Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soil science, in particular to a single-point three-sample bulk density collection device for the surface layer of a ground matrix. Background Art
[0002] In the research field of soil science and agricultural science, the physical property index of soil bulk density is of vital importance. It defines the dry weight of a unit volume of soil in its natural state. It not only reveals the texture and structural conditions of the soil, but also serves as a key reference for evaluating the content of soil organic matter. Especially in the current research on surface matrix, accurate determination of soil bulk density plays an irreplaceable role in describing the physical properties of surface soil. The existing mainstream determination method is the knife ring method, which is to vertically insert a knife ring of a specific volume into the undisturbed soil, take out the knife ring filled with soil, dry it, and weigh it, so as to calculate the bulk density of the soil. However, this method has limitations in actual operation: only one sample can be collected at a time, which is not efficient; moreover, each insertion of the knife ring will cause compression on the surrounding soil, affecting the accuracy of the data. Although there are a variety of soil sampling equipment on the market, none of them can meet the demand of collecting multiple bulk density samples at the same time. Utility Model Content
[0003] The purpose of the utility model is to provide a single-point three-sample bulk density collection device for the surface layer of a surface matrix, which solves the problem in the prior art that although there are a variety of sampling devices for collecting surface matrix bulk density on the market, it is still impossible to complete the collection of multiple bulk density samples at the same time.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Preferably, the handle is provided with a grip for applying force, and the bottom of the handle is fixedly connected to the linkage tripod frame by a buckle.
[0007] Preferably, a connecting ring is provided in the middle of the adjustable bracket, a retractable support rod is provided at the lower part, and a fixed base is provided at the bottom of the retractable support rod, so that the height of the bracket can be adjusted according to the flatness of the ground surface.
[0008] Preferably, the linked three-pronged frame is welded into a whole by an upper straight rod and three lower oblique rods, and connectors are welded at the bottom ends of the three oblique rods for connecting the bulk density sampler.
[0009] Preferably, the bulk density sampler is composed of two mutually symmetrical semicircular tubes, the side walls of the semicircular tubes are provided with slots and plugs, and the middle of the bulk density sampler is provided with a groove for placing a ring knife.
[0010] Preferably, the connection between the components in the device is mainly threaded connection and slot insertion.

[0012] The utility model has at least the following beneficial effects:
[0013] In order to overcome the shortcomings of the existing technology, we proposed an innovative single-point three-sample bulk density collection device for the surface layer of the surface matrix. This device can collect bulk density samples of three surface layers at the same time, and is particularly suitable for collecting soil with high compaction. The device is exquisitely designed and consists of three major parts: a transmission device, an adjustable bracket, and a bulk density sampler. The transmission device is equipped with a handle, which allows the operator to apply greater force by rotating and easily complete the collection task. The telescopic function of the adjustable bracket enables the device to flexibly adjust the height according to the flatness of different surfaces, ensuring that the depth of the soil collected each time is consistent, thereby greatly reducing the error caused by depth differences. The bulk density sampler is designed to be detachable, which makes it easy to remove the ring knife and soil samples as a whole, ensuring the integrity of the sample. In addition, the gap spacing design inside the ring knife sampler effectively reduces the deformation of the soil caused by extrusion during the collection process, further improving the accuracy of the data. In the entire device, the components are connected by stable threads and slots to ensure stability and sealing in use. This innovative device not only improves the sampling efficiency, but also significantly improves the accuracy of data collection. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0020] Reference Figure 1-3 A single-point three-sample bulk density collection device for the surface layer of a surface matrix comprises a handle 1, a linked three-pronged frame 2, an adjustable bracket 3 and a bulk density sampler 4. The handle 1 is connected to the linked three-pronged frame 2 via a buckle 5, the bulk density sampler 4 is connected to the linked three-pronged frame 2 via a connector 11, and the adjustable bracket 3 is connected to the linked three-pronged frame 2 via a connecting ring 9, so that the device can collect three surface bulk density samples at the same time.
[0021] The single-point three-sample bulk density collection device for the surface layer of the local surface matrix has achieved efficient and accurate surface matrix bulk density sampling through sophisticated design. Its main beneficial effects are reflected in: First, the device can collect bulk density samples of three surface layers at the same time, which significantly improves the sampling efficiency and reduces the workload and time cost. Secondly, the design of the adjustable bracket enables the device to flexibly adapt to different surface flatness, ensuring the consistent depth of the collected soil, thereby reducing the error caused by the depth difference and improving the accuracy and reliability of the data. Furthermore, the special design of the bulk density sampler, such as the groove and detachable structure, not only facilitates the placement and removal of the ring knife, but also ensures the integrity of the sample, further improving the accuracy of the sampling. Finally, the various components of the device are connected by stable threads and slots to ensure the stability and durability of the device during use. In summary, the device has brought great convenience and benefits to the surface matrix bulk density sampling work through innovative design and structural optimization.
[0022] Furthermore, the handle 1 is provided with a grip 6 for applying a force, and the bottom of the handle 1 is fixedly connected to the linkage tripod frame 2 via a buckle 5 .
[0023] Furthermore, a connecting ring 9 is provided in the middle of the adjustable bracket 3, a retractable support rod 14 is provided at the lower part, and a fixed base 15 is provided at the bottom of the retractable support rod 14, so that the height of the bracket can be adjusted according to the flatness of the ground surface.
[0024] Furthermore, the linked three-pronged frame 2 is welded into a whole by an upper straight rod 7 and three lower oblique rods 10 , and connectors 11 are welded at the bottom ends of the three oblique rods for connecting the bulk density sampler 4 .
[0025] Furthermore, the bulk density sampler 4 is composed of two mutually symmetrical semicircular tubes, the side walls of the semicircular tubes are provided with slots 18 and plugs 21, and the middle of the bulk density sampler 4 is provided with a groove 17 for placing a ring knife.
[0026] Furthermore, the connection between the components in the device is mainly threaded connection and slot insertion. This connection method can ensure the stability between the components and the sealing of the connection, thereby improving the reliability and durability of the device during use.
[0027] Furthermore, its design feature is that it can collect three surface bulk density samples simultaneously, which significantly improves the sampling efficiency and ensures the high accuracy of data collection. It is suitable for soil environments with high compaction and provides a convenient and efficient collection tool for related research and applications.
[0028] The utility model discloses a surface matrix surface layer single-point three-sample bulk density collection device, which can collect three bulk density samples at the investigation point at the same time. Each time it is used, it is necessary to ensure that all parts are tightly connected. When starting the operation, a downward force is applied to the handle 1 to open the buckle of the connecting ring 9 in the adjustable bracket 4, drive the linked three-pronged bracket 2 to move downward, and transmit the force to the bulk density sampler 4, so that the bulk density sampler 4 is vertically inserted into the soil layer. When the bulk density sampler 4 is completely inserted into the soil layer, the downward force is stopped, and an upward force is applied instead to bring the bulk density sampler 4 out of the soil layer; after the bulk density sampler 4 completely leaves the soil layer, the bulk density sampler 4 is disconnected from the connector 11 and the drill bit 12 by rotating the thread, and then the two semicircular tubes are separated, and the built-in ring cutter is taken out. Because there is a gap inside the bulk density sampler 4, a part of the excess soil sample will be retained when the ring cutter is taken out, and the excess soil is removed by a scraper to obtain a complete bulk density sample, and the subsequent bulk density drying and weighing work is completed.
