Description

Technical Field

[0001] The utility model relates to a ventilation device for the roots of roadside trees, belonging to the technical field of garden maintenance. Background Art

[0002] At present, the oxygen supply or nutrient input to street trees on the market is achieved by straight tubes. However, the use of straight tubes, on the one hand, is easy to be blocked by impurities such as leaves or soil. On the other hand, in heavy rain or snow weather, a large amount of rainwater or sleet will accumulate in the tubes, eventually causing the roots of street trees to be soaked in rainwater or sleet for a long time and cause rot, which further damages the roots of the trees and affects the trees' absorption of nutrients. The utilization rate is extremely low, and it cannot effectively improve the air permeability of the roots of the trees, reducing their survival rate.

[0003] Due to the simple design of the ventilation tube and the lack of protective measures, the problem of poor root permeability is common in urban greening. At the same time, the surface soil has low fertilization absorption efficiency, making it difficult for trees to fully absorb the nutrients they need, affecting their growth and health. Utility Model Content

[0004] The utility model provides a ventilation device for the roots of street trees, which aims to improve the existing straight tube by adding protective measures on the straight tube, on the one hand to prevent impurities from falling into the tube, and on the other hand to prevent rain and snow from entering the tube, which would cause the roots of the street trees to rot due to being soaked in rain and snow. Ultimately, the ventilation of the roots of the trees is improved, and there is no impurity congestion in the straight tube, and rain and snow are not easy to enter, so that the roots of the trees in contact with the straight tube can be transported with nutrient solution in time, thereby enhancing the tree's efficiency in absorbing nutrients, improving the production environment of the trees, and significantly improving the survival rate and health level of the trees.

[0005] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions:

[0006] A ventilation device for the roots of street trees, comprising a straight tube, wherein a hollow inner cavity is provided inside the straight tube, a grate with sieve holes is detachably installed in the hollow inner cavity, a rain skimmer cover is detachably installed at one end of the straight tube, an opening is provided on the side wall of the rain skimmer cover, and the opening, the sieve holes and the hollow inner cavity are all connected.

[0007] By adopting the above scheme, a straight tube is inserted beside a street tree, with one end of the straight tube close to the root of the street tree, a grate with sieve holes is installed on the straight tube, and then a rain-skimming cover is covered on the other end of the straight tube. By arranging the rain-skimming cover on the straight tube, impurities such as leaves, soil, and rain and snow cannot enter the straight tube in large quantities due to the obstruction of the rain-skimming cover. Secondly, impurities such as leaves, soil, and rain and snow can be secondary intercepted by the grate and cleaned in time, thereby ensuring that the hollow inner cavity of the straight tube is less blocked, so that the opening, sieve holes and hollow inner cavity form a ventilation and nutrient delivery channel for the roots of the street trees, so that the roots of the trees in contact with the straight tube can receive nutrient solution delivery in time, thereby enhancing the tree's nutrient absorption efficiency, improving the tree's production environment, and significantly improving the tree's survival rate and health level.

[0008] Preferably, a breathable net is provided on the side wall of the straight tube.

[0009] Furthermore, the air-permeable net is arranged in parallel along the height direction of the straight tube.

[0010] The above scheme is adopted to set up a breathable net, the purpose of which is to form multiple breathable and nutrient transport channels, namely, one channel directly ventilates and transports nutrients to the tree roots through the openings, sieve holes, hollow inner cavities and the ends of the straight tubes, and the other channels ventilate and transport nutrients to the roots of the street trees on the side walls of the straight tubes through the openings, sieve holes, hollow inner cavities and breathable nets, thereby enhancing the trees' nutrient absorption efficiency, improving the trees' production environment, and significantly improving the trees' survival rate and health level; in addition, it can also prevent debris from being thrown into the straight tube to pollute the soil.

[0011] Preferably, the rain skimmer cover is threadedly sleeved on the end of the straight tube.

[0012] Preferably, the end of the straight tube is provided with an external thread, and the rain skimmer cover is provided with an internal thread, and the internal thread is engaged with the external thread so that the rain skimmer cover is covered on the straight tube.

[0013] Preferably, the rain skimmer cover comprises a ring, a support column and an umbrella-shaped plate, and there are multiple support columns. The head and tail ends of each support column are respectively connected to the ring and the umbrella-shaped plate, and an opening is set between every two adjacent support columns; the internal thread is set on the inner wall of the ring.

[0014] By adopting the above scheme, impurities such as leaves, soil and rain and snow will fall through the wall of the umbrella-shaped plate when encountering the umbrella-shaped plate, and will not enter the straight tube; in addition, it is easy to disassemble, and only needs to loosen the rain-skimming cover on the straight tube, and take out or not take out the grate with sieve holes in the straight tube to clean the impurities or rain and snow on the grate.

[0015] Preferably, a lap plate is installed on the side wall of the hollow inner cavity, and the grate with sieve holes is overlapped in the hollow inner cavity through the lap plate.

[0016] Preferably, a lifting hole is provided in the middle of the grate with sieve holes.

[0017] By adopting the above scheme, the lifting hole can be held by hand to facilitate the removal or installation of the grate with sieve holes in the straight tube, so as to facilitate the maintenance personnel to remove debris when maintaining the street trees. It helps to ensure the normal use of the straight tube and promote the smooth flow of air in the tube. In addition, another ventilation and nutrient delivery channel is formed through the opening, lifting hole and hollow inner cavity.

[0018] Preferably, the straight tube is made of PVC.

[0019] The beneficial effects of the utility model are:

[0020] (1) The straight tube in the utility model is provided with a plurality of air holes around it, which greatly improves the air circulation efficiency, improves the root breathing environment, and promotes the healthy growth of trees;

[0021] (2) The inside of the straight tube is connected by a lap plate with a grate with sieve holes to effectively block impurities. It is also equipped with a lifting hole, which is convenient for maintenance personnel to hold the lifting hole and pick up the grate from the straight tube to clean up debris at any time and keep the air vent unobstructed.

[0022] (3) A rain cover is provided at one end of the straight tube to prevent rain and snow from entering the tube and submerging the roots of trees, causing the roots of trees to rot, thereby causing damage to the roots of trees. The rain cover is connected to the straight tube by a thread, which is convenient for installation and removal;

[0023] (4) The straight tube is made of low-cost, practical, and reusable PVC material, which is low in cost and has extremely low maintenance costs.

[0024] (5) The straight tube not only improves root ventilation, but also serves as a delivery platform for nutrient solution or fertilizer, thereby improving the root's absorption efficiency of nutrients. It is an ideal channel for later maintenance and topdressing. There are multiple ideal channels, namely, openings, sieve holes, hollow cavities and the ends of the straight tubes, or openings, sieve holes, hollow cavities and multiple air-permeable nets, or openings, lifting holes, hollow cavities and the ends of the straight tubes, or openings, lifting holes, hollow cavities and multiple air-permeable nets.
