Description

Technical Field

[0002] Forest carbon sink refers to the process in which forest plants absorb carbon dioxide from the atmosphere and fix it in vegetation or soil, thereby reducing the concentration of the gas in the atmosphere. Forests are the largest carbon pool in terrestrial ecosystems and play a very important and unique role in reducing the concentration of greenhouse gases in the atmosphere and mitigating global warming. After determining the sampling area in the process of carbon sink measurement, it is necessary to use a soil sampling device to sample the soil in the area and accurately measure the organic carbon content in the soil sample. Chinese patent: CN212780030U discloses a field soil collection device, including a support column, the support column is hollow inside, and a connecting shaft rotatably connected to it is coaxially arranged at its bottom, and a soil collecting pipe fixedly connected to it is arranged at one end of the connecting shaft away from the support column, and a cutting pipe fixedly connected to it is arranged at one end of the soil collecting pipe away from the connecting shaft, and a sawtooth mouth is arranged at the bottom of the cutting pipe. A motor connected to the connecting shaft is also arranged in the support column, and the motor is fixedly connected to the support column. Handles fixedly connected to it are symmetrically arranged on both sides of the end of the support column away from the connecting shaft, and pedals fixedly connected to it are arranged on both sides of the end of the support column close to the connecting shaft.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4The utility model provides a technical solution: a forest and grass carbon sink field sampling device, including a sample storage tube 1, the bottom end of which is detachably connected to a digging part 2, the sample storage tube 1 includes two relatively arranged half-tube bodies 101, one of which is provided with connecting slides 102 on both side end surfaces of one half-tube body 101, and the other half-tube body 101 is provided with connecting slides 103 on both side end surfaces, each connecting slide 102 is slidably connected to the corresponding side connecting slide 103, connecting parts are provided on the outer walls on both sides of the top of each half-tube body 101, and are fixedly connected with handrails 3 through the connecting parts, each handrail 3 is fixedly connected with a water tank 4, a waterway is provided inside each half-tube body 101, and a water outlet pipe is provided on the surface of one side of each water tank 4, one end of the water outlet pipe is connected to one end of the waterway, and the other end of the waterway is opened and arranged on the inner wall of the bottom end of the half-tube body 101.

[0022] It should be noted that a switch valve is provided on the water outlet pipe of each water tank 4 so as to control the smoothness of the waterway.

[0023] See also Figures 2 to 4 Each connecting piece includes two connecting ear plates 104 with through holes, and the two connecting ear plates 104 are respectively arranged on the outer walls on both sides of the top of the corresponding half tube body 101. Bolts 105 are inserted into the through holes of the two connecting ear plates 104 on the same side, and a nut is threadedly connected on one end of each bolt 105.

[0024] When the two half-tube bodies 101 are slidably spliced ​​together through the connecting slide bar 102 and the connecting slide groove 103 and the upper and lower ends are aligned, the positions of the two sets of connecting ear plates 104 correspond. The two half-tube bodies 101 can be limited by inserting bolts 105 in the connecting ear plates 104 on the same side and tightening them with nuts, so that the two half-tube bodies 101 cannot be relatively displaced, thereby ensuring stability during use. When it is necessary to take out the soil samples stored in the two, the limit of the bolt 105 can be released, and the two can be slid apart to take out the soil sample completely, thereby avoiding destroying the original layered structure of the soil sample and reducing the carbon sink detection error.

[0025] Furthermore, each water channel includes a water trough 109 arranged inside the corresponding half-tube body 101, the top of the water trough 109 is connected to one end of the connecting hole 108, the other end of the connecting hole 108 is opened and arranged on the outer wall of the half-tube body 101 and connected to one end of the water outlet pipe of the water tank 4, and the bottom of the water trough 109 is connected to one end of the water outlet hole 110, and the other end of the water outlet hole 110 is opened and arranged on the inner wall of the half-tube body 101.

[0026] After the sample storage tube 1 is inserted into the soil as a whole, the switch valve on the outlet pipe of each water tank 4 is opened before recovery, and the water inside the water tank 4 will enter the connecting hole 108 through the outlet pipe, and flow from the connecting hole 108 through the water trough 109 and finally flow out from the outlet hole 110, so as to humidify the bottom of the soil inside the sample storage tube 1 to increase the soil adhesion and avoid the situation where the soil sample leaks from the bottom when the sample storage tube 1 is recovered due to loose soil caused by relative dryness. In order to reduce the possibility of affecting the accuracy of carbon sink detection after soil humidification, the sampling depth of the sample storage tube 1 can be kept greater than the predetermined detection depth in actual use, so as to humidify the soil depth that does not need to be detected.

[0027] Furthermore, each half tube 101 is provided with a plurality of water delivery grooves 109 , and all water delivery grooves 109 are evenly distributed in parallel in the extension direction of each half tube 101 , and the top of each water delivery groove 109 is connected to a connecting groove 111 coaxially arranged on the half tube 101 , and the connecting groove 111 is connected to one end of the connecting hole 108 .

[0028] The top ends of the plurality of water delivery grooves 109 are connected to one end of the connection hole 108 via a connecting groove 111 , and the axially distributed water outlet holes 110 can improve the humidification speed and uniformity of the soil, thereby improving the utilization efficiency.

[0029] Furthermore, corresponding thread grooves 107 are provided on the inner walls of the bottom ends of the two half-tubes 101 , and the digging parts 2 are threadedly connected through the thread grooves 107 on both sides.

[0030] The thread groove 107 arranged on the inner wall of each half tube 101 is a complete half, so when two half tubes 101 are spliced ​​together, a complete thread groove 107 can be formed, and the digging part 2 is connected through this complete thread groove 107.

[0031] Furthermore, the excavating part 2 includes a tapered tube 201 , and a threaded tube 202 is provided at the top end of the tapered tube 201 , and the threaded tube 202 is threadedly connected to the thread grooves 107 on both sides.

[0032] By installing a conical tube 201 at the bottom end of the sample storage tube 1, the ground contact area can be reduced, so that the sample storage tube 1 can be better inserted into the soil and is relatively labor-saving to use.

[0033] Furthermore, spiral earth-digging convex patterns 203 are provided on the outer wall of the conical tube 201 .

[0034] By providing the spiral digging ridges 203 on the outer wall of the conical tube 201, the digging efficiency can be further improved, and the force required to be applied when rotating the whole to insert into the soil and recover can be reduced.

[0035] Working principle: When the two half-tube bodies 101 are slidably spliced ​​together through the connecting slide bar 102 and the connecting slide groove 103 and the upper and lower ends are aligned, the positions of the two sets of connecting ear plates 104 correspond, and the two half-tube bodies 101 can be limited by inserting bolts 105 in the connecting ear plates 104 on the same side and tightening them with nuts, so that the two half-tube bodies 101 cannot move relative to each other. Then, the tapered tube 201 is threadedly connected to the thread groove 107 at the bottom end of the half-tube body 101 through the threaded tube 202, and the bottom end of the tapered tube 201 touches the ground. The whole is rotated by the handrail 3, and the outer wall of the tapered tube 201 is moved to the ground through the spiral digging convex pattern 203. The soil is excavated inside to drive the sample tube 1 as a whole into the soil. The soil sample will automatically enter the sample tube 1 through the conical tube 201. The switch valve on the water outlet pipe of the water tank 4 is opened to inject water into several water troughs 109. The water flows out from the water outlet 110 to humidify the soil at the bottom of the sample tube 1, thereby increasing the soil adhesion and avoiding the situation where the soil sample leaks from the bottom when the sample tube 1 is recovered due to loose soil caused by relative dryness. Then, the whole is recovered by rotating in the opposite direction, and the two half tubes 101 are slid and separated after the restriction of the bolt 105 is released, so that the soil sample can be completely taken out, thereby avoiding destroying the original layered structure of the soil sample and reducing the error of carbon sink detection.

[0036] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
