Protective frame for belt conveyor

Abstract

The utility model discloses a protective frame for a belt conveyor, which relates to the technical field of belt conveyor equipment and comprises a protective plate, and an anti-jamming mechanism is mounted on the inner wall of the protective plate. Due to the fact that the anti-jamming mechanism and the rotating wheels are distributed in the rectangular array mode with the central axis of the protection plate as the center, when the device is used, due to the fact that goods are irregular in shape, the goods are prone to being jammed at the edge of a belt conveyor in the transportation process, and conveying of follow-up goods is blocked. Cargos are prevented from being stopped, and the transportation efficiency is improved; due to the fact that the connecting mechanisms, the connecting sleeves and the connecting shafts are connected in a clamping mode, when the device is used, most of traditional belt conveyor protection frames are integrally welded, heavy, long and inconvenient to install, and the protection plates are assembled through the connecting sleeves and the connecting shafts in an inserted mode and fixed through the fixing sleeves in a threaded mode, installation is convenient and fast, and transportation is convenient. The practicability of the device is improved.

Description

Technical Field

[0002] Belt conveyor is the abbreviation of belt conveyor, which is available in fixed and mobile types, with simple structure and high efficiency. In fixed belt conveyors, protective frames are required to be installed on both sides of the belt conveyor to intercept and protect the conveyed goods and prevent them from falling. However, when the existing belt conveyor protective frames are in use, they are easy to get stuck due to the irregular shape of the goods, causing conveying blockage and affecting the subsequent conveying efficiency. When conveying heavy goods, the goods hit the protective frames due to inertia, causing the protective frames to deform and damage. In addition, most of the existing protective frames are integrally welded, which is inconvenient to install. Therefore, a protective frame for a belt conveyor is needed.

[0003] The existing protective frame for belt conveyors has the problems of being unable to provide buffer protection, unable to prevent goods from getting stuck during transportation, and being inconvenient to install and disassemble when in operation. Therefore, a protective frame for belt conveyors is urgently needed. Utility Model Content

[0006] The side wall of the protective plate is installed with a connecting mechanism, which includes a connecting sleeve, a connecting shaft and a fixing sleeve. The side wall of the protective plate is installed with a connecting sleeve, the side wall of the protective plate away from the connecting sleeve is installed with a connecting shaft, and the outer wall of the connecting shaft is installed with a fixing sleeve.

[0007] The outer wall of the protective plate is installed with a buffer mechanism, and the buffer mechanism includes a limit shaft, a limit spring, a limit plate and a positioning rod. The outer wall of the protective plate is installed with a limit shaft, the outer wall of the limit shaft is installed with a limit spring, the outer wall of the limit shaft is installed with a limit plate, and the positioning rod runs through the interior of the limit plate.

[0012] 1. The utility model has an anti-stuck object mechanism, and the rotating wheels are arranged in a rectangular array with the central axis of the protective plate as the center. When the device is used, due to the irregular shape of the goods, it is easy to get stuck on the edge of the belt conveyor during transportation, blocking the subsequent transportation of goods. The setting of the rotating wheels makes the surface of the protective plate active, avoiding the jamming of goods and improving the transportation efficiency;

[0013] 2. The utility model has a connection mechanism, and the connection sleeve and the connection shaft are connected by snapping. When the device is used, the traditional belt conveyor protection frame is mostly welded as a whole, which is heavy, long, and inconvenient to install.

[0014] 3. The utility model provides a buffer mechanism, and the limit shaft forms a telescopic structure with the limit spring and the limit plate. When the device is in use, the limit plate is fixed to the outer wall of the belt conveyor through the positioning rod. When the belt conveyor is transporting heavy goods, the goods will hit the protective plate due to inertia, causing deformation and damage of the protective plate. The setting of the limit spring buffers and absorbs the force of the goods impact, avoiding deformation and damage of the protective plate, and reducing the cost of maintenance and replacement.
