Description

Technical Field

[0001] The utility model relates to the field of construction equipment, in particular to an auxiliary device for removing slag from an excavator. Background Art

[0002] During the construction process, it is often necessary to demolish some original facility structures and clean up the site before new construction can be carried out on the original plot. During the demolition of the original facilities, generally, an excavator is used in cooperation with a breaker and other devices to break the original facilities and obstacles. After the large obstacles are broken, the broken residues are gradually cleaned out to meet the requirements of construction.

[0003] However, in the existing construction process, for some obstacles in special narrow structures, such as column pile structures, although the excavator can break the obstacles inside them through the breaker, the broken residues fall into the steel bars of the column piles and are difficult to clean out in time. The large excavator bucket cannot also penetrate into the narrow space structure to dig and transfer the residues. Workers often need to enter the site to dig out the residues little by little with shovels, and then clean them onto the trolley and transfer them out little by little. This not only wastes a large amount of labor costs but also seriously slows down the progress of construction cleaning. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is: how to conveniently clean out the broken residues in a narrow space. To solve the above technical problem, the utility model provides an auxiliary device for removing slag from an excavator, which includes a slag removal main board. A first mounting member and a second mounting member are arranged on the front surface of the slag removal main board. Both the first mounting member and the second mounting member are connected to the breaker at the end of the excavator. The first mounting member is provided with a first mounting hole, and the second mounting member is provided with a second mounting hole. The end of the breaker sequentially passes through the first mounting hole and the second mounting hole, so that the breaker is clamped and fixed with the first mounting member and the second mounting member.

[0005] Preferably, the first mounting member includes a mounting plate welded and fixed to the slag removal main board. The first mounting hole is opened on the plate surface of the mounting plate. First side plates are symmetrically arranged on both sides of the mounting plate along a first direction, wherein the first direction is perpendicular to the axis of the first mounting hole.

[0006] Preferably, the second mounting member includes an annular plate whose outer peripheral wall is welded and fixed to the front surface of the slag removal main board. The second mounting hole is a through hole in the middle of the annular plate.

[0007] Preferably, the axis of the first mounting hole is parallel to the axis of the second mounting hole, and the projections of the axes of the first mounting hole and the second mounting hole on the slag removal main board coincide.

[0008] Preferably, second side plates are provided on both sides of the slag cleaning main board along the first direction, and one end of each second side plate away from the second mounting member is flush with the end of the slag cleaning main board.

[0009] Preferably, a chamfer is provided at one end of each second side plate away from the second mounting member.

[0010] Preferably, a limiting member is further included. The limiting member is U-shaped. Limiting holes are provided at two ends of the slag cleaning main board corresponding to the limiting member. The ends of the limiting member pass through the limiting holes and are connected with limiting nuts.

[0011] Compared with the prior art, the beneficial effects of an auxiliary device for cleaning slag of an excavator provided in an embodiment of the present invention are as follows:

[0012] In the present invention, when facing the crushing and cleaning work in a narrow position, the crushing head of the excavator can pass through the first mounting hole and the second mounting hole in sequence, and the slag cleaning auxiliary device is stably clamped and fixed on the original crushing head through the first mounting member and the second mounting member. As the crushing head presses down to crush the obstacle, the clamping between the slag cleaning auxiliary device and the crushing head becomes more stable. The setting of the slag cleaning main board can, on the one hand, increase the force-bearing area and crushing range of the crushed obstacle, thereby accelerating the crushing efficiency of the obstacle; on the other hand, when the obstacle is crushed, compared with the traditional conical crushing head, the cross-sectional area of the slag cleaning main board is larger, and it can well scrape out the crushed residues in the pile column structure or narrow structure, thus facilitating the cleaning and transportation of the residues without manual excavation, saving labor costs and having higher slag cleaning efficiency.

[0022] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0023] As Figures 1 to 4 shown, a preferred embodiment of the present invention provides an auxiliary device for cleaning slag of an excavator, which includes a slag cleaning main board 1. A first mounting member 2 and a second mounting member 3 are provided on the front surface of the slag cleaning main board 1. Both the first mounting member 2 and the second mounting member 3 are connected to the crushing head 5 at the end of the excavator; the first mounting member 2 is provided with a first mounting hole 21, the second mounting member 3 is provided with a second mounting hole 31, and the end of the crushing head 5 sequentially passes through the first mounting hole 21 and the second mounting hole 31, so that the crushing head 5 is clamped and fixed to the first mounting member 2 and the second mounting member 3.

[0024] Specifically, the bottom of the traditional crushing head 5 is mostly conical, and the excavator applies a driving force to break the obstacles. After the obstacles are broken, the broken residues are generally dug and transferred by the bucket of the excavator. For the residues in some narrow parts, such as pile column structures, most of the broken concrete residues fall into the annular steel bar framework. For this part of the residues, the bucket of the excavator is too large to dig and transfer the residues deep into it. In the traditional solution, workers can only dig out the residues from the narrow space little by little with a shovel, and the transfer efficiency is very low, and the labor cost is too high. In this embodiment, an auxiliary device for cleaning slag is additionally fixed on the basis of the original crushing head 5. The auxiliary device for cleaning slag is clamped and fixed to the crushing head 5 through the first mounting member 2 and the second mounting member 3. The slag cleaning main board 1 in the auxiliary device for cleaning slag can increase the crushing area and range compared with the original crushing head 5, thereby improving the efficiency of breaking obstacles. When the obstacles are broken, for the broken residues falling in the narrow space, the slag cleaning main board 1 can act as a shovel, and the excavator applies power to dig out or dig out the residues in the narrow space to between the narrow spaces, eliminating the cost and low efficiency of manually cleaning the residues from the narrow space. The setting of the auxiliary device for cleaning slag improves the overall crushing and cleaning efficiency and also reduces the labor cost of cleaning slag. Among them, the slag cleaning main board 1 can be processed and manufactured from waste steel plates recycled on the construction site, with lower production costs and more simplicity; in addition, a chamfer can be set on the end face of the slag cleaning main board 1 for contacting the obstacles for crushing to enhance the crushing ability of the obstacles.

[0025] In some embodiments, the first mounting member 2 includes a mounting plate 22 welded and fixed to the slag cleaning main board 1. The first mounting hole 21 is formed in the plate surface of the mounting plate 22. First side plates 23 are symmetrically arranged on both sides of the mounting plate 22 along a first direction, where the first direction is perpendicular to the axis of the first mounting hole 21.

[0026] Specifically, when the original breaker head 5 is installed at the end of the excavator, there is a structure in the fixed part, and the mounting plate 22 can support this fixed part. The two relatively arranged first side plates 23 can also limit and protect the structure of this fixed part. After the end of the breaker head 5 passes through the first mounting hole 21, it continues to pass downward through the second mounting hole 31. By setting the relative positions and orientations of the first mounting member 2 and the second mounting member 3, the breaker head 5 is clamped between the first mounting member 2 to achieve fixation. Further, the first mounting member 2 can be made of a discarded I-beam. By forming the first mounting hole 21 in the middle of the I-beam and welding and fixing the I-beam to the slag cleaning main board 1, the connection structure between the first mounting member 2 and the slag cleaning main board 1 is realized.

[0027] In some embodiments, the second mounting member 3 includes an annular plate 32 whose outer peripheral wall is welded and fixed to the front surface of the slag cleaning main board 1. The second mounting hole 31 is a through hole in the middle of the annular plate 32.

[0028] Specifically, the annular plate 32 can be made of a discarded steel pipe on the construction site. Select a steel pipe with a suitable inner diameter size, cut a section of it and weld it to the slag cleaning main board 1. The middle pipe of the steel pipe serves as the second mounting hole 31. The end of the breaker head 5 passes through the second mounting hole 31 and abuts against the slag cleaning main board 1, thereby realizing a stable clamping connection between the breaker head 5 and the second mounting member 3.

[0029] In some embodiments, the axis of the first mounting hole 21 is parallel to the axis of the second mounting hole 31, and the projections of the axes of the first mounting hole 21 and the second mounting hole 31 on the slag cleaning main board 1 coincide.

[0030] Specifically, the axes of the first mounting hole 21 and the second mounting hole 31 are parallel, which facilitates the insertion of the crushing head 5 into the first mounting hole 21 and the second mounting hole 31 in sequence, enabling the slag cleaning auxiliary device to be better clamped and fixed on the crushing head 5. The coincidence of the projections of the axes of the two mounting holes on the slag cleaning main board 1 means that there is no positional deviation between the two mounting holes in the first direction, but only a positional deviation in the direction perpendicular to the board surface of the slag cleaning main board 1. On the one hand, it allows the crushing head 5 to smoothly pass through the first mounting hole 21 and the second mounting hole 31 in sequence. On the other hand, since there is a positional deviation between the axis of the first mounting hole 21 and the axis of the second mounting hole 31 in the direction perpendicular to the board surface of the slag cleaning main board 1, especially the axis of the second mounting hole 31 is closer to the board surface of the slag cleaning main board 1 than the axis of the first mounting hole 21. When the crushing head 5 passes through the first mounting hole 21 and the second mounting hole 31 in sequence, the axis of the crushing head 5 is inclined compared to the axes of the first mounting hole 21 and the second mounting hole 31, and its end will abut against the front surface of the slag cleaning main board 1, thereby realizing the clamping and fixing of the first mounting member 2 and the second mounting member 3 on the crushing head 5. And as the crushing process progresses, under the impact reaction, the slag cleaning auxiliary device has a tendency to move upward, further making the connection between the crushing head 5 and the first mounting member 2 and the second mounting member 3 tighter and more stable.

[0031] In some embodiments, second side plates 11 are provided on both sides of the slag cleaning main board 1 along the first direction, and the ends of the second side plates 11 away from the second mounting member 3 are flush with the ends of the slag cleaning main board 1.

[0032] Specifically, when scraping the residue out of the narrow space, the second side plates 11 can form a concave-shaped area with the slag cleaning main board 1, facilitating the gathering and scraping of the residue. During the process of scraping the residue, it is avoided that the residue is far from the board surface of the slag cleaning main board 1, improving the cleaning efficiency of the residue.

[0033] In some embodiments, chamfers are provided at the ends of the second side plates 11 away from the second mounting member 3. Specifically, the chamfers provided at the ends of the second side plates 11 are convenient for crushing obstacles on the one hand, and on the other hand, when cleaning the residue, it is also convenient for the slag cleaning main board 1 to be inserted into the residue pile to scrape out as much residue as possible.

[0034] In some embodiments, the slag cleaning auxiliary device of the excavator further includes a limiting member 4. The limiting member 4 is U-shaped. The slag cleaning main board 1 is provided with limiting holes 12 corresponding to the two ends of the limiting member 4. The ends of the limiting member 4 pass through the limiting holes 12 and are connected with limiting nuts 41.

[0035] Specifically, during actual use, a U-shaped limiting member 4 can be set. The cross-section of the limiting member 4 can be cylindrical. The end of the limiting member 4 passes through the slag cleaning main board 1 and is locked and fixed by a nut. The cross-section of the limiting member 4 can also be square. Openings are made on the limiting member 4 corresponding to the limiting holes 12 on the slag cleaning main board 1, and then locked and fixed by bolts and nuts. The limiting member 4 is connected to the slag cleaning main board 1 through structures such as nuts, and then the nuts are tightened to increase the pressure between the limiting member 4 and the crushing head 5, thereby increasing the friction force and making the connection between the slag cleaning auxiliary device and the crushing head 5 more stable. Similarly, the limiting member 4 can also locally use the discarded steel bars with threads at the ends on the construction site, and then be welded and bent for use.

[0036] In summary, the embodiment of the present utility model provides an auxiliary device for cleaning slag of an excavator. By using the first mounting member 2, the second mounting member 3, and the limiting member 4, the slag cleaning auxiliary device is stably mounted on the original crushing head 5. On the one hand, the slag cleaning main board 1 can expand the crushing range and area of obstacles, improving the crushing efficiency; on the other hand, for the crushing residues in a narrow space, the slag cleaning main board 1 can quickly and conveniently scoop out the residues in the narrow space, facilitating the subsequent transfer of the residues, and the slag cleaning efficiency will also be higher, and it also eliminates the trouble of manually digging out the residues in the narrow space in the traditional solution.

[0037] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
