Description

Technical Field

[0001] The invention relates to the technical field of forest management, and in particular to a tree transplanting soil ball packaging bag. Background Art

[0002] In forest management, tree transplantation, as an important technical means of replanting and rebuilding forest ecosystems, can quickly and efficiently restore forest functions and structures. Through reasonable planning and scientific implementation, tree transplantation can help the sustainable management of forest resources and provide strong support for ecological protection and economic development.

[0003] Soil ball wrapping is to wrap the soil ball around the roots of trees during tree transplantation to prevent tree root death and improve tree survival rate. The existing publication number CN109169141B discloses a patent for a tree transplantation soil ball packaging bag.

[0004] In the prior art, there are a variety of ways to wrap the soil ball when transplanting trees. One method is to wrap the soil ball in a winding manner, and the other method is to wrap the soil ball at the root of the tree with a soil ball wrapping cloth. When the soil ball is wrapped using the above two methods, once the soil ball is subjected to external collision and compression during transportation, it is very easy to cause the soil ball where the plant roots gather to fall off or even break, thereby affecting the survival rate of subsequent tree transplantation. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a tree transplanting soil ball packaging bag, which solves the technical problem that the soil ball is easily knocked or squeezed by the outside during transportation, which may cause the soil ball where the plant roots gather to fall off or even break.

[0007] (II) Technical solution

[0008] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0009] An embodiment of the present invention provides a tree transplanting soil ball packaging bag, including a bag body directly covering the soil ball and a partition bag box for inserting the soil ball and the bag body, the bag body including an inner layer directly in contact with the soil ball and covering the soil ball, an airbag expansion layer arranged on the outer surface of the inner layer, and an outer layer arranged on the outer surface of the airbag expansion layer, the airbag expansion layer expands under external inflation and increases the distance between the inner layer and the outer layer, the partition bag box includes an external box body and a wrapping cotton layer arranged inside the box body, the wrapping cotton layer and the inside of the box body form a partition cavity for inserting the soil ball and the bag body.

[0010] A tree transplanting soil ball packaging bag proposed in an embodiment of the present invention, when the tree transplanting soil ball is packaged by the packaging bag, the bag body is directly covered on the surface of the soil ball so that the inner covering layer is in direct contact with the soil ball, and then the airbag expansion layer is inflated so that the airbag expansion layer completely separates the inner covering layer and the outer covering layer, and finally the soil ball wrapped with the bag body is directly placed in the separation cavity of the separation bag box. At this time, the wrapping cotton layer in the separation cavity will support the bag body, so that when external extrusion and collision occur, the wrapping cotton layer and the inflated airbag expansion layer can effectively isolate the extrusion and collision, thereby reducing the chance of the soil ball falling off or even breaking.

[0011] Optionally, the inner envelope and the outer envelope are provided with air holes in a uniform array, and the airbag expansion layer is in a grid shape.

[0012] Since trees are always alive during the transplantation process, once the soil ball is completely airtightly wrapped, it is easy to cause large-scale death of the roots of the trees wrapped by the soil ball. In this solution, air holes are opened on both the inner and outer layers, and the airbag expansion layer is set to a grid shape. While providing sufficient protection, the roots inside the soil ball can exchange air with the outside, thereby improving the survival rate of tree transplantation.

[0013] Optionally, the inner and outer layers are bonded at the edges and extend outward to form four wide strips that do not interfere with each other. When the bag body is laid flat, the angle between adjacent wide strips is 90 degrees. The edges of the wide strips away from the center of the bag body are inserted with load-bearing rods along their own width direction. The top of the box body is horizontally provided with four insertion and fixing grooves on the periphery of the partition cavity for the load-bearing rods to be inserted and fixed respectively. Driven by the load-bearing rods, the wide strips are bent and reversed to the side adjacent to the wide strip to cover the soil ball.

[0014] By means of the load-bearing rods inserted on the four wide strips, the entire tree can be lifted and lowered by the load-bearing rods, so that when the entire tree is lifted, the pressure on the soil ball is more balanced to reduce the chance of falling debris. At the same time, when transporting the tree, the load-bearing rods can drive the wide strips to bend and flip to the side of the adjacent wide strips and fix them in the insertion and fixing grooves on the top of the box body. On the one hand, the entire soil ball is fixed by fixing the four load-bearing rods. On the other hand, the four wide strips are bent and flipped to cover the top of the soil ball, thereby improving the covering effect.

[0015] Optionally, the wide strip is inserted into the end of the load-bearing rod to integrally form a load-bearing insertion hole for the load-bearing rod to be inserted into.

[0016] By integrally connecting the edges of the inner and outer layers and forming a load-bearing socket for inserting the load-bearing rod at the integrally connected position, on the one hand, the installation of the load-bearing rod is more convenient and quick; on the other hand, when the entire tree is lifted by the load-bearing rod, the force can be more evenly dispersed on the wide strip, which is safer.

[0017] Optionally, the box body is provided with two rotating seats that rotate synchronously and parallely in the insertion and fixing groove, a winding rod eccentric to the rotation axis of the rotating seat is vertically connected between the two rotating seats, the load-bearing insertion rod is parallel to the winding rod and is detachably fixed between the two rotating seats, the load-bearing insertion rod is eccentric to the rotation axis of the rotating seat, and the wide strip is wound around the outer surfaces of the winding rod and the load-bearing insertion rod and tightened under the rotation of the rotating seat.

[0018] By rotatably setting two rotating seats in the insertion and fixing grooves of the box body, the two rotating seats can drive the winding rod to rotate, and the load-bearing plug rod is detachably connected between the two rotating seats. At the same time, the load-bearing plug rod is eccentric to the rotation axis of the rotating seat and parallel to the winding rod, so that when the rotating seat drives the load-bearing plug rod and the winding rod to rotate together, the loose wide strip will be wound around the winding rod and the load-bearing plug rod, so that the wide strip is gradually tightened, thereby tightening and covering the top of the soil ball, and at the same time, the gravity of the soil ball can be borne by the entire bag body.

[0019] Optionally, one end surface of the rotating seats in the same group that is close to each other is provided with a positioning slot for inserting the end of the load-bearing plug rod at the edge away from the winding rod and toward the center.

[0020] Positioning slots are provided at the edges of the two rotating seats close to one end surface, so that the load-bearing plug rods can be installed on the rotating seats more conveniently.

[0021] Optionally, the box body is buckled with a box cover at the opening of the partition cavity, and the box cover includes two half covers and a sliding cover slidably connected to one end surface of the half cover, the two half covers are connected to the top of the box body at ends away from each other, and the two sliding covers are abutted at ends close to each other and are provided with a groove for trees to pass through.

[0022] When the bag wrapped with the soil ball is completely inserted into the partition cavity, the box cover is closed. At this time, the half cover is installed on the top of the box body, so that the two sliding covers slide toward each other until the two sliding covers stop after their side ends close to each other touch the surface of the tree. At this time, the tree is inserted into the groove, thereby protecting the top of the soil ball and reducing the risk of the soil ball falling off or even breaking during transportation.

[0023] Optionally, one side end of the two halves of the half-cover that are away from each other is rotatably connected to the top of the box body, and a "T"-shaped groove is provided on the upper end surface of the half-cover, and a slider is provided on the lower end surface of the sliding cover, which is embedded in the "T"-shaped groove and slides along the length direction of the "T"-shaped groove. A tension spring is fixed in the "T"-shaped groove of the half-cover, and one end of the tension spring is fixed to the slider. The tension spring pulls the two sliding covers to slide toward each other.

[0024] The half cover is connected to the top of the box body by rotation, and the sliding cover is connected to the half cover by sliding through a "T"-shaped sliding groove and a slider, so that the two sliding covers are always in a state of abutting each other under the drive of the tension spring. When the box cover needs to be buckled, it only needs to be rotated until the two half covers abut against the upper end of the box body. During the rotation, the groove on the sliding cover buckles the side end of the tree, and as the rotation continues, the sliding cover slides relative to the half cover and stretches the tension spring until the cover is completely buckled. This solution makes the closing process of the box cover more convenient.

[0025] Optionally, a universal pulley is provided at the bottom of the box body.

[0026] By arranging a universal pulley at the bottom of the box body, the box body can be moved under the drive of the universal pulley, thereby facilitating the movement of the entire separation bag box to facilitate the subsequent transplantation of trees.

[0027] Optionally, the inner cladding layer and the outer cladding layer both include two layers of transparent films and a fiber mesh layer bonded between the two layers of transparent films, and the airbag expansion layer is transparent.

[0028] By arranging two layers of transparent films for the inner and outer layers and bonding a fiber mesh layer between the two layers of transparent films, the structural strength of the inner and outer layers is increased and the tensile strength is stronger, so that the entire packaging bag can be reused and is more economical. In addition, the airbag expansion layer is set to be transparent, so that the operator can view the status of the soil ball in real time when packaging the soil ball through the bag body, thereby facilitating operations during loading and unloading, which is more convenient.

[0029] (III) Beneficial effects

[0030] The beneficial effects of the present invention are as follows: when the tree transplanting soil ball packaging bag of the present invention is used to package the tree transplanting soil ball, the bag body is directly covered on the surface of the soil ball so that the inner covering layer is directly in contact with the soil ball, and then the airbag expansion layer is inflated so that the airbag expansion layer completely separates the inner covering layer and the outer covering layer, and finally the soil ball covered with the bag body is directly placed in the separation cavity of the separation bag box, at this time, the wrapping cotton layer in the separation cavity will support the bag body, and then when external extrusion and collision occur, the wrapping cotton layer and the inflated airbag expansion layer can effectively isolate the extrusion and collision, thereby reducing the probability of the soil ball falling off or even breaking.

DETAILED DESCRIPTION

[0037] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0038] The tree transplanting soil ball packaging bag proposed in the embodiment of the present invention, when the tree transplanting soil ball is packaged by means of the packaging bag, the bag body is directly wrapped on the surface of the soil ball so that the inner wrapping layer is in direct contact with the soil ball, and then the airbag expansion layer is inflated so that the airbag expansion layer completely separates the inner wrapping layer and the outer wrapping layer, and finally the soil ball wrapped with the bag body is directly placed into the separation cavity of the separation bag box. At this time, the wrapping cotton layer in the separation cavity will support the bag body, so that when there is external extrusion and collision, the wrapping cotton layer and the inflated airbag expansion layer can effectively isolate the extrusion and collision, thereby reducing the chance of the soil ball falling off or even breaking.

[0039] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0040] Reference Figures 1 to 4A tree transplant soil ball packaging bag includes a bag body 1 directly covering the soil ball and a separation bag box 2 for inserting the soil ball and the bag body 1.

[0041] The bag body 1 includes an inner layer 11 that is in direct contact with and covers the soil ball, an airbag expansion layer 13 disposed on the outer surface of the inner layer 11, and an outer layer 12 disposed on the outer surface of the airbag expansion layer 13. The airbag expansion layer 13 expands under external inflation and increases the distance between the inner layer 11 and the outer layer 12. When the soil ball for tree transplantation is packaged by the packaging bag, the bag body 1 is directly wrapped on the surface of the soil ball so that the inner layer 11 is in direct contact with the soil ball, and then the airbag expansion layer 13 is inflated so that the airbag expansion layer 13 completely separates the inner layer 11 from the outer layer 12, so that when there is external extrusion and collision, the inflated airbag expansion layer 13 can effectively isolate the extrusion and collision, reducing the probability of the soil ball falling off or even breaking.

[0042] The inner and outer layers 11 and 12 are uniformly arrayed with air holes 111, and the airbag expansion layer 13 is in a grid shape, thereby providing adequate protection while allowing the roots inside the soil ball to exchange air with the outside, thereby increasing the survival rate of transplanted trees.

[0043] The inner layer 11 and the outer layer 12 are bonded at the edges and extend outward to form four wide strips 14 that do not interfere with each other. When the bag body 1 is laid flat, the angle between adjacent wide strips 14 is 90 degrees. The inner layer 11 and the outer layer 12 are integrally connected at the edge of the wide strip 14 away from the center of the bag body 1 to form a load-bearing plug hole 141. A load-bearing plug rod 142 is inserted into the load-bearing plug hole 141. On the one hand, the installation of the load-bearing plug rod 142 is more convenient and quick. On the other hand, when the entire tree is lifted by the load-bearing plug rod 142, the force can be more evenly dispersed on the wide strip 14, which is safer.

[0044] The inner layer 11 and the outer layer 12 both include two layers of transparent films 112 and a fiber mesh layer 113 bonded between the two layers of transparent films 112, and the airbag expansion layer 13 is transparent. This makes the inner layer 11 and the outer layer 12 have higher structural strength and stronger tensile strength, so that the entire packaging bag can be reused and is more economical. In addition, the airbag expansion layer 13 is set to be transparent, so that the operator can watch the state of the soil ball in real time when packaging the soil ball through the bag body 1, thereby facilitating the operation during loading and unloading, which is more convenient.

[0045] The separation bag box 2 includes an outer box body 21 and a wrapping cotton layer 22 disposed inside the box body 21. The wrapping cotton layer 22 and the box body 21 form a separation cavity 23 for inserting the soil ball and the bag body 1. The soil ball wrapped with the bag body 1 is directly placed into the separation cavity 23 of the separation bag box 2. At this time, the wrapping cotton layer 22 in the separation cavity 23 will support the bag body 1, so that when there is external extrusion and collision, the wrapping cotton layer 22 can effectively isolate the extrusion and collision, reducing the probability of the soil ball falling off or even breaking.

[0046] Four insertion and fixing grooves 211 for the load-bearing rods 142 to be inserted and fixed are horizontally opened on the top of the box body 21 on the side of the partition cavity 23. The wide strips 14 are bent and reversed to the side of the adjacent wide strips 14 under the drive of the load-bearing rods 142 to cover the top of the soil ball (not shown in the figure). On the one hand, the entire soil ball is fixed by fixing the four load-bearing rods 142. On the other hand, the four wide strips 14 are bent and reversed to cover the top of the soil ball to improve the covering effect. If the load-bearing rods 142 are directly inserted into the corresponding insertion and fixing grooves 211, a layer of wrapping cotton layer 22 can be laid on the top of the soil ball for protection.

[0047] The box body 21 is provided with two rotating seats 212 in the insertion and fixing groove 211, which are driven by a motor to rotate synchronously and parallelly. A winding rod 213 eccentric to the rotation axis of the rotating seat 212 is vertically connected between the two rotating seats 212. The load-bearing plug rod 142 is parallel to the winding rod 213 and is detachably fixed between the two rotating seats 212. The load-bearing plug rod 142 is eccentric to the rotation axis of the rotating seat 212. The wide strip 14 is wound around the outer surfaces of the winding rod 213 and the load-bearing plug rod 142 and tightened under the rotation of the rotating seat 212. The end faces of the rotating seats 212 in the same group that are close to each other are provided with a positioning slot 2121 for inserting the end of the load-bearing plug rod 142 at the edge away from the winding rod 213 toward the center.

[0048] When the rotating seat 212 drives the load-bearing rod 142 and the winding rod 213 to rotate together, the wide strip 14, which is loose at this time, will be wound around the winding rod 213 and the load-bearing rod 142, so that the wide strip 14 is gradually tightened, thereby tightening and wrapping the top of the soil ball, and at the same time, the gravity of the soil ball can be borne by the entire bag body 1 to reduce the probability of the soil ball being subjected to single-point force.

[0049] The box body 21 is buckled with a box cover 24 at the opening of the partition chamber 23. The box cover 24 includes two half covers 241 and a sliding cover 242 slidably connected to one end surface of the half cover 241. The two half covers 241 are connected to the top of the box body 21 at one end away from each other. The two ends of the sliding covers 242 that are close to each other are abutted and have a slot 243 for the tree to pass through. The side ends of the two half covers 241 that are away from each other are rotatably connected to the top of the box body 21 through a rotating shaft. The upper end surface of the half cover 241 is provided with a "T"-shaped slide groove 2411, and the lower end surface of the slide cover 242 is integrally provided with a slider 2421 embedded in the "T"-shaped slide groove 2411 and sliding along the length direction of the "T"-shaped slide groove 2411. The half cover 241 is fixed with a tension spring 2412 in the "T"-shaped slide groove 2411 by bolts, and one end of the tension spring 2412 is fixed to the slider 2421. The tension spring 2412 pulls the two slide covers 242 to slide toward each other. When the box cover 24 needs to be buckled, it only needs to be rotated until the two half covers 241 abut against the upper end of the box body 21. During the rotation process, the groove 243 on the slide cover 242 buckles on the side end of the tree, and as the rotation continues, the slide cover 242 slides relative to the half cover 241 and stretches the tension spring 2412 until the cover is completely buckled.

[0050] A universal pulley 214 is fixed to the bottom of the box body 21 near the corner by bolts, so that the box body 21 can move under the drive of the universal pulley 214, thereby facilitating the movement of the entire partition bag box 2 to facilitate the subsequent transplantation of trees.
