Abstract

The utility model relates to a field returning machine for pulverizing cornstalk and cleaning stubble. Two vertical moveable cutter shafts arranged in a pulverization box are connected with and drive a main shaft through angular wheels, moveable cutters are installed on the moveable cutter shafts, fixed cutters are arranged on the part of the rear wall of the pulverization box, and the part of the rear wall of the pulverization box is corresponding to the moveable cutters; moveable cutters extend from the pulverization box, and a miniature horizontal rotary cultivator is installed on the rear lower part of the pulverization box. The utility model not only can pulverize cornstalk but also can clean stubble; field returning efficiency is high, power consumption is small, and the utility model can be matched with small four-wheel tractors of 15 horsepower, 17 horsepower and 18 horsepower.

Description

Corn stalk is pulverized, the stubble-cleaning field-returning machine

The utility model belongs to a kind of machinery of returning crop stocks to the field, particularly a kind of to corn stalk pulverize, the field-returning machine of stubble-cleaning.

Chinese patent CN2073653U " the vertical cracker of returning crop stocks to the field ", it is that existing horizontal type field-returning machine is transform as vertical field-returning machine, movable arbor and ground are perpendicular, avoided like this owing to blade may screw in the defective of bringing among the earth, increase the weight of breaks down, efficient reduction etc. as load.Has the advantage that cutter life is long, efficient is high.But this machine has only a movable arbor, and moving knife do not stretch out crush box, in the corn stalk screw-in machine, causes careless omission easily not too easily, and chopping and returning is incomplete, and in addition, this machine does not have the stubble-cleaning function, therefore can only pulverize not stubble-cleaning, can not satisfy actual needs.

The purpose of this utility model provide a kind of can crushed straw again can stubble-cleaning, and straw is pulverized corn stalk field-returning machine completely.

For achieving the above object, the technical solution adopted in the utility model is: a kind of corn stalk is pulverized, the stubble-cleaning field-returning machine, vertical movable arbor in the crush box is connected transmission with main shaft by angular wheel, moving knife is installed on the moving axis, the crush box rear wall is equipped with stationary knife corresponding to the position of moving knife, said movable arbor is two, and moving knife stretches out crush box, at the rear lower of crush box miniature horizontal rotary tiller is installed.

Moving knife on movable arbor has 4-15, correspondingly, also be that 4-15 is individual corresponding to the stationary knife of a movable arbor.The rotary blade of rotovator is a straight knife.Crush box each side has a dodge gate, and its upper end flexibly connects with crush box.

Because the utility model adopts two moving movable arbors, the moving knife of right quantity is installed on the movable arbor, the crush box rear wall is equipped with the stationary knife identical with moving knife quantity with the moving knife opposite position, two all direction rotations in machine of movable arbor, extension by moving knife is involved in crush box to corn stalk, and moving knife, stationary knife match, and straw is pulverized, use very convenient, the efficient height.Simultaneously, rotovator work chopping root stubble because rotary blade is a straight knife, makes moving knife consumption be reduced to bottom line.

Further specify the utility model below in conjunction with accompanying drawing and by embodiment:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is a left view of the present utility model.

Embodiment: as shown in the figure, rack-mounted two movable arbors 1 link and transmission by angular wheel with main shaft 2, and moving knife 3 is installed on the movable arbor by helix, and it is 4-15 that moving knife stretches out the crush box number, is preferably 8-13.Corresponding to the position of movable arbor two cuttves 4 that are ranked are installed at the crush box rear wall, quantity is identical with moving knife quantity.At crush box 5 dodge gate 6 is arranged each side, its upper end is hinged with crush box, and the effect of dodge gate is that the straw of avoiding having pulverized flies upward everywhere.Rear lower at crush box 5 is equipped with miniature horizontal rotary tiller 7, and rotary blade 8 is a straight knife, to reduce power consumption to greatest extent.During specific design, be no more than 5cm as long as guarantee the embedded depth of rotary blade, the partial-length that buries is no more than 30cm (can remove two row corns of ridge back dibbling) and get final product, can rive five fresh ideas of root stubble like this or root fibrous root is on every side removed, and is unlikely again to leave big pimple and influence sowing.The utility model can mate with 15,17,18 horsepowers of tractor with small four wheels.

During use, the utility model front overhang is hung on the tractor with small four wheels, the power output wheel of diesel engine is given belt pulley 9 by belt with transmission of power, and belt pulley 9 is given

belt pulley

10 and 11 with transmission of power, thereby drives movable arbor and rotovator work.When tractor advanced, under the cooperation of grain lifter 12, all the moving knife on two movable arbors that inwardly rotate involved in corn stalk in the crush box, and from top to bottom moving, stationary knife cooperate stalk crushing and returning, and rotovator shreds the root stubble simultaneously.

Claims

1, a kind of corn stalk pulverizing, stubble-cleaning field-returning machine, vertical movable arbor in the crush box is connected transmission with main shaft by angular wheel, moving knife is installed on the moving axis, the crush box rear wall is equipped with stationary knife corresponding to the position of moving knife, it is characterized in that, said movable arbor is two, and moving knife stretches out crush box, at the rear lower of crush box miniature horizontal rotary tiller is installed.

2, field-returning machine as claimed in claim 1 is characterized in that, the moving knife on movable arbor has 4-15, correspondingly, also be that 4-15 is individual corresponding to the stationary knife of a movable arbor.
