Abstract
The utility model discloses an automatic play grass device of rice and wheat thresher, including the blown down tank that is located the straw export, still including the spout that is located the horizontal both ends of blown down tank, install rolling gyro wheel in the spout on the blown down tank, the blown down tank is by drive mechanism drive along its vertical reciprocating motion. Because the screen cloth can reciprocating motion to can exert certain external mechanical force to the straw on the screen cloth, be convenient for shift out the straw from the screen cloth, the while can not produce the raise dust.
Description
Technical field
The utility model relates to agricultural mechanical field, and particularly a kind of rice-wheat thresher goes out careless device automatically.
Background technology
Rice-wheat thresher cleans the compositions such as parts, seed output block, electromotor primarily of frame, screen cloth, threshing cylinder, blower fan.During rice-wheat thresher work; by artificial hand-held rice handle; threshing cylinder spike of rice being fed High Rotation Speed carries out threshing; grain spills from the screen cloth below threshing cylinder; enter blower fan inclined ramp to glide; blower fan air blast is up through blower fan inclined ramp, and air blast flow velocity just can blow out through blower fan the impurity such as lightweight straw from screen cloth, and grain falls from screen cloth and leaves thresher from grain blow tank simultaneously.Problems existing is, straw relies on the wind-force of blower fan to shift out from screen cloth, the external force that straw is subject to is less, it is low that straw shifts out efficiency, easy blocking blow tank, affects machine and normally produces, if will shift out straw fast, needs larger wind-force, larger airborne dust can be produced so again, affect ambient air quality.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of rice-wheat thresher automatically to go out careless device, can shift out straw fast, can not produce airborne dust simultaneously.
Rice-wheat thresher of the present utility model goes out careless device automatically; comprise the blow tank being positioned at straw outlet; also comprise the chute being positioned at blow tank transverse ends, described blow tank is provided with the roller rolled in chute, described blow tank is driven by transmission mechanism and longitudinally moves back and forth along it.
Further, the pulley that described transmission mechanism comprises cam, connecting rod, pulley base and is arranged on pulley base, described cam is placed on eccentric rotary in rotating shaft, the side face of described cam circumferentially has T-slot, described pulley base is positioned at the sipes of T-slot and the width of pulley base is greater than the width of the sipes of T-slot, described connecting rod one end is connected with pulley base by the narrow groove of T-slot, and the connecting rod other end is connected with blow tank, and described pulley rolls on the bottom land of the sipes of T-slot.
The beneficial effects of the utility model: rice-wheat thresher of the present utility model goes out careless device automatically; comprise the blow tank being positioned at straw outlet; also comprise the chute being positioned at blow tank transverse ends; described blow tank is provided with the roller rolled in chute, described blow tank is driven by transmission mechanism and longitudinally moves back and forth along it.Because screen cloth can move back and forth, thus certain mechanical external force can be applied to the straw on screen cloth, be convenient to straw to shift out from screen cloth, can not airborne dust be produced simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is schematic front view of the present utility model;
Fig. 2 is schematic top plan view of the present utility model;
Fig. 3 is A portion zoomed-in view in Fig. 2.
Embodiment
Below with reference to accompanying drawing, the utility model is described in detail; as shown in the figure: the rice-wheat thresher of the present embodiment goes out careless device automatically; comprise the blow tank 1 being positioned at straw outlet; also comprise the chute 2 being positioned at blow tank 1 transverse ends; described blow tank 1 is provided with the roller 3 rolled in chute 2, described blow tank 1 is driven by transmission mechanism 4 and longitudinally moves back and forth along it.After grain is separated in rice-wheat thresher with straw; straw is blowed to straw by blower fan and exports and fall on blow tank 1; the bottom surface of blow tank 1 is downward-sloping along discharging direction; blow tank 1 moves back and forth under transmission mechanism 4 drives; thus the straw in blow tank 1 is advanced along bottom surface vibrating type; and leave blow tank 1, accelerate the speed that straw leaves from thresher.
As the further improvement of technique scheme, described transmission mechanism 4 comprises cam 41, connecting rod 42, pulley base 43 and the pulley 44 be arranged on pulley base, described cam 41 is placed on eccentric rotary in rotating shaft 5, the side face of described cam 41 circumferentially has T-slot 45, described pulley base 43 is positioned at the sipes 451 of T-slot 45 and the width of pulley base 43 is greater than the width of the sipes of T-slot, described connecting rod 42 one end is connected with pulley base 43 by the narrow groove 452 of T-slot 45, connecting rod 42 other end is connected with blow tank 1, described pulley 44 rolls on the bottom land of the sipes 451 of T-slot 45.Connecting rod 42 is horizontally disposed with, when pulley 44 increases with the radius of gyration of cam 41 contact point, cam 41 promotes connecting rod 42 and blow tank 1 is moved to straw direction of advance, when pulley 44 reduces with the radius of gyration of cam 41 contact point, width due to pulley base 43 is greater than the width of the sipes of T-slot, therefore T-slot can drive pulley base 43, connecting rod and blow tank 1 to move to the opposite direction of straw discharge direction, thus achieves moving back and forth of blow tank 1.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
