Description

Technical Field

[0001] The utility model relates to the technical field of soil remediation, in particular to an adjustable sample collection device. Background Art

[0002] The collection of soil samples is an important part of soil remediation work, and the collection of soil samples requires the use of a sample collection device.

[0003] After searching, the patent specification with the authorization announcement number CN217687951U proposes an adjustable sample collection device for soil remediation, which specifically relates to the field of soil remediation technology, including a fixed box, the bottom of which is rotatably connected to a plurality of fixed barrels, the bottoms of the plurality of fixed barrels are fixedly connected to sampling barrels, the bottoms of the plurality of sampling barrels are fixedly connected to sampling knives, a sampling assembly is provided inside the fixed box, the bottom of the fixed box and the upper surfaces of the plurality of sampling barrels are provided with positioning holes, the interiors of the plurality of positioning holes are provided with positioning assemblies, and the interiors of the plurality of sampling barrels are provided with sampling grooves. After removing the positioning assembly, this patented technology drives the rotation of the plurality of fixed barrels through the driving assembly, and the plurality of fixed barrels drives the rotation of the sampling barrels. The rotation of the plurality of sampling barrels can rotate and sample the ground, and then the sampling barrels are pushed by the electric push rod, so that the sampling barrels that have completed the sampling slide up and away from the ground, thereby completing the sampling. The following problems exist in this technical solution:

[0004] During use, soil within the same range can be sampled by raising and lowering multiple sampling tubes and sampling knives. Since the heights of the multiple sampling tubes and sampling knives are equal each time, and it is inconvenient to control each sampling tube and sampling knife individually, when the flatness of the ground in the same range is different, some sampling tubes and sampling knives will not be able to sample the soil, further reducing the sampling effect. Utility Model Content

[0005] In view of the above-mentioned technical problems and the shortcomings in the field, the utility model provides an adjustable sample collection device, which can control each sampling tube and sampling knife individually, and adjust the height of each sampling tube and sampling knife. Even if the ground flatness is different in the same range, it can still ensure that each sampling tube and sampling knife can collect soil, thereby improving the sampling effect.

[0006] The specific technical solutions are as follows:

[0007] An adjustable sample collection device includes a fixed cylinder;

[0008] One or more electric telescopic rods are fixedly installed on the top of the fixed cylinder, and the output end of each electric telescopic rod passes through the top side of the fixed cylinder and extends to the interior of the fixed cylinder. A mounting cylinder is fixedly installed on the output end of the electric telescopic rod, and a motor is fixedly installed inside the mounting cylinder. A sampling cylinder is fixedly installed on the output end of the motor through a coupling, and a sampling knife is fixedly installed on the bottom end of the sampling cylinder.

[0009] When the above-mentioned adjustable sample collection device is in use, when it is necessary to sample the soil on the ground, the motor inside the mounting tube is turned on and the motor drives the sampling tube fixed at the output end to rotate, and the sampling tube can drive the sampling knife fixed at the bottom end to rotate. At the same time, the electric telescopic rod is turned on and the electric telescopic rod can drive the output end mounting tube and its internal components, such as the motor and the sampling tube, to move up and down to adjust, thereby meeting the needs of collecting soil samples at different heights and depths.

[0010] In some embodiments, the adjustable sample collection device may further include a protective mechanism, which is disposed on the fixed tube and is used to shield and protect the electric telescopic rod. Furthermore, the protective mechanism may include an internally threaded tube, which is fixedly disposed on the top of the fixed tube, and the internal threads of the internally threaded tube are connected to a threaded rod, and a protective cover for shielding and protecting the electric telescopic rod is fixedly disposed on the top of the threaded rod. The threaded rod is threadedly connected to the internally threaded tube fixed on the fixed tube, and the protective cover fixed on the top of the threaded rod can be threadedly installed on the fixed tube by rotating the threaded rod. At the same time, the height of the protective cover can also be adjusted, thereby achieving the effect of shielding or exposing the electric telescopic rod, achieving the effect of protection, avoiding the normal operation affected by external dust and debris, facilitating use and maintenance, and improving convenience.

[0011] In some embodiments, the adjustable sample collection device may further include a shock absorbing mechanism, which is disposed at the bottom of the fixed cylinder and is used to provide buffering and shock absorption for the fixed cylinder. Furthermore, the shock absorbing mechanism may include a fixed ring, which is fixedly disposed on the outer wall of the fixed cylinder, and the bottom of the fixed ring is symmetrically fixed with supporting legs, each supporting leg is provided with a buffer cylinder at the bottom end, and a moving wheel is fixedly installed at the bottom of the buffer cylinder. The design of the moving wheel facilitates the movement and transportation of the entire device.

[0012] In one embodiment, the adjustable sample collection device has a buffer plate slidably connected to the inside of the buffer tube, the bottom end of the support leg is fixed to the top side of the buffer plate, a damping buffer is fixedly arranged on the bottom side of the buffer plate, and the damping buffer is fixedly arranged on the bottom side of the inner wall of the buffer tube. During the movement of the device, the support leg fixed at the bottom of the fixed ring will drive the buffer plate to slide in the buffer tube, and the buffer plate will press down the damping buffer, and the sliding of the buffer plate can be damped and buffered by the damping buffer, reducing vibration and impact, achieving the effect of buffering and shock absorption, and improving the stability of the device during movement.

[0013] In one embodiment, the adjustable sample collection device may have one or more push handles fixedly disposed on the top of the fixed ring. The push handles on the top of the fixed ring provide a convenient handle for operation, so that the staff can hold the push handles to move the entire device and adjust its position.

[0014] In one embodiment, the adjustable sample collection device may have one or more heat dissipation holes on the top of the mounting tube. The heat dissipation holes on the top of the mounting tube help to dissipate the heat generated by the motor during operation and maintain the normal operation of the motor.

[0015] In one embodiment, in the adjustable sample collection device, a slider can be fixedly provided on the outer wall of the mounting tube, and a slide groove for sliding connection of the slider is provided on the inner wall of the fixed tube. The slider on the outer wall of the mounting tube cooperates with the slide groove on the inner wall of the fixed tube to ensure that the mounting tube can move up and down smoothly under the drive of the electric telescopic rod. When there are multiple electric telescopic rods and mounting tubes, since each mounting tube corresponds to a corresponding electric telescopic rod, the height of each sampling tube and sampling knife can be individually controlled to rise and fall, so as to avoid the phenomenon that some sampling tubes and sampling knives cannot collect soil when the ground flatness is different in the same range, thereby improving the sampling effect.

[0016] In one embodiment, the adjustable sample collection device has a push plate slidably connected to the interior of the sampling tube, one or more push rods are fixedly arranged on the outer wall of the push plate, and a limit groove for the corresponding push rod to slide and limit is opened on the outer wall of the sampling tube. Through the rotational cooperation of the sampling tube and the sampling knife, the sample can be cut and collected, and the collected soil sample will push the push plate and remain in the sampling tube. Since the limit groove on the outer wall of the sampling tube is small, the sample collected is difficult to leak out of the limit groove. Finally, the push rod fixed on the outer wall of the push plate is pushed to drive the push plate to push out the sample in the sampling tube, which is convenient for collection and processing, and the push rod will slide in the limit groove, which is conducive to playing a limiting role.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. Through the arrangement of electric telescopic rod, mounting tube, slider, slide slot and motor, the height of each sampling tube and sampling knife can be individually controlled, which further improves the sampling effect.

[0019] 2. The protective mechanism can be used to shield or expose the electric telescopic rod, thereby achieving a protective effect and preventing normal operation from being affected by external dust and debris, making it easier to use and maintain and improving convenience.

[0020] 3. The damping mechanism can damp and buffer the sliding of the buffer plate, reduce vibration and impact, achieve the effect of buffering and shock absorption, and improve the stability of the device when moving.

[0021] 4. The height of each sampling tube and sampling knife can be controlled individually to avoid the phenomenon that some sampling tubes and sampling knives cannot collect soil when the ground flatness is different in the same range, which further improves the sampling effect.

At the same time, the electric telescopic rod 2 is opened for operation, and the electric telescopic rod 2 can drive the mounting cylinder 3 at the output end and its internal components, such as the motor 4 and the sampling cylinder 5, to move up and down and adjust, so as to meet the sample collection requirements of different heights and depths. By coordinating with the rotation of the sampling cylinder 5 and the sampling knife 6, the samples can be cut and collected, and the collected samples will remain in the sampling cylinder 5.

[0030] A protective mechanism is arranged on the fixed cylinder 1 for shielding and protecting a plurality of electric telescopic rods 2. The protective mechanism comprises an internally threaded cylinder 19, which is fixedly arranged on the top of the fixed cylinder 1. A threaded rod 20 is connected to the internal thread of the internally threaded cylinder 19. A protective cover 21 for shielding and protecting the electric telescopic rod 2 is fixedly arranged on the top of the threaded rod 20. The threaded rod 20 is threadedly connected to the internally threaded cylinder 19 fixed on the fixed cylinder 1, and the threaded rod 20 is rotated to thread the protective cover 21 fixed on the top of the threaded rod 20 to the fixed cylinder 1. At the same time, the height of the protective cover 21 can also be adjusted, thereby realizing the shielding or exposing effect of the electric telescopic rod 2, achieving the protective effect, avoiding the normal operation affected by external dust and debris, facilitating use and maintenance, and improving convenience.

[0031] A shock absorbing mechanism is arranged at the bottom of the fixed cylinder 1 for buffering and shock absorbing the fixed cylinder 1. The shock absorbing mechanism includes a fixed ring 13, which is fixedly arranged on the outer wall of the fixed cylinder 1. The bottom of the fixed ring 13 is symmetrically fixed with support legs 14 in pairs. A buffer cylinder 15 is arranged at the bottom end of each support leg 14. A moving wheel 16 is fixedly installed at the bottom of the buffer cylinder 15. A buffer plate 17 is slidably connected to the inside of the buffer cylinder 15.

The heat dissipation holes 11 opened on the top of the mounting tube 3 are helpful for dissipating the heat generated by the motor 4 during work and maintaining the normal operation of the motor 4. The slider 12 on the outer wall of the mounting tube 3 cooperates with the slide groove on the inner wall of the fixed tube 1 to ensure that the mounting tube 3 can move up and down smoothly under the drive of the electric telescopic rod 2.
