Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a bionic kneading corn threshing and crushing all-in-one machine. Background Art

[0002] Corn, a staple crop in hilly and mountainous agricultural production, faces numerous challenges in its processing due to the complex environment. Due to the predominantly terraced and sloping terrain, confined working space, and inconvenient transportation, traditional corn processing exhibits a significant functional fragmentation. Processes such as peeling, threshing, and crushing rely on multiple independent machines for step-by-step completion. This decentralized operation forces farmers to repeatedly transport materials between the fields and drying yards, consuming significant manpower and resources, increasing equipment purchase and maintenance costs. Furthermore, the inconvenience of mountainous transportation creates material loss and safety risks, severely limiting production efficiency and exacerbating production pressures in rural areas facing labor shortages.

[0003] At present, for small-scale planting and family production scenarios, the widely used small corn thresher is usually composed of a grid, concave plate and threshing shaft roller welded with round steel. The threshing shaft roller is mostly welded with steel bars or arc-shaped tooth plates. Its working principle is to use the low-speed rotation of the threshing shaft roller to make the corn ears collide and squeeze with the steel bars, arc-shaped plates, grids and concave plates in the threshing chamber, thereby realizing the separation of corn kernels and cobs.

[0004] The contact between the threshing parts of the existing small thresher and the corn ears is rigid collision or extrusion, which belongs to the hard contact mode. This contact mode can easily cause some corn kernels to be broken or squeezed. If used for sowing next year, it will significantly reduce the germination rate of seeds, which is not conducive to corn seed retention and has an adverse impact on agricultural reproduction. Therefore, in response to the above situation, a bionic kneading corn threshing and crushing machine is proposed. Summary of the Invention

[0065] In the above embodiment, the outer shell 2 is provided with through holes for the flexible threshing shaft roller 40, the crushing shaft 54 ​​and the rotating shaft 10 to pass through.

[0066] When using the threshing and crushing machine: S1. Preparation stage: Check the connection of each component: confirm that the flexible threshing shaft roller 40 and the crushing shaft 54 ​​rotate flexibly (without jamming), the movable screen 52 is adjusted smoothly, and the belt tension is appropriate.

[0067] Adjust the crushing particle size: Turn the knob 530 as needed to drive the movable screen 52 to slide along the guide rod 503 through the screw 53 so that the gap with the fixed screen 51 reaches the target value.

[0068] S2, threshing process: Feeding: Corn (with cobs) enters the threshing chamber 20 from the first feed port 22 and falls onto the arc-shaped grid plate 43.

[0069] Kneading threshing: Turn on the power of the driving motor 6 and turn on its switch. The flexible threshing shaft roller 40 is driven to rotate clockwise through the third pulley 60 → belt → first pulley 400. The spiral threshing strips 41 on the shaft roller push the corn to move axially, and at the same time form a "squeeze-release" cycle with the steps 420 of the stepped baffle 42. The corn first enters the first step (20mm deep), where the gap between the threshing bar and the trough wall is larger (25mm), which initially separates the loose kernels. As the spiral pushes into the second step (depth 15mm), the gap narrows (20mm), and the flexible threshing shaft roller 40 slightly deforms to wrap the corn, and the kernels are separated from the core through the elastic kneading force of the polyurethane (mimicking the kneading action of human hands).

[0070] Grain separation: The fallen grains fall through the slits (8mm) of the arc-shaped grid plate 43 onto the V-shaped discharge plate 7 below, slide out along the inclined surface for collection, and the grains that are not completely fallen off re-enter the kneading area with the rotation of the shaft roller until they are separated.

[0071] S3. Corncob crushing process Core conveying: The threshed corn cobs are continuously pushed by the spiral threshing bar 41 and slide into the feed port 500 of the crushing bin 50 through the guide plate 8 (inclined at 30 degrees). If the corn cobs need to be crushed separately, the shifting block 12 is rotated to make the limiting plate 11 leave the bent plate of the second feed port 23, opening the feed channel so that the corn cobs can be directly fed from the second feed port 23.

[0072] Cutting and crushing: The first pulley 400 drives the second pulley 56 through the belt, causing the crushing shaft 54 ​​to rotate at high speed. The spiral blade 55 on the shaft cuts the corn cob. At the same time, the fixed screen 51 and the movable screen 52 form an annular crushing chamber. Under the centrifugal force of the blade 55, the corn cob sticks to the screen and is continuously cut into particles smaller than the screen gap. Then, it is discharged through the discharge port 501.
