Description

Multifunctional seed drill

The multifunctional seed drill that the utility model relates to a kind of sowing, applies fertilizer and carry out simultaneously.

Existing sower can only adapt to traditional drilling or program request generally is single function, large seed and small-sized seed can not same machine operations, and large-scale sower volume is big, can not be with the big or small random variation of plot and tractive force, CN2131279 discloses a kind of " suspension type corn lister ", and suitable especially tractor with small four wheels is sowed corn at field from which wheat has been reaped, reaching a machine turns over, broadcast dual-purpose purpose, it is the triplex row structure, on the suspension frame, be fixed with three adjustable ploughshares of lifting and little an animal-drawn seed plough angle, simple in structure, easy to operate, seeding quality is good, but can not execute seed manure simultaneously, and can only be used to sow big grain such as corn crop.

The purpose of this utility model is to overcome the weak point in the background technology and provides a kind of rational in infrastructure, fertilizer and seed can be sowed simultaneously and are not burnt kind, but but seeding row spacing is adjustable, both program request drillings, the sowing crop be staggered, ventilation and penetrating light is good, the multifunctional seed drill of a tractor serves several purposes.

The purpose of this utility model is that it of realizing like this comprises tractating bar, land wheel, frame, seed-box, kind wheel, suppression roller, transmission mechanism, integral body is the triplex row structure, transmission mechanism comprises driving gear, idler gear, change-speed gearing, sowing gear, driving gear places on the land axle, and idler gear, change-speed gearing place on the intermediate gear shaft, idler gear and driving gear engagement, the sowing gear is 2, places on the seed shaft, respectively with 2 change-speed gearing engagements, be provided with shift fork between the change-speed gearing, fork links to each other with handle by lever, pull bar; Seed wheel is provided with staggered two row holes, is provided with piston in the hole, and the spiral shell tooth is arranged on the piston, and with the adjustable screw engagement on the seed wheel, the hole on adjacent two seed wheels is staggered installs; Tractating bar is provided with the adjusting bolt; Be provided with dividing plate in the seed-box, the corresponding setting of dividing plate with seed wheel.

The purpose of this utility model can also realize by following technical measures: ridge buster, suppression roller are slidingly connected at respectively on the front and back crossbeam of frame.Ridge buster is provided with stay cord, and the stay cord other end is attached to be carried on the plough handle, and the hole on the seed wheel is 12, divides 2 row average interlaced arrangement.Tractating bar is provided with 2 shafts of a cart or carriage.

The utility model compared with prior art has following advantage:

1, rational in infrastructure, can carry out various combination, realize the wide ridge combination of large-scale wide cut sowing, also can realize wide cut ridge combination sowing, large and small ridge cooperates sowing, also can use according to the mechanical engagement of combining form and different dynamic, on the small-sized plot, hillside owing to being furnished with the shafts of a cart or carriage, also available manpower or animal power draw in the row sowing, and it is capable once to broadcast 1-3;

2, because the hole on adjacent two seed wheels is staggered is installed on the seed shaft, thereby the seed of broadcasting in the soil also can be staggered, and anyhow, tiltedly embark on journey, helps plant growth in the future, and ventilation and penetrating light is good, the output height;

3, because the hole size on the seed wheel is adjustable, and top land is provided with ball-and-socket, thereby large seed, small-sized seed all can be sowed, small-sized seed can also be blocked the hole, the sowing of drop pass nest, and sowing, fertilizing amount is adjustable, and spacing in the rows is adjustable, and the spacing in the rows of every row also may be adjusted to the form that little spacing in the rows and big spacing in the rows cooperatively interact;

5, because transmission mechanism has adopted speed change gear, the sowing gear speed is adjustable, and when transferring to when quick, the speed of sowing and pace gap widen, plant with kind between to a certain degree then realize drilling apart from being varied down to, thereby program request, drilling all can;

6, a tractor serves several purposes can be sowed, and can broadcast fertilizer again, and fertile the kind with broadcasting different caves do not burnt kind.
