Description

Technical Field

[0001] This patent relates to the technical field of sample extraction, and specifically to a sampling device based on organic fertilizer fermentation. Background Art

[0002] During the process of the fertilizer piling up and decomposing in the fermentation tank, it is necessary to understand the decomposition situation of the fertilizer at any time. In addition to observing the temperature inside the fertilizer pile, it is also necessary to monitor various technical indicators of the fertilizer at any time, such as the contents of nitrogen, phosphorus, potassium, organic matter, pH value, moisture, etc.

[0003] A sampling device based on organic fertilizer fermentation proposed in the existing CN218956189U uses a cylindrical box body that can be sealed by a conical sealing plug for sampling. During the process of inserting or pulling out, the conical sealing plug can seal the cylindrical box body, thereby preventing external fertilizers from entering and achieving the purpose of layered sampling.

[0004] However, since the organic fertilizer is solid and not in a loose state in the fermentation barrel, when this sampling device is inserted, it will press the upper-layer fertilizer into the inner layer, resulting in the inability to determine the original layer of the taken sample and causing a large error in the final test result. Utility Model Content

[0005] The purpose of this patent is to provide a solution to the problems raised in the above background art.

[0006] To achieve the above purpose, this patent provides the following technical solution: A sampling device based on organic fertilizer fermentation includes a sampling cylinder and a pressure rod.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present patent will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present patent. Obviously, the described embodiments are only a part of the embodiments of the present patent, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present patent without creative efforts shall fall within the protection scope of the present patent.

[0021] Please refer to Figures 1-3 , the present patent provides a technical solution: a sampling device based on organic fertilizer fermentation, including a sampling cylinder 1 and a pressure rod 2. The pressure rod 2 is installed on the upper wall of the sampling cylinder 1, and a fixing ring 3 is sleeved outside the pressure rod 2;

[0022] When sampling, the pressure rod 2 can be rotated to drive the sampling cylinder 1 to rotate and screw into the organic fertilizer, so that the organic fertilizer enters the sampling cylinder 1;

[0023] By the rotation method, the oppression of the device on the organic fertilizer can be effectively reduced, thus avoiding the stratification disorder of the organic fertilizer during the pressing process and affecting the later test results;

[0024] The sampling cylinder 1 includes a main cylinder body 11, a sub-cylinder body 12, a chute 13, a convex block 14, a positioning hole 15 and a positioning pin 16. The cross-sections of the main cylinder body 11 and the sub-cylinder body 12 are both semi-circular. A chute 13 is opened on the side wall of the main cylinder body 11, a convex block 14 is installed on the side wall of the sub-cylinder body 12, the convex block 14 can slide into and be installed in the chute 13, a positioning pin 16 is installed on the side wall of the main cylinder body 11, a positioning hole 15 is opened on the side wall of the sub-cylinder body 12, and the positioning pin 16 can be inserted and installed in the positioning hole 15;

[0025] In this article, the sampling cylinder 1 is composed of the main cylinder body 11 and the sub-cylinder body 12, making it more convenient to take out the fertilizer in the sampling cylinder 1 later, and at the same time, it will not cause oppression to the fertilizer in the sampling cylinder 1 and affect the stratification of the internal fertilizer;

[0026] In addition, after separating the main cylinder body 11 and the sub-cylinder body 12, the entire inner cavity of the sampling cylinder 1 is exposed, which is convenient for cleaning its inner wall and avoiding fertilizer residue inside, affecting the next sampling;

[0027] A connection hole 4 is opened on the upper wall of the main cylinder body 11, a piston mechanism 5 is installed on the lower wall of the fixing ring 3, and the piston mechanism 5 is inserted and installed in the sampling cylinder 1 through the connection hole 4;

[0028] By setting the piston mechanism 5, the organic fertilizer can be sucked upward to avoid the internal fertilizer from falling. At the same time, during the movement of the piston mechanism 5, the inner wall of the sampling cylinder 1 can be scraped to scrape off the residual fertilizer on the inner wall.

[0029] Specifically, a sliding ring 6 is rotatably installed on the outer side of the pressure rod 2. One end of a connecting rod 7 is installed on the lower wall of the sliding ring 6, and the other end of the connecting rod 7 is installed on the upper wall of the fixed ring 3. A pull rod 8 is installed on the side wall of the sliding ring 6.

[0030] Specifically, the piston mechanism 5 includes a piston rod 51, a clamping block 52, a piston plate 53, an installation groove 54 and a buckle 55. One end of the piston rod 51 is installed on the lower wall of the fixed ring 3, and the other end of the piston rod 51 passes through the upper wall of the main cylinder body 11 through a connection hole 4 and is installed with a clamping block 52. An installation groove 54 is formed on the upper wall of the piston plate 53, and a buckle 55 is installed on the inner wall of the installation groove 54. The clamping block 52 can be inserted into the installation groove 54, and the buckle 55 can fix the clamping block 52.

[0031] Since the piston plate 53 needs to rub against the inner wall of the sampling cylinder 1 many times, it is prone to wear, resulting in piston failure. Therefore, in this device, the piston plate 53 is set to be detachable so that it can be replaced separately, saving costs.

[0032] Specifically, an anti-slip grip sleeve 9 is sleeved on the outer side of the end of the pressure rod 2 away from the sampling cylinder 1, and anti-slip patterns 10 are provided on the outer sides of both the anti-slip grip sleeve 9 and the pull rod 8.

[0033] Specifically, a sealing gasket 17 is fitted and installed on the lower wall of the convex block 14, and the sealing gasket 17 can be fitted with the inner wall of the sliding groove 13.

[0034] By providing the sealing gasket 17, it is possible to prevent organic fertilizer from entering the sliding groove 13 and avoid affecting the separation and installation of the main cylinder body 11 and the sub-cylinder body 12.

[0035] Specifically, a convex plate 18 is provided on the outer wall of the sampling cylinder 1, and the convex plate 18 is spirally arranged on the outer wall of the sampling cylinder 1.

[0036] Working principle: When sampling, first place the sampling cylinder 1 on the organic fertilizer, and then drive the sampling cylinder 1 to rotate through the pressure rod 2. Under the action of the convex plate 18, the sampling cylinder 1 is screwed into the organic fertilizer, and its interior will also be filled with organic fertilizer. During the screwing process, the staff needs to pull the sliding ring 6 upward through the pull rod 8 to prevent the piston plate 53 from pressing on the organic fertilizer. After sampling, screw the sampling cylinder 1 out of the fertilizer, and then the positioning pin 16 can be pulled out of the positioning hole 15, and then the sub-cylinder body 12 can be removed from the main cylinder body 11, so that the fertilizer inside the sampling cylinder 1 is exposed, facilitating the taking and testing of the fertilizer.

[0037] Sampling the fertilizer through this device can avoid the stratification and chaos of the fertilizer, affecting the later test results.
