Description

Technical Field

[0001] The utility model relates to the technical field of land resource detection, in particular to a land resource sampling device. Background Art

[0002] Land resources refer to land that can be used for agriculture, forestry, animal husbandry or other purposes. They are the basic materials for human survival and the object of labor, and have both qualitative and quantitative contents. During their utilization, different types and degrees of transformation measures may need to be taken. Land is extremely important to humans, so sampling and testing of soil is also essential.

[0003] For example, a soil sampling device for land resource detection is disclosed in a Chinese utility model patent with a publication number of CN216082129U. Although the above-mentioned prior art can smoothly take out the sample by providing a detachable drill bit at the lower end of the drill rod, and the sampling device has a simple structure, it is necessary to drill multiple sampling holes when sampling at different depths in the same place, which wastes time and affects work efficiency. In addition, the sampling holes are formed by squeezing the soil around, which will result in no excess soil to fill the sampling holes after the sampling is completed. The unfilled sampling holes are exposed to the air, which will cause the organic matter in the soil to oxidize, resulting in a waste of resources. Utility Model Content

[0004] In order to solve the technical problem that when sampling at different depths in the same place, it is necessary to drill multiple sampling holes, which wastes time and affects work efficiency, and the sampling holes are formed by squeezing soil to the surroundings, which will result in no excess soil to backfill the sampling holes after the sampling is completed, and the unfilled sampling holes are exposed to the air, which will cause oxidation of organic matter in the soil and cause waste of resources, the utility model provides a land resource sampling device.

[0011] As a further improvement of the above scheme, the connecting assembly includes a threaded block arranged on one side of the connecting plate and fixedly installed with the connecting plate, and a fixed block arranged on one end of the threaded column and fixedly installed with the threaded column, and a threaded groove cooperating with the thread of the threaded column is opened on one side of the fixing block.

[0012] Through the above technical solution, when the sampling component cannot meet the sampling requirements, the sampling component can be replaced.

[0013] As a further improvement of the above scheme, a plurality of first fixing grooves are provided on one side of the left sampling half tube, and a plurality of second fixing grooves are provided on one side of the left sampling half tube, wherein one of the fixing components includes a limiting plate rotatably installed on one side of the first fixing groove and extending to the adjacent second fixing groove, and a round-head limiting column fixedly installed in each second fixing groove, and a limiting hole matched with the round-head limiting column is provided on one side of the limiting plate.

[0014] Through the above technical solution, the sampling component is prevented from opening by itself when the sampling component is inserted into the soil.

[0015] As a further improvement of the above solution, a support plate is fixedly mounted on one end of the support column, and a sampling hole adapted to the sampling assembly is opened on one side of the support plate.

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Please combine Figure 1-Figure 4 A land resource sampling device of this embodiment includes a support column 1, a left sampling half-tube 201 is provided on one side of the support column 1, a right sampling half-tube 202 is provided on one side of the left sampling half-tube 201, a rotating shaft 6 rotatably mounted on one side of the left sampling half-tube 201 and rotatably mounted with the right sampling half-tube 202, a connecting plate 7 is rotatably mounted on one end of the rotating shaft 6, one side of the connecting plate 7 is fitted with the same end of the left sampling half-tube 201 and the right sampling half-tube 202, and the two sampling half-tubes can be combined and opened, so as to facilitate sampling of soil columns at different depths.

[0027] Combination Figure 1 and Figure 2 A mounting plate 8 is fixedly installed on one side of the support column 1, and a threaded cylinder 301 is fixedly installed on one side of the mounting plate 8. A threaded column 302 that is threadedly matched with the threaded cylinder 301 is provided inside the threaded cylinder 301, and a sliding groove is opened at one end of the threaded column 302. A servo motor 9 is installed on one side of the mounting plate 8, and a connecting rod with one end passing through the mounting plate 8 is fixedly installed on the output end of the servo motor 9, and a sliding bar 10 with one end passing through the threaded cylinder 301 and extending into the sliding groove and slidingly matched with the threaded column 302 is fixedly installed on one end of the connecting rod. The servo motor 9 drives the threaded column 302 to rotate, thereby pushing the sampling assembly to take soil samples.

[0028] Combination Figure 1-Figure 3 A threaded block 401 is fixedly installed on one side of the connecting plate 7, a fixed block 402 is fixedly installed on one end of the threaded column 302, and a threaded groove that matches the threaded column 302 is opened on one side of the fixed block 402. When the sampling component cannot meet the sampling requirements, the sampling component can be replaced.

[0029] Combination Figure 1-Figure 4 A plurality of first fixing grooves are provided on one side of the left sampling half tube 201, and a plurality of second fixing grooves are provided on one side of the right sampling half tube 202. A limiting plate 501 is rotatably installed inside the first fixing groove, and one side of the limiting plate 501 extends to the adjacent second fixing groove. A round-head limiting column 502 is fixedly installed inside the second fixing groove. A limiting hole matched with the round-head limiting column 502 is provided on one side of the limiting plate 501 to prevent the sampling assembly from opening by itself when the sampling assembly is inserted into the soil.

[0030] Combination Figure 1 A support plate 11 is fixedly mounted on one end of the support column 1, and a sampling hole adapted to the sampling component is opened on one side of the support plate 11. The support plate 11 provides a supporting effect during the sampling process.

[0031] The implementation principle of a land resource sampling device in the embodiment of the present application is as follows: when sampling the land, the left sampling half tube 201 and the right sampling half tube 202 are closed, and the left sampling half tube 201 and the right sampling half tube 202 are completely fixed and locked by using the limiting plate 501 and the round-head limiting column 502. The sampling assembly is fixed on the threaded column 302 through the threaded block 401 on the connecting plate 7, and the servo motor 9 is started. The rotation of the servo motor 9 will drive the threaded column 302 to rotate, and the threaded barrel 301 is fixed, so the threaded column 302 will push the sampling assembly to rotate and move downward. , so that the sampling component can rotate during the downward movement, which is convenient for sampling the soil. Because the sampling component cannot penetrate into the soil by simply descending, when the soil is taken out by the sampling component, the fixed cooperation between the limit plate 501 and the round-head limit column 502 is released, and the left sampling half pipe 201 is rotated to open the sampling component to expose the entire soil column. The soil column can be sampled at different depths according to the required depth. In this way, multiple samplings at different depths can be completed in one soil sampling. When the sampling is completed, the soil column can be put back into the sampling hole drilled on the ground to complete the backfilling of the sampling hole.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
