Description

Technical Field

[0001] This utility model belongs to the field of feed testing technology, specifically relating to a sampling device for feed testing. Background Technology

[0002] Silage is one of the main feeds for ruminants. It is a biomodified feed made by chopping green fodder with a moisture content of 65%-75% and then anaerobically fermenting it with lactic acid bacteria in a closed, oxygen-deficient environment. Silage is characterized by its softness, juiciness, sour aroma, good palatability, and rich nutrition. Furthermore, because it is more durable than fresh feed, it can solve the problem of fresh forage scarcity in autumn and winter.

[0003] Silage can be stored in three ways: silage towers, heaps, and wrapped silage. Wrapped silage is the most widely promoted method. The silage material is wrapped in polyethylene plastic bags and stored for 1-2 months until it matures, at which point it can be fed to livestock. Wrapped silage offers flexible storage locations and is easy to operate.

[0004] For sampling wrapped silage, the common method is to make a cross on the surface of the wrapping bale and take samples at the center points of the four lines in sequence, with a sampling depth of 25cm-45cm from the wrapping bale.

[0005] During actual use, the inventors discovered that these prior art technologies have at least the following technical problems:

[0006] Existing technology requires selecting a point, inserting the sampler into the silage, removing it, and then tapping the sampling tube with a stick to make the silage fall into the collection bag. This process is repeated four times to complete the sampling of the wrapped silage. The entire operation is complicated and the sampling efficiency is low. Utility Model Content

[0007] To overcome the aforementioned shortcomings, the inventors of this utility model, through long-term exploration, experimentation, and continuous reform and innovation, have proposed a sampling device for feed testing, which can solve the problems of complex operation and low sampling efficiency in the existing technology for sampling wrapped silage.

The driving gear and the driven gear are disposed inside the mounting frame and mesh with each other. The mounting frame includes a horizontal frame and a vertical frame that are arranged crosswise and hollow inside. The driving gear is disposed at the center inside the mounting frame and is detachably fixedly connected to the output shaft of the motor. There are at least four driven gears, and the sampling tube is detachably fixedly connected to the driven gears.

[0009] A further preferred embodiment of the sampling device for feed testing according to the present invention is that the driven gear is arranged around the driving gear at 90-degree intervals.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the detailed description of the embodiments of this utility model provided below is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

[0030] Example 1:

[0031] like Figures 1 to 3 As shown, a sampling device for feed testing includes: a motor 1, a mounting frame 2, a sampling tube 3, a driving gear 4, a driven gear 5, a connecting tube 6, a scale line 7, a scraper 8, a chute 9, a slider 10, a retraction spring 11, a handle 12, a mounting base 13, a horizontal frame 21, and a vertical frame 22.

[0032] The mounting frame 2 includes a horizontal frame 21 and a vertical frame 22, which are arranged perpendicularly to each other. The interior of the horizontal frame 21 and the vertical frame 22 is hollow and is used to install the driving gear 4 and the driven gear 5.

[0033] The driving gear 4 is located at the center of the intersection of the mounting brackets 2. Four driven gears 5 are installed around the driving gear 4. The driven gears 5 mesh with the driving gear 4, and the four driven gears 5 are spaced 90 degrees apart from each other and are respectively located inside the horizontal frame 21 and the vertical frame 22.

[0034] The end of the motor 1 is fixedly mounted on the mounting frame 2 via the mounting base 13. The output shaft of the motor 1 passes through the mounting frame 2 and is detachably fixedly connected to the center of the drive gear 4. That is, when the motor 1 is turned on, it can drive the drive gear 4 to rotate, thereby driving the driven gear 5 to rotate.

[0035] The sampling tube 3 is a hollow cylindrical structure. Evenly spaced graduation lines 7 are arranged on the outer wall of the sampling tube 3 to facilitate observation of the sampling depth. The values ​​of the graduation lines 7 range from 25 cm to 45 cm. The top of the sampling tube 3 is detachably and fixedly connected to the driven gear 5 via a connecting tube 6. The top of the connecting tube 6 is fixedly connected to the axis of the driven gear 5, meaning that the rotation of the driven gear 5 drives the rotation of the connecting tube 6. The bottom of the connecting tube 6 has a cylindrical protrusion, and the top edge of the sampling tube 3 has a groove that matches the protrusion. Figure 3 As shown, the protrusion of the connecting tube 6 extends into the groove of the sampling tube 3 and rotates the sampling tube 3 to complete the snap-fit, that is, the rotation of the driven gear 5 can drive the sampling tube 3 to rotate.

[0036] The bottom end of the sampling tube 3 is used to drill into the silage. However, since the silage is compacted, the sampling tube 3 is not easy to drill into. To solve this problem, a serrated structure is set around the bottom of the sampling tube 3. When in use, it can be rotated to cut the grass and facilitate sampling inside the silage.

[0037] When the sampling tube 3 is inserted into the silage, the feed inside needs to be removed. However, during the insertion of the sampling tube 3, the feed inside is squeezed, making it difficult to remove. To solve this problem, this embodiment is provided with a chute 9, a slider 10, and a scraper 8. The chute 9 is arranged along the axial direction of the sampling tube 3. The slider 10 is slidably connected to the chute 9. The scraper 8 is arranged inside the sampling tube 3 and is fixedly connected to the slider 10. That is, when the slider 10 slides on the chute 9, it can drive the scraper 8 to move along the axial direction of the sampling tube 3, thereby extracting the silage.

[0038] Better, such as Figure 5 As shown, a contraction spring 11 is provided in the gap between the top surface of the scraper plate 8 and the inner wall of the sampling tube 3. One end of the contraction spring 11 is fixedly connected to the upper end of the scraper plate 8, and the other end is fixedly connected to the top surface of the inner wall of the sampling tube 3, so as to keep the scraper plate 8 in the state of being at the top of the sampling tube 3 in its natural state.

[0039] The grip 12 is vertically mounted on the mounting frame 2, making it easy to hold the mounting frame 2 by hand and control the direction and force during sampling.

[0040] In use, align the sampling tube 3 with the four preset sampling points, then start the motor 1 to drill the sampling tube 3 into the silage along the preset direction. After drilling to the specified depth, remove the sampling tube 3 along the original path. Then align the collection bag with the outlet of the sampling tube 3, move the slider 10 along the chute 9, and the scraper 8 will discharge the silage. Finally, seal the collection bag to complete the sampling.

[0041] Example 2:

[0042] like Figures 4 to 6 As shown, this embodiment 2 is a sampling device for feed testing based on embodiment 1. To solve the problem that the distance from the sampling tube 3 to the center of the mounting frame 2 cannot be adjusted, this embodiment has 12 driven gears 5 inside the mounting frame 2. The driven gears 5 are divided into first driven gears 51 and second driven gears 52, with 4 first driven gears 51 and 8 second driven gears 52. The first driven gears 51 are arranged around the driving gear 4 and mesh with the driving gear 4. The second driven gears 52 are installed in a straight line on the side of the first driven gears 51 away from the driving gear 4, and the second driven gears 52 mesh with each other. That is, when the driving gear 4 rotates, it drives the first driven gears 51 and the second driven gears 52 to rotate in sequence.

[0043] Four sampling tubes 3 are provided. The sampling tubes 3 are detachably fixedly connected to the first driven gear 51 and the second driven gear 52. Because there are 12 driven gears 5, the sampling tubes 3 can be installed in a suitable position according to the actual situation, thereby adjusting the distance between the sampling tubes 3 and the center of the mounting frame 2.

[0044] It should be noted that the driven gears 5 of this utility model can be not only 4 or 12, but also 8, 16, etc. By setting multiple driven gears 5, the range of movement of the sampling tube 3 can be increased, making it suitable for feed packages of different sizes.

[0046] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components.
