Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a fecal sampling device for poultry farming cages. Background Technology

[0002] Fecal sampling is a routine and important task in poultry health monitoring and disease diagnosis.

[0003] Currently, common sampling methods often involve handheld samplers or simple tools to directly scrape the sample. These methods have the following problems: First, the operator's hands need to be very close to or even in direct contact with feces, resulting in poor hygiene and a risk of disease transmission. Second, for cages located at high or deep levels, operation is extremely inconvenient and it is difficult to apply a stable suction force. Third, existing samplers are prone to shaking during sampling, leading to inaccurate sampling amounts or sample spillage, which affects the accuracy of test results. To address the shortcomings of existing technology, this invention provides a fecal sampling device for poultry farming cages to solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment discloses a feces sampling device for poultry farming cages, according to the attached... Figure 1 To be continued Figure 5As shown, it includes a sampling frame 1, a sampling cylinder 2, a limiting plate 3, an upper cover 4, and a driving mechanism.

[0021] According to the appendix Figure 1 Appendix Figure 3 and attached Figure 4 As shown, the sampling frame 1 serves as the main support structure of the device. One end of the frame is provided with a base 11 for supporting the sample collection tube 2, and the other end is provided with a first handle 12 for easy gripping and operation by the user.

[0022] According to the appendix Figure 1 Appendix Figure 4 and attached Figure 5 As shown, the sampling cylinder 2 is the sampling component of this device. Its front end is equipped with a suction tube 21 for absorbing feces, and the front end of the suction tube 21 has an arc-shaped portion 22 for easy insertion into the feces pile. Inside the sampling cylinder 2, a piston 23 is installed, and a rearwardly extending push rod 24 is fixedly connected to the piston 23. The end of the push rod 24 extends out of the cylinder body of the sampling cylinder 2. A limiting plate 3 is fixedly installed on the side wall of the sampling cylinder 2. Furthermore, the base 11 has a recess that matches the shape of the bottom of the sampling cylinder 2, used for initial locking and limiting of the installed sampling cylinder 2.

[0023] According to the appendix Figure 1 and attached Figure 4 As shown, the upper cover 4 is used to press and fix the sampling cylinder 2 from above. A retaining plate 41 extends downwards from the side of the upper cover 4. When the upper cover 4 is closed onto the base 11, its retaining plate 41 engages precisely with the limiting plate 3 on the sampling cylinder 2. Furthermore, the upper cover 4 and the base 11 are detachably fixed together by a fixing bolt 42. When the fixing bolt 42 is tightened, the upper cover 4, the sampling cylinder 2, and the base 11 are secured as a single unit, and the engagement of the limiting plate 3 and the retaining plate 41 effectively prevents the sampling cylinder 2 from rotating circumferentially, ensuring its stability during operation.

[0024] According to the appendix Figure 1 Appendix Figure 2 and attached Figure 5 As shown, the drive mechanism is used to remotely control the movement of piston 23 to generate negative pressure. This mechanism includes a sliding seat 5, a steel wire 51, and a second grip 52. The sliding seat 5 is slidably connected to the sampling frame 1 and has a locking slot for engaging with the protrusion at the end of the push rod 24, thereby achieving power transmission. One end of the steel wire 51 is fixedly connected to the sliding seat 5, and the other end passes through a dedicated channel on the sampling frame 1 and is fixedly connected to the second grip 52. It is particularly important to note that the second grip 52 is positioned close to the first grip 12, allowing the user to easily operate the second grip 52 while holding the first grip 12 with one hand, or by pulling it with the other hand or other fingers of the same hand.

[0025] The sampling frame 1 is threaded with a locking bolt 121 for locking and limiting the steel wire 51. Therefore, when the drive mechanism is not needed, the steel wire 51 can be locked and limited by the locking bolt 121 to ensure the stability of the device.

[0026] According to the appendix Figure 1 To be continued Figure 5 As shown, the working principle of this device is as follows: First, place the sampling cylinder 2 into the recess of the base 11, aligning its limiting plate 3. Then, cover the top cover 4, ensuring that the locking plate 41 of the top cover 4 engages with the limiting plate 3, and tighten the fixing bolt 42 to secure the top cover 4. At this point, insert the protrusion at the end of the push rod 24 into the slot of the sliding seat 5 to complete the assembly of the device.

[0027] During sampling, the user holds the first handle 12 with one hand and aligns the suction tube 21 at the front end of the sampling cylinder 2 with the feces to be sampled. Then, the user pulls the second handle 52 backward with their finger. The second handle 52 pulls the sliding seat 5 backward on the sampling frame 1 via the steel wire 51. The sliding seat 5 then drives the push rod 24 and piston 23 to move backward, thereby generating negative pressure in the sealed inner cavity of the sampling cylinder 2. Under this negative pressure, the fecal sample is sucked into the inner cavity of the sampling cylinder 2 through the suction tube 21, completing one sampling. After releasing the second handle 52, the piston mechanism can be manually pushed back to its original position.

[0028] Example 1: This example uses sampling of poultry manure from the upper layer of a multi-layer cage as an example, combined with the attached... Figure 1 To be continued Figure 5 Detailed workflow description: The workflow is as follows: The user stands in front of the cage, which is quite high, and needs to raise the device to a suitable height. The user firmly grips the first handle 12 on the sampling frame 1 with one hand and precisely inserts the curved part 22 of the suction tube 21 into the target feces. The other hand easily pulls the second handle 52 from below, allowing the user to remotely complete the sampling process. Throughout the entire process, the user does not need to bring their hand close to the feces or make any large movements, making it safe, effortless, and hygienic.

[0029] Example 2: This example takes disassembly and cleaning after sampling as an example, combined with the attached... Figure 1 and attached Figure 4 Detailed workflow description: The workflow is as follows: After sampling, loosen and remove the fixing bolt 42, and open the top cover 4. At this point, the sampling cylinder 2 can be directly removed upwards, and the limiting plate 3 and the clamping plate 41 will automatically separate. Send the removed sampling cylinder 2 to the laboratory for testing and analysis. Afterwards, the sampling cylinder 2 can be thoroughly cleaned and disinfected, or the push rod 24 can be pulled out to perform a separate deep cleaning of the piston 23. The top cover 4, sampling rack 1, and other components can also be easily wiped clean. The modular design greatly facilitates the maintenance of the device.

[0030] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
