Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to a portable geological exploration soil sampling device. Background Art

[0002] The main purpose of geological exploration and soil sampling is to obtain original data on the engineering geological conditions of the construction site and related areas, and to conduct engineering geological assessments.

[0003] Currently, soil extraction devices are used to assist in the process of soil extraction during geological exploration, in order to increase the convenience of soil extraction.

[0004] A portable geological exploration and soil sampling device, disclosed in prior art (CN219038446U), includes a rotating rod. A frame is fixedly connected to the arc surface of the rotating rod. A motor is installed inside the frame. A rotating shaft is installed on the lower surface of the motor. A drill bit is installed on the lower surface of the rotating shaft. A limiting device is provided on the arc surface of the rotating rod. The limiting device includes a limiting ring, which is sleeved on the arc surface of the rotating rod. Two screws are threadedly connected to the arc surface of the limiting ring.

[0005] While the device facilitates the operation of the soil sampling device by the staff, it was found in actual application that it only has one storage chamber, which is the inner cavity of the rotating rod body. Therefore, when sampling at multiple points, multiple sample storage cylinders need to be carried, which is also quite troublesome and prone to loss or omission. Therefore, an improvement is proposed. Utility Model Content

[0006] This utility model is a portable geological exploration and soil sampling device proposed to overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a portable geological exploration soil sampling device, comprising a cylinder, a partition plate fixedly connected to the inner surface of the cylinder, and a soil sampling component installed between the partition plate and the cylinder.

[0008] A fixing frame is fixedly installed on one side of the outer surface of the cylinder, and a spring limiting rod is installed on the fixing frame;

[0009] The outer surface of the cylinder is rotatably sealed with an annular shell. A waste discharge hole is opened on one side of the outer surface of the annular shell. Multiple storage cavities are evenly opened at the bottom of the annular shell. A sealing cap is threadedly connected to the bottom opening of each of the multiple storage cavities.

[0010] A feeding hole is provided on one side of the outer surface of the cylinder, and through holes are provided on one side of the inner wall of the multiple annular shells and on one side of the inner wall of the waste discharge hole, and the through holes are matched with the feeding hole.

[0011] The top of the annular shell is fixedly connected with multiple positioning rings, and the positioning rings are matched with the spring limiting rods.

[0012] Furthermore, the soil sampling assembly includes a motor, which is fixedly installed on the top of the cylinder. The drive end of the motor is fixedly connected to a rotating shaft, which extends through the top of the cylinder to the bottom. A partition is rotatably sleeved on the outer surface of the rotating shaft. A helical blade is fixedly sleeved on the outer surface of the rotating shaft, and the helical blade is in contact with the inner wall of the cylinder. The motor arrangement facilitates the electric drive of the rotating shaft to rotate.

[0013] Furthermore, a drill bit is fixedly connected to the bottom of the rotating shaft. The maximum outer diameter of the drill bit is slightly larger than the outer diameter of the cylinder, which facilitates drilling and sampling.

[0014] Furthermore, the spring limiting rod includes a stroke hole that extends through the outer wall of the fixing frame to the interior. The stroke hole and the inner top of the fixing frame are fixedly connected to a spring. The bottom of the spring is fixedly connected to a movable plate. The bottom of the movable plate is fixedly connected to a limiting rod body. The limiting rod body extends through the fixing frame and matches the positioning ring. The spring ensures that the limiting rod body is always in the extended state when there is no external force.

[0015] Furthermore, the movable plate slides against the inner walls on both sides of the travel hole, and the travel hole has a limiting effect on the movable plate, which can ensure the stability of the movable plate's movement.

[0016] Furthermore, the top of the annular shell is uniformly provided with multiple markings that match the storage cavity for easy identification.

[0017] Furthermore, handles are fixedly connected to both sides of the outer surface of the cylinder, and rubber sleeves are fixedly fitted onto the outer surfaces of both handles. The rubber sleeves have a shock-absorbing effect and can increase the comfort of use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 3 As shown, a portable geological exploration soil sampling device is disclosed, comprising a cylinder 1, a partition 10 fixedly connected to the inner surface of the cylinder 1, and a soil sampling assembly installed between the partition 10 and the cylinder 1. The soil sampling assembly includes a motor 3, which is fixedly installed at the top of the cylinder 1. A rotating shaft 14 is fixedly connected to the drive end of the motor 3, and the rotating shaft 14 extends through the top of the cylinder 1 to the bottom. The partition 10 is rotatably sleeved on the outer surface of the rotating shaft 14, and the partition 10 and the rotating shaft 14 are sealed by a sealing ring. A spiral blade 15 is fixedly sleeved on the outer surface of the rotating shaft 14. Due to the design of the spiral blade 15, this application is not suitable for sampling in areas with high soil viscosity. The spiral blade 15 is in close contact with the inner wall of the cylinder 1. A drill bit 7 is fixedly connected to the bottom of the rotating shaft 14. The function of the drill bit 7 is to break the soil and facilitate drilling and sampling.

[0028] An annular shell 5 is rotatably connected to the outer surface of the cylinder 1. A sealing sleeve is provided on the outer surface of the cylinder 1 to ensure the sealing of the connection between the annular shell 5 and the cylinder 1. A waste discharge hole 6 is opened on one side of the outer surface of the annular shell 5. Multiple storage cavities 12 are evenly opened at the bottom of the annular shell 5. A sealing cap 13 is threaded to the bottom opening of each of the multiple storage cavities 12. The sealing cap 13 has a sealing effect on the storage cavities 12. A feeding hole 11 is opened on one side of the outer surface of the cylinder 1. Through holes are opened on one side of the inner wall of each of the multiple annular shells 5 and one side of the inner wall of the waste discharge hole 6. The through holes match the feeding hole 11. The through holes allow the feeding hole 11 to communicate with the corresponding waste discharge hole 6 or storage cavity 12.

[0029] A fixed frame 9 is fixedly installed on one side of the outer surface of the cylinder 1. A spring limiting rod is installed on the fixed frame 9. Multiple positioning rings 4 are fixedly connected to the top of the annular shell 5. The positioning rings 4 match the spring limiting rod. The spring limiting rod includes a stroke hole 17, which extends through the outer wall of the fixed frame 9 to the inside. A spring 16 is fixedly connected to the stroke hole 17 and the inner top of the fixed frame 9. A movable plate 18 is fixedly connected to the bottom of the spring 16. A limiting rod body 19 is fixedly connected to the bottom of the movable plate 18. The limiting rod body 19 passes through the fixed frame 9 and matches the positioning rings 4. The movable plate 18 slides against the inner walls on both sides of the stroke hole 17. The spring 16, the movable plate 18, the limiting rod body 19 and the positioning rings 4 cooperate to limit the position of the annular shell 5.

[0030] Multiple markings are evenly distributed on the top of the annular housing 5. These markings can be numbered to facilitate the differentiation of each storage cavity 12.

[0031] Handles 8 are fixedly connected to both sides of the outer surface of the cylinder 1. Rubber sleeves 2 are fixedly fitted onto the outer surface of both handles 8. The handles 8 and rubber sleeves 2 are designed to facilitate hand operation. The rubber sleeves 2 are made of rubber with shock absorption effect to increase the comfort of use.

[0032] Working principle: Upon reaching the sampling point, the movable plate 18 lifts the limiting rod body 19, disengaging it from the positioning ring 4. Then, the annular housing 5 is rotated to align the waste discharge hole 6 with the feeding hole 11. The movable plate 18 is then released, and the spring 16 pushes the movable plate 18 and the limiting rod body 19 back to their original positions, allowing the limiting rod body 19 to insert into the corresponding positioning ring 4. Next, the motor 3 is started by hand-operating via the rubber sleeve 2. The motor 3 drives the rotating shaft 14 to rotate, which in turn drives the drill bit 7 and the spiral blades 15 to rotate, allowing for drilling movement. The soil is then moved within the spiral blades 15. Under the action of 5, the soil rises and is discharged through the feeding hole 11 and the waste discharge hole 6, then falls to the ground. After a certain amount of soil is discharged, the motor 3 stops running. Then the limit on the annular shell 5 is released, and the annular shell 5 is rotated so that the corresponding storage cavity 12 corresponds to the feeding hole 11. Then the annular shell 5 is limited again, and the motor 3 runs a second time. All components work together to transport the soil into the storage cavity 12 until the set amount of soil is taken out. Then the motor 3 stops running, the whole thing is taken out, and then the annular shell 5 is rotated again so that the waste discharge hole 6 corresponds to the feeding hole 11.
