Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, in particular to a new type of sand sampler. Background Art

[0002] With the continuous expansion of the fields involved in geotechnical engineering exploration, the diversification and complexity of strata have been revealed through exploration. The geotechnical exploration sand sampler is a survey device that needs to be used during the field geotechnical exploration work.

[0003] Among them, the Chinese patent with the authorization announcement number CN218002951U discloses a new type of geotechnical exploration sand sampler, including a fixed plate, a rotating rod, four telescopic rods, a base, a water tank, a cleaning mechanism, a water delivery mechanism and a drying mechanism. However, the problem of this device is that during the geotechnical sampling process, when collecting soil samples, the inside of the collection cylinder will adhere to mud. If it is not cleaned in time, it may affect the next use. Although the device is provided with a nozzle to spray water into the rotating rod for cleaning, generally the silt in the sampling cylinder has strong adhesion, and simply spraying water by the nozzle for cleaning is completely insufficient. The silt inside the collection cylinder has not been completely cleaned, and then the inside of the sampling cylinder is heated by a hot air blower, which will cause the silt inside the sampling cylinder to solidify, thus affecting the subsequent re-sampling. Therefore, this device has certain limitations in use.

[0004] The Chinese patent with the authorization announcement number CN219957003U provides a new type of geotechnical exploration sand sampler. This device is provided with a cleaning component, which is convenient for flushing the inside of the collection cylinder while achieving efficient collection, keeping the inside of the collection cylinder clean, enabling the device to be repeatedly used, with stronger practicability and a wider application range. The problem of this device is that during the process of taking sand in the collection cylinder, the sand slips off from the inside of the collection cylinder under the action of gravity, resulting in the inability to take out the sand.

[0005] According to the above-mentioned prior art, it can be seen that during the process of taking sand in the existing collection cylinder, there are still problems that the sand slips off from the bottom of the collection cylinder under the action of gravity, making it impossible to sample the sand, and it is difficult to clean the inside of the collection cylinder after sampling.

[0006] In view of this, there is an urgent need for a new type of sand sampler to facilitate the collection of sand. Summary of the Utility Model

[0007] (1) Technical Problems to be Solved

[0031] In order to better explain the utility model for easy understanding, the following will describe the utility model in detail through specific embodiments with reference to the drawings. Among them, the orientation nouns such as "upper", "lower", etc. mentioned in this article are based on Figure 1 the orientation for reference.

[0032] In order to better understand the above technical solutions, the exemplary embodiments of the present invention will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0033] The utility model provides a new type of sand collector, including a handheld frame 1, a collection tube 2 rotatably connected to the handheld frame 1, and a driving mechanism 3 fixed to the handheld frame 1, wherein the driving mechanism 3 is transmission-connected to the collection tube 2. A blocking mechanism 4 is detachably provided in the collection tube 2, and the blocking mechanism 4 is used to block the bottom of the collection tube 2 after the collection is completed by the collection tube 2, so as to prevent the sand and gravel in the collection tube 2 from slipping out of the collection tube 2 due to its own weight after the collection is completed. By providing a detachable blocking mechanism 4, after the collection tube 2 collects sand and gravel, the bottom of the collection tube 2 can be blocked; after the sand and gravel are collected, the blocking mechanism 4 can also be disassembled to clean the inside of the collection tube 2, so as to facilitate reuse.

[0034] The handheld frame 1 is annular in structure and has armrests on both sides. A through hole is provided in the middle of the handheld frame 1 for passing the collection tube 2. A bearing 11 is provided in the through hole. The collection tube 2 passes through the bearing 11 and is rotatably connected to the handheld frame 1.

[0035] A worm gear ring 303 is coaxially fixed to the top of the collection tube 2. The worm gear ring 303 is located at the top of the bearing 11. The worm gear ring 303 is used to connect the drive mechanism 3. A plurality of teeth 202 are provided at the bottom of the collection tube 2. The teeth 202 are arranged circumferentially along the bottom of the collection tube 2 to make the collection tube 2 more labor-saving when inserted into the sand layer. A second spiral blade 201 is spirally arranged along the outer wall of the collection tube 2. By setting the second spiral blade 201, the collection tube 2 is more labor-saving when it is screwed into the sand layer. The combination of the teeth 202 and the second spiral blade 201 makes it easier for the user to complete sand collection using the sand extractor.

[0036] The driving mechanism 3 includes a motor 301 fixed on the handheld frame 1 and a worm 302 connected to the motor 301. The output shaft of the motor 301 is coaxially fixed with the worm 302, and the worm 302 is meshed with the worm wheel ring 303. The motor 301 drives the worm 302 to rotate forward and reverse, and the worm 302 drives the worm wheel ring 303 to rotate, thereby driving the collection tube 2 to rotate.

[0037] The blocking mechanism 4 includes a shaft 401, a first spiral blade 402 fixed at the bottom of the shaft 401, a handle 403 fixed at the top of the shaft 401, and a bolt 404 arranged on the handle 403. The size of the first spiral blade 402 matches the collection tube 2, and the handle 403 is detachably connected to the shaft 401. The first spiral blade 402 is spiral-shaped, and the head and tail ends of the first spiral blade 402 are on the same vertical plane. Although there is a gap between the head and tail ends of the first spiral blade 402 for rotating and inserting into the sand and gravel, because the sand and gravel are in a relatively squeezed and dense state in the collection tube 2, and the gap of the first spiral blade 402 is much smaller than the opening at the bottom of the collection tube 2, the sand and gravel can be prevented from sliding out of the collection tube 2 under the action of gravity by blocking the bottom of the collection tube 2 with the first spiral blade 402.

[0038] The bolt 404 is inserted into the handle 403, and a threaded hole 3031 is provided at the top of the worm gear ring 303 corresponding to the bolt 404, and the threaded hole 3031 matches the bolt 404. After the handle 403 is rotated until the handle 403 and the worm gear ring 303 abut against each other, the bolt 404 is passed through the handle 403 and inserted into the threaded hole 3031, and the handle 403 is fixed on the worm gear ring 303 under the extrusion of the bolt 404.

[0039] See also Figure 1 and Figure 3 As shown, after the sand and gravel are poured into the collecting tube 2, the first spiral blade 402 is screwed into the collecting tube 2 by rotating the handle 403, and when the handle 403 abuts against the worm gear ring 303, the first spiral blade 402 is located at the bottom of the collecting tube 2, and the handle 403 is fixed to the worm gear ring 303 by the bolt 404, and then the collecting tube 2 is taken out from the sand and gravel, which can prevent the sealing mechanism 4 from rotating and the sand and gravel from slipping out of the collecting tube 2, resulting in collection failure.

[0040] The working principle of the new sand extractor is as follows:

[0041] Hold the handheld frame 1 with both hands, and drive the worm 302 to rotate through the motor 301. The worm 302 drives the worm gear ring 303 and the collection tube 2 to rotate forward. Under the action of the second spiral blade 201 and the teeth 202, the collection tube 2 is inserted into the sand layer. Then, the first spiral blade 402 is placed on the upper end of the collection tube 2, and the handle 403 is turned forward to make the first spiral blade 402 screwed into the bottom of the collection tube 2. When the handle 403 is against the worm gear ring 303, the bolt is then threadedly connected to the threaded hole 3031. Finally, the motor 301 is used to drive the collection tube 2 to reverse, so that the sand and gravel in the collection tube 2 can be taken out to prevent the sand and gravel from falling. Finally, the sand and gravel sampled in the sealing mechanism 4 and the collection tube 2 can be poured out.

[0042] The utility model provides a novel sand collector. Through the combined setting of a handheld frame 1, a collection cylinder 2 and a driving mechanism 3, the collection cylinder 2 can be inserted into the sand layer to be collected to collect sand and gravel. By arranging a rotatable blocking mechanism 4 in the collection cylinder 2, the sand and gravel collected in the collection cylinder 2 can be blocked, and the blocking mechanism 4 is fixed on the collection cylinder 2 to prevent the sand and gravel from all falling outside the collection cylinder 2 due to its own weight.
