Abstract
The utility model discloses a rice and wheat thresher, break away from cylinder, drive in frame, frame break away from the pivot of cylinder and are located and break away from cylinder outlying screen cloth, still include to carry out the knocking device that strikes to the screen cloth, knocking device includes that axial direction parallel strikes the drive mechanism of the radial reciprocating motion of pole in order to strike the screen cloth in the pole that strikes that breaks away from the cylinder with the drive. Strikeing pole reciprocating motion and strikeing the screen cloth, the straw on the screen cloth breaks away from the screen cloth under vibratory action, and then avoids screen mesh blockage.
Description
Technical field
The utility model relates to agricultural mechanical field, particularly a kind of rice-wheat thresher.
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, and the straw that straw is particularly moist is easily bonded on screen cloth, and cause screen cloth to block, grain cannot normally spill from screen cloth, and straw also cannot be blown out frame by blower fan.
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, and straw can be avoided to block screen cloth.
Rice-wheat thresher of the present utility model; comprise the detachment roller in frame, frame, drive the rotating shaft of detachment roller and be positioned at the screen cloth of detachment roller periphery; also comprise the knocking device knocked screen cloth, described knocking device comprises the bar that knocks being axially parallel to detachment roller and knocks the reciprocating motion of bar radial direction with the transmission mechanism knocking screen cloth with driving.
Further, described transmission mechanism comprises crank and connecting rod, and described crank is placed in rotating shaft and rotates with it, and described connecting rod two ends are respectively with crank with to knock bar hinged.
Further, the quantity of described transmission mechanism is two covers, is symmetricly set in the two ends of rotating shaft respectively, is provided with swivel nut between the connecting rod of two sets of transmission mechanism, and described swivel nut two ends are connected with the bolt thread through two connecting rods respectively.
The beneficial effects of the utility model: rice-wheat thresher of the present utility model; comprise the detachment roller in frame, frame, drive the rotating shaft of detachment roller and be positioned at the screen cloth of detachment roller periphery; also comprise the knocking device knocked screen cloth, described knocking device comprises the bar that knocks being axially parallel to detachment roller and knocks the reciprocating motion of bar radial direction with the transmission mechanism knocking screen cloth with driving.Knock bar move back and forth and knock screen cloth, the straw on screen cloth departs from screen cloth under effect of vibration, and then avoids screen cloth to block.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model.
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; comprise the detachment roller 2 in frame 1, frame, drive the rotating shaft 3 of detachment roller and be positioned at the screen cloth 4 of detachment roller periphery; also comprise the knocking device knocked screen cloth 4, described knocking device comprises the bar 5 that knocks being axially parallel to detachment roller and knocks the reciprocating motion of bar radial direction with the transmission mechanism 6 knocking screen cloth with driving.Knock the outside that bar is positioned at screen cloth 4, under transmission mechanism effect, knock screen cloth 4 to detachment roller direction, under screen cloth 4 vibrates, the straw be bonded on screen cloth departs from screen cloth 4, thus avoids screen cloth blocking.
The transmission mechanism 6 knocking bar 5 can be cylinder isoline output mechanism, transmission mechanism 6 in the present embodiment comprises crank 61 and connecting rod 62, described crank 61 is placed in rotating shaft 3 and rotates with it, described connecting rod 62 two ends are respectively with crank 61 with to knock bar 5 hinged, frame has the elongated hole along knocking the setting of bar moving direction, knock bar through elongated hole, and reciprocating linear moves under elongated hole restriction.Crank 61, connecting rod 62 and knock bar 5 and define slider-crank mechanism, crank 61 rotates with rotating shaft 3, under connecting rod 62 acts on, be converted into the linear reciprocating motion knocking bar 5.
As the further improvement of technique scheme, the quantity of described transmission mechanism 6 is two covers, be symmetricly set in the two ends of rotating shaft 3 respectively, swivel nut 7 is provided with between the connecting rod 62 of two sets of transmission mechanism, described swivel nut 7 two ends are threaded with the bolt 8 through two connecting rods respectively, and swivel nut 7 is coupled together by the connecting rod 62 of nut 8 by both sides, improves the rigidity of two final drive gears, ensure that the synchronism of two connecting rods 62 simultaneously, and be threaded be convenient to change swivel nut 7.
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.
