The area of ​​the test farmland is small, and the existing automatic sowing equipment cannot adapt, resulting in the precision transplanting technology mainly relying on manual operation. Manual transplanting is inefficient and labor-intensive, and it is easy to affect the precise position of the seedlings in the test area during the test, further extending the test period and increasing errors. In addition, the zoning control of the test area also increases the difficulty and complexity of the operation.

DETAILED DESCRIPTION

[0019] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0021] Reference below Figure 1 to Figure 11 A rice precision seeding and transplanting machine according to an embodiment of the present application is described. Figure 1~Figure 3As shown, the present application provides a rice precision seeding and transplanting machine, including a mobile seat 1, a transplanting mechanism 2 and a limiting mechanism 6; illustratively, the mobile seat 1 is arranged on both sides of the test farmland along the length direction of the test farmland, and the mobile seat 1 spans the test farmland, and universal wheels 11 are provided at the bottom of both ends of the mobile seat 1, and a transplanting space 12 is provided in the middle of the mobile seat 1 and along its own length direction. Exemplarily, the universal wheel 11 is a self-locking universal wheel 11, which can be self-locked after moving to the target position. Further, a moving track is provided on both sides of the test farmland and along the length direction of the test farmland, and the universal wheel 11 is rolled in the moving track, so that the universal wheel 11 can move along a predetermined route without being easily deviated. Exemplarily, a sidewalk board for test personnel to walk on is provided on the mobile seat 1, and the length direction of the sidewalk board is consistent with the length direction of the mobile seat 1, so that the test personnel can walk on the mobile seat 1.

[0022] At the same time, the transplanting mechanism 2 includes a moving component 3, a driving component 4 and a quantitative separation component 5. The moving component 3 can move along the length direction of the moving seat 1, the driving component 4 is installed on the moving component 3, and the quantitative separation component 5 is installed on the driving component 4, wherein the driving component 4 is used to drive the quantitative separation component 5 to move in the vertical direction of the transplanting space 12. The quantitative separation component 5 can form a rectangular test soil area with the silt in the test area to be transplanted after partially inserting itself into the test farmland, and lift it up or lower it vertically, so that the rectangular test soil area is temporarily separated from the test farmland, and a rectangular mud pit is formed in the test farmland; the quantitative separation component 5 can control the thickness of the rectangular test soil area, so that the thickness of the separated rectangular test soil area is roughly the same as the target transplanting depth.

[0023] Furthermore, a limiting mechanism 6 is installed on the moving component 3. The limiting mechanism 6 is used to limit the rectangular test soil area after the quantitative separation component 5 is partially inserted into the test farmland, so that the rectangular mud pit remains in a rectangular state after the rectangular test soil area is lifted vertically upward.

[0024] On this basis, when it is necessary to carry out precision sowing and transplanting of rice seedlings, the test personnel first walk onto the sidewalk board, then start the moving component 3 to move the quantitative separation component 5 to just above the target test area, and then start the driving component 4 to move the quantitative separation component 5 vertically downward, so that part of the quantitative separation component 5 is inserted into the mud of the test farmland, and the insertion depth of the quantitative separation component 5 is controlled, so that the test personnel stop after the quantitative separation component 5 is inserted to a preset depth, and then start the limiting mechanism 6 to limit the surrounding area of ​​the rectangular test soil area, so that the rectangular mud pit remains in a rectangular state after the rectangular test soil area is lifted vertically upward.

[0025] Then start the quantitative separation component 5, so that the quantitative separation component 5 forms a rectangular test soil area with the silt in the test area to be transplanted and lifts it vertically upward. Since the insertion depth of the quantitative separation component 5 is controlled, the soil in the rectangular test soil area is the depth of the test seedlings during the research and development test. At this time, the test personnel can stand on the sidewalk and directly insert the seedlings vertically into the rectangular test soil area. After the corresponding number of test seedlings are inserted into the rectangular test soil area, the quantitative separation component 5 is moved down by the driving component 4 to reach the previous depth position again, and then the quantitative separation component 5 is lowered, and then the rectangular test soil area with the test seedlings is lowered to the initial position, and then the quantitative separation component 5 that has been lowered is slowly lifted, and the limit mechanism 6 is lifted at the same time, so that the rectangular test soil area with the seedlings is returned to the initial rectangular mud pit of the test farmland.

[0026] In this way, the test personnel do not need to go down to the test farmland to bend down and plant the seedlings, and they no longer need to measure the depth of the seedlings one by one when planting. There is also no need to worry about the test personnel going down to the test farmland affecting the planting position of the seedlings. This greatly improves the efficiency and reliability of the test seedling planting, and also greatly reduces the labor intensity of the test personnel.

[0027] It is worth noting that in this application, silt refers to soil with moisture, which is the basis for growing rice.

[0028] In some embodiments, Figure 2 , Figure 3 as well as Figure 4 As shown, the moving assembly 3 includes a rodless cylinder 31, a moving plate 32, a guide rail 33 and a guide block 34. The rodless cylinder 31 is arranged on one side of the transplanting space 12 along the length direction of the moving seat 1, and the guide rail 33 is arranged on the other side of the transplanting space 12 along the length direction of the moving seat 1, and the length direction of the rodless cylinder 31 is consistent with the length direction of the guide rail 33. The moving plate 32 is arranged on the moving piston of the rodless cylinder 31, and the guide block 34 is slidably arranged in the guide rail 33. The driving assembly 4 is arranged between the guide block 34 and the moving plate 32. In this way, when the rodless cylinder 31 is started, when the rodless cylinder 31 drives the moving plate 32 to move, the driving assembly 4 can be driven to move synchronously, so that the position of the transplanting mechanism 2 above the experimental farmland can be conveniently adjusted; at the same time, the setting of the guide rail 33 and the guide block 34 makes the position adjustment of the drive more stable. Exemplarily, a guide bar groove is opened on the guide rail 33 along its own length direction, and the guide block 34 is slidably inserted in the guide bar groove.

[0029] In some embodiments, Figure 2 , Figure 3 as well as Figure 4As shown, the driving component 4 includes a lifting member 41 and a guide member 42. The lifting member 41 is arranged on the movable plate 32, and the guide member 42 is arranged on the guide block 34. The lifting member 41 is used to drive the quantitative separation component 5 to move in the vertical direction, and the guide member 42 is used to vertically guide the movement of the quantitative separation component 5 in the vertical direction.

[0030] Exemplarily, the lifting member 41 includes a mounting seat 411, an L-shaped plate 412, a rotating motor 413, a threaded rod 414, a threaded sleeve 415 and a first connecting rod 416. The mounting seat 411 is arranged on the upper plate surface of the moving plate 32, the L-shaped plate 412 is vertically arranged on the mounting seat 411, the threaded rod 414 is vertically rotatably arranged between the L-shaped plate 412 and the mounting seat 411, the interior of the mounting seat 411 is hollow, the rotating motor 413 is installed in the mounting seat 411, and the rotating motor 415 is arranged on the upper plate surface of the moving plate 32. The output shaft of 13 is coaxially connected with one end of the threaded rod 414 located in the mounting seat 411, the threaded sleeve 415 is threadedly sleeved on the threaded rod 414, one end of the first connecting rod 416 is connected to the outer wall of the threaded sleeve 415, and the other end is connected to the quantitative separation component 5, a vertical groove 4121 is opened on the vertical plate surface of the L-shaped plate 412, and a sliding block 4151 is provided on the outer wall of the threaded sleeve 415 away from the first connecting rod 416, and the sliding block 4151 is slidably inserted in the vertical groove 4121.

[0031] Exemplarily, the guide member 42 includes a guide column 421, a guide cylinder 422 and a second connecting rod 423, the guide column 421 is vertically arranged on the guide block 34, the guide cylinder 422 is slidably sleeved on the guide column 421, one end of the second connecting rod 423 is connected to the outer wall of the guide cylinder 422, and the other end is laterally connected to the quantitative separation component 5.

[0032] With such an arrangement, the rotating motor 413 is started, and the rotating motor 413 drives the threaded rod 414 to rotate. Due to the restrictions of the vertical groove 4121 and the sliding block 4151, the threaded sleeve 415 cannot rotate on its own, so it will move in the length direction of the threaded rod 414, and then drive the quantitative separation component 5 to move in the vertical direction; at this time, the arrangement of the guide cylinder 422 and the guide column 421 can play a role of guidance and support, so that the quantitative separation component 5 can move more stably in the vertical direction.

[0033] In some embodiments, in combination Figure 2 , Figure 3 as well as Figure 5 The quantitative separation component 5 includes a rectangular quantitative frame 51, an insert 52, a push-pull member 53 and a transverse partition 54. The rectangular quantitative frame 51 is arranged between the driving components 4, and the driving component 4 is used to drive the rectangular quantitative frame 51 to move in the vertical direction of the transplanting space 12. The insert 52 is arranged on the lower end wall of the rectangular quantitative frame 51 and is used to guide the rectangular quantitative frame 51 to be inserted into the silt of the experimental farmland.

[0034] At the same time, the transverse partition 54 is movably arranged in the rectangular quantitative frame 51, the push-pull member 53 is arranged between the rectangular quantitative frame 51 and the driving assembly 4, and the transverse partition 54 has a switchable first state and a second state under the action of the push-pull member 53; wherein, when the transverse partition 54 is in the first state, the lower end of the rectangular quantitative frame 51 is open, and when the transverse partition 54 is in the second state, the rectangular quantitative frame 51 closes its lower end opening laterally under the action of the transverse partition 54 and separates part of the silt from the test area to be transplanted in the test farmland, so that a rectangular test soil area is formed in the rectangular quantitative frame 51.

[0035] Exemplarily, the rectangular quantitative frame 51 is composed of two long plates 511 and two short plates 512, and the two short plates 512 are vertically arranged between the two long plates 511 to form a rectangular space for accommodating the rectangular test soil area, and the lower ends of the long plates 511 and the short plates 512 are arranged to be flush, and the height of the short plates 512 is greater than the maximum insertion depth of the test seedlings during the transplanting test; further, the insert 52 includes a cutting strip, and the cutting strip is provided at the lower ends of the two long plates 511 and the two short plates 512, and the cutting strip is adapted to the length of the lower end of the corresponding long plate 511 or the short plate 512, and the cross-sectional shape of the cutting strip is three The cuttings are angular, and the first side surfaces of the cuttings corresponding to the long plate body 511 and the short plate body 512 are in the same plane in the vertical direction as the inner plate surfaces of the long plate body 511 and the short plate body 512; further, the second side surfaces of the cuttings are in contact with the bottom surfaces of the long plate body 511 and the short plate body 512, and the width of the second side surfaces of the cuttings is the same as the width of the lower ends of the corresponding long plate body 511 and the short plate body 512; illustratively, the third side surfaces of the cuttings are inclined, and the third side surfaces gradually extend from bottom to top in a direction away from the rectangular space, so that the cuttings can guide the silt around the test area to be transplanted to deviate away from the test area to be transplanted during the vertical downward insertion process.

[0036] For example, refer to Figure 5 , Figure 6 as well as Figure 7A group of transverse partitions 54 are symmetrically arranged in the two long plates 511, respectively. The transverse partitions 54 include a polytetrafluoroethylene film 541, a round rod 542 and a magnet strip 543. A plurality of round rods 542 are arranged side by side, and adjacent round rods 542 are hinged to each other. The magnet strip 543 is arranged at the outermost ends of the plurality of side-by-side round rods 542. The polytetrafluoroethylene film 541 sealing sleeve is arranged on the periphery of the magnet strip 543 and the plurality of round rods 542. Further, a sliding cavity 7 for sliding the transverse partition 54 is opened inside the long plate 511. The sliding cavity 7 includes a vertical cavity 71, an arc cavity 72 and a transverse cavity 73. The vertical cavity 71 is vertically arranged in the long plate 511 and one end away from the arc cavity 72 passes through the top wall of the long plate 511 upwardly.

One end of the long plate body 511 away from the arc-shaped cavity 72 horizontally penetrates the side wall of the long plate body 511, and the arc-shaped cavity 72 is smoothly connected between the vertical cavity 71 and the transverse cavity 73. Under the guidance of the arc-shaped cavity 72, when the transverse partition 54 moves from the vertical cavity 71 toward the transverse cavity 73, the transverse partition 54 gradually switches from vertical extension to horizontal extension, so that the transverse partition 54 switches from the first state to the second state; further, the front end of the magnet strip 543 facing away from the round rod 542 is provided with an extrusion slope, and on the two opposite magnet strips 543, the extrusion slope on one magnet strip 543 is inclined toward, and the extrusion slope on the other magnet strip 543 is inclined downward. When the two opposite magnet strips 543 are close to each other until they are in contact, the two extrusion slopes are also in contact.

[0037] Exemplary, combined Figure 4 , Figure 5 as well as Figure 8 A bearing groove 5121 is horizontally provided on the inner plate surface near the lower end of the short plate body 512. The bearing groove 5121 is used for the end of the transverse partition 54 to be inserted and slide, and the bearing groove 5121 is connected to the transverse cavity 73; a lead-out groove 5122 is horizontally provided on the inner plate surface near the lower end of the short plate body 512. The lead-out groove 5122 is connected to the bearing groove 5121, and both end surfaces of the lead-out groove 5122 are inclined surfaces, so that when there is sludge remaining in the bearing groove 5121, the sludge remaining in the bearing groove 5121 is pushed from the bearing groove 5121 to the lead-out groove 5122 by the extrusion force generated when the transverse partition 54 slides in the bearing groove 5121, and the extrusion inclined surface can push part of the sludge located at the moving front end of the transverse partition 54 upward or downward in the process of the two groups of transverse partitions 54 approaching each other horizontally. Further, the opposite surfaces of the two magnet strips 543 are adsorption surfaces.

[0038] Exemplary, combined Figure 2 , Figure 3The push-pull member 53 includes a first cylinder 531 and a transverse connecting plate 532. The first cylinder 531 is installed on the first connecting rod 416. The piston rod of the first cylinder 531 extends vertically upward. The transverse connecting plate 532 is horizontally arranged on the top of the piston rod of the first cylinder 531, and the tops of the two groups of transverse partitions 54 are connected to the bottoms of the transverse connecting plates 532. During the vertical downward movement of the transverse connecting plates 532, the transverse partitions 54 can be pushed to gradually switch from the first state to the second state, and during the vertical upward movement, the transverse partitions 54 can be pushed to gradually switch from the second state to the first state.

[0039] On this basis, when the rectangular quantitative frame 51 is directly above the test area to be transplanted, the rotating motor 413 is started to move the rectangular quantitative frame 51 vertically downward. In this process, the cuttings will be inserted into the mud in advance. Due to the shape characteristics of the cuttings, the cuttings can easily break the mud and are not easy to squeeze the mud on one side of the rectangular space, so that the rectangular test soil area formed by the mud in the rectangular space has a more complete appearance and is more in line with the transplanting area required by the test. After the cuttings are fully inserted, the rectangular quantitative frame 51 is then driven to be partially inserted again until the target transplanting depth is reached and the insertion is stopped. Then the first cylinder 531 is started to drive the horizontal connecting plate 532 to move vertically downward, and then the two groups of horizontal partitions 54 are simultaneously pushed vertically downward. In this process, the horizontal partition 54 is gradually switched from the first state to the second state, that is, the lowermost end of the horizontal partition 54 will extend into the load-bearing groove 5121, and the lowermost ends of the two groups of horizontal partitions 54 are gradually horizontally approached from both ends of the load-bearing groove 5121 until they fit. When the two groups of transverse partitions 54 are fitted together, the magnet bars 543 at the ends of the transverse partitions 54 will attract each other and be firmly adsorbed together, so that the two groups of transverse partitions 54 are pressed against each other to close the lower opening of the rectangular quantitative frame 51. At the same time, in this process, the two groups of transverse partitions 54 will separate part of the silt in the experimental farmland in the rectangular space, thereby forming a rectangular experimental soil area.

[0040] It is worth noting that setting the front end faces of the two groups of magnet strips 543 as relatively inclined extrusion slopes has another function, that is, when the two groups of magnet strips 543 are close to each other, the silt at the end of the magnet strip 543 can be squeezed out between the ends of the two magnet strips 543 by tilting upward or tilting downward, so that the two magnet strips 543 can fit better. Compared with the vertical setting, the inclined extrusion slope can make the silt between the two magnet strips 543 easier to be squeezed out. At the same time, the silt squeezed out by tilting upward or tilting downward is more uniform, so that the amount of silt in the rectangular test soil area can be It is closer to the amount in the current area of ​​the actual test farmland. At the same time, when there is silt remaining in the load-bearing groove 5121, the outlet groove 5122 connected to the load-bearing groove 5121 can push the silt remaining in the load-bearing groove 5121 from the load-bearing groove 5121 to the outlet groove 5122 through the extrusion force generated when the transverse partition 54 slides in the load-bearing groove 5121, so as to avoid the silt in the load-bearing groove 5121 blocking the fitting of the two transverse partitions 54; and due to the setting of the polytetrafluoroethylene film 541, the silt is not easy to adhere to the surface of the polytetrafluoroethylene film 541, thereby improving the fitting effect of the two transverse partitions 54.

[0041] After the silt in the rectangular test soil area is separated, the limiting mechanism 6 is immediately started to shape the surrounding of the rectangular quantitative frame 51 to avoid the rectangular mud pit from collapsing to a certain extent after the rectangular quantitative frame 51 is removed; at this time, the rotating motor 413 is started to reverse, thereby driving the rectangular quantitative frame 51 to move vertically upward until it moves to a position where the test personnel can insert the seedlings into the rectangular test soil area when standing, and then stops moving. At this time, the test personnel can insert the test seedlings one by one into the rectangular test soil area.

[0042] After the seedlings are inserted, the rotating motor 413 is started to rotate forward, driving the rectangular quantitative frame 51 back to the initial descending position, and then the first cylinder 531 is started to extend the piston rod of the first cylinder 531 vertically upward, switching the transverse partition 54 from the second state to the first state again. It is worth noting that this process needs to be carried out slowly to avoid affecting the shape of the rectangular test soil area and the insertion position of the seedlings due to too fast speed. When the transverse partition 54 slowly retreats into the vertical cavity 71, the rectangular test soil area returns to the mud pit again, thus completing the precision sowing of the test seedlings in the rectangular test soil area, effectively improving the depth accuracy of the test seedlings.

[0043] For example, refer to 2. Figure 3, scale lines are vertically arranged on both sides of the outer wall of the short plate body 512, and the scale lines can directly reflect the depth of the rectangular quantitative frame 51 being inserted. Furthermore, the scale number at the lowest end of the scale line is 0, and the position that is level with the scale number 0 is the upper inner wall surface of the horizontal cavity, and therefore corresponds to the upper surface of the horizontal partition 54 in a horizontal state. After such a setting, the test personnel can directly understand the depth to which the corresponding rectangular quantitative frame 51 has been inserted by observing the scale number corresponding to the scale line and the silt surface of the test farmland.

[0044] It is worth noting that the inner and outer surfaces of the rectangular quantitative frame 51 are covered with polytetrafluoroethylene, which can reduce the amount of sludge adhering to the surface of the rectangular quantitative frame 51 and reduce the labor intensity of subsequent cleaning. At the same time, it can also reduce the impact of the removal of the transverse partition 54 on the planting position of the seedlings in the rectangular test soil area during the process of the transverse partition 54 slowly switching from the second state to the first state, thereby improving the accuracy of the test.

[0045] In some embodiments, if the effect of the removal of the transverse partition 54 on the planting position of the seedlings in the rectangular test soil area is to be reduced, the test personnel do not need to directly plant the seedlings on the top wall of the transverse partition 54 in the second state (that is, the bottom wall of the rectangular test soil area) when planting the seedlings at the beginning, but can directly plant them in the upper area near the bottom of the rectangular test soil area, that is, leave a distance between the roots of the seedlings and the top wall of the transverse partition 54 in the second state. In this way, in the process of the transverse partition 54 slowly switching from the second state to the first state, the roots of the seedlings will be less affected by the retraction of the vertical cavity 71 of the transverse partition 54, because the roots of the seedlings do not touch the top wall of the transverse partition 54 in the second state, but are separated from the top wall of the transverse partition 54 in the second state by a large amount of silt. In this way, the roots of the seedlings can be prevented from being offset due to the removal of the transverse partition 54 to a certain extent.

[0046] In some embodiments, in combination Figure 3 , Fig. 9 The limiting mechanism 6 includes a bracket 61, a second cylinder 62, a rectangular limiting frame 63 and an insertion strip 64. The bracket 61 is horizontally arranged between the movable plate 32 and the guide block 34. The second cylinder 62 is vertically arranged on the bracket 61. The piston rod of the second cylinder 62 extends vertically downward and is connected to the top wall of the rectangular limiting frame 63. The rectangular limiting frame 63 is slidably sleeved on the outer periphery of the rectangular quantitative frame 51.

[0047] Exemplarily, four insertion strips 64 are provided on the lower bottom wall of the rectangular limit frame 63, and the four insertion strips 64 are vertically arranged in pairs. The insertion strip 64 has a tip 641 and a drainage surface 642. The tip 641 is provided at the bottom of the insertion strip 64, and the drainage surface 642 is provided on the side of the tip 641 away from the rectangular quantitative frame 51. The drainage surface 642 is used to guide excess silt to the side away from the rectangular space when the insertion strip 64 is inserted into the silt; and, when the insertion strip 64 moves down to a position opposite to the insertion strip, an extrusion space is formed between the insertion strip 64 and the insertion strip for filling in part of the silt outside the rectangular space.

[0048] The second cylinder 62 is started, and the second cylinder 62 drives the rectangular limit frame 63 and the insertion bar 64 to move downward, so that the insertion bar 64 can enter the sludge in advance for guidance. Since the insertion bar 64 has a tip 641, it is easier to insert. Similarly, the setting of the drainage surface 642 can guide the excess sludge to the side away from the rectangular space, so as to avoid the sludge in the rectangular space being too different from the preset value.

[0049] In some embodiments, in combination Figure 6 , Figure 7 , Fig.10 as well as Fig.11 The precision rice seeding and transplanting machine of the present application further includes a seedling separation component 8 , which can be placed in a rectangular test soil area formed in a rectangular quantitative frame 51 .

[0050] Exemplarily, the seedling separation assembly 8 includes a top plate 81, a separation hollow column 82, an air bag 83, and an arc-shaped elastic shielding sheet 84, wherein the plate surface area of ​​the top plate 81 is smaller than the inner frame cross-sectional area of ​​the rectangular quantitative frame 51, and the separation hollow column 82 is vertically arranged on the lower plate surface of the top plate 81 with a length less than the height of the rectangular test soil area formed in the rectangular quantitative frame 51. When the horizontal partition 54 is in the second state, the separation hollow columns 82 on both sides of the vertical center line where the two opposite magnet strips 543 are attached are symmetrically distributed, and a separation cavity 821 for inserting the seedlings is formed in the separation hollow column 82. A plurality of insertion ports 811 corresponding to the separation cavity 821 are opened through the top plate 81, and the air bag 83 is arranged on the inner bottom wall between the adjacent separation hollow columns 82 on the top plate 81. Exemplarily, the top plate 81 is configured as a light-transmitting glass plate, and a plurality of air holes are opened on the surface of the top plate 81.

[0051] Furthermore, one side column wall of the separating hollow column 82 is connected to the top plate 81 and is penetrated by a vertical groove 822 for the arc-shaped elastic shielding piece 84 to fit in and be inserted into. The length of the arc-shaped elastic shielding piece 84 is greater than the length of the vertical groove 822, and in the process of inserting the arc-shaped elastic shielding piece 84 into the vertical groove 822, the bent portion of the arc-shaped elastic shielding piece 84 undergoes a linear deformation under the restrictive action of the vertical groove 822, and returns to the initial bending shape after the bent portion of the arc-shaped elastic shielding piece 84 extends out of the lower end opening of the vertical groove 822, so as to partially block the lower end opening of the separating cavity 821. At this time, the arc-shaped elastic shielding pieces 84 on both sides of the center line where the two opposite magnet bars 543 are in contact are bent toward opposite sides respectively.

[0052] After such arrangement, after the transverse partition 54 in the second state forms a rectangular test soil area, the test personnel can place the top plate 81 into the rectangular quantitative frame 51, and insert the partition hollow column 82 into the rectangular test soil area while the top plate 81 is on the upper surface of the rectangular test soil area. At this time, due to the arrangement of the air bag 83, the top plate 81 can stably cover the upper surface of the rectangular test soil area and is not easy to sink. At this time, multiple partition cavities 821 can be used for multiple seedlings to be inserted one by one, and the formed partition cavities 821 can cultivate multiple seedlings in the same rectangular test soil area in separated areas. The advantage of the separated cultivation areas is that if it is necessary to test the cultivation effect of different seedlings in the same rectangular test soil area with external nutrients during the test, the nutrients required for the test can be directly added to different partition cavities 821 in the same rectangular test soil area to test the growth conditions of different seedlings in the same rectangular test soil area after being cultivated with different nutrients, which is beneficial to the seedling cultivation work in the research and development stage.

[0053] At the same time, since the removal of the transverse partition 54 has an impact on the planting position of the seedlings in the rectangular test soil area, after the arc-shaped elastic shielding piece 84 passes through the lower end of the vertical groove 822, the bent portion of the arc-shaped elastic shielding piece 84 can block the lower end opening of the partition cavity 821, so that in the process of switching the transverse partition 54 from the second state to the first state, the bent portion of the arc-shaped elastic shielding piece 84 can effectively reduce the impact of the transverse partition 54 on the silt in the partition cavity 821 after the movement, and finally make the position of the seedlings inserted in the partition cavity 821 less likely to be affected by the withdrawal of the transverse partition 54 and shifted, thereby improving the planting effect of the seedlings. It is worth mentioning that after the seedlings are planted in the entire rectangular test soil area and put back into the test farmland, the seedling partition assembly 8 does not need to be removed, but stays in the rectangular test soil area.

[0054] Finally, since the bent portions of the arc-shaped elastic shielding sheet 84 on both sides of the center line where the two opposite magnet strips 543 meet are bent toward opposite sides, during the process of the two transverse partitions 54 in the second state switching to the first state, the bent portions of the arc-shaped elastic shielding sheet 84 at the corresponding positions can form a gradually shrinking guide gap 9 with the corresponding straight portion of the transverse partition 54 in the second state that has exited. Under the action of this guide gap 9, even if the transverse partition 54 in the second state causes part of the sludge above it to shift during the process of switching to the first state, most of it will avoid the separation cavity 821 under the guidance and avoidance of the guide gap 9, thereby making the seedlings in the separation cavity 821 less susceptible to being affected after the transverse partition 54 switches from the second state to the first state. Exemplarily, the arc-shaped elastic shielding sheet 84 is configured as a copper sheet or a patch, which itself has a certain elastic deformation.

[0055] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
