Description
Technical field
The present invention relates to a kind of agricultural machinery, especially relate to a kind of small-sized precision seeder.
Background technology
Existing small-sized precision seeder mostly brings realization by sprocket chain for the transmission of travelling wheel and seeding unit, because sprocket chain tape handler takes up space larger, therefore sprocket chain tape handler does not generally install guard shield but directly exposed, like this for working long hours for the precision seeder of slob, the sprocket chain tape handler not having guard shield to screen very easily by muddy blocking, corrosion, thus causes transmission smooth and component wear, the lost of life; Further, exposed sprocket chain band affects the processing safety of machine.In addition, the seeding spacing of the seeding unit that existing precision seeder assembles is determined by the rotating speed of seeding unit main shaft, rotating speed height then seeding spacing is little, otherwise it is then large, and be standardized fixing assembly structure for the sprocket chain tape handler of seeding unit, generally not there is replacing function, therefore finished product precision seeder can only be fixed for the seeding operation of a kind of crop (such as wheat), when needing the seeding operation carrying out another kind of crop (such as corn), the precision seeder for this crop can only be used in addition, the increase of seeding operation cost and resources idle is so caused to waste.
Summary of the invention
The technical problem to be solved in the present invention is: the travelling wheel of existing small-sized precision seeder and the sprocket chain tape handler of seeding unit are easily by muddy blocking, corrosion and cause transmission smooth and component wear, the lost of life, simultaneously, fixing transmission mechanism causes a precision seeder can only be fixed for the seeding operation of a kind of crop, causing seeding operation cost to increase waste with resources idle, providing to solve the problem a kind of transmission mechanism run more reliable and stable and possess the small-sized precision seeder of the seeding operation function of a machine adaptation various crop.
The technical solution adopted for the present invention to solve the technical problems is: a kind of small-sized precision seeder, there is the large frame of body, travelling wheel wheel carrier, trench digging fertilizer applicator and seeding unit, travelling wheel wheel carrier is a pair, lay respectively at the two ends of the large frame of body, the large frame of body and travelling wheel wheel carrier are hollow tubular structure body, run through the large frame inner chamber of body and be provided with main transmission bar, an one-level bevel gear commutation driving member is respectively provided with near the middle part of main transmission bar and end positions, main transmission bar and each one-level bevel gear driving member that commutates matches, one-level bevel gear commutation driving member in the middle part of main transmission bar is fixedly installed on the large frame inner chamber of body, two one-level bevel gear commutation driving members near main transmission bar end positions lay respectively in two travelling wheel wheel carriers, a two-stage bevel gear commutation driving member is also respectively provided with in two travelling wheel wheel carriers, one-level bevel gear commutation driving member in each travelling wheel wheel carrier and the two-stage bevel gear driving member that commutates are in transmission connection by secondary transmission bar, two-stage bevel gear commutation driving member exports travelling wheel wheel shaft, gear is fixedly installed in the medium position side of the large frame of body, also a two-stage bevel gear commutation driving member is provided with in gear, one-level bevel gear commutation driving member in the middle part of main transmission bar and the two-stage bevel gear driving member that commutates in gear are in transmission connection by secondary transmission bar, above-mentioned one-level bevel gear commutation driving member and two-stage bevel gear commutate all each free holder of driving member and to locate two of being arranged on holder by bearing be that 90 ° of bevel gears engaged are formed, seeding unit power transmission shaft is also provided with in gear, seeding unit power transmission shaft is provided with driven wheel, two-stage bevel gear commutation driving member in gear is in transmission connection by the driven wheel of transition gear group and seeding unit power transmission shaft, seeding unit power transmission shaft is connected with the spindle drive of seeding unit by gear driver capable of reversing, be provided with by the engine-driven sprocket wheel be arranged on the large frame of body in one end of described main transmission bar.This precision seeder except engine be that (this sprocket chain tape handler is relatively high in the position of complete machine for sprocket chain V belt translation to the kind of drive of main transmission bar, affected by environment less during operation), all the other kinds of drive are gear drive and are all in machine intimate, therefore stable transmission, reliable, is not easily affected by the external environment.The seeding spacing of the seeding unit that existing small-sized precision seeder assembles is determined by the rotating speed of seeding unit main shaft, rotating speed height then seeding spacing is little, otherwise it is then large, the adjustment that transition gear group in gear and the gear driver capable of reversing between seeding unit power transmission shaft and seeding unit main shaft all can be used for the seeding unit speed of mainshaft converts, thus makes precision seeder realize the function of the seeding operation of a machine adaptation various crop.
Say further, transition gear group in described gear is made up of the in-line gears of several different sizes, the driven wheel of seeding unit power transmission shaft is arranged in a housing with gear shift spanner, gear has upper cover, upper cover is divided into again fixed part and turning part, fixed part coordinates with the intersection of turning part and is formed with the gear groove corresponding with each gear position of transition gear group, above-mentioned gear shift spanner is stuck in one of them gear groove, the driven wheel of seeding unit power transmission shaft with to should certain gears meshing of transition gear group of gear groove.Carry out transmission by selecting the different size gear of transition gear group and can reach the object changing the seeding unit speed of mainshaft, thus enable precision seeder one machine adapt to the seeding operation of various crop.When selecting gear (i.e. " gear shift ") of transition gear group, open the turning part of gear drive box cover, gear shift spanner is allocated in required gear groove, then the turning part covering gear drive box cover is fixed.
Say further, described gear driver capable of reversing forms by shell and by several travelling gears engaged successively that bearing location is arranged in the enclosure again.This gear driver capable of reversing has two slotting axis holes, during use, it can exchange direction (with the large gear turn the small gear or drive gear wheel with pinion), its effect be also in order to transmission seeding unit main shaft and the rotating speed converting seeding unit main shaft with the seeding operation enabling precision seeder one machine adapt to various crop.
The invention has the beneficial effects as follows: this small-sized precision seeder is compared with existing like product, and the transmission mechanism of travelling wheel and seeding unit is not subject to the harmful effect of external environment, run more reliable and stable, the processing safety of machine improves simultaneously; In addition, this small-sized precision seeder possesses the function that a machine adapts to the seeding operation of various crop, achieves " machine is multiple ", thus resources idle can be avoided to waste, reduce the cost of mechanical seeding operation.
