The invention provides a multi-stage vibration sweet potato digging and conveying device which comprises a machine frame and further comprises a walking mechanism, a driving system assembly, a conveying mechanism, a digging mechanism, a vibration mechanism and a depth limiting mechanism, the walking mechanism is arranged at the bottom end of the machine frame, and the driving system assembly is arranged at the upper end of the machine frame; the conveying mechanism is erected at the upper end of the rack and located above the driving system assembly, the excavating mechanism is arranged at the front end of the conveying mechanism, the depth limiting mechanism is arranged at the front end of the conveying mechanism and located above the excavating mechanism, and the vibrating mechanisms are arranged in the middle of the conveying mechanism. The problems that the amount of labor used for sweet potato harvesting is large and the labor intensity is high at present are solved, and meanwhile the problems that sweet potato and soil separation is not clear, efficiency is low, digging resistance is large, and harvesting loss is large existing in sweet potato mechanical harvesting at present are solved.

The invention relates to the technical field of potato combine harvesters, in particular to a potato combine harvester sorting machine based on an image technology. The machine body comprises an excavating and conveying part, a transferring part and a sorting part which are arranged at intervals from front to back; the machine body is used for moving at ridge soil to be excavated and harvested; the digging and conveying part comprises a digging part and a conveying part; the digging part is positioned at the front part of the machine body and is used for digging out potato crops in soil; the conveying part is used for carrying out image recognition on the potatoes in the conveying process so as to carry out vibration soil cleaning at the self-adaptive frequency in the conveying process and obtain the potatoes subjected to soil cleaning; the transferring part is used for transferring the potatoes subjected to soil cleaning to a sorting part located at the rear part of the machine body; and the sorting part is used for automatically sorting the received tuber crops. According to the harvesting and sorting machine, vibration soil cleaning can be conducted on potatoes in a self-adaptive mode through image recognition, so that the energy consumption is reduced, meanwhile, the soil cleaning efficiency is ensured, and the harvesting and sorting machine is suitable for different soil planting environments.

The present invention provides a potato seedling cutting, harvesting and collecting integrated machine, which is used to solve the problems of incomplete potato-soil separation, easy potato damage and leakage, and separation of seedling cutting and harvesting in the prior art. The machine comprises: a walking collection device, a seedling cutting device, a digging device and a conveying and separating device. The walking collection device comprises a frame, a lifting and collecting mechanism arranged at the rear end of the mechanism; the seedling cutting device is arranged in front of the walking collection device; the digging device is located below the seedling cutting device; the conveying and separating device comprises two first support arms symmetrically installed on the frame and inclined at an angle to the ground, two second support arms symmetrically installed on the frame and arranged horizontally, a rotating conveying module for conveying a potato-soil mixture, and an ultrasonic potato-soil separation mechanism, wherein one end of the first support arm is fixedly connected to one end of the second support arm. The machine can not only complete the potato-soil cutting, harvesting and collecting in one body, thereby improving the harvesting efficiency, but also realize the thorough separation of potato and soil and solve the problems of potato damage and leakage.

The invention relates to agricultural machinery, in particular to a seed guiding and ditching mechanism. A gap exists between the two seed guide plates, the outlet end of the seed guide pipe is located between the two seed guide plates, the inlet end of the seed guide pipe is located in front of the outlet end of the seed guide pipe, the seed guide pipe is in a cycloid shape, the upper end of the seed guide pipe is connected with an air inlet pipe, and flowing gas is filled into the seed guide pipe through the air inlet pipe. The furrowing, seed guiding and soil covering are integrated, a proper seed guiding track and a proper furrow shape are formed, it is guaranteed that seeds fall at zero speed, bounce is prevented, and the uniformity of the seeding grain distance is guaranteed.
