Description

Technical Field

[0001] The present invention relates to the field of sampling devices, and particularly to a fecal sampling device for random inspection and a detection method for the intestinal health of broilers. Background Art

[0002] Fecal detection, as a core means to evaluate the intestinal health of broilers, can non-invasively reflect the intestinal function status, pathogen infection risk and flora balance by analyzing the physical characteristics, microbial composition and biochemical indexes of feces, providing a key basis for disease early warning and management decision-making in farms. Normal feces are brown and have a uniform texture, while abnormalities such as loose stools, watery stools or bloody stools may indicate enteritis, coccidiosis infection or necrotic enteritis, and undigested feed particles suggest a decline in digestive and absorptive function or improper feed formulation.

[0003] Chinese Patent CN107817123B discloses a new fecal collection processor, which includes a fecal collection tube, a fecal sampler, a sample storage tube, a filter and a sample storage tube sealing cover. The lower end of the fecal sampler is provided with a sampling brush and a sampling tube to achieve multi-point collection of solid or liquid fecal samples; the fecal sampler and the fecal collection tube are hermetically combined to achieve dilution and mixing, sealed storage and transportation of the sample; the fecal collection tube, the filter and the sample storage tube are hermetically combined to achieve rough filtration of the sample; the sample storage tube and the sample storage tube sealing cover are hermetically combined to achieve sealed storage and transportation of the sample, enabling a series of operations such as multi-point collection, dilution and storage, and rough filtration of the fecal sample to be compactly connected and carried out in a sealed and centralized manner, standardizing the sample collection process, being convenient to operate, improving work efficiency, and at the same time, the collected sample is quantitatively accurate, safe and pollution-free, and is easy to store and transport.

[0004] Chinese Patent CN107091756B discloses a fecal sampling head and a sampling system, which includes a main body. The main body has a spiked part and a brush part. One end of the spiked part is a pointed structure, and the other end of the spiked part is connected to one end of the brush part; the circumferential direction of the brush part has bristles, and a storage area is formed between the bristles and the other end of the spiked part as a place to store the collected sample; it also includes a sampling rod connected to the other end of the brush part, significantly improving the user experience. By converting the multiple reciprocating operations during sampling into an automated rotational movement, the sampling efficiency is improved. At the same time, the adaptability of the sampling head to different fecal morphologies is improved, and the sampling quality is enhanced to ensure the accuracy of the test results.

[0005] The existing technology for random inspection and sampling of broiler feces mainly relies on traditional manual operations or simple tools. For example, the manual shoveling method uses a shovel or spoon to directly dig feces from the ground, which is easily mixed with impurities such as litter and feed residues, and there is a risk of the operator being exposed to pathogenic microorganisms; the disposable sampling rod is inserted into the feces through a spiral head and rotated for collection, but the collection volume of hard feces is insufficient, the adhesion of loose feces is poor, and the sampling rod is easily contaminated when exposed to the environment; the fixed collector uses a hard cup mouth to press and scrape the sample, but due to the fixed opening height, it is difficult to adapt to the infiltration of loose feces or the bulge of hard feces, resulting in unstable sample volume and easy leakage during transfer.

[0006] When collecting feces, the feces needs to be stored and transferred, and tools need to be used to collect the feces into a collection tank. The operation steps are cumbersome and the collection efficiency is low. In addition, the feces in the collection tank needs to be taken out when preparing samples, which further increases the operation steps. There are generally high health and safety risks, samples are contaminated by ground impurities, collection depth is uncontrollable, operation efficiency is low, and environmental adaptability is poor.

[0007] Therefore, the present application provides a feces sampling device and a method for detecting the intestinal health of broiler chickens to meet the needs. Summary of the invention

[0008] The purpose of the present application is to provide a feces sampling device and a method for detecting the intestinal health of broilers, which realizes the rapid and hygienic collection and closed transfer of feces samples. The feces sample is automatically cut and sealed by pressing the movable shell to drive the sealing plate, so that one-handed operation and contactless collection can be realized to avoid hand contamination. After the bottom of the collection shell is closed, the position of the movable shell is locked with the help of a one-way ratchet to form a sealed space to prevent sample leakage or external contamination. The elastic part stores energy and is linked with the one-way ratchet to keep the movable shell in a stable closed state after being pressed, and the transportation is safe and reliable. When sampling, only the push-out rod needs to be pressed to trigger the one-way ratchet to unlock, and the elastic part automatically resets the movable shell and links the push-out piston to push out the sample. The operation is smooth and there is no need to directly contact the sample throughout the process, which significantly reduces the risk of cross-contamination, and realizes the full-process closed-loop operation of pressing to collect → automatic closure → locking to prevent leakage → elastic reset → pushing the sample, which solves the problems of cumbersome operation, easy contamination, and easy deterioration of samples of traditional sampling tools.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Embodiment 1: Refer to Figures 1 - 11 A fecal sampling device for spot-checking as shown, which includes a collection shell 1. The bottom of the collection shell 1 is open. A closing assembly 2 is arranged on the collection shell 1. The closing assembly 2 includes an elastic member 21, a movable shell 22 and two closing plates 23. The movable shell 22 is sleeved on the collection shell 1. When the movable shell 22 moves downward, it can compress the elastic member 21 to store energy. The two closing plates 23 are arranged at the bottom of the collection shell 1. When the movable shell 22 moves downward, it can push the two closing plates 23 to move closer to each other and abut against each other to close the bottom opening of the collection shell 1.

The pushing piston 33 is slidably fitted in the collection shell 1, and the pushing rod 32 is fixedly installed on the pushing piston 33.

[0045] Hold the movable shell 22, align the bottom of the collection shell 1 with the feces, the bottom of the collection shell 1 is in contact with the ground, press the movable shell 22 downward. The movable shell 22 moves downward to drive the two closing plates 23 to move closer to each other. The two closing plates 23 cut the feces and close the bottom of the collection shell 1, collecting the feces into the collection shell 1. While the movable shell 22 moves downward, it compresses the elastic member 21 and drives the one-way ratchet 31 to rotate. The movable shell 22 cannot be reset upward under the restriction of the one-way ratchet 31. When it is necessary to take out the feces, press the pushing rod 32. The pushing rod 32 drives the pushing piston 33 to move in the collection shell 1. At the same time, the pushing rod 32 drives the one-way ratchet 31 to move. The one-way ratchet 31 loses the limit on the movable shell 22. The elastic member 21 pushes the movable shell 22 to reset, so that the two closing plates 23 move away from each other to open the collection shell 1. The pushing piston 33 pushes the feces from the opening end of the collection shell 1 into the beaker to complete the sampling.

[0046] It realizes the rapid and hygienic collection and enclosed transfer of fecal samples. By pressing the movable shell 22, the closing plate 23 is driven to automatically cut and seal the fecal sample, realizing one-handed operation and non-contact collection, avoiding hand contamination. After the bottom of the collection shell 1 is closed, the position of the movable shell 22 is locked by means of a one-way ratchet 31 to form a sealed space, preventing sample leakage or external contamination. The elastic member 21 stores energy and is linked with the one-way ratchet 31 to keep the movable shell 22 in a stable closed state after pressing. The transportation is safe and reliable. And when sampling, only by pressing the push rod 32 can the one-way ratchet 31 be triggered to unlock, and the elastic member 21 automatically resets the movable shell 22 and drives the push piston 33 to push out the sample. The operation is smooth and the sample is not directly contacted throughout the process, significantly reducing the risk of cross-contamination, realizing the full-process closed-loop operation of pressing collection → automatic closing → locking to prevent leakage → elastic reset → pushing out the sample, and solving the problems of cumbersome operation, easy contamination, and easy deterioration of samples of traditional sampling tools.

When the locking gear 35 rotates, it can drive the rotating gear 37 to rotate through the locking belt member 36. The rotating tooth ring 38 is fixedly installed on the one-way ratchet 31. The rotating gear 37 meshes with the rotating tooth ring 38, and the rotating gear 37 is located above the rotating tooth ring 38.

[0049] When the movable shell 22 moves downward, the movable shell 22 drives the locking rack 34 to move downward. The locking rack 34 drives the locking gear 35 to rotate. The locking gear 35 drives the rotating gear 37 to rotate through the locking belt member 36. The rotating gear 37 drives the rotating tooth ring 38 to rotate. The rotating tooth ring 38 drives the one-way ratchet 31 to rotate. Due to the one-way rotation characteristic of the one-way ratchet 31, the movable shell 22 is limited and cannot be reset upward, keeping the closing plate 23 in a closed state.
