Abstract
The invention relates to a bucket wheel type hill-drop planter capable of adjusting planting distance. The bucket wheel type hill-drop planter is composed of three main parts, i.e., a built-in seeding unit capable of adjusting planting distance, a hill-drop planter device for secondary seed placement, and a seed placement phase angle regulating part. The bucket wheel type hill-drop planter rolls on a mulching film for seeding; a shaft drives seed scoops arranged on a seed distributor base in an array mode to rotate; the seed scoops scoop up a plurality of seeds from a seed heap in a transparent cover, redundant seeds drop off by virtue of dead weight along with the upward rotation of the seed scoops, one seed remained in each seed scoop is taken to a seed distributor component through an opening of a partition plate, and the seed distributor component and the seed scoop rotate synchronously; when the seed in the seed distributor component is transferred to a primary seed placement interface located at the lowest position, the seed drops into a secondary seed receiving guide groove, and then drops into a duckbill of the hill-drop planter device for secondary seed placement after 270-degree rotation for temporary storage; and when the duckbill enters into soil after rotation, the seed can be precisely and stably placed onto a seed bed, so that precise hill-dropping process is finished.
Description
Technical field
Originally the present invention relates to the adjustable dibbler of a kind of scoop-wheel spacing in the rows, belong to the technical field of agricultural machinery aspect.
Background technology
Known technology, as China Patent No.: 201020102161.9 " planting a spoon formula mechanical precision dibbler " is installed with Moving plate by bearing on dibbler axle, on the periphery of Moving plate, be fixedly mounted with sowing circle and platen, on the uniform planting mouth of sowing circle, sowing duckbilled is installed respectively, on dibbler axle, be fixedly mounted with the price fixing matching with Moving plate, the uniform seed guiding groove that outer end opening is being set in the card of getting Moving plate outside kind of spoon dish, get uniform installation on kind of spoon dish to get kind of spoon corresponding with seed guiding groove, what in price fixing coil end, be fixedly mounted with is getting between kind of spoon and seed guiding groove every kind of dish, by get kind of spoon dish and price fixing every kind of dish and Moving plate, form and deposit kind of a chamber, on the top every kind of dish, seeding breach is being set.During sowing, seed is transported to dibbler seed inlet by kind of pipe the seed of planting case, enters into deposit kind indoorly, guarantees to deposit kind indoor a certain amount of seed that has.This seeder rolls on the ground, drives Moving plate, gets kind of spoon and seed guiding groove and rotates.When getting kind of spoon when depositing the seed zone of middle chamber, by getting kind of spoon, by the endless belt Xing Zhong district forming every kind of dish bottom and price fixing, seed is picked up.When getting kind of spoon and forward the seeding breach every kind of dish top to, get kind of spoon not every the obstruct of kind of dish, at this moment seed drops in seed guiding groove by deadweight.When this seed guiding groove goes to below, under the guiding of seed guiding groove, seed enters into dibbler sowing duckbilled, and dibbler is rotated further, and sowing duckbilled enters movable nozzle in soil and opens, and seed falls in hole, soil cave and completes seeding operation.
As China Patent No.: " can change a kind of Combined type seed dish of spacing in the rows " of 201020102162.3, comprise Moving plate, affixed kind of the spoon dish of getting on Moving plate, get kind of a spoon locating slot getting uniform setting in kind of the card of spoon dish, the Combined type seed dish that seed guiding groove piece by uniform arrangement constitutes is being set on the periphery of getting Moving plate card outside kind of spoon dish, on seed guiding groove piece, seed guiding groove is being set, on the bottom surface of seed guiding groove, screw hole is being set, on Moving plate card disc, the screw hole of uniform setting is corresponding one by one with the screw hole on each seed guiding groove piece seed guiding groove bottom surface on Combined type seed dish, uniform seed guiding groove piece is fixed in respectively in Moving plate card by screw.The present invention is affixed Combined type seed dish on Moving plate, and Combined type seed dish is fixed in respectively in Moving plate card by screw by the seed guiding groove piece of uniform arrangement, on every seed guiding groove piece, seed guiding groove is being set respectively.
As China Patent No.: 201020102158.7 a kind of replaceable seed taking disc of getting kind of spoon, the Moving plate that comprises mechanical precision hill-drop drill, on Moving plate, arranging and getting kind of a spoon dish, get in kind of the card of spoon dish uniform arranging opening outwardly get kind of a spoon locating slot, in uniform getting on kind of spoon locating slot, by screw, removable kind of the spoon of getting is installed respectively, in the card of getting Moving plate outside kind of spoon dish, the uniform opening seed guiding groove outwardly that arranging, gets kind of spoon locating slot corresponding one by one with seed guiding groove.Due to Moving plate get the getting on kind of spoon locating slot of uniform setting on kind of spoon dish, removable kind of the spoon of getting is installed respectively, get kind of spoon and match with the seed guiding groove of uniform setting in Moving plate card.In sowing work, rotate Moving plate drive and get kind of a spoon rotation, forwarding kind of the bale-out of getting of getting kind of position to obtains seed follower disk rotation and goes upward to planting mouth and fall in corresponding seed guiding groove, the seed guiding groove that carries seed when Moving plate goes to the below of seeder, seed relies on deadweight to fall into sowing duckbilled along seed guiding groove, is sown in soil pit.
Above patent all adopts axle stationary device, both there is no the accurate secondary mechanism of charging seed, and does not also have seeds fall to arrive the phase angle guiding mechanism of bunch planting duckbilled.
Summary of the invention
The problem that this present invention solves is to overcome the deficiency that original dibbler exists, and provides a kind of scoop-wheel spacing in the rows adjustable dibbler.
The dibbler that scoop-wheel spacing in the rows is adjustable, comprises by the built-in seeding unit of regulatable fertilizer applicator, the dibbler device (25) that secondary is charged seed, the adjustment member at the phase angle of charging seed, and three major parts form.At mulch film upper seeding wheel, roll, by axle (5), drive kind spoon (2) rotation at the upper array of seeder seat (6), in seed heap in translucent cover (1), plant spoon (2) and ladle out several seeds, the rotation making progress along with kind of a spoon (2), unnecessary seed glides by deadweight, a seed in remaining kind of spoon (2) is by the opening part of dividing plate (15), be brought in seeder assembly (9), seeder assembly (9) and kind spoon (2) synchronous rotary, when the seed in seeder assembly (9) is sent to the interface of once charging seed (19) of below, fall within secondary inoculation guide groove (20), turn over again in the duckbilled (22) that 270 ° of angles fall within the dibbler device B (25) that secondary charges seed later and store temporarily, when continuing to forward to duckbilled (22) and burying, seed is precise and stable being placed on kind of bed thereupon, reached precise hole sowing process.
The built-in seeding unit of described regulatable fertilizer applicator adjustable: be when plant strain is apart from need to change time, if: plant strain is when changing to every meter of six strain by every meter of four strains.The dibbler device B (25) that kind spoon (2), a seeder assembly (9), secondary are charged seed also needs to change restructuring.
