What are the maintenance measures for the chain of two-row small hand-held rice transplanter

In the field of two-row small hand-held rice transplanter, chain maintenance is crucial and directly affects the operating efficiency and service life of the equipment. During the use of the chain, it is often disturbed by debris such as dirt, sand and plant residues. These substances will not only cause the wear of the chain to increase, but also affect its transmission efficiency. Therefore, cleaning the chain is the first step of maintenance and must be taken seriously.

It is necessary to thoroughly clean the chain before and after each use of the equipment. It is recommended to use appropriate tools such as soft brushes and sprayers to carefully remove dirt and debris from the surface of the chain. For more accumulated dirt, using a high-pressure water gun is an effective solution, but attention should be paid to the angle and intensity of the water flow to avoid water from penetrating into the chain, causing lubricant loss or accelerated corrosion. After cleaning, use a dry cloth to thoroughly wipe the surface of the chain to ensure that there is no residual water to avoid affecting the subsequent lubrication effect.

Chain lubrication is an indispensable core link in the maintenance process. The main function of lubricating oil is to reduce the friction between the chain and other components, prevent the high temperature generated by friction from damaging the chain, reduce the wear rate, and thus extend the service life of the chain. Regular addition of high-quality lubricant is essential for the chain of the Two-Row Small Hand-Held Rice Transplanter. When choosing lubricant, the appropriate type should be determined according to the workload, environmental conditions and frequency of use of the chain. Before lubrication, make sure the chain is clean, then apply lubricant evenly to ensure that it can penetrate into each section and form a good lubricating film. After application, manually rotate the chain to promote further penetration of the lubricant and improve the lubrication effect.

During the lubrication process, the operator needs to pay special attention to the amount of lubricant. Excessive or insufficient lubricant will have a negative impact on the normal operation of the chain. Too much lubricant may cause oil leakage, absorb dust and sand, and increase the wear of the chain; while insufficient lubricant cannot effectively reduce friction, causing the chain to overheat and increase wear. Therefore, it is crucial to maintain an appropriate amount of lubricant and regularly check the lubrication status of the chain to prevent chain failure due to improper lubrication.

In addition, the tension of the chain is also an important factor affecting its normal operation. Due to friction and stretching, the tension of the chain changes during use. Too loose or too tight will cause the chain to run poorly or even be damaged. Operators need to check the tension of the chain regularly to ensure that it remains within the standard range recommended by the manufacturer. A too loose chain is not only easy to fall off, but also reduces the transmission efficiency and even causes chain skipping; while an overly tight chain will increase the friction between other parts, increase power consumption, and cause premature wear. When checking, you can sense its tightness by manually pulling the chain, or use special tools to measure it. If the tension of the chain is found to be inappropriate, it should be adjusted in time to ensure the normal operation of the chain.
