Description

Technical Field

[0001] This utility model relates to the field of soil and water monitoring technology, and in particular to a continuous sampling machine for soil and water conservation monitoring. Background Technology

[0002] Soil and water conservation refers to the preventive and control measures taken against soil erosion caused by natural factors and human activities. It is the work of preventing and controlling soil erosion, protecting, improving and rationally utilizing soil and water resources, and establishing a good ecological environment. It uses comprehensive measures such as agriculture, forestry, animal husbandry and water conservancy, such as building terraces, closing mountains for afforestation, and building ponds and dams, to conserve water sources, reduce surface runoff, increase ground cover and prevent soil erosion. It is of great significance for the development of production and construction in hilly and wind-blown sandy areas, reducing downstream riverbed siltation, reducing flood peaks, ensuring the normal operation of water conservancy facilities and ensuring transportation, industrial and mining construction and urban safety. In the process of soil and water conservation, it is necessary to use sampling devices to sample and monitor soil and water.

[0003] A search of Chinese Patent Publication No. CN219200950U reveals a continuous sampling machine for soil and water conservation monitoring, comprising a base and a sampling cup. A rotating disk is rotatably mounted inside the base, and a fixed cylinder is fixedly connected to the bottom of the rotating disk via screws. A shaped block is fixedly connected to the bottom of the base via screws, and a sampling cup is fixedly connected to one side of the shaped block via screws. A servo motor is mounted on the top of the sampling cup, and the output end of the servo motor is connected to a rotating rod via a coupling. Spiral blades are mounted on the outer circumference of the rotating rod, and a discharge pipe is mounted on the outer circumference of the sampling cup. When the sampling cup is inserted into the muddy ground to be sampled, the servo motor is started, driving the rotating rod to rotate. The rotation of the rotating rod drives the spiral blades to rotate, thus sampling the muddy ground. Simultaneously, the rotating disk drives the sampling cup to rotate intermittently, achieving continuous sampling.

[0004] In the aforementioned patent, during the process of the rotating disk driving the sampling cup to rotate, the mud and water remaining in the sampling cylinder and discharge pipe may flow into the gap between two adjacent sampling cups of the rotating disk, which is inconvenient for later cleaning. Utility Model Content

[0005] The purpose of this invention is to provide a continuous sampling machine for soil and water conservation monitoring in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A continuous sampling machine for soil and water conservation monitoring includes a base with a mounting hole at the top. A sampling cylinder, penetrating the base, is fixedly connected to the mounting hole. A sampling mechanism is installed inside the sampling cylinder. Several circumferentially arranged grooves are formed at the top of the base, and sampling cups are placed in the grooves. A discharge mechanism is provided outside the sampling cylinder. The discharge mechanism includes a sampling hole. Several circumferentially arranged sampling holes are formed on the inner wall of the sampling cylinder, penetrating the sampling cylinder. A collar is rotatably connected to the outer wall of the sampling cylinder. A discharge pipe is fixedly connected to the outer wall of the collar, and the discharge pipe is located above the sampling cup. A discharge hole communicating with the discharge pipe is formed on the inner wall of the collar. The height and diameter of the discharge hole are the same as those of the sampling hole. The discharge mechanism also includes a power component for driving the collar to rotate. A receiving component is provided outside the collar, located below the discharge pipe.

[0008] Preferably, the power assembly includes a gear ring fixedly connected to the outer wall of the collar, a horizontal plate fixedly connected to the outer wall of the sampling cylinder, a stepper motor fixedly connected to the top of the horizontal plate, and a gear fixedly connected to the output end of the stepper motor, the gear meshing with the gear ring.

[0009] Preferably, the receiving assembly includes a mounting bracket fixedly connected to the outer wall of the collar, a hydraulic cylinder fixedly connected to the side of the mounting bracket away from the collar, a receiving box fixedly connected to the output end of the hydraulic cylinder, and the receiving box slidably connected between the inner walls of the mounting bracket.

[0010] Preferably, the mounting frame is U-shaped with the opening facing the collar, and the discharge pipe is located in the middle of the mounting frame.

[0011] Preferably, the bottom of the sampling tube is open.

[0012] Preferably, the sampling mechanism includes a rotary motor fixedly connected to the top of the sampling cylinder, the output end of the rotary motor is connected to a rotary shaft via a coupling, the rotary shaft extends into the sampling cylinder, and a helical blade is fixedly connected to the outer wall of the rotary shaft.

[0013] The beneficial effects are as follows: when the collar is driven to rotate by the power component, the discharge port and the sampling port are misaligned, so that the mud and water in the sampling tube will not continue to flow out. At the same time, the mud and water remaining in the discharge pipe are caught by the receiving component, preventing the mud and water from flowing into areas outside the sampling cup, which would be inconvenient for later cleaning.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5As shown, a continuous sampling machine for soil and water conservation monitoring includes a base 1. The top of the base 1 has an installation hole, and a sampling cylinder 2 that penetrates the base 1 is fixedly connected in the installation hole. The bottom of the sampling cylinder 2 is open, and a sampling mechanism is provided inside the sampling cylinder 2. The sampling mechanism includes a rotary motor 301 bolted to the top of the sampling cylinder 2. The output end of the rotary motor 301 is connected to a rotary shaft 302 through a coupling. The rotary shaft 302 extends into the sampling cylinder 2, and a spiral blade 303 is fixedly connected to the outer wall of the rotary shaft 302. When the rotary motor 301 is started, the rotary motor 301 drives the rotary shaft 302 to rotate the spiral blade 303, continuously transporting mud and water from the bottom end of the sampling cylinder 2 to the top end of the sampling cylinder 2, thereby achieving continuous sampling.

[0026] The top of the base 1 has several circumferentially arranged grooves, and the sampling cup 4 is placed in the grooves.

[0027] The sampling cylinder 2 is equipped with a discharge mechanism, which includes a sampling hole 501. The inner wall of the sampling cylinder 2 has several circumferentially arranged sampling holes 501, one sampling hole 501 corresponds to one sampling cup 4, and the sampling hole 501 passes through the sampling cylinder 2. The outer wall of the sampling cylinder 2 is rotatably connected to a collar 502, and the outer wall of the collar 502 is fixedly connected to a discharge pipe 503. The discharge pipe 503 is located above the sampling cup 4. The inner wall of the collar 502 has a discharge hole 504 that communicates with the discharge pipe 503. The height and diameter of the discharge hole 504 are the same as those of the sampling hole 501. When the discharge hole 504 corresponds to the sampling hole 501, the mud and water in the sampling cylinder 2 can flow out. When the discharge hole 504 is misaligned with the sampling hole 501, the mud and water in the sampling cylinder 2 cannot flow out.

[0028] The discharge mechanism also includes a power component, which drives the collar 502 to rotate. The power component includes a gear ring 505 fixedly connected to the outer wall of the collar 502. A horizontal plate 506 is bolted to the outer wall of the sampling cylinder 2. A stepper motor 507 is bolted to the top of the horizontal plate 506. A gear 508 is fixedly connected to the output end of the stepper motor 507. The gear 508 meshes with the gear ring 505. When the stepper motor 507 is started, the stepper motor 507 drives the gear 508 to rotate. The gear 508 meshes with the gear ring 505, thereby driving the gear ring 505 to rotate the collar 502 by a certain angle, rotating the discharge pipe 503 directly above the adjacent sampling cup 4.

[0029] A receiving assembly is provided on the outside of the collar 502. The receiving assembly is located below the discharge pipe 503. The receiving assembly includes a mounting bracket 601 bolted to the outer wall of the collar 502. The mounting bracket 601 is U-shaped with its opening facing the collar 502. The discharge pipe 503 is located in the middle of the mounting bracket 601. A hydraulic cylinder 602 is fixedly connected to the side of the mounting bracket 601 away from the collar 502. The output end of the hydraulic cylinder 602 is fixedly connected to a mounting plate. A receiving box 603 is bolted to the other side of the mounting plate. The receiving box 603 is slidably connected between the inner walls of the mounting bracket 601.

[0030] Working principle: In use, the sampling cylinder 2 is inserted into the muddy ground to be sampled. The rotary motor 301 is started, which drives the rotary shaft 302 to rotate the spiral blades 303, continuously transporting the muddy water from the bottom to the top of the sampling cylinder 2. Then, it enters the discharge pipe 503 through the sampling hole 501 and the discharge hole 504, and flows into the sampling cup 4 for collection, thus achieving continuous sampling. When the sampling cup 4 has collected the required amount, the rotary motor 301 is turned off. Then, the stepper motor 507 is started, which drives the gear 508 to rotate. The gear 508 meshes with the gear ring 505, thereby driving the gear ring 505 to rotate the collar 502 and the discharge pipe 503. At this time, the discharge hole 504 on the collar 502 is misaligned with the sampling hole 501, so that the muddy water in the sampling cylinder 2 will not continue to flow out. Before the collar 502 starts to rotate, the receiving box 603 is moved directly below the discharge pipe 503 by the hydraulic cylinder 602. The receiving box 603 catches the residual mud and water in the discharge pipe 503 to prevent the mud and water from flowing into areas other than the sampling cup 4, which would make it inconvenient for later cleaning. After the discharge pipe 503 is rotated directly above the adjacent sampling cup 4, the stepper motor 507 stops rotating. The discharge hole 504 on the collar 502 corresponds to the sampling hole 501 on the sampling cylinder 2. Then, the receiving box 603 is moved away by controlling the hydraulic cylinder 602 to continue sampling.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
