Technical Field

Therefore, plant root secretions are an important part of plant microecology research, so extraction devices are needed to extract plant secretions.

A shielding mechanism is installed at the center of the upper surface, and the shielding mechanism and the semicircular cover 3 are combined into a darkroom structure, and multiple extraction mechanisms are installed side by side at intervals on one side of the shielding mechanism. The shielding mechanism cooperates with the semicircular cover 3 to complete the secretion extraction of plants in the multiple extraction mechanisms. At the same time, a feeding mechanism is installed on the other side of the shielding mechanism. The feeding mechanism is used to complete the feeding action for the multiple extraction mechanisms. A trigger mechanism is added to the shielding mechanism, and the trigger mechanism cooperates with the semicircular cover 3 to complete the dynamic positioning operation of the multiple extraction mechanisms through the trigger mechanism.

[0042] Among them, electrical components such as the rotating motor 6 and the electric cylinder 28 are connected to switches through wires, and the switches are electrically connected to a controller. The specific structure of the controller is not limited. An absolute encoder is installed on the rotating motor 6 to accurately position the rotating motor 6.

[0043] Embodiment 2: Based on the shielding mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the shielding mechanism.

[0044] like Figures 4 to 10As shown, the shielding mechanism includes a shielding plate 5 that is detachably fixedly installed at the center of the turntable 2, and the two ends of the shielding plate 5 are separated from the inner wall of the semicircular cover 3 and do not contact each other. A dark room is formed by combining the shielding plate 5, the semicircular cover 3 and the telescopic plate 11. The shielding plate 5 is made of a light-shielding material, and the top of the shielding plate 5 is rotatably connected to the center of the semicircular cover 3. A rotating motor 6 is hidden and installed on the base 1, and the output end of the rotating motor 6 is transmission-connected to the center of the lower surface of the turntable 2. A circular track 7 is formed between the ring member 4 and the turntable 2, and two storage areas 8 are symmetrically provided on the ring member 4, and the storage areas 8 are interconnected with the circular track 7. The two storage areas 8 correspond to the two ends of the semicircular cover 3, and the two side walls of each storage area 8 are provided with inclined surfaces 9, which are guided by the inclined surfaces 9 and the circular track 7. Sliding areas 10 are recessed inwardly on both sides of the shielding plate 5, and a telescopic plate 11 is slidably installed in the sliding area 10. In order to improve the stability of the telescopic plate 11 in telescoping, The semicircular guide ring 43 is fixed on the top of the semicircular cover 3, and a plurality of guiding balls can be hidden on the surface of the semicircular guide ring 43, and guiding inclined areas are provided at the head and tail of the semicircular guide ring 43, and the guiding inclined areas can guide the telescopic plate 11, and the two ends of the semicircular guide ring 43 cooperate with the two storage areas 8. When the telescopic plate 11 moves into the two storage areas 8, the telescopic plate 11 is separated from the semicircular guide ring 43. The design of the semicircular guide ring 43 can complete the extrusion guidance of the top of the telescopic plate 11, so that the telescopic plate 11 is stably separated from the inner wall of the semicircular cover 3, and the bottom of the telescopic plate 11 is in sliding contact with the annular member 4, a sealing gasket is installed on the telescopic plate 11 toward the inner wall of the semicircular cover 3, and a plurality of push springs 12 are installed between the telescopic plate 11 and the sliding area 10, and two sliding members 13 are symmetrically slidably engaged in the annular track 7, and the two sliding members 13 are respectively detachably fixedly connected to the two ends of the bottom of the shielding plate 5;

[0045] It is worth mentioning that: when extracting: by providing a shielding mechanism, the plant body 24 is placed in the nutrient solution in the extraction tube 17, and the rotating motor 6 is started to drive the turntable 2 and the shielding plate 5 to rotate, so that multiple extraction tubes 17 are transferred to the semicircular cover 3, so as to provide a dark room environment for the plant bodies 24 in the multiple extraction tubes 17, which is conducive to the extraction of secretions of the plant body 24. At the same time, there is no need to repeatedly transfer the position of the extraction equipment. The extraction progress can be controlled by rotating the motor 6, and the station conversion of the rotating motor 6 makes the overall extraction work time-saving and labor-saving, and the secretion information of the plant body 24 can be quickly obtained. When the two ends of the shielding plate 5 correspond to the two ends of the semicircular cover 3, at this time, under the action of the pushing spring 12, the telescopic plate 11 is driven to extend in the sliding area 10, and the telescopic arm 14 is extended in the sliding member 13, so that the guide wheel 15 is in contact with the storage area 8, so that the shielding plate 5 can be with the semicircular cover 3. The circular cover 3 is in close contact, which can ensure the good light shielding property of the semicircular cover 3 and avoid the problem of light leakage. When the shielding plate 5 rotates, it is guided by the inclined surface 9 of the storage area 8, so that the telescopic arm 14 is retracted into the sliding member 13 again. At the same time, the telescopic plate 11 is retracted in the sliding area 10 and compresses the push spring 12, and then the telescopic plate 11 is separated from the semicircular cover 3. Under the restriction of the circular track 7, the shielding plate 5 follows the sliding member 13 to complete the rotation, so that the shielding plate 5 and the semicircular cover 3 rotate in a separated state, reducing the friction and making the operation of the extraction mechanism smoother. When the secretion extraction is completed, the multiple extraction tubes 17 are transferred to the outside of the semicircular cover 3 by rotating the motor 6. At this time, the secretion liquid is collected and transferred through the lead-out pipes 19 on each extraction tube 17, and the secretion is obtained after subsequent concentration treatment. Repeating the above actions can complete multiple extractions, thereby improving the extraction efficiency.

[0046] Among them, a telescopic arm 14 is evenly and slidably installed in each sliding member 13, and a guide wheel 15 is rotatably installed at the front end of the telescopic arm 14. The guide wheel 15 is in rotational contact with the storage area 8, and the telescopic arm 14 is detachably and fixedly connected with the telescopic plate 11. When the telescopic arm 14 is extended to the storage area 8, the telescopic plate 11 on the shielding plate 5 extends out to complete the blocking of the semicircular cover 3. When the telescopic arm 14 is misaligned with the storage area 8, the telescopic plate 11 on the shielding plate 5 contracts and separates from the semicircular cover 3 to complete the avoidance.

[0047] In the embodiment of the present invention, each extraction mechanism includes a mounting seat 16 that can be detachably mounted on one side of the shielding plate 5, and an extraction pipe 17 is slidably penetrated on the mounting seat 16. The top of the extraction pipe 17 is open, and a through hole that cooperates with the extraction pipe 17 is penetrated through the shielding plate 5. An inlet pipe 18 is connected to one side of the bottom of the extraction pipe 17, and a control valve for controlling the on-off of the inlet pipe 18 is installed at the end of the inlet pipe 18. An outlet pipe 19 is connected to the other side of the bottom of the extraction pipe 17, and a control valve for controlling the on-off of the outlet pipe 19 is installed at the end of the outlet pipe 19. A limiting groove 20 is recessed inwardly at the top of the seat 16, and a limiting plate 21 can be detachably installed in the limiting groove 20. The limiting plate 21 is fixedly sleeved on the outside of the extraction tube 17, and a positioning hole 22 is opened on one side of the limiting plate 21. A limiting ring 23 is detachably installed on the top of the extraction tube 17, and a plant body 24 is installed on the limiting ring 23. The plant body 24 extends into the extraction tube 17 accordingly. The limiting ring 23 is used to complete the limiting fixation of the plant body 24, and the limiting ring 23 and the extraction tube 17 are specifically detachably connected by means of a lock buckle, a thread, etc.;

[0048] In the embodiment of the present invention, the feeding mechanism includes a barrel 25 installed on one side of the upper surface of the turntable 2, a feed port is installed on the top of the barrel 25, an extrusion chamber 26 is installed on the upper surface of the turntable 2 on one side of the barrel 25, the top of the extrusion chamber 26 is open, a piston 27 is installed in the extrusion chamber 26 in a sliding seal, and an electric cylinder 28 is installed on one side of the baffle plate 5 through a bracket, the output end of the electric cylinder 28 is connected to the piston 27 by transmission, an input pipe 29 is installed on one side of the bottom of the extrusion chamber 26, a No. 1 one-way valve for introducing liquid into the extrusion chamber 26 in one direction is installed at the end of the input pipe 29, and the input pipe 29 is connected to the barrel 25 through a pipeline, and the bottom of the extrusion chamber 26 is connected to the piston 27 by a piston 27. The other side of the part is connected with an output pipe 30, and a No. 2 one-way valve for leading the liquid out of the extrusion chamber 26 in one direction is installed at the end of the output pipe 30. A main pipeline 31 is installed on one side of the baffle plate 5, and one side of the main pipeline 31 is connected with the output pipe 30 through a pipeline. A plurality of branch pipes 32 are connected and installed on the main pipeline 31, and manual valves for controlling the on-off of the plurality of branch pipes 32 are installed at the ends of the plurality of branch pipes 32. The plurality of branch pipes 32 are respectively connected with the introduction pipe 18 through spring tubes, and the connection between the plurality of branch pipes 32 and the introduction pipe 18 is completed by a quick-release joint. Specifically, a male plug is installed on the introduction pipe 18, and a female plug is installed on the spring tube of the branch pipe 32, and the quick connection work is completed by the male plug and the female plug;

[0049] It is worth noting that: when loading: by providing a feeding mechanism, after a single extraction is completed, it is only necessary to control the electric cylinder 28 to move upward, pull the piston 27 to move upward in the extrusion chamber 26 to complete the suction, and suck the nutrient solution in the barrel 25 into the extrusion chamber 26 through the input pipe 29, and then control the electric cylinder 28 to move downward, push the piston 27 to move downward in the extrusion chamber 26 to complete the pushing, and push the nutrient solution into the main pipeline 31 through the output pipe 30, and then send the nutrient solution into the multiple extraction tubes 17 through multiple branch pipes 32 and the introduction pipe 18 to wait for extraction, thereby reducing the workload of manual feeding, making the overall extraction work efficient and convenient, and facilitating technicians to quickly complete multiple extractions. The work enriches the secretion data and is conducive to the research and analysis of the plant body 24.

[0050] Embodiment 3: Based on the trigger mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the trigger mechanism.

[0051] like Figures 11 to 14 As shown, the trigger mechanism includes a trigger chamber 33 installed on one side of the shielding plate 5 through a bracket. The trigger chamber 33 is arranged close to one side of the extraction mechanism. A certain amount of gas is injected into the trigger chamber 33 to facilitate the subsequent triggering and pushing work. The top of the trigger chamber 33 is open in design. A piston 34 is slidably installed in the trigger chamber 33. A trigger rod 35 is installed on the top of the piston 34. A guide plate for guiding the trigger rod 35 is installed on the shielding plate 5. A limiting track for limiting the trigger rod 35 is provided on the guide plate, so that the trigger rod 35 can move up and down stably to avoid deviation. The stopper 34 is used to limit the stopper ring. A spring 36 is installed between the bottom of the piston 34 and the trigger chamber 33. The spring 36 is used to push the piston 34 out of the trigger chamber 33. Two intercommunication pipes 37 are symmetrically connected and installed at the bottom of the trigger chamber 33. The two intercommunication pipes 37 extend to the back of the shielding plate 5 through pipelines. A trigger 38 is installed on the top of the trigger rod 35. A plurality of linkage members 39 are distributed on the other side of the shielding plate 5. The plurality of linkage members 39 are arranged in cooperation with a plurality of extraction mechanisms. The plurality of linkage members 39 are controlled by the trigger chamber 33. The plurality of linkage members 39 are respectively connected with the two intercommunication pipes 37 through pipelines.

[0052] It is worth mentioning that when the extraction mechanism is positioned: by providing a trigger mechanism, the insertion rods 395 on the multiple linkage members 39 slide through the baffle plate 5 and the mounting seat 16 accordingly. Through the design of the insertion rod 395, the internal reinforcement of the mounting seat 16 can be completed, the bearing capacity of the mounting seat 16 is improved, and the stable operation of the mounting seat 16 is ensured. When the extraction mechanism is outside the semicircular cover 3, the trigger member 38 is in a reset state, the No. 1 piston member 34 moves up and resets, the No. 2 piston member 393 shrinks and resets, and the insertion rod 395 is hidden in the mounting seat 16, so that the extraction tube 17 can be drawn out from the limiting groove 20 of the mounting seat 16 through the limiting plate 21, which is convenient for technicians to replace and clean and maintain, ensuring the convenience of equipment operation and reducing the difficulty of installation and disassembly. When multiple extraction mechanisms are transferred to the semicircular cover 3, in the path of rotation of the baffle plate 5, the trigger member 38 contacts the top of the semicircular cover 3, and under the guidance of the guiding slope 382 of the arc block 381, the trigger member 38 gradually moves with the semicircular cover 3. The top of the circular cover 3 fits together, so that the trigger member 38 and the No. 1 piston member 34 move downward synchronously, compressing the No. 1 spring 36, and squeezing the gas in the No. 1 trigger chamber 33 to multiple No. 2 trigger chambers 391 through the interconnecting pipe 37, so that the No. 2 piston member 393 overcomes the No. 2 spring 394 to move forward, and synchronously drives the insertion rod 395 to move forward and insert into the corresponding positioning hole 22 to complete the locking action, so that each extraction tube 17 is in a stable state in the semicircular cover 3, avoiding the problem of shaking and displacement, and providing assistance for the secretion extraction of the plant body 24. At the same time, with the assistance of the roller 383, the trigger member 38 can be rotated and guided by the roller 383, so that the trigger member 38 and the semicircular cover 3 are smoothly contacted to complete the triggering, reducing friction loss. Later, when the shielding plate 5 drives multiple extraction tubes 17 to move to the outside of the semicircular cover 3, the initial trigger member 38 is reset and extended by the push of the No. 1 spring 36, waiting for the next trigger locking work, and then completing the dynamic positioning operation of the extraction tube 17;

[0053] In the embodiment of the present invention, each linkage member 39 includes a No. 2 trigger chamber 391, which is detachably fixed to one side of the baffle plate 5. An air pipe 392 is installed at the tail of the No. 2 trigger chamber 391, and the air pipe 392 is connected to the interconnecting pipe 37 through a pipeline.
