(hereinafter referred to as the hydroponic machine) is light and flexible, the style is 'beautiful, fuel efficient, one person can operate, is the latest product. The method of use and common troubleshooting methods are as follows: The fastening bolts should be tightened and the parts should be flexible and reliable. Then fix the clutch lever in the disengaged position, so that the clutch is in the disengaged state, then connect the V-belt pulley, use the low-speed pulley when cultivating the hard-field, and use the high-speed pulley when ploughing the foot.
11 to the appropriate position, after the diesel engine is running normally, when the hydroponic machine is working, the gear box should be checked frequently, and the oil leaks should be found in time. After the machine has been working for 2 days, check the gearbox. If there is water and dirt in the box, replace the seal between the gear oil pulley and the clutch in the gearbox. There should be enough calcium-based butter to maintain a good seal.
The engine of this machine is air-cooled diesel engine. It is strictly forbidden to pour cold water at high temperature to prevent the cylinder from rupturing. In the process of cultivation, if the screw is stuck in a stone or wrapped in weeds, it must be removed after the engine is turned off and stopped to prevent it from being emitted. Personal injury accident.
The new machine should be run-in before use. The oil in the gear box should be replaced after 50 hours of operation. After working for another 50 hours, the lubricant should be replaced again. In the future, change the lubricating oil once every 100 hours.
(8) After each shift is completed, the hydroponic machine must be cleaned to remove dirt such as mud and weeds. After the end of the annual farming season, the hydroponic machine should be thoroughly cleaned, wiped clean, coated with anti-rust oil and anti-rust paint, and stored in a dry place indoors to prevent sun and rain.
The clutch is not clear. The gap between the three separation levers on the clutch pressure plate and the end face of the separation bearing can be checked. If it does not meet the requirements, it should be adjusted according to the regulations.
The clutch slips. Check if there is oil or water entering the clutch and if it should be removed in time.
Oil leakage at the junction of the clutch shaft and the transmission case. If the rubber oil seal is damaged due to wear or improper installation of the rubber oil seal, replace the new one in time.
The hydroponic machine is back. Due to the incorrect installation of the spiral plow, the spiral plow must be re-installed correctly.
The water cultivator is turned off during the journey. Because the two spirals are stuck in the middle of the stone or wrapped in weeds, the stones or weeds should be removed after the flame is stopped. (Xue Zhicheng) value gear oil system 裘 4 old gold drop gear oil pump is widely used in the hydraulic system of agricultural machinery, the lubrication of the gear oil pump bushing is directly related to the service life of the pump, because the gear oil pump is working The bushing is subjected to a large radial load and is extremely easy to wear. Therefore, it is necessary to maintain good lubrication conditions, and the lubricating oil also has the functions of heat dissipation and grinding debris removal.
There are two kinds of lubrication methods for the general bushing: high-pressure throttling lubrication uses high-pressure oil to lubricate the bushing after throttling and depressurization. Usually, there is a figure-shaped throttle groove on the end face of the bushing, and the inner hole of the bushing is straight. groove.
Low-pressure oil lubrication uses low-pressure oil to lubricate the bushing. The lubricating oil groove is often opened on the suction chamber side of the sleeve end face, and the inner hole of the bushing is provided with a spiral groove.
The lubrication methods of several common gear pumps are shown in Table 1. Table 1 Common Gear Pump Lubrication Mode Gear Pump Type CB Type Three Series A Type H Mountain Bushing Lubrication Mode Low Pressure Oil High Pressure Throttle Low Pressure Oil Gear Pump No matter which lubrication is used In this way, the lubricated oil will return to the suction chamber to recycle the lubricant.
In use, we must be aware of the importance of gear pump bushing lubrication and the lubrication method of the pump used to avoid use failures. (Chen Yanshuang Sun Jiling) I is a rice throwing precision seeder developed by the Agricultural Engineering Research Institute of Jiangxi Academy of Agricultural Sciences. It is mainly used for rice sowing in the 561-point cultivating floppy disk, and can also be used for dry-bed breeding. sowing. It has the advantages of saving seeds, saving labor and improving the efficiency of planting. Since its promotion and use in our district, it has been well received by agricultural machinery technicians and farmers.
Check if the seeder is returned, that is, the upper and lower seeding disc holes should be covered with each other. c Grab a hand (about 200g). Dip the broken chest white grain. Place it in the seeding tray. Slightly tilt the seeding disc or use a light brush. Lightly brush the grain, fill the valley with each hole, and the excess swings back into the container of the seed valley.
Align the positioner of the seeder with the corner hole at one end of the mulberry floppy disk, press the return spring of the seeder with the right hand, and gently vibrate the surface of the seeder with the left hand. The seeding is dropped through the hole of the seeding disk and the hole of the cultivating floppy disk.
Lift the seeder, relax the return spring, and continue the seeding of the next nursery tray.
After the sowing, clean the seeder with water and place it in the room to prevent it from deforming.
(Liu Kaishun) The expansion technology requires the food extruder to be an ideal rich machine with less investment, quick effect and no risk. However, some people buy the machine and use it directly without knowing the operation technology. As a result, the machine will be damaged if it is not produced. Several technical points of operation are summarized for the user.
Before starting the machine, check whether the fasteners of each part are tightened, and note that the head bolts must be flattened and pressed.
Before processing, it should be turned on and idling for 1 line to preheat and check whether the operation is normal.
After preheating, you can add a small amount of wet rice slowly (just to mix the rice with the rice). When the puffed fruit is normal, immediately add a small amount of dry rice. At the beginning of processing, the temperature is low and the load is heavy. At this time, it must be added to the maximum throttle, and the rice should be slow. After the expansion is 60~70cm, gradually increase the amount of rice. It is advisable to increase the amount of rice to be powered.
Do not stop the machine in the middle of processing. Otherwise, the screw nut of the screw sleeve will cause sticking, the machine will not operate, and the disassembly is difficult. The feed port should not allow the puffed fruit and other impurities to enter, and the foreign matter should be removed immediately with a small wooden stick (no iron rods are allowed).
In the middle of processing, the export suddenly does not produce puffed fruit, which is caused by excessive moisture. The water vapor causes the rice to clump and block the outlet. At this point, the rice balls should be removed immediately with a small stick (no iron bars).
The reason why the puffed fruit has no side on one side is that the core is not properly placed, or there is a small stone in the rice to block the outlet. The amount of rice should be increased appropriately, or the taro on the core at the exit should be used from the non-expanded fruit. The direction is tapped in some direction.
Suddenly, the puffing fruit does not puff during the processing, which is caused by the excessive temperature of the fuselage. Cold water should be added to the front body of the head to lower the temperature.
After the processing is finished, let the machine idling 2~ coke, then loosen the nut of the nose to remove the core of the nut, remove the internal puff and re-assemble, and reassemble it for the next boot. During the disassembly process, it should be removed gently and gently, and must not be randomly collided, otherwise it will affect the assembly precision of each component and shorten the service life of the machine.
