Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring and treatment, and more specifically to a pedal-type columnar mud sampler with a foldable pedal. Background Art

[0002] A columnar mud sampler is a device that samples sediments from the ground or the bottom of a water body in a columnar shape. Various drilling machines or earth drills are columnar mud samplers. The purpose of collecting columnar samples is to study the chemical composition of each layer of sediment and the vertical distribution of benthic organisms in the mud. Therefore, the columnar mud sampler must not disrupt the natural layers of the sediment when collecting samples. The basic principle of a columnar mud sampler is to insert a slender mud sampling tube vertically into the bottom sediment. The top of the sampling tube is sealed after the bottom mud is sampled, and the sediment captured in the tube is lifted up for sampling without falling off.

[0003] In actual use of the existing columnar mud sampler, due to the light counterweight of the columnar mud sampler itself, when encountering hard bottom mud during near-shore sampling, the entire mud sampling tube cannot be filled, and manual assistance is required. However, during the stepping process, the nut on the counterweight of the mud sampler is relatively uncomfortable to the foot, and there is severe pain when the sole and heel of the foot step on the nut. The operator's user experience is poor, and the operator's feet are easily misplaced and offset, which poses certain safety hazards. At the same time, long-term use of feet will cause the middle beam of the columnar mud sampler to bend, affecting the service life of the columnar mud sampler. Therefore, there is an urgent need to improve the technology of the columnar mud sampler structure to improve this equipment. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a foot-operated columnar mud sampler with a foldable pedal, which can be achieved by installing an L-shaped connecting frame with a pedal on the mud sampler body when using the foot-operated columnar mud sampler body, and the L-shaped connecting frame and the support frame are limited and fixed by screws, and then the pin is pulled, and the first pedal and the second pedal are unfolded to form a larger foot pedal area, and then the pin can be loosened, and the pin is elastically connected with the spring to bounce into the pin groove, thereby limiting the first pedal and the second pedal to avoid folding during use, so that the operator can increase gravity by stepping on hard bottom mud to fill the mud sampling tube, thereby improving the use effect and avoiding the phenomenon of hurting the feet or bending of the support frame.

[0006] 2. Technical solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0026] By installing an L-shaped connecting frame 8 with a pedal on the mud sampler body 1, the L-shaped connecting frame 8 and the support frame 3 are limited and fixed by screws, and then the pin 15 is pulled, and the first pedal 10 and the second pedal 11 are unfolded to form a larger pedal area, and then the pin 15 can be loosened, and the pin 15 is elastically connected with the spring 17 to bounce into the pin groove 18, thereby limiting the first pedal 10 and the second pedal 11 to avoid folding during use, so that the operator can increase gravity by stepping on hard bottom mud, so as to fill the mud sampling tube 6, improve the use effect, and avoid the phenomenon of hurting the feet or bending of the support frame 3.

[0027] See also Figure 2The first pedal 10 and the second pedal 11 have the same size, and the outer ends of the first pedal 10 and the second pedal 11 are engraved with anti-slip grooves. By engraving anti-slip grooves on the outer ends of the first pedal 10 and the second pedal 11, the wear resistance between the operator's footsteps and the first pedal 10 and the second pedal 11 is enhanced. The front and rear ends of the first pedal 10 are connected to the mounting sleeve 12, and the end of the second pedal 11 corresponding to the mounting sleeve 12 is connected to the mounting tube 13. A through hole 14 is opened inside the mounting sleeve 12, and a latch 15 is slidably connected inside the through hole 14. A spring groove 16 is opened in the mounting sleeve 12 near the outer side of the through hole 14, and a spring 17 is fixedly connected between the inner wall of the spring groove 16 and the outer wall of the latch 15. The spring 17 is wound around the outside of the latch 15, and a latch groove 18 is opened at one end of the mounting tube 13 corresponding to the latch 15.

[0028] See also Figure 2-4 The material of the spring 17 is stainless steel, and a wear-resistant layer is provided at the outer end of the spring 17. By setting the material of the spring 17 to stainless steel, the corrosion resistance of the spring 17 is enhanced. By providing a wear-resistant layer at the outer end of the spring 17, the wear resistance of the spring 17 is improved, and the use effect of the spring 17 is improved. The diamond piece 20 is composed of two V-shaped spring pieces. The size of the diamond piece 20 is consistent with the size of the diamond groove 21. Pull the latch 15 to move the latch 15 out of the latch groove 18, and fold the first pedal 10 and the second pedal 11. The first pedal 10 can drive the diamond piece 20 to move to one side of the diamond groove 21. The diamond piece 20 is composed of two V-shaped spring pieces, which can make the diamond piece 20 undergo a certain degree of elastic deformation and move into the diamond groove 21.

[0029] In the present invention, when using the device, the technicians in the relevant field install an L-shaped connecting frame 8 with a pedal on the mud sampler body 1, and the L-shaped connecting frame 8 and the support frame 3 are fixed by screws, and then the latch 15 is pulled, and the first pedal 10 and the second pedal 11 are unfolded to form a larger pedal area, and then the latch 15 can be loosened, and the latch 15 is elastically connected with the spring 17 and rebounds into the latch groove 18, so as to limit the first pedal 10 and the second pedal 11 to avoid folding during use, so that the operator can increase gravity by stepping on the hard bottom mud, so that the mud sampling tube 6 is fully collected, the use effect is improved, and the phenomenon of foot rubbing or bending of the support frame 3 is avoided;

[0030] When there is no need to use the pedal to assist in collecting mud, the latch 15 can be pulled to remove the latch 15 from the latch slot 18, and the first pedal 10 and the second pedal 11 can be folded and stored. The diamond-shaped piece 20 forms a snap-fit ​​structure with the diamond-shaped slot 21 to facilitate fixing the first pedal 10 and the second pedal 11 after folding, thereby reducing the occupied space of the pedal as a whole. The first pedal 10 and the second pedal 11 are vertically arranged on both sides of the mud collecting device body 1 as a whole, which will not affect the use of the mud collecting device body 1 and is convenient to use.

[0031] When using the mud sampler body 1, the pull rope can be first tied to the lifting ring 22, and then the pull rope is pulled upward to lift the lifting frame 2 so that the pull rope is in a taut state. At this time, the blocks 23 on both sides of the bottom end of the lifting frame 2 rotate and are clamped into the grooves at the corresponding clamping seat 24, so that the blocks 23 are pressed against the column in the middle part of the clamping seat 24, playing a role of stabilizing the limit. If soft bottom mud is encountered, the mud sampler body 1 can directly drive the mud sampling tube 6 for sampling through the gravity of the counterweight block 4 itself. If hard bottom mud is encountered, the first pedal 10 and the second pedal 11 need to be unfolded because the hard bottom mud cannot fill the entire mud sampling tube 6, so that the operator can use foot pedals for auxiliary sampling, thereby improving the sampling effect.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
