Abstract
A double-shaft grain straw and stubble chopping returning machine comprises a cardan shaft. The top of the cardan shaft is provided with an input shaft protection cover, a suspension bracket assembly is arranged on the upper portion of the input shaft protection cover, the cardan shaft is connected with an intermediate gear box assembly, the intermediate gear box assembly is respectively connected with a side gear box assembly and a belt transmission assembly through a left horizontal shaft and a right horizontal shaft after varying speed, side plates are arranged on two sides of the left horizontal shaft and two sides of the right horizontal shaft, and casings are installed at the bottoms of the left horizontal shaft and the right horizontal shaft. The double-shaft grain straw and stubble chopping returning machine is characterized in that the side gear box assembly drives a front cutter shaft to spin, and the belt transmission assembly drives a rear cutter shaft assembly to spin. The double-shaft grain straw and stubble chopping returning machine has the advantage that the double-shaft grain straw and stubble chopping returning machine adopts a double-cutter-shaft and double-reverse-spin operating mode, the front cutter shaft spins reversely to cut off stubbles, and the double-shaft grain straw and stubble chopping returning machine collects remaining straws and stubbles in operation breadth and conveys the remaining straws and stubbles backward and is strong in cut-off capacity and stable to operate.
Description
Technical field
The utility model relates to agricultural machinery technological field, especially relates to a kind of biaxial type rice and wheat straw root stubble and cuts up and farmland returned machine.
Background technology
General rice and wheat straw mechanization direct returning to farmland has also field dual mode of dry land and paddy field.During dry land, a kind of is to utilize harvest machinery configuration straw chopping apparatus, in results the stalk in the feeding machine is shredded and sheds the field again, finishes the also field operation of stalk, but can not the root stubble that be retained in the field after the harvesting be shredded.In addition, be exactly stalk, the root stubble direct mulching and returning in to soil cultivation after utilizing counter-rotating stubble ploughing, rotary tillage machine to results, but not to the chopping effect of straw stubble; General straw crushing and field-returning machine, the chopping and returnings that are used for hard stalks such as corn, jowar more, it is many with flail knife or hammer pawl to pulverize cutter, mainly rely on form pulverizing such as clashing into, tear, be generally single-shaft variant, it is bad to be used for the rice and wheat straw crushing effect, and stalk, the root stubble that pastes ground also can't be pulverized to lodging, rolling.During the paddy field, paddy-field stubble-embedding commonly used plays facility such as pulp grinder, paddy field driving harrow, can only carry out mulching and returning to stalk, root stubble, but can not shred, and when stalk, root stubble amount were big, field effect can't satisfy agriculture requirement.
The utility model content
For overcoming the problems referred to above, solve rice and wheat straw and root stubble crushing effect problem of poor, the technical solution adopted in the utility model is as follows:
A kind of biaxial type rice and wheat straw root stubble cuts up and farmland returned machine, and comprises Cardan shaft, is provided with the power shaft protective cover at the Cardan shaft top, and power shaft protective cover top is provided with the hanger bracket assembly; Cardan shaft is connected with the idler gear box assembly, and the idler gear box assembly is connected with the belt transmission assembly with the side gearbox assembly respectively by left transverse axis, right transverse axis through after the speed change; In left transverse axis, right transverse axis both sides side plate is housed, case is equipped with in the bottom, it is characterized in that: cutter shaft rotation before described side gearbox assembly drives; The belt transmission assembly drives back cutter shaft assembly rotation.
The cutter shaft assembly is provided with moving knife in the back.
Be provided with stationary knife in the case inside top.
Preceding cutter shaft counterclockwise rotates.
Advantage of the present utility model: adopt the two contrary operating types that revolve of double-pole axle, before the contrary rotary-cut of the cutter shaft stubble of being completely cured, and the stalk of leaving over and the root stubble that have drawn in the working width are carried backward, back cutter shaft adopts straight knife or the tulwar that is fixed on the cutter shaft, also can be its combination, pulverize rice and wheat straw root stubble with the fixing cutter acting in conjunction that is ranked on the hood more, can realize the full dose chopping and returning of rice and wheat straw root stubble, especially can carry out chopping and returning to lodging, the straw stubble that rolls or overwhelm between rut during operation, it is strong to be suitable for ability; Back cutter shaft adopts fixed slim straight knife or the tulwar of putting the first edge on a knife or a pair of scissors, and also can be the combination of straight knife and tulwar, spiral arrangement, and the cut-out ability is strong, and running is steadily.

Embodiment
As shown in Figure 1, 2, 3, a kind of biaxial type rice and wheat straw root stubble cuts up and farmland returned machine, and comprises Cardan shaft 1, is provided with power shaft protective cover 2 at Cardan shaft 1 top, and power shaft protective cover 2 tops are provided with hanger bracket assembly 3; Cardan shaft 1 is connected with idler gear box assembly 4, and idler gear box assembly 4 is connected with belt transmission assembly 12 with side gearbox assembly 5 respectively by left transverse axis 13, right transverse axis 14 through after the speed change; In left transverse axis 13, right transverse axis 14 both sides side plate 7 is housed, case 8 is equipped with in the bottom, it is characterized in that: cutter shaft 11 rotations before described side gearbox assembly 5 drives; Belt transmission assembly 12 drives 10 rotations of back cutter shaft assembly.
Be provided with moving knife 9 at back cutter shaft assembly 10.
Be provided with stationary knife 6 in case 8 inside top.
The rotation counterclockwise of preceding cutter shaft 11.
During operation, tractor drives facility and advances, preceding cutter shaft 11 contrary rotary-cuts are cut, cut soil surface from bottom to top, the root stubble on the face of land is downcut, and the stalk of leaving over and the root stubble that have drawn in the working width are carried backward, enter back cutter shaft assembly 10, at the back moving knife 9 arranged of cutter shaft, can be the straight knife fixed or straight flail knife, the bump of the cutter of arranging on combined type flail knife and the case 86 that is ranked more, tear, under the comprehensive function such as cutting, stalk, the pulverizing of root stubble, and shed ground, finish the full dose chopping and returning of stalk, root stubble.
The above; it only is embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
