DETAILED DESCRIPTION
[0029] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.
[0030] Please refer to Figure 1-8 A mortar stone grouting tool comprises a cylindrical slurry barrel 1 and a limiting cage 6 arranged on the circumference of the slurry barrel 1, the slurry barrel 1 is arranged in the limiting cage 6, the bottom end of the slurry barrel 1 is conical and has a slurry outlet 5, a coaxially arranged piston rod 2 is arranged in the slurry barrel 1, one end of the piston rod 2 is provided with a pushing block 21, and the other end passes through an end cover 3 and is provided with a handle 4, a detachable semicircular elbow 7 is provided at the end of the slurry outlet 5, and a movably arranged trowel plate 8 is provided at the end of the semicircular elbow 7.
[0031] When in use, the bottom opening of the semicircular elbow 7 is facing the gap of the mortared stone, and then the handle 4 (piston rod 2) is pushed to make the pushing block 21 push the slurry, so that the slurry flows out from the slurry outlet 5. After flowing out, due to the blocking of the semicircular elbow 7 above, the slurry will form a semicircular slurry protrusion under the semicircular elbow 7. With the overall movement, the trowel plate 8 can smooth the slurry protrusion, and the smoothed slurry will be scraped and flow to both sides of the gap, thereby realizing grouting.
[0032] In this embodiment, the cross-section of the semicircular bend pipe 7 is in the shape of a semicircular ring, one end of the semicircular bend pipe 7 is detachably connected to the slurry outlet 5 through a flange head, and the other end of the semicircular bend pipe 7 is fixed to the bottom surface of the trowel plate 8. The semicircular bend pipe 7 is a corrugated telescopic tube and can also be a metal hose, as long as it can shield the slurry and form a columnar protrusion.
[0033] The bottom surface of the trowel plate 8 is provided with a semicircular groove 81 that cooperates with the semicircular curved pipe 7. The end of the semicircular curved pipe 7 is fixed to the inner wall of the semicircular groove 81. The end of the semicircular groove 81 is provided with a groove hole. A rolling wheel 82 for pressing the slurry is provided in the groove hole. A plurality of trowel fins 83 are provided on both sides of the rear of the rolling wheel 82. The height of the plurality of trowel fins 83 gradually decreases toward the rolling wheel 82.
[0034] When in use, the piston rod 2 is squeezed and pushed at the same time and the whole body moves. At this time, the slurry will continuously flow out to form a slurry bulge. As the whole body moves, the rolling wheel 82 will press the slurry bulge, so that the slurry can further penetrate downward and become dense, thereby increasing the depth of the grouting and improving the stability. As the trowel plate 8 moves further, the leveling fins 83 on both sides will scrape off the overflowing slurry, and the scraped slurry will stay in the potholes and can also play a filling role. Since the height of the multiple leveling fins 83 gradually decreases toward the rolling wheel 82, the multiple leveling fins 83 can achieve multiple scraping and filling of different depths, thereby improving the beauty of the grouting and the stability of both sides.
[0035] In order to ensure the fit between the trowel plate 8 and the mortared stone, a hinged damping telescopic rod 9 is also provided on the outer side of the limiting cage 6, and the output rod 91 of the damping telescopic rod 9 extends to the surface of the trowel plate 8, and the end of the output rod 91 is hinged to the trowel plate 8, and the trowel plate 8 can swing up and down through the damping telescopic rod 9; under normal circumstances, the damping telescopic rod 9 is always in a compressed state, and at this time, the output rod 91 always maintains an outward thrust to push the trowel plate, so that the trowel plate 8 fits tightly to the surface of the mortared stone, thereby increasing the density and smoothing effect of the grouting.
[0036] In this embodiment, if Fig. 9 As shown, the tool can be used vertically, in which state the trowel plate 8 is perpendicular to the slurry barrel 1; it can also be used tilted, such as Fig.10 As shown; no matter what state the damping telescopic rod 9 always pushes the trowel plate, these two usage states can meet the different usage habits of the staff and are highly practical.
[0037] Based on the above embodiment, the limit cage 6 includes an upper limit ring 61, a lower limit ring 62 and a plurality of bottom limit rings 63, and the upper limit ring 61, the lower limit ring 62 and the bottom limit ring 63 are fixedly connected by a plurality of connecting rods 64, and the plurality of connecting rods 64 are arranged in an array along the axis of the slurry barrel 1; wherein the inner diameters of the plurality of bottom limit rings 63 are relatively small, and are used to support the bottom of the conical slurry barrel; that is to say, the upper limit ring 61, the lower limit ring 62, the plurality of bottom limit rings 63 and the connecting rods 64 form a circular cage for storing the slurry barrel 1, and handrails 66 are symmetrically provided on both sides of the upper limit ring 61. When in use, the handrail can be lifted with one hand, and the piston rod can be squeezed and pushed with the other hand to satisfy the outflow of the slurry and realize the grouting.
[0038] The state of slurry outflow is as follows Fig.11 As shown in FIG. 1 , a semicircular slurry protrusion is formed between two mortar masonry stones after the slurry has just flowed out. As the trowel plate 8 moves, the protrusion will be scraped flat, as shown in FIG. Fig.12 As shown; after scraping, the rolling wheel 82 will roll the grouting position to achieve the compaction of the slurry, thereby improving the grouting strength; the leveling fins 83 on both sides will scrape off the slurry overflowed due to rolling, and the scraped slurry will stay in the potholes to play a filling role.
[0039] In order to further improve the stability of the slurry barrel 1 in the limiting cage 6, multiple groups of circumferential limiting mechanisms are provided between the multiple connecting rods 64. The multiple groups of circumferential limiting mechanism arrays are arranged around the slurry barrel 1. Each group of the circumferential limiting mechanisms includes a fixed sleeve 641 fixed on two adjacent connecting rods 64. A tensioning belt 65 is provided between the two fixed sleeves 641. The tensioning belt 65 is always in a stretched state. The multiple tensioning belts 65 tighten the slurry barrel 1 in the axial direction at the same time.
[0040] That is to say, under normal circumstances, the natural length of the tensioning belt 65 is smaller than the distance between the two connecting rods 64; after the tensioning belt 65 is installed between the two connecting rods 64, it will be stretched into a straight line and tightened; when the slurry barrel 1 is inserted, the slurry barrel 1 can push the tightened tensioning belt 65 outward, at this time, the outer wall of the slurry barrel 1 forms an arc surface contact with the tensioning belt 65, and at the same time the tensioning belt 65 will be further expanded in diameter, thereby achieving tightening.
[0041] Since the multiple groups of circumferential limiting mechanisms are arranged in a circular array, the multiple tensioning belts 65 can tighten the slurry barrel 1 toward the axis at the same time, thereby improving the stability of the slurry barrel 1 when in use.
[0042] The present invention also discloses a method for using a mortar-stone grouting tool, comprising the following steps: S1: first pull out the piston rod 2 to separate the pushing block 21 at the end from the mortar barrel 1; S2: inject grouting slurry into the mortar barrel 1, and install the piston rod 2, and after installation, screw the end cover 3 onto the port of the mortar barrel 1 through a threaded connection; S3: put the mortar barrel 1 into a limiting cage 6, so that the bottom of the mortar barrel 6 falls into a plurality of bottom limiting rings 63, while ensuring that the slurry outlet leaks out; S4: install the semicircular elbow 7, so that one end of the semicircular elbow 7 is connected to the slurry outlet 5, and the other end is connected to the semicircular groove 81 at the bottom of the trowel plate 8; S5: install the damping telescopic rod 9, and after installation, push the trowel plate 8 to check the swing; S6: lift the whole at the handrail 66, so that the bottom of the semicircular elbow 7 falls to the position to be grouting; S7: Push the handle 4 to make the push block 21 squeeze the slurry, and pull the whole to make the semicircular elbow 7 move along the grouting. At this time, the slurry flows out and is restricted by the semicircular elbow 7 to form a slurry bulge (such as Fig.11 as shown).
[0043] As the whole moves, the slurry protrusions will be smoothed (such as Fig.12 As shown), after the trowel is leveled, the rolling wheel 82 will roll the slurry in the gap, and part of the slurry will overflow after rolling, while the slurry that does not overflow will be compacted (as shown). Fig.13 As shown in the figure, the overflowing slurry is scraped and filled by the leveling fins on both sides, thereby achieving the effect of grouting, compacting and filling.
[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
