The power device 1 includes an engine 101. The upper part of the engine 101 is connected to an oil tank 102. The output shaft 103 of the engine 102 is connected to a transmission wheel 104. The transmission wheel 104 is connected to a transmission wheel 2 106 through a conveyor belt 105.

[0023] The shredding device 3 includes an outer cover 301 and a rotating shaft 302. Both ends of the rotating shaft 302 are connected to bearings 303. The bearings 303 are connected to bearing seats 304. The bearing seats 304 are fixedly connected to the frame 2. One end of the rotating shaft 302 is fixedly connected to the transmission wheel 2 106. A feed port 4 is provided on one side of the outer cover 301. A cutting device 5 is provided on the rotating shaft 302 corresponding to the feed port 4. The cutting device 5 includes two connecting plates 51. The two connecting plates 51 are fixedly connected to the rotating shaft 302. A plurality of cutting blades 52 are fixedly connected in a circular array between the two connecting plates 51. The cutting blades 52 include a knife plate 53 and a blade 1 54. The cutting blades 52 are installed at an angle.

[0024] A pair of cutting knives 6 are provided on the left side of the cutting device 5, and the two cutting knives 6 are in the shape of a letter "I", and the blades 61 of the cutting knives 6 are arranged opposite to each other. The cutting knives 6 are fixedly connected to the knife seat by bolts, and the knife seat 62 is fixedly connected to the rotating shaft 302; a shredding mechanism 7 is provided on the left side of the cutting knife 6, and the shredding mechanism 7 includes a roller 71 fixedly connected to the rotating shaft 302, and a plurality of groups of shredding knives 72 are staggeredly arranged on the roller 71, and each group of shredding knives 72 includes two blades 73 arranged opposite to each other in the shape of a letter "I", and a plurality of trapezoidal fixed blocks 74 are arranged in parallel in the shape of a letter "I" on the inner walls of the front and rear sides of the outer cover 301 corresponding to the shredding knives 72, and a cutting groove 75 is formed between two adjacent fixed blocks 74, and when the shredding knives 72 move to the position of the fixed block 74, they are placed in the cutting groove 75.

[0025] A plurality of baffles 76 are provided at the bottom of the outer cover 301 corresponding to the cutting knife 6 and the chopping knife 72. When the chopping knife 72 moves to a position relative to the baffles 76, the distance between the bottom of the chopping knife 72 and the top of the baffles 76 is 1-3 mm.

[0026] A plurality of discharge plates 8 are provided in a circular array on the left side of the rotating roller 71 near the left side wall of the outer cover 301 , and a discharge bin 81 is formed between two adjacent discharge plates 8 . A discharge hopper 9 is provided on the outer cover 301 corresponding to the discharge plates 8 .

[0027] Furthermore, the cutting blade 52 is inclined at 5°-10°.

[0028] Furthermore, the discharge plate 8 is in the shape of a right-angled trapezoid.

[0029] Furthermore, the discharge hopper 9 is arranged to be inclined downward.

[0030] Furthermore, the chopping knife 72 has a thickness of 5-12 mm.

[0031] When the corn stalk crushing machine is in use, the stalk is fed into the outer cover 301 from the feed port 4, and the engine 101 drives the transmission wheel 1 104, the conveyor belt 105, the transmission wheel 2 106, and the rotating shaft 302 to rotate in sequence. As the rotating shaft 302 rotates, the cutting device 5 rotates accordingly. As the cutting blade 52 rotates, the cutting blade 52 cuts the stalk into segments. The cut stalk is cut into smaller segments as the cutting knife 6 rotates, which is convenient for subsequent chopping. The stalk cut into small segments enters the chopping mechanism 7.

[0032] On the inner walls of the front and rear sides of the outer cover 301 corresponding to the chopping knife 72, a plurality of trapezoidal fixed blocks 74 are arranged in a "one" shape in parallel, and a cutting groove 75 is formed between two adjacent fixed blocks 74. A plurality of baffles 76 are provided at the bottom of the outer cover 301 corresponding to the cutting knife 6 and the chopping knife 72. When the chopping knife 72 moves between the cutting grooves 75 and the cutting knife 6 and the chopping knife 72 move to the minimum distance from the baffles 76, a guillotine-like shape is formed. Such a design enables the cutting knife 6 and the chopping knife 72 to chop the straw into relatively fine particles, and the chopped straw is sent out from the discharge hopper 9 through the discharge bin 81.

[0033] The chopping blade 72 is 5-12 mm thick, can exert greater pressure and shear force on the straw, and is not easily damaged during use.

[0034] The specific implementation of the utility model is described in detail above, but it is only used as an example. The utility model is not limited to the specific implementation cases described above, and equivalent modifications to the utility model are also within the protection scope of the utility model.
