Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of Double drum thresher, and two threshing cylinders drive rotation by a sets of transmission mechanism simultaneously, and device structure is simple, low cost of manufacture.
Double drum thresher of the present utility model, comprise frame and be positioned at that two horizontal parallel of frame arrange first, second threshing cylinder, described first, second threshing cylinder is driven by a sets of transmission mechanism and rotates in opposite directions, described transmission mechanism comprises by motor-driven drive sprocket, drive first respectively, first of second threshing cylinder rotation, second by movable sprocket, turn to sprocket wheel and chain, described first by movable sprocket and turn to sprocket wheel to lay respectively at second by the both sides of movable sprocket, described drive sprocket, first by movable sprocket with turn to sprocket wheel to be positioned at inside chain to engage with chain, described second to be positioned at outside chain by movable sprocket and to engage with chain.
Further, described in turn to sprocket wheel to install on plain bearing housing, described plain bearing housing is driven by transverse-moving mechanism and turns to sprocket wheel axial direction to move along horizontal vertical in frame.
Further, described transverse-moving mechanism comprises and is fixedly connected on screw rod on plain bearing housing, the swivel nut coordinated with screw flight and locating dowel, on described swivel nut, circumferential symmetry has the through waist-shaped hole of two radial directions, described locating dowel one end is fixedly connected in frame, the other end passes two waist-shaped holes, and the width of the diameter of locating dowel and waist-shaped hole is suitable.
The beneficial effects of the utility model: Double drum thresher of the present utility model, comprise frame and be positioned at that two horizontal parallel of frame arrange first, second threshing cylinder, described first, second threshing cylinder is driven by a sets of transmission mechanism and rotates in opposite directions, described transmission mechanism comprises by motor-driven drive sprocket, drive first respectively, first of second threshing cylinder rotation, second by movable sprocket, turn to sprocket wheel and chain, described first by movable sprocket and turn to sprocket wheel to lay respectively at second by the both sides of movable sprocket, described drive sprocket, first by movable sprocket with turn to sprocket wheel to be positioned at inside chain to engage with chain, described second to be positioned at outside chain by movable sprocket and to engage with chain.By chain drive, second is contrary by turning to of movable sprocket with first by movable sprocket, therefore achieves and drive the one the second threshing cylinders to rotate in opposite directions by a sets of transmission mechanism simultaneously, device structure is simple, low cost of manufacture.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is elevation of the present utility model;
Fig. 2 is A portion zoomed-in view in Fig. 1;
Fig. 3 is the vertical view (locally) of Fig. 2.
Embodiment
Below with reference to accompanying drawing, the utility model is described in detail, as shown in the figure: the Double drum thresher of the present embodiment, comprise frame 1 and be positioned at that two horizontal parallel of frame arrange first, second threshing cylinder 2, 3, described first, second threshing cylinder 2, 3 to be driven by a sets of transmission mechanism 4 and rotate in opposite directions, described transmission mechanism 4 comprises by motor-driven drive sprocket 41, drive first respectively, second threshing cylinder 2, first of 3 rotations, second by movable sprocket 42, 43, turn to sprocket wheel 44 and chain 45, described first by movable sprocket 42 with turn to sprocket wheel 44 to lay respectively at second by the both sides of movable sprocket 43, described drive sprocket 41, first by movable sprocket 42 with turn to sprocket wheel 44 to be positioned at inside chain 45 to engage with chain 45, described second to be positioned at outside chain 45 by movable sprocket 43 and to engage with chain 45.Motor drives drive sprocket to rotate, engage with chain because the first passive chain and second is laid respectively at chain both sides by movable sprocket, such chain just drives first to be rotated in opposite directions by movable sprocket 43 by movable sprocket 42 and second, therefore achieve and drive first, second threshing cylinder 2,3 to rotate in opposite directions by a sets of transmission mechanism simultaneously, device structure is simple, low cost of manufacture.
As the further improvement of technique scheme, the described sprocket wheel 44 that turns to is installed on plain bearing housing 5, described plain bearing housing 5 is driven by transverse-moving mechanism 6 and turns to sprocket wheel 44 axial direction to move along horizontal vertical in frame 1, plain bearing housing 5 drives and turns to sprocket wheel 44 to move horizontally, thus tensioning chain 45, avoid chain-loose.
