Abstract
The utility model relates to a sowing device, in particular to a sowing device with adjustable row spacing which can not only realize the positioning sowing of row spacing, but also adjust the sowing distance. In order to achieve the purposes of the utility model, the sowing device with adjustable row spacing is mounted in a seed-sowing machine and comprises a drive gear and a driven gear, wherein the drive gear is mounted at one end of the front rotary drum of the seed-sowing machine and is coaxially connected with the front rotary drum; the driven gear is mounted on a frame, positioned on the same side with the drive gear, and is driven by the drive gear through a chain; and the driven gear drives the rolling wheels on the frame so as to allow the sowing wheels on a seeder to rotate. The sowing device provided by the utility model is characterized in that through the seeder, positioning sowing is realized; and by adjusting the proportion between the number of the drive gear teeth and that of the driven gear teeth, the positioning sowing of the seeder is realized.
Description
Technical field
The utility model relates to a kind of seeding apparatus, the adjustable seeding apparatus of particularly a kind of spacing in the rows.
The utility model also relates to a kind of method of sowing, specially refers to the type of seeding that can adjust spacing in the rows.
Background technology
Existing sower basically all can not be realized the spacing in the rows free adjustment; Generally all be continuous sowing, dibbling on request is because their spacing in the rows can not be located; The seed of sowing so just can not well become alive, particularly needs the growth-gen of spacing for some; Broadcast sowing and be applicable to wheat, and for, present booth vegetable; These vegetables conditions of compatibility are poor, and it is higher to compare for the requirement of sowing, and some peasant household also can some semi-automatic power tools of own utility model; Be exactly in a big cake, the seed of packing into is through the hole of on cake, drilling; By the fixing cake of frame, when the hole forwarded ground to, seed can be fallen in the ground automatically; The sowing of this method is provided with that it is simple in structure, but practicality is strong, versatility is not strong yet, only is suitable for the sowing of portion's part seed; For example; When we will broadcast corn certainly, require a position to put into two seeds or three seeds, carry with this and do its survival rate; The said equipment just can't be realized so, finally still can only the by artificial seeding.So, just gone out an existing picture, the high-end agricultural of China, particularly in recent years booth vegetables in improper season, because the restriction of sowing condition, the restriction that sowing requires, people still can only handwork, can't realize automation, mechanization.
The utility model content
The utility model purpose of the utility model is: a kind of seeding apparatus is provided, and it not only can realize the positioning planting of spacing in the rows, and the distance of sowing is adjustable.
For accomplishing the utility model purpose, the utility model is achieved in that a kind of device of regulating the sowing spacing in the rows, and it is installed on the sower; Comprise driving gear, driven gear; Described driving gear is installed on an end of the preceding drum of sower, links to each other with preceding drum is coaxial; Described driven gear is installed on the frame, with driving gear in the same side, and drive by driving gear through chain; Driven gear drives scroll wheel on the frame, and then the seeding wheel that drives on the seeder rotates; It is characterized in that: described seeder can be realized positioning planting, and proportional relation realizes the positioning planting to seeder between the number of teeth through regulating driving gear, the number of teeth of driven gear.
Technique scheme is done further refinement, and driven gear is fixedly mounted on the frame; Coaxial with the axis of rolling on the frame, on the axis of rolling, be provided with travelling gear; Described driving cog is mutually meshing with seeder upper seeding wheel tooth; Said sowing tooth is connected with seeding wheel is coaxial.This programme adopts will be coaxial by the gear and the axis of rolling; On the axis of rolling, be provided with travelling gear; Again with travelling gear and the mutually meshing scheme of seeder upper seeding wheel tooth; These three gears are moved with speed, thereby realize the relation of only definite driven gear and driving gear, just can realize sowing the control of kind of distance.For example, will change five circles when driving gear advances 1 meter, and driven gear is littler than driving gear, it will change last 10 circles, and is such, last 10 circles of the same commentaries on classics of the axis of rolling; And then travelling gear and sowing tooth, and same 10 circles that rotate of seeding wheel; If at this moment on the seeding wheel 5 seed troughs are arranged, that is to say that so sower goes ahead 1 meter, we have sowed 50 seeds between this rice.If more bigger by gear, it has only changeed 6 circles, just between 1 meter, has sowed 30 seeds at us so; So just, can there be purpose to set the spacing in the rows of sowing.
Technique scheme is done further to improve, and described seeding wheel is provided with seed trough, and what seed trough was orderly is arranged on the seeding wheel; Described seeder is provided with a retaining kind of brush going out kind of a mouth place, and retaining kind of brush is with blocking the outer seed of kind of groove; Described seeding wheel is replaceable.Want real the realization and decide the sowing of strain spacing, will control seed so outside broadcasting seeder, therefore, this scheme is provided with a retaining and kind brushes going out kind of a mouth place.When seeding wheel forwards outlet to, block seed by retaining kind of a brush, the seed that does not get into seed trough is stayed in the seeder, prevent the phenomenon of disseminating, and then realize positioning planting.For seed trough can corresponding setting size, plant sowing for needs are two, corn for example, soybean, at this moment the trough groove can be big slightly; Can place two seeds in the groove; For other seed, the seed that survival rate is high can be placed a seed by a seed trough.
Such scheme is done further to improve the proportional relation of seed trough number on the number of teeth of described driving gear, the number of teeth of driven gear and the seeding wheel.This scheme is to the relation between driving gear and driven gear and the seeding wheel, so sowing is accomplished thinner, accurate localization more.
The number of teeth of described driving cog is identical with the number of teeth of seeder upper seeding wheel tooth, can also be through the number of teeth that driving gear is set, the number of teeth of driven gear and the proportionate relationship adjustment spacing in the rows of the kind groove number on the seeding wheel.The proportional relation of the number of teeth of the number of teeth of described driving cog and seeder upper seeding wheel tooth.
The beneficial effect of the utility model is raised labour productivity, is reduced peasant's labour intensity, practices thrift seed, guarantees seeding quality, improves the sowing survival rate, improves field management, reduces production costs.
