Description

Technical Field

[0001] The present invention relates to the technical field of ginkgo leaf picking equipment, and in particular to a ginkgo leaf non-destructive picking device. Background Art

[0002] Ginkgo leaves are the dried leaves of Ginkgo biloba, a plant of the Ginkgoaceae family. They are harvested when the leaves mature in autumn and dried in time. Ginkgo leaves have good medicinal value and have good therapeutic effects on many diseases. In recent years, the planting area of ​​ginkgo leaves in my country has been expanding year by year. Studies have found that the content of active ingredients in ginkgo leaves has an age effect, that is, as the age of ginkgo trees increases, the content of active ingredients in the leaves will decrease. Now the cultivation model of most ginkgo leaf-picking gardens is mostly 1-6 year old seedlings for harvesting leaves, and the grown-up ginkgo seedlings are produced as landscaping seedlings.

[0003] In the prior art, ginkgo leaf picking is generally divided into manual picking or mechanical picking. Due to the low efficiency of manual picking and the high safety risks, mechanized picking has gradually replaced manual picking. Mechanized picking mainly involves placing the ginkgo leaves on the branches in a machine casing, and then using the internal blade to approach the petiole of the ginkgo leaves to achieve picking by cutting or shearing. However, due to the different maturity and uneven distribution of ginkgo leaves on the ginkgo tree branches, a large number of immature ginkgo leaves will be damaged during the picking process, and even the bark will be damaged, affecting the normal growth of the ginkgo tree and secondary picking. Summary of the Invention

[0004] Technical problems solved

The bracket is rotatably connected to a cutting frame on the side away from the connecting rod. The cutting frame is in the shape of a "J", and a steel wire rope is fixedly connected to the middle of the cutting frame.

[0015] Furthermore, a rod sleeve is rotatably connected to the outer circumference of a cutting frame close to one side of the movable frame, and the outer circumference of the cutting frame is connected to the inner wall of the rod sleeve through a torsion spring, and the end of the rod sleeve away from the cutting frame is fixedly connected to the movable frame.

[0016] Furthermore, the inner walls of the first annular block and the second annular block are respectively fixedly connected with a gear ring, and the movable frame is rotatably connected with a gear meshing with the gear ring.

[0017] Furthermore, the locking piece includes a built-in cavity, which is opened on the side walls of the first annular block and the second annular block.

At the same time, when the first annular block and the second annular block are closed to form complete circular rings, the pin in the locking member cooperates with the card slot and the fixing block to achieve a more stable connection between the joint surfaces of the two gear rings, avoiding the gear from being subjected to uneven force due to the unstable joint surface connection when meshing with the gear ring, accelerating the wear of the gear and shortening its service life. In addition, in conjunction with the first magnet and the second magnet, the limit between the gear rings can be easily released, making it convenient to open the arc-shaped plate for the next picking.

[0048] An inner wall of the arc-shaped plate 31 on a side away from the elastic tube is fixedly connected to an abutting plate 36 via an elastic member.

[0049] refer to Figures 1-9 Mechanized picking mainly involves placing the ginkgo leaves on the branches inside a machine casing, and then using the internal blade to approach the petiole of the ginkgo leaves to achieve picking by cutting or snipping. However, due to the different maturity levels and uneven distribution of ginkgo leaves on the branches, a large number of immature ginkgo leaves will be damaged during the picking process, and even the bark will be damaged, affecting the normal growth of the ginkgo tree and the secondary picking;

[0050] In order to overcome the above-mentioned defects, the present invention designs a ginkgo leaf non-destructive picking device.

[0051] Before picking ginkgo leaves:

[0052] In the initial state, the staff installs the storage tube 21 on the connecting tube 22 using threads, and cooperates with the bracket 343 on the connecting frame 1 to connect the equipment to an external mobile device (the external mobile device is preferably a manipulator here, which can freely adjust the use angle of the equipment). When the equipment moves to the vicinity of the ginkgo tree trunk to be picked, the driving part (the driving part includes an electric push rod, a hydraulic rod, etc., and the electric push rod is preferably used here) will open the two arc plates 31, so that the front end of the arc plate 31 will open (because the arc plate 31 is connected to the inner wall of the elastic tube through a rotating shaft, the arc plate 31 rotates along the rotating shaft with the cooperation of the driving part, and the elastic tube can be made of flexible material, and a rubber tube can be used here. When the arc plate 31 opens, the elastic tube is deformed to avoid excessive gap between the arc plate 31 and the connecting tube 22 during the opening process, causing the ginkgo leaves to fall from the gap). Then the external mobile device moves the opened arc plate 31 close to the root of the ginkgo tree trunk, and the driving part can close the arc plate 31 until the conical space formed by the two arc plates 31 completely wraps the ginkgo tree trunk. The arc plate 31 is installed with an abutment plate 36 using an elastic member. The elastic member can be made of flexible materials, elastic plates, etc., and a hollow elastic plate is preferably used here. In addition, a flexible material such as sponge or rubber block is installed on the surface of the abutment plate 36, and sponge is preferably used here. When the two arc plates 31 are closed, the elastic member cooperates with the sponge on the abutment plate 36 to provide a certain buffer to the ginkgo tree trunk to avoid damage to its epidermis.

[0053] Locking process:

[0054] As the arc plate 31 closes, the two first annular blocks 32 and the two second annular blocks 33 can form a complete circular ring with two overlapping central axes, and the diameter of the circular ring formed by the first annular block 32 is larger than the circular ring formed by the second annular block 33 (when the circular ring is not closed, all components in the locking member 35 are inside the built-in cavity 351. When the circular ring is closed, the components in the locking member 35 will extend out of the built-in cavity 351 for locking, so there will be no interference and affect the closure of the circular ring). At this time, the movable rod 353 will move under the action of the first magnet 357 (the first magnet 357 is an electromagnet, and an electromagnet is provided on the side where the movable rod 353 and the inner wall of the built-in cavity 351 are close to each other. By changing the direction of the current in the electromagnet, the repulsion or attraction between the electromagnets can be completed, thereby realizing the movement of the movable rod 353 in the built-in cavity 351). When the fixing block 355 on the movable rod 353 enters the other built-in cavity 351, since the fixing block 355 is tapered, the tapered surface of the fixing block 355 will squeeze the bayonet 352 (the bayonet 352 is chamfered), so that the bayonet 352 enters the installation cavity, and the return spring is compressed. When the bayonet 352 completes its movement along the tapered surface of the fixing block 355, the return spring will reset the bayonet 352, and the bayonet 352 will move to the flat position of the fixing block 355 (the flat surface on the bayonet 352 will fit with the flat surface of the fixing block 355, thereby forming a Limit), at the same time, the pin 352 will be inserted into the slot 356 on the movable rod 353, which can realize the limiting fixation between the two first annular blocks 32 and the two second annular blocks 33, ensuring that the circular connection formed between the two first annular blocks 32 and the two second annular blocks 33 is more stable, thereby helping to improve the overall structural stability of the ring gear 347, and avoiding that when the gear 348 and the complete ring gear 347 are engaged with each other, due to the unstable connection of the ring gear 347, the gear 348 is subjected to uneven force when engaged, which accelerates the wear of the gear 348 and shortens its service life.

[0055] When the two gear rings 347 need to be separated, at this time, the second magnet 359 on the support plate (the second magnet 359 is an electromagnet design) will push the movable block 354 to move along the movable rod 353. At this time, the plane of the movable block 354 will contact the inclined surface of the latch 352. As the movable block 354 continues to move, the latch 352 will break away from the slot 356 and enter the installation cavity. When the two contact surfaces of the movable block 354 and the fixed block 355 coincide with each other, the latch 352 is completely inserted into the installation cavity. At this time, the first magnet 357 will push the movable rod 353 moves into the built-in cavity 351 again (a positioning block is provided on the inner wall of the built-in cavity 351 on one side of the movable rod 353, and a positioning groove is provided on the outer surface of the circumference of the movable rod 353. When the movable rod 353 moves in the built-in cavity 351, the positioning block will move along the positioning groove, which is conducive to the stable movement of the movable rod 353 in the built-in cavity 351), so that the pin 352 and the fixed block 355 are separated from each other, and the limit between the two first annular blocks 32 and the two second annular blocks 33 is released, and the driving part can open the arc plate 31.

[0056] Ginkgo leaf picking process:

[0057] When the two arc-shaped plates 31 completely wrap the ginkgo tree trunk, the gear 348 rotates (a driving member can be provided on the movable frame 341 to control the rotation of the gear 348, and a stepping motor is preferably used here). Since the gear 348 and the ring gear 347 are engaged with each other, the movable frame 341 will move at a uniform speed along the central axis in the conical space formed by the arc-shaped plates 31 along the guide grooves on the first annular block 32 and the second annular block 33 (as the ginkgo leaves at the branch position will grow more vigorously during the growth process of the ginkgo branches and leaves, the two arc-shaped plates 31 can form a conical space, the space near the ginkgo tree trunk is small, and the space at the branch position is large. The conical space formed by the arc-shaped plates 31 can conform to the growth law of ginkgo leaves). The curved plate 31 fixes the root of the branch so that the central axis of the branch can coincide with the central axis of the conical space formed by the curved plate 31. At this time, the cutting frame 344 can rotate along the central axis of the conical space during the movement (the cutting frames 344 and the movable frame 341 at both ends are connected by rod sleeves 346 and torsion springs. When the wire rope 345 is hung on the tree branch, the torsion spring will buffer it to a corresponding degree. After the wire rope 345 is separated from the tree branch, the torsion spring can reset the cutting frame 344 to avoid damage to the device and affect the normal picking of ginkgo leaves), so that the wire rope 345 can cut its rotation radius The steel wire rope 345 rotates and suddenly contacts the petiole of the ginkgo leaf, and its kinetic energy is quickly converted into impact force, which directly acts on the petiole. At the same time, due to the slender shape of the steel wire rope 345, it also generates shear force on the petiole. These two forces work together to squeeze, stretch and tear the petiole, thereby completing the cutting of the ginkgo leaf. The picked ginkgo leaves will fall into the conical space formed by the arc plate 31 (since the size of mature ginkgo leaves is larger than that of immature ginkgo leaves, the cutting frame 344 rotates according to a certain radius to pick the ginkgo leaves that meet the requirements).

[0058] Ginkgo leaf removal process:

[0059] When the locking member 35 releases the limit between the gear ring 347, the driving unit slightly opens the arc plate 31, so that a certain gap is generated between the arc plate 31 and the branch (the arc plate 31 is opened to form a gap with the branch to facilitate its rotation, so as to avoid the arc plate 31 from opening at an angle too large, causing the ginkgo leaves in the arc plate 31 to fall out of the arc plate 31, resulting in the staff having to collect them again). Then the external mobile device will rotate it to a certain angle so that the ginkgo leaves in the arc plate 31 can fall into one of the arc plates 31, and then the arc plate 31 will be opened again to a certain angle so that the arc plate 31 can After the storage tube 21 is completely separated from the branches, the arc-shaped plate 31 is closed again and placed vertically. At this time, the ginkgo leaves in the arc-shaped plate 31 will enter the storage tube 21 along the connecting tube 22. In addition, a conical cover 23 is provided at the connection between the storage tube 21 and the connecting tube 22 to prevent a large number of ginkgo leaves in the storage tube 21 from entering the conical space formed by the arc-shaped plate 31 and affecting the next use. After the storage tube 21 is disassembled from the connecting tube 22 (the storage tube 21 and the connecting tube 22 are connected by threads, and the staff can unscrew the storage tube 21 from the connecting tube 22), the ginkgo leaves in the storage tube 21 can be collected together.

[0060] In summary, the present invention employs the locking member 35 and the picking member 34 to provide the following advantages:

[0061] Advantage 1: The ginkgo leaves at the top of the ginkgo tree are more lush and mature, while the ginkgo leaves at the back of the branch are sparse and mature. The two curved plates 31 can form a closed conical space, which can conform to the distribution pattern of the ginkgo leaves on the branch. The conical space formed by the curved plates 31 can completely wrap them, making it easy to pick.

[0062] Advantage 2: The arc-shaped plate 31 fixes the rear part of the branch, and can make the central axis of the branch coincide with the central axis of the conical space formed by the arc-shaped plate 31. Since the rotation radius of the wire rope 345 in the conical space remains constant, the wire rope 345 can only cut the ginkgo leaves in the conical space that meet the cutting radius, and will not cut off immature ginkgo leaves, so that they can continue to grow and are convenient for picking next time.

[0063] Advantage three, when the first annular block 32 and the second annular block 33 are closed to form complete circular rings, the latch 352 in the locking member 35 cooperates with the slot 356 and the fixing block 355 to achieve a more stable connection between the joint surfaces of the two gear rings 347, thereby avoiding the gear 348 from being subjected to uneven force due to unstable joint surface connection when meshing with the gear ring 347, accelerating the wear of the gear 348 and shortening its service life. In addition, the unstable joint surface connection of the gear ring 347 will also affect the smoothness of movement of the picking member 34, thereby affecting the picking quality. With the cooperation of the first magnet 357 and the second magnet 359, the limit between the gear rings 347 can be easily released, making it convenient to open the arc plate 31 for the next picking.

[0064] Advantage four: after picking is completed, a certain gap can be slightly opened between the arc plates 31, and then the device can be rotated a certain angle so that the picked ginkgo leaves can fall into one of the arc plates 31, avoiding the two arc plates 31 from being directly opened, causing the ginkgo leaves in the arc plates 31 to fall. In addition, a conical cover 23 is provided between the storage tube 21 and the connecting tube 22, which can realize the unilateral entry of ginkgo leaves into the storage tube 21. When the device is placed vertically or tilted, the ginkgo leaves in the storage tube 21 will not enter the conical space surrounded by the arc plates 31 in large quantities, affecting the normal picking of the removal part 3.
