Technical Field

[0001] The utility model relates to the technical field of trowel machines, in particular to a counterweight mechanism for trowel machines. Background Art

[0002] A trowel is a mechanical device used to polish, grind or grind the surface of a workpiece. The trowel is usually driven by an electric motor, and through rotation or vibration, the trowel material (such as trowel cloth, trowel pad, etc.) on the trowel disc contacts the surface of the workpiece, thereby processing the surface of the workpiece.

[0003] When performing cold-mix permeable asphalt curved garden road leveling operations, in order to ensure the aesthetic effect of the finished surface, the conventional process on the market is to directly use a polishing machine to compact and finish the surface. However, during the actual implementation process, it was found that directly using a polishing machine to finish the surface is difficult to meet the compaction requirements, and the common problem of cold-mix colored asphalt, the appearance of loose particles, will occur.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0032] like Figure 1 —3, the specific scheme of the embodiment is as follows: it includes a driving device 1, a protective cover 101 is installed on the outer side of the driving device 1, the protective cover 101 is used to protect the operator from splashes, debris or other dangerous substances that may be generated when the trowel machine is running, and a handrail 102 is fixedly installed outside the driving device 1. A smoothing tool holder 2 is installed at the output end of the driving device 1. The number of the smoothing tool holders 2 is five, and the angle from the center point of each smoothing tool holder 2 to the center point of another smoothing tool holder 2 is 72 degrees. The smoothing tool holder 2 can increase the stability and balance of the trowel disc 3, reduce vibration and swing during the troweling process, and improve the stability and accuracy of the processing. The end of the smoothing tool holder 2 away from the driving device 1 is fixedly connected to the trowel disc 3, and the surface of the trowel disc 3 is installed with a counterweight assembly 4.

[0033] The counterweight assembly 4 includes an installation box 41 fixedly installed on the surface of the wiping plate 3. The number of the installation boxes 41 is five, and the installation boxes 41 are located between the angles of the smoothing tool holder 2. The installation boxes 41 are distributed between the smoothing tool holders 2, so that the wiping plate 3 can maintain balance and vibration characteristics. The surface of the installation box 41 is provided with a perforation and a threaded hole, and the threaded hole is located at the center of the installation box 41. The bottom wall of the inner side of the installation box 41 is fixedly connected with a positioning column 411, and the number of the positioning columns 411 is nine. The outer side of the installation box 41 is fixedly connected with a connecting plate 412, and the connecting plate 412 is fixedly connected to the wiping plate 3 by fixing bolts. The setting of the fixing bolts and the connecting plate 412 allows the installation box 41 to be easily disassembled and assembled;

[0034] A counterweight seat 42 is installed on the inner side of the installation box 41. The specifications of the counterweight seat 42 are compatible with the specifications of the inner wall of the installation box 41. A positioning groove 421 matching the positioning column 411 is opened at the lower end of the counterweight seat 42. When one end of the counterweight seat 42 contacts the bottom wall of the installation box 41, the positions of the positioning groove 421 and the positioning column 411 are on the same vertical line. The cooperation between the positioning groove 421 and the positioning column 411 can prevent the counterweight seat 42 from shaking left and right on the inner side of the installation box 41.

[0035] The end of the installation box 41 away from the wiper plate 3 is threadedly connected with a fastening screw 43 that penetrates and extends to the inside of the installation box 41. The fastening screw 43 is threadedly connected to the threaded hole. The upper end of the fastening screw 43 is fixedly connected with a rotating seat 431. The rotating seat 431 is located between the gaps of the protective cover 101. The end of the fastening screw 43 located inside the installation box 41 is movably connected with a pressing plate 44. The specifications of the pressing plate 44 are adapted to those of the counterweight seat 42. By rotating the fastening screw 43, the pressing plate 44 moves downward to squeeze the counterweight seat 42. With the cooperation of the threaded hole, the counterweight seat 42 can be prevented from shaking up and down.

[0036] A cover plate 45 is installed at one end of the installation box 41 away from the driving device 1, and the distance between the protective cover 101 and the wiper plate 3 is greater than the height of the cover plate 45. The end of the cover plate 45 located on the inner side of the installation box 41 and the bottom wall of the installation box 41 and the lower end of the pressure plate 44 are fixedly connected with a rubber pad 451, and the rubber pad 451 can protect the installation box 41, the pressure plate 44 and the cover plate 45. The end of the cover plate 45 located on the outer side is fixedly connected with a handle 452. A locking piece 46 is provided between 45 and the installation box 41, and the locking piece 46 includes a locking column 461 movably installed on the inner side of the perforation, the locking column 461 is located between the gap of the protective cover 101, the locking column 461 is in a "T" shape, and a return spring 462 is fixedly connected between the locking column 461 and the outer wall of the installation box 41. A locking groove 463 is provided at the upper end of the cover plate 45. When the cover plate 45 is in contact with the counterweight seat 42, the locking groove 463 and the locking column 461 are docked and locked.

[0037] The working principle of the above embodiment is:

[0038] The connecting plate 412 is fixedly installed on the surface of the wiping disc 3 by fixing bolts, and the opening of the installation box 41 faces the end away from the driving device 1. After installation, when the wiping disc 3 needs to be counterweighted, the driving device 1 is stopped by the control device on the driving device 1, and the synchronous smoothing tool holder 2 stops driving the wiping disc 3 to rotate. The counterweight seat 42 to be placed is placed on the inner side of the installation box 41 through the gap between the wiping disc 3 and the protective cover 101, and the positioning groove 421 on the counterweight seat 42 is plugged with the positioning column 411, and the rotating seat 431 is rotated. The rotating seat 431 drives the fastening screw 43 to rotate and move downward, and synchronously drives the pressure plate 44, so that the pressure plate 44 limits and fixes the counterweight seat 42. After limiting and fixing, the cover plate 45 can cover the opening of the installation box 41 through the cooperation between the locking column 461 and the locking groove 463.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
