Description

Technical Field

[0001] This utility model relates to a ginkgo leaf harvesting device, specifically a ginkgo leaf harvesting platform and a ginkgo leaf harvesting machine. Background Technology

[0002] Ginkgo leaves have medicinal value, which is why ginkgo trees are cultivated as an economic crop. To facilitate the harvesting of ginkgo leaves, the technique of dwarfing and dense planting of ginkgo trees is adopted. However, there is currently a lack of special machinery and equipment for harvesting ginkgo leaves, and manual harvesting is still the main method, resulting in low harvesting efficiency and high labor costs.

[0003] Therefore, there is an urgent need for a mechanized harvesting device for ginkgo leaves to improve harvesting efficiency and reduce labor costs. Utility Model Content

[0004] The purpose of this utility model is to provide a ginkgo leaf harvesting platform and a ginkgo leaf harvesting machine to solve the problems of low efficiency and high labor costs in the current manual harvesting of ginkgo leaves.

[0005] This utility model is implemented as follows: A ginkgo leaf harvesting platform includes a harvesting platform frame, on which at least one picking mechanism is provided. The picking mechanism includes two sets of picking rollers arranged symmetrically on the left and right, with at least one picking roller in each set. The two sets of picking rollers are close to each other to form a plant channel. Conveyors are respectively provided on the lower sides of the picking mechanism. A cover is provided on the harvesting platform, and plant inlets and plant outlets corresponding to the plant channel are respectively opened at the front and rear ends of the cover.

[0006] As a further improvement to the ginkgo leaf harvesting platform of this utility model, both the picking roller and the conveyor are inclined forward and backward, and the height of the picking roller and the conveyor gradually increases from front to back.

[0007] As a further improvement to the ginkgo leaf harvesting platform of this utility model, there are several harvesting mechanisms arranged side by side.

[0008] As a further improvement to the ginkgo leaf harvesting platform of this utility model, a receiving bin is provided at the rear end of the harvesting platform frame, and a conveying auger is provided in the receiving bin, with the ends of all the conveyors extending into the receiving bin.

[0009] As a further improvement to the ginkgo leaf harvesting platform of this utility model, the harvesting roller includes a roller shaft and a combing brush disposed on the roller shaft.

[0010] As a further improvement to the ginkgo leaf harvesting platform of this utility model, a divider is provided in front of the harvesting platform frame, and the divider is located on both sides of the plant inlet.

[0011] As a further improvement to the ginkgo leaf harvesting platform of this utility model, branch-gathering rods are respectively provided on both sides above the plant channel. The length direction of the branch-gathering rods is consistent with the axial direction of the harvesting roller. The front and rear ends of the branch-gathering rods are respectively connected to the harvesting platform frame through elastic adjustment mechanisms.

[0012] As a further improvement to the ginkgo leaf harvesting platform of this utility model, the elastic adjustment mechanism includes a connector, a telescopic rod, a sleeve, a spring, and an anti-detachment nut. The end of the branch-gathering rod is fixedly connected to the connector, the sleeve is fixedly installed on the harvesting platform frame, one end of the telescopic rod is a hinge joint, the other end of the telescopic rod passes through the sleeve and is threaded to the anti-detachment nut at the end, the connector is hinged to the hinge joint, the spring is sleeved on the telescopic rod, and the two ends of the spring are in contact with the hinge joint and the sleeve, respectively.

[0013] This utility model also discloses a ginkgo leaf harvester, including a vehicle body, a lifting device, a material box, and a ginkgo leaf harvesting platform; the ginkgo leaf harvesting platform is located at the front end of the vehicle body, and the lifting device is located between the material box and the ginkgo leaf harvesting platform, for conveying the ginkgo leaves harvested by the ginkgo leaf harvesting platform to the material box.

[0014] As a further improvement to the ginkgo leaf harvester of this utility model, the lifting device includes a first lifter and a second lifter.

[0015] The ginkgo leaf harvesting platform of this utility model has a picking mechanism set inside the cover. Two sets of picking rollers arranged symmetrically on the left and right form a plant channel. After the ginkgo tree enters the plant channel, the ginkgo leaves are picked by the picking rollers on both sides. The picked ginkgo leaves fall onto the conveyors on both sides below the picking mechanism and are transported backward by the conveyors, thereby realizing the automatic picking operation of ginkgo leaves.

[0016] The picking roller rotates in a specific direction, and the combing brush on the roller beats the ginkgo leaves on the ginkgo tree to make them fall off. The combing brush can minimize damage to the ginkgo tree branches or leaves and ensure the quality of the picked ginkgo leaves.

[0017] The picking roller and the conveyor gradually increase in height from front to back, so that the overall height of the picking mechanism is greater than the height of the dwarf ginkgo tree, and the ginkgo tree can be picked as a whole when it passes through the picking mechanism.

[0018] After the ginkgo tree enters the plant channel, its upper branches are gathered together by the branch-gathering rods on both sides. The gathered branches are more easily inserted between the harvesting rollers, facilitating the harvesting of ginkgo leaves. At the same time, the front and rear ends of the branch-gathering rods are connected to the harvesting platform through elastic adjustment mechanisms, which prevents the branches from breaking due to excessive deformation during the gathering process, thus protecting the branches.

[0019] The ginkgo leaf harvester of this utility model is equipped with the aforementioned ginkgo leaf harvesting platform, and automatically transports the harvested ginkgo leaves into the material box through an elevator, thereby realizing the automatic harvesting operation of ginkgo leaves.

[0020] This invention can greatly improve the harvesting efficiency of ginkgo leaves and reduce labor costs. It is applicable to the harvesting of ginkgo leaves using the dwarfing and dense planting technology of ginkgo trees. Attached Figure Description

[0029] Example 1

[0030] like Figure 1 , Figure 2 As shown, this embodiment is a ginkgo leaf harvesting platform 2, which mainly includes a harvesting platform frame 2-1, a cover 2-4, a picking mechanism, a receiving bin 2-8, an auger, and a conveying device.

[0031] The cover 2-4, the picking mechanism, the receiving bin 2-8, the auger, and the conveying device are installed on the harvesting platform 2-1. The harvesting platform 2-1 can be a frame structure formed by connecting square tubes. The cover 2-4 is made of steel plate, which covers the harvesting platform 2-1 to form the cover 2-4 structure. The cover 2-4 is mainly used to accommodate the picking mechanism.

[0032] The system includes at least one harvesting mechanism, and each harvesting mechanism includes two sets of harvesting rollers 2-2, one on the left and one on the right. The roller shafts 2-2-1 of the harvesting rollers 2-2 are in the front-to-back direction. Each set contains at least one harvesting roller 2-2. In this embodiment, each set contains two harvesting rollers 2-2. The two harvesting rollers 2-2 in each set are arranged side by side, one above the other, and the two sets of harvesting rollers 2-2 are arranged symmetrically to each other, so that a plant passage is formed between the two sets of harvesting rollers 2-2 for the plant to pass through. In order to ensure the harvesting effect, the two sets of harvesting rollers 2-2 are close to each other, so that the harvesting rollers 2-2 are in full contact with the plant when the plant passes through.

[0033] The picking roller 2-2 includes a roller shaft 2-2-1 and a combing brush 2-2-2 mounted on the roller shaft 2-2-1. The combing brush 2-2-2 is made of flexible material and is evenly distributed on the roller shaft 2-2-1, perpendicular to the axial direction of the roller shaft 2-2-1. The high-speed rotation of the roller shaft 2-2-1 causes the combing brush 2-2-2 to pluck ginkgo leaves from the branches, while minimizing damage to the branches and leaves.

[0034] Conveyors 2-3 are installed on both sides below each picking mechanism, and the conveying direction of conveyors 2-3 is back and forth.

[0035] Plant entrance 2-4-1 and plant exit corresponding to the plant passage are respectively opened at the front and rear ends of the cover 2-4. The ginkgo tree plant enters the cover 2-4 through the plant entrance 2-4-1, passes through the harvesting mechanism, and leaves the cover 2-4 through the plant exit.

[0036] In the two sets of picking rollers 2-2, the left picking roller 2-2 rotates counterclockwise and the right picking roller 2-2 rotates clockwise, combing the ginkgo leaves upward to both sides. Due to the presence of the cover 2-4, the ginkgo leaves picked during the picking process will remain inside the cover 2-4 and fall onto the conveyors 2-3 on both sides, and be conveyed backward by the conveyors 2-3.

[0037] Conveyor 2-3 is specifically a belt conveyor mechanism.

[0038] Both the picking roller 2-2 and the conveyor 2-3 are inclined forward and backward, and their height gradually increases from front to back. The inclined picking roller 2-2 can gradually comb the ginkgo tree from bottom to top.

[0039] In this embodiment, there are two harvesting mechanisms, which are arranged side by side within the cover 2-4, allowing for simultaneous harvesting of two rows of ginkgo trees.

[0040] like Figure 1 , Figure 3 As shown, a receiving bin 2-8 is located at the rear end of the harvesting platform 2-1. A conveying auger 2-9 is installed inside the receiving bin 2-8. Several feed inlets 2-11 are provided on the receiving bin 2-8. The ends of all conveyors 2-3 extend into the receiving bin 2-8 through their respective feed inlets 2-11, conveying the ginkgo leaves harvested by the harvesting mechanism backward into the receiving bin 2-8. A discharge outlet 2-12 is located at the bottom center of the receiving bin 2-8. The left and right sections of the conveying auger 2-9 rotate in opposite directions, allowing the ginkgo leaves inside the receiving bin 2-8 to be conveyed towards the center and discharged through the discharge outlet 2-12.

[0041] The conveying auger 2-9 can specifically be a shaftless spiral auger.

[0042] To facilitate the delivery of ginkgo trees into the plant channel, a divider 2-7 is installed in front of the harvesting platform 2-1. The divider 2-7 is located on both sides of the plant entrance 2-4-1. The divider 2-7 can separate plants from different rows to prevent ginkgo trees from interfering with each other.

[0043] Branch-gathering rods 2-5 are installed on both sides above the plant channel. The length direction of the branch-gathering rods 2-5 is consistent with the axis of the harvesting rollers 2-2, and the length of the branch-gathering rods 2-5 is basically the same as the length of the harvesting rollers 2-2. The two branch-gathering rods 2-5 are located above the harvesting rollers 2-2, and the distance between the two branch-gathering rods 2-5 is less than the distance between the roller shafts 2-2-1 of the two harvesting rollers 2-2 on the left and right sides of the plant channel. The front and rear ends of the branch-gathering rods 2-5 are connected to the harvesting platform 2-1 through horizontally set elastic adjustment mechanisms 2-6. The elastic adjustment mechanisms 2-6 make the two branch-gathering rods 2-5 tend to move closer to each other after being spread apart by the ginkgo tree, thereby gathering the branches on both sides of the ginkgo tree in the middle. The gathered ginkgo tree is easier to harvest later.

[0044] A horizontal guide roller 2-10 is provided at the upper front of the plant inlet 2-4-1. For ginkgo trees that are higher than the plant inlet 2-4-1, the upper part of the ginkgo tree is bent by the obstruction of the guide roller 2-10 so that it can pass through the plant inlet 2-4-1, and prevent the plant from being damaged by contact and friction with the cover 2-4.

[0045] Two rows of sealing brushes are installed at the plant entrance 2-4-1. The two rows of sealing brushes can seal the plant entrance 2-4-1 to prevent the ginkgo leaves picked from inside the cover 2-4 from escaping. At the same time, the plant can easily pass through the sealing brushes.

[0046] Among them, such as Figure 4 As shown, the elastic adjustment mechanism 2-6 includes a connector 2-6-1, a telescopic rod 2-6-3, a sleeve 2-6-5, a spring 2-6-4, and an anti-detachment nut 2-6-6. The sleeve 2-6-5 is directly or indirectly fixed to the harvesting platform 2-1. One end of the telescopic rod 2-6-3 is a hinge joint 2-6-2, and the other end of the telescopic rod 2-6-3 passes through the sleeve 2-6-5 and is threadedly connected to the anti-detachment nut 2-6-6 at the end. The spring 2-6-4 is sleeved on the telescopic rod 2-6-3, and both ends of the spring 2-6-4 are in contact with the hinge joint 2-6-2 and the sleeve 2-6-5, respectively. The connector 2-6-1 is hinged to the hinge joint 2-6-2. The end of the branch-gathering rod 2-5 is fixedly connected to the connector 2-6-1 by means of insertion, welding, or other connection methods. When the branch-gathering rod 2-5 is opened, the telescopic rod 2-6-3 moves outward and compresses the spring 2-6-4. When no plant passes through, the branch-gathering rod 2-5 returns to its original position under the action of the spring 2-6-4.

[0047] Example 2

[0048] like Figure 5As shown, this embodiment is a ginkgo leaf harvester, including a vehicle body, a lifting device, a material bin 5, and a ginkgo leaf harvesting platform 2. The vehicle body, lifting device, and material bin 5 are all existing technologies. The ginkgo leaf harvesting platform 2 is located at the front end of the vehicle body. The specific structure of the ginkgo leaf harvesting platform 2 is detailed in Embodiment 1. The lifting device is located between the material bin 5 and the ginkgo leaf harvesting platform 2, and is used to transport the ginkgo leaves harvested by the ginkgo leaf harvesting platform 2 to the material bin 5.

[0049] The lifting device includes a first lifter 3 and a second lifter 4. The front end of the first lifter 3 is located below the discharge port 2-12 of the receiving hopper 2-8.

[0050] Example 3

[0051] This embodiment is a method for harvesting ginkgo leaves, based on the ginkgo leaf harvester in Embodiment 2. It is suitable for dwarf and densely planted ginkgo trees. The technology of dwarf and densely planted ginkgo trees is existing technology and will not be described in detail here. Dwarf and densely planted ginkgo trees are shorter and have a higher plant density, which facilitates mechanized harvesting. This method includes the following steps.

[0052] a. Start the ginkgo leaf harvester. All parts start operating. Adjust the position of the vehicle body 1 so that the plant inlet 2-4-1 on the cover 2-4 corresponds to the ginkgo tree. The ginkgo leaf harvesting platform 2 moves along the row of ginkgo trees with the vehicle body 1. During the movement of the vehicle body 1, ginkgo trees in different rows are separated by the separator 2-7. Ginkgo trees in the same row enter the plant channel inside the cover 2-4 through the plant inlet 2-4-1 in turn. The harvesting mechanism inside the cover 2-4 then performs the ginkgo leaf harvesting operation in turn.

[0053] b. For ginkgo trees that are gradually moving backward relative to the ginkgo leaf harvester within the plant passage, the branch-gathering rods 2-5 on both sides gradually gather the branches on both sides of the ginkgo tree upward from the middle and lower part of the ginkgo tree.

[0054] The trunk of the ginkgo tree has branches that extend in different directions from the middle upwards. However, because the picking rollers 2-2 on the left and right sides are close to each other, when the ginkgo tree passes directly through the plant passage, the branches on the left and right sides of the ginkgo tree will interfere with the picking rollers 2-2 on the left and right sides, affecting the picking effect of the picking rollers 2-2 and easily causing the ginkgo leaves and branches to break and be damaged.

[0055] Because the branch-gathering rod 2-5 is tilted backward and upward, when the ginkgo tree passes by, the branch-gathering rod 2-5 gradually gathers the branches on the left and right sides of the ginkgo tree upward. After being gathered, the thickness of the ginkgo tree branches and leaves in the left and right direction is small. The ginkgo tree branches and leaves only come into contact with the combing brush 2-2-2 on the picking roller 2-2. The combing brush 2-2-2 is flexible. At the same time, because the branches are gathered upward, the picking roller 2-2 also combs upward from the lower right. The combing direction is consistent with the length direction of the branches, thereby avoiding damage to the branches.

[0056] When the branches of the ginkgo tree are relatively stiff, forcibly gathering the branches with the branch-gathering rod 2-5 can easily break the branches. Therefore, the two ends of the branch-gathering rod 2-5 are further installed on the harvesting platform 2-1 through the elastic adjustment mechanism 2-6, so that the distance between the two branch-gathering rods 2-5 can be adjusted adaptively to avoid damage to the branches.

[0057] c. The picking roller 2-2 on the left side of the plant channel rotates counterclockwise, and the picking roller 2-2 on the right side of the plant channel rotates clockwise. The combing brush 2-2-2 on the picking roller 2-2 combs the branches and leaves of the ginkgo tree and strikes the ginkgo leaves from the branches in an upward direction.

[0058] The combing force of the combing brush 2-2-2 is adjusted by the rotation speed of the picking roller 2-2.

[0059] d. The ginkgo leaves that are combed down move to the left and right sides with the picking roller 2-2, and under the restriction of the cover 2-4, the ginkgo leaves fall and gather on the conveyors 2-3 on the left and right sides.

[0060] e. The ginkgo leaves are output from inside the cover 2-4 by the conveyor 2-3.

[0061] The conveyor 2-3 runs in a front-to-back direction, outputting ginkgo leaves from the bottom of the left and right sides of the cover 2-4 to the outside of the cover 2-4.

[0062] Furthermore, there are two harvesting mechanisms arranged side by side, allowing the ginkgo leaf harvester to harvest two rows of ginkgo trees simultaneously. A receiving bin 2-8 is located at the rear end of the harvesting platform 2-1, and a conveying auger 2-9 is installed inside the receiving bin 2-8. The ends of all conveyors 2-3 extend into the receiving bin 2-8, and a discharge port 2-12 is located at the bottom center of the receiving bin 2-8. The left and right sections of the conveying auger 2-9 rotate in opposite directions. The conveying auger 2-9 transports the ginkgo leaves from the receiving bin 2-8 towards the center and outputs them through the discharge port 2-12 to the elevator, which then transports the ginkgo leaves to the material box 5 on the vehicle body 1.

[0063] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
