Description

Technical Field

[0001] This utility model relates to the field of material storage technology, and in particular to a material storage discharge control mechanism. Background Technology

[0002] In the field of material storage, the design of the discharge control mechanism is crucial, as it directly affects the efficiency and stability of the storage system.

[0003] The material is stored in the hopper body, awaiting a discharge command. When the discharge command is issued, the material is discharged through the discharge port. During this process, if the discharge mechanism is not controlled in a timely manner, the actual discharge volume may deviate from the expected discharge volume. Furthermore, due to the material's viscosity, moisture content, particle size, or shape, its flowability may be poor. Therefore, for the same weight of material, the discharge mechanism may need a longer time to open the discharge channel to ensure smooth material flow. Utility Model Content

[0004] The purpose of this invention is to provide a material storage and discharge control mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A material storage discharge control mechanism includes: a hopper, a discharge port provided below the hopper, a movable plug provided on the inner wall of the discharge port, a connecting rod fixedly provided on the movable plug, a pulling component for pulling the movable plug up and down provided on the connecting rod, and reset components for resetting at both ends of the pulling component.

[0007] Preferably, the bottom of the hopper is inclined, and the inclination angle of the discharge port is greater than the inclination angle of the movable plug.

[0008] Preferably, the pulling component includes a fixing seat, which is disposed on the inner wall of the hopper.

[0009] Preferably, a rotating shaft is provided through the fixed base, and a rotating rod is rotatably connected to the rotating shaft.

[0010] Preferably, the middle part of the rotating rod is rotatably connected to the connecting rod via a connecting pin.

[0011] Preferably, a through groove is provided through the rotating rod, a hook is provided in the through groove, a movable pull rod is provided on the hook, and a movable plate is fixedly provided on the pull rod.

[0012] Preferably, the reset assembly includes a retaining shaft, which is respectively disposed on the fixed base and the rotating rod, and a tension spring is engaged on the two retaining shafts.

[0013] Preferably, the reset assembly further includes a second fixing seat, which is disposed on the inner wall of the hopper opposite to the first fixing seat.

[0014] Preferably, the fixed base 2 and the vertical section of the rotating rod are respectively provided with a retaining shaft 2, and several retaining shaft 2 arrays are distributed on the vertical section of the rotating rod.

[0015] Preferably, a tension spring is engaged with one of the two retaining pins on the fixed base and one of the retaining pins on the vertical section of the rotating rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The opening and closing of the discharge port is controlled by a pulling component. The coordinated action of the movable plug, connecting rod, pulling component, and reset component enables precise control of material discharge. This mechanism features simple structure, convenient operation, and high reliability, making it suitable for various material storage and conveying systems.

[0018] By setting the discharge port's tilt angle to be greater than that of the movable plug, it is ensured that material flows out of the discharge port quickly and in a concentrated manner when the movable plug opens, reducing the risk of material residue and blockage. The tilt angle design takes into account the material's flowability, allowing the material to form a stable flow layer within the hopper. This design helps prevent the formation of dead zones or accumulation of material within the hopper, thereby improving material utilization and conveying efficiency.

[0019] The discharge rate is adjusted by regulating the distance between the hook and the rod. Different materials have different flowability and particle size distribution. Therefore, when adjusting the distance, the characteristics of the material must be fully considered to ensure the stability and efficiency of the discharge process. The distance between the hook and the rod can be flexibly adjusted according to the conveying requirements and flow rate of the production line to achieve the best discharge effect.

[0020] By placing tension springs one and two at both ends of the rotating rod, a uniform force is provided to the rotating rod to reset the movable plug at the bottom of the connecting rod. This ensures that the tension at both ends is uniform and equal when the rotating rod rotates. This design helps reduce deflection and twisting of the rotating rod during rotation, thereby improving its stability and durability. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0028] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0029] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0030] Please see Figures 1-3A material storage discharge control mechanism includes: a hopper 1, which is the main container for storing materials. A discharge port 2 is located below the hopper 1, serving as the channel for material outflow. A movable plug 3 is installed on the inner wall of the discharge port 2, and its up-and-down movement controls the opening and closing of the discharge port 2. The movable plug 3 fits tightly against the inner wall of the discharge port 2 to prevent material leakage. A connecting rod 7 is fixedly mounted on the movable plug 3, connecting it to a pulling assembly. A pulling assembly for pulling the movable plug 3 up and down is mounted on the connecting rod 7, and reset assemblies are located at both ends of the pulling assembly for resetting. This material storage discharge control mechanism achieves precise control of material discharge through the coordinated action of the movable plug 3, connecting rod 7, pulling assembly, and reset assembly. This mechanism has advantages such as simple structure, convenient operation, and high reliability, and is suitable for various material storage and conveying systems.

[0031] The bottom of hopper 1 is inclined, and the inclination angle of outlet 2 is greater than that of movable plug 3. This inclined bottom of hopper 1 and outlet 2 design facilitates smoother material flow under gravity. The greater inclination angle of outlet 2 ensures that when movable plug 3 is open, material flows out quickly and in a concentrated manner from outlet 2, reducing the risk of material residue and blockage. The inclination angle design takes into account the material's flowability, allowing it to form a stable flow layer within hopper 1. This design helps prevent dead zones or accumulation of material within hopper 1, thereby improving material utilization and conveying efficiency.

[0032] Furthermore, the pulling assembly includes a fixed base 4, which is disposed on the inner wall of the hopper 1. As a supporting structure for the entire pulling assembly, the fixed base 4 is securely mounted on the inner wall of the hopper 1. A rotating shaft 5 is threaded through the fixed base 4, and a rotating rod 6 is rotatably connected to the rotating shaft 5. The middle of the rotating rod 6 is rotatably connected to a connecting rod 7 via a connecting pin. The rotating rod 6 is connected to the fixed base 4 via the rotating shaft 5, and its middle part is rotatably connected to the connecting rod 7 via a connecting pin. This connection method allows the rotating rod 6 to drive the connecting rod 7 to move up and down when rotating, thereby opening the movable plug 3 to control the opening and closing of the discharge port 2. A through groove 8 is threaded through the rotating rod 6, and a hook 9 is disposed within the through groove 8. The through groove 8, located on the rotating rod 6, provides a sliding space for the hook 9. A movable pull rod 10 is disposed on the hook 9, and a movable plate 11 is fixedly disposed on the pull rod 10. A drive cylinder is externally connected to the movable plate 11, causing the movable plate 11 to move up and down.

[0033] It should be noted that the discharge rate can be adjusted by changing the distance between hook 9 and lever 10. Different materials have different flowability and particle size distribution. Therefore, when adjusting the distance, the characteristics of the material must be fully considered to ensure the stability and efficiency of the discharge process. The distance between hook 9 and lever 10 can be flexibly adjusted according to the conveying requirements and flow rate of the production line to achieve the best discharge effect.

[0034] Furthermore, the reset assembly includes a retaining shaft 12, which is respectively mounted on the fixed base 4 and the rotating rod 6. A tension spring 13 is engaged with each retaining shaft 12. The tension spring 13 provides a reset force to the rotating rod 6. When the movable plug 3 is pulled, the tension spring 13 is stretched and stores energy. When the external force disappears, the tension spring 13 releases its energy, pushing the rotating rod 6, connecting rod 7, and movable plug 3 back to their initial positions.

[0035] It should be further noted that the reset assembly also includes a second fixed seat 14, which is disposed on the inner wall of the hopper 1 opposite to the first fixed seat 4. The second fixed seat 14 and the vertical section of the rotating rod 6 are each provided with a retaining shaft 15, and several retaining shafts 15 are arranged in an array on the vertical section of the rotating rod 6. A tension spring 16 is engaged with one of the retaining shafts 15 on the second fixed seat 14 and one of the retaining shafts 15 on the vertical section of the rotating rod 6. The retaining shafts 15 are respectively disposed on the second fixed seat 14 and the vertical section of the rotating rod 6. The arrangement of several retaining shafts 15 on the vertical section of the rotating rod 6 allows the tension spring 16 to be selectively engaged with different retaining shafts 15, thereby adjusting the magnitude and direction of the reset force. The tension spring 16 is engaged with one of the retaining shafts 15 on the second fixed seat 14 and one of the retaining shafts 15 on the vertical section of the rotating rod 6. Similar to tension spring 13, tension spring 2 16 also provides a restoring force for the rotating rod 6. However, unlike tension spring 13, the position and number of tension spring 2 16 can be adjusted as needed to achieve more precise restoring control.

[0036] It is worth mentioning that tension spring 13 and tension spring 2 16 are doubled and positioned at both ends of the rotating rod 6, providing a uniform force for the rotating rod 6 to drive the movable plug 3 at the bottom of the connecting rod 7 to reset. This ensures that the tension at both ends is uniform and equal when the rotating rod 6 rotates. This design helps reduce the deflection and twisting of the rotating rod 6 during rotation, thereby improving its stability and durability.
