Description

Technical Field

[0001] The utility model relates to the technical field of crop cutting, in particular to a device for crop cutting and processing. Background Art

[0002] The straw of crops is the general term for the stems, leaves and spikes of mature crops, usually the remaining part of crops after harvesting seeds. More than half of the products of crop photosynthesis are present in the straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a multi-purpose renewable biological resource. Straw is also a roughage, characterized by a high crude fiber content of 30%-40%, and contains lignin, etc. Although lignin cellulose cannot be used by pigs and chickens, it can be absorbed and used by ruminants such as cattle and sheep. After cutting and crushing, the straw can be made into various agricultural by-products for recycling. The existing straw crusher cuts and crushes the straw particles larger, and the machine is prone to jamming inside, affecting the crushing efficiency. Utility Model Content

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations:

[0018] A device for cutting and processing crops comprises a shell 1 and a cutting device 2. The shell 1 is cylindrical, and the cutting device 2 is arranged inside the shell 1.

[0019] The slitting device 2 includes a rotating shaft 21, both ends of the rotating shaft 21 are connected to bearings 22, the bearings 22 are connected to bearing seats 23, the bearing seats 23 are fixedly connected to the outer shell 1, a feed port 3 is provided on one side of the outer shell 1, a cutting mechanism 4 is provided on the rotating shaft 21 corresponding to the feed port 3, the cutting mechanism 4 includes two connecting plates 41, the two connecting plates 41 are fixedly connected to the rotating shaft 21, a plurality of cutting blades 42 are fixedly connected in a circular array between the two connecting plates 41, the cutting blade 42 is provided with a blade 43, and the cutting blade 42 is installed at an angle.

[0020] A shredding mechanism 5 is provided on the left side of the cutting mechanism 4. The shredding mechanism 5 includes a rotating roller 51 fixedly connected to the rotating shaft 21. A plurality of groups of shredding knives 52 are staggeredly arranged on the rotating roller 51. Each group of the shredding knives 52 includes two blades 53 arranged opposite to each other in the shape of a "one". A plurality of trapezoidal fixed blocks 54 are arranged in parallel in the shape of a "one" on the inner walls of the front and rear sides of the housing 1 corresponding to the shredding knives 52. A cutting groove 55 is formed between two adjacent fixed blocks 54. When the shredding knives 52 move to the position of the fixed block 54, they are placed in the cutting groove 55.

[0021] A plurality of baffle bars 6 are provided at the bottom of the housing 1 corresponding to the chopping knife 52. When the chopping knife 52 moves to a position relative to the baffle bars 6, the distance between the bottom of the chopping knife 52 and the top of the baffle bars 6 is 1-3 mm.

[0022] Furthermore, the cutting blade 42 is inclined at 5°-10°.

[0023] Furthermore, a discharge hopper 7 is provided at the leftmost end of the housing 1, and the discharge hopper 7 is arranged to be inclined downward.

[0024] Furthermore, the chopping knife 52 has a thickness of 5-12 mm.

[0025] When the crop cutting and processing device is in use, the crop straw is fed into the housing 1 from the feed port 3, and the external power device drives the rotating shaft 21 to rotate. As the rotating shaft 21 rotates, the cutting mechanism 4 rotates accordingly. As the cutting blade 42 rotates, the cutting blade 42 cuts the straw into segments, and the cut crops enter the chopping mechanism 5.

[0026] On the inner walls of the front and rear sides of the housing 1 corresponding to the chopping knife 52, a plurality of trapezoidal fixed blocks 54 are arranged in a "one" shape in parallel, and a cutting groove 55 is formed between two adjacent fixed blocks 54. A plurality of baffles 6 are provided at the bottom of the housing 1 corresponding to the chopping knife 52. When the chopping knife 52 moves between the cutting grooves 55 and when the distance between the chopping knife 52 and the baffles 6 is the smallest, a guillotine-like shape is formed, and the knife is not easily stuck during operation. Such a design enables the chopping knife 52 to chop the straw into relatively fine particles, and the chopped crop straw is sent out through the discharge hopper 9.

[0027] The chopping blade 52 is 5-12 mm thick and can exert greater pressure and shearing force on the crop straws, and is not easily damaged during use.

[0028] 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.
