Description

Technical Field

[0001] The utility model relates to a soil sampling tool, belonging to the field of soil detection. Background Art

[0002] During the soil detection process, it is necessary to sample the soil. When sampling the bottom soil, a cylinder is often used for sampling. A rubber plug is slidably installed in the cylinder, and a pull rod installed at one end of the rubber plug extends to the outside of the cylinder, so that the open end of the cylinder passes through the water body and is inserted into the bottom soil. Because the contact part between the bottom soil and the water body is relatively loose, after the cylinder is inserted into the soil, the loose layer on the surface of the bottom soil will enter the cylinder, and some water will also enter the cylinder. That is, the soil sample entering the cylinder will slide out of the cylinder due to insufficient hardness, resulting in sampling failure. Therefore, it is necessary to design a soil sampling tool that can improve the success rate of collecting bottom soil. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a soil sampling tool to solve the problems raised in the above-mentioned background technology. The present invention can collect soil below the loose layer of soil at the bottom of the water, thereby improving the success rate of collecting soil at the bottom of the water.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a soil sampling tool, including a water-blocking cylinder, one end of which is hinged with two conical tips that can form a conical body structure, and the inner walls of the two conical tips are equipped with magnet blocks that attract each other, and the end of the water-blocking cylinder away from the conical tip is equipped with a round cover, one side of the round cover is provided with a threaded hole that penetrates the round cover, and a tube for pushing open the two conical tips is threadedly connected in the threaded hole, and the outer surface of the upper end of the tube is processed with an external thread, and the end of the tube close to the conical tip is open, and a sampling tube for storing soil samples is slidably installed in the tube, and the end of the sampling tube close to the conical tip is open, and a guide hole is provided on the side of the tube away from the conical tip, and a hollow tube is inserted in the guide hole, and the end of the hollow tube in the tube is connected and fixed to the sampling tube and communicates, and the end of the hollow tube on the outside of the tube is threadedly connected with a sealing cover.

[0005] Furthermore, a rubber ring is connected and fixed to the upper position inside the water-blocking tube, the rubber ring is sleeved on the tube, and the rubber ring is located at the lower side of the external thread.

[0006] Furthermore, a rubber plug is fixedly connected to one end of the sampling tube away from the conical tip. The rubber plug is sleeved on the hollow tube and is in sliding contact with the hollow tube. The outer surface of the rubber plug is in sliding contact with the inner wall of the tube.

[0007] Furthermore, one end of the water stop away from the conical tip is sleeved with a connecting ring connected and fixed to the water stop, and the round cover is connected and fixed to the connecting ring by a plurality of connecting screws.

[0008] Furthermore, a limiting ring connected and fixed to the hollow tube is sleeved on one end of the hollow tube close to the sealing cover, and the outer diameter of the limiting ring is larger than the inner diameter of the guide hole.

[0009] Furthermore, the outer surface of one end of the hollow tube away from the sampling tube is processed with an external thread, the inner surface of the sealing cover is processed with an internal thread matching the external thread, and a sealing ring connected to the end of the hollow tube is provided in the sealing cover.

[0010] Furthermore, a handle is fixedly connected to one end of the barrel located outside the watertight barrel, and the handle is arranged perpendicular to the barrel.

[0011] Beneficial effects of the utility model:

[0012] 1. When sampling the bottom soil, make the two conical tips installed at the lower end of the watertight tube pass through the loose layer of the bottom soil, so that the lower end of the watertight tube is in the soil layer with higher hardness on the bottom of the water, and then rotate the tube to move the tube downward. At this time, the tube pushes open the two conical tips, removes the sealing cover and presses the hollow tube downward. At this time, the hollow tube drives the sampling tube to move downward and is inserted into the soil with higher hardness on the bottom of the water. Then, a part of the soil with higher hardness on the bottom of the water will enter the sampling tube. Under the pressure of the soil, the air in the sampling tube is discharged through the hollow tube, so as to collect the soil below the loose layer of the bottom soil, prevent the soil from slipping during the collection of the bottom soil, and improve the success rate of collecting the bottom soil.

[0013] 2. Install a rubber ring in the water-blocking tube and put it on the tube. At this time, the external thread on the tube is between the rubber ring and the round cover to prevent debris in the water from adhering to the part of the tube where the external thread is processed.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figure 1 and Figure 2 The utility model provides a technical solution: a soil sampling tool, including a watertight shell 1, one end of which is hinged with two conical tips 2 that can form a conical structure, and the inner walls of the two conical tips 2 are installed with mutually attractive magnet blocks 10. Under the action of the mutual attraction of the two magnet blocks 10, the two conical tips 2 are fitted together. At this time, a sealing strip connected and fixed to one conical tip 2 is located between the fitting parts of the two conical tips 2, thereby improving the sealing between the two conical tips 2. At the same time, a sealing strip is also provided at the contact part between the conical tip 2 and the watertight shell 1, thereby improving the sealing between the conical tip 2 and the watertight shell 1.

The threaded hole 13 penetrating the round cover 3 opened on one side of the round cover 3 is internally threadedly connected with a tube 8 for pushing open the two conical tips 2, wherein the outer surface of the upper end of the tube 8 is processed with an external thread, and the end close to the conical tip 2 is an open tube 8 in which a sampling tube 9 for storing soil samples is slidably installed, and the end of the sampling tube 9 close to the conical tip 2 is The tube 8 is in an open shape, and a hollow tube 7 is inserted into a guide hole opened on one side of the tube 8 away from the conical tip 2, wherein one end of the hollow tube 7 in the tube 8 is connected and fixed to the sampling tube 9 and communicates with each other, and the outer surface of the end of the hollow tube 7 outside the tube 8 is processed with an external thread, and the inner surface of the sealing cover 6 with an internal thread is threadedly connected to the hollow tube 7, wherein a sealing ring is installed in the sealing cover 6 at the connection with the end of the hollow tube 7, and when sampling the bottom soil, the two conical tips 2 installed at the lower end of the watertight tube 1 pass through the bottom mud. The lower end of the water-blocking tube 1 is placed in the soil layer with greater hardness at the bottom of the water, and then the tube 8 is rotated to move the tube 8 downward. At this time, the tube 8 pushes open the two conical tips 2, removes the sealing cover 6 and presses the hollow tube 7 downward. At this time, the hollow tube 7 drives the sampling tube 9 to move downward and is inserted into the soil with greater hardness at the bottom of the water. Then, a part of the soil with greater hardness at the bottom of the water will enter the sampling tube 9. Under the pressure of the soil, the air in the sampling tube 9 is discharged through the hollow tube 7, so that the water below the loose layer of soil at the bottom of the water can be collected. To prevent the soil from slipping during the collection of underwater soil and improve the success rate of collecting underwater soil, one end of the barrel 8 on the outside of the water-blocking barrel 1 is connected and fixed with a handle 4 arranged vertically to the barrel 8, and the handle 4 provides a gripping carrier for rotating the barrel 8, and one end of the hollow tube 7 close to the sealing cover 6 is provided with a limiting ring 5 connected and fixed to the hollow tube 7, wherein the outer diameter of the limiting ring 5 is larger than the inner diameter of the guide hole, and under the restriction of the limiting ring 5, the hollow tube 7 is prevented from falling into the barrel 8 after the sealing cover 6 is removed.

At the same time, the rubber ring 11 is on the lower side of the external thread. The rubber ring 11 is installed in the watertight tube 1 and sleeved on the barrel 8. At this time, the external thread processed on the barrel 8 is between the rubber ring 11 and the round cover 3, which prevents debris in the water from arbitrarily adhering to the part of the barrel 8 where the external thread is processed, so that the end of the sampling barrel 9 away from the conical tip 2 is connected and fixed with a rubber plug 12. The rubber plug 12 is sleeved on the hollow tube 7 and in sliding contact with the hollow tube 7, wherein the outer surface of the rubber plug 12 is in sliding contact with the inner wall of the barrel 8. Under the action of the rubber plug 12, the movement resistance of the sampling barrel 9 is increased.
