When the motor 221 is started, the driven shaft 224 rotates, the gear 223 drives the gear ring 222 meshed with the driven shaft to rotate, and the gear ring 222 is fixedly connected with the connecting cylinder 212 at the top end of the cylindrical hole type spray head 21, so that the connecting cylinder 212 drives the cylindrical hole type spray head 21 to rotate relative to the tower top 12.
As shown in fig. 4, the top end of the tower 11 is provided with a foreign matter storage chamber 14 detachably connected to the foreign matter collection chamber 3222, and a foreign matter discharge port which can communicate with the foreign matter storage chamber 14 is provided at a lower portion of an inner cavity of the foreign matter collection chamber 3222.
In order to facilitate cleaning of foreign matters in the foreign matter collection bin 3222, a foreign matter storage bin 14 which can be connected with the foreign matter collection bin 3222 is installed on the tower top 12, so that the foreign matters in the inner cavity of the foreign matter collection bin 3222 can fall into the foreign matter storage bin 14, and when cleaning is required, the foreign matter storage bin 14 is detached from the foreign matter collection bin 3222, so that the foreign matters in the foreign matter collection bin 3222 are cleaned.
The granulation mechanism of tower granulation is applied to the preparation of the high-tower fulvic acid compound fertilizer, the application of the preparation of the fulvic acid compound fertilizer is realized by adopting the granulation mechanism of tower granulation, and foreign matters blocked in the holes of the cylindrical hole type spray head 21 are sucked inwards by the cleaning mechanism.
Through the cylindrical eyelet type spray head 21 capable of preventing blockage, the preparation efficiency of the fulvic acid compound fertilizer can be effectively improved, and the need of shutdown cleaning or spray head replacement is avoided.
The foregoing examples merely illustrate one or more embodiments of the invention, which are described in greater detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of the invention should be assessed as that of the appended claims.
