Abstract

The utility model relates to a seeder which is mainly and technically characterized in that the utility model comprises a seed leakage pipe which has a seed box and is communicated with the seed box, a rotary shaft with a reverse transmission mechanism, a ditching circular disc of a scribing sheet, a soil folding mechanism which can horizontally swing and a rolling wheel which tightly compacts ditching soil, and the periphery of the ditching circular disc forms the shape of an inverse ba scribing sheet which is inclined outwards. The utility model solves the defects that weeds and sundries can be easily pulled by the ditching mechanism of the existing seeder, and the depth of the seed ditch can not be controlled. Because the utility model is provided with the soil folding mechanism which can horizontally swing and a compaction rolling wheel, the soil moisture of soil can be effectively ensured and is favorable for the germination and the growth of seeders. The utility model can be widely suitable for the seeding work of different crops such as wheat, corn, soybean, etc.

Description

A kind of sower

Technical field:

The utility model belongs to agricultural machinery technological field, relates to a kind of seeding machinery specifically.

Prior art:

The structure of Seeder for crops such as present widely used wheat, corn, soybean comprises the frame that has kind of case and seed kind fistulae, the ditcher mechanism that realization is ditched by self gravitation, and sows the seed kind by power pulling sower.But this sower is because its ditcher mechanism excavates seed kind groove by self gravitation, so the seed kind groove depth of being opened is restive; Its two, after planting realize the compacting operation with dynamic power machines such as tractor pullings roller again, therefore existing the seed kind, to bury soil inhomogeneous, compacting operation effort influence the be unearthed problem of germination of seed kind.

Summary of the invention:

The purpose of this utility model just provides a kind ofly can be controlled the seed kind groove depth and can close the seeding machinery of ditch and compacting automatically.

The technical scheme that realizes the sower that the utility model proposed is: its structure comprises the frame of the seed kind fistulae that has kind of case and be communicated with it, comprise rotating shaft and in this rotating shaft, be fixed with the ditcher mechanism that the garden dish of the herringbone scribing that at least one its periphery casts aside outside being is formed that this ditcher mechanism is realized backwards rotation by the transmission mechanism that connects with rotating shaft being fixed with on the frame.

Its additional technical feature is: be connected with at least one on the described frame and close native device; Close native device and be " II " type, wherein go up whippletree and connect with described housiung separator axle, two ends connect with the flat heart wheel that is anchored in the described rotating shaft respectively; Be connected with the compacting roller on the described frame; Described compacting roller is a bored roll; The barrel of described bored roll is made up of some grid bars.

Sower provided by the utility model is compared with prior art and is had the following advantages: one since this sower fix one can swing close native mechanism, so can equably the native foam of seed groove be put down; Its two owing to after closing native device, dragged a roller compacting roller again, can be with the soil layer compacting of seed kind groove, to guarantee the germination of seed kind; Its three because its ditcher mechanism influences the problem of the uniformity of sowing, and can control the weight of the seed kind groove of opening for the power garden dish of the outer herringbone scribing backwards rotation of casting aside of band so can effectively prevent to sow the time to pull the weeds foreign material.

Fig. 2 a is the structural front view of trench digging garden dish;

Fig. 2 b is the end view of above-mentioned trench digging garden dish.

Embodiment:

Be described in further details below in conjunction with the structure and the operation principle of accompanying drawing sower provided by the utility model;

Be illustrated in figure 1 as the structural representation of sower, promptly include the frame 3 of band kind of case 1 and seed kind fistulae 2, to be fixed with two (can be 1 or 3 to axle on this frame, its quantity determines according to the line-spacing of sow) through the fixing rotating shaft 5 of chain (also can be gear or driving-belt) transmission device 4, its peripheral both sides that are fixed with between homogeneous phase in the rotating shaft shown in Fig. 2 a, b are fastened with if a group is the trench digging garden dish 7 of outer herringbone scribing 6 of casting aside, and wherein transmission device is driven by power set 8 and realizes rotating along the direction of arrow (contrary direction).Be the native device 11 of closing of " II " shape for whippletree 10 integral body bottom axle is fixed with on the crossbeam 9 of frame 3, this last whippletree 16 that closes native device drives by the eccentric wheel 12 that is anchored on rotating shaft 5 two ends to be realized swinging.Connecting its barrel by 13 of connecting rods in addition on frame 3 is the hollow roller 14 (can also select solid roller according to different arable land characteristics) that grid bar 17 is formed, and the transmission mechanism 16 that this roller drives through power set drives its rotation and moves ahead.

The operation principle of above-mentioned sower is: dynamic power machine affects frame 3 to advance through pull bar 15, the transmission device that power set 8 drive rotating shaft (can be gear drive, also can be band transmission or chain drive), rotating shaft drives the trench digging garden and coils 7 backward rotation, periphery is splay scribing and rotates a stroke soil trench digging with rim, the garden direction of arrow, the seed kind of planting in the case falls into the native ditch of being opened through fistulae, close the eccentric wheel drive of native device in rotating shaft and realize swinging the strickling of ditch soil, by the roller that is driven that soil pressure is real again.

An arrangement for adjusting height that is made of montant is arranged between rotating shaft and frame 3 as shown in the figure, can adjust the height of trench digging garden dish as required, to satisfy the needs that the native ditch depth of being opened is fit to different seed kinds.
