However, the potato-to-impurity mixture after mechanized combine harvesting often contains impurities such as vines, stubble, residual film, hard dry soil clods, and wet clay clods. Therefore, separating the potato soil, vines, and film is a crucial step in potato harvesting and cleaning. For potato combine harvesters, the cost of manual picking and removing impurities is constantly increasing, making it difficult to meet market demands and severely restricting industry development. It is reported that the sorting and impurity removal stage accounts for about 70% of the labor cost during potato combine harvesting. High impurity rates and severe skin damage are bottlenecks restricting the current efficient and low-loss mechanized potato harvesting, hindering industry development.

[0007] Its working principle is as follows: The potato mixture after mechanized combined harvesting usually contains impurities such as vines, stubble, residual plastic film, dry and hard soil clods, and sticky and wet soil clods. When the vine and film removal and impurity removal device is working, the potato mixture is first conveyed to the vine and film removal device by the feeding mechanism and falls onto the buffer plate. The impurity removal holes evenly distributed on the buffer plate perform preliminary cleaning and impurity removal of small impurities such as broken soil in the potato mixture. After the preliminary impurity removal, the potato mixture falls onto the vine and film removal belt after passing through the buffer plate. The flexible protrusions evenly distributed on the surface of the vine and film removal belt can effectively buffer the impact force when the potatoes fall, preventing the potatoes from being broken, abraded, or mechanically damaged by external forces. Driven by the drive device I, the vine and film removal belt conveys the potato mixture towards the guide plate. Impurities such as vines, stubble, and plastic film can pass through the gap between the guide plate and the vine and film removal belt, realizing the cleaning and separation of flexible impurities.

[0008] Because the cleaning requirements for the potato mixture after harvesting by the potato combine harvester vary, the angle between the guide plate and the vine and film removal frame port can be adjusted by adjusting the relative position of the adjusting column slider on the guide rail, thereby adjusting the guiding effect of the vine and film removal device. Impurities such as vines, stubble, and mulch film pass through the gaps and are thrown off by the vine and film removal belt, completing the vine and film removal process of the potato mixture. Even after removing vines, stubble, and mulch film, the potato mixture often still contains dry hard clods and sticky wet clods. After vine and film removal, the potato mixture moves along the guide plate towards the vibrating impurity removal device and falls onto the vibrating impurity removal belt. The vibrating impurity removal belt is achieved by a shaking mechanism arranged on both sides of the vibrating impurity removal frame. The shaking mechanism is powered by drive device II through main shaft II and sprocket transmission, driving the eccentric wheel to rotate. The planetary rod located in the eccentric wheel groove drives the shaking rod to push the shaking plate to move up and down reciprocally, thus achieving the vibration of the vibrating impurity removal belt. Small stones, clods of soil, and other blocky impurities move towards the side of the vibrating impurity removal belt that is closer to the vine and film removal device under the excitation of the vibrating impurity removal belt and fall to the ground. Potatoes roll from the vibrating impurity removal belt to the potato guiding device. The W-shaped guide plate of the potato guiding device, which is covered with flexible material, diverts the potatoes into the material boxes on both sides of the vibrating impurity removal device.

[0009] Compared with existing technologies, this invention, due to the uniformly arranged impurity removal holes on the buffer plate, can perform preliminary cleaning and impurity removal of fine impurities such as broken soil in the potato-mixture mixture; it fully utilizes the interaction between the guide plate and the vine and film removal belt, and through the gap between the guide plate and the vine and film removal belt, it achieves the separation of flexible impurities such as vines, root stubble, and residual film, and can prevent the occurrence of flexible impurities such as vines and residual film from entangled in key components, thus affecting the reliability of operation; due to the adoption of the "cross groove" adjustment mechanism, the angle between the guide plate and the vine and film removal frame port can be adjusted by adjusting the relative position of the adjusting column in the guide rail groove, thereby adjusting the amount of material entering the vibrating impurity removal device after vine and film removal, so as to achieve scientific and reasonable control for different cleaning conditions; due to the setting of the "W-shaped" potato guiding device, after vibration impurity removal, Under the action of the vibrating impurity removal belt, the potatoes are diverted to the material boxes on both sides of the vibrating impurity removal frame. On the one hand, the "W-shaped" potato guiding device is covered with flexible material. On the other hand, the potatoes fall from the vine and film removal belt onto the flexible vibrating impurity removal belt, which can reduce the damage to the potato skin. Therefore, the double loss reduction protection can realize the loss reduction and prevention of potatoes during the process of guiding them into the boxes. Due to the setting of the shaking mechanism, the eccentric wheel swings under the action of the drive device II. The planetary rod makes a circular motion in the eccentric wheel groove, which in turn drives the shaking rod to move up and down reciprocally. The shaking rod applies a vibration effect to the shaking plate. The shaking plate transmits the vibration effect to the vibrating impurity removal belt. As a result, small stones, small soil clods and other blocky impurities that fall on the vibrating impurity removal belt move towards the side closer to the vine and film removal device under the vibration effect and are thrown to the ground, so as to achieve the purpose of efficient and low-loss separation of blocky impurities. Therefore, the present invention can achieve efficient cleaning and separation of both flexible and lumpy impurities in potato and offal mixtures, and the cleaning amount of potato and offal mixtures can be adjusted according to different cleaning conditions to reduce and prevent losses.
