Description

Technical Field

[0001] The present invention belongs to the technical field of forestry carbon sinks, and specifically relates to a forestry carbon sink measurement device for forestry environmental data. Background Art

[0002] Forestry carbon sink measurement is to estimate and measure five carbon pools: above-ground biomass, below-ground biomass, litter, dead wood, and soil organic carbon. When measuring the litter carbon pool, it is necessary to collect some litter samples and measure their wet weight and dry weight, so as to calculate the moisture content and carbon content rate of the litter, and then calculate the dry weight and carbon storage of the litter per unit area, which is convenient for estimating the carbon storage of the entire forestry litter.

[0033] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] Example 1:

[0035] As Figures 1 to 3 shown, a forestry carbon sink measurement device for forestry environmental data includes a moving bottom plate 1, a sampling device 2 is arranged on the surface of the moving bottom plate 1, a classification storage device 3 is arranged on one side of the sampling device 2, a drying component 4 is arranged inside the classification storage device 3, universal wheels 6 are fixedly installed at the four corners of the lower surface of the moving bottom plate 1, and a pushing handle 7 is arranged on one side of the upper surface of the moving bottom plate 1;

[0036] The sampling device 2 includes threaded holes formed on the surface of the moving bottom plate 1. A sampling cylinder 201 is threadedly connected inside the threaded holes. A rotating rod is rotatably connected inside the sampling cylinder 201. A spiral conveyor blade 202 is arranged on the outer surface of the rotating rod. A plurality of digging teeth 203 are annularly arranged at the bottom of the sampling cylinder 201. A connecting bracket is arranged on the upper surface of the sampling cylinder 201. A connecting shaft is fixedly installed at the top of the connecting bracket. Guide rails 204 are formed on both sides of the upper surface of the moving bottom plate 1. A bearing member is slidably connected inside the guide rails 204. A first motor 205 is arranged inside the bearing member. The output end of the first motor 205 is connected to the connecting shaft. A support member 206 is rotatably connected to the outer surface of the connecting bracket. Both ends of the support member 206 are slidably connected inside the guide rails 204. The support member 206 is fixedly installed with a bearing member through a clamping column. A second motor 207 is fixedly installed on the upper surface of the sampling cylinder 201. The output end of the second motor 207 is connected to the rotating rod. A discharge pipe 208 is fixedly installed on the side surface of the sampling cylinder 201. The length of the bearing member is greater than the length of the discharge pipe 208. A discharge pipe 209 is fixedly installed at one end of the discharge pipe 208. The sampling device 2 further includes first chutes formed on both sides of the lower surface of the moving bottom plate 1. An L-shaped support plate 210 is slidably connected inside the first chutes. A reset spring 211 is fixedly installed at one end of the L-shaped support plate 210. One end of the reset spring 211 is fixedly installed inside the first chutes. A brush plate 212 is fixedly installed at the other end of the L-shaped support plate 210. The brush plate 212 is closely attached to the outer surface of the sampling cylinder 201.

[0037] In this embodiment: First, the debris such as fallen leaves on the soil surface is removed by the raking component 5. Then, the first motor 205 is started to drive the connecting shaft to rotate. The connecting shaft drives the sampling cylinder 201 to rotate through the connecting bracket, so that the sampling cylinder 201 and the first motor 205 and the support member 206 at the top move downward. The bearing member and the support member 206 on the outer surface of the first motor 205 slide inside the guide rails 204. The digging teeth 203 at the bottom of the sampling cylinder 201 facilitate the sampling cylinder 201 to penetrate into the soil. As the sampling cylinder 201 moves downward, the soil will enter the surface of the spiral conveyor blade 202 inside the sampling cylinder 201. Then, the sampling cylinder 201 is reset and slid. Then, the second motor 207 is started to drive the rotating rod to rotate. The rotating rod drives the spiral conveyor blade 202 to rotate, so as to input the soil into the inside of the discharge pipe 208 and then discharge it outward through the discharge pipe 209. The soil at different depths can be sampled and collected, replacing manual collection of soil samples at different depths, improving the work efficiency. Detecting the soil at different depths can more effectively and accurately calculate the capacity of the entire soil carbon pool, improving the accuracy of forestry carbon sink measurement;

[0038] During the process of the sampling cylinder 201 sliding downward and penetrating into the soil, some soil will adhere to the thread grooves on the surface of the sampling cylinder 201. During the reset sliding process, due to the supporting force of the reset spring 211, the L-shaped support plate 210 drives the brush plate 212 at one end to squeeze the surface of the sampling cylinder 201, so that the brush plate 212 always closely adheres to the thread grooves on the surface of the sampling cylinder 201. Then, during the sliding process of the sampling cylinder 201, it frictional contacts with the brush plate 212 to clean the soil attached to the surface of the sampling cylinder 201, ensuring the cleanliness of the surface of the sampling cylinder 201, making the rotation smooth during the next sampling process, and ensuring the stability of the normal operation of the device.

Grooves are provided on the surface of the bearing plates 302, and weighing devices 303 are arranged inside the grooves. The classification storage device 3 further includes fixing members fixedly installed on the lower surface of the bearing plates 302. A first lead screw 306 is threadedly connected inside the fixing members. One end of the first lead screw 306 is rotatably connected to the inner side wall of the storage box 301. A number of third motors 304 are fixedly installed on the housing of the side surface of the storage box 301 far from the sampling cylinder 201.

[0041] In this embodiment: During the process of the discharge pipe 209 discharging soil outward, first start the lowermost third motor 304 to drive the first lead screw 306 to rotate. The rotation of the first lead screw 306 drives the fixing member to move, the fixing member drives the upper bearing plate 302 to move, and the bearing plate 302 drives the upper weighing device 303 and the rectangular enclosure 305 to move. As the discharge pipe 209 continuously discharges soil, the bearing plate 302 moves slowly, so that the soil on the surface of the weighing device 303 is evenly distributed. A number of bearing plates 302 sequentially bear different layers of soil, and then the soil is weighed by the weighing device 303.

A belt is lapped on the outer surfaces of the second pulleys at the same level and the first pulley 405. Several exhaust holes are formed on the surface of the storage tank 301.

[0044] In this embodiment: The collected soil contains moisture. After weighing, in order to reduce the influence of moisture on the measurement result, the soil needs to be dried. Start the hot air blower 404 to input hot air into the main air pipe 403, and then input it into several branch air pipes 402, and then spray it out through several nozzles below the drying ring frame 401. During the drying process, the staff starts the fourth motor 406 to drive the rotating shaft 407 to rotate. The rotating shaft 407 drives the second pulley to rotate, and drives the corresponding first pulley 405 on the other side and the internal drying ring frame 401 to rotate through the belt. The sealing ring ensures the sealing performance between one end of the drying ring frame 401 and one end of the branch air pipe 402. During the drying and jetting process, the drying ring frame 401 rotates, thereby improving the drying efficiency and drying quality. After drying, weigh it with a weighing device, calculate the soil moisture content. The soil sample after removing moisture can make the analysis result more accurate, facilitate the calculation of carbon density and carbon storage, and improve the accuracy of forestry carbon sink measurement;

[0045] A filter screen is provided above the exhaust hole. The function of the filter screen is to prevent dust in the air or soil driven by strong wind from entering the interior of the storage tank 301 through the exhaust hole, so as to improve the accuracy of the measurement result.

[0046] Embodiment 4:

The staff starts the electric push rods 504 on both sides to drive the prying plates 505 to slide downward, so that one end of the prying plate 505 is closely attached to the upper surface of the soil. Then, the driving motor is started to drive the bidirectional lead screw 502 to rotate. The rotation of the bidirectional lead screw 502 causes the sliding plates 503 on both sides to slide away from each other. The sliding plates 503 drive the electric push rods 504 and the prying plates 505 below to slide synchronously, so as to clean the sundries above the soil to be collected, and thus facilitate the subsequent soil collection operation.
