Description

Technical Field

[0001] This application relates to the field of sampler design technology, and more specifically, to a solid waste sampler that uses labor-saving techniques. Background Technology

[0002] A sampler is a tool used to collect representative samples from environmental media (such as soil, water, and solid waste), and is widely used in environmental monitoring, quality testing, and other fields. It typically consists of a sampling head, an operating lever, a sample container, and auxiliary components. The sampling head is designed according to the characteristics of the target medium and comes in various types, including spiral, cylindrical, and spoon-shaped. The general sampling method involves first determining the sampling point and depth based on monitoring requirements and cleaning impurities from the sampling point surface; then aligning the sampler with the target location and inserting the sampling head into the medium by manual rotation or mechanical drive to ensure the collection of samples at different depths; after reaching the predetermined depth, withdrawing the sampler to prevent sample loss; finally, transferring the sample from the sampling head to a clean container, labeling it, and completing the sampling process to provide a reliable sample for subsequent analysis.

[0003] Existing samplers often suffer from insufficient structural stability during actual sampling. During sampling, the sampler body is prone to swaying and tilting due to medium resistance or its own unstable center of gravity. Sampling personnel must continuously and firmly hold onto the operating lever or the body to maintain sampling direction and posture. This is especially true when drilling into hard media or conducting deep sampling, where increased resistance leads to more pronounced swaying, requiring continuous arm exertion to counteract the force, easily resulting in soreness and fatigue after prolonged operation. This not only increases labor intensity but can also affect sampling accuracy due to hand tremors, making it particularly inconvenient for single-person operation and sometimes requiring multiple people to work together, thus reducing sampling efficiency.

[0004] Therefore, this application provides a labor-saving solid waste sampler to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides a labor-saving solid waste sampler that effectively reduces the swaying and tilting of the sampler body and saves the physical strength of the sampling personnel.

[0006] To achieve the above objectives, this application provides the following technical solution: a labor-saving solid waste sampler, comprising a frame mechanism, a sampling mechanism disposed inside the frame mechanism, and a stabilizing mechanism disposed at the bottom of the frame mechanism for fixing. The frame mechanism includes a mounting groove, two fixed rods fixedly disposed inside the mounting groove, diagonal braces rotatably connected to the ends of the two fixed rods respectively, and connecting rods rotatably disposed on the diagonal braces. The two diagonal braces located at the same end of the fixed rods rotate in directions away from each other. The two connecting rods located at the same end of the fixed rods are rotatably connected at the end away from the diagonal braces. The end of the diagonal brace away from the fixed rod is connected to a stabilizing mechanism that stabilizes the overall outer frame by fixing the position of the end of the diagonal brace.

[0007] The stabilizing mechanism includes two counterweight plates rotatably connected to the ends of the diagonal brace and rotating wheels rotatably connected to the four corners at the bottom of the counterweight plates. The counterweight plates are located on both sides below the mounting groove.

[0008] Several pins are fixedly installed on the side of the counterweight plate opposite to the rotating wheel to increase the friction of the contact surface.

[0009] The counterweight plate has a vertically penetrating threaded hole, and a sleeve is threaded into the threaded hole. A vertical rod is inserted into the sleeve, and a sliding block is fixedly installed at one end of the vertical rod inside the sleeve. The sliding block has a polygonal cross-section and is slidably connected inside the sleeve. A first limiting plate is provided on one end of the sleeve to limit the sliding block, and the first limiting plate is slidably connected to the vertical rod.

[0010] The sampling mechanism includes a fixed box fixedly connected to the bottom of the mounting groove. A hydraulic cylinder is provided on the fixed box. A hydraulic rod is fixedly connected to the output end of the hydraulic cylinder. A drive motor is fixedly connected to the end of the hydraulic rod away from the hydraulic cylinder. A sampling rod is fixedly connected to the output end of the drive motor.

[0011] The bottom of the fixed box has an opening for receiving. A fixed plate is provided at one end of the hydraulic cylinder near the fixed box. The fixed plate is slidably connected to the opening. A second limiting plate is fixedly provided at the bottom end of the opening. The second limiting plate is slidably connected to the hydraulic cylinder. A buffer spring is provided inside the opening. The two ends of the buffer spring are respectively fixedly connected to the top wall inside the opening and the fixed plate.

[0012] A handrail is fixedly connected to the top of the mounting slot.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: 1. By setting up a rotating wheel, when preparing the sampler for operation, one hand lifts the handrail and places one end of the counterweight plate on the ground. The side of the counterweight plate on which the rotating wheel is mounted faces downward. The rotating wheel on the counterweight plate rotates on the ground, driving the sampler to move. This can avoid the sampling personnel having to move the sampler with great effort when carrying out sampling work and changing sampling points, thus saving the sampling personnel's physical strength. 2. By setting up diagonal braces, this application can better support the sampler by separating the diagonal braces to both sides when reaching the sampling location. When the counterweight plate is rotated, the side of the counterweight plate with the rotating wheel facing upwards and the plate nails contacting the ground and being driven into the ground, the sampling staff can hold the handrail. When the sampling rod in the sampling mechanism drills into the solid waste for sampling, it can more effectively resist vibration. 3. This application uses a hydraulic cylinder. During sampling, the hydraulic cylinder drives the hydraulic rod to move downwards, which in turn drives the drive motor. The drive motor then drives the sampling rod to rotate as it comes into contact with the fixed waste material. The sampling rod penetrates the solid waste material to complete the sampling. During this process, a buffer spring can cushion the vibration generated by the sampling rod, preventing damage to the sampler when it encounters hard waste material. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0018] like Figures 1 to 6 As shown, this application provides a labor-saving solid waste sampler, including a frame mechanism 1, a sampling mechanism 2 disposed inside the frame mechanism 1, and a stabilizing mechanism 3 disposed at the bottom of the frame mechanism 1 for fixing. The frame mechanism 1 includes a mounting groove 11, two fixed rods 12 fixedly disposed inside the mounting groove 11, diagonal braces 13 rotatably connected to the ends of the two fixed rods 12 respectively, and connecting rods 14 rotatably disposed on the diagonal braces 13. The two diagonal braces 13 located at the same end of the fixed rods 12 rotate in directions away from each other. The two connecting rods 14 located at the same end of the fixed rods 12 are rotatably connected at the end away from the diagonal braces 13. The end of the diagonal brace 13 away from the fixed rods 12 is connected to the stabilizing mechanism 3, which stabilizes the overall outer frame by fixing the end position of the diagonal brace 13.

[0019] When the sampler is not in operation, the diagonal brace 13 in the frame mechanism 1 is closed for easy transportation. When the sampler is in operation, the diagonal brace 13 is separated to both sides. The frame mechanism 1 has a triangular structure and strong stability. When sampling, the sampler's drill bit drills into the sampling target, and the sampler will shake. Even if the sampler shakes, the projection of the sampler's center of gravity is always within the sampler's support surface, and the sampler will not tip over. The staff only needs to press the sampler to prevent it from moving excessively, saving some physical effort. The connecting rod 14 is used to limit the diagonal brace 13 to prevent the separation angle from being too large. The stabilizing mechanism 3 is used to stabilize the overall outer frame.

[0020] The stabilizing mechanism 3 includes two counterweight plates 31 rotatably connected to the ends of the diagonal brace 13 and rotating wheels 32 rotatably connected to the four corners at the bottom of the counterweight plates 31. The counterweight plates 31 are located on both sides below the mounting groove 11.

[0021] When the side of the counterweight plate 31 on which the rotating wheel 32 is mounted faces downward, the rotating wheel 32 on the counterweight plate 31 rotates on the ground, driving the sampler to move. This avoids the sampler from having to move it laboriously when sampling work or changing sampling points, thus saving the sampler's physical strength.

[0022] Several nails 33 are fixedly provided on the side of the counterweight plate 31 opposite to the rotating wheel 32 to increase the friction of the contact surface.

[0023] Rotating the counterweight plate 31 so that the side of the counterweight plate 31 opposite the rotating wheel 32 faces downward, then the plate nails 33 on the counterweight plate 31 contact the ground and are driven into the ground, which can more effectively resist vibration.

[0024] The counterweight plate 31 has a vertically penetrating threaded hole 34. A sleeve 4 is threaded into the threaded hole 34. A vertical rod 41 is inserted into the sleeve 4. A sliding block 42 is fixedly installed at one end of the vertical rod 41 inside the sleeve 4. The sliding block 42 has a polygonal cross-section and is slidably connected inside the sleeve 4. A first limiting plate 43 is provided at one end of the sleeve 4 to limit the sliding block 42. The first limiting plate 43 is slidably connected to the vertical rod 41.

[0025] If the vibration is large, the vertical rod 41 can be rotated, which will drive the sliding block 42 to rotate. The sliding block 42 has a polygonal cross-section. Correspondingly, the sleeve 4 has a slide rail that matches the polygonal cross-section of the sliding block 42, so that the sliding block 42 can slide relative to the sleeve 4 but will not rotate relative to the sleeve. Thus, the sliding block 42 drives the sleeve 4 to rotate. The sleeve 4 is threadedly connected to the counterweight plate 31. One end of the sleeve 4 can be set as a pointed tip, which is conducive to drilling into the ground. This can make the sampler more stable. The first limiting plate 43 can prevent the vertical rod 41 from separating from the sleeve 4.

[0026] The sampling mechanism 2 includes a fixed box 21 fixedly connected to the bottom of the mounting groove 11. A hydraulic cylinder 22 is provided on the fixed box 21. A hydraulic rod 23 is fixedly connected to the output end of the hydraulic cylinder 22. A drive motor 24 is fixedly connected to the end of the hydraulic rod 23 away from the hydraulic cylinder 22. A sampling rod 25 is fixedly connected to the output end of the drive motor 24.

[0027] During sampling, the hydraulic cylinder 22 drives the hydraulic rod 23 to move downward, the hydraulic rod 23 drives the drive motor 24, and the drive motor 24 drives the sampling rod 25. While in contact with the fixed waste, the drive motor 24 drives the sampling rod 25 to rotate, and the sampling rod 25 penetrates into the solid waste to complete the sampling.

[0028] The bottom of the fixed box 21 has a receiving opening 211. The hydraulic cylinder 22 is provided with a fixing plate 221 near one end of the fixed box 21. The fixing plate 221 is slidably connected to the receiving opening 211. A second limiting plate 213 is fixedly provided on the bottom end of the receiving opening 211. The second limiting plate 213 is slidably connected to the hydraulic cylinder 22. A buffer spring 212 is provided in the receiving opening 211. The two ends of the buffer spring 212 are respectively fixedly connected to the inner top wall of the receiving opening 211 and the fixing plate 221.

[0029] The buffer spring 212 can buffer the vibration generated by the sampling rod 25 to prevent damage to the sampler when encountering hard waste. In addition, the second limiting plate 213 can prevent the fixing plate 221 from detaching from the receiving port 211.

[0030] A handle 111 is fixedly connected to the top of the mounting slot 11, which can lift the sampler for movement. When the sampler is working, holding the handle 111 can help stabilize the sampler.

[0031] The working principle and usage process of this application: When preparing the sampler, lift the handle 111 with one hand and place one end of the counterweight plate 31 on the ground. The side of the counterweight plate 31 with the rotating wheel 32 facing downwards will rotate, driving the sampler to move. This avoids the sampler being moved laboriously when preparing for sampling or changing sampling points, saving the sampler's energy. Upon reaching the sampling location, spread the diagonal support rod 13 to both sides for better support. Rotate the counterweight plate 31 so that the side with the rotating wheel 32 faces upwards, and the nail 33 contacts the ground and is driven into the ground. The sampling staff can then hold the handle 111, which provides better resistance to vibration when the sampling rod 25 in the sampling mechanism 2 penetrates the solid waste for sampling. If the vibration is significant, the vertical rod 41 can be rotated, causing the sleeve 4 to rotate. The sleeve 4 is threadedly connected to the counterweight plate 31. One end of the sleeve 4 can be designed as a pointed tip, which facilitates drilling into the ground, thus stabilizing the sampler. This allows sampling personnel to save some of the force required to hold the sampler in place, and they can directly step on the counterweight plate 31 with their own weight, greatly reducing the physical effort required to stabilize the sampler. The sleeve 4 is slidably connected to the sliding block 42. When not in use, the sliding block 42 can slide away from the first limit plate 43 on the sleeve 4, preventing the vertical rod 41 from extending too far beyond the counterweight plate 31 and affecting its rotation. During sampling, the hydraulic cylinder 22 drives the hydraulic rod 23 downward, which in turn drives the drive motor 24. The drive motor 24 drives the sampling rod 25, which, upon contact with the fixed waste material, rotates the sampling rod 25, allowing it to penetrate the solid waste and complete the sampling. During this process, the buffer spring 212 can buffer the vibration generated by the sampling rod 25 to prevent damage to the sampler when it encounters hard waste.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
