The utility model relates to the field of agricultural machinery, in particular to a ridging and shaping device for ridge leveling operation, which comprises a rack, a knife roll, a ridge scraper and a leveler are sequentially arranged on the rack in the direction opposite to the advancing direction, the leveler is positioned on the central surface of the rack along the advancing direction, and the leveler is arranged on the rack in a liftable manner through an elastic pre-tightening component. The two groups of ridge scrapers are symmetrically arranged about the central plane and are positioned on one side, far away from the central plane, of the leveler, and the knife roll is positioned on one side, far away from the central plane, of the ridge scrapers. According to the ridging and shaping device for ridge leveling operation, the knife roll, the ridge scraper and the automatic profiling leveler are adopted for combined row rotary tillage ridge leveling operation, the structure is simple and convenient, the operation performance such as the height, the width and the flatness of a ridge after operation is excellent, the sowing effect and performance of a ridging and sowing machine can be improved, and therefore the planting yield and benefits are improved; meanwhile, the adaptability to different working conditions is good, and the market application prospect is good.

The utility model discloses a kind of seeding mechanism and agricultural integrated planting equipment, the seeding mechanism includes mounting seat;Seed material bin is installed in mounting seat, and is formed with seed material cavity and the blanking opening being communicated seed material cavity, feeding roller is set in seed material cavity, and is rotatably connected with seed material bin;Limiting material piece is set in seed material bin, and with feeding roller interfitting forms blanking gap, limiting material piece can move towards or is away from the side of feeding roller, to make blanking gap reduce or expand.In the application, limiting material piece and feeding roller interfitting forms blanking gap, the size of this blanking gap can be adjusted according to the speed of sowing, that is, the number of seed falling into blanking opening in unit time can be adjusted by the size of blanking gap, so the speed of sowing and the number of sowing in unit time can be adjusted, on the one hand, not only can avoid the condition that seed is too much in single planting area and exceeds planting specification;On the other hand, the waste of seed can be greatly reduced.

The utility model relates to the field of agricultural machinery, in particular to a leveling device for ridging and seeding, which comprises a rack, the adjusting shaft is movably connected with the rack, and an elastic pre-tightening assembly is arranged on the adjusting shaft; one end of the shaping plate is rotationally connected with the rack, the other end of the shaping plate is rotationally connected with the elastic pre-tightening assembly, the shaping plate is provided with an inclined shaping face facing the advancing direction of the rack, and the included angle between the inclined shaping face and the horizontal plane ranges from 5 degrees to 30 degrees. The leveling device for ridging and sowing can be adjusted in a self-adaptive profiling mode according to ridge height changes, the structure is adjustable, performance is stable, the application range is wide, and production cost is saved.

The utility model discloses a seed-metering device with intercropping, seeding and fertilizing integrated function, which comprises a frame, a plurality of seed groove shells, a rotatable clamping type seed-metering unit, an adjusting mechanism, a blanking mechanism and a feeding mechanism, the plurality of seed groove shells are fixedly connected on the frame, the top ends of the plurality of seed groove shells are provided with feed ports, and the feed ports are connected with the rotatable clamping type seed-metering unit. A plurality of seed groove shells are arranged on the rack, discharge ports are formed in the bottom ends of the seed groove shells, rotatable clamping type seed metering units are arranged in the seed groove shells, adjusting mechanisms are arranged on the seed groove shells, the adjusting mechanisms correspond to the rotatable clamping type seed metering units in a one-to-one mode, and the discharging mechanism is arranged in the rack. According to the seed metering device with the intercropping, sowing and fertilizing integrated function, seeds can be uniformly arranged and then sown, the phenomenon of miss-sowing or repeated sowing is not likely to be caused, the seeds are fixed and released through opening and closing of the seed clamp in the sliding groove, the seed metering device can adapt to different kinds of seeds, and the sowing efficiency and effect are improved.
