Description

Technical Field

[0001] The invention relates to the technical field of Acer truncatum planting, and in particular to a water and fertilizer management test system for Acer truncatum seedlings. Background Art

[0002] Acer truncatum is not only an important afforestation tree species in ecologically fragile areas, but also an excellent tree species for urban greening and street trees. In recent years, Acer truncatum has attracted attention for its high-quality neuraminic acid content in its seed oil. Because the neuraminic acid in Acer truncatum seed oil has a good effect on the prevention and repair of neurological diseases such as cerebral stroke and Alzheimer's disease. In order to develop the excellent characteristics of Acer truncatum, it was found that water and fertilizer management of Acer truncatum seedlings is the key in the process of cultivating varieties with high fruit yield and high neuraminic acid content. However, the existing water and fertilizer management often causes uneven distribution or waste of nutrients. The main reason is that the amount and depth of fertilizer application are not well controlled, which in turn affects the nutrient utilization efficiency and growth quality of Acer truncatum seedlings.

[0003] In view of the above, we provide a water and fertilizer management test system for Acer truncatum seedlings to solve the above problems. Summary of the invention

[0004] In view of the above situation, the present invention provides a water and fertilizer management test system for Acer truncatum seedlings. The system has a downward pressure frame that can be pressed down and released. During the downward pressure process, the inserted leaves are inserted into the soil synchronously. When the downward pressure frame is released, the inserted leaves can be driven to rotate, thereby opening the internal soil and opening the valve plate to facilitate the transportation of fertilizer to the interior. The striking frame is synchronously controlled to rebound to the upper end of the soil to compact the fertilization position.

[0005] A water and fertilizer management test system for Acer truncatum seedlings, comprising a frame, a rotatable rotating frame is rotatably provided on the upper surface of the frame, a lower pressure frame is slidably provided on the rotating frame, an insertion fertilizer mechanism is provided at the bottom of the lower pressure frame, the insertion fertilizer mechanism comprises an insertion leaf, a storage bottle and a conveying rod, the insertion leaf is rotatably provided on one side of the lower pressure frame, a driving mechanism is provided on one side of the rotating frame, the driving mechanism comprises a driving rod, a rotating shaft and a striking frame, the driving rod is slidably provided on one side of the rotating frame, a through hole through which the driving rod can pass is provided on the edge of the insertion leaf, a one-way block is rotatably provided on one side of the insertion leaf, a cross bar is slidably provided on one side of the lower pressure frame, and the bottom of the striking frame is provided on a spray control mechanism.

[0006] The above technical solution has the following beneficial effects:

[0007] The downward pressure frame provided in the present scheme can be pressed down and released, and during the process of pressing down, the inserted leaves are inserted into the soil synchronously. The releasing of the downward pressure frame can drive the inserted leaves to rotate, thereby expanding the internal soil and opening the valve plate, so as to facilitate the transportation of fertilizer to the inside. The striking frame is synchronously controlled to rebound to the upper end of the soil, so that the fertilization position is compacted, and the striking frame can transport liquid to the bottom of the plant for spraying and maintenance. The jacking frame can also be moved upward to control the water pressure of the nozzle and change the nozzle spraying position, so that the nozzle can spray liquid along both sides and change the nozzle spraying direction.

DETAILED DESCRIPTION

[0017] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 8It can be clearly presented in the detailed description of the embodiments that the structural contents mentioned in the following embodiments are all referenced to the drawings in the specification.

[0018] This embodiment provides a water and fertilizer management test system for Acer truncatum seedlings, as shown in the attached Figure 1-4 As shown, in order to prevent the influence of rain on plants, the frame 1 of this scheme needs to be placed in a movable rain shelter, which can be moved to block rain. The placement table can be set as a weighing system, which can be connected to each flower pot for weighing at any time. The rotating frame 2 rotates 90 degrees each time to dig a small hole with a depth of 7 cm in each of the four directions of the flower pot (about 2 cm away from the edge of the pot), and then the fertilizer is put in by inserting the leaf. The instruction manual is attached. Figure 1 This is the front view of the scheme, and the general structure of the scheme can be seen. Figure 2 The three-dimensional structure diagram of the frame 1 is attached to the instruction manual. Figure 3 This is a separate structural diagram of the rotating frame 2. As shown in the figure, the structure of the rotating frame 2 is concentrated at one end of the rotating frame 2, because the specification is attached. Figure 3 The structure is concentrated at the top, so Figure 3 A wavy line is shown in the figure to separate the concentrated part. Figure 4 It is the extension of this wavy line that shows the part of the rotating frame 2. Figure 4 At the beginning, the rotating frame 2 is shown alone, and the frame body 1 is not shown. The rotating frame 2 is a main structure of the present invention, which can be rotatably arranged on the surface of the frame body 1 and can rotate around the surface of the frame body 1. The edge of the rotating frame 2 is a gear ring, and a driving gear is rotatably arranged on the edge of the frame body 1. A motor can be installed at the bottom of the driving gear, and the motor drives the driving gear to rotate, so as to achieve the effect of rotating the rotating frame 2. Figure 4 As shown, there is a lower pressing frame 3 sliding vertically below the rotating frame 2, and an insertion leaf 4 is rotatably arranged on one side of the lower pressing frame 3. The insertion leaf 4 can move up and down on the lower pressing frame 3, and the insertion leaf 4 is not a part that can move up and down by itself, as shown in the attached manual. Figure 6The hopper 3 is provided with a telescopic rod, which is fixedly arranged on the rotating frame 2, and the telescopic rod is the electric push rod in the prior art. The push rod can control the bottom hopper 3 to move up and down. This is the moving trajectory of the hopper 3. The hopper 3 in the attached drawings of this scheme is all at the top and has not moved downward. An insertion leaf 4 is rotatably arranged on one side of the hopper 3. The insertion leaf 4 and the bottom of the hopper 3 form a sharp shape, which can be inserted into the soil to facilitate the transportation of fertilizer into the soil. The first effect of this scheme is fertilization. The hopper 3 and the insertion leaf 4 are responsible for inserting into the soil during the downward movement. When they reach a certain position, the fertilizer can be automatically transported between the two. A cross bar 12 is arranged on one side of the hopper 3 for horizontal sliding. The cross section of the cross bar 12 may not be a circular shape to prevent the cross bar 12 from rotating on the surface of the hopper 3. The cross bar 12 can only slide horizontally on one side of the hopper 3 and cannot rotate. There is a spring between the cross bar 12 and the hopper 3 to maintain the position, as shown in the attached manual. Figure 4As shown, there is a spring between the cross bar 12 and the downward pressure (most of the springs in this solution are numbered, only some small springs are not numbered). This spring enables the cross bar 12 to maintain its position. Once the cross bar 12 slides to one side, the spring can reset the cross bar 12 without external force. This is the function of the spring. In the figure, all the springs of this solution are in their original length state. One side of the cross bar 12 is a sliding overlap block 14, which can be compressed and slid once on the cross bar 12. There is also a spring between the two, which allows the overlap block 14 to extend. The overlap block 14 is chamfered and can be reset to the middle of the driving rod 7 again. The other side of the rod 12 is an integrally arranged cylinder, the position of which corresponds to the entrance of the lap groove 15, that is, the lower pressing frame 3 is driven by the electric push rod to move the cross bar 12 downward synchronously. When it has not entered the lap groove 15, one side of the cross bar 12 is driven to move along the line through the lap block 14. When one side of the cross bar 12 enters the lap groove 15, it is driven by the lap groove 15 to move the cross bar 12 toward one side of the rotating frame 2, so that the cross bar 12 drives the lap block 14 to disengage from the driving rod 7, and a main spring 13 is provided on the top of the driving rod 7, which keeps pressing the driving rod 7 during the downward movement. The above-mentioned cross bar 12 once detaches from the driving rod 7 driven by the lap groove 15, the driving rod 7 will quickly reset upwards driven by the main spring 13. This scheme uses this segment to be set on the insertion leaf 4. At this time, the insertion leaf 4 and the lower pressure frame 3 are both inserted into the soil. Because the cross bar 12 makes the lap block 14 detach from the driving rod 7, the driving rod 7 is quickly reset under the drive of the main spring 13. The driving rod 7 will cause the insertion leaf 4 to rotate during the resetting process, because there is an inclined strip on one side of the insertion leaf 4, and this inclined strip is set on the insertion leaf 4, and has a through hole 10 and a one-way block 11. The one-way block 11 is rotatably set on one side of the insertion leaf 4. The significance of the existence of the one-way block 11 is that one side of the driving rod 7 can pass through the through-hole 10 from top to bottom, but the driving rod 7 cannot reach the through-hole 10 from bottom to top. Under the guidance of the one-way block 11, one side of the driving rod 7 passes through one side of the insertion leaf 4, causing the insertion leaf 4 to rotate. The rotation of the insertion leaf 4 can make the lower pressure frame 3 inserted into the soil and the bottom of the insertion leaf 4 open, making it convenient for the fertilizer to reach the bottom, that is, the function of the driving rod 7 is to make the insertion leaf 4 rotate, making it convenient for the fertilizer to reach the inside of the soil. It needs to be introduced here that in order to enable the insertion leaf 4 to operate stably, torsion springs should be arranged on both sides of the insertion leaf 4. Under the action of the torsion springs, the insertion leaf 4 is in the shape of a circle as shown in the attachment of the instruction manual Figure 4As shown, it forms a sharp shape with the lower pressure frame 3, but the elastic force of this torsion spring is much smaller than the elastic force of the main spring 13, so that the insertion leaf 4 can be reset after rotating around the lower pressure frame 3, and when the driving rod 7 is reset by the main spring 13, it will reach the insertion leaf 4 for rotation. After rotation, the insertion leaf 4 is rotated and reset by the torsion spring. This is one of the core points of this solution, that is, after reaching a certain depth, the driving rod 7 can be released, so that the driving rod 7 can rise quickly, so as to achieve the effect that the insertion leaf 4 rotates first and then resets. The rotation of the insertion leaf 4 can increase the expanded soil space, facilitate the entry of fertilizer, and release the fertilizer by controlling it, because a valve plate 16 is slidably arranged at the bottom of the conveying rod 6, and the valve plate 16 is attached to the instruction manual. Figure 7 It is shown in the figure that the valve plate 16 just blocks the top of the conveying rod 6, so that the fertilizer cannot be discharged. The insertion leaf 4 introduced above will rotate under the drive of the driving rod 7, so the insertion leaf 4 will move toward the valve plate 16, which can push the valve plate 16 to move. There is a corresponding circular hole on one side of the valve plate 16, so the moving valve plate 16 makes the conveying rod 6 discharge the fertilizer, achieving the effect of fertilizer discharge and the opening of the insertion leaf 4. The conveying rod 6 is fixedly set on the lower pressure frame 3, and the storage bottle 5 is used to store fertilizer. The conveying rod 6 is sealed and slidably set at the bottom of the conveying bottle. When the conveying rod 6 moves downward, it will block the bottom of the storage bottle 5. When the conveying rod 6 moves upward, it will automatically allow the fertilizer to enter along the inside, achieving the effect of moving up and down to take and put in materials;

[0019] As attached Figure 5-8 As shown in the instruction manual, Figure 5 Another perspective of the rotating frame 2, mainly showing the nozzle 24, the instruction manual is attached Figure 6 The middle of the local rotating frame 2 was temporarily cut, and the instructions are attached. Figure 7 and 8 All are cited in the appendix of the manual Figure 6The previous paragraph introduced that the driving rod 7 will be released when it reaches the position, and this paragraph introduces other effects of the driving rod 7. The side setting of the driving rod 7 can also cooperate with the tooth groove of the rotating shaft 8, so the driving rod 7 is reset upward to make the rotating shaft 8 rotate (a touch rod 23 is rotated on one side of the striking frame 9, which can move water on the leaves to the lower layer during the up and down movement. In order to prevent damage to the plants, a sponge or a brush is provided on one side of the touch rod 23, and the rotation angle of the touch rod 23 is less than ninety degrees). The rotation of the rotating shaft 8 can make the striking frame 9 reset downward. This paragraph introduces the effect of the striking frame 9. The striking frame 9 is vertically slidably arranged on one side of the storage bottle 5. Because the inserted leaf 4 has been rotated and unfolded in the previous step, the soil is inserted into the leaf at this time. 4 is moved to one side, and the fertilizer cannot be compacted, so the striking frame 9 rebounds quickly to compact the soil at this position. In order to make this effect obvious, this solution is provided with a bottom block 20 on the surface of the striking frame 9. The bottom block 20 is also designed with sharp chamfers, which can also push the soil along one side of the inserted leaf 4. The bottom block 20 is slidably arranged at the bottom of the striking frame 9, and a return spring 21 is arranged between the two. This solution is also an infusion mechanism. The infusion passes through the main pipe 17. One end of the main pipe 17 needs to be connected to a water pump, which needs to be placed in a water tank. Because the water pump belongs to the prior art, this solution does not show the water pump, but only explains that one side of the main pipe 17 needs to be connected to water, and the liquid needs to be sprayed under the intervention of the water pump. The other end of the main pipe 17 is connected to a branch. The first pipe 18 and the second pipe 19, that is, the main pipe 17, the first pipe 18 and the second pipe 19 form a three-way connection. The main pipe 17 can supply water to the first pipe 18 and the second pipe 19 at the same time. The first pipe 18 is connected to the striking frame 9. A bottom block 20 is arranged between the first pipe 18 and the nozzle 22 of the striking frame 9. The top of the bottom block 20 acts as a valve. When the bottom block 20 moves upward, the passage between the two is opened, so that the first pipe 18 can reach the nozzle 22 to spray water. This is all the characteristics of the striking frame 9. The first pipe 18 and the second pipe 19 can both be hoses. Finally, the nozzle 24 of this scheme is introduced. The nozzle 24 of this scheme is connected and arranged at one end of the second pipe 19. The nozzle 24 can be rotated on one side of the storage bottle 5. One side of the nozzle 24 is arranged There is a torsion spring 27 for rotational reset, and the nozzle 24 can be rotated by the top frame at the bottom. Because the lifting frame 28 is slidably arranged on one side of the storage bottle 5, the driving rod 7 is reset and the lifting frame 28 is driven to move upward at the same time. The upward movement of the lifting frame 28 can drive the nozzle 24 to rotate, thereby achieving the effect of adjusting the direction. The main spring 13 of this scheme is larger than all springs, but one side of the nozzle 24 has other effects. One side of the nozzle 24 is softly connected to the upper and lower hard plates 26. The soft edge 25 is between the two hard plates 26. The soft edge 25 is also soft, and the position of the lifting frame 28 corresponds to the hard plate 26 at the lower position. Because the torsion spring 27 has a certain elastic force, the lower hard plate 26 is first controlled to rotate (the hard plate 26 is softly connected,Therefore, it can be rotated on one side of the nozzle 24), the lower hard plate 26 will contact the upper hard plate 26, and the two sets of plates contact to form a seal, which is equivalent to an increase in the outlet on one side of the nozzle 24, which is equivalent to an increased water pressure while the water pump is delivering. The nozzle 24 rotates to spray on the top of the plant. The increased water pressure corresponds to the top of the plant, and the nozzle 24 will spray liquid along both sides to achieve the effect of changing the spraying direction of the nozzle 24. This is the effect of the nozzle 24 being provided with a hard plate 26 and a soft edge 25.
