With the continuous development of modern agriculture in China, the application of agricultural machinery technology in agricultural production activities is becoming increasingly widespread. The transmission belt is an important component of agricultural machinery, playing a role in driving various moving parts of the machinery. Once there is a problem with the transmission belt, it will cause the agricultural tractor to be unable to operate normally, which is not conducive to the smooth progress of agricultural production activities. This article analyzes the safe use and maintenance of transmission belts in the promotion of agricultural machinery technology, hoping to further improve the application efficiency of agricultural machinery in China through the analysis in this article.

During the use of agricultural machinery, it is necessary to pay special attention to the safe use and maintenance of transmission belts, in order to ensure the normal use of agricultural machinery and better complete agricultural production work. This article analyzes some common problems and precautions in the use of transmission belts in the promotion of agricultural machinery technology, and then proposes several effective suggestions for the maintenance of transmission belts, hoping to provide effective reference for farmers to use agricultural machinery.

1. Installation of transmission belt

In agricultural machinery, the transmission belt is an independent component that can output power, and the installation of the transmission belt can be selected according to the actual production needs. Although there are many types of agricultural machinery, the structure of the transmission belt used is roughly the same. Generally, for tractors above 15.7 kilowatts, at the standard engine speed, the circumference speed of the belt can be approximately (16 ± 1) meters per second, and the direction of the pulley can be changed according to demand.

The structure of general agricultural machinery is simple, and the installation and replacement of its transmission belt are also relatively simple. During the installation and replacement of the transmission belt, it is necessary to carefully observe the user manual of the agricultural machinery and the installation instructions of the transmission belt, and clarify the installation path and procedure of the belt. During the installation process, technicians need to follow the following method: Firstly, it is necessary to ensure that one end of the V-groove of the transmission belt can match the gear of the transmission wheel groove. The transmission belt is usually wrapped around the transmission wheel. Normally, if agricultural machinery only has one transmission wheel wound around the belt, then the center of this transmission wheel and the transmission wheel group are relatively close, and they are usually slotless transmission wheels. If during the installation of the drive belt, it is found that the installed drive belt exceeds the limit by too much or the length is not enough, the reason may be that the path around the drive wheel is incorrect. After the installation of the transmission belt is completed, it should be ensured that all belts are in the corresponding positions of the transmission wheel groove, and the transmission belt will not touch other components during the crossing process.

The following situations need to be noted during the installation of the transmission belt. Firstly, in the process of replacing the conveyor belt, the tension of the belt must be reduced to Z low in order to smoothly remove the belt. It is not allowed to use brute force to remove the belt under high tension, nor can non professional tools be used for forced removal. Before replacing the conveyor belt, it is necessary to disconnect the battery and check if the fan blades are rotating to avoid affecting the personal safety of the installation personnel. Before removing the old drive belt, calibrate the drive wheel to ensure the parallelism of the drive shaft, in order to prevent inaccurate position of the drive shaft from causing wear on the drive belt during operation and shortening its service life. In addition, the transmission belt of agricultural machinery transmits power through continuous friction between the belt and the pulley. It is necessary to set the tension of the belt correctly according to the manufacturer's regulations to avoid excessive or insufficient tension, which may cause belt wear. During the installation of the drive belt, it is necessary to first reduce the middle distance and gradually increase the center distance after the belt pulley is installed, to avoid using other tools to forcefully remove or insert the belt. Generally, drive belts in a group need to use drive belts of the same model and length to avoid wear caused by uneven force on the drive belts. In addition, during the installation process, staff need to take safety precautions to ensure their own safety.

2. Safety measures for the use of transmission belts

To ensure the safe use of agricultural machinery transmission belts, it is necessary to pay attention to the following precautions: first, choose the appropriate type of pulley and belt length according to the actual needs of agricultural production activities. Buy from reputable merchants. Secondly, because the raw material for the production of transmission belts is rubber, it is necessary to prevent the belts from coming into contact with acids, alkalis, and other substances during application to avoid corrosion and damage to the belts. During the installation and replacement of the belt, it is also necessary to wipe both hands clean to prevent them from getting greasy. If the belt is accidentally stained with grease, it should be considered to replace the belt. In addition, if agricultural machinery has not been used for a long time, the transmission belt should be loosened appropriately to avoid oil stains on the belt. The transmission belt should not be at too high a temperature during operation, and should be kept below 600 degrees as much as possible. The drive belt should be hung and stored properly when not in use, avoiding tangling, and placed in a cool and shady place.

3. Maintenance and upkeep of transmission belts

Firstly, it is necessary to regularly inspect the transmission belt of agricultural machinery to check its wear condition. If the belt is severely worn, it is easy for the belt to get stuck in the pulley, resulting in damage to the belt. If there are cracks or peeling on the surface of the belt, it is necessary to replace the belt immediately to prevent the belt from breaking. Secondly, it is necessary to check the looseness and breakage of the belt. If the above phenomena occur, the belt needs to be replaced immediately. Generally, if the engine is running normally, it is necessary to ensure that the transmission belt is replaced once a year. The degree of wear of transmission belts with different usage functions may also vary. If there are faults, cracks, or shiny side walls of the belt during use, replacement of the belt should be considered.

Attention should be paid to the tension of the transmission belt during use. If the belt is loose, it will accelerate the wear of the belt. If the belt is too tight, it will elongate the transmission belt and greatly shorten the service life of the bearing. It is necessary to set the belt tension reasonably according to the requirements. The force surface of a triangular belt can be divided into two sides during use. The two sides of the triangular transmission belt are wedge-shaped, and after wear, they will automatically move inward and need to be maintained on the original friction surface. When installing the pulley, the position deviation of the symmetrical center plane of the pulley groove in the same path should not exceed 0.3% of the center distance. A right angle can be used to check whether the adjustment is accurate.

In summary, in the promotion and use of agricultural machinery technology, it is necessary to pay special attention to the use and maintenance of transmission belts. The appropriate transmission belt model and length should be selected according to actual requirements, and the tension of the transmission should be reasonably set during installation and use to reduce belt wear and improve the effectiveness of the transmission belt, thereby ensuring the normal operation of agricultural machinery.
