The top of the supporting bracket 15 is detachably provided with a seedling storage frame box 16, and the opposite ends of the supporting bracket 15 are fixedly installed with a supporting seat 17 used in conjunction with the seedling storage frame box 16. The upper end of the seedling storage frame box 16 is penetrated by an operating groove 122 for use, and the operating groove 122 is symmetrical. The setting and use of the operating groove 122 provides convenience for the convenient disassembly and assembly of the seedling storage frame box 16.

[0025] By adopting the above technical solution, when in use, the connecting bracket 11 is fixed on the traction equipment, and then the distance between the first planting tube 110 and the second planting tube 115 is adjusted according to the planting needs of the tobacco seedlings to be planted. At this time, the user needs to start the two-way electric push rod 13, so as to drive the two planting brackets 14 to move backwards, and thus gradually increase the distance between the adjacent first planting tubes 110 and the second planting tubes 115, and when the distance between the adjacent first planting tubes 110 moves to an appropriate size, the two-way electric push rod 13 is closed and the two adjustment rockers 121 on either side are rotated in turn, so as to drive the corresponding adjustment handwheel 120 to rotate, and then drive the corresponding double-headed screw 112 to rotate, and further drive the corresponding two second side blocks 113 to move backwards, so that the corresponding two second lifting frames 114 can drive the corresponding two second planting tubes 115 to move backwards, and when the distance between the second planting tube 115 and the corresponding first planting tube 110 is adjusted to an appropriate size, the corresponding adjustment rocker 121 is released. The two workers then sit on the two supporting chairs 17 and put the tobacco seedlings into the first planting tube 110 and the second planting tube 115 on the corresponding side in turn, and drive the corresponding first lifting frame 19 to move up and down in a circular motion through the first electric telescopic rod 18, so that the corresponding second lifting frame 114 can be driven to move up and down in a synchronous manner through the corresponding transverse guide rod 116, and then the first planting tube 110 and the second planting tube 115 can be driven to move up and down in a circular motion, and further the corresponding tobacco seedlings can be driven to move downward and planted in the soil, so that the synchronous planting of six tobacco seedlings at a time can be realized. If there is a shortage of staff, the synchronous planting of three tobacco seedlings at a time can be carried out. At this time, there is no need to start the two-way electric push rod 13 and adjust the distance between the first planting tube 110 and the second planting tube 115 on the corresponding side according to the on-site usage requirements.

[0026] The sample retention mechanism 2 includes a sample retention bracket 21 and an L-shaped side rod 22. The sample retention bracket 21 is fixedly connected to the planting bracket 14, and a driving motor 23 is fixedly installed at the lower end of the sample retention bracket 21. The output end of the driving motor 23 rotates through the sample retention bracket 21 and is fixedly sleeved with a sample retention turntable 24 at its end. The sample retention turntable 24 is provided with a matching placement sink 25, a material passing groove 26 and a material passing sink 27. The placement sink 25 and the material passing groove 26 are staggered, and a sample retention cylinder 28 is detachably provided in the placement sink 25. There are six sample cylinders 28 in total, and they are divided into six colors. A sliding guide hole 29 is opened on the sample holder 21, and a sliding guide rod 210 is slidably inserted in the sliding guide hole 29. The bottom end of the sliding guide rod 210 is fixedly sleeved with a mounting base 211, and a reset spring 212 is fixedly installed on the top of the mounting base 211. The reset spring 212 is movably sleeved on the sliding guide rod 210, and the top of the reset spring 212 is fixedly connected to the sample holder 21. A frustum-shaped hopper 213 is fixedly installed on one side of the mounting base 211, and an L-shaped The side rod 22 is fixedly connected to the lower end of the first planting material tube 110, and the lower end of the L-shaped side rod 22 is fixedly sleeved with a pushing guide plate 214. The L-shaped side rod 22 can be slidably inserted in the frustum-shaped hopper 213, and the pushing guide plate 214 can contact the top of the frustum-shaped hopper 213. The limiting mechanism 3 includes a limiting vertical plate 31, which is fixedly installed at the bottom end of the sample turntable 24, and an L-shaped limiting rod 32 is slidably inserted on the limiting vertical plate 31. One end of the L-shaped limiting rod 32 is fixedly sleeved with an arc-shaped limiting plate 33, and the arc-shaped limiting plate A limiting spring 34 is fixedly installed on one side of the positioning plate 33, and the limiting spring 34 is movably mounted on the L-shaped limiting rod 32, and the end of the limiting spring 34 is fixedly connected to the limiting vertical plate 31.

A limiting recess 215 is provided on the sample cylinder 28, and the end of the L-shaped limiting rod 32 can be slidably inserted in the limiting recess 215, so that the sample cylinder 28 can be stably limited and fixed.

[0027] By adopting the above technical solution, when in use, the first planting material tube 110 will synchronously drive the L-shaped side rod 22 to move downward while moving downward, thereby driving the pushing guide plate 214 to move downward synchronously, and when the pushing guide plate 214 contacts the top of the frustum-shaped hopper 213, the L-shaped side rod 22 will block the bottom of the frustum-shaped hopper 213, and then the pushing guide plate 214 will drive the frustum-shaped hopper 213 to move downward synchronously, thereby driving the mounting base 211 and the sliding guide rod 210 to move downward synchronously and stretch the corresponding composite material. The reset spring 212 is used to pull the corresponding frustum-shaped hopper 213 and the collected soil sample upwards. If the soil sampling operation is not required, the push guide plate 214 will be pushed upwards after the frustum-shaped hopper 213 is reset. The soil in the truncated cone hopper 213 will fall out automatically after the L-shaped side rod 22 is no longer blocked, and if soil sampling is required, the corresponding drive motor 23 is started when the truncated cone hopper 213 is reset, thereby driving the corresponding sample turntable 24 to rotate, and then driving the corresponding three sample cylinders 28 to rotate. When the corresponding sample cylinder 28 is rotated to the bottom of the truncated cone hopper 213, the corresponding drive motor 23 is paused, and then the L-shaped side rod 2 is turned on. The collected soil sample will fall into the corresponding sample cylinder 28 while continuing to move upward and reset. Then, the driving motor 23 will drive the sample turntable 24 to reset. After the use of the planting equipment is finished, the corresponding L-shaped limit rod 32 will be pulled, thereby driving the corresponding arc-shaped limit plate 33 to move, thereby squeezing the corresponding limit spring 34 and completely separating the L-shaped limit rod 32 from the corresponding limit recess 215. Then, the sample cylinder 28 storing the soil sample will be removed and the corresponding soil sample will be studied and sealed.

[0028] The marking mechanism 4 includes a marking bracket 41, the marking bracket 41 is fixedly connected to the planting bracket 14, and a second electric telescopic rod 42 distributed in an array is fixedly installed on the marking bracket 41, the output end of the second electric telescopic rod 42 slides through the marking bracket 41 and is fixedly connected to a pusher horizontal plate 43 at its end, and a pusher vertical plate 44 is fixedly installed on the pusher horizontal plate 43, and a sliding groove 45 distributed in an array is provided at the lower end of the marking bracket 41, and a marking plug-in plate 46 is slidably inserted in the sliding groove 45, and the marking plug-in plate 46 is also divided into six colors, which correspond to the colors of the six sample cylinders 28 one by one, and the pusher vertical plate 44 can contact the marking plug-in plate 46, and a stable socket 47 is provided on one side of the marking bracket 41. The lower end is penetrated by an array of stabilizing through holes 48, and a stabilizing rod 49 is slidably inserted in the stabilizing through holes 48, and the end of the stabilizing rod 49 can be slidably inserted in the stabilizing socket 47, and a stabilizing ring 410 is fixedly sleeved on the stabilizing rod 49, and a stabilizing spring 411 is fixedly installed on one side of the stabilizing ring 410, and the stabilizing spring 411 is movably sleeved on the stabilizing rod 49, and the end of the stabilizing spring 411 is fixedly connected to the benchmarking bracket 41, and the end of the stabilizing rod 49 is fixedly connected to the hemispherical plug 412, and the hemispherical plug 412 can be slidably clamped in the stabilizing socket 47. The setting and use of the hemispherical plug 412 ensures the stable placement of the benchmarking plug plate 46 while providing a guarantee for its normal downward movement under the action of thrust in the later stage.

[0029] By adopting the above technical solution, when in use, the second electric telescopic rod 42 corresponding to the color of the corresponding sample cylinder 28 will be started while the soil sampling operation is being carried out, thereby driving the corresponding pushing horizontal plate 43 to move downward, and then driving the corresponding pushing vertical plate 44 to move downward, and further pushing the corresponding color marking plug-in plate 46 to move downward. At this time, the hemispherical plug 412 will separate from the corresponding stable socket 47 and drive the corresponding stable plug-in rod 49 to move, so that the corresponding stable spring 411 can be squeezed through the stable ring 410, and then the hemispherical plug 412 will squeeze the corresponding marking plug-in plate 46 and slide along the outer wall of the corresponding marking plug-in plate 46, so as to ensure the steady downward movement of the marking plug-in plate 46, until the marking plug-in plate 46 is inserted into the corresponding soil and the pushing vertical plate 44 passes through the corresponding sliding groove 45, so that the corresponding second electric telescopic rod 42 drives the corresponding pushing horizontal plate 43 to reset.

[0030] Working principle: When in use, the connecting bracket 11 is fixed on the traction equipment, and then the distance between the first planting tube 110 and the second planting tube 115 is adjusted according to the planting needs of the tobacco seedlings to be planted. At this time, the user needs to start the two-way electric push rod 13, so as to drive the two planting brackets 14 to move backwards, and then gradually increase the distance between the adjacent first planting tubes 110 and the second planting tubes 115, and when the distance between the adjacent first planting tubes 110 moves to an appropriate size, the two-way electric push rod 13 is closed and the two adjusting rockers 121 on either side are rotated in turn, so as to drive the corresponding adjusting hand wheel 120 to rotate, and then drive the corresponding double-headed screw 112 to rotate, and further drive the corresponding two second side blocks 113 to move backwards, so that the corresponding two second lifting frames 114 can drive the corresponding two second planting tubes 115 to move backwards, and when the distance between the second planting tube 115 and the corresponding first planting tube 110 is adjusted to an appropriate size, the corresponding adjusting rocker is released. 121, then the tobacco seedlings are placed in the two seedling storage frames 16 in turn and the two seedling storage frames 16 are clamped on the two supporting brackets 15 in turn, and then the two staff members sit on the two supporting chairs 17 respectively and put the tobacco seedlings into the first planting material tube 110 and the second planting material tube 115 on the corresponding side in turn, and drive the corresponding first lifting frame 19 to move up and down in a circular reciprocating motion through the first electric telescopic rod 18, so that the corresponding second lifting frame 114 can be driven to move up and down in a synchronous circular reciprocating motion through the corresponding transverse guide rod 116, and then the first planting material tube 110 and the second planting material tube 115 can be driven to move up and down in a circular reciprocating motion, and further the corresponding tobacco seedlings can be driven to move down and planted in the soil, so that the synchronous planting of six tobacco seedlings at a time can be realized. If there is a shortage of staff, the synchronous planting of three tobacco seedlings at a time can be carried out. At this time, there is no need to start the two-way electric push rod 13 and adjust the distance between the first planting material tube 110 and the second planting material tube 115 on the corresponding side according to the on-site use requirements; At the same time, the first planting material tube 110 will synchronously drive the L-shaped side rod 22 to move downward while moving downward, thereby driving the pushing guide plate 214 to move downward synchronously. When the pushing guide plate 214 contacts the top of the frustum-shaped hopper 213, the L-shaped side rod 22 will block the bottom of the frustum-shaped hopper 213, and then the pushing guide plate 214 will drive the frustum-shaped hopper 213 to move downward synchronously, thereby driving the installation base plate 211 and the sliding guide rod 210 to move downward synchronously and stretch the corresponding return spring 212. When the first planting material tube 110 and the second planting material tube 115 move down to the lowest point, the soil in the corresponding planting ground will enter the corresponding conical hopper 213. In addition, when the first planting material tube 110 moves up, it will drive the L-shaped side rod 22 and the pushing guide plate 214 to move up synchronously. At this time, the reset spring 212 will pull the corresponding conical hopper 213 and the collected soil sample to move up synchronously. If there is no need to perform soil sampling operation, the pushing guide plate 214 will separate from the conical hopper 213 after it is reset. , and the L-shaped side rod 22 will no longer block the bottom of the truncated cone hopper 213, and the soil in the truncated cone hopper 213 will automatically fall out. If soil sampling is required, the corresponding drive motor 23 is started when the truncated cone hopper 213 is reset, thereby driving the corresponding sample turntable 24 to rotate, and then driving the corresponding three sample cylinders 28 to rotate. When the corresponding sample cylinder 28 rotates to the bottom of the truncated cone hopper 213, the corresponding drive motor 23 is paused, and then the L-shaped side rod 22 is continued to rotate. The soil sample collected while moving up and resetting will fall into the corresponding sample cylinder 28, and then the driving motor 23 will drive the sample turntable 24 to reset, and after the use of the planting equipment is finished, the corresponding L-shaped limit rod 32 will be pulled, thereby driving the corresponding arc-shaped limit plate 33 to move, and then the corresponding limit spring 34 can be squeezed to completely separate the L-shaped limit rod 32 from the corresponding limit recess 215, and then the sample cylinder 28 storing the soil sample will be removed and the corresponding soil sample will be studied and sealed; During this period, while the soil sampling operation is underway, the second electric telescopic rod 42 corresponding to the color of the sample cylinder 28 will be started, thereby driving the corresponding pushing horizontal plate 43 to move downward, and then driving the corresponding pushing vertical plate 44 to move downward, and further pushing the corresponding color marking plug-in plate 46 to move downward. At this time, the hemispherical plug 412 will separate from the corresponding stable socket 47 and drive the corresponding stable plug-in rod 49 to move, so that the corresponding stable spring 411 can be squeezed through the stable ring 410, and then the hemispherical plug 412 will squeeze the corresponding marking plug-in plate 46 and slide along the outer wall of the corresponding marking plug-in plate 46, so as to ensure the steady downward movement of the marking plug-in plate 46, until the marking plug-in plate 46 is inserted into the corresponding soil and the pushing vertical plate 44 passes through the corresponding sliding groove 45, so that the corresponding second electric telescopic rod 42 drives the corresponding pushing horizontal plate 43 to reset.

[0031] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
