[0001] This application relates to the field of construction equipment technology, and in particular to a cleaning component, a bucket, an excavator, and a construction method. Background Technology

[0002] After the pile foundation construction is completed, earthwork excavation is required to clear the soil around the pile and the soil between the piles to expose the top of the pile for subsequent structural construction.

[0003] During pile foundation construction, the soil around the piles is compressed and consolidates in the depressions between the piles, forming inter-pile soil. Because the inter-pile soil is located in the depressions between the piles, it is difficult to clean it completely without damaging the piles using existing excavators. Summary of the Invention

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0028] In the description of this application, it should be understood that the terms "first", "second", "third" and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0029] Please see Figure 1 and combined Figures 7 to 9 as well as Figures 12 to 15 This application provides a cleaning component 100, including a frame 120, a scraping component 140, and an elastic component 160.

[0030] The frame 120 can be installed on the back 3214 of the bucket 300.

[0031] The scraping component 140 is rotatably connected to the frame 120; when the frame 120 is installed on the back 3214 of the bucket 300, the scraping component 140 can extend into the recess 23 between the piles; when the scraping component 140 applies a first force to the object to be cleaned located in the recess 23 between the piles, the scraping component 140 rotates relative to the frame 120 based on the reaction force of the first force.

[0032] The elastic component 160 is connected at one end to the frame 120 and at the other end to the scraping component 140, and is used to limit the rotational range of the scraping component 140 through elastic force.

[0033] It is understood that in this embodiment of the application, the bucket 300 has an opening 3212 and a back 3214. The opening 3212 is used to accommodate the material to be cleaned, and the back 3214 is the side facing away from the opening 3212. The recess 23 between piles can be the recess 23 between piles of the pile foundation 21, or it can be other types of recesses 23 between piles. The material to be cleaned can be earth or other types of objects. When the recess 23 between piles is the recess 23 between piles of the pile foundation 21, and the material to be cleaned is earth, the material to be cleaned located in the recess 23 between piles is referred to as the soil between piles 25.

[0034] It is understood that in this embodiment of the application, after the frame 120 is installed on the back 3214 of the bucket 300, the scraping component 140 rotates relative to the frame 120 within a certain range. That is, the scraping component 140 rotates relative to the bucket 300 within a certain range to achieve a soft connection between the scraping component 140 and the object to be cleaned, thereby cleaning the object to be cleaned in the recess 23 between the piles without damaging the pile body 21. When the object to be cleaned in the recess 23 between the piles is the soil 25 between the piles, it is possible to clean the soil 25 between the piles without damaging the pile body.

[0035] Understandably, for ease of explanation, the following description will use the clearing of soil between piles 25 as an example.

[0036] Understandably, please refer to Figures 12 to 14 The pile body 21 is the core component of the pile foundation 201. The pile body 21 refers to a single column driven or buried in the ground. The pile foundation 201 refers to the entire deep foundation system composed of multiple pile bodies 21, a pile cap connecting all the pile tops, and superstructure columns or piers.

[0037] In some embodiments, please refer to Figure 1 and Figure 2 The frame 120 includes a first shaft 121 and a second shaft 123 arranged along a first direction.

[0038] The scraping component 140 includes a connecting body 141, a third shaft 143, and at least one scraper 145; one end of the connecting body 141 is rotatably connected to the second shaft 123, and the other end is connected to at least one scraper 145; the third shaft 143 is disposed along a first direction on the connecting body 141 and is located between the second shaft 123 and the at least one scraper 145.

[0039] One end of the elastic component 160 is connected to the first shaft 121, and the other end is connected to the third shaft 143.

[0040] Understandably, please combine Figures 12 to 15 When the scraper 145 comes into contact with the soil 25 between the piles, a first force is applied to the soil 25 between the piles. The scraper 145 is subjected to a reaction force based on the first force, which drives the scraping component 140. The scraping component 140 includes the scraper 145, the connecting body 141 and the third shaft 143, and rotates around the second shaft 123.

[0041] Due to the elastic force of the elastic component 160, when the third shaft 143 compresses the elastic component 160, the elastic component 160 will apply a force opposite to the compression to the third shaft 143. When the third shaft 143 stretches the elastic component 160, the elastic component 160 will apply a force opposite to the stretching direction to the third shaft 143. This limits the rotation range of the third shaft 143 around the second shaft 123 to a certain range, thereby limiting the rotation range of the scraper 145 around the second shaft 123 to a certain range. This achieves a soft connection between the scraper 145 and the frame 120, enabling the soil 25 between the piles to be cleaned without damaging the pile body.

[0042] It is also understandable that you should combine this with... Figure 10 The bucket 300 includes a bucket body 321 and a digging blade 323 disposed on the bucket body 321. The digging blade 323 is the part that directly contacts the object to be dug. Please refer to... Figure 8 When the cleaning assembly 100 is installed on the bucket 300, the orientation of the first shaft 121, the second shaft 123, and the third shaft 143 is the same as the distribution orientation of the digging blades 323 on the bucket body 321 when the digging blades 323 are installed on the bucket body 321. When the digging blades 323 are distributed along the first direction H1 on the bucket body 321, the first shaft 121, the second shaft 123, and the third shaft 143 are also distributed along the first direction H1 on the bucket body 321. When the digging blades 323 are distributed along the first direction H1 on the bucket body 321, the digging direction of the digging blades 323 is perpendicular to the first direction H1.

[0043] For example, there may be at least one scraper 145, or there may be only one scraper 145, or there may be two or more scrapers 145.

[0044] In some embodiments, when the number of scrapers 145 is two or more, the scrapers 145 are spaced apart along the first direction, and the distance between two adjacent scrapers 145 is adapted to the distance between the recesses 23 between two adjacent piles.

[0045] It is understandable that when there are two or more scrapers 145, at least one scraper 145 is set at intervals along the first direction, and the distance between two adjacent scrapers 145 is adapted to the distance between two adjacent pile depressions 23, so that the soil 25 between at least one pile depression 23 can be cleaned at the same time, thereby improving the cleaning efficiency of the soil 25 between piles.

[0046] In some embodiments, please refer to Figure 4 and Figure 5 The scraping component 140 also includes an adjusting plate 147 and at least one adjusting screw 149.

[0047] The adjusting plate 147 is provided with a locking groove 147a; at least one scraper 145 includes a plate body 1454 and a locking part 1452 connected to each other; at least one scraper 145 is connected to the adjusting plate 147 in such a way that the locking part 1452 is provided in the locking groove 147a.

[0048] The adjusting plate 147 is also provided with at least one mounting hole 147b, which communicates with the engaging groove 147a; the at least one mounting hole 147b is threadedly connected to at least one adjusting screw 149.

[0049] When at least one scraper 145 is connected to the adjusting plate 147 by means of a locking part 1452 disposed in the locking groove 147a, adjusting screws 149 are installed in the mounting holes 147b located on both sides of each scraper 145 to fix each scraper 145.

[0050] It is understandable that by providing a locking groove 147a, at least one mounting hole 147b, and at least one adjusting screw 149 in the adjusting plate 147, and using at least one scraper 145 with a locking portion 1452, at least one scraper 145 is connected to the adjusting plate 147 by having the locking portion 1452 disposed in the locking groove 147a. The adjusting screws 149 are then installed in the mounting holes 147b located on both sides of each scraper 145 to fix them in place. It is readily understood that this structure also allows for adjustment of the position of at least one scraper 145 relative to the locking groove 147a, as well as adjustment of the relative positions of at least one scraper 145 to each other.

[0051] For example, please refer to Figures 12 to 15 The shape and size of the scraper 145 plate 1454 are adapted to the shape and size of the recess 23 between the piles.

[0052] For example, the scraper 145's plate body 1454 can be shaped such that its size gradually decreases from the end near the engaging portion 1452 to the end away from the engaging portion 1452. This shape facilitates easier insertion into the recess 23 between piles and easier application of force to the soil 25 between piles, thus facilitating the rapid cleaning of the soil 25 between piles. For example, the side of the scraper 145's plate body 1454 away from the engaging portion 1452 may be triangular. Or, for another example, the side of the scraper 145's plate body 1454 away from the engaging portion 1452 may be an isosceles triangle. In some embodiments, please refer to Figure 6 and combined Figures 7 to 10 The frame 120 also includes: a fourth shaft 125, a buckle 122, a first connecting rod 127, and a second connecting rod 129.

[0053] The fourth shaft 125 is used to connect with the lug 325 provided on the bucket 300 in a through-type manner.

[0054] The buckle 122 is used to engage with the bucket teeth 3232 on the bucket 300.

[0055] The first connecting rod 127 is connected at one end to the fourth shaft 125 and at the other end to the first shaft 121.

[0056] The second connecting rod 129 has one end connected to the buckle 122 and the other end connected to the first shaft 121. The second shaft 123 is disposed on the second connecting rod 129.

[0057] For example, please refer to 7. Figure 9 and Figure 10 The buckle 122 is provided with a locking hole 122a, which is used to accommodate the bucket teeth 3232 extending into it. As a further example, the shape and size of the locking hole 122a are matched with the shape and size of the bucket teeth 3232, so that after the bucket teeth 3232 extend into the locking hole 122a, the outer wall of the bucket teeth 3232 is fitted against the inner wall of the locking hole 122a.

[0058] For example, please refer to Figure 7 and Figure 10 The lug has a through hole 325a for accommodating the fourth shaft 125.

[0059] In some embodiments, please refer to Figure 3 The elastic component 160 includes an elastic element 161, a first connector 163 and a second connector 165. One end of the elastic element 161 is fixedly or rotatably connected to the first shaft 121 through the first connector 163, and the other end of the elastic element 161 is fixedly or rotatably connected to the third shaft 143 through the second connector 165.

[0060] In some embodiments, please refer toFigure 3 The elastic element 161 is at least one of a spring and elastic rubber.

[0061] It is understood that the spring can be at least one of a metal spring and a rubber spring. The elastic rubber can be an elastic rubber cord made of elastic rubber.

[0062] This application also provides an excavation device 10. Please refer to... Figures 7 to 9 and combined Figure 1 The excavating device 10 includes a bucket 300 and a cleaning assembly 100. The cleaning assembly 100 can be the cleaning assembly 100 with the structure described in any of the above embodiments. The cleaning assembly 100 is mounted on the back 3214 of the bucket 300 via a frame 120.

[0063] This application also provides an excavator 20. Please refer to... Figure 11 The excavator 20 includes: a body 200, a robotic arm 400, a bucket 300, and a cleaning assembly 100. The cleaning assembly 100 can be the cleaning assembly 100 with the structure described in any of the above embodiments. The robotic arm 400 is connected to the body 200. The bucket 300 is connected to the robotic arm 400. The cleaning assembly 100 is mounted on the back 3214 of the bucket 300 via a frame 120.

[0064] This application also provides a construction method. Please refer to the embodiments below. Figure 16 and combined Figure 1 , Figure 7 and Figure 11 The construction method includes: Step 110, prepare excavator 20.

[0065] Step 120: Prepare the cleaning component 100. The cleaning component 100 can be the cleaning component 100 with the structure described in any of the above embodiments.

[0066] Step 130: The cleaning component 100 is installed on the back 3214 of the bucket 300 by mounting the frame 120 on the back 3214 of the bucket 300.

[0067] Step 140: By operating the bucket 300 of the excavator 20, the scraping component 140 is inserted into the recess 23 between the piles and the scraping component 140 is moved up and down to remove the soil 25 between the piles located in the recess 23 between the piles.

[0068] Understandably, this construction method can remove the soil 25 between piles. It can clean the soil 25 between piles without damaging the pile body 21.

[0069] For example, in step 120, the structure of the cleaning component 100 can be as follows: (See [link to relevant documentation]).Figure 2 The frame 120 includes a first shaft 121 and a second shaft 123 arranged along a first direction; The scraping component 140 includes a connecting body 141, a third shaft 143, and at least one scraper 145; one end of the connecting body 141 is rotatably connected to the second shaft 123, and the other end is connected to at least one scraper 145; the third shaft 143 is disposed along the first direction on the connecting body 141 and is located between the second shaft 123 and the at least one scraper 145.
