[0042] like Figures 1 to 13As shown, an embodiment of the present invention provides a medicinal material and potato harvester, comprising two symmetrical side panels 1, with two sets of parallel feeding structures 4 fixedly connected between the two side panels 1; a material carrying protection structure 5, which is located on the feeding structure 4 and is connected to the feeding structure 4, and the material carrying protection structure 5 cooperates with the feeding structure 4 to transport the harvested crops, and at the same time protects the crops on the material carrying protection structure 5, to avoid the crops colliding with the material carrying protection structure 5 in the process of transporting the crops, causing damage to the surface, which directly affects the economic value, storage stability, safety and edible quality of the harvested crops; the material carrying protection structure 5 comprises a first limiting unit 51 and a second limiting unit 53 connected to the feeding structure 4, and the first limiting unit 51 and the second limiting unit 53 can realize the rapid installation and replacement of the material carrying protection structure 5, thereby reducing the maintenance time when the material carrying protection structure 5 is damaged, and at the same time For different crops, there is no need to replace other harvesters. The transportation problem of different crops can be solved directly by replacing the material carrying protection structure 5. The first limiting unit 51 and the second limiting unit 53 are connected to the material carrying unit 52. Several material carrying units 52 work in a cycle under the drive of the feeding structure 4, thereby driving the material between the material carrying units 52 to move, thereby realizing the feeding process; one end of the two side panels 1 is fixedly connected to the shovel structure 2, which is used to cut into the soil and shovel up the crops with the soil. The feeding structure 4 is tilted, and one end of the feeding structure 4 is located below the shovel structure 2. The end of the two side panels 1 away from the shovel structure 2 is connected to the soil screening structure 6, which is used to throw materials to achieve soil block crushing and crop separation. The top of the two side panels 1 is fixedly connected to the traction structure 3, which is used to connect the power source to achieve traction of the harvester, wherein the shovel structure 2, the soil screening structure 6 and the traction structure 3 are all existing technologies.

[0043] When harvesting medicinal tuber crops, the traction structure 3 is connected to a tractor or other power source to drive the harvester to move. During the movement, the shovel structure 2 is inserted into the soil. As the harvester moves, the shovel structure 2 shovels out the medicinal tuber crops inside the soil together with the soil. The shoveled medicinal tuber crops fall onto the carrying unit 52 installed on the feeding structure 4 under the push of subsequent crops. Driven by the driving device connected to the feeding structure 4, the feeding structure 4 is driven to transmit, thereby driving the carrying unit 52 to rotate in a circle. The medicinal tuber crops that rotate to the end of the feeding structure 4 will fall onto the soil screening structure 6 for soil screening, thereby separating the crops from the soil, and then realizing the harvest of the medicinal tuber crops.

[0044] like Figure 1 and Figure 2 As shown, the feeding structure 4 includes two transmission shafts 41 rotatably connected to the two side plates 1, the outer wall of the transmission shaft 41 is provided with four evenly distributed transmission wheels 42 and a rod adjustment disk 43, and a transmission rod belt 44 is provided between the corresponding transmission wheels 42 on the two transmission shafts 41.

[0045] One of the transmission shafts 41 is connected to the driving device on the side panel 1, so that the transmission shaft 41 is driven to rotate by the driving device. The rotation of the transmission shaft 41 drives the transmission wheel 42 and the adjusting rod disk 43 fixed on its outer wall to rotate, and then drives the transmission rod belt 44 to perform transmission work. The transmission of the transmission rod belt 44 drives the material carrying unit 52 installed on its surface to circulate.

[0046] like Figure 3 、 Figure 4 、 Figure 9 and Figure 10 As shown, the first limiting unit 51 and the second limiting unit 53 are both provided with a plurality of them, and the plurality of first limiting units 51 and the second limiting units 53 are evenly distributed on the outer wall of the transmission rod belt 44; the first limiting unit 51 includes a base 511 fixedly connected to the outer wall of the two transmission rod belts 44 located on the outside, and a cartridge 512 is fixedly connected to the top of the base 511, and a slot is provided at the top of the cartridge 512 corresponding to the position of the base 511, and limiting plates 517 parallel to each other are fixedly connected on both sides of the slot, and the cartridge The inner wall of 512 is provided with four annular evenly distributed protection grooves 513, the top of the protection groove 513 is fixedly connected to the first elastic strip 514, and the bottom of the protection groove 513 is fixedly connected to the second elastic strip 515. The thickness of the first elastic strip 514 and the second elastic strip 515 gradually changes from thin to thick from the middle to the two ends, so that when the middle part of the first elastic strip 514 and the second elastic strip 515 is impacted, it is easier to deform, thereby forming a buffer and reducing the impact force. The top of the second elastic strip 515 is connected to the first elastic strip 514. The guide strips 516 are fixedly connected to the edges of the inner walls of the two opposite sides of the cartridges 512. The guide strips 516 are outward-turned and connected to the inner walls of the cartridges 512. The guide strips 516 make it easier for the connecting rod 522 to be inserted into the interior of the cartridges 512. The second limiting unit 53 includes two limiting vertical plates 531 fixedly connected to the two inner transmission rod belts 44 and symmetrically distributed on the surface wall. Semicircular grooves are opened on the opposite sides of the two limiting vertical plates 531. The top of the limiting vertical plates 531 is The top of the semicircular groove is fixedly connected to a fourth elastic strip 534 in an outward-turned shape, and a stopper 535 is fixedly connected to one side of the fourth elastic strip 534. The curvature of the side wall of the stopper 535 is greater than the curvature of the bottom, so that the connecting rod 522 is easier to enter the semicircular groove when squeezed, and is not easy to slide out of the semicircular groove. The limiting vertical plate 531 is fixedly connected to the bottom of the semicircular groove with a third elastic strip 532, and the connecting rod 522 can be buffered by the third elastic strip 532. Sockets 533 are provided on both sides of the limiting vertical plate 531.

[0047] like Figures 4 to 6As shown, the material carrying unit 52 is connected by two connecting rods 522 and a lifting rod 521. The diameters of the connecting rod 522 and the lifting rod 521 are consistent, and the diameter of the connecting rod 522 is slightly smaller than the diameter of the cartridge 512 and the semicircular groove. The two ends of the lifting rod 521 are rotatably connected to the connecting rod 522 respectively. One end of the connecting rod 522 is fixedly connected to a card plate 5221. The thickness of the card plate 5221 is less than the distance between the two limiting plates 517. The outer walls of the lifting rod 521 and the connecting rod 522 are fixedly connected to a plurality of groups of evenly distributed honeycomb rings 57. The honeycomb ring 57 is connected to the material protecting unit 56. The utility model comprises a rotation unit for realizing the mutual rotation of the lifting rod 521 and the connecting rod 522; the rotation unit comprises a protruding rod 5211 fixedly connected to both ends of the lifting rod 521, and the connecting rod 522 is fixedly connected to a U-shaped rod 5222 at one end close to the lifting rod 521. The lifting rod 521 and the connecting rod 522 are rotationally connected via a rotating shaft between the protruding rod 5211 and the U-shaped rod 5222. The outer walls of the protruding rod 5211 and the U-shaped rod 5222 are both provided with external threads, and a retaining sleeve 55 is provided on the side of the lifting rod 521 close to the protruding rod 5211, and the inner wall of the retaining sleeve 55 is provided with an internal thread compatible with the external thread.

[0048] When installing the material carrying unit 52, screw the retaining sleeve 55 to one side of the protruding rod 5211, lift the lifting rod 521, and then the two connecting rods 522 can rotate freely at both ends of the lifting rod 521. When installing, first align the outer ends of the two connecting rods 522 with the corresponding clamping cylinders 512, press the lifting rod 521, so that the connecting rods 522 at both ends of the lifting rod 521 slide into the guide bar 516 under the guidance of the guide bar 516, and at the same time, the clamping plate on the connecting rod 522 5221 is inserted between the two limiting plates 517. As the lifting rod 521 is pressed down, the connecting rod 522 will contact the two fourth elastic strips 534. Under the continuous squeezing force, the outer wall of the connecting rod 522 will stretch the two fourth elastic strips 534, and at the same time drive the upper half of the limiting vertical plate 531 to deflect outward until the connecting rod 522 slides into the semicircular groove along the stop block 535. The limiting vertical plate 531 returns to its original position under the action of its own elastic force, thereby tightening the connecting rod. The outer surface of 522 is clamped and limited. When the connecting rod 522 is squeezed into the second limiting unit 53, the lifting rod 521 and the two connecting rods 522 are in a straight line, and then the retaining sleeve 55 is rotated to the outer wall of the protruding rod 5211 and the U-shaped rod 5222, thereby limiting the protruding rod 5211 and the U-shaped rod 5222 to prevent rotation between the protruding rod 5211 and the U-shaped rod 5222. The cartridge 512 will limit the connecting rod 522 to prevent rotation during transportation. When delivering crops, if the connecting rod 522 and the lifting rod 521 fall off and the material carrying unit 52 needs to be disassembled, the opposite operation can be performed. When the medicinal tuber crops fall and hit the connecting rod 522, the connecting rod 522 will transfer the impact force it receives to the first elastic strip 514, thereby forming a buffer, reducing the force between the medicinal tuber crops and the connecting rod 522. At the same time, the second elastic strip 515 will deform accordingly under the deformation and extrusion of the first elastic strip 514, forming a second buffer.

[0049] like Figure 4 、 Figure 7 and Figure 8 As shown, each group of honeycomb rings 57 is formed by a number of hexagonal rings connected in a ring shape, and the hexagonal ring position protecting unit 56 provides an installation position and a buffer space, while preventing soil from entering the gap between the protecting unit 56 and the connecting rod 522. The protecting unit 56 is formed by a number of groups of protecting rings 561 connected end to end, and each group of protecting rings 561 is annularly sleeved on the honeycomb ring 57. The inner side of the protecting ring 561 is fixedly connected with a shock-absorbing strip 562 corresponding to the several hexagonal rings. The thickness of the protecting ring 561 and the shock-absorbing strip 562 gradually changes from thin to thick from the middle to the two ends. The shock-absorbing strip 562 has an eight-shaped structure, and the bottom end of the shock-absorbing strip 562 is fixedly connected to the inner walls on both sides of the hexagonal ring.

[0050] When the medicinal tuber crops fall from the shoveling structure 2 onto the material carrying unit 52, the medicinal tuber crops first come into contact with the protective ring 561. Since the protective ring 561 is an outwardly convex ring structure, when it is impacted by the medicinal tuber crops, the impact part is the middle part. Since the middle part is more easily deformed, the deformed protective ring 561 will drive the shock-absorbing strip 562 to bend and deform, thereby absorbing the impact force of the crop falling. At the same time, the protective ring 561 is made of rubber, and it itself will also provide a certain degree of protection for the crop.

[0051] like Figures 11 to 13 As shown, the second limiting unit 53 is connected to a protective unit 54, which includes a sleeve 541 sleeved on two limiting vertical plates 531. The sleeve 541 is made of elastic material. The sleeve 541 can prevent crops from contacting the second limiting unit 53 when they fall, thereby preventing the crops from colliding with the second limiting unit 53 and causing damage. The sleeve 541 is a U-shaped structure, and the inner walls on both sides of the sleeve 541 are fixedly connected to the limiting balls 542 at positions corresponding to the sockets 533; the limiting balls 542 are composed of a plurality of elastic strips in a ring array, and the outer shape of the limiting balls 542 is adapted to the shape of the sockets 533.

[0052] When installing the protective unit 54, bend the sleeve plate 541 to both sides so that the sleeve plate 541 is sleeved on the second limiting unit 53, and at the same time align the limiting ball 542 with the socket 533, and then press both sides of the sleeve plate 541 so that the limiting ball 542 is deformed under the pressure of the hole 533, until the entire limiting ball 542 enters the inside of the socket 533, thereby fixing the sleeve plate 541 on the second limiting unit 53.

[0053] The working principle of the technical solution provided by the present invention is as follows: when installing the material carrying unit 52, the retaining sleeve 55 is screwed to one side of the protruding rod 5211, and the lifting rod 521 is lifted. At this time, the two connecting rods 522 can rotate freely at both ends of the lifting rod 521. When installing, the outer ends of the two connecting rods 522 are aligned with the corresponding clamping cylinders 512, and the lifting rod 521 is pressed so that the connecting rods 522 at both ends of the lifting rod 521 slide into the guide bar 516 under the guidance of the guide bar 516. At the same time, the clamping plate 5221 on the connecting rod 522 is clamped into the two ends. When the second limiting unit 53 is pressed into position, the lifting rod 521 is pressed downward, and the connecting rod 522 comes into contact with the two fourth elastic strips 534. Under the continuous squeezing force, the outer wall of the connecting rod 522 will stretch the two fourth elastic strips 534, and at the same time drive the upper half of the limiting vertical plate 531 to deviate outward until the connecting rod 522 slides into the semicircular groove along the stop block 535. The limiting vertical plate 531 returns to its original position under the action of its own elastic force, thereby clamping and limiting the outer surface of the connecting rod 522. When the connecting rod 522 is squeezed into the second limiting unit 53, the lifting rod 521 and the two connecting rods 522 are in a straight line, and then the retaining sleeve 55 is rotated to rotate the retaining sleeve 55 to the outer wall of the protruding rod 5211 and the U-shaped rod 5222, thereby limiting the protruding rod 5211 and the U-shaped rod 5222 to prevent rotation between the protruding rod 5211 and the U-shaped rod 5222. The cartridge 512 will limit the connecting rod 522, and then install the protective unit 54, bend the sleeve 541 to both sides so that the sleeve 541 is sleeved on the second limiting unit 53, and at the same time align the limiting ball 542 with the socket 533, and then press the sleeve 541. On both sides, the limiting ball 542 is deformed under the extrusion of the hole 533 until the entire limiting ball 542 enters the inside of the hole 533, thereby fixing the sleeve 541 on the second limiting unit 53, thereby completing the installation of the material carrying unit 52. After the installation is completed, a rubber arc plate parallel to the first limiting unit 51 is installed on the inner side of the side panel 1 near the top of the first limiting unit 51. The rubber arc plate is a concave arc structure. The first limiting unit 51 is shielded by the rubber arc plate with an arc structure to prevent the crop from contacting the first limiting unit 51 and causing damage.

[0054] When harvesting medicinal tuber crops, the traction structure 3 is connected to a tractor or other power source to drive the harvester to move. During the movement, the shovel structure 2 is inserted into the soil. As the harvester moves, the shovel structure 2 shovels out the medicinal tuber crops inside the soil together with the soil. The shoveled medicinal tuber crops are pushed by the subsequent crops and fall onto the carrying unit 52 installed on the feeding structure 4. The fallen medicinal tuber crops first connect with the protective ring 561. Since the protective ring 561 is an outwardly convex annular structure, When impacted by medicinal herb and tuber crops, the impact site is the middle site. Since the middle site is more easily deformed, the deformed protective ring 561 will drive the shock-absorbing strip 562 to bend and deform, thereby absorbing the impact force of the crop falling. At the same time, the connecting rod 522 will act on the first elastic strip 514 to form a buffer, reducing the force between the medicinal herb and tuber crops and the connecting rod 522. At the same time, the second elastic strip 515 will deform accordingly under the deformation and extrusion of the first elastic strip 514, forming a second buffer.
