Shandong Dongtai has long been producing wear-resistant guide troughs, belt guide troughs, and double-sealed polyurethane guide troughs.

After 1 o'clock in the morning on the same day, an old man dragging a thick iron chain on his foot was wandering at the gate of a community near the Martyrs' Tomb. People nearby saw it and immediately called the police.
When the Sha District police arrived at the scene, they saw many people surrounding an old woman asking questions with concern. An iron chain was tied to the old woman's right foot, and there was an iron lock at her ankle. While eating the noodles given by the noodle shop owner, the old woman answered questions from the people around her. Some people even stuffed Yuan cash into the old woman's pockets.
It turns out that the old woman has no mental illness, she just doesn’t know the road and often runs around. She has to take such measures as a last resort.
Problems with conveyor guide troughs
1. Introduction to conveyor guide troughs
Conveyors transport materials economically, reliably and safely, so they are widely used. Conveyors have many advantages such as simple structure, easy operation, large material transport capacity, high efficiency, strong continuity, easy automatic control, and convenient installation and maintenance. They have been used as the main transportation equipment in the coal industry. As an important part of this transportation equipment, the guide trough is designed to meet the needs of users, not only related to the normal operation of the conveyor, but also related to the economic benefits and costs of an enterprise. The material guide trough is an important auxiliary equipment for the material changing belt machine.
2. Problems with the conveyor guide trough
In the actual production of many projects, due to restrictions in many aspects such as site conditions, the wear resistance and sealing of the rubber sealing strips on the guide trough The effect is not very good over time. Theoretically, to make the belt machine run at low cost, many aspects must be paid attention to. First, the material must be properly added to the belt machine, and the belt machine must be completely unloaded. The most important thing is that the material should be loaded into the center of the conveyor belt, and the material should be loaded along the conveyor belt. The speed in the running direction of the conveyor belt should be as consistent as possible with the running speed of the conveyor belt. If the speed of adding materials is inconsistent with the speed of the conveyor belt, then there will be a large amount of material jumping at the feeding point, and it is likely to accumulate there. This kind of material jumping It is caused by the speed difference. In addition, some large particles of materials are easy to overlap, block and squeeze in the guide trough. In this way, not only the guide trough is damaged, but also the long-term stress life of the rollers under the belt will be shortened. reduce. In addition, due to many unpredictable factors at the production site, the tape splicing is incorrect, and the tape is easy to deviate and splatter. The belt conveyor is a heavy machine. The long-term vibration and extrusion during operation causes the guide trough to sink and its lower opening to expand, making the gap between the guide trough and the tape smaller and smaller. At this time, a section of the rubber baffle needs to be in contact with the tape. If the machine is in contact with the machine for a long time, the tape will be opened and there will be two scratches. Damage is also expected, and it needs to be shut down frequently for replacement.
3. Guide trough improvement plan
First look at the upper part of the guide trough. The upper part adopts a double-layer guide trough. Both layers of the guide trough are connected with the support frame angle steel with bolts, so that it can be easily disassembled and repaired in the future. , and the bolt holes are all long waist holes, which can be adjusted up, down, left, and right during installation. The lower part of the first layer guide trough is connected to the cover plate of the second layer guide trough. When making the cover plate, the holes can be opened first. , so that the cover plate can not only support the first layer of the guide trough, but also have a sealing function, and it also reduces the problem of vibration of the guide trough. In addition, a wear-resistant lining plate is installed inside the first layer of the guide trough, so that the life of the side plate will be greatly increased. Generally, when the material flow rushes from the upstream belt conveyor to the downstream belt conveyor, it will definitely contact the first layer of guide trough. At this time, when the material hits the liner, it will rebound to the inside of the second layer of guide trough. As you can imagine, this The material will not be so violent when it hits the guide trough for the second time, and will flow smoothly to the center of the belt conveyor, without causing the belt conveyor to deviate due to uneven force. Furthermore, due to the double guide material The trough adopts upper and lower side plates, so that the height of the side plates will not be very high, and the impact of the material will not cause the guide trough to sink and the lower opening to expand, so the deformation of each section of the guide trough will not be It will be very large, with almost no gaps and no spillage. Next, look at the second section of the guide trough. Its side plate adopts a double-bending structure, and then an extension plate is connected with bolts to reflect and concentrate the material toward the center of the tape. Since it is the second layer of the guide trough, The lateral impact force and load unevenness of the tape will be very small, so the deviation of the tape machine will be almost non-existent. The extension plate should generally be kept about a millimeter away from the tape during the design process, so that it does not come into contact with the tape. There is no friction, which reduces the resistance to the operation of the tape machine. Since the tape machine does not come into contact with the conveyor belt like the previous tape machine, the possibility of wearing the tape is almost impossible. It is conceivable that the life of the tape will also be improved. In addition, the addition of the extension plate also strengthens the strength of the bottom side plate of each section of the guide trough. In this way, the deformation of each section of the guide trough will be very small, the gap at the interface will be almost zero, and there will be no risk of material jamming. This may cause the material to be scraped outward or the tape to be punctured. In the same way, the connection between the second layer guide trough and the angle steel is also connected with a long waist hole, which is very useful both in assembly and later disassembly.
