First, the operation process and technical requirements: 1. The harvesting of rapeseed machinery is divided into two stages: combined harvesting and staged harvesting. Rapeseed Machinery Combine Harvesting Harvesting, threshing, separation of stalks, rapeseed sifting and other operations of rapeseed can be performed by a combine harvester at one time. Harvesting of rapeseed machinery in the early stages of yellow rapeseed rape, cutting rapeseed by cutting machine or artificially, and placing rapeseed field and placing it in the field for 5-7 days. After the rapeseed is ripened and dried, it can be harvested, threshed, and stalked by the combine harvester. Stalk separation, rapeseed cleaning and other operations. 2. The joint harvesting process of rapeseed machinery is: crew preparation → field preparation → trial cutting → normal operation → unit maintenance → locomotive storage. The technical requirements are: the maturity of rapeseed reaches 85-90% for mechanical harvesting; the harvest should be harvested cleanly, without cutting, the cutting height is in line with local agronomic requirements, and the harvested stems should be broken and evenly spread in the field. 3. The harvesting operation process of rapeseed machinery is: crew preparation → cutting (hand harvesting) → placement → natural drying → picking → threshing → cleaning → rapeseed collection. The technical requirements are: the maturity of rapeseed reaches about 80% for manual harvesting, and the field is exposed for 5 days. When the maturity of rapeseed reaches more than 90%, the combine harvester is used for picking and threshing, and the stems should be broken. Evenly spread in the fields. Second, the best time for rape harvest: Harvesting rapeseed with a combine harvester, it is very important to grasp the harvest time of rapeseed. Premature harvesting, over ripening of rapeseed, and the rotation of the harvester's auger during the operation of the picking wheel will knock down the canola and cause waste. 1, in the upper part of the rape can be pinched with the fingers, the lower part of the fruit when the temperature is high when the touch is the best case. 2. Fields with inconsistent maturation have the best harvest performance when 50% of the fruit pods can fall when the temperature is high and the green pods do not exceed 35-5%. 3. The best harvest time for rape is early, late or cloudy days. 4. In the late stage of maturity, harvesting should be avoided when the temperature is high at noon. Third, the requirements of the combine harvester: 1. The technical performance of the harvester is required, and the connection and delivery sites are required to be closed tightly, and no leakage of particles occurs during the work. 2. When the locomotive is at harvest, the speed of the locomotive cannot be too fast, and only the medium and low speed can be selected. 3, pull out the rotation speed of the picking wheel to be adjusted to the lowest, in order to reduce the number of impacts on the rape; front and rear position to be transferred to the final, and according to the growth of the rape and the inverted state reasonable adjustment of its high and low position. If it is fitted with a toothed plate, it should be removed to reduce the impact on rapeseed. 4, according to the maturity of rapeseed and threshing effect of reasonable adjustment of the drum speed and gravure gap, better maturity or high temperature weather can reduce the speed and increase the gap, in the premise of ensuring the ratio of rapeseed to reduce the broken rate. 5, according to the locomotive work during the election and the loss of reasonable adjustment of the amount of wind, when the stem is wet, the amount of wind should be adjusted, dry, should be appropriately reduced. The wind direction should be adjusted to the front of the screening sieve. 6. The opening of the screening on the screen and the tail screen should be adjusted to be large enough to allow some of the unbleached barley to enter the debris elevator for further threshing. The opening of the lower sieve should be reduced or replaced with a fine mesh sieve. 7. The adjustment of locomotives should be based on the loss situation at the time of harvest. Fourth, the agronomic requirements: 1. Reasonably arrange the planting area of ​​rapeseed according to its own mechanical power, stagger the sowing date, so as to facilitate harvesting in stages. 2. In order to solve the problem of the lack of mechanical strength due to the concentration of crops, some rapeseeds can be cut down by hand in advance, laid horizontally or placed in a width shop, and picked up with a harvester after 2-3 days of drying. This method can be harvested 7-10 days in advance. 3. In order to facilitate machine harvesting, the width of the canola planter should be compatible with the width of the header, and the field head should have a transverse box with a width of two hatches as the turning area for the locomotive. 4, in the machine before the 7-10 days of receipt, should be divided into good compartment according to the ditch, so as to reduce the impact of the tiller on rapeseed damage. 5. Reasonable arrangements should be made for the planting time and variety of rape, and the management of water and fertilizer should be emphasized. The same field plots strive for the same degree of maturity, and a large number of mature seasons should be opened a certain distance. 6, in the late growth period of rapeseed, the method of chemical ripening rape can be used to mature the rape in order to reduce the waste caused by inconsistent green and yellow harvest. Fifth, combine harvester operating procedures: 1. Combine harvesters should be operated by professional personnel or professionally trained skilled operators, and they should be operated correctly according to the manual's safe operation procedures, and the harvester should be maintained and adjusted in time. 2. The crew must pay special attention to pedestrians and obstacles during operations, turning and shifting to prevent accidents. 3. Select a representative piece of land before the actual harvest to conduct a trial cut to check for problems not found in the test run. 4. Regularly check the operating condition of the locomotive and the quality of the work in the operation, and identify problems and adjust in time. The quality inspection includes cutting height, harvesting loss, cleanliness and breaking rate. 5, the operator must be proficient in the operation of the locomotive across obstacles, turning, harvesting, walking, unloading food. 6, walking method is generally used centripetal law. 7. When cutting the fallen crop, lower the header to an appropriate height, move the reel shaft forward, and correctly select the harvesting direction, preferably the reverse lodging direction, followed by the horizontal lodging direction. 8. Rapeseed harvesting is generally conducted on sunny days in the morning, in the morning and in the afternoon. Harvesting should be stopped before and after noon on sunny days. 9, after the operation is completed, first clean the locomotive, especially the drum, cleaning, transport part of the weeds, dust and other clean. 10. Remove all belts, apply anti-rust oil or paint, and keep in a dry and ventilated place. (Caution: rubber rollers should be used for padding).
