[0076] The infrared pair tube 40 is disposed on the upper side of the base 10 . The infrared pair tube 40 is a reflective infrared pair tube 40 . The infrared pair tube 40 is used to measure the height of the plants to be screened.

[0077] The lifting mechanism 50 is disposed on the upper side of the base 10 and is used to drive the camera 30 and the infrared tube 40 to rise and fall, so as to facilitate the camera 30 to capture images of the plants to be screened and the infrared tube 40 to measure the heights of the plants to be screened.

[0078] The lifting mechanism 50 includes a lifting screw 51, a lifting drive source 52 and a lifting block 53. Specifically, a vertical plate 11 is fixed to the upper side of the base 10, a support plate 12 is fixed to the upper side of the vertical plate 11, and the lifting screw 51 is vertically arranged. The two ends of the lifting screw 51 are rotatably connected to the base 10 and the support plate 12 respectively through bearings, and the lifting screw 51 is stationary relative to the base 10 in the axial direction. The lifting drive source 52 is a speed reducer, and the lifting drive source 52 is fixed to the upper side of the support plate 12. The output shaft of the lifting drive source 52 is fixedly connected to the upper end of the lifting screw 51 to drive the lifting screw 51 to rotate. The lifting block 53 is sleeved on the lifting screw 51. The lifting block 53 is threadedly connected to the lifting screw 51. The lifting block 53 does not rotate with the lifting screw 51. The lifting block 53 is lifted and lowered relative to the base 10 along the axial direction of the lifting screw 51. Specifically, the lifting block 53 can be abutted and slid against the vertical plate 11, or a guide shaft can be added that passes through the lifting block 53 and slides axially with the lifting block 53.

[0079] The camera 30 and the infrared pair tube 40 are both fixed on the side of the lifting block 53 facing away from the vertical plate 11, and the camera 30 and the infrared pair tube 40 are both arranged facing away from the lifting block 53. When measuring the plants to be selected, the infrared pair tube 40 is facing the plants to be screened, and the lifting mechanism 50 drives the infrared pair tube 40 to move upward from the base 10. When the infrared receiving tube of the infrared pair tube 40 cannot receive the signal emitted by the infrared transmitting tube, the height of the infrared pair tube 40 is the height of the plants to be screened, and the height of the infrared pair tube 40 driven by the lifting mechanism 50 can be calculated based on the height of the base 10 plus the height of the infrared pair tube 40.

[0080] Reference Figure 1 and Figure 2 The extending arm 60 is arranged on the upper side of the base 10. The extending arm 60 can be raised and lowered synchronously with the infrared tube 40 under the drive of the lifting mechanism 50. The extending arm 60 can extend out of the base 10 in the horizontal direction. The extending mechanism 80 is used to drive the extending arm 60 to extend out of the base 10.

[0081] The extending mechanism 80 includes an extending screw rod 81, an extending driving source 82, an extending driving block 83, a driving column 84 and a connecting rod 85. Specifically, the extending screw rod 81 is vertically arranged, and the two ends of the extending screw rod 81 are rotatably connected to the base 10 and the support plate 12 respectively through bearings, and the extending screw rod 81 is stationary relative to the base 10 in the axial direction. A sliding hole 531 is provided on the lifting block 53, and the extending screw rod 81 is inserted into the sliding hole 531.

The extending driving source 82 is a reducer, and the extending driving source 82 is fixed to the upper side of the support plate 12. The output shaft of the extending driving source 82 is fixedly connected to the upper end of the extending screw rod 81 to drive the extending screw rod 81 to rotate. The extension drive block 83 is sleeved on the extension screw rod 81 and the lifting screw rod 51. The extension drive block 83 is located on the upper side of the lifting block 53. The extension drive block 83 is threadedly connected with the extension screw rod 81. A through hole 831 is provided on the extension drive block 83. The lifting screw rod 51 is penetrated in the through hole 831. The lifting screw rod 51 is slidably connected with the extension drive block 83 along the axial direction to guide the extension drive block 83 to rise and fall without rotating with the extension screw rod 81. The extension arm 60 is hinged to one side of the extension drive block 83. An extension rod 61 is fixed to the side of the upper end of the extension arm 60 close to the vertical plate 11. The extension rod 61 and the extension arm 60 are perpendicular to each other. The drive column 84 is fixed to the side of the extension rod 61 close to the extension drive block 83. The hinge axis of the drive column 84 and the extension arm 60 are parallel to each other. The lower end of the connecting rod 85 is hinged to the lifting block 53, and the upper end of the connecting rod 85 is provided with a long waist hole 851, which is arranged along the length direction of the connecting rod 85. The driving column 84 is passed through the long waist hole 851. The driving column 84 can rotate in the long waist hole 851, and the driving column 84 can also slide in the long waist hole 851 along the length direction of the connecting rod 85.

[0082] The lifting mechanism 50 and the extending mechanism 80 drive the lifting block 53 and the extending driving block 83 to rise synchronously. When the infrared receiving tube of the infrared pair tube 40 cannot receive the signal emitted by the infrared transmitting tube, the lifting driving source 52 stops working, and the extending driving source 82 drives the extending driving block 83 to continue to rise. The connecting rod 85 forces the driving column 84 to descend relative to the extending driving block 83, thereby driving the extending arm 60 from a vertical state to extending the base 10 in a horizontal direction.

[0083] The coverage area measuring mechanism 70 is arranged at the end of the extension arm 60 that can extend out of the base 10, and the coverage area measuring mechanism 70 is used to detect the coverage area of ​​the plant.

The tension detection element 74 is a tension sensor, one end of the tension detection element 74 is fixedly connected to the movable end of the pull rope 73, and the other end of the tension detection element 74 is fixedly connected to the gravity cone 75.

[0084] When measuring the coverage area of ​​the plants to be screened, after the infrared receiving tube of the infrared pair tube 40 cannot receive the signal emitted by the infrared transmitting tube, the lifting drive source 52 stops working, and the extension drive source 82 drives the extension drive block 83 to continue to rise, driving the extension arm 60 from a vertical state to a horizontal direction, and the spool drive source 72 drives the spool 71 to release the line, so that the gravity cone 75 drops to the height of the base 10, and then controls the base 10 to approach the plants to be screened from three different directions, and obtains three contact points between the pull rope 73 and the plants to be screened according to the tension value output by the tension detection element 74. According to the triangle formed by the three contact points, the circumscribed circle area of ​​the triangle is calculated, which is the coverage area of ​​the plants to be screened. Here, the coverage area of ​​the plants to be screened is the projection area of ​​the plants to be screened on the horizontal plane.

[0085] Reference Figure 1 and Figure 3 In order to achieve the synchronous rise of the lifting block 53 and the extension drive block 83 in the early stage, the extension screw 81 and the lifting screw 51 are arranged in opposite directions, and the extension screw 81 is sleeved with a first gear 811, which is concentrically arranged with the extension screw 81 and can rotate synchronously with the extension screw 81. A base plate 13 is fixed on the vertical plate 11, and the base plate 13 abuts against the lower side of the first gear 811 to provide support for the first gear 811.

The first gear 811 and the second gear 511 are meshed with each other, and the first gear 811 and the second gear 511 have the same number of teeth.

[0086] The flower mirror plant screening device further includes a clutch mechanism 90 , which is used to drive the extended screw rod 81 and the first gear 811 to rotate synchronously or separately.

[0087] The clutch mechanism 90 includes a clutch shaft 91 . A clutch hole 92 is provided at the connection between the extended screw rod 81 and the first gear 811 . The clutch shaft 91 passes through the clutch hole 92 . The diameter of the clutch shaft 91 is equal to the diameter of the clutch hole 92 . The clutch shaft 91 can rotate in the clutch hole 92 . The clutch hole 92 includes a minor arc portion 8111 provided on the inner side wall of the first gear 811 and a major arc portion 812 provided on the extending screw rod 81. A clutch surface 911 is provided on the outer peripheral wall of the clutch shaft 91. The clutch surface 911 is a plane. When the clutch surface 911 is facing the minor arc portion 8111, the clutch shaft 91 is completely received in the major arc portion 812, and the first gear 811 is rotationally connected to the extending screw rod 81; when the clutch surface 911 deviates from the minor arc portion 8111, the clutch shaft 91 is partially received in the major arc portion 812 and partially received in the minor arc portion 8111, so that the first gear 811 and the extending screw rod 81 rotate synchronously.

[0088] In order to realize the automatic control of the clutch shaft 91, the clutch mechanism 90 also includes a toggle rod 93, a clutch sleeve 94, a reset elastic member 95 and a transmission block 96. The toggle rod 93 is fixed to the upper end of the clutch shaft 91. The toggle rod 93 and the clutch shaft 91 are perpendicular to each other. The clutch shaft 91 has two clutch surfaces 911. The two clutch surfaces 911 are parallel to each other and are arranged in a back-to-back manner. The toggle rod 93 is located between the two conversion surfaces. Two embedded grooves 813 are provided on the outer peripheral wall of the extended screw rod 81. The two embedded grooves 813 are connected to the superior arc portion 812. The two embedded grooves 813 are symmetrically arranged on both sides of the superior arc portion 812. When the clutch shaft 91 rotates in the clutch hole 92, the toggle rod 93 can be embedded in the embedded groove 813. When the toggle rod 93 is inserted into the embedded groove 813, one conversion surface faces the inferior arc portion 8111, and the other conversion surface faces away from the inferior arc portion 8111, and the first gear 811 is rotationally connected with the extended screw rod 81. When the toggle rod 93 is located between the two embedded grooves 813, the clutch shaft 91 is inserted into the superior arc portion 812 and the inferior arc portion 8111 at the same time, and the first gear 811 and the extended screw rod 81 are relatively fixed along the circumferential direction.

[0089] The lower part of the clutch sleeve 94 is sleeved with the upper end of the extended screw rod 81, and the clutch sleeve 94 is rotatably connected with the extended screw rod 81, and the inner circumferential wall of the clutch sleeve 94 does not contact the clutch shaft 91. The lower end of the clutch sleeve 94 is provided with a driving groove 941, and the toggle rod 93 is inserted into the driving groove 941. The size of the driving groove 941 is larger than the size of the toggle rod 93, so that when the clutch sleeve 94 and the extended screw rod 81 rotate relative to each other, the toggle rod 93 can be driven to drive the clutch shaft 91 to rotate in the clutch hole 92. After the toggle rod 93 is embedded in the embedded groove 813, the extended screw rod 81 rotates together with the clutch sleeve 94. The upper part of the clutch sleeve 94 is sleeved on the output shaft of the extended drive source 82, and the clutch sleeve 94 is concentric with the output shaft of the extended drive source 82 and the extended screw rod 81. A sliding groove 821 is provided on the outer peripheral wall of the output shaft of the extension drive source 82, and a transmission block 96 is disposed in the sliding groove 821 and can slide in the sliding groove 821 along the radial and axial directions of the output shaft of the extension drive source 82. When the output shaft of the extension drive source 82 rotates, the transmission block 96 can slide out of the sliding groove 821 under the action of centrifugal force. Two stoppers 942 are fixed on the inner peripheral wall of the clutch sleeve 94, and the two stoppers 942 are evenly arranged along the circumference of the clutch sleeve 94. When the output shaft of the extension drive source 82 rotates, the transmission block 96 can slide out of the driving groove 941 and limit each other with one of the stoppers 942, so that the extension drive source 82 can drive the clutch sleeve 94 to rotate.

[0090] The lower side of the sliding groove 821 has a guide surface 8211, which tilts from top to bottom toward the axis of the output shaft of the extension drive source 82, so that when the output shaft of the extension drive source 82 stops rotating, the guide surface 8211 can guide the transmission block 96 to be completely received in the sliding groove 821.

[0091] In order to prevent the guide surface 8211 from being scratched by the edges and corners of the transmission block 96 , a guide surface 961 is provided on the transmission block 96 , and the guide surface 961 is matched with the guide surface 8211 .

[0092] The reset elastic member 95 is a spring sheet, and the reset elastic member 95 is arranged in a quarter arc shape. After being bent, the two ends of the reset elastic member 95 are fixedly connected to the lower side of the toggle rod 93 and the outer peripheral wall of the extended screw rod 81 respectively. When the reset elastic member 95 is in a natural state, the toggle rod 93 is located between the two embedded grooves 813. The reset elastic member 95 makes the toggle rod 93 maintain a tendency to move to the middle of the two embedded grooves 813.

[0093] When it is necessary to drive the lifting block 53 and the extending drive block 83 to lift synchronously, the toggle rod 93 is located between the two grooves 813. At this time, the extending screw rod 81 and the first gear 811 rotate synchronously. The lifting drive source 52 drives the lifting screw rod 51 to rotate. The lifting screw rod 51 drives the extending screw rod 81 to rotate synchronously in the opposite direction through the engagement of the second gear 511 with the first gear 811. When it is necessary to drive the extension arm 60 to extend horizontally out of the base 10, the extension drive source 82 drives the transmission block 96 to slide out of the sliding groove 821 and limit the stop block 942 to each other, thereby driving the clutch sleeve 94 to rotate, and the clutch sleeve 94 drives the toggle rod 93 to embed into the embedded groove 813. At this time, the extension screw rod 81 is rotationally connected with the first gear 811, and the extension screw rod 81 is driven separately from the lifting screw rod 51. The lifting drive source 52 stops working, and then the extension drive source 82 drives the extension screw rod 81 to rotate, driving the extension drive block 83 to continue to rise, so that the extension arm 60 is changed from a vertical state to extend horizontally out of the base 10.

[0094] When the extension arm 60 needs to be changed from a horizontal state to a vertical state, the extension drive source 82 works to drive the extension transmission block 96 to slide out of the sliding groove 821 and limit each other with the stop block 942, thereby driving the clutch sleeve 94 to rotate, and the clutch sleeve 94 drives the toggle rod 93 to embed into the embedded groove 813. At this time, the extension screw rod 81 is rotationally connected with the first gear 811, and the extension screw rod 81 is driven separately from the lifting screw rod 51. The lifting drive source 52 does not work, and then the extension drive source 82 drives the extension screw rod 81 to rotate, and the extension screw rod 81 drives the extension drive block 83 to approach the lifting block 53. The extension arm 60 is changed from a horizontal state to a vertical state under the action of gravity.

[0095] The implementation principle of a flower mirror plant screening device in an embodiment of the present application is: an image of the plant to be screened is captured by a camera 30, and image comparison is used to determine whether the plant to be screened is the plant type in the required flower mirror type information; if so, a lifting mechanism 50 is used to drive the infrared pair tube 40 to rise and fall to measure the height of the plant to be screened, and a coverage area measuring mechanism 70 is used to measure the coverage area of ​​the plant to be screened, thereby assisting in the automatic screening of the flower mirror plants.

[0096] Reference Figure 4 , an embodiment of the present application also provides a method for screening plants in a flower mirror, and the main process of the method is described as follows.

[0097] Step 110: Obtain the type information of the flower mirror.

[0098] Among them, the flower mirror type information refers to the type of flower mirror, such as specialized plant flower mirror, hybrid flower mirror, etc.

[0099] Step 120: Retrieving plant information corresponding to the flower mirror type information from a flower mirror database according to the flower mirror type information.

[0100] The flower mirror database stores which plants each flower mirror type needs to consist of, that is, the plant information corresponding to the flower mirror type information.

[0101] Step 130: Acquire images of plants to be screened.

[0102] The flower mirror plant screening device is operated so that the camera 30 faces the plants to be screened, and the camera 30 is used to capture images of the plants to be screened.

[0103] Step 140: judging whether the plant to be screened includes the plant information corresponding to the flower mirror type information according to the image of the plant to be screened.

[0104] Among them, it is determined by image comparison whether the plant to be screened belongs to one of the plants corresponding to the flower mirror type information, and the plant information includes species information, and the species information refers to the species of the plant.

[0105] Step 150: If yes, obtain the height and coverage area of ​​the plants to be screened, otherwise, return to the step of obtaining the image of the plants to be screened.

[0106] If the plant to be screened belongs to one of the plants corresponding to the flower mirror type information, the lifting mechanism 50 is controlled to drive the lifting block 53 to rise from the base 10. When the infrared receiving tube of the infrared pair tube 40 cannot receive the signal emitted by the infrared transmitting tube, the height of the infrared pair tube 40 is the height of the plant to be screened. After the infrared receiving tube of the infrared pair tube 40 cannot receive the signal emitted by the infrared transmitting tube, the extension drive source 82 drives the extension drive block 83 to continue to rise, driving the extension arm 60 to change from a vertical state to a horizontal extension state of the base 10, and the coverage area of ​​the plant to be screened is measured by the coverage area measurement mechanism 70. The coverage area refers to the projection of the plant to be screened in the horizontal direction.

[0107] Step 160: Determine whether the height and coverage area of ​​the plants to be screened conform to the plant information corresponding to the flower mirror type information.

[0108] Among them, plant information also includes height information and coverage area information. The coordination of flower mirror plants needs to consider the height and coverage area of ​​the plants.

[0109] Step 170: If yes, output a reminder message; otherwise, return to the step of obtaining the image of the plant to be screened.

[0110] Among them, if the height and coverage area of ​​the plants to be screened are consistent with the plant height information and coverage area information corresponding to the flower mirror type information, then the consistent reminder information is output. The consistent reminder information can be light information, sound information, or vibration information.

[0111] The method for obtaining the coverage area of ​​the plants to be screened is:

[0112] Step 151: Control the extending arm 60 to extend out of the base 10 according to the height of the plants to be screened.

[0113] Among them, after the infrared receiving tube of the infrared pair tube 40 fails to receive the signal emitted by the infrared emitting tube, the extension driving source 82 drives the extension driving block 83 to continue to rise, driving the extension arm 60 to change from a vertical state to a horizontal extension base 10 state.

[0114] Step 152 : Control the spool driving source 72 to drive the gravity cone 75 down to the height where the base 10 is located.

[0115] Step 153: Control the base 10 to approach the plants to be screened from three directions respectively, and obtain the contact points between the pull rope 73 and the plants to be screened in the three directions.

[0116] Among them, when the base 10 is approaching the plant to be screened, when the pull rope 73 is not in contact with the plant to be screened, the tension output by the tension detection element 74 is the gravity of the gravity cone 75. When the pull rope 73 is in contact with the plant to be screened, the gravity cone 75 will swing under the action of inertia, so that the tension output by the tension detection element 74 is greater than the gravity of the gravity cone 75. The contact point between the pull rope 73 and the plant to be screened is determined by the change in the tension output by the tension detection element 74.

[0117] Step 154: Calculate the coverage area of ​​the plants to be screened based on the three contact points.

[0118] Among them, according to the triangle formed by the three contact points, the area of ​​the circumscribed circle of the triangle is calculated to be the coverage area of ​​the plants to be screened.
