Description

A kind of multi-functional seeding unit

Technical field

The utility model relates to the seeding unit that a kind of sower is used.

Technical background

For seeding unit, how making its needs that can adapt to sowing Different Crop seed is the most scabrous problem.Early can drilling again can bunch planting seeding unit be the type hole of on hole sowing wheel, opening some fixed size, open some axial seed distributing grooves on the drilling wheel.Though this seeding unit has satisfied the requirement of drilling and bunch planting, owing to the type hole dimension on its hole sowing wheel is fixed, so amount of seed metering is difficult for regulating.The ZL98202558.0 utility model patent discloses a kind of seeding unit, and it has replaced the type hole with the axial seed distributing groove that meets the bunch planting requirement on hole sowing wheel, thereby the bunch planting amount can be regulated.But this seeding unit can not be regulated the bunch planting spacing in the rows.Therefore the ZL99215487.1 utility model patent discloses a kind of seeding unit, it is by being provided with seed distributing groove and seeding half groove that alternate intervals distributes on hole sowing wheel, the corresponding protruding tooth of length is set on the floral disc that cooperates with it simultaneously, solved the problem of regulating the bunch planting spacing in the rows, but its structure shows complexity slightly.

Summary of the invention

The purpose of this utility model provides a kind of multi-functional seeding unit of broadcasting various crop.

For achieving the above object, the utility model adopts following technical scheme: a kind of multi-functional seeding unit, comprise the seed wheel that is contained in the circular hole of seeds discharging box two side, being sleeved on can be with the floral disc of seed wheel rotation in the circular hole, be fixed on the back-up ring that on the seeds discharging box lateral wall floral disc is played the clamping positioning action, and kind of the hairbrush of scraping that is contained in seeds discharging box antetheca inboard, there are two dividing plates that seeds discharging box is divided into three seeding chambeies, in each seeding chamber seed wheel is housed all, correspondingly respectively on the seed wheel in each seeding chamber be provided with seeding type hole or the type groove that to broadcast different seeds, on the antetheca in each seeding chamber, all be equipped with and scrape kind of a hairbrush.

Described seed wheel has three, is respectively flute profile drilling wheel, hole roller and flute profile hole sowing wheel, and the circumference of hole roller is provided with some uniform seeding type holes.Described hole roller can be made up of two parts, and the circumference of every part is provided with some uniform seedings half hole, and two-part seeding half hole shape is complementary and forms complete type hole; Perhaps forming complete type hole jointly by seeding half hole on seeding half hole and flute profile drilling wheel or the flute profile hole sowing wheel extension on the described hole roller.

Described seed wheel also can be two, be respectively flute profile drilling wheel and flute profile hole sowing wheel, the drilling wheel has an extension mutual group to become hole roller respectively with the hole sowing wheel inboard, the inside circumference of each extension is provided with some uniform seedings half hole, and two-part seeding half hole shape is complementary and forms complete type hole.

Because the utility model has two dividing plates that seeds discharging box is separated into three seeding chambeies, in each seeding chamber, the seed wheel that can sow the Different Crop seed is housed respectively, thereby can be used to sow various crop, only need carry out simple operations, and have advantage of simple structure during the sowing Different Crop.

Embodiment

As Fig. 1, shown in 2,3, there are two dividing plates 10 that seeds discharging box 1 is separated into three seeding chambeies in the seeds discharging box 1, all be equipped with in the seeds discharging box antetheca inboard in corresponding each seeding chamber and scrape kind of hairbrush 2, this hairbrush can be a scrubbing brush, also can be plastics semi arch hairbrush and columniform rolling hairbrush.Flute profile drilling wheel 7, hole roller 5 and flute profile hole sowing wheel 3 are housed in the circular hole of seeds discharging box 1 sidewall, and the seed distributing groove 6 of flute profile drilling wheel 7 is uniform on circumference, and its quantity is 14～23, is used to sow wheat.Match with flute profile drilling wheel 7, be set with in the circular hole of this side seeds discharging box sidewall and can the back-up ring (belonging to prior art, not shown) that floral disc is played the clamping location be housed on the seeds discharging box lateral wall with the floral disc of drilling wheel wheel rotation.Several uniform seed distributing grooves 8 are arranged on the circumference of flute profile hole sowing wheel 3, and its quantity is 3～8, is used to sow peanut, Soybean and Other Crops.In the circular hole of this side seeds discharging box sidewall, be set with and with the floral disc 9 of hole sowing wheel rotation the back-up ring 11 to 9 clamping positioning actions of floral disc be housed on the seeds discharging box lateral wall.Between drilling wheel 7 and hole sowing wheel 3 hole roller 5 is housed, several uniform seeding type holes 4 are arranged on the circumference of hole roller 5, its quantity is 3～6, and the shape in type hole can be circular, oval or other shape that is fit to.As shown in Figure 3, hole roller 5 is made up of left side 5a and right-hand part 5b, about half one have half hole that shape is complementary to form complete type hole respectively.

The hole roller of this seeding unit also can be as shown in Figure 4, and flute profile drilling wheel 7 has an extension 7a to match with hole roller 5, and each forms complete type hole by half hole that shape is complementary on extension 7a and hole roller 5.Also can be as shown in Figure 5, flute profile hole sowing wheel 3 has an extension 3a to match with hole roller 5, and each forms complete type hole by half hole that shape is complementary on extension 3a and the hole roller 5.Again can be as shown in Figure 6, flute profile drilling wheel 7 has an extension 7a, and flute profile hole sowing wheel 3 has an extension 3a, and extension 7a becomes hole roller with extension 3a mutual group, and extension 7a and extension 3a go up each and form complete type hole by half hole that shape is complementary.In addition, hole roller 5 can also be an independently monolithic wheel, no longer illustrates.

This seeding unit is contained on the sower by turning cylinder, and at seeding time, according to the kind of broadcasting crop, the kinds of bank deposits bucket on other two seeding chambeies and sower interleaves overhead gage, only stays a seeding chamber, uses for sowing.During as need sowing wheat, two seeding chambeies, right side are blocked, only stayed seeding chamber, left side, wheat seed is fallen on the flute profile drilling wheel from the kinds of bank deposits bucket like this, sows under the drive of sower turning cylinder.In like manner, when needing the sowing corn, two seeding chambeies of the left and right sides are blocked, seeding chamber in the middle of only staying in the time of need broadcasting peanut, soybean, is blocked two seeding chambeies, left side, only stays seeding chamber, right side.
