Abstract
The invention belongs to the technical field of design and manufacture of agricultural machinery and particularly relates to a seed taking mechanism of a precision seeder. The seed taking mechanism comprises a circular seed taking mechanism body, wherein positioning and fixing holes are formed in the seed taking mechanism body, and a plurality of seed taking ports are evenly distributed in the periphery of the seed taking mechanism body; two front seed taking nests and two back seed taking pits with inner cambered surfaces are arranged in each seed taking port; the front seed taking pits are connected with the periphery of the seed taking mechanism body through front seed taking pit extension parts, and the back seed taking pits are connected with the periphery of the seed taking mechanism body through back seed taking pit extension parts; the centers of the front seed taking pits are outward, the centers of the back seed taking pits are inward, the front seed taking pits are high while the back seed taking pits are low, and certain equipotential difference exists. The seed taking mechanism of the precision seeder is reasonable in structure, small-seed-spacing precision seed taking can be realized, the working performance is reliable, seeds are discharged smoothly, and the phenomena that seeds are damaged and get stuck are avoided.
Description
Technical field
The invention belongs to the design of agricultural machinery and manufacturing technology field, particularly relate to the Qu Zhong mechanism of a kind of precision seeding machine.
Background technology
At present, mechanical precision hill-drop drill product for putting on market has two big dominant type, one is clipping self-locking seed fetching equipment, another kind is that hole roller formula forces dispenser, although clipping self-locking seed fetching equipment structure is simple, but during its work seed is planted clothing, the cleaning of dust and filterability extreme difference, cannot automated cleaning seed chamber, more seriously clipping self-locking device is very sensitive to speed of drilling, and the speed limit system of broadcasting is too strict, and being unfavorable for sows in spring when robbing, the requirement lost no time in sowing while there is sufficient moisture in the soil.Hole roller formula forces its simple in construction of seeding apparatus, the cleaning capacity of seed chamber is also strong, but due to the type hole bad adaptability to seed, it is necessary to the difference according to seed size, formulating the pass (kind nest) adapted with it, namely kind takes, the kind nest size of seeding, shape should adapt with sowed son.For sowing different types of seed, it is necessary to make the seed wheel of different size kind nest.But the attachment structure of seed wheel and dibbler is more complicated, changes that seed wheel is very inconvenient, take a lot of work, time-consuming, impact sowing work efficiency.And along with the development of modern agricultural technology, the precision drilling under high-density planting pattern is also widely used in agricultural production.
Current clipping self-locking seed fetching equipment and hole roller formula force dispenser when plant from little to a certain extent time just reached the limit, be just difficult to as being intended to further decreased distance.If the most microspecies of current cotton dibbling device are from being typically in 10 cm, less just extremely difficult.
Summary of the invention
The purpose of the present invention: provide the Qu Zhong mechanism of a kind of precision seeding machine, stable work in work, reliable, do not limited by the kind type sowing seed, all can stablize smart the carrying out measured and sow.Speed of drilling is fast and sows reliable and stable.Be capable of microspecies from take kind, its simple in construction, easy to operate, saving of labor, save time.
Technical scheme: the Qu Zhong mechanism of a kind of precision seeding machine, including being circular Qu Zhong mechanism, arranges location fixing hole in described Qu Zhong mechanism, uniform on the periphery of Qu Zhong mechanism arrange several and takes kind of a mouth；Take be respectively provided with in kind of mouth two there is intrados before take kind of nest and after take kind of a nest；Before take kind of nest and be connected with Qu Zhong mechanism periphery by front taking kind of nest extension, after take and take kind of nest extension after kind of a nest passes through and be connected with Qu Zhong mechanism periphery；Before take kind of a nest and feel resentful and face out, after take kind of a nest and feel resentful towards interior, low after height before the two, there is certain idiostatic.
Preferably, the opening taking kind of mouth described in is partial to setting clockwise or counterclockwise.Preferably, taking the opening of kind of mouth described in, to be partial to the angle of setting clockwise or counterclockwise be acute angle.Preferably, taking kind of nest extension before described, to be smooth cambered design be connected with Qu Zhong mechanism neighboring.Preferably, taking kind of nest extension after described, to be smooth cambered design be connected with Qu Zhong mechanism neighboring.Preferably, take before described kind of nest and after take between kind of nest or closely coupled or interval is connected.Preferably, take after in kind of nest divisible arrange two be connected side by side also there is idiostatic treatment with external measures kind nest and interior take kind of a nest；
Beneficial effect: the Qu Zhong mechanism of this precision seeding machine, it is rational in infrastructure, not only can realize microspecies from smart seed-fetching, and reliable working performance, seeding is smooth and easy, does not have damage seed and seeds-blocking phenomenon.
Accompanying drawing explanation
Accompanying drawing 1 is the main TV structure schematic diagram of invention；Fig. 2 is rearview；Fig. 3 is for taking kind of a schematic diagram；In figure, 1, Qu Zhong mechanism；2, kind of a mouth is taken；3, front kind of a nest is taken；4, kind of a nest is taken after；401, treatment with external measures kind nest；402, kind of a nest is taken in；5, front kind of a nest extension is taken；6, kind of a nest extension is taken after；7, location fixing hole；8, seed.
Detailed description of the invention
Embodiment 1, a kind of precision seeding machine Qu Zhong mechanism, as shown in Figures 1 and 2, including being circular Qu Zhong mechanism 1, described Qu Zhong mechanism 1 is arranged and uniform on the periphery of location fixing hole 7, Qu Zhong mechanism 1 several are set take kind of mouth 2；Take be respectively provided with in kind of mouth 2 two there is intrados before take kind of nest 3 and after take kind of nest 4；Before take kind of nest 3 and be connected with Qu Zhong mechanism 1 periphery by front taking kind of nest extension 5, after take and take kind of nest extension 6 after kind of nest 4 passes through and be connected with Qu Zhong mechanism 1 periphery；Before take kind of nest 3 and feel resentful and face out, after take kind of nest 4 and feel resentful towards interior, low after height before the two, there is certain idiostatic.
The described opening taking kind of mouth 2 is partial to setting clockwise or counterclockwise.The angle that the described opening taking kind of mouth 2 is partial to setting clockwise or counterclockwise is acute angle.Taking kind of nest extension 5 before described, to be smooth cambered design be connected with Qu Zhong mechanism 1 neighboring.Taking kind of nest extension 6 after described, to be smooth cambered design be connected with Qu Zhong mechanism 1 neighboring.Take before described kind of nest 3 and after take between kind of nest 4 or closely coupled or interval is connected.After take in kind of nest 4 divisible arrange two be connected side by side also there is idiostatic treatment with external measures kind nest 401 and interior take kind of nest 402；
In practice, as shown in Figure 3, the arc of the Qu Zhong mechanism of annular takes kind of mouth as seed crawl section (front take kind of a nest), in order to capture seed 8, and with rotate seed 8 is delivered to after take kind of a nest because after take kind of nest and front take kind of nest and deposit an idiostatic in height, seed 8 will be taken advantage of a situation downward landing, thus completing to take kind, the whole process of seeding.
