Description

Technical Field

[0001] This utility model relates to the field of soil sample collection technology, and in particular to a portable multifunctional soil sample collection device. Background Technology

[0002] Soil bulk density: Soil bulk density should be called dry bulk density, also known as soil pseudo density, which refers to the ratio of the mass of a certain volume of soil (including soil particles and interparticle pores) after drying to its volume before drying; Soil porosity: This is the percentage of soil pore volume to soil volume. Various shapes and sizes of soil particles aggregate and arrange to form a solid phase skeleton. The skeleton contains pores of different widths and shapes, forming a complex pore system. The percentage of the total pore volume to the soil volume is called soil porosity; Water and air coexist and fill the soil pore system.

[0003] During sampling, a soil ring cutter is typically used to collect undisturbed soil samples. It is a common experimental tool for experiments such as shearing, bulk density, compression, and permeability testing. It is generally made of copper or stainless steel, offering good corrosion resistance and meeting high mechanical strength requirements. For example, Chinese Patent Publication No. CN218725467U discloses a "soil sample collector," which consists of a positioning sleeve, a central rod, a counterweight sleeve, and a shovel. In use, the ring cutter is located at the bottom of the positioning sleeve, the central rod is fixed to the top of the positioning sleeve, the counterweight sleeve is fitted onto the central rod, and the shovel is located in a receiving groove at the top of the central rod. To collect soil samples, the shovel is removed from the central rod, the ground is cleaned, the ring cutter is inserted into the soil, the positioning sleeve is placed on top of the ring cutter, and the counterweight sleeve is used to strike the positioning sleeve, thus driving the ring cutter into the ground. The soil around the ring cutter is then removed using the shovel, and the ring cutter is removed from the soil. After removal, the surface and both ends of the ring cutter are cleaned to complete the soil sample collection.

[0004] However, in actual use, due to the variety of equipment carried in outdoor operations, the counterweight of the data collector increases the burden on the user when carried. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the increased burden on users due to the weight of the sampler's counterweight, and to propose a portable, multifunctional soil sample collection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A portable multifunctional soil sample collection device is designed, including a base and a ring cutter. The base has a mounting groove, and the ring cutter is disposed in the mounting groove. A pressing part is connected to the upper end of the base. The pressing part is movably inserted into the mounting groove and in contact with the ring cutter. A positioning rod is provided on the pressing part, and a force-applying component is movably inserted into the positioning rod. The lower end of the force-applying component contacts the pressing part. An anchor point is provided on the base.

[0007] Furthermore, the pressing part is integrally formed with a force-receiving plate that cooperates with the force-applying component, and the force-receiving plate is threadedly connected to the positioning rod.

[0008] Furthermore, the positioning rod includes multiple rod bodies, and each end of the rod body is provided with a threaded portion and a threaded hole.

[0009] Furthermore, the force-applying component has a receiving groove inside, and a sealing cap is threadedly connected to the force-applying component.

[0010] Furthermore, a digging blade is provided at the lower end of the base, and a screw is fixedly provided on the anchor point. The screw passes through the digging blade and is threadedly connected to the base.

[0011] Furthermore, the lower end of the base is provided with a groove that mates with the digging blade, the digging blade is installed in the groove, and the groove is provided with a screw hole that mates with the screw rod.

[0012] The portable, multifunctional soil sample collection device proposed in this utility model has the following advantages: In this utility model, by setting a base, a ring cutter and a pressing part, the main components are disassembled for easy carrying, avoiding carrying the whole thing and thus reducing the difficulty of carrying. The positioning rod is disassembled into multiple rods, which can be spliced ​​according to needs, which also reduces the difficulty of carrying. Secondly, in this utility model, by providing a receiving groove on the force-applying component, the weight of the force-applying component is reduced. During use, water, stones, or soil can be filled into the receiving groove to increase the force of the force-applying component falling. The receiving groove can also be used to load the ring cutter to prevent the ring cutter from being damaged during transportation. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4 A portable multifunctional soil sample collection device includes a base 1 and a ring cutter 2. The base 1 has a mounting groove 3, and the ring cutter 2 is disposed in the mounting groove 3. The upper end of the base 1 is connected to a pressing part 4. The pressing part 4 is movably inserted into the mounting groove 3 and in contact with the ring cutter 2. A positioning rod 5 is provided on the pressing part 4, and a force-applying member 6 is movably inserted into the positioning rod 5.

[0021] Furthermore, in this embodiment, a digging blade 8 is provided at the lower end of the base 1, and a screw is fixedly provided on the anchor point 7. The screw passes through the digging blade and is threadedly connected to the base 1. By providing the digging blade 8, the surrounding soil can be removed when the ring cutter 2 is sampling. The digging blade 8 can also scrape off excess soil on the ring cutter 2, making the soil surface in the ring cutter 2 flush with the upper edge of the ring cutter 2. When there are plant roots, the digging blade 8 can also cut the plant roots.

[0022] More specifically, in this embodiment, the lower end of the base 1 is provided with a groove 81 that cooperates with the digging blade 8. The digging blade 8 is installed in the groove 81 to prevent the digging blade 8 from injuring people and to prevent the cutting edge of the digging blade 8 from breaking. The groove 81 is provided with a screw hole that cooperates with the screw rod.

[0023] Working method: During operation, the main components are disassembled into a base 1, a ring cutter 2, and a pressing part 4 for easy carrying. The positioning rod 5 is disassembled into multiple rods 51, which can be spliced ​​and adjusted in length according to needs, reducing the difficulty of carrying. By setting a receiving groove 61, the weight of the force-applying component is reduced, making it more portable. When in use, water, stones, or soil can be filled into the receiving groove to increase the force applied to the pressing part 4 when the force-applying component falls. The receiving groove can also be used to load the ring cutter 2 to prevent the ring cutter 2 from being damaged during transportation. The digging blade 8 is installed in the groove 81, and the surrounding soil can be removed when the ring cutter 2 is sampling.
