Description
Technical field
The utility model relates to a kind of reducing mechanism, specifically refers to a kind of straw cutting apparatus with the agricultural crop straw chopping.
Background technology
At present, increasing agricultural crop straw all is directly to pulverize the back also to handle in the field.The machinery that adopts for the farming straw-returning mainly contains two kinds, a kind of is the collecting device that stalk is set in frame the place ahead of field-returning machine, utilize the flail knife of rotation at a high speed that stalk is smashed then, the flail knife of this straw cutting apparatus is unsettled setting, flail knife can not land, therefore also after the operation of field, the root of crops and near the bar portion of root also can stand-down on; And therefore this machinery need supporting more powerful tractor because the device that draws stalk in need be arranged.Another kind is the field-returning machine with stalks cutting, and it is the cutting knife that pumps frame setting, when field-returning machine moves forward under the drive of tractor, stalk is overwhelmed on the ground, and cutting knife is with the stalks cutting of lodging then.But present stalk cutting and returning machine moves up and down at a high speed owing to cutting knife when operation; can make field-returning machine produce violent vibrations; therefore be easy to damage tractor and field-returning machine; even the gearbox transmission that working strength is higher; field-returning machine is to use the life-span also can be not oversize; often break down, need shutdown maintenance.In addition, the weight of present field-returning machine is bigger, needs to use powerful tractor to drive, and tractor below 50 horsepowers is with motionless field-returning machine at all, can only drive the field-returning machine that fabric width is 1.8m with 100 horsepowers tractors.
The utility model content
The utility model technical issues that need to address provide and a kind ofly operate steadily, be not easy to break down, the light straw cutting apparatus with stalks cutting.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of chipping field-returning machine, comprise the frame that is driven walking by tractor, the place ahead, bottom of frame is provided with the pressure roller of regulating height by adjusting bracket, adjusting bracket is arranged on the left and right sides of frame, centre position on the frame rear portion arranges a gearbox that is connected with the dynamic power machine of tractor, respectively there is an output shaft both sides of described gearbox, and the outer end of output shaft is provided with identical drive sprocket; Symmetrically on the frame in gearbox the place ahead, the rear of pressure roller be provided with two bearing blocks, the both sides of each bearing block all are symmetrically installed with eccentric wheel, be socketed with the cutter bar that the lower end is equipped with cutting knife by axle sleeve on the eccentric eccentric shaft, be positioned at two inboard eccentric wheels and be respectively arranged with by movable sprocket near a side of bearing block, describedly be connected with drive sprocket by chain by movable sprocket; Cutting knife is hinged on the rear portion of frame by hinge II, connecting rod, hinge I; Two eccentric eccentric shafts that are installed on the same bearing block become 180 ° to be symmetrical arranged, and are installed in two the inboard eccentric position of eccentric correspondences that are positioned on the disalignment bearing, and two eccentric position of eccentric that are positioned at the outside are also corresponding.
Two cutting knifes that are installed in the inboard are moved up and down simultaneously, and two cutting knifes that are positioned at the outside also can move up and down simultaneously.
Another kind of structure of the present utility model is: comprise the frame that is driven walking by tractor, the place ahead, bottom of frame is provided with the pressure roller of regulating height by adjusting bracket, adjusting bracket is arranged on the left and right sides of frame, centre position on the frame rear portion arranges a gearbox that is connected with the dynamic power machine of tractor, respectively there is an output shaft both sides of described gearbox, and the outer end of output shaft is provided with identical drive sprocket; Symmetrically on the frame in gearbox the place ahead, the rear of pressure roller be provided with two bearing blocks, the both sides of each bearing block all are symmetrically installed with eccentric wheel, be socketed with the cutter bar that the lower end is equipped with cutting knife by axle sleeve on the eccentric eccentric shaft, be positioned at two inboard eccentric wheels and be respectively arranged with by movable sprocket near a side of bearing block, describedly be connected with drive sprocket by chain by movable sprocket; Cutting knife is hinged on the rear portion of frame by hinge II, connecting rod, hinge I; The 90 ° of settings of staggering mutually of the described eccentric position of eccentric that is installed on the disalignment bearing.Make four cutting knifes with 90 ° angle interval like this, contact stalks cutting with ground successively.
Further improvement of the utility model is: each eccentric eccentric shaft has the identical radius of turn of 60～80mm.
Further improvement of the utility model is: described axle sleeve is provided with the oilhole of filling lubricating oil.
Owing to adopted technique scheme, the technological progress that the utility model is obtained is: the utility model is by the sprocket wheel chain drive, not only revolution accurately can not throw switch, and the utility model only adopts a gearbox to export two strands of power simultaneously simultaneously, can guarantee that four cutting knifes can accurately move.Said structure has also been simplified frame for movement, alleviated the overall weight of field-returning machine, use low power tractor can drive the utility model, as use 30 horsepowers tractor easily to drive, the width that width of the present utility model can also be wider than tractor reaches 2.1m; And fuel consumption of the present utility model is less in the operation process, and every mu only need consume 1～1.5 liter of diesel oil, is 1/4～1/3 of other field-returning machine.When being installed in being positioned at two inboard eccentric position of eccentric correspondences, being positioned at two eccentric position of eccentric in the outside also at once on the disalignment bearing, can make two cutting knifes that are installed in the inboard move up and down synchronously and land simultaneously, two cutting knifes that are positioned at the outside also move up and down synchronously and land simultaneously, can guarantee that like this field-returning machine does not produce excessive vibrations.
Two eccentric eccentric shafts on being installed in same bearing block become 180 ° of eccentric position of eccentric that are symmetrical arranged, are installed on the disalignment bearing to stagger mutually 90 ° when arranging, four cutting knifes contact with ground successively in the operation process, cutting knife is minimum with contacting of stalk and ground like this, it is also minimum to be subjected to resistance, also can be less to the vibrations of field-returning machine.
Use same tractor to drive field-returning machine of the present utility model, can make the power of tractor mainly act on cutting knife, the strength of chopping stalk is provided for cutting knife, can go deep into more than the soil 60mm when cutting knife of the present utility model moves downward, therefore yet all choppings of root of crops can not influenced follow-up sowing.The utility model can directly bury stalk chopped in the soil simultaneously, has avoided being dried because being exposed to ground of stalk, can fully keep original nutrient component of stalk, improves the fertility of soil.
The parts of cutting the stressed maximum of stalk field-returning machine are axle sleeve and eccentric shaft, and the oilhole that axle sleeve is provided with filling lubricating oil can provide lubricating oil for axle sleeve and eccentric shaft, to prolong its life-span.
