Description

Technical Field

[0001] This invention relates to the field of intelligent warehousing technology, and in particular to an automated production line and method for storing granular materials. Background Technology

[0002] In industrial and agricultural production, the transportation, storage, processing, mixing, and stirring of granular materials are widespread, including grains, coal, slag, sand, gravel, and plastics. Currently, most operations throughout the transportation and storage process rely on traditional loaders for loading and unloading. However, traditional loader loading and unloading is entirely manual, and the repetitive nature of manual operations easily leads to worker fatigue. Especially during the process of transporting granular materials to storage, loaders are needed in conjunction with transport vehicles to pile the materials in the storage area. This results in a scenario where transport vehicles and loaders work alternately, which easily leads to vehicle collisions and safety accidents. Furthermore, the back-and-forth movement of transport vehicles and loaders within the storage area hinders the installation of automated granular material output equipment. The continuous loading and unloading of transport vehicles and the constant piling of granular materials by loaders also incurs significant fuel consumption and labor costs. Most traditional loaders currently in use are powered by diesel fuel, and the piling process generates a large amount of exhaust gas that pollutes the environment, especially during the piling of grain, potentially causing serious contamination.

[0003] Currently, there are no mature complete sets of dumping conveyors on the market that can achieve automated warehousing of granular materials. Summary of the Invention

[0004] The purpose of this invention is to address the existing problems in the warehousing of granular materials, which are mostly handled by traditional loaders. The alternating operation of transport vehicles and loaders can easily lead to accidents.

It can be combined into enclosed silos, reducing the need for loaders and transport vehicles to perform piling operations in the storage area, thus avoiding safety accidents such as vehicle collisions. The absence of loaders and transport vehicles in the silo area reduces fuel consumption and labor input, lowers construction costs, and prevents pellet material contamination.

[0027] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0028] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0029] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but that it can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0030] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0031] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as 2, 3, 4, 5, 6, 7, 8, or 9, and can even exceed nine.

[0032] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0033] In related technologies, traditional loaders are used for loading and unloading in most situations throughout the transportation or storage process. Traditional loader loading and unloading relies entirely on manual operation, and the repetitive nature of manual labor easily leads to worker fatigue. Especially during the process of transporting granular materials to storage, loaders are needed in conjunction with transport vehicles to pile up the granular materials in the storage area. This results in a scenario where transport vehicles and loaders work alternately, which easily leads to vehicle collisions and safety accidents. Furthermore, the back-and-forth movement of transport vehicles and loaders within the storage area hinders the installation of automated granular material output equipment. The continuous loading and unloading of transport vehicles and the constant piling of granular materials by loaders also incurs significant fuel consumption and labor costs. Currently, most traditional loaders are powered by diesel fuel, and the piling operation generates a large amount of exhaust gas that pollutes the environment. Therefore, the technical solution of this application was developed, which is described below in conjunction with… Figures 1 to 3 To elaborate.

[0034] Example 1

[0035] like Figures 1 to 3 As shown in the figure, the automated warehousing production line for granular materials of the present invention includes unloading equipment 1, main belt conveyor system, arrow-shaped material distribution device 4, distribution belt conveyor system, video recognition system and PLC control center.

[0036] The unloading equipment 1 is installed outside the silo site. Depending on the terrain around the silo site, if there are high and low platforms and the terrain is suitable for unloading vehicles, the unloading equipment 1 can be installed directly on the ground. If there are no high and low platforms and no flat site suitable for unloading vehicles, a sunken unloading equipment 1 needs to be installed. The unloading equipment 1 is used to receive external granular materials.

[0037] like Figure 1 and Figure 2As shown, the unloading device 1 includes a hopper support frame, a hopper, a discharge port, and a chain conveyor. The hopper is installed on the upper end of the hopper support frame, and the chain conveyor is installed on the lower end of the hopper support frame. The discharge port is located at one end of the chain conveyor. The chain conveyor consists of multiple sets of scraping chain plates. A driven gear for the scraping chain plate is located at one end, and a driving gear for the scraping chain plate is located at the other end. A high-power geared motor is configured on the driving gear. The discharge port is connected to the main belt conveyor system.

[0038] like Figure 1 and Figure 2 As shown, the main belt conveyor system includes a belt conveyor support frame, a climbing belt conveyor 2, and a horizontal belt conveyor 3. Several silo partitions 6 are spaced apart in the granular silo to form different silos for storing granular materials of different sizes. The belt conveyor support frame is erected on one side of the unloading device 1 and on the upper end of the silo partition 6. The climbing belt conveyor 2 and the horizontal belt conveyor 3 are respectively installed on the belt conveyor support frame. Optionally, the horizontal belt conveyor 3 is arranged perpendicular to the silo partition 6 in the horizontal plane. The climbing belt conveyor 2 is equipped with a toothed belt, and both the climbing belt conveyor 2 and the horizontal belt conveyor 3 are equipped with high-power geared motors. A climbing belt conveyor 2 is installed at the discharge port of the unloading device 1, a receiving hopper is installed at the output end of the climbing belt conveyor 2, and a horizontal belt conveyor 3 is installed at the lower end of the receiving hopper; a plurality of arrow-shaped material distribution devices 4 are arranged at intervals on the horizontal belt conveyor 3, and left and right material distribution hoppers are respectively installed at the tail ends of the arrow-shaped material distribution devices 4.

[0039] like Figure 1 and Figure 2As shown, the belt conveyor system includes multiple belt conveyors 5, belt guide rails 8, and belt support frames 7. Each belt conveyor 5 is a bidirectional conveyor belt. One belt conveyor 5 is correspondingly installed at the lower end of the hopper. The belt conveyors 5 are mounted overhead on the upper end of the hopper partition wall 6 via the belt support frames 7. Optionally, multiple belt support frames 7 are erected perpendicular to the hopper partition wall 6 in a horizontal plane, with the belt support frames 7 spaced apart along the length of the hopper partition wall 6. Multiple belt guide rails 8 are erected perpendicular to the belt support frames 7 in a horizontal plane. The belt conveyor 8 is arranged parallel to the silo partition wall 6 and perpendicular to the horizontal belt conveyor 3; the belt conveyor 5 is arranged along the length of the belt conveyor 8, and multiple sets of pulleys are arranged at the bottom of the belt conveyor 5. A drive wheel and a reduction motor are arranged at one end of the belt conveyor 5; power is drawn from the drive wheel of the belt conveyor 5 to drive the multiple sets of pulleys at the bottom of the belt conveyor 5 to move along the belt conveyor 8; when the drive wheel of the belt conveyor 5 turns to the right, the multiple sets of pulleys at the bottom of the belt conveyor 5 slide to the left, so that the granular material is layered and piled up from right to left.

[0040] like Figure 1 and Figure 2 As shown, the arrow-shaped material distribution device 4 includes a material distribution support frame, a material distribution roller, an arrow-shaped material distribution plate, an arrow plate control cylinder, and a cylinder control motor. The material distribution roller is installed at the lower end of the material distribution support frame, the cylinder control motor is installed at the upper end of the material distribution support frame, the arrow plate control cylinder is installed at the front end of the cylinder control motor, and the arrow-shaped material distribution plate is installed at the front end of the arrow plate control cylinder. The arrow-shaped material distribution plate includes a rigid plate and a flexible plate. The rigid plate is perpendicular to the horizontal belt surface of the horizontal belt conveyor 3 at a 90-degree angle, and the flexible plate is at an obtuse angle of not less than 110 degrees and not more than 160 degrees with the horizontal belt surface of the horizontal belt conveyor 3 to facilitate the scraping of granular material. The flexible plate is installed on the surface of the rigid plate and is located below the rigid plate.

[0041] The arrow-shaped material distribution plate control cylinder can drive the arrow-shaped material distribution plate to move closer to or away from the horizontal belt surface of the horizontal belt conveyor 3. After approaching, the bottom of the flexible plate contacts the horizontal belt surface of the horizontal belt conveyor 3. The function of the material distribution roller is to lift the corresponding horizontal belt surface of the horizontal belt conveyor 3 when the arrow-shaped material distribution plate approaches the horizontal belt surface of the horizontal belt conveyor 3. Even when the arrow-shaped material distribution plate and the horizontal belt surface of the horizontal belt conveyor 3 are close to each other, the material distribution roller is connected to the arrow-shaped material distribution plate control cylinder through a transmission assembly. That is, the arrow-shaped material distribution plate control cylinder simultaneously drives the arrow-shaped material distribution plate and the horizontal belt surface of the horizontal belt conveyor 3 to move closer to or away from each other. The transmission assembly may include a parallel four-bar linkage mechanism. The flexible plate is made of rubber, and the rigid plate is made of steel. The rigid plate is used to constrain the flexible plate to maintain its arrow shape. After the arrow-shaped material distribution plate approaches and contacts the horizontal belt surface of the horizontal belt conveyor 3 (i.e., the arrow-shaped material distribution device 4 is closed relative to the horizontal belt conveyor 3), it can scrape off the granular material transported by the horizontal belt surface of the horizontal belt conveyor 3 and distribute it through the material distribution hopper to the corresponding material distribution conveyor 5, and then the material distribution conveyor 5 transports it to the stacking position of the corresponding silo. If the granular material transported by the horizontal belt surface of the horizontal belt conveyor 3 is not the material to be stacked in this silo, the arrow plate control cylinder corresponding to this silo can drive the arrow-shaped material distribution plate away from the horizontal belt surface of the horizontal belt conveyor 3 (i.e., the arrow-shaped material distribution device 4 is open relative to the horizontal belt conveyor 3), and the granular material continues to be transported by the horizontal belt surface of the horizontal belt conveyor 3.

[0042] like Figure 3 As shown, the video recognition system includes a high-definition camera, a display screen, a first switch, and a network cable; the high-definition camera is installed at the unloading hopper and the discharge port of the unloading device 1, at the arrow-shaped material distribution plate of the arrow-shaped material distribution device 4, and at the end of each of the belt conveyors 5 in the belt conveyor system, and is connected to the display screen through the first switch and the network cable.

[0043] like Figure 3As shown, the PLC control center includes a computer and a second switch. The computer includes a monitor, input keyboard, and mouse. The computer is connected to the control power supply of the high-power geared motor on the drive gear of the chain conveyor, the control power supply of the high-power geared motors of the climbing belt conveyor 2 and the horizontal belt conveyor 3, the control power supply of the hydraulic cylinder control motor on each arrow-shaped material distribution device 4, and the control power supply of the geared motor of each belt conveyor 5, through the second switch. According to the need to convey different granular materials, the arrow-shaped material distribution plate on the single arrow-shaped material distribution device 4 corresponding to the hopper is closed in real time, and the arrow-shaped material distribution plates of the other multiple arrow-shaped material distribution devices 4 and the corresponding geared motors of the belt conveyors 5 are opened.

[0044] The computer is connected to the video recognition system through the second switch. The PLC control center controls the unloading equipment 1, the main belt conveyor system, the arrow-shaped material sorting device 4, and the branch belt conveyor system according to the real-time images provided by the video recognition system to realize the automated classification and storage of granular materials according to their gradation.

[0045] This embodiment describes an automated pellet material silo production line. It utilizes the unloading device 1 to unload incoming pellet materials and transports them via belt conveyor, eliminating the need for traditional loader transport. The arrow-shaped material distribution device 4 switches the pellet materials transported by the main belt conveyor system to the distribution belt conveyor system for delivery to the corresponding silos. This achieves fully automated, unmanned unloading of various pellet materials, and eliminates the need for additional silo equipment within the silo area, providing favorable conditions for the installation of automated output equipment. It can be combined into enclosed silos, reducing the need for loaders and transport vehicles to perform piling operations in the storage area and preventing collisions. The absence of loaders and transport vehicles in the silo area reduces fuel consumption and labor input, lowers construction costs, and avoids pellet material contamination. This automated pellet material silo production line has a simple structure, is easy to use, and performs well.

[0046] Example 2

[0047] like Figures 1 to 3 As shown in the figure, the automated warehousing method for granular materials of the present invention utilizes the automated warehousing production line for granular materials as described in Example 1. The method includes the following steps:

[0048] Foreign granular material is placed into the unloading equipment 1, and the foreign granular material is identified by the video recognition system. The storage bin of the foreign granular material is determined and set as the target bin.

[0049] The control center starts the belt conveyor system and the arrow-shaped material distribution device 4 corresponding to the target silo, as well as the unloading equipment 1 and the main belt conveyor system. The arrow-shaped material distribution device 4 is close to and attached to the main belt conveyor system. The incoming granular material is transported by the unloading equipment 1 and the main belt conveyor system, scraped off by the arrow-shaped material distribution device 4 and sent to the belt conveyor system, and then transported to the corresponding silo by the belt conveyor system.

[0050] The automated warehousing method for granular materials described in this embodiment, through the coordinated operation of the video recognition system and the control center, can activate the equipment corresponding to the transportation of this batch of granular materials to transport the granular materials to the corresponding silos, thereby enhancing the automated warehousing capability of granular materials.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
