected to its lower end, a connecting frame is provided on the rear side of the mounting base, a connecting rod is provided on the upper end of the connecting frame, and handles are symmetrically connected to the upper side of the outer arc surface of the connecting rod by connecting bolts; a vibration motor is provided inside the mounting base; it also includes a mounting plate, which is located between the upper sides of the two handles, and a battery and a control switch are respectively provided at the front end of the mounting plate. The input end of the control switch is electrically connected to the output end of the battery, and the input end of the vibration motor is electrically connected to the output end of the control switch. It also includes extension plates, which are respectively hinged to the left and right ends of the flat plate. This floor leveling device can change the overall length of the flat plate according to the specific conditions of the floor, and is suitable for different floor leveling tasks, with a wide range of applications.
[0004] Although the aforementioned patent allows for flexible adjustment of the overall length of the flat plate through the setting of the extension plate, the horizontal distribution of the flat plate still needs to be controlled by the hand handle during use. However, since the hand handle is prone to angular deviation, the flat plate may tilt during displacement, which in turn causes the flat plate to have pressure indentations on the floor surface, thus affecting its leveling effect.
[0005] Therefore, this utility model provides an automatic floor leveling machine for building construction to solve the above problems. Utility Model Content

[0024] 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.
[0025] like Figure 1-4As shown, this utility model provides an automatic floor leveling machine for construction engineering, including a leveling scraper 1, a leveling component 2 connected above the leveling scraper 1; a handheld component 3, which includes a positioning rod 31, one end of which is fixedly connected to the leveling component 2, and the other end of which is rotatably connected to a handle 33 via a rotating pin 34, and a positioning plate 36 is fixedly connected to the outer wall of the positioning rod 31; and a support component 4, which provides auxiliary support for the handheld component 3, and includes two first hinge seats 41. The receiving seat 41 is fixedly connected to the outer wall of the positioning plate 36. An adjusting rod 42 is hinged to the outer wall of the first hinge seat 41. A positioning frame 43 is sleeved on the outside of the adjusting rod 42. A wheel 44 is rotatably connected to the other end of the positioning frame 43. By setting the support component 4, the handheld component 3 can be assisted in supporting it, thereby improving the stability of the handheld component 3 and avoiding large angle deviations during the handheld process. This improves the horizontal contact between the leveling scraper 1 and the floor surface during the use of the device, thereby improving the leveling efficiency of the floor surface.
[0026] Furthermore, the leveling component 2 includes a support base 21, which is fixedly welded to the upper surface of the horizontal end of the leveling scraper 1. A vibration motor 23 is connected to the upper part of the support base 21 via a first rubber spring 22. Connecting plates 25 are connected to the inner walls of both ends of the support base 21 via second rubber springs 24. A positioning rod 31 is fixedly connected to the outer wall of the connecting plate 25 via bolts. The two ends of the support base 21 are bent upwards at a 90-degree angle. Four sets of first rubber springs 22 and second rubber springs 24 are provided, and two sets of second rubber springs 24 are connected to the outside of each connecting plate 25. With this structure, high-frequency vibration can be achieved when the vibration motor 23 is started, thereby driving the leveling scraper 1 to vibrate at high frequency. Through its high-frequency vibration, the density of the loose material layer is effectively reduced, and the flatness and compaction of the ground are improved.
[0027] Furthermore, an adjusting ring 32 is integrally provided at the end of the positioning rod 31 near the handle 33, and a threaded rod 35 is rotatably provided inside the adjusting ring 32. The threaded rod 35 extends to the outside of the handle 33, and a nut is threadedly connected to the outer wall of the threaded rod 35. The adjusting ring 32 has an arc-shaped structure, and a convex-shaped limiting groove is opened inside the adjusting ring 32. The end of the threaded rod 35 located inside the limiting groove has a stepped structure, and the side of the adjusting ring 32 near the handle 33 has a wavy structure. Through the connection between the threaded rod 35 and the nut, the angle of the handle 33 can be flexibly adjusted, thereby allowing the handheld end of the handle 33 to be height-adjusted to meet the comfortable handheld operation of operators of different heights. At the same time, the wavy structure on the surface of the adjusting ring 32 can play a locking and positioning role on the outer wall of the handle 33, thereby improving the stability of the handle 33 under the compression state after the angle is adjusted, and preventing the handle 33 from shifting during the operation of the device.
[0028] Furthermore, the end of the positioning frame 43 is provided with a positioning hole, and the adjusting rod 42 is provided with adjusting holes evenly distributed. Bolt fasteners pass through the positioning holes and the corresponding adjusting holes. The outer wall of the adjusting rod 42 is integrally provided with a second hinge seat 46, and a cylinder 45 is hinged between the second hinge seat 46 and another first hinge seat 41. Through the setting of the cylinder 45, the support angle of the adjusting rod 42 can be further assisted to pull, thereby improving the stability of the adjusting rod 42 and the positioning frame 43 after the angle is adjusted, and thus providing a good support effect for the handheld component 3.
[0029] Working principle: First, the height of the handheld end of the handle 33 is adjusted according to the operator's height to ensure the comfort of hand operation of the device. Then, the support component 4 is adjusted so that the wheel 44 contacts the ground. When the device is pulled by the handheld handle 33, the leveling scraper 1 contacts the ground surface and can horizontally level the ground surface. At the same time, the high-frequency vibration of the leveling component 2 can drive the leveling scraper 1 to vibrate synchronously, effectively reducing the density of the loose material layer and improving the flatness and compaction of the ground.
[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
