Description

Technical Field

[0001] The utility model relates to the technical field of mineral mining equipment, in particular to a double-channel mineral processing conveyor device with quickly replaceable belts. Background Art

[0002] Conveyor belts are commonly used in mineral processing equipment to transport ore. As the conveyor belts cycle continuously, their surfaces are constantly scraped and worn by the ore. After a period of use, the conveyor belts need to be replaced. Replacing conveyor belts is often a cumbersome process, especially when the belts are too long, too wide, or heavy. This requires the use of large lifting equipment such as truck cranes or hoists to assist in disassembly and assembly, which is time-consuming and labor-intensive. Furthermore, some belt conveyors do not allow the belt to be completely removed, and even require the belt to be cut for removal. Similarly, the newly installed belt also needs to be reconnected at the broken end, which is a very labor-intensive process. Utility Model Content

[0003] The purpose of this utility model is to provide a dual-channel ore dressing conveyor with quickly replaceable belts. It has two parallel synchronous conveyor belts, which can realize the production of large-throughput ore conveying and screening. The two belts can be disassembled and assembled separately, and the process of disassembling and assembling the conveyor belts is simple and easy to operate, which can save equipment costs and improve equipment working efficiency.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0005] A dual-channel mineral processing conveyor with quickly replaceable belts. A conveyor belt is installed on a frame, and a driving shaft and a driven shaft are installed at both ends of the conveyor belt. The driving shaft is driven by a drive motor; the conveyor belt is divided into two left and right sections to form two transmission channels, and the two channels use the same driving shaft and driven shaft.

[0006] The structure of two parallel transmission belt channels can avoid the disadvantage of difficult disassembly and replacement brought about by the structure of a single wide transmission belt. When replacing the transmission belt, loosen the tensioning shaft and pull the belt out horizontally from the outside. The weight of a single transmission belt is limited and can be completed manually without lifting equipment, which improves the efficiency of equipment maintenance.

[0007] A tensioning mechanism is located below the center of each conveyor belt. The tensioning mechanism consists of two left and right idlers, with a belt tensioning shaft located between them. The idlers are mounted to the frame via an idler mounting plate, while the belt tensioning shaft is mounted to the frame via a tensioning shaft mounting plate. Each belt's tensioning mechanism operates independently. When the belt tensioning shaft is supported, the belt is tightened; when the belt tensioning shaft retracts, the belt is loosened for replacement. The design of the independent tensioning mechanisms allows each belt to be individually disassembled, assembled, and replaced.

[0008] The tensioning shaft mounting plate is provided with a long groove, the opening direction of the long groove is opposite to the movement direction of the conveyor belt, the lower end of the tensioning shaft mounting plate is provided with an opening, the opening direction is opposite to the movement direction of the conveyor belt, a tensioning screw is provided at the opening, the threaded portion of the tensioning screw is threadedly connected to the two end shaft extensions of the belt tensioning shaft, and the two end shaft extensions of the belt tensioning shaft are horizontally limited by the long groove.

[0009] When tension needs to be increased, the tensioning screw is turned, which pulls the belt tensioning shaft downward, generating greater tension. When the conveyor belt needs to be disassembled, the tensioning screw is turned, which pushes the belt tensioning shaft upward. Once the conveyor belt is loosened, the roller is removed from the roller mounting plate, and the conveyor belt can be completely disengaged by sliding it sideways.

[0010] The lower end of the roller mounting plate is provided with an open L-shaped opening groove, and the shaft of the roller is clamped in the L-shaped opening groove. The L-shaped opening groove facilitates the quick installation and removal of the roller, and does not require bolt tightening, and can be directly hung.

[0011] The lower middle part of the column of the frame is connected to the lower support plane composed of the lower cross beam and the lower longitudinal beam. The lower support plane is fixedly connected to the bottom end of the herringbone support. The top of the herringbone support supports the bottom of the conveyor belt frame. The conveyor belt frame is composed of the upper longitudinal beam and the upper cross beam. The driving shaft and the driven shaft are respectively installed at both ends of the conveyor belt frame.

[0012] The support points of the upper support plane are concentrated on the top of the herringbone support, and there is free space on both sides. The conveyor belt can be freely moved in and out and disassembled from both sides of the upper support plane to achieve rapid installation and removal of the belt.

[0013] 1. The utility model has two parallel synchronous conveyor belts, which can realize the production of large-throughput ore conveying and screening, and the two belts can be disassembled and assembled separately. While realizing large-throughput transmission, it will not increase the difficulty of belt replacement and there is no need to use lifting equipment for belt replacement.

[0014] 2. The utility model reserves free space for belt installation and removal on the side of the equipment, and the belt can be installed and removed from the side, which can avoid the tedious operation of cutting the belt and removing it, and is easy to operate.
