Abstract
The utility model discloses a sowing barrel with an inner air extractor pulled by a bearing which is mounted on a gas pipe axle connected with an air pump. The gas pipe shaft traverses an air-in taking case and a seed extractor, and then the gas pipe shaft is connected with the air-in taking case. A ratable seed extracting plate is disposed between the air-in taking and the seed extractor. Breather seed-catcher holes are provided on the seed extracting plate. A mulch film-pressing gear is connected with the seed extracting plate via two to four pins. The mulch file-pressing gear is connected with a bearing block via three to six bolts. With non-interruptible suction of the air pump, the barrel rotates consistently and the seed extracting case provides seeds incessantly, achieving continuous operation of seed fetching and spot seeding by inner air extracting. The sowing barrel with an inner air extractor has the advantages of reasonable design, convenient manipulation and utilization, and the sowing barrel with an inner air extractor has the properties of accurate spot seeding, seed-saving and field management-free.
Description
Technical field
The utility model relates to a kind of crop seeding machinery, refers in particular to the used built-in air-sucking type sowing rotary drum of precise spot-sowing on the film caudacoria of shop.
Background technology
Sowing rotary drum be program request on the film critical piece.Seeding machinery is just got kind of the sowing rotary drum of bale-out kind behind the existing film, its advantage is to sow behind the film of shop, back, and shortcoming be do not accomplish that precise sowing, seed consumption are big, increase planting cost, the field management workload is big, it is not suitable for the large tracts of land mechanized.Developing a kind of can the seeding machinery of precise spot-sowing be necessary behind film.
The utility model content
The technical problems to be solved in the utility model provides a kind of built-in air-sucking type sowing rotary drum, this built-in air-sucking type sowing rotary drum with film after the program request cylinder combine with the air-sucking type seed-taking device that can accurate get kind, to reach precise sowing behind the film.
The technical problems to be solved in the utility model is realized by following scheme: built-in air-sucking type sowing rotary drum, drive rotation by bearing, structure comprises the cylinder circle, the press mold wheel, bearing, the cylinder circle is provided with 3～8 ducks and chews, it is characterized in that: described bearing is installed on the tracheae axle, the external air pump of tracheae axle one end, other end connected nut, the tracheae axle passes across air suction casing, get the seed shell and communicate with air suction casing, air suction casing and get the rotating seed dish of getting is housed between the seed shell, get and establishing ventilation on the seed dish and inhale kind of an aperture, described press mold wheel with get the seed dish and link to each other by 2～4 fingers, press mold is taken turns and is linked to each other by 3～6 two bolts with bearing block.
The technical problems to be solved in the utility model also can be realized by following scheme: the below of described air suction casing is provided with breach and communicates with atmosphere.Described Ya Zui communicates with dividing the seed cap assembly.
Operation principle of the present utility model and advantage are: during this built-in air-sucking type sowing rotary drum work, the outer and asepwirator pump of tracheae axle joins; In communicate with air suction casing.By getting ventilation suction kind of the aperture that the seed dish is provided with, the seed of getting in the seed shell can be drawn onto on the aperture.Because the aperture of aperture is slightly less than seed, so seed promptly is attached on the aperture of getting the seed dish.When cylinder rotation walking, press mold wheel, cylinder circle, Ya Zui, branch seed cover, get the also rotation synchronously of seed dish.Cylinder rotates to certain position, and when getting aperture on the seed dish facing to the breach of the no suction in air suction casing below, the seed on the aperture promptly vertically falls at minute seed to cover and during duck chews, and treats that duck chews to bury when opening, and seed promptly falls into the soil and finishes sowing.Asepwirator pump is constantly supplied with suction, and cylinder constantly rotates, and gets the seed shell seed constantly is provided.Like this, just realized that built-in aspiration gets working continuously of kind of program request.This built-in air-sucking type sowing rotary drum reasonable in design, easy for operation possesses the function of finishing precise spot-sowing on the film, saving seed, cancellation field management.

Embodiment
Below in conjunction with accompanying drawing for an embodiment.As shown in Figure 1, this built-in air-sucking type sowing rotary drum is driven by bearing 1 and rotates, and cylinder circle 2 is provided with 4 ducks and chews 3.Bearing 1 is installed on the tracheae axle 4, the external air pump of tracheae axle 4 one ends, other end connected nut 5.Tracheae axle 4 passes across air suction casing 6, get seed shell 7 and communicate with air suction casing 6, air suction casing 6 and get the rotating seed dish 8 of getting is housed between the seed shell 7, get and establish ventilation suction kind of an aperture on the seed dish 8, press mold wheel 9 with get seed dish 8 and link to each other by 3 fingers 10, press mold is taken turns 9 and is linked to each other by 3 two bolts 12 with bearing block 11.Duck chews 3 and communicates with dividing seed cap assembly 13.As Fig. 2, shown in Figure 3, the below of air suction casing 6 is provided with breach 14 and communicates with atmosphere.
Claims (3)
1. built-in air-sucking type sowing rotary drum, drive rotation by bearing, structure comprises cylinder circle, press mold wheel, bearing, the cylinder circle is provided with 3～8 ducks and chews, it is characterized in that: described bearing is installed on the tracheae axle, the external air pump of tracheae axle one end, other end connected nut, the tracheae axle passes across air suction casing, get the seed shell and communicate with air suction casing, air suction casing and get the rotating seed dish of getting is housed between the seed shell, get and establishing ventilation on the seed dish and inhale kind of an aperture, described press mold wheel with get the seed dish and link to each other by 2～4 fingers, press mold is taken turns and is linked to each other by 3～6 two bolts with bearing block.
