Problems solved by technology

[0005] The purpose of the present invention is to solve the defects of inconsistency in the seeding time of the seed metering device in the prior art and the poor stability of the hole diameter and hole distance caused by the irregular vibration of the seeding machine in the field, and to provide a double suction type hole sowing seed meter. The impeller seed guide device and its use method meet the agronomic requirements of sowing multiple seeds in one hole, and realize the short-term aggregation of multiple seeds twice successively. , the hole spacing is even and stable, and can also be used for fixed-distance sowing of single seed in one hole

Embodiment 1

[0050] Refer to attached Figure 1-10 As shown, a double-impeller seed guide device for internal suction hole sowing seed meter in this embodiment includes a housing 100, a cover plate 200, an inner impeller 130, an outer impeller 210 and a sealing plate 300, and the open end of the housing 100 A sealing plate 300 is fixedly connected, and the cover plate 200 is fixedly connected to the sealing plate 300. A transmission shaft 110 is arranged inside the housing 100. One end of the transmission shaft 110 passes through the housing 100 to connect to the sprocket 120, and the other end passes through the cover plate 200 to connect to the outside. The outer impeller 210 and the inner impeller 130 are located in the housing 100. The transmission shaft 110 passes through the center of the inner impeller 130 and is connected to the inner impeller 130 in rotation. The inner and outer sides of the cover plate 200 are respectively provided with a C-shaped baffle 260 and a retaining ring 2...

Embodiment 2

[0058] Refer to attached Figure 1-11 As shown, the method of using the double-impeller seed guide device of the internal suction hole sowing seed meter in this embodiment is that the external transmission mechanism provides power for the transmission shaft 110, drives the transmission shaft 110 to rotate, and further drives the outer impeller 210 With the rotation of the inner impeller 130, the seeds between the partitions of the inner impeller 130 are transferred to the partitions of the outer impeller 210, and finally slide out from the guide pipe 240 and fall.

[0059] The usage method of this embodiment includes the following steps:

[0060] S100, seeding, the seeds enter the seed chamber 500 of the seed meter through the seeding pipe 230;

[0061] S200, sucking seeds, the socket ring 170 and the suction hole roller 140 rotate at the same time, and the external fan draws the gas in the seed meter chamber from the air outlet pipe 182, so that the air hole group 141 on the...

Abstract

The invention discloses a double-impeller seed guiding device of a systemic hole sowing seeding unit and a using method thereof, and belongs to the technical field of agricultural seeding. The double-impeller seed guiding device comprises a shell, a cover plate, an internal impeller, an external impeller and a seal plate, a C-shaped baffle and a retainer ring are arranged on the inner side and theouter side of the cover plate respectively, a sector-shaped gap is formed in the cover plate, the internal impeller and the external impeller are located on the inner side of the C-shaped baffle andthe inner side of the retainer ring of the cover plate respectively, a seed inlet is formed in the cover plate, a seed inlet pipe is fixedly connected with the cover plate and communicated with a seedinlet, a shaft sleeve is arranged on the outer side of the external impeller, a drive shaft is inserted into the shaft sleeve which is provided with a baffle ring, a gap is formed in the retainer ring on the cover plate and provided with a guiding tube, and the interior of the retainer ring is communicated with the guiding tube through the gap. According to the design, the seed guiding device realizes two times of transient seed gathering of several seeds, after seeding, hole forming of the seeds in a field is good, the distance between the seeds in holes is small, even and stable, and the double-impeller seed guiding device can be also used for fixed-distance seeding of individual seeds in one hole.

Description

technical field [0001] The invention belongs to the technical field of agricultural seeding, and more specifically relates to a double-impeller seed guiding device of a suction-type hole sowing seed metering device and a method for using the same. Background technique [0002] The precision hole direct seeding technology can accurately distribute the seeds in the field according to the required number of holes and hole spacing according to the planting requirements of the crops, which can save the amount of seeding, reduce the field management in the later stage, and help stabilize and increase production. It has been used in rice It is widely used in the sowing field of hole-sowed crops such as corn and cotton. [0003] According to the principle of seed metering, there are mainly two kinds of seed metering devices: mechanical type and pneumatic type. Among them, the seed guide device matched with the pneumatic seed meter mainly includes a seed guide tube and an inverted p...
