Description

Technical Field

[0001] The utility model relates to the technical field of multi-section belt conveyors, in particular to a multi-section belt conveyor with integral transition and joint tensioning. Background Art

[0002] Belt conveyor is the abbreviation of belt conveyor, which is mainly used for horizontal or inclined conveying of bulk materials or finished items. Belt conveyor has the advantages of simple structure, stable and reliable operation, strong adaptability to materials and sites, large conveying capacity, low power consumption, etc. However, due to the strict restrictions of the country on the external dimensions (length, width, height) of equipment transported on roads, belt conveyors need to be folded to meet the needs of the actual transportation process. The existing multi-section folding belt conveyor uses a hydraulic cylinder with a crank or connecting rod mechanism to realize the folding action of the belt conveyor. Although this structure realizes the folding action of the belt conveyor, when the belt conveyor is working or transporting, the hydraulic cylinder needs to bear the weight of the folded section of the belt conveyor and the additional load caused by vibration, and it is impossible to achieve a close positioning connection between each segmented device, affecting the reliability and stability of the device.

[0003] In order to solve the above technical problems, the Chinese utility model patent with authorization announcement number CN214030721U discloses a multi-stage folding belt conveyor, which uses an external lifting device to rotate the left end of the folding frame on the left side around the frame clockwise, and rotate the folding frame on the right side around the frame counterclockwise, driving the corresponding T-shaped block to slide inside the T-shaped groove. At the same time, the relative inner sides of the two T-shaped blocks located in the same horizontal direction and adjacent to each other are connected to the connecting rod by pin rotation. Therefore, under the rotation of the folding frame, the folding work is carried out, so that the support blocks slide inside the corresponding slide grooves until the outer sides of the support blocks are tightly fitted with the corresponding inner walls of the slide grooves. At this time, the folding of the folding frame is completed, the length of the frame and the folding frame as a whole is reduced, which is convenient for personnel to carry and pack for loading, reduces the burden of personnel for disassembly and installation, and improves work efficiency.

[0004] Although the technical solution provided by the utility model solves the problem that the existing multi-section belt conveyor cannot achieve tight positioning and connection between each segmented device, the various belt conveyors in the multi-section belt conveyor line are independent of each other and do not form a whole. During the installation process, it is impossible to truly achieve uniformity of the conveying surface, and there will be a certain height difference. At the same time, the conveying belt of the belt conveyor may become loose after long-term use, resulting in unstable cargo transportation during the conveying process. Utility Model Content

[0005] The utility model aims to provide a multi-section belt conveyor with integral transition and joint tensioning to solve the problems raised in the above-mentioned background technology.

[0006] The present application embodiment adopts the following technical solutions:

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0020] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0021] See also Figure 1-4 , a multi-section belt conveyor with integral transition and joint tension; each section of the belt conveyor includes a conveying bed plate 1, a support leg 6 is fixedly installed at the bottom of the conveying bed plate 1, and a foot 7 is threadedly connected to the bottom end of the support leg 6. By providing the foot 7, the height of the conveying bed plate 1 can be slightly adjusted to ensure that the combined conveying bed plate 1 is in the same horizontal plane, and two adjacent conveying bed plates 1 are connected by a transition plate 2. Guide rollers 4 are installed at both ends of the conveying bed plate 1, and an intermediate guide roller 13 and a tensioning roller 12 with adjustable horizontal position are respectively installed in the middle of the conveying bed plate 1. A rotatable driving roller 11 is arranged below the conveying bed plate 1, and a conveying belt 15 is wrapped around the outer side of the guide roller 4 and the driving roller 11, and the outer side surfaces of the tensioning roller 12 and the intermediate guide roller 13 are in contact with the lower side surface of the conveying belt 15;

[0022] Two first bearing seats 3 are installed on the transition plate 2, the guide roller 4 is rotatably connected to the first bearing seat 3, and the tensioning roller 12 and the intermediate guide roller 13 are symmetrically distributed in the middle of the conveying bed plate 1;

[0023] The end of the tensioning roller 12 is rotatably connected with a connecting shaft, the side of the conveying bed plate 1 is fixedly connected with a horizontal mounting seat 16, the connecting shaft is slidably connected to the middle of the mounting seat 16, the middle of the mounting seat 16 is rotatably connected with a tensioning bolt 17, and the connecting shaft is threadedly connected to the outer side of the tensioning bolt 17;

[0024] A frame 8 is fixedly installed at the bottom of the conveying bed plate 1, a motor 10 is fixedly installed on the frame 8, a second bearing seat 9 is fixedly installed on the frame 8, the specific model of the second bearing seat 9 is BDJ206, a driving roller 11 is rotatably connected to the second bearing seat 9, and the motor 10 is transmission-connected to the driving roller 11 through a driving chain 14;

[0025] When the utility model is used, the staff first starts the motor 10, and the motor 10 and the driving chain 14 can drive the driving roller 11 to rotate, and the rotation of the driving roller 11 can drive the conveying belt 15 to transmit, so that the goods can be transported;

[0026] When the conveyor belt 15 becomes loose after long-term use, the staff can adjust the position of the tensioning roller 12 by tightening the tensioning bolt 17. By moving the tensioning roller 12 to the right, the conveyor belt 15 can always be in close contact with the guide roller 4, the driving roller 11, the tensioning roller 12 and the intermediate guide roller 13, thereby increasing the friction between the conveyor belt 15 and the multiple rollers, thereby ensuring that the material will be more stable during the conveying process. When the conveyor belt 15 is too tight, the tensioning bolt 17 can be turned to move the tensioning roller 12 to the left, thereby loosening the conveyor belt 15 to prevent the conveyor belt 15 from being too tight and breaking.
