Abstract
The utility model relates to a sowing device in agricultural machinery. The utility model provides a seed metering device suitable for fine small-amount sowing of small-particle seed. The seed metering device can arrange the seed in a row for sowing successively. The seed metering device is composed of the following components: a seed charging box, a seed limiting separator plate, a seed discharging separation sheet, a seed charging tank, a seed clearing sheet, a hair brush and a seed clearing slit. The seed charging tank is an annular tank and the seeds can be arranged in a line. The seed limiting separator plate limits the amount of seeds above the seed charging tank, thereby reducing squeezing force bear by the seed and reducing seed injury rate. The seed discharging separation sheet is lower for facilitating seed charging. The hair brush is adopted for reducing seed injury. A gap is provided between the hair brush and the seed discharging separation sheet for reducing shearing force bear by the seed. The seed clearing sheet prevents sowing leakage caused by clamping of the seeds in the seed charging tank.
Description
Technical field
The present invention relates to the seeding apparatus in the agricultural machinery.
Background technology
Precision drilling can reasonably be arranged seed, reaches the saving seed, rationally utilizes soil fertility, sunlight and wind-force, obtains good procreation enviroment, coordinates individuality and group relation, realizes percentage of earbearing tiller height, and the individual plant fringe is many, grain is many, full, thereby reaches aim of high yield.The Precision Seeding culture technique only could put into practice in large area by means of the sower of function admirable.Precision drilling machineryization technology has advantages such as province's kind, saving of labor, energy-conservation, high yield.Wheat is one of China's staple food crop.The wheat cultivation amount of broadcasting is big, spacing in the rows is little, and existing wheat precise seeder is owing to fill the restriction of kind of time, and speed of drilling is low, and percentage of damage is higher, and wheat seeder seeding unit commonly used is fluted-roller feed mechanism now.But since the structure of fluted-roller feed mechanism due to, when seeding quantity more after a little while, seed flow is pulsation phenomenon, uniformity is affected.Therefore, design a kind of mechanical type seeding unit of suitable small-sized seed defective ejaculation amount sowing, plant and be significant for raising seeding uniformity, volume increase, province.This mechanical type dispenser is fit to broadcast the small-sized seed of similar wheat, Chinese sorghum, millet (hybridization millet) etc.
Summary of the invention
The invention provides a kind of dispenser of suitable small-sized seed defective ejaculation amount sowing.This device can be lined up seed a line and sow successively.This device by fill kind of a box, limit kind of dividing plate, a seeding catch, fill kind of a groove, seed cleaning sheet, hairbrush and the clear slit of planting form.
The technical solution adopted for the present invention to solve the technical problems is: kind of the grain weight of groove top is filled in the limit kind dividing plate restriction of filling in kind of the box; Filling kind of groove is a cannelure, and the cross section is circular arc or trapezoidal; Fill in kind of the groove, be uniform-distribution with the seeding catch, the high 1/2-1 of seeding catch times seed width fills the high 1-3/2 of kind of groove times seed width, seeding catch top with fill the gap that there is 1/4-3/4 times of seed width on kind of groove top; Hairbrush stops and to fill the outer seed of kind of groove and discharge seeding unit, hairbrush with fill kind of a groove top and join, gap and the seeding catch top between hairbrush and the seeding catch top is identical with the gap of filling between kind of the groove top; Filling kind of a trench bottom has a narrow annular channel, for the clear slit of planting, plants the slit clearly and passes the seeding catch; Seed cleaning sheet passes in clear kind of slit and fills kind of groove and arrive and fill outside kind of the groove, will fill in kind of the groove seed and derive and fill kind of a groove.
The invention has the beneficial effects as follows: filling kind of groove is a cannelure, seed can be lined up a line; Kind of the grain weight of groove top is filled in limit kind of a dividing plate restriction, reduces the suffered extruding force of seed, reduces the seed seedling-damaging rate; The seeding catch is lower, the easier kind of filling; The employing hairbrush reduces the damage to seed; Hairbrush and seeding catch are gapped, reduce the suffered shearing force of seed; Seed cleaning sheet avoids seed to be stuck in filling forming in kind of the groove broadcast leakage.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing and example.
Accompanying drawing 1 is structure chart of the present invention; Fig. 2 is installation diagram.
1 fills kind of box 2 limit kind of dividing plates 3 seeding catch 4 and fills kind of the groove 5 seed cleaning sheets 6 hairbrush 7 clear slits of planting among Fig. 1.
Embodiment
Fill the part seed in kind of the box (1) in the accompanying drawings owing to be subjected to the effect of gravity, make seed arrive hairbrush (6) and charge into kind of a groove (4) before; The interior seed pressure of kind of a groove (4) is filled in limit kind of dividing plate (2) control; Fill that seed rotates with filling kind of a groove (4) in kind of the groove (4), arrive hairbrush (6) and locate, fill seed in kind of the groove (4) under the thrust of seeding catch (3), with filling kind of a groove (4) by hairbrush (6); Do not enter the seed that fills kind of a groove (4) fully, because the thrust of seeding catch (3) is not enough and the resistance of hairbrush (6), seed is by the slit between seeding catch (3) and hairbrush (6) bottom or slip into the filling in kind of the groove (4) of back, or skids off and fill kind of a groove (4); Seed by hairbrush (6) is derived by the seed cleaning sheet (5) in the clear kind of slit (7) and is filled kind of a groove (4) and sow, and seeding operation is finished.
Claims (3)
1. the dispenser of a suitable small-sized seed defective ejaculation amount sowing, this device by fill kind of a box, limit kind of dividing plate, a seeding catch, fill kind of a groove, seed cleaning sheet, hairbrush and the clear slit of planting form, it is characterized in that: filling kind of groove is a cannelure, the cross section is circular arc or trapezoidal, and filling kind of a trench bottom has a narrow annular channel.
2. the dispenser of a kind of suitable small-sized seed defective ejaculation amount sowing according to claim 1 is characterized in that: fill in kind of the groove, be uniform-distribution with the seeding catch.
3. the dispenser of a kind of suitable small-sized seed defective ejaculation amount sowing according to claim 1, it is characterized in that: the high 1/2-1 of seeding catch times seed width, fill the high 1-3/2 of kind of groove times seed width, seeding catch top with fill the gap that there is 1/4-3/4 times of seed width on kind of groove top.
