Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and more specifically, to a small flatbed conveyor. Background Technology

[0002] As a type of mechanical conveying equipment, flatbed conveyors are widely used in industries such as logistics, machinery, electronics, chemicals, and metallurgy. With the increasing number of on-site equipment and the continuous compression of space, conveyors need to be miniaturized, lightweight, and cost-effective.

[0003] A search revealed that utility model patent CN212798387U discloses a small flat conveyor, including a conveying platform and a frame for mounting the conveying platform. The conveying platform includes a platform support body, and a drive shaft, a belt, and a driven shaft connected in sequence. The platform support body includes a tray, a drive shaft support block for mounting the drive shaft, and a driven shaft support block for mounting the driven shaft. Both the drive shaft support block and the driven shaft support block are mounted on the tray, and the tray is also provided with a hook. The frame includes a base and two mounting seats on the base. The mounting seats include two mounting plates and a hook that cooperates with the hook. The mounting plates are provided with pins that cooperate with the driven shaft support block or the drive shaft support block. This patent improves the structural compactness of the conveying platform by using drive shaft support blocks and driven shaft support blocks, and restricts the forward and backward displacement of the conveyor platform by using pins and restricts the up and down movement of the conveying platform by using hooks, thereby improving stability and facilitating disassembly and assembly, thus improving maintenance efficiency.

[0004] However, the above patents still have the following shortcomings: it is not convenient to adjust the height of the conveyor, and it is not convenient to adjust the conveying length of the conveyor. Therefore, we propose a small flat conveyor. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a small flat conveyor.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A small flat conveyor includes a base. Two sets of first hydraulic cylinders are fixedly installed on the top surface of the base. A crossbeam is fixedly connected to the top of each of the two sets of first hydraulic cylinders. Telescopic square grooves are respectively opened at both ends of the two crossbeams. Second hydraulic cylinders are fixedly installed in the inner cavities of each of the four telescopic square grooves. Telescopic support columns are fixedly connected to the output ends of each of the four second hydraulic cylinders. The ends of each of the four telescopic support columns extend to the outside of the crossbeams and are fixedly connected to a transmission seat. A drive roller is rotatably connected between each pair of transmission seats. Two tensioning mechanisms are provided on the base. A conveyor belt is driven between the two tensioning mechanisms and the two drive rollers. A drive motor is fixedly installed on the outside of one of the transmission seats. The output shaft of the drive motor is connected to one end of the drive roller shaft.

[0008] As a preferred embodiment of this utility model, the tensioning mechanism includes two third hydraulic cylinders fixedly installed on the top surface of the base. The top ends of the two third hydraulic cylinders are respectively fixedly connected to support seats. A pull roller is rotatably connected between the two support seats. The bottom surface of the pull roller is in contact with the inner surface of the conveyor belt.

[0009] As a preferred embodiment of this utility model, a control panel is fixedly installed at the bottom of one of the crossbars, and the control panel is electrically connected to the second hydraulic cylinder, the drive motor, the third hydraulic cylinder and the first hydraulic cylinder respectively.

[0010] As a preferred embodiment of this utility model, a storage battery is provided on the top surface of the base, and the storage battery is electrically connected to the second hydraulic cylinder, the drive motor, the control panel, the third hydraulic cylinder and the first hydraulic cylinder.

[0011] As a preferred embodiment of this utility model, the bottom surface of the base is fixedly equipped with multiple self-locking casters.

[0012] As a preferred embodiment of this utility model, a plurality of support rollers are rotatably connected between the two crossbeams, and the top surfaces of the plurality of support rollers are in contact with the inner surfaces of the conveyor belt.

[0013] In a preferred embodiment of this utility model, the inner wall of the telescopic square groove is in contact with the side of the telescopic support square column, and the side of the conveyor belt is in contact with the inner side of the cross frame, the transmission seat, and the support seat, respectively.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] In this invention, two sets of first hydraulic cylinders support two crossbeams. Simultaneously, the first hydraulic cylinders adjust the height of the drive rollers at both ends of the two crossbeams, thereby adjusting the height of the top surface of the conveyor belt and consequently the height of the conveyor. Four second hydraulic cylinders move four telescopic support columns closer or further apart, adjusting the distance between the two drive rollers and consequently the length of the conveyor belt fitted around the two drive rollers, thus adjusting the conveying length of the conveyor. Furthermore, a third hydraulic cylinder moves the support base and pull rollers downwards, which in turn pull the conveyor belt downwards, tautning the conveyor belt around the two drive rollers and two pull rollers, ensuring the conveyor belt can rotate and transport materials. This design is highly practical. Attached Figure Description
