Description

Technical Field

[0001] This utility model relates to the field of drilling sampling, and in particular to a drilling sampler. Background Technology

[0002] Drilling sampling is a technique for obtaining samples from underground by drilling holes. It is widely used in geological exploration, mineral resource assessment, hydrogeological surveys, and engineering construction. Its purpose is to analyze and understand underground geological structures, mineral resource reserves, groundwater distribution, and the physical and mechanical properties of foundation soil by obtaining rock and soil samples at a specific depth and location underground.

[0003] Chinese Patent No. CN 220133888 describes "a drilling sampler". When in use, when rotating the threaded rod, the drive motor is started first. The working end of the drive motor rotates, which drives the small gear to rotate. The small gear drives the large gear to rotate, and the large gear drives the brush to rotate. At this time, the nut seat on the threaded rod moves, which in turn drives the brush and the annular brush to move. The inner wall of the annular brush first contacts the impurities on the outer wall of the threaded rod to clean a portion of them. Then, the rotating brush further cleans the impurities on the outside of the threaded rod.

[0004] However, the following defects and shortcomings still exist in the application implementation process:

[0005] To achieve cleaning of the threaded rod, a drive motor is added as a power device, which increases its production cost and also generates more energy consumption.

[0006] Therefore, it is necessary to provide a new drilling sampler to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a drilling sampler.

[0008] The drilling sampler provided by this utility model includes a single helical screw, a transmission seat connected to the single helical screw, a sampling mechanism fixed on the transmission seat, and further includes:

[0009] The cleaning assembly consists of two sets, fixed to the upper and lower ends of the transmission seat. The cleaning assembly includes a first mounting frame that can rotate circumferentially and is in the shape of a ring. The single helical screw passes concentrically through the first mounting frame. A second mounting frame is fixed on the first mounting frame. Brush bristles that contact the single helical screw are fixed on the second mounting frame.

[0010] The transmission mechanism is connected to the sampling mechanism and the first mounting frame. When the sampling mechanism is running, the transmission mechanism drives the first mounting frame to rotate circumferentially.

[0011] Preferably, the sampling mechanism includes a motor base, which is bolted to a transmission base. A motor is installed inside the motor base, and a first transmission shaft is connected to the output flange of the motor. A drill bit is bolted to the other end of the first transmission shaft.

[0012] Preferably, the cleaning assembly further includes a positioning ring frame, which is bolted to the transmission seat. The single helical screw also concentrically passes through the positioning ring frame. The first mounting bracket is rotatably mounted on the positioning ring frame via a bearing. The outer circumferential wall of the first mounting bracket has a belt groove.

[0013] Preferably, there are two second mounting brackets, each in a semi-circular shape. Both second mounting brackets are bolted to the first mounting bracket, forming a complete circular ring concentric with the single helical screw.

[0014] Preferably, the transmission mechanism includes a first pulley, which is concentrically fixed on the first transmission shaft and located near the top.

[0015] It also includes a second drive shaft rotatably connected to the drive base, on which a second pulley and a third pulley are fixed concentrically arranged. The first pulley and the second pulley are connected by a first drive belt, and the third pulley and the belt groove are connected by a second drive belt.

[0016] Preferably, the diameter of the third pulley is larger than the diameter of the belt groove.

[0017] Compared with related technologies, the drilling sampler provided by this utility model has the following beneficial effects:

[0018] This utility model provides a drilling sampler in which, during the drilling and sampling process, the first mounting frame and the second mounting frame can be driven to rotate circumferentially through the transmission mechanism, thereby using bristles to clean the single helical screw. Therefore, the kinetic energy of the sampling mechanism can be better utilized, reducing the production and use costs of the device. Attached Figure Description

[0025] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 4 This utility model provides a drilling sampler, which includes a single helical screw 1, a transmission seat 2 connected to the single helical screw 1, a sampling mechanism fixed on the transmission seat 2, and further includes:

[0030] Cleaning component 6, which consists of two sets, is fixed at the upper and lower ends of transmission base 2. Cleaning component 6 includes a first mounting frame 63 that can rotate in a circular shape, a single helical screw 1 that passes concentrically through the first mounting frame 63, a second mounting frame 65 that is fixed on the first mounting frame 63, and brush bristles 66 that are in contact with the single helical screw 1 that are fixed on the second mounting frame 65.

[0031] The transmission mechanism 7 is connected to the sampling mechanism and the first mounting frame 63. When the sampling mechanism is running, the transmission mechanism 7 drives the first mounting frame 63 to rotate circumferentially.

[0032] It should be noted that this device is the main sampling structure in the entire sampler. That is, the transmission seat 2 can be raised and lowered by the single helical screw 1, which in turn drives the sampling mechanism to rise and fall together, so that the sampling mechanism can drill and sample the soil.

[0033] The cleaning component 6 is used to clean the single helical screw 1, thereby removing dirt embedded in the threads to reduce wear and extend its service life. The transmission mechanism 7 is used for transmission; that is, when the sampling mechanism is drilling, it can drive the first mounting bracket 63 and the second mounting bracket 65 to rotate through the transmission mechanism 7, thereby using the bristles 66 to sweep away dirt on the single helical screw 1 and clean it. This design does not require a separate power unit for the cleaning component 6, reducing the production and operating costs of the device.

[0034] In the embodiments of this utility model, please refer to Figure 1 The sampling mechanism includes a motor base 3, which is bolted to a transmission base 2. A motor is installed inside the motor base 3, and a first transmission shaft 4 is connected to the output flange of the motor. A drill bit 5 is bolted to the other end of the first transmission shaft 4.

[0035] It should be noted that in the sampling mechanism, the motor can drive the drill bit 5 to rotate through the first transmission shaft 4, thereby using the drill bit 5 to perform drilling.

[0036] In the embodiments of this utility model, please refer to Figure 3 The cleaning component 6 also includes a positioning ring frame 61, which is bolted to the transmission seat 2. The single helical screw 1 also passes concentrically through the positioning ring frame 61. The first mounting frame 63 is rotatably mounted on the positioning ring frame 61 through the bearing 62. The outer circumference of the first mounting frame 63 has a belt groove 64.

[0037] There are two second mounting brackets 65, both of which are semi-circular. Both second mounting brackets 65 are bolted to the first mounting bracket 63, forming a complete ring concentric with the single helical screw 1.

[0038] It should be noted that in the cleaning component 6, the positioning ring frame 61 is the basic mounting structure, and the first mounting frame 63 is mounted on the positioning ring frame 61 through the bearing 62, so the first mounting frame 63 can rotate circumferentially.

[0039] The second mounting bracket 65 consists of two sets, and it can be removed from the first mounting bracket 63, making it convenient to replace the bristles 66 when they are severely damaged due to prolonged use.

[0040] In the embodiments of this utility model, please refer to Figure 4 The transmission mechanism 7 includes a first pulley 71, which is concentrically fixed on the first transmission shaft 4 and located near the top.

[0041] It also includes a second drive shaft 72 rotatably connected to the drive base 2, on which a second pulley 73 and a third pulley 74 are fixedly arranged concentrically. The first pulley 71 and the second pulley 73 are connected by a first drive belt 75, and the third pulley 74 and the belt groove 64 are connected by a second drive belt 76.

[0042] The diameter of the third pulley 74 is larger than the diameter of the belt groove 64.

[0043] It should be noted that in the transmission mechanism 7, the first pulley 71 is fixed on the first transmission shaft 4. Therefore, when the sampling mechanism is running, it can drive the first pulley 71 to rotate, and then drive the second transmission shaft 72 and the third pulley 74 to rotate through the first transmission belt 75 and the second pulley 73. The third pulley 74 can then drive the first mounting bracket 63 to rotate through the second transmission belt 76, thus realizing the transmission of power.

[0044] The diameter of the third pulley 74 is larger than the diameter of the belt groove 64, so the rotation speed of the first mounting bracket 63 will be faster, and the cleaning effect on the single helical screw 1 will be better.

[0045] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0046] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
