Description

Technical Field

[0001] The present invention relates to the technical field of soil collection equipment, and in particular to a soil collection equipment based on land reclamation and protection and utilization. Background Art

[0002] In the context of land management, protection and utilization, accurate acquisition of mountain soil information is of key significance. As an important part of the land, the soil conditions of mountains affect many aspects such as ecological balance, agricultural development and engineering construction. However, the mountainous terrain is complex, with steep terrain and large undulations. Conventional soil collection equipment is difficult to operate effectively, and there are problems such as inconvenient operation and low sampling efficiency. At the same time, the soil characteristics of different mountains vary significantly, and the lack of targeted equipment will lead to inaccurate soil data acquisition.

[0003] A soil sample collection device is disclosed in the patent publication number CN114166551A, including a support frame, a protective tube is arranged at the central axis of the support frame, a plurality of movable holes are opened on the outer surface of the protective tube, a hydraulic telescopic rod is fixedly connected to the inside of the protective tube, and a motor is fixedly connected to the top of the hydraulic telescopic rod. The soil sample collection device, through the setting of the device, the drill bit can first drill holes in the soil, thereby facilitating the subsequent collection of soil. When a certain position is reached, the adjustment of the hydraulic telescopic rod can make the convex ring squeeze the collection tube, and under the action of squeezing, the collection tube can be moved out of the protective tube to achieve the purpose of soil collection. When the soil collection is completed, the collection tube will enter the interior of the collection tube, thereby protecting the soil and preventing soils of different depths from mixing together, which affects the collection effect.

[0004] The prior art has the following defects: It is impossible to collect soil at the center of the drill tube: when the drill tube is inserted into the soil, it is easy to cause soil disturbance, destroy the original structure, and affect the judgment of the true condition of the soil. The soil at the center of the drill tube is less disturbed by the outside world and can more truly reflect the original characteristics of the soil, such as nutrient content, texture structure, etc. Therefore, it is necessary to set up a structure in the drill tube to collect soil at the center position, so as to obtain more representative soil samples, provide a reliable basis for land reclamation and protection and utilization, make more scientific and reasonable planning decisions, and achieve the effect of improving the utilization and protection effectiveness of soil resources.

[0005] Unable to accurately locate the direction perpendicular to the horizontal line in steep slopes for soil collection: When conducting a large-scale soil fertility survey, it is necessary to conduct a comprehensive analysis of the steep slope soil data with the soil data of other terrains such as plains and gentle slopes. Sampling perpendicular to the horizontal line can eliminate the interference of slope factors on soil samples, making the soil data of different terrains comparable. However, the existing equipment cannot accurately locate the direction perpendicular to the horizontal line in steep slopes, so that the drill tube cannot be inserted vertically into the soil, resulting in a lack of consistency and representativeness of the samples, affecting the subsequent analysis results. Therefore, it is necessary to set up a structure that can accurately locate the direction perpendicular to the horizontal line in the steep slope, so as to clearly show the true characteristics of the soil layers at each depth, ensure the consistency and comparability of data at different sampling points, and achieve the effect of improving the utilization and protection efficiency of steep slope soil resources.

Therefore, it is more convenient for surveyors to carry foldable manual machinery for soil collection.

[0051] During operation, when it is necessary to collect soil perpendicular to the ground, pull the support vertical plate 21 at the steering block 23, place the head and tail bonding plates 25 on the steep ground, and fix them with fixing bolts 26 to complete the construction of a platform parallel to the ground.

[0052] When it is necessary to collect soil perpendicular to the horizontal plane, first fix the head fitting plate 25 on the steep slope, then rotate the steering block 23 ninety degrees to make the supporting vertical plate 21 perpendicular to the supporting horizontal plate 1, and then raise the lower end of the supporting horizontal plate 1 until the ball 13 rolls to the middle position in the swing groove 12. At this time, the supporting horizontal plate 1 is parallel to the horizontal line, and the supporting vertical plate 21 is perpendicular to the horizontal line. Then move the supporting vertical plate 21 downward at the steering block 23 until the tail fitting plate 25 is close to the ground under the rotation of the adjusting shaft 27. At this time, tighten the positioning bolts 24 in the slide groove 22 to fix the supporting vertical plate 21, and the platform parallel to the horizontal line can be built.

[0053] During collection, the externally threaded drill tube 321 is installed at the inner screw groove 11, the second clamping groove 313 inside the top cover 311 is clamped with the externally threaded drill tube 321, the handle 314 is manually turned counterclockwise, the externally threaded drill tube 321 is drilled into the soil through the drill teeth 322, and the top cover 311 is removed.

[0054] Then, the components of the coring barrel in the initial state are placed inside the externally threaded drill barrel 321 and the storage groove 323, the first engaging groove 312 inside the top cover 311 is engaged with the first rotating block 331, and the handle 314 is manually turned clockwise, and the first rotating block 331 rotates in the arc groove 344 of the first fixed block 341, and the second rotating block 332 is driven to rotate in the arc groove 344 of the second fixed block 342 through the connecting shaft 333, and then the arc-shaped racks 334 and the corresponding rotating gears 354 inside the first rotating block 331 and the second rotating block 332 drive the multiple rotating shafts 353 to rotate synchronously, so that the multiple coring plates 351 rotate around the multiple rotating shafts 353 as the axis under the connection of the offset connecting plate 352, and finally merge into a coring barrel that can collect central soil.

[0055] Then, the coring tube is taken out to complete the collection of soil at the center of the external threaded drill tube 321.
