Description

Technical Field

[0001] The invention belongs to the technical field of dredging construction, and in particular relates to construction dredging processing equipment and method. Background Art

[0002] Dredging involves clearing, widening, or deepening rivers, lakes, and other waterways by excavating earth and rock underwater using human or mechanical means. The main purposes of dredging include: excavating harbor basins and access channels; creating land for the construction of docks, port areas, port-side industrial zones, coastal urban land, and recreational areas; maintaining beaches; preventing floods and desilting reservoirs; improving the aquatic environment and restoring the ecosystem of rivers, lakes, and oceans; and constructing and filling trenches for various underwater pipelines.

[0003] However, existing traditional dredging equipment has limitations in terms of tool configuration, such as the inability to flexibly replace tools: Previous dredging equipment generally uses a fixed tool design, where the widening tool and the dredging tool are fixedly installed on the equipment. When different operations need to be performed (such as switching from widening to dredging), the equipment cannot flexibly replace multiple sets of tools arranged around the circumference. Although some equipment has the function of tool replacement, it is often only possible to replace a single set of tools in sequence, and it is impossible to replace multiple sets of tools simultaneously. This brings many inconveniences to dredging operations:

[0004] 1. Low operational efficiency: Since multiple sets of cutters cannot be changed simultaneously, switching from widening to dredging, or vice versa, requires a significant amount of time to replace cutters sequentially. For example, in a large-scale dredging project, if the operation mode needs to be frequently switched, each cutter change process can waste at least several hours or even longer, causing a significant delay in the progress of the entire dredging project.

[0005] 2. Poor equipment adaptability: Dredging operations are complex and ever-changing, requiring different operating methods in different areas. The inability to flexibly change cutters makes it difficult for equipment to quickly adapt to different operational needs. For example, when encountering a narrow area that needs to be dredged, if spiral cutters cannot be replaced in time, the equipment will not work effectively and may even be damaged.

[0006] 3. Increased maintenance costs: Because tool replacement cannot be performed efficiently, the equipment will be forced to operate under inappropriate tool configuration, which will cause excessive wear and damage to the tool and increase the tool loss rate; at the same time, due to uneven tool wear, it will affect the overall performance of the equipment, further increasing the maintenance cost and difficulty of the equipment.

[0007] 4. Complicated operation: the operator needs to replace each group of cutters separately, which not only increases the labor intensity of the operator, but also is prone to operation errors. For example, during the sequential replacement of cutters, problems such as loose cutter installation or incorrect cutter position installation may occur, affecting the normal operation of the equipment.

[0008] Based on the above defects, the present application is proposed. SUMMARY

[0023] Wherein, the cross-sectional shape of the chute is T-shaped.

[0024] The present invention also provides a construction dredging method, comprising the following steps:

[0025] S1: Equipment pre-adjustment

[0026] According to the operation conditions of widening operation and dredging operation, adjust the corresponding tool to switch to the outside of the equipment:

[0027] Mode 1: During widening operation, multiple wide-blade cutters arranged circumferentially are synchronously adjusted to the outside through the conversion unit;

[0029] S2: Construction

[0031] S3: According to the two constructions of dredging expansion and dredging guidance, the opening and closing angles of the first and second side plates need to be adjusted

[0032] Scenario 1: During dredging and expanding, the first and second side plates of each set are adjusted to their maximum extension through the adjustment unit;

[0033] Scenario 2: During dredging guidance, the adjustment unit is used to adjust and retract each set of first side plates and second side plates to a minimum, so that each set of first side plates and second side plates fit closely together;

[0034] Among them, S1 and S3 can be used in combination as follows:

[0035] Method 1: S1 Mode 1 + S3 Scenario 1;

[0036] Method 2: S1 mode 1 + S3 scenario 2;

[0037] Method 3: S1 Mode 2 + S3 Scenario 1;

[0038] Method 4: S1 Mode 2 + S3 Scenario 2.

[0039] Compared with the prior art, the construction dredging equipment and method of the present invention have the following beneficial effects:

[0040] First, in view of the problem that traditional dredging equipment cannot realize flexible replacement of cutters or simultaneous replacement of multiple sets of cutters, which brings many inconveniences to dredging construction, the present invention can realize the synchronous rotation and position adjustment of multiple sets of wide-blade cutters and spiral cutters through the cooperation of the second bevel gear and multiple first bevel gears, and can flexibly realize the replacement of cutters. The simultaneous replacement of multiple sets of cutters saves time for tool replacement in different working environments and improves working efficiency. The equipment can adapt to complex environments in different situations, reduces unnecessary tool loss caused by the inability to replace cutters in time, reduces maintenance costs, and simplifies the operation of synchronously switching multiple sets of cutters, avoiding mistakes caused by cumbersome operating steps.

[0041] Second, the present invention can achieve synchronous rotation of all wide-blade cutters and spiral cutters through the rotation of the second bevel gear, and ensure that each group of wide-blade cutters and spiral cutters flips the same after rotation, thereby ensuring that each group of wide-blade cutters and spiral cutters rotates at the same angle, ensuring that when the equipment is subsequently working, each group of wide-blade cutters or spiral cutters can play the same role in the circumferential direction of the equipment, avoiding the problem that after a single position adjustment, the uneven position of each group of wide-blade cutters or spiral cutters causes the construction effect of a certain position in the circumference of the equipment to be adversely affected;

[0042] 3. The present invention promotes the intermittent rotation of the disc, the first teeth, and the fixed pin through the first motor, the third rotating shaft, the rotating disc, the second teeth, and the elastic paddle, thereby promoting the intermittent rotation of the second bevel gear, and can realize automatic locking and maintaining stability after the second bevel gear rotates. By means of the intermittent rotation characteristics of the second bevel gear, multiple groups of first bevel gears are driven to perform intermittent rotation operations synchronously, and the self-locking function of the second bevel gear after the intermittent rotation is utilized, so that the multiple groups of first bevel gears can also achieve self-locking after completing the intermittent rotation. Furthermore, through the coordinated cooperation between the disc, the first teeth and other related components, the rotation behavior of multiple groups of wide-blade tools and spiral tools and the self-locking state after rotation can be effectively controlled. The entire adjustment process is simple and easy, the positioning state after the adjustment is completed is stable and reliable, and the switching between the rotation mode and the positioning mode can be carried out smoothly.

[0043] Fourth, in the present invention, when the third rotating shaft, the rotating disk and the elastic paddle complete a 360-degree rotation, they will drive the disc, the first teeth, the fixing pin, the second rotating shaft and the second bevel gear to rotate 180 degrees, thereby driving multiple groups of first bevel gears to rotate 180 degrees synchronously, thereby achieving 180-degree rotation of each group of the first bevel gear, the first connecting seat, the wide-blade cutter and the spiral cutter; with the help of the intermittent rotation of the second bevel gear each time, the positions of the multiple groups of wide-blade cutters and spiral cutters can be adjusted, and after the adjustment is completed, the positions of the wide-blade cutters and spiral cutters can be ensured to face the outside of the equipment, so that the cutters are in the correct position, avoiding incomplete dredging caused by tool position deviation, improving the accuracy of the dredging effect, and thus providing a guarantee for the subsequent smooth dredging operation;

[0044] 5. The present invention provides an excavating head at the top of the top seat. When the equipment is in operation, the excavating head can first perform a rotary dredging operation on the construction location to form a prefabricated borehole, and then the wide-blade tool or spiral tool arranged circumferentially of the equipment can be used to further expand the prefabricated borehole. In this way, the jamming and adjustment time of the wide-blade tool and the spiral tool during operation are reduced, thereby improving the efficiency of drilling and expanding operations. Compared with directly using the wide-blade tool and the spiral tool for drilling operations, this operation method effectively reduces the wear of the wide-blade tool and the spiral tool. The step-by-step operation of the excavating head performing rotary dredging to form the prefabricated borehole and the wide-blade tool or the spiral tool performing the expanding operation makes the entire drilling and expanding process smoother and more efficient.

[0045] 6. The present invention can drive the rotating seat to rotate relative to the first chamber through the second motor, the second gear, the fourth rotating shaft, the first gear, and the rotating column, so that the components above the rotating seat can rotate synchronously with the rotating seat. That is, the excavating head and multiple groups of wide-blade cutters and spiral cutters arranged circumferentially can rotate synchronously through the same driving force. The same driving force ensures that the movement rhythm of the excavating head, wide-blade cutters, and spiral cutters is completely consistent during the rotation process. In the dredging operation, it promotes a smooth connection between the pre-drilling operation and the subsequent reaming operation, avoiding jamming or operation interruption caused by asynchronous rotation. It also simplifies the mechanical structure of the equipment, reduces the number of parts of the equipment, reduces the manufacturing cost and assembly difficulty of the equipment, and makes the control system more concise and efficient.

[0046] 7. Materials generated in existing dredging operations tend to accumulate in holes, affecting subsequent operations. To address this issue, the present invention provides a dredging guide channel consisting of multiple sets of first side plates, second side plates, and second chambers below the first chamber. The dredged and excavated materials are guided by the first and second side plates and discharged into the second chamber. In conjunction with the existing vibration motor, the materials can be smoothly discharged from the first and second side plates and the second chamber, avoiding operation stagnation caused by material accumulation in holes and ensuring the continuous operation of subsequent dredging projects.

[0047] 8. In the present invention, the opening and closing angles of each group of first side panels and second side panels can be flexibly adjusted. During the excavation stage, the first side panels and second side panels are extended to their maximum extent, so that the free ends of each group of first side panels and second side panels are in contact with the inner wall of the hole, thereby realizing further hole expansion construction work of the hole excavation and achieving the superimposed effect of dredging and hole expansion construction; when the first side panels and second side panels are retracted and extended to their minimum extent, the first side panels and second side panels form a dredging guide channel around the bottom of the first chamber, and at this time, the first side panels and second side panels are located on the relative inner sides of the bottom end of the wide-blade tool, that is, when the wide-blade tool or the spiral tool is expanding the hole, the second side panels and the first side panels in the retracted state will not contact the inner wall of the hole, thereby reducing dredging resistance and ensuring the normal guiding effect of materials in narrow environment operations;

[0048] 9. The present invention, through the arrangement of the cylinder, the lifting frame, and the support rod, can achieve synchronous opening and closing angle adjustment of multiple groups of first and second side panels arranged in the circumferential direction, ensuring the coordination and consistency of each group of first and second side panels after adjustment, thereby ensuring that each group of first and second side panels can play the same hole-expanding role in the circumference of the equipment in the extended state, and ensuring that the adjustment angles of two adjacent groups of first and second side panels in the retracted state are the same, thereby ensuring that the first and second side panels in the subsequent retracted state are tightly connected to form a tight dredging guide channel;

[0049] 10. The present invention provides multiple sets of first and second side panels that can be synchronously adjusted in opening and closing angles, thereby flexibly meeting the two construction requirements of dredging and expanding holes or guiding dredging materials. The same component performs multiple functions, and the operator does not need to perform complicated component replacement operations. The operator only needs to adjust the opening and closing angles of the first and second side panels to switch the construction function. This can meet the construction requirements of different construction scenes and construction stages without replacing equipment components. There is no need to configure multiple independent components for different functions, which saves installation space inside the equipment.

[0050] 11. The first and second side plates of the present invention have sharp ends in the extended state, which can achieve better deep digging with the inner wall of the hole during hole expansion, thereby enhancing the hole expansion effect;

[0051] 12. By setting the angle between the wide blade tool and the support column to 60 degrees to 90 degrees, it is ensured that the wide blade tool and the spiral tool can extend outward a sufficient distance in this range to ensure a sufficient hole expansion radius, so that the hole expansion effect meets the expected requirements;

[0052] In summary, the present invention can flexibly realize the simultaneous replacement of tools, save the time of tool replacement in different working environments, improve working efficiency, the equipment can adapt to the complex environment of different situations, reduce unnecessary tool loss caused by the failure to replace tools in time, reduce maintenance costs, and at the same time, the operation of synchronous switching of multiple sets of tools is simpler, avoiding mistakes caused by cumbersome operating steps, and the angles of each set of wide-blade tools and spiral tools after rotation are the same, ensuring that they play the same role in the circumference of the equipment. In addition, the positions of multiple sets of wide-blade tools and spiral tools can be adjusted, and after the adjustment is completed, it can be ensured that the positions of the wide-blade tools and spiral tools are facing the outside of the equipment, so that the tools are in the correct position, avoiding tool position The deviation causes incomplete dredging, which improves the accuracy of the dredging effect, thereby providing a guarantee for the smooth implementation of subsequent dredging operations. In addition, the excavator head and multiple sets of wide-blade cutters and spiral cutters arranged circumferentially are rotated synchronously through the same driving force to ensure that their movement rhythm is completely consistent, which promotes a smooth connection between prefabricated drilling and subsequent reaming operations. A dredging guide channel consisting of multiple sets of first side plates, second side plates and second chambers is also provided, which can flexibly meet the two construction needs of dredging reaming or material dredging guidance. The same component realizes multiple functions. The construction function can be switched by adjusting the opening and closing angles of the first side plate and the second side plate. The construction needs of different construction scenes and construction stages can be met without replacing equipment components. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] Reference will be made mainly Figures 1 to 9As shown, a construction dredging processing equipment includes a first chamber 1, a rotating seat 2 is provided at the top of the first chamber 1 through a bearing, and the rotating seat 2 can rotate relative to the first chamber 1, and a cylinder 3 is fixedly installed on the top of the rotating seat 2, and the cylinder 3 is configured as a hollow cylinder. The top of the cylinder 3 is connected with a top seat 4, and a conversion unit is provided in the inner cavity of the cylinder 3 and the top seat 4. A plurality of groups of tool assemblies are provided on the side wall of the top seat 4 for circumferential rotation. Specifically, six groups of tool assemblies are provided, and each group of tool assemblies includes a wide-blade tool 11 and a spiral tool 12. The synchronous transformation of the positions of the wide-blade tool 11 and the spiral tool 12 in each group of tool assemblies is realized by the conversion unit. During widening operation, the wide-blade tool 11 is adjusted to face the outside of the equipment, and during dredging operation, the spiral tool 12 is adjusted to face the outside of the equipment.

[0067] Main references Figure 1 、 Figure 3 and 4 As shown, the conversion unit includes a second rotating shaft 18 that is rotatably arranged in the middle of the inner cavity of the top seat 4 in the vertical direction, and a second bevel gear 19 is fixedly installed on the top of the second rotating shaft 18. The second bevel gear 19 is equidistantly arranged with a plurality of first bevel gears 9 along the circumferential direction. Specifically, there are six first bevel gears 9, and each first bevel gear 9 is respectively meshed with the second bevel gear 19. The center of each first bevel gear 9 passes through and is fixedly installed with a first rotating shaft 8, and the first rotating shaft 8 passes through the side wall of the top seat 4 to the outside. The top end of the first rotating shaft 8 is rotatably connected to the connecting block 7 through a bearing, that is, the first rotating shaft 8 can rotate relative to the connecting block 7, and the bottom end of the first rotating shaft 8 is fixedly connected to the first connecting seat 10. The rotation of the shaft 8 drives the first connecting seat 10 to rotate synchronously, and the first connecting seat 10 is connected to the top end of the wide-blade tool 11 and the spiral tool 12. The rotation of the first connecting seat 10 drives the wide-blade tool 11 and the spiral tool 12 to rotate synchronously, so as to realize the adjustment and conversion of the positions of the wide-blade tool 11 and the spiral tool 12; wherein, a plurality of mounting seats 6 are installed at equal intervals along the circumferential direction on the top end of the inner wall of the top seat 4. Specifically, there are six mounting seats 6, and the number of mounting seats 6 is the same as that of the connecting blocks 7. Each connecting block 7 is fixedly connected to the inner cavity of the mounting seat 6 at the corresponding position, and the rotation of the first rotating shaft 8 is supported by the connecting blocks 7 and the mounting seats 6, so as to ensure that the first rotating shaft 8 can rotate stably;

[0068] By rotating the second bevel gear 19, multiple groups of circumferentially arranged first bevel gears 9 are driven to rotate synchronously, thereby driving the first rotating shaft 8, first connecting seat 10, wide-blade tool 11, spiral tool 12 and second connecting seat 13 corresponding to each group of first bevel gears 9 to rotate synchronously, thereby realizing the adjustment of the positions of the wide-blade tool 11 and the spiral tool 12.

[0069] Main references Figure 4As shown, each group of wide-blade tools 11 and spiral tools 12 are respectively equipped with a second connecting seat 13 at the bottom end, and each second connecting seat 13 is rotatably connected to a connecting column 14 on the side facing away from the first connecting seat 10. A plurality of groups of support columns 15 are equidistantly arranged on the side wall of the rotating seat 2 along the circumferential direction, and each support column 15 corresponds to the position of each connecting column 14, and the support column 15 is fixedly connected to the connecting column 14. When the wide-blade tool 11 and the spiral tool 12 rotate, the second connecting seat 13 can be driven to rotate relative to the connecting column 14, and the connecting column 14 can be stabilized by the support column 15. Fixed support ensures that the second connecting seat 13 can remain stable when rotating relative to the connecting column 14; specifically, the angle range between the wide-blade tool 11 and the support column 15 is set to 60 degrees to 90 degrees. When the angle is 60 degrees, the wide-blade tool 11 and the spiral tool 12 extend outward the longest distance. When the angle is 90 degrees, the wide-blade tool 11 and the spiral tool 12 extend outward the shortest distance. Within this range, it can ensure that the wide-blade tool 11 and the spiral tool 12 extend outward at an angle of sufficient distance to ensure that there is a sufficient hole expansion radius, so that the hole expansion effect meets the expected requirements.

[0070] Main references Figures 3 to 6As shown, the inner cavity of the cylinder 3 is provided with a power mechanism for driving the second rotating shaft 18 to rotate; the power mechanism includes a motor frame 16 and a support arm 17 respectively fixedly mounted on the top of the rotating base 2, a first motor 23 is provided on the support arm 17, the output end of the first motor 23 is connected to the third rotating shaft 24, and the third rotating shaft 24 is rotatably connected to the side wall of the support arm 17 through a bearing, a turntable 25 is fixedly mounted on the third rotating shaft 24, a plurality of second teeth 26 are provided on the side wall of the turntable 25, and an elastic paddle 27 is vertically mounted on the inner wall of the turntable 25 , and the elastic paddle 27 corresponds to the second tooth 26 in the inside and outside positions, and the first motor 23 is turned on to drive the third shaft 24, the turntable 25, the second tooth 26, and the elastic paddle 27 to rotate clockwise; the second shaft 18 is vertically and rotatably arranged on the support arm 17 from top to bottom, and a disk 20 is installed at the bottom end of the second shaft 18. Six first teeth 21 are arranged on the side wall of the disk 20, and every three first teeth 21 are symmetrically arranged on the side wall of the disk 20, and every three first teeth 21 can be rotatably embedded in the second Inside the teeth 26, two fixing pins 22 are vertically installed at the bottom end of the disc 20, and each fixing pin 22 corresponds to the position of each group of first teeth 21; wherein, the circumferential rotation of the elastic paddle 27 can drive the fixing pin 22 to be forced to rotate. Specifically, the elastic paddle 27 corresponds to the end position of the second teeth 26 in the clockwise direction, thereby ensuring that after the rotating elastic paddle 27 drives the fixing pin 22 to rotate, the first teeth 21 immediately engages with the second teeth 26, so as to achieve the clockwise engagement of the first teeth 21 and the second teeth 26. By turning on the first motor 23, the third rotating shaft 24, the rotating disk 25, the second teeth 26, and the elastic paddle 27 are driven to rotate clockwise. When the elastic paddle 27 rotates to touch the fixed pin 22 on the left, the fixed pin 22 on the left is caused to rotate simultaneously with the elastic paddle 27. At this time, the three first teeth 21 adjacent to the fixed pin 22 on the left are engaged with the second teeth 26, so that the disk 20 and the first teeth 21 rotate counterclockwise synchronously, thereby driving the second rotating shaft 18 and the second bevel gear 19 to rotate counterclockwise at the same time.

[0071] When the third rotating shaft 24, the rotating disk 25 and the elastic paddle 27 complete a 360-degree rotation, the disc 20, the first tooth 21, the fixing pin 22, the second rotating shaft 18 and the second bevel gear 19 will be driven to rotate 180 degrees, thereby driving multiple groups of first bevel gears 9 to rotate 180 degrees synchronously, thereby realizing that each group of the first bevel gear 9, the first connecting seat 10, the wide-blade tool 11 and the spiral tool 12 rotates 180 degrees; with the help of the intermittent rotation of the second bevel gear 19 each time, the position of the multiple groups of wide-blade tools 11 and the spiral tool 12 can be adjusted, and after the adjustment is completed, it can be ensured that the position of the wide-blade tool 11 and the spiral tool 12 is facing the outside of the equipment, so that the tool is in the correct position, avoiding incomplete dredging caused by tool position deviation, improving the accuracy of the dredging effect, and providing a guarantee for the subsequent smooth dredging operation.

[0073] The turned-on second motor 32 drives the fourth rotating shaft 30 and the second gear 31 to rotate synchronously, thereby driving the first gear 29 and the rotating column 28 to rotate. The rotation of the rotating column 28 drives the rotating base 2 to rotate relative to the first chamber 1, so as to realize the synchronous circumferential rotation of the multiple sets of tools and the excavating head 5 arranged above the rotating base 2. The rotating excavating head 5 first performs a rotational dredging operation on the construction position to form a prefabricated borehole, and then the prefabricated borehole is further expanded by the rotation action of the circumferentially arranged wide-blade tool 11 or spiral tool 12. In this way, the jamming and adjustment time of the wide-blade tool 11 and the spiral tool 12 during the operation are reduced, and the efficiency of the drilling and expanding operations is improved. Compared with directly using the wide-blade tool 11 and the spiral tool 12 for drilling operations, this operation method effectively reduces the wear of the wide-blade tool 11 and the spiral tool 12, and the excavating head 5 performs rotational dredging to form a prefabricated borehole and the wide-blade tool 11 or the spiral tool 12 performs expansion processing in a step-by-step operation mode, making the entire drilling and expanding process smoother and more efficient.

A second chamber 35 is installed on the outer end of the fixing arm 34. The second chamber 35 is a hollow cylinder, and the vertical center axis of the second chamber 35 is collinear with the vertical center axis of the first chamber 1. Four groups of first side plates 36 are respectively provided on the top of the second chamber 35 through pin rotation. The side walls of each first side plate 36 are respectively installed with a second side plate 37, and the second side plate 37 is arranged in an inverted triangle.

The second side plates 37 and the first side plates 36 in the contracted state will not contact the inner wall of the hole, thereby reducing dredging resistance and ensuring the normal guiding function of materials in narrow environment operations.

[0075] Referring mainly to Figure 10 and Figure 11 As shown in the figure, each group of first side plates 36 and second side plates 37 is angle-adjusted by an adjusting unit, and when the second side plate 37 is tightly closed with the adjacent group of first side plates 36, the first side plate 36, the second side plate 37 and the second chamber 35 form a dredging guide channel, and when the second side plate 37 is separated from the adjacent group of first side plates 36, the second side plate 37 and the first side plate 36 extend outward to assist in dredging reaming; the adjusting unit comprises a fixed seat 38 fixedly installed on the side wall of each first side plate 36, a sliding groove 39 is formed in the side wall of the fixed seat 38, a sliding block 40 is slidably embedded in the sliding groove 39, one end of a support rod 41 is rotatably connected to the sliding block 40, a lifting frame 42 is slidably sleeved on the second chamber 35, and the other end of the support rod 41 is rotatably connected to the lifting frame 42, a pneumatic cylinder 43 is installed on the second chamber 35, and the output end of the pneumatic cylinder 43 is connected to the lifting frame 42; before the first side plate 36 and the second side plate 37 are used for dredging reaming, the lifting frame 42 is moved by the opened pneumatic cylinder 43, and as the lifting frame 42 moves, the bottom end of the circumferentially arranged plurality of support rods 41 is synchronously moved, and then the sliding block 40 rotatably connected to the top end of the support rod 41 is moved along the inner cavity of the sliding groove 39, so as to realize the synchronous outward opening and extension of each group of first side plates 36 and second side plates 37 connected with each group of fixed seats 38, so as to adjust the opening and extension angle of the first side plate 36 and the second side plate 37 to the maximum, and at this time, the sharp end of the first side plate 36 and the second side plate 37 faces outward, which can realize better deepening with the inner wall of the hole during reaming and enhance the reaming effect. The cross-sectional shape of the sliding groove 39 is T-shaped, and the T-shaped sliding groove 39 can ensure that the sliding block 40 slides along the sliding groove 39 without leaving the inner cavity of the sliding groove 39.

[0076] The present application also provides a construction dredging treatment method, comprising the following steps:

[0077] S1: equipment pre-adjustment

[0078] According to the operation conditions of the two modes of widening operation and dredging operation, the corresponding cutters are adjusted to the outside of the equipment:

[0079] Mode one: when widening operation, a plurality of wide blade cutters 11 arranged circumferentially are synchronously adjusted to the outside by a conversion unit;

[0080] Mode two: when dredging operation, a plurality of spiral cutters 12 arranged circumferentially are synchronously adjusted to the outside by a conversion unit;

[0081] By turning on the first motor 23, the third rotating shaft 24, the rotating disk 25, the second teeth 26, and the elastic paddle 27 are driven to rotate clockwise. When the elastic paddle 27 rotates to touch the fixed pin 22 on the left, the fixed pin 22 on the left will be prompted to rotate simultaneously with the elastic paddle 27. At this time, the three first teeth 21 adjacent to the fixed pin 22 on the left rotate and engage with the second teeth 26, so that the disk 20 and the first teeth 21 rotate synchronously counterclockwise, thereby driving the second rotating shaft 18 and the second bevel gear 19 to rotate counterclockwise at the same time; through the rotation of the second bevel gear 19, the multiple groups of first bevel gears 9 arranged circumferentially are driven to rotate synchronously, thereby driving the first rotating shaft 8, the first connecting seat 10, the wide-blade tool 11, the spiral tool 12 and the second connecting seat 13 corresponding to each group of first bevel gears 9 to rotate synchronously, thereby adjusting the positions of the wide-blade tool 11 and the spiral tool 12, and adjusting the appropriate tool to face the outside of the equipment for subsequent use.

[0082] S2: Construction

[0083] The excavating head 5 and the multiple sets of wide-blade cutters 11 and spiral cutters 12 arranged circumferentially are rotated synchronously by the same driving force, thereby achieving the combined effect of pre-drilling and subsequent hole enlarging operations;

[0084] The turned-on second motor 32 drives the fourth rotating shaft 30 and the second gear 31 to rotate synchronously, thereby driving the first gear 29 and the rotating column 28 to rotate. The rotation of the rotating column 28 drives the rotating base 2 to rotate relative to the first chamber 1, so as to realize the synchronous circumferential rotation of the multiple sets of tools and the excavating head 5 arranged above the rotating base 2. The rotating excavating head 5 first performs a rotational dredging operation on the construction position to form a prefabricated borehole, and then the prefabricated borehole is further expanded by the rotation of the circumferentially arranged wide-blade tool 11 or spiral tool 12.

[0085] S3: According to the two constructions of dredging and reaming and dredging guidance, the opening and closing angles of the first side plate 36 and the second side plate 37 need to be adjusted

[0086] Scenario 1: During dredging and expanding, each set of first side plates 36 and second side plates 37 are adjusted to their maximum extension through the adjustment unit;

[0087] Scenario 2: During dredging and guiding, each set of first side plates 36 and second side plates 37 are adjusted and retracted to a minimum through the adjustment unit, so that each set of first side plates 36 and second side plates 37 are closely fitted together;

[0088] Among them, S1 and S3 can be used in combination as follows:

[0089] Mode 1: S1 Mode 1 + S3 Scenario 1. In this mode, the widening operation is performed by the wide-blade cutter 11, and the dredging and expanding operation is achieved in conjunction with the first side plate 36 and the second side plate 37;

[0090] Mode 2: S1 Mode 1 + S3 Scenario 2. In this mode, the wide-blade cutter 11 is used for widening operations, and the dredging guide channel formed by the first side plate 36, the second side plate 37 and the second chamber 35 is used to guide the material discharge;

[0091] Mode 3: S1 Mode 2 + S3 Scenario 1. In this mode, the spiral cutter 12 is used for dredging operations, and the first side plate 36 and the second side plate 37 are used to achieve dredging and hole expansion operations.

[0092] Mode 4: S1 Mode 2 + S3 Scenario 2. In this mode, the spiral cutter 12 is used for dredging operations, and the dredging guide channel formed by the first side plate 36, the second side plate 37 and the second chamber 35 is used to guide the material discharge.

[0093] A plurality of vibration motors are provided on the side wall of the second chamber 35. The vibration motors are of commonly used models on the market, which can vibrate the materials in the second chamber 35 to assist in unloading. The assembly and model of the vibration motors are not excessively described or limited here. The bottom of the second chamber 35 is connected to an existing driving device for dredging construction. The driving device can realize the function of rotating the second chamber 35 and the equipment as a whole. The driving device is not excessively described or limited here. Through the existing driving device, the second chamber 35 is caused to rotate, so as to realize the circumferential rotation of the first side plate 36, the second side plate 37 and the equipment as a whole, and ensure that when the first side plate 36 and the second side plate 37 are extended to the maximum limit, they can rotate to perform rotary excavation of the hole. Cooperating with the self-rotating excavating head 5 and the wide-blade tool 11 or the spiral tool 12, the multiple excavation superposition effect of the equipment is achieved; the elastic pick 27 adopts a material with elasticity itself, for example, the elastic pick 27 is spring steel with a carbon content between 0.5% and 0.8%, and has a high elastic limit, strength limit and fatigue limit. The elastic pick 27 can also be set to brass. The elastic pick 27 has a certain elastic property to ensure that the elastic pick 27 has sufficient strength to rotate the fixed pin 22 and is forced to bend under the blocking action of the fixed pin 22. Then, the turntable 25 drives the elastic pick 27 to continue to rotate, prompting the elastic pick 27 to break away from the obstruction of the fixed pin 22 and automatically restore to a vertical state, preparing for the next cycle of tossing the fixed pin 22.

[0094] It is worth mentioning that the air cylinder 43 used in the present application is a commonly used self-locking air cylinder on the market, the output end of which can stop at any position and be locked; the first motor 23 and the second motor 32 are commonly used self-locking motors on the market, the output end of which can be locked, and the output end can be self-locked when the motor is stopped, and will not rotate under external force; the first motor 23 and the second motor 32 are commonly used positive and negative motors on the market, the output end of which can rotate forward or backward according to the use requirement, which can meet the above use requirement; the above existing components are not described in detail here.

[0095] The working principle of the construction dredging treatment equipment and method of the present embodiment is as follows:

[0096] First, adjust the equipment cutter to the appropriate position according to the construction environment: turn the third shaft 24, the rotating disc 25, the second gear teeth 26 and the elastic tab 27 clockwise by starting the first motor 23, when the elastic tab 27 rotates to touch the left fixed pin 22, it will make the left fixed pin 22 rotate at the same time with the elastic tab 27, at this time, the three first gear teeth 21 adjacent to the left fixed pin 22 are in meshing rotation with the second gear teeth 26, realizing the synchronous counterclockwise rotation of the disc 20 and the first gear teeth 21, to drive the second shaft 18 and the second bevel gear 19 to rotate counterclockwise at the same time; through the rotation of the second bevel gear 19, drive the multiple groups of first bevel gears 9 arranged in the circumferential direction to rotate synchronously, to drive the first shaft 8, the first connecting seat 10, the wide blade cutter 11, the spiral cutter 12 and the second connecting seat 13 corresponding to each group of first bevel gears 9 to rotate synchronously, realizing the adjustment of the positions of the wide blade cutter 11 and the spiral cutter 12, and adjusting the appropriate cutter to the outside of the equipment for subsequent use;

[0097] When the equipment is used for construction, the fourth shaft 30 and the second gear 31 are driven to rotate synchronously by starting the second motor 32, and then the first gear 29 and the rotating column 28 are driven to rotate, the rotating seat 2 is driven to rotate relative to the first chamber 1 by the rotation of the rotating column 28, to realize the synchronous circumferential rotation of the multiple groups of cutters arranged above the rotating seat 2 and the excavating head 5, the rotating excavating head 5 first performs rotary dredging operation on the construction position, to form a prefabricated drill hole, and then the rotary action of the circumferentially arranged wide blade cutter 11 or spiral cutter 12 further expands the hole;

[0098] When the material is dredged and guided, the adjacent first side plate 36 and the second side plate 37 are in close connection, the dredging guide channel composed of the circumferentially arranged multiple groups of first side plates 36, second side plates 37 and the second chamber 35, the dredged material enters the second chamber 35 under the guidance of the first side plate 36 and the second side plate 37 and is discharged, and the contracted second side plate 37 and the first side plate 36 do not contact the inner wall of the hole, reducing the dredging resistance and ensuring the normal guiding effect of the material in the narrow environment.

[0099] Before dredging and expanding the hole with the help of the first side plate 36 and the second side plate 37, the lifting frame 42 is driven to move by the opened cylinder 43. As the lifting frame 42 moves, the bottom ends of the plurality of circumferentially arranged support rods 41 are driven to move synchronously, thereby prompting the sliders 40 connected to the top ends of the support rods 41 to move along the inner cavity of the slide groove 39, so that each group of first side plates 36 and second side plates 37 connected to each group of fixing seats 38 can be synchronously opened and extended outward, so as to adjust the extension angle of the first side plates 36 and the second side plates 37 to the maximum limit. At this time, the sharp ends of the first side plates 36 and the second side plates 37 face outward, which can achieve better deep digging with the inner wall of the hole during expansion, thereby enhancing the expansion effect;

[0100] The present invention can flexibly realize the simultaneous replacement of tools, save the time of tool replacement in different working environments, improve working efficiency, and the equipment can adapt to complex environments in different situations, reduce unnecessary tool wear caused by the failure to replace tools in time, reduce maintenance costs, and realize the operation of synchronous switching of multiple sets of tools more simply, avoiding mistakes caused by cumbersome operating steps, and the angles of each set of wide-blade tools 11 and spiral tools 12 after rotation are the same, ensuring that they play the same role in the circumference of the equipment. In addition, the positions of multiple sets of wide-blade tools 11 and spiral tools 12 can be adjusted, and after the adjustment is completed, it can be ensured that the positions of the wide-blade tools 11 and spiral tools 12 are facing the outside of the equipment, so that the tools are in the correct position, avoiding tool position deviation and other causes. Incomplete dredging is caused, and the accuracy of dredging effect is improved, thereby providing a guarantee for the smooth implementation of subsequent dredging operations. In addition, the excavator head 5 and multiple sets of wide-blade tools 11 and spiral tools 12 arranged in the circumferential direction are synchronously rotated by the same driving force to ensure that their movement rhythm is completely consistent, thereby promoting a smooth connection between prefabricated drilling and subsequent reaming operations. A dredging guide channel consisting of multiple sets of first side plates 36, second side plates 37 and second chambers 35 is also provided, which can flexibly meet the two construction needs of dredging reaming or material dredging guidance. The same component realizes multiple functions. The construction function can be switched by adjusting the opening and closing angles of the first side plate 36 and the second side plate 37. The construction needs of different construction scenes and construction stages can be met without replacing equipment components.

[0101] Through this device, the following effects can be achieved:

[0102] 1. Improve work efficiency:

[0103] Rapidly switch between operating modes: Multiple tool sets can be changed simultaneously, allowing for rapid tool changes from widening to dredging and vice versa. For example, in large-scale dredging projects, where frequent mode changes are required, tool changes can be completed in just a few minutes or less, significantly accelerating project progress and eliminating time wasted on tool changes, resulting in a multifold increase in overall operational efficiency.

[0104] 2. Enhance equipment adaptability:

[0105] Adaptable to various operating environments: The cutters can be flexibly replaced, allowing the equipment to quickly adjust the cutter configuration according to the operational needs of different areas. For example, when encountering a narrow area that needs to be dredged, the spiral cutter can be promptly replaced, allowing the equipment to operate effectively in various complex environments, ensuring that the equipment can perform at its best under different working conditions and improving its adaptability to complex and changing dredging environments.

[0106] 3. Reduce maintenance costs:

[0107] Optimize tool usage and equipment performance: Efficient tool replacement ensures the equipment operates with the appropriate tool configuration, preventing excessive tool wear and damage and reducing tool loss. Furthermore, even tool wear helps maintain overall stable equipment performance. This reduces the frequency and difficulty of equipment maintenance and repair, lowers maintenance costs, and extends equipment life.

[0108] 4. Simplify the operation process:

[0109] Reduced operational difficulty and error rate: Operators no longer need to perform the tedious task of replacing each set of tools individually; instead, they only need to perform a single, integrated tool change. This not only reduces operator workload but also significantly reduces the likelihood of operational errors. For example, problems such as loose or incorrectly installed tools are avoided, ensuring normal equipment operation and improving reliability and stability.

[0110] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
