A biodegradable tree root ring-applied nutrient infusion device

Abstract

This invention provides a biodegradable tree root ring-applied nutrient infusion device, comprising multiple nutrient solution input modules and a locking assembly. The multiple nutrient solution input modules are evenly arranged in a circular pattern, and the locking assembly is connected to the multiple nutrient solution input modules. Each nutrient solution input module includes a controlled-release membrane layer, a reservoir layer, and an outer layer arranged sequentially from the inside out. The reservoir layer stores tree nutrient solution, and the controlled-release membrane layer is uniformly provided with micropores. The tree nutrient solution located in the reservoir layer seeps into the tree through the micropores. The multiple ring-arranged nutrient solution input modules are fixed around the tree trunk by the locking assembly, which can uniformly supply nutrient solution to the tree trunk. Because the reservoir layer in the nutrient solution input module stores tree nutrient solution, and the controlled-release membrane layer is uniformly provided with micropores, the tree nutrient solution in the reservoir layer seeps into the tree trunk through the micropores for absorption and use. Therefore, nutrient delivery to the tree trunk can be achieved in a non-invasive manner.

Description

Technical Field

[0001] This utility model relates to the field of tree maintenance technology, specifically to a biodegradable tree root ring-applied nutrient infusion device. Background Technology

[0002] For newly transplanted large trees, trees growing in harsh environments, or trees that have suffered stress from pests, diseases, or mechanical damage, their ability to absorb and transport nutrients from the soil is severely impaired, requiring external methods to administer nutrient solutions. A common external method is the tree nutrient infusion device, which directly delivers nutrient solution (containing water, minerals, and growth hormones) into the trunk, bypassing the damaged root system and directly replenishing the tree with the substances it needs to survive, thus improving its survival rate.

[0003] In existing technologies, the structure of a nutrient infusion device consists of a plastic infusion bag and a metal needle. By inserting the metal needle into the tree trunk, the nutrient solution in the plastic infusion bag flows into the trunk through the metal needle. Although this method can deliver the nutrient solution into the tree trunk, it causes permanent damage to the trunk (the hole diameter is generally 3-5 mm) because the metal needle is inserted into the trunk. Furthermore, the plastic infusion bag is difficult to degrade and can easily cause environmental damage. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a biodegradable tree root ring-applied nutrient infusion device, which aims to solve the problem that the existing tree nutrient infusion devices will cause damage to the tree trunk during use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This application provides a biodegradable tree root ring-applied nutrient infusion device, including multiple nutrient solution input modules and a locking assembly. The multiple nutrient solution input modules are evenly arranged in a circular pattern. The locking assembly is connected to the multiple nutrient solution input modules and is used to fix the multiple nutrient solution input modules to the tree in a circular pattern. Each nutrient solution input module includes a controlled-release membrane layer, a liquid storage layer, and an outer layer arranged sequentially from the inside out. The liquid storage layer stores tree nutrient solution. The controlled-release membrane layer is uniformly provided with micropores, and the tree nutrient solution located in the liquid storage layer seeps into the tree through the micropores.

[0006] Furthermore, an injection hole is provided on the upper surface of the liquid storage layer, and a cap can be detachably installed on the injection hole.

[0007] Furthermore, an adhesive layer is adhered to the inner wall of the controlled-release membrane layer.

[0008] Furthermore, the adhesive layer is a starch-based adhesive.

[0009] Furthermore, the outer layer comprises a polylactic acid layer and a wood fiber layer arranged sequentially from the inside out.

[0010] Furthermore, the controlled-release membrane layer is made of cellulose nanocomposite membrane.

[0011] Furthermore, the liquid storage layer is made of sodium alginate crosslinked gel.

[0012] Furthermore, the locking assembly includes a long strip-shaped belt, one end of which is provided with a plurality of through holes spaced apart along its length, and the other end of which is provided with a pin, and the outer sides of the plurality of nutrient solution input modules are slidably mounted on the belt.

[0013] Furthermore, a connecting block is fixed to the outer surface of the outer layer, and the connecting block has an insertion hole, in which the belt is slidably installed.

[0014] The beneficial effects of this utility model are as follows: multiple nutrient solution input modules arranged in a ring are fixed around the trunk by locking components, which can uniformly supply nutrient solution to the trunk. Since the nutrient solution input module stores tree nutrient solution in the liquid storage layer and the controlled release membrane layer is uniformly provided with micropores, the tree nutrient solution in the liquid storage layer seeps into the trunk through the micropores for the trunk to absorb and use. Therefore, the nutrient delivery of the trunk can be achieved in a non-invasive manner. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] See Figures 1 to 2 As shown, this embodiment provides a biodegradable tree root ring-applied nutrient infusion device 100, including multiple nutrient solution input modules 10 and a locking assembly 20. The multiple nutrient solution input modules 10 are evenly arranged in a circular pattern. The locking assembly 20 is connected to the multiple nutrient solution input modules 10 and is used to fix the multiple nutrient solution input modules 10 in a circular pattern to the tree. The nutrient solution input module 10 includes a controlled-release membrane layer 101, a liquid storage layer 102 and an outer layer 103 arranged sequentially from the inside to the outside. The liquid storage layer 102 stores tree nutrient solution. The controlled-release membrane layer 101 is uniformly provided with micropores. The tree nutrient solution located in the liquid storage layer 102 seeps into the tree through the micropores. The diameter of the micropores is 0.2 micrometers to respond to changes in soil moisture.

[0022] When nutrient solution is introduced into the tree, multiple nutrient solution input modules 10 are fixedly arranged in a ring around the trunk by locking components 20 to uniformly supply nutrient solution to the trunk. Since the nutrient solution input module 10 stores tree nutrient solution in the liquid storage layer 102, and the controlled release membrane layer 101 is uniformly provided with micropores, the tree nutrient solution in the liquid storage layer 102 seeps into the trunk through the micropores for the trunk to absorb and use. Since the nutrient solution flows to the outer surface of the trunk in a permeable manner, the trunk absorbs the nutrient solution accumulated on its outer surface, achieving nutrient delivery to the trunk in a non-invasive manner.

[0023] In some embodiments, in order to accommodate tree trunks with different outer diameters, the diameter of the ring formed by the multiple nutrient solution input modules 10 is adjustable. That is, the diameter of the ring formed by the multiple nutrient solution input modules 10 can be adjusted by adjusting the locking length of the locking component 20.

[0024] Reference Figure 1 and Figure 4 As shown, in this embodiment, the locking assembly 20 includes a long strip-shaped belt 21. One end of the belt 21 has multiple through holes 22 spaced apart along its length, and the other end of the belt 21 has a pin 23. Multiple nutrient solution input modules 10 are slidably mounted on the outer side of the belt 21. It can be understood that the working principle of the belt 21 in this embodiment is the same as that of a commonly used leather belt 21. The diameter of the ring formed by the belt 21 is adjusted by the locking engagement of the pin 23 with the corresponding through holes 22 on the belt 21. The structure of the belt 21 is simple and easy for users to operate.

[0025] Reference Figure 2 and Figure 3 As shown, in this embodiment, a connecting block 30 is fixed to the outer surface of the outer layer 103. The connecting block 30 has an insertion hole 31. The waist belt 21 is slidably installed in the insertion hole 31. That is, the nutrient solution input module 10 is installed on the waist belt 21 through the insertion hole 31 on the connecting block 30 on its outer surface. When the diameter of the ring formed by the waist belt 21 is adjusted, the distance between two adjacent nutrient solution input modules 10 is adjusted by moving the size of the distance between them. When the diameter of the ring formed by the waist belt 21 is adjusted to be smaller, the distance between two adjacent nutrient solution input modules 10 is shortened; conversely, when the diameter of the ring formed by the waist belt 21 is adjusted to be larger, the distance between two adjacent nutrient solution input modules 10 is increased.

[0026] Reference Figure 3 As shown, in this embodiment, to facilitate the addition of nutrient solution into the liquid storage layer 102, an injection hole is provided on the upper surface of the liquid storage layer 102. The injection hole is connected to the inner cavity of the liquid storage layer 102, and a cap is detachably installed on the injection hole. When injecting nutrient solution, the cap is loosened, and the nutrient solution is injected into the liquid storage layer 102 through the injection hole, which is simple and convenient.

[0027] In some embodiments, an adhesive layer is adhered to the inner wall of the controlled-release membrane layer 101. This adhesive layer is used to bond the controlled-release membrane layer 101 to the outer surface of the tree trunk, reinforcing the adhesion and fixation of the nutrient solution input module 10 to the outer surface of the tree trunk. It is understood that the adhesive layer has a small width, meaning it only partially adheres to the inner wall of the controlled-release membrane layer 101, thus not affecting the penetration of the nutrient solution through the controlled-release membrane layer 101 to the outer surface of the tree trunk. In other embodiments, the adhesive layer is a starch-based adhesive. The selection of a starch-based adhesive allows it to be activated upon contact with water, facilitating removal from the tree trunk without damaging its outer surface.

[0028] In some embodiments, the outer layer 103 comprises a polylactic acid layer and a wood fiber layer disposed sequentially from the inside out. The controlled-release membrane layer 101 is made of a cellulose nanocomposite membrane, and the liquid storage layer 102 is made of sodium alginate crosslinked gel.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
