Description

Technical Field

[0001] The utility model relates to the technical field of drum conveyors, in particular to a protective drum conveyor. Background Art

[0002] Drum conveyors are applicable to the conveyance of various types of boxed, bagged, palletized and other piece goods. Bulk materials, small items or irregular items need to be placed on pallets or turnover boxes for conveyance. They can convey materials with a very large single-piece weight or withstand relatively large impact loads. It is easy to connect and filter between drum lines, and multiple drum lines and other conveyors or special machines can be used to form a complex logistics conveying system to meet various technological requirements. Drum conveyors are suitable for conveying items with a flat bottom, and mainly consist of driving drums, racks, brackets, driving parts, etc. They have the characteristics of large conveying capacity, high speed, light operation, and can realize multi-variety co-line split-flow conveyance.

[0003] Drum conveyors are not only used for indoor item conveyance, but also widely used outdoors. However, when used outdoors, since the conveying rollers are generally directly installed on the mounting frame, they will still be exposed to the outside when the drum conveyor is idle, which easily damages the conveying rollers and other components, reducing the service life of the drum conveyor. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a protective drum conveyor.

[0005] The utility model is realized by adopting the following technical solutions: a protective drum conveyor, comprising a protection mechanism, a support mechanism and a fixing mechanism.

A conveying roller is fixedly connected to the surface of the rotating rod. Connecting blocks are fixedly connected to the front and rear sides of the mounting frame. A rotating shaft is rotatably connected to the middle of the connecting block. A protection plate is rotatably connected to the surface of the rotating shaft. Fixing rods are fixedly connected to the left and right sides of the protection plate. A connecting plate is rotatably connected to the surface of the fixing rod. A plugging rod is slidably connected to the middle of the connecting plate. Handles are fixedly connected to the front and rear sides of the mounting frame.

[0007] By means of the above technical solution, rotate the protection plates to make the two protection plates rotate on the surface of the rotating shaft. After the two protection plates come into contact, insert the plugging rod into the plugging holes of the protection plates, and the positions of the two protection plates can be fixed, thereby protecting the conveying rollers.

[0008] As a further improvement of the above solution, the mounting bracket is in a U-shape, a driving component is arranged on the back surface of the mounting bracket, a plurality of rotating rods are arranged, and the number of the conveying rollers corresponds to that of the rotating rods.

[0009] As a further improvement of the above solution, two protective plates are arranged, the two protective plates are in an L-shape, a pin hole is arranged in the middle of the protective plate, and the pin rod is located in the middle of the pin hole.

[0010] As a further improvement of the above solution, the supporting mechanism includes a support frame, the support frame is fixedly connected to the bottom end of the mounting bracket, a backing plate is fixedly connected to the bottom end of the support frame, a moving roller is fixedly connected to the bottom end of the backing plate, and a foot cup is slidably connected to the middle of the backing plate.

[0011] As a further improvement of the above solution, a threaded groove is arranged in the middle of the backing plate, a threaded rod is arranged at the top end of the foot cup, and the threaded groove and the threaded rod are adapted to each other.

[0012] As a further improvement of the above solution, the fixing mechanism includes a mounting block, the mounting block is fixedly connected to the side of the protective plate away from the mounting bracket, return springs are fixedly connected to the left and right sides of the mounting block, a limiting block is fixedly connected to the side of the return spring away from the mounting block, fixing bases are fixedly connected to the front and back sides of the mounting bracket, a through hole is arranged in the middle of the fixing base, and a pressing plate is slidably connected to the middle of the through hole.

[0013] Through the above technical solution, the pin rod is pulled out from the pin hole, and the two protective plates can be separated. After rotating a certain angle, the protective plate is pressed inward to make the limiting block slide into the through hole of the fixing base, and the position of the protective plate is fixed, improving the stability of the protective plate during use.

[0014] As a further improvement of the above solution, a sliding groove is arranged in the middle of the mounting block, the limiting block is located in the middle of the sliding groove, and the limiting block is clamped in the middle of the through hole.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] By arranging the protective plate, the roller conveyor is moved to the working place through the moving roller and fixed through the foot cup. When the roller conveyor is idle, the protective plate is rotated to make the two protective plates rotate on the surface of the rotating shaft. After the two protective plates come into contact, the pin rod is inserted into the pin hole of the protective plate. At the same time, the connecting plate slides on the surfaces of the pin rod and the fixed rod. When the pin rod is inserted into the pin hole, the positions of the two protective plates can be fixed, thereby protecting the conveying roller.

[0017] The utility model improves the stability of the protective plate during use by setting a fixed base. When the roller conveyor needs to be used, the bolt rod is pulled out from the bolt hole, and the two protective plates can be separated and rotated on the surface of the rotating shaft at the same time. After rotating a certain angle, the protective plate is pressed inward so that the limiting block slides into the through hole of the fixed base, and the return spring is compressed and contracted, fixing the position of the protective plate.
