Description

Technical Field

[0001] This invention relates to the field of material conveying equipment for concrete mixing plants, and more specifically to a material conveying system for a concrete mixing plant. Background Technology

[0002] In the production process of a concrete mixing plant, the precise and efficient transport of aggregates (such as sand, gravel, and crushed stone) from storage silos to batching silos is a crucial step in ensuring the continuous operation of the mixing plant. Currently, the aggregate transport technologies commonly used in the industry are mainly divided into two categories: one is manual assisted transfer using loaders, where operators drive loaders to scoop aggregates from storage silos, transport them to the top of the batching silos, and unload them; the other is the use of fixed belt conveyors, which continuously transport aggregates from storage silos to batching silos via conveyor belts.

[0003] However, the aforementioned existing technical solutions have significant technical defects in practical applications, which seriously affect the production safety, efficiency, environmental protection, and space utilization of the mixing plant:

[0004] Significant safety hazards exist: As the centralized material storage area of ​​the mixing plant, the storage silo area typically requires the installation of multiple storage and transfer devices. Frequent material inspections and equipment maintenance by workers result in a complex environment and frequent overlap of personnel and mobile equipment (especially loaders). Blind spots of loaders during transfers, shifts in the center of gravity when materials are dumped, and exposed transmission components of belt conveyors all easily lead to collisions, crushing, or entanglement accidents, posing a significant threat to the personal safety of workers.

[0005] Low conveying efficiency: When using loaders for transportation, the conveying efficiency is inherently limited by the loader's single scooping capacity, round-trip travel distance, and unloading waiting time. This makes it difficult to meet the continuous production needs of large-scale mixing plants, often resulting in material shortages in the batching bins and affecting overall production efficiency. While belt conveyors have continuous conveying capabilities, their start-stop response is slow due to limitations in the conveying speed of the conveyor belt and the material accumulation angle.

[0006] Poor environmental performance: During the shoveling, transporting and unloading process, aggregates are easily spilled from the edge of the bucket, causing dust on the ground; at the same time, the impact of dumping materials will generate a large amount of dust, and this type of dust is difficult to be effectively treated by centralized collection devices, resulting in dust concentration exceeding the standard in the working area, polluting the surrounding environment, and failing to meet the current environmental protection regulations for dust emissions from industrial production; in addition, spilled aggregates require additional manpower to clean up, further increasing operating costs.

[0007] Large space occupation: Sufficient space must be reserved between the storage bins and the batching bins to accommodate the loader's driving, turning and unloading operations, which forces an increase in the distance between the two. Belt conveyors, due to their structural characteristics, require fixed layout space, and a support frame must be set up to ensure the stability of material conveying, further increasing the site area occupied. This reduces the overall layout flexibility of the mixing plant, making it particularly unsuitable for small mixing plants or renovation and expansion projects with limited site space.

[0067] The advantages of the above technical solution, which differs from the prior art, are as follows: In the material conveying system of the concrete mixing plant of the present invention, the unloading end of the conveying pipe assembly is placed in the area for material suction. The first moving mechanism moves horizontally, thereby driving the conveying pipe assembly to move horizontally as well, so that the unloading end of the conveying pipe assembly can suction material horizontally. Since the first retractable conveying pipe can extend and retract horizontally, when the first moving mechanism moves forward horizontally, the first retractable conveying pipe also moves forward horizontally simultaneously, so that the unloading end of the conveying pipe assembly can suction material at any position horizontally. Since the support mechanism is rotatable to adjust the rotation angle of the conveying pipe assembly in the horizontal direction, when the material in the horizontal direction of the first station has been completely suctioned, the second moving mechanism moves along the horizontal longitudinal direction of the moving plate to the second station, simultaneously driving the conveying pipe assembly to move horizontally to the second station to continue suctioning material. This process is repeated until the material is completely suctioned. The moving plate moves horizontally in the longitudinal direction, thereby driving the conveying pipe assembly to move horizontally in the longitudinal direction as well. This, in conjunction with the horizontal lateral movement of the first moving mechanism, achieves two-dimensional XY movement of the suction end within the horizontal plane. The second moving mechanism works in conjunction with the first moving mechanism to achieve two-dimensional horizontal movement of the conveying pipe suction end. This allows for precise adaptation to storage silos of different locations and specifications, improving the versatility and adaptability of the device. It eliminates the need to reserve space for loader travel and turning, significantly reducing the space occupancy between storage and batching silos. It replaces the manual driving and transfer of traditional loaders, avoiding cross-operation between personnel and mobile equipment, and eliminating safety hazards caused by blind spots and center of gravity shifts in loader operation. Simultaneously, the conveying pipe assembly is a closed structure with no exposed transmission components, preventing personnel entanglement risks and significantly reducing the accident rate. It also improves environmental friendliness, as the conveying pipe assembly is a closed channel, allowing materials to be sucked and unloaded in a closed environment, reducing aggregate spillage and dust generation. Furthermore, it improves conveying efficiency and reduces space occupancy.

[0129] Please see Figures 1 to 7 This embodiment relates to a material conveying system for a concrete batching plant, wherein the material conveying system for the concrete batching plant in this embodiment is applied to the conveying of aggregates in the concrete batching plant. Specifically, a material conveying system for a concrete batching plant includes:

[0130] A power mechanism 100 is provided to supply suction negative pressure to the gas-solid separation box 200 and the conveying pipe assembly 1. The power mechanism 100 is the power source component that provides negative pressure suction power to the entire conveying system, and is the energy supply unit for realizing the "suction-type conveying" of materials. Specifically, in this embodiment, as... Figures 1 to 7 As shown, the power mechanism 100 includes a prime mover and a vacuum fan. The prime mover is connected to the vacuum fan and is used to drive the vacuum fan to start and stop. The gas-solid separation box 200 is connected to the vacuum fan through an air pipe 600. Preferably, in this embodiment, the prime mover is an electric motor. In other embodiments, the prime mover is an engine. Alternatively, a vacuum pump can be used to replace the vacuum fan in this embodiment. After the vacuum fan starts, a stable negative pressure environment is formed inside the gas-solid separation box 200 and the entire conveying pipe assembly 1. The pressure difference is used to draw the aggregate in the storage bin 400 from the suction end of the conveying pipe assembly 1, driving the material to flow along the conveying pipe and finally fall into the gas-solid separation box 200, and then from the gas-solid separation box 200 into the batching bin 300. Compared to the mechanical shoveling of existing loaders and the friction conveying of belt conveyors, the negative pressure suction power mechanism 100 can realize the closed conveying of materials, reducing dust diffusion from the source; at the same time, the power output is stable, and the suction force can be controlled by adjusting the power parameters (such as the fan speed) to adapt to the conveying needs of aggregates of different particle sizes and avoid material blockage or insufficient conveying.

[0131] A gas-solid separation box 200 is connected to the power mechanism 100 via an air pipe 600. The gas-solid separation box 200 is used for filtering and purifying gas and storing materials. Specifically, it separates materials from the carried gas during the suction and conveying process, achieving purified gas emission and material collection and storage. During operation, dust-laden gas carrying aggregate enters the gas-solid separation box 200. After purification, the gas is discharged from the power mechanism 100. The material is intercepted within the gas-solid separation box 200 and deposited under gravity, eventually falling into the batching silo 300 through the bottom pipe. This solves the problem of centralized dust control in existing technologies, achieving efficient gas-solid separation, and ensuring that the purified gas emissions meet environmental standards. Simultaneously, it temporarily buffers the material, preventing secondary dust generation caused by direct impact on the batching silo 300 and improving conveying stability.

[0132] A batching silo 300 is connected to the gas-solid separator 200 via pipelines. The batching silo 300 receives and temporarily stores aggregates conveyed by the conveying device, providing a material storage unit for precise batching in subsequent concrete mixing processes. The top of the batching silo 300 is connected to the gas-solid separator 200 via pipelines, and the batching silo 300 receives materials conveyed by the gas-solid separator 200. The batching silo 300 and the gas-solid separator 200 work together to achieve a smooth material transition, avoiding uneven material accumulation caused by the impact feeding during unloading by existing loaders. The closed feeding method further reduces dust and improves the environmental friendliness of the working environment.

[0133] The conveying pipe assembly 1 has two ends: one for suctioning material and the other for unloading material. The unloading end of the conveying pipe assembly 1 is connected to the gas-solid separation box 200 to unload the material. The conveying pipe assembly 1 is a tubular structure that carries and conveys material, serving as the core channel for material transport. Its two ends respectively perform the functions of suctioning and unloading material, and it is adjustable to adapt to different conveying distances and positional requirements. The conveying pipe assembly 1 includes a first telescopic conveying pipe 11, which can extend and retract horizontally, serving as a tubular component for adjusting the horizontal conveying distance. Through the horizontal extension and retraction adjustment of the first telescopic conveying pipe 11, the horizontal distance between the storage silo 400 and the batching silo 300 can be precisely adapted without reserving additional space for movement. In this embodiment, the material is aggregate (such as sand, gravel, etc.) from a concrete mixing plant.

[0134] A support mechanism 2 is rotatably configured to adjust the horizontal rotation angle of the conveying pipe assembly 1. The first retractable conveying pipe 11 is mounted on the support mechanism 2, which is used to support the first retractable conveying pipe 11 and ensure its structural stability during the conveying process. The support mechanism 2 is a support structure used to support and mount the first retractable conveying pipe 11 and is rotatably configured to adjust the horizontal rotation angle of the conveying pipe assembly 1.

[0135] The storage bin 400 is used to store materials; specifically, it stores materials to be conveyed (sand, gravel, etc.), providing a material source for the conveying device. The storage bin 400 provides a stable material source for the conveying system and also provides a supporting foundation for the installation and movement of the first moving mechanism 3. The storage bin 400, in conjunction with the first moving mechanism 3, enables flexible movement of the suction end within the storage bin 400, avoiding the problem of existing loaders frequently needing to enter and exit the storage bin 400 area, reducing cross-operation between personnel and equipment, and improving operational safety.

[0136] And a first moving mechanism 3, which is movably mounted on the storage bin 400;

[0137] The system includes a second moving mechanism 4, which is mounted on the first moving mechanism 3. The unloading end of the conveying pipe assembly 1 is mounted on the second moving mechanism 4. The first moving mechanism 3 moves horizontally to drive the second moving mechanism 4 and the conveying pipe assembly 1 to move horizontally. The first moving mechanism 3 is a movable driving structure used to drive the conveying pipe assembly 1 and the second moving mechanism 4 to move horizontally, adjusting the position of the conveying pipe suction end on the horizontal plane to accommodate storage bins 400 of different lengths. Its core function is to move horizontally, thereby driving the conveying pipe assembly 1 to move horizontally. The first moving mechanism 3 enables automatic horizontal movement of the suction end of the conveying pipe assembly 1, allowing the unloading end of the conveying pipe assembly 1 to suction material at any position horizontally, replacing the manual driving and transfer of traditional loaders, avoiding cross-operation between personnel and mobile equipment, and reducing the risk of collisions, crushing, and other safety accidents. The coordinate system is based on the horizontal axis (X-axis), the vertical axis (Y-axis), and the Z-axis (Z-axis).

[0138] Furthermore, the second moving mechanism 4 is used to move in the horizontal longitudinal direction of the first moving mechanism 3, thereby driving the delivery tube assembly 1 to move in the horizontal longitudinal direction. The second moving mechanism 4 is a secondary moving structure disposed on the first moving mechanism 3, used to drive the delivery tube assembly 1 to move in the horizontal longitudinal direction, cooperating with the first moving mechanism 3 to achieve two-dimensional movement adjustment of the suction end in the horizontal plane. Its core function is to move the moving plate 32 in the horizontal longitudinal direction, thereby driving the delivery tube assembly 1 to move in the horizontal longitudinal direction, cooperating with the horizontal lateral movement of the first moving mechanism 3 to achieve two-dimensional XY movement of the suction end in the horizontal plane. The second moving mechanism 4 works in conjunction with the first moving mechanism 3 to achieve two-dimensional horizontal movement of the suction end of the conveying pipe. This allows for precise adaptation to storage silos 400 in different locations and of different specifications, improving the versatility and adaptability of the device. It eliminates the need to reserve space for loader travel and turning, significantly reducing the space occupancy between the storage silo 400 and the batching silo 300, thus meeting the site constraints of small mixing plants or expansion projects. Automated two-dimensional movement replaces manual operation, further improving conveying efficiency and avoiding conveying delays caused by human error.

[0139] Specifically, in the material conveying system of the concrete mixing plant in this embodiment, the unloading end of the conveying pipe assembly 1 is placed in the material suction area for suction operation. The power mechanism 100 is started, and a stable negative pressure environment is formed inside the gas-solid separation box 200 and the entire conveying pipe assembly 1 through the air pipe 600. Under the action of negative pressure, the material in the storage bin 400 is sucked into the pipeline from the suction end of the conveying pipe assembly 1. The material is conveyed along the conveying pipe assembly 1 to the gas-solid separation box 200. The dust-laden gas entering the gas-solid separation box 200 is purified, and the purified gas is extracted by the power mechanism 100 through the air pipe 600 and discharged in compliance with standards. The material is deposited at the bottom of the gas-solid separation box 200 under the action of gravity. The first moving mechanism 3 moves horizontally, thereby driving the conveying pipe assembly 1 to move horizontally. The first retractable conveying pipe 11 can extend and retract horizontally. When the first moving mechanism 3 moves forward horizontally, the first retractable conveying pipe 11 also moves forward horizontally, allowing the discharge end of the conveying pipe assembly 1 to suck up material at any position horizontally. Since the support mechanism 2 is rotatable to adjust the rotation angle of the conveying pipe assembly 1 horizontally, once the material at the first station has been sucked up horizontally, the second moving mechanism 4 moves along the horizontal longitudinal direction of the moving plate 32 to the second station, simultaneously moving the conveying pipe assembly 1 horizontally to continue sucking up material. This process is repeated until all material is sucked up. The horizontal longitudinal movement of the moving plate 32, in turn, moves the conveying pipe assembly 1 horizontally, cooperating with the horizontal lateral movement of the first moving mechanism 3 to achieve two-dimensional XY movement of the suction end in the horizontal plane. The second moving mechanism 4 works in conjunction with the first moving mechanism 3 to achieve two-dimensional horizontal movement of the suction end of the conveying pipe. This allows for precise adaptation to storage bins 400 of different locations and specifications, enhancing the versatility and adaptability of the device. It eliminates the need for reserved space for loader travel and turning, significantly reducing the space occupancy between the storage bin 400 and the batching bin 300. It replaces the manual driving and transfer of traditional loaders, avoiding cross-operation between personnel and mobile equipment, and eliminating safety hazards caused by blind spots and center of gravity shifts in loader operation. Simultaneously, the conveying pipe assembly 1 is a closed structure with no exposed transmission components, preventing personnel entanglement and significantly reducing the accident rate. It also improves environmental friendliness, as the conveying pipe assembly 1 is a closed channel where materials are suctioned and unloaded in a closed environment, reducing aggregate spillage and dust generation. Furthermore, it improves conveying efficiency and reduces space occupancy.

[0140] Optionally, in some embodiments, such as Figures 1 to 7As shown, the conveying pipe assembly 1 also includes a second retractable conveying pipe 12, which can extend and retract vertically. One end of the second retractable conveying pipe 12 is connected to the first retractable conveying pipe 11, and the other end is mounted on the second moving mechanism 4. The material conveying system of the concrete mixing plant also includes a lifting drive component 5, which drives the second retractable conveying pipe 12 to extend and retract vertically. The lifting drive component 5 is a power component that drives the second retractable conveying pipe 12 to extend and retract vertically, realizing the vertical height adjustment of the suction end of the conveying pipe. It can adapt to storage silos 400 of different heights to accommodate changes in suction height. For example, if the material on the upper surface has been suctioned out, the suction end of the second retractable conveying pipe 12 can be lowered to suction the material in the lower layer. Furthermore, with the cooperation of the first moving mechanism 3 and the second moving mechanism 4, the material in the storage silo 400 can be suctioned in an all-round and full-coverage manner, improving suction efficiency. The support mechanism 2 can rotate vertically to adjust the horizontal rotation angle of the conveying pipe assembly 1 and expand the coverage area of ​​the suction material. The vertical direction is defined as the Z-axis, with the coordinate system as the reference. It should be noted that in this embodiment, the suction end of the second retractable conveying pipe 12 is the same as the suction end of the conveying pipe assembly 1.

[0141] Specifically, such as Figures 1 to 7 As shown, the material conveying system of the concrete mixing plant in this embodiment uses the conveying pipe assembly 1 as the material conveying channel. The support mechanism 2 provides stable support for the conveying pipe assembly 1 and realizes rotational adjustment. The first moving mechanism 3 and the second moving mechanism 4 cooperate to realize the two-dimensional horizontal movement of the suction end of the conveying pipe assembly 1. The second telescopic conveying pipe 12 and the lifting drive component 5 realize vertical height adjustment, ultimately forming a multi-dimensional adjustment capability of "two-dimensional horizontal movement + vertical lifting + horizontal telescopic movement". It can perform all-round and full-coverage suction of materials in the storage bin 400, improve suction efficiency, and realize accurate, efficient and environmentally friendly conveying of aggregates.

[0142] Specifically, in the material conveying system of the concrete mixing plant in this embodiment, the unloading end of the conveying pipe assembly 1 is placed in the material suction area for suction operation. The power mechanism 100 is started, and a stable negative pressure environment is formed inside the gas-solid separation box 200 and the entire conveying pipe assembly 1 through the air pipe 600. Under the action of negative pressure, the material in the storage bin 400 is sucked into the pipeline from the suction end of the conveying pipe assembly 1. The material is conveyed along the conveying pipe assembly 1 to the gas-solid separation box 200. The dust-laden gas entering the gas-solid separation box 200 is purified, and the purified gas is extracted by the power mechanism 100 through the air pipe 600 and discharged in compliance with standards. The material is deposited at the bottom of the gas-solid separation box 200 under the action of gravity. The first moving mechanism 3 moves horizontally, thereby driving the conveying pipe assembly 1 horizontally. The first telescopic conveying pipe 11 can extend and retract horizontally. When the first moving mechanism 3 moves forward horizontally, the first telescopic conveying pipe 11 also moves forward horizontally, allowing the discharge end of the conveying pipe assembly 1 to suck up material at any position horizontally. Since the support mechanism 2 is rotatable to adjust the horizontal rotation angle of the conveying pipe assembly 1, when the material at the first station has been sucked up horizontally, the second moving mechanism 4 moves along the horizontal longitudinal direction of the moving plate 32 to the second station, simultaneously moving the conveying pipe assembly 1 horizontally to continue sucking up material at the second station. This process is repeated. When the material on the upper horizontal surface has been sucked up, the lifting drive component 5 lowers the suction end of the second telescopic conveying pipe 12 to suck up the lower layer of material until all material is sucked up. Furthermore, with the cooperation of the first moving mechanism 3 and the second moving mechanism 4, the material in the storage bin 400 can be suctioned in an all-round and all-coverage manner, improving suction efficiency. The first moving mechanism 3 and the second moving mechanism 4 work together to realize the two-dimensional horizontal movement of the suction end of the conveying pipe assembly 1, while the second retractable conveying pipe 12 and the lifting drive component 5 realize vertical height adjustment, ultimately forming a multi-dimensional adjustment capability of "two-dimensional horizontal movement + vertical lifting + horizontal extension". This allows for all-round and all-coverage suction of the material in the storage bin 400, improving suction efficiency and achieving precise, efficient, and environmentally friendly conveying of aggregates. It replaces the manual driving and transfer of traditional loaders, avoiding cross-operation between personnel and mobile equipment, and eliminating safety hazards caused by blind spots and center of gravity shifts in loader driving. At the same time, the conveying pipe assembly 1 is a closed structure with no exposed transmission components, avoiding the risk of personnel being drawn in and significantly reducing the accident rate. It also improves environmental protection, as the conveying pipe assembly 1 is a closed channel, and the material is suctioned and unloaded in a closed environment, reducing aggregate spillage and dust generation. In addition, it improves conveying efficiency and reduces space occupancy.

[0143] Optionally, in some embodiments, such as Figures 1 to 7 As shown, the first moving mechanism 3 includes a first driving component 31 and a moving plate 32. The moving plate 32 is movably mounted on the storage bin 400. The first driving component 31 drives the moving plate 32 to move horizontally. The unloading end of the conveying pipe assembly 1 is mounted on the moving plate 32. The first driving component 31 is a driving structure that provides power for the horizontal movement of the moving plate 32. The first driving component 31 drives the moving plate 32 to move horizontally, thereby moving the conveying pipe assembly 1 horizontally and simultaneously moving the first retractable conveying pipe 11 horizontally. The moving plate 32 is a plate-shaped support component that carries the unloading end of the conveying pipe assembly 1, the first motor 311, and the mounting base 42, and is movable horizontally. The horizontal axis is defined as the X-axis.

[0144] Optionally, in some embodiments, such as Figures 1 to 7 As shown, the first drive assembly 31 includes a first motor 311, a first gear 312, and a first rack 313. The first motor 311 is mounted on the moving plate 32, and the first rack 313 is fixedly mounted on the inner wall of the storage bin 400 in a horizontal direction. The first motor 311 is connected to the first gear 312, and the first gear 312 and the first rack 313 mesh with each other. After the first motor 311 starts, it drives the first gear 312 to rotate. Through the meshing transmission between the first gear 312 and the first rack 313, the moving plate 32 is driven to move along the extension direction (horizontal direction) of the first rack 313, thereby driving the conveying pipe assembly 1 to move synchronously, and further driving the first retractable conveying pipe 11 to move horizontally. The gear and rack transmission method has high transmission accuracy and good stability, and can achieve precise positioning of the conveying pipe assembly 1. Compared with hydraulic drive, the response speed is fast and can quickly adapt to different conveying position requirements. The structure is simple and easy to maintain, reducing equipment operation and maintenance costs. The first motor 311 is a geared motor. In other embodiments, the first motor 311 may be replaced by a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0145] Optionally, in some embodiments, such as Figures 1 to 7As shown, the first moving mechanism 3 further includes a first slide rail 33 and a first pulley group 34; wherein the first slide rail 33 and the first pulley group 34 are guide structures used to guide the moving plate 32 to move smoothly in a horizontal direction and reduce moving resistance. The first slide rail 33 is fixedly installed in the storage bin 400 in a horizontal direction, and the first pulley group 34 is disposed below the moving plate 32; the first pulley group 34 and the first slide rail 33 cooperate and slide to form a sliding guide structure to improve moving stability. The cooperation between the first slide rail 33 and the first pulley group 34 reduces friction during the movement process, improves moving efficiency, ensures the smoothness of the movement process, prevents materials from shaking or spilling in the conveying pipe, and restricts the moving direction of the moving plate 32.

[0146] Optionally, in some embodiments, such as Figures 1 to 7 As shown, there are two first slide rails 33, which are arranged opposite each other at an interval, and the movable plate 32 is mounted on the two first slide rails 33; there are two sets of first pulley groups 34, which are respectively arranged below both ends of the movable plate 32. The design of double slide rails and double pulley groups further enhances the load-bearing capacity and the smoothness of movement.

[0147] Optionally, in some embodiments, such as Figures 1 to 7 As shown, the first slide rail 33 is an I-shaped slide rail, and the first pulley group 34 includes at least two first pulleys, which are respectively disposed on the left and right sides of the first slide rail 33. The cooperation between the I-shaped first slide rail 33 and the first pulleys on both sides prevents the moving plate 32 from shifting or falling off during movement, thus improving structural stability.

[0148] Optionally, in some embodiments, such as Figures 1 to 7 As shown, the first retractable conveying pipe 11 includes a horizontal fixed pipe 111 and multiple horizontal telescopic pipes 112. The horizontal fixed pipe 111 is mounted on the support mechanism 2, serving as a basic fixed section. The multiple horizontal telescopic pipes are embedded in the inner wall of the horizontal fixed pipe 111, and are slidably connected to the horizontal fixed pipe 111. The multiple horizontal telescopic pipes are nested and slidably connected to each other. The multi-level nested telescopic pipe structure has high structural stability, is not easily deformed during conveying, and ensures the continuity of material conveying. By extending and retracting the multiple horizontal telescopic pipes 112 in the horizontal direction, the conveying length of the conveying pipe assembly 1 in the horizontal direction is adjusted to adapt to storage bins 400 of different lengths.

[0149] Alternatively, in other embodiments, the first retractable conveying pipe 11 is a corrugated hose 14, utilizing the flexible telescopic characteristics of the corrugated hose 14 to achieve horizontal length adjustment. The corrugated hose 14 possesses certain wear resistance and negative pressure resistance capabilities, making it suitable for aggregate conveying scenarios. The corrugated hose 14 form offers advantages such as simple structure, low cost, and convenient installation.

[0150] Optionally, in some embodiments, such as Figures 1 to 7 As shown, the multi-stage horizontal telescopic tube includes a first horizontal tube 113, a second horizontal tube 114, and a third horizontal tube 115; it adopts a three-level nested structure: the first horizontal tube 113 is embedded in the inner wall of the horizontal fixed tube 111, and the first horizontal tube 113 is slidably connected to the horizontal fixed tube 111; the second horizontal tube 114 is embedded in the inner wall of the first horizontal tube 113, and the second horizontal tube 114 is slidably connected to the first horizontal tube 113; the third horizontal tube 115 is embedded in the inner wall of the second horizontal tube 114, and the third horizontal tube 115 is slidably connected to the second horizontal tube 114, thereby achieving long-distance telescopic adjustment through multi-level nesting.

[0151] Specifically, in this embodiment, such as Figures 1 to 7 As shown, after the first motor 311 starts, it drives the first gear 312 to rotate. Through the meshing transmission between the first gear 312 and the first rack 313, the moving plate 32 is driven to move along the extension direction (horizontal transverse) of the first rack 313, and the first pulley group 34 moves on the first slide rail 33, thereby driving the conveying pipe assembly 1 to move synchronously. The meshing transmission between the first gear 312 and the first rack 313 drives the moving plate 32 to move forward horizontally along the first rack 313. Since the unloading end of the conveying pipe assembly 1 is set on the moving plate 32, the forward movement of the moving plate 32 simultaneously drives the unloading end of the conveying pipe assembly 1 to move forward. The forward movement of the unloading end of the conveying pipe assembly 1 simultaneously pulls out the third horizontal pipe 115, the second horizontal pipe 114, and the first horizontal pipe 113 and moves them forward. At this time, the power of the first motor 311 can realize the extension and retraction of the first horizontal pipe 113, the second horizontal pipe 114, and the third horizontal pipe 115 of the multi-stage horizontal telescopic pipe 112 without the need for additional power components, thus reducing costs.

[0152] Optionally, in some embodiments, such as Figures 1 to 7As shown, the material conveying system of the concrete mixing plant also includes a discharger 500; the batching silo 300 is located below the gas-solid separation box 200; and the discharger 500 is installed on the pipeline between the batching silo 300 and the gas-solid separation box 200. The discharger 500 is a control component for controlling the flow of material from the gas-solid separation box 200 to the batching silo 300. By controlling the discharge process, the discharger 500 closes when the material level in the batching silo 300 reaches the upper limit to prevent overflow; and opens when the material level is below the lower limit to ensure continuous batching. Alternatively, if the gas-solid separation box 200 is full, the discharger 500 is opened to discharge the material from the gas-solid separation box 200 into the batching silo 300. This achieves precise control of the discharge process, improving batching accuracy; and simultaneously prevents negative pressure leakage within the gas-solid separation box 200, ensuring the pressure stability of the entire suction conveying system and improving conveying efficiency. The unloader 500 can be a rotary valve or an electric gate valve, etc.

[0153] Optionally, in some embodiments, such as Figures 1 to 7 As shown, the second moving mechanism 4 includes a second driving component 41 and a mounting base 42. The mounting base 42 is disposed on the moving plate 32 and is slidably connected to the moving plate 32. The second driving component 41 drives the mounting base 42 to move horizontally along the moving plate 32, and the unloading end of the conveying pipe assembly 1 is disposed on the mounting base 42. The second driving component 41 is a driving structure that provides power for the horizontal movement of the mounting base 42. The mounting base 42 is a seat structure that supports the unloading end of the conveying pipe assembly 1 and the second motor 411, and can move horizontally. The second moving mechanism 4 cooperates with the first moving mechanism 3 to realize two-dimensional movement of the conveying pipe assembly 1 in both the horizontal and vertical directions, significantly improving the mobility of the device and the coverage area of ​​the suction material.

[0154] Optionally, in some embodiments, such as Figures 1 to 7As shown, the second drive assembly 41 includes a second motor 411, a second gear 412, and a second rack 413. The second motor 411 is mounted on the mounting base 42, and the second rack 413 is fixedly mounted on the bottom of the moving plate 32 along the horizontal longitudinal direction. The second motor 411 is connected to the second gear 412, and the second gear 412 and the second rack 413 mesh with each other to achieve precise horizontal longitudinal movement of the mounting base 42. When the second motor 411 starts, it drives the second gear 412 to rotate. Through the meshing transmission between the second gear 412 and the second rack 413, the mounting base 42 is driven to move along the extension direction (horizontal longitudinal direction) of the second rack 413, thereby driving the conveying pipe assembly 1 to move synchronously. The second motor 411 is a geared motor. In other embodiments, a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder can be used to replace the second motor 411.

[0155] Optionally, in some embodiments, such as Figures 1 to 7 As shown, the second moving mechanism 4 also includes a second slide rail 43 and a second pulley group 44; the second slide rail 43 and the second pulley group 44 are guide structures used to guide the mounting base 42 to move smoothly along the horizontal longitudinal direction and reduce moving resistance. The second slide rail 43 is arranged at the top of the moving plate 32 along the horizontal longitudinal direction, and the second pulley group 44 is arranged below the mounting base 42; the second pulley group 44 and the second slide rail 43 are slidably connected to each other to improve the smoothness of movement. The second slide rail 43 and the second pulley group 44 provide guidance for the movement of the mounting base 42, limit the movement direction of the mounting base 42, reduce the frictional resistance between the mounting base 42 and the moving plate 32 by the rolling of the pulleys, improve the stability of the mounting base 42 during the movement process, and prevent tipping or deviation; reduce moving resistance, reduce the power consumption of the second motor 411, and improve moving efficiency.

[0156] Optionally, in some embodiments, such as Figures 1 to 7 As shown, there are two second slide rails 43, which are spaced apart and opposite to each other. The mounting base 42 is mounted on the two second slide rails 43. There are two sets of second pulley groups 44, which are respectively arranged below the two sides of the mounting base 42. The design of double slide rails and double pulley groups further enhances the load-bearing capacity and smooth movement. In this embodiment, the second slide rail 43 has the same structure as the first slide rail 33, and the second pulley group 44 has the same structure as the first pulley group 34.

[0157] Optionally, in some embodiments, such as Figures 1 to 7As shown, the support mechanism 2 includes a support base 21 and a support assembly 22; the support base 21 serves to support and fix the material. The support assembly 22 is rotatably mounted on the support base 21 and is rotatably connected to the support base 21 to adjust the horizontal rotation angle of the conveying pipe assembly 1 and expand the coverage area of ​​the suction material. The first retractable conveying pipe 11 is mounted on the support assembly 22. When the first retractable conveying pipe 11 needs to move horizontally, the second moving mechanism 4 drives the first retractable conveying pipe 11 to move horizontally, while the support assembly 22 rotates vertically.

[0158] Optionally, in some embodiments, such as Figures 1 to 7 As shown, the support assembly 22 includes a support column 221, a bearing component 222, and a support frame 223. One end of the support column 221 is rotatably connected to the support base 21 via the bearing component 222, allowing the support column 221 to rotate vertically. The bearing component 222 reduces friction during the rotation of the support column 221, improving rotational flexibility and service life. The rotation of the support column 221 around the support base 21 drives the first retractable conveying pipe 11 to rotate vertically, adjusting the horizontal rotation angle of the conveying pipe assembly 1 and expanding the coverage area for material suction. The other end of the support column 221 is fixedly connected to or integrally formed with the support frame 223. The first retractable conveying pipe 11 is mounted on the support frame 223, which provides stable support for the first retractable conveying pipe 11, preventing deformation or displacement due to gravity and material impact during material conveying, improving the structural stability of the conveying pipe assembly 1, and ensuring the smoothness of the material conveying process.

[0159] Optionally, in some embodiments, such as Figures 1 to 7 As shown, the conveying pipe assembly 1 also includes a bend 13, through which one end of the second retractable conveying pipe 12 is connected to one end of the first retractable conveying pipe 11. The bend 13 is a tubular connector used to connect the first retractable conveying pipe 11 and the second retractable conveying pipe 12, realizing a change in the conveying direction from vertical to horizontal. The bend 13 adopts an arc-shaped tubular structure, with both ends fixedly connected to one end of the first retractable conveying pipe 11 and one end of the second retractable conveying pipe 12, respectively. Its inner wall is smooth to reduce material conveying resistance. The bend 13 is used to realize the switching connection between horizontal and vertical pipelines. By changing the material conveying direction with the bend 13, the material conveyed vertically smoothly transitions to the horizontal conveying direction, avoiding material accumulation and blockage at the change in conveying direction, ensuring the continuity of the conveying process; reducing the impact friction between the material and the inner wall of the pipe, reducing pipe wear, and extending the service life of the equipment.

[0160] Optionally, in some embodiments, such as Figures 1 to 7As shown, the second retractable conveying pipe 12 includes a vertical fixed pipe 121 and a vertical telescopic pipe 122. One end of the vertical fixed pipe 121 is connected to the bent pipe 13, and the vertical telescopic pipe 122 is embedded inside the vertical fixed pipe 121, with the vertical telescopic pipe 122 slidably connected to the vertical fixed pipe 121. The lifting drive component 5 is a lifting cylinder, with one end connected to the vertical fixed pipe 121 and the other end connected to the vertical telescopic pipe 122. The lifting cylinder enables vertical lifting adjustment, and the telescopic movement of the lifting cylinder drives the vertical telescopic pipe 122 to slide within the vertical fixed pipe 121, thereby adjusting the vertical height of the second retractable conveying pipe 12 and ultimately raising or lowering the suction end of the conveying pipe. In other embodiments, the lifting drive component 5 can also be a lifting pneumatic cylinder or a lifting electric cylinder.

[0161] Optionally, in some embodiments, such as Figures 1 to 7 As shown, the conveying pipe assembly 1 also includes a flexible hose 14. One end of the flexible hose 14 is connected to the other end of the first retractable conveying pipe 11, and the other end of the flexible hose 14 is connected to the gas-solid separation box 200, realizing gas-solid separation during material conveying and reducing dust overflow. The flexible hose 14 is a flexible tubular component used to connect the other end of the first retractable conveying pipe 11 to the gas-solid separation box 200 of the concrete mixing plant. The flexible hose 14 is made of wear-resistant and corrosion-resistant flexible material (such as rubber or polyurethane). The flexible hose 14 enables a flexible connection between the first retractable conveying pipe 11 and the gas-solid separation box 200, compensating for slight displacement during the movement of the conveying pipe. The flexible hose 14 is used to adapt to pipeline compensation during rotation or extension, and simultaneously works with the gas-solid separation box 200 to collect dust. The flexible hose 14 enhances the flexibility of the device's movement, avoiding pipe damage caused by rigid connections; and works with the gas-solid separation box 200 to effectively collect dust generated during conveying, reducing dust pollution and improving environmental performance.

[0162] Specifically, such as Figures 1 to 7As shown, in this embodiment of the concrete mixing plant's material conveying system, the unloading end of the conveying pipe assembly 1 is placed in the material suction area for suction operation. The power mechanism 100 is started, and a stable negative pressure environment is formed inside the gas-solid separation box 200 and the entire conveying pipe assembly 1 through the air pipe 600. Under the action of negative pressure, the material in the storage bin 400 is sucked into the pipeline from the suction end of the conveying pipe assembly 1. The material is conveyed along the conveying pipe assembly 1 to the gas-solid separation box 200. The dust-laden gas entering the gas-solid separation box 200 is purified, and the purified gas is extracted by the power mechanism 100 through the air pipe 600 and discharged in compliance with standards. The material is deposited at the bottom of the gas-solid separation box 200 under the action of gravity. The first moving mechanism 3 moves horizontally, and the first motor 311 drives the first gear 312 along the solid-solid separation box 200. The first rack 313 rotates, driving the moving plate 32 to move horizontally along the first slide rail 33. During the movement, the first pulley group 34 slides on both sides of the I-shaped first slide rail 33 to ensure smooth movement. This, in turn, drives the conveying pipe assembly 1 to move horizontally, so that the discharge end of the conveying pipe assembly 1 can suck up materials horizontally. Since the first retractable conveying pipe 11 can extend and retract horizontally, when the first moving mechanism 3 moves forward horizontally, the first retractable conveying pipe 11 also moves forward horizontally at the same time, so that the discharge end of the conveying pipe assembly 1 can suck up materials at any position horizontally. Since the support mechanism 2 is rotatable, the rotation angle of the conveying pipe assembly 1 in the horizontal direction can be adjusted. When the material in the horizontal direction of the first station has been sucked up. At this time, the second moving mechanism 4 moves along the horizontal longitudinal direction of the moving plate 32. The second motor 411 of the second moving mechanism 4 is activated, driving the second gear 412 to rotate along the second rack 413 on the moving plate 32. This causes the mounting base 42 to move horizontally longitudinally along the second slide rail 43 to the second working position. Simultaneously, the unloading end of the conveying pipe assembly 1 moves horizontally longitudinally to the second working position to continue sucking up materials. This process is repeated. When the material on the upper surface in the horizontal direction has been sucked up, the lifting drive component 5 drives the vertical telescopic pipe 122 to extend downward along the vertical fixed pipe 121 to suck up the lower layer of material until all material is sucked up. With the cooperation of the first moving mechanism 3 and the second moving mechanism 4, the material in the storage bin 400 can be sucked up from all directions and with full coverage, improving the suction efficiency. The first moving mechanism 3 and the second moving mechanism 4 work together to achieve two-dimensional horizontal movement of the suction end of the conveying pipe assembly 1. The second retractable conveying pipe 12 and the lifting drive component 5 achieve vertical height adjustment, ultimately forming a multi-dimensional adjustment capability of "two-dimensional horizontal movement + vertical lifting + horizontal extension". This can perform all-round and full-coverage suction of materials in the storage bin 400, improve suction efficiency, and achieve accurate, efficient and environmentally friendly conveying of aggregates.It replaces the manual driving and transportation of traditional loaders, avoids cross-operation between personnel and mobile equipment, and eliminates safety hazards caused by blind spots and center of gravity shift of loaders. At the same time, the conveying pipe assembly 1 is a closed structure with no exposed transmission components, avoiding the risk of personnel being drawn in and significantly reducing the accident rate. It also improves environmental protection, as the conveying pipe assembly 1 is a closed channel where materials are sucked and unloaded in a closed environment, reducing aggregate spillage and dust generation. Furthermore, it improves conveying efficiency and reduces space occupancy.

[0163] Furthermore, during the conveying process, if the material in the storage bin 400 decreases locally, the suction end can be moved in a horizontal two-dimensional direction by the first moving mechanism 3 and the second moving mechanism 4, and the suction position can be adjusted by the rotation of the support mechanism 2 and the extension and retraction of the first telescopic conveying pipe 11 to ensure continuous suction. If the material level in the batching bin 300 reaches the preset upper limit, the unloader 500 and the power mechanism 100 are shut down to stop the conveying. If the material level is lower than the preset lower limit, the equipment is restarted to resume conveying.

[0164] After the conveying task is completed, the power mechanism 100 and the unloader 500 are shut down. The suction end and conveying pipe assembly 1 are then reset to their initial positions via the various drive components, facilitating subsequent operations or equipment maintenance. The entire working process achieves automated, closed, and precise material conveying, effectively solving the shortcomings of existing technologies and ensuring continuous and stable operation of the mixing plant.

[0165] The advantages of the above technical solution, which differ from existing technologies, are as follows:

[0166] Improve production safety: The first moving mechanism 3, the second moving mechanism 4 and the lifting drive component 5 realize the automation of the conveying process, replace the manual transfer of the loader, avoid the cross-operation of personnel and mobile equipment, and eliminate the safety hazards caused by the blind spot and center of gravity shift of the loader. At the same time, the conveying pipe assembly 1 is a closed structure with no exposed transmission components, avoiding the risk of personnel being drawn in and greatly reducing the accident rate.

[0167] Improved conveying efficiency: Automated conveying replaces manual operation. The continuous conveying channel of the first retractable conveying pipe 11, combined with multi-dimensional adjustment capabilities, eliminates back-and-forth waiting time. Compared to belt conveyors, it has a faster start-stop response and can precisely match the continuous production needs of large-scale mixing plants, avoiding material shortages in the batching silo 300. It forms a multi-dimensional adjustment capability of "horizontal two-dimensional movement + vertical lifting + horizontal extension," enabling all-round, full-coverage suction of materials within the storage silo 400, improving suction efficiency and achieving precise, efficient, and environmentally friendly aggregate conveying.

[0168] Improved environmental performance: The conveying pipe assembly 1 is a closed channel, allowing materials to be drawn in and unloaded within a closed environment, reducing aggregate spillage and dust generation. Simultaneously, connected to the gas-solid separation box 200 via the flexible hose 14, it can centrally treat the small amount of dust generated during conveying, reducing dust concentration in the work area, improving environmental friendliness, and reducing the cost of cleaning up spilled aggregate. The gas-solid separation box 200 purifies the dust-laden gas, ensuring that the purified gas meets emission standards, solving the dust pollution problem in existing technologies; no additional manpower is required to clean up spilled aggregate, reducing operating costs.

[0169] Reduced space occupancy: The first moving mechanism 3 and the second moving mechanism 4 are compact structures, eliminating the need to reserve space for the loader to travel and turn; the conveying pipe assembly 1 is telescopic and adjustable, eliminating the need for fixed long-distance layout space, greatly improving the flexibility of the overall layout of the mixing plant, and making it suitable for small mixing plants or renovation and expansion projects with limited site space.
