Description

Technical Field

[0001] The utility model relates to the technical field of ancient trees, in particular to a back-pressure ancient tree rejuvenation pipe. Background Art

[0002] Ancient and famous trees are witnesses of a city’s history and have important cultural and scientific value. Therefore, when ancient trees reach old age and their growth enters a slow, aging stage, human intervention is needed to rejuvenate them.

[0003] When the growth of ancient trees weakens, one of the main reasons is that the growth environment of the ancient tree roots has undergone adverse changes, mainly in terms of water, gas, nutrients, etc. Because the soil is compacted and the growth space is too small, it is difficult for water to infiltrate and for gas exchange in the soil to occur. This is specifically manifested in the weakened growth of some ancient trees, with smaller and yellower leaves in normal seasons.

[0004] Judging from the results of the ancient tree resource surveys currently launched in various places, the number and quality of ancient trees and famous trees in my country have declined significantly, and the rescue of ancient trees is imminent. The existing rejuvenation work for the root system of ancient trees is to drill holes with a steel drill, pour in perlite and slow-release fertilizers, and water with strong rooting liquid to improve soil permeability and increase fertility. However, the air in the holes drilled by the steel drill cannot flow with the outside air, resulting in the gas formed after deep root lesions entering the hole, reducing the efficiency of root gas exchange, and the rejuvenation effect is not obvious. Therefore, those skilled in the art are in urgent need of a device that can effectively improve the permeability of the root system of ancient trees.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present application, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0006] The utility model aims to provide a back-pressure ancient tree rejuvenation pipe to solve the technical problems existing in the prior art.

[0007] In order to solve the above technical problems, the utility model provides a counter-pressure ancient tree rejuvenation tube, which comprises an outer sleeve and an inner sleeve, wherein the upper and lower ends of the outer sleeve and the inner sleeve are open, the inner sleeve is a reducer with a lower inner diameter smaller than an upper inner diameter, and a side hole is provided on the upper wall of the outer sleeve, and the upper end of the inner sleeve extends out of the outer sleeve through the side hole.

[0008] Furthermore, the outer sleeve is divided into two parts, the upper part of the outer sleeve is the tube head, and the lower part of the outer sleeve is the breathable cloth tube. A hoop is provided at the upper end of the breathable cloth tube, and the hoop is inserted into the tube head. An adjusting clamp is provided on the outside of the tube head, and the adjusting clamp is fastened to the lower side of the hoop. The adjusting clamp squeezes the tube head inward to reduce the inner diameter of the tube head, so that the inner wall of the compressed tube head is blocked on the falling channel of the hoop, thereby connecting the tube head with the breathable cloth tube.

[0009] Furthermore, a detachable upper cover is provided at the upper end of the outer sleeve, and a shutter is provided on the upper cover.

[0010] Furthermore, the inner sleeve includes: a thin tube, a thick tube and a bent tube, the thin tube and the thick tube are connected by a reducer, a threaded elbow is provided at the upper end of the thick tube, the bent tube passes through the side hole and is connected to the threaded elbow, and the opening direction of the bent tube can be changed by rotating the bent tube.

[0011] Furthermore, when the counter-pressure ancient tree rejuvenation pipe is buried underground, the upper part of the outer sleeve is placed on the ground.

[0012] By adopting the above technical solution, the utility model has the following beneficial effects:

[0013] The counter-pressure ancient tree rejuvenation pipe provided by the utility model can reduce the air pressure acting on the pipe. The faster the speed of the gas, the smaller the pressure acting on the fluid contact interface will be, and the faster the air flows, the smaller the pressure on the contact interface between the object and the fluid will be. The surface airflow enters the ground through the inner casing, and the gas formed by the root lesions in the outer casing is pressed out from the top, thereby improving the efficiency of root gas exchange. The variable diameter inner casing can speed up the airflow velocity entering the bottom of the outer casing, thereby increasing the thrust of the gas formed by the upward root lesions.

[0014] The breathable fabric tube is made of geotextile. The air entering the outer tube from the inner tube can penetrate the breathable fabric tube, increasing the exchange range between air and the root system. At the same time, the air formed after the root disease can also enter the outer tube through the breathable fabric tube, effectively improving the air in the deep soil.

[0015] The upper cover on the upper end of the outer sleeve can prevent impurities from falling and does not affect the inflow and outflow of gas.

[0016] The bend of the inner sleeve can rotate in direction. When the bend is horizontal, it is convenient for external airflow to enter the outer sleeve for gas exchange; when the bend is downward, it can effectively reduce the airflow entering, making it convenient for operators to control.

[0027] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0028] like Figure 1 and Figure 2 The figure shows a specific embodiment of the counter-pressure ancient tree rejuvenation tube of the utility model. In this embodiment, the counter-pressure ancient tree rejuvenation tube specifically comprises: an outer sleeve 1 and an inner sleeve 2. The upper and lower ends of the outer sleeve 1 and the inner sleeve 2 are open without end walls.

[0029] The outer sleeve 1 is composed of two parts, the upper part of the outer sleeve 1 is the pipe head 11, and the lower part of the outer sleeve 1 is the breathable cloth tube 12, which is specifically made of a polypropylene mesh tube and a geotextile. A hoop 13 is provided at the upper end of the breathable cloth tube 12, and the hoop 13 is a stainless steel hoop. The hoop 13 is inserted into the pipe head 11, and an adjustment clamp 17 is provided on the outer side of the pipe head 11. The adjustment clamp 17 is fastened below the hoop 13. The pipe head 11 is squeezed inward by the adjustment clamp 17, so that the pipe head 11 is deformed, the inner diameter of the pipe head 11 is reduced, and the inner wall of the compressed pipe head 11 is blocked on the falling channel of the hoop 13, so that the hoop 13 is clamped in the pipe head 11, thereby connecting the pipe head 11 with the breathable cloth tube 12.

[0030] A side hole 16 is provided on the side wall of the pipe head 11 , and a detachable upper cover 14 is provided on the upper end of the pipe head 11 , on which a shutter 15 is provided.

[0031] The inner sleeve 2 specifically includes: a thin tube 21, a thick tube 23 and a bent tube 25. The thin tube 21 is arranged below the thick tube 23. The thin tube 21 and the thick tube 23 are connected by a reducer 22. A threaded elbow 24 is arranged at the upper end of the thick tube 23. The bent tube 25 passes through the side hole 16 of the pipe head 11 and is connected to the threaded elbow 24. The opening direction of the bent tube 25 can be changed by rotating the bent tube 25.

[0032] When the counter-pressure ancient tree rejuvenation pipe is buried underground, the upper part of the pipe head 11 is placed on the ground, and the height should be guaranteed so that the bent pipe 25 will not interfere with the ground when rotating.

[0033] In the counter-pressure ancient tree rejuvenation tube of this embodiment, the bend 25 of the inner sleeve 2 can rotate. When the bend 25 opens horizontally, it is convenient for the outside airflow to enter the outer sleeve for gas exchange. The outside airflow enters the underground through the inner sleeve 2, and the gas formed after the root lesions in the outer sleeve 1 are pressed out from the top, thereby improving the efficiency of root gas exchange. The variable diameter inner sleeve 2 can speed up the airflow velocity entering the bottom of the outer sleeve 1, thereby increasing the thrust of the gas formed after the upward root lesions. When the bend 25 opens downward, it can effectively reduce the airflow entering, which is convenient for the operator to control.

[0034] The breathable cloth tube 12 is specifically made of geotextile, and the air entering the outer tube 1 from the inner tube 2 can penetrate the breathable cloth tube 12, increasing the exchange range between air and the root system. At the same time, the air formed after the root disease can also enter the outer tube 1 through the breathable cloth tube 12, so that the air in the deep soil is effectively improved.

[0035] The upper cover 14 at the upper end of the outer sleeve 1 can prevent impurities from falling and does not affect the inflow and outflow of gas.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
