Now, the operation process of the tuber mustard harvester is described with the base frame 5 at the highest point, the first half cylinder 41a and the second half cylinder 41b are relatively separated, and the positioning pins 428 are located in the upper extending grooves as starting points, at this time, the piston rod of the third lifting cylinder 23 is in a downward moving state, and the piston rod of the second push-pull cylinder 24 is in a contracting state, that is, the two walking feet 22 shown in fig. 1 are in an upright state. Meanwhile, for the sake of convenience of understanding, the first half cylinder 41a in this embodiment is set as the left half cylinder when viewed from the front in fig. 1, and the positioning pins 428 at both ends of the third cross bar 423 connected thereto are both located in the upper extension groove 55 of the front mounting plate in fig. 8; the second half cylinder 41b is set as the right half cylinder when viewed from the front in fig. 1, the positioning pins 428 at both ends of the fifth cross bar 425 connected thereto are located in the upper extension grooves 55 of the rear mounting plate in fig. 9, and at this time, referred to as a first position W1, the first lift cylinder 7a is first operated to move the base frame 5 downward, and the vegetable leaf removing mechanism 3 is driven downward, and in the process of moving downward, the annular vegetable leaf removing knife 31 cuts off the vegetable leaves above the vegetable head (although the diameter of the vegetable leaf removing knife 31 is relatively large, the root of the vegetable leaves is easily broken when pressed by the vegetable leaf removing knife 31 to achieve the purpose of removing the vegetable leaves), and the lower ends of both sides of the base frame 5 are also grounded and supported on the ground until the vegetable leaf removing knife 31 is located on the vegetable ground. In the downward moving process, the second lifting cylinder 7b acts therewith to move the first cross bar downward, and since the positioning pins are located in the upper extending grooves and can move downward along the same direction, the downward moving of the first cross bar can drive the link mechanism and the cylinder to move downward, when the lower end of the base frame 5 is grounded, the positioning pins are located at the second position W2 shown in fig. 4, and then, as the piston rod of the second lifting cylinder 7b and the first cross bar 421 continue to move downward, the positioning pins on the third cross bar 423 begin to slide obliquely downward and rightward along the lower track grooves of the track grooves on the front mounting plate, and the positioning pins on the fifth cross bar 425 also begin to slide obliquely downward and leftward along the lower track grooves of the track grooves on the rear mounting plate until pushing the respective one-way blocking pieces and then sliding into the lower extending grooves, in the closing process, the cutting edges of the knife bodies on the first half cylinder 41a and the second half cylinder 41b cut the vegetable roots, meanwhile, the vegetable heads are accommodated in the cylinder body, and the shape is shown in figure 1. And each locating pin is in the third position W3 shown in fig. 4 and 5. Then, the third lifting cylinder 23 and the second push-pull cylinder 24 are operated to move the piston rod of the third lifting cylinder 23 upwards, the piston rod of the second push-pull cylinder 24 extends forwards, at this time, the walking foot 22 leaves the ground and makes a forward stepping action under the pushing of the second push-pull cylinder 24, and at this time, the front part of the machine body 1 is supported on the ground through the base frame 5; then, the piston rod of the third lifting cylinder 23 moves downwards, so that after the walking foot 22 lands on the ground, the piston rod of the second push-pull cylinder 24 retracts backwards, and the machine body 1 and the equipment on the machine body are pulled to move forwards by one step. In the process, as long as the walking foot 22 lands, the first lifting cylinder 7a acts immediately to pull the base frame 5 to move upwards, and then drives the vegetable leaf removing mechanism 3 and the first cross bar 421 to move upwards, because the positioning pins are located in the lower extension grooves at the moment, the base frame can move upwards along the same trend, namely the first half cylinder 41a and the second half cylinder 41b are still in a folding state to clamp the vegetable leaves to move upwards, when the positioning pins move to the fourth position W4 of the track groove, the first push-pull cylinder 8 acts to pull the base frame 5 backwards, so that the base frame 5 rotates around the machine body by an angle together with the rotating shaft, at the moment, the base frame 5 is already located above the containing box 13, and simultaneously, along with the continuous upward movement of the piston rod of the second lifting cylinder 7b and the first cross bar 421, the positioning pins on the third cross bar 423 start to slide upwards and leftwards along the upper track groove of the track groove on the front mounting plate, and the positioning pins on the fifth cross bar 425 start to tilt upwards along the upper track groove on the rear mounting plate, The first half cylinder 41a and the second half cylinder 41b start to be relatively separated by sliding to the right until the positioning pins are located at the first position W1, and in the process, the vegetable heads in the cylinder 41 automatically fall into the containing box 13. Then the first push-pull cylinder 8 is reset, the base frame 5 is rotated to be in an upright state, the piston rod of the first lifting cylinder 7a starts to move downwards again, and the process is repeated in this way, and the harvesting of the preserved szechuan pickle is completed.

In reaping the in-process, the barrel is when cutting the vegetable root, centre gripping vegetable end, if smuggleing earth has been smugglied simultaneously, can fall through the hole 131 that falls of containing box 13 bottom, if simultaneously in order to improve the effect of going soil, can increase vibration mechanism (not shown in the figure) in containing box 13, shake the containing box as required, make earth fall fast. The containing box 13 can be made into a structure which can be turned relative to the machine body 1, when the vegetable heads are downloaded, one side of the containing box 13 can be lifted, the vegetable heads fall down from the other side of the containing box 13, and then the vegetable heads are timely removed from the containing box by matching with the vibration of the vibration mechanism.

When a ridge of preserved szechuan pickle is harvested, the harvester needs to turn around, at the moment, if the harvester shown in fig. 1 needs to turn right (when a person stands on the machine body and looks towards the front part of the machine body), the right walking foot 22 is not moved, the left walking foot 22 does stepping motion according to the mode, when the left walking foot 22 does lifting and stepping motion, the piston rod of the first lifting cylinder 7a descends, and the base frame 5 lands; when the left walking foot 22 lands on the ground, the piston rod of the first lifting cylinder 7a rises to make the base frame 5 leave the ground, and the process is repeated for many times, because the walking foot 22 is in spherical hinge relative to the piston rod of the third lifting cylinder 23, the whole machine body 1 rotates around the right walking foot 22 to turn, and when the end of the next ridge of vegetable field is reached, the preserved szechuan pickle is harvested according to the mode.

In order to ensure that the walking distance of each harvester is consistent with the distance between the front and back adjacent hot pickled mustard tuber of the variety value, simultaneously, in order to meet the requirement that the distance between the adjacent hot pickled mustard tuber of the same row and the number of the hot pickled mustard tuber of the same row of each ridge are respectively consistent with the configuration of the harvester, when the hot pickled mustard tuber seedlings are planted, the harvester is required to be used for carrying out jack planting, at the moment, a jack knife 44 is required to be replaced at the lower end of a cylinder body, the jack knife 44 is a columnar body with a pointed lower end, please refer to figure 10, when jacks are carried out, the first half cylinder body 41a and the second half cylinder body 41b do not need to be folded and opened, and only need to be lifted and descended, namely, piston rods of the first lifting cylinder 7a and the second lifting cylinder 7b move downwards, the base frame 5 lands, the walking feet start to carry out stepping action after the columnar bodies of the jack knife on the cylinder bodies are inserted into a vegetable field, and when the walking feet land, the piston rods of the first lifting cylinder 7a and the second lifting cylinder 7b move upwards, when the piston rod of the second push-pull cylinder retracts to the right position, the machine body 1 advances a distance between adjacent preserved szechuan picks, then the piston rods of the first lifting cylinder 7a and the second lifting cylinder 7b move downwards again to land and perform hole inserting actions, so that the hole inserting process during preserved szechuan pickle planting is repeatedly realized, the distance between the front and the back of the planted preserved szechuan picks, the distance between the left and the right adjacent preserved szechuan pickles and the number of preserved szechuan pickle plants in each ridge meet the requirements of a harvester during harvesting, and conditions are created for realizing machine harvesting.
