Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a mobile mixing device for sea mud soil making on site. Background Art

[0002] Sea mud is a kind of unagglomerated soft fine or ultra-fine particles that are deposited in a still water or slow-flowing water environment and formed by physical, chemical and biochemical reactions. It belongs to modern recent sediments. Sea mud generally has a high water content, a high clay content, poor drainage, and extremely low strength. Some sea muds have a relatively high organic matter content. It is a special type of soil that is difficult to use directly in engineering. Generally, it needs to be mixed and solidified before it can be processed as a resource. In the patent application in patent number CN113547634A, a low-dust mixing device for engineering materials is disclosed. The mixing device in this application can only mix engineering materials, such as sand, gravel, cement and other non-sticky materials, and is not suitable for mixing sea mud that is highly viscous and difficult to stir and separate. Under construction conditions, the drive shaft, as the weak link of the mechanical transmission structure, faces huge challenges. When the resistance required for the drum to stir the sea mud increases, the drive shaft needs to transmit greater force. Exceeding its load-bearing range will cause it to break, affecting the service life of the drive shaft. Once the drive shaft breaks, the equipment will continue to operate, causing the broken drive shaft to swing back and forth, which will not only damage surrounding equipment, but may also pose a safety hazard to the staff.

[0003] In the prior art, hydraulic cylinders are arranged at both ends of the drum, and the drum is lifted and lowered by extending or shortening the hydraulic cylinders, which has a simple structure. However, during use, since the equipment adopts a single-sided drive, the fixed end of the hydraulic cylinder on one side is fixed to the frame, and the movable end is fixed to the transmission box; the fixed end of the hydraulic cylinder on the other side is fixed to the frame, and the movable end is directly connected to the side plate of the drum. During use, since the weight of the transmission box is large and the drum is always in a horizontal state, it is necessary to ensure that the hydraulic cylinders on both sides maintain synchronous lifting and lowering. However, due to the large weight difference at both ends, the precision requirements for the hydraulic parts are very high, and imported parts need to be used, which is very expensive. At the same time, the cleanliness requirements for the hydraulic oil are also very high. In addition, the operating environment of the equipment is complex, and the hydraulic oil needs to be replaced more frequently, which further increases the cost. In addition, when mixing sea mud, due to the high moisture content and high viscosity of sea mud, the resistance encountered by the drum during rotation increases, and the two ends of the drum are easily subjected to unbalanced forces when lifting and lowering, causing the drum to tilt. Once the drum tilts, the gear shaft connecting the drum and the gear box will be damaged or even broken, directly affecting the service life of the equipment. In addition, under some extreme working conditions, such as when the sea mud pile is huge, the mixing equipment may not work normally because it cannot automatically adjust the height of its own equipment.

[0004] Therefore, there is an urgent need in the art for a high-power mixing device that can adjust the overall lifting of the equipment, ensure the service life of the equipment, mix the sea mud in accordance with the characteristics of the sea mud, and reduce costs. Summary of the invention

[0018] Preferably, climbing ladders are provided on both sides of the arched frame.

[0019] Compared with the prior art, the utility model has achieved the following beneficial technical effects:

[0020] 1. The mobile mixing equipment for sea mud soil formation on site provided by the utility model is characterized in that each of the mixing claw arrays is bent toward the middle of the cylinder, so that each of the mixing claw arrays is spirally coiled on the cylinder. When the mixing drum rotates, the spirally arranged mixing claws can throw the sea mud from both sides to the middle, and the sea mud becomes a pile after free fall, thereby avoiding excessive dispersion after throwing up. Due to the high viscosity of the sea mud, the mixing claws are arranged in a shape with an upper portion bent. After multiple tests and certifications, the axial distance between each two adjacent mixing claws in the same mixing claw array is 5-10 times the required particle size of the mixed sea mud, so that the crushing requirements of the particle size of the mixed sea mud can be met when the sea mud is turned over, and the turning and throwing effect of the sea mud is better.

[0021] 2. The transmission assembly provided by the utility model, when the sea mud is mixed, the sea mud is highly viscous and difficult to separate, and the resistance to the drum is large, that is, a transmission assembly capable of transmitting high power is required to drive the drum to rotate. By setting a power distribution box and a gear box, the structure is compact, and the gear shaft transmission is adopted to distribute the power generated by the engine through the gears in the power distribution box. Compared with the transmission shaft adopted in the prior art, the transmission assembly connection structure of the equipment is strong and not prone to failure. Even when transmitting a large force, it will not cause wear and breakage of the gear shaft, thereby ensuring the service life of the transmission parts and reducing the cost. Furthermore, by setting a hydraulic clutch, when the hydraulic clutch is closed, the transmission assembly operates normally, driving the mixing drum to rotate, and performing the turning and mixing operation on the sea mud. When the hydraulic clutch is disconnected, the transmission assembly cannot operate, and the mixing drum cannot rotate, thereby ensuring safety when not working. Moreover, the hydraulic clutch device can slip, which plays a buffering role, protects the transmission parts in the equipment, and ensures the service life of the transmission parts.

[0022] 3. The integral lifting assembly provided by the utility model can lift or lower the mixing drum and the arch frame as a whole. Existing mixing equipment can only lift the mixing drum, or cannot lift automatically. Then, under extreme working conditions, due to the high viscosity of sea mud, when the mixed sea mud pile and the sea mud pile after flipping are high enough, the existing mixing equipment will be trapped in place and cannot continue to operate. The integral lifting assembly in this equipment overcomes this problem. When such an extreme working condition occurs during the movement of the equipment, the arch frame and the drum can be lifted as a whole, crossing the sea mud pile, or flipping from the top of the sea mud pile, ensuring the normal construction of the equipment. In addition, due to the high viscosity of sea mud, the resistance it generates on the drum is large. During the process of the drum turning over the sea mud, the uneven force on both ends of the drum will cause the gear shaft between the drum and the transmission structure to break. The integral lifting assembly in this equipment enables the arch frame and the mixing drum to rise and fall at the same time, and the mixing drum always remains horizontal. Even if the arch frame is skewed due to the uneven road surface at the sea mud construction site or the uneven resistance of the drum to the sea mud, the transmission shaft between the mixing drum and the arch frame will tilt with the tilt of the arch frame, while the angle between the mixing drum and the transmission shaft will not change, no bending force will occur, and the transmission shaft will not be damaged, thereby ensuring the service life of the transmission shaft and reducing costs.

[0023] 4. The mobile mixing equipment for sea mud soil formation provided by the utility model adopts a crawler walking device with a simple transmission structure, realizes the on-site operation of mixing and solidifying sea mud, and realizes the mobility of the equipment. Due to the high viscosity of sea mud, when mixing sea mud, a larger power is transmitted through a high-power transmission component to drive the mixing claws on the mixing drum to grab the sea mud and flip it backwards. Under extreme working conditions, the equipment can be lifted as a whole through the overall lifting component to cross the sea mud pile. The various components in the equipment cooperate with each other and work together to achieve the mixing of high-viscosity sea mud and ensure the service life of the equipment.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] The utility model provides a mobile mixing device for sea mud soil making on site, such as Figure 1-Figure 7 As shown, it includes an arch frame 1, a mixing drum 2, two symmetrically arranged traveling components, a transmission component, two symmetrically arranged integral lifting components and a control device. A traveling component is installed on each side of the arch frame 1, and the traveling component can drive the arch frame 1 to travel. A cab 3 is arranged above the arch frame 1, and the control device is arranged in the cab 3. The mixing drum 2 is installed inside the arch frame 1, one end of the mixing drum 2 is fixedly connected to the transmission component, and the other end of the mixing drum 2 is rotatably connected to the arch frame 1. The transmission component and the traveling component are both connected to the control device. The integral lifting component is connected to the arch frame 1 and can lift the arch frame 1 and the mixing drum 2 as a whole. The transmission component includes a gear-driven power distribution box 10 and a gear box 11. The input shaft of the power distribution box is connected to the engine, the engine is connected to the control device, and the gear box 11 is connected to the mixing drum 2.

[0036] Specifically, after the operator enters the cab 3, he controls the walking assembly to drive the entire equipment to walk at the solidification site by operating the control device, and controls the transmission assembly to transmit power to the mixing drum 2, driving the mixing drum 2 to rotate, so as to realize the turning and mixing of the sea mud at the solidification site. Due to the high viscosity of sea mud, when mixing sea mud, high-power power is transmitted through the transmission assembly, and gear transmission is used instead of traditional transmission shaft transmission, which reduces the wear and replacement of the transmission shaft and ensures the service life of the transmission shaft; the transmission assembly drives the mixing claw 33 on the mixing drum 2 to grab the sea mud and turn it backwards. Under extreme working conditions, the overall lifting assembly can be used to lift the equipment as a whole and cross the sea mud pile, reducing the situation where the drum drive shaft is damaged due to uneven force at both ends of the mixing drum, and ensuring the service life of the components. The various components in this equipment cooperate with each other and work together to achieve the mixing of high-viscosity sea mud and ensure the service life of the equipment.

[0037] The outer surface of the mixing drum 2 is provided with a plurality of mixing claw arrays, each of which is bent toward the middle of the drum, and the axial distance between every two adjacent mixing claws 33 in the same mixing claw array is 5-10 times the required particle size of the mixed sea mud.

[0038] Specifically, the mixing claw array on the outer surface of the mixing drum 2 is evenly arranged around the cylinder and forms a spiral shape, so that the sea mud missed by the mixing claws in the previous mixing claw array is taken over and thrown by the mixing claws 33 of the next mixing claw array, and the sea mud is gathered and thrown out in the middle. The ends of the mixing claws 33 are arranged in a curved shape, which is conducive to crushing large pieces of sea mud, and can gather sea mud like a rake, so that the sea mud can be better grasped for mixing. In addition, it has been verified through multiple tests that the axial distance between every two adjacent mixing claws 33 in the same mixing claw array is 5-10 times the required particle size of the mixed sea mud, which can meet the crushing requirements of the mixed sea mud particle size when turning over the sea mud, and the turning over effect of the sea mud is better.

[0039] In this embodiment, the angle between the straight line where the mixing claw array bent toward the middle of the cylinder is located and the central axis of the mixing drum 2 is the helical angle θ, and the range of the helical angle θ is 15 degrees to 17 degrees. Generally speaking, the angle range of the helical angle will be adjusted according to the requirements of the particle size of the mixed sea mud. The mixing claw array is set to 5-6 groups, and two adjacent mixing claw arrays are staggered. Each mixing claw array includes a number of mixing claws 33 arranged in sequence. One end of the mixing claw 33 is vertically fixedly connected to the mixing drum 2, and the other end of the mixing claw 33 is bent. The mixing claws 33 at the corresponding positions on the two symmetrical sides of the mixing claw array bent toward the middle of the cylinder are bent in opposite directions. The mixing claws with this structure can more effectively scoop up the sea mud and meet the crushing requirements of the particle size of the mixed sea mud.

[0040] In this embodiment, a walking assembly is symmetrically connected to each side of the arch frame 1, and the walking assembly is a crawler walking assembly, which includes a crawler bracket 4, which is fixedly installed on the side of the arch frame 1 by bolts, and a crawler driving wheel 5 and a crawler driving device are installed at the front end of the crawler bracket 4. The crawler driving device is a hydraulic motor 6, which is connected to the crawler driving wheel 5 and is used to provide power for the crawler driving wheel 5. A crawler driven wheel 7 is installed at the rear end of the crawler bracket 4 to adjust the tightness of the crawler 9, and a plurality of crawler support wheels 8 are installed in the middle of the crawler bracket 4 to support the crawler 9. The crawler driving wheel 5 and the crawler driven wheel 7 are meshed and installed with crawlers 9 on the outside, and the crawler driving device is connected to the control device. The rotation of the hydraulic motor 6 is controlled by a control device to drive the movement of the crawler driving wheel 5, thereby driving the rotation of the crawler 9, so that the mixing equipment can move, ensuring that the mixing equipment can mix the sea mud at the solidification site, realizing the mobility of the equipment, and saving costs and time compared with the existing technology of transporting sea mud by using a mixing station.

[0041] In this embodiment, one end of the power distribution box input shaft 12 is fixedly connected to the engine, and the other end of the power distribution box input shaft 12 is connected to the power distributor 13 in the power distribution box 10. A distribution box gear 14 and a plurality of additional power gears 15 are provided in the power distribution box 10. The distribution box gear 14 and the plurality of additional power gears 15 are all meshed with the gears on the power distribution box input shaft 12. The upper end gear 16, four intermediate gears 17 and the lower end gear 18 are meshed and connected in sequence from top to bottom in the gear box 11. The gear shaft of the distribution box gear 14 shares a gear shaft with the gear shaft of the upper end gear 16, and the gear shaft of the lower end gear 18 is fixedly connected to the mixing drum 2. The upper end gear 16 and the four intermediate gears 17 are all fixedly mounted on the corresponding gear shafts in the gear box 11, and each gear shaft is mounted on the side wall of the gear box 11 through a bearing. The plurality of additional power gears 15 are fixedly mounted on the corresponding gear shafts in the power distribution box 10, and each gear shaft is mounted on the side wall of the power distribution box 10 through a bearing.

[0042] In this embodiment, the power distribution box input shaft is meshed and connected in sequence from the input end to the output end with the first gear 19 of the power distributor, the hydraulic clutch 20 and the second gear 21 of the power distributor. The first gear 19 of the power distributor is meshed with the distribution box gear 14, the second gear 21 of the power distributor is meshed with the additional power gear 15, the hydraulic clutch 20 is connected to the hydraulic valve 22, and the hydraulic valve 22 is connected to the control device.

[0043] Specifically, the transmission assembly provided by the present device can transmit high-power power. By setting a power distribution box 10 and a gear box 11, the power generated by the engine is distributed through the power distributor 13 in the power distribution box 10 by using gear shaft transmission. The second gear 21 of the power distributor meshes with two additional power gears 15 to transmit power to additional devices that require power, such as oil pumps or air conditioning compressors; the first gear 19 of the power distributor meshes with the distribution box gear 14, and the distribution box gear 14 and the upper end gear 16 of the gear box 11 share a gear shaft. The rotation of the first gear 19 of the power distributor drives the distribution box gear 14 to rotate, and then drives the common gear shaft to rotate, and then drives the upper end gear 16 of the gear box 11 to rotate, so as to transmit power to the gear box 11. In the prior art, a universal transmission shaft is used to transmit power. However, due to the high viscosity of sea mud, sea mud requires a lot of power when it is turned over and mixed. If the power is insufficient or the universal transmission shaft is damaged, the mixing drum will be stuck in the sea mud and cannot rotate, and even a great safety hazard will occur. This equipment adopts gear transmission in the transmission component to replace the universal joint transmission shaft transmission, which reduces the wear and breakage of the transmission shaft, ensures the service life of the transmission parts, and also achieves the technical effect of compact structure.

[0044] In addition, by setting the hydraulic clutch 20, the control device controls the "engagement" and "disengagement" of the hydraulic clutch 20 by controlling the hydraulic valve 22. When the hydraulic clutch 20 is "engaged", the transmission component operates normally, driving the mixing drum 2 to rotate, and the sea mud is turned over and mixed. When the hydraulic clutch 20 is "disengaged", the transmission component cannot operate and the mixing drum 2 cannot rotate, thereby ensuring safety when not in operation. Because the mixing drum 2 cannot rotate in the non-operating state, if there is a foreign object in front, the rotation of the mixing drum 2 will drive the turning of the foreign object, causing a safety hazard. At the same time, the rotation of the mixing drum 2 in the non-operating state will increase the energy consumption of the mixing drum 2. In addition, since the hydraulic clutch 20 can be "engaged" and "disengaged", that is, it can slip, it has a certain impact resistance. Because when the load on the mixing drum 2 is large, the hydraulic clutch device slips, which plays a buffering role, protects the transmission parts in the device, and ensures the service life.

[0045] In this embodiment, an integral lifting assembly is respectively arranged on both sides of the arch frame 1, and the integral lifting assembly includes two lifting hydraulic cylinders 23, a positioning inner cylinder 24 and a guide outer cylinder 25. The lifting hydraulic cylinder 23 is connected to the control device, and the guide outer cylinder 25 is slidably sleeved on the outer periphery of the positioning inner cylinder 24. The positioning inner cylinder 24 is vertically fixedly connected to the crawler bracket 4, and the side end of the guide outer cylinder 25 is fixedly connected to the arch frame. The cylinder end of the lifting hydraulic cylinder 23 is fixedly connected to the arch frame 1, and the piston rod end of the lifting hydraulic cylinder 23 is fixedly connected to the inner side of the crawler bracket 4.

[0046] Specifically, the integral lifting assembly in the present device can lift or lower the mixing drum 2 and the arch frame 1 as a whole. By controlling the lifting hydraulic cylinder 23, the piston rod end and the cylinder end of the lifting hydraulic cylinder will produce relative movement, and the cylinder end will drive the arch frame 1 to rise and fall along the positioning inner cylinder 24, and the lifting and lowering of the arch frame 1 will drive the lifting and lowering of the mixing drum 2. In the prior art, the mixing equipment can only lift the mixing drum 2. Due to the high viscosity of sea mud, there will be particularly large sea mud piles at the operation site. When in extreme working conditions, the sea mud pile that needs to be turned over and the sea mud pile after turning over are large enough to make the entire equipment stagnant, the integral lifting assembly in the present device can drive the mixing drum and the arch frame to be lifted as a whole, thereby crossing the sea mud pile and realizing the continued operation of the equipment.

[0047] In addition, in the prior art, the mixing equipment can only lift the mixing drum 2, and the mixing drum 2 is required to be horizontal, but the main transmission part of the mixing drum 2 is on one side of the arch frame 1, and the unknown load at the sea mud solidification site makes the loads on both sides of the mixing drum 2 unbalanced, so the mixing drum 2 and the transmission shaft of the transmission part will have bending force, resulting in damage to the transmission shaft. The solution in the prior art is to set a synchronous valve, but the synchronous valve has high requirements for the cleanliness of the hydraulic oil and requires frequent replacement of the hydraulic oil. Once the oil output at both ends of the synchronous valve is different, the mixing drum 2 cannot be raised or lowered horizontally, which will also cause the mixing drum 2 and the transmission shaft of the transmission part to have bending force, damaging the transmission shaft. The integral lifting assembly in the present device enables the arch frame 1 and the mixing drum 2 to be lifted and lowered simultaneously, and the mixing drum 2 always maintains a horizontal state. Even if the arch frame 1 is skewed, the mixing drum 2 and the transmission assembly connected to the mixing drum 2 will be skewed along with the skew of the arch frame 1, while the angle between the mixing drum 2 and the transmission assembly will not change, and there will be no bending force, and there will be no damage to the transmission shaft, thus ensuring the service life of the transmission shaft. Moreover, the present device no longer requires high-precision hydraulic oil and synchronous valves, and there is no need for frequent oil changes, thus reducing costs. In addition, the four lifting hydraulic cylinders 23 on the crawler bracket 4 support the overall lifting of the mixing drum 2 and the arch frame 1, which strengthens the support force of the equipment lifting compared to the original two lifting hydraulic cylinders.

[0048] In this embodiment, the integral lifting assembly further includes a transverse connecting plate 26 and a lateral connecting plate 27 connected to each other, the positioning inner cylinder 24 is fixedly connected to the upper surface of the transverse connecting plate 26, and the lower end of the lateral connecting plate 27 is fixedly connected to the outer side of the crawler support 4. By providing the transverse connecting plate 26 and the lateral connecting plate 27, the positioning inner cylinder 24 is supported.

[0049] In this embodiment, a lifting cylinder 28 and a road-clearing shovel 29 extending to the front of the crawler support 4 are respectively installed on both sides of the arch frame 1. The lifting cylinder 28 is connected to the control device, and the cylinder end of the lifting cylinder 28 is fixedly connected to the lateral connecting plate 27. The piston rod end of the lifting cylinder 28 is connected to the road-clearing shovel 29. The shovel body of the road-clearing shovel 29 is pear-shaped with a small front and a large back, and the shovel tip of the shovel body includes two concave arc-shaped working surfaces. By operating the control device, the lifting cylinder 28 works, and the relative movement of the piston rod end and the cylinder end of the lifting cylinder 28 will drive the lifting of the road-clearing shovel 29. By setting the road-clearing shovel 29, it is realized to clean the walking road in front of the mixing equipment to ensure normal walking.

[0050] In this embodiment, a rear baffle 30 is provided at the upper part of the opening of the arch frame 1 at the rear end of the arch frame 1, one end of the rear baffle 30 is rotatably connected to the arch frame 1 through a hinge shaft, and a driving cylinder 31 for driving the rear baffle 30 to open upward and close downward is provided between the rear baffle 30 and the arch frame 1, and the driving cylinder 31 is connected to the control device.
