Description

Wheat seeder

The utility model relates to a kind of wheat seeder, belongs to a kind of seeding machinery.

Existing wheat seeder, its plough have two types, and a kind of is boots angie type plough; this plough grass easy to hang, sowing needs behind certain area to shut down grass is removed, and loses time; inefficiency, and resistance is big, and supporting traction power is also wanted corresponding increasing.Another kind of plough is the double-disk plough, and it is better than boots angie type plough, but heavy, cost is too high, and the masses are difficult for accepting.The frame of wheat seeder is square substantially at present, and curb girder is straight, and front and back are equally high, and structural strength is poor, and complete machine is raised, and land wheel and the setting separately of suppression roller, complex structure.

The purpose of this utility model be to overcome the weak point in the background technology and provide a kind of rational in infrastructure, handsome in appearance, structural strength is high, plough can hack, do not hang grass, resistance is little, transmission is effective, seed manure gives wheat seeder.

The purpose of this utility model is achieved in that it comprises frame, seed manure case, plough, earth level(l)er, covering device, suppression roller, land wheel etc., its plough is a sliding cutter type, it is made up of two earth separation plates and a sliding cutter, and sliding cutter both sides are connected and fixed with two earth separation plates respectively and are the A font; Frame side members is High back is low before the shape; The suppression roller removably connects with land wheel and is integral; The sprocket wheel at land axle two ends links to each other with sprocket wheel on the support plate of seed manure case two ends by chain, and the sprocket wheel of its end links to each other with fertilizer expelling shaft, and the sprocket wheel of the other end links to each other with feed shaft.

The purpose of this utility model can also realize by following technical measures: the plough in earth banking apparatus and covering device, the outside is with wide setting; Plough is separately fixed on the frame front beam by support arm.

The utility model compared with prior art has following advantage:

1, simple and reasonable, because removably connecting with land wheel, the suppression roller is integral, need not set up the suppression roller, when need not suppressing, sticking heavy slowly drained soil upper seeding wheel can not pull down the suppression roller at any time;

2, because plough is a sliding cutter type, therefore, do not hang grass during sowing, hilling not, weeds etc. when trench digging by sliding lancinate disconnected, simultaneously also can be with the large clod fragmentation, resistance is little, saves time, high efficiency keeps sowing depth unanimity;

3, the sprocket wheel owing to the land axle two ends links to each other with fertilizer expelling shaft with fertilizer expelling shaft respectively, thereby laborsaving, has improved the transmission effect, and realization is planted, nutriment in a fertilizer is executed;

4, be owing to frame side members High back is low before the shape, and suitable frame front lower place is installed earth banking apparatus, earth level(l)er etc. and the structural requirement of suppression roller, covering device etc. is installed at the rear portion, and this frame is handsome in appearance, structural strength is high, can be adapted to various types of seeding machineries;

5, because the plough in earth banking apparatus and covering device, the outside with wide setting, makes it to make full use of the soil near the sowing of the furrow ridge and reach, overcome existing sower limit line-spacing furrow ridge 3-4 centimetre, can not make full use of the defective in soil;

6, because plough is separately fixed on the frame front beam, therefore, easy accessibility in case certain plough damages, only need be pulled down impaired plough replacing and get final product, and can realize the adjusting of line-spacing.

Description of drawings:
