Description

Technical Field

[0001] The present invention relates to the technical field of seedling support, and particularly to a fixing device for assisting the growth of municipal garden seedlings. Background Art

[0002] Municipal garden seedlings refer to plant materials used in municipal projects such as urban greening, parks, streets, squares, etc. These seedlings usually need to have strong adaptability, stress resistance and ornamental value to meet the needs of the urban environment. In the early stage of transplanting municipal garden seedlings, a fixing device is generally required to assist in supporting the seedlings. The support fixing device for seedlings is mainly used for the following aspects:

[0003] Protect seedlings from wind damage: The roots of newly transplanted seedlings are not yet fully fixed, and strong winds may cause the seedlings to tilt or fall. The support device can provide additional stability to prevent the seedlings from being blown down by the wind.

[0004] Promote root growth: By providing support, the shaking of the seedlings caused by external forces can be reduced, which is beneficial to the stability and growth of the roots, thereby improving the survival rate of the seedlings.

[0005] Beauty and neatness: The support device can keep the seedlings upright, maintaining the neatness and beauty of the landscape. Especially in crowded areas such as green spaces and parks, the neat layout of seedlings meets the ornamental requirements better.

[0006] Currently, most of the fixing devices are made of wood, with multiple pieces of wood built around the seedlings to provide circumferential support for the seedlings. The fixing device and the seedlings need to be fixed. However, after the fixing device and the seedlings are fixed, the following defects will occur:

[0007] 1. Since the seedlings are transplanted during the seedling and growth stages, at this production stage, the height growth rate of the seedlings is relatively fast. If the fixing device and the seedlings remain in a too tight state for a long time, it will limit the ability of the main trunk of the seedlings to grow upward. Especially during the rapid growth stage of the seedlings, since the fixing device and the seedlings are integrated at this time, and the fixing device is fixed to the ground, it will hinder the upward extension of the seedlings.

[0008] 2. Since the height of the fixing device is fixed, after the seedlings grow taller, the top part cannot be effectively supported, resulting in the seedlings bending or tilting due to lack of support.

[0009] 3. Although a fixing device with adjustable height can be used, and the height of the support frame can be gradually adjusted as the seedlings grow to avoid restricting the height growth of the seedlings, it requires manual adjustment regularly, which is too inconvenient. Summary of the Invention

[0010] In view of the above problems existing in the prior art, a fixing device for assisting the growth of municipal garden seedlings is proposed.

[0038] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0039] Example 1, referring to Figure 1-6, which is the first embodiment of the present invention, provides a fixing device for assisting the growth of municipal garden seedlings, including a seedling support mechanism for supporting and fixing seedlings. The seedling support mechanism includes: a plurality of support units arranged around the seedlings, and the lower ends of the support units are inserted and fixed in the ground; a fixing wire 1 for fixing the seedlings and the support units; the support unit further includes: an arc-shaped clamping block 2, and a rubber pad can be connected to the inner side wall of the clamping block 2 as a buffer between the clamping block 2 and the seedlings. The rubber pad on the inner side of the clamping block 2 is arranged against the side wall of the seedlings, and the fixing wire 1 fixes the clamping block 2 and the seedlings. The longitudinal growth rate of the seedlings is greater than the lateral growth rate. Therefore, in the early support stage of seedling transplantation, due to the compressible characteristic of the rubber pad, while meeting the lateral growth requirements of the seedlings, when the seedlings grow longitudinally, they will drive the clamping block 2 to move synchronously; a ground-attachment box 3, the outer bottom of the ground-attachment box 3 is connected with an insertion rod inserted in the ground, the box opening of the ground-attachment box 3 is clamped with a box cover, and a sliding seat 5 is connected to the inner box wall near the box opening of the ground-attachment box 3 in a limited sliding manner through two sliding rods 4. The upper end of the sliding seat 5 is connected with a balance block 6, and a transmission bar 7 is hinged between the balance block 6 and the clamping block 2; a one-way traveling component, connected to the lower end of the sliding seat 5 and located inside the ground-attachment box 3. The one-way traveling component includes a partition 8 connected to the inner box wall of the ground-attachment box 3. The lower end of the sliding seat 5 is elastically and limitably movably connected with a traveling seat 9 in the vertical direction through an upward pulling component, and the partition 8 is located below the traveling seat 9. Two tooth plates 10 are symmetrically connected to the upper end of the partition 8 with respect to the traveling seat 9. Tooth blocks 11 are movably connected to the two side walls of the traveling seat 9 close to the two tooth plates 10 through elastic components. The tooth blocks 11 are engaged with the corresponding tooth plates 10. The box opening of the ground-attachment box 3 is clamped with a box cover, and the box cover does not affect the movement of the balance block 6 and reduces the sundries falling into the ground-attachment box 3.

[0040] Specifically, the clamping block 2 on the support unit close to the seedlings is fixed through the fixing wire 1, so that the clamping block 2 and the seedlings are fixed. When the seedlings grow, the clamping block 2 moves upward. The clamping block 2 pulls the balance block 6 toward the seedlings through the hinged transmission bar 7 and drives the sliding seat 5 to slide on the sliding rod 4. While the sliding seat 5 moves toward the seedlings, it drives the traveling seat 9 to move synchronously. During the movement, the tooth block 11 is blocked by the inclined surface of the tooth plate 10 and compresses the elastic component multiple times, so that the traveling seat 9 and the sliding seat 5 can move normally without affecting the upward extension of the seedlings; when in bad weather and the seedlings are blown by strong winds, not only through multiple groups of support units distributed in a circular array, a good support and fixing effect on the seedlings can be achieved.

[0041] Refer to Figure 6, the elastic component includes an elastic groove 12 formed on the side wall of the traveling seat 9. The bottom of the elastic groove 12 is connected with an elastic reset member 13, and the other end of the elastic reset member 13 is connected with the tooth block 11. The elastic reset member 13 can be a spring. The tooth block 11 is connected to the elastic groove 12 in a limited sliding manner, and the end of the tooth block 11 away from the elastic reset member 13 is arranged through the elastic groove 12. A roller is rotatably connected to the inclined surface of the tooth block 11 to reduce the frictional resistance when the tooth block 11 and the tooth plate 10 move relative to each other.

[0042] Specifically, when the seedlings grow upward, they will pull the traveling seat 9 towards the seedlings. During the movement, after the tooth block 11 is pressed by the inclined surface of the tooth plate 10, the tooth block 11 compresses the elastic reset member 13 and moves into the elastic groove 12, so that the traveling seat 9 can move normally towards the seedlings, and through the tooth block 11 meshing with the tooth plate 10, the tooth block 11 and the traveling seat 9 cannot move backward.

[0043] Refer to Figure 1-9 , the support unit further includes a return member installed on the traveling seat 9. The return member includes return rods 15 symmetrically connected to the side walls of both sides of the traveling seat 9, and the return rods 15 are located directly below the tooth block 11. Return grooves 16 are formed on the side wall of the tooth plate 10 close to the traveling seat 9 at positions corresponding to the return rods 15. The ends of the return rods 15 away from the traveling seat 9 extend into the return grooves 16 movably. The return grooves 16 include an upward running groove 161, a downward inclined arc groove 162, a downward return groove 163, and an upward rising groove 164 that are connected in sequence. The upward running groove 161 and the downward return groove 163 are arranged in parallel, the downward inclined arc groove 162 is inclined, and the length of the upward running groove 161 is shorter than the length of the downward return groove 163.

[0044] Specifically, when the fixing device completes the task and no longer needs to assist in supporting the seedlings, when the fixing device is removed from the seedlings and it is necessary to return the sliding seat 5 and the traveling seat 9 to the starting point (the maximum value away from the seedlings), a driving force is applied to the sliding seat 5 in the direction close to the seedlings when supporting the seedlings. The return rod 15 on the traveling seat 9 driven by the sliding seat 5 is first in the upward running groove 161 of the return groove 16, and then the return rod 15 enters the downward return groove 163 through the downward inclined arc groove 162. In this stage, the upward pulling component is stretched. Then, a pulling force is applied to the sliding seat 5 again, so that the return rod 15 reaches the connection point of the downward return groove 163 and the upward rising groove 164. Under the action of the reset force of the upward pulling component, the return rod 15 enters the upward running groove 161 through the upward rising groove 164 again.

[0045] Refer to Figure 1-8, the upper pulling component includes two upper pull rods 17 symmetrically connected to the upper end of the traveling seat 9. Two upper pull slots 18 are symmetrically opened at the lower end of the sliding seat 5. One end of the upper pull rod 17 away from the traveling seat 9 extends into the corresponding upper pull slot 18 movably. The upper pull rod 17 is in limit sliding connection with the upper pull slot 18. An upper pull return member 19 is sleeved on the upper pull rod 17 between the traveling seat 9 and the sliding seat 5. The upper pull return member 19 can be a spring, and both ends of the upper pull return member 19 are connected to the traveling seat 9 and the sliding seat 5 respectively.

[0046] Specifically, the sliding seat 5 and the traveling seat 9 are connected by the upper pull rod 17. When the sliding seat 5 is horizontally pushed, the traveling seat 9 is pulled by the upper pull rod 17 to move horizontally synchronously. When the traveling seat 9 moves obliquely downward, that is, when the return rod 15 slides in the lower inclined arc slot 162, the traveling seat 9 pulls the upper pull rod 17 to move downward in the upper pull slot 18 and stretches the upper pull return member 19. When the return rod 15 moves to the connection point of the lower return slot 163 and the rising slot 164, under the action of the deformation reset force of the upper pull return member 19, the traveling seat 9 is pulled upward, so that the return rod 15 enters the upper traveling slot 161 from the rising slot 164.

[0047] During use, the clamp block 2 on the support unit against the seedlings is fixed by the fixing wire 1, so that the clamp block 2 and the seedlings are fixed. When the seedlings grow upward, the clamp block 2 moves upward. The clamp block 2 drives the balance block 6 to move toward the seedlings through the hinged transmission bar 7 and drives the sliding seat 5 to slide on the sliding rod 4. While the sliding seat 5 moves toward the seedlings, the traveling seat 9 is driven by the upper pulling component to move synchronously. During the movement, after the tooth block 11 is pressed by the inclined surface of the toothed plate 10, the tooth block 11 compresses the elastic return member 13 and moves into the elastic slot 12, so that the traveling seat 9 can move normally toward the seedlings. And through the tooth block 11 meshing with the toothed plate 10, the tooth block 11 and the traveling seat 9 cannot move backward, so that the traveling seat 9 and the sliding seat 5 can move normally without affecting the upward extension of the seedlings. When in bad weather and the seedlings are blown by strong wind, not only through multiple groups of support units distributed in a circular array, a good support and fixation effect on the seedlings is achieved.

[0048] When it is necessary to return the sliding seat 5 and the traveling seat 9 to the starting point, a pushing force toward the seedlings is applied to the sliding seat 5. The return rod 15 on the traveling seat 9 driven by the sliding seat 5 is first in the upper traveling slot 161 of the return slot 16, and then the return rod 15 enters the lower return slot 163 through the lower inclined arc slot 162. In this stage, the traveling seat 9 pulls the upper pull rod 17 to move downward in the upper pull slot 18 and stretches the upper pull return member 19. Then a pulling force is applied to the sliding seat 5 again, so that the return rod 15 reaches the connection point of the lower return slot 163 and the rising slot 164. Under the action of the deformation reset force of the upper pull return member 19, the traveling seat 9 is pulled upward, so that the return rod 15 enters the upper traveling slot 161 from the rising slot 164.

[0049] Example 2. Refer to Figure 5 and Figure 10 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that when a single fallen seedling is supported, a single support unit can be used in the falling direction of the seedling. After the seedling is righted, the clamping block 2 of the support unit and the seedling are fixed together through a fixing wire. Under normal circumstances, the tooth block 11 cannot retreat on the toothed plate 10, so as to ensure that the support unit can support the fallen seedling.

[0050] Example 3. Refer to Figure 1-8 , which is the third embodiment of the present invention. The difference between this embodiment and the first embodiment is that the support unit further includes a fertilizing component installed in the ground contact box 3. The fertilizing component includes a replacement opening 20 opened at the bottom of the box at the position of the ground contact box 3 away from the seedling. A matching replacement plate 21 is hermetically and slidably connected in the replacement opening 20. A plurality of liquid storage bags 22 filled with nutrient solution are arranged on the inner bottom of the ground contact box 3. The nutrient solution includes but is not limited to liquid fertilizer. An extraction opening is opened at one end of the ground contact box 3 close to the seedling. A plug 23 is plugged in the extraction opening. One end of the plug 23 close to the liquid storage bag 22 is connected with a bag-breaking needle 24, and the other end of the bag-breaking needle 24 extends into the ground contact box 3. A liquid outlet component is installed at the bottom of the ground contact box 3. A bag-pushing assembly for pushing the liquid storage bag 22 to move is arranged at the lower end of the traveling seat 9. The liquid outlet component includes a liquid outlet hole opened at the bottom of the ground contact box 3. A ball chamber 25 is rotatably connected in the liquid outlet hole in a damping manner. The lower end of the ball chamber 25 is communicated with a liquid outlet pipe 26. The liquid outlet pipe 26 can drive the ball chamber 25 to rotate in the liquid outlet hole. During the seedling transplanting stage, the orientation of the liquid outlet pipe 26 is adjusted according to the position of the seedling root, so that the liquid outlet of the liquid outlet pipe 26 is close to the seedling root, and then the soil is buried. When the fixing device is removed, the plug 23 together with the bag-breaking needle 24 is taken out from the extraction opening, and the liquid storage bag 22 on the bag-breaking needle 24 is removed. It should be noted that the fertilizing time period of the fertilizing component for the seedlings is mainly during the period when the seedlings re-root in the new soil after transplantation. Therefore, not all of the multiple liquid storage bags 22 filled with nutrient solution in the ground contact box 3 will be used, and the remaining unused liquid storage bags 22 can be reserved for the next use of the fixing device. Therefore, the push plate 14 and the bag-breaking needle 24 will not intersect; when the fixing device needs to be reset, first remove the fixing device from the seedling and pull it out of the soil, then open the replacement plate 21, take out the remaining liquid storage bags 22 after use, and then take out the plug 23 together with the bag-breaking needle 24 from the ground contact box 3. At this time, the traveling seat 9 can move in the direction close to the seedling when it originally assisted in supporting the seedling, so that the sliding seat 5 and the traveling seat 9 return to the starting point.

[0051] Specifically, when the seedlings extend and grow upward, the traveling seat 9 pushes the liquid storage bag 22 toward the direction of the bag piercing needle 24 through the bag pushing assembly. The bag piercing needle 24 pierces the liquid storage bag 22, and the nutrient solution in the liquid storage bag 22 leaks out and is discharged through the liquid outlet pipe 26 to fertilize the roots of the seedlings. In the seedling transplanting stage, first open the bag changing plate 21, add the liquid storage bag 22 to the Adong ground box 3, and then slide the bag changing plate 21 into the bag changing port 20.

[0052] Reference Figure 1-8 The bag pushing assembly includes a long pushing slot 30 opened on the partition 8, and two compensation parts are symmetrically installed on the side wall of the traveling seat 9. The two compensation parts pass through the pushing slot 30 and are jointly installed with a pushing plate 14. The pushing plate 14 is movably abutted against the liquid storage bag 22 away from the seedlings. The compensation part includes a compensation ring 27 connected to the side of the pushing plate 14 away from the liquid storage bag 22. A compensation rod 28 is movably passed through the compensation ring 27, and one end of the compensation rod 28 passes through the pushing slot 30 and is set on the side wall of the traveling seat 9.

[0053] Specifically, when the traveling seat 9 moves, it drives the compensation rod 28 to move synchronously in the pushing groove 30, and then pushes the push plate 14 to move synchronously through the compensation ring 27, thereby pushing the liquid storage bag 22; when the traveling seat 9 is adjusted in height position, the compensation rod 28 moves vertically in the compensation ring 27 without affecting the push of the push plate 14.

[0054] Reference Figure 5 A plurality of petal-shaped bag-supporting pieces 29 are evenly distributed in a ring shape on the needle wall near the needle head of the bag-breaking needle 24; the inner box bottom of the ground-contacting box 3 near the liquid outlet is arranged as an inclined surface facing the liquid outlet, and the liquid storage bag 22 is arranged closely to the inner box wall of the ground-contacting box 3.

[0055] Specifically, the broken liquid storage bag 22 is pried open from the punctured opening by the bag-opening piece 29 , so that the nutrient solution in the liquid storage bag 22 flows out and then is collected toward the liquid outlet through the inner bottom slope of the ground-contacting box 3 .

[0056] During use, when the seedlings extend and grow upward, the traveling seat 9 drives the compensation rod 28 to move synchronously in the pushing groove 30, and then pushes the push plate 14 to move synchronously through the compensation ring 27, thereby pushing the liquid storage bag 22. The bag-breaking needle 24 pierces the liquid storage bag 22, and the broken liquid storage bag 22 is opened from the punctured hole through the bag-supporting piece 29, so that the nutrient solution in the liquid storage bag 22 flows out, and then flows to the liquid outlet pipe 26 through the inner box bottom inclined surface of the ground-attached box 3, and is discharged through the liquid outlet pipe 26 to fertilize the roots of the seedlings. The punctured liquid storage bag 22 remains on the bag-breaking needle 24.

[0057] Combining Embodiment 1 and Embodiment 3, the working principle of the present invention is as follows: The clamping block 2 on the support unit against the seedlings is fixed by the fixing steel wire 1, so that the clamping block 2 and the seedlings are fixed. When the seedlings grow upward, the clamping block 2 moves upward. The clamping block 2 drives the balance block 6 to move towards the seedlings by the hinged transmission bar 7, and drives the sliding seat 5 to slide on the sliding rod 4. While the sliding seat 5 moves towards the seedlings, the traveling seat 9 is driven to move synchronously by the upper pulling assembly. During the movement, after the tooth block 11 is subjected to the pressure of the inclined surface of the tooth plate 10, the tooth block 11 compresses the elastic reset member 13 and moves into the elastic groove 12, so that the traveling seat 9 can move normally towards the seedlings, and through the tooth block 11 meshing with the tooth plate 10, the tooth block 11 and the traveling seat 9 cannot move backward, so that the traveling seat 9 and the sliding seat 5 can move normally without affecting the upward extension of the seedlings. When in bad weather and the seedlings are blown by strong wind, not only a plurality of groups of support units distributed in a circular array play a good role in supporting and fixing the seedlings.

[0058] When the traveling seat 9 moves towards the seedlings, it also drives the compensation rod 28 to move synchronously in the pushing groove opening 30, and then drives the push plate 14 to move synchronously through the compensation ring 27, so as to realize the pushing of the liquid storage bag 22. The bag-breaking needle 24 pierces the liquid storage bag 22, and the broken liquid storage bag 22 is opened from the piercing opening by the bag-supporting piece 29, so that the nutrient solution in the liquid storage bag 22 flows out, and then flows to the liquid outlet pipe 26 through the inner box bottom inclined surface of the ground-attached box 3 and is discharged through the liquid outlet pipe 26 to fertilize the roots of the seedlings. The punctured liquid storage bag 22 remains on the bag-breaking needle 24.

[0059] When the fixing device completes the task and no longer needs to assist in supporting the seedlings, when the fixing device is removed from the seedlings and it is necessary to return the sliding seat 5 and the traveling seat 9 to the starting point, a driving force in the direction close to the seedlings when supporting the seedlings is applied to the sliding seat 5. The return rod 15 on the traveling seat 9 driven by the sliding seat 5 is first in the upper running groove 161 of the return groove 16, and then the return rod 15 enters the lower return groove 163 through the lower inclined arc groove 162. During this stage, the traveling seat 9 pulls the upper pull rod 17 to move downward in the upper pull groove 18 and stretches the upper pull reset member 19. Then, a return pulling force is applied to the sliding seat 5, so that the return rod 15 reaches the connection point of the lower return groove 163 and the rising groove 164. Under the action of the deformation reset force of the upper pull reset member 19, the traveling seat 9 is pulled upward, so that the return rod 15 enters the upper running groove 161 from the rising groove 164.
