[0002] In many fields such as geological exploration, soil research, and engineering testing, the soil sampling ring cutter is a key tool for obtaining soil samples. It is a common instrument used to take undisturbed soil samples for experiments such as bulk density, compression, shear, and permeability tests. When using it, the blade should be facing downwards. Avoid tilting when cutting the soil sample and ensure that it is cut vertically and evenly with force. Before use, a small amount of petroleum jelly can be applied to the ring cutter. After use, the ring cutter should be cleaned and coated with some protective oil to prevent rust.
[0003] However, the current methods for removing soil from the ring cutter are inconvenient to operate. Using methods such as knocking or hand-clamping can easily cause soil to scatter and damage the overall soil structure. Therefore, this utility model provides a press-type ring cutter bulldozer to meet people's needs. Utility Model Content

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0024] Example: Figure 1-4As shown, this utility model provides a technical solution for a press-type ring cutter bulldozer, including a base 1, a frame 2 fixedly installed at one end of the top of the base 1, an installation groove 3 inside the top end of the frame 2, a return spring 4 fixedly installed at the top of the installation groove 3, a lifting block 5 fixedly connected to the bottom end of the return spring 4, a movable rod 6 fixedly connected to the bottom end of the lifting block 5, a connecting stud 7 connected to the bottom of the movable rod 6, and a bulldozing block 8 fixedly connected to the bottom end of the connecting stud 7. The movable rod 6 movably passes through the bottom of the frame 2, and the connecting stud 7 and the movable rod 6 are connected by threads, facilitating the disassembly and cleaning of the bulldozing block 8. A pressing block 9 is fixedly connected to one end of the lifting block 5, a guide groove is opened at one end of the frame 2, the guide groove is connected to the installation groove 3, the pressing block 9 is movably engaged in the middle of the guide groove, and the pressing block 9 and the frame 2 are slidably connected. A buffer pad 12 is also included. Located directly below the pressing block 9, a hand grip 10 is fixedly connected to the middle of one end of the pressing block 9. A limit block 11 is fixedly installed at the bottom of one end of the frame 2, and a buffer pad 12 is fixedly bonded to the top of the limit block 11. Through the combined use of the pressing block 9 and the hand grip 10, multiple operating spaces are provided for the staff. The position of the lifting block 5 can be adjusted downward by pressing and gripping with the palm of the hand. Then, the soil in the middle of the ring cutter is pushed out by the bulldozing block 8. The operation is convenient and quick, and the overall structure of the pushed soil is not damaged, which provides convenience for experimental research. The reset spring 4 will then reset and retract to pull the bulldozing block 8 back to its original position automatically. At the same time, the limit block 11 and the buffer pad 12 play a role in positioning and buffering protection for the pressing block 9, making the pressing and bulldozing process more precise and preventing insufficient downward pressing distance from causing the soil inside the ring cutter to not be completely pushed out.
[0025] A positioning frame 13 is fixedly installed at the top of the base 1. A collection box 14 is placed in the middle of the positioning frame 13. Fixing posts 15 are symmetrically fixedly installed on both sides inside the collection box 14. Each fixing post 15 has a splicing groove 16 at its top. A ring cutter placement ring 17 is placed between the tops of the two fixing posts 15. Splicing posts 18 are symmetrically fixedly connected to the two ends of the bottom of the ring cutter placement ring 17. The outer wall of the collection box 14 fits against the inner wall of the positioning frame 13. The splicing posts 18 are movably embedded into the splicing groove 16. (The last sentence appears to be incomplete and possibly refers to bulldozing.) The circular block 8 is located directly above the ring cutter placement ring 17. The positioning frame 13 is used to position the collection box 14, and the collection box 14 is movable, making it easy to remove and process the soil after bulldozing. The splicing column 18 and splicing groove 16 correspond to each other, so that the ring cutter placement ring 17 and the collection box 14 are aligned, thus accurately aligning with the bulldozing circular block 8 and preventing misalignment during bulldozing. At the same time, the disassembly and installation method between the ring cutter placement ring 17 and the collection box 14 is simple, which greatly facilitates the subsequent removal of the collection box 14 separately.
[0026] The base 1 has symmetrically provided grooves 19 on both sides and a notch 20 on one end. A protective cover 21 is installed on the surface of the base 1. A protrusion 22 is fixedly connected to one end of the protective cover 21. A locking screw 23 is installed in the middle of the protrusion 22. L-shaped pressure blocks 24 are symmetrically fixedly connected to the two inner side walls of the protective cover 21. A slider is symmetrically fixedly connected to the two sides of the bottom end of the protective cover 21. The slider is movably engaged in the inside of the groove 19. The protrusion 22 is embedded in the inside of the notch 20. The two L-shaped pressure blocks 24 are respectively tightly attached to the two ends of the top of the ring knife placement ring 17. The protective cover 21 is locked and fixed by the locking screw 23 and the protrusion 22, so that the protective cover 21 covers the top of the base 1, which protects the equipment and makes it easy to lift the equipment as a whole, which greatly facilitates the carrying and handling of the equipment by the staff. At the same time, the L-shaped pressure blocks 24 are used to press and fix the ring knife placement ring 17 and the collection box 14 to prevent them from shaking and falling off during the carrying and transportation process and causing damage.
[0027] The working principle and usage process of this utility model are as follows: First, before soil sampling, the staff prepares by taking the ring cutter placement ring 17 and placing it on top of the collection box 14. The splicing column 18 is embedded in the splicing groove 16, and the protective cover 21 is pushed from one side to the top of the base 1. The slider at the bottom of the protective cover 21 is inserted into the sliding groove 19 and slides along the sliding groove 19 until the protrusion 22 is embedded in the notch 20. The locking screw 23 is used to lock and fix it, so that the protective cover 21 and the base 1 are fixed to each other. At this time, the L-shaped pressure block 24 moves to the side of the ring cutter placement ring 17 along with the protective cover 21. The two L-shaped pressure blocks 24 press on the top of the ring cutter placement ring 17, which plays a role in pressing and stabilizing both the ring cutter placement ring 17 and the collection box 14. The staff uses the protective cover 21 to lift the entire device and transport it to the soil sampling position. The ring cutter placement ring 17 and the collection box 14 are limited and will not shake or fall during transportation.
[0028] Workers use a ring cutter to take soil samples. After sampling, the protective cover 21 is removed and the ring cutter is placed in the middle of the top of the ring cutter placement ring 17. Workers press down on the pressing block 9 with their palm or press down on the handle 10, causing the lifting block 5 to slide down inside the mounting groove 3. The return spring 4 is stretched, and the movable rod 6 and the bulldozing block 8 both descend. The bulldozing block 8 gradually approaches and embeds itself into the ring cutter, pushing the soil in the ring cutter downwards and causing it to fall into the collection box 14. When the pressing block 9 contacts the buffer pad 12, it indicates that the downward pressure distance is sufficient and the bulldozing block 8 can push out all the soil in the ring cutter. Workers release their hands, the return spring 4 retracts upwards to reset, and pulls the lifting block 5 and the bulldozing block 8 back to their original positions.
[0029] Then, remove the soil-pushing ring cutter, pull out the ring cutter placement ring 17, and remove the collection box 14 from the middle of the positioning frame 13. This makes it easier for staff to process the sampled soil that has fallen into the collection box 14. If sampling is required again, a new collection box 14 can be taken, placed in the middle of the positioning frame 13, and the ring cutter placement ring 17 can be installed to carry out subsequent soil pushing operations.
[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
