摘要：【中文】本发明涉及一种回转窑离合装置，包括：斜齿离合器第一部，与主减速机输入轴连接；斜齿离合器第二部，与辅减速机输出轴连接，并与斜齿离合器第一部呈相对设置，斜齿离合器第二部可朝向、背离斜齿离合器第一部的方向移动；连接部，与斜齿离合器第二部固定连接，用于带动斜齿离合器第二部朝向、背离斜齿离合器第一部的方向移动，且设定连接部在第一位置时，带动斜齿离合器第二部与斜齿离合器第一部啮合，连接部在第二位置时，带动斜齿离合器第二部与斜齿离合器第一部分离；驱动系统，与连接部连接。本发明可实现在故障断电停窑后第一时间内将辅减速机输出轴与主减速机输入轴自动合闸的功能，无需人工操作，第一时间即可使回转窑恢复转动。 【EN】The invention relates to a rotary kiln clutch device, comprising: the first part of the helical gear clutch is connected with the input shaft of the main speed reducer; the second part of the helical tooth clutch is connected with the output shaft of the auxiliary speed reducer and is arranged opposite to the first part of the helical tooth clutch, and the second part of the helical tooth clutch can move towards and away from the first part of the helical tooth clutch; the connecting part is fixedly connected with the second part of the helical gear clutch and used for driving the second part of the helical gear clutch to move towards and away from the first part of the helical gear clutch, and when the connecting part is set to be at a first position, the second part of the helical gear clutch is driven to be meshed with the first part of the helical gear clutch, and when the connecting part is set to be at a second position, the second part of the helical gear clutch is driven to be separated from the first part of the helical gear clutch; and the driving system is connected with the connecting part. The invention can realize the function of automatically switching on the output shaft of the auxiliary speed reducer and the input shaft of the main speed reducer in the first time after the kiln is stopped due to power failure, and the rotary kiln can be recovered to rotate in the first time without manual operation.

摘要：【中文】本发明公开了一种水稻专用增效免追控释肥及其制备方法，其中，所述控释肥包括：20～28重量份的N、8～15重量份的P₂O₅、10～14重量份的K₂O、0.1～0.3重量份的Zn、0.1～0.3重量份的Si，其中，所述N包括速效氮、中效氮和长效氮，所述速效氮提供0～60天的氮素养分，所述中效氮提供60～90天的氮素养分，所述长效氮提供90～120天的氮素养分。该控释肥配方比例合理，养分全面，一次施肥后期不用追肥，并且养分满足水稻整个生育期的需求且吻合水稻“S”型养分需求规律，从而在提高肥料利用率的同时显著提高水稻产量。 【EN】The invention discloses a synergistic topdressing-free controlled release fertilizer special for rice and a preparation method thereof, wherein the controlled release fertilizer comprises the following components: 20-28 parts of N and 8-15 parts of P₂O₅10 to 14 parts by weight of K₂The nitrogen-containing composite material comprises O, 0.1-0.3 part by weight of Zn and 0.1-0.3 part by weight of Si, wherein the N comprises quick-acting nitrogen, intermediate nitrogen and long-acting nitrogen, the quick-acting nitrogen provides nitrogen nutrients for 0-60 days, the intermediate nitrogen provides nitrogen nutrients for 60-90 days, and the long-acting nitrogen provides nitrogen nutrients for 90-120 days. The controlled release fertilizer has reasonable formula proportion and comprehensive nutrients, does not need additional fertilizer at the later stage of one-time fertilization, and the nutrients meet the requirement of the rice in the whole growth period and are consistent with the requirement rule of the S-shaped nutrients of the riceAnd the yield of rice is obviously improved while the utilization rate of the fertilizer is improved.
