Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, and more specifically, to a soil sampling device for land improvement. Background Art

[0002] Priority sampling is required when conducting experimental testing on regional soil, and sampling equipment is required to assist in sampling. Existing sampling equipment needs to take out the sample soil and store it separately after completing the sampling. Therefore, when multiple sampling is required, frequent removal of sample soil will greatly reduce the sampling efficiency and make it difficult to take out the sample soil.

[0003] According to the Chinese utility model publication number CN215414465U, a soil sampling device is disclosed, comprising: a sampling cylinder with a plurality of sampling ports provided on the side wall, wherein the plurality of sampling ports are distributed along the axial direction of the sampling cylinder; and a power device, which provides power for the sampling cylinder to extend into the soil. The soil sampling device provided by the present utility model arranges the sampling cylinder in a vertical direction, and utilizes a power device to drive the sampling cylinder to gradually extend into the ground. The plurality of sampling ports provided on the sampling cylinder are respectively located at different depths, and when the sampler is switched to the first position, the sampler can perform a sampling operation. However, this arrangement requires that the sample soil be taken out and stored separately after the sampling is completed. Therefore, when multiple sampling is required, the frequent removal of sample soil will greatly reduce the sampling efficiency, and the sample soil is difficult to remove. Therefore, in view of this problem, how to design a soil sampling device for land reclamation has become a problem that we currently need to solve. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0021] Refer to the instruction manual Figure 1-4 ,like Figure 1 As shown, a soil sampling device for land reclamation according to an embodiment of the present invention comprises a main body 1, a sampling tube 2 is rotatably connected to the interior of the main body 1, a sample storage tube 3 is slidably connected to the inner wall of the sampling tube 2, a cutter head 4 is fixedly installed at the bottom of the sampling tube 2, and the sample storage tube 3 and the cutter head 4 are arranged in a close-fitting manner, as shown in FIG. Figure 2 As shown, the inner wall of the sampling tube 2 is fixedly installed with a limiting convex strip 5, and the sample storage tube 3 is slidably connected to the outer side of the limiting convex strip 5. The inner wall of the sampling tube 2 is slidably connected with a fixed pressure plate 6, and the fixed pressure plate 6 and the sample storage tube 3 are arranged in a close-fitting shape. The top of the fixed pressure plate 6 is rotatably connected with a connecting rod 7. The outer wall of the sampling tube 2 is fixedly installed with a gear ring 8, and the outer side of the gear ring 8 is meshed with a gear 9. The inner wall of the main body 1 is fixedly installed with a motor 10, and the gear 9 is fixedly installed at the output end of the motor 10. Figure 1 As shown, a top cover 11 is hingedly connected to the top of the sampling tube 2.

[0022] It should be noted that, when soil sampling is carried out, the sample storage tube 3 is inserted into the interior of the sampling tube 2 and fits with the cutter head 4, and the inner diameter of the cutter head 4 is the same as the inner diameter of the sampling tube 2, and the top cover 11 is closed and the connecting rod 7 is rotated to lower the fixed pressure plate 6. When the fixed pressure plate 6 fits with the sample storage tube 3, the sample storage tube 3 is fixed. At this time, the motor 10 is started to rotate the gear 9 and engage with the gear ring 8, thereby prompting the sampling tube 2 to rotate and drill into the ground through the cutter head 4. At the same time, the sample soil inside the sample storage tube 3 enters the interior of the sample storage tube 3. After the collection is completed, the sampling tube 2 is pulled out from the ground, and the sampling tube 2 is placed horizontally on the ground. The connecting rod 7 is rotated to raise the fixed pressure plate 6, and the top cover 11 is opened to pour the sample storage tube 3 out of the interior of the sampling tube 2. At this time, the empty sample storage tube can be replaced. 3 is fixed in the sampling tube 2, so that sampling can continue. After the storage tube 3 containing the sample soil is taken out from the interior of the sampling tube 2, the sealing cover 20 is fixed to the bottom of the storage tube 3 to seal the storage tube 3 to prevent the soil from spilling out during transportation. When the sample soil needs to be taken out from the storage tube 3, the pushing screw 19 is screwed in from the top of the storage tube 3 and plugged into the top of the bulldozer 18 to complete the connection, and the sealing cover 20 is separated. The pushing screw 19 is continuously rotated to make the bulldozer 18 push the sample soil, so that the sample soil can be pushed out from the interior of the storage tube 3, and then the sample soil can be taken out from the interior of the storage tube 3, thereby achieving complete preservation and convenient removal of the sample soil. At the same time, the convenience and efficiency of multiple sampling can be improved by replacing the storage tube 3.

[0023] Further, such as Figure 1 As shown, the connecting rod 7 and the top cover 11 are threadedly connected, and a handle 12 is fixedly installed on one side of the main body 1. Figure 3 As shown, the internal thread of the handle 12 is connected to a screw rod 13, one end of the screw rod 13 is fixedly mounted with a connecting column 14, one end of the connecting column 14 is rotatably connected to a slider 15, the outer side of the slider 15 is slidably connected to a support frame 16, the inner wall of the support frame 16 is fixedly mounted with a limit rod 17, and the slider 15 is slidably connected to the outer side of the limit rod 17, as shown in FIG. Figure 4 As shown, the inner wall of the sample storage tube 3 is slidably connected with a bulldozer 18, the top of the bulldozer 18 is plugged with a propulsion screw 19, the propulsion screw 19 is threadedly connected to the sample storage tube 3, and the bottom of the sample storage tube 3 is threadedly connected with a sealing cover 20.

[0024] It should be noted that, when sampling in areas with harder soil, the two screws 13 are screwed into the interior of the handles 12 on both sides. At this time, the main body 1 can be supported by the support frames 16 on both sides. When drilling downward, the slider 15 drops at the same time. The support of the support frame 16 increases the stability of the sampling tube 2 during sampling, avoids the phenomenon of the sampling tube 2 being difficult to drill into and tilting due to soil problems, and reduces the occurrence of damage to the sampling tube 2.
