Operation of wheat combine harvester under “special†conditions
1. Windy weather operation The unit should not drive in the wind direction, in case the unit can not work normally; the air inlet on the windward side of the grain clearing mechanism should be adjusted to be small, and the air inlet on the leeward side should be adjusted to reduce the loss of the grain blowing belt and improve the quality of the grain. 2. Slope operation Try to avoid cross-slope driving; when harvesting long-distance uphill, increase the rear of the sieve, use a larger sieve hole, and reduce the opening of the air inlet to reduce food loss; Adjustment; when harvesting long distances on a downhill slope, the rear of the sieve should be lowered. 3. Wet field operation When the harvester is operating low, the harvester running device should be converted into crawler or half track type to harvest crops in time; when the mud foot depth is large, increase the ground wheel width of the unit to enhance the anti-skid ability and maximize grounding. Area to prevent the machine from sinking. 4. Bucket crop operation Appropriately reduce the forward speed of the unit; correctly select the unit's harvesting direction, the unit's forward direction should be opposite to the crop lodging direction (called reverse cut), or 45 with the lodging crop. The angle between the left and right (called side cut); adjust the reel forward and downward as appropriate to ensure smooth and normal cutting. 5. Low crop operation Appropriate adjustment and modification of the header and reel, the height of the header should be adjusted to keep the cutting height not higher than 15 cm and the cutter does not eat soil. If the cutting is too low, the cutter will accelerate the cutting of the knife. If the tooth is broken and damaged, the reel will be adjusted downwards and backwards for normal harvesting; the forward speed of the unit will be increased to ensure the normal threshing feed; and the harvesting operation in the direction of the seeding can reduce the increase of the forward speed. The unit is strongly vibrating and also reduces harvest losses. 6. Dry and over-ripe crop operations Adding a canvas strip on the wooden tumbling plate to increase the cushioning effect of the reel in the plucking, reduce the loss of the granules; reduce the height of the reel, so that the reel does not hit the head of the crop to reduce Granules; reduce the reel speed to reduce the number of hits on the cut crop.
Rib Locking Plate System is suitable for the fixation of rib fractures,which includes rib locking plate,rib locking screw and rib plate.
Ribs are structures throughout the thoracic cavity that protect vital organs such as the lungs, heart, and liver.The human body has 12 symmetrical pairs of ribs.
Where did the fracture occur?
Rib fractures are more common in adults. Fractures of one or more ribs may occur, and multiple fractures of the same rib may occur. The first to third ribs are shorter, protected by the scapula, clavicle, and upper arm, and are generally less prone to injury, while the floating ribs are more elastic and less prone to fracture. Fractures usually occur in four to seven ribs.
What is the cause of the fracture?
1. Direct violence. Fractures occur where violence directly affects them. They are usually cross-sectional or comminuted. Fracture fragments are often displaced inward and easily penetrate into the lungs, causing pneumothorax and hemothorax.
2. Indirect violence, chest is squeezed back and forth, fractures often occur near the axillary midline. The end of the fracture protruded outwards, which easily punctured the skin and caused open fractures, such as collapse or improper exertion during external cardiac massage. There have also been cases of posterior rib fractures due to violent blows to the anterior chest, or anterior rib fractures due to blows to the posterior chest. Most of the fractures were oblique.
3. Mix violence and others.
What type does fracture have?
1. Simple fracture
2. Incomplete fracture: mostly crack or green branch fracture
3. Complete fracture: most of them are transverse, oblique or comminuted
4. Multiple fractures: one bone and two fractures, multiple rib fractures
5. Open fracture: mostly caused by indirect violence or firearm injury
What are the complications of sternal fracture?
1. Abnormal breathing 2. Pneumothorax 3. Hemothorax
