Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grass seed spraying for agricultural pasture, in particular to a grass seed granule spraying machine for agricultural pasture. BACKGROUND

[0002] Grass seed spraying is a key link in the cultivation of vegetation and the repair of degraded grassland in agricultural pasture, and its operation efficiency, spraying uniformity and equipment adaptability directly affect the grassland vegetation coverage and growth quality.

[0003] At present, existing grass seed spraying equipment mainly includes large mechanical spraying equipment and small manual spraying equipment, but both have significant defects in practical application: first, the driving mode is unreasonable. Most existing equipment adopts the design of independent driving of the grass seed transmission mechanism and the spraying fan, and the transmission rate and the spraying air volume need to be adjusted respectively through multiple control switches, which leads to poor synchronization of the two, and problems such as "transmission quantity greater than spraying quantity causing pipeline congestion" or "transmission quantity less than spraying quantity causing empty spraying waste" are prone to occur. Some small equipment even has no gear adjustment function and can only operate at a fixed rate, which cannot adapt to the diversified needs of large-scale spraying in open pasture and precise spraying in corner areas. Second, the grass seed transmission and spraying structure design is imperfect. Most existing equipment directly transports grass seeds through a single pipeline, lacks effective dispersion and diversion mechanism, and grass seeds are prone to stick together in humid environments, causing frequent pipeline blockage. At the same time, during the spraying process, the distribution of grass seeds in the airflow is chaotic, with accumulation in the center and sparseness at the edges, and the grass seeds at both ends of the pipeline are difficult to be effectively guided to the spraying port, resulting in poor spraying uniformity and uneven growth of grassland vegetation. Third, the spraying aperture adjustment performance is insufficient. Most equipment adopts a fixed spraying aperture design, and if the spraying range needs to be adjusted, the equipment needs to be moved manually or the nozzle needs to be replaced, which is cumbersome and inefficient. A few devices with adjustable apertures use a manual screw adjustment ring, which has low adjustment accuracy and is prone to aperture deviation during operation due to equipment vibration, affecting the spraying effect. Fourth, the equipment structure design lacks rationality. Most existing large spraying equipment is of an integral welded structure, and when the core components are damaged, the equipment needs to be disassembled and repaired as a whole, which is high in maintenance cost and low in efficiency. At the same time, the equipment is large in size and has a large turning radius, making it difficult to move flexibly in narrow passages or hilly terrains in the pasture, limiting its adaptability. Small manual equipment has the problems of low operation efficiency and high labor intensity, which cannot meet the operation needs of large-scale pasture.

[0004] In summary, existing grass seed spraying equipment has obvious deficiencies in driving synchronization, anti-clogging performance, spraying uniformity, aperture adaptability and maintenance convenience, and cannot meet the diversified, efficient and precise grass seed spraying needs of agricultural pasture.

[0005] Therefore, we propose a grass seed granule spraying machine for agricultural pasture. SUMMARY
