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 is not generally installed guard shield but is directly exposed, like this for working long hours for the precision seeder of slob, there is no sprocket chain tape handler that guard shield screens very easily by muddy obstruction, corrosion, thereby cause the smooth and component wear of transmission, the lost of life; And exposed sprocket chain band affects the processing safety of machine.In addition, the seeding spacing of the seeding unit assembling on existing precision seeder is determined by the rotating speed of seeding unit main shaft, seeding spacing of rotating speed height is little, otherwise large, and be standardized fixing assembly structure for the sprocket chain tape handler of seeding unit, generally do 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), in the time that needs carry out the seeding operation of another kind of crop (such as corn), can only use in addition the precision seeder for this crop, so cause increase and the resources idle waste of seeding operation cost.
Summary of the invention
The technical problem to be solved in the present invention is: the sprocket chain tape handler of the travelling wheel of existing small-sized precision seeder and seeding unit is easily caused the smooth and component wear of transmission, the lost of life by muddy obstruction, corrosion, simultaneously, fixing transmission mechanism causes a precision seeder can only be fixed for the seeding operation of a kind of crop, to cause seeding operation cost to increase and resources idle waste, to provide a kind of transmission mechanism operation more reliable and stable and possess the small-sized precision seeder that a machine adapts to the seeding operation function of various crop in order addressing the above problem.
The technical solution adopted for the present invention to solve the technical problems is: a kind of small-sized precision seeder, there is large of body, travelling wheel wheel carrier, trench digging fertilizer applicator and seeding unit, travelling wheel wheel carrier is a pair of, lay respectively at the two ends of large of body, large of body is hollow tubular structure body with travelling wheel wheel carrier, run through large inner chamber of body and be provided with main transmission bar, near the middle part of main transmission bar and end positions, be respectively provided with an one-level bevel gear commutation driving member, main transmission bar matches with each one-level bevel gear commutation driving member, the one-level bevel gear commutation driving member at main transmission bar middle part is fixedly installed on large inner chamber of body, near two one-level bevel gear commutation driving members main transmission bar end positions lay respectively in two travelling wheel wheel carriers, in two travelling wheel wheel carriers, be also respectively provided with a secondary bevel gear commutation driving member, one-level bevel gear commutation driving member in each travelling wheel wheel carrier and secondary bevel gear commutation driving member are in transmission connection by secondary transmission bar, secondary bevel gear commutation driving member output travelling wheel wheel shaft, medium position one side large of body is fixedly installed gear, in gear, be also provided with a secondary bevel gear commutation driving member, secondary bevel gear commutation driving member in one-level bevel gear commutation driving member and the gear at main transmission bar middle part is in transmission connection by secondary transmission bar, all each free holders and locate two of being arranged on holder by bearing and be 90 ° of bevel gears formations that engage of above-mentioned one-level bevel gear commutation driving member and secondary bevel gear commutation driving member, in gear, be also provided with seeding unit power transmission shaft, on seeding unit power transmission shaft, be provided with driven wheel, secondary 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 being arranged on large 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 the transmission of sprocket chain band to the kind of drive of main transmission bar, affected by environment less when operation), all the other kinds of drive are gear drive and all in machine intimate, therefore transmission is stable, reliable, is difficult for being affected by the external environment.The seeding spacing of the seeding unit assembling on existing small-sized precision seeder is determined by the rotating speed of seeding unit main shaft, seeding spacing of rotating speed height is little, otherwise large, gear driver capable of reversing between transition gear group in gear and seeding unit power transmission shaft and seeding unit main shaft all can be used for the adjusting conversion of the seeding unit speed of mainshaft, thereby makes precision seeder realize the function that a machine adapts to the seeding operation of 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 upset portion, fixed part coordinates and is formed with the gear groove corresponding with each gear position of transition gear group with the intersection of upset portion, above-mentioned gear shift spanner is stuck in one of them gear groove, and the driven wheel of seeding unit power transmission shaft engages with certain gear of the transition gear group to should gear groove.Can reach by selecting the different size gear of transition gear group to carry out transmission the object that changes the seeding unit speed of mainshaft, thereby make precision seeder can a machine adapt to the seeding operation of various crop.While selecting the gear (i.e. " gear shift ") of transition gear group, the upset portion that opens gear drive box cover, is allocated to gear shift spanner in required gear groove, then the upset portion that covers gear drive box cover is fixed.
Say further, described gear driver capable of reversing is located and several travelling gears that engage successively are in the enclosure set are formed by shell and by bearing again.This gear driver capable of reversing has two slotting axis holes, when use, it can exchange direction (with the large gear turn the small gear or drive gear wheel with pinion), and its effect is also for transmission seeding unit main shaft and converts the rotating speed of seeding unit main shaft so that precision seeder can a machine adapts to the seeding operation of 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, move more reliable and stablely, simultaneously the processing safety of machine improves; In addition, this small-sized precision seeder possesses the function that a machine adapts to the seeding operation of various crop, has realized " machine is multiple ", thereby can avoid resources idle waste, reduces the cost of mechanical seeding operation.
