[0028] Specifically, the two groups of duckbill planting mechanisms 10 are mirror image arranged, the conical hopper 102 is arranged to make the seedling axis coincide with the center line of the two duckbill bodies 104 through a guide inclined surface, and the duckbill bodies 104 are provided with polytetrafluoroethylene coatings on the inner and outer sides to reduce the clay adhesion rate.

[0029] Please refer to Figures 2-3 ; The transmission mechanism 20 is symmetrically distributed in two groups, which are respectively arranged at one end of the two groups of duckbill planting mechanisms 10, and is used for driving the duckbill planting mechanism 10 to move, and comprises a protective cover 201, a main pull rod 202 and a secondary pull rod 203 which are respectively hinged to the inner wall of the protective cover 201, a cam 204 which is rotatably installed on the inner wall of the protective cover 201, a connecting rod 205 which is hinged to the surface of the main pull rod 202, and the other end of the connecting rod 205 is hinged to the pin shaft of the cam 204, and the other end of the main pull rod 202 and the secondary pull rod 203 are both fixedly connected to the surface of the supporting frame 101 of the duckbill planting mechanism 10.

[0030] Specifically, when the cam 204 rotates, the connecting rod 205 is driven to move, the main pull rod 202 is pulled by the connecting rod 205, and the secondary pull rod 203 is forced to rotate synchronously, so that the supporting frame 101 is pulled back and forth by the main pull rod 202 and the secondary pull rod 203, and the cam 204 triggers a planting cycle after each rotation.

[0031] The surface of the protective cover 201 is provided with a driving component for driving the two duckbill bodies 104 to open, the driving component comprises a driving rod 206 which is hinged to the inner wall of the protective cover 201, a roller 207 which is rotatably connected to the surface of the driving rod 206, and a first brake cable 209 which is arranged on one side of the driving rod 206.

[0032] One end of the first brake cable 209 is hinged to one end of the driving rod 206, one end of the first brake cable 209 is hinged to the surface of one of the two rotating frames 103, and the adjusting screws at both ends of the first brake cable 209 are respectively fixedly installed on the surface of the protective cover 201 and the other rotating frame 103, the surfaces of the two rotating frames 103 are hinged with a reset spring 208 for driving the two duckbill bodies 104 to close, and the lower surfaces of the two rotating frames 103 are provided with a passage for the orchid seedlings to enter the two duckbill bodies 104.

[0033] Specifically, the roller 207 is a polyurethane-coated steel core structure, the artificial puts the orchid seedlings into the conical hopper 102, the guiding slope of the conical hopper 102 makes the seedlings automatically align the center line, at this time, the duckbill body 104 is in a closed standby state, the cam 204 pushes the connecting rod 205 to make the duckbill planting mechanism 10 move downward as a whole.

[0034] The working principle of the embodiment is as follows: when the cam 204 rotates to drive the duckbill planting mechanism 10 to insert into the ground, the maximum point of the cam 204 contacts the roller 207 at this time, the roller 207 is forced to rotate to drive the driving rod 206 to rotate, the driving rod 206 rotates to drive the first brake cable 209 to work, and the first brake cable 209 transmits the tension to drive the duckbill body 104 to open to the maximum angle, at this time, the orchid seedlings in the two duckbill bodies 104 enter the hole, when the cam 204 continues to rotate to the maximum point to separate from the roller 207, the connecting rod 205 pulls the duckbill planting mechanism 10 to rise and reset, at this time, the reset spring 208 drives the two duckbill bodies 104 to combine, the soil naturally covers the root of the seedling under the gravity of the soil, and then the external soil covering wheel of the machine covers the soil to complete the planting.

[0035] Embodiment two Compared with the first embodiment, another embodiment of the application is as follows: Please refer to Figures 4-7 The irrigation mechanism 30 includes two mounting racks 301 fixedly installed on the external mechanical vehicle body, a valve 302 fixedly installed on the left side of the mounting rack 301 through a bolt, a nozzle 303 installed on the drainage end of the valve 302, and a water inlet pipe 304 installed on the water inlet end of the valve 302.

[0036] The valve 302 includes a valve body 3021, a sealing step formed in the inner wall of the valve body 3021, a valve rod 3022 slidingly fitted in the inner wall of the valve body 3021, a valve core 3023 fixedly installed on one end of the valve rod 3022 for blocking the sealing step, and a compression spring 3024 sleeved on the surface of the valve rod 3022 for driving the valve core 3023 to block the sealing step. The other ends of the two water inlet pipes 304 of the irrigation mechanism 30 are connected with an external water tank, and the external water tank is installed on the external mechanical vehicle body.

[0037] Specifically, the valve core 3023 adopts a rubber sealing head to form a composite seal with the metal sealing step, the mounting rack 301 is vertically fixed on the two sides of the external mechanical vehicle body through a bolt to ensure that the bearing surface is completely matched with the vehicle body frame, and the two mounting racks 301 are collinear with the duckbill body 104 and located behind the external soil covering wheel. The valve 302 is fixed on the left side of the mounting rack 301 through a flange connection, the water inlet pipe 304 is connected with the external water tank through a high-pressure hose, an O-shaped sealing ring is additionally installed at the joint to prevent leakage, and the compression spring 3024 pushes the valve rod 3022 to move right in the initial state to press the valve core 3023 against the sealing step to form a sealing surface, at this time, the system waterway is cut off.

[0038] The drive rod 206 is provided with a pulling component for opening and closing the valve core 3023, which is composed of the second brake cable 305 and the pulling frame 306 fixedly installed on the left side of the valve body 3021. The pulling frame 306 is provided with a through hole on the surface, one end of the second brake cable 305 is hingedly connected with one side of the drive rod 206, one end of the second brake cable 305 is hingedly connected with one end of the valve rod 3022, and the adjusting screws at the two ends of the second brake cable 305 are fixedly installed on the surface of the protective cover 201 and the inner wall of the through hole.

[0039] Specifically, when the cam 204 contacts the roller 207 on the drive rod 206 at the maximum point, the drive rod 206 is forced to rise and support the duckbill body 104, at this time, the drive rod 206 rising drives the second brake cable 305 to act, so that the second brake cable 305 rope can pull the valve rod 3022 to move left, overcome the spring force to make the valve core 3023 separate from the sealing step, and the water flows into the nozzle 303 through the water inlet pipe 304 to spray to irrigate the orchid after planting. When the cam 204 is separated from the drive rod 206 at the maximum point, the second brake cable 305 is disabled, and the compression spring 3024 automatically resets the valve 302 to avoid water waste.

[0040] The working principle of the embodiment is as follows: through the transmission of the cam 204-connection rod 205-main pull rod 202 and auxiliary pull rod 203, the rotary motion is converted into reciprocating opening and closing action. When the cam 204 rotates, the cam 204 contacts the roller 207 at the maximum point and forces the drive rod 206 to rotate, which can support the duckbill body 104 in cooperation with the first brake cable 209. At the same time, when the drive rod 206 rotates, the second brake cable 305 works synchronously, which pulls the valve rod 3022 to drive the water in the valve body 3021 to spray from the nozzle 303 for irrigation. Through the synchronous driving of the drive rod 206 to drive the first brake cable 209 and the second brake cable 305, the synchronization of the duckbill opening and irrigation is realized.

[0041] Embodiment three Compared with the first embodiment, another embodiment of the application is as follows: Please pay attention to Figures 8-11 The distance adjusting mechanism 40 includes a guide frame 401, a bidirectional ball screw 402 rotatably connected to the inner wall of the guide frame 401, two nut seats 403 screwingly transmitted on the surface of the bidirectional ball screw 402, and a hydraulic motor 404 fixedly installed on one end of the guide frame 401 for driving the bidirectional ball screw 402 to rotate. The two nut seats 403 are fixedly connected with the support frames 101 on the two duckbill planting mechanisms 10, respectively.

[0042] Specifically, when the hydraulic motor 404 is driven, the bidirectional ball screw 402 can be driven to rotate, and the bidirectional ball screw 402 and the two nut seats 403 are in screw transmission, so that the two nut seats 403 are driven to move close to or away from each other, and the distance between the two duckbill planting mechanisms 10 can be adjusted. Compared with the traditional manual bolt positioning, the adjustment efficiency is greatly improved, and the density requirements of different types of orchids in the growth period are met.

[0043] The driving mechanism 50 comprises a sliding rail 501 fixedly installed on the external mechanical vehicle body, a transmission shaft 502 rotatably installed on the external mechanical vehicle body, sliding plates 503 symmetrically and slidingly fitted in the inner wall of the sliding rail 501, spline shafts 504 fixedly installed on the opposite surfaces of the two sliding plates 503 respectively, spline sleeves 505 slidingly fitted on the surfaces of the spline shafts 504, first synchronous wheels 506 fixedly installed on the surfaces of the spline sleeves 505, second synchronous wheels 507 symmetrically and fixedly installed on the transmission shaft 502, two first synchronous wheels 506 in transmission connection with two second synchronous wheels 507 through a synchronous belt 508, and one end of each of the two spline shafts 504 in fixed connection with the installation shaft of the cam 204 of each of the two transmission mechanisms 20. The spline sleeve 505 is rotatably installed on the external mechanical vehicle body through a bearing.

[0044] Specifically, the cooperation of the sliding rail 501 and the sliding plate 503 can guide the movement track of the duckbill planting mechanism 10, share the stress of the guide frame 401, and improve the stability of the movement of the duckbill planting mechanism 10. The transmission shaft 502 is connected with the power source on the external mechanical vehicle body. When the external power source drives the transmission shaft 502 to rotate, the two second synchronous wheels 507 on the transmission shaft 502 rotate synchronously. The rotation of the two first synchronous wheels 506 can be driven through the transmission of the synchronous belt 508. The rotation of the cam 204 can be driven through the cooperation of the spline shaft 504 and the spline sleeve 505, so that the transmission of power can be realized.

[0045] The working principle of the embodiment is that when the distance adjusting mechanism 40 adjusts the distance between the two duckbill planting mechanisms 10, the spline shaft 504 can slide in the spline sleeve 505, and the spline sleeve 505 is stationary. When the spline shaft 504 slides in the axial direction, the torque is still transmitted, so that interference is avoided.

[0046] Working principle: Power input: The external mechanical power drives the transmission shaft 502 to rotate, and the power is transmitted to the spline sleeve 505 through the second synchronous wheel 507, the synchronous belt 508 and the first synchronous wheel 506.

[0050] ‌Reset and close: After the maximum point of cam 204 is separated from roller 207, reset spring 208 pulls rotating frame 103 to close duckbill body 104, and connecting rod 205 pulls duckbill planting mechanism 10 to rise, covering the seedling roots with soil.

[0051] ‌Synchronous irrigation ‌Valve 302 linkage: When drive rod 206 rotates, it synchronously pulls second brake cable 305, overcomes the resistance of compression spring 3024 to pull valve rod 3022, and makes valve core 3023 separate from the sealing step.

[0052] ‌Water injection: High-pressure water flows through water inlet pipe 304, valve body 3021, and is sprayed from nozzle 303, irrigating the newly planted seedlings.

[0053] ‌Automatic valve closing: After cam 204 is separated from roller 207, compression spring 3024 pushes valve core 3023 to reset the water path, avoiding water waste.

[0054] ‌Spacing adjustment Starting hydraulic motor 404 drives bidirectional ball screw 402 to rotate, two nut seats 403 move in opposite directions along bidirectional ball screw 402, driving support frame 101 and the entire duckbill planting mechanism 10 to move closer or farther away. When adjusting the spacing, spline shaft 504 slides axially in spline sleeve 505.

[0055] ‌Work flow Manually place the seedlings into conical hopper 102, and the guide slope automatically aligns the seedlings with the center line of the duckbill; Cam 204 rotates to drive duckbill planting mechanism 10 to insert into the soil. When the high point of cam 204 lifts drive rod 206, duckbill body 104 opens to sow the seedlings, and valve 302 opens to irrigate. ‌Reset stage: When cam 204 is separated from the high point, reset spring 208 closes the duckbill, and compression spring 3024 closes valve 302.
