Description

TECHNICAL FIELD

[0001] The application relates to the field of agricultural machinery, in particular to a compound bionic digging shovel based on mole and mole cricket claw toe structures. BACKGROUND

[0002] Taking potatoes as an example, potato digging is an important process of potato harvesting, and the working performance of the digging shovel directly affects the potato harvesting effect. In order to effectively harvest potatoes, the digging shovel needs to have excellent soil breaking capacity and small digging resistance, and at the same time, the separation of potato and soil should be as thorough as possible and the damage to potatoes should be reduced. The existing potato harvester digging shovel is mainly a flat shovel, which is simple in form and structure. When digging potatoes, the phenomenon of clay sticking is serious, the soil resistance is large, the soil breaking and soil breaking capacity is poor, the damage to potatoes is high, and under complex ground conditions, the shovel has poor adaptability, low reliability and other problems, resulting in high energy consumption of the harvester. With the expansion of potato planting scale, the soil texture and planting agricultural conditions in potato producing areas are becoming more and more complex, and the traditional flat digging shovel is gradually difficult to adapt to high-intensity continuous work. Therefore, it is necessary to design a digging shovel with strong soil breaking capacity, good potato-soil separation effect, small digging resistance and low potato damage rate.

[0003] Some organs or structures of some animals or plants exhibit excellent working performance in the process of digging and cutting, which has certain similarity with the digging process of the digging shovel: for example, the claw toes of moles and other soil animals are shovel-shaped, which are very similar to digging shovels and still exhibit good working performance after long-term digging; the claw toes of mole crickets are similar to wedge-shaped structures, which can effectively alleviate the accumulation of soil at the tip of the claw toes and reduce the cutting resistance. The above structures provide a good design basis for the design of root crop digging shovels. The vibrating screen moves and screens the materials on the screen surface through the vibration generated by the vibrating motor, which exhibits excellent working performance in the process of screening materials. Harvesting machines have certain vibration in the working process. Through vibration, the soil particles attached to the surface of the digging shovel and the surface of the roots / tubers can be effectively separated, the soil accumulation of the digging shovel can be effectively alleviated, the cutting resistance can be reduced, and the soil attached to the surface of the digging shovel and the surface of the roots / tubers can be effectively reduced. The above method provides a good basis for the optimization of the structure and performance of the root crop digging shovel. Therefore, the application provides a compound bionic digging shovel based on mole and mole cricket claw toe structures to meet the needs. SUMMARY
