Description

Technical Field

[0001] The utility model relates to the technical field of soil collection, in particular to a handheld soil collection device. Background Art

[0002] Soil sampling refers to the method of collecting soil samples, including the layout and sampling techniques. Cross-section soil sampling should be conducted after the cross-section observations and records are completed. Before sampling, the cross-section should be trimmed and cleaned, and the top layer of loose soil should be removed. Samples should then be collected layer by layer from the central, representative area, from top to bottom.

[0003] The existing sampling method usually uses a digging tool such as a shovel to dig out a part of the soil sample and pour it into a sample bottle for sealing. This method is simple and easy to use. However, in actual use, it is sometimes necessary to extract soil samples from deeper locations. At this time, it is necessary to dig deeper and repeatedly repair and clean the sampling site, and then use a digging tool such as a shovel to take samples again. The process is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a handheld soil sampling device, which solves the problem that when digging soil samples at different locations, repeated digging, renovation and cleaning of the sampling site are required, which is tedious, time-consuming and labor-intensive.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a handheld soil collection device, including a collection tube and a tube cap, wherein the upper and lower ends of the tube cap are respectively provided with an upper fixing ring and a lower fixing ring, and the outer walls of the upper fixing ring and the lower fixing ring are provided with external threads, a center hole is opened inside the tube cap, and a sampling rod is screwed together with the center hole and the interior of the lower fixing ring, a soil sampling mechanism is provided inside the sampling rod, and a sampling head is provided at the lower end of the sampling rod.

[0006] Preferably, the soil sampling mechanism includes a vertical cavity opened in the sampling rod, a push rod is movably inserted in the vertical cavity, the upper and lower ends of the push rod are respectively provided with a handle and a sphere, the lower end of the vertical cavity is connected to the sampling head, and a spring is installed between the upper wall surface of the sampling rod and the lower wall surface of the handle, and the spring is sleeved on the outside of the push rod.

[0007] Preferably, the sampling head is a cylindrical structure with an arc-shaped tip at the lower end, a sampling groove is opened on one side of the sampling head, and the outer diameter of the sampling head is larger than the outer diameter of the sampling rod.

[0008] Preferably, a circular ring is fixedly mounted on the inner wall of the upper end of the collection tube, and the lower fixed ring is screwed into the circular ring.

[0009] Beneficial effects

[0010] Inside the collection tube are provided a collection rod and a sampling head. The sampling head is a tubular structure with an arc-shaped tip and a sampling slot. When sampling soil, the sampling head can be used as a shovel, or it can be inserted into deeper soil. At this time, the interior of the sampling head will be filled with soil, making it easier to sample. By pressing the handle, the push rod can drive the ball into the sampling head to push the soil out. If the sampling location is deeper, the tube cap and the lower fixing ring can be unscrewed and the upper fixing ring can be screwed into the ring, so that the collection tube and the collection rod are connected as one, increasing the overall length. The collection tube, collection rod and sampling head are designed together for easy portability. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figure 1-2 , a handheld soil collection device, including a collection tube 1 and a tube cap 4, the upper and lower ends of the tube cap 4 are respectively provided with an upper fixing ring 5 and a lower fixing ring 3, the outer walls of the upper fixing ring 5 and the lower fixing ring 3 are provided with external threads, a center hole is opened inside the tube cap 4, the center hole and the interior of the lower fixing ring 3 are screwed with a sampling rod 2, a soil sampling mechanism is provided in the sampling rod 2, and a sampling head 10 is provided at the lower end of the sampling rod 2;

[0016] The upper fixing ring 5 and the lower fixing ring 3 have the same structure. The sampling rod 2 can be screwed into the lower fixing ring 3 and the tube cap 4 or into the upper fixing ring 5 and the tube cap 4. A fixed annular node is provided on the outer wall of the sampling rod 2, which is used to be clamped on the outer walls of the upper fixing ring 5 and the lower fixing ring 3 to prevent the sampling rod 2 from being screwed too deep.

[0018] Pressing the handle 6 causes the push rod 7 to drive the ball 12 into the sampling head 10 , thereby pushing the soil in the sampling head 10 into the collection tube 1 .

[0019] Furthermore, the sampling head 10 is a cylindrical structure with an arc-shaped tip 11 at the lower end. A sampling slot 13 is opened on one side of the sampling head 10 . The outer diameter of the sampling head 10 is larger than the outer diameter of the sampling rod 2 .

[0020] Furthermore, a circular ring 9 is fixedly mounted on the inner wall of the upper end of the collection tube 1 , and the lower fixing ring 3 is screwed into the circular ring 9 .

[0021] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0022] Embodiment: When in use, first screw the tube cap 4 to separate the lower fixing ring 3 from the circular ring 9, then unscrew the sampling rod 2 from the tube cap 4 and the lower fixing ring 3, insert the sampling head 10 into the soil through the sampling rod 2 and then take it out. At this time, the inside of the sampling head 10 will be filled with soil, and then put the taken out soil into the collection tube 1. Finally, put the sampling rod 2 back into the tube cap 4 and the lower fixing ring 3, and screw the tube cap 4 onto the collection tube 1. When it is necessary to take soil from a deeper position, unscrew the tube cap 4 from the collection tube 1, and then screw the upper fixing ring 5 into the circular ring 9 upside down, so that the collection tube 1 becomes an extension handle of the sampling rod 2, which is easy to use.
