DETAILED DESCRIPTION
[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.
[0022] Embodiment: A conveyor belt sealing device that is easy to maintain, such as Figures 1-6As shown, it includes a mounting base 1, a conveyor belt 2, a lower hopper 3, a discharge plate 4, a fixed frame 5, a sliding frame 51, a folding cover 52, a pulling member 53, a spring 54, a limit block 55 and a pull ring 56. The mounting base 1 serves as the basic frame of the entire device, supporting all other components and ensuring their correct installation and positioning. The front of the mounting base 1 is provided with an extension portion, which helps to better control the flow direction of the material and reduce the risk of material scattering. A conveyor belt 2 is installed between the two sides of the lower part of the mounting base 1. The conveyor belt 2 is responsible for the transportation of the material. The two sides of the top of the mounting base 1 are A lower hopper 3 is provided between them for the introduction of materials to ensure that the materials can fall smoothly onto the conveyor belt 2, thereby realizing transportation. A discharge plate 4 is provided between the two sides of the front of the mounting seat 1, and the discharge plate 4 is located above the extension of the mounting seat 1. The discharge plate 4 is inclined to help the materials slide down. The discharge plate 4 helps the materials to be smoothly unloaded from the conveyor belt 2. The rear end of the discharge plate 4 contacts the front end of the conveyor belt 2. There are two fixing frames 5. One of the fixing frames 5 is provided on the front side of the lower hopper 3, and the second fixing frame 5 is provided between the two sides of the top of the mounting seat 1. The second fixing frame 5 is located on the mounting seat 1. In the front position, a sliding frame 51 is provided on the top of the mounting seat 1, which can slide along the top of the mounting seat 1. The sliding frame 51 is located in front of the fixed frame 5, and a folding cover 52 is provided between the sliding frame 51 and the fixed frame 5. The folding cover 52 plays a sealing role to prevent dust or material leakage. At the same time, it can be expanded or folded as the sliding frame 51 moves. Pulling members 53 are slidably provided on both sides of the lower part of the fixed frame 5. Springs 54 are provided between the pulling members 53 on both sides and the fixed frame 5. The springs 54 provide a reset force so that the pulling member 53 can return to its original position when no external force is applied. In the initial position, the pulling members 53 on both sides are tilted close to one end of the fixed frame 5, and the limit blocks 55 are symmetrically arranged on both sides of the lower part of the sliding frame 51. One end of the limit blocks 55 on both sides is tilted, and the tilted part of the limit block 55 is in contact with the tilted part of the pulling member 53. The pulling member 53 locks and unlocks the sliding frame 51 through the interaction with the limit block 55, which is convenient for maintenance operations. Pull rings 56 are provided on both sides of the lower outward part of the sliding frame 51. The pull rings 56 facilitate the operator to manually adjust the position of the sliding frame 51 to carry out maintenance work.
[0023] like Figure 1 、 Figure 5 and Figure 6As shown, it also includes a connecting rod 6, a moving frame 61, a guide plate 62, a bottom plate 63 and a cylinder group 64. Several symmetrical connecting rods 6 are hinged on both sides of the bottom of the mounting base 1. The lower parts of the connecting rods 6 on both sides are hinged with a moving frame 61, and the outward side of the hinge at the lower part of the connecting rods 6 on both sides is connected to a guide plate 62. A number of guide grooves are provided on the guide plates 62 on both sides. The hinged parts on the outward side of the connecting rods 6 on both sides rotate and slide in the guide groove. The guide groove further enhances the function of the guide plate 62 to ensure that the connecting rod 6 can move smoothly along the set path. A bottom plate 63 is commonly provided between the bottoms of the guide plates 62 on both sides. The moving frame 61 is slidably provided in the middle of the bottom plate 63. It provides a support surface for the moving frame 61 and also serves as an installation platform for some components. A moving frame 61 is commonly provided on the inner side of the lower hinge of the connecting rods 6 on both sides. The moving frame 61 rotates with the connecting rods 6 on both sides. The guide plate 62 provides guidance for the connecting rods 6 to ensure the stability and accuracy of the moving frame 61 during movement. A cylinder group 64 is provided on the front side of the top of the bottom plate 63. The moving frame 61 can slide on the bottom plate 63 and adjust its position through the action of the cylinder group 64 to better adapt to the needs of different working environments. The piston rods of the cylinder group 64 are all connected to the front end of the rear moving frame 61. The cylinder group 64 drives the movement of the moving frame 61 to realize the rotation of the connecting rod 6 and the rise of the mounting base 1.
[0024] like Figure 1 and Figure 6 As shown, it also includes support legs 7 and telescopic rods 71. Support legs 7 are provided around the bottom of the base plate 63. The support legs 7 are used to assist in supporting the base plate 63 to improve stability. Telescopic rods 71 are provided at the diagonals around the top of the base plate 63. The telescopic ends of the telescopic rods 71 are connected to the bottom of the upper extension mounting seat 1. The telescopic rods 71 cooperate with the rotation of the connecting rod 6 to assist in adjusting the height of the mounting seat 1 to keep the mounting seat 1 stably rising.
[0025] When in use, the operator manually pulls the sliding frame 51 forward through the pull ring 56. At this time, the limit block 55 on the sliding frame 51 contacts the pulling piece 53 on the fixed frame 5, and the inclined part of the limit block 55 contacts the inclined part of the pulling piece 53, so that the pulling piece 53 is subjected to the pressure of the limit block 55 and compresses the spring 54. When the limit block 55 is completely stuck in the pulling piece 53, the spring 54 releases the pressure and the pulling piece 53 rebounds, thereby locking the position of the sliding frame 51. As the sliding frame 51 moves forward, the folding cover 52 unfolds and covers the conveyor belt 2, forming a closed space, which effectively prevents dust or material from leaking. When the height of the mounting base 1 and the conveyor belt 2 needs to be adjusted, the operator starts the cylinder group 64, and the piston rod of the cylinder group 64 extends to push the moving frame 6 1 moves backward, and the movement of the moving frame 61 causes the connecting rods 6 on both sides to rotate upward. Since the connecting rods 6 are hinged to the mounting base 1, they drive the mounting base 1 to rise. As the mounting base 1 rises, the telescopic rod 71 connected to the bottom of the mounting base 1 also extends to keep the mounting base 1 rising stably. When it is necessary to maintain the conveyor belt 2, the operator pulls the sliding frame 51 again to disengage the limit block 55 from the pulling member 53, and the spring 54 releases the pressure, and the sliding frame 51 is unlocked. The operator can easily move the sliding frame 51 through the pull ring 56 to perform necessary maintenance work, such as cleaning the conveyor belt 2 or checking the sealing condition. If more in-depth maintenance is required, the overall height of the conveyor can be adjusted through the cylinder group 64 to facilitate the staff to approach the conveyor belt 2 or perform other operations.
[0026] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
