Description

Technical Field

[0001] The invention relates to the technical field of environmental monitoring, and in particular to a forestry microenvironment monitoring method. Background Art

[0002] The existing forestry microenvironment monitoring device needs to monitor the microenvironment of forestry soil, and the forestry soil needs to be sampled during the monitoring process. The existing forestry microenvironment monitoring device samples by drilling a sampler into the soil layer. Only soil of a certain fixed depth can be drilled during one sampling process. Considering the objectivity and accuracy of the monitoring results, multiple samplings are required to drill the soil of soil layers at different depths. Therefore, the sampling efficiency of the existing soil sampling device is low, which brings a heavy burden to the forestry microenvironment monitoring work. Patent documents have now been made to improve this.

[0003] For example, Chinese patent CN115753191B discloses a forestry microenvironment monitoring method, comprising the following steps: S1: moving a forestry inspection vehicle to a monitoring position; S2: inserting a sampling device on the forestry inspection vehicle into the soil at a corresponding depth; S3: disconnecting the sampled soil, retracting the sampling device onto the forestry inspection vehicle, and completing the sampling process; S4: quantitatively weighing the above-mentioned soil sample, and testing the soil standard solution through a testing instrument; the sampling device in S1 comprises a frame, an outer sleeve is arranged in the frame, a sampling mechanism is arranged in the outer sleeve, a connecting shaft is driven to rotate by a driving assembly, so that a drill bit at the lower end of the inner cylinder body makes a downward drilling movement, and a connecting rope pulls a plurality of sealing plugs, so that soils of different depths can enter storage slots of different heights respectively, so that the device can take out soil samples of different depths through one sampling, effectively improving the sampling efficiency and reducing the labor burden of forestry microenvironment monitoring work.

[0004] Although the equipment in the above document is designed to sample soil at different depths, it has obvious defects in actual use, such as:

[0005] After the soil is drilled, the entire cylinder will enter the soil layer, and then the cylinder will fit into the soil. The deep soil has a large water content and will be compacted under compression. When the sealing plug is opened, the soil will not actively enter the inner side of the storage tank. Even if it enters, it is only a small amount of loose soil, which cannot meet the needs of the experiment.

[0006] Therefore, a device suitable for a forestry microenvironment monitoring method that can fully sample is now designed to address such deficiencies. Summary of the invention

Beneficial Effects

[0024] The present invention provides a forestry microenvironment monitoring method. Compared with the existing technology, it has the following beneficial effects:

[0025] (1) The forestry microenvironment monitoring method combines a basic driving mechanism and a drilling sampling mechanism. The two mechanisms can be driven by a motor so that the inner drill tube can drill downwards. During the descent, the tire is fixed to limit the position of the entire device. After the inner drill tube descends to the limit position, the inclined shovel can be unfolded and the rotation of the threaded column can be disconnected. Only the inner drill tube is driven to rotate, so that the surrounding soil is actively scraped off by the inclined shovel and directed to the storage tank for storage, so as to extract sufficient samples. After rising, it can be actively unlocked to facilitate sample taking, which is satisfactory for current use.

[0026] (2) The forestry microenvironment monitoring method is provided with a material storage trough on the inner side of the inner drill tube, and a bevel shovel is installed on both sides of the inner drill tube by opening a storage trough, and is used in conjunction with a push rod, a first arc block, a second arc block and a semi-arc plate. The arrangement of these structures can unfold the bevel shovel by pulling the cable after the inner drill tube descends to the limit position, which is convenient for subsequent sampling of a sufficient amount of soil, and can also actively reset the bevel shovel after rising so that it will not collide with the outer tube frame, thereby ensuring the overall stability of the equipment.

[0027] (3) The forestry microenvironment monitoring method is to install sealed door panels on both sides of the storage tank through the material extraction port, and use them in conjunction with the plug ring, the push rod block and the latch rod. The arrangement of these structures can use the round ball and the convex block to resist each other after the inner drill tube rises to the limit position, so that the push rod block is inserted into the plug ring to squeeze the latch rod out of the plug ring. At this time, the sealed door panel is unlocked, and the staff can take out the sealed door panel through the disassembly port to take out the sample, which is convenient for use.

[0028] (4) The forestry microenvironment monitoring method is to install a sliding seat and a separation plate in a rectangular guide groove on one side of the rectangular frame, and use it in conjunction with a disc frame. The arrangement of these structures can enable the disc frame to squeeze the two separation plates when the inner drill tube drives the arc-shaped sliding seat to descend, so that the arc-shaped plate contacts the tire to fix it, so that the whole equipment can be stable when in use.

DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0047] See also Figure 1-16 The present invention provides a technical solution: a forestry microenvironment monitoring method, which specifically includes the following steps:

[0048] S1. Moving: Before use, use the tire 113 in the basic driving mechanism 1 to move the entire device to a specified position;

[0049] S2, limited drilling: after the movement is completed, the motor 105 is started, and the motor 105 drives the rotating rod 106 to rotate. The rotation of the rotating rod 106 drives the gear plate 111 and the pulley 107 to rotate respectively. The inner drill tube 201 is driven to rotate by the transmission of the belt 108 and the mutual engagement of the two gear plates 111. At this time, the convex block 123 and the concave groove 202 are relatively driven to rotate the inner drill tube 201. The connection between the polygonal rod 110 and the polygonal groove 205 also causes the threaded column 204 to rotate under the limit of the limit guide rod 206. At this time The inner drill tube 201 rotates and is pushed down by the threaded column 204, and the inner drill tube 201 drills the ground. When the inner drill tube 201 descends, it will use the circular sliding groove 230 to drive the arc-shaped slide seat 121 to descend along the lifting port 125. When the arc-shaped slide seat 121 descends, it will drive the two disc frames 120 to descend under the limiting effect of the vertical guide plate 119. After the disc frames 120 descend, they will squeeze the two separation plates 118, and under the limiting effect of the sliding seat 115, the arc-shaped sheet 117 will be pushed to contact the tire 113 to limit the tire 113, so that the whole device is fixed;

[0050] S3, the inclined shovel is opened: after the inner drill tube 201 is lowered to the limit position, the cable 220 is stretched, and the cable 220 is tightened to pull the semi-arc plate 217 upward, and the rise of the semi-arc plate 217 will use the vertical pressure rod 214 to pull the second arc block 216 and the first arc block 215 upward, and the second arc block 216 is inserted into the inner side of the insertion and pushing groove 213 to squeeze the push rod 212, and under the sliding action of the rotating slide block 211, the push rod 212 pushes the inclined shovel 210 from the inner side of the storage groove 208 to contact the external soil;

[0051] S4, switching: after the semi-arc plate 217 rises, the button 221 is also pressed to start the electric telescopic rod 109. After the electric telescopic rod 109 is started, the polygonal rod 110 is pulled up and separated from the threaded column 204;

[0052] S5, sampling: After the threaded column 204 is separated from the polygonal rod 110, the motor 105 starts to rotate in the reverse direction. At this time, after the threaded column 204 is separated from the polygonal rod 110, the rotation of the rotating rod 106 will not drive the threaded column 204 to rotate, but the inner drill tube 201 will be driven to rotate in the reverse direction under the meshing of the two gear plates 111. Since the inclined shovel 210 is supported and launched to rotate in the reverse direction, the soil of the edge soil layer will be scraped off and the soil will be guided into the storage tank 207 for storage. After the inclined shovel 210 completely scrapes the range of soil that it can scrape, it stops, and then goes to step S6;

[0053] S6, reset and unloading: after the sampling is completed, the electric telescopic rod 109 is started again to drive the polygonal rod 110 to descend and dock with the polygonal groove 205. After the polygonal rod 110 and the polygonal groove 205 are docked, the motor 105 continues to start the reverse direction. At this time, the threaded column 204 is driven to reverse and will drive the inner drill tube 201 to rise. After the cable 220 is relaxed, the semi-arc plate 217 is pulled down by the second spring 218, so that the vertical pressure rod 214 pushes the first arc block 215 to insert into the insertion and pushing groove 213, and the second arc block 216 is pushed out of the insertion and pushing groove 213. The push rod 212 is squeezed by the first arc block 215, and the push rod 212 is used to retract the inclined shovel 210 to the inner side of the storage groove 208 to close the storage groove. 208 is closed until the inner drill tube 201 completely rises and returns to the inner side of the outer tube frame 102 and then stops. After the inner drill tube 201 rises to the limit position, the round ball 229 and the annular resistance plate 124 abut against each other to push the round vertical rod 226 down as a whole. After the round vertical rod 226 descends, several push rod blocks 227 are mobilized to insert the plug ring 223 to squeeze the latch rod 224 out of the plug ring 223. At this time, the sealing door plate 222 loses its limit, and the sealing door plate 222 is taken out from the disassembly port 122. At this time, the storage tank 207 is exposed, and the soil inside the storage tank 207 is taken out. After taking it out, the sealing door plate 222 is re-connected with the material taking port 209, and the soil sampling is completed.
