Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to a silo material loading structure. Background Technology

[0002] When loading materials from silos onto transport vehicles, there is typically a vertical drop and a horizontal distance between the silo outlet and the vehicle's cargo compartment. A conveying device is needed to transfer the material from the silo to the truck's cargo compartment. Currently, the mainstream loading structure uses a fixed rigid chute to transfer the material from the silo to the truck's cargo compartment. However, the outlet height and extension length of the fixed rigid chute are not adjustable, and the significant differences in cargo compartment height between different vehicle types (such as flatbed trucks, high-sided trucks, and container trucks) cause the vertical distance between them to dynamically change, leading to the core problem of insufficient spatial adaptability. In practical applications, the following defects exist: First, when the vertical distance between the chute outlet and the truck bed is too high (suitable for low-sided trucks), the impact force of the material falling freely is amplified, causing dust to fly, environmental pollution, and material loss; Second, when the height of the chute outlet is set too low (suitable for low-sided trucks), it cannot extend to the effective loading space of the truck bed when facing high-sided trucks or container trucks, causing the material to spill directly outside the truck or even fail to load; Currently, fixed rigid chutes can only match specific vehicle specifications, requiring transport vehicles to be strictly aligned with the preset loading point, which greatly limits the flexibility of operation. Due to differences in vehicle height, the parking position needs to be adjusted frequently, significantly reducing loading and unloading efficiency. The manual intervention process further aggravates the risk of spillage.

[0003] Therefore, in view of this, the inventors proposed a silo material loading structure to solve the above-mentioned technical problem. Utility Model Content

[0004] The purpose of this utility model is to provide a silo material loading structure to solve the technical problem that the existing loading structure cannot adjust the loading height and extension length, and is not convenient to adapt to the height changes of multiple vehicle models.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A silo material loading structure includes a first conveying structure and a second conveying structure, one end of the first conveying structure is used to connect to the silo, and the other end of the first conveying structure is connected to the second conveying structure.

[0007] The second conveying structure includes a support, a first movable frame and a second movable frame, the first movable frame and the second movable frame being pivotally mounted on the support, and the first movable frame and the second movable frame being able to be angled around the support;

[0008] The first movable frame is connected to the first conveying structure, and the second movable frame is connected to the first movable frame;

[0009] The second conveying structure is movable on the loading platform.

[0010] Furthermore, the first conveying structure includes a connecting cylinder and at least one conveying chamber, each of the conveying chambers being connected to the connecting cylinder, the connecting cylinder being used to connect to the bottom of the silo, and the conveying chamber having a discharge port at one end away from the silo;

[0011] A spiral roller is rotatably connected inside the conveying chamber, and a first motor is provided at one end of the conveying chamber, with the output shaft of the first motor connected to the spiral roller.

[0012] Furthermore, the first movable frame includes a first conveyor frame, a first conveying unit, and a first adjusting unit; the first conveyor frame is hinged to the support, and the first conveying unit and the first adjusting unit are mounted on the first conveyor frame.

[0013] Furthermore, the first conveying unit includes two first conveying rollers rotatably connected to the first conveying frame, and a first conveyor belt is tensioned between the two first conveying rollers;

[0014] The first conveying roller has a first sprocket coaxially connected to both ends.

[0015] Furthermore, the first adjustment unit includes a second motor, a first support frame, and a first screw. The second motor is fixedly installed at the bottom of the first conveyor frame, the first screw is rotatably connected to the bottom of the first conveyor frame, and the output shaft of the second motor is coaxially connected to the first screw.

[0016] The first screw is threadedly connected to a first slider, and the first slider is rotatably connected to a first connecting rod, which is connected to the first conveyor frame.

[0017] Furthermore, the second movable frame includes a second conveyor frame, a second conveying unit, and a second adjusting unit; the second conveyor frame is hinged to the support, and the second conveying unit and the second adjusting unit are mounted on the second conveyor frame;

[0018] A connecting roller is rotatably connected between the first conveyor frame and the second conveyor frame.

[0019] Furthermore, the second conveying unit includes two second conveying rollers rotatably connected to the second conveying frame, and a second conveyor belt is tensioned between the two second conveying rollers;

[0020] The two ends of the second conveying roller are coaxially connected to a second sprocket.

[0021] Crucially, a rotatable connecting roller is installed between the first and second conveyor frames. This design allows the two movable frames to maintain physical connection at their joints while performing their respective tilt adjustments (driven by their own independent adjustment units). The connecting roller adaptively rotates under differences in height and angle, ensuring that material smoothly slides from the first conveyor belt into the second conveyor belt without leakage or jamming. This forms a dynamically flexible, two-stage conveying channel, enabling coordinated control of the end discharge port position in both height and horizontal distance.

[0022] Furthermore, the second adjustment unit includes a third motor, a second support frame, and a second screw. The second motor is fixedly installed at the bottom of the second conveyor frame, and the second screw is rotatably connected to the bottom of the second conveyor frame. The output shaft of the second motor is coaxially connected to the second screw.

[0023] The second screw is threadedly connected to a second slider, and the second slider is rotatably connected to a second connecting rod, which is connected to the second conveyor frame.

[0024] Furthermore, it also includes a power structure, which includes a fourth motor and a converter disposed on one side of the fourth motor. A drive shaft is rotatably connected to the converter. The fourth motor is used to drive the drive shaft to rotate. Drive sprockets are disposed at both ends of the drive shaft. A chain is tensioned between the drive sprockets and the first and second sprockets.

[0025] Furthermore, the bottom of the bracket is provided with multiple pulleys equipped with foot brakes.

[0026] The beneficial effects of this utility model are:

[0027] This invention, by incorporating independently adjustable first and second movable frames, allows for dynamic adjustment of both the discharge height and horizontal extension length of the overall conveying path. When dealing with vehicles of varying heights (such as low-floor flatbed trucks, high-sided trucks, or container trucks), operators can precisely control the vertical drop between the final material drop point and the truck bed, effectively preventing excessive impact from free fall and significantly reducing dust emissions, thus mitigating environmental pollution risks. Simultaneously, the material enters the truck bed in a more controllable manner, reducing material loss due to impact and dispersion, improving overall material utilization, and achieving cleaner and more economical loading operations.

[0028] This structure utilizes a pulley system to allow the entire second conveying structure to move laterally on the loading platform. Combined with the adjustable angles of the first and second movable frames, it completely eliminates the stringent limitations imposed by traditional fixed chutes on vehicle parking positions and vehicle specifications. Operators no longer need to require transport vehicles to be precisely aligned with preset points, nor do they need to frequently direct vehicle adjustments due to differences in truck height. Simply pushing the equipment laterally and adjusting the tilt angle of the movable frames allows for quick and precise adaptation of the discharge port to the effective loading space of trucks of different heights. This greatly simplifies the operation process, reduces manual intervention and waiting time, significantly improves the flexibility and efficiency of overall loading and unloading operations, and effectively reduces the risk of material spillage or even loading failure due to inaccurate vehicle positioning or equipment incompatibility.

The objectives and other advantages of this application may be realized and obtained through the detailed embodiments described below. Attached Figure Description

Detailed Implementation

[0038] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0039] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0040] This embodiment proposes a silo material loading structure for installation on a loading platform 1, with the silo 4 positioned above the loading platform 1, such as... Figures 1 to 7 As shown, it includes a first conveying structure 2 and a second conveying structure 3, one end of the first conveying structure 2 (i.e. Figure 1 In the middle, the right end of the first conveying structure 2 is used to connect with the silo 4, and the other end of the first conveying structure 2 (i.e., Figure 1 In the middle, the left end of the first conveying structure 2 is connected to the second conveying structure 3; as shown Figure 3 As shown, the second conveying structure 3 includes a support 31, a first movable frame 32, and a second movable frame 33. The first movable frame 32 and the second movable frame 33 are pivotally mounted on the support 31, and the first movable frame 32 and the second movable frame 33 can be angled around the support 31. Figure 1 As shown, the first movable frame 32 is located below the first conveying structure 2, and the second movable frame 33 is connected to the first movable frame 32. A loading vehicle 5 is provided at the left end of the second movable frame 33 for conveying the materials on the second movable frame 33 to the compartment of the loading vehicle 5.

[0041] In this example, the first conveying structure 2 serves as the initial conveying unit, with one end connected to the discharge port 23 of the silo 4 to receive materials and transfer them to the second conveying structure 3. The first movable frame 32 is connected to the first conveying structure 2. After receiving materials, it can adjust its own tilt angle to adjust the height of the conveyed materials. The second movable frame 33 is pivotally connected to the support 31 and connected to the first movable frame 32. After the materials transition from the first movable frame 32 to the second movable frame 33, their angle can also be adjusted in a similar way to further change the extension length and height of the conveying path to adapt to the carriages of different loading vehicles 5 (such as flatbed trucks, high-sided trucks, etc.).

[0042] The second conveying structure 3 can move on the loading platform 1. Specifically, the bottom of the support 31 is equipped with multiple pulleys 7 with foot brakes. When the second conveying structure 3 needs to move laterally on the loading platform 1 to align with the loading vehicle 5 for loading, the operator can push the support 31, and the multiple pulleys 7 will roll to achieve flexible displacement. Lateral adjustment can be made to ensure that the end of the second movable frame 33 is aligned with the loading vehicle 5 to reduce material spillage. After positioning, the foot brake devices (such as brake pads or locking buckles) of all pulleys 7 are stepped on to lock them firmly, effectively preventing the support 31 from sliding accidentally during operation and ensuring that the loading position is stable and reliable.

[0043] Before loading, the operator can adjust the height of the truck bed according to the height of the truck bed. For example, the second movable frame 33 can be pivoted downward to cover the loading of the low flatbed truck and avoid dust flying due to free fall impact; or it can be pivoted upward to meet the material loading of the high-sided truck. By adjusting the pivot angle and moving the position, the height and distance of the discharge port 23 can be dynamically optimized to ensure efficient loading and unloading, reduce material loss, and improve operational flexibility. It is especially suitable for the loading platform 1 environment. The entire workflow is seamless and adaptable to multiple vehicle models.

[0044] As a preferred embodiment, such as Figure 2 As shown, the first conveying structure 2 includes a connecting cylinder 21 and at least one conveying chamber 22. Each conveying chamber 22 is connected to the connecting cylinder 21. In this embodiment, the number of conveying chambers 22 is preferably two. The connecting cylinder 21 is used to connect to the bottom of the silo 4, and the end of the conveying chamber 22 away from the silo 4 (i.e., Figure 2 A discharge port 23 is provided on the bottom left side of the middle conveyor hopper 22.

[0045] A spiral roller 24 is rotatably connected inside the conveying chamber 22. A first motor (not shown) is installed at the right end of the conveying chamber 22, and the output shaft of the first motor is connected to the spiral roller 24.

[0046] In this embodiment, the connecting cylinder 21 is firmly connected to the discharge position at the bottom of the silo 4, serving as the initial receiving point for the material. After flowing into the connecting cylinder 21 under gravity, the material is distributed to one or more connected conveying silos 22. Inside each conveying silo 22, the key component is the spiral roller 24, driven by a first motor. Its output shaft drives the spiral roller 24 to rotate at high speed within the conveying silo 22. The rotating spiral roller 24 utilizes the axial thrust generated by its spiral blades (threads) to continuously push the material entering the conveying silo 22 to the left along the inner wall of the conveying silo 22 (axial conveying). Finally, the material pushed to the other end of the conveying silo 22 is smoothly discharged from the discharge port 23 and guided to the first movable frame 32 of the downstream second conveying structure 3, thus completing the material transfer task of this conveying stage.

[0047] As a preferred embodiment, such as Figure 3 and Figure 5 As shown, the first movable frame 32 includes a first conveyor frame 321, a first conveyor unit 322 and a first adjustment unit 323; the left end of the first conveyor frame 321 is hinged to the bracket 31, and the first conveyor unit 322 and the first adjustment unit 323 are mounted on the first conveyor frame 321.

[0048] The first conveying unit 322 includes two first conveying rollers 3221 rotatably connected to the first conveying frame 321, and a first conveyor belt 3222 is tensioned between the two first conveying rollers 3221; the two ends of the left first conveying roller 3221 are coaxially connected to a first sprocket 3223.

[0049] The first adjustment unit 323 includes a second motor 3231, a first support frame 3232, and a first screw 3233. The second motor 3231 is fixedly installed at the bottom of the first conveyor frame 321, and the first screw 3233 is rotatably connected to the bottom of the first conveyor frame 321. The output shaft of the second motor 3231 is coaxially connected to the first screw 3233. Figure 4 As shown, a first slider 3234 is threadedly connected to the first screw 3233, and a first connecting rod 3235 is rotatably connected to the first slider 3234. The first connecting rod 3235 is connected to the first conveyor frame 321.

[0050] In this embodiment, the first conveying unit 322 is responsible for material transfer. Two first conveying rollers 3221 are rotatably mounted on the first conveying frame 321, and the first conveying belt 3222 is tensioned between the two first conveying rollers 3221 to form a continuous conveying surface. After the second motor 3231 starts, its output shaft drives the first screw 3233, which is threadedly connected to it, to rotate. The rotation of the first screw 3233 forces the threaded first slider 3234 to move horizontally along the axis of the first screw 3233. The displacement of the first screw 3233 causes the first connecting rod 3235, which is rotatably connected to it, to move. Since the first connecting rod 3235 is rotatably connected to the first conveying frame 321, as the first screw 3233 moves, the first connecting rod 3235 pushes the first conveying frame 321 to pivot around its hinge point with the support 31, thereby adjusting the tilt angle of the entire first conveying frame 321. This adjustment can be made dynamically during the loading process. For example, when facing a high-sided truck, the angle can be raised to increase the drop, or when facing a low-sided truck, the angle can be lowered to extend the horizontal conveying distance. The power transmission and angle control do not interfere with each other throughout the process, ensuring continuous and stable material conveying.

[0051] As a preferred embodiment, such as Figure 3 and Figure 5 As shown, the second movable frame 33 includes a second conveyor frame 331, a second conveyor unit 332, and a second adjustment unit 333. The right end of the second conveyor frame 331 is hinged to the bracket 31. The second conveyor unit 332 and the second adjustment unit 333 are mounted on the second conveyor frame 331. The second conveyor unit 332 includes two second conveyor rollers 3311 rotatably connected to the second conveyor frame 331. A second conveyor belt 3312 is tensioned between the two second conveyor rollers 3311. The two ends of the second conveyor roller 3311 located on the right side of the second conveyor frame 331 are coaxially connected to a second sprocket 3313.

[0052] In this embodiment, the second conveying unit 332 on the second conveying frame 331 undertakes the task of relay transportation of materials, and two second conveying rollers 3311 are rotatably mounted on the second conveying frame 331. The second conveying belt 3312 tensioned between the two second conveying rollers 3311 forms a continuous carrying surface.

[0053] A connecting roller 334 is rotatably connected between the first conveyor frame 321 and the second conveyor frame 331. After the material is flexibly transferred from the connecting roller 334 at the end of the first movable frame 32 to the second conveyor belt 3312, it is received by the second conveyor belt 3312 and continues to be transported forward. This design allows the two conveyor frames (the first conveyor frame 321 and the second conveyor frame 331) to maintain physical connection at their joints when performing their respective tilt angle adjustments (driven by their respective independent adjustment units).

[0054] As a preferred embodiment, such as Figure 3 and Figure 5As shown, the second adjustment unit 333 includes a third motor 3231, a second support frame 3332, and a second screw 3333. The second motor 3231 is fixedly installed at the bottom of the second conveyor frame 331, and the second screw 3333 is rotatably connected to the bottom of the second conveyor frame 331. The output shaft of the second motor 3231 is coaxially connected to the second screw 3333. A second slider (not shown) is threaded onto the second screw 3333, and a second connecting rod (not shown) is rotatably connected to the second slider. The second connecting rod is connected to the second conveyor frame 331. After the third motor 3331 starts, its output shaft drives the second screw 3333, which is coaxially connected to it, to rotate. When the second screw 3333 rotates, the second slider sleeved on it moves horizontally along the screw axis under the action of the thread. The displacement of the second slider is converted into a pushing or pulling force on the second conveyor frame 331 through the rotating second connecting rod. Since the bottom of the second conveyor frame 331 is hinged to the support 31, the entire conveyor frame is forced to pivot around the hinge point, thereby changing the output height and extension angle of the second conveyor belt 3312.

[0055] It should be noted that the first conveyor belt 3222 and the second conveyor belt 3312 in this embodiment are not limited to the flat conveyor belt in the example. They can be V-shaped or other types of conveyor belts, and can be selected according to the specific materials to be conveyed on site.

[0056] As a preferred embodiment, such as Figure 6 and Figure 7 As shown, it also includes a power structure, which includes a fourth motor 61 and a converter 62 disposed on one side of the fourth motor 61. A drive shaft 63 is rotatably connected to the converter 62. The fourth motor 61 is used to drive the drive shaft 63 to rotate. Drive sprockets 64 are disposed at both ends of the drive shaft 63. A chain 65 is tensioned between the drive sprockets 64 and the first sprocket 3223 and the second sprocket 3313.

[0057] Specifically, the converter 62 is equipped with a driven bevel gear and a driving bevel gear. The driven bevel gear is fixed in the middle of the driving shaft 63. The output shaft of the fourth motor 61 is connected to the driving bevel gear. The driving bevel gear meshes with the driven bevel gear. When the fourth motor 61 runs, it drives the driving shaft 63 to rotate. The driving sprockets 64 at both ends of the driving shaft 63 rotate accordingly. The power is synchronously transmitted to the first sprocket 3223 of the first movable frame 32 and the second sprocket 3313 of the second movable frame 33 through the tensioned chains 65, so as to realize the linkage operation of the two conveyor belts 3312 and ensure continuous and coordinated material conveying.

[0058] This application, by setting up a first movable frame 32 and a second movable frame 33 that can be independently adjusted in angle, allows operators to precisely control the vertical drop between the final material drop point and the truck bed when dealing with vehicles of different heights (such as low-floor flatbed trucks, high-sided trucks, or container trucks). This effectively avoids the aggravated impact of material free fall caused by excessive drop, thereby significantly reducing dust emissions and the risk of environmental pollution. Simultaneously, the material enters the truck bed in a more controllable manner, reducing material loss due to impact and dispersion, improving the overall utilization rate of the material, and achieving cleaner and more economical loading operations. Meanwhile, the second conveying structure 3 can move laterally on the loading platform 1. Combined with the angle adjustment function of the first movable frame 32 and the second movable frame 33, it completely solves the strict restrictions of traditional fixed chutes on vehicle parking positions and vehicle specifications. Operators do not need to require transport vehicles to be strictly aligned with preset points, nor do they need to frequently direct vehicles to adjust parking positions due to differences in car height. They only need to simply push the equipment laterally and adjust the tilt angle of the first movable frame 32 and the second movable frame 33 to quickly and accurately adapt the discharge port 23 to the effective loading space of car bodies of different heights. This greatly simplifies the operation process, significantly improves the flexibility and efficiency of the overall loading and unloading operation, and effectively reduces the risk of material spillage or even loading failure caused by inaccurate parking of the loading vehicle 5 or incompatibility of the equipment.

[0059] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
