Description

Technical Field

[0001] The utility model relates to the field of river bottom mud sampling, in particular to a river bottom mud sampler. Background Art

[0002] With the continuous development of social economy and the continuous improvement of human living standards, people pay more and more attention to environmental protection and water resources management. The sampling, analysis and research of river sediments have also become an important link. River sediments refer to the sediment and organic matter deposited in rivers. They are an important component of river ecosystems. The study of river sediments is of great significance for understanding the health of river ecosystems, the distribution and migration of pollutants and the protection of biodiversity.

[0003] Most of the existing samplers used for river sediment sampling require manual insertion of the tubular sampler into the river sediment or use a hammer to drive the tubular sampler into the river sediment for sampling and collection operations. Although this method can meet normal sampling and detection needs, it is labor-intensive and inconvenient to use. In addition, due to the influence of climate and topography, the fluidity of the river bottom is strong. When the sampling tube is pulled out of the river, other substances may flow into the tube body, reducing the accuracy of the sampling detection. When personnel manually pull out the sampling tube, shaking is likely to occur, which may cause part of the sample to fall out of the sampling tube, and the integrity of the river sediment sampling cannot be ensured. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a river bottom mud sampler which realizes convenient sampling operation by manually controlling the movement of a sliding rod and cooperating with a tooth groove to drive a rotating arm and a bucket to dig.

[0005] The utility model is achieved through the following technical scheme: the utility model proposes a river sediment sampler, including a casing, a sleeve fixedly mounted on the casing, a travel cavity opened in the sleeve, a slide rod slidably connected in the travel cavity, a gear seat formed at the lower end of the slide rod, a rotating shaft fixedly mounted on both sides of the gear seat in the casing, there are two rotating shafts, both of which are rotatably connected to a rotating arm, the rotating arms are symmetrically distributed, one end of the rotating arm adjacent to the gear seat is formed with a tooth groove, the tooth groove is meshed with the gear seat, and a bucket is fixedly mounted on the other end of the rotating arm.

[0006] By adopting the above technical solution, the tooth seat can drive the rotating arm to rotate through the tooth groove, and the tooth groove can ensure a constant and stable transmission ratio between the two through meshing with the tooth seat. The rotating shaft can provide stable support and positioning for the movement of the rotating arm, thereby ensuring stable operation of the tooth groove and the rotating arm.

[0007] Furthermore, a handle is fixedly mounted on one end of the sleeve, and the handle is in a J-shaped structure.

[0008] By adopting the above technical solution, the functions of holding and controlling can be provided to the staff, making it convenient for the staff to move the sleeve.

[0009] Furthermore, the handle is covered with an anti-slip cover, the anti-slip cover is a rubber cover, and the surface of the anti-slip cover is provided with anti-slip patterns.

[0010] By adopting the above technical solution, the staff can hold the handle more comfortably and provide an anti-slip and stable effect.

[0011] Furthermore, a driving motor is fixedly installed at the top of the stroke cavity, a transmission output end of the driving motor is fixedly connected to a threaded rod, a threaded cavity is opened at the connection between the sliding rod and the threaded rod, and the threaded rod is meshed with the threaded cavity.

[0012] By adopting the above technical solution, the driving motor can drive the threaded rod to perform rotational motion, so that the threaded rod can drive the sliding rod to perform lifting motion under the meshing action with the threaded cavity.

[0013] Furthermore, sliding rails are provided on both end walls of the sliding rod, and sliding blocks are formed in the sleeve at positions corresponding to the sliding rails. The sliding blocks match the specifications of the sliding rails and are slidably connected.

[0014] By adopting the above technical solution, the sliding connection relationship between the slider and the slide rail can provide a horizontal limiting effect for the slide bar, thereby ensuring smooth and stable vertical lifting and lowering movement of the slide bar.

[0015] Furthermore, the lower end of the bucket is formed with digging teeth, and the bucket is formed with biting grooves at the intersections of the digging teeth, and the digging teeth match the specifications of the biting grooves.

[0016] By adopting the above technical solution, the bucket can be closed more tightly when it is gathered and closed from both sides to the middle, and the digging teeth can reduce the resistance generated by the bucket during the digging operation, thereby improving the overall operation efficiency.

[0017] Furthermore, the bucket is a steel bucket, and a mud storage tank is formed inside the bucket.

[0018] By adopting the above technical solution, the bucket can be made wear-resistant and corrosion-resistant, thereby extending the overall service life, and the mud storage tank can accommodate the river bottom mud excavated by the bucket.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The utility model provides a convenient sampling mechanism consisting of a casing, a sleeve, a sliding rod, a gear seat, a rotating arm, a rotating shaft, a tooth groove, a bucket, a driving motor, a threaded rod and a slider.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] like Figure 1-Figure 3As shown, a river sediment sampler in this embodiment includes a casing 1, a sleeve 2 is fixedly installed on the casing 1, a stroke chamber 3 is opened in the sleeve 2, a slide rod 4 is slidably connected in the stroke chamber 3, a gear seat 7 is formed at the lower end of the slide rod 4, a rotating shaft 9 is fixedly installed on both sides of the gear seat 7 in the casing 1, there are two rotating shafts 9, and a rotating arm 8 is rotatably connected to the rotating shaft 9. The rotating arms 8 are symmetrically distributed, and tooth grooves 10 are formed at one end of the rotating arm 8 adjacent to the gear seat 7, and the tooth grooves 10 are meshed with the gear seat 7. A bucket 11 is fixedly installed on the other end of the rotating arm 8. The movement of the gear seat 7 can provide power for the opening and closing of the rotating arm 8 through the tooth grooves 10, ensuring that the rotating arm 8 can drive the bucket 11 to perform stable digging operations, and the rotating shaft 9 can maintain stable performance during operation. At the same time, it can provide a certain bearing capacity for the movement of the rotating arm 8, ensuring that the overall operation is more stable.

[0030] like Figure 1-Figure 3 As described, a handle 5 is fixedly mounted at one end of the sleeve 2, and the handle 5 is in a J-shaped structure. An anti-skid cover 6 is sleeved on the handle 5, and the anti-skid cover 6 is a rubber cover, and the surface of the anti-skid cover 6 is provided with anti-skid patterns. The handle 5 can make it more convenient for the staff to move the sleeve 2. The anti-skid cover 6 has a certain elasticity, which can increase the comfort of the staff when holding it. After the surface is treated with anti-skid patterns, the friction can be increased to prevent slipping, so that the staff can hold it more stably and improve the aesthetics.

[0031] like Figure 2 , Figure 4 and Figure 5 As described, a driving motor 14 is fixedly installed at the top of the stroke cavity 3, and a threaded rod 15 is fixedly connected to the transmission output end of the driving motor 14. A threaded cavity 16 is provided at the connection between the slide rod 4 and the threaded rod 15, and the threaded rod 15 is meshed with the threaded cavity 16. The threaded rod 15 can rotate under the drive of the driving motor 14, and drive the slide rod 4 to be raised and lowered through the threaded cavity 16; slide rails 17 are provided on the two end walls of the slide rod 4, and sliders 18 are formed at the corresponding positions of the sleeve 2 with the slide rails 17. The sliders 18 match the specifications of the slide rails 17 and are slidably connected to ensure the stability of the displacement adjustment operation of the slide rod 4.

[0032] like Figure 3-Figure 5As shown, the lower end of the bucket 11 is formed with digging teeth 12, and the bucket 11 is formed with biting grooves 13 at the intersection of the digging teeth 12. The specifications of the digging teeth 12 and the biting grooves 13 match each other. The lower end of the bucket 11 is formed with digging teeth 12, and the specifications of the digging teeth 12 and the biting grooves 13 match each other, which can ensure that the river sediment samples dug from the mud storage tank are not easy to fall when the bucket 11 gathers and closes from both sides, thereby ensuring the integrity of the river sediment samples and improving the accuracy of sample detection; the bucket 11 is a steel bucket, and a mud storage tank is formed inside the bucket 11. The bucket 11 is made of high-strength steel, which can make the bucket 11 have better digging performance, higher operating efficiency, and more wear resistance, thereby increasing the overall service life.

[0033] The specific implementation process of this embodiment is as follows: when in use, the staff moves the river sediment sampler to a suitable position through the handle 5, and then starts the drive motor 14 to drive the threaded rod 15 to rotate forward, so that the threaded rod 15 can drive the slide bar 4 to move downward in the stroke cavity 3 under the meshing action with the threaded cavity 16, and the tooth seat 7 drives the rotating arm 8 to rotate around the rotating shaft 9 as the axis through the tooth groove 10, and drives the bucket 11 to open to both sides at the same time, and then the staff can put the bucket 11 into the river sediment, and hold the sleeve 2 through the handle 5, and then start the drive motor 14 again to drive the threaded rod 15 to rotate in the opposite direction, so that the threaded rod 15 can drive the slide bar 4 to move upward in the stroke cavity 3 under the meshing action with the threaded cavity 16, and drive the gear seat 7 to move upward in the stroke cavity 3. The seat 7 moves upward, and at the same time, the tooth groove 10 drives the rotating arm 8 to rotate around the rotating shaft 9 as the axis, so that the symmetrically distributed buckets 11 can gather and close in the middle, and the river bottom mud located in the middle of the buckets 11 on both sides can be dug into the bucket 11 and sealed. At this time, the integrity of the river bottom mud sample can be ensured, and then the bucket 11 is taken out of the river and moved to the sample placement area, and the screw rod is driven to rotate forward by the driving motor 14 again, so that the slide bar 4 and the tooth seat 7 move downward again and drive the rotating arm 8 to rotate through the tooth groove 10, so that the bucket 11 opens to both sides, so that the river bottom mud can flow out, and a complete river bottom mud sample can be obtained. The opening degree of the bucket 11 can be controlled by controlling the lifting degree of the slide bar 4, so as to control the extraction amount of the river bottom mud sample.
