Description

Technical Field

[0001] This utility model relates to the field of feed production technology, and in particular to a sample extraction device for detecting microorganisms in feed. Background Technology

[0002] Feed is a general term for the food consumed by all domesticated animals. In a narrower sense, feed mainly refers to the food consumed by animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed ingredients, such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. Feed contains a variety of microorganisms. Contamination of feed products by certain microorganisms not only affects the quality of the feed itself, but more seriously, it endangers the health and safety of consumers. Therefore, during the feed production process, samples are taken and tested to ensure feed safety.

[0003] A sample extraction device for detecting microorganisms in feed, disclosed in Chinese patent CN216594241U, has a simple and reasonable structural design and is easy to operate. It can conveniently collect feed samples from different depths, reducing detection errors. However, while solving the problem, this sample extraction device for detecting microorganisms in feed has the following drawbacks:

[0004] 1. The sample extraction tube is equipped with a movable plate that blocks the inside of the sample extraction tube. When the sample extraction tube is inserted into the feed, the front of the movable plate will be against the feed, which will create a large resistance and make it inconvenient to use.

[0005] 2. Both the first and second pull ropes need to have a certain degree of flexibility to be used normally. However, ropes with better flexibility have poorer wear resistance. When this device is in use, the pull ropes will rub against the threading groove and feed, and will eventually wear out and break. The structure is unreasonable and the service life is short. Utility Model Content

[0006] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0007] Therefore, one objective of this invention is to provide a sample extraction device for detecting microorganisms in feed, in order to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0008] To achieve the above objectives, one embodiment of the present invention provides a sample extraction device for detecting microorganisms in feed, comprising a sleeve and a sampling tube, wherein the sampling tube is rotatably connected inside the sleeve, a feed trough is provided at one end of the sleeve, a sampling trough is provided at the position of the sampling tube corresponding to the feed trough, and a pointed end is fixedly connected to one end of the sleeve near the feed trough.

[0009] Preferably, of any of the above embodiments, a handle is fixedly connected to the end of the sampling tube away from the sampling groove, and a scale is provided on the outer surface of the sleeve. The handle facilitates the rotation of the sampling tube, and the scale facilitates the determination of the depth to which the device is inserted into the feed.

[0010] Preferably, of any of the above solutions, an indicator strip is provided at the end of the sleeve away from the tip, and a pointer and a reference strip are fixedly connected at the end of the sampling tube away from the tip. When the device is inserted into the feed, it is convenient to determine whether the feed trough and the sampling trough correspond.

[0011] Preferably, the sampling tube has an exhaust port at the end away from the tip, which can improve the sampling efficiency.

[0012] Another embodiment of this utility model provides a sample extraction device for detecting microorganisms in feed, including a sleeve and a sampling tube. The sampling tube is rotatably connected inside the sleeve. A feed groove is opened at one end of the sleeve. A sampling groove is opened at the position of the sampling tube corresponding to the feed groove. A pointed tip is fixedly connected to the end of the sleeve near the feed groove. A positioning sleeve is fixedly connected to the outer surface of the end of the sleeve away from the pointed tip. A pull rod is slidably connected inside the positioning sleeve. A reset plate is fixedly connected to one end of the pull rod. A spring is provided between the positioning sleeve and the reset plate. A positioning block is fixedly connected to the end of the pull rod away from the reset plate. A positioning groove is opened at the edge of the end of the sampling tube away from the pointed tip.

[0013] Preferably, of any of the above schemes, there are two positioning grooves, and the two positioning grooves are symmetrically arranged at the edge of one end of the sampling tube. The positioning grooves are used to fix the sampling tube when the feed trough is closed or open.

[0014] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0015] 1. The head of the device is pointed, and the feed trough is set on the surface of the device, so that there is little resistance when inserting it into the feed for sampling, making it easy to insert and thus more convenient to use.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example 1:

[0026] like Figure 1-2 As shown, a sample extraction device for detecting microorganisms in feed according to this embodiment includes: a sleeve 1, wherein the sleeve 1 has a feed trough 3 for material entry and exit;

[0027] The sampling tube 2 is installed inside the sleeve 1 and can be rotatably connected to the sleeve 1. The sampling tube 2 has a sampling groove 4 for receiving the sample. The sampling groove 4 is correspondingly arranged with the feed groove 3 to realize the sampling of materials. When the sampling tube 2 is rotated, the feed can enter the sampling tube 2 when the sampling groove 4 is aligned with the feed groove 3. When the sampling tube 2 is rotated, the feed cannot enter the sampling tube 2 when the sampling groove 4 is facing away from the feed groove 3. A pointed tip 5 is fixedly connected to one end of the sleeve 1 near the feed groove 3 for inserting the device into the feed.

[0028] Indicator bar 8 is disposed at one end of the sleeve 1 to indicate the initial sampling position;

[0029] Pointer 9 is located on one side of the sampling tube 2 and cooperates with the indicator strip 8 to indicate the position at the start of sampling;

[0030] A reference bar 10 is disposed on one side of the sampling tube 2 and cooperates with the pointer 9 to indicate the position when sampling is completed. During the sampling process, when the pointer 9 is aligned with the indicator bar 8, the feed chute 3 and the sampling chute 4 are in corresponding positions to allow material to enter. When sampling is completed, when the reference bar 10 is aligned with the pointer 9, the feed chute 3 and the sampling chute 4 are in a misaligned state to prevent material from continuing to enter or leaking.

[0031] A handle 6 is fixedly connected to the end of the sampling tube 2 away from the sampling groove 4. The sampling tube 2 can be rotated by the handle 6 to adjust the direction of the sampling groove 4. A scale 7 is provided on the outer surface of the sleeve 1. When the sleeve 1 is inserted into the feed, the insertion depth can be observed by the scale 7 to determine the sampling depth.

[0032] The sampling tube 2 has an exhaust hole 11 at the end away from the tip 5. When the feed enters the sampling tube 2, the air in the sampling tube 2 is discharged through the exhaust hole 11, thereby accelerating the speed at which the feed enters the sampling tube 2 and improving the sampling efficiency.

[0033] The working principle of the sample extraction device for feed microbial detection in this embodiment is as follows:

[0034] Rotate the sampling tube 2 so that the sampling groove 4 faces away from the feed trough 3. Then insert the device into the feed through the pointed end 5. After inserting to a certain depth, rotate the sampling tube 2 so that the sampling groove 4 is aligned with the feed trough 3, so that the feed will enter the sampling tube 2. Then rotate the sampling tube 2 again so that the sampling groove 4 faces away from the feed trough 3 again. Pull the device out of the feed to complete the sampling. Example 2:

[0035] As shown in Figure 3, the sample extraction device for feed microbial detection in this embodiment differs from that in Embodiment 1 in that a positioning sleeve 12 is fixedly connected to the outer surface of the end of the sleeve 1 away from the tip 5. A pull rod 13 is slidably connected inside the positioning sleeve 12. A reset plate 14 is fixedly connected to one end of the pull rod 13. A spring 15 is provided between the positioning sleeve 12 and the reset plate 14. The spring 15 is sleeved on the surface of the pull rod 13. The elastic force of the spring 15 can push the reset plate 14 to move the pull rod 13. A positioning block 16 is fixedly connected to the end of the pull rod 13 away from the reset plate 14. A positioning groove 17 is provided at the edge of the sampling tube 2 away from the tip 5. When the positioning block 16 is inserted into the positioning groove 17, it can fix the sampling tube 2, preventing the sampling tube 2 from rotating inside the sleeve 1. There are two positioning grooves 17, and the two positioning grooves 17 are symmetrically arranged at the edge of one end of the sampling tube 2. This corresponds to the opening and closing states of the feed trough 3.

[0036] The working principle of the sample extraction device for feed microbial detection in this embodiment is as follows:

[0037] When sampling, rotate the sampling tube 2 so that the sampling slot 4 faces away from the feed slot 3. The spring 15 pushes the reset plate 14, causing the pull rod 13 to pull the positioning block 15 into the positioning slot 17 to fix the sampling tube 2. This avoids the problem of the sampling tube 2 rotating and opening the feed slot 3 during the insertion of the device into the feed. After insertion to the specified depth, press the reset plate 14 to disengage the positioning block 16 from the positioning slot 17. Then rotate the sampling tube 2 to open the feed slot 3. Then release the reset plate 14 to allow the positioning block 16 to be inserted into another positioning slot 17.

[0038] Compared with the prior art, the present invention has the following advantages:

[0039] 1. The head of the device is a pointed tip 5, and the feed trough 3 is set on the surface of the device, so that when it is inserted into the feed for sampling, the resistance is small and the insertion is convenient, making it more convenient to use.

[0040] 2. The feed trough 3 and the sampling trough 4 are respectively set on the surface of the sleeve 1 and the sampling tube 2. The feed trough 3 can be opened and closed by rotating the sampling tube 2. The structure is simple and reasonable, not easy to be damaged, and has a long service life.

[0041] 3. In Example 2, the positioning block 16 and positioning groove 17 are designed so that during the sampling process, the positioning block 16 and positioning groove 17 can fix the sampling tube 2 by cooperating during the insertion into the feed. This eliminates the need to worry about whether the feed trough 3 is open during the insertion process, which may affect the sampling results and improves practicality.
