Description
Technical field
The utility model relates to a kind of thresher, relates in particular to a kind of assorted surplus rethresher that is applied on the united reaper.
Background technology
Generally all be to utilize rethresher on the united reaper with cereal kernel and assorted surplus disengaging, to reach to its shelling edible purpose, the rethresher that uses on the existing united reaper generally is that an impeller and washboard are set in spiral case, by impeller is fixedly mounted on the tailing auger shaft, make the rotation of tailing auger shaft impeller, in the impeller rotation, drive cereal and on washboard, produce the action that friction is rubbed, cereal kernel is shelled, by the socket joint mouth of tossing cereal kernel is dished out from the socket joint mouth of tossing together with the shell of taking off then, to reach the separation of cereal kernel.This rethresher is to produce the action of rubbing between the end of impeller and washboard, for near the cereal at impeller shaft position without any effect, and shelling weak effect, cereal stops up when the socket joint mouth of tossing is dished out when separating easily, and the spiral case inner body damages not easy-maintaining, improved cost.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, increases air output, prevent to stop up, and the effective assorted surplus rethresher of threshing.
For solving the problems of the technologies described above, the technical solution of the utility model is: assorted surplus rethresher, comprise spiral case, described spiral case inwall is provided with passive scratching plate, has groove on the described passive scratching plate, described active scratching plate and described passive scratching plate are suitable, described active scratching plate is provided with gib block, tailing auger shaft passes passive scratching plate and active scratching plate successively, the back side of described active scratching plate is fixed with spline housing and blade, thrust spring is sleeved on the described spline housing, the rear portion of described tailing auger shaft is connected with described active scratching plate spline, the curved surface of described spiral case is provided with the socket joint mouth of tossing, and the opening of described toss socket joint mouth and described spiral case connecting portion is greater than the opening at the described socket joint mouth outlet position of tossing.
Described tailing auger the tip of the axis is provided with end cap, is provided with thrust spring between described end cap and the described active scratching plate.
The curved surface of described spiral case is provided with service hatch, on the described service hatch loose-leaf is installed.
Described blade is near the length of described tailing auger shaft and the end face parallel with the described tailing auger axis length less than the other end parallel with described tailing auger axis.
Owing to adopted technique scheme, rotate by tailing auger shaft, drive is arranged on the active scratching plate rotation above it, initiatively scratching plate is under the effect of thrust spring, move to passive scratching plate, and produce the action of rubbing with passive scratching plate, make the cereal shelling, then under the drive of the blade that rotates, with seed after separating and the assorted surplus socket joint mouth of tossing of bringing into, dish out from the outlet position of the socket joint mouth of tossing, reaching purpose, increased the area of rubbing cereal by active scratching plate and passive scratching plate to cereal shelling, increased the dynamics of rubbing by thrust spring to cereal, make shelling more thorough, the opening by the socket joint mouth connecting portion of tossing can increase air output greater than the opening at the described socket joint mouth outlet position of tossing, prevent seed and assorted surplus obstruction, the change of blade shape can reduce cost, and the utility model is simple in structure, and it is effective to shell.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in the figure, assorted surplus rethresher, comprise spiral case 3, described spiral case 3 inwalls are provided with passive scratching plate 7, has groove on the described passive scratching plate 7, described active scratching plate 9 and described passive scratching plate 7 are suitable, described active scratching plate 9 is provided with gib block 8, tailing auger shaft 1 passes passive scratching plate 7 and active scratching plate 9 successively, the back side of described active scratching plate 9 is fixed with spline housing 5 and blade 10, thrust spring 6 is sleeved on the described spline housing 5, the rear portion of described tailing auger shaft 1 is connected with described active scratching plate 9 splines, and the curved surface of described spiral case 3 is provided with the socket joint mouth 4 of tossing, and the opening of described toss socket joint mouth 4 and described spiral case 3 connecting portions is greater than the opening at the described socket joint mouth 4 outlet positions of tossing, can increase air output, prevent that blade from making cereal and assorted surplus obstruction in spiral case 3 in rotary course.
The end of described tailing auger shaft 1 is provided with end cap, is provided with thrust spring 6 between described end cap and the described active scratching plate 9, and thrust spring 6 can make active scratching plate 9 move to passive scratching plate 7 on tailing auger shaft 1.
The front end of described spiral case 3 is provided with tailing auger shaft housing 2.
The curved surface of described spiral case 3 is provided with service hatch, and loose-leaf 11 is installed on the described service hatch, during damage of components, is convenient to maintenance in the spiral case 3.
Described blade 10 can reduce cost by the shape that changes blade 10 near the length of described tailing auger shafts 1 and the end face parallel with the described tailing auger shaft 1 axis length less than the other end parallel with described tailing auger shaft 1 axis.
Described gib block 8 has certain radian, can make cereal enter the gap of rubbing of active scratching plate 9 and passive scratching plate 7 by gib block 8.
In use, tailing auger shaft 1 rotation, cereal is transported to the spiral case 3 from tailing auger shaft housing 2, the rear end of described tailing auger shaft 1 is a splined shaft, tailing auger shaft 1 rotation drives initiatively scratching plate 9 rotations, initiatively scratching plate 9 can move axially on tailing auger shaft 1, blade 10 is rotation thereupon also, because the effect of thrust spring 6, making initiatively, scratching plate 9 moves to the direction of passive scratching plate 7, make the groove that is provided with on gib block 8 that cereal is provided with on by active scratching plate 9 under its effect and the passive scratching plate 7 enter initiatively rubbing in the gap of scratching plate 9 and passive scratching plate 7, passive relatively scratching plate 7 rotations of scratching plate 9 simultaneously initiatively and produce and rub action, with cereal shelling, cereal kernel and assorted surplusly under the effect of blade 10, dish out then by the socket joint mouth 4 of tossing.
