The maintenance of the combine harvester is often limited by time, equipment and other conditions, and often require the maintenance personnel to work with the most simple means. Therefore, attention should be paid to the maintenance: (1) The riveting parts in the harvester such as the movable knife assembly Rivets are generally made by cold extrusion, and should not be heated when riveted. If heated, the material strength will be reduced. After riveting, the forming punch is used to strengthen the blade and the knife bar. (2) Vulnerable parts, especially pins, tabs, sleeves, and horns, cannot be replaced with butter and repairs during maintenance. For example, parts that wear out to the limit for a long time will cause a decrease in other mechanical life. short. (3) Axle type repair without balancing machine When repairing various shaft types to be balanced, a thrust bearing can be installed on one end of the shaft and clamped on the three claws of the lathe, and the other end can be used to withstand the top. If the lathe is short, it can be used. The center frame clamps the bearing mounted on the other end and corrects the balance. In the case of weights, tighten them with screws. Try not to use counterweights by electric welding. (4) Due to the large number of types of materials in maintenance, it is not easy to purchase, and can be used to process scrap shafts. At present, most shafts in China are based on 45# carbon steel. If quenching and tempering are required, under conditions of bad conditions, available oxygen can be used. The earth furnace heats the required parts into red and black water and put it in salt water, depending on the requirements. (5) It is very difficult to pull the oil trough in the sleeve hole because of refueling in certain parts of the harvester when processing sets of parts. Wherever it is difficult to add oil, butter and heavy oil can be used, except for nylon sleeves. Where nylon sleeves are used, it is best not to replace them with cast iron, copper or aluminum, because nylon sleeves do not deform under certain impact. (6) Keys and keyways on pulleys and shafts should be repaired to ensure that dimensions do not change ahead of time, and the size of the keys cannot be increased. Otherwise, the strength of the shaft will be affected. The keyways on the shaft can be welded in the opposite direction of the old keys by using a welding filler. To mill a keyway, the keyway on the pulley can be inlayed (transition fit) method. After inserting, use the countersunk screw to tap the key on the sleeve joint. (7) Maintenance of the hydraulic part of the harvester Remove the distributor and the flow reducing valve, etc., and press each pipe with the air pump. The hydraulic oil should be filtered and vented when it is re-installed. The assembly hydraulic repair is mainly the seal. The seal is best removed and replaced.
for the led waist heating belt, it uses 650nm+850nm wavelength combination. 650nm+850nm pain relief belt is a belt product with specific functions. It may use the physical therapy principle of red light or infrared to help relieve pain.
Such belts usually have the following characteristics and possible effects:
• Pain relief: Through the irradiation of light with a specific wavelength, it may help to accelerate local blood circulation and relieve pain and inflammation in the waist or other parts.
• Promote recovery: It may help muscle recovery and improve muscle elasticity.
• Easy to use: Generally small and light, rechargeable and portable, easy to carry, and can be used for physical therapy anytime and anywhere.
For Suyzeko portable red infrared light therapy belt:
About our portable red light infrared belt, it was developed and put on the market in 2015. Compared with ordinary LED waist heating belt, it has the following characteristics:
1. We use silicone material as the surface, compared with pvc material, our red light belt surface is softer and skin-friendly, it will not produce creases, wear-resistant and not easy to break. Whether you use it yourself or for your pet, it can fit perfectly and is easy to clean. You can clean it with a wet rag because it has waterproof properties.
2. We designed a frequency pulse light mode of 147hz 294hz 587hz 1174hz 4625hz cycle, and the treatment will stop automatically after 30 minutes. Compared with ordinary continuous wave treatment, it is more powerful.
3. We use oily circuit board, which can be folded 360 degrees. It can be used for pain therapy in various parts of the body, whether it is waist strain pain caused by long-term sitting in the office; stiff shoulder and neck fatigue; or arm, knee and other injuries caused by exercise, you can use the straps we give you to fix the red light pad to the part you need to treat.
4. We are equipped with a USB connection cable, which can be a good partner for your travel. You can use a mobile power supply to treat anytime and anywhere.
850nm and 660nm waves. These have been proven to: stimulate acupuncture points, increase blood circulation and help with antioxidant enzyme release. Phototherapy in this spectrum also promotes muscle relaxation and generally facilitates pain reduction, stimulates fibroblast and collagen production, increases lymphatic drainage, and reduces swelling, inflammation and bruising- bringing relief to athletes, sufferers of arthritis, and those with chronic pain.
The energy can flow through the body and interact with damaged cells in many parts of the body operating more like a vitamin that goes where it needs to go. This wavelength is also best for treating the lymph system and acupuncture points. Whereas studies show near-infrared wavelengths in the 850 nm penetrate deeper through skin and bone for relief of chronic pain.
As with red light therapy, near infrared light therapy does not mask the symptoms of pain, it encourages the healing of the actual cause of the pain. Once absorbed, the light energy kicks off a whole series of metabolic events, stimulating the body`s natural processes on a cellular level. There is an increase in blood flow, allowing the parts of the body to receive the oxygen and nutrients they need in order to function more effectively. Regeneration is stimulated. Inflammation and pain are reduced.

In many cases, after a course of treatment with red infrared light, the pain is gone.
