In this patent, the root-leaf separator is mainly composed of a separating frame and two sets of separating mechanisms mounted on the separating frame. Wherein, the separation frame is a frame body that extends the setting from beginning to end, and the front and back both ends of separation frame all correspond the rigid coupling together with the pay-off frame bottom. In this patent, the contained angle between the back and forth extension orbit of separation frame and the pay-off frame of top back section back and forth extension orbit is the acute angle that is less than or equal to 45 degrees. For convenience of description, this included angle is referred to as the separation angle. The separating mechanism is arranged at the middle rear part of the separating frame, one set of separating mechanism is arranged on each of the left side and the right side, and the two sets of separating mechanisms are symmetrically arranged. In this patent, every set of separating mechanism is including setting firmly the separation support on the separation frame corresponds the avris, installs the separation main shaft of vertical setting between every separation support front portion and the below separation frame corresponding part, installs the separation power device that the drive separation main shaft pivoted on the pay-off frame. The lower section of the separation main shaft is provided with a separation main gear, and the upper section of the separation main shaft is provided with a separation main grooved wheel. The front part of the separation frame is rotatably provided with a separation pinion, and the separation pinion and the separation main gear are arranged in a front-back corresponding manner. In the patent, the separating pinion and the separating main gear are sleeved with a separating chain ring, so that the three form a transmission fit relationship. For convenience, the direction inside the loop of the split link is referred to herein as inside and the direction outside the loop is referred to herein as outside. The separating chain ring is composed of a plurality of chain ring buckles hinged end to end, and the chain ring buckles can be sleeved and matched with the teeth of the separating main gear and the separating auxiliary gear, so that chain transmission matching is realized. The top surface or the bottom surface of the chain ring buckle is fixedly connected with an elastic frame which is a hollow frame body. The elastic slide way is arranged on the elastic frame and is transversely arranged, and the direction of the elastic slide way is from the inner side to the outer side of the annular track of the separating chain ring, namely the direction of the elastic slide way is consistent with the direction of the opening of the chain ring buckle. The elastic slide rails are inserted in the elastic slide ways in a sliding manner and can only slide along the elastic slide ways longitudinally. The inner end of the elastic slide bar, namely one end close to the separation master gear, is fixedly provided with an elastic limiting block, and the elastic limiting block mainly plays a role in preventing the elastic slide bar from slipping from the elastic slide way. The outer end of the elastic sliding rod is fixedly connected with an elastic U-shaped frame, the opening of the elastic U-shaped frame is arranged outwards and is arranged back to the separation main shaft. In this patent, the sides of the tension U-shaped frame (i.e., the sides on which the U-shaped tracks are located) are arranged laterally. An elastic transverse shaft is fixedly connected between two ends of the elastic U-shaped frame, and obviously, the elastic transverse shaft and the elastic sliding rod are vertically arranged in a transverse plane. The elastic cross shaft is sleeved with a plurality of elastic rollers which can freely rotate around the elastic cross shaft. Thus, a circle of a plurality of tightening rollers supported by a plurality of tightening U-shaped frames is formed on the periphery of the whole separating chain ring, and all the tightening rollers are positioned in the same plane to form a 'tightening roller chain' or 'tightening roller ring'. In this patent, still install elasticity elastic component (for example spring) on the elasticity frame, the main effect of elasticity elastic component makes elasticity slide bar elasticity slide to the outside to make elasticity stopper and elasticity press fit that the elasticity corresponds the portion with the elasticity frame. Thus, under the elastic action of the elastic member, the "elastic roller ring" has an inward contraction and outward extension "elasticity". In this patent, the separation props tight wheel is installed to separation frame both sides side, and the separation props tight wheel and separation chain link inboard press fit and roll cooperation. Under the tightening action of the separating and tightening wheel, the separating chain ring forms a straight chain segment at the inner side (the adjacent part of the two separating mechanisms) and an arc chain segment at the outer side (the separating and tightening wheel presses the separating chain ring outwards to form an outward convex arc). The elastic rollers of the two linear chain segments are elastically clamped together under the action of the elastic member, and an automatic aligning channel extending forwards and backwards is formed. Under the drive of the separation power device, the automatic aligning channel has the function of elastically clamping the article and conveying the article backwards. The front end of the automatic aligning channel is closely matched with the middle part of the total pulling channel corresponding to the front, namely close to but can not be touched. Thus, when the stem and leaf of carrot are held by the total drawing channel and move upwards and backwards, the root of carrot and the connection part of stem and leaf (hereinafter referred to as 'rhizome') automatically enter the automatic aligning channel when passing through the automatic aligning channel. In this patent, the automatic aligning channel and the total extracting channel are synchronously matched, that is, the whole carrot is kept in a vertical state in the backward conveying process, therefore, when the total extracting channel conveys the carrot stem leaves backward and upward, the automatic aligning channel can synchronously convey the 'rhizome' to move backward, that is, the whole carrot is in a vertical state. For convenience of description, this state is referred to as "synchronous conveyance state". In the synchronous conveying state, the total extracting channel is conveyed upwards and backwards, the automatic aligning channel is only conveyed backwards, the separation angle exists between the conveying tracks of the total extracting channel and the automatic aligning channel, and therefore the total extracting channel has the function of upwards extracting the whole carrot. When the top ends of the carrot roots are lifted to the automatic aligning channel (actually the bottom of the corresponding elastic roller), the carrot roots are thicker and can be blocked by the automatic aligning channel, so that the top ends of all the carrot roots are at the same height (the bottom edge of the automatic aligning channel), and the automatic aligning function is completed. In this patent, install turnip cutting mechanism on the back end among the separator, turnip cutting mechanism front end corresponds the setting with automatic alignment passageway rear end. The radish cutting mechanism comprises two disc-shaped cutting blades which are arranged on the left side and the right side of the separating frame through vertical cutter shafts, and adjacent parts of the two cutting blades are vertically overlapped to form a shearing part. The shearing part and the automatic aligning channel are arranged in a front-back corresponding mode, and the shearing part is located above the automatic aligning channel. Thus, when the 'rhizome' is output from the automatic alignment channel, the 'rhizome' is just cut by the cutting part, and the cutting and separation of the carrot root, the carrot stem and the carrot leaf are completed. In this patent, the separation main sheave is installed to separation main shaft upper segment, and the separation auxiliary sheave that corresponds the setting around with the separation main sheave is installed through the rotation of separation countershaft between the separation frame that separation support back end and below correspond, and the cover is equipped with the separation belt that makes both transmission fit on separation main sheave and the separation auxiliary sheave. Adjacent straight line sections of the two separation belts are closely matched and form a translation cutting channel which clamps the lower parts of the carrot stems and leaves and horizontally moves backwards, and the translation cutting channel and the automatic alignment channel can enable the whole carrot to be synchronously matched with one another in a vertical state and conveyed backwards. The front part of the translation cutting channel and the rear part of the automatic alignment channel are arranged up and down correspondingly, and the translation cutting channel can downwards cover the rear section of the automatic alignment channel and the overlapped part of the two cutting blades. The main effect that sets up translation cutting passageway is that aforementioned "rhizome" presss from both sides tight stem leaf of carrot again and the level is carried backward when moving to the shearing part by the automatic alignment passageway to guarantee that the shearing part is always pulled out the passageway and can not upwards pull out the carrot and lead to appearing shearing error when cutting the rhizome, played the effect of accurate cutting.
