Description

Technical Field

[0001] The present invention relates to the technical field of microbial feed detection sampling, and specifically to a sampling device for microbial feed detection. Background Art

[0002] During the production, storage, and use of microbial feed, detecting its quality and composition is an important link to ensure the safety and effectiveness of the feed. To perform accurate detection, a representative sample needs to be obtained from the storage tank. Especially when dealing with microbial feed stored for a long time, the traditional sampling method is usually to manually use simple tools to obtain feed samples from the storage tank, and this method has many problems.

[0003] For example, during the long-term storage of microbial feed, due to the influence of moisture, microbial activity, and environmental factors, caking is likely to occur; this caking will cause changes in the physical properties of the feed, making it difficult for traditional sampling devices to effectively collect representative samples. For example, the caked feed may not move to the sampling area by itself, resulting in a reduced sampling effect; the lack of a function to disturb the feed, so that when sampling, the caked feed cannot be effectively gathered into the sampling area, resulting in an extended sampling time and low efficiency.

[0004] During the sampling process, existing devices often cannot effectively block the sampling port. When the sampling mechanism is withdrawn, the microbial feed may fall off by itself, or be interfered by the feed in other positions, resulting in sample contamination and affecting the accuracy of the detection results. Summary of the Invention

[0005] (I) Technical Problems to be Solved Aiming at the deficiencies of the prior art, the present invention provides a sampling device for microbial feed detection. By fixing the cover plates in the sampling mechanism to the two rotating shafts respectively, when the two rotating shafts are driven to rotate by the driving member, the two cover plates can be driven to perform a flipping motion. Through the flipping of the two cover plates, not only the microbial feed around the feed inlet is gathered towards the position of the feed inlet, improving the collection effect, but also the feed inlet after sampling can be blocked, preventing the microbial feed from falling off by itself or being interfered by the microbial feed in other positions when the sampling mechanism is withdrawn, solving the problem that the sampling device in the prior art lacks the function of disturbing the feed during sampling, resulting in the caked microbial feed due to long-term storage being unable to move to the sampling area by itself, thereby reducing the sampling effect.

[0006] (II) Technical Solutions To achieve the above object, the present invention provides the following technical solution: A sampling device for detecting microbial feed, comprising a storage tank for storing microbial feed and a sampling mechanism for sampling the microbial feed stored inside the storage tank, and a ladder is installed on the storage tank; A plurality of sampling frames are fixedly installed on the storage tank, and a sealing component for sealing and plugging the sampling frame is arranged on the sampling frame; The sampling mechanism includes a control frame for inserting into the storage tank through the sampling frame. One side of the control frame is fixedly connected with an extraction frame, and feed inlets are formed on both sides of the extraction frame.

[0007] Preferably, the sealing component includes a movable frame fixedly communicated with one end of the sampling frame. Two sealing baffles for plugging the inside of the sampling frame are slidably connected inside the movable frame; Spring groups are fixedly connected between the inside of the movable frame and the two sealing baffles. The spring groups are used for elastically squeezing the sealing baffles to make the two sealing baffles move in opposite directions.

[0008] Preferably, two cover plates for covering the feed inlets are arranged on the outer side surface of the extraction frame, and a control member for controlling the extension of the two cover plates is arranged between the inside of the control frame and the extraction frame. One end of the extraction frame is conical, and inclined inlets are formed at the opposite ends of the two sealing baffles.

[0009] Preferably, the control member includes two rotating shafts rotatably connected to the extraction frame and a driving member for rotating and driving the two rotating shafts. The two cover plates are respectively fixedly connected to the outer side surfaces of the two rotating shafts.

[0010] Preferably, the driving member includes connecting blocks fixed to the inner side surfaces of the two rotating shafts. A connecting rod is fixedly connected to the two connecting blocks. A sliding frame is slidably connected inside the control frame. One ends of the two connecting rods both extend into the inside of the control frame, and one ends of the two connecting rods are both fixedly connected to the sliding frame.

[0011] Preferably, touch blocks are fixedly connected to both sides of the sliding frame, and both touch blocks extend outside the control frame.

[0012] Preferably, guide posts are fixedly connected to the outer surfaces of the two connecting rods. Elastic friction sleeves are slidably sleeved on the outer surfaces of the two guide posts. The two elastic friction sleeves are both fixedly connected to the inside of the control frame through support rods.

[0013] Preferably, collection components are arranged on both sides inside the movable frame. The collection components include collection plates for collecting the microbial feed inside the storage tank to the position of the extraction frame.

[0014] (III) Beneficial effects Compared with the prior art, the present invention provides a sampling device for detecting microbial feed, having the following beneficial effects: 1. In the present invention, the cover plates in the sampling mechanism are respectively fixedly connected to the two rotating shafts. Thus, when the two rotating shafts are rotationally driven by the driving member, the two cover plates can be driven to perform a flipping motion. Through the flipping of the two cover plates, not only the microbial feed around the feed inlet is collected towards the position of the feed inlet, improving the collection effect, but also the sampled feed inlet can be blocked to prevent the microbial feed from falling off by itself when the sampling mechanism is withdrawn or the microbial feed at other positions from interfering with the collected feed. This solves the problem that in the prior art, during sampling, the sampling device lacks disturbance to the feed, resulting in caked microbial feed due to long-term storage, which cannot move to the sampling area by itself, thereby reducing the sampling effect.

[0015] 2. In the present invention, two sealing baffles are slidably connected inside the movable frame. Through the arrangement of the two sealing baffles, the communication position between the movable frame and the sampling frame can be sealed to prevent the leakage of microbial feed inside the storage tank. Moreover, when the control frame and the extraction frame in the sampling mechanism are inserted into the sampling frame, the two sealing baffles can not only be automatically unfolded to realize the automatic sampling work of the extraction frame, but also by gradually unfolding or folding the two sealing baffles, it is effectively ensured that when the control frame and the extraction frame are inserted or pulled out, the microbial feed inside the storage tank will not leak.

[0016] 3. In the present invention, the two toothed plate frames in the collection assembly are respectively connected to the two sealing baffles. When the two sealing baffles are pushed and driven to expand under the extrusion force of the extraction frame or the control frame, the two toothed plate frames can be synchronously driven to move away from each other, thereby driving the two gears to rotate symmetrically. Finally, the two collection plates can be driven to move in opposite directions through the rotating shaft and the connecting frame, so that the caked microbial feed inside the storage tank is driven towards the position of the extraction frame, facilitating the microbial feed to better enter the extraction frame through the feed inlet to form the microbial feed sampling work. This not only effectively prevents the caking phenomenon of the microbial feed inside the storage tank due to long-term storage, which affects the sampling effect, but also effectively utilizes the driving force during sampling to form the function of automatic collection and sampling.

Specific embodiments

[0019] 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.

[0020] Embodiment 1: Refer to the attached Figures 1 to 10, A sampling device for detecting microbial feed, including a storage tank 100 for storing microbial feed and a sampling mechanism 200 for sampling the microbial feed stored inside the storage tank 100, and a ladder 1 is installed on the storage tank 100; Through the setting of the ladder 1, it is convenient for the staff to use the sampling mechanism 200 to sample and collect the microbial feed at different heights inside the storage tank 100; A number of sampling frames 2 are fixedly installed on the storage tank 100, and a sealing component 3 for sealing and plugging the sampling frame 2 is arranged on the sampling frame 2; Through the setting of the sampling frame 2, it is convenient for the sampling mechanism 200 to insert into the inside of the storage tank 100 for sampling work. Through the setting of the sealing component 3, it is used to seal and plug the sampling frame 2, which not only ensures that there is no problem of leakage of microbial feed during sampling, but also ensures the storage effect of microbial feed; The sampling mechanism 200 includes a control frame 4 for inserting into the inside of the storage tank 100 through the sampling frame 2. One side of the control frame 4 is fixedly connected with a extraction frame 5, and feed inlets 6 are opened on both sides of the extraction frame 5. Two inclined guiding blocks are fixedly connected between the extraction frame 5 and the control frame 4, and a U-shaped handle is fixedly connected to the control frame 4; When the control frame 4 and the extraction frame 5 in the sampling mechanism 200 cooperate with the sampling frame 2 to insert into the inside of the storage tank 100, the microbial feed can be sampled through the feed inlets 6. When the extraction frame 5 is inserted into the sampling frame 2 for sampling, the sealing component 3 can realize automatic expansion or retraction movement, further improving the convenience of sampling and the effect of sealing treatment.

[0021] Refer to the appendix Figure 5 、 Figure 7 and Figure 8 , The sealing component 3 includes a movable frame 31 fixedly communicated with one end of the sampling frame 2, and two sealing baffles 32 for plugging the inside of the sampling frame 2 are slidably connected inside the movable frame 31; By slidably connecting two sealing baffles 32 inside the movable frame 31, through the setting of the two sealing baffles 32, the communication position between the movable frame 31 and the sampling frame 2 can be sealed to prevent the leakage of microbial feed inside the storage tank 100; Spring groups 33 are fixedly connected between the inside of the movable frame 31 and the two sealing baffles 32. The spring groups 33 are used to elastically extrude the sealing baffles 32 to make the two sealing baffles 32 move in the opposite direction; Through the setting of the two spring groups 33, the two sealing baffles 32 can be extruded, so that the two sealing baffles 32 move in the opposite direction, and then the sampling frame 2 is blocked to prevent the leakage of microbial feed inside the storage tank 100.

[0022] Referring to the attached Figure 9 and Figure 10 , two cover plates 7 for blocking the feed inlet 6 are arranged on the outer side surface of the extraction frame 5, and a control member 8 for controlling the extension of the two cover plates 7 is arranged between the control frame 4 and the inside of the extraction frame 5. One end of the extraction frame 5 is set in a conical shape, and inclined inlets 34 are formed at opposite ends of the two sealing baffles 32; Through the arrangement of the control member 8, the two cover plates 7 can be driven to extend. Through the arrangement of the cover plates 7, the feed inlet 6 can be blocked to prevent the microbial feed from falling off by itself when the sampling mechanism 200 is withdrawn, or the microbial feed at other positions from interfering with the collected feed; One end of the extraction frame 5 is set in a conical shape, and inclined inlets 34 are formed at opposite ends of the two sealing baffles 32. When the extraction frame 5 is inserted into the sampling frame 2 and abuts against the two sealing baffles 32, the conical port can be inserted into the two overlapping inclined inlets 34, so that the two sealing baffles 32 move away from each other, forming the expansion of the port position of the sampling frame 2, and then facilitating the control frame 4 and the extraction frame 5 to be inserted into the storage tank 100 for sampling work.

[0023] Referring to the attached Figure 9 and Figure 10 , the control member 8 includes two rotating shafts 81 rotatably connected to the extraction frame 5 and a driving member for driving the rotation of the two rotating shafts 81. The two cover plates 7 are respectively fixedly connected to the outer side surfaces of the two rotating shafts 81; By fixedly connecting the cover plates 7 to the two rotating shafts 81 respectively, when the driving member drives the two rotating shafts 81 to rotate, the two cover plates 7 can be driven to flip. Through the flipping of the two cover plates 7, not only the microbial feed around the feed inlet 6 is gathered towards the position of the feed inlet 6 to improve the collection effect, but also the sampled feed inlet 6 can be blocked to prevent the microbial feed from falling off by itself when the sampling mechanism 200 is withdrawn, or the microbial feed at other positions from interfering with the collected feed.

[0024] Embodiment 2: Different from Embodiment 1; Referring to the attached Figure 9 and Figure 10 , the driving member includes connection blocks 82 fixed to the inner side surfaces of the two rotating shafts 81. A connecting rod 83 is fixedly connected to the two connection blocks 82. A sliding frame 84 is slidably connected to the inside of the control frame 4. One end of each of the two connecting rods 83 extends into the control frame 4, and one end of each of the two connecting rods 83 is fixedly connected to the sliding frame 84; By controlling the sliding of the sliding frame 84, the telescopic movement of the two connecting rods 83 can be driven. Furthermore, the rotating shaft 81 can be driven to rotate through the two connecting blocks 82. Through the rotation of the two rotating shafts 81, the two cover plates 7 can be driven to flip synchronously, thereby blocking the two feeding ports 6, preventing the microbial feed from falling off by itself or being interfered by the microbial feed in other positions when the sampling mechanism 200 is withdrawn; Moreover, through the flipping movement of the two cover plates 7, the caked microbial feed can be gathered towards the position of the feeding port 6, forming the function of automatic sampling and collection, which improves the convenience of sampling; It solves the problem that in the prior art, when the sampling device samples, it lacks the disturbance of the feed, resulting in the caked microbial feed that cannot move to the sampling area by itself through long-term storage, thereby reducing the sampling effect.

[0025] Touching blocks 85 are fixedly connected to both sides of the sliding frame 84, and both of the two touching blocks 85 extend to the outside of the control frame 4; Through the setting of the touching blocks 85, it is used to perform the telescopic movement of the sliding frame 84, and then drive the rotating shaft 81 to rotate through the connecting rod 83, forming the automatic unfolding or folding movement of the cover plate 7; Specifically, when the control frame 4 is inserted into the sampling frame 2, when the touching block 85 on the control frame 4 moves to the port of the sampling frame 2, with the continuous pushing of the control frame 4, the sampling frame 2 can squeeze the touching block 85, causing the touching block 85 to move, and then driving the cover plate 7 to extend through the sliding frame 84, forming the functions of automatic gathering and protection of the microbial feed, effectively utilizing the insertion force during sampling to achieve its automatic sampling function, and further improving the energy conservation and environmental protection performance of the sampling mechanism 200.

[0026] Guide posts 86 are fixedly connected to the outer surfaces of the two connecting rods 83, and elastic friction sleeves 87 are slidably sleeved on the outer surfaces of the two guide posts 86. Both of the two elastic friction sleeves 87 are fixedly connected to the inside of the control frame 4 through support rods; By fixedly connecting the guide posts 86 to the connecting rods 83 and slidably sleeving the elastic friction sleeves 87 on the guide posts 86, it is used to increase the resistance of the guide posts 86 during movement through the elastic friction sleeves 87, indirectly improving the stability after the cover plate 7 is unfolded or folded. This not only improves the sampling effect when the extraction frame 5 samples, but also can prevent the microbial feed from spilling after sampling.

[0027] Embodiment 3: Different from Embodiment 1; Refer to the appendix Figures 4 to 8, on both sides inside the movable frame 31, a collecting component 9 is arranged. The collecting component 9 includes a collecting plate 91 for collecting the microbial feed inside the storage tank 100 to the position of the extraction frame 5; Through the sector motion of the collecting plates 91 in the two collecting components 9, the microbial feed in the horizontal range of the sampling position can be collected to the position of the extraction frame 5. This not only facilitates the better entry of the microbial feed into the extraction frame 5 through the feed inlet 6, but also can collect the microbial feed at different positions in the horizontal range, further improving the diversity of the detection sampling collection; The collecting component 9 further includes a rotating shaft 92 rotatably connected to one side of the movable frame 31. The collecting plate 91 is fixedly connected to the rotating shaft 92 through a connecting frame 96. A gear 93 is fixedly connected to the outer surface of the rotating shaft 92, and a toothed plate frame 94 meshing with the outer surface of the gear 93 is arranged on the sealing baffle 32; By connecting the two toothed plate frames 94 to the two sealing baffles 32 respectively, when the two sealing baffles 32 form an unfolding movement under the extrusion driving force of the extraction frame 5 or the control frame 4, they can synchronously drive the two toothed plate frames 9 to move away from each other. Furthermore, they can drive the two gears 93 to rotate symmetrically, and finally drive the two collecting plates 91 to move in opposite directions through the rotating shaft 92 and the connecting frame 96, so as to drive the caked microbial feed inside the storage tank 100 to the position of the extraction frame 5, facilitating the better entry of the microbial feed into the extraction frame 5 through the feed inlet 6 to form the microbial feed sampling work; This not only effectively prevents the problem that the caking phenomenon occurs due to the long-term storage of the microbial feed inside the storage tank 10, thus affecting its sampling effect, but also effectively utilizes the driving force during sampling to form the function of automatic collection and sampling; The toothed plate frame 94 is slidably connected to the inside of the sealing baffle 32 in a sliding manner, and two stop blocks 95 are fixedly connected to the toothed plate frame 94; By connecting the toothed plate frame 94 to the sealing baffle 32 in a sliding manner and installing two stop blocks 95 on the toothed plate frame 94, it is convenient that after the sealing baffle 32 unfolds to a certain distance, it will touch one of the stop blocks 95, and the toothed plate frame 94 is driven by this stop block 95 to form the automatic unfolding work of the collecting plate 91; When the extraction frame 5 in the sampling mechanism 200 is inserted into the sampling frame 2, when it drives the two sealing baffles 32 to unfold, it will not drive the collecting plate 91. When the control frame 4 is inserted into the sampling frame 2 and the two sealing baffles 32 are fully unfolded by the sampling frame 2, it will drive the two collecting plates 91 in the two collecting components 9 to move in opposite directions to form the microbial feed collecting work, solving the problem that the collecting plate 91 starts to collect the microbial feed before the extraction frame 5 is fully inserted into the storage tank 100, thus affecting the subsequent collecting effect.
