Description

The stubble cleaner of returning crop stocks to the field

The utility model relates to a kind of farm machinery, relates in particular to a kind of stubble cleaner of returning crop stocks to the field.

Corn stalk also field is to solve the soil organic matter to lack, and the optimization soil structure of improving the soil is improved the ecological environment, and helps increasing production, stablizing the strong approach that increases income.The also field stubble cleaner that uses at present, it is exactly that power consumption is big, efficient is low that a common feature is all arranged, and the root stubble does not have fragmentation, and stubble-cleaning does not have effect, and this is the basic reason that pushes away not open of corn stalk field-returning machine tool so far.

The utility model is developed low-consumption high-efficiency at the problems referred to above, can make corn stalk pulverize also field, the stubble cleaner of again corn stubble being smashed fully simultaneously of returning crop stocks to the field.

The utility model is by front-axle beam, side plate, the rack section that the stationary knife lid constitutes, universal joint, power transmission shaft, gearbox, the column gear transmission case, motivation transfer motion part and cutter shaft that belt drive unit is formed, cylinder, formations such as land wheel, power transmission shaft one end is connected with cardan axis, the other end is mounted in the power intake of gearbox on the frame, two pairs of bevel gears are installed in the gearbox power is divided into two parts, export by left and right sides two-semiaxle, its left side output semiaxis is connected with the drive pulley axle of belt drive unit, right output semiaxis is connected with column gear transmission case axle on being installed in side plate, be the power shaft of column gear transmission case, the output of column gear transmission case is the cutter shaft that blade is installed; The driven pulley of belt drive unit is connected with cylinder is coaxial, reach the stationary knife cover cavity on the cylinder straw reducing mechanism that cooperatively interacts is installed, the preceding bottom of stationary knife lid is the into portion that eats of straw, and rear lower is a Lysimachia sikokiana vent, at the rear portion of frame land wheel is installed.

During the utility model work, tractor dynamic power passes to gearbox through universal joint by power transmission shaft, power is divided into two parts, a part is through the Left Drive gear of gearbox, left side output semiaxis, belt transmission two-stage speedup drive cylinder runs up and pulverizes at the straw that the stationary knife cover cavity will be eaten into, another part power is right travelling gear in gearbox, right output semiaxis, give cutter shaft with transmission of power behind the roller gear case double reduction, cutter shaft and blade low speed rotation are shredded corn stalk root stubble, and the straw after will pulverizing and soil stir evenly, after land wheel rolls, cover and bury, realized stalk crushing and returning and stubble-cleaning purpose.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the also left side view of field stubble cleaner of corn stalk described in the utility model;

Fig. 2 is the also vertical view of field stubble cleaner of corn stalk shown in Figure 1.

Find out that from Fig. 1, Fig. 2 rack section covers 8 (Fig. 1) by front-axle beam 14 (Fig. 2), side plate 10 (figure one, figure two), stationary knife and forms square frame shape structure, hanger bracket 9 is equipped with on front-axle beam 14 right sides, can cooperate with the adjustment plate 2 of land wheel 1, adjust the whole also height of field stubble cleaner.As can be seen from Figure 1 with the coaxial cylinder of driven pulley 5 on the pawl 7 that hangs down is installed, cover 8 inner chambers at stationary knife stationary knife 4 is installed, drive pulley 11 drives stationary knife by driven pulley 5 and covers 8 interior cylinder high speed rotating, the vertical pawl of installing on the cylinder 7 be installed in stationary knife 4 that stationary knife covers 8 inner chambers and cooperate and will cover 8 front lower place straws from stationary knife and eat the corn stalk that portion 6 into eats into and pulverize, the Lysimachia sikokiana vent 12 that is covered 8 back lower places by stationary knife is discharged; Cutter shaft 3 rotating band knife sections 13 are corn stubble chopping, realize the effect of not only chopping and returning but also stubble-cleaning, and the blade of installing on the cutter shaft 3 13 is bending blades.

From the vertical view shown in Figure 2 annexation and the power transmission situation of each parts as can be seen, power transmission shaft 23 1 ends are connected with 15 in universal joint, the other end is the input of gearbox 21, Left Drive gear 20 in gearbox 21, right travelling gear 19 is two pairs of bevel gears, their drive bevel gear is connected with power transmission shaft 23 fixed axis respectively, and driven wheel of differential is exported semiaxis 22 with the left side of gear-box 21 respectively, right output semiaxis 18 fixed axis connect, the other end of left side output semiaxis 22 is fixedlyed connected with the drive pulley 11 of belt drive unit, right output semiaxis 18 is connected with 17 in column gear transmission case on being installed in side plate 10, it is the power shaft of column gear transmission case 17, the output of column gear transmission case 17 is cutter shafts 3 that blade 13 is installed, on the coaxial cylinder 16 of driven pulley 5 several vertical pawls 7 are installed, cover the stationary knife 4 that 8 inner chambers install with stationary knife during work and match.

During work, the power of tractor is passed to gearbox 21 by universal joint 15 through power transmission shaft 23, and Left Drive gear 20, right travelling gear 19 are divided into two parts with power in gearbox 21; Left Drive gear 20 drives the left side output semiaxis 22 of fixedlying connected with it and rotates, making the drive pulley 11 that is fixed on left side output semiaxis 22 drive driven pulley 5 by belt rotates, the number of teeth of the drive bevel gear of Left Drive gear 20 is more than the number of teeth of driven wheel of differential, realize the one-level speedup, the diameter of bel-drivenn drive pulley 11 is greater than the diameter of driven pulley 5, realize the secondary speedup, thereby make cylinder 16 high speed rotating coaxial with driven pulley 5; The number of teeth of the drive bevel gear gear ratio driven wheel of differential of right travelling gear 19 is few, the realization one-level is slowed down, the right side output semiaxis 18 of fixedlying connected with the driven wheel of differential axle sends power to deceleration column gear transmission case 17, realize double reduction, drive cutter shaft 3 and blade 13 with 340 rev/mins of low speed rotation, blade 13 4--5cm that buries is with the crop root residue fragmentation, and will pulverize back stalk and soil and stir evenly, after rolling, plays land wheel 1 effect of burying of covering.

The above-mentioned machine for returning stalk and cleaning stubble cylinder 16 and the horizontal range 540mm of cutter shaft 3, vertical range is 195mm, the pawl 7 that hangs down is 20mm with stationary knife 4 meshing distances, and is strong to the shear rate of straw, the degradation rate height.
