Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is that the B of Fig. 1 is to view.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of rice-wheat thresher comprises frame 1, is provided with threshing bin 2 on the frame 1, is provided with thrashing cylinder 3 in the threshing bin 2, and thrashing cylinder 3 is installed on the drum shaft 4, and drum shaft 4 is bearing on the frame 1 by bearing 14.
The place ahead of thrashing cylinder 3 and below are provided with front thrashing screen 5, and frame 1 is provided with threshing bin tailgate 6 and rear thrashing screen 7 at the rear of thrashing cylinder 2.Rear thrashing screen 7 is arranged on the below of threshing bin tailgate 6.
Threshing bin 2 is provided with the first rotating shaft 8, the first rotating shafts 8 in the front side, top of front thrashing screen 5 bottom is provided with two vibrating arms 9 vertically, and the bottom of each vibrating arm 9 is provided with pats piece 10.
One end face of thrashing cylinder 3 is concordant with the side plate outer face of threshing bin 2, and relative drum shaft 4 eccentric settings have shifting block 25 on the flush face of thrashing cylinder 3.
Flush face is provided with casing 12 in the outer ring of drum shaft 4.One end of the first rotating shaft 8 and first connecting rod 11 welding, the other end of first connecting rod 11 is by being placed on the casing 12.First connecting rod 11 is provided with cushion block 13 directly over casing 12.
Being provided be staggered the first parallel adjustment tank 61 and the second adjustment tank 62, the first adjustment tanks 61 and the second adjustment tank 62 of height on the vertical panel of threshing bin tailgate 6 is interconnected on top.The back segment of adjusting lever 16 is arranged in the first adjustment tank 61 or the second adjustment tank 62.The first adjustment tank 61 and the second adjustment tank 62 make adjusting lever 16 can be in two stations, and limit adjusting lever 16 at the limit of sports record of left and right directions, thereby prevent that adjusting lever 16 from conflicting with shifting block 25 occurrence positions.
Be provided with spring 17 between adjusting lever 16 and the frame 1.
The bottom of adjustment ring 15 is welded with second connecting rod 18, second connecting rod 18 right and left extend upwardly to shifting block 25 below.Second connecting rod 18 and the second rotating shaft 19 welding, the second rotating shaft 19 is arranged on the frame 1.The bottom of the second rotating shaft 19 left and right sides is welded with the first hinged block 20, the front lower place of rear thrashing screen 7 left and right sides be welded with the second hinged block 21, the first hinged blocks 20 and the second hinged block 21 hinged.
Because second connecting rod 18 and the second rotating shaft 19 welding further define adjusting lever 16 at the limit of sports record of left and right directions, thereby prevent that adjusting lever 16 from conflicting with shifting block 25 occurrence positions.
The top of the second rotating shaft 19 left and right sides is welded with cramp bar 22, and the rear end of support bar 22 is provided with mounting groove 23, and the rear end of rear thrashing screen 7 left and right sides is provided with mount pin 24, and mount pin 24 is arranged in the mounting groove 23.The length of mounting groove 23 is slightly larger than the stroke that seesaws of rear thrashing screen 7.
During thresher work, drum shaft 4 drives thrashing cylinder 3 and rotates under the effect of motor (not shown), thereby realizes the threshing to paddy rice or wheat.Simultaneously, shifting block 25 is made circular motion, and adjusting lever 16 is in position shown in Figure 3 in adjustment tank, and at this moment, the leading portion of adjusting lever and first connecting rod 11 are in released state all the time.Shifting block 25 moves upward and will the rear end of first connecting rod 11 be moved upward, thereby the first rotating shaft 8 is rotated, and then makes vibrating arm 9 drive the front thrashing screen 5 of beating piece 10 beatings, and the weeds that are attached on the front thrashing screen 5 are come off.When weeds are less on the current thrashing screen 5, can make adjusting lever leave the first adjustment tank 61 shown in Figure 3, enter in the second adjustment tank 62, therefore the leading portion of adjusting lever will the front upper motion take adjustment ring 15 as fulcrum, thereby lift first connecting rod 11, make shifting block 8 can not touch first connecting rod 11, therefore suspend and pat weeds.
On the other hand, shifting block 25 moves downward and will the front end of second connecting rod 18 be moved downward take adjustment ring 15 as fulcrum, thereby makes the rear end of second connecting rod 18 drive the second rotating shaft 19 rotations.The second rotating shaft 19 move through the first hinged block 20 and the second hinged block 21 is delivered on the rear thrashing screen 7, rear thrashing screen 7 relative gripper shoes 22 are seesawed, thereby straw or wheat straw on the rear thrashing screen 7 are travelled forward automatically, leave thresher.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all in the art technical staff comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
