Timely Maintenance and Repair of Agricultural Machinery After Wheat Harvest
Combine harvesters should be well maintained before heading to the field, so that they stay in good technical condition, run with fewer breakdowns, perform reliably, reduce faults, improve work efficiency, and extend service life. 1. Self-propelled combine harvesters (l) Add lubricating oil to each lubrication point daily as specified. (2) After a period of use, tighten the front wheel and rear wheel nuts; check and adjust the tension of all V-belts; check and adjust all drive chains; when the indicator light comes on, clean the dry air filter; clean the rotating wind hood and radiator; check the coolant level and top it up; check and clean the water collector; check the fuel filter, drain the accumulated water and sediment, clean the hydraulic oil tank filler port and check the oil level. Park the combine harvester on level ground, check the engine oil in the oil pan, and add oil as needed; tighten the grain unloading auger wire rope; clean the hydraulic drive oil tank filler port and check the oil level. If necessary, clean the cab filter. (3) After one quarter of use, replace the fuel filter element and replace the engine oil filter. Check the specific gravity of the battery electrolyte, and charge or top up with distilled water as needed. Check the coolant level and top it up. Clean the fuel transfer pump, check and adjust the traveling clutch clearance, check and adjust the foot brake, and adjust the hand brake cable.

Never neglect agricultural machinery maintenance after the wheat harvest
Before the combine harvester goes out to the field, service the machine well so that it stays in good technical condition. Then it will have fewer breakdowns in use, run stably, reduce failures, raise work efficiency and extend the machine's service life. 1. Self-propelled combine harvesters (l) Add lubricating oil to each lubrication point every day as specified. (2) After a period of use, tighten the front wheel and rear wheel nuts; check and adjust the tension of all V-belts; check and adjust all drive chains; when the indicator light comes on, clean the dry air filter; clean

Detailed Explanation of Tea Machine Installation Steps and Precautions
At present, the processing units for famous and high-quality tea in tea-producing areas are composed of individual machines. During installation, pay attention to the following: 1. Install the unit according to the tea-making process. For newly built factories, the number of machines, operating space and leaf-spreading area should be taken into account. For the general production line arrangement of machinery, the horizontal direction is arranged in vertical rows. 2. Select the knife switch and wire diameter according to the power load of the processing machinery. Protective measures should be taken for the passage lines, and a monitoring lamp should be installed on each phase of the distribution board to prevent operation with a broken phase. 3. Pay attention to the running direction of the machinery. If it is opposite to the specified direction, swapping any two of the three phases will

Introduction to the Performance Characteristics of the Long-Board Type Flat Tea Frying-Drying Machine
The long-board type flat tea frying-drying machine first appeared in the Xinchang tea area in 2000, and its manufacturers are mainly distributed in Xinchang and Pan'an counties. At present, this tea machine has been widely used in some main Longjing tea producing areas of this province. The commonly used models of the long-board type flat tea frying-drying machine are mainly composed of a long semicircular tea frying pan, a long tea-leaf stirring board, a transmission mechanism, a heat source device, a temperature control instrument and a frame, etc. When this machine is used for Longjing tea frying, like manual frying, it is also divided into two main processes: the green-frying pan and the final-firing pan. For frying the green-frying pan, when the pan temperature reaches

Detailed Explanation of Tea Machine Usage and Key Operating Points
In the mechanized processing of famous and high-quality tea, from the fixation of fresh leaves to the finished product, two relationships must be handled well: first, the relationship between heat and water vapor; second, the relationship between mechanical force and appearance. Heat causes biochemical changes in the tea leaves, while force applies external force to the tea leaves to cause changes in appearance. In specific use, attention should be paid to: 1. Before operation, each machine should be trial-run, and it should be observed whether the temperature and other technical parameters can meet the process requirements for famous and high-quality tea, such as the fixation time of fresh leaves, which is generally 1' to 1'10" for spring tea, 50" to 1' for summer tea, and for Maofeng tea, the drying
