Abstract

A novel easy-seed-filling seed-metering-wheel device used for the agricultural planter seed-meter device is to make the central line of the seed-filling indent form an angle of fifteen to sixty degrees on the clockwise direction together with the central line of the seed-metering wheel corresponding to the indent center when processing the seed-filling indent on the premises of not changing other structure of the planter so as to increase the valid seed-filling time and the valid seed-filling area, to resolve the seed-missing problem and improve the economic benefit of the planter.

Description

The easy seed-feeding type seed wheel

Affiliated technical field

The utility model relates to a kind of novel seed wheel device that is widely used in the agricultural seeding machine seeding unit, under the prerequisite that does not change other structure of sower, not only can increase effectively to fill kind of the time but also can increase and effectively fill kind of an area, solve kind of the problem of leaking, improve the economic benefit that sower uses.

Background technology

At present, the angle of the seed wheel center line at the nest eye center line of employed nest eye wheel and this place, nest eye center is zero degree on the general hairbrush nest eye wheel seeding unit, and promptly above-mentioned two center lines are [as shown in Figure 1] that overlap.This nest eye center line and seed wheel center line angle are that the seed wheel of zero degree not only makes and is in the best and fills the indent amount amount of kind of position less (having only 3-4), and the aperture area of each nest eye has only π r ²(r is a nest eye radius), except that the best was filled kind of position, kind of the area that effectively fills of nest eye also only was equivalent to the horizontal projected area of nest eye aperture area under current state.Because to fill kind of indent amount order proportion less for the best, it is shorter to cause effectively filling kind of the time, is subjected to effectively filling the restriction of kind of area simultaneously, often causes sowing filling kind of a nest ophthalmorrhea under the speed and filling and then influence and sow efficient and farm machinery service efficiency.

Summary of the invention

For overcome existing fill kind of wheel fill kind of a nest eye effectively fill kind of the time short, effectively fill the little deficiency of kind of area, the utility model provides a kind of novel easy seed-feeding type seed wheel, this seed wheel can not only increase substantially and effectively fill kind of a time (increase the best and fill kind of an indent amount order), and can under the prerequisite that satisfies identical sowing speed, strengthen fill kind of nest eye effectively fill kind of an area, utilize the introducing inclination angle of nest eye simultaneously, seed is introduced the nest eye smoothly, avoid the destruction of seed, solve the broadcast leakage drawback of general seeding unit preferably.

The technical scheme that its technical problem that solves the utility model adopts is: fill kind of a nest eye and add man-hour on seed wheel, make each fill kind of the center line of nest eye and form one 15 °-60 ° identical angle (angle Selection that adds this angle in man-hour can be determined according to classification, shape, size and the sowing speed of seed) [as shown in Figure 2] in the clockwise direction with this pairing seed wheel center line in nest eye center.Because the existence of this angle, make that being in the best fills kind of the indent amount order that fills of kind of position and increase (increasing to 7-8 by 3-4) greatly; Because the existence of this angle, make and fill kind of the opening shape of nest eye on the wheel rim ellipse that more to approach a minor axis be r, directly increased and filled kind of an area; Because the existence of this angle, making each fill kind of nest eye has all increased by one and has helped the high inclination-angle that seed imports the nest eye, both has been beneficial to the gravity that utilizes seed and has imported, and makes seed protected again.

The beneficial effects of the utility model are, directly increase best kind of the indent amount order that fills that fills kind of position on the seed wheel, make that effectively filling kind of the time increases substantially; Strengthened same radius and filled the aperture area of kind of nest eye, also just increased kind of the area that fills of seed wheel at wheel rim; Form favourable seed and import the introducing inclination angle of filling kind of nest eye.Like this, even under the prerequisite that improves the seed wheel rotating speed, also can guarantee to fill kind of an effect, make that therefore sowing, not broadcast leakage become possibility at a high speed.And the utility model only needs to fill the angle that assurance is selected in kind of the operation of nest eye in processing and gets final product, and can not do any change to the structural requirement of former seeder.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is at present general nest eye wheel seed wheel vertical section structural map

Fig. 2 is an easy seed-feeding type seed wheel of the present utility model vertical section structural map

1. the bests are filled kind of a nest eye among the figure, 2. can fill kind of a nest eye, and 3. difficulty is filled kind of a nest eye, 4. fill kind of a nest eye center line, and 5. the seed wheel center line 6. fills kind of nest eye center line and the angle α (15 °-60 °) that forms by the oculocentric seed wheel centreline space of this nest.

Embodiment

In embodiment shown in Fig. 2, because the existence of the angle α [15 °-60 °] (6) that fills kind of nest eye center line (4) and pass through to form between the oculocentric seed wheel center line of this nest (5), making under the identical sowing rotating speed seed in the seeder kind case obtain more the best of more number fills kind of nest eye (1) and can fill kind of a nest eye (2), compare with at present general nest eye wheel seed wheel (Fig. 1), the nest eye also obviously increases at kind of the area that fills that wheel rim forms, difficulty is filled kind of nest eye (3) and is obviously reduced, respectively fill simultaneously kind of nest eye and also form a seed importing inclination angle owing to filling of the existence of kind of nest eye center line with the angle α [15 °-60 °] (6) that forms by the oculocentric seed wheel centreline space of this nest, so both prolonged and effectively filled kind of a time, increased again and effectively filled kind of an area, to guarantee to obtain better to fill kind of an effect.

Claims

1. novel easy seed-feeding type seed wheel device that can be widely used in the agricultural seeding machine seeding unit, it is characterized in that filling kind of a nest eye following of the prerequisite that does not change other structure of sower on seed wheel adds man-hour, make each fill kind of the center line of nest eye and form an identical angle in the clockwise direction with this pairing seed wheel center line in nest eye center, to reach the purpose that increase is effectively filled kind of the time and effectively filled kind of area, solve kind of the problem of leaking.

2. easy seed-feeding type seed wheel according to claim 1, it is characterized in that: each fills angle that kind of the center line of nest eye and this pairing seed wheel center line in nest eye center form an identical angle in the clockwise direction between 15 °-60 °, and concrete angle is according to classification, shape, the size of different seeds and sow speed and determine.
