Abstract
The invention relates to a rotating drum type seeder, which consists of a casing and a rotating shaft, wherein the casing is a rotating body; a seed feeding opening is formed in the casing; a matched cover plate is arranged on the seed feeding opening; seed leaking holes are formed in the casing wall; the rotating shaft passes through a center axial line of the casing and is connected onto the casing; two sides of the seed leaking holes are provided with sliding prevention walls for preventing seeds from sliding. The casing is formed by matching and sleeving a left part and a right part; the sleeved and coincident two-layer casings can oppositely rotate; mutually matched seed leaking holes are formed in the two-layer casing walls; the seed leaking holes are positioned on the same peripheral edge. When the two-layer casings oppositely rotate for 5 degrees, 7.5 degrees and 15 degrees, the number of the seed leaking holes can be converted among 3, 4, 6, 8 and 9. The rotating drum type seeder has the advantages that the structure is simple; the weight is light; the sowing quantity can be adjusted in a stepless way; the sowing plant distance can be adjusted in five gears; the sowing precision is high; the cavitation performance is good; the sowing quantity is stable; the rotating drum type seeder can sow larger seeds such as rice and wheat, and can also sow smaller seeds such as oilseed rapes, sesames and millet.
Description
Technical field
A kind of drum-type seeder relates to sower field.
Background technology
It is not high all to there is seeding accuracy in drum-type seeder in the market, and cavitation is poor, the amount of broadcasting instability, and spacing in the rows regulates the defect of inconvenience.Seeding accuracy is poor, and when its reason is seeder rotation, seed circumferentially slides in inner walls, causes the seed leaking hole be positioned on housing wall uninterruptedly to spill seed.Spacing in the rows regulates inconvenience, is because the number inconvenience conversion of seed leaking hole.
Summary of the invention
Change the distribution of hull shape and seed leaking hole, improve the performance of seeder.
Technical scheme: a kind of drum-type seeder, by housing (2), rotating shaft (1) is formed; Housing is a rotary body, housing has seed loading port (3), seed loading port has supporting cover plate (4), housing wall has seed leaking hole (6); Rotating shaft, through the central axis of housing, is connected on housing; It is characterized in that there is anti-skid wall (5) seed leaking hole both sides.Anti-skid wall energy hinders the seed near seed leaking hole to slide, and the perisporium of the anti-skid wall in seed leaking hole both sides and housing surrounds an annular narrow groove (7).The width of the narrow groove of annular (7) is 1.5 to 2 times of broadcast seed sizes, and the degree of depth is more than 1/3rd of annular narrow groove radius.Such size, can ensure that the seed in narrow groove can not slide.
Housing mates suit by left and right two parts and forms (Fig. 2), and the two-layer housing that suit overlaps can relatively rotate; Two-layer housing wall is all distributed with the seed leaking hole of coupling mutually, all seed leaking holes are positioned on same periphery.Seed leaking hole on two-layer housing wall is by following regular distribution (Fig. 3): outer casing (8) has two groups of seed leaking holes; one group is 6 seed leaking holes; 1st is positioned at top (10), and other is from the 1st, by counterclockwise often rotating 60 degree of one, angle seed leaking holes; be evenly distributed on housing wall; two groups is 8 seed leaking holes, and the 1st is also positioned at top, and other is from the 1st; by counterclockwise often rotating miter angle seed leaking hole, be evenly distributed on housing wall; Internal layer shell (9) there are three groups of seed leaking holes, wherein one group the same with the distribution on outer casing respectively with two groups, another group has 4 seed leaking holes, first is positioned at from top, be rotated counterclockwise 22.5 degree of angles place, all the other 3, from first, are often rotated counterclockwise 90 degree one, are evenly distributed on inner layer case body wall.Form through hole when seed leaking hole on two-layer housing wall is relative, the seed in housing can spill through it, and when staggering, seed leaking hole is in closed state, and seed can not spill.When two-layer housing wall relatively rotates, can change the number of through hole, this just can change spacing in the rows, also can change the length of through hole during rotation, thus changes the grain number of every bunch planting kind.
This distribution of seed leaking hole, relatively rotate two-layer housing wall, can obtain along equally distributed 4 through holes of housing wall, 6 through holes, 8 through hole, three kinds of spacing in the rows respectively: in Fig. 3 state, inner layer case body wall is rotated miter angle in the counterclockwise direction, 8 through holes (Fig. 8) can be obtained, continue to be rotated counterclockwise 15 degree of angles under 8 through hole states, 6 through holes (Fig. 7) can be obtained, continue again to be rotated counterclockwise 7.5 degree of angles, 4 through holes (Fig. 6) can be obtained, turn round 7.5 degree of angles, 15 degree of angles again, may revert back to again 6 through holes and 8 through holes.
Seed leaking hole on two-layer housing wall is by following regular distribution (Fig. 4): outer casing has two groups of seed leaking holes; one group is 6 seed leaking holes; from bottom (11); by counterclockwise often rotating 60 degree of seed leaking holes; be evenly distributed on housing wall, two groups is 9 seed leaking holes, from bottom; by counterclockwise often rotating 40 degree of seed leaking holes, be evenly distributed on housing wall; Internal layer shell there are three groups of seed leaking holes, wherein one group the same with the distribution on outer casing respectively with two groups, another group has 3 seed leaking holes, first is positioned at from bottom, be rotated counterclockwise 15 degree of angles place, all the other 2, by from first, are often rotated counterclockwise one, 120 degree of angles, are evenly distributed on outer casing.
The above distribution of seed leaking hole, relatively rotate two-layer housing wall, can obtain along equally distributed 3 through holes of housing wall, 6 through holes, 9 through hole, three kinds of spacing in the rows respectively: in Fig. 4 state, inner layer case body wall is rotated in the counterclockwise direction 60 degree of angles, 6 through holes can be obtained, continue again to be rotated counterclockwise 5 degree of angles, 3 through holes can be obtained, then continue to be rotated counterclockwise 15 degree of angles, 9 through holes can be obtained, turn round 15 degree of angles, 5 degree of angles again, may revert back to again 3 through holes and 6 through holes.
By above principle, seed leaking hole is pacified Else Rule distribution, can obtain the conversion of corresponding spacing in the rows, concrete grammar repeats no more.
Seed leaking hole is combined (Fig. 5) by size two rectangular openings, and the length direction of holes is all along the circumference of housing wall, and orifice size is long 4mm, wide 3mm, and macropore size is long 14mm, wide 12mm.Macropore can be used to broadcast the large seed such as paddy rice, wheat, and aperture is used for broadcasting the small-sized seeds such as rape.
The course of work of seeder: load appropriate seed (grain weight is no more than the half of vome of shell) in housing, Some seeds enters the narrow groove being arranged in lower, block the seed leaking hole be positioned at below narrow groove, when the housing rotates, the housing wall upwards rotated takes neighbouring seed to eminence, the housing wall rotated takes neighbouring seed to lower, the surface of the seed is formed low early and high after skewed, the seed of eminence rushes at lower, when encountering the through hole running to lower, through hole is blocked after going out Some seeds, crowded in narrow groove, thus produce enough large frictional resistance, seed in narrow groove can not be slided relative to housing wall, This prevents the seed leaking hole be plugged and spill seed because of seed slip around.Each like this through hole often circles, and can only spill a seed, this provides for improved cavitation performance and the precision of sowing.
