Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically to a concrete surface finishing device. Background Technology

[0002] In the field of building construction, concrete surface finishing is a key process to ensure project quality. Its purpose is to use professional equipment to treat the concrete surface during the initial setting stage to achieve a smooth and flat finish, thereby improving the durability and aesthetics of the concrete surface.

[0003] However, in actual construction, after the concrete is poured, local accumulation and uneven thickness often occur on the surface, which makes it impossible to cover evenly during subsequent finishing. This can easily lead to uneven surfaces and color differences. Especially in large-area construction scenarios, traditional finishing equipment is difficult to pre-treat the concrete surface and requires manual pre-leveling, which not only increases labor costs but also affects construction efficiency. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a concrete surface finishing device that automatically spreads concrete using a material distribution component, creating a uniform working surface for trowel finishing to improve construction efficiency and quality. This solves the problems of poor finishing effect and high manual pretreatment costs caused by localized accumulation and uneven thickness on the concrete surface after pouring.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a concrete surface finishing device, comprising a finishing machine body, two handles symmetrically fixedly installed on the outer side of the finishing machine body, a drive motor fixedly installed on the top of the finishing machine body, the output end of the drive motor penetrating through the finishing machine body, a base plate fixedly installed on the output end of the drive motor, a trowel plate fixedly installed on the bottom of the base plate through a connecting component, four mounting slots symmetrically opened on the outer side of the trowel plate, and a material spreading component for spreading the concrete around the trowel plate is provided inside the mounting slot.

[0006] As a preferred embodiment of the present invention, the fabric assembly includes a fabric rod, which is movably installed inside the mounting groove. A first spring is fixedly installed at one end of the fabric rod, and the other end of the first spring is fixedly installed to one side of the inside of the mounting groove.

[0007] As a preferred embodiment of the present invention, the fabric assembly further includes two limiting blocks, which are symmetrically fixedly installed on the outside of the fabric rod. Two limiting grooves are symmetrically opened inside the mounting groove, and the limiting blocks are movably sleeved inside the limiting grooves.

[0008] As a preferred technical solution of this utility model, the connecting component includes a plurality of first connecting bases, the first connecting bases are fixedly installed on the bottom of the chassis, and a first connecting rod is rotatably installed inside the first connecting base via a round rod, and a connecting groove is provided at the other end of the first connecting rod.

[0009] As a preferred embodiment of the present invention, the connecting assembly further includes a second connecting base, wherein a second connecting rod is rotatably mounted inside the second connecting base via a round rod, and the other end of the second connection is rotatably mounted inside the connecting groove via a connecting rod.

[0010] As a preferred embodiment of this utility model, a plurality of second springs are fixedly installed at the bottom of the chassis, and the other ends of the plurality of second springs are fixedly installed at the top of the wiping tray.

[0011] As a preferred embodiment of this utility model, four rubber scrapers are symmetrically fixedly installed on the outer side of the wiping disc. The rubber scrapers are arranged in a rectangular frame shape and are adapted to the outer contour of the cloth rod.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention utilizes a retractable placing rod and elastic connecting components on the outside of the trowel to achieve automatic leveling and finishing of concrete through the combined action of centrifugal force and springs. The limiting structure ensures operational stability, and the rectangular frame rubber scraper design effectively cleans residual concrete from the placing rod, thereby improving equipment reliability and construction efficiency.

[0014] The innovative connecting component adopts a linkage and second spring collaborative structure, which eliminates the drawbacks of rigid connection between chassis and tumbler. It allows the chassis to tilt or shift to a limited extent under the force of the handle. The change in chassis posture is buffered and decomposed by the flexible structure of the connecting component, avoiding uneven local pressure caused by rigid transmission to the tumbler.

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some alternative solutions or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0023] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 6 The present invention will be further described below.

[0024] A concrete surface finishing device includes a finishing machine body 1. Two handles 2 are symmetrically fixedly installed on the outer side of the finishing machine body 1. A drive motor 3 is fixedly installed on the top of the finishing machine body 1. The output end of the drive motor 3 passes through the finishing machine body 1. A base 4 is fixedly installed on the output end of the drive motor 3. A trowel 5 is fixedly installed on the bottom of the base 4 through a connecting component. Four mounting slots 12 are symmetrically opened on the outer side of the trowel 5. A material spreading component for spreading the concrete around the trowel 5 is provided inside the mounting slots 12.

[0025] In this implementation scheme, a finishing machine body 1 is set up as the basic carrier of the entire finishing device, integrating a handle 2 and a drive motor 3 to provide installation support for each component. The handle 2 is symmetrically installed on the outside of the finishing machine body 1 for easy gripping by the operator. The drive motor 3 is connected to an external power source to provide rotational power for the device. The output end of the drive motor 3 passes through the finishing machine body 1 and drives the chassis 4 to rotate, serving as the power source for the finishing action of the trowel 5 and the flattening action of the fabric assembly. The chassis 4 is used to transmit the power of the drive motor 3, and the bottom is connected to the trowel 5 through a connecting component. The bottom surface of the trowel 5 directly contacts the concrete surface, and the finishing operation of the concrete surface is completed by rotation. An installation groove 12 is opened on the outside for arranging the fabric assembly, which is the direct source of the finishing function. The mounting groove 12 is located on the outside of the trowel 5, providing space for the material spreading assembly to extend and retract in an orderly manner within the groove, ensuring the stable implementation of the leveling function. While ensuring the continuous transmission of the rotational power of the drive motor 3 to the trowel 5, the connecting assembly allows the chassis 4 to tilt or shift to a limited extent under the force applied by the handle 2. This change in the posture of the chassis 4 is buffered and decomposed by the flexible structure of the connecting assembly, avoiding uneven local pressure caused by the rigid transmission to the trowel 5. The material spreading assembly is set in the mounting groove 12, and with the help of the centrifugal force generated by the rotation of the trowel 5, it spreads and organizes the concrete piled up around the trowel 5, creating a uniform working surface for the trowel 5 to finish, improving the finishing effect. It is a key component for pre-treatment before finishing.

[0026] Specifically, the fabric assembly includes a fabric rod 14, which is movably installed inside the mounting groove 12. A first spring 16 is fixedly installed at one end of the fabric rod 14, and the other end of the first spring 16 is fixedly installed to one side of the inside of the mounting groove 12.

[0027] In this embodiment, the placing rod 14 is movably installed in the mounting groove 12. Under the centrifugal force generated by the rotation of the trowel 5, the centrifugal force on the placing rod 14 gradually increases and exceeds the initial tension of the first spring 16. At this time, the placing rod 14 overcomes the spring tension and is thrown out radially outward along the mounting groove 12, directly acting on the concrete piled up around the trowel 5. The placing rod 14 impacts the piled concrete, causing it to disperse and spread out, creating conditions for the subsequent finishing operation of the trowel 5. The mounting groove 12 is opened in the middle of the trowel 5, providing a space and track for the placing rod 14, and limiting the range of motion of the placing rod 14. One end of the first spring 16 is fixed to the placing rod 14, and the other end is connected to the inner wall of the mounting groove 12. When the placing rod 14 is thrown out by the centrifugal force, it is stretched. When the centrifugal force weakens, the first spring 16 contracts, providing the placing rod 14 with the reset power, causing it to automatically retract into the mounting groove 12, which facilitates the placing rod 14 to repeatedly perform the spreading action and maintain the cyclical operation of the placing assembly.

[0028] Specifically, the fabric assembly also includes two limiting blocks 15. The limiting blocks 15 are symmetrically fixedly installed on the outside of the fabric rod 14. Two limiting grooves 13 are symmetrically opened inside the mounting groove 12. The limiting blocks 15 are movably sleeved inside the limiting grooves 13.

[0029] In this embodiment, by setting a limiting block 15, which is symmetrically fixedly installed on the outside of the fabric rod 14 and cooperates with the limiting groove 13 in the mounting groove 12, the radial displacement and swing amplitude of the fabric rod 14 during the movement are limited, ensuring that the fabric rod 14 can only stably extend and retract along the direction of the limiting groove 13, and preventing the fabric rod 14 from detaching from the mounting groove 12 due to excessive centrifugal force or uneven force. The fabric rod 14 is movably installed inside the mounting groove 12 and forms a sliding cooperation with the limiting block 15 on the outside of the fabric rod 14, providing precise guidance for the extension and retraction movement of the fabric rod 14. The limiting groove 13 effectively constrains the movement path of the limiting block 15 and prevents the fabric rod 14 from deviating, shaking or falling off under the action of centrifugal force.

[0030] Specifically, the connecting assembly includes several first connecting bases 6, which are fixedly installed on the bottom of the chassis 4. A first connecting rod 7 is rotatably installed inside the first connecting base 6 via a round rod, and a connecting groove 8 is provided at the other end of the first connecting rod 7.

[0031] In this embodiment, the first connecting base 6 serves as the starting point of the connecting assembly and is fixed to the bottom of the chassis 4, providing a stable hinge fulcrum for the first connecting rod 7. Through the rotating structure of the round rod, the first connecting rod 7 is allowed to swing freely in the plane, realizing a flexible connection between the first connecting base 6 and the first connecting rod 7. One end of the first connecting rod 7 is hinged to the first connecting base 6 through the round rod, and the other end has a connecting groove 8, forming a dual-function structure of "rotatable-connectable". When the drive motor 3 drives the chassis 4 to rotate, the first connecting rod 7 transmits the rotational power to the connecting groove 8, and cooperates with the second connecting rod 10 through the connecting groove 8 to realize the transmission of power to the squeegee 5. The connecting groove 8 is opened at the end of the first connecting rod 7 to provide a connection interface for the second connecting rod 10, and the hinge is realized through the connecting rod.

[0032] Specifically, the connecting assembly also includes a second connecting base 9, and a second connecting rod 10 is rotatably mounted inside the second connecting base 9 via a round rod. The other end of the second connecting rod 10 is rotatably mounted inside the connecting groove 8 via a connecting rod.

[0033] In this embodiment, a second connecting base 9 is fixedly installed on the top of the shovel 5 and hinged to the second connecting rod 10 via a round rod, providing a stable rotation fulcrum for the second connecting rod 10. As a connecting component between the connecting assembly and the shovel 5, it guides the power transmitted by the second connecting rod 10 to the shovel 5. One end of the second connecting rod 10 is hinged to the second connecting base 9 via a round rod, and the other end is hinged to the connecting groove 8 of the first connecting rod 7 via a connecting rod, forming a power transmission chain of "chassis 4 - first connecting rod 7 - second connecting rod 10 - shovel 5". With the hinge structure at both ends, when the chassis 4 rotates, the power of the first connecting rod 7 is synchronously transmitted to the shovel 5. When the chassis 4 experiences local pressure due to the force applied by the handle 2, the second connecting rod 10 can swing around the hinge point. In conjunction with the first connecting rod 7 and the second spring 11, the pressure is converted into a flexible buffer between the connecting rods, avoiding the hard transmission to the shovel 5 and causing uneven force.

[0034] Specifically, a number of second springs 11 are fixedly installed at the bottom of the chassis 4, and the other end of the second springs 11 is fixedly installed at the top of the smear plate 5.

[0035] In this implementation scheme, a second spring 11 is installed between the chassis 4 and the wiping plate 5. Through elastic deformation, mechanical stress is buffered. When the operator presses the handle 2 locally, the second spring 11 is compressed, adjusting the distance between the chassis 4 and the wiping plate 5, so that the pressure on the wiping plate 5 is distributed, avoiding excessive local force and ensuring uniform pressure transmission during finishing.

[0036] Specifically, four rubber scrapers 17 are symmetrically fixedly installed on the outer side of the smearing plate 5. The rubber scrapers 17 are arranged in a rectangular frame shape and are adapted to the outer contour of the cloth rod 14.

[0037] In this implementation scheme, a rubber scraper 17 is symmetrically fixed to the outside of the trowel 5 in a rectangular frame shape, with its outline precisely matched to the concrete placing boom 14. When the concrete placing boom 14 retracts after completing the concrete leveling operation, the rubber scraper 17 quickly removes the residual concrete adhering to the surface of the concrete placing boom 14 through a scraping action, avoiding the residual concrete from affecting the normal storage and next use of the concrete placing boom 14, ensuring that the concrete placing assembly works continuously and efficiently, and indirectly ensuring the finishing quality and the smooth operation of the equipment.

[0038] In summary: When using this utility model, the operator manually holds the handle 2 on the outside of the finishing machine body 1, pushes the device to the area to be finished and adjusts the finishing path. After the drive motor 3 is started by the external power supply, its output end passes through the finishing machine body 1 and drives the chassis 4 to rotate, providing power to the device. The bottom of the chassis 4 is connected to the wiping tray 5 through a connecting assembly. The first connecting base 6 in the connecting assembly is fixed to the bottom of the chassis 4. The first connecting rod 7 is rotatably installed through a round rod. The connecting groove 8 at the other end of the first connecting rod 7 is hinged to the second connecting rod 10 through a connecting rod. The second connecting rod 10 is rotatably connected to the second connecting base 9 fixed to the top of the wiping tray 5 through a round rod. When the operator applies local force through the handle 2, the first connecting rod 7 and the second connecting rod 10 can swing around the hinge point. With the cooperation of the second spring 11 between the bottom of the chassis 4 and the top of the wiping tray 5, the distance can be adjusted by compressing or extending the second spring 11, dispersing the local pressure on the wiping tray 5 and avoiding uneven force. The wiping tray 5 rotates and finishes under the action of power. The mounting groove 12 on its outside provides support for the fabric assembly. Provided with working space, the placing rod 14 is movably installed in the mounting groove 12, with one end connected to the first spring 16. When the trowel 5 rotates, the placing rod 14 generates outward acceleration under the action of centrifugal force, causing the first spring 16 to gradually stretch from its natural length. The spring tension increases with the increase of deformation, but when the centrifugal force is continuously greater than the spring tension, the placing rod 14 continues to be thrown out to the opening end of the mounting groove 12. Its end spreads and flattens the concrete accumulated around the trowel 5, creating a uniform working surface for subsequent finishing. When the centrifugal force weakens, the first spring 16 pulls it back. The limiting block 15 on the outside of the placing rod 14 cooperates with the limiting groove 13 in the mounting groove 12 to ensure that the placing rod 14 can extend and retract stably along the limiting groove 13 and prevent it from falling off. When the placing rod 14 retracts, the rectangular rubber scraper 17 on the outside of the trowel 5 is adapted to the contour of the placing rod 14 and removes the residual concrete on its surface by scraping, so as to avoid affecting the storage and the next use, and ensure that the placing assembly can continue to work, thereby realizing the complete operation process of concrete from leveling to finishing.
