Flail knife in described multiple row flail knife on arbitrary row is by integrated flail knife and combined type flail knife composition, and integrated flail knife and combined type flail knife interval are arranged.
The first belt pulley for being connected with the power take-off power of traction agricultural machinery is equipped with in described power transmission shaft one end, the power transmission shaft other end is equipped with uses the second belt pulley, the 3rd belt pulley cutter shaft is equipped with, second belt pulley is connected by belt with the 3rd belt pulley, is provided with and can makes the second belt pulley and the clutch that power transmission shaft power engages or power disconnects in the second belt pulley.
The both sides, rear portion of described frame are respectively connected with roller seat, and roller seat is rotatably connected to pack roller.
The front bottom of described frame is connected with catch axle, catch axle is coated with the catch that multi-disc can swing around it.
Occupation mode of the present utility model is as follows: be connected with tractor by hitch frame by straw cutting apparatus, first belt pulley is connected with the driving pulley in tractor motive power output shaft by belt, operation can be carried out by tractor-drawn after connection, straw cutting apparatus is with in tractor moving process, its cutter shaft rapidly rotates, corn stubble just can shred by the flail knife on cutter shaft, the corn stubble of chopping does not only affect cultivates, but also can organic manure be formed after rotting, thus the organic matter added in soil, very favourable to the growth of crops.
The utility model structure is simple, and its uses not only can bring reduction labour intensity, the beneficial effect of raising corn stubble elimination efficiency, and indirect belt can also improve the beneficial effect of soil organic matter content.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the syndeton schematic diagram of flail knife and cutter shaft.
Embodiment
Straw cutting apparatus as depicted in figs. 1 and 2, comprises frame 1, and described frame 1 is the bell-type frame of the bottom opening be made up of arc roof and end walls.The front top of frame 1 is provided with the hitch frame 7 for being connected with traction agricultural machinery (as tractor), frame 1 end walls is rotatably connected to cutter shaft 2, cutter shaft 2 is connected with multiple tool rest 4, each tool rest 4 is all hinged with flail knife, the power transmission shaft 3 for being connected with the power take-off power of traction agricultural machinery is equipped with at the top of frame 1, the first belt pulley 11 for being connected with the power take-off power of traction agricultural machinery is equipped with in power transmission shaft 3 one end, power transmission shaft 3 other end is equipped with the second belt pulley 12, the 3rd belt pulley 13 cutter shaft 2 is equipped with, second belt pulley 12 is connected by belt with the 3rd belt pulley 13, be provided with in second belt pulley 12 and can make the second belt pulley 12 and the clutch 14 that power transmission shaft 3 power engages or power disconnects.The front bottom of described frame 1 is connected with catch axle 8, catch axle 8 is coated with the catch 9 that multi-disc can swing around it, during operation, soil block or root stubble fragment can take up by the flail knife of high-speed rotation and dish out in bottom before frame 1, thus wound operator, and the effect of catch 9 is just to prevent soil block or root stubble fragment bottom before frame 1 from flying out, wound in order to avoid cause.
