Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of soft soil solidification, and specifically relates to a soft soil solidification device. BACKGROUND

[0002] The soft soil solidification technology is a technology for changing the properties of soft soil through physical and chemical means. The core is to mix the special solidifying agent (such as cement, lime, fly ash, and high polymer material) with the soft soil, and to uniformly distribute the solidifying agent in the soft soil through the stirring equipment and to initiate a series of physical and chemical reactions. These reactions can reduce the water content of the soft soil and enhance its cementation strength, and finally form a composite stable base layer with certain bearing capacity.

[0003] The existing soft soil solidification technology uses physical drainage and heating solidification, and uses the addition of chemical substances to make the soft soil coagulate and solidify. Among them, the more commonly used method is to add a composite chemical substance into the soft soil to improve the properties of the soil body and improve its strength and stability. Specifically, a stirring head installed on the mechanical arm of an excavator is used to add a soft soil solidifying agent mixed by water to the soft soil under the condition of sufficient stirring of the “Y”-shaped stirring head, so that the soft soil and the soft soil solidifying agent at different depths are repeatedly stirred and mixed to solidify the soft soil.

[0004] However, although the existing stirring head can fully stir the soil in the horizontal and vertical directions, and can be deep into the soil for soft soil solidification by means of the mobility of the mechanical arm of the excavator, due to the small area of the stirring head and the use of the radial spiral stirring method, when solidifying the large-area shallow soft soil, only repeated and tedious stirring operation can be performed, and the efficiency is not as expected.

[0005] Therefore, it is necessary to provide a soft soil solidification device which can efficiently solidify the shallow soft soil and repeatedly mix the soft soil solidifying agent and the soft soil, so as to ensure the efficiency of the large-area shallow soft soil solidification operation while retaining the deep soft soil solidification operation capability. SUMMARY

[0006] In order to solve the above problems, the purpose of the present application is to provide a soft soil solidification device which can mix and solidify the shallow soft soil on a straight line by flattening the chain while stirring and mixing, and can uniformly mix the input soft soil solidifying agent with the soft soil, so as to make the shallow soft soil solidification operation more efficient and reduce unnecessary solidification cost.

[0007] In order to achieve the above object, the technical scheme of the present application is as follows: A soft soil solidification device, comprising a excavator body and a controller arranged in the body, a support arm detachably and rotatably connected to the end of the mechanical arm of the excavator body, a steering assembly arranged in the support arm, a rotating groove opened at the end of the support arm away from the mechanical arm, a rotating motor fixedly connected to the wall of the rotating groove, a rotating wheel coaxially fixedly connected to the output shaft of the rotating motor, a frame fixedly connected to the outer periphery of the rotating wheel, an earth digging assembly and a gyroscope arranged on the frame, and a conveying assembly arranged on the inner side of the frame, wherein the gyroscope and the conveying assembly are signal connected to the controller, and the steering assembly is used to realize the radial rotation of the support arm; the earth digging assembly is used to dig and mix the shallow soft soil; and the conveying assembly is used to convey the soft soil solidification agent in several directions inside the frame.

[0008] The principle of the basic scheme is that after the device is started, the excavator body provides power, the mechanical arm sends the support arm and the earth digging assembly to the working position. The steering assembly adjusts the radial rotation angle of the support arm, so that the earth digging assembly is aligned with the area of the shallow soft soil to be solidified. The rotating motor is started to drive the rotating wheel and the frame to rotate, and the earth digging assembly starts to dig and mix the soft soil. At the same time, the conveying assembly starts to uniformly spray or inject the soft soil solidification agent into the mixed soft soil. Through the continuous stirring of the earth digging assembly, the soft soil and the solidification agent are fully mixed to form a uniform solidified soil body. When the earth digging assembly is working, the excavator body can slowly move, so that the soft soil is mixed and mixed through the inside of the frame, thereby improving the operation efficiency of the soft soil solidification.

[0009] The beneficial effects of the basic scheme are: 1. The chain transmission structure design is integrated to realize the rapid digging and mixing of large-area shallow soft soil, thereby improving the efficiency of the solidification operation.

[0010] 2. The design of the conveying assembly ensures that the soft soil solidification agent can be uniformly distributed in the mixed soft soil, thereby improving the solidification effect.

[0011] 3. The design of the steering assembly and the rotating motor enables the device to flexibly adjust the working posture and direction, thereby adapting to the needs of different working environments, and the structure of the chain trencher also enables the device to have the ability of deep soil solidification operation.

[0012] 4. By improving the efficiency and quality of the solidification operation, unnecessary solidification costs and time waste are reduced.

[0013] Further, the earth digging assembly comprises an earth digging motor fixedly connected to the inner wall of one end of the frame, an earth digging gear coaxially fixedly connected to the output shaft of the earth digging motor, an earth digging gear chain engaged with the earth digging gear, a plurality of decks detachably connected to the outer periphery of the earth digging gear chain, a conveying gap arranged between adjacent decks, a plurality of inclined guide plates and symmetrical earth digging teeth fixedly connected to each deck, the deck width being greater than the frame interval, and the earth digging gear chain being wrapped around the outer periphery of the frame.

[0014] The beneficial effects of the basic scheme are: 1. Through the driving of the digging motor, the digging tooth chain can rotate continuously and stably, realizing efficient excavation and mixing of soft soil in the transverse direction. The design of the inclined guide plate and the digging tooth on the deck further enhances the excavation and mixing effect, enabling the soft soil and the solidifying agent to be more fully mixed.

[0015] 2. The deck is detachably connected to the outer periphery of the digging tooth chain. This design enables the device to flexibly adjust the number and layout of the deck according to different operating environments and soft soil properties. The digging tooth chain is wrapped around the outer periphery of the frame, enabling the frame design to have certain flexibility to adapt to different depths and widths of soft soil solidification operation requirements.

[0016] 3. The digging motor is fixedly connected to the inner wall of the frame through the support shell. This design enhances the structural stability of the digging assembly, improves the durability and service life of the device. The deck, inclined guide plate, and digging tooth are made of wear-resistant and corrosion-resistant materials, which can adapt to harsh operating environments and reduce maintenance and replacement costs.

[0017] 4. By optimizing the design of the digging assembly, the operating efficiency of the device is improved, and the energy consumption and cost are reduced. The detachable design of the digging tooth chain and the deck facilitates the maintenance and maintenance of the device, reducing downtime and maintenance costs.

[0018] Further, the symmetrical digging teeth are located on both sides of the axial direction of the inclined guide plate, and the digging teeth are directed towards both sides of the deck.

[0019] The beneficial effects of the basic scheme are: The symmetrical digging teeth are located on both sides of the axial direction of the inclined guide plate and directed towards both sides of the deck. This design enables the digging tooth chain to more efficiently excavate and mix soft soil when rotating. The cutting and turning action of the digging teeth and the guiding action of the inclined guide plate together enable the soft soil to be uniformly and fully mixed.

[0020] Further, the digging motor is fixedly connected to the inner wall of the frame through the support shell.

[0021] The beneficial effects of the basic scheme are: 1. The digging motor is fixedly connected to the inner wall of the frame through the support shell, which can effectively prevent the motor from shaking or moving during operation, improving the overall stability of the device. This is crucial for ensuring the normal operation of the device in complex operating environments.

[0022] 2. The support shell can disperse the vibration and impact force generated by the digging motor, reducing the damage to the motor. This not only prolongs the service life of the motor, but also reduces the maintenance and replacement costs of the device.

[0023] Further, the conveying assembly comprises annular sliding grooves located on both sides of the rotating wheel, each of the annular sliding grooves comprises an inner half ring and an outer half ring, the inner half ring is in sliding fit with the outer half ring, the inner half ring is close to the rotating wheel, the outer half ring is away from the rotating wheel, the inner half ring is fixedly connected with the output shaft of the rotating motor, the outer half ring is rotatably connected with the output shaft of the rotating motor, and the inner half ring is communicated with a conveying pipe, the conveying pipe is annularly laid along the frame, a plurality of conveying openings are formed in the outer wall of the conveying pipe, and the outer half ring is communicated with a supply pipe on the side away from the rotating wheel, the supply pipe penetrates through the rotating groove wall and extends upward along the support arm.

[0024] The beneficial effects of the basic scheme are: 1. Through the design of the annular sliding groove and the conveying pipe, uniform spraying of the curing agent is realized. The inner half ring rotates with the rotating wheel, drives the conveying pipe to move along the frame, and uniformly sprays the curing agent through the deck conveying gap into the stirred soft soil.

[0025] 2. The design of the conveying assembly has strong adaptability. The inner half ring and the outer half ring of the annular sliding groove are in sliding fit, which can adapt to different rotating speeds and torques, and avoid the influence of the supply pipe on the rotating motor.

[0026] Further, the conveying pipe is fixedly connected with a protection shell on the side away from the frame, and a plurality of stirring rods are fixedly connected to the protection shell.

[0027] The beneficial effects of the basic scheme are: The setting of the electric control valve effectively prevents the backflow of the curing agent and the soft soil, and ensures the stability and continuity of the spraying. This not only improves the spraying efficiency, but also avoids the waste of resources and environmental pollution.

[0028] Further, the conveying pipe is fixedly connected with a protection shell on the side away from the frame, and a plurality of stirring rods are fixedly connected to the protection shell.

[0029] The beneficial effects of the basic scheme are: The design of the protection shell and the stirring rod further enhances the stirring effect. While the soft soil passes through the inside of the frame, the stirred soft soil is stirred again, which promotes the uniform mixing of the curing agent and the soft soil. The design of the protection shell protects the conveying pipe from external damage and prolongs the service life of the equipment.

[0030] Further, the supply pipe is made of elastic material.

[0031] The beneficial effects of the basic scheme are: The supply pipe is made of elastic material, which can adapt to the vibration and friction during operation and ensure the stable supply of the curing agent.

[0033] The beneficial effects of the basic scheme are: 1. The steering motor drives the steering gear to rotate, which in turn drives the support arm to rotate radially, achieving flexible adjustment of the working direction of the device. This design enables the soft soil solidification device to easily cope with different operating environments and terrain conditions, improving the adaptability and flexibility of the device.

[0034] 2. The meshing transmission of the pinion shaft and the steering gear has the characteristics of high transmission efficiency and strong carrying capacity, which can ensure the stable operation of the steering assembly under long-time and high-load working conditions. The structure of the steering assembly is relatively simple, easy to disassemble and maintain. In the event of a device failure, the problem can be quickly located and repaired, reducing downtime and maintenance costs.

[0035] 3. The flexibility and stability of the steering assembly help improve the operating efficiency of the soft soil solidification device. By quickly adjusting the working direction, the device can more efficiently cover the operating area, reducing repetitive labor and invalid operating time.

[0036] Further, the supply pipe is fixedly connected to the outer periphery of the support arm, the upwardly extending end of the supply pipe is communicated with the output end of a supply pump, the input end of the supply pump is communicated with a soft soil solidification agent mixing tank, and the supply pump is signal connected with a controller.

[0037] The beneficial effects of the basic scheme are: 1. The fixed connection of the supply pipe to the outer periphery of the support arm enhances the structural stability of the entire conveying system. This design reduces the risk of pipe loosening or falling due to vibration or external forces, ensuring the continuity and stability of the solidification agent delivery.

[0038] 2. This design scheme has strong adaptability and can be applied to different types of soft soil solidification operating environments. Whether it is a large-scale engineering project such as a highway, railway, or airport runway, or other occasions requiring soft soil solidification, the device can provide an efficient and stable solidification agent delivery solution.

[0047] The conveying assembly is used for conveying the soft soil stabilizer in several directions in the frame 5, and comprises annular chutes 15 located on both sides of the rotating wheel 16, each of which comprises an inner half ring 23 and an outer half ring 24, the inner half ring 23 is in sliding fit with the outer half ring 24, the inner half ring 23 is close to the rotating wheel 16, the outer half ring 24 is away from the rotating wheel 16, the inner half ring 23 is welded with the output shaft of the rotating motor 4, the outer half ring 24 is in sliding fit with the output shaft of the rotating motor 4, the inner half ring 23 is communicated with a conveying pipe 12, the conveying pipe 12 is annularly laid along the frame 5, a plurality of conveying ports 13 are formed in the outer wall of the conveying pipe 12, the outer half ring 24 is communicated with a supply pipe 2 away from the rotating wheel 16, the supply pipe 2 penetrates through the wall of the rotating groove 3 and extends upward along the support arm 1, an electric control valve and a nozzle are welded in each of the conveying ports 13, the electric control valve is signal connected with the controller, the opening degree of the nozzle close to the both ends of the frame is smaller than that of the central nozzle, the conveying pipe 12 is welded with a protective shell 6 away from the frame 5, a plurality of stirring rods 7 are welded on the protective shell 6, and the supply pipe 2 is made of elastic material.

[0048] The supply pipe 2 is bonded with the outer periphery of the support arm 1, the upward extending end of the supply pipe 2 is communicated with the output end of a supply pump, the input end of the supply pump is communicated with a soft soil stabilizer mixing tank, and the supply pump is signal connected with the controller.

[0049] The specific implementation process is as follows: when large-area shallow soft soil stabilization is carried out, the stirring head needs to be used to step by step penetrate into the soft soil for mixing and stirring of the soft soil stabilizer. Since the area of the stirring head is small, the operation efficiency is not ideal. Based on this reason, the chain transmission structure is designed to design the soil digging assembly.

[0050] As shown in Figure 2 , the support arm 1 installed on the mechanical arm of the excavator supports the rotating motor 4, the rotating wheel 16 welded on the output shaft of the rotating motor 4 is welded with the frame 5, so that the rotating motor 4 on the support arm 1 can rotate the frame 5, and the flexible adjustment of the end of the frame 5 is facilitated. When the soft soil is stabilized, the soil digging motor 18 is turned on, the soil digging gear 17 on the output shaft drives the soil digging gear chain 25 to move around the outer periphery of the frame 5, so as to drive the fixed deck 8, the inclined guide plate 10 and the soil digging tooth 11 on the deck 8 dig the soft soil and push it to the transverse two sides of the deck 8. When deep soft soil stabilization is needed, the frame 5 is erected, and the whole frame 5 is deeply mixed in the soft soil.

[0051] Meanwhile, the adjusted soft soil curing agent is inputted along the support arm 1 through the supply pipe 2 which directly penetrates the support arm 1 and communicates with the outer half ring 24 which does not rotate with the rotation of the frame 5 on the rotating motor 4, avoiding the influence of the rotation on the supply pipe 2, and the soft soil curing agent enters the inner half ring 23 through the annular chute 15, and then enters the conveying pipe 12 through the inner half ring 23, and is uniformly dispersed into the excavated soft soil through the conveying ports 13 distributed at different positions, and the electric control valve is used to prevent the excavated soft soil from entering the conveying port 13 and blocking the conveying pipe 12, since the annular conveying pipe 12 is located inside the frame 5 and needs to have the ability to rotate with the frame 5, the inner half ring 23 is welded with the output shaft of the rotating motor 4 to rotate with it, and the soft soil curing agent output from the conveying gap 9 between the decks 8 is sprayed into the soft soil from the inside of the frame 5 to mix with the soft soil, thereby fully guaranteeing the mixing efficiency of the soft soil and the soft soil curing agent.

[0052] The main working mode of the present application is to vertically erect the frame 5 for deep soft soil excavation, stirring and fixing, or horizontally place the frame 5 for large-scale shallow soft soil curing, and only in these two attitudes of the frame 5, the controller controls the supply pump to reach the maximum soft soil curing agent supply flow rate through the reception of the angular velocity signal of the gyroscope, when the rotating motor 4 rotates the frame 5 to 45° with the mechanical arm, at this time the controller controls the supply pump to enter the minimum supply flow rate or stop supplying, thereby avoiding the waste of the sprayed soft soil curing agent when the frame 5 rotates or the excavator body changes direction, ensuring sufficient supply of the soft soil curing agent in the working state, and reducing the possibility of foreign matter entering the conveying port 13 to block it.

[0053] In addition, when deep soft soil curing is carried out, the gyroscope on the frame 5 detects the attitude of the frame 5 at this time, transmits the signal to the controller to open the deep soft soil excavation and curing mode, at this time the gyroscope continuously detects the angular velocity change of the frame 5 landing and digging into the ground, thereby gradually opening the electric control valve into the ground through the controller, at first the electric control valve is opened the least, and the opened electric control valve corresponds to the nozzle with smaller opening degree, under the premise of the same soft soil curing agent flow rate, the speed of the sprayed soft soil curing agent reaches the fastest at this time, thereby helping the decks 8 and the earth digging teeth 11 to wet the soft soil which has not been excavated, reducing the difficulty of digging, when the frame 5 gradually penetrates into the ground, layer by layer, the electric control valve is opened, and the nozzle with larger opening degree in the center is also opened, the soft soil curing agent is continuously sprayed and mixed with the soft soil with larger pressure, fully utilizing the flow rate of the conveyed soft soil curing agent on the stirred and excavated soft soil, promoting the mixing effect in the deep soft soil fixing and excavation process.

[0054] When shallow soft soil is being solidified, the gyroscope on frame 5 detects its horizontal orientation and activates the shallow soft soil solidification mode via the controller. The gyroscope also detects the orientation of frame 5 and controls the opening of the electrically controlled valve near the ground to initiate the solidification process. As the excavator moves, the soft soil passes under and inside frame 5. At this time, the conveying port 13 near the ground continuously and rapidly sprays soft soil solidifying agent into the pushed-up soft soil through the conveying gap 9. This, combined with the movement of the deck 8, the digging teeth 11, the inclined guide plate 10, and the mixing rod 7, enhances the mixing of the shallow soft soil. To ensure the full effectiveness of the soft soil solidifier and improve the quality and efficiency of solidification, the nozzles at both ends have a smaller opening than the central nozzle, resulting in a consistently faster flow rate. This causes a stronger impact on the soft soil below the horizontal ends of the frame 5. When solidifying shallow soft soil, the frame 5 can be oscillated back and forth using the rotating motor 4, lifting one end of the frame 5 to impact and gather the soft soil towards the center. The gathered soft soil is then mixed with a large amount of solidifier sprayed from the central nozzle with a larger opening, thus promoting the overall mixing efficiency of the soft soil, enhancing the mixing effect, and avoiding uneven distribution of the soft soil after solidification.

[0055] Example 2

[0056] The difference from the above embodiments is that, as shown in the appendix Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: The steering assembly is used to realize the radial rotation of the support arm 1. The steering assembly includes a gear shaft 22 that is fixedly connected to the end pin of the excavator body's mechanical arm. The end of the support arm 1 that is rotatably connected to the mechanical arm has a steering groove 19. The gear shaft 22 is located inside the steering groove 19. A steering motor 20 is fixedly connected inside the steering groove 19. A steering gear 21 is coaxially welded to the output shaft of the steering motor 20. The steering gear 21 meshes with the gear shaft 22.

[0057] The specific implementation process is as follows: the steering motor 20 rotates the steering gear 21 on the tooth shaft 22, drives the support arm 1 welded with the steering motor 20 to rotate at the end of the mechanical arm of the excavator, so as to give the device a more flexible operation mode. When dealing with large-area shallow soft soil, through the cooperation of the steering motor 20 and the rotating motor 4, the device is transversely placed, the support arm 1 and the frame 5 form an "L" shape, and the excavator is started to make the excavated soft soil accumulate on the side of the frame 5. At this time, the inclined guide plate 10 can not only generate a thrust towards the direction of the sprocket chain movement, but also generate a thrust towards the direction of the excavator advancing, reducing the residual soil on the ground and reducing the uniformity of the soft soil solidifying agent. At the same time, the soft soil is also mixed with the soft soil solidifying agent and leaks backward through the gap on the inside of the frame 5, and the protective shell 6 not only protects the conveying pipe 12, but also the stirring rod 7 on it can stir the soft soil again to provide the uniformity of the soft soil solidifying agent. This working mode undoubtedly greatly improves the operation efficiency of the large-area shallow soft soil solidification and reduces the consumption of manpower and resources.
