Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a simple sleeve-type device suitable for fertilizer sampling. Background Technology

[0002] A fertilizer sampler is a specialized tool used to obtain representative samples from fertilizer piles, packaging, or transport vehicles. A sampling probe is a common solid fertilizer sampler, made of stainless steel or electroplated copper tubing, approximately 65cm in total length, with a 60cm long and 1.2cm wide slot and an inner diameter of 1.6cm. One end is fitted with a metal or straight wooden handle, and the other end is ground at a 30-degree angle for insertion into the fertilizer pile or packaging for sampling.

[0003] However, because one end of the sampling probe is designed with a sharp point that is easy to pierce, and the sampling device lacks a protective device when not in use, the sharp point of the sampling probe can easily injure staff or damage items when operation is inconvenient, posing a significant safety hazard.

[0004] Therefore, a sampling device that can improve the safety of the sampling probe is needed. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a simple sleeve-type device suitable for fertilizer sampling. The sleeve slides on the handle via a groove, allowing it to wrap around the sampling tube when the sampling device is not in use. A fastening mechanism secures the sleeve and handle, preventing the sleeve from failing to wrap around the sampling tube and thus avoiding accidental injury to workers or objects when the sampling device is not in use, thereby increasing the safety of the sampling device.

[0006] This utility model is achieved through the following technical solution: a simple sleeve-type device suitable for fertilizer sampling is provided, including a handle with a sampling tube fixed on it; a groove extending axially along the sampling tube is provided on the handle, and a sleeve is slidably placed in the groove, the sleeve being fitted onto the sampling tube, and the sleeve being connected to the handle through a fastening mechanism; the sleeve slides on the handle through the groove, thereby allowing the sleeve to wrap around the sampling tube when the sampling device is not in use, and the fastening mechanism secures the sleeve and the handle, preventing the sleeve from failing to wrap around the sampling tube, thus preventing the sampling tube from accidentally injuring personnel or objects when the sampling device is not in use, and increasing the safety of the sampling device.

[0007] As an optimization, the handle is provided with multiple sleeves that slide in sequence; by reducing the length of the handle through multiple sleeves that retract in sequence, the size of the sampling device is reduced, resulting in a simple structure that is easy to carry.

[0008] As an optimization, a limiting ring A is provided on the inner side of the chute and the end of the sleeve near the sampling end of the sampling tube, and a limiting ring B that matches the limiting ring A is provided on the outer side of the end of the sleeve away from the sampling end of the sampling tube; the limiting ring A and the limiting ring B prevent the handle and the sleeve from detaching from each other.

[0009] As an optimization, the fastening mechanism includes an internal thread on the limiting ring A and an external thread on the limiting ring B, and the external thread and the internal thread are compatible; the external thread and the internal thread facilitate the fastening of the handle and the sleeve to each other.

[0010] As an optimization, the internal thread is located at the end of the limiting ring A away from the sampling end of the sampling tube; to prevent the external thread and the internal thread from separating from each other.

[0011] As an optimization, a flexible baffle is provided inside the sleeve near the sampling tube, and the baffle is located at the end of the sleeve near the sampling end of the sampling tube; the flexible baffle prevents foreign objects from entering the sleeve.

[0012] As an optimization, the outer side of the cannula and handle near the sampling tube is provided with anti-slip texture; the anti-slip texture facilitates the rotation of the handle and cannula.

[0013] As an optimization, the inner cavity of the sampling tube extends through the handle, and the end of the handle away from the sampling tube is provided with a cap that fits the inner cavity of the sampling tube; the sampling tube extending through the handle prevents fertilizer residue from remaining in the sampling tube, and the cap prevents fertilizer samples from spilling out of the sampling tube.

[0014] The beneficial effects of this utility model are as follows: the sleeve slides on the handle through the sliding groove, so that the sleeve wraps around the sampling tube when the sampling device is idle, and the sleeve and handle are fastened by the fastening mechanism to prevent the sleeve from failing to wrap the sampling tube, thereby preventing the sampling tube from accidentally injuring staff or objects when the sampling device is idle, and increasing the safety of the sampling device.
