Abstract
The utility model relates to an improved suction-assistant structure for a suction seeding device. The utility model comprises seed suction holes positioned on a seed suction disc, wherein, one suction-assistant groove is respectively arranged on the disc wall of the suction disc on the rear part of the working motion direction of each seed suction hole on the seed suction disc, and the groove depth of each suction-assistant groove is between 0.1 mm and 5 mm. As the utility model is provided with the suction-assistant groove on the rear part of the working motion direction of each seed suction hole, after the suction-assistant grooves enter a seed box, one part of seeds which are directly contacted with the suction-assistant grooves can be trapped into the suction-assistant grooves and can move along with the suction-assistant grooves at the same speed and in the same direction; parts of the partial seeds trapped into the suction-assistant grooves, which are exposed out of the suction-assistant grooves, are like lug bosses, and are capable of generating propelling action for the seeds in the front of the parts of the partial seeds trapped into the suction-assistant grooves to make the seeds in the front of the parts of the partial seeds trapped into the suction-assistant grooves move together with the seed suction disc to reduce relative movement speed of the propelled seeds and the seed suction holes on a seed suction disc. Consequently, the moving speed of the seed suction disc can be increased under the precondition that the suction rate is ensured.
Description
Technical field: the utility model relates to the improvement of a kind of precision drilling with air-suction seeding unit, is meant that especially a kind of suction hole of improved air-suction seeding unit helps the suction structure.
Background technology: kind of the speed of getting of air-suction seeding unit is to limit the major technique obstacle of air inhaling type fine sowing machine operating efficiency always, people have found out kind of the speed of getting that various methods improve air-suction seeding unit for this reason, as the patent No. is 01230061.6, the Chinese utility model patent that name is called " improved vertical disk air-suction seeding unit " is exactly to disclose a kind of technical scheme that a telescopic protrusion is helped suction hole absorbed seed in kind of case that is provided with at the suction hole rear, and it can bring up to 0.7m/s even higher by original 0.35m/s with the linear velocity of suction hole on the seeds sucker; But the disclosed technical solution of this utility model exists that parts are many, complex structure, requirement on machining accuracy height and defect of high cost.
The utility model content: the suction hole that the purpose of this utility model provides the improved air-suction seeding unit that a kind of parts are few, simple in structure, requirement on machining accuracy is low and cost is low helps the suction structure.
The purpose of this utility model is achieved in that a kind of suction hole of improved air-suction seeding unit helps the suction structure, comprise the suction hole that is positioned on the seeds sucker, wherein all be provided with one on the dish wall of the seeds sucker at the rear portion on each suction hole working motion direction on the seeds sucker and help the suction groove, helping the groove depth of inhaling groove is the 0.1-5 millimeter.
Help to inhale between groove and the suction hole and can be separated from each other setting.
Help and inhale the setting that also can overlap between groove and the suction hole.
Because the rear portion of the utility model on each suction hole direction of motion all is provided with one and helps the suction groove, when this helps between suction groove and the suction hole is when being separated from each other setting, after this helps and inhales groove and enter kind of case with the suction hole in its place ahead, the seed that is in direct contact with it can partly be absorbed in this and help among the suction groove, and help under the promotion on the recessed edge of inhaling the groove rear portion along with helping at this and to inhale groove and move with identical speed and direction, and part is trapped in and helps the seed of inhaling in the groove to be exposed to help the part of inhaling groove will be as a boss, can produce an impetus to the seed in its place ahead, make it along with seeds sucker together moves, speed of related movement on seed that is pushed with reduction and the seeds sucker between the suction hole, thereby can guarantee under the prerequisite of adsorption rate, improve the velocity of rotation of seeds sucker; When this helps between suction groove and the suction hole is when overlapping setting, after this helps the suction groove to enter kind of case, the seed that is in direct contact with it can partly be absorbed in this and help among the suction groove, and help under the promotion on the recessed edge of inhaling the groove rear portion along with helping at this and to inhale groove and move with identical speed and direction, make the seed that sticked by it and promote and the speed of related movement vanishing between the suction hole, thereby also can guarantee under the prerequisite of adsorption rate, improve the movement velocity of seeds sucker; Show that through actual motion the linear velocity that is provided with suction hole on the seeds sucker of the present utility model reaches 0.7m/s even when higher, still can well inhale kind, and hole rate is less than 2%.When helping when inhaling groove and moving out of kind of case, the seed that is absorbed in wherein can be coming off under the effect of deadweight to fall back among kind of the case, so help the existence of suction groove can not influence follow-up clear kind and seeding operation.
