Description

Technical Field

[0001] The invention relates to the technical field of forestry planting, in particular to a poplar seedling supporting device. Background Art

[0002] Poplar is a plant of the genus Populus, with a usually straight trunk; the bark is smooth or longitudinally cracked, and is often grayish white. After the poplar seedlings are planted or transplanted, the roots have not yet extended. In order to prevent them from tilting under the action of external forces and to ensure their survival rate, seedling support racks are often used after planting to assist the growth of the seedlings, improve their survival rate, and make the growth angle of the seedlings ideal.

[0003] When supporting poplar seedlings after planting, existing devices usually use vertical poles to support the outer surface of the poplar seedlings. However, the poplar seedlings are in a vertical shape as a whole, so long columns are needed to achieve effective support. The long columns form a sufficiently large angle with the ground to ensure stable support, and the area occupied by the poles will be expanded accordingly. Once the ground space cannot meet the required range of the pole support, the pole support angle will be too small, the supporting force will be significantly weakened, and it will be difficult to stably support the poplar seedlings. In addition, the long poles are extremely inconvenient to store and carry. Therefore, a poplar seedling support device that occupies a small area and is easy to store is needed.

Before installing the clamping component 36, it is necessary to stretch the folding rod 4 to a suitable height. When the clamping component 36 is placed on the clamping block 34, the rotating shaft 304 at the bottom of the folding rod 4 can be limited to prevent the rotating shaft 304 from rotating, so that the top end of the folding rod 4 can be installed on the second group of clamping components 36 through the connecting piece 42, so as to support the two outer points of the poplar sapling in a vertical state, and prevent the poplar sapling from bending and tipping over.

[0041] First, considering the problem of how the connecting plate 22 is rotated, Figure 2-Figure 5, the specific structure of the rotating component 21 is disclosed. The rotating component 21 includes a polygonal socket 201 opened on the outer surface of the connecting block 2, and a polygonal plug 202 is inserted into the interior of the polygonal socket 201.

[0042] Furthermore, the connecting plate 22 is hinged inside the connecting block 2, and a through polygonal socket 201 is provided between the connecting plate 22 and the outside of the connecting block 2, so that the polygonal plug 202 can be plugged into the inside of the polygonal plug 201, and then the connecting plate 22 is limited and fixed inside the connecting block 2. When the device is not in use, the polygonal plug 202 can be pulled out to make the connecting plate 22 fall toward the middle of the base 1, and the polygonal plug 202 is inserted to store the connecting plate 22. When the poplar seedling needs to be supported, the polygonal plug 202 is pulled out to rotate the connecting plate 22 to an angle perpendicular to the base 1, and then the polygonal plug 202 is inserted into the inside of the polygonal socket 201 to limit and fix the connecting plate 22, so as to achieve the effect of limiting and fixing the connecting plate 22 after rotation. The device can be conveniently stored and carried.

[0043] Secondly, considering the problem of how the connecting rod 3 moves up and down outside the connecting plate 22, Figure 2 and Figure 3 , the specific structure of the adjustment component 31 is disclosed. The adjustment component 31 includes a threaded hole 1 opened on the top of the connecting plate 22. The internal thread of the threaded hole 1 is connected with a threaded column 3101. The bottom of the threaded column 3101 passes through the connecting plate 22 and the connecting rod 3 and extends to the bottom of the inner wall of the slide groove. The connecting rod 3 can move up and down along the threaded column 3101.

[0044] Two connecting plates 22 and two connecting rods 3 are provided, and the two connecting plates 22 and the connecting rods 3 are symmetrically distributed on the top of the base 1 .

[0045] Furthermore, by inserting the outer side of the connecting rod 3 into the slide groove opened on the outer side of the connecting plate 22, a threaded hole 1 is opened at the top of the connecting plate 22, which passes through the connecting plate 22 and the connecting piece 42 in the slide groove of the connecting plate 22, so that the threaded column 3101 can be threadedly connected to the bottom of the inner wall of the slide groove through the threaded hole 1. The person rotates the top of the threaded column 3101, and the threaded rod 501 is a reciprocating screw, so that the connecting piece 42 can move up and down along the rotating threaded column 3101, so as to achieve the effect of adjusting the height of the connecting piece 42 up and down. The two connecting plates 22 are symmetrically distributed on the top of the base 1, and the two connecting rods 3 can be adjusted, and the bottom sides of the clamping assembly 36 can be docked and installed.

[0046] Again, considering the problem of how to install and clamp the poplar seedlings with the clamping assembly 36, Figure 2-Figure 6, the specific structures of the clamping assembly 36 and the fixing assembly 5 are disclosed, the clamping assembly 36 includes an annular hinge sleeve 301, a card interface 302 is provided at the bottom of the annular hinge sleeve 301, a card block 34 is carded inside the card interface 302, and is used to fix the position of the annular hinge sleeve 301, a docking interface 303 is provided at the top of the annular hinge sleeve 301, a rotating shaft 304 is fixedly installed at the bottom of the folding rod 4, the rotating shaft 304 is hinged inside the connecting sleeve 35, a plurality of docking blocks 305 are fixedly installed on the outer surface of the rotating shaft 304, the docking blocks 305 are carded inside the docking interface 303, and are used to limit the rotation angle of the folding rod 4, and a fixing assembly 5 is arranged inside the annular hinge sleeve 301.

[0047] The fixing assembly 5 includes a threaded hole 2 opened on the outer surface of the annular hinge sleeve 301, the inner thread of the threaded hole 2 is connected with a threaded rod 501, one end of the threaded rod 501 passes through the annular hinge sleeve 301 and extends to the inside of the annular hinge sleeve 301, one end of the threaded rod 501 is rotatably connected with an arc plate 502, a plurality of buffer springs 503 are installed on the inner wall of the arc plate 502, and an extrusion plate 504 is installed at one end of the plurality of buffer springs 503 away from the arc plate 502, and the extrusion plate 504 is used to clamp the outer surface of the poplar seedling. Two fixing assemblies 5 are provided, and the two fixing assemblies 5 are symmetrically distributed inside the annular hinge sleeve 301, and are used to clamp both sides of the outer surface of the poplar seedling.

[0048] Furthermore, by setting the annular hinge sleeve 301 to open and close, the annular hinge sleeve 301 can be opened and closed and placed on the outer surface of the poplar seedling, and the clamping block 34 is pressed downward, so that the sliding block 32 and the clamping block 34 squeeze the extrusion spring 37 downward along the fixed rod 33, so that the clamping interface 302 opened at the bottom of the annular hinge sleeve 301 can be connected to the clamping block 34, and the clamping block 34 is released, the extrusion spring 37 is reset, and the arc-shaped hinge sleeve is squeezed upward, so that the docking interface 303 opened at the top of the annular hinge sleeve 301 can be connected to the docking block 305 opened on the outer surface of the adjusting shaft 304, and then the folding rod 4 stretched to a suitable height is limited and fixed, so that the shaft 304 at the bottom of the folding rod 4 no longer rotates, and the arc-shaped hinge sleeve is installed and limited.

[0049] When supporting the poplar seedlings, the annular hinge sleeve 301 is sleeved on the outer surface of the poplar seedlings. The threaded rod 501 can be rotated to move the arc plate 502 and the extrusion plate 504 inside the arc hinge sleeve toward the outer surface of the poplar seedlings. The extrusion plate 504 finally fits the outer surface of the poplar seedlings to clamp and limit the poplar seedlings. The two extrusion plates 504 squeeze and support the two sides of the outer surface of the poplar seedlings at the same time, so as to achieve the effect of supporting and fixing the poplar seedlings. A buffer spring 503 is arranged between the extrusion plate 504 and the arc plate 502 to prevent the extrusion plate 504 from squeezing the poplar seedlings too tightly and causing damage to the epidermis of the poplar seedlings.

[0050] Finally, considering how to install another set of clamping components 36 at the top of the folding rod 4, the following is shown. Figure 7 and Figure 8 A plug-in block 6 is fixedly installed on the top of the connecting member 42, and the plug-in block 6 is used to install another set of clamping components 36 on the top of the connecting member 42.

[0051] By installing the ball joint 41 on the top of the folding rod 4, the connecting piece 42 can be spherically hinged, so that the plug-in block 6 on the top of the connecting piece 42 can adjust the angle, and the bottom clamping interface 302 of the annular hinge sleeve 301 of another group of clamping components 36 is docked. The two folding rods 4 are symmetrically distributed, and the clamping interfaces 302 on both sides of the bottom of the clamping components 36 are docked, and the clamping components 36 are installed and limited. The two groups of clamping components 36 then clamp and limit the two outer surface points of the poplar seedlings, so as to achieve a more stable effect of supporting the poplar seedlings;

[0052] It should be noted that the folding part of the folding rod 4 is also connected with a polygonal plug-in column. After the folding rod 4 is rotated to a suitable angle, the polygonal plug-in column can be inserted to limit the folding rod 4, so that the bottom end shaft 304 of the folding rod 4 is limited by the docking block 305. The folding part is limited by the polygonal plug-in column, which can prevent the folding rod 4 from shaking or bending.

[0053] In summary, the working principle of this scheme is as follows:

[0054] By opening and closing the base 1, the base 1 is placed on the ground and on the outer surface of the poplar seedling. At this time, the connecting plate 22 has been placed vertically by the rotating component 21. According to the height of the poplar seedling, the height of the connecting rod 3 is adjusted by the adjusting component 31. After adjusting to a suitable height, the rotating shaft 304 and the folding rod 4 are rotated to adjust the folding rod 4 to a suitable height, and then the clamping block 34 is pressed downward so that the clamping interface 302 at the bottom of the annular hinge sleeve 301 can be connected to the clamping block 34, and the extrusion spring 37 squeezes the clamping block 34 upward so that the annular hinge sleeve 301 can be connected to the anchoring block 34. The connecting sleeve 301 moves upward together, and then the docking block 305 on the top of the annular hinge sleeve 301 can be docked with the outer surface of the docking block 305, and the rotating shaft 304 is limited, so that the folding rod 4 is fixed at the same folding angle, and then another set of clamping components 36 can be installed on the spherical hinged connecting piece 42 of the folding rod 4, and another set of clamping components 36 can be installed through the plug-in block 6 on the top of the connecting piece 42, so that two sets of clamping components 36 in a vertical state can clamp the outer surface of the poplar seedling, and the poplar seedling can be prevented from bending by supporting at multiple points.
