A fertilizing device for agricultural planting comprises a fertilizer containing groove, a driving shaft, a driven chain wheel, a transition feeding hose, a swing screening block, a fertilizing block driving motor and a dispersing fertilizing block, a screening mechanism bearing groove is formed in the bottom of the fertilizer containing groove, a lower containing groove is formed in the bottom of the screening mechanism bearing groove, and the screening mechanism bearing groove is matched with the swing screening block; the material screening mechanism bearing groove is connected with a swing screening block, the swing screening block rotates in the material screening mechanism bearing groove, a swing mechanism bearing groove is formed in the side face of the material screening mechanism bearing groove, screening shifting blocks and a side guiding flat groove are arranged at the top of the swing screening block, the three screening shifting blocks are evenly arranged at the top of the swing screening block, and screening holes are formed in the upper surface of the swing screening block. Each group of screening holes is located in the two sides of the screening shifting block, and the side guide flat grooves are located in the two sides of the screening shifting block array group.

This invention relates to a protein enzyme compound organic fertilizer and its preparation method, belonging to the field of organic fertilizer processing technology. The protein enzyme compound organic fertilizer uses a core sphere as the matrix, and an inner shell layer and an outer shell layer are sequentially coated on the outside of the core sphere. The inner shell layer and the outer shell layer are formed by the continuous adhesion and accumulation of the inner shell layer coating material and the outer shell layer coating material through a rolling coating method, thickening layer by layer to form the inner shell layer and the outer shell layer, respectively. Using a core sphere loaded with organic microbial agent as the matrix, a double-layer coating structure of inner shell layer and outer shell layer is sequentially coated. The core has a porous steam-exploded straw carrier with well-developed pores, which can adsorb and fix beneficial microorganisms such as Bacillus subtilis and Bacillus spp.; the inner shell layer contains hydroxyethyl cellulose, which slowly swells upon contact with water to form a water-resistant buffer layer, initially isolating external moisture impact; the outer shell layer adopts a chitosan system, where chitosan fully dissolves under weakly acidic conditions to form a film, constructing an outer slow-release barrier.

This invention discloses a vibrating grassland organic fertilizer granule screening and application device, belonging to the field of organic fertilizer application technology. It includes a hopper fixedly connected to a fertilizer applicator, and further includes: a screening cylinder fixedly connected to the fertilizer applicator, with a detachable cover at the top; a drive rod rotatably connected to the cover, with a first stirring blade fixedly connected to its bottom; and a drive block slidably connected to the drive rod, with a connecting rod fixedly connected to its side wall, a hanging rod fixedly connected to the connecting rod, and a second stirring blade fixedly connected to its bottom end. This invention uses a first drive motor to drive the drive rod to rotate. The first stirring blade on the drive rod, and the second stirring blade that slides and rotates with the drive block work together to fully stir and beat the fertilizer in the screening cylinder, effectively breaking up compacted fertilizer clumps and preventing localized soil "burning" caused by concentrated fertilizer clumps during application, thus ensuring the normal growth of subsequent crops.

The invention discloses a fertilizing device for corn cultivation, and relates to the technical field of intelligent agricultural machines.The fertilizing device comprises a rack and a ditching wheel, the ditching wheel is arranged below the rack, a fertilizing barrel is erected on the rack, and a feeding cavity is formed in the fertilizing barrel. The driving part drives the multiple feeding shafts to rotate at different transmission ratios, the feeding grooves formed in the feeding shafts and the telescopic flexible pads in the feeding grooves are combined, different nitrogen, phosphorus and potassium fertilizers in the feeding cavity can be put in different proportions, the dynamic requirements of corn for elements such as nitrogen, phosphorus and potassium in different growth stages are met, and the corn planting efficiency is improved. The phenomena of seedling burning or insufficient fertilizer supply and the like caused by unbalanced proportioning are avoided, the feeding amount of each chemical fertilizer can be accurately controlled, and the problem of low chemical fertilizer proportioning precision of a traditional fertilizing device is effectively solved.
