Abstract
The utility model relates to a machine for crushing stalks and returning the stalks to field. A hanging mechanism uses a hanging shaft (14) as a hinging point to hang a machine frame body (5) on a humper (16) on the front end of a tractor. Power is transmitted by a small belt wheel (13) of a clutch which is fixed on a power output wheel (12), a large belt wheel (10) of the clutch, a transmission belt (7), a belt wheel (6) of a knife roller in order to made the knife roller (4) rotate. The circumference of the knife roller (4) is only provided with one flail knife at the position of a certain angle, and the flail knife is symmetrical with another flail knife on the same cross section. The utility model solves the problems that the pulse vibration of the knife roller is severe and the power consumption is large. In addition, the utility model has the advantages of simple structure, reasonable structure and good working performance.
Description
The utility model relates to a kind of stalk crushing and returning machine of agricultural machinery.
At present, known stalk crushing and returning machine adopts quadric chain and tractor to articulate, the structure more complicated, transmission of power is to rely on Rack Body whereabouts tensioning power transmission belt, Rack Body rises and to unclamp power transmission belt when stopping operation, frequent movement in use, and the power transmission belt rate of tension predisposes to damage, cause axle rotational speed to descend, operational reliability is poor.This stalk crushing and returning machine is on many same angle positions that flail knife are installed in the rotor circumference, and during operation, many on angle position cut corn straw simultaneously to flail knife, impulse oscillation is serious, lateral impact power is big, and power consumption is big, influences the raising of production efficiency.
The purpose of this utility model is to provide a kind of stalk crushing and returning machine, and it is simple and reasonable for structure, and running is steady, and power consumption is little, and transaction capabilities is good.
The purpose of this utility model is achieved in that hanging mechanisms are is that hinge is suspended on Rack Body on the tractor front end bumper with the hitching axis, drive the Rack Body lifting by hinged cover by lifting arm, lifter drawing bar, hanger, power-transmission system is by having the clutch small pulley of fixed position through the big belt wheel of clutch, driving-belt, rotor belt wheel rotor to be rotated with power output wheel, a flail knife only is installed on the position of rotor circumference certain angle, symmetrical with another flail knife on same cross section.
After adopting such scheme, hanging mechanisms are simple, the transmission of power good reliability, flail knife connection and reasonable arrangement on the rotor, solved the serious and big problem of power consumption of rotor impulse oscillation, therefore the utlity model has simple and reasonable for structurely, running is steady, power consumption is little, the good effect that transaction capabilities is good.
Below in conjunction with drawings and Examples the utility model is further specified.

The big belt wheel 11. power bands of 1. lifting arms, 2. lifter drawing bars, 3. hangers, 4. rotors, 5. Rack Bodies, 6. rotor belt wheels, 7. driving-belts, 8. trip(ping) levers, 9. disengaging pawls, 10. clutches 12. power output wheels 13. clutch small pulleys 14. hitching axis 15.U type bolts 16. bumpers 17. hinged covers among the figure
With reference to the accompanying drawings, hanging mechanisms are to be that hinge is suspended on Rack Body (5) on the tractor front end bumper (16) with hitching axis (14), by hinged cover (17) by lifting arm (1), lifter drawing bar (2), hanger (3) drives Rack Body (5) lifting, power-transmission system is by the clutch small pulley (13) of fixed position being arranged through the big belt wheel of clutch (10) with power output wheel (12), driving-belt (7), rotor belt wheel (6) rotates rotor (4), on the position of rotor (4) circumference certain angle a flail knife only is installed, symmetrical with another flail knife on same cross section.Rack Body (5) comprises rotor (4), the power conveying system housing etc. of unifying.The available U-bolt of hitching axis (14) (15) is fixed on the bumper (16) of tractor front end.Clutch small pulley (13) is to pass through trip(ping) lever (8) by the lifting of Rack Body (5) to drive through disengaging pawl (9) with the clutch of the big belt wheel of clutch (10).Trip(ping) lever (8) is fixed on the Rack Body (5), and with the rise of Rack Body (5) or fall and drive disengaging pawl (9), disengaging pawl (9) can make the big belt wheel of clutch (10) be in clutch small pulley (13) and combine or released state.
During operation, the lifting handle of handling on the tractor drives lifting arm (1), lifter drawing bar (2), driving Rack Body (5) by hanger (3) is that hinge drops down onto ground with hitching axis (14), trip(ping) lever (8) makes the large and small belt wheel of clutch (10), (13) combination by disengaging pawl (9), at this moment the power that spreads out of of the power output wheel on the tractor (12) just passes to rotor belt wheel (6) through power band (11), clutch small pulley (13), the big belt wheel of clutch (10), driving-belt (7) and makes rotor (4) high speed rotating, carries out operation.When stopping operation, the lifting handle of handling on the tractor drives lifting arm (1), lifter drawing bar (2), driving Rack Body (5) by hanger (3) is that hinge rises disengaging ground with hitching axis (14), meanwhile trip(ping) lever (8) just separates the large and small belt wheel of clutch (10), (13) by disengaging pawl (9), at this moment the power that spreads out of of the power output wheel on the tractor (12) just through power band (11) till the clutch small pulley (13), the big belt wheel of clutch (10) stops operating, and operation stops.From the above, no matter the utility model carries out operation or stops operation, the position of clutch small pulley (13) and power output wheel (12) does not change, so the problem that causes axle rotational speed decline to influence operational reliability because of power band rate of tension has obtained solution.
For example the utility model 12 is the enforcement of flail knife rotor, on 0 ° of angle position of rotor (4) circumference, install one, another flail knife is installed on the position of 180 ° of angles on the same cross section, two flail knives are symmetrical, a pair of flail knife is installed on the position of 30 ° and 210 ° angles down, four pairs of flail knives on 60 ° and 240 °, 90 ° and 270 °, 120 ° and 300 ° and 150 ° and the 330 ° of angle positions then are installed, and above-mentioned six pairs of flail knives are on rotor (4) length direction and equidistantly distribute.The rotor of this structure (4) is owing to have only a flail knife on the position of circumference certain angle, so have only a flail knife to work in the moment of high speed rotating operation process, impulse oscillation is little, aspect in addition, and then flail knife on the next angle position enters cutting state successively, so rotor (5) stress equalization, and running steadily, power consumption is little, and transaction capabilities is good.
