Description

Technical Field

[0001] The present invention relates to the technical field related to plant collection, and in particular to a collection mechanism for a drone for collecting plant components. Background Art

[0002] As is known, the collection of plant components refers to the process of collecting plant samples from the natural environment, which is usually used in many fields such as scientific research, medicinal plant collection, gardening, ecological monitoring, etc. For the collection of plant components, the roots, stems, leaves, flowers, and fruits of the target plants can be selected. After clarifying the purpose of collection, the appropriate parts of the target plants are selected for collection.

[0003] For example, the patent with announcement number CN115777337A, announcement date March 14, 2023, and titled "A forestry germplasm resource picking device based on drones" includes: a mounting plate, a first support frame and a fixing frame, wherein the mounting plate is mounted on the drone by bolts; an angle adjustment mechanism is arranged below the mounting plate, including a connecting plate, a fixing frame, an adjustment wheel and an adjustment plate; a hydraulic rod is installed on the right side of the first support frame, and a cutting mechanism is arranged at the output end of the hydraulic rod, including a push rod, a first connecting rod, a clamping plate and a cutting knife; the fixing frame is fixed below the first support frame. The forestry germplasm resource picking device based on drones can adjust the angle of the cutting mechanism according to the position of the germplasm resources, ensure the picking effect, avoid the influence of the position of the germplasm resources on the picking, effectively cut the germplasm resources, avoid the germplasm resources being left on the plants, facilitate the replacement of the blade, ensure the cutting effect, and guide the germplasm resources to concentrate for easy collection.

[0004] The shortcoming of the existing technology is that when using a drone to cooperate with a collection mechanism to collect target plant components, there are two ways to arrange the collection mechanism: one is to arrange it directly below the drone body, and when collecting, it is in a straight up and down state. This arrangement is not suitable for some plants with soft branches. Under the action of the airflow driven by the drone, there will be problems of swaying or even tipping over, resulting in the collection mechanism carried by the drone being unable to collect the components of the target plants; the other is to arrange it at a position deviated from directly below the drone body, but the overall center of gravity of the drone and the collection mechanism is offset, so the drone needs to increase power to adjust the flight attitude to ensure normal flight, which will increase energy consumption, especially when collecting plant components in remote areas where manpower is difficult to enter, it will be impossible to fly back. If the collected target plant components are heavy, it may seriously cause the drone to crash. Summary of the invention

[0008] As mentioned above, an elastic shielding cloth is commonly sleeved on the outer walls of the first support plates. The shielding cloth is elastically deformed based on the swinging action of the first support plates.

[0016] As mentioned above, the plurality of first limiting portions and the first elastic portion are separated prior to the plurality of second limiting portions and the second elastic portion being separated.

[0017] The beneficial effect of the present invention is that by setting a shielding mechanism, after the identification unit identifies the target plant, the main body of the drone can fly to a position directly above the target plant, and then the multiple first support plates of the shielding mechanism are deployed under the driving action of the driving member to block the airflow blowing toward the target plant due to the flight of the drone. In this way, when the drone body approaches the target plant, the disturbance of the airflow to the target plant can be significantly reduced, thereby ensuring that the collection unit can smoothly collect the target plant components, and the collection unit and the shielding unit are both arranged directly below the drone body, which can avoid the problem of increased energy consumption due to uneven force caused by the center of gravity shift during the flight of the drone body.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Figure 8 The present invention is further described in detail.

[0030] An embodiment of the present invention provides a collection mechanism for a drone for collecting plant components, including a drone body 1, on which an identification unit 2 and a collection unit are arranged, and the collection unit collects the components of the target plant based on the identification signal of the identification unit 2, and also includes a shielding mechanism 3, the shielding mechanism 3 includes a base 30 and a plurality of first support plates 31 arranged in sequence in the circumferential direction of the base 30, each first support plate 31 is swingably connected to the base 30, and the base 30 is also provided with a driving member 35 for driving the plurality of first support plates 31 to swing synchronously, and the driving member 35 drives the plurality of first support plates 31 to unfold based on the identification signal of the identification unit 2 to block the airflow flowing toward the target plant.

[0031] Specifically, the collection unit in the prior art generally includes a collection tool and a collection mechanism, and the identification unit 2 is such as a video sensor. These are all in the prior art and will not be described in detail. The target plant components to be collected can be flowers, fruits or leaves. When using a drone to cooperate with the collection mechanism to collect the target plant components, there are two ways to arrange the collection mechanism: one is to arrange it directly below the drone body 1. During the collection operation, it is in a straight up and down state. This arrangement method is not suitable for some plants with soft branches. Under the action of the airflow driven by the drone, there will be problems of swaying or even tipping, resulting in the collection mechanism carried by the drone being unable to collect the components of the target plant; the other is to arrange it at a position deviated from the position directly below the drone body 1, but the overall center of gravity of the drone and the collection mechanism is offset, so the drone needs to increase power to adjust the flight attitude to ensure normal flight, which will increase energy consumption, especially when collecting plant components in remote areas where it is difficult for manpower to enter, it will be impossible to fly back. If the collected target plant components are heavy, it may seriously cause the drone to crash.

[0032] In this embodiment, in order to avoid the above problems, the collection unit is arranged at a position directly below the drone body 1, and a shielding mechanism 3 is also arranged at this position. After the identification unit 2 identifies the target plant, the shielding mechanism 3 can block the airflow blowing toward the target plant, that is, the base 30 of the shielding mechanism 3 is fixed to the position directly below the drone body 1 by bolts, and a plurality of first support plates 31 are evenly arranged in the circumferential direction of the base 30, and each first support plate 31 is swingably arranged on the base 30, that is, the swinging mode of the first support plate 31 is from a substantially vertical position to a substantially horizontal position, or in the opposite direction, and the swinging of the plurality of first support plates 31 is uniformly controlled by the driving member 35, such as each first support plate 31 can be arranged with a corresponding driving source 350 with a telescopic function, such as an electric push rod, a cylinder, etc., so that the plurality of first support plates 31 have three states:

[0033] In the first state, the length directions of the plurality of first support plates 31 are substantially parallel to the vertical direction (folded state), and at this time, the vertical wind resistance can be reduced as much as possible during the flight of the drone body 1;

[0034] In the second state, the first supporting plates 31 are driven by the driving member 35 so that their length directions are substantially parallel to the horizontal direction (fully deployed state). At this time, when the drone body 1 approaches the target plant vertically, the first supporting plates 31 can block or reduce the disturbance of the airflow to the target plant.

[0035] In the third state, under the driving action of the driving member 35, the length direction of the multiple first support plates 31 is neither parallel to the vertical direction nor the horizontal direction. For example, the deflection angle of the multiple first support plates 31 from the folded state to the fully expanded state is 90 degrees, then they stop when they are deflected to 45 degrees (semi-expanded state). At this time, the multiple first support plates 31 can act as the landing legs of the drone body 1.

[0036] The beneficial effect of this embodiment is that by setting the shielding mechanism 3, after the identification unit 2 identifies the target plant, the main body 1 of the drone can fly to a position directly above the target plant, and then the multiple first support plates 31 of the shielding mechanism 3 are deployed under the driving action of the driving member 35 to block the airflow blowing toward the target plant due to the flight of the drone. In this way, when the drone main body 1 approaches the target plant, the disturbance of the airflow to the target plant can be significantly reduced, thereby ensuring that the collection unit can smoothly collect the target plant components, and the collection unit and the shielding unit are both arranged directly below the drone main body 1, so that the problem of increased energy consumption due to center of gravity shift caused by uneven force during the flight of the drone main body 1 can be avoided.

[0037] Preferably, an elastic shielding cloth 32 is commonly sleeved on the outer walls of the plurality of first support plates 31 , and the shielding cloth 32 is elastically deformed due to the swinging action of the first support plates 31 , and due to the elastic force of the shielding cloth 32 , the plurality of first support plates 31 tend to be retracted.

[0038] Specifically, it can be seen from the above embodiments that the plurality of first support plates 31 have a folded state and an expanded state. If in the fully expanded state, the plurality of first support plates 31 cooperate with each other to form a substantially complete disc shape, then in the folded state, two adjacent first support plates 31 will inevitably overlap, and if in the folded state, the plurality of first support plates 31 cooperate with each other to form a substantially complete circle with a radial cross section, then in the expanded state, there will inevitably be a gap between two adjacent first support plates 31. In order to reduce the load of the drone, in this embodiment, “in the folded state, the plurality of first support plates 31 cooperate with each other to form a substantially complete circle with a radial cross section” is adopted. The plurality of first support plates 31 are spliced ​​together to form a substantially complete circle in radial cross section, and an elastic shielding cloth 32 is sleeved on the outer walls of the plurality of first support plates 31. When the plurality of first support plates 31 are in a retracted state, the radial cross section of the shielding cloth 32 is also substantially a complete circle. During the unfolding of the plurality of first support plates 31, the shielding cloth 32 is supported by the first support plates 31 and can be elastically deformed. In this way, after the plurality of first support plates 31 are unfolded, the interval between two adjacent first support plates 31 can be shielded by the shielding cloth 32. In this way, after the lightweight UAV body 1 is loaded, the effect of shielding the airflow blowing toward the target plant can be improved.

[0039] Preferably, each of the first support plates 31 is in an arc shape; specifically, the arc-shaped first support plates 31 can better disperse the force of the airflow when blocking the airflow, thereby playing a guiding effect and reducing wind resistance.

[0040] Furthermore, each of the first support plates 31 is provided with a collecting cutter 33 , and when the first support plates 31 are retracted based on the driving action of the driving member 35 , the collecting cutters 33 cut the target plant components together.

[0041] Specifically, in the aforementioned embodiment, for the collection of target plant components, it is necessary to use a collection tool and a collection mechanism separately, which undoubtedly increases the load of the drone body 1. In this embodiment, the collection tool for collecting target plant components is made into a split structure, and the number corresponds to the number of first support plates 31, that is, the collection tool is divided into multiple collection cutters 33, and each first support plate 31 is equipped with a collection cutter 33. During specific operation, when the recognition unit 2 recognizes the target plant, the drone body 1 flies to the position directly above the target plant, and then the multiple first support plates 31 are driven by the driving member 35 to switch from the retracted state to the fully expanded state, and then the drone body 1 moves toward the target plant. When the target plant component is close to the object, when the target plant component is within the wrapped range when the multiple first support plates 31 are folded, the driving member 35 drives the multiple first support plates 31 to switch from the fully expanded state to the folded state. In the process of folding the multiple first support plates 31, the multiple collecting cutters 33 will gradually cut the stems connected to the target plant components until the multiple first support plates 31 are completely folded, and the target plant components will be cut off. The cooperation between the multiple first support plates 31 and the shielding cloth 32, in the folded state, forms a package of multiple target plant components, that is, it plays a collecting role. The advantage of such a setting is that the picking and collection of the target plant components can be completed by utilizing the folding of the multiple first support plates 31.

[0042] Preferably, a second support plate 34 is provided between two adjacent first support plates 31, and the second support plate 34 provides auxiliary support for the shielding cloth 32 between the two adjacent first support plates 31; specifically, since the plurality of first support rods 353 and the shielding cloth 32 are used in conjunction with each other, a better overall structure can be formed in the folded state or the unfolded state, and the first support plate 31 has an arc-shaped structure, which can play a certain role in guiding and reducing wind resistance. However, in the folded state, there is no structure supporting the shielding cloth 32 between the two adjacent first support plates 31, so since the shielding cloth 32 itself Due to the effect of elastic force, the portion between two adjacent first support plates 31 is basically planar in structure, and the surface of the shielding cloth 32 in contact with the first support plate 31 is arc-shaped. The wind resistance caused by such a planar structure is bound to be greater than the wind resistance caused by the arc shape. Therefore, in this embodiment, a second support plate 34 is arranged between two adjacent first support plates 31. The second support plate 34 is in the same arc shape as the first support plate 31, and in the process of unfolding multiple first support plates 31, the multiple second support plates 34 do not follow the unfolding, and they only support the shielding cloth 32 when the multiple first support rods 353 are in a folded state.

[0043] Preferably, the driving member 35 includes a driving source 350 disposed on the base 30, a screw rod 351 is installed at the power output end of the driving source 350, a screw block 352 is screwed on the screw rod 351, a first support rod 353 is fixedly connected to each first support plate 31, and a second support rod 354 is hinged between the screw block 352 and each first support rod 353; specifically, in the aforementioned embodiment, the use of the driving member 35 is to equip each first support plate 31 with a driving source 350 with a telescopic function, such as an electric push rod, a cylinder, etc. In this embodiment, another method is adopted, that is, a driving source 350 is arranged on the base 30, and the driving source 350 is a micro motor, and the power output end of the micro motor A fixed screw rod 351 is provided with a pitch wire block 352. The positive and negative rotation of the screw rod 351 can drive the wire block 352 to reciprocate in a straight line. That is, when the screw rod 351 rotates, it will first give the wire block 352 a circumferential rotational force. A first support rod 353 and a second support rod 354 are connected between the wire block 352 and each first support plate 31. The swinging direction of the first support plate 31 is consistent with the swinging direction of the second support rod 354, but is different from the direction of the circumferential force on the wire block 352. In this way, the circumferential movement of the wire block 352 is restricted. Based on the effect of the threaded fit, the wire block 352 will move in a straight line on the screw rod 351, thereby driving multiple first support plates 31 to be synchronously retracted or unfolded.

[0044] Preferably, it also includes a packaging mechanism 4, which packages the target plants after the target plant components are cut by multiple collecting cutters 33; the packaging mechanism 4 includes a packaging bag 40 arranged at the end of the screw rod 351 away from the driving source 350, and the open end of the packaging bag 40 is provided with a first elastic part 41, and each second support plate 34 is provided with a first limiting part 42; before the target plant components are cut, the open end of the packaging bag 40 is in an open state under the joint action of multiple first limiting parts 42 and the first elastic part 41; after the target plant components are cut, the multiple first limiting parts 42 are separated from the first elastic part 41, and under the action of the rebound force of the first elastic part 41, the open end of the packaging bag 40 is tightened to package the cut target plant components.

[0045] Specifically, it can be seen from the aforementioned embodiments that after collecting the target plant components, when the drone body 1 returns to the take-off and landing point, the multiple first support plates 31 are semi-expanded to serve as landing legs. That is, when the drone is approaching the take-off and landing point, the multiple first support plates 31 need to be driven by the driving member 35 to reach a semi-expanded state, so that the target plant components wrapped therein will fall off, which may damage the target plant components. Therefore, in this embodiment, a packaging mechanism 4 is also provided to package the picked target plant components to prevent the above situation.

[0046] That is, a packing bag 40 is fixedly connected to the end of the screw rod 351 away from the driving source 350. The packing bag 40 is a structure with an open end, and the open end faces the multiple collection cutters 33 in a retracted state. The bottom of the packing bag 40 (the end away from the open end) is plugged into the screw rod 351 through a mounting block and fixed with bolts. The open end of the packing bag 40 is arranged with a first elastic portion 41, such as a rubber band, and a first limiting portion 42 is correspondingly arranged on each second support plate 34. The first limiting portion 42 is a hook-shaped structure. When the multiple first limiting portions 42 jointly open the open end of the packing bag 40, the first elastic portion 41 is at the hook bend of the first limiting portion 42, and the hook bend is a planar structure, and at this time the planar structure is vertical, that is, when the second support plate 34 is inwardly close to the packing bag The bag 40 is at a certain distance, so that the plane at the hook bend is in an inclined state, and the lower end of the inclination is closer to the packing bag 40 than the high end. In this way, the limiting effect of the first limiting portion 42 on the first elastic portion 41 is not enough to resist the rebound force of the first elastic portion 41, and the packing bag 40 will be tightened under the rebound force of the first elastic portion 41. Therefore, in this embodiment, a pressure block 43 is provided on the base 30 through an elastic member, and the pressure block 43 is sleeved on the screw rod 351, but the two are not in contact. A third support rod 44 is hinged between the pressure block 43 and each second support plate 34, and the second support plate 34 is swingably arranged on the base 30. Under the elastic force of the elastic member, when it is in a retracted state, the second support plate 34 can support the shielding cloth 32 externally, wherein The end of the second support rod 354 connected to the first support rod 353 can be rotated and slid, that is, a slide groove 355 is provided at the end of the second support rod 354 connected to the first support rod 353, and the length of the slide groove 355 is greater than the distance required to move when the first limit portion 42 is separated from the first elastic portion 41. The shaft rod 356 provided on the first support rod 353 can slide in the slide groove 355 and can also rotate. When multiple first support plates 31 are needed to be unfolded, one end of the slide groove 355 close to the wire block 352 abuts against the shaft rod 356. When the multiple first support plates 31 are folded, the rebound force of the shielding cloth 32 is utilized. In this way, when the picked target plant components need to be packaged, the driving source 350 first drives the screw rod 351 to rotate, so that the wire block 352 moves to As it moves towards the driving source 350, the wire block 352 will synchronously drive the multiple first support plates 31 to gradually close together. Until they are completely closed and the target plant components are also picked, the driving source 350 continues to drive the screw rod 351 to rotate, and the wire block 352 continues to approach the driving source 350. At this time, the slide groove 355 and the shaft rod 356 move relative to each other, and the multiple first support plates 31 will no longer close together. The wire block 352 will squeeze the pressure block 43 to move, and the pressure block 43 compresses the elastic member and drives the connected second support plate 34 to gradually approach the packaging bag 40 through each third support rod 44. As the plane at the hook bend of the first limiting portion 42 gradually inclines, the first elastic portion 41 breaks away from the first limiting portion 42 and contracts to tighten the bag opening, thereby packaging the target plant components.The packing bag 40 is fixed to the end of the screw rod 351, so when the drone body 1 lands, the first plurality of support plates 31 are half-expanded, and the target plant components will not fall off, thereby achieving the purpose of protecting the target plant components.

[0047] Furthermore, a second elastic portion 45 is arranged on the packing bag 40, and the portion of the packing bag 40 between the first elastic portion 41 and the second elastic portion 45 is used for packing the target plant components, and a second limiting portion 46 is also provided on each second support plate 34; before the target plant components are cut, the packing bag 40 is in an open state under the joint action of multiple second limiting portions 46 and the second elastic portion 45; after the target plant components are cut, the multiple second limiting portions 46 are separated from the second elastic portion 45, and under the action of the rebound force of the second elastic portion 45, the packing bag 40 pulls the target plant components upward to disengage from the collecting cutter 33; the separation of the multiple first limiting portions 42 and the first elastic portion 41 precedes the separation of the multiple second limiting portions 46 and the second elastic portion 45.

[0048] Specifically, the cutting edge of the collecting cutter 33 will be worn after multiple times of picking the target plant components. In this way, the stems connected to some target plant components cannot be completely cut off. In addition, when the multiple first support plates 31 are in a semi-expanded state, the lowest point of the stems connected to the target plant components is lower than the lowest point where the multiple first support plates 31 contact the ground at the take-off and landing points. In this way, during the landing of the drone body 1, the radial compression of the ground will produce an extrusion effect on the packaged target plant components. Therefore, in order to avoid the above situation, in this embodiment, a second elastic portion 45 is arranged on the packaging bag 40, and the area between the first elastic portion 41 and the second elastic portion 45 is used for packaging the target plant components, and the first elastic portion 41 is radially compressed. The second elastic portion 45 contracts (elastically deforms) along the axial direction, and a second limiting portion 46 is correspondingly arranged on each second support plate 34. The second limiting portion 46 has a substantially identical structure to the first limiting portion 42. However, when the wire block 352 does not squeeze the pressure block 43, the planar structure of the hook of the second limiting portion 46 is inclined, and the high end of the inclination is closer to the packing bag 40 than the low end. That is, in the process of each second support plate 34 deflecting toward the packing bag 40, the separation of the plurality of first limiting portions 42 and the first elastic portion 41 precedes the separation of the plurality of second limiting portions 46 and the second elastic portion 45. In this way, the target plant component will be packed first, and then pulled toward the end of the wire rod 351, thereby avoiding the above-mentioned problem.

[0049] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the protection of the present invention.
