[0002] In police dog crime scene investigations, especially homicide scenes, complex cases often arise involving buried, dismembered, missing, or abandoned bodies, as well as cases buried for years without being discovered. However, traditional methods used for police dog training and crime scene investigation have many shortcomings.

[0003] Currently, most methods involve manual excavation, using tools such as shovels, excavators, Luoyang shovels, and steel bars. These methods are time-consuming, labor-intensive, and expensive. Specifically, shovel excavation training requires a large number of personnel for digging and burying, causing significant soil damage and potentially leading to an overly strong smell of fresh soil that could mislead police dogs. Furthermore, incomplete backfilling is common. Similarly, Luoyang shovels, during use and training, can also result in incomplete extraction and backfilling, again easily misleading police dogs due to the strong smell of fresh soil, leading to insufficient training and impacting the crime-solving rate.

[0004] Therefore, an odor extraction burial device was designed to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides an odor extraction burial device.

[0023] Odor extraction burial device.

[0024] In this implementation plan, an odor extraction burial device is designed to address the problems of existing tools used by police dogs to search for buried corpses, which are time-consuming, labor-intensive, expensive, cause significant damage to the soil, and may mislead police dogs due to incomplete backfilling.

[0025] Furthermore:

[0026] like Figures 1 to 3 As shown:

[0027] Based on the above, the device includes a long handle 1, a hollow cylindrical cone extractor 2, a push rod 3, a push plate 4, and a grip 5. The grip 5 is fixedly connected to the top of the long handle 1, the hollow cylindrical cone extractor 2 is fixedly connected to the bottom of the long handle 1, the push rod 3 is located inside the long handle 1 and the hollow cylindrical cone extractor 2, and the push rod 3 is slidably connected to both the long handle 1 and the hollow cylindrical cone extractor 2. The lower end of the push rod 3 is fixedly connected to the push plate 4.

[0028] In this implementation scheme, the device mainly consists of a long handle 1, a hollow cylindrical cone extractor 2, a push rod 3, a push plate 4, and a grip 5. The grip 5 is fixedly connected to the top of the long handle 1 for the user to hold and operate. The hollow cylindrical cone extractor 2 is fixedly connected to the bottom of the long handle 1, serving as the component for directly inserting into and extracting soil. The push rod 3 is located inside the long handle 1 and the hollow cylindrical cone extractor 2, and can slide relative to them. Its lower end is fixedly connected to the push plate 4, which, driven by the push rod 3, pushes out the soil extracted from the hollow cylindrical cone extractor 2, achieving soil backfilling. This structure solves the problem of incomplete soil extraction and backfilling in existing technologies using manual digging tools, achieving efficient and precise soil extraction and backfilling through the cooperation of various components.

[0029] Furthermore:

[0030] In an optional embodiment, the surface of the handle 1 is fitted with a foot pedal 6.

[0031] In this embodiment, a foot pedal 6 is installed on the surface of the long handle 1. The foot pedal 6 provides a point of force for the user, allowing the user to more easily drive the hollow cylindrical cone extractor 2 into the soil by stepping on the foot pedal 6. This reduces the difficulty of operation, improves the convenience and efficiency of soil extraction, and avoids the time-consuming and laborious drawback of inserting the tool by relying solely on hand strength in the prior art.

[0032] Furthermore:

[0033] In an optional embodiment, the outer surface of the grip 5 is provided with anti-slip texture.

[0034] In this embodiment, the outer surface of the handle 5 is provided with anti-slip texture.

[0038] Furthermore:

[0039] In an optional embodiment, a push handle 7 is fixedly connected to the upper end of the push rod 3, and a spring 8 is provided between the push handle 7 and the grip 5, with the spring 8 wrapped around the surface of the push rod 3.

[0040] In this implementation scheme: a push handle 7 is fixedly connected to the upper end of the push rod 3, and a spring 8 is provided between the push handle 7 and the grip 5, with the spring 8 wound around the surface of the push rod 3. The push handle 7 provides a more comfortable force application point for the user to push the push rod 3, while the spring 8, utilizing its elastic properties, can automatically reset the push rod 3 after the user releases the push handle 7, facilitating the next operation, improving the efficiency of soil backfilling, and making the device more convenient to use.

[0041] Working Principle: This device mainly consists of a long handle 1, a hollow cylindrical cone extractor 2, a push rod 3, a push plate 4, and a grip 5. The grip 5 is fixedly connected to the top of the long handle 1 for the user to hold and operate. The hollow cylindrical cone extractor 2 is fixedly connected to the bottom of the long handle 1, serving as the component that directly inserts into and extracts soil. The push rod 3 is located inside the long handle 1 and the hollow cylindrical cone extractor 2, and can slide relative to them. Its lower end is fixedly connected to the push plate 4, which, driven by the push rod 3, pushes out the soil extracted from the hollow cylindrical cone extractor 2, achieving soil backfilling. This structure solves the problem of incomplete soil extraction and backfilling in existing technologies using manual digging tools. Through the cooperation of various components, it achieves efficient and precise soil extraction and backfilling. A foot pedal 6 is installed on the surface of the long handle 1. The foot pedal 6 provides a leverage point for the user, allowing for easier and more effortless insertion of the hollow cylindrical cone extractor 2 into the soil. This reduces operational difficulty and improves the convenience and efficiency of soil extraction, avoiding the time-consuming and laborious drawbacks of relying solely on hand strength to insert the tool in existing technologies. The outer surface of the handle 5 is designed with anti-slip textures. These textures increase friction between the user's hand and the handle 5, preventing slippage due to sweaty hands or excessive force during operation. This ensures a stable grip on the device, enhancing operational safety and stability, and guaranteeing smooth extraction and backfilling processes. The hollow cylindrical cone extractor 2 is made of stainless steel with a smooth surface. Stainless steel is corrosion-resistant and has high strength, making it suitable for various soil environments. Its smooth surface reduces soil residue on the inner wall of the extractor, preventing odor residue from affecting the police dog's olfactory recognition. It also makes the extractor easier to insert into the soil and remove, improving the durability of the device and the accuracy of police dog training. The upper end of the push rod 3 is fixedly connected to the push handle 7. A spring 8 is provided between the push handle 7 and the grip 5, and the spring 8 is wrapped around the surface of the push rod 3.The push handle 7 provides a more comfortable point of force application for the user to push the push rod 3, while the spring 8, utilizing its elastic properties, can automatically reset the push rod 3 after the user releases the push handle 7, facilitating the next operation and improving the efficiency of soil backfilling. This makes the device more convenient to use. The user holds the handle 5 and checks whether the connections of each component of the device are secure, ensuring that the push rod 3 slides smoothly inside the long handle 1 and the hollow cylindrical cone extractor 2, and that the push plate 4 is firmly connected to the push rod 3. The user aligns the tip of the hollow cylindrical cone extractor 2 with the target soil position, and steps on the foot pedal 6 on the surface of the long handle 1 to apply downward force, causing the hollow cylindrical cone extractor 2 to gradually penetrate into the soil until it reaches the target soil position. Once the desired extraction depth is reached and insertion is complete, keep the handle 5 stable. The hollow cylindrical cone extractor 2 has already contained a certain amount of soil. At this point, lift the handle 5 upwards to remove the device along with the extracted soil from the soil. Hold the handle 5 and simultaneously push the push handle 7 at the top of the push rod 3, causing the push rod 3 to slide downwards inside the long handle 1 and the hollow cylindrical cone extractor 2. This will cause the push plate 4 to push the soil out of the hollow cylindrical cone extractor 2 and back into the original soil pit. Release the push handle 7. The spring 8 wrapped around the surface of the push rod 3 between the push handle 7 and the handle 5 will use its elasticity to push the push rod 3 upwards to reset, and the push plate 4 will also return to its initial position, completing one usage cycle.
