Abstract
The invention discloses a forward and reverse driving shifter, and relates to components of agricultural machinery. The forward and reverse driving shifter comprises a spindle of a motor, wherein a shaft sleeve is sleeved on the spindle of the motor and can rotate along with the spindle of the motor synchronously; a forward driving wheel is connected to one end of the shaft sleeve through a bearing; a reverse driving wheel is connected to the other end of the shaft sleeve through a bearing; a shifting block which can move in a reciprocating manner along the axial direction of the shaft sleeve is sleeved on the shaft sleeve between the forward driving wheel and the reverse driving wheel; projections are respectively arranged on a surface, which is opposite to the shifting block, of the forward driving wheel and a surface, which is opposite to the shifting block, of the reverse driving wheel; grooves which are matched with the projections are respectively formed in two sides of the shifting block; and a screw transmission mechanism is arranged between the shaft sleeve and the shifting block. When the driving wheel on one side is driven, the driving wheel on the other side is released from transmission fit and cannot idle reversely, abrasion is reduced, the noise is also reduced, the service life of the agricultural machinery is prolonged, and the forward and reverse driving shifter is quite convenient and practical.
Description
Technical field
The present invention relates to a kind of agricultural machinery parts, relate in particular to a kind of forward and reverse driving switching device shifter.
Background technology
Husk rice crushing combined machine is a kind of agriculture combined machine that can complete respectively husk rice and crushed work, and it can complete two kinds of different work by a kind of type.The conversion of the different operating modes of existing husk rice crushing combined machine bothers very much, the forward and reverse driving of its belt pulley realizes by corresponding ratchet mechanism, therefore when driving forward or backwards, the opposing party's ratchet does not depart from transmission and still does reverse idle running, caused that wearing and tearing are large and noise is large, machine easily damages, and service life is low.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of forward and reverse driving switching device shifter, when a side drive wheel is driven, the driving wheel of opposite side departs from transmission and coordinates, and can oppositely not dally, and has reduced wearing and tearing, reduce noise, extended machine service life, very convenient and practical.
Technical scheme of the present invention is: a kind of forward and reverse driving switching device shifter, comprise motor main shaft, on described motor main shaft, be socketed with axle sleeve, described axle sleeve can synchronously rotate with motor main shaft, forward drive wheel is connected in wherein one end of axle sleeve by bearing, reverse drive wheel is connected in the axle sleeve other end by bearing, forward drive wheel and reverse drive wheel surface are respectively arranged with reinforcement, on axle sleeve between forward drive wheel and reverse drive wheel, being socketed with can be along the axial reciprocating handoff block of axle sleeve, on forward drive wheel and reverse drive wheel and handoff block face in opposite directions, be respectively arranged with projection, handoff block both sides are respectively arranged with the groove coordinating with projection, between axle sleeve and handoff block, be provided with screw-drive mechanism.
As preferably, between the axle sleeve surface between forward drive wheel and reverse drive wheel and handoff block, be respectively arranged with the half groove type helical raceway that can cooperatively interact, in the half groove type helical raceway that axle sleeve coordinates with handoff block, be provided with ball.
As preferably, described axle sleeve two ends are fixedly connected on motor main shaft by nut respectively, between nut and axle sleeve, are provided with stay.
The invention has the beneficial effects as follows: the present invention drives forward drive wheel and reverse drive to take turns by the handoff block on axle sleeve, when motor main shaft rotates forward or backwards, synchronous rotation along with axle sleeve, the ball arranging in half groove type helical raceway makes handoff block move to direction close or that take turns away from forward drive, after contacting with forward drive wheel or reverse drive wheel, projection and groove fit, drive forward drive wheel or the synchronous rotation of reverse drive wheel, when the driving wheel of axle sleeve one side rotates, the driving wheel of handoff block and opposite side departs from transmission mated condition, can oppositely not dally, wearing and tearing have been reduced, reduced noise, extended machine service life, very convenient and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, motor main shaft; 2, axle sleeve; 3, reverse drive wheel; 4, forward drive wheel; 5, ball; 6, handoff block; 7, half groove type helical raceway; 8, bearing; 9, stay; 10, nut.
