No-tillage fertilizing and seeding machine
Technical field
The utility model relates to a kind of agricultural machinery.
Background technology
Existing a lot of wheat no-tillage fertilizing and seeding machines on the agricultural machinery market, but these machineries are prone to problems such as serious obstruction of stalk and seeding quality difference when corn seeding on unfallowing field wheat.The sower clogging-preventing measures has two kinds usually: a kind of is the driven disk cutter, the breaking disc cutter is installed before plough, under the effect of facility own wt power, bury and cut off stalk and root stubble, be used for external large-scale towed no-tillage seeding machine more, and for domestic, according to China's national situation all is small-sized no-tillage seeding machine mostly, because of this anti-blocking mode of the restriction that is subjected to the less factor of own wt power can not reach the expection ideal effect; Another kind is to drive rotary blade, and the rotary blade breaking promptly is installed before the plough, exist the soil disturbance amount big, be unfavorable for problems such as preserving soil moisture, power consumption are big.
In recent years, some stubble cleaners and sower have occurred on market, operation effectiveness is also good, but they mostly are single homework machinery, need just can finish whole sowing operation in the same plot of sowing, so not only time-consuming but also excessive fuel consumption increases operating cost and misses the sowing best opportunity easily with repeatedly advancing.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of no-tillage fertilizing and seeding machine, occur the problem that stalk stops up serious and seeding quality difference when the crops seeding on unfallowing field crops easily to solve, and need repeatedly just can finish problem such as whole sowing program in sowing during with plot.
The technical scheme that its technical problem that solves the utility model adopts is on the basis of former rotary tillage ferti-seeding machine, be replaced into driver plate cutter (12) driving rotary blade, jagged and the blade of this driver plate cutter (12) design, and become α ° to be welded as a whole with axle sleeve, be arranged in (see figure 2) on the rotation semiaxis by the bolt connection; At the driver plate flank face applicator boot (10) is set, this applicator boot (10) bending keeps certain interval by sticking together with driver plate cutter (12) forward, be fixed on the big frame back rest (9) by U-bolt (8), and sharp spear (see figure 1) be set at its fertilizer outlet place.
Adopting good effect of the present utility model is the maize straw and the weeds on the cutting disc cut-out ground on the power drive cutter shaft, corn stubble is in the ground buried in incision, the spear energy cut-away portions corn stubble that breaking wedge angle plough (being applicator boot) is sharp, the normal pressure that needs is little, has solved feed mechanism and has easily stopped up stifled problem., developed the novel wheat no-tillage fertilizing and seeding machine that one-stop operation can be finished breaking, operations such as trench digging fertilising, sowing and suppression by theory and combining is actual like this.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model driver plate cutter assembling schematic diagrames;
1 Cardan shaft, 2 hitch frames, 3 gearboxes, 4 big framves, 5 seed manure casees, 6 roller sealers, 7 double disk openers, 8U type bolt, the 9 big frame back rest, 10 applicator boots, 11 rotation semiaxis, 12 driver plate cuttves, 13 are built furrow plough, 14 depth-control wheels among the figure.
Embodiment
As shown in Figure 1; The utility model Cardan shaft (1), hitch frame (2), gearbox (3), big frame (4), seed manure case (5), roller sealer (6), double disk opener (7), build furrow ploughs (13), depth-control wheel structures such as (14) is same as the prior art, driver plate cutter and applicator boot are the innovation part, each is formed by 12 groups, and applicator boot (10) is arranged at driver plate cutter (12) rear portion.Driver plate cutter (12) is the cutaway disk cutter, by the stamping-out blanking, mill manufacturing procedures such as sword, thermal treatment and be made, and becomes α ° of angle to be welded as a whole with axle sleeve, installs by bolt, dog screw to be arranged in rotation semiaxis (11) and to go up (see figure 2); Applicator boot (10) is to be profiling size bent into shape by round steel pipe with the maximum rotational trajectory of driver plate cutter (12), and welded spear at the fertilizer outlet place, go up (see figure 1) by U-bolt (8) and mounting plate mounting arrangements at the big frame back rest (9) at last.
During operation, outputting power passes to gearbox by Cardan shaft behind the tractor, and by the transmission of case internal gear, cutting disc is with the cutter shaft high speed rotating, when cutting off corn stubble, the wide ditch of 4~5cm can be left, the operation resistance of fertilising thereafter and seed opener can be effectively reduced.Roller sealer drives fertilizer, dispenser by drive sprocket and chain, to realize fertilising and to sow.My company has also designed applicator boot especially, and it is close to driver plate, in case have root stubble, weeds to hang on the plough, rotation that can be by the driver plate cutter is with its cut-out and throw away, and prevents that like this root stubble, weeds from stopping up stifled before the sowing opener.The cutaway disk cutter is installed on the power drive cutter shaft, with certain rotating speed forward rotation.The driver plate sliding cutting effect of forward rotation is stronger, and sliding cutting speed is to the back lower place, but compressed straw is strengthened support, is more satisfactory cutting mode, leaves the groove of a certain width and certain depth simultaneously.This type soil disturbance when operation is little, has played good no-tillage effect.
