[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0020] Please also refer to Figures 1 to 14, now the Tamarix seedling raising device provided by the present application is 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 the groove 4, and the outer side of the U-shaped support plate 1 contacts 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 contacts the ground outside the top of the groove 4, and the top of the flange 11 has a C-shaped slide 12; a number of nutrient pots 5 are placed in the U-shaped support plate 1 in the horizontal and vertical directions; the connecting plate 2 spans the U-shaped support plate 1; the two ends of the connecting plate 2 are respectively slidably matched with the C-shaped slides 12 on both sides of the U-shaped support plate 1, and in terms of height, the U-shaped support plate 1 has a plurality of nutrient pots 5 ... U-shaped support plate 1 has a plurality of nutrient pots 5; the U-shaped support plate 1 has a plurality of nutrient pots 5; the U-shaped support plate 1 The connecting plate 2 is relatively fixed; the connecting plate 2 has a plurality of placement holes 21 for the cuttings to pass through, and the placement holes 21 correspond one to one with the horizontal nutrient pots 5; the top of the connecting plate 2 has a guide column 22; the pressing plate 3 has a through hole that slides with the guide column 22; the bottom of the pressing plate 3 has a protrusion 31 corresponding to the placement hole 21, the pressing plate 3 can press the cuttings downward, and the protrusion 31 can push the cuttings out of the placement hole 21. A buffer layer is connected to the protrusion 31, and the length of the protrusion 31 is greater than the length of the placement hole 21, so the protrusion 31 can push the cuttings out of the placement hole 21. After the cutting is completed, the connecting plate 2 is separated from the U-shaped support plate 1.

[0021] The U-shaped support plates 1 are placed in the groove 4, and the nutrient pots 5 are placed on the U-shaped support plates 1. When the nutrient pots 5 need to be transported after the cultivation is completed, the multiple nutrient pots 5 can be taken out of the groove 4 at the same time by transporting the U-shaped support plates 1, which reduces the need to transport them one by one and improves the transport efficiency. When the cuttings are inserted into the nutrient pots 5, the position of the connecting plate 2 can be fixed in the height direction by sliding with the C-shaped slide 12. Then the operator The cuttings are placed into the placement holes 21 of the connecting plate 2, at which time the bottoms of the cuttings are in contact with the top of the soil; the cuttings are pressed downward by the pressing plate 3, and the cuttings are pushed out of the placement holes 21 by the protrusions 31 to complete the cutting process; the above-mentioned cutting process can not only insert all the cuttings horizontally into the soil of the corresponding nutrient pots 5, but also make the tops of the cuttings extend out of the soil by a preset length, meeting the requirements of cutting; through the above-mentioned setting, when there are multiple nutrient pots 5 horizontally in the groove 4, the difficulty of cutting the nutrient pots 5 in the middle position of the groove 4 can be reduced.

[0022] It should be noted that when cuttings are planted in batches, several grooves 4 are opened on the land, with an interval of one meter between adjacent grooves 4, and several U-shaped support plates 1 are placed in each groove 4 to facilitate the batch removal of the nutrient pots 5 in the later stage; after the cuttings are planted in the nutrient pots 5 in the grooves 4, the grooves 4 need to be covered with plastic cloth to keep them warm and moisturize; the C-shaped slides 12 on the two flanges 11 are arranged oppositely, and the two ends of the connecting plate 2 are respectively located in the corresponding C-shaped slides 12, and the C-shaped slides 12 on the several U-shaped support plates 1 They are aligned with each other so that the connecting plate 2 can slide smoothly from one U-shaped support plate 1 to another U-shaped support plate 1; the top of the C-shaped slide 12 has a connection 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 connection holes 13. The arc-shaped support rod 14 can play the role of a skeleton, and then the arc-shaped support rod 14 is covered with plastic sheeting. The edge of the plastic sheeting droops to the ground, and heavy objects such as bricks can be used to press on the plastic sheeting to ensure the stability of the plastic sheeting. The arc-shaped support rod 14 can provide a certain space for the growth of the cuttings, reducing the situation where the plastic sheeting directly covers the cuttings.

[0023] When the operator places the cutting into the placement hole 21 of the connecting plate 2 with his right hand, the operator's left hand can be placed on the connecting plate 2, and the connecting plate 2 can support the operator's left hand, thereby facilitating the operator's right hand to place the cutting into the placement hole. When the operator's left hand places the cutting into the placement hole of the connecting plate 2, the operator's right hand can be placed on the connecting plate 2, and the connecting plate 2 can support the operator's right hand, thereby facilitating the operator's left hand to place the cutting into the placement hole 21.

[0024] In order to ensure the stability of the nutrient pot 5 on the U-shaped support plate 1, a fence 15 is fixedly provided on the U-shaped support plate 1 to limit the nutrient pot 5 and reduce the possibility of the nutrient pot 5 falling from the U-shaped support plate 1 when the U-shaped support plate 1 is lifted upward or when the U-shaped support plate 1 is carried.

[0025] In some embodiments, as Figures 1 to 14 As shown, there are at least two guide pillars 22, and the guide pillar 22 located at one end of the pressure plate 3 is rotatably provided with a limiting component 6, which extends radially outward along the guide pillar 22; an annular structure 61 is connected to the limiting component 6, and the guide pillar 22 has an annular groove for placing the annular structure 61; the pressure plate 3 has a through hole for passing the limiting component 6, and the limiting component 6 is in a first state when it is aligned with the through hole of the pressure plate 3, and is in a second state when the limiting component 6 contacts the bottom of the pressure plate 3.

[0026] Taking the two guide pillars 22 as an example, the two guide pillars 22 are respectively located near the two ends of the connecting plate 2; the inner diameter of the through hole on the pressure plate 3 that slides with the guide pillar 22 is the same as the outer diameter of the guide pillar 22, so it can play a role in radial limiting the pressure plate 3, reducing the situation where the pressure plate 3 swings left and right; the through hole on the pressure plate 3 for the limiting component 6 to pass through is a strip hole 32, and the width of the limiting component 6 is smaller than the diameter of the guide pillar 22, so the width of the strip hole 32 is also smaller than the diameter of the guide pillar 22.

[0027] Taking four nutrient pots 5 as an example, by arranging a limiting component 6 on the guide column 22, during the process of inserting the cuttings into the placement hole 21 on the connecting plate 2, the limiting component 6 provides support to the pressing plate 3, which can keep the pressing plate 3 at a high position, thereby facilitating the operator to insert the cuttings into the placement hole 21; after the cuttings are inserted, the cuttings pass through the connecting plate 2, and the bottom of the cuttings contacts the top of the soil in the nutrient pot 5, and the top of the cuttings is located 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 insert the four horizontally arranged cuttings into the corresponding nutrient pots 5 by pressing the pressing plate 3 downward, and the four cuttings are left at the same length outside the soil, which meets the requirements of cutting.

[0028] The annular structure 61 is rotatably matched with the annular groove, and the outer circumferential wall of the annular structure 61 and the outer circumferential wall of the guide column 22 are on the same circumferential surface, so that the pressure plate 3 can pass through the annular structure 61; the two ends of the annular structure 61 are respectively in contact with the two ends of the annular groove to limit the annular structure 61 in the height direction to avoid the annular structure 61 from being displaced in the height direction.

[0029] When the limiting component 6 is in the first state, the limiting component 6 is aligned with the through hole on the pressure plate 3, and the pressure plate 3 can pass through the limiting component 6; when the limiting component 6 is in the second state, the pressure plate 3 is located above the limiting component 6, and the bottom of the pressure plate 3 contacts the top of the limiting component 6. The limiting component 6 supports the pressure plate 3 to prevent the pressure plate 3 from falling downward.

[0030] In some embodiments, as Figures 1 to 14 As shown, one side of the limiting component 6 has an arc-shaped groove 62, which is connected to the bottom of the limiting component 6; the guide column 22 is connected to an insert block 221 that is plugged into the arc-shaped groove 62. When the insert block 221 contacts the end of the arc-shaped groove 62, the limiting component 6 is plugged into place and the limiting component 6 is in the first state.

[0031] It should be noted that the insert block 221 is fixed on the guide column 22, and the insert block 221 is aligned with the through hole on the pressure plate 3, so that when the pressure plate 3 passes through the limiting component 6, the insert block 221 is prevented from interfering with the pressure plate 3; the insert block 221 is plugged into and matched with the limiting component 6, and when the limiting component 6 is rotated until the end of the arc groove 62 contacts the insert block 221, the limiting component 6 is located directly below the through hole of the pressure plate 3, so the insert block 221 can play a positioning role for the limiting component 6, thereby reducing the situation where the pressure plate 3 cannot pass through the limiting component 6 due to deviation of the limiting component 6.

[0032] In order to limit the second state of the limiting component 6, a stop block 33 is fixedly provided at the bottom of the pressure plate 3. When the limiting component 6 contacts the stop block 33, the stop block 33 limits the limiting component 6. At this time, the top of the limiting component 6 contacts the bottom of the pressure plate 3, and the limiting component 6 supports the pressure plate 3. When the limiting component 6 rotates too much, the position of the limiting component 6 can be manually adjusted to rotate the limiting component 6 to a position that abuts the stop block 33. The length of the protrusion 31 is greater than the sum of the lengths of the stop block 33 and the placement hole 21, so that the protrusion 31 can push the cutting out of the placement hole 21.

[0033] In some embodiments, as Figures 1 to 14 As shown, the guide post 22 is provided with a mounting groove 222 at one end of the annular structure 61. The groove depth of the mounting groove 222 is less than the groove depth of the annular groove. Therefore, after the mounting groove 222 is opened, it will not affect the limiting effect of the annular groove on the annular structure 61, thereby avoiding displacement of the annular structure 61 in the height direction; a torsion spring (not shown in the figure) is connected to the mounting groove 222, and the two ends of the torsion spring are respectively connected to the annular structure 61 and the guide post 22, and the torsion spring can rotate the limiting component 6 from the first state to the second state; the limiting component 6 has a socket 63 at the top, and the guide post 22 has a positioning mechanism 7 that cooperates with the socket 63 to keep the limiting component 6 in the first state.

[0034] It should be noted that by providing a mounting groove 222 on the guide column 22, the torsion spring can be installed in the mounting groove 222, and the torsion spring will not protrude from the outside of the guide column 22, thereby avoiding the torsion spring from affecting the sliding of the pressure plate 3; 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 connected with the mounting groove 222, so the top of the annular groove will not lose the function of limiting the height of the annular structure 61.

[0035] Since the torsion spring in the mounting groove 222 provides a torsional force to the annular structure 61, when the torsion spring is subjected to the minimum force, the limiting component 6 is in the second state, that is, the state in which the limiting component 6 supports the pressure plate 3, and at this time the pressure plate 3 cannot pass downward through the limiting component 6; by arranging a positioning mechanism 7 on the guide column, the positioning mechanism 7 cooperates with the socket 63 of the limiting component 6, so that the limiting component 6 can be maintained in the first state. Although the torsion spring provides a torsion force to the limiting component 6 at this time, which tends to rotate the limiting component 6 to the second state, the positioning mechanism 7 can play a role in positioning the limiting component 6, so that the limiting component 6 can be stably maintained in the first state, so that the pressure plate 3 can pass through the limiting component 6.

[0036] In some embodiments, as Figures 1 to 14 As shown, the guide column 22 is located above the limiting component 6 and 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 slidably set on the guide column 22; the inner wall of the positioning ring 71 has a protrusion 73 that slides with the key groove 223 to circumferentially limit the positioning ring 71; the top end of the positioning rod 72 is connected to the positioning ring 71, and the bottom end can be plugged into the socket 63; wherein, when the pressure plate 3 slides from bottom to top to the position of the positioning ring 71, the pressure plate 3 continues to slide upward to separate the positioning rod 72 from the socket 63, and the limiting component 6 rotates to the second state under the torsion of the torsion spring.

[0037] It should be noted that the positioning ring 71 can circumferentially limit the positioning ring 71 by slidingly engaging with the key slot 223 through the protrusion 73, so that the positioning ring 71 can only slide in the up and down directions; when the limiting component 6 rotates to the first state, it is convenient for the positioning rod 72 to be plugged into and engaged with the socket 63 on the limiting component 6 to limit the limiting component 6 to the first state.

[0038] 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 keyway 223 is located on the outer wall of the upper structure; the top position of the lower structure is provided with a plug column 224, and the annular structure 61 on the limiting component 6 is sleeved on the plug column 224, and the top of the annular structure 61 is coplanar with the top of the plug column 224; the bottom of the upper structure is provided with a boss 225, and the diameter of the boss 225 is larger than the diameter of the plug column 224. After the boss 225 contacts the plug column 224, an annular groove is formed between the boss 225 and the lower structure, and an installation groove 222 is formed between the boss 225 and the upper structure; a part of the bottom end of the boss 225 contacts the annular structure 61, so it can limit the annular structure 61.

[0039] There is a square hole 226 on the plug column 224, and a square column 227 on the boss 225. The boss 225 is plugged into the square hole 226 through the square column 227; the top of the plug column 224 has a threaded hole, and the upper structure has a through hole aligned with the threaded hole, and the through hole also passes through the boss 225. After the square column 227 is plugged into the square hole 226, the upper structure is connected to the lower structure by bolts.

[0040] A mounting cap 23 is provided at the top of the upper structure, and the inner peripheral wall of the mounting cap 23 has an internal thread; the outer peripheral wall of the upper structure near the top has an external thread, and the mounting cap 23 is threadedly matched with the upper structure; there is space between the mounting cap 23 and the positioning ring 71 for the positioning ring 71 to slide.

[0041] A spring 24 is provided between the mounting cap 23 and the positioning ring 71. The two ends of the spring 24 are respectively connected to the mounting cap 23 and the positioning ring 71. The spring 24 can provide elastic force to the positioning ring 71. When the pressure plate 3 pushes the positioning ring 71 upward, the positioning ring 71 compresses the spring 24. When the pressure 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 pressure plate 3.

[0042] The positioning rod 72 has an inclined surface on the side facing the limiting component 6. 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 the inclined surface, and make the bottom of the positioning rod 72 located at the top of the limiting component 6; when the limiting component 6 and the plug block 221 are plugged into place, the positioning rod 72 is aligned with the socket 63, and the positioning rod 72 is plugged into and matched with the socket 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 stabilized in the first state.

[0043] Illustratively, the length of the positioning rod 72 inserted into the socket 63 is less than the length of the block 33, and the distance that the positioning ring 71 slides upward is less than the length of the block 33; when the positioning ring 71 slides upward to the maximum position, the positioning rod 72 is separated from the socket 63, and the limiting component 6 rotates under the action of the torsion spring and finally abuts against the block 33; through the above arrangement, the situation where the limiting component 6 rotates too much can be reduced.

[0044] In some embodiments, as Figures 1 to 14 As shown, the bottom of the connecting plate 2 has an accommodating cavity 25 , and a roller 26 is rotatably provided in the accommodating cavity 25 . A portion of the roller 26 is located outside the connecting plate 2 , and the roller 26 is in rolling engagement with the flange 11 .

[0045] Taking four rollers 26 as an example, two rollers 26 are respectively provided at both ends of the bottom of the connecting plate 2. The specific connection method between the rollers 26 and the connecting plate 2 is: a through hole is provided at the center position of the roller 26, and the side of the connecting plate 2 has a through hole aligned with the accommodating cavity 25, and the position on the accommodating cavity 25 corresponding to the side of the connecting plate 2 has a threaded hole; after the roller 26 is placed in the accommodating cavity 25, a bolt with a smooth rod and a thread is inserted into the connecting plate 2, so that the smooth rod of the bolt is plug-fitted with the through hole of the roller 26, and the thread of the bolt is threadedly fitted with the threaded hole of the accommodating cavity 25; through the above arrangement, 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.

[0046] After the connecting plate 2 is placed on the C-shaped slide 12 on the flange 11, the roller 26 contacts the top of the flange 11, and the roller 26 rolls with the top of the flange 11, thereby facilitating the sliding of the connecting plate 2 on the flange 11, and the connecting plate 2 can be slid to the position of the nutrient pot 5 of the corresponding row, thereby facilitating the insertion of the cuttings into the soil of the nutrient pot 5 of the corresponding row.

[0047] In some embodiments, as Figures 1 to 14 As shown, each flange 11 has two limit plates 16, which are in contact with the two ends of the roller 26 respectively to limit the position of the roller 26 laterally; the flange 11 has a positioning hole 17 between the two limit plates 16, and a number of positioning holes 17 are provided along the length direction of the flange 11, and each positioning hole 17 is provided with a positioning block 18; 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.

[0048] It should be noted that the two limit plates 16 on the flange 11 can limit the roller 26, so that the roller 26 slides along the direction of the limit plate 16; by arranging a positioning block 18 on the movement path of the roller 26, and the top of the positioning block 18 is provided with an inclined surface, when the roller 26 contacts the positioning block 18, the roller 26 can play a limiting role, which is convenient for the operator to know the sliding position; after the cuttings are inserted, the roller 26 runs over the positioning block 18, so that the bottom of the positioning block 18 can be inserted into the soil, and the top of the positioning block 18 slides into the positioning hole 17, thereby making way for the roller 26.

[0049] Since the C-shaped slide 12 serves as a height limiter for the connecting plate 2, the positioning block 18 can slide downward when the roller 26 rolls over the positioning block 18; the bottom of the positioning block 18 has a spike portion 181, which facilitates the bottom of the positioning block 18 to be inserted into the soil when the roller 26 rolls over the positioning block 18.

[0050] In some embodiments, as Figures 1 to 14 As shown, a water tank 8 is connected to one side of the connecting plate 2. The water tank 8 has a water outlet pipe 81 corresponding to the horizontally arranged nutrient pot 5. The water tank 8 is connected to a valve 82. The valve 82 is connected to a power water source through a hose. The power water source refers to pressurized water. After opening the valve 82, water can pass through the valve 82 and the water outlet pipe 81. The water outlet pipe 81 is staggered with the cuttings, and the bottom of the water outlet pipe 81 is higher than the top of the cuttings inserted into the soil. Therefore, during the movement of the water outlet pipe 81, the water outlet pipe 81 will not touch the cuttings.

[0051] It should be noted that the valve 82 is connected to a pressurized power water source through a hose. After the valve 82 is opened, water can pass through the valve 82 into the water tank 8 and enter the corresponding nutrient pots 5 from the outlet pipe 81, completing the watering of the nutrient pots 5; the water tank 8 is arranged on the rear side of the connecting plate 2. When the connecting plate 2 slides to the position of the next row of nutrient pots 5, the outlet pipe 81 corresponds to the nutrient pots 5 in the previous row, so the outlet pipe 81 can water the nutrient pots 5 after the cuttings are completed.

[0052] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
