Description

Technical Field

[0001] The invention belongs to the technical field of roadbed maintenance and tree root removal and cleaning, and in particular relates to a road surface damaged by tree roots in a city. Background Art

[0002] With the development of society, people pay more and more attention to environmental protection issues. The green area in cities is gradually increasing. In order to purify the air and improve the quality of urban air, the planting of trees on both sides of the road has also increased. Appropriate roadbed trees can protect the road surface, prevent ice and snow erosion, and also beautify the environment. However, after a long period of growth, the growth of tree roots in the roadbed will damage the road surface. The roots will extend under the roadbed during the growth process. Most of the roots extend longitudinally or diagonally downward, and a small number of roots will extend horizontally, resulting in cracks, potholes, bulges, and subsidence on the road surface. Roadside trees grow slowly, and the damage is also a gradually intensified process. If not handled in time, it will seriously affect the traffic safety of the road. Therefore, the tree roots that damage the road surface on the roadbed and the tree roots that are about to damage the road surface should be removed and prevented from damage to ensure the safety and stability of the road.

[0003] Since manual removal of tree roots from the roadbed requires manual digging, the diameter of the holes opened is large, the workload is large, it is time-consuming and inefficient, which will affect urban traffic. Moreover, after a period of time after the tree roots from the roadbed are removed, the tree roots will still grow out and damage the road surface, causing cracks, potholes, bulges, subsidence, etc.

[0004] To this end, the present invention is to design a machine that can remove tree roots on the roadbed that have already damaged the road surface and prevent tree roots that are about to damage the road surface, so that work such as road construction is more convenient and efficient, thereby solving the cumbersome and dangerous nature of removing tree roots from the roadbed, improving work efficiency, reducing manual labor, and filling holes with concrete after clearing the tree roots to prevent the tree roots from damaging the road surface again. Therefore, the present invention is a machine that can effectively remove tree roots from the roadbed, can improve the quality and efficiency of road construction, and reduce construction costs and maintenance costs. At the same time, this machine can also be used for the maintenance of urban parks and green spaces to ensure the safety and comfort of citizens' travel and leisure. The research and development and application of removing tree roots from the roadbed and preventing tree roots from damaging the road surface are of great significance and value to urban greening and road landscaping, and have greatly improved the number of knowledge-based talents and improved the passive situation of relying on manpower construction in the past, which is of great significance.

[0005] Therefore, the above-mentioned technical defects in the prior art are technical problems that need to be solved urgently by technicians in this field. Summary of the invention

[0006] The purpose of the present invention is to provide a method and device for cleaning and filling underground spreading tree roots for roadbed maintenance, so as to solve the problem that tree roots in existing roadbeds damage the road surface, affecting traffic and people's safety.

[0007] The present invention is achieved in this way.

[0008] A method and device for cleaning and filling underground spreading tree roots for roadbed maintenance, including a fuselage structure, a drilling mechanism, a mixing mechanism, a turbine screw mechanism, a diesel generator and a driving universal wheel. The fuselage structure is designed to be divided into an upper and lower frame, which is convenient for realizing the lifting and lowering of the spiral drill. When the design is used, the overall lifting is adopted, and the upper and lower frames have a connecting rod that can be rotatably opened, so that the tree trunk can enter the center of the machine and the tree roots 50 cm deep around the tree trunk are cut off. The drilling mechanism is driven by a high-speed motor to drive the spiral drill, and holes are drilled successively around the tree to form a circular deep groove, which can realize the cutting of tree roots and trenching. The drilling accuracy is high, and the hole wall is neat and smooth, and the surrounding strata are not damaged. When the spiral drill cuts the tree roots, there is no need to excavate, which avoids ground disturbance and water pollution, and is beneficial to environmental protection. The mixing mechanism can realize the filling of the holes drilled by the spiral drill, and pour the mixed concrete into the deep annular groove to prevent the tree roots from damaging the road surface again in the later period. The turbine screw mechanism converts the high-speed turbine rotation into the axial movement of the screw, which can achieve the lifting stability of the lifting platform, and the lifting height and speed are large. The driving universal wheel can achieve omnidirectional movement, has better controllability and navigation, can achieve higher-precision positioning and motion control, and can quickly and flexibly cope with complex working environments.

[0009] Preferably, the fuselage mechanism includes an upper frame and a lower frame, wherein the first-stage reducer, the spiral drill rod driving motor, and the L-shaped bearing seat assembly are mounted on the upper frame by screws, and the transmission shaft is fixed to the upper frame by the L-shaped bearing seat assembly; wherein the turbine screw mechanism, the lifting mechanism driving motor, the stirring mechanism, and the diesel generator are mounted on the lower frame by screws, and the stirring barrel is fixed to the lower frame by the stirring barrel frame, so that the installation space positions of each device can be compactly distributed without affecting each other.

[0010] Preferably, the drilling mechanism mainly includes an auger rod driving motor, an auger rod, a primary reducer, a coupling, a transmission shaft, a thrust bearing, and a thrust bearing. The auger rod has an interference fit with a thrust bearing with an outer diameter of 58 mm. A thrust bearing with an outer diameter of 60 mm is used on the thrust bearing. The top of the auger rod uses a gasket with an outer diameter larger than the aperture of the bevel gear and a hexagon socket screw, so that the auger rod will not fall off when it is lowered and raised. The auger rod is driven by the auger rod motor to cut the tree roots and dig trenches. The auger rod driving motor is connected to the primary reducer through a coupling. After being decelerated by the primary reducer, the power is transmitted to the transmission shaft through a pulley. The transmission shaft drives the bevel gear to rotate through the pulley and cooperates with the lifting mechanism to make the auger rod rotate at high speed and move downward, and drill holes around the tree in sequence, forming a circular annular deep trench, thereby cutting the tree roots and digging trenches.

[0011] Preferably, the mixing mechanism mainly includes a mixer driving motor, a large bevel gear, a small bevel gear, a concrete delivery pipe, a concrete delivery pipe fixing sleeve, a control handle, a mixing barrel frame, and a mixing barrel. The driving method is that the mixer driving motor drives the small bevel gear to rotate through a belt transmission, and the rotation of the small bevel gear drives the large bevel gear to move, so that the mixing barrel can rotate to mix the concrete, and then the concrete is used to fill the annular deep groove caused by the tree roots through the concrete delivery pipe, so as to effectively prevent the tree roots from damaging the road surface again.

[0012] Preferably, the lifting mechanism mainly includes a lifting mechanism driving motor, a lifting coupling, a turbine screw, and a high-temperature Y-bearing seat assembly. The lifting coupling is fixed to the lower frame through the high-temperature Y-bearing seat assembly, and the lifting mechanism driving motor transmits kinetic energy through the pulley to drive the turbine screw mechanism to convert the high-speed turbine rotation into the axial movement of the screw. When the turbine rotates at high speed, a certain thrust is applied in the axial direction of the screw through the direct contact between the turbine and the screw, so that the screw produces axial movement, and the lifting function can be realized.

[0013] Preferably, the diesel generator converts internal energy into electrical energy to provide electrical energy for the electric motor.

[0014] Preferably, the driving universal wheel mainly includes a servo motor, a small cylindrical spur gear, a large cylindrical spur gear, a coaxial small cylindrical spur gear, a cylindrical spur gear, a small bevel gear, a large bevel gear, a small pulley, and a large pulley. The transmission process of the universal wheel is small cylindrical spur gear → large cylindrical spur gear → coaxial small cylindrical spur gear → cylindrical spur gear → small bevel gear → large bevel gear (connected to the wheel rotation shaft), and the transmission process of controlling the direction is small cylindrical spur gear → large cylindrical spur gear → small pulley → large pulley. The servo motor can realize omnidirectional movement, higher precision positioning and motion control. Since the overall weight of the underground spreading tree root cleaning and filling method and device for roadbed maintenance is relatively heavy, the gears and pulleys are made of 45 steel (quenched and tempered).

[0023] In order to make the present invention, technical solutions and advantages more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] like Figure 1The method and device for cleaning and filling underground spreading tree roots for roadbed maintenance shown in the figure include a fuselage structure, a drilling mechanism, a mixing mechanism, a turbine screw mechanism, a diesel generator and a driving universal wheel. The fuselage structure is designed to be divided into an upper and lower frame, which is convenient for realizing the lifting and lowering of the spiral drill. When the design is used, the overall lifting is adopted, and the upper and lower frames have a connecting rod that can be rotatably opened, so that the tree trunk can enter the center of the machine and the tree roots 50 cm deep around the tree trunk can be cut off. The drilling mechanism is driven by a high-speed motor to drive the spiral drill, and holes are drilled around the tree in sequence to form a circular deep groove, which can realize the cutting of tree roots and trenching. The drilling accuracy is high, and the hole wall is neat and smooth, and the surrounding strata are not damaged. When the spiral drill cuts the tree roots, there is no need to excavate, which avoids ground disturbance and water pollution, and is beneficial to environmental protection. The mixing mechanism can realize the filling of the holes drilled by the spiral drill, and pour the mixed concrete into the deep annular groove to prevent the tree roots from damaging the road surface again in the later period. The turbine screw mechanism converts the high-speed turbine rotation into the axial movement of the screw, which can achieve the lifting stability of the lifting platform, and the lifting height and speed are large. The driving universal wheel can achieve omnidirectional movement, has better controllability and navigation, can achieve higher-precision positioning and motion control, and can quickly and flexibly cope with complex working environments.

[0025] Specifically, Figure 1 As shown, the fuselage mechanism includes an upper frame 2 and a lower frame 4, wherein a primary reducer 5, a spiral drill rod driving motor 7, and an L-shaped bearing seat assembly 1 are mounted on the upper frame 2 by screws, and a transmission shaft 3 is fixed to the upper frame 2 by the L-shaped bearing seat assembly 1; wherein a turbine screw mechanism 13, a lifting mechanism driving motor 12, a stirring mechanism 8, and a diesel generator 11 are mounted on the lower frame 4 by screws, and a stirring barrel 19 is fixed to the lower frame 4 by a stirring barrel frame 21, so that compact distribution can be achieved and the installation space positions of each device do not affect each other.

[0026] Specifically, Figure 1As shown, the drilling mechanism mainly includes an auger rod driving motor 7, an auger rod 14, a primary reducer 5, a coupling 6, a transmission shaft 3, a thrust bearing 16, and a thrust bearing 15. The auger rod is interference-fitted with a thrust bearing 16 with an outer diameter of 58 mm. A thrust bearing 15 with an outer diameter of 60 mm is used on the thrust bearing 16. The uppermost part of the auger rod 14 uses a gasket with an outer diameter larger than the aperture of the bevel gear and a hexagon socket screw, so that the auger rod 14 will not fall off when it is lowered and raised. The auger rod 14 cuts the tree roots and digs the trench through the auger rod motor drive 7. The auger rod driving motor 7 is connected to the primary reducer 5 through the coupling 6. After being decelerated by the primary reducer 5, the power is transmitted to the transmission shaft 3 through the pulley. The transmission shaft 3 drives the bevel gear to rotate through the pulley and cooperates with the lifting mechanism to make the auger rod 14 rotate at high speed and move downward, and drill holes around the tree in sequence, forming a circular annular deep trench, so as to cut the tree roots and dig trenches.

[0027] Specifically, Figure 3 As shown, the mixing mechanism mainly includes a mixer driving motor 17, a large bevel gear 20, a small bevel gear 18, a concrete delivery pipe 10, a concrete delivery pipe fixing sleeve 9, a control handle 21, a mixing barrel frame 22, and a mixing barrel 19. The driving mode is that the mixer driving motor 17 drives the small bevel gear 18 to rotate through a belt drive, and the rotation of the small bevel gear 18 drives the large bevel gear 20 to move, so that the mixing barrel 19 can rotate to mix the concrete, and then the concrete is used to fill the annular deep groove caused by the tree roots through the concrete delivery pipe 10, so as to effectively prevent the tree roots from damaging the road surface again.

[0028] Specifically, Figure 4 As shown, the lifting mechanism mainly includes a lifting mechanism driving motor 12, a lifting coupling 24, a worm screw 25, and a high-temperature Y-bearing seat assembly 23. The lifting coupling 24 is fixed to the lower frame 4 through the high-temperature Y-bearing seat assembly 23. The lifting mechanism driving motor 12 transmits kinetic energy through the pulley to drive the worm screw mechanism 13 to convert the rotation of the high-speed turbine 26 into the axial movement of the screw 25. When the turbine 26 rotates at a high speed, a certain thrust is applied in the axial direction of the screw 25 through the direct contact between the turbine 26 and the screw 25, so that the screw 25 produces axial movement, and the lifting function can be realized.

[0029] Specifically, Figure 6 As shown, the diesel generator 11 converts internal energy into electrical energy to provide electrical energy for the electric motor.

[0030] Specifically, Figure 7As shown, the driving universal wheel mainly includes a servo motor 27, a small cylindrical spur gear 28, a large cylindrical spur gear 29, a coaxial small cylindrical spur gear 35, a cylindrical spur gear 34, a small bevel gear 32, a large bevel gear 33, a small pulley 30, and a large pulley 31. The transmission process of the universal wheel rotation is small cylindrical spur gear 28 → large cylindrical spur gear 29 → coaxial small cylindrical spur gear 35 → cylindrical spur gear 34 → small bevel gear 32 → large bevel gear 33 (connected to the wheel rotation shaft), and the transmission process of controlling the direction is small cylindrical spur gear 28 → large cylindrical spur gear 29 → small pulley 30 → large pulley 31. Driven by the servo motor 27, omnidirectional movement, higher precision positioning and motion control can be achieved. Since the overall weight of this underground spreading tree root cleaning and filling method and device for roadbed maintenance is relatively heavy, the gears and pulleys are both made of 45 steel (quenched and tempered).

[0031] It should be noted that the device provided by this patent can meet the needs of road construction, urban construction, etc. with slight modifications, but they all fall within the scope of protection of this patent.

When working, the connecting rods of the upper frame 2 and the lower frame 4 are opened to allow the tree trunk to enter the center of the machine, the connecting rods are locked, the diesel engine 11 is started, the auger rod driving motor 7 is connected to the primary reducer 5 through the coupling 6, and after being decelerated by the primary reducer 5, the power is transmitted to the transmission shaft 3 through the pulley, the transmission shaft 3 drives the bevel gear to rotate through the pulley, and the bevel gear drives the auger rod 14 to rotate, and at the same time, the lifting mechanism driving motor 12 transmits kinetic energy through the pulley, driving the turbine screw mechanism 13 to convert the rotation of the high-speed turbine 26 into the axial movement of the screw 25. When the turbine 26 rotates at high speed, a certain thrust is applied in the axial direction of the screw 25 through the direct contact between the turbine 26 and the screw 25, so that the screw 25 produces axial movement, and the auger rod 14 cooperates with the turbine screw mechanism 13 to rotate at high speed and move downward. After the drilling is completed, the auger rod 14 rises again through the turbine screw mechanism 13, moves the universal wheel, and drills holes around the tree in turn, forming a circular annular deep groove, thereby cutting off the tree roots and digging the groove.

[0034] Afterwards, the mixer driving motor 17 drives the small bevel gear 18 to rotate through the belt transmission, and the rotation of the small bevel gear 18 drives the large bevel gear 20 to move, so that the mixing barrel 19 can rotate to mix the concrete, and then the concrete conveying pipe 10 is used to fill the deep annular groove caused by the tree roots with concrete, so as to effectively prevent the tree roots from damaging the road surface again.

[0035] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative labor are still within the scope of protection of the present invention.
