Description

Technical Field

[0001] The utility model relates to the technical field of feed detection, in particular to a sampling device for feed toxin detection. Background Art

[0002] The main purpose of feed toxin testing is to determine whether feed contains mycotoxins that are harmful to animal health, such as aflatoxins, vomitoxin, zearalenone, and ochratoxin. These toxins not only affect animal health, growth performance, and reproductive performance, but may also pose a potential threat to human health through the food chain.

[0003] At present, when sampling for feed testing, although sampling tools can be used to take multiple samples of feed at different depths in the feed pile to increase sample diversity, for some tests, the purpose is to determine the average toxin content of the entire batch of feed, or to evaluate whether the feed meets specific quality standards, it is necessary to test the entire feed. If sampling tools are still used to take samples at different depths, the toxin content at different depths of the feed may be different due to factors such as ventilation and humidity during storage, resulting in one-sided test results. In addition, if comprehensive testing is to be performed, the feed samples at different depths sampled in the sampling tool need to be taken out one by one and remixed before testing, which is more troublesome.

[0004] Based on the above situation, we propose a sampling device for feed toxin detection to solve the above problems. Utility Model Content

[0005] The utility model provides a sampling device for detecting toxins in feed, which solves the problem in the prior art that it is inconvenient to conduct comprehensive detection on sampled feeds of different depths.

[0006] The technical problem solved by the present invention is achieved by the following technical solutions:

[0007] A sampling device for detecting toxins in feed, comprising an insertion tube with a hollow interior, a sealing member and a discharge member, wherein the insertion tube is used to be inserted into a feed pile, a plurality of sampling ports are axially opened on the insertion tube, and a sampling member is coaxially arranged inside the insertion tube, the sampling member is composed of a plurality of groups of sampling units, and the plurality of groups of sampling units are used to sample feeds of different depths, the sampling unit comprises a feed bin, a sealing bin and a discharge bin, the circumferential outer wall of the feed bin is sealingly and slidingly connected to the inner wall of the insertion tube, and the diameter of the sealing bin is small. The feed bin is provided with a feed port, the blocking piece is sealingly and slidingly connected to the inside of the blocking bin, and a plurality of blocking pieces are commonly connected to a pull rod having one end extending to the outside of the sampling piece. The discharge piece includes a first discharge pipe corresponding to the number of feed bins and a second discharge pipe provided at the bottom end of the sampling piece. The input end of the first discharge pipe is connected to the feed bin for separately discharging the feed inside the feed bins at different positions, and the second discharge pipe is used to discharge the feed in multiple feed bins together.

[0008] Preferably, the first discharge pipe includes a hard pipe connected to the feed bin and a soft pipe connected to one end of the hard pipe, and one end of the soft pipe extending to the outside of the insertion cylinder is threadedly connected to a cap.

[0009] Preferably, the blocking member is provided with a blocking rod for blocking the first discharge pipe, and the inner wall of the blocking bin is provided with a limiting member for limiting the blocking member. When the blocking member conflicts with the limiting member, the blocking rod releases the blockage of the first discharge pipe.

[0010] Preferably, the end of the blocking member close to the feed bin is a curved surface.

[0011] Preferably, a spring is connected between the bottom end of the sampling member and the insertion tube.

[0012] Preferably, the bottom end of the second discharge pipe is detachably connected to an insertion head, and the bottom ends of the insertion head and the insertion cylinder are both conical structures with the cone tips facing downward.

[0013] The beneficial effects of the present invention are as follows: by moving the sampling piece downward, the feed port is aligned with the sampling port, so that the feed enters the feed bin, and then by opening the cap, the feed in the feed bin can be discharged from different first discharge pipes respectively, so as to realize the separate discharge of feed of different depths, so as to carry out multi-point detection of feed in different parts, so as to more accurately understand the toxin status of feed at each specific position, and then the sealing piece can be pressed down to enter the lower feed bin, so that feed of different depths in multiple feed bins can be uniformly discharged from the second discharge pipe, so that they can be mixed and comprehensively tested later to obtain the average toxin level of the feed as a whole, reflecting the overall quality status of the entire batch of feed.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0023] Reference Figures 1-6 As shown, a sampling device for detecting toxins in feed includes an internal hollow insertion tube 1 for inserting into a feed pile. A sampling member 2 is coaxially provided inside the insertion tube 1. The sampling member 2 is composed of multiple groups of sampling units. The multiple groups of sampling units are used to sample feed at different depths. The sampling units include a feed bin 21, a blocking bin 22, and a discharge bin 23. The circumferential outer wall of the feed bin 21 is sealed and slidably connected to the inner wall of the insertion tube 1, and the diameter of the blocking bin 22 is smaller than the diameters of the feed bin 21 and the discharge bin 23. The feed bin 21 is provided with a feed port 201.

[0024] Specifically, when sampling feed, first insert the insertion tube 1 into the feed pile, determine the depth of insertion into the feed pile by the scale line on the insertion tube 1, and then press the sampling piece 2 downward to make the feed port 201 on the sampling piece 2 partially overlap or completely overlap with the sampling port 11. At this time, the feed can enter the feed bin 21 through the sampling port 11, so as to sample feed piles of different depths through multiple sampling ports 11 at different depths. Moreover, since the circumferential outer wall of the feed bin 21 is sealed and slidably connected with the circumferential inner wall of the insertion tube 1, the feed will not fall when entering the feed bin 21. To between the insertion tube 1 and the sampling piece 2, and in order to prevent the feed sample in the feed bin 21 from falling, a sealing piece 3 is also sealed and slidably connected in the blocking bin 22, and multiple blocking pieces 3 are commonly connected to a pull rod 31 with one end extending to the outside of the sampling piece 2. When the pull rod 31 drives multiple blocking pieces 3 to move into the lower feed bin 23, the blocking piece 3 no longer blocks the blocking bin 22. The feed sample in the feed bin 21 can enter the lower feed bin 23 through the feed bin 21. When the insertion tube 1 is in a vertical state, feed samples of different depths in the sampling unit from top to bottom will all fall downward.

[0025] Reference Figure 3-Figure 5 As shown, a discharge part is also included, which includes a first discharge pipe 4 corresponding to the number of feed bins 21 and a second discharge pipe 5 arranged at the bottom end of the sampling part 2. The input end of the first discharge pipe 4 is connected to the feed bin 21, and is used to separately discharge the feed inside the feed bin 21 at different positions. From top to bottom, feed samples of different depths in the sampling unit will fall into the second discharge pipe 5 to discharge the feed in multiple feed bins 21 together, that is, feed samples at different depths are collected separately through multiple first discharge pipes 4, and the second discharge pipe 5 can collect feed samples at multiple depths in a unified manner, which is more convenient and quick, and there is no need to take out multiple groups of feed samples one by one and then place them in a unified manner.

[0026] Reference Figure 1-Figure 5 As shown, further, the first discharge pipe 4 includes a hard tube 41 connected to the feed bin 21 and a hose 42 connected to one end of the hard tube 41, and the hose 42 extends to the outside of the insertion tube 1 and is threadedly connected to a cap 43. When the cap 43 of the first discharge pipe 4 at the corresponding position is opened, the feed in the feed bin 21 can be discharged through the first discharge pipe 4, so that the feed at different depths can be collected separately for subsequent testing, and when the sampling piece 2 moves upward in the insertion tube 1, the hose 42 will not hinder the range of movement of the sampling piece 2.

[0027] Reference Figure 5As shown, further, in order to prevent the feed from leaking from the first discharge pipe 4 after entering the feed bin 21, a blocking rod 32 for blocking the first discharge pipe 4 is further provided on the blocking member 3. The blocking rod 32 can be in an inverted "U" shape, and a limiting member 33 for limiting the blocking member 3 is provided on the inner wall of the blocking bin 22. When the blocking member 3 moves upward and conflicts with the limiting member 33, the blocking rod 32 moves out from the hard tube 41 of the first discharge pipe 4, releasing the blockage of the first discharge pipe 4. At the same time, the action of the limit member 33 can prevent the blocking member 3 from moving from the blocking bin 22 to the feed bin 21, causing the first discharge pipe 4 to discharge the feed and cause the feed to fall from the feed bin 21. When the blocking member 3 is located in the blocking bin 22 or the lower feed bin 23, it indicates that the feed bin 21 may be storing feed samples or the feed samples need to be discharged into the second discharge pipe 5, then the blocking rod 32 is located in the first discharge pipe 4 to prevent the feed from leaking from the first discharge pipe 4.

[0028] Furthermore, one end of the blocking member 3 close to the feed bin 21 is a curved surface. When the blocking member 3 moves downward into the lower bin 23, the curved surface structure at the upper end of the blocking member 3 can prevent feed from remaining at the upper end of the blocking member 3, allowing the feed to be discharged more thoroughly, thereby improving the accuracy of the next sampling work.

[0029] Reference Figure 2 As shown, further, a spring 6 is connected between the bottom end of the sampling piece 2 and the insertion tube 1. Under the elastic force of the spring 6, the sampling piece 2 can be driven to move upward to completely dislocate the feed port 201 and the sampling port 11. In this way, when the insertion tube 1 is inserted into the feed pile, the insertion tube 1 can be directly held with both hands without having to take away the sampling piece 2 separately, thereby avoiding the feed from entering from the feed port 201 and making it impossible to accurately sample the feed at a specific depth.

[0030] Furthermore, the bottom end of the second discharge pipe 5 is detachably connected to an insertion head 7, and the preferred detachable connection method is a threaded connection. After the insertion head 7 is removed, the feed can be discharged from the inside of the second discharge pipe 5, and the bottom ends of the insertion head 7 and the insertion tube 1 are both conical structures with the cone tip facing downward, which can be inserted into the interior of the feed pile more effortlessly.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
