Description

Technical Field

[0001] This invention relates to the field of variable frequency conveyor technology, and more specifically, to a variable frequency speed control conveyor. Background Technology

[0002] Conveyors, also known as conveyors, are suitable for horizontal, inclined, and vertical conveying of granular or powdery materials. The conveying distance varies depending on the model, generally ranging from 2 meters to 70 meters. Conveyors that can adjust their conveying speed according to different usage environments are called frequency converters.

[0003] In the prior art, a variable frequency speed control conveyor with Chinese patent application number 201911419299.3 includes a frame, on both sides of which conveyor rollers are movably mounted. A conveyor belt is connected between the two conveyor rollers via a frame drive. A servo motor is installed at the bottom inner side of the frame and is connected to the conveyor rollers via a transmission mechanism. A hollow roller is provided on the inner side of the frame, with a connecting shaft connected to one end of the hollow roller. A drive motor is installed on the front of the frame, and the output shaft of the speed control motor passes through the front of the frame and is connected to the connecting shaft via a coupling. A hollow rotating shaft is connected to the other end of the hollow roller. This variable frequency speed control conveyor effectively removes materials adhering to the surface of the conveyor belt and adjusts the friction according to different adhering substances on the conveyor belt surface, improving the applicability of the equipment and avoiding the phenomenon of unstable material slippage caused by caking. However, it cannot adjust the length of the conveyor belt according to the usage conditions, and needs to be replaced when transporting materials over long distances, increasing the operating cost of the conveyor.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0005] In view of the problems in the related technologies, the present invention proposes a variable frequency speed control conveyor to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by the present invention is as follows: A variable frequency speed control conveyor includes a frame, a first motor mounted on one side of the frame, a drive roller connected to the output shaft of the first motor, a speed regulating gear at one end of the drive roller, a driven roller connected to the drive roller via a chain, a conveyor belt on the outer sides of the drive roller and the driven roller, a mounting housing in the middle of the frame, an adjustable telescopic mechanism on the mounting housing, the adjustable telescopic mechanism including a second motor, a lead screw, a moving block, a mounting plate, a first hydraulic cylinder, a lifting frame, a pressure roller and a second hydraulic cylinder, and cleaning mechanisms on both sides of the bottom end of the frame, the cleaning mechanism including a connecting housing, a third motor, a rotating rod and a cleaning disc.

[0007] Preferably, the front side of the frame is provided with an inspection port, which is on the same side as the speed regulating gear of the drive roller.

[0008] Preferably, one end of the chain is connected to a speed regulating gear, the other end of the chain is connected to one end of the driven roller, and a speed regulating controller is provided on one side of the chain.

[0009] Preferably, the lead screw is disposed inside the mounting housing, one end of the lead screw is connected to the second motor, the second hydraulic cylinder is disposed at one end of the mounting housing, the moving block is connected to the lead screw, the bottom of the moving block passes through the mounting housing and is fixedly connected to the mounting plate, the first hydraulic cylinder is disposed on the mounting plate, the output end of the first hydraulic cylinder is connected to the lifting frame, and the pressure roller is disposed on the lifting frame.

[0010] Preferably, the pressure roller is rotatably connected to the lifting frame via a bearing, and the bottom of the pressure roller is in contact with the conveyor belt.

[0011] Preferably, the output end of the second hydraulic cylinder is connected to a positioning frame, and the second hydraulic cylinder is connected to the driven roller through the positioning frame.

[0012] Preferably, the connecting housing is fixed to the bottom of the frame, the third motor is installed on one side of the connecting housing, the output shaft of the third motor is connected to the rotating rod, and the cleaning disc is located on the outside of the rotating rod.

[0013] Preferably, the cleaning disc is attached to the surface of the conveyor belt, and a discharge pipe is provided at the bottom of the connecting housing.

[0014] The beneficial effects of this invention are as follows: With an adjustable telescopic mechanism, the length of the conveyor belt can be adjusted according to usage requirements, and the chain can be switched to achieve speed regulation of the conveyor, making it convenient to operate. With a cleaning mechanism, when the conveyor belt is conveying materials, the third motor drives the rotating rod and cleaning disc to rotate, which can rub and clean the surface of the conveyor belt, causing the debris on it to fall off, making it easy to clean the conveyor belt, which is convenient and practical. By incorporating a first hydraulic cylinder and a pressure roller, the lifting frame is moved by the first hydraulic cylinder when the conveyor belt is in use, causing the pressure roller to tighten the conveyor belt, preventing it from loosening and improving the conveyor belt's performance.
