Description

Technical Field

[0001] This invention belongs to the field of soil survey technology, and in particular relates to a soil survey whole-section soil sample collection device. Background Technology

[0002] The third national soil survey is an important method for identifying soil types and distribution patterns, and for ascertaining the quantity and quality of soil resources. The survey results provide scientific support for soil classification, planned utilization, improvement and fertilization, and protection and management, and also provide a basis for decision-making in the formulation of major policies for economic, social, and ecological construction. Among various soil samples, whole-segment soil samples are the most important data.

[0003] Whole-soil samples, characterized by their ability to preserve the soil's original natural state to the greatest extent possible, accurately reflecting the soil's structure and properties, are the most important samples among the many collected in this survey. Whole-soil samples are taken from soil profiles, which are external reflections of the soil's intrinsic properties and a mirror of the geographical landscape. High standards are required during the collection of whole-soil samples; they must not be deformed, collapsed, or contaminated.

[0004] Currently available soil sampling devices are prone to collapse when soil moisture content is high, making it impossible to collect complete samples from the entire section. This leads to sampling failures. Furthermore, when the pre-excavated profile is damaged or collapses, it needs to be re-excavated, taking anywhere from two hours to a day, severely impacting project progress and significantly increasing sampling costs. Therefore, there is an urgent need to improve existing soil sampling devices and provide a new device for collecting complete soil samples for soil surveys. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a soil sample collection device that is reasonably designed, simple in structure, capable of rapidly collecting standard-sized whole-segment soil samples, and whose soil column is not prone to collapse. This device solves the problems in existing technologies, such as the inability to collect complete whole-segment samples, which leads to the failure of whole-segment soil sample collection, and the easy damage or collapse of the pre-excavated profile.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A soil sampling device for a whole section of soil during a soil survey, comprising:

[0008] A stainless steel frame, wherein support rods are fixedly connected to the inner sides of both the upper and lower ends of the stainless steel frame by welding, and a push-unloading component is installed between the two support rods.

[0009] A baffle is located inside the stainless steel frame and behind the support rod. A cutting part is welded and fixed to the rear end of the stainless steel frame. A separation component is provided on the left rear side of the stainless steel frame. A negative magnetic strip is embedded and fixed to the left inner wall of the stainless steel frame.

[0010] In a preferred embodiment, the soil sample collection device further includes two frame handles respectively welded to the left and right side walls of the front center of the stainless steel frame.

[0011] In a preferred embodiment, the length, width, and height of the stainless steel frame are 21.5cm, 5cm, and 100cm, respectively.

[0012] In a preferred embodiment, the push-unloading assembly includes a fixed rod, a first push rod, a support spring, and a second push rod. The fixed rod has first push rods on both the upper and lower sides of its front end, and the other end of the first push rod is located inside the second push rod. The second push rod also has a support spring installed inside it.

[0013] In a preferred embodiment, the rear end of the fixing rod is welded and fixed to the baffle, the ends of the two first push rods that are close to each other are hinged to the fixing rod, and the first push rod and the second push rod are slidably connected.

[0014] In a preferred embodiment, the two ends of the support spring are fixedly connected to the first push rod and the second push rod, respectively, and the two second push rods are hinged to the two support rods at opposite ends.

[0015] In a preferred embodiment, the thickness of the cut portion decreases in the direction away from the stainless steel frame.

[0016] In a preferred embodiment, the separation assembly includes a cutting plate, a positive magnetic strip, a protruding post, and a handle. The cutting plate is located inside the rear end of the stainless steel frame. The positive magnetic strip is inlaid on the outer wall of the cutting plate. Protruding posts are welded to both the front and rear ends of the top of the cutting plate, and a handle is welded to the top of the rear protruding post.

[0017] In a preferred embodiment, the tops of both protrusions extend into an "L"-shaped guide groove at the top of the stainless steel frame.

[0018] In the solution of the present invention:

[0019] The cutting section allows for easy and effortless vertical insertion of the stainless steel frame into the soil profile. By pulling the handle to the right, two protruding pillars can be moved along the "L"-shaped guide groove at the top of the stainless steel frame. This allows the cutting plate to first rotate and become parallel to the baffle before moving steadily to the right. This enables the separation and cutting of the entire soil sample from the soil, facilitating sample detachment and ensuring that the entire soil sample is collected in one operation. The operation is simple.

[0020] By simultaneously squeezing the two second push rods, the first push rod gradually contracts towards the inside of the second push rod, pushing the fixing rod to drive the baffle to move slowly inside the stainless steel frame, thus stably pushing out the entire soil sample and solving the problem of deformation or collapse during sample removal.

[0031] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0032] like Figure 1-7 As shown, the soil sampling device for a whole section of soil survey of the present invention includes:

[0033] Stainless steel frame 1, with support rods 3 fixedly connected to the inner sides of both the upper and lower ends of stainless steel frame 1 by welding, and a push unloading component 4 installed between the two support rods 3.

[0034] Baffle 5 is located inside the stainless steel frame 1 and behind the support rod 3. A cutting part 6 is welded and fixed to the rear end of the stainless steel frame 1. A separation component 7 is provided on the left rear side of the stainless steel frame 1. A negative magnetic strip 8 is embedded and fixed to the left inner wall of the stainless steel frame 1.

[0035] As a preferred embodiment, based on the above structure, the soil sample collection device further includes two frame handles 2 respectively welded to the left and right side walls of the front middle part of the stainless steel frame 1.

[0036] The frame handle 2 makes it easy to carry and hold the data collection device.

[0037] As a preferred embodiment, based on the above structure, the length, width and height of the stainless steel frame 1 are 21.5cm, 5cm and 100cm respectively.

[0038] By limiting the size of the stainless steel frame, it is easy to cut a complete soil sample that meets the requirements.

[0039] In a preferred embodiment, based on the above structure, the sample unloading assembly 4 further includes a fixed rod 41, a first push rod 42, a support spring 43, and a second push rod 44. The fixed rod 41 has a first push rod 42 on both the upper and lower sides of its front end, and the other end of the first push rod 42 is located inside the second push rod 44. The support spring 43 is also installed inside the second push rod 44. By squeezing the second push rod 44, the first push rod 42 rotates while the two gradually contract, which facilitates applying pressure to the fixed rod 41 and controls the fixed rod 41 to move the baffle 5 backward, so as to facilitate the separation of the sample from the stainless steel frame 1.

[0040] In a preferred embodiment, based on the above structure, the rear end of the fixing rod 41 is welded and fixed to the baffle 5, the ends of the two first push rods 42 that are close to each other are hinged to the fixing rod 41, and the first push rod 42 and the second push rod 44 are slidably connected.

[0041] By using two first push rods 42 and two second push rods 44 symmetrically arranged above and below the fixing rod 41, the sliding stability of the fixing rod 41 and the baffle 5 can be improved, making it easier for the baffle 5 to move back stably and avoiding damage to the entire soil sample.

[0042] As a preferred embodiment, based on the above structure, the two ends of the support spring 43 are fixedly connected to the first push rod 42 and the second push rod 44 respectively, and the two second push rods 44 are hinged to the two support rods 3 respectively at their opposite ends.

[0043] The support spring 43 facilitates the restoration of the first push rod 42 and the second push rod 44.

[0044] As a preferred embodiment, based on the above structure, the thickness of the cutting portion 6 is further set to decrease in the direction away from the stainless steel frame 1.

[0045] By using the cutting section 6 with decreasing thickness, the resistance encountered by the stainless steel frame 1 during the whole-section sampling process of inserting it into the soil can be reduced, achieving a more convenient, faster, and more labor-saving effect.

[0046] As a preferred embodiment, based on the above structure, the separation component 7 further includes a cutting plate 71, a positive magnetic strip 72, a protrusion 73 and a handle 74. The cutting plate 71 is located on the inner side of the rear end of the stainless steel frame 1. The positive magnetic strip 72 is inlaid on the outer wall of the cutting plate 71. The protrusion 73 is welded to both the front and rear ends of the top of the cutting plate 71. The handle 74 is welded to the top of the rear protrusion 73.

[0047] When the handle 74 is pulled, the protruding post 73 in the transverse guide groove at the top of the stainless steel frame 1 moves to the right, while the protruding post 73 in the longitudinal guide groove moves steadily backward. At this time, the cutting plate 71 gradually rotates. When both protruding posts 73 are in the transverse guide groove, the cutting plate 71 is in a state parallel to the baffle 5. At this time, the cutting plate 71 is controlled to move to the right, which can separate and cut the entire section of soil sample from the soil, making it easier for the soil sample to be removed.

[0048] As a preferred embodiment, based on the above structure, the top of each of the protruding pillars 73 extends into the "L"-shaped guide groove opened at the top of the stainless steel frame 1.

[0049] The L-shaped guide groove on the top of the stainless steel frame 1 facilitates the control of the separation component 7 to move along the set direction. During sampling, the cutting plate 71 can be attached to the side wall of the stainless steel frame 1 using the positive magnetic strip 72 and the negative magnetic strip 8, thus achieving concealed storage of the cutting plate 71 and avoiding interference with soil sampling.

[0050] The working principle of this invention is as follows:

[0051] When using it, first hold the two frame handles 2 on the left and right sides, and push the stainless steel frame 1 vertically into the pre-excavated soil profile, such as... Figure 7As shown, the cutting section 6, whose thickness decreases with distance from the stainless steel frame 1, facilitates easier and less strenuous insertion of the stainless steel frame 1. Then, the handle 74 is manually moved to the right. At this time, the protrusion 73 located behind the top of the cutting plate 71 moves to the right along the transverse guide groove at the top of the stainless steel frame 1, while the other protrusion 73 moves backward in the longitudinal guide groove. During this process, the cutting plate 71 gradually rotates. When both protrusions 73 are in the transverse guide groove, the cutting plate 71 is parallel to the baffle 5. At this time, the cutting plate 71 is moved to the right by the handle 74, which can cut the soil, facilitate the separation of soil sample from land, and ensure that the entire soil sample is collected in one go. The operation is simple.

[0052] When the entire soil sample is removed from the stainless steel frame 1, the two second push rods 44 can be pressed at the same time. At this time, the second push rods 44 drive the first push rod 42 to rotate synchronously and both gradually retract, which can push the fixing rod 41 to drive the baffle 5 to move steadily and slowly backward inside the stainless steel frame 1, making it easy to push the entire soil sample out stably. The entire soil sample is not easily damaged, which solves the problem of deformation or collapse during the sample removal process, making it easy to collect the complete sample and with a high sampling success rate.

[0053] It should be noted that during the sampling process, such as Figure 4 As shown, the cutting plate 71 is concealed in the inner left wall of the stainless steel frame 1, and the separation component 7 can be positioned by adsorption by the mutual attraction of the positive magnetic strip 72 and the negative magnetic strip 8, so as to avoid interfering with soil sampling.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of the present invention and on the basis of the prior art through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
