Abstract
The utility model discloses a seed sowing device for an oilseed rape precision seeder. The seed sowing device comprises a seed box, wherein the seed box is barrel-shaped, the seed box is internally provided with a planter plate and a seed scraper, an axle hole is formed in the center of the barrel bottom of the seed box, and a seed outlet is formed close to the barrel wall; the planter plate is tightly attached to the barrel bottom of the seed sowing device, a rotating shaft is fixedly arranged on the circle center of the planter plate, the rotating shaft is adapted to the axle hole and penetrates through the axle hole, a plurality of seed accommodating holes are formed in the same circumference, corresponding to the central position of the seed outlet, of the planter plate at intervals, and one to three oilseed rape seeds can be accommodated in each seed accommodating hole; the seed scraper is fixed above the seed outlet, the seed scraper is internally provided with an elastic rod and a seed knocking ball, and the seed knocking ball is elastically positioned above the seed outlet. During the sowing process, the planter plate rotates, and when a certain seed accommodating hole rotates to be overlapped with the seed outlet, the oilseed rape seeds inside the seed accommodating hole are knocked out by the seed knocking ball, so that the oilseed rape seeds pass through the seed outlet to enter an externally connected seed guide tube so as to fall in holes. The seed sowing device is simple in structure and reliable to sow, and can realize single grain hand sowing and precision sowing of two to three grain hole sowing.
Description
Technical field
The utility model belongs to agricultural mechanical field, and what relate to is a kind of seeding parts on rape seeding machine, and what be specifically related to is a kind of rape precision seeder seeding unit.
Background technology
Along with the fast development of Tendency of Agricultural Machinery in China, the development of domestic various novel rape seeding machineries emerges in an endless stream.Current rape seeding machine be take drill planter and air-suction seeding unit as main.Because rapeseed seeds grain is very little, drill planter continuously every sowing characteristic, will inevitably cause the serious waste of seed, and the thinning amount after emerging is very large, cost is very high; The complex structure of air-suction seeding unit, requirement on machining accuracy is high, and power consumption is large, sometimes because operating air pressure is unstable, there will be the phenomenon of discharging without planting, and causes and is short of seedling, and finally affects output.So, develop that a kind of seeding is reliable and can to realize the rape precision drilling seeding unit of simple grain program request or the bunch planting of 2-3 grain necessary.
Summary of the invention
The purpose of this utility model is to overcome the existing above-mentioned deficiency of seeding unit on existing rape seeding machine, proposes a kind of simple in structure, the reliable rape precision seeder of seeding seeding unit.
The technical scheme that realizes above-mentioned purpose is: a kind of rape precision seeder seeding unit, comprise seed-box, and in described seed-box, be provided with seed plate and seed scraping device, seed-box is drum-shaped, there is an axis hole at Tong Di center, near bucket wall position, has one to go out kind of a mouth, goes out kind of a mouth and is circumscribed with grain conductor; Described seed plate is close to the bucket end of seeding unit, its diameter is suitable with bucket end diameter, on the center of circle of seed plate, be installed with a rotating shaft, this rotating shaft and described axis hole are adaptive and through axis hole, on seed plate with described in go out on same circumference corresponding to kind of mouth center, to be interval with a plurality of kind of holes of receiving, each is received in kind of hole only can hold 1-3 grain rape seed; Described seed scraping device is fixed on out the top of kind of mouth, and the lower edge of seed scraping device forms matched in clearance with the upper surface of seed plate, is provided with an elastic rod in seed scraping device, and elastic rod termination is equipped with one and is hit kind of a ball, hits kind of ball elasticity and is positioned at kind of a mouth top.
In seeding process, described rotating shaft drives by sower, seed plate rotation, under the effect of seed scraping device, except dropping on the seed of receiving in kind of hole, all the other seeds are all blocked in the outside of seed scraping device, when certain, receiving kind of a hole goes to when going out kind of salty closing, Ji Zhong club hits the rape seed of receiving in kind of hole, makes it by going out kind of a mouth, enter grain conductor, and then falls into cave nest.
The utility model simple structure, seeding is reliable, can realize the precision drilling of simple grain program request or the bunch planting of 2-3 grain.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the floor map of seed plate.
In figure: 1. seed-box, 101. axis holes, 102. seed outlets, 2. seed plate, 201. receive kind of a hole, 3. rotating shaft, 4. seed scraping device, 5. elastic rod, 6. hits kind of a ball, 7. grain conductor.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, it comprises seed-box 1 the utility model, is provided with seed plate 2 and seed scraping device 4 in seed-box 1, seed-box 1 is drum-shaped, there is an axis hole 101 at Qi Tongdi center, near bucket wall position, has one to go out kind of mouth 102, goes out kind of mouth 102 and is circumscribed with grain conductor 7; At the bottom of seed plate 2 is arranged in seed-box 1 and is close to barrel, there is a reasonable clearance that can guarantee seed plate 2 rotations between the two, the diameter of seed plate 2 is suitable with the diameter at the bucket end, on its center of circle, be installed with a rotating shaft 3, rotating shaft 3 is with axis hole 101 adaptations and through this axis hole, on seed plate 2, on the same circumference corresponding with going out kind of mouth 102 centers, be interval with a plurality of kind of holes 201 of receiving, each is received in kind of hole 201 only can hold 1-3 grain rape seed; Seed scraping device 4 is a small box, be fixed on out in the seed-box 1 of kind of mouth 102 tops, the lower edge of seed scraping device 4 forms matched in clearance with the upper surface of seed plate 2, guarantee that seed plate 2 levels rotate freely, in seed scraping device 4, be provided with an elastic rod 5, elastic rod 5 terminations are equipped with one and are hit kind of ball 6, hit the top that kind of ball 6 elasticity are positioned at kind of mouth 102.
Conventionally, the diameter of seed plate 2 is comparatively suitable with 150-200mm, and kind of hole 201 quantity of receiving on it are determined according to the speed of travel of rotating shaft 3 rotating speeds and sower, generally get 12-18, receives the slightly larger in diameter in kind of hole 201 in the diameter of rape seed.Point sowing time, receive in kind of hole 201 and only allow to hold 1 seed; During bunch planting, receive that kind of hole 201 is interior allows at most to hold 3 seeds.
