Description

Technical Field

[0001] The invention relates to the technical field of forestry, and in particular to an auxiliary device for forestry seedling cultivation and transplanting. Background Art

[0002] Forestry is an important part of the national economy. In the relationship between humans and the biosphere, forestry is engaged in the cultivation, protection and utilization of forest resources through advanced science and technology and management methods, and gives full play to the multiple benefits of forests. It is the main goal of building an ecological state. Seedling transplanting is an important part of the forestry development process. Forestry often focuses on planting trees such as eucalyptus, poplar, ginkgo and fir. In the forestry planting process, it is usually necessary to transplant the cultivated seedlings to improve the growth quality of the seedlings by changing their living environment. The transplanted seedlings are relatively fragile and easy to fall over under external forces or extreme weather, resulting in a lower survival rate. Therefore, the transplanted seedlings need to be supported and supported. Auxiliary support devices are usually used to support the seedlings to ensure their normal growth after transplanting.

[0003] The existing support device has a simple structure and often uses multiple wooden stakes and cable ties to provide auxiliary support for seedlings. Usually, multiple wooden stakes are inserted into the ground at an angle, and the other ends are pressed against the waist of the seedlings. The cable ties bind the wooden stakes to the seedlings. Considering that the wooden stakes have poor structural stability, light texture and weak stability in extreme weather, some support devices currently use stable and hard metal connecting rods, bolts, screw locks and other structures. The connecting rods are pressed against the outer wall of the waist of the seedlings by rotating the screw bolts and locking them with the locks. Some connecting rods have a telescopic function, and the ends that extend obliquely toward the ground are deeply rooted in the ground to achieve support.

[0004] After the seedlings are transplanted, the growth rate and morphological changes of the seedlings put forward higher requirements on the supporting devices, especially for fast-growing tree species such as eucalyptus and fir, which grow faster and the outer diameter and height of the trunk will change significantly in a short period of time. However, traditional supporting devices are usually fixed with cable ties, bolts or ropes. Although they can provide a certain supporting force, as the seedlings grow, the fixed parts of these supporting devices are prone to restricting the thickening of the trunk due to excessive tightness, and even affecting the transportation of nutrients and water, resulting in poor growth of the seedlings. Therefore, manual inspection and loosening are required regularly to ensure that they do not cause excessive restraint on the seedlings. However, the number of seedlings transplanted in the forest farm is huge, and manual operation is not only time-consuming and labor-intensive, but also easy to cause some seedlings to be damaged due to negligence.

[0032] A specific embodiment of the present invention is described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0033] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solutions of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0034] refer to Figure 1 、 Figure 3 and Figure 5 The present invention provides an auxiliary device for forestry seedling transplanting, comprising two semi-ring seats 1 which can be horizontally spliced into a circular shape, such as Figure 10 As shown, a plurality of legs 2 are fixedly connected to the bottom of the semi-ring seat 1, and a plurality of avoidance grooves 11 are opened along the circumference of the inner ring of the semi-ring seat 1. The avoidance groove 11 vertically penetrates the semi-ring seat 1, and each avoidance groove 11 is connected with a support assembly 3 for automatically retracting as the outer diameter of the seedling increases. The support assembly 3 includes: abutments, sliding members, and multiple groups of limit members. The abutments include a beam 31 vertically arranged in the avoidance groove 11, abutments 32 respectively fixed to both ends of the beam 31 and extending horizontally toward one side of the inner ring, and a cross bar 33 fixed to the middle part of the beam 31 and extending horizontally toward one side of the outer ring. The abutment 32 is used to contact the waist of the seedling, and the lower end of the beam 31 is fixedly connected to a fitting through a vertical rod 34 to keep the abutment 32 and the cross bar 33 horizontal. The heavy body 35 and the semi-ring seat 1 are horizontally provided with a through hole 12 in the middle of the avoidance groove 11 for the cross bar 33 to pass through, and a horizontally extending slide groove 13 is provided on the side wall of the through hole 12. The sliding member includes a slider 36 placed in the slide groove 13 and a first spring 37 for resetting the sliding member. The middle side wall of the beam 31 is rotatably connected to the slider 36 through a hinge shaft. Multiple groups of limiters are evenly distributed along the axial direction of the cross bar 33. The limiters include multiple baffles 38 connected to the circumference of the cross bar 33 and inclined toward one side of the hole. The distance between the outermost ends of two opposite baffles 38 in the same group of limiters is smaller than the aperture of the through hole 12. When the cross bar 33 is horizontal, the baffle 38 close to the through hole 12 passes through the through hole 12 with the cross bar 33.

[0035] The support rods 32 and 31 are connected to each other to form a circle, so that the support rods 3 can be fixed to the ground to prevent the support rods 32 from being displaced by wind or external forces. The cam 33 is pressed against the support 12 and the support 13 is pressed against the support 12, so that the support 13 is lifted and the support 13 is tightened.

[0036] In summary, in this device, when the outer diameter of the seedling increases, the support rod 32 is squeezed by the trunk, pushing the cross bar 33 to move outward. Since the cross bar 33 is connected to the slide groove 13 through the slider 36, and the design of the baffle 38 allows the cross bar 33 to move freely in a horizontal state, the support assembly 3 can automatically adjust its position as the seedling grows to avoid excessive restraint on the trunk. When the seedling tilts due to wind or other external forces, the cross bar 33 will tilt accordingly, and the baffle 38 cannot pass through the through hole 12, thereby preventing the cross bar 33 from moving further. At this time, the support assembly 3 can provide additional supporting force to prevent the seedling from falling over, and under the action of the counterweight 35, it further has a reverse straightening effect on the seedling. This device is suitable for seedlings of different diameters and heights, especially for fast-growing tree species such as eucalyptus and fir. Its automatic adjustment function reduces the frequency of manual intervention and reduces the labor intensity of forest management.

[0037] Specifically, the compression force of the first spring 37 provided in this device is relatively small, and only serves to assist the slider 36 in resetting, which is not enough to affect the squeezing of the outer wall of the seedling trunk. The core design of this device is that it can automatically adjust the support force as the seedling grows, avoiding frequent manual intervention operations, and at the same time ensuring that the seedlings obtain sufficient support force during the growth process to prevent tilting or lodging due to extreme windy weather or other external forces.

[0038] Further, refer to Figure 3 and Figure 4 The distance between two horizontally adjacent blocking bars 38 is greater than the thickness of the semi-ring seat 1 corresponding to the through hole 12. The semi-ring seat 1 is provided with stepped grooves 14 on both sides of the through hole 12. The size of the stepped grooves 14 is greater than the inner diameter of the through hole 12, and the through hole 12 is in the shape of a thin-walled plate.

[0039] In the above embodiment, it can be ensured that when the first set of blocking bars 38 passes through the through hole 12, the subsequent adjacent second set of blocking bars 38 can still achieve blocking support or continue to achieve adaptive adjustment according to the growth of the seedlings.

[0040] Further, refer to Figure 11 and Figure 12 The cam 33 is provided with a plurality of through holes 332 for interlocking with the plurality of locking plates 331, and the plurality of locking plates 33 are provided with plurality of locking plates 332 for interlocking with the plurality of locking plates 331.

[0041] In the above embodiment, due to the different requirements for the slight tilt allowed for different tree species in forestry, the conditions for whether the crossbar 33 can pass through the through hole 12 are also different. For example, a very small part of the trunk waist portion itself has a slightly tilted angle. Therefore, in this embodiment, by setting the blocking bar 38 as a structure with adjustable inclination, the overall applicability of the device structure can be improved. In order to make it easier for the crossbar 33 to pass through the through hole 12, when the threaded rod 4 is rotated, the threaded rod 4 will drive the corresponding threaded sleeve 5 inside it to limit the position of the sliding bar 51. Horizontal displacement is achieved. Since each first connecting rod 52 is in an articulated relationship with the corresponding threaded sleeve 5, an angle change occurs, so that the angle of the baffle 38 hinged to the cross bar 33 is uniformly changed. When each baffle 38 converges and retracts, it is easier for the cross bar 33 to pass through the through hole 12 horizontally. Conversely, the conditions for the cross bar 33 to pass through the through hole 12 are more stringent. Of course, in actual application, the most basic guarantee is that when the cross bar 33 is in a horizontal state, the maximum outer diameter of each baffle 38 formed by adjacent rings is smaller than the inner diameter of the through hole 12.

[0042] Further, refer to Figure 7 The semi-ring seat 1 is located in the slide groove 13 and has a blind hole horizontally opened on the inner wall on the side away from the slider 36. A guide rod 6 is slidably connected in the blind hole. The other end of the guide rod 6 is fixedly connected to the slider 36. The first spring 37 is sleeved on the guide rod 6. One end of the first spring 37 is fixedly connected to the slider 36, and the other end abuts against the semi-ring seat 1.

[0043] In the above embodiment, considering that the first spring 37 may be offset during the compression process, affecting the normal implementation of the structure, a guide rod 6 is provided to guide the compression of the first spring 37, wherein the guide rod 6 can be hidden and slid into the blind hole as the slider 36 is displaced.

[0044] Further, refer to Figure 5 、 6 8. The outer ring of the semi-ring seat 1 is provided with a plurality of notches 15 along its circumference and corresponding to the positions of the cross bars 33. Each notch 15 is connected with an auxiliary support assembly 7 for auxiliary support of the seedlings. The auxiliary support assembly 7 includes: two second connecting rods 71, two third connecting rods 72, and two second springs 73. Figure 2 As shown, the first ends of the two second connecting rods 71 are hinged to the ends of the corresponding cross rods 33 passing through the through holes 12, and one end of the two third connecting rods 72 is hinged to the outer ring arc wall of the semi-ring seat 1 through the bracket, and the other ends of the two third connecting rods 72 are respectively extended obliquely toward the upper and lower sides of the seedling waist, and the second ends of the two second connecting rods 71 are respectively inclined toward one side of the two third connecting rods 72, and the second end of the second connecting rod 71 is hinged to the adjacent corresponding third connecting rod 72, and the two second springs 73 are respectively fixedly connected to the middle parts of the two second connecting rods 71, and the other end of the second spring 73 is fixedly connected to the semi-ring seat 1.

[0045] In the above embodiment, the purpose of the slot 15 is to provide an avoidance effect for the second connecting rod 71. At the same time, considering that the height of the seedlings will change when the diameter grows rapidly, of course the waist position of the seedlings initially supported will change. Therefore, the two third connecting rods 72 provided in this embodiment can provide auxiliary support to the seedlings at different longitudinal heights as they grow, ensuring their most basic support as much as possible, and avoiding the seedlings from falling over in extreme weather and causing the roots to be pulled out. The second connecting rod 71 provided is connected to the third connecting rod 72 and the cross bar 33 respectively, and the position of the upper and lower supports of the seedlings can be adaptively changed according to the growth of the seedlings. Specifically, when the diameter of the seedlings becomes thicker, the cross bar 33 will pass through the through hole 12, thereby laterally pushing the two second connecting rods 71 connected thereto to shift, and the two second connecting rods 71 can support the corresponding two third connecting rods 72 to stretch. At this time, the two third connecting rods The acute angle between 72 will gradually increase, and at this time, the auxiliary support for seedlings of different heights will be changed, especially the upper third connecting rod 72 will be further approaching the middle waist of the seedling after growth, thereby providing the most basic stable support for the seedling, wherein the second spring 73 provided can reset the second connecting rod 71 and synchronously maintain the inclination angle. At the same time, the auxiliary cross bar 33 has the beneficial effect of being in a horizontal state away from the end of the beam 31, so that the implementation of the entire structure will not be affected by external interference. In summary, in this embodiment, as the seedlings grow, the diameter and height all grow, the second connecting rod 71 and the third connecting rod 72 can be used to link the cross bar 33 to automatically and adaptively bundle the trunks and change the position of the auxiliary support seedlings, which satisfies the adaptive change of the bundling size and the adjustment of the support position after the seedlings grow, and also ensures the most basic and relatively stable auxiliary support for the seedlings in extremely windy weather.

[0046] Further, refer to Figure 8 The two push rods 32 are used to contact the upper and lower outer walls of the middle waist of the seedling respectively. The end of the push rod 32 away from the beam rod 31 contacts the outer wall of the seedling through the soft first roller 8, and the ends of the two third connecting rods 72 both contact the outer wall of the seedling through the soft second roller 9.

[0047] In the above embodiments, the first roller 8 and the second roller 9 are both provided to flexibly contact the outer surface of the stem of the seedling, thereby preventing the support rod 32 or the third connecting rod 72 from scratching or even scraping off the outer surface bark of the seedling after the seedling is tilted. At the same time, the first roller 8 and the second roller 9 can be used to better assist the seedling in resetting after tilting.

[0048] Further, refer to Figure 6 、 Figure 7 and Figure 8The beam rod 31 is fixedly connected to the positions near the two ends with third springs 10 . The two third springs 10 are arranged obliquely and the other ends are fixedly connected to the semi-ring seat 1 .

[0049] In the above embodiments, considering that seedlings are more likely to fall over in extremely windy weather, this embodiment, on the basis of setting a counterweight body 35, further uses two third springs 10 to assist in supporting the beam 31, which can achieve a faster reset effect without a large external force after the beam 31 tilts. At the same time, a third spring 10 is set, and the reaction elastic force of the third spring 10 can be used to assist the seedlings, and the reaction support of the tilted seedlings in extremely windy weather can be used, thereby preventing the roots of the seedlings from being pulled out and improving the survival rate of the seedlings in extreme weather.

[0050] Further, refer to Figure 9 The outer sides of the two axial sections of the semi-ring seat 1 are fixed with ear blocks 16, and the ear blocks 16 are transversely provided with through holes 161 for the bolts to pass through. The two semi-ring seats 1 are detachably connected by bolts.

[0051] In the above embodiment, each half ring seat 1 is welded with two ear blocks 16, and the outer side of the ear block 16 is arranged in a semi-arc shape. When in use, Figure 5 As shown, the end faces of the two half-ring seats 1 can be brought close together and spliced into a complete ring, and then two bolts are used to pass through the through holes 161 and locked with nuts. When the seedlings grow and no longer need auxiliary support, the disassembly is also relatively portable and will not increase the operating burden of the staff.

[0052] In summary, the core design of this device is to automatically adjust the support force as the seedlings grow, avoiding frequent manual intervention, while ensuring that the seedlings obtain sufficient support force during the growth process to prevent tilting or lodging due to extreme windy weather or other external forces.

[0053] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
