Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit and vegetable pest control technology, specifically to a protective sleeve for preventing pests from crawling on the root collar of apple trees. Background Technology
[0002] Apple tree root collar protection sleeves are physical barriers that are usually installed at the root collar of apple trees (where the trunk meets the soil) to prevent pests from crawling from the ground to the trunk or canopy, thereby reducing the damage caused by pests to the trees.
[0003] In the prior art, such as Chinese Patent Application No. CN201720041243.9, a tree trunk protective sleeve is disclosed, including an outer protective sleeve and an inner protective sleeve. The inner protective sleeve is stacked on the outer protective sleeve, and the four sides of the outer protective sleeve are bent inward and cover the four corners of the inner protective sleeve. Several magnets are covered on the left and right sides of the outer protective sleeve. The magnets located on the left and right sides of the outer protective sleeve attract each other. The magnets are arranged sequentially at intervals along the sides of the outer protective sleeve, with an interval of no more than 10 cm. The outer protective sleeve has several longitudinal folds and can be stretched laterally. The inner protective sleeve includes, from the inside out, a phenolic foam layer, a coconut fiber layer, and a lightweight microporous rubber layer. The inner protective sleeve consists of two pieces, left and right, and a shrink band is sewn between the two pieces of the inner protective sleeve.
[0004] Based on the above information, it can be seen that the root collar protective sleeve in the existing technology achieves the purpose of protection by wrapping it around the outside of the tree trunk. However, when fruit trees are planted (such as apple trees), some sweet-loving pests will crawl from the ground to the trunk and damage the fruit. Utility Model Content
[0005] The purpose of this invention is to provide a protective sleeve for preventing pests from climbing the root collar of apple trees, overcoming the problem of the inability to prevent pests from climbing in the aforementioned background technology.
[0006] To achieve the above objectives, the technical approach adopted by this utility model is to design the outer surface of the protective cover as a smooth structure to prevent pests from climbing, and to achieve the purpose of repelling pests through insect repellent.
[0007] Based on the above technical concept, the technical solution adopted by this utility model is as follows:
[0008] A protective sleeve for preventing pests from crawling on the root collar of an apple tree, comprising a soft protective sleeve wrapped around the root collar of the apple tree; a hollow storage box is provided on the outside of the soft protective sleeve, and a water-retaining sponge containing liquid insect repellent is provided inside the storage box, and a disassembly and replacement mechanism is provided between the storage box and the soft protective sleeve.
[0009] Preferably, the disassembly and replacement mechanism includes mounting hooks fixedly installed at the upper and lower ends of the storage box, and through holes with equal spacing are opened on the outer surface of the storage box.
[0010] Preferably, the mounting hook and the mounting ring are engaged and fixed together, and the mounting ring is made of silicone and is fixedly installed on the outer surface of the soft protective cover at equal intervals.
[0011] Preferably, a first Velcro strap and a second Velcro strap are fixedly installed at the edges of the inner and outer sides of the soft protective case, respectively, and the first Velcro strap and the second Velcro strap are glued and fixed together.
[0012] Preferably, a horizontally arranged inner lining strip is fixedly installed on the inner surface of the soft protective sleeve, and the inner lining strip has equally spaced clearance grooves inside.
[0013] Preferably, the soft protective case consists of three parts: a mesh layer, a silicone layer, and a smooth layer.
[0014] Preferably, the mesh layer is a nylon mesh woven structure, the silicone layer is made of soft silicone, and the smooth layer is made of aluminum foil.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] (1) Wrap the soft protective sleeve around the root collar of the apple tree, and then use the adhesive action between the first and second Velcro to fix the soft protective sleeve. The outermost layer of the soft protective sleeve is a smooth layer of aluminum foil to prevent pests from climbing up to the trunk (the smoothness reduces friction so that pests have no point of leverage when climbing).
[0017] (2) A storage box is set on the outside of the soft protective cover. A water-retaining sponge is placed inside the storage box. Liquid insect repellent is injected into the water-retaining sponge. The water-retaining sponge stores the insect repellent by storing water. The insect repellent evaporates and is slowly released to achieve the purpose of repelling pests. Installation hooks are set at the top and bottom of the storage box. The disassembly and installation structure between the installation hooks and the installation rings allows the storage box to be replaced.
[0018] (3) An inner lining strip is fixedly installed on the inner surface of the soft protective sleeve. The inner lining strip is made of soft aluminum alloy. The metal can improve the shaping ability of the soft protective sleeve. Furthermore, an avoidance groove is opened in the inner lining strip. The avoidance groove can ensure the bending ability of the inner lining strip. Attached Figure Description

The storage box 6 is provided with a water-retaining sponge 8 that absorbs liquid insect repellent. The storage box 6 and the soft protective cover 1 are provided with a disassembly and replacement mechanism. The disassembly and replacement mechanism includes mounting hooks 9 fixedly installed at the upper and lower ends of the storage box 6. The outer surface of the storage box 6 has through holes 7 that are evenly distributed. The mounting hooks 9 are engaged and fixed with mounting rings 10. The mounting rings 10 are made of silicone and are fixedly installed on the outer surface of the soft protective cover 1 at equal intervals.
[0033] According to the actual use, install the corresponding number of storage boxes 6 onto the outside of the soft protective cover 1 (the mounting hooks 9 at the top and bottom of the storage box 6 engage and fix with the mounting rings 10 on the outer surface of the soft protective cover 1 to install the storage box 6, and then remove and replace the storage box 6 through the mounting hooks 9). The storage box 6 is equipped with a water-retaining sponge 8 (the water-retaining sponge 8 stores liquid insect repellent in advance). During use, the liquid insect repellent in the water-retaining sponge 8 evaporates and is slowly released. The released insect repellent is dispersed through the through hole 7 opened on the outside of the storage box 6 to achieve the purpose of repelling insects.
