Abstract
The invention provides a seed metering device on the end wall of a rotary cylinder type seeder. The seed metering device is a hollow box in appearance. A seed inlet communicated with an inner cavity of the rotary cylinder type seeder is formed in the side wall of the box. An anti-leakage dam preventing seeds from leaking out is arranged beside the seed inlet. The lower portion of the inner cavity of the box is provided with a seed outlet channel communicated with the outside. An outflow seed guide dam is arranged on the outer side of the tail end of the seed outlet channel. The seed inlet is larger than seeds which are sown. The seed outlet channel is larger than the seeds which are sown. Compared with a rotary bin type seed metering device and a bucket wheel type seed metering device, the seed metering device is simple in structure, has similar effects and has the advantages that the seeds are not damaged and the seed metering device is not blocked. At present, farmers have already used the rotary cylinder type seeder on a large scale, compared with the rotary cylinder type seeder, seeding precision is much higher, and transformation and upgrading are very easy. Besides, the seed metering device is small in size, can be distributed densely on a manual rotary cylinder type seeder to achieve drilling and yield increasing and can be densely distributed on a power rotary cylinder type seeder to achieve high-speed seeding. The seed metering device has good market prospects.
Description
Technical field
A kind of feed mechanism for seed being used on drum-type seeder end wall relates to seeder field.
Background technology
It is the highest all to there is seeding accuracy in drum-type seeder in the market, and cavitation is poor, the amount of broadcasting instability defect.Broadcast
Planting low precision, when its reason is barrel body rotation, seed stirs in housing cavity, when running into the seed leaking hole on housing wall, not
Directly spill through seeding, few when which results in many during the seed spilt.Particularly equal with seed face when seed leaking hole, just broadcast
When kind device stops, seed can spill in a large number.
Summary of the invention
Before seed broadcasts, set up feed mechanism for seed, improve seeding accuracy.
Technical scheme:
. a kind of feed mechanism for seed being used on drum-type seeder end wall, profile is a hollow box body (7), box side wall has with
Seed inlet (1) that drum-type seeder inner chamber communicates, by seed inlet, there is the leakproof dam (2) preventing seed from spilling, in box body
Bottom, chamber have with the external world communicate go out kind of a passage (5), have kind of a guiding dam (3) outside kind of channel end going out.Seed inlet compares institute
Sowing is big.Go out kind of passage bigger than broadcast seed sizes.
Seed inlet through the distance of inner chamber to opposite less than the length of rice paddy seed.
Seed inlet is more than 4 millimeters, less than 7 millimeters through the distance of inner chamber to opposite.
Going out kind of a channel end cross section is that the length of side is more than 4 millimeters, the rectangle less than 7 millimeters.
. the work process of feed mechanism for seed.Illustrate as a example by sowing Oryza sativa L.: feed mechanism for seed (7) is fixed on drum-type seeder end wall
Upper (Fig. 1, Fig. 2, Fig. 3, Fig. 4), box body inner chamber communicates with rotating cylinder inner chamber through the end wall of seed inlet (1) rotating cylinder (6), and arrow pressed by rotating cylinder
Shown in direction be rotated in a clockwise direction around central horizontal axis (4), feed mechanism for seed along with rotation, Oryza sativa L. in seed inlet forwards rotating cylinder to
During the lower section in seed face, seed flows to seeding.Although at this moment the end of seed channel is positioned at the lower section of feed mechanism for seed, but due to Oryza sativa L.
The length of seed is relatively big, and poor fluidity, is unable to stir any more, does not have substantial amounts of seed and spill in being stuck in narrow space.When
When seed inlet is rotated upwardly into the highest point just above the surface of the seed, seed inlet rotating cylinder side is without seed, in feed mechanism for seed
Near the seed inlet of chamber, seed loses support, is back in rotating cylinder, rests on from seed inlet a small amount of seed (about 1-2 grain) farther out
In feed mechanism for seed, and being in loose condition (of surface), when being rotated further, these seeds flow to outside feed mechanism for seed through going out kind of a passage, and lead to going out to plant
To dam (3) Slideslip, broadcast when going out when kind of a guiding dam turns to lower section.
This feed mechanism for seed injuring-free seed, not card type, seed does not flocks together, and owing to feed mechanism for seed volume is little, can closely arrange relatively
The feed mechanism for seed of big quantity is on the end wall of drum-type seeder, thus realizes the little strain in many caves (drilling) volume increase.
Change and kind of the shape on guiding dam, can shift to an earlier date or postpone the time that seed broadcasts.
Four. accompanying drawing explanation
Fig. 1 is feed mechanism for seed three-dimensional structure diagram；
Fig. 2 is the three-dimensional structure diagram that feed mechanism for seed is positioned on drum-type seeder end wall；
When Fig. 3 is the rotation of drum-type seeder, feed mechanism for seed is in the schematic diagram of diverse location；
Fig. 4 is feed mechanism for seed when being positioned on drum-type seeder end wall, the front view of feed mechanism for seed.
In figure, 1 seed inlet 2-leakproof dam 3-goes out kind of guiding dam 4 rotary shaft 5 and goes out kind of passage 6 rotating cylinder
7 feed mechanism for seeds
Five. detailed description of the invention
Further illustrate the structure of a kind of drum-type seeder below in conjunction with the accompanying drawings.
Embodiment one
.. being used in the feed mechanism for seed on drum-type seeder end wall, profile is a hollow box body (7), box side wall has with
Seed inlet (1) that drum-type seeder inner chamber communicates, by seed inlet, there is the leakproof dam (2) preventing seed from spilling, in box body
Bottom, chamber have with the external world communicate go out kind of a passage (5), have kind of a guiding dam (3) outside kind of channel end going out.Seed inlet compares institute
Sowing is big.Go out kind of passage bigger than broadcast seed sizes.
Embodiment two:
Seed inlet is more than 4 millimeters, less than 7 millimeters through the distance of inner chamber to opposite.
Going out kind of a channel end cross section is that the length of side is more than 4 millimeters, the rectangle less than 7 millimeters.
This feed mechanism for seed is than roll-over formula feed mechanism for seed simple in construction, but has the seeding effect of roll-over formula feed mechanism for seed；Arrange than scoop-wheel
Plant the simple in construction of device, but have injuring-free seed, nonclogging advantage；Although the drum-type seeder structure than current large-scale popularization
Complexity, but significantly improve seeding accuracy, make Man-operated sower Rapid Popularization be possibly realized.The biggest of drum-type seeder at present
Amassing and promote the use of, this feed mechanism for seed has the market prospect of wide expansion.Little additionally, due to feed mechanism for seed volume, simple in construction, drum-type is broadcast
Plant machine sowing number of times weekly can be greatly increased, can be matched with on dynamic power machine, it is achieved sowing at a high speed.
