Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tamarix seedling culture, and particularly relates to a tamarix seedling culture device. BACKGROUND

[0002] Tamarix is a tree plant of tamaricaceae tamarix, and tamarix is a salt and alkali tolerant plant. Tamarix can grow in soil with a salt content of 0.5% or more, and even in severe saline-alkali soil with a salt content of 1%. Therefore, tamarix can be used as the main vegetation for ecological restoration of beach areas.

[0003] Before tamarix is planted in a beach area, a large number of tamarix need to be cultivated, and cutting seedling culture can meet the large cultivation work. Before cutting, on the one hand, the cutting cuttings need to be treated, and on the other hand, trenches need to be dug on the land to place the nutrient pots in the trenches. After the cuttings are soaked and disinfected, the cuttings are inserted into the nutrient pots, one cutting is inserted into each nutrient pot, and the top of the cutting needs to protrude 2-3 centimeters from the soil. After cutting, the soil needs to be watered thoroughly, and then covered with plastic film to achieve the effect of heat preservation.

[0004] In the prior art, the operator needs to place the nutrient pots into the trenches one by one, and after the cultivation is completed, the operator also needs to take out the nutrient pots from the trenches one by one, which is low in efficiency. When the operator inserts the cuttings into the soil of the nutrient pots, when there are multiple nutrient pots in the trench transversely, the operator needs to insert the cuttings into the nutrient pots close to the middle of the trench, which is relatively laborious because the distance between the nutrient pots and the edge of the trench is far. SUMMARY

[0005] The embodiment of the application provides a tamarix seedling culture device, which aims to solve the technical problems that the nutrient pots are low in efficiency in the process of being taken out from the trenches, and it is relatively laborious to insert the cuttings into the nutrient pots close to the middle of the trench.

[0006] To achieve the above-mentioned purpose, the technical scheme adopted by the application is:

[0007] The application provides a tamarix seedling culture device, which comprises:

[0008] A U-shaped support plate is placed in the trench, and the outer side of the U-shaped support plate is in contact with the inner side of the trench. The top of the U-shaped support plate has an outwardly extending flange, the bottom of the flange is in contact with the land on the outer side of the top of the trench, and the top of the flange has a C-shaped slide. A plurality of nutrient pots are placed in the U-shaped support plate along the transverse and longitudinal directions.

[0009] A connecting plate is transversely arranged on the U-shaped support plate. The two ends of the connecting plate are respectively in sliding fit with the C-shaped slides on the two sides of the U-shaped support plate, and are fixed in the height direction. The connecting plate has a plurality of placement holes for the cuttings to pass through, and the placement holes correspond to the transverse nutrient pots one by one. The top of the connecting plate has a guide column.

[0010] The pressing plate has a through hole in sliding fit with the guide post; the bottom of the pressing plate has a protrusion corresponding to the placement hole, and the pressing plate can press down the cutting plug, and the protrusion can push the cutting plug out of the placement hole.

[0011] In a possible implementation, the guide post is at least two, and the guide post at one end of the pressing plate is provided with a limiting part, and the limiting part extends radially outward along the guide post; the limiting part is connected with a ring structure, and the guide post is provided with an annular groove for placing the ring structure;

[0012] The pressing plate is provided with a through hole for passing through the limiting part, and the limiting part is in the first state when it is aligned with the through hole of the pressing plate, and the limiting part is in the second state when it is in contact with the bottom of the pressing plate.

[0013] In a possible implementation, one side of the limiting part has an arc-shaped groove, and the arc-shaped groove is communicated with the bottom of the limiting part;

[0014] The guide post is connected with an insertion block in plug-in fit with the arc-shaped groove, and when the insertion block is in contact with the end of the arc-shaped groove, the limiting part is in plug-in fit, and the limiting part is in the first state.

[0015] In a possible implementation, the outer peripheral wall of the ring structure is on the same circumferential surface as the outer peripheral wall of the guide post, so as to facilitate the pressing plate to pass through the ring structure.

[0016] In a possible implementation, the bottom of the pressing plate has a stop block, and when the limiting part is rotated to the second state, the limiting part is in contact with the stop block.

[0017] In a possible implementation, the guide post is provided with a mounting groove at one end of the ring structure, and a torsion spring is connected in the mounting groove, and the two ends of the torsion spring are connected with the ring structure and the guide post respectively, and the torsion spring can rotate the limiting part from the first state to the second state.

[0018] The top of the limiting part has an insertion hole, and the guide post is provided with a positioning mechanism in fit with the insertion hole, so as to keep the limiting part in the first state.

[0019] In a possible implementation, the guide post is provided with a key groove at a position above the limiting part, and the positioning mechanism comprises:

[0020] A positioning ring is slidingly arranged on the guide post; the inner peripheral wall of the positioning ring has a protrusion in sliding fit with the key groove, so as to circumferentially limit the positioning ring;

[0021] A positioning rod is connected with the positioning ring at the top end, and the bottom end can be in plug-in fit with the insertion hole;

[0022] When the pressing plate slides to the positioning ring position from bottom to top, the pressing plate continues to slide upward to separate the positioning rod from the insertion hole, and the limiting component rotates to the second state under the torsional force of the torsional spring.

[0023] In a possible implementation, the bottom of the connecting plate is provided with a receiving cavity, and a roller is rotatably arranged in the receiving cavity. A part of the roller is located outside the connecting plate, and the roller is in rolling cooperation with the flange.

[0024] In a possible implementation, each flange is provided with two limiting plates, and the two limiting plates are in contact with two ends of the roller respectively to limit the position of the roller in the transverse direction.

[0025] The flange is provided with a positioning hole between the two limiting plates, and a plurality of positioning holes are arranged along the length direction of the flange. Each positioning hole is provided with a positioning block. When the positioning block is in contact with the roller, the sliding position of the limiting connecting plate is limited. When the roller rolls over the positioning block, the bottom of the positioning block can be inserted into the soil.

[0026] In a possible implementation, one side of the connecting plate is connected with a water tank, the water tank is provided with a water outlet pipe corresponding to each transversely arranged nutrient pot, the water tank is connected with a valve, and the valve is connected with a power water source through a hose.

[0027] Compared with the prior art, the U-shaped support plates are placed in the groove, and the nutrient pots are placed on the U-shaped support plates. When the cultivation is completed and the nutrient pots need to be transported, the U-shaped support plates are transported to take out the plurality of nutrient pots from the groove at the same time, thereby reducing the situation of transporting the nutrient pots one by one and improving the transportation efficiency. When the cutting cuttings in the nutrient pots are inserted, the connecting plate and the C-shaped slide are in sliding cooperation, the position of the connecting plate in the height direction is fixed, and then the operator puts the cuttings into the placing hole of the connecting plate. At this time, the bottom of the cutting is in contact with the top of the soil. The pressing plate presses the cutting downward, and the protruding part pushes the cutting out of the placing hole, and the cutting process is completed. The above cutting process not only inserts all the cuttings in the transverse direction into the soil in the corresponding nutrient pot, but also makes the top of the cutting protrude from the soil by a preset length, thereby meeting the requirement of cutting. Through the above arrangement, when there are a plurality of nutrient pots in the transverse direction of the groove, the cutting difficulty of the nutrient pots at the middle position of the groove can be reduced.

DETAILED DESCRIPTION

[0043] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0044] Please refer to Figures 1 to 14 , now a Tamarix seedling raising device provided by the present application will be described. The Tamarix seedling raising device comprises a U-shaped support plate 1, a connecting plate 2 and a pressing plate 3; the U-shaped support plate 1 is placed in a groove 4, and the outer side of the U-shaped support plate 1 is in contact with the inner side of the groove 4; the top of the U-shaped support plate 1 has a flange 11 extending outward, the bottom of the flange 11 is in contact with the land on the outer side of the top of the groove 4, and the top of the flange 11 has a C-shaped slide 12; a plurality of nutrient pots 5 are placed in the U-shaped support plate 1 along the transverse and longitudinal directions; the connecting plate 2 spans the U-shaped support plate 1; the two ends of the connecting plate 2 are respectively in sliding fit with the C-shaped slides 12 on the two sides of the U-shaped support plate 1 and are fixed in the height direction; the connecting plate 2 has a plurality of placing holes 21 for the cuttings to pass through, and the placing holes 21 correspond to the transverse nutrient pots 5 one by one; the top of the connecting plate 2 has a guide column 22; the pressing plate 3 has a through hole in sliding fit with the guide column 22; the bottom of the pressing plate 3 has a convex part 31 corresponding to the placing hole 21, the pressing plate 3 can press the cutting downward, the convex part 31 can push the cutting out of the placing hole 21, the convex part 31 is connected with a buffer layer, and the length of the convex part 31 is greater than the length of the placing hole 21, so that the convex part 31 can push the cutting out of the placing hole 21. After cutting is completed, the connecting plate 2 is separated from the U-shaped support plate 1.

[0045] Compared with the prior art, the device for cultivating desertification-resistant plants provided by the application can place multiple U-shaped support plates 1 in the groove 4 and place the nutrient pots 5 on the U-shaped support plates 1. When the nutrient pots 5 need to be carried out at the end of cultivation, the multiple nutrient pots 5 can be carried out from the groove 4 at the same time by carrying the U-shaped support plates 1, thereby reducing the situation of carrying out one by one and improving the carrying efficiency. When cutting the cutting seedlings in the nutrient pots 5, the position of the connecting plate 2 in the height direction can be fixed by the sliding cooperation of the connecting plate 2 and the C-shaped slide 12, and then the operator puts the cutting seedlings into the placing hole 21 of the connecting plate 2, at which time the bottom of the cutting seedling is in contact with the top of the soil. The cutting seedling is pressed downward by the pressing plate 3 and is pushed out of the placing hole 21 by the protruding part 31, and the cutting process is completed. The above cutting process not only can insert all the cutting seedlings in the transverse direction into the soil in the corresponding nutrient pot 5, but also can make the top of the cutting seedling protrude from the soil by a preset length, thereby meeting the requirement of cutting. Through the above arrangement, when multiple nutrient pots 5 exist in the transverse direction of the groove 4, the cutting difficulty of the nutrient pots 5 at the middle position of the groove 4 can be reduced.

[0046] It should be noted that when cutting in batches, several grooves 4 are opened on the land, and the adjacent grooves 4 are spaced one meter apart. Several U-shaped support plates 1 are placed in each groove 4, so as to facilitate the batch taking out of the nutrient pots 5 in the later stage. After the cutting seedlings are cut in the nutrient pots 5 in the groove 4, the groove 4 needs to be covered with plastic cloth to play a role in heat preservation and moisture retention. The C-shaped slides 12 on the two flanges 11 are oppositely arranged, the two ends of the connecting plate 2 are respectively located in the corresponding C-shaped slides 12, the C-shaped slides 12 on the multiple U-shaped support plates 1 are aligned with each other, so as to facilitate the smooth sliding of the connecting plate 2 from one U-shaped support plate 1 to another U-shaped support plate 1. The top of the C-shaped slide 12 has a connecting hole 13 for inserting the end of the arc-shaped support rod 14. After the cutting is completed, the two ends of the arc-shaped support rod 14 are respectively inserted into the corresponding connecting holes 13. The arc-shaped support rod 14 can play a role of framework, and then the plastic cloth is covered on the arc-shaped support rod 14. The edge position of the plastic cloth is lowered to the ground. The bricks or other heavy objects can be pressed on the plastic cloth to ensure the stability of the plastic cloth. The arc-shaped support rod 14 can provide a certain space for the growth of the cutting seedlings, thereby reducing the situation that the plastic cloth is directly covered on the cutting seedlings.

[0047] When the operator puts the cutting seedling into the placing hole 21 of the connecting plate 2 by the right hand, the left hand of the operator can be placed on the connecting plate 2, and the connecting plate 2 can support the left hand of the operator, thereby facilitating the right hand of the operator to put the cutting seedling into the placing hole. When the left hand of the operator puts the cutting seedling into the placing hole of the connecting plate 2, the right hand of the operator can be placed on the connecting plate 2, and the connecting plate 2 can support the right hand of the operator, thereby facilitating the left hand of the operator to put the cutting seedling into the placing hole 21.

[0048] To ensure the stability of the nutrient pot 5 on the U-shaped support plate 1, a barrier 15 is fixedly installed on the U-shaped support plate 1 to limit the nutrient pot 5 and reduce the possibility of the nutrient pot 5 falling off the U-shaped support plate 1 when lifting it upwards or when moving it.

[0049] In some embodiments, such as Figures 1 to 14 As shown, there are at least two guide posts 22. The guide post 22 located at one end of the pressure plate 3 is rotatably provided with a limiting component 6. The limiting component 6 extends radially outward along the guide post 22. An annular structure 61 is connected to the limiting component 6. The guide post 22 has an annular groove for placing the annular structure 61. The pressure plate 3 has a through hole for the limiting component 6 to pass through. When the limiting component 6 is aligned with the through hole of the pressure plate 3, it is in the first state. When the limiting component 6 is in contact with the bottom of the pressure plate 3, it is in the second state.

[0050] Taking two guide posts 22 as an example, the two guide posts 22 are located near the two ends of the connecting plate 2 respectively; the inner diameter of the through hole on the pressure plate 3 that slides with the guide post 22 is the same as the outer diameter of the guide post 22, so it can play a radial limiting role on the pressure plate 3 and reduce the situation of the pressure plate 3 swinging left and right; the through hole on the pressure plate 3 for the limiting component 6 to pass through is a strip hole 32. The width of the limiting component 6 is smaller than the diameter of the guide post 22, so the width of the strip hole 32 is also smaller than the diameter of the guide post 22.

[0051] Taking four nutrient pots 5 as an example, by setting a limiting component 6 on the guide post 22, during the process of inserting the cuttings into the placement hole 21 on the connecting plate 2, the limiting component 6 provides support for the pressing plate 3, which can keep the pressing plate 3 at a high position, thus making it easier for the operator to insert the cuttings into the placement hole 21; after the cuttings are inserted, the cuttings pass through the connecting plate 2, the bottom of the cuttings contacts the top of the soil in the nutrient pot 5, and the top of the cuttings is above the connecting plate 2; when the limiting component 6 is rotated to the first state, the pressing plate 3 can pass through the limiting component 6, and the operator can press down the pressing plate 3 to insert the four horizontally arranged cuttings into the corresponding nutrient pots 5 respectively, and the length of the four cuttings left outside the soil is the same, which meets the requirements of cutting.

[0052] The annular structure 61 rotates with the annular groove, and the outer peripheral wall of the annular structure 61 and the outer peripheral wall of the guide post 22 are on the same circumferential surface, which facilitates the pressure plate 3 to pass through the annular structure 61; the two ends of the annular structure 61 contact the two ends of the annular groove respectively, so as to limit the annular structure 61 in the height direction and prevent the annular structure 61 from being displaced in the height direction.

[0053] When the limiting component 6 is in the first state, the limiting component 6 is aligned with the through hole on the pressing plate 3, and the pressing plate 3 can pass through the limiting component 6; when the limiting component 6 is in the second state, the pressing plate 3 is above the limiting component 6, the bottom of the pressing plate 3 is in contact with the top of the limiting component 6, and the limiting component 6 supports the pressing plate 3 to avoid the pressing plate 3 from falling down.

[0054] In some embodiments, as shown in Figures 1 to 14 One side of the limiting component 6 has an arc-shaped slot 62, which is connected to the bottom of the limiting component 6; the guide column 22 is connected with an insertion block 221 which is inserted into the arc-shaped slot 62; when the insertion block 221 is in contact with the end of the arc-shaped slot 62, the limiting component 6 is inserted into place, and the limiting component 6 is in the first state.

[0055] It should be noted that the insertion block 221 is fixed on the guide column 22, and the insertion block 221 is aligned with the through hole on the pressing plate 3; when the pressing plate 3 passes through the limiting component 6, the insertion block 221 avoids interfering with the pressing plate 3; through the insertion of the insertion block 221 and the limiting component 6, when the arc-shaped slot 62 is in contact with the insertion block 221, the limiting component 6 is directly below the through hole of the pressing plate 3, so the insertion block 221 can position the limiting component 6, reducing the situation that the limiting component 6 deviates and the pressing plate 3 cannot pass through the limiting component 6.

[0056] In order to limit the second state of the limiting component 6, a stop block 33 is fixed on the bottom of the pressing plate 3; when the limiting component 6 is in contact with the stop block 33, the stop block 33 limits the limiting component 6, and the top of the limiting component 6 is in contact with the bottom of the pressing plate 3, and the limiting component 6 supports the pressing plate 3; when the limiting component 6 is rotated too much, the position of the limiting component 6 can be manually adjusted to rotate to the position in contact with the stop block 33; the length of the protruding part 31 is greater than the sum of the length of the stop block 33 and the length of the placement hole 21, so that the protruding part 31 can push the insertion block out of the placement hole 21.

[0057] In some embodiments, as shown in Figures 1 to 14 The guide column 22 is provided with a mounting slot 222 at one end of the ring-shaped structure 61, and the depth of the mounting slot 222 is smaller than the depth of the ring-shaped slot, so that the mounting slot 222 does not affect the limiting of the ring-shaped structure 61 by the ring-shaped slot, avoiding displacement of the ring-shaped structure 61 in the height direction; a torsion spring (not shown in the figure) is connected in the mounting slot 222, and the two ends of the torsion spring are connected with the ring-shaped structure 61 and the guide column 22 respectively, and the torsion spring can rotate the limiting component 6 from the first state to the second state; the top of the limiting component 6 has an insertion hole 63, and the guide column 22 has a positioning mechanism 7 which cooperates with the insertion hole 63 to keep the limiting component 6 in the first state.

[0058] It should be noted that by providing the mounting groove 222 on the guide column 22, the torsion spring can be mounted in the mounting groove 222, and the torsion spring does not protrude outside the guide column 22, so that the influence of the torsion spring on the sliding of the pressing plate 3 can be avoided; since the groove depth of the mounting groove 222 is smaller than the groove depth of the annular groove, the top of the annular groove is not completely communicated with the mounting groove 222, so that the top of the annular groove does not lose the function of limiting the height of the ring structure 61.

[0059] Since the torsion spring in the mounting groove 222 provides a torsion force to the ring structure 61, when the torsion force of the torsion spring is the smallest, the limiting component 6 is in the second state, i.e., the state of supporting the pressing plate 3, at this time the pressing plate 3 cannot pass through the limiting component 6 downward; by providing the positioning mechanism 7 on the guide column, and by cooperating the positioning mechanism 7 with the insertion hole 63 of the limiting component 6, the limiting component 6 can be kept in the first state, although the torsion force provided by the torsion spring to the limiting component 6 has a tendency to rotate the limiting component 6 to the second state, but the positioning mechanism 7 can position the limiting component 6, so that the limiting component 6 is stably kept in the first state, so as to facilitate the pressing plate 3 to pass through the limiting component 6.

[0060] In some embodiments, as shown in Figures 1 to 14 The guide column 22 at a position above the limiting component 6 has a key groove 223, and the positioning mechanism 7 includes a positioning ring 71 and a positioning rod 72; the positioning ring 71 is slidingly arranged on the guide column 22; the inner circumferential wall of the positioning ring 71 has a protrusion 73 which slidingly cooperates with the key groove 223 to circumferentially limit the positioning ring 71; the top end of the positioning rod 72 is connected with the positioning ring 71, and the bottom end can be insertedly cooperated with the insertion hole 63; wherein when the pressing plate 3 is slid upward to the position of the positioning ring 71, the pressing plate 3 continues to slide upward to separate the positioning rod 72 from the insertion hole 63, and the limiting component 6 rotates to the second state under the torsion force of the torsion spring.

[0061] It should be noted that the positioning ring 71 is circumferentially limited by the protrusion 73 and the key groove 223, so that the positioning ring 71 can only slide in the up-down direction; when the limiting component 6 rotates to the first state, the positioning rod 72 can be insertedly cooperated with the insertion hole 63 on the limiting component 6 to limit the limiting component 6 in the first state.

[0062] The top of the guide column 22 is a split structure, for the convenience of description, the guide column 22 is divided into an upper structure and a lower structure, the key groove 223 is located on the outer side wall of the upper structure; the top of the lower structure has an insertion column 224, the annular structure 61 on the limiting component 6 is sleeved on the insertion column 224, the top of the annular structure 61 is coplanar with the top of the insertion column 224; the bottom of the upper structure has a convex column 225, the diameter of the convex column 225 is larger than the diameter of the insertion column 224, after the convex column 225 contacts with the insertion column 224, an annular groove is formed between the convex column 225 and the lower structure, and a mounting groove 222 is formed between the convex column 225 and the upper structure; a part of the bottom end of the convex column 225 contacts with the annular structure 61, so that the annular structure 61 can be limited.

[0063] The insertion column 224 has a square hole 226, the convex column 225 has a square column 227, the convex column 225 is inserted and matched with the square column 227 and the square hole 226; the top of the insertion column 224 has a threaded hole, the upper structure has a through hole aligned with the threaded hole, the through hole also penetrates the convex column 225, after the square column 227 is inserted and matched with the square hole 226, the upper structure is connected to the lower structure through a bolt.

[0064] The top of the upper structure is provided with a mounting cap 23, the inner circumferential wall of the mounting cap 23 has an internal thread; the outer circumferential wall of the upper structure close to the top has an external thread, the mounting cap 23 is threadedly matched with the upper structure; the mounting cap 23 and the positioning ring 71 have a space for the positioning ring 71 to slide.

[0065] The mounting cap 23 and the positioning ring 71 are provided with a spring 24, the two ends of the spring 24 are connected with the mounting cap 23 and the positioning ring 71 respectively, the spring 24 can provide an elastic force to the positioning ring 71, when the pressing plate 3 pushes the positioning ring 71 upward, the positioning ring 71 compresses the spring 24, when the pressing plate 3 removes the pushing force, the positioning ring 71 moves downward under the action of its own gravity and the elastic force of the spring 24, and finally abuts against the top of the pressing plate 3.

[0066] The side of the positioning rod 72 towards the limiting component 6 has an inclined surface, when the limiting component 6 rotates from the second state to the first state, the limiting component 6 can push the positioning rod 72 upward by contacting with the inclined surface, and the bottom of the positioning rod 72 is located at the top of the limiting component 6; when the limiting component 6 is inserted and matched with the insertion block 221, the positioning rod 72 is aligned with the insertion hole 63, the positioning rod 72 is inserted and matched with the insertion hole 63 under the action of the elastic force of the spring 24, at this time, the rotation of the limiting component 6 can be limited, so that the limiting component 6 is stable in the first state.

[0067] For example, the length of the positioning rod 72 inserted into the insertion hole 63 is less than the length of the stop block 33, and the distance of the positioning ring 71 sliding upward is less than the length of the stop block 33; when the positioning ring 71 slides to the maximum position, the positioning rod 72 is separated from the insertion hole 63, the limiting component 6 rotates under the action of the torsion spring, and finally abuts against the stop block 33; through the above setting, the situation that the limiting component 6 rotates too much can be reduced.

[0068] In some embodiments, as shown in Figures 1 to 14 The bottom of the connecting plate 2 is provided with a receiving cavity 25, and a roller 26 is rotatably arranged in the receiving cavity 25. A part of the roller 26 is located outside the connecting plate 2, and the roller 26 is in rolling cooperation with the flange 11.

[0069] Taking four rollers 26 as an example, two rollers 26 are arranged at the two ends of the bottom of the connecting plate 2. The specific connection manner of the roller 26 and the connecting plate 2 is that: a through hole is arranged at the center position of the roller 26, the side of the connecting plate 2 is provided with a through hole aligned with the receiving cavity 25, and the position of the receiving cavity 25 corresponding to the side of the connecting plate 2 is provided with a threaded hole; after the roller 26 is placed in the receiving cavity 25, a bolt with a light rod and a thread is inserted into the connecting plate 2, so that the light rod of the bolt is inserted and cooperated with the through hole of the roller 26, and the thread of the bolt is threadedly cooperated with the threaded hole of the receiving cavity 25; through the above setting, after the bolt is tightened on the connecting plate 2, the position of the roller 26 can be limited, and the roller 26 can rotate around its axis.

[0070] After the connecting plate 2 is placed on the C-shaped slide 12 on the flange 11, the roller 26 is in contact with the top of the flange 11, and the roller 26 is in rolling cooperation with the top of the flange 11, so that the sliding of the connecting plate 2 on the flange 11 is facilitated, the connecting plate 2 can be slid to the position of the corresponding row of nutrient pots 5, and then the cutting is inserted into the soil of the corresponding row of nutrient pots 5.

[0071] In some embodiments, as shown in Figures 1 to 14 Each flange 11 is provided with two limiting plates 16, and the two limiting plates 16 are in contact with the two ends of the roller 26 to limit the position of the roller 26 in the transverse direction; the position of the flange 11 between the two limiting plates 16 is provided with a positioning hole 17, and a plurality of positioning holes 17 are arranged along the length direction of the flange 11, and a positioning block 18 is arranged in each positioning hole 17; when the positioning block 18 is in contact with the roller 26, the sliding position of the connecting plate 2 is limited; when the roller 26 rolls over the positioning block 18, the bottom of the positioning block 18 can be inserted into the soil.

[0072] It should be noted that the two limiting plates 16 on the flange 11 can limit the roller 26, so that the roller 26 slides along the direction of the limiting plate 16; by setting the positioning block 18 on the movement path of the roller 26, and the top of the positioning block 18 is provided with a slope, when the roller 26 contacts the positioning block 18, the roller 26 can limit the effect, which is convenient for the operator to know the sliding position; after the cutting of the cutting stick is completed, the roller 26 rolls over the positioning block 18, which can make the bottom of the positioning block 18 inserted into the soil, and the top of the positioning block 18 slides into the positioning hole 17, so as to make way for the roller 26.

[0073] Since the C-shaped slide 12 limits the height of the connecting plate 2, when the roller 26 rolls over the positioning block 18, the positioning block 18 can slide downward; the bottom of the positioning block 18 has a sharp part 181, which facilitates the insertion of the bottom of the positioning block 18 into the soil when the roller 26 rolls over the positioning block 18.

[0074] In some embodiments, as shown in Figures 1 to 14 The water tank 8 is connected to one side of the connecting plate 2, and the water tank 8 has a water outlet pipe 81 corresponding to each of the transversely arranged nutrient pots 5, and the water tank 8 is connected with a valve 82, and the valve 82 is connected with a power water source through a hose, and the power water source refers to water under pressure, and after the valve 82 is opened, water can pass through the valve 82 and the water outlet pipe 81. The water outlet pipe 81 is arranged in a staggered manner with the cutting stick, and the bottom of the water outlet pipe 81 is higher than the top of the cutting stick inserted into the soil, so that the water outlet pipe 81 does not contact the cutting stick during movement.

[0075] It should be noted that the valve 82 is connected with a power water source through a hose, and after the valve 82 is opened, water can pass through the valve 82 into the water tank 8, and from the water outlet pipe 81 into the corresponding nutrient pot 5, to complete watering of the nutrient pot 5; the water tank 8 is arranged on the rear side of the connecting plate 2, and when the connecting plate 2 slides to the position of the next row of nutrient pots 5, the water outlet pipe 81 corresponds to the last row of nutrient pots 5, so that the water outlet pipe 81 can water the completed cutting stick nutrient pot 5.

[0076] The above only describes the preferred embodiments of the present application, and does not limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
