Technical Field
[0001] The utility model relates to a sampling device, in particular to a geological survey sampling device, belonging to the technical field of soil sampling devices. Background Art
[0002] Geological exploration is a scientific and technological activity that mainly uses geophysical, geochemical, geobiological and other methods to detect and study the earth's crust, mantle, core, etc. In the process of geological exploration, it is often necessary to conduct chemical analysis on the composition of the surface soil of the crust, so a sampling device is needed to sample the soil.
[0003] However, when using traditional sampling devices, sampling is mostly achieved by the sampling personnel manually inserting the sampling tube into the ground. This process requires a lot of physical strength, resulting in poor operating comfort. After the sampling is completed, the soil may also adhere to the inside of the sampling tube. At this time, it is necessary to use tools to repeatedly knock the sampling tube to remove the soil sample, which is inconvenient for the soil sample to be removed, resulting in poor operating convenience. Utility Model Content
[0004] The purpose of the utility model is to provide a geological survey sampling device in order to solve the above-mentioned problems, which can save more labor during sampling and can realize the rapid removal of soil samples after the sampling is completed, thereby improving the comfort and convenience of operation.
[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a geological survey sampling device, comprising a base plate, a vertical pole fixedly connected to the base plate, a sampling structure provided on the vertical pole, the sampling structure comprising a threaded sleeve and a screw rod, the top end of the vertical pole is rotatably connected to the threaded sleeve, the screw rod is threadedly connected to the threaded sleeve, the bottom end of the screw rod is fixedly connected to a connecting sleeve, one side of the connecting sleeve is fixedly connected to a guide rod, the guide rod is slidably connected to the vertical pole, a sampling barrel and a baffle are clamped at the bottom end of the connecting sleeve, one side of the baffle is in contact with one side of the sampling barrel, the end of the baffle is clamped with the sampling barrel, the end of the sampling barrel is threadedly connected to the sampling sleeve, a clamping structure is provided on the connecting sleeve, and two handles are fixedly connected to both sides of the threaded sleeve.
[0006] Preferably, the cross-section of the handle is L-shaped, and the two handles are symmetrically distributed about the middle of the threaded sleeve.
[0007] Preferably, the cross-section of the top end of the vertical pole is L-shaped, and the cross-section of the bottom end of the sampling sleeve is sharp-edged.
[0008] Preferably, the locking structure includes a connecting block and a first guide shaft, two connecting blocks are fixedly connected to the connecting sleeve, the connecting block is fixedly connected to the first guide shaft, two first guide shafts located on the same side of the two connecting blocks are slidably connected to the same connecting piece, a clamping plate is fixedly connected to the connecting piece, one of the clamping plates is clamped with the baffle, and the other clamping plate is clamped with the sampling tube.
[0009] Preferably, a first spring is sleeved on the exterior of the first guide shaft, one end of the first spring is fixedly connected to the connecting plate, and the other end of the first spring is fixedly connected to the connecting block.
[0010] Preferably, the cross-section of one end of the clamping plate is a trapezoidal structure, a push rod is fixedly connected to the connecting piece, and the cross-section of the end of the push rod is an L-shaped structure.
[0011] Preferably, a connecting shaft is rotatably connected to the base plate, and two supporting rods are fixedly connected to the connecting shaft.
[0012] Preferably, a limiting structure is provided on the vertical pole, and the limiting structure includes a second guide shaft and a connecting rod.

[0014] Preferably, the cross section of the protrusion is a rectangular structure, and the cross section of the clamping rod is a U-shaped structure.
[0015] The beneficial effect of the utility model is that when in use, one of the handles can be rotated to drive the threaded sleeve to rotate. When one handle is rotated 180 degrees, the other handle can be rotated, so that the two handles are rotated alternately to realize the rotation of the threaded sleeve. Due to the sliding between the guide rod and the vertical rod, the connecting sleeve can only move along the sliding direction of the guide rod and cannot rotate. Therefore, when the threaded sleeve rotates, the screw rod will drive the connecting sleeve to move, and the connecting sleeve drives the sampling barrel to move toward the ground.

[0029] As a technical optimization solution of the utility model, Figure 3 , Figure 6 and Figure 7 As shown, the positioning structure 4 includes a connecting block 401 and a first guide shaft 402. The connecting sleeve 304 is fixedly connected with two connecting blocks 401, and the connecting block 401 is fixedly connected with the first guide shaft 402. The two first guide shafts 402 located on the same side of the two connecting blocks 401 are slidably connected with the same connecting piece 405, and the connecting piece 405 is fixedly connected with a clamping plate 406, one of the clamping plates 406 is clamped with the baffle 307, and the other clamping plate 406 is clamped with the sampling tube 307. 6, the outer sleeve of the first guide shaft 402 is provided with a first spring 403, one end of the first spring 403 is fixedly connected to the connecting piece 405, and the other end of the first spring 403 is fixedly connected to the connecting block 401, the cross-section of one end of the clamping plate 406 is a trapezoidal structure, and a push rod 404 is fixedly connected to the connecting piece 405, and the cross-section of the end of the push rod 404 is an L-shaped structure, so that the sampling tube 306 and the connecting sleeve 304 can be quickly separated, thereby facilitating the removal of soil samples.
[0030] As a technical optimization solution of the utility model, Figure 1 and Figure 4 As shown, a connecting shaft 6 is rotatably connected to the bottom plate 1, and two supporting rods 5 are fixedly connected to the connecting shaft 6. Therefore, the device can be supported by the two supporting rods 5, thereby improving the stability during sampling.
[0031] As a technical optimization solution of the utility model, Figure 4 and Figure 5As shown, a limiting structure 7 is provided on the vertical pole 2, and the limiting structure 7 includes a second guide shaft 701 and a connecting rod 703. Two second guide shafts 701 are fixedly connected to the vertical pole 2, and the two second guide shafts 701 are slidably connected with the same connecting rod 703. Two clamping rods 704 are fixedly connected at both ends of the connecting rod 703, and two protrusions 705 are fixedly connected to the connecting shaft 6. The clamping rods 704 and the protrusions 705 are engaged with each other. A second spring 702 is sleeved on the outside of the second guide shaft 701, and one end of the second spring 702 abuts against the connecting rod 703, and the other end of the second spring 702 abuts against the vertical pole 2. The cross-section of the protrusion 705 is a rectangular structure, and the cross-section of the clamping rod 704 is a U-shaped structure. Therefore, when sampling is not required, the two support rods 5 can be folded and stored, thereby reducing space occupancy and making transportation and storage more convenient.
[0032] When the utility model is in use, the sampling device can be carried to the place where sampling is required, and then the bottom plate 1 is placed on the ground. The device can be supported by the two support rods 5 to prevent the device from tipping over. When sampling is required, one of the handles 301 can be rotated, and the rotation of the handle 301 drives the threaded sleeve 302 to rotate. After one handle 301 is rotated 180 degrees, the other handle 301 can be rotated, so that the two handles 301 are rotated alternately to realize the rotation of the threaded sleeve 302. Due to the sliding between the guide rod 305 and the vertical rod 2, the connecting sleeve 304 can only move along the sliding direction of the guide rod 305 and cannot rotate. Therefore, when the threaded sleeve 302 rotates, the screw rod 303 drives the connecting sleeve 304 The connecting sleeve 304 drives the sampling tube 306 to move toward the ground. During the movement of the sampling tube 306, the sampling sleeve 308 will contact the ground and enter the ground. Since the bottom end of the sampling sleeve 308 has a cutting edge, it can save more effort in the process of entering the ground, and the cooperation between the threaded sleeve 302 and the screw rod 303 can also play a labor-saving role, thereby avoiding the need to consume a lot of physical strength and effectively improving the comfort of sampling. When the sampling tube 306 enters the ground, the soil sample will gather between the sampling tube 306 and the baffle 307, thereby realizing soil sampling. After the sampling is completed, the threaded sleeve 302 can be rotated in the opposite direction to reset the sampling tube 306, and then the two push rods 404 can be pressed at the same time. A push rod 404 drives one of the connecting pieces 405 to move on the first guide shaft 402, and the first spring 403 contracts. One of the connecting pieces 405 drives one of the clamping plates 406 to move away from the baffle 307, and the other connecting piece 405 drives the other clamping plate 406 to move away from the sampling barrel 306. When one of the clamping plates 406 and the baffle 307 are not engaged, the other clamping plate 406 is also not engaged with the sampling barrel 306. Then the sampling barrel 306 can be removed from the connecting sleeve 304, and then the baffle 307 is removed from the sampling barrel 306. After the baffle 307 is removed, the soil sample inside the sampling barrel 306 will not be blocked, thereby facilitating the removal of the soil sample and facilitating the cleaning of the sampling barrel 306 and the baffle. The inner wall of the plate 307 is cleaned, thereby ensuring the cleanliness of the inner walls of the sampling tube 306 and the baffle plate 307. In the process of use, the end of the sampling sleeve 308 will be worn. At this time, you only need to twist the sampling sleeve 308 off the end of the sampling tube 306 to replace it, thereby avoiding the need to replace the entire device, effectively saving the cost of use. When the sampling device is not needed, the connecting rod 703 can be pulled. The connecting rod 703 slides on the second guide shaft 701 and drives the clamping rod 704 to move away from the protrusion 705. The second spring 702 contracts. When the clamping rod 704 and the protrusion 705 are not engaged, the support rod 5 can be rotated toward the vertical rod 2. After the two support rods 5 are rotated 90 degrees, the connecting rod 703 is released.At this time, under the action of the second spring 702, the locking rod 704 will be locked with the protrusion 705 again, so that the support rod 5 can be prevented from continuing to rotate. By folding and storing the support rod 5, the space occupied by the device can be reduced, making it more convenient to transport and store.
