Description

Technical Field

[0001] This invention relates to the field of material storage technology, and in particular to a silo device. Background Technology

[0002] In food processing, materials such as vegetable leaves are stored in specialized silos and then dispensed as needed. Because vegetable leaves contain a certain amount of moisture and have a relatively large volume, they easily stick together and tangle, resulting in poor flowability. This can cause bridging at the discharging end of the silo, leading to blockages. Therefore, common discharging mechanisms that rely solely on the weight of the material (such as opening and closing gates) are unsuitable. For these reasons, there is an urgent need for a silo device suitable for materials such as vegetable leaves, capable of preventing blockages and ensuring normal discharging.

[0024] In food processing, materials such as vegetable leaves are stored in specialized silos and then dispensed as needed. Because vegetable leaves contain a certain amount of moisture and have a relatively large volume, they easily stick together and tangle, resulting in poor flowability. This can cause bridging at the discharging end of the silo, leading to blockages. Therefore, common discharging mechanisms that rely solely on the weight of the material (such as opening and closing gates) are unsuitable. For these reasons, there is an urgent need for a silo device suitable for materials such as vegetable leaves, capable of preventing blockages and ensuring normal discharging.

[0025] To address the aforementioned technical problems, this invention proposes a silo device.

[0026] Please see Figures 1 to 3 In one embodiment of the present invention, the silo device includes: The silo body 10 is used for storing materials; The feeding mechanism 20 is located at the feeding end of the hopper body 10. The feeding mechanism 20 includes two feeding rollers 30 arranged in parallel to each other, and a feeding channel 21 for material to pass through is left between the two feeding rollers 30. The circumferential surface of the feeding rollers 30 is provided with a number of protruding structures 40. The rotary drive mechanism 50 is used to drive the two feeding rollers 30 to rotate in opposite directions. Understandably, as shown in the figure, the left feeding roller 30 rotates clockwise and the right feeding roller 30 rotates counterclockwise, so that the material is fed along the feeding channel 21 under the drive of the protruding structure 40. The control module 60 is electrically connected to the rotary drive mechanism 50.

[0027] The technical solution of this invention utilizes two feeding rollers 30 with raised structures 40 on their surfaces that can rotate in opposite directions to form a forced mechanical feeding structure. The raised structures 40 enhance the gripping and pushing force on the material, discharging it along the feeding channel 21 from the feeding end of the hopper body 10 for feeding operations. This overcomes the bridging pattern that easily forms when feeding by its own weight, which leads to the risk of material blockage in the prior art. This design transforms passive feeding into active gripping feeding, significantly improving the feeding reliability of materials with large individual volumes that are prone to sticking and tangling. This enables a hopper device suitable for materials such as vegetable leaves, preventing material blockage and allowing for normal feeding operations. Simultaneously, the control module 60 precisely regulates the rotation speed of the rotary drive mechanism 50, supporting multi-material adaptation and personalized speed adjustment, covering the material storage and feeding needs of different industries.

[0028] Understandably, when no feeding operation is required, the feeding roller 30 stops rotating. At this time, the feeding channel 21 is blocked by the protruding structures 40 of the two feeding rollers 30, preventing material from being discharged from the feeding channel 21, thus avoiding material being discharged from the feeding channel 21 during non-feeding times. In other embodiments, an opening and closing gate is provided below the feeding mechanism 20. The opening and closing gate is linked with the rotary drive mechanism 50. That is, when the rotary drive mechanism 50 rotates to drive the feeding roller 30 to rotate for feeding operation, the opening and closing gate switches to the open state so that the material passes through the feeding channel 21 and the opening and closing gate in sequence for feeding; when the rotary drive mechanism 50 stops driving the feeding roller 30 to rotate, the opening and closing gate switches to the closed state to prevent some material from passing through the obstruction of the protruding structures 40 in the feeding channel 21 and being discharged on its own, affecting the feeding accuracy.

[0029] As a preferred embodiment of the above embodiments, refer to Figure 1 The rotary drive mechanism 50 includes two drive motors 51, each corresponding to a feeding roller 30. This configuration, by adopting an independent drive mode for the two drive motors 51, enables precise and independent control of the rotational speed and torque of the two feeding rollers 30, avoiding the synchronization errors and power losses that may occur with mechanical transmission of a single motor. This ensures that the material in the feeding channel 21 is subjected to uniform force and the conveying is more stable.

[0030] As a preferred embodiment of the above, the hopper body 10 and / or the feeding mechanism 20 are provided with a wear-resistant protective layer (not shown in the attached drawings) on the side that comes into contact with the material. This arrangement, with the wear-resistant protective layer on the contact surface, directly addresses the wear caused by moisture, acidic substances, or fibers that may be present in materials such as vegetable leaves, significantly improving the durability and corrosion resistance of key components of the hopper device and extending the overall service life of the hopper device.

[0031] As a preferred embodiment of the above embodiments, refer to Figures 4 to 5The feeding roller 30 includes a roller body 31 and a cylindrical protrusion structure 40. The protrusion structure 40 includes several first protrusions 41 and several second protrusions 42. The first protrusions 41 are fixedly mounted on the roller body 31, and the second protrusions 42 are retractably mounted on the roller body 31. The roller body 31 has an adjustment cavity 32 and an adjustment mechanism 33 installed in the adjustment cavity 32. The adjustment mechanism 33 is used to adjust the extension and retraction state of the second protrusions 42. The adjustment mechanism 33 is electrically connected to the control module 60. With this configuration, by designing the protrusion structure 40 of the feeding roller 30 to be composed of fixed first protrusions 41 and retractable second protrusions 42, and integrating the adjustment mechanism 33 driven by the control module 60 inside the roller body 31, this structure achieves active dynamic control of the gripping shape of the roller surface. When processing tough, tightly tangled vegetable leaves, the second protrusion 42 can be extended to form a dense gripping array with the fixed protrusion, enhancing tearing and pushing capabilities. Conversely, when processing delicate and fragile vegetable leaves, the second protrusion 42 can be retracted, with only the first protrusion 41 providing adequate gripping force, preventing excessive puncture and material breakage. This design allows the feeding mechanism 20 to intelligently adapt to different types of vegetable leaves with varying moisture contents or processing requirements, ensuring feeding efficiency while maintaining material integrity, significantly improving the equipment's versatility and process adaptability.

[0032] Specifically, the adjustment mechanism 33 includes an adjustment drive device 34 and an adjustment rod 35, which is coaxially arranged with the roller body 31. The adjustment drive device 34 drives the adjustment rod 35 to slide along its axial direction. The side of the adjustment rod 35 is provided with a plurality of adjustment grooves 36, which correspond one-to-one with the second protrusions 42. The first end of the second protrusion 42 is slidably connected in the adjustment groove 36. The bottom of the adjustment groove 36 is provided with an inner concave region 361 and an outer convex region 362. When the first end of the second protrusion 42 slides to the inner concave region 361, the second end of the second protrusion 42 retracts into the roller body 31. When the first end of the second protrusion 42 slides to the outer convex region 362, the second end of the second protrusion 42 extends out of the roller body 31. With this configuration, the adjustment mechanism 33, through the coaxially arranged adjustment rod 35 and the adjustment grooves 36 with special contours on their surfaces, accurately converts the axial linear motion into the radial extension and retraction of the protrusions. Specifically, when the adjustment drive device 34 pushes the adjustment rod 35 to slide axially along the roller body 31, the first end of each second protrusion 42 is forced to move along its contour trajectory within the corresponding adjustment groove 36. When its first end slides to the concave area 361 of the adjustment groove 36, the second protrusion 42 gains inward movement space, causing its second end to retract into the roller body 31 to form a gentle gripping mode. When its first end slides to the convex area 362 of the adjustment groove 36, the contour of the adjustment groove 36 pushes the second protrusion 42 outward, causing its second end to extend out of the roller body 31 surface to form a strong gripping mode. This purely mechanical linkage design utilizes simple axial displacement to synchronously control the unified state switching of all second protrusions 42, achieving a reliable, precise, and maintenance-free gripping intensity adjustment function. In this embodiment, the adjustment drive device 34 is configured as a telescopic motor.

[0033] Furthermore, the concave region 361 and the convex region 362 are connected by a guide ramp 363. This configuration allows the guide ramp 363 to serve as a transition structure between the concave and convex regions 361, and its inclined surface provides a continuous and smooth path for the first end of the second protrusion 42 to move between them. When the adjusting rod 35 slides axially, the first end of the second protrusion 42 gradually rises or falls along the guide ramp 363, allowing the extension and retraction of the second protrusion 42 to be completed smoothly and gradually, thereby ensuring the stability and mechanical reliability of the switching process of the second protrusion 42's working state.

[0034] Furthermore, the side of the roller body 31 is provided with several sliding channels 37, each corresponding to a second protrusion 42. The middle part of the second protrusion 42 is slidably connected to the sliding channel 37. A cavity 38 is provided in the sliding channel 37. An adjusting ring 43 and an elastic member 44 are fixedly provided in the middle of the second protrusion 42. The adjusting ring 43 is slidably connected to the cavity 38 along with the second protrusion 42. The two ends of the elastic member 44 abut against the adjusting ring 43 and the inner wall of the cavity 38, respectively. The elastic member 44 is used to apply an elastic force to the second protrusion 42 toward the adjusting groove 36. With this configuration, the combined structure of the sliding channel 37 and the elastic member 44 provides a comprehensive function of guiding, resetting, and buffering for the extension and retraction movement of the second protrusion 42. The sliding channel 37 precisely guides the second protrusion 42 to move along a radial trajectory; the cavity 38 inside it accommodates the middle part of the second protrusion 42 with the adjustment ring 43, and the elastic member 44 (such as a compression spring) continuously applies elastic pressure toward the adjustment groove 36 to the adjustment ring 43, ensuring that the first end of the second protrusion 42 is always in close contact with the contour of the adjustment groove 36, thereby eliminating movement gaps and improving response accuracy.

[0035] As a preferred embodiment of the above embodiments, refer to Figure 7 The hopper device includes a vibration mechanism 70, which is located on the side of the hopper body 10. The vibration mechanism 70 drives the hopper body 10 to vibrate. The vibration mechanism 70 is electrically connected to the control module 60. This configuration, by adding the vibration mechanism 70 integrated with the side of the hopper body 10, allows for the application of periodic vibration force to the entire material inside. This vibration effectively breaks down the adhesion and early bridging tendencies between materials far from the feeding roller 30, causing the material to loosen and fluidize in advance. This creates better feeding conditions for the feeding roller 30 to grasp the material, forming a collaborative anti-blocking mechanism of "overall pre-loosening + local grasping," further improving the smoothness and continuity of material feeding from the source.

[0036] As a preferred embodiment of the above embodiments, refer to Figure 7 The hopper device includes a receiving mechanism 80, which comprises a receiving plate (not shown in the attached diagram) and a weighing sensor (not shown in the attached diagram). The receiving plate is located directly below the discharge end of the hopper body 10, and the weighing sensor is installed at the bottom of the receiving plate. The weighing sensor is electrically connected to the control module 60. This configuration, by integrating the receiving mechanism 80 containing the weighing sensor, enables real-time and accurate metering during the discharge process. The control module 60 can dynamically adjust the rotation speed of the discharge roller 30 based on the weighing data feedback, achieving quantitative and constant-speed discharge. This meets the high requirements for ingredient accuracy and batch consistency in food processing, upgrading the discharge device from a simple conveying tool to a metering and feeding system with closed-loop control capabilities.

[0037] As a preferred embodiment of the above embodiments, refer to Figure 7 The silo device includes a temperature and humidity adaptation mechanism 90, which is located inside the silo body 10. The temperature and humidity adaptation mechanism 90 is used to acquire the internal temperature and humidity of the silo body 10 and adjust it to a preset range. This configuration allows for proactive monitoring and adjustment of the internal environment of the silo body 10. Maintaining stable temperature and humidity within a suitable range prevents materials such as vegetable leaves from wilting and sticking due to excessive dryness, or from spoiling due to excessive humidity. This ensures material quality while maintaining relative stability of material properties, making the feeding process more controllable and improving system stability and material preservation capabilities from an environmental perspective.

[0038] As a preferred embodiment of the above embodiments, refer to Figure 7 The hopper device includes an alarm mechanism 100, which comprises an audible and visual alarm device (not shown in the attached diagram) and a remote alarm device (not shown in the attached diagram). The alarm mechanism 100 is electrically connected to the control module 60. This configuration allows the control module 60 to collect real-time operating status data from each unit mechanism (rotary drive mechanism 50, feeding mechanism 20, vibration mechanism 70, and heat dissipation mechanism 110, etc.) and link it with the feeding mechanism 20 to achieve tiered anomaly handling, avoiding production interruptions caused by a single shutdown alarm, and improving fault handling efficiency and emergency response capabilities. For example, if the fault diagnosis unit of the control module 60 determines that there is a blockage fault based on changes in the load of the drive motor 51 and a sudden drop in the feeding speed, it will drive the feeding roller 30 to run in reverse for a short time and drive the vibration mechanism 70 to vibrate at high frequency to try to clear the blockage. If clearing fails, it will trigger the audible and visual alarm device and send a remote notification to the staff's mobile phone software using the remote alarm device. The notification will display "Please handle the blockage". If the weighing sensor has no data feedback or the data is abnormal, indicating a weighing fault, the control module 60 will switch to the preset speed feeding mode to maintain production continuity. The alarm mechanism 100 will prompt "Weighing abnormal, preset speed feeding mode has been switched". The log recording module will store the fault information for subsequent calibration. If the rotation drive mechanism 50 is detected to be overheating, indicating a equipment fault, the control module 60 will reduce the speed of the drive motor 51 or temporarily stop the machine. The alarm mechanism 100 will issue an alarm signal and trigger the heat dissipation mechanism 110 to run. After the fault is cleared, normal operation will automatically resume.

[0039] As a preferred embodiment of the above embodiments, refer to Figure 7The hopper device includes a heat dissipation mechanism 110, which is used to dissipate heat from the rotary drive mechanism 50. The heat dissipation mechanism 110 is electrically connected to the control module 60. With this configuration, the added heat dissipation mechanism 110 can effectively manage the operating temperature of heat sources such as the drive motor 51, preventing overheating and efficiency degradation or damage caused by long-term high-load operation, thereby ensuring the long-term reliable operation of the core power components in continuous production scenarios.

[0040] As a preferred embodiment of the above embodiments, refer to Figure 6 The hopper device is externally enclosed in a dustproof and sealed housing 120. This design prevents industrial dust from entering the drive motor 51 and sensor interface, thus avoiding component jamming or malfunction.

[0041] As a preferred embodiment of the above embodiments, refer to Figure 6 The silo device includes several silo bodies 10 arranged in a linear array. This arrangement, using a linear array of multiple silo bodies 10, achieves modularity and integration, facilitating the separate storage of different materials, formula feeding, or large-scale parallel processing, significantly improving the system's layout flexibility and overall processing capacity in complex production lines.

[0042] It should be noted that other aspects of the silo device disclosed in this invention are prior art and will not be described in detail here.

[0043] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. Any application of the present invention directly or indirectly in other related technical fields is included within the patent protection scope of the present invention.
