[0023] Embodiment 1, refer to Figure 1~Figure 4 , which is the first embodiment of the present invention, provides a Forsythia suspensa stem remover.

[0024] In this embodiment, the Forsythia suspensa stem removing machine includes a frame 1, a roller 2, a stem removing knife 5 and an elastic member 6; a spherical feed guide is provided on the frame 1, and the Forsythia suspensa fruits are added into the feed guide, and the fruits are introduced into the roller 2 with the help of the curved surface of the feed guide; an external force is applied to drive the roller 2 to rotate, and during the rotation of the roller 2, the fruit stems of some fruits will be inserted into and pass through the stem leakage hole 4, and the fruit stems will be exposed on the outside of the roller 2. As the roller 2 rotates, the exposed fruit stems gradually approach the stem removing knife 5 and are cut off by the blade of the stem removing knife 5, thereby completing the fruit stem removal operation.

[0025] The elastic member 6 is preferably a spring. When the stem-removing knife 5 is in operation, the elastic member 6 is in an extended state. With the force provided by the elastic member 6, the blade is in contact with the outer cylindrical surface of the drum 2, ensuring continuous stem removal. When the fruit is mixed with hard impurities and the impurities are exposed through the stem-leaving hole 4, with the elastic force of the elastic member 6, the stem-removing knife 5 rotates on the frame 1 away from the drum 2 to avoid damage or curling of the blade of the stem-removing knife 5. With the combination of the drum 2 and the stem-removing knife 5, the stem of the Forsythia fruit can be quickly cut and removed, thereby improving the processing efficiency of the fruit, reducing the processing time, and saving the processing cost.

[0026] Example 2, refer to Figure 1~Figure 4 , which is the second embodiment of the present invention. On the basis of the first embodiment, the present embodiment further refines the number of the handle removing knives 5 and the elastic member 6, and selects a plurality of them. When one of the handle removing knives 5 becomes stuck, damaged, or rolled, it can be repaired and replaced separately without affecting the operation of other handle removing knives 5, thereby realizing online maintenance of the handle removing machine, reducing downtime for maintenance, and improving overall work efficiency.

[0027] Example 3, refer to Figure 1~Figure 5 , which is the third embodiment of the present invention. On the basis of the first embodiment, this embodiment further adds a plurality of push plates 7; in this embodiment, four are distributed along the circumferential direction of the drum 2, which are defined as one group, and five groups are distributed along the center line direction of the drum 2; the push plates 7 can push the fruit to gradually move from the inlet of the storage barrel cavity 3 to the outlet; as the drum 2 rotates, the fruit whose stalk is inserted into the stalk hole 4 will move synchronously with the drum 2, and as the height spatial position of the fruit gradually increases, the fruit stalk has the phenomenon of falling back into the storage barrel cavity 3. With the help of the push plates 7, the probability of the fruit stalk falling back can be reduced, and the efficiency of removing the fruit stalk can be improved.

[0028] Embodiment 4, referring to Figure 1~Figure 5 , which is the fourth embodiment of the present invention, is based on the first embodiment, and further adds a material guiding unit, a collecting member 11 and a material guiding tube 13, wherein the material guiding unit includes a material guiding member 1 8 and a material guiding member 2 10.

[0029] When in use, in this embodiment, the number of rollers 2 is preferably two, which are distributed at intervals in the upper and lower parts, namely the upper roller and the lower roller; the number of material guiding units is preferably one; the sides of the two rollers 2 are provided with stem removing knives 5; when working, the fruits of Forsythia suspensa first enter the upper roller, and as the upper roller rotates, the fruits gradually approach the material piece one, and fall downward through the leakage port 9, and with the help of the guidance of the material guiding piece 2 10, the fruits enter the lower roller, and with the help of the continuous stem removing operation of the upper and lower rollers, the efficiency and accuracy of fruit stem removal are improved.

[0030] The fruits after the stems are removed enter the collecting part 11 from the outlet of the lower cylinder, and then pass through the discharge port 12 at the lower part of the collecting part 11 into the guide pipe 13. The fruits are then collected and transferred to the next operation process. With the help of the residue leakage hole 14 of the guide pipe 13, the impurities such as the residue in the fruits are discharged to improve the purity of the fruits.

[0031] Example 5, refer to Figure 1 and Figure 6~Figure 13, which is the fifth embodiment of the present invention, because the fruit stalks of Forsythia suspensa fruits have straight stalks, curved stalks, and even curved stalks with a back bend, when passing through the roller 2, except for the straight stalks or stalks close to the straight stalks that can be inserted into the stalk hole 4, the rest of the curved stalks, curved stalks, etc. cannot be inserted into the stalk hole 4, resulting in that after the stalk removal operation by the roller 2 and the stalk removal knife 5, there are still some fruit stalks that cannot be removed, and manual screening is required. The process is cumbersome and there is a phenomenon of inadequate detection, resulting in poor consistency in the fruit stalk removal operation effect; therefore, on the basis of the first embodiment, this embodiment further adds a screening unit, and the screening unit includes a screening box 15, a screening member 16, a bracket 18, a transfer plate 19, and a linkage rod 20; wherein the number of the linkage rods 20 is preferably four, which are circumferentially distributed on the transfer plate 19. The screening member 16 is a left-right symmetrical member.

[0032] The screening element 16 includes a horizontal bar and a lifting bar. Vertical bars are provided at both ends of the lifting bar. The lifting bar is provided with a plurality of screening holes 17 for inserting fruit stalks. The two lifting bars are symmetrically distributed and defined as a fruit tray. The screening holes 17 are respectively located on the sides facing away from each other. Three fruit trays are spaced apart on the entire horizontal bar. Three sliding channels 49 are provided at the lower end of the screening box 15. The fruit tray and the vertical bars are slidably arranged in the sliding channels 49. The lifting bar and the two vertical bars just cover the cross-section of a sliding channel 49. When in use, the fruit support of the screening element 16 is located in the sliding channel 49, and a number of screening elements 16 are distributed in sequence along the direction of the sliding channel 49; first, add the fruits of Forsythia suspensa to the screening box 15, apply external force to drive the fruits to fall into the sliding channel 49, and insert the fruit stalks of some fruits into the screening holes 17; apply external force to drive the screening element 16 to slide upward along the sliding channel 49, and the screening element 16 pushes the fruits to slide upward synchronously; the top screening element 16 in the sliding channel 49 gradually approaches the upper port of the sliding channel 49 and leaves the upper port, and as the lifting rod of the first screening element 16 leaves the sliding channel 49, the fruits in the screening box 15 flow into the sliding channel 49 again and fall onto the lifting rod of the second screening element 16, and again some fruit stalks of the fruits are inserted into the screening holes 17, and this cycle is repeated to ensure that the fruits will not fall to the outside of the screening box 15 through the sliding channel 49.

[0033] External force is applied to drive the transfer plate 19 to rotate, and the transfer plate 19 rotates in the same direction with the four linkage rods 20; when the first screening element 16 leaves the upper end of the sliding channel 49, one of the linkage rods 20 just gradually approaches the screening element 16 and is clamped with the screening element 16, and with the help of the rotation of the quasi-transfer plate 19, the first screening element 16 gradually approaches the feed guide at the drum 2, and when the screening element 16 moves to the top of the feed guide, external force is applied to drive the linkage rod 20 to start rotating, and rotate one hundred and eighty degrees; after the rotation is completed, all the fruits inserted into the screening holes 17 fall into the feed guide, completing the fruit loading operation.

[0034] Then, an external force is applied to move the first screening element 16 to the bottom of the sliding channel 49, so as to form a cycle, and the fruits are screened again. After screening for a period of time, the fruit replenishment is stopped until the fruits in the screening box 15 have undergone a round of screening; the side wall of the screening box 15 is openable, and the side wall of the screening box 15 is opened to clean out the fruits left in the screening box 15, and the stem removal operation is performed separately, and the side wall of the screening box 15 is closed, and new fruit raw materials are continuously added to perform the screening operation again. Through the screening of the screening element 16, the fruit stems are classified, and the fruits with straight stems or nearly straight stems are transported to the drum 2 with the help of the screening element 16 for stem removal, thereby improving the purity of the fruits after stem removal; the fruits with curved or bent stems cannot be inserted into the screening hole 17, so they are left in the screening box 15, and the screening of the fruits is realized; the overall work efficiency, the accuracy of fruit stem removal, and the purity of the fruits are improved.

[0035] Example 6, refer to Figure 1 and Figure 6~Figure 13 , which is the sixth embodiment of the present invention. On the basis of the fifth embodiment, this embodiment further improves the specific structure of the screening element 16, and a through slot 1 21 is provided on the cross bar; at the same time, a clamping unit is added, and the clamping unit includes a locking pin 1 24 and an elastic member 25, and the elastic member 25 is preferably a spring; when in use, as the transfer plate 19 rotates, the linkage rod 20 gradually approaches and clamps into the through slot 1 21 with the locking pin 1 24 and the elastic member 25; the portion of the locking pin 1 24 exposed outside the slide slot 1 23 is a round Arc-shaped; when the linkage rod 20 is inserted into the through slot 1 21, the side wall of the through slot 1 21 squeezes the locking pin 1 24, so that the locking pin 1 24 squeezes the elastic member 25 along the slide slot 1 23, and the elastic member 25 contracts and accumulates elastic force; until the locking pin 1 24 is aligned with the slot 22, the elastic member 25 releases the accumulated elastic force, and the locking pin 1 24 slides away from the elastic member 25 and is inserted into the slot 22, completing the clamping connection between the linkage rod 20 and the screening member 16; ensuring that the screening member 16 can stably follow the transfer plate 19 to rotate synchronously.

[0036] Embodiment 7, reference Figure 1 and Figure 6~Figure 13 This is the seventh embodiment of the present invention. On the basis of the fifth embodiment, this embodiment further adds a flipping unit and a circulation reflux unit; the flipping unit is used to complete the flipping of the screening element 16, and the circulation reflux unit is used to circulate the screening element 16 to the bottom of the screening box 15, so as to realize the recycling of the screening element 16 and ensure the continuity of the screening operation.

When the linkage rod 20 with the screening element 16 is about to move to the top of the feed guide, the flip gear 27 gradually approaches the arc rack 26, and the teeth on the flip gear 27 are meshed with the teeth on the arc rack 26; with the meshing connection between the arc rack 26 and the flip gear 27, the arc-shaped end of the second lock pin 29 is separated from the groove 28, and the flip gear 27 drives the linkage rod 20 to start rotating, and the linkage rod 20 drives the screening element 16 to start rotating a certain angle, and finally dumps the fruits on the screening element 16 into the feed guide to complete the loading operation. Then, as the transfer plate 19 continues to rotate, the flip gear 27 is meshed with the second arc rack 26 on the bracket 18, and the linkage rod 20 rotates 180 degrees to return to the initial state, waiting for the next screening element 16 to be engaged.

[0038] When the screening element 16 is turned over, the screening element 16 turns over 180 degrees, and the clamping piece 32 is located below the clamping hole 31; then an external force is applied to drive the clamping piece 32 to slide upward until the clamping piece 32 is clamped into the clamping hole 31; at this time, the transfer plate 19 continues to rotate, the turning gear 27 is separated from the arc gear, and the linkage rod 20 stops rotating and continues to slide until it is separated from the screening element 16; at this time, an external force is applied to drive the clamping piece 32 and the screening element 16 to slide downward for a distance, and the height of the screening element 16 is lower than the height of the linkage rod 20; then, the clamping piece 32 is driven to rotate 90 degrees in the direction close to the receiving piece 33 and then stop rotating; then, the lifting plate 19 is started.
