Description

Technical Field

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

[0002] In today's construction environment, the soil at the construction site needs to be tested during construction. In the process of testing and sampling the land at the construction site, a soil sampling device for supervision engineering is needed.

[0003] A Chinese patent (CN218098412U) discloses a sampling device for engineering supervision. The connecting rod is driven by an electric motor to allow the drill bit to drill into the soil. When the collecting plate 2 touches the ground, the collecting plate 1 and the collecting plate 2 are squeezed against each other, causing the compression spring to be relatively compressed. As the drill bit continuously drills downward, the soil is transported in strips from the collecting hole to the filter cover for screening, removing stones and allowing the soil to enter the sampling tube for easy sampling.

[0004] However, in actual use of the above structure, when the electric push rod drives the drill bit to drill downward continuously, since the collection disc and the collection plate are connected only by a compression spring, it is easy for the collection disc and the collection plate to be misaligned due to the shaking of the sampling device during the soil collection process, thereby causing the soil to splash to the outside of the collection plate, and the sampled soil will fall to the outside of the sampling device due to being too loose. Utility Model Content

[0005] In response to the above problems, a soil sampling device for supervision projects is provided. The threaded rod and the soil storage mechanism facilitate soil screening and refinement during the sampling process and prevent soil splashing. After sampling, the soil can be extruded into a shape for easy storage and retrieval.

[0006] In order to solve the problems of the existing technology, the utility model provides a soil sampling device for supervision engineering, which includes a placement tube, a sampling plate that moves vertically in the placement tube, and a moving mechanism for driving the sampling plate to move up and down. The moving mechanism includes a sampling tube and a threaded rod that rotates the sampling tube. The soil sampling device for supervision engineering also includes a loosening mechanism for loosening the soil in the sampling tube and a soil storage mechanism for storing the soil on the sampling tube.

[0007] Preferably, the loosening mechanism further comprises a spiral blade and a rotating rod; the spiral blade is arranged outside the threaded rod and located in the sampling tube; the rotating rod is rotatably arranged outside the threaded rod and located close to the spiral blade.

[0008] Preferably, the soil storage mechanism includes a guide rod and a soil storage piece; the guide rod is arranged in the placement cylinder; the soil storage piece is slidably arranged on the guide rod and is located above the sampling cylinder.

[0009] Preferably, the soil storage mechanism further includes a telescopic spring; the telescopic spring is arranged outside the guide rod, and both ends of the telescopic spring are respectively fixed to the guide rod and the soil storage piece.

[0010] Preferably, the engineering soil sampling device also includes a positioning mechanism for positioning the placement tube; the positioning mechanism includes a mounting block and a penetration rod; the mounting block is arranged outside the placement tube and has a pair; the penetration rod is arranged on the mounting plate and slidably cooperates with the mounting plate.

[0011] Preferably, the engineering soil sampling device is further provided with a closing mechanism for taking soil; the closing mechanism includes a closing door and a guide block; the closing door is rotatably mounted on the placement cylinder; and the guide block is provided on the closing door.

[0012] Preferably, the closing mechanism further comprises a positioning block and a clamping rod; the positioning block is arranged outside the placement cylinder and above the guide block; the clamping rod is slidably arranged on the positioning block and corresponds to the position of the guide block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The utility model provides a threaded rod and a soil loosening mechanism to facilitate direct delivery of soil into the sampling tube, thereby reducing soil splashing.

[0015] 2. The utility model is provided with a soil storage mechanism to facilitate the squeezing of the sampled soil, thereby preventing the soil from being too loose and difficult to shape and store in the sampling tube.

DETAILED DESCRIPTION

[0027] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] See also Figure 1 and Figure 9 As shown, a soil sampling device for supervision engineering includes a placement tube 1, a sampling plate 2 that moves vertically in the placement tube 1, and a moving mechanism 3 for driving the sampling plate 2 to move up and down. The moving mechanism 3 includes a sampling tube 31 and a threaded rod 32 that rotates the sampling tube 31. The soil sampling device for supervision engineering also includes a loosening mechanism 4 for loosening the soil in the sampling tube 31 and a soil storage mechanism 5 for storing the soil on the sampling tube 31. The threaded rod 32 is threadedly connected to the placement tube 1 and one end of the threaded rod 32 is fixed to the sampling tube 31. The sampling tube 31 is provided with a hole groove for the loosened soil to pass through. The upper end of the threaded rod 32 is provided with a rotating handle for controlling the rotation of the threaded rod 32. The outside of the rotating handle is detachably provided with an elastic sleeve, and the elastic sleeve is used to relieve user fatigue.

[0029] By rotating the threaded rod 32 , the sampling tube 31 is driven to be spirally inserted into the ground. During the insertion, the soil enters the sampling tube 31 and the soil can be screened by setting the loosening mechanism 4 to prevent larger gravel from entering the sampling tube 31 .

[0030] See also Figure 3 and Figure 5As shown, the loosening mechanism 4 also includes a spiral piece 41 and a rotating rod 42; the spiral piece 41 is arranged on the outside of the threaded rod 32 and is located in the sampling barrel 31; the rotating rod 42 is rotatably arranged on the outside of the threaded rod 32 and is located close to the spiral piece 41, and the rotating rod 42 is provided with several spiral pieces 41. The spiral piece 41 is divided into an upper and lower part. The lower part of the spiral piece 41 is provided with several circular screening openings for screening larger particles of gravel, and the upper part of the spiral piece 41 is used to transport the screened soil. The bottom end of the placement barrel 1 is placed near the outer wall of the sampling barrel 31 with several scrapers for scraping off the soil. The scrapers can scrape the soil on the outer wall of the sampling barrel 31 when the sampling barrel 31 rises and falls.

[0031] The spiral blade 41 is used to screen the soil in the sampling tube 31, which can prevent larger soil from being collected when sampling the soil. The soil can fully contact the rotating rod 42 under the spiral upward action of the spiral blade 41, and the rotating rod 42 is driven to rotate during the contact process between the soil and the rotating rod 42 to loosen the agglomerated soil. At the same time, the gravel in the soil can be further screened for a second time, which to a certain extent reduces the possibility of soil accumulation in the sampling tube 31.

[0032] See also Figure 3 and Figure 5 As shown, the soil storage mechanism 5 includes a guide rod 51 and a soil storage piece 52; the guide rod 51 is arranged in the placement tube 1; the soil storage piece 52 is slidably arranged on the guide rod 51 and is located above the sampling tube 31, and the guide rod 51 is provided with a plurality of guide grooves for the guide rod 51 to pass through, and a limiting piece for limiting the moving distance of the soil storage piece 52 is provided below the guide rod 51. The upper end of the sampling tube 31 is fixed to the sampling plate 2, and the sampling plate 2 is provided with a through groove for the soil to pass through.

[0033] Driven by the spiral piece 41, the soil spirally rises in the sampling tube 31 and passes above the sampling tube 31, so that the soil contacts the sampling plate 2. Under the continuous upward action of the spiral piece 41 and the squeezing of the soil storage piece 52, the soil is driven to rise to the sampling plate 2 and pass through the soil storage piece 52 attached above the sampling plate 2, so that the soil is driven to form between the sampling plate 2 and the soil storage piece 52, which is convenient for storing the refined soil and can also prevent the soil from loosening and falling in the sampling tube 31 due to the loose soil.

[0034] See also Figure 5 and Figure 6 As shown, the soil storage mechanism 5 also includes a telescopic spring 53; the telescopic spring 53 is arranged on the outside of the guide rod 51, and the two ends of the telescopic spring 53 are respectively fixed to the guide rod 51 and the soil storage piece 52. A limiting hole for the threaded rod 32 to pass through is provided on the soil storage piece 52, and the soil storage piece 52 is fixed to the outside of the threaded rod 32 and is not threadedly connected to the threaded rod 32.

[0035] When the soil contacts the soil storage piece 52 above the sampling plate 2, the soil storage piece 52 can perform relative extrusion molding on the soil on the sampling tube 31 under the pushing force of the telescopic spring 53 set on the outside of the guide rod 51. After the sampling is completed, the threaded rod 32 is reversed, causing the sampling tube 31 to move out of the placement tube 1, thereby facilitating the cleaning of the soil in the sampling tube 31.

[0036] See also Figure 6 and Figure 7 As shown, the engineering soil sampling device also includes a positioning mechanism 6 for positioning the placement tube 1; the positioning mechanism 6 includes a mounting block 61 and a penetration rod 62; the mounting block 61 is arranged on the outside of the placement tube 1 and has a pair; the penetration rod 62 is arranged on the mounting plate and slidably cooperates with the mounting plate, and a pedal for the user to step on with his feet is provided above the penetration rod 62, and a reset spring is provided on the outside of the penetration rod 62. The bottom of the penetration rod 62 is in the shape of a needle, and the two ends of the reset spring are respectively fixed to the penetration rod 62 and the end of the mounting plate.

[0037] When the position of the placement tube 1 needs to be fixed, the user steps on the pedal, causing the penetration rod 62 to be pressurized and the return spring to be compressed, so that the bottom of the penetration rod 62 is inserted into the ground. When collecting soil, the placement tube 1 can be fixed to the ground to prevent the soil collection efficiency from being reduced due to shaking during collection.

[0038] See also Figure 6 and Figure 7 As shown, the engineering soil sampling device is also provided with a closing mechanism 7 for taking soil; the closing mechanism 7 includes a closing door 71 and a guide block 72; the closing door 71 is rotatably mounted on the placement cylinder 1; the guide block 72 is provided on the closing door 71, and an escape groove for closing and opening the closing door 71 is provided on the outside of the placement cylinder 1, and a rubber block for sealing between the closing door 71 and the escape groove is provided at the contact position between the closing door 71 and the escape groove, and a circular groove is provided on the guide block 72.

[0039] By opening the closing door 71 , it is easy to take out the soil accumulated on the soil storage piece 52 and the sampling tube 31 , thereby facilitating the storage and sampling of the soil.

[0040] See also Figure 1 and Figure 7 As shown, the closing mechanism 7 also includes a positioning block 73 and a latching rod 74; the positioning block 73 is arranged on the outside of the placement tube 1 and is located above the guide block 72; the latching rod 74 is slidably arranged on the positioning block 73 and corresponds to the position of the guide block 72, and a return spring is arranged on the outside of the latching rod 74, which is used to drive the latching rod 74 to always contact and engage with the guide block 72, so that the closing door 71 is in a closed state under normal conditions.

[0041] When taking the soil above the soil storage piece 52, first pull the clamping rod 74 upward, thereby causing the clamping rod 74 to move out of the outside of the guide block 72. At this time, the closing door 71 can be opened to take the formed soil.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
