Description

Technical Field

[0001] This utility model belongs to the technical field of wall plastering equipment, specifically relating to an automatic leveling and compaction device for gypsum plastering construction. Background Technology

[0002] Plaster plastering, a crucial step in wall decoration and leveling, directly determines the flatness, verticality, and appearance of the wall surface, serving as the foundation for subsequent painting, wallpapering, and other decorative work. Traditional plaster plastering relies on workers manually spreading, initially leveling, finely leveling, and compacting the plaster mortar using simple tools like trowels and scrapers. This long-standing manual method has many inherent flaws and can no longer meet the modern construction industry's demands for high efficiency, high quality, and high consistency.

[0003] Currently, the main technical problems with artificial gypsum plastering construction are as follows: 1. The construction quality is too dependent on the worker, resulting in poor consistency. The final flatness and smoothness of the wall surface depend heavily on the individual skills and experience of the plasterer. Fluctuations in the condition of different workers, or even the same worker, during construction can lead to inconsistent wall quality, making it difficult to achieve stable and uniform high-standard construction results. 2. The labor intensity is high, and the construction efficiency is low. The entire plastering process, especially when repeatedly scraping and pressing large areas of the wall with arms raised, is high-intensity physical labor, which can easily lead to rapid fatigue of the workers. This not only limits the daily construction area and reduces overall work efficiency, but also further exacerbates quality risks due to fatigue. Utility Model Content

[0004] This utility model provides an automatic leveling and compaction device for gypsum plastering construction, realizing the mechanized integration and rapid switching of leveling and compaction processes. It creatively sets up leveling and compaction mechanisms on both sides of the same rotatable mounting plate. Construction workers can switch between the two working modes of "scraping" and "compacting" within a few seconds by simply rotating the mounting plate. It realizes multi-functionality of a single machine, greatly improves the efficiency of process connection and equipment utilization, and eliminates the need to change tools.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An automatic leveling and compaction device for gypsum plastering includes a support rod with a hand-held portion on its side. Parallel upper and lower rods are located at both ends of the support rod, and a mounting plate is rotatably mounted between the upper and lower rods.

[0015] 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 scope of protection of the present utility model.

[0016] like Figures 1-3 As shown, an automatic leveling and compaction device for gypsum plastering construction includes a support rod 1, a handheld part 2 on the side of the support rod 1, and an upper rod 3 and a lower rod 4 arranged in parallel at both ends of the support rod 1. A mounting plate 5 is rotatably arranged between the upper rod 3 and the lower rod 4. A leveling mechanism is provided on one side of the mounting plate 5, and a compaction mechanism is provided on the other side of the mounting plate 5. The leveling mechanism includes a scraping motor 6 and a scraping disc 7. The rear end of the scraping motor 6 is fixed to the mounting plate 5, and the scraping disc 7 is fixed to the main shaft of the scraping motor 6. The compaction mechanism includes a compaction disc 8, which is connected to the mounting plate 5 by several limiting springs 9. A vibration motor 10 is provided on the inner side of the compaction disc 8. The control switch is located at the handheld part 2. It is powered by an external power source, or a battery can be installed at the handheld part 2 to achieve internal power supply according to usage requirements.

[0017] A limiting protection flange 11 is provided on the outer circumference of the mounting plate 5.

[0018] The mounting plate 5 has a limiting groove 12 on its limiting protection flange 11, and both the upper rod 3 and the lower rod 4 are provided with positioning bolts 13, which are adapted to the limiting groove 12.

[0019] The outer side of the leveling disc 7 is provided with several leveling strips 14.

[0020] The outer surface of the compaction disc 8 is provided with a wear-resistant protective layer.

[0021] The leveling motor 6 is a forward and reverse geared motor. Example

[0022] Leveling operation: The operator holds the equipment and rotates the mounting plate 5 to the position where the leveling plate 7 faces outward. At this time, the positioning bolts 13 of the upper and lower rods 4 are engaged in the corresponding limiting grooves 12 to lock the mounting plate 5. The leveling motor 6 is started and the leveling plate 7 rotates. The operator places the equipment on the wall surface where the plaster has been initially laid, moves the equipment, and the rotating leveling plate 7 can scrape away the excess plaster and achieve fine leveling of the wall surface. Compaction Operation: After leveling is completed, the operator loosens the positioning bolt 13, rotates the mounting plate 5 180 degrees so that the compaction plate 8 faces outward, and locks it again with the positioning bolt 13. The vibration motor 10 is started. Under the high-frequency vibration and the elastic pressure of the limit spring 9, the compaction plate 8 moves closely against the leveled gypsum surface, thereby compacting and smoothing the surface, completing the final construction.

[0023] This invention achieves mechanized integration and rapid switching between leveling and compaction processes. It creatively sets up leveling and compaction mechanisms on both sides of the same rotatable mounting plate 5. Construction workers can switch between the two working modes of "scraping" and "compacting" within seconds by simply rotating the mounting plate 5. This realizes multi-functionality of a single machine, greatly improves the efficiency of process connection and equipment utilization, and eliminates the need to change tools.

[0024] The screed is mechanically leveled by the screed motor 6 driving the screed disc 7 to rotate at high speed. The flatness no longer depends on the worker's feel and experience, effectively avoiding the wave-like undulations common in manual operation, and ensuring the stability and consistency of the wall surface quality. Several screed strips 14 on the outside of the screed disc 7 further enhance the scraping and material carrying capacity, making the leveling effect better.

[0025] The compaction mechanism uses the high-frequency vibration generated by the vibrating motor 10, combined with the elastic pressure provided by the limit spring 9, to enable the compaction disc 8 to fully expel the air in the gypsum mortar and make the material tightly bonded to the base layer. Compared with manual troweling, this mechanical compaction is more efficient and effective, and can effectively prevent the wall from becoming hollow and cracked later. The wear-resistant protective layer on the outside of the compaction disc 8 ensures the long service life and stable working performance of the equipment.

[0026] The equipment adopts a handheld design and is operated through the support rod 1 and the handheld part 2. Construction workers no longer need to perform high-intensity reciprocating scraping and pressing movements with the arm. Electric drive replaces manual labor, making operation more convenient. It is especially suitable for the construction of ceilings and large-area walls, which can significantly reduce worker fatigue and increase the daily construction area.

[0027] The limiting protection flange 11 on the outer circle of the mounting plate 5 and its limiting groove 12 cooperate with the positioning bolts 13 on the upper and lower rods 4 to ensure that the mounting plate 5 can be accurately locked in the two positions of "leveling" and "compacting", preventing accidental rotation during construction and ensuring the stability and safety of operation. In addition, the use of a forward and reverse geared motor as the leveling motor 6 allows the leveling plate 7 to change its rotation direction according to construction needs, adapting to different construction methods and further optimizing the leveling effect.

[0028] The components used in this utility model, such as the leveling disc 7, the compaction disc 8, the motor, and the vibration motor 10, are all existing conventional technologies, and their structural features will not be described in detail.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
