Description

Technical Field

[0001] The invention relates to the technical field of roadbed construction, in particular to an automatic picking up, feeding, crushing and improved mixing and paving device for collecting stones for filling roadbed. Background Art

[0002] As the foundation of the road surface, the roadbed is a geotechnical structure constructed by excavation or filling. It shoulders the important task of creating the necessary conditions for road paving and subsequent driving operations. It not only bears the static and dynamic loads generated by locomotives, roads and traffic, but also needs to transfer and diffuse these loads deep into the foundation to ensure the stability of the overall road structure.

[0003] Taking lime-improved soil as an example, the traditional roadbed improved soil construction process usually follows a set of established processes. The first step is to fill the roadbed soil. When the filling reaches a certain scale, lime is spread on its surface. Then, excavators and other equipment are used to carry out mixing operations, striving to fully mix the lime and roadbed soil. After the mixing is completed, the mixture is flattened and finally the rolling process is carried out to make the roadbed reach the density required by the design.

[0004] However, with the continuous development and progress of road engineering technology, traditional processes have exposed more and more drawbacks. From the perspective of construction efficiency, the various links in the process lack a tight and smooth connection, resulting in a large amount of time wasted and requiring considerable manpower costs.

[0048] A conveying assembly 6, wherein the conveying assembly 6 is arranged on the top of the driving chassis 1;

[0049] A crushing assembly 5, which is arranged on the top of the conveying assembly 6, and includes a crushing mechanism 51 and a protective frame 52, wherein the protective frame 52 is fixedly mounted on the top of the crushing mechanism 51, and the output end of the crushing assembly 5 is arranged on the input end of the conveying assembly 6;

[0050] A first bucket elevator 4, wherein the input end of the first bucket elevator 4 is arranged at the bottom of the output end of the aggregate frame 21, and the output end of the first bucket elevator 4 is arranged at the top of the crushing mechanism 51 and is located on the inner side of the protective frame 52;

[0053] The paving mechanism 9 is fixedly mounted on the rear end of the driving chassis 1 , and the input end of the paving mechanism 9 is connected to the output end of the spiral conveying and mixing mechanism 8 .

[0054] The driving chassis 1 is a crawler-driven chassis, where the power source outputs torque to the driving wheel. The friction between the driving wheel and the crawler makes the crawler continuously rotate around the driving wheel and the driven wheel. Since the crawler has a large contact area with the ground and strong adhesion, the friction is used to push the entire chassis and the equipment carried forward or backward during the rolling process of the crawler. The supporting wheels roll in the crawler track to ensure the stable operation of the chassis. Even in complex terrain, good passage can be achieved by virtue of the adaptability of the crawler.

[0055] When the cab 11 is in use, it can control the driving telescopic member 22, the picking assembly 3, the first fighter elevator 4, the crushing assembly 5, the conveying assembly 6, the unloading assembly 7, the screw conveying mixing mechanism 8, the paving mechanism 9 and the driving chassis 1 respectively;

[0056] When the picking assembly 3 is in use, the driving assembly 34 provides power to drive the roller 31 to rotate, so that the roller 31 drives 32 to rotate, and the stone is transported to the inner side of the collection frame 21;

[0057] The first fighter elevator 4 can transport the stone output from the bottom of the aggregate frame 21 to the feed inlet of the crushing mechanism 51;

[0058] The crushing assembly 5 includes a crushing mechanism 51 and a protection frame 52. The crushing mechanism 51 is a counter-rotating gear gyratory crusher, which can crush stones exceeding a certain size into a particle size that meets the requirements of roadbed filling. The counter-rotating gear gyratory crusher has an overload protection function to ensure the stable operation of the equipment. The protection frame 52 is installed on the top of the counter-rotating gear gyratory crusher to prevent stones from splashing when crushing stones, thereby increasing safety.

[0059] The conveying assembly 6 is composed of a large conveyor belt, a motor and a protective shell. The motor drives the conveyor belt to move inside the protective shell to convey the crushed stone. The conveyor belt has high strength and wear resistance and can withstand the weight and friction of the stone. A feed port is provided at one end of the top of the protective shell close to the crushing mechanism 51, so that the stone can fall on the conveyor belt. A feed port is also provided at one end of the top of the protective shell close to the unloading frame 74, which is used to convey lime to the top of the stone.

[0060] When the material discharging assembly 7 is in use, lime must first be accumulated on the inner side of the material storage frame 71, and then the second driving motor 75 is started, so that the second driving motor 75 drives the rotating rod 76 to rotate, so that the rotating rod 76 drives the material discharging plate 77 to rotate on the inner side of the circular material discharging cavity 73, so that the lime is transported to the inner side of the material discharging frame 74, and then transported to the upper side of the conveyor belt through the material discharging frame 74. When the second driving motor 75 is in use, the rotation speed can be controlled to control the amount of lime discharging;

[0061] The spiral conveying and mixing mechanism 8 is a spiral conveying mixer, which is mainly composed of a feed inlet, a spiral conveying shaft, stirring blades, a discharge port, a driving device and a shell. The spiral conveying shaft is a core component, which is usually a rotating shaft with spiral blades installed inside the shell. When in use, lime and stone enter the equipment from the feed inlet, and the driving device drives the spiral conveying shaft to rotate. The spiral blades push the lime and stone along the axial direction. During the pushing process, the stirring blades stir the lime and stone to fully mix the lime and stone. Compared with traditional mixing equipment, its mixing efficiency is higher because the pushing action of the spiral blades can continuously update the contact surface of the material and accelerate the mixing process.

[0062] The paving mechanism 9 is a stabilized soil paver, which is mainly composed of a driving device, a hopper, a scraper conveyor, a spiral distributor, a control system and an ironing plate. When in use, first, the stone and lime are transported to the inside of the hopper through the spiral conveying and mixing mechanism 8. After the work starts, the scraper conveyor is started to transport the stabilized soil in the hopper backward to the spiral distributor at a certain speed. In this process, the speed of the scraper conveyor is adjusted according to the paving speed and the required material quantity to ensure a continuous supply of stabilized soil; after the spiral distributor receives the stabilized soil delivered by the scraper conveyor, it distributes it laterally and evenly within the entire working width in front of the ironing plate. Its rotation speed and height can be adjusted according to the requirements of the paving thickness and width. For example, when the paving width needs to be increased, the rotation speed of the spiral distributor can be appropriately increased. , so that the stabilized soil can be distributed over a wider range; as the power chassis 1 moves forward, the ironing plate slides on the stabilized soil. At the same time, the vibrator of the ironing plate vibrates the stabilized soil at a certain frequency and amplitude to reduce the gaps between the particles and preliminarily increase the density of the stabilized soil. Then, the vibrator of the ironing plate is started to further compact the stabilized soil, and the height is automatically adjusted through the floating effect of the ironing plate to make the surface of the spread stabilized soil flat. In this process, the automatic leveling system (if equipped) plays a role. The sensor installed on the ironing plate detects the elevation change of the road surface and feeds back the signal to the control system. The control system adjusts the height of the ironing plate in time to ensure that the flatness of the paving layer meets the requirements. During the whole process, the power chassis 1 moves forward steadily at the set speed to continuously complete the paving and preliminary compaction of the stabilized soil.

[0063] A support seat 13 is fixedly mounted on the front end of the top of the driving chassis 1 , and a support plate 12 is fixedly mounted on the rear end of the top of the driving chassis 1 .

[0066] When in use, when it is necessary to adjust the picking angle of the picking component 3, the driving telescopic member 22 can be started, so that one end of the driving telescopic member 22 supports the side plate 33, so that one end of the side plate 33 rotates around the side of the support frame 2, thereby adjusting the angle of the roller 31.

[0067] The driving assembly 34 includes a power box 341, an overload protector 342, a first driving motor 343, a first pinion 344, a first large gear 345, a transmission shaft 346, a second pinion 347, a second large gear 348 and an output shaft 349.

In this way, the output torque of the first drive motor 343 can be increased, and an overload protector 342 is provided at the power input end of the first drive motor 343. When the maximum power of the first drive motor 343 is exceeded, the first drive motor 343 can be protected.
