Description

Technical Field

[0001] The utility model relates to the technical field of cement paving, in particular to a scraping device for drainage ditch construction. Background Art

[0002] During the construction of the drainage ditch, when the cement-based mortar is being laid, the plane of the cement-based mortar needs to be kept horizontal, so the cement-based mortar needs to be leveled so that its surface forms a horizontal plane.

[0003] Currently, the scraping machines on the market are mostly used to scrape a single horizontal surface. However, in the process of laying cement in drainage ditches, it is usually necessary to scrape multiple planes. For example, a general drainage ditch has two inclined sides and a bottom surface. Therefore, the existing scraping machines need to scrape each surface one by one in steps, which consumes a lot of energy.

[0004] To this end, our company has proposed a device that can level multiple planes at the same time. The leveling work of multiple planes can be completed in one operation, which greatly improves the efficiency. Utility Model Content

[0005] 1. Technical issues to be solved

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a scraping device for drainage ditch construction, comprising a cement construction channel surface and a rotatable scraping roller, wherein connecting shafts are arranged on both sides of the scraping roller.

[0009] There are two sets of walking seats, and the first slot body and the second slot body are respectively opened on the upper and lower sides of the walking seats. The connecting shaft passes through the walking seat and extends into the first slot body. A rotatable link joint is also installed in the first slot body. The link joint is driven by an external motor, and the connecting shaft and the link joint are fixed by locking bolts.

[0010] The second tank body is provided with a rotatable travel wheel, and the second tank body is also provided with a sliding shaft and a plug-in shaft.

[0011] Two groups of buffer cylinders that can jump up and down are movably installed on both sides of the traveling wheel between the two groups of buffer cylinders. A buffer spring is arranged at the bottom of the inner wall of the buffer cylinder. The bottom of the plug-in shaft extends into the buffer cylinder at the corresponding position and abuts against the buffer spring. A sliding sleeve is arranged on the side of the buffer cylinder away from the traveling wheel, and the sliding sleeve is slidably connected to the sliding shaft.

[0012] As a further preference, the cement construction channel surface is concave or V-shaped.

[0013] As a further preference, a push plate is provided between the two groups of traveling seats, the push plate is located in front of the scraping roller, and the shape of the push plate is consistent with the shape of the cement construction channel surface.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] like Figure 1 , 4 As shown, the utility model provides a technical solution: a scraping device for drainage ditch construction, including a cement construction channel surface 1 and a rotatable scraping roller 2, the scraping roller 2 is shuttle-shaped, wide in the middle and narrow on both sides, the cement construction channel surface 1 is concave or V-shaped, it should be noted that the shape of the scraping roller 2 can also be other shapes, if encountering ditches of other shapes, the scraping roller 2 can be structurally designed according to the shape, and connecting shafts 3 are provided on both sides of the scraping roller 2.

[0025] like Figure 2 As shown, two sets of walking seats 4 can be installed with handrails on the walking seats 4 to facilitate workers to push them to move (not shown in the figure). The upper and lower sides of the walking seats 4 are respectively provided with a first groove body 5 and a second groove body 6. The connecting shaft 3 passes through the walking seats 4 and extends into the first groove body 5. A rotatable link joint 8 is also installed in the first groove body 5. The link joint 8 is driven by an external motor 7. The connecting shaft 3 and the link joint 8 are fixed by locking bolts 9.

[0026] like Figure 2 As shown, a rotatable travel wheel 10 is arranged in the second trough body 6 , and a sliding shaft 14 and a plug-in shaft 13 are also arranged in the second trough body 6 .

[0027] like Figure 2 As shown, two groups of buffer cylinders 11 can jump up and down, and both sides of the traveling wheel 10 are movably installed between the two groups of buffer cylinders 11. A buffer spring 12 is arranged at the bottom of the inner wall of the buffer cylinder 11, and the bottom of the plug-in shaft 13 extends to the buffer cylinder 11 at the corresponding position and abuts against the buffer spring 12. A sliding sleeve 15 is arranged on the side of the buffer cylinder 11 away from the traveling wheel 10. The sliding sleeve 15 is slidably connected with the sliding shaft 14. The sliding shaft 14 is provided to limit the traveling wheel 10 as a whole to prevent the buffer cylinder 11 and the plug-in shaft 13 from falling off. The traveling wheel 10 has a certain moving stroke in the vertical direction. When the traveling wheel 10 encounters an uneven road surface, the traveling wheel 10 automatically pushes up. At this time, the buffer spring 12 is compressed, thereby ensuring that the height of the walking seat 4 remains unchanged (consistent with the principle of the automobile shock absorption structure), thereby ensuring that the height of the scraping roller 2 remains unchanged and always fits tightly with the paved surface.

[0028] like Figure 3As shown, a push plate 16 is provided between the two groups of traveling seats 4. The push plate 16 is located in front of the scraping roller 2. The shape of the push plate 16 is consistent with the shape of the cement construction channel surface 1. The push plate 16 can push the cement accumulated in front of the scraping roller 2 to pave the way for the scraping roller 2 to scrape.

[0029] Meanwhile, the contents not described in detail in this specification belong to the prior art known to the professional and technical personnel in this field.

[0030] When in use, first install the scraping roller 2 on the traveling seat 4. During installation, insert the connecting shafts 3 on both sides into the traveling seats 4 on both sides, and fix the connecting shafts 3 and the link joints 8 by locking bolts 9. Then place the scraping roller 2 in the cement construction channel surface 1 (such as Figure 1 As shown), at this time, the travel wheel 10 is in contact with the top ground of the ditch.

[0031] Turn on the motor 7 to drive the connecting shaft 3 and the scraping roller 2 to rotate, and use the gravity of the scraping roller 2 to press on each paving surface of the cement construction channel surface 1. The scraping roller 2 flattens each paving surface during the rotation process. The staff only needs to stand on the ground and push the walking seat 4 to move to complete the scraping work of the entire ditch.

[0032] To summarize, the scraping device for drainage ditch construction is provided with a scraping roller that is consistent with the shape of the ditch paving surface. During the rolling process, the scraping roller is closely fitted with multiple planes of the ditch, so that the scraping work of multiple planes can be achieved with the rolling of only one scraping roller. Furthermore, by providing an adaptive walking seat, the staff only needs to stand on the outside of the ditch and push the walking seat to move, so as to drive the scraping roller to work, saving physical effort. Furthermore, in order to overcome the adverse effect of the unevenness of the ditch surface on the movement trajectory of the scraping roller, the traveling wheel is designed as a self-following structure, and the traveling wheel can automatically adjust the height following the uneven road surface, thereby ensuring that the scraping roller is in close contact with each cement paving surface, thereby ensuring the scraping quality.
