Abstract
The invention discloses a flat plate type seed metering device of a seeder. By using the flat plate type seed metering device, required seeds or fertilizers can be quantitatively separated under the driving of a seeder transmission device and then fall into the ground along with a guide pipe and a furrow opener after translating by a certain distance in the dropping process so that the aim of quantitatively sowing and fertilizing at fixed positions is achieved. The flat plate type seed metering device is scientific in seed metering principle and has the characteristics of precision in quantification, accuracy in location, infinite efficiency (i.e., the length of the seed metering device is infinite, and innumerable lines of the seeds or fertilizers can be separated once), high seed or fertilizer separation speed, multiple functions (granular substances such as various crop seeds and fertilizers) and random line spacing, line number and length.
Description
Technical field
The present invention relates to a kind of utensil of Quantitative Separation seed of sower, is a kind of flat seeding unit of sower specifically.Belong to agricultural machinery technological field.
Background technology
How with seed and fertilizer Quantitative Separation out the key problem of sower is, then also wants positioning planting in ground.For this reason, since several thousand, the mankind have spent a large amount of painstaking effort, invent the sower of numerous types, yet are all owing to not finding suitable seed feeding method to run its course.At present using in the world more sower is the column type seeding unit, and it is by chain-gear transmission device, the rotation motion of land wheel to be become rotatablely moving of seeding unit.This seeding unit is provided with several kinds nest that differs in size, so that the seed of sowing different-diameter, plants nest and admits seed up the time, plants nest and leaves seed behind down the time, reaches the purpose of quantitatively positioning planting.But there are the following problems for it:
1. quantitatively inaccuracy because this seeding unit is cylinder, is planted the nest mouth and is the shape of a saddle, causes the spherical shape seed to fit with kind of nest, and non-spherical shape seed more can't be fitted, thereby causes quantitative inaccuracy, goes back on the contrary easily scratch seed;
2. inconvenient adjusting planting distance, the gearratio of its land wheel and gear is certain, and spacing in the rows is just fixed, wants to change spacing in the rows, just must change different gear width;
3. function is few, and as the fine grain crop of sesame, rape, vegetables and so on, it is helpless so far; Even it is multi-functional that it can be accomplished, yet different crops are also obviously irrational with same spacing in the rows.
4. waste seed, its girth is almost 1/3rd of corn plants distance, thereby will waste 2/3rds seed.Also want in addition spended time to go thinning.
In addition, utility model patent---multifunctional quantitatively positioning planting and fertilizing machine, the patent No. is: ZL 20,072 0086516.8, what adopt is pull bar-rocker-arm transmission device, the shift fork that is arranged on seeding unit can make the seeding unit torsional deformation, causes Lou kind of phenomenon, unfavorable use.
Scientific for the ease of using, strengthening, the present invention pulls seeding unit with cable wire, thereby has eliminated the moment of torsion on the seeding unit and leaked kind of a phenomenon.
Summary of the invention
The invention provides a kind of flat seeding unit of sower, it is characterized in that: the longitudinal and transverse cross section of seeding unit is rectangle; One end is provided with the hole that connects cable wire, hole, middle part that the other end is provided with linking springs and is provided with N 〉=1 feed outlet or fertilizer hole.
The invention has the beneficial effects as follows: seeding unit can be discharged the particulate materials such as various crop seeds and fertilizer fast under the pulling of cable wire-pulley-type transmission device, realize quantitatively positioning planting and fertilising.
Description of drawings
Below in conjunction with accompanying drawing, the present invention is elaborated:
Accompanying drawing is schematic diagram of the present invention.
Embodiment
The flat seeding unit of sower is the strip member of being made by sheet material horizontal, that the longitudinal section is rectangle; One end is provided with the hole that connects cable wire, and the other end is provided with the hole of linking springs, and the middle part is provided with N 〉=1 feed outlet or fertilizer hole.
Claims (2)
1. the flat seeding unit of a sower, it is characterized in that: the horizontal stroke of flat seeding unit, longitudinal section be rectangle (namely with sheet material make rectangular), one end is provided with the hole of linking springs, and the other end is provided with the hole that connects cable wire, and the centre is provided with N 〉=1 feed outlet.
2. the flat seeding unit of sower according to claim 1, it is characterized in that: theoretical length is endless, can intercept arbitrarily as required; The diameter of thickness=seed ± 1/3, thereby can sow various crop seeds and particulate material; In the time of the 1-3 of the diameter=seed diameter of feed outlet times, can discharge respectively 1,2,3,4,5,7 seed, can be according to the agriculture requirement of different crops, the specification of choosing any one kind of them.
