Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, specifically a soil and rock sampling device for water conservancy engineering testing. Background Technology
[0002] Water conservancy projects are projects that undertake the tasks of water retention, storage, and discharge. Therefore, they have special requirements for the stability, pressure bearing, seepage prevention, erosion resistance, wear resistance, frost resistance, and crack resistance of hydraulic structures. Special construction methods and measures must be adopted in accordance with the technical specifications of water conservancy projects to ensure project quality. In water conservancy projects, it is necessary to sample and test the local soil and rock to facilitate project calculations. Sampling equipment is inevitably required for soil and rock sampling.
[0003] After deceleration, patent authorization announcement number CN 221404784 U discloses a soil and rock sampling device for water conservancy engineering testing, "including an installation frame and a drive mechanism, wherein the drive mechanism is disposed inside the installation frame, and a sampling cylinder is disposed at the bottom of the drive mechanism. This utility model relates to the field of soil and rock sampling technology. This soil and rock sampling device for water conservancy engineering testing, by sliding two arc-shaped covers inside the sampling cylinder, and by setting an insert plate and a limiting frame between the arc-shaped covers and the sampling cylinder, allows the two arc-shaped covers to stably contact the soil sample instead of the inner wall of the sampling cylinder during sampling, thereby facilitating the subsequent removal of the arc-shaped covers and the sample together, and by peeling off the two arc-shaped covers..." The sampling device allows for complete sample removal, making sample collection more convenient and efficient. Secondly, by placing handles on opposite sides of the two insert plates, the sampling cylinder and the arc-shaped cover are separated, facilitating manual operation. However, after sampling, the operator still needs to pull and lift the handles 13 with both hands to move the two arc-shaped covers 4 upwards, carrying the sample out of the sampling cylinder 3. Then, the two arc-shaped covers 4 must be peeled off the sample surface sequentially to remove the sample. While this method maintains sample integrity, it is still inconvenient and inefficient. Utility Model Content
[0004] The purpose of this invention is to provide a soil and rock sampling device for water conservancy engineering testing, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A soil and rock sampling device for water conservancy engineering testing includes a base and a support. Two supports and two moving wheels are respectively installed at the front and rear of the base. A support is mounted on the base, and a wheel frame is mounted at the top of the support. Guide wheels are mounted on the wheel frame. A winding machine is mounted at the rear of the two supports, and a steel wire rope is wound on the winding machine. The steel wire rope is wound around the guide wheels, and a hanger is attached to the free end of the steel wire rope. A support plate is mounted at the bottom of the hanger, and a slide is mounted at one end of the support plate. The slide is slidably connected to guide rails mounted on the outer walls of the two supports. A rotating shaft is rotatably mounted on the support plate, and a large gear is mounted at the top of the rotating shaft. A small gear meshes with the large gear on one side of the large gear. The small gear is fixedly connected to the output shaft of a second motor fixedly mounted on the support plate. A sampling head is connected to the bottom of the rotating shaft, and a bulldozer plate is installed inside the sampling head. Pressing plates are mounted on both sides of the bulldozer plate.
[0007] As a further embodiment of this utility model: a flange is installed on both the sampling head and the bottom of the rotating shaft, and the sampling head is fixed to the rotating shaft flange.
[0008] As a further improvement of this utility model: the bulldozer plate is a circular plate and is adapted to the sampling head.
[0009] As a further embodiment of this utility model: the winding machine includes a winding roller and a first motor. The winding roller is rotatably mounted on a roller frame that is fixedly connected to a bracket. One end of the winding roller shaft is directly connected to the output shaft of the first motor mounted on the roller frame.
[0010] As a further improvement of this utility model, a directional handle is installed at the rear of the two brackets.
[0011] As a further improvement of this utility model, the base is a U-shaped base.
[0012] As a further improvement of this utility model, the sampling head is provided with sliding tracks on both sides to facilitate the up-and-down movement of the pressing plate and the bulldozing plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model incorporates a bulldozer plate inside the sampling head, with pressing plates extending outwards from both sides of the bulldozer plate. When the sampling head drills into the soil to collect a sample, the bulldozer plate is compressed by the soil and moves upwards to the top of the sampling head. When it is necessary to remove the soil sample from the sampling head, simply press the pressing plates on both sides. The pressing plates will then move the bulldozer plate downwards, thus easily removing the soil sample from the sampling head. Compared with existing technologies, this utility model makes sample removal more convenient and efficient.
[0015] 2. This utility model provides a sampling frame consisting of a base, casters, supports, and brackets. Because it has two casters, the sampling frame can be moved quickly on the ground by personnel, making it more convenient to carry than existing sampling devices.
[0016] 3. This utility model incorporates a large gear, a small gear, a rotating shaft, and a second motor. The second motor drives the sampling head to rotate for sampling through the meshing of the large and small gears. Compared with existing models where the motor directly drives the sampling head, this utility model indirectly drives the sampling head through a gear set via the motor output shaft. The motor output shaft is not affected by the reaction force exerted on the sampling head by the soil and rock during sampling, making it less prone to damage and extending its service life.

Detailed Implementation
[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-3In this embodiment of the present invention, a soil and rock sampling device for water conservancy engineering testing includes a base 1 and a support 4. Two supports 2 and two movable wheels 2 are respectively installed at the front and rear of the base 1. The support 4 is mounted on the base 1, and a wheel frame 5 is mounted on the top of the support 4. Guide wheels 8 are mounted on the wheel frame 5. A winding machine 12 is mounted at the rear of the two supports 4. A steel wire rope 7 is wound on the winding machine 12 and wound around the guide wheels 8. A hanger 13 is attached to the free end of the steel wire rope 7. A support plate 11 is installed at the bottom of the hanger 13. A slide 10 is installed at one end of the support plate 11. The slide 10 is slidably connected to the guide rail 9 installed on the outer wall of the two brackets 4. A rotating shaft 14 is rotatably installed on the support plate 11. A large gear 15 is installed at the top of the rotating shaft 14. A small gear 17 is provided on one side of the large gear 15 and meshes with it. The small gear 17 is fixedly connected to the output shaft of the second motor 16 fixedly installed on the support plate 11. A sampling head 18 is connected to the bottom of the rotating shaft 14.
[0023] The winding machine 12 includes a winding roller 1201 and a first motor 1202. The winding roller 1201 is rotatably mounted on a roller frame that is fixedly connected to the bracket 4. One end of the roller shaft of the winding roller 1201 is directly connected to the output shaft of the first motor 1202 mounted on the roller frame.
[0024] The rear of the two brackets 4 are equipped with directional handles 6. The directional handles 6 make it easier for personnel to push or pull the device and control the direction of movement.
[0025] The base 1 is a U-shaped base. The U-shaped design can prevent the base 1 from blocking the sampling head 18 from moving downward to take samples.
[0026] Please see Figure 1-2 The sampling head 18 is equipped with a bulldozer plate 20, and pressing plates 21 are installed on both sides of the bulldozer plate 20. Flanges 19 are installed on the sampling head 18 and the bottom of the rotating shaft 14. The sampling head 18 is fixed to the rotating shaft 14 flange. The sampling head 18 can be easily disassembled and replaced with sampling heads 18 of different specifications through the flange connection, so as to better meet the sampling needs in different environments.
[0027] The bulldozer plate 20 is a round plate and is adapted to the sampling head 18, which allows the bulldozer plate 20 to push the sample out completely, helping to maintain the integrity of the sample.
[0028] The sampling head 18 has slides 22 on both sides to facilitate the up-and-down movement of the pressing plate 21 and the bulldozing plate 20. This design allows the pressing plate 21 to drive the bulldozing plate 20 through the sampling head 18 to move up and down, thereby ensuring that the sample can be pushed out smoothly.
[0029] The working principle of this utility model is as follows:
[0030] In use, the operator first holds the handle 6 and pushes the device to the sampling position driven by the two moving wheels 2. Then, the device is laid flat, and the winding machine 12 is turned on. The first motor 1202 on the winding machine 12 drives the winding roller 1201 to rotate in the direction of wire feeding. The wire rope 7, guided by the guide wheel 8, drives the support plate 11 to gradually lower. The support plate 11 maintains its stability during movement through the sliding cooperation between the slide block 10 and the guide rail 9 on the bracket 4. When the sampling head 18 touches the ground... When contact is made, the second motor 16 is turned on, which drives the small gear 17 to rotate. The small gear 17 meshes with the large gear 15, which drives the rotating shaft 14 to rotate. The rotating shaft 14 drives the sampling head 18 to rotate and drill into the rock and soil to take samples. After sampling, the sampling head 18 is pulled out of the rock and soil by the winding action of the winding machine 12. Then, the personnel press the pressing plates 21 on both sides of the sampling head 18 or step on the pressing plates 21. The pressing plates 21 drive the bulldozer plate 20 to move downward and quickly take out the sample in the sampling head 18.
[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
