[0040] The fan adjustment element 54 includes a fan adjustment vertical bar 541, a fan adjustment cylinder 540, a longitudinal connecting plate 542 and a fan connecting shaft 543. The outer top of the fan adjustment vertical bar 541 is rotatably connected to the fan adjustment rotating bar 141. The fan adjustment cylinder 540 is rotatably installed in the adjustment turntable 151, and the output shaft of the fan adjustment cylinder 540 is connected to the middle part of the outer side of the fan adjustment vertical bar 541. The inner end of the longitudinal connecting plate 542 is connected to the bottom of the fan adjustment vertical bar 541. A fan connecting turntable 544 is protruded from the outer end of the top surface of the longitudinal connecting plate 542. The middle part of the fan connecting shaft 543 is rotatably installed in the fan connecting turntable 544, and the fan connecting shaft 543 is provided with multiple fan adjustment connecting platforms 545 at intervals along the length direction. The multiple fan adjustment connecting platforms 545 are respectively connected to the bottom of multiple air guide tubes 55.

[0041] For example, in one embodiment: a stem discharge trough is concavely provided at one end of the top surface of the top cover 13, and a discharge hopper is convexly provided at the stem discharge trough. A collection bag is sleeved in the discharge end at the bottom of the top cover 13.

[0042] For example, in one embodiment, before use, the connecting drag platform 122 is installed on the drag hook end of the tractor. When pulling peanuts, the tractor is started to pull the device forward, and at the same time, the driving motor is started to drive the main digging roller 21 to rotate, and the first transmission wheel 211 is driven to rotate, and its power is synchronously transmitted along the second transmission belt to the second transmission wheel 221, the five third rotating wheels 411, the fifth rotating wheel 436 and the sixth rotating wheel 521, so that the transmission pulling roller 22, the five screening separation rollers 41, the fan shaft 52 and the vibration drive shaft 431 rotate synchronously. When the main digging roller 21 rotates, multiple digging hooks 201 therein will rotate synchronously with it, thereby pulling out the peanut plants in the field. Since the multiple driven sub-digging hooks 240 protruding from the top of the digging cover net 23 are respectively arranged in an alternating manner with the multiple digging hooks 201, when the main digging roller 21 pulls the peanut plants and rotates, the multiple driven sub-digging hooks 240 and the multiple digging hooks 201 will rotate and screen the peanut fruits and soil at the bottom of the peanut plants, and send them to the transfer and pulling roller 22 as they rotate. Then, they are transferred and transported to the five screening and separation rollers 41 via the transfer and pulling roller 22. The pulled peanut plants are separated and screened by the rotation of the five screening and separation rollers 41, so that the peanut fruits in the peanut plants fall from the adjusting screen 42 to the vibrating conveying plate 441 and the vibrating screening plate 442, and the stems in the peanut plants fall to one side of the field through the stem discharge trough and discharge hopper of the top cover 13. At the same time, due to the rotation of the vibration driving shaft 431, the two eccentric wheels 432 will rotate synchronously, and then the two vibration connecting columns 433 will move along. Since the ends of the two vibration connecting columns 433 away from the eccentric wheels 432 are respectively rotatably connected to the middle parts of the two vibration driving plates 435, the two vibration driving plates 435 will rotate around the two ends of the vibration mounting shaft 434 respectively, and then the vibration conveying disk 441 and the vibration screening disk 442 will shake, so that the peanuts falling into them will follow the vibration conveying, and the vibration conveying disk 441 will convey the peanuts falling into it to the vibration screening disk 442, and then the vibration screening disk 442 will vibrate and convey them from the bottom of the top cover 13 to the collection bag for collection.

[0043] For example, in one embodiment, when the amount of peanuts in the collection field is large or the diameter of the peanut fruits is large, the rotation adjustment motor on the first rotating shaft 241 is started, so that the first rotating shaft 241 rotates, the first cam 245 rotates accordingly, the plucking adjustment rotating bar 242 moves accordingly, the second cam 246 moves accordingly, the plucking adjustment roller 243 rotates, and the multiple driven sub-plucking hooks 240 on the plucking adjustment roller 243 move inwardly accordingly, so that the protrusion of the multiple driven sub-plucking hooks 240 on the plucking adjustment roller 243 from the plucking cover net 23 is reduced. At the same time, due to the adjustment of the plucking roller 243 and the multiple driven sub-plucking hooks 240 on the plucking adjustment roller 243, the plucking adjustment roller 243 is connected to the plucking adjustment roller 243. A first transmission belt is sleeved between the removing rollers 244. Adjusting the rotation of the removing rollers 243 will cause the multiple driven removing rollers 244 to rotate accordingly, thereby causing the protrusions of the multiple driven sub-pulling hooks 240 on the multiple driven pulling rollers 244 from the digging cover net 23 to decrease accordingly, thereby increasing the distance between the multiple driven sub-pulling hooks 240 and the multiple digging hooks 201, thereby preventing the peanut fruits from being torn, fallen off or crushed due to the large amount of peanut fruits or the large diameter of the peanut fruits when the peanut fruits and soil at the bottom of the peanut plants are rotary screened due to the large distance between the staggered driven sub-pulling hooks 240 and the digging hooks 201, thereby affecting the peanut harvest.

[0044] At the same time, the two screen adjusting cylinders 45 will be started synchronously, so that the output shafts of the two screen adjusting cylinders 45 will retract synchronously, and then the two active adjusting slides 422 will follow and move downward along the two screening adjusting slots 119 respectively, and the driven adjusting slide 421 will follow and move downward along the driven adjusting slot 118, so that the distance between the adjusting screen 42 and the five screening and separation rollers 41 will increase synchronously, thereby preventing the distance from being too close, which will cause the peanut fruits to be damaged or crushed when the five screening and separation rollers 41 rotate to remove the peanut plants, affecting the peanut harvest.

[0045] For example, in one embodiment: when the second transmission belt transmits power, the sixth rotating wheel 521 will rotate accordingly, and then the fan shaft 52 will rotate accordingly, so that the multiple blowing fan blades 53 will rotate and generate a blowing airflow, and the blowing airflow will, under the guidance of the air guide tube 55, impact the peanuts and residual soil that fall from the vibrating conveying plate 441 to the vibrating screening plate 442, and then the residual soil that may be generated when the five screening and separation rollers 41 rotate to thresh the peanut plants will be blown away to prevent too much soil from entering the collection bag. At the same time, the blowing airflow will impact the stalks of the peanut plant at the top, accelerating the discharge of the stalks from the stalk discharge trough.

[0046] In addition, when the screen adjusting cylinder 45 and the rotating adjusting motor are adjusted according to the diameter of the peanut fruit, the fan adjusting cylinder 540 is started synchronously, so that the output shaft of the fan adjusting cylinder 540 extends / retracts, and then the fan adjusting vertical bar 541 moves, and then the longitudinal connecting plate 542 moves, and then the fan connecting shaft 543 moves, and then the multiple air guide ducts 55 move, so that the blowing angles of the blown-away airflows in the multiple air guide ducts 55 change, thereby preventing the direct impact of the blown-away airflow when the diameter of the peanut fruit is small, causing the peanut fruit to be blown away, resulting in waste of peanut fruit.
