Abstract
The utility model discloses an accurate sowing deed discharging machine of horizontal circular disk type that is comprised of a seed box, a seed discharging plate that is arranged on the seed box bottom and has a seed holding hole, as well as a seed scraping device and a seed pushing device arranged at a seed outlet on the seed box; wherein, the seed discharging plate is rotatablely connected with the seed box through a rotating shaft. The utility model is characterized in that: a circular socket that is coaxial with the rotating shaft is arranged on the seed discharging plate; and the seed holding hole is evenly arranged on the bottom of the circular socket along the circumference. As the seed discharging plate is provided with a circular socket, and the seed holding hole is arranged on the bottom of the socket, the seeds inside the seed box are easy to be filled inside the socket compactly due to the guide of the side on the socket, thereby effectively improving the seed charging efficiency. The accurate sowing seed discharging device of horizontal circular disc type is unlikely to damage the seeds, and has a good sowing performance, and can meet the requirements on accurate bunch planting of various corps in glebes and paddy fields.
Description
Technical field
The utility model relates to a kind of seeding unit of sower, and especially the architecture advances of horizontal circle disc type precise sowing seeding unit belongs to agricultural machinery technological field.
Background technology
Horizontal circle disc type precise sowing seeding unit is made up of parts such as seed-box, seed plate, seed scraping device and ejector blades, mainly is used in precision and broadcasts on the sower of dry crop seeds such as corn, jowar, soybean.The seed plate that is shaped on Rong Zhongkong is installed in the bottom of seed-box, is rotationally connected by rotating shaft and seed-box.During work, seed in the seed-box is filled into by deadweight in the appearance kind hole of the seed plate that is rotating along with the seed plate rotation, when rotating to the seed scraping device position, wiped off unnecessary seed by seed scraping device, when being retained in the seed that holds in kind of the hole and forwarding the outlet of seeder to, seed falls in the kind ditch of being left by seed-furrow opener in deadweight and ejector blade effect.This seeding unit can be realized equidistant cavitation, quantitatively sowing, and the seeding accuracy height can be saved a large amount of seeds and thinning labour.
But, below existing, the horizontal circle disc type precise sowing seeding unit of prior art has influence on the fault of construction of sowing performance:
1, seed plate is the plane disc structure, holding kind of a hole is arranged on equably near on the outer peripheral circumference of plane disc, fill kind of a poor-performing, particularly be used on the paddy planter, because rice paddy seed rough surface, the seed humidity of soaking before broadcasting are bigger, the mobile performance of seed is bad, and it is poorer to fill kind of performance, thereby can cause serious broadcast leakage;
What 2, seeding unit adopted is bar shaped brush hairbrush, the long limit of hairbrush brush and the radial parallel of seed plate, thereby meet kind of area and increased the seed plate rotary resistance greatly, and can make a part of seed be deposited in hairbrush all the time and meet a side of planting, not only influence is clear plants quality, and can cause the seed damage;
3, plant the star-wheel that device is rotation clearly, structure is complicated, and hinders easily and plant.
Summary of the invention
The technical problems to be solved in the utility model is: the shortcoming at above prior art exists, can satisfy various dry lands, paddy field crop hole sowing sowing requirement, the good horizontal circle disc type precise sowing seeding unit of sowing performance by the architecture advances proposition is a kind of.
In order to solve above technical problem, the horizontal circle disc type precise sowing seeding unit that the utility model proposes, comprise seed-box, be installed in seed-box bottom, be shaped on Rong Zhongkong seed plate, be arranged on the seed scraping device and the ejector blade at seed-box seed outlet place, seed plate is rotationally connected by rotating shaft and seed-box, its architecture advances is, be shaped on the toroidal cavity concentric on the seed plate, hold kind of a hole and be arranged on equably on the bottom surface of toroidal cavity along circumference with rotating shaft.
The inside and outside side of the toroidal cavity of above-mentioned seed plate is respectively positive round table surface and rounding table top with respect to rotating shaft.
Another improvement of the present utility model is, seed scraping device is the bar shaped hairbrush, and this hairbrush is positioned at the top of seed-box seed outlet, and the length direction of brush is tangentially parallel with seed plate.
Further architecture advances of the present utility model is, ejector blade is that the bottom is made toroidal and can be entered the elasticity of holding in kind of the hole and pushes away kind of a bar, and this elasticity pushes away the brush that kind of bar is arranged in described hairbrush, and its upper end is connected with the brush holder of hairbrush.
Compared with prior art, horizontal circle disc type precise sowing seeding unit of the present utility model, because its seed plate is shaped on annular groove, holding kind of a hole is arranged on the bottom surface of groove, be subjected to the guiding of groove side, the seed of seed-box is easy to be filled in the groove densely, thereby has improved seed-filling rate effectively; Because the length direction of hairbrush brush is tangentially parallel with seed plate, it is little to meet kind of area, and the interior seed of seed-box can evenly flow, so it is little, effective to plant resistance clearly; Adopt elasticity to push away kind of a bar and push away kind, simplified the structure of ejector blade, injuring-free seed.
Test shows that the utility model horizontal circle disc type precise sowing seeding unit does not damage seed, and the sowing performance is good, can satisfy various dry lands, paddy field crops precision hill-drop sowing sowing requirement.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A-A profile of Fig. 1.
Embodiment
As Fig. 1～shown in Figure 3, the horizontal circle disc type precise sowing seeding unit of present embodiment, pushed away part such as kind of bar 8 by seed-box 2, rotating shaft 1, seed plate 4, bar shaped hairbrush 3 and elasticity and form, seed-box 2 is the drum shape, is assembled by a ladle body and the bucket end 6 that is shaped on bearing block.Seed plate 4 is rotationally connected by rotating shaft 1 and bearing and seed-box 2, on seed plate 4, be shaped on the toroidal cavity concentric with rotating shaft 1, the inside and outside side of this toroidal cavity is respectively positive round table surface and rounding table top with respect to rotating shaft 1, holds kind of a hole 5 and is arranged on equably on the bottom surface of toroidal cavity along circumference.Bar shaped hairbrush 3 is installed in the top of seed-box 2 seed outlets 7, and brush holder and ladle body are connected, and the length direction of bar shaped hairbrush 3 brushes is tangentially parallel with seed plate 4.Elasticity pushes away kind of bar 8 usefulness spring steel wires and makes, and is installed in bar shaped hairbrush 3 brushes, and its upper end is connected with brush holder, and the bottom curves one can extend into the annulus that holds in kind of the hole 5.
As can be seen from Figure 2, the appearance kind hole 5 of seed plate 4 is a rectangular opening, and the length and width size in this appearance kind of hole 5 can be held the rice paddy seed that two chips with side-by-side lay flat on one's back, long limit and 4 one-tenth arranged tangential of seed plate.
In addition, the rotating shaft 1 of present embodiment extends upward the upper port that passes seeding unit, and the transmission device of sower can be located at the top of seeding unit like this, thereby can reduce the liftoff position of the seed outlet of seeding unit, more helps the accurate cavitation of seed that broadcasts.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
