[0002] Clinical observations have shown that Ginkgo leaves have high medicinal value and have good therapeutic effects on many diseases. Ginkgo leaves contain important chemical components for the treatment of cardiovascular and cerebrovascular diseases. The harvest of Ginkgo leaves provides important raw materials for pharmaceutical companies to produce Ginkgo preparations. Therefore, the domestic demand is relatively large. Ginkgo leaves not only have large sales in my country, but are also exported in large quantities abroad every year.

[0003] In order to ensure the normal growth of ginkgo trees without affecting the medicinal components of ginkgo leaves, the picking period of ginkgo leaves is generally between September and October, or even slightly earlier. At present, the main method of harvesting ginkgo leaves from planted ginkgo seedlings (1 to 1.5 meters high, with few branches) is manual picking, which is not only difficult to pick, but also easy to mix many branches in the leaves during manual picking, resulting in a low pass rate of ginkgo leaves after picking; at the same time, ginkgo leaves themselves contain a small amount of toxicity (ginkgolic acid), which may cause allergies in some pickers during the picking process, and the pickers need to bend down many times to pick during the picking process, which consumes a lot of physical energy, making the picking of ginkgo leaves difficult.

[0004] Therefore, a ginkgo leaf picking machine that can overcome the above-mentioned technical problems is badly needed. Utility Model Content

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and implementations. It is to be understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings.

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] like Figure 1 As shown, the utility model provides a ginkgo leaf picking machine, including two walking mechanisms, which are symmetrically arranged. The two walking mechanisms cooperate with each other so that the ginkgo leaf picking machine can walk steadily on the ground. Both walking mechanisms are equipped with lifting mechanisms, and the two lifting mechanisms are jointly equipped with a separation mechanism and a picking mechanism. The picking mechanism is used to pick the ginkgo leaves on the ginkgo tree seedlings, and the separation mechanism is used to separate the picked ginkgo leaves from the branches to avoid the subsequent secondary sorting of the picked ginkgo leaves; at the same time, the picking mechanism is located in front of the separation mechanism, and the picking mechanism and the separation mechanism are raised and lowered synchronously by the lifting and lowering of the lifting mechanism to ensure that the picking mechanism completes the picking of the ginkgo leaves.

[0034] In order to facilitate the delivery of the picked ginkgo leaves into the separation mechanism for separation, a dredging pipe 15 is connected between the picking mechanism and the separation mechanism, so that the ginkgo leaves picked by the picking mechanism can be transported to the separation mechanism through the dredging pipe 15 for separation of the ginkgo leaves and branches; at the same time, in order to facilitate the delivery of the separated ginkgo leaves out of the separation mechanism, a discharge pipe 5 is also provided on the separation mechanism, so that the ginkgo leaves separated by the separation mechanism can be delivered through the discharge pipe 5.

[0035] Through the cooperation of the walking mechanism, the lifting mechanism, the picking mechanism and the separating mechanism, when ginkgo leaves need to be picked, the walking mechanism operates to make the ginkgo leaf picking machine move forward, the picking mechanism grabs the ginkgo leaves, and the lifting mechanism drives the picking mechanism and the separating mechanism to lift and lower, so that the ginkgo leaves grabbed by the picking mechanism are picked from the ginkgo tree, and the picked ginkgo leaves are transported to the separating mechanism through the dredging pipe 15 for separation, and the separated ginkgo leaves are sent out through the discharging pipe 5, and the whole process realizes the picking of ginkgo leaves.

[0036] In the utility model, the picking mechanism includes a cross beam 13, both ends of which are respectively mounted on two lifting mechanisms, and the picking mechanism is mounted on the cross beam 13, and the picking mechanism extends downward on the cross beam 13, so as to facilitate the picking mechanism to pick ginkgo leaves.

[0037] like Figure 2As shown, the picking mechanism includes a mounting seat 10 and a plurality of clamps 12 hinged on the mounting seat 10, wherein the mounting seat 10 is fixedly mounted on the crossbeam 13 by screws, and the plurality of clamps 12 swing on the mounting seat 10, so that the plurality of clamps 12 are opened or closed, and the plurality of clamps 12 are olive-shaped in the closed state, that is, the plurality of clamps 12 form a chamber with a thick middle and thin ends in the closed state, so that the ginkgo leaves to be picked are wrapped in the plurality of clamps 12, at this time, in coordination with the lifting and lowering of the lifting mechanism, the clamps 12 in the closed state form a relative movement with the ginkgo sapling, the ginkgo branches are extracted from the lower end of the chamber, and the leaves on the ginkgo branches are retained in the chamber, thereby realizing the picking of ginkgo leaves. In the utility model, in order to facilitate the opening and closing of the plurality of clamps 12, a driving structure for driving the plurality of clamps 12 to close or open is also installed on the mounting seat 10.

[0038] like Figure 3 As shown, the driving structure includes a fixed frame 17 and a telescopic rod Ⅰ16, the fixed frame 17 is in a hollow cylindrical shape, the fixed frame 17 is mounted on the mounting seat 10, the telescopic rod Ⅰ16 can be mounted on the mounting seat 10, the telescopic rod Ⅰ16 can also be directly mounted on the crossbeam 13, and the central axis of the telescopic rod Ⅰ16 is in the same straight line with the central axis of the fixed frame 17, and the telescopic rod Ⅰ16 is located above the fixed frame 17; the fixed frame 17 is also provided with a fixed sleeve 11 outside the fixed sleeve 11, and a plurality of connecting rods 18 are hinged on the fixed sleeve 11, and the plurality of connecting rods 18 are hinged along the fixed sleeve 11 is evenly spaced in the circumferential direction, and the number of connecting rods 18 is equal to the number of clamping jaws 12, and the positions of multiple connecting rods 18 correspond to the positions of multiple clamping jaws 12 one by one; the extended end of the connecting rod 18 is hinged with a swing arm 19, the swing arm 19 is in a 7 shape, and both ends of the swing arm 19 are arc-shaped, one end of the swing arm 19 is hinged with the outer wall of the clamping jaw 12, and the other end of the swing arm 19 extends toward the center of the fixed frame 17; the output end of the telescopic rod I 16 extends into the fixed frame 17, and the inner ends of multiple swing arms 19 are connected to the output end of the telescopic rod I 16 through a connecting rope. The connecting rope here is a steel wire rope or a metal rod, and the inner end of the swing arm 19 is the end of the swing arm 19 extending toward the center of the fixed frame 17; at the same time, the inner end of the swing arm 19 is in an arc shape with a downward depression in the middle.

[0039] The mounting seat 10 is also provided with a sleeve 20, which is threadedly matched with the mounting seat 10. The sleeve 20 is screwed on the mounting seat 10 to move the sleeve 20 upward or downward on the mounting seat 10; the swing range of the swing arm 19 is adjusted by the up and down movement of the sleeve 20, thereby adjusting the opening degree of the clamping jaws 12. When the opening degree of the clamping jaws 12 needs to be increased, the sleeve 20 is screwed counterclockwise and the sleeve 20 moves upward; when the opening degree of the clamping jaws 12 needs to be reduced, the sleeve 20 is screwed clockwise and the sleeve 20 moves downward.

[0040] In order to ensure that the jaws 12 remain stable in the open or closed state, an inclined telescopic rope 14 can be connected between the outer wall of the jaws 12 and the crossbeam 13, that is, the number of telescopic ropes 14 is consistent with the number of jaws 12, and each jaw 12 is connected with a telescopic rope 14, and the telescopic rope 14 is a spring or a rubber rope, etc. When the jaws 12 are in the closed state, the telescopic rope 14 is in a stretched state, and when the jaws 12 are in the open state, the telescopic rope 14 is in a retracted state. When the telescopic rod I 16 is retracted, the telescopic rod I 16 pulls the connecting rope, and the connecting rope pulls the swing arm 19 to swing, the jaws 12 are retracted to the middle, and the telescopic rope 14 is stretched; when the telescopic rod I 16 is extended, the connecting rope loses the stretch of the telescopic rod I 16, and the swing arm 19 loses the pull of the connecting rope. At this time, the telescopic rope 14 pulls the jaws 12 to swing outwards through its own elastic force, so that the multiple jaws 12 are in the open state.

[0041] In order to facilitate the ginkgo leaves to be picked from the branches smoothly, the clamping end of the clamping jaw 12 is also provided with arm teeth 21, so that the multiple clamping jaws 12 can be closed better when they are closed, and the branches with ginkgo leaves can be prevented from being directly pulled out of the chamber due to the large opening at the lower end of the chamber when the multiple clamping jaws 12 are closed, thereby ensuring a better picking effect of the ginkgo leaves. In the utility model, the clamping end of the clamping jaw 12 is the end of the clamping jaw 12 away from the mounting seat 10.

[0042] In order to prevent the cavity from being blocked when the jaws 12 are in the retracted state, a reinforcing rod 22 may be installed on the inner wall of the jaws 12 to increase the friction in the cavity when the ginkgo leaves are picked. This not only prevents the picked ginkgo leaves from being squeezed and blocked in the cavity, but also improves the picking effect of the ginkgo leaves.

[0043] like Figure 4 As shown, in the utility model, the separation mechanism includes a separation chamber 3 which is jointly arranged at the upper ends of the two lifting mechanisms, the internal space of the separation chamber 3 is in a ┏ shape, and the separation chamber 3 is located behind the crossbeam 13, the inlet end of the dredging pipe 15 is connected with one of the clamping jaws 12, so that when the multiple clamping jaws 12 are retracted, the chamber formed by the multiple clamping jaws 12 is connected with the inlet end of the dredging pipe 15, and the outlet end of the dredging pipe 15 is connected with the interior of the separation chamber 3; a fully rotatable centrifugal drum is also installed in the separation chamber 3, and the ginkgo leaves entering the separation chamber 3 through the dredging pipe 15 are caused to enter the centrifugal drum by the rotation of the centrifugal drum, and the ginkgo branches are separated outside the centrifugal drum; in order to facilitate the delivery of the ginkgo leaves in the centrifugal drum, the inlet end of the discharge pipe 5 is connected with the interior of the centrifugal drum, so that the separated ginkgo leaves can be directly delivered through the discharge pipe 5.

[0044] In order to facilitate the separated branches to be sent out of the separation chamber 3, the bottom of the separation chamber 3 is a rotatable lower clamping plate 24. When the lower clamping plate 24 is flipped downward, the bottom of the separation chamber 3 is opened, and the separated branches are sent out of the separation chamber 3; at the same time, in order to facilitate the control of whether the picked ginkgo leaves enter the centrifugal drum for separation, the separation chamber 3 can also be provided with a rotatable upper clamping plate 23, and the upper clamping plate 23 is located above the lower clamping plate 24. When the picked ginkgo leaves need to enter the centrifugal drum for separation, the upper clamping plate 23 is flipped upward; the outlet end of the dredging pipe 15 is located between the upper clamping plate 23 and the lower clamping plate 24 and is connected to the upper part of the separation chamber 3. In order to facilitate the adjustment of the turning of the upper clamping plate 23 and the lower clamping plate 24, when the upper clamping plate 23 and the lower clamping plate 24 are installed, the rotating shaft on the upper clamping plate 23 and the rotating shaft on the lower clamping plate 24 both extend outward through the separation chamber 3, and a sleeve is set on the extended end of the rotating shaft, and a latch is set on the sleeve. At the same time, a socket with the rotating shaft as the center is opened on the outer wall of the separation chamber 3, and the socket can be used for the latch to be inserted, and there are two sockets, which correspond to the horizontal state and vertical state of the turning of the upper clamping plate 23 and the lower clamping plate 24, respectively, so that the upper clamping plate 23 and the lower clamping plate 24 remain stable after turning. Of course, the locking of the upper clamping plate 23 and the lower clamping plate 24 after turning over in the utility model can also be achieved by other structures.

[0045] In order to ensure the separation of ginkgo leaves and branches, the centrifugal drum includes two circular end plates 25, the outer ends of the two end plates 25 are provided with short shafts, the short shafts are supported on the side wall of the separation chamber 3 through bearings, and a plurality of polished rods 26 are connected between the two end plates 25, and the plurality of polished rods 26 are evenly spaced and arranged along the edge of the end plates 25, so that the centrifugal drum is cage-shaped. When the centrifugal drum rotates, the ginkgo leaves enter the centrifugal drum through the gap between the two adjacent polished rods 26, while the branches are intercepted outside the centrifugal drum, thereby achieving the separation of the ginkgo leaves and branches.

[0046] In addition, the separation chamber 3 is also provided with a storage chamber 27, which is connected to the interior of the centrifugal drum through a pipeline penetrating an end plate 25, so that the ginkgo leaves separated by the centrifugal drum can enter the storage chamber 27 through the pipeline; when the separation chamber 3 is provided with a storage chamber 27, the inlet end of the discharge pipe 5 is connected with the storage chamber 27, so that the separated ginkgo leaves first pass through the storage chamber 27 and then are sent out through the discharge pipe 5.

[0047] In order to ensure that the separated ginkgo leaves can be smoothly delivered through the discharge pipe 5 after passing through the storage chamber 27, a pumping pump is also installed on the discharge pipe 5, so that the separated ginkgo leaves can be delivered through the negative pressure principle; at the same time, in order to ensure that the picked ginkgo leaves can enter the separation chamber 3, a feeder can also be installed on the dredging pipe 15, which is mainly used for transporting plants such as leaves and grass.

[0048] In order to ensure the rotation of the centrifugal drum, a drive motor 28 is also installed on the side wall of the separation chamber 3. The output end of the drive motor 28 is connected to the short shaft on one of the end plates 25 through a reducer, so that the drive motor 28 drives one end plate 25 to rotate, thereby rotating the centrifugal drum.

[0049] The travel mechanism includes an outer cover installed at the lower end of the lifting mechanism, and a travel track 7 and a travel motor 6 for driving the travel track 7 are installed in the outer cover. The lifting mechanism includes an upper shell and a lower shell, the lower shell is installed on the travel mechanism, and the lower end of the upper shell is sleeved in the lower shell, so that the upper shell can move up and down in the lower shell, and the two ends of the crossbeam 13 are installed on the two upper shells, and the separation chamber 3 is installed on the two upper shells together; a telescopic rod II8 is also installed in the lower shell, and the output end of the telescopic rod II8 is fixed to the upper shell.

[0050] The ginkgo leaf picking machine provided by the utility model can also be equipped with a control module, a battery module 4, a photovoltaic power generation module, a display module, and an operating module 2, wherein the input ends of the telescopic rod Ⅰ16, the telescopic rod Ⅱ8, the drive motor 28, the travel motor 6, and the pumping pump are all electrically connected to the output end of the control module, the display module is bidirectionally electrically connected to the control module, the output end of the battery module 4 and the output end of the operating module 2 are electrically connected to the input end of the control module, and the output end of the photovoltaic power generation module is electrically connected to the input end of the battery module 4. The control module is used to control the telescopic rod Ⅰ16, telescopic rod Ⅱ8, drive motor 28, travel motor 6, and pumping pump. The display module is used to display the relevant parameters of the telescopic rod Ⅰ16, telescopic rod Ⅱ8, drive motor 28, travel motor 6, pumping pump, etc. in the control module. The display module can also send control instructions to the control module. The operation module 2 is used to send instructions to the control module to control the telescopic rod Ⅰ16, telescopic rod Ⅱ8, drive motor 28, travel motor 6, and pumping pump. The battery module 4 supplies power to the drive motor 28, travel motor 6, pumping pump, etc. The electricity generated by the photovoltaic power generation module is transmitted to the battery module 4 for storage. Here, the control module, battery module 4, photovoltaic discovery module, display module, and operation module 2 can all adopt the control module, battery module 4, photovoltaic discovery module, display module, and operation module 2 commonly used in agricultural machinery. The connection method between the photovoltaic power generation module and the battery module 4 can adopt the connection method between ordinary photovoltaic power generation and storage batteries. When the ginkgo leaf picking machine provided by the utility model is equipped with a battery module 4, a charging port 1 for charging the battery module 4 can also be provided on the ginkgo leaf picking machine.

[0051] Before the utility model is started, the staff adjusts the flipping of the upper clamping plate 23 and the lower clamping plate 24 so that the lower clamping plate 24 is in a horizontal state and the upper clamping plate 23 is in a vertical state, that is, the space between the upper clamping plate 23 and the lower clamping plate 24 is connected to the upper part of the separation chamber 3; then, the operator sets the relevant parameters through the display module, and the pumping pump, the drive motor 28, and the travel motor 6 are activated; then, the operating module 2 sends an instruction to the control module, and after receiving the instruction, the control module sends a start signal to the drive motor 28 and the travel motor 6. After receiving the signal, the drive motor 28 and the travel motor 6 start to operate, and the travel track 7 rotates slowly, thereby driving the picking machine to move forward.

[0052] The staff adjusts the telescopic degree of the telescopic rod II 8 through the operating module 2 according to the height of the ginkgo tree and the position of the leaves, so that the height of the picking mechanism just reaches the optimal height for picking.

[0053] The staff adjusts the telescopic rod Ⅰ16 through the operating module 2, and the output end of the telescopic rod Ⅰ16 extends, and the connecting rope loses the pulling on the swing arm 19. At this time, the telescopic rope 14 pulls the clamping jaws 12 to swing outward through its own elastic force, so that the multiple clamping jaws 12 are opened together; when the ginkgo leaves to be picked are located in the center of the multiple clamping jaws 12; the staff adjusts the telescopic rod Ⅰ16 through the operating module 2, and the output end of the telescopic rod Ⅰ16 contracts. The telescopic rod Ⅰ16 contracts and drives the connecting rope at the same time. The connecting rope pulls the swing arm 19 to swing, and the swing arm 19 drives the multiple clamping jaws 12 to retract. The multiple clamping jaws 12 retract and pull the telescopic rope 14 to extend, and the ginkgo leaves to be picked are grasped in the multiple clamping jaws 12.

[0054] The staff adjusts the telescopic rod Ⅱ8 through the operating module 2 to extend the telescopic rod Ⅱ8, and the telescopic rod Ⅱ8 pushes the upper shell to move upward, so that the crossbeam 13, the mounting seat 10, the clamping claw 12, the separation chamber 3, etc. move upward together. When the clamping claw 12 moves upward, the branches on the ginkgo tree are pulled out from the multiple clamping claws 12 that are interlocked, and the ginkgo leaves on the trunks are retained in the multiple clamping claws 12 that are interlocked, so that the ginkgo leaves can be picked.

[0055] The picked ginkgo leaves are fed into the separation chamber 3 through the dredging pipe 15 by the pumping of the pumping pump and / or the action of the feeder. The ginkgo leaves that have entered the separation chamber 3 are fed into the centrifugal drum through the gap between two adjacent bare rods 26 by the rotation of the centrifugal drum, while the branches remain in the separation chamber 3. The ginkgo leaves that have entered the centrifugal drum are fed out through the storage chamber 27 and the discharge pipe 5 in turn.

[0056] When it is necessary to send out the branches staying in the separation chamber 3, the upper clamping plate 23 and the lower clamping plate 24 are rotated so that the upper clamping plate 23 and the lower clamping plate 24 are in a vertical state, and the bottom of the separation chamber 3 is open. At this time, the branches in the separation chamber 3 automatically fall out from the bottom of the separation chamber 3, or the branches can be manually hooked out from the bottom of the separation chamber 3 using tools. Finally, the lower clamping plate 24 is rotated so that the lower clamping plate 24 is in a horizontal state, and the bottom of the separation chamber 3 is closed.

[0057] During the ginkgo leaf picking process of the utility model, the picking and separation of the ginkgo leaves are controlled and regulated by the control module, which ensures the stability and accuracy of the operation of the picking machine; at the same time, the battery module 4 provides electrical energy, which not only ensures the continuous operation of the picking machine, but also ensures the smooth progress of the picking process.
