Rotary cultivators are cultivating machines that are used to complete ploughing and hoeing operations with tractors. It has been widely used because of its characteristics of strong soil and flat surface after cultivation. The correct use and maintenance of rotary cultivators is particularly important for maintaining good technical conditions and ensuring the quality of tillage. Use correctly 1. Start. To join the power in the ascending state, the crew can start after the rotary tiller reaches the predetermined speed. Should try to slow down as slow as possible, this can guarantee the quality of the work, make the piece of soil crush, but also can reduce the wear and tear of the machine. Pay attention to listening to whether the rotavator has noise or metal knocking noise, and observe the smashed soil and the depth of cultivation. If there is any abnormality, the engine should be turned off immediately to ensure personal safety before checking. You can continue working after troubleshooting. 2. Turn. When turning in the ground, the operation is prohibited. The rotary cultivator should be lifted to remove the blade from the ground and reduce the throttle of the tractor so as not to damage the blade. The tail wheel and the steering clutch must cooperate with each other and proceed slowly. It is forbidden to make a sharp turn to prevent damage to the relevant parts. When raising the rotary cultivator, the tilt angle of the universal joint operation should be less than 30. When it is too large, there will be impact noise, which will cause premature wear or damage. 3. Reverse, transfer. When reversing, passing fields and transferring plots, the rotary cultivator should be raised to its highest position and power should be cut off. So as not to damage the parts. If you move to a distant place, use a locking device to secure the rotary cultivator. Troubleshooting 1. Rotary cultivator overload. Excessive cultivation, soil heavy and hard. Remedy: Reduce the depth of cultivation, reduce the unit forward speed and the speed of the coulter. 2. When the rotary tiller works, it will beat. Caused by soil hardness or blade mounting incorrectly. Remedy: Reduce the unit forward speed and coulter speed, and install the blade correctly. 3. Roughly undulating ground. The reason is that the forward speed of the unit is not properly matched with the speed of the cutter shaft. Remedy: Adjust the speed between the two appropriately. 4. There is a metal knock when the rotary tiller is working. The main reasons are: after the transmission chain is loosened, it collides with the transmission case; the blade, left arm or transmission case on both sides of the coulter shaft collide with each other; the fixing screws of the blade are loosened. Remedy: Adjust the tension of the drive chain, correct or replace severely deformed parts, and tighten the release screws. 5. Coulter gearbox noise. It is caused by the presence of foreign matter on installation or damage to bearings or gear teeth. Remedy: Try to remove foreign objects or replace bearings or gears. 6. Rotary tiller throws large clods. The main reasons are: blade bending deformation, broken blades, missing or severe wear. Remedy: Correct or replace the blade. 7. Rotary cultivator coulter shaft does not move. The main reasons are: gear or bearing bite; left arm or transmission box deformation, coulter shaft bending deformation; broken chain drive chain or the coulter shaft around the mud blocking the serious. Remedy: Correct, repair or replace severely deformed or damaged parts and clear the mud of the wrapped grass. The scientific maintenance of “prevention over treatment and raising of weight†is the principle of the use and maintenance of rotary cultivators. The maintenance of rotary cultivators is divided into on-duty maintenance and quarterly maintenance. 1. On-duty maintenance Under normal circumstances, class maintenance should be performed after each shift. The contents include: 1 Check the tightening of the bolts; 2 Check whether the consumables such as the machete, bolt and split pin are defective. If any, replace them. ;3 Check if the gear box, universal joints and bearings are short of oil. 2. Quarterly Maintenance After completion of each operation quarter, maintenance should be carried out, including: (1) Completely remove dust and oil on the equipment; (2) Replace oil and grease; (3) Check whether the blades are excessively worn, and replace the new blades if necessary; Check the hood, pallets and other deformation, if necessary, restore its original shape or renew; 5 comprehensively inspect the appearance of the equipment, add paint, oil rust prevention on the machete, spline shaft; 6 long-term when not in use, the wheel The tractor equipped with a rotary cultivator shall be placed on a level ground and shall not be hung on the tractor for a long time, so as not to cause deformation of the connected components.
The human tongue has a range of specific taste sensation neural receptors called taste receptors which are organized mainly as papillae on the tongue. When stimulated by chemicals, natural or synthetic, organic or inorganic, cations or anions, the receptors send signals to the brain which interprets the stimulations as sweet, bitter, sour, salty, and savory (unami, meaty taste). For examples, cations such as Na+ present in the table salt evoke the salty taste, and H+ presents in acids evokes a sour taste. Organic compounds such as sugars, dextrins and glycerol result in sweet taste, glutamate results in savory taste, while many toxic compounds such as nicotine, morphine, caffeine, quinine, etc. result in bitter taste. The sensation of tastes is an evolution trait for defense against poisons (normally evoke bitter taste), and for allowance of nutrients intake (normally evoke sweet or savory taste).
Sugar is a natural sweetener as well as a nutrient consumed in vast quantity around the world. It is one of the major calorie intakes by humans. Over consumption of sugar often leads to obesity and other related medical conditions. High blood sugar level (hyperglycemia) is a manifestation of the disease diabetic mellitus; if not managed properly, it could lead to a range of medical complications. To combat these medical conditions, high potency sweeteners with no calorie or low calorie intake are often being used to substitute sugar. Proper control of calorie intake, coupled with the use of these sugar substitutes has been very effective in managing the medical conditions.
Besides the medical indications, using sugar substitutes brings the economic benefit of lowering the cost of many foods and consumer products, from soft drinks to cakes, pasties, and even toothpastes.
A variety of chemical compounds, natural or synthetic, can evoke sweet taste, but not all of them are safe (for example lead acetate has a sweet taste but it is extremely toxic), nor are sweet taste specific (for examples, many of synthetic sweeteners can also evoke other senses of taste such as bitterness or metallic sensation). Therefore, selection of the right sweetener for a specific use depends not only on the cost, but also more importantly on the health and safety, the sweetening potency, the effectiveness under various physical conditions such as cooking temperature (heat stability) and pH, as well as other unwanted tense of tastes of the sweetener.
