Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting technology, and in particular to a material conveying device. Background Technology
[0002] Material lifting devices are widely used in industrial production, construction, and logistics transportation as key equipment for vertical or inclined material conveying, handling various materials such as ores, building materials, and grains. Material lifting devices typically include a drive mechanism (such as a motor and reducer), transmission components (such as a conveyor belt, chain, or wire rope), load-bearing components (such as hoppers and conveyor plates), and a protective structure. The main function of the protective structure is to prevent materials from scattering or splashing during the lifting process due to vibration, centrifugal force, or accidental collisions, while also preventing external environmental interference with the lifting process.
[0003] However, existing protective structures are mostly connected to the main body of the device by welding, bolting and other methods. When materials are tilted or lifted at high speed, they are prone to direct collision with the protective structure (such as baffles and side plates). When the protective structure is damaged by long-term collisions, such as deformation and cracks, it is necessary to use tools to disassemble the bolts or cut the welded parts one by one. The disassembly process is time-consuming and laborious, and frequent disassembly can easily lead to stripping of the connection and reduction of structural strength, resulting in low practicality. Utility Model Content
[0004] The purpose of this utility model is to provide a material conveying device that is easy to disassemble and replace, saves time and effort, and is highly practical.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A material conveying device, comprising:
[0007] Two protective shells are distributed at intervals and a conveying channel is formed between the two protective shells. Each protective shell has a first end and a second end. The height of the protective shell gradually increases from the first end to the second end. The direction from the first end to the second end is the material conveying direction.
[0008] The bracket is used to support the two protective shells;
[0009] The conveying assembly includes a drive unit and two rotating drums. The two rotating drums are respectively disposed at the first end and the second end of the protective shell. Both rotating drums are rotatably connected between the two protective shells. The drive unit is installed on the side of either protective shell facing away from the other protective shell. The rotating drum near the second end is coaxial with and fixedly connected to the output end of the drive unit. The two rotating drums are connected by a conveyor belt. The drive unit can drive the rotating drums to rotate.
[0010] The protective structure is located at the second end of the protective shell. The protective structure is detachably connected to the protective shell via a snap-fit structure and can prevent materials from falling.
[0011] Preferably, the snap-fit structure includes:
[0012] The housing and the sleeve are fixed inside the housing and have an elastic element inside the sleeve.
[0013] The insert rod is movable and can pass through the housing. One end of the elastic element is connected to or abuts against the insert rod, and the other end is connected to or abuts against the sleeve. The insert rod has a snap-fit position and a release position. When the insert rod is in the snap-fit position, the end of the insert rod away from the elastic element extends into the protective housing to fix the protective structure relative to the protective housing. When the insert rod is in the release position, the end of the insert rod away from the elastic element separates from the protective housing to allow the protective structure to separate from the protective housing.
[0014] Preferably, the outer surface of the housing is provided with a plurality of first through grooves, the outer surface of the sleeve is provided with a plurality of second through grooves, and the outer surface of the insert rod is provided with a plurality of connecting rods along its own radial direction. The plurality of connecting rods, the plurality of first through grooves and the plurality of second through grooves are arranged in a one-to-one correspondence. The connecting rods can be slidably disposed in the corresponding first through grooves and second through grooves, and the outer surface of the connecting rods is respectively in contact with the inner wall of the first through groove and the second through groove.
[0015] Preferably, the snap-fit structure also includes a pull ring, which is sleeved on the outside of the insert rod and fixedly connected to multiple connecting rods.
[0016] Preferably, the protective structure includes a baffle and two connecting plates connected to the baffle. The two connecting plates are parallel and spaced apart, and the two connecting plates are detachably connected to the two protective shells by a snap-fit structure.
[0017] Preferably, both connecting plates are provided with reinforcing ribs.
[0018] Preferably, a protective pad is provided on the side of the baffle facing the conveyor belt.
[0019] Preferably, the conveyor belt is equipped with a conveying component, which has a material storage space.
[0020] Preferably, multiple conveying components are provided, and the multiple conveying components are distributed at intervals along the material conveying direction.
[0021] Preferably, the material conveying device also includes a storage bin, with the first ends of the two protective shells located inside the storage bin, allowing the material inside the storage bin to enter the material storage space of the conveying component.
[0022] The beneficial effects of this utility model are:
[0023] This utility model provides a material conveying device. Material is placed onto a conveyor belt from the first end of a protective shell. A drive unit is activated, causing a rotating drum near the second end to rotate. The conveyor belt and the rotating drum at the other end are linked, causing the conveyor belt to move along the material conveying direction, and the material is conveyed upwards with the conveyor belt. The protective shells on both sides form a conveying channel, which can limit the lateral deviation of the material and ensure its stable movement along a preset path, reducing the risk of deviation during the conveying process. When the material reaches the second end from the first end, the protective structure can prevent the material from falling due to inertia. After being lifted, the material continues to be conveyed by the conveyor belt for the next cycle.
[0024] Because materials used over a long period of time can collide with and damage the protective structure, it is necessary to replace and maintain the protective structure. By directly disassembling the snap-fit structure, the protective structure can be removed from the protective shell without tools, which can quickly disassemble and replace it, reducing maintenance difficulty and downtime. Disassembly is convenient, saving time and effort. After the operation is completed, the new protective structure can be directly snapped back onto the protective shell through the snap-fit structure, which is convenient for replacing the new protective structure and has strong practicality.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0039] like Figure 1-4As shown, an embodiment of this utility model provides a material conveying device, including two protective shells 1, a support 3, a conveying assembly 2, and a protective structure. The two protective shells 1 are spaced apart, forming a conveying channel between them. Each protective shell 1 has a first end and a second end, with its height gradually increasing from the first end to the second end. This direction is the material conveying direction. The support 3 supports the two protective shells 1. The conveying assembly 2 includes a drive component 22 and two rotating drums 21, which are respectively disposed at the first and second ends of the protective shells 1. Both rotating drums 21 are rotatably connected between the two protective shells 1. The drive component 22 is installed on the side of any protective shell 1 facing away from the other. The rotating drum 21 near the second end is coaxially and fixedly connected to the output end of the drive component 22. The two rotating drums 21 are connected by a conveyor belt 23. The drive component 22 can drive the rotating drum 21 to rotate. The protective structure is located at the second end of the protective shell 1 and is detachably connected to the protective shell 1 via a snap-fit structure 4. The protective structure can prevent material from falling. Specifically, the drive component 22 is a motor.
[0040] Material is placed onto conveyor belt 23 from the first end of protective shell 1. Drive unit 22 is activated, causing the rotating drum 21 near the second end to rotate. This rotation, linked to the rotating drum 21 at the other end, causes conveyor belt 23 to move along the material conveying direction, transporting the material upwards. The two protective shells 1 form a conveying channel, limiting lateral material deviation and ensuring stable movement along a preset path, reducing the risk of deviation during transport. When material reaches the second end from the first end, the protective structure prevents it from falling due to inertia. After being lifted, the material continues to be conveyed by conveyor belt 23 for the next cycle.
[0041] Because long-term use of materials can cause damage to the protective structure due to collisions, the protective structure needs to be replaced and maintained. By removing the snap-fit structure 4, the protective structure can be directly removed from the protective shell 1. It can be quickly disassembled and replaced without tools, reducing maintenance difficulty and downtime. Disassembly is convenient, saving time and effort. After the operation is completed, the new protective structure can be directly snapped back onto the protective shell 1 through the snap-fit structure 4, which is convenient for replacing the new protective structure and has strong practicality.
[0042] Furthermore, the conveying assembly 2 also includes a tensioning structure configured to adjust the tension of the conveyor belt 23 acting on the two rotating drums 21.
[0043] For example, the tensioning structure includes a tensioning roller located between two rotating drums 21 and disposed on the side of the conveyor belt 23 that is not carrying material. The tensioning roller is rotatably connected to the protective shell 1 and is fitted to the conveyor belt 23.
[0044] By setting up a tensioning structure, the conveyor belt 23 can be reliably and effectively tensioned, preventing it from loosening during transmission and ensuring the stability of material conveying. It should be noted that the tensioning structure is a fairly standard structure in the field and will not be described in detail here.
[0045] Furthermore, such as Figure 2 As shown, the conveyor belt 23 is equipped with a conveying component 24, which has a material storage space. Specifically, the conveying component 24 is a hopper used to receive materials and prevent them from falling during the conveying process.
[0046] Furthermore, multiple conveying components 24 are provided, and the multiple conveying components 24 are distributed at intervals along the material conveying direction.
[0047] By distributing multiple conveyor components 24 at intervals along the material conveying direction, and by controlling the spacing between the conveyor components 24 and the transmission speed of the conveyor belt 23, it is possible to achieve quantitative and separate conveying of materials, thereby avoiding material accumulation or chaotic conveying rhythm.
[0048] Furthermore, the protective structure includes a baffle 6 and two connecting plates 7 connected to the baffle 6. The two connecting plates 7 are parallel and spaced apart, and the two connecting plates 7 are detachably connected to the two protective shells 1 through a snap-fit structure 4.
[0049] like Figure 3 As shown, two parallel and spaced connecting plates 7 are connected to the protective shells 1 on both sides, forming symmetrical support for the baffle 6. This prevents the baffle 6 from tilting or deforming due to unilateral force, thus enhancing the overall rigidity of the protective structure. As a direct blocking component, the baffle 6 can receive or buffer the material tilted by the conveyor 24 through its own planar structure when the material is conveyed to the second end, preventing the material from falling due to inertia.
[0050] It should be noted that the area of the baffle 6 can be designed according to the width of the conveyor channel to ensure complete coverage of the conveyor belt 23 and the conveyor component 24, thereby improving the reliability of the blocking.
[0051] Furthermore, both connecting plates 7 are equipped with reinforcing ribs. This design further enhances the overall rigidity of the protective structure.
[0052] Furthermore, a protective pad 8 is provided on the side of the baffle 6 facing the conveyor belt 23. Specifically, the protective pad 8 is made of elastic materials such as rubber and polyurethane.
[0053] When the material in the conveyor 24 falls onto the baffle 6, the protective pad 8 can absorb the impact energy through its own deformation, which can buffer the impact of the material on the baffle 6, prevent the material from directly colliding with the baffle 6 and causing damage, and at the same time reduce the damage such as dents and cracks caused by long-term impact on the baffle 6, thus extending its service life.
[0054] Furthermore, such as Figure 4As shown, the snap-fit structure 4 includes a housing 41, a sleeve 42, and a rod 44. The sleeve 42 is fixed inside the housing 41, and an elastic element 43 is provided inside the sleeve 42. The rod 44 can be movably inserted through the housing 41. One end of the elastic element 43 is connected to or abuts against the rod 44, and the other end is connected to or abuts against the sleeve 42. The rod 44 has a snap-fit position and a release position. When the rod 44 is in the snap-fit position, the end of the rod 44 away from the elastic element 43 extends into the protective housing 1 to fix the protective structure relative to the protective housing 1. When the rod 44 is in the release position, the end of the rod 44 away from the elastic element 43 separates from the protective housing 1 to allow the protective structure to be separated from the protective housing 1. Specifically, the elastic element 43 is a compression spring.
[0055] During normal operation of the material conveying device, the protective structure is engaged with the protective shell 1 via the snap-fit structure 4, i.e., the insertion rod 44 is in the snap-fit position. At this time, the elastic element 43 inside the sleeve 42 is in an extended state, providing elastic force within the sleeve 42. The elastic element 43 can push the insertion rod 44 away from the sleeve 42, causing the end of the insertion rod 44 away from the elastic element 43 to pass through the connecting plate 7 and extend into the pre-set slot or hole in the protective shell 1. At this time, the protective structure forms a mechanical lock with the protective shell 1 through the insertion rod 44, achieving relative fixation.
[0056] When the protective structure is damaged and needs to be replaced, it needs to be disassembled. This involves switching the insert rod 44 to the disengaged position, applying force to the insert rod 44 to move it along the direction of the compression elastic element 43. The elastic element 43 is compressed, allowing the insert rod 44 to move into the sleeve 42 until the end of the insert rod 44 away from the elastic element 43 is completely out of the slot or hole of the protective shell 1, separating the insert rod 44 from the protective shell 1. At this point, the locking between the protective structure and the protective shell 1 is released, and the protective structure can be directly removed.
[0057] After replacing the new protective structure, the force applied to the insertion rod 44 is removed, the elastic element 43 returns to its extended state, and the insertion rod 44 is pushed to pass through the connecting plate 7 and extend into the protective shell 1 again, that is, switch to the snap-fit position, and complete the re-locking of the snap-fit structure 4 and the protective shell 1, fixing the protective structure and the protective shell 1 relative to each other.
[0058] Furthermore, the outer surface of the housing 41 is provided with a plurality of first through grooves 47, the outer surface of the sleeve 42 is provided with a plurality of second through grooves 48, and the outer surface of the insertion rod 44 is provided with a plurality of connecting rods 45 along its own radial direction. The plurality of connecting rods 45, the plurality of first through grooves 47 and the plurality of second through grooves 48 are arranged in a one-to-one correspondence. The connecting rods 45 can be slidably disposed in the corresponding first through grooves 47 and second through grooves 48, and the outer surface of the connecting rods 45 is respectively in contact with the inner wall of the first through grooves 47 and second through grooves 48.
[0059] The connecting rod 45 is slidably fitted into the first through groove 47 of the housing 41 and the second through groove 48 of the sleeve 42, forming a limiting and guiding effect on the insertion rod 44. When the insertion rod 44 moves axially under the action of the elastic member 43, the connecting rod 45 slides along the inner wall of the through groove, which can limit the circumferential rotation and radial offset of the insertion rod 44, ensuring that the insertion rod 44 always moves along the preset axis, and improving the smoothness of the locking and unlocking operation.
[0060] Furthermore, the snap-fit structure 4 also includes a pull ring 46, which is sleeved on the outside of the insertion rod 44 and fixedly connected to multiple connecting rods 45.
[0061] Pull ring 46 is fixedly connected to all connecting rods 45. Operators can pull or press pull ring 46 to synchronously drive all connecting rods 45 to slide along the through groove, so that the insertion rod 44 is subjected to uniform force and always maintains axial movement, realizing the "one-click" engagement and disengagement of the insertion rod 44.
[0062] Furthermore, the material conveying device also includes a storage bin 5, with the first ends of the two protective shells 1 located inside the storage bin 5, and the material inside the storage bin 5 can enter the material storage space of the conveying component 24.
[0063] The storage bin 5 can pre-store a certain amount of material. The first end of the protective shell 1 is located inside the storage bin 5, so that the conveyor 24 can directly receive the material from the storage bin 5 and convey it upward when it is running in a cycle with the conveyor belt 23. Moreover, the storage bin 5 can also collect and store the material after it has been lifted by the conveyor belt 23 and the conveyor 24, realizing continuous "storage-conveying" operation and improving overall production efficiency.
[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
