Description

Technical Field

[0001] The present invention belongs to the technical field of ginkgo leaf picking equipment, and particularly relates to a ginkgo leaf harvesting mechanism. Background Art

[0002] Ginkgo leaves have high medicinal value and have good therapeutic effects on many diseases. There are important chemical components for treating cardiovascular and cerebrovascular diseases in ginkgo leaves. Among them, the harvest of ginkgo leaves provides important raw materials for pharmaceutical enterprises to produce ginkgo preparations. The period when the content of ginkgo flavonoids and ginkgolides in ginkgo leaves is the highest is from May to August every year, especially in the first ten days of August. At this time, the ginkgo leaves are dark green, thick and large, and the content of flavonoids and lactones in the leaves is the highest, which is considered the best leaf picking period. The existing harvesting methods mainly rely on manual picking, which is difficult to pick, and when manually picking leaves, it is easy to break branches, reducing the harvest in the coming year. Moreover, the picked leaves are easily mixed with many impurities, resulting in a low qualification rate of the picked ginkgo leaves. In addition, ginkgo leaves themselves contain a small amount of toxicity (ginkgolic acid), so some pickers may have allergic reactions during the picking process. At the same time, the existing mechanized picking of ginkgo leaves has low productivity and serious damage to branches. Especially when the maturity of the leaves is low, the amount of fallen branches and leaves is too large, affecting the growth and development of the tree body, the photosynthesis of the leaves and the fruit yield. Summary of the Invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a ginkgo leaf harvesting mechanism, which at least partially solves the above technical problems.

[0004] The technical solution adopted by the present invention is as follows: A ginkgo leaf harvesting mechanism includes a picking vehicle for moving.

The dragging ropes arranged at the lower end of the connection frame sequentially penetrate through the upper pressing plates movably, and multiple groups of lower pressing plates for fixing are evenly installed at equal intervals on the dragging ropes arranged at the lower end of the connection frame. The number of the lower pressing plates is the same as the number of the upper pressing plates, and the upper pressing plates and the lower pressing plates are placed alternately. The upper walls of the lower pressing plates are made of elastic materials, which is convenient for protecting the ginkgo leaves.

[0007] Among them, a mounting plate one is provided on the upper wall of the connection frame of the first connection component, and a mounting plate two is provided on the upper wall of the connection frame of the second connection component. The mounting plate one and the mounting plate two are placed opposite to each other. A folding bladder one is provided between the mounting plate one and the mounting plate two, and the folding bladder one, the mounting plate one and the mounting plate two are hermetically connected.

[0008] Preferably, a fixing frame is installed on the bottom wall of the lowermost lower pressing plate of the second connection component, and a flexible storage member is installed at the lower end of the fixing frame. The flexible storage member has a cavity structure and is connected to the fixing frame in a through manner. A storage frame is provided on the upper wall of the first support plate, and the upper end of the storage frame is connected to the flexible storage member in a through manner. The ginkgo leaves picked by the second connection component fall into the fixing frame and then fall into the storage frame through the flexible storage member.

[0009] As a preferred embodiment of the present invention, the storage and cleaning component includes a storage box, which is arranged on the bottom wall of the first support plate, and the lower end of the storage frame is connected to the space inside the storage box. The storage and cleaning component also includes a movable frame, which is movably arranged in the storage box, and the bottom wall and the upper wall of the movable frame are connected to the bottom wall and the upper wall of the storage box by ball bearings to reduce friction. A folding capsule 2 and a spring are installed between the movable frame and the inner wall of the storage box, and the spring is arranged in the folding capsule 2. The folding capsule 2, the movable frame and the storage box are sealed.

[0010] Among them, a ventilation cavity 2 is provided in the side wall of the storage box close to the folding bag 2, and a ventilation cavity 1 is provided in the first support plate. The ventilation cavity 2 is through-connected with the folding bag 2, and one end of the ventilation cavity 1 is through-connected with the upper end of the ventilation cavity 2. A ventilation pipe is also installed on the upper wall of the first support plate, and the lower end of the ventilation pipe is through-connected with the ventilation cavity 1, and the upper end of the ventilation pipe passes through the installation plate 1 and is through-connected with the folding bag 1, and the ventilation pipe is a foldable structure.

[0011] As a preferred embodiment of the present invention, a push rod is installed on the outer side wall of the movable frame, and a plurality of groups of cleaning rods for moving the ginkgo leaves are installed on the side wall of the push rod.

[0012] Furthermore, the driving assembly includes a first hydraulic rod, which is provided with two groups and is symmetrically arranged on the upper wall of the first support plate with the connecting frame as the symmetry axis. The movable ends of the first hydraulic rods are both equipped with lifting seats, and a second support plate is installed on the upper wall of the lifting seat. The second support plate is respectively connected to the two ends of the connecting frame on the first connecting assembly. A mounting seat is provided on the side wall of the lifting seat close to the winding roller, and a motor is fixed on the mounting seat. The output shaft end of the motor is connected to the center position of the winding roller on the first connecting assembly.

[0013] Preferably, a telescopic rod is installed between the winding roller on the first connecting component and the winding roller on the second connecting component, and the rod and the sleeve in the telescopic rod are movably connected through a clamp and a clamping groove. When the winding roller on the first connecting component rotates, the winding roller on the second connecting component can be driven to rotate through the telescopic rod. When the rotation stops, the second hydraulic rod can work to push the second connecting component away from the first connecting component, and the telescopic rod is gradually stretched.

[0014] Wherein, the bottom wall of the storage box is a mesh structure, which is convenient for discharging impurities.

[0015] After adopting the above structure, the beneficial effects of the present invention are as follows:

The first connecting component fixes the ends of the ginkgo branches, and the second connecting component picks the ginkgo leaves on the ginkgo branches clamped by the first connecting component. During the picking process, the upper pressing plate and the lower pressing plate on the second connecting component only pick the ginkgo leaves at the upper and lower ends of the ginkgo branches, and some of the ginkgo leaves on the branches can be retained, improving the survival rate of the ginkgo trees. Moreover, the upper pressing plate and the lower pressing plate can simultaneously harvest the ginkgo leaves on a batch of ginkgo branches, improving the picking efficiency.

[0017] (2) When the second mounting plate moves towards the first connecting component along with the second connecting component, the first folding bladder is compressed, and the gas inside the first folding bladder enters the second folding bladder. The second folding bladder bulges to drive the moving frame. When the moving frame moves, it stirs the ginkgo leaves in the storage box to shake off the impurities in the ginkgo leaves.

[0018] (3) When the second mounting plate moves away from the first connecting component along with the second connecting component, the first folding bladder is stretched, and the spring drives the moving frame to move in the reverse direction. The gas in the second folding bladder enters the first folding bladder, and the moving frame drives the ginkgo leaves that have fallen into the storage box again to shake off the impurities in the ginkgo leaves.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or sequence between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0033] Such as Figures 1 - 10As shown in the figure, a ginkgo leaf harvesting mechanism includes a harvesting vehicle 1 for movement. A first support plate 2 is installed on the upper wall of the harvesting vehicle 1. A driving component 3 is installed on the upper wall of the first support plate 2. A first connection component 4 is installed at the upper end of the driving component 3. A second hydraulic rod 5 is installed on the side wall of the first connection component 4. A second connection component 6 is installed at the movable end of the second hydraulic rod 5. A storage and cleaning component 7 is also installed on the harvesting vehicle 1 to store and clean the harvested ginkgo leaves.

[0034] Both the first connection component 4 and the second connection component 6 are made of lightweight materials and have the same structure. Only one of them will be introduced here. The first connection component 4 includes a connection frame 8. The connection frame 8 is arranged at the upper end of the driving component 3. The fixed end of the second hydraulic rod 5 is arranged on the side wall of the connection frame 8 on the first connection component 4. The connection frame 8 on the second connection component 6 is connected to the movable end of the second hydraulic rod 5. A cavity is provided inside the connection frame 8. A plurality of guiding rollers 9 for adjusting the direction are movably installed inside the cavity. A connecting plate 10 is installed on the side wall of one end of the connection frame 8. A winding roller 11 is movably installed on the connecting plate 10. A connecting rope 12 is wound around the winding roller 11. The other end of the connecting rope 12 is provided with a plurality of dragging ropes 13 for driving. The number of the dragging ropes 13 is the same as the number of the guiding rollers 9, and the dragging ropes 13 are respectively movably arranged on the guiding rollers 9. The lower ends of the dragging ropes 13 movably penetrate through the bottom wall of the connection frame 8 and are arranged at the lower end of the connection frame 8.

[0035] Fixing plates 14 are respectively installed at both ends of the bottom wall of the connection frame 8. A plurality of upper pressing plates 15 for fixing are evenly installed at equal intervals on the fixing plates 14. Elastic members 16 for protection are installed on the bottom walls of the upper pressing plates 15. The thickness of the elastic member 16 on the first connection component 4 is greater than the thickness of the elastic member 16 on the second connection component 6. The dragging ropes 13 arranged at the lower end of the connection frame 8 sequentially penetrate through the upper pressing plates 15 movably. A plurality of lower pressing plates 17 for fixing are evenly installed at equal intervals on the dragging ropes 13 arranged at the lower end of the connection frame 8. The number of the lower pressing plates 17 is the same as the number of the upper pressing plates 15. The upper pressing plates 15 and the lower pressing plates 17 are placed alternately. The upper walls of the lower pressing plates 17 are all made of elastic materials to facilitate the protection of ginkgo leaves.

[0036] It should be noted that when the winding roller 11 rotates, it drives the connecting rope 12 to rotate and wind. The connecting rope 12 drives the dragging rope 13 to rotate along the guiding roller 9. The dragging rope 13 movably penetrates through the upper pressing plate 15 and then drives the lower pressing plate 17 to move upward. As the lower pressing plate 17 continues to move, multiple groups of ginkgo branches arranged between the lower pressing plate 17 and the upper pressing plate 15 are fixed between the upper pressing plate 15 and the lower pressing plate 17. At this time, the ginkgo branches are respectively clamped in the first connecting assembly 4 and the second connecting assembly 6. The first connecting assembly 4 fixes the ends of the ginkgo branches. Then, the second hydraulic rod 5 works to push the second connecting assembly 6 away from the first connecting assembly 4. The second connecting assembly 6 picks the ginkgo leaves on the ginkgo branches clamped and fixed by the first connecting assembly 4. During the picking process, the second connecting assembly 6 gently bends in the opposite direction of the growth of the ginkgo leaves. At the same time, the upper pressing plate 15 and the lower pressing plate 17 on the second connecting assembly 6 only pick the ginkgo leaves at the upper and lower ends of the ginkgo branches. When harvesting the same branch, some ginkgo leaves on the branch can be retained to improve the survival rate of the ginkgo tree. Moreover, the upper pressing plate 15 and the lower pressing plate 17 can simultaneously harvest the ginkgo leaves on a batch of ginkgo branches, improving the picking efficiency.

[0037] On the upper wall of the connecting frame 8 of the first connecting assembly 4, there is a first mounting plate 18. On the upper wall of the connecting frame 8 of the second connecting assembly 6, there is a second mounting plate 19. The first mounting plate 18 and the second mounting plate 19 are placed opposite to each other. Between the first mounting plate 18 and the second mounting plate 19, there is a first folding bladder 20. The first folding bladder 20, the first mounting plate 18, and the second mounting plate 19 are hermetically connected.

[0038] At the bottom wall of the lowermost lower pressing plate 17 of the second connecting assembly 6, a fixing frame 21 is installed. At the lower end of the fixing frame 21, a flexible storage member 22 is installed. The flexible storage member 22 is of a cavity structure and is connected to the fixing frame 21 in a through manner. On the upper wall of the first support plate 2, there is a storage frame 23. The upper end of the storage frame 23 is connected to the flexible storage member 22 in a through manner. The ginkgo leaves picked by the second connecting assembly 6 fall into the fixing frame 21 and then fall into the storage frame 23 through the flexible storage member 22.

[0039] The storage and cleaning assembly 7 includes a storage box 24. The bottom wall of the storage box 24 is of a mesh structure to facilitate the discharge of impurities. The storage box 24 is arranged on the bottom wall of the first support plate 2. The lower end of the storage frame 23 is connected to the inner space of the storage box 24 in a through manner. The storage and cleaning assembly 7 further includes a moving frame 25. The moving frame 25 is movably arranged in the storage box 24. The bottom wall and the upper wall of the moving frame 25 are connected to the bottom wall and the upper wall of the storage box 24 through ball bearings, which can reduce the friction force. Between the moving frame 25 and the inner side wall of the storage box 24, a second folding bladder 26 and a spring 27 are installed. The spring 27 is arranged inside the second folding bladder 26. The second folding bladder 26, the moving frame 25, and the storage box 24 are hermetically connected.

[0040] An air vent chamber two 28 is provided inside the side wall of the storage box 24 close to the folding bladder two 26. An air vent chamber one 29 is provided inside the first support plate 2. The air vent chamber two 28 is connected to the folding bladder two 26 in a through manner. One end of the air vent chamber one 29 is connected to the upper end of the air vent chamber two 28 in a through manner. A ventilation pipe 30 is further installed on the upper wall of the first support plate 2. The lower end of the ventilation pipe 30 is connected to the air vent chamber one 29 in a through manner. The upper end of the ventilation pipe 30 penetrates through the first mounting plate 18 and is connected to the folding bladder one 20 in a through manner. The ventilation pipe 30 is a foldable structure;

[0041] It should be noted that when the second mounting plate 19 moves towards the first connection component 4 along with the second connection component 6, the folding bladder one 20 is compressed. The gas in the folding bladder one 20 enters the air vent chamber one 29 through the ventilation pipe 30, and enters the air vent chamber two 28 through the air vent chamber one 29. The gas in the air vent chamber two 28 enters the folding bladder two 26, and the folding bladder two 26 bulges to drive the moving frame 25. When the moving frame 25 moves, it stirs the ginkgo leaves in the storage box 24 to shake off the impurities in the ginkgo leaves. At this time, the spring 27 is in a stretched state; when the second mounting plate 19 moves away from the first connection component 4 along with the second connection component 6, the folding bladder one 20 is stretched, and the spring 27 drives the moving frame 25 to move in the reverse direction. The gas in the folding bladder two 26 enters the folding bladder one 20, and the moving frame 25 stirs the ginkgo leaves that have fallen into the storage box 24 again to shake off the impurities in the ginkgo leaves.

[0042] A push rod 31 is installed on the outer side wall of the moving frame 25, and a plurality of cleaning rods 32 for stirring the ginkgo leaves are installed on the side wall of the push rod 31.

[0043] The driving component 3 includes two first hydraulic rods 33, which are symmetrically arranged on the upper wall of the first support plate 2 with the connection frame 8 as the axis of symmetry. Lifting seats 34 are installed at the movable ends of the first hydraulic rods 33. A second support plate 35 is installed on the upper wall of the lifting seats 34. The second support plate 35 is respectively connected to both ends of the connection frame 8 on the first connection component 4. An installation seat 36 is provided on the side wall of the lifting seat 34 close to the winding roller 11. A motor 37 is fixed on the installation seat 36. The output shaft end of the motor 37 is connected to the central position of the winding roller 11 on the first connection component 4; when the motor 37 works, it drives the winding roller 11 on the first connection component 4 to rotate, and the winding roller 11 on the first connection component 4 drives the winding roller 11 on the second connection component 6 to move synchronously through the telescopic rod 38.

[0044] It should be noted that a telescopic rod 38 is installed between the winding roller 11 on the first connecting assembly 4 and the winding roller 11 on the second connecting assembly 6. The rod in the telescopic rod 38 is movably connected to the sleeve through a clamping member and a clamping groove. When the winding roller 11 on the first connecting assembly 4 rotates, it can drive the winding roller 11 on the second connecting assembly 6 to rotate through the telescopic rod 38. After the rotation stops, the second hydraulic rod 5 works to push the second connecting assembly 6 away from the first connecting assembly 4, and at this time the telescopic rod 38 is gradually stretched.

[0045] The specific use is as follows: Initially, the upper wall of the lower pressing plate 17 is placed in contact with the bottom wall of the upper pressing plate 15. The distance from the connecting frame 8 to the upper wall of the first support plate 2 is the shortest, and the distance between the first connecting assembly 4 and the second connecting assembly 6 is the shortest. Move the picking vehicle 1 to the ginkgo tree to be picked, adjust the position of the connecting frame 8 according to the height of the ginkgo tree. The first hydraulic rod 33 works to drive the lifting seat 34 to move upward. The lifting seat 34 drives the second support plate 35 and the connecting frame 8 to move upward. After the height of the connecting frame 8 is adjusted, the motor 37 works to drive the winding roller 11 on the first connecting assembly 4 to rotate in the reverse direction. The winding roller 11 on the first connecting assembly 4 drives the winding roller 11 on the second connecting assembly 6 to move synchronously through the telescopic rod 38. The connecting rope 12 on the winding roller 11 is relaxed. Under the gravity of the lower pressing plate 17, the dragging rope 13 moves downward along the guide roller 9, and the distance between the upper pressing plate 15 and the lower pressing plate 17 increases. Then move the picking vehicle 1 under the ginkgo tree to be picked, and the ginkgo branches to be picked are arranged between the upper pressing plate 15 and the lower pressing plate 17;

[0046] The motor 37 operates to drive the winding roller 11 on the first connection assembly 4 to rotate. When the winding roller 11 on the first connection assembly 4 rotates, it drives the winding roller 11 on the second connection assembly 6 to rotate through the telescopic rod 38. When the winding roller 11 rotates, it drives the connecting rope 12 to rotate and wind. The connecting rope 12 drives the dragging rope 13 to rotate along the guiding roller 9. The dragging rope 13 movably passes through the upper pressing plate 15 and then drives the lower pressing plate 17 to move upward. As the lower pressing plate 17 continues to move, multiple groups of ginkgo branches provided between the lower pressing plate 17 and the upper pressing plate 15 are fixed between the upper pressing plate 15 and the lower pressing plate 17. At this time, the ginkgo branches are respectively clamped within the first connection assembly 4 and the second connection assembly 6. The first connection assembly 4 fixes the ends of the ginkgo branches. Then, the second hydraulic rod 5 operates to push the second connection assembly 6 away from the first connection assembly 4. The second connection assembly 6 picks the ginkgo leaves on the ginkgo branches clamped and fixed by the first connection assembly 4. During the picking process, the second connection assembly 6 gently bends in the opposite direction of the growth of the ginkgo leaves. At the same time, the upper pressing plate 15 and the lower pressing plate 17 on the second connection assembly 6 only pick the ginkgo leaves at the upper and lower ends of the ginkgo branches. When harvesting the same branch, some ginkgo leaves on the branch can be retained to improve the survival rate of the ginkgo tree. Moreover, the upper pressing plate 15 and the lower pressing plate 17 can simultaneously harvest the ginkgo leaves on a batch of ginkgo branches, improving the picking efficiency.

[0047] The ginkgo leaves picked by the second connection assembly 6 fall into the fixed frame 21 and then fall into the storage frame 23 through the flexible storage member 22;

[0048] When the second mounting plate 19 moves in the direction close to the first connection assembly 4 along with the second connection assembly 6, the first folding bladder 20 is compressed. The gas in the first folding bladder 20 enters the first ventilation cavity 29 through the ventilation pipe 30, and then enters the second ventilation cavity 28 through the first ventilation cavity 29. The gas in the second ventilation cavity 28 enters the second folding bladder 26, and the second folding bladder 26 bulges to drive the moving frame 25. When the moving frame 25 moves, it stirs the ginkgo leaves in the storage box 24 to shake off the impurities in the ginkgo leaves. At this time, the spring 27 is in a stretched state; when the second mounting plate 19 moves in the direction away from the first connection assembly 4 along with the second connection assembly 6, the first folding bladder 20 is stretched, and the spring 27 drives the moving frame 25 to move in the reverse direction. The gas in the second folding bladder 26 enters the first folding bladder 20, and the moving frame 25 stirs the ginkgo leaves that have fallen into the storage box 24 again to shake off the impurities in the ginkgo leaves. The impurities are discharged from the grid on the bottom wall of the storage box 24.

[0049] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the present invention, design similar structural methods and embodiments to this technical solution without creative efforts, they should all fall within the protection scope of the present invention.
