Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to an adjustable length belt conveyor. Background Technology

[0002] A belt conveyor is a mechanical device that uses a continuously moving conveyor belt to transport materials. It mainly consists of a conveyor belt, a drive unit, rollers, idlers, a tensioning device, and a frame. Its working principle is that the drive unit drives the drive rollers to rotate, and the friction force makes the conveyor belt rotate, transporting materials from the feed inlet to the discharge outlet. It has the characteristics of large conveying capacity, stable operation, and simple operation. According to the conveying direction, it can be divided into horizontal belt conveyors and other types. It is widely used in many industries such as mining, ports, chemicals, and grain.

[0003] A search revealed that Chinese patent CN219408008U discloses an adjustable-length belt conveyor, comprising a frame, adjusting frames, transmission rollers, a conveyor belt, a motor, an adjusting mechanism, and reinforcing bolts. Two adjusting frames are mounted on the frame, and the frame is provided with mounting slots for moving the adjusting frames. Reinforcing bolts for fixing the adjusting frames are installed at both ends of the frame. The adjusting frames are provided with multiple threaded holes for the reinforcing bolts to pass through. The overall conveying length is easy to adjust and convenient to use.

[0004] After the conveyor belt length is adjusted, the lack of protective shielding on the outside not only makes it easy for personnel to accidentally touch it and cause mechanical injury, but also makes it easy for external debris to enter and contaminate materials, aggravating component wear. At the same time, the lack of boundary constraints will cause the conveyor belt to run off-center and sway, affecting the stability of operation. The lack of support in the middle of the conveyor belt will cause it to sag and deform when carrying materials, resulting in material spillage, reduced conveying efficiency, and long-term uneven stress will accelerate the aging and damage of the conveyor belt, increasing maintenance costs and downtime risks. Utility Model Content

At the same time, the lack of boundary constraints can cause the conveyor belt to deviate and sway, affecting operational stability. Furthermore, the lack of support in the middle of the conveyor belt will cause it to sag and deform when carrying materials, resulting in material spillage, reduced conveying efficiency, and long-term uneven stress will accelerate the aging and damage of the conveyor belt, increasing maintenance costs and downtime risks.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1:

[0034] Please see Figures 1-4 This embodiment provides an adjustable-length belt conveyor that allows for both extension and retraction of the conveyor belt body 1 and provides external protection. The specific concept is as follows:

[0035] The adjustable length belt conveyor includes a conveyor belt body 1. In addition, the adjustable length belt conveyor also includes a first protective fence 2 and a second protective fence 203 disposed on both sides of the conveyor belt body 1. The first protective fence 2 and the second protective fence 203 are used to install the conveyor belt body 1. At the same time, the first protective fence 2 and the second protective fence 203 can be extended to both sides by lateral movement, thereby increasing the length of the conveyor belt body 1. The first protective fence 2 and the second protective fence 203 can also serve as isolation.

[0036] In order to drive the first protective fence 2 and the second protective fence 203, this embodiment provides a telescopic component that can drive the first protective fence 2 and the second protective fence 203 to move laterally to both sides, thereby increasing the length of the conveyor belt body 1.

[0037] The telescopic component includes: a table 201 positioned below the conveyor belt body 1; a mounting plate 202 fixedly connected to the upper surface of the table 201; a first slide rail 204 fixedly connected to one side of the mounting plate 202; a first slider 205 slidably connected to one side of the first slide rail 204; the first slider 205 is used to fix the side plate 3, ensuring its stability in the vertical direction; a second slide rail 207 and a third slide rail 209 fixedly connected to the other side of the mounting plate 202; a second slider 208 slidably connected to one side of the second slide rail 207, used to fix the second protective fence 203, increasing its lateral stability. To improve sliding stability, a third slider 210 is slidably connected to one side of the third slide rail 209 to fix the first protective fence 2 and increase the stability of the first protective fence 2 in lateral sliding. At the same time, a lifting cylinder 211 installed on one side of the mounting plate 202 is used to drive the side plate 3 fixedly connected to its end to move vertically. The inner sides of both ends of the side plate 3 are rotatably connected to connecting arms 206. The ends of the two connecting arms 206 are rotatably connected to the inner sides of the ends of the second protective fence 203 and the first protective fence 2, respectively, to pull or push the first protective fence 2 and the second protective fence 203 to move laterally.

[0038] In the specific implementation process, when the user needs to extend the conveyor belt body 1, the conveyor belt body 1 is first disassembled. At this time, the lifting cylinder 211 is activated, the length of the lifting cylinder 211 is shortened, and the side plate 3 is moved vertically downward. While the side plate 3 moves vertically downward on one side of the first slide rail 204, it will push the first protective fence 2 and the second protective fence 203 to move to both ends through the connecting arms 206 on both sides. At the same time, with the connection of the second slide rail 207 and the third slide rail 209, the lateral movement is more stable. After reaching the appropriate position, the lifting cylinder 211 is closed. Then the conveyor belt body 1 is installed at the end of the first protective fence 2 and the second protective fence 203, and a suitable conveyor belt can be replaced.

[0039] Example 2:

[0040] Please see Figure 1 This embodiment provides an adjustable-length belt conveyor that facilitates support of the middle part of the conveyor belt body 1. The specific concept is as follows:

[0041] The adjustable length belt conveyor includes a conveyor belt body 1. In addition, the adjustable length belt conveyor also includes a first protective fence 2 and a second protective fence 203 disposed on both sides of the conveyor belt body 1. The first protective fence 2 and the second protective fence 203 are used to install the conveyor belt body 1. At the same time, the first protective fence 2 and the second protective fence 203 can be extended to both sides by lateral movement, thereby increasing the length of the conveyor belt body 1. The first protective fence 2 and the second protective fence 203 can also serve as isolation.

[0042] In order to support the middle part of the conveyor belt body 1, this embodiment provides a support member. After the length of the conveyor belt body 1 is increased, it can provide additional support to the inner side of the middle part of the conveyor belt body 1, thereby increasing the stability of the conveyor belt body 1 during operation.

[0043] The support includes: a connecting block 301 fixedly connected to the outer side of the top of the side plate 3; a support column 302 rotatably connected to the inner side of the two connecting blocks 301; the support column 302 is located on the inner side of the middle part of the conveyor belt body 1 and contacts the inner side of the top of the conveyor belt body 1, and can rotate with the conveyor belt body 1.

[0044] In the specific implementation process, when the side plate 3 descends vertically, it drives the first protective fence 2 and the second protective fence 203 to move to the designated positions at both ends. At this time, when installing the conveyor belt body 1, the support column 302 is set on the inner side of the middle of the conveyor belt body 1, so that the middle of the conveyor belt body 1 can be supported. When the side plate 3 rises and the length of the conveyor belt body 1 shortens, the support column 302 rises vertically with the side plate 3. The support column 302 is set above the conveyor belt body 1 and will not interfere with the conveyor belt body 1.

[0045] Working principle:

[0046] Based on Example 1, when it is necessary to extend the conveyor belt body 1, the lifting cylinder 211 is activated after disassembling the conveyor belt body 1 to shorten its length and drive the side plate 3 to move vertically downward. During the downward movement of the side plate 3 on one side of the first slide rail 204, the first protective fence 2 and the second protective fence 203 are pushed to both ends by the connecting arms 206 on both sides. At the same time, the lateral movement is ensured to be stable under the connection of the second slide rail 207 and the third slide rail 209. After reaching the position, the lifting cylinder 211 is closed, the conveyor belt body 1 is reinstalled, and the conveyor belt is replaced. This device realizes flexible adjustment of the length, which can be quickly adjusted according to the actual use scenario. The conveying distance can be quickly adjusted to meet the material transfer needs under different working conditions, avoiding the applicability limitations caused by fixed length. The first protective fence 2 and the second protective fence 203 play a protective role in the structure. After moving to both ends, they can form a boundary protection for the conveyor belt body 1, reducing the risk of external debris intrusion or accidental contact by personnel. At the same time, during the movement, through cooperation with components such as the connecting arm 206, the second slide rail 207, and the third slide rail 209, the stability of the overall structure is enhanced, reducing the shaking or deviation of the equipment during operation. This not only ensures the safe operation of the equipment but also extends the service life of each component.

[0047] Based on Embodiment 2, when the side plate 3 descends vertically, causing the first protective fence 2 and the second protective fence 203 to move to designated positions at both ends, the support column 302 is positioned on the inner side of the middle of the conveyor belt body 1 to provide support. Conversely, when the side plate 3 rises, shortening the length of the conveyor belt body 1, the support column 302 rises vertically along with the side plate 3 and is positioned above the conveyor belt body 1. This design achieves dynamic support and protection for the conveyor belt body 1 from the support column 302. In the extended state of the conveyor belt body 1, the support column 302 provides stable support to its middle section, preventing damage due to increased length. The addition of support columns causes the middle part of the conveyor belt body 1 to sag or deform under stress, ensuring the smoothness of the conveyor. When the conveyor belt body 1 is shortened, the support column 302 moves up to the upper position along with the side plate 3, which can form a shield and protection for the upper part of the conveyor belt body 1, reducing the impact of falling debris or external force on the conveyor belt body 1. At the same time, the dynamic following design of the support column 302 ensures that the conveyor belt body 1 always receives structural support and protection during the entire length adjustment process. This not only improves the operational reliability of the equipment under different length conditions, but also enhances the protection effect of the conveyor belt body 1 through the position change of the support column 302.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
