Description
Technical field
The present invention relates to agricultural mechanical seeders, particularly relate to a kind of pneumatic seeder gearbox.
Background technology
In recent years, along with the application of science and technology development and breeding, so released a kind of new crops pneumatic seeder, this kind sower can reach precision drilling by the adjusting of air inlet system and seed plate, saves the input that breeding reduces cost in a large number.But present pneumatic seeder is in the sowing process, whenever a kind of spacing in the rows to be sowed and corresponding seed tray will be changed, each kind is as comprising all main spacing in the rows (3,4,4.5,5,6,7,8,8.5,9,10,12 cun etc.), then need to prepare 10 above seed plates, if the different (corns of sowing, jowar, soybean, melon seeds etc.) kind, just need 40 the above seed trays and the preservation of will classifying, change the kind chamber that seed tray needs dismounting to link to each other in addition, its process is more loaded down with trivial details, and the distortion of easily colliding with in the preservation process of seed tray, influence seeding quality, increase the seeding operation cost.
Summary of the invention
The technical problem to be solved in the present invention, provide a kind of gearbox that utilizes and regulate the driven axle rotating speed, thereby realize that a seed tray can contain all main spacing in the rows of lid, do not need to change seed tray, the seed tray that only needs to be equipped with corresponding several kinds gets final product, can simplify labour intensity in the sowing process greatly, precision drilling is accurate, reduces the pneumatic seeder gearbox of seeding operation cost.
The technical scheme that adopts is:
A kind of pneumatic seeder gearbox comprises girder, is fixed on two land wheels, two cover aspirations sowing combinations, two seed trays, driving shaft and driven axles of gearbox, the gearbox both sides of girder middle part.Two land wheels are connected the girder two ends by support arm respectively, and the central shaft of land wheel connects driving shaft by the sprocket wheel chain, and two seed trays are in transmission connection on driven axle by bevel gear respectively.
Described gearbox is made up of gearbox body, drive sprocket set, driven chain wheels, chain tensioner frame, gearbox power shaft and output shaft of gear-box, gearbox power shaft and output shaft of gear-box all are supported on the gearbox body by bearings at both ends, drive sprocket set is slidingly connected at the gearbox power shaft, the fixedly connected output shaft of gear-box of driven chain wheels, described driving shaft is installed on the gearbox power shaft, and driven axle is installed on the output shaft of gear-box.Chain tensioner frame is contained on the gearbox body inwall, by being connected of each sprocket wheel on conversion drive sprocket set and the driven chain wheels, changes driving shaft and the driven axle speed ratio that is installed on gearbox through chain tensioner frame tensioner chain.
Above-mentioned gearbox body top is provided with chamber door.
The present invention utilizes gearbox to regulate the driven axle rotating speed, thereby realizes that a seed tray can contain all main spacing in the rows of lid, does not need to change seed tray, alleviates greatly and changes the loaded down with trivial details labour intensity of seed tray, has reduced the seeding operation cost.

Embodiment
A kind of pneumatic seeder gearbox comprises girder 1, is fixed on two land wheels 6, two cover aspirations sowing combinations 8, two seed trays 7, driving shaft 4 and driven axles 3 of gearbox 2, the gearbox both sides of girder middle part.Two land wheels 6 are connected girder 1 two ends by support arm 5 respectively, and the central shaft of land wheel 6 connects 4, two seed trays 7 of driving shaft by the sprocket wheel chain and is in transmission connection on driven axle 3 by bevel gear respectively.
Described gearbox 2 is made up of gearbox body 9, drive sprocket set 15, driven chain wheels 11, chain tensioner frame 16, gearbox power shaft 14 and output shaft of gear-box 10, gearbox power shaft 14 and output shaft of gear-box 10 all are supported on the gearbox body 9 by bearings at both ends, drive sprocket set 15 is slidingly connected at gearbox power shaft 14, driven chain wheels 11 fixedly connected output shaft of gear-box 10, described driving shaft 4 is installed on the gearbox power shaft 14, and driven axle is installed on the output shaft of gear-box 10.Chain tensioner frame 16 is contained on gearbox body 9 inwalls, open the chamber door 12 on the gearbox 9, by being connected of each sprocket wheel on conversion drive sprocket set 15 and the driven chain wheels 11, change driving shaft 4 and driven axle 3 speed ratios that are installed on gearbox through chain tensioner frame 16 tensioner chains 13, constitute a kind of pneumatic seeder gearbox.
Operation principle:
The tractor-drawn sower is advanced, and land wheel 6 drives gearbox power shaft 14 and rotates, by changing gearbox 2 sprocket wheel speed ratios, thereby change output shaft of gear-box 10 rotating speeds, output shaft of gear-box 10 drives seed tray 7 and rotates, and different rotating speeds obtains different distance, realizes multiple spacing in the rows sowing.
