First, the fuel economy of agricultural machinery
1. Reasonable selection of agricultural machinery and contiguous operations. Properly plan the field and driving routes to minimize idling, idling, roundabout, stopovers, shorten the total distance of the work, and reduce the inefficient energy consumption.
2. Regularly remove scale from the cooling system and grease and deposits from pipes and silencers.
3. After long-term use of the machine, there will be damage to the mat, loose screws, deformation or cracking of the duct, and aging of the seal ring will cause oil leakage. Therefore, it is necessary to take corresponding countermeasures to stop the fuel economy in time.
4. Keep the electrical system and starting mechanism in good condition. Do not idle the engine for a long time and stop immediately.
Second, the use of agricultural machinery and maintenance considerations
1. Battery maintenance is carried out according to the relevant regulations for long-term parking. It is regularly charged and discharged. The appearance is clean and dry. There is no copper rust on the terminal. The maintenance should be removed on the whole machine. Remove the battery ground wire in time. Conditions should be charged and discharged according to regulations to extend battery life.
2. All kinds of rust parts such as shells and thin iron parts should be touch-painted or fully painted and maintained without rust spots.
3. Eliminate the weeds, soil and other materials piled up outside the harvester in time to eliminate the rice straw, rice bran, rice grains and soil existing inside the machine.
4. Under the premise of cleaning, maintenance and restoration of technical performance of all agricultural machinery and equipment, it should be classified and discharged neatly when placed in storage, and placed reasonably. In the middle of the trailer, the front axle should be raised and the front wheel should be overhead; the front header of the self-propelled combine harvester should be flattened with wooden planks, and the grain of the threshing part should be cleaned to prevent the rats from drilling into the broken wires; Cover with a plastic sheet.
5. All parts of the rice harvester that must be lubricated should be filled with lubricating oil in time to reduce friction, reduce the power consumption of the harvester, improve the reliability of the harvester, and extend the life of the harvester.
6. Replace the parts with sick operation in time, repair the broken parts of the support plate and the support frame, and ensure the technical integrity of the mechanical skeleton. The rust block of the external equipment should be stored after painting. According to the maintenance requirements, add grease to the agricultural machinery to be operated, tighten the loose bolts, check whether the parts are missing, and replace the missing parts in time.
7. The harvester must check the tightness of the V-belt before working. If it is too loose or too tight, it will affect the life of the harvester. If the V-belt is too loose, it will cause slippage and the work efficiency will decrease. If the V-belt is too tight, it will increase bearing wear, increase power consumption, and may cause the shaft to be bent.
8. The harvester must check the tightness of the sprocket before working. It is too tight and easy to wear. The too loose chain will jump and even jump and the chain will fall off.
Third, agricultural machinery parts cleaning method
Agricultural machinery parts play an important role in the operation of the entire agricultural machinery.
However, different cleaning methods should be adopted for agricultural machinery parts with different materials and different precisions.
1, remove oil stains
(1) Degrease with aluminum alloy cleaning solution.
Because the alkali solution has a strong corrosive effect on the aluminum alloy, and the organic solvent is expensive, when the aluminum alloy parts need to be repaired, the aluminum alloy cleaning liquid can be disposed for cleaning. Generally, sodium silicate or sodium carbonate solution is added with a small amount of potassium dichromate to prepare, and the best cleaning effect can be obtained by heating to 60-70 °C.
(2) Degreasing with an organic solvent.
In order to prevent the strong corrosion of the alkaline solution on precision parts (such as high-pressure oil pump, fuel injector, etc.), organic solvents such as gasoline, kerosene, diesel oil, alcohol, etc. can be generally used to clean such parts, and generally no heating is required.
(3) Degrease with an alkaline solution.
For the removal of animal and vegetable oils and mineral oil on the surface of steel parts, a small amount of emulsifier may be added to the alkaline solution and washed after heating. If pressure injection is used, the degreasing effect is better. After cleaning, apply hot water spray to rinse off the residual alkali solution on the surface of the part.
2, remove carbon deposits
(1) Mechanical methods generally use metal brushes, blades and broken piston rings to remove carbon deposits. However, because this method is easy to scratch the surface of the part, it is not necessary to use abrasive cloth and steel scraper to remove the carbon deposit on the precision part. It can be removed by wooden, bamboo or copper scraper, or it can be rubbed back and forth on the cork board. .
(2) Chemical method
Place the part in the prepared chemical solution, dip it for a period of time, soften the carbon deposit, then remove the part, wipe off the carbon deposit with a brush or cotton thread, wash it with hot water and let it dry.
3, remove scale
(1) A solution of caustic soda (caustic soda) is used.
When removing scale with silicate as the main component, add 2% to 3% of the caustic soda aqueous solution to the cooling system. After the standby car is driven for 1-2 days, release it, rinse with water, then repeat it again, and finally rinse thoroughly with water. Clean the cooling system.
(2) using hydrochloric acid.
When removing the scale of the cast iron cylinder block, etc., the hydrochloric acid having a concentration of 8% to 10% and the solution of the butyl corrosion inhibitor equal to 3% of the hydrochloric acid may be heated to 50 to 60 ° C into the water jacket, and after immersion for 2 to 3 hours. The mixture is discharged, washed with an aqueous solution containing potassium dichromate, or injected into a water jacket with a 5% aqueous solution of caustic soda to neutralize the residual acid solution. Then rinse with water several times until it is clean. This method is suitable for removing scales whose main components are calcium carbonate and calcium sulfate.
Sunflower is a well known oily plant, that when it begins to pollinate presents a very important bee pasture. Sunflower flowers give bees during favorable year abundance of nectar and pollen powder. It blooms in the beginning of July and lasts for 20 days, and in areas where there are differences in planting time it can prolong the pasture up to a month. Nectar is mostly secreted during warm days and with morning dews at a temperature of 24-30 C. On a single plant there can be up to 1.500 flowers of which the first ones produce most nectar. That it is good to move the bees right before blooming. On all types of soil it does not pollinate equally, depending on the type of seed. Under favorable conditions strong bee communities can produce up to 30 kg and more.
Sunflower Honey is highly ranked in the world. The biggest manufacturers are France and Spain. Only pure honeydew and certain special homogenous types of honey are before it regarding quality. The reason is extremely high concentration of flower pollen and some minerals dissolved in sunflower honey. Its color varies from yellow to orange. It has a pleasant taste. People unjustly avoid it due to its fast crystallizing property. Consuming crystallized honey is very useful because by long-lasting melting of crystals of honey through sub-tongue glands all beneficial substances, by a shortest way possible, are introduced in the organism.
Consummation of honey in countries of Far East in the last decades has greatly increased. Great credit for that goes to schools in Japan and China that introduced for their students a mandatory honey consummation. It should be added that out of total sold amount of honey, sunflower honey is in the first place. As far as SAD and Canada, due to transition to hybrid types, sunflower is entirely lost. It is present only in southern parts where due to good weather there are conditions for growing it, and with for producing sunflower honey.
crystallization occurs after two months, so for those that are bothered by this, it is recommended to place the jar with sunflower honey in a container with warm water of 45 degrees. Sunflower honey has a pleasant taste and smell. Specific structure of sunflower makes this honey recognizable. Sunflower honey contains enzymes, minerals, organic acids, vitamins
