Description

Technical Field

[0001] This utility model relates to the field of drainage ditch construction, and in particular to a drainage ditch excavation tool for excavators and an excavator. Background Technology

[0002] In roadbed engineering projects such as highways and railways, drainage ditches are crucial drainage facilities, and their construction quality directly affects the stability and service life of the roadbed. Traditional drainage ditch excavation often employs ordinary excavators combined with manual trimming, which presents the following problems: Low construction efficiency: Manual excavation is labor-intensive and slow. Although ordinary excavators can improve efficiency, they need to be adjusted multiple times to reach the design dimensions, resulting in a long overall construction period. Poor alignment control: Traditional methods make it difficult to accurately control the alignment and elevation of the drainage ditch, which can easily lead to problems such as bending and uneven depth, affecting the drainage effect; Insufficient dimensional accuracy: Large deviations in trench dimensions lead to significant material waste during subsequent concrete pouring, increasing construction costs; Low construction safety: Frequent cross-operation between machinery and personnel poses certain safety hazards.

[0003] Therefore, there is an urgent need for a new type of excavation equipment that can improve excavation efficiency, ensure construction quality, and reduce safety risks. Utility Model Content

[0004] The purpose of this utility model is to overcome the problems of low efficiency, poor alignment control, inaccurate dimensions and insufficient safety of traditional drainage ditch excavation methods, and to provide a drainage ditch excavation tool and excavator for excavators.

[0005] In a first aspect, the present invention provides a drainage ditch excavation tool for an excavator, including a bucket body, the cross-sectional shape of which is adapted to the end face shape of the drainage ditch to be excavated, and limiting plates provided on both sides of the top surface of the bucket body, the two limiting plates being used to abut against the ground on both sides of the drainage ditch.

[0006] This utility model relates to a drainage ditch excavation tool for excavators. In use, the bucket is connected to the excavator, and the excavator drives the bucket to move along the length of the drainage ditch, thereby achieving one-time formation of the drainage ditch. During the process, the limiting plate abuts against the ground on both sides of the drainage ditch, which can realize the height limit of the bucket and the line guidance during the excavation process, effectively preventing over-excavation and line deviation, and ensuring the structural dimensions and linear accuracy of the ditch.

[0007] Preferably, the bucket body includes a baffle and a surrounding plate mechanism, the surrounding plate mechanism being arranged around the edge of the baffle.

[0008] The baffle and enclosure mechanism form a box-shaped component, which facilitates the removal of soil during the excavation of the drainage ditch.

[0009] Preferably, the enclosure mechanism includes a top plate and a bottom plate arranged parallel to each other, side plates are respectively provided on both sides of the top plate, the two side plates are respectively connected to both sides of the bottom plate, the top plate, the bottom plate and the two side plates are enclosed to form a trapezoidal structure, and the limiting plate is provided on the top of the top plate.

[0010] The enclosure mechanism is specifically designed as an isosceles trapezoidal structure, which perfectly matches the cross-section of common trapezoidal drainage ditches, achieving one-time molding without the need for secondary adjustments, greatly improving excavation efficiency and dimensional accuracy.

[0011] Preferably, the top of the top plate is provided with a connecting seat, the connecting seat includes two oppositely arranged fixing plates, and the two fixing plates are provided with mounting holes respectively.

[0012] By setting up a standard connecting seat, this tooling can be quickly and easily connected to the bucket linkage of the excavator via a pin shaft, achieving standardization and quick replacement, and improving equipment utilization.

[0013] Preferably, the mounting hole has an annular boss at its edge.

[0014] The annular boss can effectively increase the structural strength around the mounting hole, prevent the hole wall from deforming or tearing due to long-term stress on the pin, and improve the stability and safety of the connection.

[0015] Preferably, the baffle is provided with a plurality of exhaust holes.

[0016] During the excavation process, the air inside the bucket can be quickly discharged through the vent, effectively avoiding the problem of soil not being able to enter the bucket smoothly due to air resistance or the creation of an "air cushion" effect, thus ensuring the smoothness and efficiency of the excavation process.

[0017] Preferably, the enclosure mechanism is provided with a first reinforcing rib, the bottom of the first reinforcing rib is connected to the baffle, and the top plate and the bottom plate are respectively connected to the two sides of the first reinforcing rib.

[0018] The first reinforcing rib forms a strong support between the top plate and the bottom plate, effectively transferring the impact force borne by the bottom plate during excavation to the top plate and the entire bucket body, significantly enhancing the load-bearing capacity and impact resistance of the bottom of the bucket body, and preventing the bottom plate from deforming.

[0019] Preferably, the enclosure mechanism is provided with two second reinforcing ribs, which are respectively located near the connection between the two side plates and the top plate. The bottom of the second reinforcing rib is connected to the baffle, and the two sides of the second reinforcing rib are respectively connected to the top plate and the side plate.

[0020] The second reinforcing rib strengthens the connection between the side plate and the top plate where stress is most concentrated, dispersing the lateral excavation resistance to the entire bucket body, greatly improving the torsional rigidity of the tooling, and ensuring that the limit plates on both sides will not shift when under stress, thereby strictly guaranteeing the width of the excavated trench.

[0021] Preferably, a third reinforcing rib is provided on the inner side of the top plate, and the third reinforcing rib is arranged along the length direction of the top plate.

[0022] Because the top plate is a trapezoidal structure with the long side, the third reinforcing rib acts as the longitudinal beam of the top plate, which greatly improves the bending strength of the top plate along the length direction, prevents it from sinking and deforming due to the stress in the middle, ensures the flatness and stability of the foundation plane connected to the excavator, and further guarantees the construction quality.

[0023] In a second aspect, the present invention provides an excavator, including an excavator body and a drainage ditch excavation tool for an excavator as described above, wherein the bucket is connected to the bucket linkage of the excavator body.

[0024] This utility model relates to an excavator. The original bucket is removed from the excavator body, and the bucket is connected to the bucket linkage of the excavator body. Next, surveyors mark the centerline and sidelines of the drainage ditch on the ground. The operator manipulates the excavator body to position the tooling, ensuring the limit plates on both sides are positioned above the marked excavation lines. Then, the excavator body's bucket cylinder is operated to drive the tooling vertically downwards, with the limit plates positioned on the ground on both sides of the drainage ditch to prevent over-excavation. Subsequently, the excavator body is operated to move the tooling horizontally along the drainage ditch's direction, completing the excavation of one section of the ditch. Finally, after completing one section, the excavator body is operated to raise the boom and unload the soil from the tooling into a matching dump truck. The excavator body then reverses, and the above steps are repeated to continuously excavate the next section of the ditch until the entire section is completed.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a drainage ditch excavation tool for excavators. By setting the cross-sectional shape of the bucket body to match the end face shape of the drainage ditch to be excavated, it can achieve one-time precise excavation, completely avoiding the problem of concrete waste caused by dimensional deviation in traditional methods, and significantly improving construction quality and economy. 2. This utility model provides a drainage ditch excavation tool for excavators. By setting limiting plates on both sides of the top surface of the bucket to abut against the ground, the height of the bucket and the alignment guidance can be realized during the excavation process, effectively preventing over-excavation and alignment deviation, and ensuring the structural dimensions and linear accuracy of the trench. 3. This utility model provides a drainage ditch excavation tool for excavators. By integrating a special bucket and a limiting structure, it enables excavators to quickly change equipment and carry out efficient and continuous excavation operations, which greatly reduces the amount of manual trimming work, improves construction efficiency, and reduces on-site safety risks.

[0033] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides a drainage ditch excavation tool for an excavator, including a bucket body 1. The cross-sectional shape of the bucket body 1 is adapted to the end face shape of the drainage ditch to be excavated. Limiting plates are provided on both sides of the top surface of the bucket body 1, and the two limiting plates are respectively used to abut against the ground on both sides of the drainage ditch.

[0034] In one or more implementations, such as Figure 1 As shown, the bucket body 1 may include a baffle 11 and a surrounding plate mechanism 12. The surrounding plate mechanism 12 is arranged around the baffle 11, and the two enclose each other to form a box-shaped component, which can bring out the soil during the excavation process.

[0035] In optional implementations, such as Figure 1 As shown, the enclosure mechanism 12 may include a top plate 121, a bottom plate 122 and two side plates 123. The top plate 121, the bottom plate 122 and the two side plates 123 enclose an isosceles trapezoid. The limiting plates are set on both sides of the top surface of the top plate 121. The cross-sectional shape of the enclosure mechanism 12 matches the common trapezoidal drainage ditch cross-section, realizing the one-time forming of the drainage outlet.

[0036] In optional implementations, such as Figure 1 As shown, the top plate 121 is provided with a connecting seat, which includes two oppositely arranged fixing plates 31. The two fixing plates 31 are provided with mounting holes 311, which enables the tooling to be quickly and conveniently connected to the bucket connecting rod 41 of the excavator by a pin shaft, realizing universality and quick replacement, and improving equipment utilization.

[0037] In optional implementations, such as Figure 1 As shown, an annular boss 312 can be provided on the edge of the mounting hole 311.

[0038] In optional implementations, such as Figure 1 As shown, several vent holes 111 can be provided on the baffle 11. During the excavation process, the air inside the bucket 1 can be quickly discharged through the vent holes 111, which effectively avoids the problem of soil not being able to enter the bucket smoothly due to air resistance or the generation of an "air cushion" effect, and ensures the smoothness and efficiency of the excavation process.

[0039] In one or more implementations, such as Figure 1 As shown, a first reinforcing rib 1201, a second reinforcing rib 1202, and a third reinforcing rib 1203 may also be provided inside the enclosure mechanism 12.

The first reinforcing rib 1201 forms a strong support between the top plate 121 and the bottom plate 122, effectively transferring the impact force borne by the bottom plate 122 during excavation to the top plate 121 and the entire bucket body 1, significantly enhancing the pressure bearing capacity and impact resistance of the bottom of the bucket body 1, and preventing the bottom plate 122 from deforming.

[0041] The second reinforcing rib 1202 consists of two ribs, which are respectively located near the connection between the two side plates 123 and the top plate 121. The bottom of the second reinforcing rib 1202 is connected to the baffle 11, and the two sides of the second reinforcing rib 1202 are respectively connected to the top plate 121 and the side plates 123. The second reinforcing rib 1202 strengthens the connection between the side plate 123 and the top plate 121 where the stress is most concentrated, dispersing the lateral excavation resistance to the entire bucket body 1, greatly improving the torsional stiffness of the tooling, and ensuring that the limit plates on both sides will not shift when subjected to force, thereby strictly guaranteeing the width of the excavated trench.

[0042] The third reinforcing rib 1203 is set on the inner side of the top plate 121 along the length of the top plate 121, which greatly improves the bending strength of the top plate 121 along the length, prevents it from sinking and deforming due to the force in the middle, ensures the flatness and stability of the foundation plane connected to the excavator, and further guarantees the construction quality.

[0043] Example 2 like Figure 1 and Figure 3 As shown, this embodiment provides an excavator, including an excavator body 4 and a drainage ditch excavation tool for an excavator as described in Embodiment 1, wherein the bucket body 1 is connected to the bucket linkage 41 of the excavator body 4.

[0044] In use, the original bucket of the excavator body 4 is removed, and the bucket body 1 is connected to the bucket linkage 41 of the excavator body 4. Next, the surveyor marks the center line and side line of the drainage ditch on the ground. The operator manipulates the excavator body 4 to position the tooling, so that the limit plates on both sides are positioned above the marked excavation line. Then, the excavator body 4's bucket cylinder is operated to drive the tooling vertically downward, with the limit plates positioned on the ground on both sides of the drainage ditch to ensure that over-excavation does not occur. Subsequently, the excavator body 4 is operated to move the tooling horizontally along the direction of the drainage ditch line to complete the excavation and shaping of a section of the ditch. Finally, after completing a section of excavation, the excavator body 4 is operated to lift the boom and dump the soil in the tooling into the matching dump truck. The excavator body 4 is then reversed, and the above steps are repeated to continuously excavate the next section of the ditch until all sections are completed.
