See also Figure 12 to Figure 15, clamp mechanism 7 is exercisable to make chuck 71 mediate fixing to axial clamped position of axle 5 and the off-position that moves to axial with jackshaft 5.Clamp mechanism 7 comprise be placed on the jackshaft 5 to the chuck 71 of working shaft 61 axial limitings be positioned at the stopper slot 52 on the jackshaft 5.This clamp mechanism 7 has two states, and first state is that stopper slot 52 combines with chuck 71, chuck 71 butt work packages 6; Second state is that stopper slot 52 breaks away from chuck 71, and chuck 71 work package 6 relatively slides.
Special, snapping in and withdraw from for ease of chuck 71, the cross section of this stopper slot 52 is smooth arc.
Special, the number of regulating work package 6 for ease changes loosenning tiller 100 disposable scopes of loosening the soil, and above-mentioned stopper slot 52 has a plurality of along jackshaft 5 axial distribution, and the spacing of this stopper slot 52 is the integral multiple that work package 6 occupies jackshaft 5 length.
Through flexible member 713 is set, chuck 71 can be automatically reset to spacing state from spacing disarm state.Concrete, inner sleeve 711 radially indent forms a groove 7113.Stop part 715 snaps in the groove 7113 of inner sleeve 711.Flexible member 713 is arranged at 715 of boss 7121 and stop parts.When making boss 7121 compression elastic elements 713 through outer sleeve 712 application of forces, boss 7121 leaves over against the position of passage 7112, and after this forces, boss 7121 is reset to over against the position of passage 7112 under the effect of flexible member 713.In the embodiment, flexible member 713 is springs, and an end is resisted against boss 7,121 one sides, and the other end is resisted against stop part 715.
The end face of the working shaft 61 in the limited work package 6 and the distance of stopper slot 52 are more than or equal to the distance of limit element 714 with flange 7111, so that chuck 71 restraint of labour axles 61 move axially.
Above-mentioned limit element 714 can be elements such as ball or pin.
Based on above-mentioned concrete embodiment, loosenning tiller 100 operation principle that is in electric model in the face of loosenning tiller 100 of can under manual or electronic pattern, working down elaborates.
Jackshaft axis X and working shaft axis Y can be positioned at same plane, acutangulate angle.Perhaps installing hole axis Z and working shaft axis Y also can acutangulate angle by antarafacial.Jackshaft 5 inserts installing holes 611, makes jackshaft axis X and installing hole axis Z conllinear, and the assembling of jackshaft 5, working shaft 61 is simple.Because working head 62 can rotate freely around the working shaft axis, the motion of working head 62 is around the revolution of jackshaft axis X with around the compound motion of the rotation of working shaft axis Y.This kind compound motion can be decomposed into along the axial swing of jackshaft 5 and be rotatablely moving of axis with jackshaft 5.Running into the resistance greater than predetermined size when working head 62 inserts soil, as greater than 1 newton's resistance the time, is that rotatablely moving of axis is suppressed with working shaft 61, and only takes place along the axial swing of jackshaft 5.The angle of swing is specially 2 times of angle of installing hole axis Z and working shaft axis Y.Preferably, the angle of installing hole axis Z or jackshaft axis X and working shaft axis Y be 5 spend to 45 the degree, the pendulum angle of working head 62 be 10 spend to 90 the degree.Spend between 45 degree 5, the scope of loosening the soil of loosenning tiller 100 increases obviously.The amplitude of loosening the soil of working head 62 can be regulated with pendulum angle.Special, the angle of installing hole axis Z and jackshaft axis X is 30 to spend between 45 degree, and working head 62 inserts soil easily, and has the bigger power of loosening the soil.
Under the situation of working method for swing of working head 62; Operating personnel's the bottom of s trouser leg or the weeds on the soil can not be entangled on the parts that rotatablely move of loosenning tiller 100 fully; Therefore; The use of this kind loosenning tiller 100 is as safe as a house, and need not shut down to remove and be wound into the weeds on the rotating moving part, and the efficient of loosening the soil is very high.And because working head 62 reciprocally swingings, the soil of working head 62 working regions can be from circumferentially not thrown away by centrifugal, thereby reduce the soil loss of loosening the soil a little and can not throw on one's body the operating personnel.After the operator was fixed on a position with working head, working head 62 swings were loosened the soil, and can realize point-to-point operation.
The operation principle of facing the manual mode of loosenning tiller 100 down elaborates.
Jackshaft axis X and working shaft axis Y can be positioned at same plane, acutangulate angle.Perhaps installing hole axis Z and working shaft axis Y also can acutangulate angle by antarafacial.Because working head 62 is not around the axial revolution of jackshaft 5, so working head 62 only has the rotation around working shaft axis Y.
The dynamical type loosenning tiller of transmission is that power directly drives the working head rotation.And when working head drives structure when rotation relatively, the driving force that working head receives can't be worked by soil resistance.Therefore traditional dynamical type loosenning tiller drives structure and working head are for being fixedly connected.Connect drives structure step by step and be essentially lever, driving force is positioned at the end away from fulcrum, and the reaction force of soil is positioned at the end near fulcrum.If when dynamical type changed manual type into, push-pull effort must overcome the SR of this drives structure.So push-pull effort is very big, even almost can not promote.The loosenning tiller 100 of this embodiment is provided with the working shaft 61 that is therefrom passed by jackshaft 5, and working head 62 is rotatably installed on the working shaft 61, and working shaft axis Y and jackshaft axis X acutangulate angle.When working power, working head 62 can reciprocally swinging; When manual, working head 62 rotates around working shaft axis Y.Realized the combination of dynamical type and manual type.
The loosenning tiller that this embodiment provides can be worked under manual mode, also can under electric model, work, and below introduces respectively.
Under manual mode, loosenning tiller 100 is manually actuated and loosens the soil under the situation that maintained switch 8 breaks off.The power drive system of loosenning tiller 100 is not worked.And because there is output shaft counter motion locking system power drive system inside, when attempting externally rotation work axle 61, output shaft counter motion locking system can be with this kind motion locking.Simultaneously and since working head 62 can be freely around working shaft 61 rotations, so switch 8 breaks off, when promoting the relative soil movement of loosenning tiller 100, working head 62 can rotation and working shaft 61 maintenances are static, loosenning tiller 100 only works as a traditional manual loosenning tiller.
Push the working head 62 of loosenning tiller 100 to soil;
Keep the switch 8 of loosenning tiller 100 to be in off-state;
On soil, promote loosenning tiller 100, working shaft 61 is static with respect to the housing 41 of loosenning tiller 100, and working head 62 loosens the soil with respect to working shaft axis Y rotation.
Under electric model, 8 conductings of loosenning tiller 100 maintained switch are used motor 42 power drive working shafts 61 to move with working head 62 and are loosened the soil.It should be noted that owing to frictional resistance between working head 62 and the working shaft 61 is less, can rotate freely relatively; When working head 62 receives soil resistance, be easy on direction of rotation that soil conservation is static relatively, and working shaft 61 drove at motor 42 and kept down rotating this moment; And has the acute angle angle between working shaft axis Y and the jackshaft axis X; Therefore, working shaft 61 drives working head 62 along jackshaft 5 axial wobbles, realizes loosening the soil.The reaction force direction of working head 62 swing this moment and jackshaft 5 are parallel and to act on the application of force direction of handle 2 vertical with the operator, so the vibration force direction is also vertical with operator's application of force direction.It is opposite answering the swaying direction of a plurality of working heads 62 simultaneously, and its vibration can be cancelled out each other.It is very little that the operator grips the vibration at place, operates comfortable.
Like this, when the housing 41 of loosenning tiller 100 is constant basically with respect to the soil position, realize that the original place is electronic to loosen the soil that its concrete operating procedure is following:
Push the working head 62 of loosenning tiller 100 to soil;
Keep the switch 8 of loosenning tiller 100 to be in conducting state;
Keep the housing 41 of loosenning tiller 100 constant basically with respect to the position of soil;
Working head 62 direction of rotation under soil resistance keeps static, in motor 42 driving lower edge jackshaft 5 axial wobbles.
When the housing of loosenning tiller 100 41 moves with respect to soil, realized advancing and electronic loosening the soil, its concrete operating procedure is following:
Push the working head 62 of loosenning tiller 100 to soil;
