Elevator and scraper conveyor formats. A conveyor is a material handling machine that continuously conveys materials on a certain line, also known as a continuous conveyor. The conveyer can carry out horizontal and inclined conveying, and also can form a space conveying line, and the conveying line is fixed. The conveyer has large conveying capacity and long conveying distance, and can complete a plurality of process operations simultaneously in the conveying process, so the application is very wide. Most of the existing conveyors are belt-type conveyors, namely, materials are placed on the conveyor belts, and the conveyor belts are driven to move by the rotation of the motors so as to be conveyed to corresponding heights or designated positions.

The belt conveyor develops towards high belt speed, large belt width, long distance and large conveying capacity, and the standard type spectrum only has one universal buffer carrier roller. The buffer carrier roller is an important part of a belt conveyor, the proportion of the manufacturing cost of the buffer carrier roller group in the whole belt conveyor is small, but the buffer carrier roller group plays a vital role in protecting the belt, and particularly on a receiving conveyor with large conveying capacity and large fall, particularly with block materials, the whole belt is always scrapped at high speed due to the fact that the buffer carrier roller is ineffective or the buffer effect is poor.

Due to the development of the technology, the conveying capacity is larger and larger, the blanking point is higher and higher, the impact force on the position of the buffer carrier roller is larger and larger, and the rigid connection of the traditional rigid connection buffer carrier roller cannot meet the requirement.

The second upright post 3 is inserted into the second limiting barrel 10, a second buffer spring 6 is connected between the second upright post 3 and the second limiting barrel 10, the top of the second buffer spring 6 is welded with the bottom of the second upright post 3, and the bottom of the second buffer spring 6 is welded with the bottom of the second limiting barrel 10. All rotate between first stand 2 and the second stand 3 that closes on and install limit roller 7, rotate between the second stand 3 and install well roller 8, limit roller 7 is the slope setting, and two 7 inclination angles of limit roller are the same to 7 axle heads of limit roller and 8 axle head clearance fit that close on, conveyer belt 11 has been laid jointly to 8 tops of limit roller 7 and well roller.

When specifically setting up, for the modularization dismouting of being convenient for, channel-section steel 13 is installed through the bolt in the top of crossbeam 1, and channel-section steel 13 top is fixed through welding and the spacing section of thick bamboo of first 9 and second 10. Because crossbeam 1 direct mount is usually on the conveyer track, if support the groove and need change the part, need take off crossbeam 1, it is too loaded down with trivial details like this, set up channel-section steel 13, can directly take off channel-section steel 13 from crossbeam 1, the simple operation, the dismouting of being convenient for.

The top of the second upright 3 is set in a circular arc shape, and the height of the top of the second upright 3 is kept consistent with that of the middle roller 8. If the top of the second upright post 3 is higher than the horizontal plane on which the shaft side of the middle roller 8 is located, the bottom of the conveying belt 11 is uneven, and local friction is increased; if the top of the second upright 3 is lower than the level of the shaft side of the middle roller 8, the contact of the bottom of the conveyor belt 11 is also affected.
