Maintenance points of small excavator rake

The small excavator rake plays an important role in many small earthworks, garden operations and farmland consolidation. In order to ensure its continuous and efficient operation and extend its service life, it is very important to master scientific and reasonable maintenance points. Next, we delve into the key links in the maintenance of small excavator harrows in daily use.

Exterior cleaning and debris removal

After each operation, the appearance of the small excavator rake should be cleaned in time, which is the basis of maintenance work. Use a high-pressure water gun or dedicated cleaning tools to remove dirt, rocks, weeds and other debris attached to the surface of the rake body to avoid accumulation of such debris on the rake body and affect subsequent operations. In particular, pay attention to cleaning the debris in the clearance of the rake teeth, "small excavator rake teeth cleaning points"

The material accumulated between the rake teeth will not only increase the wear of the rake teeth, but also change the working Angle of the rake teeth, reducing the efficiency of digging and crushing. Regular appearance cleaning enables operators to find out whether abnormal conditions such as wear and deformation exist on the surface of the rake body in time, which provides an intuitive basis for subsequent maintenance.

Rake tooth inspection and maintenance

The rake teeth are the key parts of the small excavator rake in direct contact with the material, and their status directly affects the operation effect. In daily maintenance, it is necessary to pay close attention to the wear degree of the rake teeth, which belongs to the category of "small excavator rake tooth maintenance method". Check whether the rake teeth are broken, loose phenomenon, if found that the rake teeth wear more than one-third of the original length, should be replaced in time. Because the excessive wear of the rake teeth not only reduces the digging ability, but also may fall off during the operation, causing safety hazards to equipment and personnel. At the same time, when installing the new rake teeth, it is necessary to ensure that it is firmly installed, and the fastening bolt torque meets the requirements of the equipment to ensure that the rake teeth work stably in high-intensity operations.

Lubrication of bearings and rotating parts

The bearing and rotating parts of the rake of small excavator are subjected to greater friction during operation, and good lubrication is the key to reduce wear and ensure smooth operation. According to the requirements of the equipment manual, the appropriate amount of grease is regularly added to each bearing and rotating joint, which involves the "maintenance skills of small excavator rake bearing". Before adding grease, clean impurities such as dust and oil on the surface of bearings and rotating parts to avoid mixing these impurities into the grease and reduce the lubrication effect. At the same time, check whether the oil seal is intact, if the oil seal is damaged, it should be replaced in time to prevent grease leakage, ensure that the bearing and rotating parts are always in a good lubrication state, extend their service life, and ensure the stable operation of the equipment.

Check the tightness of the connection

The connection between the rake body and the excavator and the connection between the various parts of the rake body are easy to loosen under frequent vibration and operation impact. Regular fastening inspection of these connection parts is an important part of maintenance work. Use an appropriate wrench to tighten the connection bolts according to the specified torque value to prevent the rake body from working unstable due to the loosening of bolts, and even the danger of parts falling off. This corresponds to the "Fastening points of the rake connection part of a small excavator". Especially after a long period of high-intensity operation or after bumpy road transportation, it is necessary to strengthen the inspection of the connection parts to ensure the overall structural integrity and safety of the equipment.

Hydraulic system maintenance

For small excavator harrows equipped with hydraulic drive, the normal operation of the hydraulic system is very important. Regularly check the oil level and oil quality of the hydraulic oil, if the hydraulic oil level is too low, the hydraulic oil that meets the requirements of the equipment should be added in time; If the hydraulic oil is found to be deteriorated, emulsified or mixed with impurities, it needs to be replaced immediately, which is "the key to the maintenance of the hydraulic system of the small excavator rake". At the same time, it is necessary to check whether the hydraulic tubing is damaged, aging, leakage, etc., if there is a problem, the tubing should be repaired or replaced in time. In addition, the filter of the hydraulic system is cleaned regularly to prevent impurities from entering the system and affecting the normal work of the hydraulic components, and to ensure that the hydraulic system can provide power support for the small excavator rake stably and efficiently.

The maintenance work of the mini excavator rake covers many aspects from the exterior to the key components inside. By doing a good job of appearance cleaning, rake tooth maintenance, bearing lubrication, connection parts fastening and hydraulic system maintenance, the small excavator rake can always maintain a good working condition, give full play to the best performance in various engineering operations, and provide solid guarantee for the smooth development of the project.
