Rice throwing cultivation techniques have the advantages of high production efficiency, guaranteed agricultural time, increased production, and so on. They have been widely used in recent years. The essence of the method is the use of a rake-type floppy seedling for raising seedlings. The seedlings are thrown into the field by throwing seedlings or artificially. 2ZPY-C type rice throwing machine is one of the main models currently used. Now the machine is taken as an example to introduce the use of the rice throwing machine as follows: Installation: Remove the first bolt on both sides of the center of the chassis. Align the mounting holes of the rack, tighten with bolts, and connect the universal coupling to the input shaft of the gearbox. Inspection and maintenance: Before work, check whether the connection of each component is firm, whether the fastening bolts are loose and whether the moving parts are flexible. After the end of each shift, it is necessary to clean the casting machine. In particular, the anti-rust oil should be wiped off to ensure that it can work normally. During the operation, the condition of the surface of the disc is often observed, and it is found that the phenomenon of clay should be stopped in a timely manner. Each time the basket is mounted, the disc is cleaned once to prevent the clay from being thrown away. Adjustment: According to the rice seedling machine forward speed and agronomic requirements, change the throwing density by adjusting the amount of seedling feeding, and adjust the range to 20-45 holes per square meter. Changing the relative position of the feeding hopper and the shroud can change the throwing direction of the seedlings and the position of the sprinkler belt. Site preparation requirements: Fine soil preparation, so that "individual water is not exposed to mud," usually after hanging machine hanging a wooden pole, so that the field surface formation, to "watermelon" water status, which will help cast. Weather requirements: In case of windy weather, the traveling route of the threshing machine is determined according to the direction of the wind and is always parallel to the wind direction. When the wind exceeds 4, the operation should be stopped so as not to affect the quality of casting.
