Description
Technical field
The present invention is feeding, the threshing unit of crops thresher, belongs to agricultural mechanical field, is specifically related to a kind of rape thresher with feeding, separating mechanism.
Background technology
In China, it is main with manual work still that rape is gathered in the crops present stage, and mechanized harvest is at the early-stage.The separating mechanism of existing rape thresher all adopts the threshing principle of rice-wheat thresher; Both utilized the rigidity threshing tooth (bow tooth, fourth tooth etc.) on the high speed rotating threshing cylinder to impact threshing; This mechanism is not enough below being used in the rape threshing and existing: 1. rape seed the rigidity threshing tooth of high speed rotating impact be prone to down broken, cause the rape seed oil yield to reduce and fragmentation after rape seed also can be with tiny assorted surplus separated shedding, 2. since siliqua of oilseed rape disperse; The threshing tooth is rare; The not thorough phenomenon of threshing occurs, waste is serious, and 3. the threshing power consumption is big.
Simultaneously; The feeding mechanism that existing rape thresher is selected for use is the open type spout; Rape seed is outwards shed very serious under the impacting of high speed rotating threshing tooth; The threshing percent of loss is too big, and these are not enough and defective has only just seriously restricted the development of rape thresher toolization from this procedure of rape threshing.
Summary of the invention
The objective of the invention is to overcome deficiency and defective that prior art exists, propose that a kind of threshing power consumption is little, threshing thoroughly, do not have and shed, the very low a kind of rape thresher of threshing percentage of damage and percent of loss is with feeding, separating mechanism.
The technical scheme that realizes above-mentioned purpose is: a kind of rape thresher is with feeding, separating mechanism, and it comprises threshing bin, pencil elasticity threshing tooth, liner plate, quick threshing cylinder, threshing cylinder, straw cut off tooth, drum shaft, small pulley, flat belt, big belt wheel, vee-pulley, V belt, notch board and spout at a slow speed.Said quick grain cylinder is the rotatingcylindrical drum of a pair of forward and reverse rotation with a grain cylinder at a slow speed, and its speed ratio is 1: 0.5-0.7, and two cylinders all are installed in the threshing bin through drum shaft and bearing, and quick threshing cylinder is located at the top of threshing cylinder at a slow speed.Break away from outer surface of cylinder fast and be provided with number row pencil elasticity threshing tooth; And distribute along right-hand helix; Also be provided with number row pencil elasticity threshing tooth at a slow speed on the threshing cylinder outer surface; Its rotation direction is left-handed, is interval with straw simultaneously on this outer surface of cylinder on every row's pencil elasticity threshing tooth position and cuts off tooth, and not dress shape elasticity threshing tooth of position that straw cuts off tooth is housed.Said pencil elasticity threshing tooth is a 3-4 root spring steel wire, and about every highly equal 6cm, scatter in the end, and the tip slightly contacted when the threshing tooth on the fast threshing cylinder at a slow speed met.The drum shaft of threshing cylinder is provided with small pulley fast; The drum shaft of threshing cylinder is provided with big belt wheel and vee-pulley at a slow speed; Big small pulley is by the flat belt transfer motion power that intersects, and main frame power passes to the drum shaft of threshing cylinder at a slow speed through V belt, vee-pulley.Said threshing bin top is provided with the arc liner plate of sealing and adjustable clearance; The bottom is provided with the arc notch board of latticed and adjustable clearance; The bottom is the material mouth, and the front portion is provided with the tubaeform spout of a semiclosed and opening updip, and tubaeform spout cross section is a rectangle.
Effect of the present invention is: a kind of rape thresher of making according to such scheme is with feeding, separating mechanism; Adopt pencil elasticity threshing tooth, liner plate, notch board and threshing cylinder at a slow speed soon; Through currying, rub and elasticity impacting principle and makes siliqua of oilseed rape cracking; Adopt semiclosed updip spout to make the rape seed material resilience of outwards splashing at a high speed in the threshing bin, threshing performance is high when having guaranteed the rape threshing, nothing is shed, percentage of damage is low, percent of loss is low, power consumption is little.This mechanism structure is simple, be convenient to processing, practical.

Embodiment:
Below in conjunction with accompanying drawing the present invention is described further.
As depicted in figs. 1 and 2, the present invention is that a kind of rape thresher is with feeding, separating mechanism.It comprises threshing bin 1, pencil elasticity threshing tooth 2, liner plate 3, quick threshing cylinder 4, threshing cylinder 5, straw cut off tooth 6, drum shaft 7, notch board 13 and spout 15 at a slow speed.Fast threshing cylinder 4 and at a slow speed threshing cylinder 5 be the cylindrical roller of a pair of forward and reverse rotation; Be installed in the threshing bin 1 through bearing and drum shaft 7 respectively; Threshing cylinder 4 is provided with the pencil elasticity threshing tooth 2 and drum shaft 7 that number row distributes along right-hand helix fast, and drum shaft 7 is provided with small pulley 8.Threshing cylinder 5 is provided with the pencil elasticity threshing tooth 2 and drum shaft 7 that number row distributes along the left-hand screw line at a slow speed; Drum shaft 7 is provided with big belt pulley 10 and vee-pulley 11; Simultaneously be interval with straw on the position of the every row's pencil elasticity threshing tooth on the threshing cylinder 5 at a slow speed and cut off tooth 6, have straw to cut off the position uneasy dress shape elasticity threshing tooth 2 of tooth 6.The top of threshing bin 1 is provided with arc liner plate 3, and the bottom is provided with arc notch board 13, and the front portion is provided with spout 15, and the bottom is a material mouth 14.
Main frame power drives vee-pulley 11 rotations through V belt 12 during work; Big belt wheel 10 drives small pulleys 8 rotations through flat belt arranged in a crossed manner 9, realizes quick threshing cylinder 4 and the rotary speed of forward and reverse rotation and two cylinders of threshing cylinder 5 is poor at a slow speed.After rape straw is through spout 15 feeding, impact the back through pencil elasticity threshing tooth 2 elasticity and realize threshing for the first time, when being impacted the vegetable seed that splashes in the threshing bin 1 and outwards splashing,, can outwards not shed through spout 15 resiliences of semiclosed and opening updip.After rape straw gets between two cylinders; Because there is speed difference in two cylinders; The pencil elasticity threshing tooth 2 that the left and right sides rotation direction that distributing on two cylinders is different, and pencil elasticity threshing tooth 2 ends scatter, and slightly contact when meeting; So this stage can be accomplished threshing for the second time through currying effect, threshing for the second time is very abundant.The rape seed that is not broken away from for only a few is through pencil elasticity separating tooth 2 on the quick disengaging cylinder 4 and liner plate 3 and break away from rubbing between pencil elasticity threshing tooth 2 and the notch board 13 on the cylinder 5 at a slow speed and realize threshing for the third time.Rape seed is discharged from material mouth 14 through grid type notch board 13 backs, gets into the follow-up air draught type separating cleaning stage, and straw gets into the vibrations bolter and realizes later separation above grid type notch board 13.
