Description

Technical Field

[0001] The invention relates to the field of sampling devices, and in particular to a feces sampling device and a method for detecting the intestinal health of broiler chickens. Background Art

[0002] Fecal testing is the core means of evaluating the intestinal health of broilers. By analyzing the physical characteristics, microbial composition and biochemical indicators of feces, it can non-invasively reflect the intestinal function status, pathogen infection risk and flora balance, providing a key basis for disease warning and management decisions in farms. Normal feces are brown and uniform in texture, while abnormalities such as loose stools, watery stools or bloody stools may indicate enteritis, coccidia infection or necrotic enteritis, and undigested feed particles indicate decreased digestion and absorption function or improper feed formulation.

[0003] Chinese patent CN107817123B discloses a novel stool collection processor, including a stool collection tube, a stool collector, a sample storage tube, a filter and a sample storage tube sealing cover. The lower end of the stool collector is provided with a sampling brush and a sampling tube to realize multi-point collection of solid or liquid stool samples; the stool collector and the stool collection tube are sealed to realize dilution, mixing, sealed storage and transportation of the sample; the stool collection tube, the filter and the sample storage tube are sealed to realize coarse filtration of the sample; the sample storage tube and the sample storage tube sealing cover are sealed to realize sealed storage and transportation of the sample, so that a series of work such as multi-point collection, dilution storage and coarse filtration of stool samples are closely connected and carried out in a closed and centralized manner, so that the sample collection process is standardized, the operation is convenient, and the work efficiency is improved. At the same time, the collected samples are quantitatively accurate, safe and pollution-free, and easy to store and transport; Chinese patent CN107091756B discloses a stool sampling head and a sampling system, including a main body, wherein the main body has a spike portion and a brush portion, wherein one end of the spike portion is a pointed structure, and the other end of the spike portion is connected to one end of the brush portion; the brush portion has bristles in the circumference, and a storage area is formed between the bristles and the other end of the spike portion, which serves as a place for storing collected samples; and also includes a sampling rod, which is connected to the other end of the brush portion, thereby significantly improving the user experience, and improving the sampling efficiency by converting multiple reciprocating operations during sampling into automated rotational motions. At the same time, the adaptability of the sampling head to different stool forms is improved, and the accuracy of the test results is guaranteed by improving the sampling quality.

[0004] 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.

[0005] 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.

[0006] 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

[0007] 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.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1: Reference Figure 1-Figure 11A feces sampling device shown in the figure comprises a collection shell 1, the bottom of the collection shell 1 is open, a closing assembly 2 is arranged on the collection shell 1, and the closing assembly 2 comprises 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 force, and 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 approach each other and abut against each other, so as to close the bottom opening of the collection shell 1; A locking and ejecting assembly 3 is provided on the collection shell 1, and the locking and ejecting assembly 3 includes a one-way ratchet 31, an ejecting rod 32 and an ejecting piston 33.

When the movable shell 22 moves downward, it can drive the one-way ratchet 31 to rotate, and the ejecting piston 33 is slidably fitted in the collection shell 1, and the ejecting rod 32 is fixedly installed on the ejecting piston 33.

[0024] The movable shell 22 is held in place and the bottom of the collecting shell 1 is aligned with the feces. The bottom of the collecting shell 1 contacts the ground, and the movable shell 22 is pressed downward. The movable shell 22 moves downward and drives 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 collecting shell 1 to collect the feces into the collecting shell 1. The movable shell 22 compresses the elastic member 21 while moving downward, 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 the feces needs to be taken out, the ejection rod 32 is pressed, and the ejection rod 32 drives the ejection piston 33 to move in the collecting shell 1. At the same time, the ejection 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, the collecting shell 1 is opened, and the ejection piston 33 pushes the feces from the open end of the collecting shell 1 into the beaker to complete the sampling.

[0025] The rapid and sanitary collection and closed transfer of fecal samples are realized. The closing plate 23 is driven by pressing the movable shell 22 to automatically cut and seal the fecal sample, so that one-handed operation and contactless collection are realized to avoid hand contamination. After the bottom of the collection shell 1 is closed, the position of the movable shell 22 is locked with the help of the one-way ratchet 31 to form a sealed space to prevent 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 being pressed, so that transportation is safe and reliable. When sampling, only the push rod 32 needs to be pressed to trigger the unlocking of the one-way ratchet 31. The elastic member 21 automatically resets the movable shell 22 and links the push piston 33 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. The full-process closed-loop operation of pressing to collect → automatic sealing → locking to prevent leakage → elastic reset → pushing for sample discharge is realized, which solves the problems of cumbersome operation, easy contamination, and easy deterioration of samples of traditional sampling tools.

The locking rack 34 is fixedly mounted on the inner wall of the movable shell 22, and the locking gear 35 is meshed with the locking rack 34. When the locking gear 35 rotates, it can drive the rotating gear 37 to rotate through the locking belt member 36. The rotating ring gear 38 is fixedly mounted on the one-way ratchet 31, and the rotating gear 37 is meshed with the rotating ring gear 38. The rotating gear 37 is located above the rotating ring gear 38.

[0028] 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 36, the rotating gear 37 drives the rotating ring gear 38 to rotate, and the rotating ring gear 38 drives the one-way ratchet 31 to rotate. Due to the unidirectional rotation characteristic of the one-way ratchet 31, the limited movable shell 22 cannot be reset upward, so that the closing plate 23 remains in a closed state.

[0029] Example 3, reference Figure 1-Figure 11 , which is different from the above-mentioned embodiment, the closing component 2 also includes two closing units, which include a connecting rack 24, a connecting gear 25, a connecting belt member 26, a closing gear 27 and a closing rack 28. The connecting rack 24 is installed on the outer wall of the movable shell 22, and the connecting gear 25 is meshed with the connecting rack 24. When the connecting gear 25 rotates, the closing gear 27 can be driven to rotate through the connecting belt member 26. The closing rack 28 is meshed with the closing gear 27, and the closing rack 28 is installed on the corresponding closing plate 23.

[0032] Press the movable shell 22 downward, the lifting plate 41 contacts the ground, so that the closing plate 23 has a certain distance from the ground. The closing plate 23 has a certain height when cutting feces, and will not collect feces in contact with the ground, preventing the part of the feces in contact with the ground from being contaminated. When facing different ground surfaces and feces in different states and needing to adjust the height of the closing plate 23 and the ground, turn the lifting knob, the lifting knob drives the lifting screw 42 to rotate, and the lifting screw 42 drives the lifting plate 41 to move, thereby adjusting the distance between the lifting plate 41 and the closing plate 23.

[0033] By pressing the movable shell 22 downward, the lifting plate 41 is in contact with the ground, so that the closing plate 23 maintains a preset distance from the ground, avoiding the closing plate 23 from directly cutting the contaminated part of the feces in contact with the ground, thereby ensuring the cleanliness of the collected samples; when it is necessary to adapt to different ground surfaces such as uneven surfaces or different forms of feces such as inconsistent thickness, the lifting knob is turned to drive the lifting screw 42 to rotate, and the distance between the lifting plate 41 and the closing plate 23 is adjusted, so as to flexibly control the effective height of the closing plate 23 cutting the feces, thereby avoiding contamination or incomplete collection caused by mixing of ground impurities or improper sample cutting depth.

After the blocking rod 314 rotates and contacts with the internal gear 313, the blocking spring piece 315 is deformed, so that the blocking rod 314 itself rotates and the teeth of the internal gear 313 are staggered. Since the blocking rod 314 is inclined, when the bottom plate 312 and the outer ring 311 rotate in the opposite direction, the blocking rod 314 and the internal gear 313 are stuck, achieving the effect of one-way rotation.
