Description

Technical Field

[0001] The utility model relates to the technical field of forestry, in particular to an exploration device for forest resource management. Background Art

[0002] Forest resource management is crucial to the maintenance of ecological balance and sustainable development of forestry, and accurate soil exploration is a key link. As the foundation of the forest ecosystem, the nature of soil has a profound impact on tree growth, nutrient circulation and ecosystem stability. Accurately obtaining soil information can help managers scientifically plan forest management, effectively prevent and control pests and diseases, and reasonably respond to climate change. Therefore, forest soil sampling devices are of great significance.

[0003] When using a sampling device to sample forest soil, the soil drill has the characteristics of relatively simple structure, easy operation, and no need for complex equipment and technology. Surveyors can easily carry the soil drill to various sampling points in the forest for sampling, which is especially suitable for field surveys in forest areas with complex terrain and inconvenient transportation. Although the soil drill has improved efficiency to a certain extent, it can only obtain a single columnar sample, which cannot meet the needs of soil stratification research at different depths, cannot fully reflect the differences in soil properties in the vertical direction, and can easily cause soil samples of different depths and different properties to mix, so that the obtained soil samples cannot truly reflect the actual situation of each soil layer. Utility Model Content

[0004] The purpose of the utility model is to propose a forest resource management exploration device in order to solve the problem that the existing soil sampling device for forest resource exploration cannot meet the needs of soil stratification research at different depths and cannot fully reflect the differences in soil properties in the vertical direction.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technology: a survey device for forest resource management, comprising a hollow fixed rod, one end of which is provided with a handle, and the other end of which is detachably connected with a sampling barrel, the bottom of which is integrally formed with a cone head, a layered sampling mechanism is provided on the sampling barrel, and a depth adjustment mechanism for adjusting the drilling depth of the sampling barrel is provided on the fixed rod;

[0006] The stratified sampling mechanism cooperates with the sampling tube to realize stratified sampling of soil at different depths, and the sampled soil can be stored and carried.

[0007] As a further description of the above technical solution: the stratified sampling mechanism includes a connecting rod coaxially arranged with the sampling barrel, the interior of the sampling barrel is divided into a plurality of sampling chambers by a partition arranged on the connecting rod, the sampling barrel is provided with collection ports corresponding to the plurality of sampling chambers one by one, and the connecting rod is provided with a cover assembly which cooperates with the collection port to realize the opening and closing of the collection port.

[0008] As a further description of the above technical solution: the stratified sampling mechanism also includes a positioning component for limiting and fixing the connecting rod;

[0009] The positioning assembly comprises a positioning rod arranged on the handle through a fixing block, a pull ring is arranged at the bottom of the positioning rod, and a positioning hole matched with the positioning rod is opened on the handle at the top of the connecting rod.

[0010] As a further description of the above technical solution: the cover plate assembly includes a connecting sleeve mounted on a connecting rod, a sealing cover matching with the collection port is arranged on the connecting sleeve through a bracket rod, and a gasket is arranged on the sealing cover.

[0011] As a further description of the above technical solution: a rubber ring abutting against the inner wall of the sampling tube is arranged on the partition through a slot.

[0012] As a further description of the above technical solution: the depth adjustment mechanism includes a limit plate sleeved on the outside of the sampling barrel, and the limit plate can move along the height direction of the sampling barrel through an adjustment rod.

[0013] As a further description of the above technical solution: the depth adjustment mechanism also includes a locking assembly for limiting and fixing the adjustment rod;

[0014] The locking assembly comprises a mounting seat sleeved on the fixing rod, a guide sleeve sleeved on the outside of the adjusting rod is arranged on the mounting seat through a connecting plate, and a locking bolt is arranged on the guide sleeve.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0016] 1. The cooperation between the stratified sampling mechanism and the sampling cylinder can realize stratified sampling of soil at different depths. Since soil at different depths may have different physical, chemical and biological properties, stratified sampling can accurately obtain soil samples at each layer, more comprehensively reflect the characteristics of the soil, and provide more representative data for soil research and related work. In addition, during the collection process, it can effectively avoid the mixing of soil at different depths when entering the cylinder, ensuring that the soil sample in each collection chamber only comes from a specific depth, thereby improving the accuracy of sampling;

[0017] The design of the collection chamber and cover assembly can well seal the soil sample after sampling, preventing the soil sample from spilling or being contaminated and disturbed by the external environment during the removal of the sampling tube and the subsequent sample transfer and transportation, thus ensuring the integrity and originality of the soil sample, which is conducive to the smooth progress of subsequent laboratory analysis;

[0018] 2. When conducting large-scale forest soil surveys, it is necessary to obtain soil samples of consistent depth at multiple sampling points for comparative analysis. The depth adjustment mechanism enables the sampling tube to drill into the same depth at each sampling point, ensuring the consistency of soil samples at different sampling points in depth, reducing sample errors caused by differences in sampling depth, and improving the reliability and comparability of research results.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 7 The present embodiment provides a forest resource management exploration device, comprising a hollow fixed rod 1, one end of which is provided with a handle 2, and the other end of which is detachably connected with a sampling tube 3, the bottom of which is integrally formed with a cone head 4, and a layered sampling mechanism 5 is provided on the sampling tube 3;

[0030] In the utility model, when sampling forest soil, the sampling staff selects the position where the soil needs to be sampled, and then aims the sampling tube 3 at the soil to be sampled. The staff holds the handle 2 on the top of the fixed rod 1 with both hands, and uses the handle 2 to press the sampling tube 3 at the bottom of the fixed rod 1 downward. The cone head 4 at the bottom of the sampling tube 3 can make the sampling tube 3 concentrate the force on a smaller area when inserting the soil, thereby generating a greater pressure, making it easier to penetrate the soil, and can make the sampling tube 3 more stable when entering the soil, reducing the squeezing and stirring of the surrounding soil. After the sampling tube 3 is inserted into the soil, the stratified sampling mechanism 5 cooperates with the sampling tube 3 to achieve stratified sampling of soil at different depths, and the sampled soil can be stored and carried.

[0031] Specifically, Figure 1 , Figure 2 and Figure 4As shown, the stratified sampling mechanism 5 includes a connecting rod 51 coaxially arranged with the sampling barrel 3. The interior of the sampling barrel 3 is divided into a plurality of sampling chambers by a partition 52 arranged on the connecting rod 51. The sampling barrel 3 is provided with collection ports 31 corresponding to the plurality of sampling chambers one by one, and the connecting rod 51 is provided with a cover assembly 53 for cooperating with the collection port 31 to realize the opening and closing of the collection port 31. The cover assembly 53 includes a connecting sleeve 531 sleeved on the connecting rod 51, and a sealing cover 533 cooperating with the collection port 31 is provided on the connecting sleeve 531 through a bracket rod 532, and a gasket 534 is provided on the sealing cover 533.

[0032] The detailed steps of stratified sampling are as follows: after the sampling tube 3 drills into the soil and reaches the specified depth, the connecting rod 51 is rotated, and the connecting sleeve 531 is driven to rotate when the connecting rod 51 rotates, and the sealing cover 533 connected to the connecting sleeve 531 through the bracket rod 532 moves accordingly. The sealing cover 533 is an arc-shaped plate that fits the inner wall of the sampling tube 3. When the sealing cover 533 is removed, the collection port 31 is connected to the outside world. Under the action of the pressure difference, the outside soil will be pressed or squeezed into the sampling chamber under the combined action of atmospheric pressure and the soil's own gravity. The gasket 534 on the sealing cover 533 is made of rubber material, so that it can be sealed. The cover 533 is in the position of the collection port 31, which can effectively cover the collection port 31. Since each sampling chamber is separated by the partition 52, it is possible to achieve layered sampling of soil at different depths. Soil at different depths may have different physical, chemical and biological properties. This design can accurately obtain soil samples from each layer, more comprehensively reflect the characteristics of the soil, and provide more representative data for soil research and related work. In addition, during the collection process, it can effectively prevent soils at different depths from mixing with each other when entering the sampling tube 3, ensuring that the soil sample in each sampling chamber only comes from a specific depth, thereby improving the accuracy of sampling.

[0033] It should be noted that a rubber ring 522 abutting against the inner wall of the sampling tube 3 is provided on the partition 52 through a slot 521. The bottom of the connecting rod 51 has a smooth end, which abuts against the groove at the top of the cone head 4. Therefore, it can ensure that the connecting rod 51 rotates on the axis of the sampling tube 3. When the connecting rod 51 rotates, the partition 52 will be driven to rotate. The design of the rubber ring 522 on the slot 521 of the partition 52 can ensure that the partition 52 can effectively separate the sampling chambers and avoid mixing of soil between different sampling chambers. On the other hand, when the connecting rod 51 is removed from the sampling tube 3, the soil attached to the inner wall of the sampling tube 3 can be scraped off, which is convenient for the subsequent cleaning of the sampling tube 3.

[0034] Specifically, Figure 1-Figure 3As shown, the stratified sampling mechanism 5 also includes a positioning assembly 56 for limiting and fixing the connecting rod 51. The positioning assembly 56 includes a positioning rod 562 set on the handle 2 through a fixing block 561. A pull ring 563 is set at the bottom of the positioning rod 562. A positioning hole 55 that cooperates with the positioning rod 562 is opened on the handle 54 at the top of the connecting rod 51.

[0035] Among them, the positioning rod 562 is divided into an insertion section in the upper half and a threaded section in the lower half. When the top of the positioning rod 562 is inserted into the positioning hole 55 of the handle 54, the sealing cover 533 cooperates with the rubber gasket 534 to cover the collection port 31, so that the sealing cover 533 will not be offset during the insertion of the sampling tube 3 into the soil, so as to ensure that the sampling tube 3 can be accurately inserted into the soil. When the sampling tube 3 is inserted to the specified depth, the positioning rod 562 is rotated by using the pull ring 563. Under the action of its threaded section, the positioning rod 562 moves downward and disengages from the positioning hole 55 of the handle 54, so that the connecting rod 51 can be rotated by the handle 54, and then the sealing cover 533 can be opened to perform sampling. The stratified sampling work is carried out. When the sampling is completed, the connecting rod 51 is rotated again to make the positioning hole 55 of the handle 54 be located above the positioning rod 562. At this time, the positioning rod 562 is rotated again to make the insertion section of the positioning rod 562 inserted into the positioning hole 55. At this time, the connecting rod 51 is limited and fixed, and the sealing cover 533 blocks the collection port 31. Then the sampling tube 3 is taken out. At this time, the design of the sampling chamber and the sealing cover 533 can well seal the soil sample after sampling, prevent the soil sample from being spilled or contaminated and disturbed by the external environment during the removal of the sampling tube 3 and the subsequent sample transfer and transportation, thereby ensuring the integrity and originality of the soil sample, which is conducive to the smooth progress of subsequent laboratory analysis.

[0036] Specifically, Figure 1 , Figure 6 and Figure 7 As shown, a depth adjustment mechanism 6 for adjusting the drilling depth of the sampling tube 3 is provided on the fixed rod 1, and the depth adjustment mechanism 6 includes a limit plate 61 mounted on the outside of the sampling tube 3, and the limit plate 61 can move along its height direction on the sampling tube 3 through the adjustment rod 62. The depth adjustment mechanism 6 also includes a locking assembly 63 for limiting and fixing the adjustment rod 62. The locking assembly 63 includes a mounting seat 631 mounted on the fixed rod 1, and a guide sleeve 633 mounted on the outside of the adjustment rod 62 is provided on the mounting seat 631 through a connecting plate 632, and a locking bolt 634 is provided on the guide sleeve 633.

[0037] When conducting large-scale forest soil surveys, it is necessary to obtain soil samples of consistent depth at multiple sampling points for comparative analysis. At this time, the locking bolt 634 on the guide sleeve 633 can be loosened, and the pressure of the locking bolt 634 on the adjusting rod 62 becomes smaller. The sampling staff holds the adjusting rod 62 to move the limit plate 61 on the sampling tube 3, and the limited depth can be adjusted in conjunction with the scale on the sampling tube 3. Then, the locking bolt 634 is tightened again to fix the adjusting rod 62, thereby fixing the limit plate 61 on the sampling tube 3. When the sampling tube 3 is inserted into the soil, the limit plate 61 on the sampling tube 3 will play a limiting role. When the limit plate 61 is against the soil surface, the sampling tube 3 can be stopped from being pressed down, so that the sampling tube 3 can be drilled into the same depth at each sampling point, ensuring the consistency of the depth of soil samples at different sampling points, reducing the sample error caused by the difference in sampling depth, and improving the reliability and comparability of the research results.
