Abstract
The utility model provides a cultivation cutter driving mechanism of a rotary cultivator, and belongs to the technical field of agricultural machinery. The cultivation cutter driving mechanism solves problems that rotation of an existing cultivation cutter of a rotary cultivator cannot be controlled when the rotary cultivator reverses or turns a corner, and the like. The cultivation cutter driving mechanism of the rotary cultivator is arranged between a power mechanism of the rotary cultivator and a rotary cultivation shaft, and comprises a transmission shaft, a worm gear and a worm. The transmission shaft is connected with the power mechanism, the worm gear is coaxially and fixedly connected onto the rotary cultivation shaft and is meshed with the worm, a one-way clutch is further arranged between the transmission shaft and the worm, the worm is fixedly connected with an inner ring of the one-way clutch, the transmission shaft is fixedly connected with an outer ring of the one-way clutch, and the worm, the one-way clutch and the transmission shaft are coaxial. Compared with the traditional cultivation cutter driving mechanism of a rotary cultivator, the cultivation cutter driving mechanism of the rotary cultivator has the advantages that the problem of reversion of a rotary cultivation shaft when a small rotary cultivator retreats is solved owing to the additional one-way clutch, and the cultivation cutter driving mechanism is simple in structure and low in cost.
Description
Technical field
The utility model belongs to the farm machinery technical field, relates to a kind of rotovator, particularly a kind of cultivated cutter driving mechanism of rotovator.
Background technology
Along with the development of science and technology, many peasants have replaced originally traditional labor type with sophisticated equipment when work, and to improve better working efficiency, the horizontal shaft type rotovator now also becomes the only selection of vast farmers cultivated land aspect farming.Although yet common horizontal shaft type rotovator has improved the efficient of ploughing, and is but still not fully up to expectations on some problems, such as the driving control of ploughing cutter shaft.Traditional horizontal shaft type rotavator plowing knife shaft is connected with the mode of engine shaft with worm and gear, is turning the control that can not get aspect stopping, and therefore ploughs the cutter forward when machine moves ahead, and ploughs cutter when machine falls back and reverses, and hurts easily operating personnel's pin.
Although some large-scale rotovator has added an engine for it again in order to control the rotor axle, with a driven by engine wheel shaft, plough cutter shaft with another driven by engine, plough turning to of cutter shaft although can control like this, but required cost is too high, is not suitable for the popularization of Miniature rotary cultivator for agriculture use.Therefore plough cutter and when rotovator advances, keep rotation, keep stopping this situation when falling back and turning and also have very large room for improvement.
Summary of the invention
The purpose of this utility model is to control existing the problems referred to above for existing horizontal shaft type rotary tillage tractor-ploughing cutter, and ploughs cutter work when having proposed a kind of rotovator and advancing, and ploughs the motionless cultivated cutter driving mechanism of cutter when machine retreats.
The purpose of this utility model can realize by following technical proposal: a kind of cultivated cutter driving mechanism of rotovator, be arranged between the actuating unit and rotary tillage shaft of rotovator, comprise power transmission shaft, worm gear and worm screw, power transmission shaft is connected with actuating unit, worm gear is coaxial to be connected on the rotary tillage shaft, worm gear and worm engaging, it is characterized in that, also be provided with an one-way clutch between described power transmission shaft and the worm screw, the inner ring of worm screw and one-way clutch is connected, the outer ring of power transmission shaft and one-way clutch is connected, worm screw, one-way clutch and power transmission shaft three concentric.
During the power transmission shaft forward, the one-way clutch adhesive is by the transmission drive rotary tillage shaft rotation of worm gear, worm screw, the cultivated cutter rotary operation on the rotary tillage shaft.During the power transmission shaft counter-rotating, the inner ring of one-way clutch separates with the outer ring, and rotary tillage shaft is failure to actuate.
In the cultivated cutter driving mechanism of above-mentioned rotovator, be connected by worm gear, worm-drive equally between the wheel shaft of described rotovator and the power transmission shaft.So, wheel shaft and rotary tillage shaft can share an actuating unit, and when rotovator advanced, wheel shaft and rotary tillage shaft can rotate synchronously.
Compare with the cultivated cutter driving mechanism of traditional rotovator, the problem that rotary tillage shaft reversed when the utility model had solved the small-size rotary tiller regression by the mode of setting up one-way clutch, simple in structure, cost is lower.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Among the figure, 1, one-way clutch; 2, power transmission shaft; 3, worm gear; 4, rotary tillage shaft; 5, wheel shaft; 6, sleeve pipe; 7, worm screw.
Embodiment
As shown in Figure 1, the cultivated cutter driving mechanism of this rotovator is arranged between the actuating unit and rotary tillage shaft 4 of rotovator, it comprises power transmission shaft 2, worm gear 3 and worm screw 7, one end of power transmission shaft 2 is connected with actuating unit, the other end passes a sleeve pipe 6 and is connected by an one-way clutch 1 afterwards with between the worm screw 7, worm screw 7 is connected with the inner ring of one-way clutch 1, and power transmission shaft 2 is connected worm screw 7, one-way clutch 1 and power transmission shaft 2 three's concentrics with the outer ring of one-way clutch 1.Worm gear 3 coaxial being connected on the rotary tillage shaft 4, worm gear 3 and worm screw 7 engagements.
The wheel shaft 5 of rotovator shares an actuating unit with rotary tillage shaft 4, and in the present embodiment, wheel shaft 5 also is connected with power transmission shaft 2 by transmission mechanism, and wheel shaft 5 is parallel with rotary tillage shaft 4.
When rotovator moved ahead farming, actuating unit drove power transmission shaft 2 forwards, and one-way clutch 1 adhesive makes power transmission shaft 2 and worm screw 7 form an interlock body, and power transmission shaft 2 drives wheel shaft 5 and rotary tillage shaft 4 rotating in same directions, and rotovator advances, and rotary tillage shaft 4 drives ploughs the cutter farming.During power transmission shaft 2 counter-rotating, the inner ring of one-way clutch 1 separates with the outer ring, and rotary tillage shaft 4 is failure to actuate, and power transmission shaft 2 drives wheel shaft 5 counter-rotatings and falls back.
Claims (2)
1. the cultivated cutter driving mechanism of a rotovator, be arranged between the actuating unit and rotary tillage shaft (4) of rotovator, comprise power transmission shaft (2), worm gear (3) and worm screw (7), power transmission shaft (2) is connected with actuating unit, worm gear (3) is coaxial to be connected on the rotary tillage shaft (4), worm gear (3) and worm screw (7) engagement, it is characterized in that, also be provided with an one-way clutch (1) between described power transmission shaft (2) and the worm screw (7), worm screw (7) is connected with the inner ring of one-way clutch (1), power transmission shaft (2) is connected worm screw (7) with the outer ring of one-way clutch (1), one-way clutch (1) and power transmission shaft (2) three's concentric.
