What key parts should be paid attention to in the daily maintenance of vegetable transplanters

As an important mechanical equipment to improve the operation efficiency in modern agriculture, the long-term stable operation of the vegetable transplanter depends on scientific daily maintenance. Maintenance work can not only extend the service life of the equipment, but also ensure the quality of transplanting and reduce the failure rate.

Maintenance focus of the seedling mechanism
The seedling mechanism is one of the core components of the transplanter, responsible for accurately clamping or adsorbing seedlings. Any failure will directly affect the operation quality. The seedling parts such as the clamp, vacuum suction cup, and mechanical arm need to be regularly checked for lubrication and tightening.
The clamp structure is mostly made of metal or engineering plastics, which is prone to wear or deformation after long-term use. The spring tension and wear degree of the clamp need to be regularly tested. Lubricate the movable hinge of the clamp to maintain its flexibility and prevent rust and jamming.
The surface of the suction cup in the vacuum adsorption system should be kept clean, without damage and aging. The vacuum pump and pipeline system need to be regularly checked for air leakage and suction, and the filter should be replaced in time to ensure the stability of the negative pressure. The sealing performance of the vacuum valve directly affects the adsorption effect and needs to be maintained.
The mechanical arm and the drive device should be regularly filled with grease, and the fastening status of the connector should be checked to avoid looseness and abnormal vibration. Electrical components such as sensors and limit switches should be kept clean to prevent misoperation.

Maintenance points of the conveying system
The conveying system is responsible for stably conveying the removed seedlings to the planting position. Its smoothness directly affects the transplanting efficiency. Common conveying methods include chains, tracks and rollers, and each structure has different maintenance focuses.
Chain conveying should regularly clean the dirt and debris on the chain surface to prevent jamming. Use special lubricating oil to lubricate the chain to avoid dry grinding and accelerated wear. The chain tension should be moderate. Too loose will easily jump the chain, and too tight will easily increase the loss.
Pay attention to the wear of the track rubber surface and steel plate in the track conveying part, check the track tension regularly, and maintain the stability of the transmission system. The roller conveying bearing needs to be regularly oiled to prevent high temperature burning.
The conveying drive motor and reducer are also key maintenance objects. It is necessary to ensure that the lubricating oil is sufficient to avoid overload operation. The electrical terminal should be checked regularly to prevent poor contact and cause shutdown.

Maintenance and management of planting mechanism
The planting mechanism includes planting rods, depth adjustment devices and soil covering and compacting devices, which are the key links to ensure that seedlings are correctly planted in the soil. Mechanical contact with soil is very likely to cause wear and soil accumulation.
The surface smoothness and deformation of the planting rod should be checked regularly to keep it free of rust and cracks. The spring and linkage of the planting rod need to be lubricated regularly to ensure flexible and smooth movement. The threads and adjustment handles of the depth adjustment mechanism should be kept clean and oiled regularly to prevent jamming.
The soil covering device and the compacting wheel are prone to wear and soil accumulation due to direct contact with soil and stones. The residual soil on the soil covering device should be cleaned in time to prevent blockage and affect the uniformity of soil covering. The pressure wheel bearing should be kept lubricated, and the bearing wear should be checked regularly to prevent abnormal noise or jamming.

Maintenance of power system and hydraulic system
The power system generally refers to the engine and transmission of the tractor power input or self-propelled transplanter. The engine needs to replace the oil and filter element regularly according to the manufacturer's requirements, and check the cooling system and fuel system to prevent insufficient power or overheating.
The hydraulic system is mostly used to drive the gripper, planting rod and other components. The hydraulic oil should be replaced regularly, and the hydraulic oil tank should be kept clean and free of impurities. The hydraulic pipeline and joints need to be checked for leakage to ensure stable hydraulic pressure.
The piston rod of the hydraulic cylinder should be kept clean to prevent dust and impurities from damaging the sealing ring. The hydraulic system filter element and filter screen should be cleaned or replaced regularly to avoid hydraulic oil contamination.

Inspection and maintenance of electrical control system
The electrical system includes controllers, sensors, motors and wires and cables, which are the nerve center of the transplanter's automated operation. Check regularly whether the electrical connection is firm and whether the cable is worn or damaged.
The internal environment of the control box should be dry and clean to avoid moisture causing short circuits of components. Sensors and switches should be kept free of dust and functional tests should be performed regularly to ensure accurate signal transmission.
The motor and drive module need to monitor the operating temperature to prevent overload operation. Check the anti-corrosion treatment of the electrical connector regularly to improve system stability.

Cleaning and lubrication of the whole machine
The outside of the whole machine should be cleaned regularly, especially the dirt and residue in the working part should be cleaned in time to prevent affecting the mechanical movement and accelerating the wear of parts. When using a high-pressure water gun, be careful to avoid direct spraying of water onto electrical components and lubrication points.
Lubrication is the basic work to ensure the normal operation of the machine. According to the requirements of the equipment manual, regularly add lubricating oil or grease to each moving part, especially high-wear parts such as bearings, chains, gears, and slide rails.
Lubricants should be selected in appropriate models to avoid mechanical jamming or parts damage due to poor lubrication.
