Description

Technical Field

[0001] This invention relates to a pear tree fruit thinning device and method, and more particularly to a pear tree fruit thinning device and method based on the redistribution and arrangement of young fruits. Background Technology

[0002] Thinning pear fruit allows for a more balanced tree load, reducing nutrient waste and improving fruit quality. It also promotes flower bud differentiation, regulates alternate bearing, and ensures stable, consistent yields year after year. Therefore, pear fruit thinning devices are important horticultural tools. However, current pear fruit thinning devices do not focus on the redistribution of young fruit. Instead, they remove excess deformed, diseased, small, and easily rubbed young fruit from branches. This necessitates individual removal of each young fruit, thus reducing the efficiency of pear fruit thinning. This invention explores and studies the technical characteristics of fruit stalk rearrangement and cutting under the interference of external gaps in pear trees, and effectively addresses the technical problem of pruning away excess deformed fruits, diseased fruits, small fruits, and young fruits that are prone to friction with branches.

[0057] Related technical solution number thirty-nine is a method for using a pear tree fruit thinning device based on the redistribution of young fruits. The steps are as follows: the palm seat ring connects and supports the expansion step rod assembly; the expansion step rod assembly performs outward distribution of young fruits that need to be thinned and neutral distribution of young fruits that need to be retained; the laser performs burning treatment on the fruit stalks of young fruits that need to be thinned; thus, the fruit stalks of pear trees that need to be thinned are redistributed and cut off under the influence of external gap interference.

[0059] The fortieth related technical solution comprises the following steps: When rod I is placed into receiving hole I, the transverse nut rotates on the cylindrical bolt of rod I, adjusting the position of the rectangular rod of rod I within receiving hole I, thereby adjusting the compression state of the transverse spring; when the vertical nut rotates on rod II, the height position of the cylinder in rod II is adjusted, thereby adjusting the compression state of the vertical spring; when the screw rotates within receiving hole II, the height of the ball head is adjusted; when the first telescopic cylinder is in the retracted state, the closing rope located between the first telescopic cylinder, the bottom finger rod, and the battery box moves within the through hole of the protrusion and the inclined through hole of the lower beam, causing the closing rope located between the first telescopic cylinder, the bottom finger rod, and the battery box to move... When the first telescopic cylinder retracts, overcoming the transverse spring, rod I moves inward within the receiving hole I, causing strip I to move inward along the radial line of the ring, bringing strip I to a closed state. When the first telescopic cylinder is in the extended state, the closing rope located between the first telescopic cylinder, the bottom finger rod, and the battery box moves in the opposite direction within the through hole of the protrusion and the oblique through hole of the lower beam. The closing rope located between the first telescopic cylinder, the bottom finger rod, and the battery box is released. Under the elastic energy storage of the transverse spring, rod I moves outward within the receiving hole I, causing strip I to move outward along the radial line of the ring, bringing strip I to an expanded state. When the second telescopic cylinder is in the retracted state, the pulling rope located between the second telescopic cylinder, the lifting seat, the middle finger rod, and the battery box moves in the receiving hole IV and the middle beam. The cylinder moves inward through the inclined through-hole, overcoming the vertical spring, causing the cylinder to move downward on rod II, bringing the side-pressure claw I and side-support claw I into a closed state, and bringing the side-pressure claw II and side-support claw II into a closed state. When the second telescopic cylinder is in the extended state, the pulling rope located between the second telescopic cylinder and the lifting seat, the middle finger rod, and the battery box moves outward through the inclined through-hole of the receiving hole IV and the intermediate beam. Under the elastic energy storage of the vertical spring, the cylinder moves upward on rod II, bringing the side-pressure claw I and side-support claw I into a separated state, and bringing the side-pressure claw II and side-support claw II into a separated state. When the third telescopic cylinder is in the retracted state, the closing rope located between the third telescopic cylinder and the top finger rod and the battery box moves upward on the upper beam. The movement within the oblique through-hole causes the closing rope located between the third telescopic cylinder, the top finger rod, and the battery box to contract, overcoming the first torsion spring. This allows the receiving hole III to rotate inward along the pin shaft located between the middle and bottom fingers, causing strip II to rotate inward and the ball head to be in a closed state. When the third telescopic cylinder is in an extended state, the closing rope located between the third telescopic cylinder, the top finger rod, and the battery box moves in the opposite direction within the oblique through-hole of the upper beam. The closing rope between the third telescopic cylinder, the top finger rod, and the battery box is released. Under the elastic energy storage of the first torsion spring, the receiving hole III rotates outward along the pin shaft located between the middle and bottom fingers, causing strip II to rotate outward and the ball head to be in an expanded state. When fruit thinning of the pear tree is required, the size of the young fruit to be thinned out is adjusted accordingly.Based on the spacing between the receiving holes I, select the position of the receiving hole I of the mounting bracket component. Install the bottom finger rod onto the palm seat ring using a transverse spring and a transverse nut. Install the closing rope between the first telescopic cylinder, the bottom finger rod, and the battery box between the first telescopic cylinder, the lower beam, and the protrusion. Install the pulling rope between the second telescopic cylinder, the lifting seat, the middle finger rod, and the battery box between the second telescopic cylinder, the middle beam, the receiving hole IV, and the plate II. Install the closing rope between the third telescopic cylinder, the top finger rod, and the battery box between the third telescopic cylinder, the upper beam, and the ball head. Adjust the height of the bulb head according to the desired fruit stalk length to be retained, ensuring the bulb head height corresponds to the desired fruit stalk length. Connect the spray head's input interface to the high-pressure source of the pear fruit nutrient solution via a valve. The operator holds the handle and places the ring at the desired pear tree thinning location. By controlling the switch, the first, second, and third telescopic cylinders, camera, and signal processor are activated. When strip I and the bulb head are closed respectively, the fruit to be thinned leaks out through the gap between adjacent stem II, allowing the desired fruit to be removed. The fruit stalks to be removed are located on the side-supporting claws I and II. The young fruit must not leak out through the gap between adjacent stalks II; it must remain on the head of the fruit. The side-pressure claws I and side-supporting claws I and II are closed, clamping and fixing the fruit stalks to be removed. The laser is then activated, burning off the fruit stalks. After burning off the stalks, the laser is deactivated, and the side-pressure claws I and side-supporting claws... With claw I in the separated state and side-pressure claw II and side-support claw II in the separated state, the input interface of the spray head is connected to the high-pressure source of the pear fruit nutrient solution, allowing the spray head to spray the pear fruit nutrient solution onto the fruit that needs to be retained. After spraying the fruit that needs to be retained, the input interface of the spray head is disconnected from the high-pressure source of the pear fruit nutrient solution, causing strip I to close and the ball head to expand. Then, the ring is placed at the next location on the pear tree where fruit thinning is needed. The thinning process is captured and stored using a camera and signal processor.

[0060] The forty-first related technical solution involves the following steps: When the adjusting screw rotates in the threaded hole of the transverse swing rod, the height of the actuating ball is adjusted. When the third telescopic cylinder is in the retracted state, the pulling rope located between the third telescopic cylinder and the transverse swing rod, the top finger rod, and the battery box moves in the through hole of the screw part and the oblique through hole of the upper beam part, overcoming the elastic energy storage of the second torsion spring. The U-shaped opening of the transverse swing rod rotates inward in the pin shaft located between the transverse swing rod and the top finger rod, causing the actuating ball to swing outward. When the third telescopic cylinder is in the extended state, the pulling rope located between the third telescopic cylinder and the transverse swing rod, the top finger rod, and the battery box moves in the through hole of the screw part and the oblique through hole of the upper beam part. The upper beam moves in the opposite direction through the inclined through-hole. Under the elastic energy storage of the second torsion spring, the U-shaped opening of the transverse swing rod rotates outward along the pin shaft located between the transverse swing rod and the top finger rod, bringing the agitator ball to its initial state. When fruit thinning of pear trees is required, the agitator ball at the head is adjusted according to the required fruit stalk length, so that the height of the agitator ball corresponds to the length of the fruit stalk to be retained. When the ball head is in the closed state, the agitator ball swings outward, acting on the pear tree where fruit thinning is needed. The young fruit to be thinned protrudes outward from the gap between adjacent stem sections II, so that the fruit stalks to be thinned are located on the side-supporting claw sections I and II. The side-pressure claw section I and the side-supporting claw section I are in a closed state, and the side-pressure claw section II and the side-supporting claw section II are in a closed state, clamping and fixing the fruit stalks to be thinned. The image of the pear tree to be thinned is captured and processed by the camera and signal processor. The signal processor selects the young fruit to be thinned, and the laser located on the side-supporting claw sections I and II that hold the fruit stalks to be thinned is put into working state. The laser burns off the fruit stalks to be thinned. After the fruit stalks to be thinned are burned off, the laser is put into a non-working state, and the side-pressure claw section I and the side-supporting claw section I are in a separated state, and the ball head is in an expanded state, so that the ball is in the initial state.

[0061] The technical effect of the above two solutions is that they enable a continuous thinning process for pear trees.

[0062] In this technical solution, the palm rest ring and laser are basic components and essential technical features of the invention. The bottom finger rod, transverse spring, transverse nut, middle finger rod, first torsion spring, lifting seat, vertical nut, vertical spring, top finger rod, battery box, first telescopic cylinder, second telescopic cylinder, third telescopic cylinder, camera, signal processor, spray head, transverse swing rod, adjusting screw, actuating ball, and second torsion spring are functional components that enable other technical effects of the invention.

[0063] In this technical solution, the fruit stalks that require fruit thinning in the pear tree are arranged in an arranged state, which is achieved by the expansion step rod assembly.

[0118] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0119] A method for using a pear tree fruit thinning device based on the redistribution and arrangement of young fruits, one of the first embodiments of the present invention, includes the following steps: When rod I22 is placed into receiving hole I12, the transverse nut 4 is rotated on the cylindrical bolt of rod I22, adjusting the position of the rectangular rod of rod I22 within receiving hole I12, thereby adjusting the compression state of transverse spring 3. When the vertical nut 7 rotates on the rod II 52, the height position of the cylinder 61 on the rod II 52 is adjusted, thereby adjusting the compression state of the vertical spring 8. When the screw section 912 rotates within the receiving hole body II 56, the height of the ball head 911 is adjusted. When the first telescopic cylinder 93 is in the retracted state, the closing rope located between the first telescopic cylinder 93, the bottom finger rod 2, and the battery box 92 moves in the through hole of the protrusion 23 and the oblique through hole of the lower beam 922. The closing rope located between the first telescopic cylinder 93, the bottom finger rod 2, and the battery box 92 retracts, overcoming the transverse spring 3. The rod I22 moves inward in the receiving hole I12, causing the strip I21 to move inward along the radial line of the ring 11, so that the strip I21 is in the closed state. When the first telescopic cylinder 93 is in the retracted state, the closing rope moves inward in the through hole of the protrusion 23 and the oblique through hole of the lower beam 922. When cylinder 93 is in the extended state, the closing rope located between the first telescopic cylinder 93, the bottom finger rod 2, and the battery box 92 moves in opposite directions within the through hole of the protrusion 23 and the oblique through hole of the lower beam 922. The closing rope between the first telescopic cylinder 93, the bottom finger rod 2, and the battery box 92 is released. Under the elastic energy storage action of the transverse spring 3, the rod I22 moves outward in the receiving hole I12, causing the strip I21 to move outward along the radial line of the ring 11, thus putting the strip I21 into an expanded state. When the second telescopic cylinder 94 is in the retracted state, the pull rope located between the second telescopic cylinder 94 and the lifting seat 6, the middle finger rod 5, and the battery box 92 moves inward in the inclined through-hole of the receiving hole Ⅳ58 and the intermediate beam 923, overcoming the vertical spring 8, causing the cylinder 61 to move downward on the rod Ⅱ52, causing the side pressure claw Ⅰ63 and the side support claw Ⅰ54 to be in a closed state, and the side pressure claw Ⅱ64 and the side support claw Ⅱ55 to be in a closed state. When the telescopic cylinder 94 is in the extended state, the pulling rope located between the second telescopic cylinder 94 and the lifting seat 6, the middle finger rod 5, and the battery box 92 moves outward in the oblique through-hole of the receiving hole IV 58 and the intermediate beam 923. Under the elastic energy storage of the vertical spring 8, the cylinder 61 moves upward on the rod II 52, causing the side pressure claw I 63 and the side support claw I 54 to separate, and the side pressure claw II 64 and the side support claw II 55 to separate. When the third telescopic cylinder 95 is in the retracted state, the closing rope located between the third telescopic cylinder 95, the top finger rod 91, and the battery box 92 moves in the inclined through hole of the upper beam 924. The closing rope between the third telescopic cylinder 95, the top finger rod 91, and the battery box 92 retracts, overcoming the first torsion spring 90. The receiving hole Ⅲ57 rotates inward along the pin axis located between the middle finger rod 5 and the bottom finger rod 2, causing the strip Ⅱ51 to rotate inward, so that the ball head 911 is in the closed state. When the third telescopic cylinder 95 is in the retracted state, the closing rope moves inward along the upper beam 924. When cylinder 95 is in the extended state, the closing rope located between the third telescopic cylinder 95, the top finger rod 91, and the battery box 92 moves in the opposite direction in the oblique through hole of the upper beam 924. The closing rope located between the third telescopic cylinder 95, the top finger rod 91, and the battery box 92 is released. Under the elastic energy storage action of the first torsion spring 90, the receiving hole Ⅲ57 rotates outward along the pin shaft located between the middle finger rod 5 and the bottom finger rod 2, causing the strip Ⅱ51 to rotate outward, and causing the ball head 911 to be in the expanded state. When fruit thinning is required on pear trees, the position of the receiving hole I12 of the mounting bracket component is selected according to the size of the young fruit to be thinned and the spacing between the receiving holes I12. The bottom finger rod 2 is installed on the palm seat ring 1 by means of the transverse spring 3 and the transverse nut 4. The closing rope located between the first telescopic cylinder 93 and the bottom finger rod 2 and the battery box 92 is installed between the first telescopic cylinder 93, the lower beam 922 and the protrusion 23. The pulling rope located between the second telescopic cylinder 94 and the lifting seat 6, the middle finger rod 5 and the battery box 92 is installed between the second telescopic cylinder 94, the middle beam 923, the receiving hole IV 58 and the plate II 62. The rope located between the third telescopic cylinder 95 and the top finger rod 91 and the battery box 92 is installed between the third telescopic cylinder 95 and the top finger rod 91 and the battery box 92. The closing rope between boxes 92 is installed between the third telescopic cylinder 95, the upper beam 924, and the ball head 911. The height of the ball head 911 is adjusted to correspond to the desired length of the fruit stalk to be retained. The input interface of the spray head 98 is connected to the high-pressure source of the pear fruit nutrient solution via a valve. The operator holds the handle 925 and places the ring 11 at the desired pear tree thinning location. By controlling the switch, the first telescopic cylinder 93, the second telescopic cylinder 94, the third telescopic cylinder 95, the camera 96, and the signal processor 97 are activated. This ensures that the strip I21 and the ball head 911 are closed. In the first stage, the young fruit needs to be removed from the gap between adjacent stems II52, so that the fruit stalks to be removed are located on the side-supporting claws I54 and II55. The young fruit must not leak out from the gap between adjacent stems II52; it must remain on the ball head 911. The side-pressing claws I63 and I54, and the side-supporting claws II64 and II55 are closed, clamping and fixing the fruit stalks to be removed. The laser 9 is then in working mode, burning off the fruit stalks. After burning off the fruit stalks, the laser 9 is deactivated. The side-pressure claw I63 and the side-support claw I54 are separated, and the side-pressure claw II64 and the side-support claw II55 are separated. The input interface of the spray head 98 is connected to the high-pressure source of the pear fruit nutrient solution. The spray head 98 sprays the pear fruit nutrient solution onto the fruit that needs to be retained. After the pear fruit nutrient solution spraying is completed, the input interface of the spray head 98 is disconnected from the high-pressure source of the pear fruit nutrient solution. The strip I21 is closed and the ball head 911 is expanded. Then the ring 11 is placed at the next pear tree thinning position. The thinning process is captured and stored by the camera 96 ​​and the signal processor 97.

[0120] A pear tree fruit thinning device based on the redistribution and arrangement of young fruits. Figure 4This is the third embodiment of the first embodiment of the present invention. The embodiment is described in detail with reference to the accompanying drawings. It includes a lateral swing rod 10, an adjusting screw 20, a toggle ball 30, and a second torsion spring 40. The lateral swing rod 10 is mounted on a top finger rod 91. The second torsion spring 40 is positioned between the lateral swing rod 10 and the top finger rod 91. The adjusting screw 20 is mounted on the lateral swing rod 10. The toggle ball 30 is mounted on the adjusting screw 20. A pull rope is positioned between the third telescopic cylinder 95 and the lateral swing rod 10, the top finger rod 91, and the battery box 92.

[0121] In this embodiment, the transverse swing rod 10 is configured as a strip with a U-shaped opening at one end and a threaded hole at the other end. The U-shaped opening of the transverse swing rod 10 is connected to the screw part 912 via a pin. One end of the transverse swing rod 10 is connected to the second torsion spring 40, and the threaded hole of the transverse swing rod 10 is connected to the adjusting screw 20.

[0122] In this embodiment, a through hole is provided on the screw part 912, and one end of the pull rope located between the third telescopic cylinder 95 and the transverse swing rod 10, the top finger rod 91 and the battery box 92 is connected to the inner side of the other end of the transverse swing rod 10. The other end of the pull rope located between the third telescopic cylinder 95 and the transverse swing rod 10, the top finger rod 91 and the battery box 92 is connected to the telescopic end of the third telescopic cylinder 95. One end of the pull rope located between the third telescopic cylinder 95 and the transverse swing rod 10, the top finger rod 91 and the battery box 92 is connected through the through hole of the screw part 912 and the oblique through hole of the upper beam part 924.

[0123] The transverse swing rod 10 forms a support connection point for the top finger rod 91, the adjusting screw 20, and the second torsion spring 40. The transverse swing rod 10 realizes the connection with the top finger rod 91, the connection with the adjusting screw 20, and the connection with the second torsion spring 40. Its technical purpose is to be used as one of the components for pushing the pear tree fruit thinner outward.

[0124] In this embodiment, the adjusting screw 20 is configured as an internal hexagonal bolt and is threadedly connected to the transverse swing arm 10. The inner end face of the transverse swing arm 10 is configured to be connected to the actuating ball 30.

[0125] By adjusting the screw 20, a support connection point is formed for the transverse swing rod 10 and the agitator ball 30. The adjustment screw 20 realizes the connection with the transverse swing rod 10 and the connection with the agitator ball 30. Its technical purpose is to be used as the second component for pushing the pear tree fruit thinner outward.

[0126] In this embodiment, the actuating ball 30 is configured as a spherical body and the inner end of the peripheral side of the actuating ball 30 is configured to be connected to the adjusting screw 20.

[0127] By actuating the ball 30, a support connection point for the adjusting screw 20 is formed. The ball 30 is used to connect with the adjusting screw 20. Its technical purpose is to serve as the third component for outward manipulation of pear trees that require fruit thinning.

[0128] In this embodiment, the second torsion spring 40 is configured as a single torsion spring and is configured to be connected to the pin assembly between the transverse swing arm 10 and the top finger rod 91. One end of the second torsion spring 40 is configured to be connected in contact with the transverse swing arm 10 and the top finger rod 91.

[0129] The second torsion spring 40 forms a support connection point for the transverse swing rod 10 and the top finger rod 91. The second torsion spring 40 realizes the connection with the transverse swing rod 10 and the connection with the top finger rod 91. Its technical purpose is to be used as the fourth component for pushing the pear tree fruit thinner outward.

[0130] A method for using a pear tree fruit thinning device based on the redistribution and arrangement of young fruits, the third embodiment of the present invention, comprises the following steps: When the adjusting screw 20 rotates in the threaded hole of the transverse swing rod 10, the height of the actuating ball 30 is adjusted. When the third telescopic cylinder 95 is in the retracted state, the pull rope located between the third telescopic cylinder 95 and the transverse swing rod 10, the top finger rod 91, and the battery box 92 moves in the through hole of the screw part 912 and the oblique through hole of the upper beam part 924, overcoming the elastic energy stored in the second torsion spring 40. The U-shaped opening of the transverse swing rod 10 rotates inward in the pin shaft located between the transverse swing rod 10 and the top finger rod 91, causing the actuating ball 30 to swing outward. When the third telescopic cylinder 95 is in the extended state, the pull rope located between the third telescopic cylinder 95 and the transverse swing rod 10, the top finger rod 91, and the battery box 92 moves in the opposite direction in the through hole of the screw part 912 and the oblique through hole of the upper beam part 924. Under the elastic energy stored in the second torsion spring 40, the U-shaped opening of the transverse swing rod 10 rotates outward in the pin shaft located between the transverse swing rod 10 and the top finger rod 91, causing the actuating ball 30 to return to its initial state. When fruit thinning is required on pear trees, the adjusting ball 30 of the ball head 911 is adjusted according to the required fruit stalk length, so that the height of the adjusting ball 30 corresponds to the length of the fruit stalk to be retained for the young fruit. When the ball head 911 is in the closed state, the agitator ball 30 swings outward, acting on the pear tree where fruit thinning is needed. The young fruit to be thinned protrudes outward from the gap between adjacent stem sections II 52, so that the fruit stalks of the young fruit to be thinned are located on the side-supporting claw sections I 54 and II 55. This causes the side-pressing claw section I 63 to be closed with the side-supporting claw section I 54, and the side-pressing claw section II 64 to be closed with the side-supporting claw section II 55, clamping and fixing the fruit stalks of the pear tree where fruit thinning is needed. The image of the pear tree where fruit thinning is needed is captured and processed by the camera 96 ​​and the signal processor 97, and the signal processor 97 selects the young fruit to be thinned. The laser 9, located on the side-support claw I54 and side-support claw II55 holding the fruit stalks that need to be thinned, is put into working state. The laser 9 burns off the fruit stalks that need to be thinned. After the fruit stalks that need to be thinned are burned off, the laser 9 is put into non-working state, the side-pressure claw I63 and the side-support claw I54 are separated, the side-pressure claw II64 and the side-support claw II55 are separated, the ball head 911 is in an expanded state, and the agitating ball 30 is in the initial state.

[0131] In verifying this invention, the inventors abandoned the existing technical features of simply pruning away excess deformed fruits, diseased and insect-infested fruits, small fruits, and young fruits that easily rub against branches. They first proposed a technical feature that allows for the rearrangement and cutting of fruit stalks under the interference of external interstitial structures in pear trees requiring fruit thinning. This resulted in the first unexpected technical effect: achieving holistic thinning of young fruits that need to be removed, improving the fruit thinning effect of pear trees. The second unexpected technical effect: achieving the rearrangement of fruit stalks through the palm base ring 1, middle finger rod 5, first torsion spring 90, and top finger rod 91, improving the identification effect of young fruits that need to be removed. The third unexpected technical effect: achieving the rearrangement of fruit stalks through the bottom finger rod 2 and transverse spring 3... The radial position of the middle finger rod 5 is adjusted by the horizontal nut 4, generating an outward swing force for the fruit stalks to be thinned, improving the placement of the fruit stalks on the middle finger rod 5. This results in the fourth unexpected technical effect: the fruit stalks to be thinned are clamped and positioned using the lifting seat 6, vertical nut 7, and vertical spring 8, improving the burning effect of the laser 9 on the fruit stalks. This results in the fifth unexpected technical effect: the fruit stalks to be thinned are burned by the laser 9, improving the self-healing effect of the cut end of the fruit stalk and preventing disease on the cut end. This results in the sixth unexpected technical effect: the battery box 92 serves as a supporting carrier, enabling self-contained... The power supply was optimized, resulting in the seventh unexpected technical effect: the rope was pulled via the first telescopic cylinder 93, the second telescopic cylinder 94, and the third telescopic cylinder 95, ensuring automatic operation of the fruit thinning process. This resulted in the eighth unexpected technical effect: images of the fruit thinning process were obtained through the camera 96 ​​and signal processor 97, providing research data and improving the operator's observation accuracy. This resulted in the ninth unexpected technical effect: nutrient solution was sprayed onto the young fruits to be retained via the spray head 98, achieving a coordinated operation of foliar fertilizer application. This resulted in the tenth unexpected technical effect: the use of the horizontal swing rod 10, adjusting screw 20, actuating ball 30, and second torsion spring 40... For pear trees requiring fruit thinning, the fruit is laid out flat, enabling intelligent fruit thinning through image recognition. This yielded an eleventh unexpected technical effect: the system uses a horizontal swing rod 10, adjusting screw 20, actuating ball 30, second torsion spring 40, camera 96, and signal processor 97 to identify the fruit thinning status of the pear trees. By comparing and identifying fruits in the same thinning position, the system ensures that the remaining young fruits are in a relatively vigorous growth state, resulting in a twelfth unexpected technical effect: the system no longer only removes excess deformed, diseased, insect-infested, small, and easily rubbed young fruits, reducing the chance of human interference with the remaining young fruits and allowing them to grow naturally.A thirteenth unexpected technical effect was achieved: the technology of thinning pear trees by arranging the fruit stalks in a specific position was introduced, changing the thinning posture of the pear tree and reducing the number of steps required for leaving or removing young fruit stalks, thus providing safety and preventing disease in the pear trees.

[0132] In the second embodiment of the present invention, the palm seat ring 1, the expansion step rod assembly and the laser 9 are interconnected in a manner that allows the fruit stalks of the pear tree that need to be thinned to be arranged in a thinning state.

[0133] In this embodiment, the expansion step rod assembly is connected to the palm seat ring 1 and the laser 9 in a manner that requires fruit thinning of pear trees and the rearrangement and distribution of fruit stalks under the interference of the fence pole.

[0134] In this embodiment, the expansion step rod assembly includes a middle finger rod 5, a first torsion spring 90, a lifting seat 6, a vertical nut 7, a vertical spring 8, and a top finger rod 91.

[0135] In this embodiment, a first accessory device is also included, and the first accessory device is configured to include a bottom finger rod 2, a transverse spring 3, and a transverse nut 4.

[0136] In this embodiment, a second accessory device is also included, and the second accessory device is configured to include a battery box 92, a first telescopic cylinder 93, a second telescopic cylinder 94, and a third telescopic cylinder 95.

[0137] In this embodiment, a third accessory device is also included, and the third accessory device is configured to include a camera 96 ​​and a signal processor 97.

[0138] In this embodiment, a fourth accessory device is also included, and the fourth accessory device is configured to include a spray head 98.

[0139] The second embodiment of the present invention is based on the first embodiment. The second embodiment of the present invention comprises the following steps: the palm seat ring 1 connects and supports the expansion step rod assembly; the expansion step rod assembly distributes the young fruits that need to be thinned outwards and distributes the young fruits that need to be left in a neutral position; and the laser 9 burns off the fruit stalks that need to be thinned, thereby enabling the fruit stalks of the pear tree that need to be thinned to be rearranged and cut off under the interference of external gaps.

[0140] The second embodiment of the present invention is based on the first embodiment. This invention has the following characteristics: 1. By designing the palm seat ring 1, the expansion step rod assembly, and the laser 9, the palm seat ring 1 connects and supports the expansion step rod assembly. The expansion step rod assembly enables the outward distribution of young fruits that need to be thinned and the neutral distribution of young fruits that need to be retained. The laser 9 enables the burning and severing of the fruit stalks of young fruits that need to be thinned. This allows the fruit stalks of pear trees to be rearranged and cut off under the influence of external gaps, solving the technical problem of pruning excess deformed fruits, diseased and insect-infested fruits, small fruits, and young fruits that are easy to rub against branches. Therefore, the fruit thinning efficiency of pear trees is improved.

[0141] 2. By designing the middle finger rod 5, the first torsion spring 90, the lifting seat 6, the vertical nut 7, the vertical spring 8, and the top finger rod 91, the rod interference effect is achieved for the pear tree that needs fruit thinning.

[0142] 3. Due to the design of the bottom finger rod 2, the transverse spring 3 and the transverse nut 4, the radial position adjustment of the middle finger rod 5 is realized.

[0143] 4. Due to the design of the battery box 92, the first telescopic cylinder 93, the second telescopic cylinder 94 and the third telescopic cylinder 95, the rope body can be driven to move.

[0144] 5. Due to the design of camera 96 ​​and signal processor 97, dynamic image signals of fruit and vegetable sorting were captured.

[0145] 6. Thanks to the design of the spray head 98, nutrient solution can be sprayed onto the young fruits that need to be left intact.

[0146] 7. Due to the design of the horizontal swing rod 10, the adjusting screw 20, the agitator ball 30 and the second torsion spring 40, the pear trees that need to be thinned can be agitated and laid flat.

[0147] 8. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or by a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0148] 9. Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.

[0149] Other technical features that connect the palm seat ring 1, the expansion step rod assembly, and the laser 9 to the pear tree fruit stalks that require thinning in an arranged state are also embodiments of the present invention.

The side-pressure claw I (63) and side-supporting claw I (54) are closed, and the side-pressure claw II (64) and side-supporting claw II (55) are closed. The fruit stalks from which the young fruit needs to be removed are clamped and fixed. The laser (9) is in working condition. The laser (9) burns off the fruit stalks from which the young fruit needs to be removed. After burning off the fruit stalks from which the young fruit needs to be removed, the laser (9) is deactivated. The side-pressure claw I (63) and side-supporting claw I (54) are separated, and the side-pressure claw II (64) and side-supporting claw II (55) are closed. II (55) is in a separated state, so that the input interface of the spray head (98) is connected to the high-pressure source of the pear fruit nutrient solution, so that the spray head (98) sprays the pear fruit nutrient solution on the fruit that needs to be retained. After the pear fruit nutrient solution spraying is completed on the fruit that needs to be retained, the input interface of the spray head (98) is disconnected from the high-pressure source of the pear fruit nutrient solution, so that the strip I (21) is in a closed state and the ball head (911) is in an open state. Then the ring (11) is placed in the next pear tree thinning position. The thinning process is captured and stored by the camera (96) and the signal processor (97). Alternatively, the steps are: When the adjusting screw (20) rotates in the threaded hole of the transverse swing rod (10), the height of the actuating ball (30) is adjusted. When the third telescopic cylinder (95) is in the retracted state, the pull rope located between the third telescopic cylinder (95) and the transverse swing rod (10), the top finger rod (91), and the battery box (92) moves in the through hole of the screw part (912) and the oblique through hole of the upper beam part (924), overcoming the elastic energy storage of the second torsion spring (40). The U-shaped opening of the transverse swing rod (10) rotates inward in the pin shaft located between the transverse swing rod (10) and the top finger rod (91), causing the actuating ball (30) to swing outward. When the third telescopic cylinder (95) is in the extended state, the pull rope located between the third telescopic cylinder (95) and the transverse swing rod (10), the top finger rod (91), and the battery box (92) moves in the threaded hole of the screw part (912) and the oblique through hole of the upper beam part (924), overcoming the elastic energy storage of the second torsion spring (40). The through-hole of the rod (912) and the oblique through-hole of the upper beam (924) move in opposite directions. Under the elastic energy storage of the second torsion spring (40), the U-shaped opening of the transverse swing rod (10) rotates outward in the pin shaft located between the transverse swing rod (10) and the top finger rod (91), so that the agitator ball (30) is in the initial state. When it is necessary to thin the pear tree, the agitator ball (30) of the ball head (911) is adjusted according to the length of the fruit stalk to be thinned, so that the height of the agitator ball (30) corresponds to the length of the fruit stalk to be left. When the ball head (911) is in the closed state, the agitator ball (30) swings outward and acts on the pear tree to be thinned. The young fruits that need to be thinned outwards from the gap between adjacent stems II (52), so that the fruit stalks of the young fruits to be thinned are located on the side-supporting claws I (54) and II (55), so that the side-pressing claws I (63) and the side-supporting claws I (54) are in a closed state and the side-pressing claws II (64) and the side-supporting claws II (55) are in a closed state, clamping and fixing the fruit stalks of the pear tree to be thinned. The image of the pear tree to be thinned is captured and processed by the camera (96) and the signal processor (97), and the signal processor (97) selects the young fruits to be thinned. The laser (9) located on the side support claw I (54) and side support claw II (55) holding the fruit stalk that needs to be thinned is put into working state. The laser (9) burns the fruit stalk that needs to be thinned. After the fruit stalk that needs to be thinned is burned, the laser (9) is put into non-working state. The side pressure claw I (63) and the side support claw I (54) are separated and the side pressure claw II (64) and the side support claw II (55) are separated. The ball head (911) is in an expanded state and the agitating ball (30) is in an initial state.
