In the four forms of belt conveyor covers, the fixed cover and the open and closed cover are made of galvanized corrugated steel plate or color coated steel plate. Generally, there are 9 fixed covers and 1 open and closed covers in every 10 covers, and the two covers can also be arranged alternately. The rain cover from one end of the frame to the other end of the "product" font installation, installation on the rain cover is strictly prohibited, do not force impact or knock. During installation, the closed cover is pressed on the left and right two adjacent fixed covers, and the coincidence length is one wave distance or two wave distances. Note that the hinged side of the closed and open cover is placed on the non-passing side of the conveyor, while the locked side is placed on the passing side of the conveyor. The folding point cover is only used at the folding point of the convex arc of the conveyor, while the deviation switch cover is designed to cover the deviation switch. Both are mounted on stationary covers. The frame of the fixed conveyor housing is the connecting Angle steel or Z-type steel, the length of which is equal to the installation length of the conveyor housing. Weld the connecting Angle steel or Z-type steel to the channel steel or small Angle steel on both sides of the conveying frame. The rain cover is fixed on the connecting Angle steel or Z-type steel with self-tapping nails, and there are no fewer than 4 fixed points per piece. If you need to install the supporting Angle, weld the supporting Angle to both sides of the frame, and then weld the connecting Angle or Z-type steel to the supporting Angle. Every 10 pieces can also be installed 1 piece of observation type rain cover, convenient maintenance and view.
belt conveyor covers is made of color steel plate. Color steel plate coating is a product of cold rolled steel plate, galvanized steel plate, coated (roll coated) or composite film (PVC film, etc.) after chemical treatment on the surface, and then baked and cured. Some people also call this product "roll coated steel plate", "plastic color steel plate". Rain cover is also known as rain cover, color steel rain cover, belt conveyor covers, conveyor dust cover, belt machine rain cover, etc. Rainproof cover plays a role in goods and environment. When goods are transported, it can reduce the loss and waste of goods, so that the conveyor belt is more stable in the transportation process. Secondly, it also extends the service life of the conveyor.
How much do you know about the production process of color steel belt conveyor covers, rain cover is made of color steel plate, its protection of the conveyor belt, reduce the waste of material in the transmission process, prolong the service life of the conveyor, for the conveyor protective cover, also belongs to the standard products. Rain cover has fixed, open and with observation window, you can see the material in the transmission process and the conveyor belt operation is normal, more run off cover, for the conveyor with a run off switch to play the role of rain, dust, etc.
Main characteristics of conveyor
The direction is changeable, and the conveying direction can be changed flexibly, when it can reach 180 degrees;
Conveyor telescopic freely, a unit of longer and short state ratio can reach 3 times.
Conveyor, each unit is composed of 8 rollers, each unit can be used immediately, also can be connected with multiple units, easy to install;
Color steel belt conveyor covers can be divided into indoor and outdoor two types, indoor color steel rain cover is mainly used to prevent dust, and outdoor use of color steel rain cover in addition to dust, more is to protect the operation and stability of equipment in harsh environment. So the outdoor rain cover not only on its structural performance requirements are very strict, but also need to have, wiper, spray, heating, cooling and other functions, so the price of outdoor color steel rain cover is far higher than the price of indoor rain cover.
By understanding the difference between indoor and outdoor color steel rainproof cover, we can compare ourselves to choose the right products, rainproof cover for goods, environment plays a very important role in helping, not only can reduce the loss of goods, but also can prolong the service life of equipment in disguise, so in the purchase of the corresponding to be treated carefully.

The main reasons for the failure of conveyor driving motor:
A screw conveyor conveying material with hard material or small iron, stuck reamer, current surge, burned motor.
2. The incoming material is too large, and the motor is burned by heat due to overload.
Treatment method:
1. Prevent small iron blocks from entering and keep the gap between the reamer and the housing.
2. Feed evenly and finish the material before shutdown.
Screw conveyor housing sloshing
Main reason: screw conveyor installation of each screw center line of different heart, when running eccentric rub shell, shell shaking.
Solution: Reinstall the correct center line.
Routine management and maintenance are not in place
1. Effective motor lubrication. Motor bearings and other rotating parts are not regularly lubricated, or the quality of lubricating grease is not qualified, or the grease does not penetrate into the lubrication effect is poor, will cause excessive wear of motor bearings, and even cause overheating of rotor friction stator.
2. Other reasons. Motor air duct blockage, poor cooling effect, the accumulation of water vapor inside the motor will damage the service life of the motor. At the same time, in the aspect of daily management, regular maintenance, demolition and inspection, well maintenance mechanism is not implemented in place, daily inspection floating in form, lack of convenient inspection and maintenance equipment, mechanical and electrical repair personnel quality is poor, low technical level, and motor frequent burn maintenance, more models and chaos, management disorder are the causes of motor frequent burn.
3. The motor is not equipped with sealing device or sealing effect, so that the motor underground is affected by moisture. The underground environment of coal mine is wet, and the roof gushing water is common. The humid air environment itself will reduce the service life of the motor. In addition, if the motor surface and shaft connection are not tight, the internal water of the motor will cause circuit failure and damage the internal components of the motor.
