Description

Technical Field

[0001] The utility model relates to the technical field of trowel machines, in particular to a trowel machine grinding disc assembly which is easy to load and unload. Background Art

[0002] The trowel machine is also called a finishing machine. Its main structure is a trowel rotor driven by a gasoline engine. A trowel is installed on the bottom of the cross in the middle of the rotor. The tilt direction of the trowel is consistent with the rotation direction of the rotor. The gasoline engine drives the V-belt to rotate the trowel rotor. The surface constructed by it is smoother and flatter than the surface constructed by manual labor. It can greatly improve the density and wear resistance of the concrete surface, and improve the work efficiency by more than times compared with manual labor.

[0003] In the prior art, when a trowel machine is used to smooth the floor, it generally first uses a grinding disc for rough grinding. After the rough grinding is completed, the grinding disc is removed and then fine grinding is performed with a spatula. When replacing the grinding disc, multiple people are required to lift the trowel machine to replace the grinding disc. Since the entire trowel machine is heavy, replacing the grinding disc is time-consuming and laborious. In addition, the grinding disc is usually installed on the machine by bolts, and installation and disassembly are relatively troublesome. Utility Model Content

[0027] In combination with the above structure, the device is moved by pushing the push rod 2, and the sleeve rod 4 is driven to rotate by the power mechanism 1, so that the grinding disc 6 rotates to achieve the finishing of the concrete.

[0028] Combined with Figure 2 and attached Figure 3 The sleeve rod 4 is laterally plugged with a bolt 11, and the output end at the lower end of the power mechanism 1 is provided with a through hole 101 through which the bolt 11 passes laterally, so as to facilitate the installation and disassembly of the sleeve rod 4.

[0029] Combined with Figure 4 The positioning assembly 8 includes a sleeve 12 screwed to one side of the connecting plate 5, a positioning rod 13 vertically passes through the inner end of the sleeve 12, and a slider 14 slidably connected in the sleeve 12 is provided on the positioning rod 13. A spring 15 is sleeved on the positioning rod 13 between the inner end of the sleeve 12 and the slider 14, and a knob 16 is connected to the outer end of the positioning rod 13.

[0030] Combined with Figure 2 and attached Figure 5 The connecting plate 5 and the L-shaped connecting plate 7 are respectively provided with a through hole 1 501 and a through hole 2 701 through which the positioning rod 13 passes.

[0031] In combination with the above structure, by inserting the positioning rod 13 on the through hole 1 501 and the through hole 2 701, the position of the L-shaped connecting plate 7 is fixed, that is, the position of the grinding wheel 6 is fixed. When the grinding wheel 6 needs to be removed, it is necessary to pull and rotate the knob 16 to disengage the positioning rod 13 from the through hole 2 701, so that the grinding wheel 6 is easy to install and remove.

[0032] Combined with Figure 4 The end of the sleeve 12 is provided with a threaded tube 17, and the two ends of the positioning rod 13 between the slider 14 and the knob 16 are respectively provided with a threaded portion 1301 and a threaded portion 1302 threadedly connected to the threaded tube 17.

There is no need for multiple people to lift the trowel to replace the grinding disc 6, which is easy to use.

[0037] The specific usage is as follows:

[0038] By pushing the push rod 2, the device is moved to a suitable position for use through multiple pulleys 21; when the grinding disc 6 needs to be disassembled and replaced, the lifting component 10, that is, the hand-cranked turntable 20, is rotated to rotate the threaded rod 19, so that the threaded rod 19 drives the pulley 21 to descend, thereby raising the entire device, and by rotating and pulling the knob 16, the threaded portion 1302 is disengaged from the threaded tube 17, so that the positioning rod 13 is disengaged from the through hole 701, and then the knob 16 is rotated again to make the threaded portion 1301 threadedly connected with the threaded tube 17, and the position of the positioning rod 13 is fixed, and the grinding disc 6 can be taken out; put in the replaced grinding disc 6, and when the threaded portion 1302 is threadedly connected with the threaded tube 17 by adjusting the knob 16, the positioning rod 13 is kept inserted into the through hole 701, so that the position of the grinding disc 6 is fixed, and the grinding disc 6 can be disassembled and replaced, and there is no need for multiple people to lift the trowel machine, which is convenient to use.

[0039] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
