Description

Agricultural fertilizer sustained-release device Technical Field The utility model relates to the technical field of fertilizer slow-release devices, in particular to an agricultural fertilizer slow-release device. Background An agricultural fertilizer slow release device generally refers to a technology for controlling the release rate of a fertilizer, and aims to improve the utilization rate of the fertilizer, reduce environmental pollution and reduce the fertilization frequency of farmers. Currently, fertilizer slow release devices generally take the form of a barrel-like structure with one or more slow release openings on the surface for the outflow of liquids (including but not limited to fertilizer and water) therein. However, the outflow speed of the liquid in the slow-release mouth is too slow, so that the sedimentation phenomenon of fertilizer particles in the liquid in the slow-release mouth is easy to occur, the content of fertilizer in the liquid flowing out along the slow-release mouth is low, even no fertilizer exists, and further crops cannot obtain enough nutrients, and normal growth and development of the crops are affected. Disclosure of utility model The utility model mainly aims to provide an agricultural fertilizer slow-release device, which aims to solve the problem that the internal fertilizer is deposited due to the fact that liquid in a slow-release barrel is in a static state, so that the fertilizer application effect of the device is affected. In order to achieve the above purpose, the technical scheme of the utility model is as follows: The agricultural fertilizer slow release device comprises a slow release barrel, wherein a slow release opening is formed in the slow release barrel, a stirring structure is arranged on the slow release barrel, the stirring structure comprises stirring paddles and a stirring motor used for controlling the stirring paddles to rotate, an anti-blocking structure used for preventing the slow release opening from being blocked is arranged in the slow release opening, and the anti-blocking structure and the stirring structure are in linkage. Further, the stirring paddle is provided with a linkage cam, the anti-blocking structure comprises an anti-blocking rod, a reset elastic piece and a sliding frame, the sliding frame is fixedly arranged in the slow-release barrel, the reset elastic piece is positioned between the anti-blocking rod and the sliding frame, and the anti-blocking rod is in linkage with the linkage cam, is in sliding connection with the anti-blocking rod and can be embedded into the slow-release opening. Further, the cross section of the anti-blocking rod is of an H-shaped structure, and the reset elastic piece is located at one end of the sliding frame far away from the slow release port. Furthermore, the slow release openings and the anti-blocking structures are all provided with a plurality of anti-blocking structures, and the anti-blocking structures and the slow release openings are uniformly distributed around the circumference of the slow release barrel and are matched with each other in a one-to-one correspondence manner. Further, the anti-blocking rod comprises a cleaning plate, the cleaning plate is located at one end of the sliding frame close to the slow-release opening, and the distance between the sliding frame and the slow-release opening is larger than the length of the cleaning plate in the radial direction of the anti-blocking rod. Further, the linkage cam is provided with a plurality of protruding parts. Further, a supplementing pipe is arranged on the slow release barrel and communicated with the inside and the outside of the slow release barrel. The working principle and the beneficial effects of the utility model are as follows: The technical scheme of the utility model adopts a stirring structure which can be matched with the slow release barrel to stir the liquid in the slow release barrel, so that the liquid in the slow release barrel is in a flowing state, thereby effectively preventing fertilizer from depositing in the liquid, and ensures that the fertilizer can be uniformly mixed with the liquid in the barrel by virtue of the stirring effect of the stirring structure, thereby effectively ensuring the fertilizer content in the liquid flowing out along a slow release opening on the slow release barrel, and further ensuring the fertilizer applying and fertilizer supplying effects of the utility model. Meanwhile, an anti-blocking structure is further arranged in the slow release opening on the slow release barrel, and plays a role in dredging the slow release opening, so that soil and soil particles are prevented from blocking the slow release opening when the slow release barrel is buried in soil, and the liquid outlet efficiency of the slow release barrel is influenced.
