Description

Technical Field

[0001] This utility model belongs to the field of soil carbon and nitrogen emission detection technology, and relates to a simple manual installation device for a soil breathing ring. Background Technology

[0002] In agricultural, ecological, and environmental research fields, soil carbon and nitrogen emissions are often one of the main monitoring methods for studying soil greenhouse gas emissions and soil microbial activity. This requires researchers to conduct long-term, regular monitoring of the dynamic changes in soil carbon and nitrogen emissions. Using soil breathing rings is a common method for monitoring soil carbon and nitrogen emissions. Generally, two types of breathing rings are used: a 10cm ring to measure total respiration and a 40cm ring to measure heterotrophic respiration. However, soil breathing rings are easily damaged by sunlight and rain during long-term outdoor exposure. Furthermore, prolonged placement of breathing rings can lead to inaccuracies in soil carbon and nitrogen measurements, necessitating regular replacement to ensure the smooth conduct of experiments.

[0003] Current methods for placing soil breathing rings involve placing a metal or wooden board on the PVC breathing ring and then striking the board with a hammer to drive the ring into the soil, or directly striking the ring with a metal board. Both methods have several drawbacks, such as uneven stress on the ring causing damage to the ring's edges, and the ring tilting or even cracking during placement, all of which affect the accuracy of carbon and nitrogen emission monitoring. Utility Model Content

[0004] The purpose of this invention is to provide a simple manual installation device for a soil breathing ring, which is simple in structure, easy to operate, easy to carry in the field, can effectively protect the breathing ring, and has a good placement effect on the breathing ring.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows.

[0006] A simple manual installation device for a soil breathing ring includes a fixed base and a hand hammer. The fixed base comprises an inner cylinder and a placement cylinder integrally formed and coaxial from top to bottom. The outer diameter of the inner cylinder is smaller than the outer diameter of the placement cylinder, and the interior of the placement cylinder is used to place the soil breathing ring. The hand hammer includes a hammer cylinder and a handle mounted on the hammer cylinder. The hammer cylinder is movably fitted outside the inner cylinder of the fixed base. Both the fixed base and the hand hammer are made of solid iron plate. Utilizing the weight of the hand hammer, the hand hammer is manually lifted and lowered to apply a downward striking force to the placement cylinder of the fixed base, thereby hammering the soil breathing ring inside the placement cylinder into the soil. Simultaneously, because the breathing ring is placed inside the placement cylinder, it is effectively protected from direct hammering and prevented from being damaged. Furthermore, the force on the breathing ring is more evenly distributed, preventing the breathing ring from tilting during the hammering process.

[0007] Furthermore, this simplified manual installation device also includes positioning bolts; both the hammer cylinder and the inner cylinder have axially oriented slots on their walls, and the positioning bolts pass through these slots and are secured with nuts. By providing positioning bolts, a positioning guide is provided for the manual hammer's downward strike, ensuring that the manual hammer and the fixed base maintain a relatively fixed longitudinal position. This, in turn, ensures that the breathing ring experiences more even force and is less prone to tilting when it is being hammered.

[0008] Furthermore, the handle of this simplified manual installation device includes two U-shaped components symmetrically arranged on the side wall of the hammer cylinder. This handle structure allows for both horizontal and vertical grips, providing greater versatility in hand handling and enabling researchers to choose the appropriate method based on the specific situation during use.

[0009] Furthermore, in this simple manual installation device, the outer diameter of the hammer cylinder and the outer diameter of the placement cylinder are the same, both being 15cm to 30cm; the outer diameter of the inner cylinder is 1.5cm to 5cm smaller than the outer diameter of the placement cylinder.

[0010] Furthermore, in this simple manual installation device, the height of the hammer cylinder is 20cm to 40cm.

[0011] Furthermore, in this simple manual installation device, the wall thickness of the hammer cylinder is 1.5cm~2.5cm, the wall thickness of the inner cylinder is 0.3cm~0.6cm, and a gap of 1mm~5mm is left between the hammer cylinder and the inner cylinder. The wall thickness of the hammer cylinder is much thicker than that of the inner cylinder, giving it an advantage in terms of its own weight, resulting in a more powerful impact; at the same time, the gap between the hammer cylinder and the inner cylinder allows the hammer cylinder to fall more smoothly and without obstruction.

[0012] Furthermore, this simple manual installation device has a handle height of 10cm to 15cm and a width of 10cm to 15cm. The handle size matches the width of a human hand, making operation more comfortable.

[0013] The advantages of this simple manual installation device for soil breathing rings are that it effectively protects the breathing ring and prevents damage during the process of hammering it into the soil. At the same time, it makes the breathing ring more evenly stressed and prevents it from tilting, resulting in better placement of the breathing ring and thus ensuring the accuracy of carbon and nitrogen emission monitoring. The device is simple in structure, small in size, easy to operate, portable, and inexpensive, and can effectively meet the needs of researchers in placing soil breathing rings during carbon and nitrogen emission monitoring.

[0018] Example 1

[0019] A simple manual installation device for a soil breathing ring includes a fixed base 1 and a manual hammer 2. The fixed base 1 includes an inner cylinder 1-1 and a placement cylinder 1-2 integrally formed from top to bottom and coaxially arranged. The outer diameter of the inner cylinder 1-1 is smaller than the outer diameter of the placement cylinder 1-2. The interior of the placement cylinder 1-2 is used to place the soil breathing ring 4. The manual hammer 2 includes a hammer cylinder 2-1 and a handle 2-2 disposed on the hammer cylinder 2-1. The hammer cylinder 2-1 of the manual hammer 2 is movably fitted outside the inner cylinder 1-1 of the fixed base 1. Both the fixed base 1 and the manual hammer 2 are made of solid iron plate.

[0020] The outer diameter of the hammer cylinder 2-1 is the same as that of the placement cylinder 1-2, both being 20.5cm. The outer diameter of the inner cylinder 1-1 is 1.1cm smaller than that of the placement cylinder 1-2, i.e., 16.4cm. The height of the hammer cylinder 2-1 is 30cm. The wall thickness of the hammer cylinder 2-1 is 2cm, and the wall thickness of the inner cylinder 1-1 is 0.4cm. A 1mm gap is left between the hammer cylinder 2-1 and the inner cylinder 1-1.

[0021] The handle 2-2 includes two symmetrically arranged U-shaped components on the side wall of the hammer cylinder 2-1. The handle 2-2 is 14cm high and 10cm wide.

[0022] The working process of the simplified manual installation device for the soil breathing ring in this embodiment is as follows: place the soil breathing ring 4 inside the placement cylinder 1-2 of the fixed base 1, and then fit the hammer cylinder 2-1 of the manual hammer 2 outside the inner cylinder 1-1 of the fixed base 1; after the installation is completed, firmly grasp the handles 2-2 on both sides with both hands and pull upwards to lift the manual hammer 2. When the manual hammer 2 reaches a certain height and has not detached from the inner cylinder 1-1, release your hands to allow the manual hammer 2 to fall freely and strike the placement cylinder 1-2 of the fixed base 1, thereby hammering the breathing ring 4 into the soil. Repeat the above operation until the breathing ring 4 reaches the predetermined depth.

[0023] Example 2

[0024] A simplified manual installation device for a soil breathing ring, compared to embodiment 1, further includes a positioning bolt 3; both the wall of the hammer cylinder 2-1 and the wall of the inner cylinder 1-1 have axially oriented slots, and the positioning bolt 3 passes through the slots of the hammer cylinder 2-1 and the inner cylinder 1-1 and is fixed by a nut. Specifically, the hammer cylinder 2-1 and the inner cylinder 1-1 are concentric cylinders with coincident axes, and both the walls of the hammer cylinder 2-1 and the inner cylinder 1-1 have a slot for positioning. Bolt 3 passes through the walls of hammer cylinder 2-1 and inner cylinder 1-1 in sequence and is fixed by nuts. Alternatively, two strip-shaped through slots are opened on the walls of hammer cylinder 2-1 and inner cylinder 1-1 respectively, and both are located on the same longitudinal section plane passing through the longitudinal axis. The positioning bolt 3 passes through the strip-shaped through slot on one side of hammer cylinder 2-1 and inner cylinder 1-1 in sequence and enters the interior of inner cylinder 1-1. Then it passes through the strip-shaped through slot on the other side of inner cylinder 1-1 and hammer cylinder 2-1 in sequence and is fixed by nuts.

[0025] The working process of the simplified manual installation device for the soil breathing ring in this embodiment is as follows: Place the soil breathing ring 4 inside the placement cylinder 1-2 of the fixed base 1, and then fit the hammer cylinder 2-1 of the manual hammer 2 outside the inner cylinder 1-1 of the fixed base 1. Rotate and adjust the hammer cylinder 2-1 of the manual hammer 2 so that the strip groove of the hammer cylinder 2-1 and the inner cylinder 1-1 are aligned. At this time, pass the positioning bolt 3 through the strip groove of the hammer cylinder 2-1 and the inner cylinder 1-1 in sequence and fix it with the nut. After the installation is completed, hold the handles 2-2 on both sides tightly with both hands and pull upward to lift the manual hammer 2. When the manual hammer 2 reaches the maximum height, release the hands to let the manual hammer 2 fall freely and hit the placement cylinder 1-2 of the fixed base 1, thereby hitting the breathing ring 4 into the soil. Repeat the above operation until the breathing ring 4 reaches the predetermined depth.

[0026] In addition, when the breathing ring 4 needs to be placed too deep and it is difficult to drive it into the soil using the weight of the hammer 2 itself, the hammer 2 can be pushed by hand to gain more kinetic energy and drive the breathing ring 4 into the soil.
