Abstract

The utility model relates to an agricultural machine, particularly a machine for cutting corn straws and returning the corn straws to the field. A straw pressing bucket is fixed on the front end of a frame, and a root digging shaft which is fixed with a root digging claw is fixed on the frame on the back end of the straw pressing bucket. A cutter shaft which is fixed with a hobbing cutter is fixed on the back end of the frame. The cutter shaft and the root digging shaft are connected with each other through a chain, and are driven by a belt pulley. The utility model has the advantages that both the root and the straw of the corn can be cut up; the matched dynamic force is small; the structure is simple; the processing and the manufacture are easy. The utility model is the replacing product of a corn straw returning machine.

Description

Family's ground multifunctional corn return straw into soil machine

The utility model relates to a kind of agricultural machinery, particularly with the machinery of corn stalk mincing and returning to the field.

The structure of corn stalk field-returning machine is similar at present, and the chopping cutter is that zigzag blade is vertically arranged many, by the high speed rotating or the swing of knife section, the corn stalk chopping is layered on the field.Because corn stalk is very high, it is too low that blade cloth has lacked efficient, so blade can only many cloth several groups, its frame for movement and institute join power and become big, cost improves, and is not suitable for doing small-sized machine, the most important thing is that it can only shred corn stalk ground with top, and just powerless, and can not shred the corn stalk that has fallen down to the ground to corn root.Moreover be to be layered on the ground surface after the corn stalk chopping, make troubles for the later process operation, must deep ploughing just can bury.

The purpose of this utility model is to design a kind of simple in structure, and institute joins that power is little, chopping rate height, can be with the corn stalk field-returning machine of corn root and straw chopping.

The utility model is achieved in that the front end compression column with fixed bucket of frame, in order to corn stalk is pushed over forward, on the frame of bottom, depression bar bucket rear end, by the bearing crosswise fixed axle of uprooting, uproot the diameter of axle to the pawl of fixedly uprooting, uproot the axle an end fixed gear, gears engaged on this gear and the methods, rack fixed thereon, the coaxial sprocket wheel of also fixing of top gear, on a back frame of uprooting, pass through bearing crosswise fixed cutter shaft, one end fixed gear of cutter shaft, the gear that is engaged with also is fixed on the frame, the also coaxial stationary power input of the gear that is engaged with belt pulley, the other end fixed chain wheels and the power input pulley of cutter shaft, sprocket wheel links to each other by chain with sprocket wheel on the axle of uprooting, on the cutter shaft in the frame fixedly 2-6 hobboing cutter, on hobboing cutter front end frame, the fixing quiet cutter that is used with it, the central bottom fixing vehicle wheel of frame, top fixed drive bar, the rear portion is hanger fixedly.

The utility model compared with prior art has following advantage: 1) since the pawl of uprooting work by turns at a high speed, therefore institute to join power little, can make small-sized machine; 2) owing to about it belt pulley is arranged respectively, so four-wheel or hand tractor can use easily; 3) since the utility model be with corn grub out out push over after chopping again, therefore the straw of most of chopping is buried by soil; 4) structure is little, simple in structure, easily processing and manufacturing, and cost is low, is the regeneration product of corn stalk field-returning machine.

Be elaborated below in conjunction with accompanying drawing:

Fig. 2 is the utility model vertical view

Fig. 3 is the utility model charging supporting plate front view

Fig. 4 is the utility model charging supporting plate vertical view

The fixing worker's bar bucket 1 of pressing of the front end of frame 23, in order to corn stalk is pushed over forward, as Fig. 1, shown in 2, on the frame 23 of bottom, depression bar bucket 1 rear end, by the bearing crosswise fixed uproot the axle 10, axle 10 pawls 2 of radially fixedly uprooting of uprooting, the uproot top fixed blade 9 removably of pawl 2,2 nine of the pawls of uprooting are one group, nine uproot pawl 2 cutters, 9 width additions and shared axle 10 equal in length or big slightly of uprooting, 2 three of the pawls of uprooting are a group, adjacent two of each group uproot the pawl 2 of uprooting of two other groups are arranged between the pawl 2, and three of each group pawls 2 of uprooting are close to when digging ground successively, and the pawl 2 of therefore uprooting can all dig mistake ground discontinuously.Fixing charging supporting plate 22 on the following methods, rack 23 of the depression bar bucket 1 and the pawl 2 of uprooting shown in Fig. 3,4, uses when being used for just shredding plant straw or grass.Gear 12 engagements on axle 10 the end fixed gear 13 of uprooting, this gear 13 and methods, rack 23 fixed thereon, the gear 12 coaxial sprocket wheels 11 of also fixing.On the axle 10 back frames 23 of uprooting, pass through bearing crosswise fixed cutter shaft 17, one end fixed gear 20 of cutter shaft 17, the gear 19 that is engaged with also is fixed on the frame 23, the also coaxial stationary power input of gear 23 belt pulley 18, and this belt pulley 18 can drag with four-wheel tractor.The other end fixed chain wheels 16 of cutter shaft 17 and belt pulley 15, sprocket wheel 16 links to each other by chain 10 with the sprocket wheel 11 of axle on 10 of uprooting, and this belt pulley 15 can drag with hand tractor.Fix four hobboing cutters 8 on the cutter shaft 17 in the frame 23, hobboing cutter 8 is inclined to certain angle with its place generatrix direction, to reduce to cut pin power.Hobboing cutter 8 also can all be shredded to guarantee soft straw or maize leaves near removably fixing comb cage 7 on the following methods, rack 23.On hobboing cutter 8 front end frames 23, the removably fixing quiet cutter 21 that is used with it.The central bottom fixing vehicle wheel 4 of frame 23, wheel 4 height are adjustable, top fixed drive bar 3, the rear portion is hanger 5 and backplate 6 fixedly.
