Description
Technical field
The utility model belongs to agricultural mechanical field, especially relates to a kind of high speed air-sucking type seed tray that is applicable on the air-sucking type grain seeder seeding unit.
Background technology
The air-sucking type seed tray is the key working part on the air-sucking type grain seeder seeding unit, directly influences the seeding operation performance of air-suction seeding unit.Existing air-sucking type seed tray mostly is dull and stereotyped disk, and the suction hole on it promptly vertically is provided with straight-through circular hole for straight-through borehole structure on the seed tray circumference, and it fills kind of a face circular hole place and is provided with 0.5 * 45 ° of chamfering, and the thickness of general seed tray is 1~2.5mm.In order to make grain seeder realize double-row drilling, the two kind of the many employings of air-suction seeding unit chamber, vertical two seed tray list air chamber structures design.Such air-suction seeding unit can carry out the general sowing of single or double strip, and when double-row drilling, two seed trays are all inhaled kind; When wall scroll was sowed, one of them was planted the chamber and is not filled kind, and such square position leads directly to borehole structure air-sucking type seed tray, owing to inhale kind of a negative pressure value height, when the operation of sower high speed, produce Lou and to inhale and broadcast leakage, make the sower can not the high speed operation, therefore have ineffective problem.Simultaneously, because the Structural Design Requirement of existing air-sucking type seed tray adopts the sheet metal manufacturing, the manufacturing process difficulty is big, and easy deformation gas leakage in the use exists problems such as sowing poor performance, service life be short.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of high speed air-sucking type seed tray that adapts to high speed operation, high efficiency, sowing dependable performance and long service life is provided.According to different instructions for uses, select the high speed air-sucking type seed tray of different model for use, can be used for the wall scroll precise sowing, also can be used for two bar precise sowings.
For achieving the above object, the utility model adopts following technical proposals: high speed air-sucking type seed tray of the present utility model is made up of sowing disk and suction hole, radial equipartition is provided with number row suction hole on the sowing disk circumference, this suction hole is made up of with vertical round tube hole water droplet shape semicircle nest hole, the disk plane direction in described water droplet shape semicircle nest hole is a water droplet shape, the disk vertical plane direction in described water droplet shape semicircle nest hole is semicircle, and the vertical direction that is positioned at this described sowing disk in bottom, water droplet shape semicircle nest hole is provided with vertical round tube hole.
As high speed air-sucking type seed tray of the present utility model, can be that radial equipartition is provided with two row's suction holes on the sowing disk circumference.
As another embodiment of the utility model high speed air-sucking type seed tray,, can also be that radial equipartition is provided with three row's suction holes on the sowing disk circumference.
As further improvement of the utility model, the symmetrical centre axis in described water droplet shape semicircle nest hole with between the vertical round tube hole center circular arc tangential line on the described sowing disk, become a α angle.
After adopting technique scheme, the beneficial effect that the high speed air-sucking type seed tray that the utility model provides has is: owing to be provided with water droplet shape semicircle nest hole in kind of face one side of filling of suction hole, can effectively reduce seeding unit induction chamber negative pressure value, make seed tray inhale kind of a rate height, do not produce and Lou inhale and broadcast leakage, realize the operation of seed tray high speed; Again since the suction hole on the high speed air-sucking type seed tray that provides of the utility model form with vertical round tube hole by water droplet shape semicircle nest hole, the gauge of sowing disk is strengthened, easy to manufacture, also increased wearability, thus the effect of the high efficiency of obtaining, sowing dependable performance and long service life.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Among Fig. 1, shown in high speed air-sucking type seed tray, form by sowing disk 1 and suction hole 2.Radial equipartition is provided with two row's suction holes 2 on sowing disk 1 circumference, in Fig. 3, this suction hole 2 is made up of with vertical round tube hole 4 water droplet shape semicircle nest hole 3, the disk plane direction in this water droplet shape semicircle nest hole 3 is a water droplet shape, the disk vertical plane direction in water droplet shape semicircle nest hole 3 is semicircle, is positioned at these 3 bottoms, water droplet shape semicircle nest hole and is provided with vertical round tube hole 4 in the vertical direction of this sowing disk 1.In Fig. 4, the symmetrical centre axis in water droplet shape semicircle nest hole 3 with between the vertical round tube hole 4 center circular arc tangential lines of sowing on the disk 1, become a α angle.
As shown in Figure 2, provided the another kind of structural representation of the utility model high speed air-sucking type seed tray, radial equipartition is provided with three row's suction holes 2 on sowing disk 1 circumference, can make suction hole 2 quantity increase on the sowing disk 1.
Certainly, also can be provided with single on the sowing disk of the utility model high speed air-sucking type seed tray or number row suction hole,, adopt the seed tray of single suction hole structure, can be used for the wall scroll precise sowing and realize the high speed operation to obtain different seed tray structures; Adopt the seed tray of two rows or number row suction hole structure, can be used for two bar precise sowings and realize the high speed operation.Such conversion all drops within the protection domain of the present utility model.
During use, under seeding unit induction chamber suction function, be positioned at seed of water droplet shape semicircle nest hole suction that suction hole fills kind of face one side, along with the high speed rotating of seed tray, induction chamber is produced in water droplet shape semicircle nest hole, and negative pressure disappears, seed is discharged along the seeding unit grain conductor, sows a seed.
