[0002] Livestock generally refers to animals domesticated by humans, such as cattle, sheep, and pigs. Livestock feed can be divided into roughage, concentrate, and succulent feed. Feed sampling and testing is crucial for ensuring animal health, food safety, and improving livestock farming efficiency.

[0003] In contrast, patent publication number "CN220819484U" discloses a sampling device for testing dairy cow feed. By removing the sampling device and then rotating the drum, the storage tank can be removed. While this prevents direct contact with the feed, in actual use, the storage tank and sampling device are integrated, requiring disassembly after sampling is complete to remove the sample and then reinstall it, seriously affecting sampling efficiency. Accordingly, this application proposes a random sampling device for pig feed testing. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-4 A random sampling device for pig feed testing includes a random sampling device for pig feed testing, including a mounting plate 1, a motor 5 is fixedly installed above the mounting plate 1, and the motor 5 adopts a reciprocal bidirectional motor whose transmission shaft can rotate clockwise or counterclockwise, so that the screw rod 11 can rotate clockwise or counterclockwise, thereby making the adopting mechanism on the connecting plate 6 move up and down.

[0021] The mounting plate 1 is fixedly connected to the base 2 below, and the base 2 is "L" shaped. One side of the base 2 is fixedly connected to the slide rail 16, and a slide groove 9 is provided below the slide rail 16 and fixedly connected to one side of the base 2. The sampling box 10 is slidably connected to the two slide grooves 9, and the rack 17 is slidably connected to the slide rail 16. Four moving wheels 3 are fixedly installed below the base 2, which can enable the device to move so as to randomly sample at different places. Two fixed plates 8 are fixedly connected to one side of the base 2, and a slide rod 7 is fixedly connected to one of the fixed plates 8 below the mounting plate 1. The drive shaft of the motor 5 is fixedly connected to a screw rod 11, and the end of the screw rod 11 away from the motor 5 is fixedly connected to a gear 18 and rotatably connected to the fixed plate 8. A connecting plate 6 is slidably connected to the screw rod 11, and is also slidably connected to the slide rod 7. A sampling mechanism for sampling pig feed is provided on the connecting plate 6.

[0022] The sampling mechanism includes a push plate 4, two electric telescopic rods 14, three sampling cylinders 13, three piston rods 15, and three pistons 19. The three sampling cylinders 13 are respectively fixedly connected to the connecting plate 6, and the three pistons 19 are respectively attached to the inner walls of the three sampling cylinders 13. One end of the three piston rods 15 is fixedly connected to the piston 19. The push plate 4 is fixedly connected to the end of the three piston rods 15 away from the piston 19. One end of the two electric telescopic rods 14 is fixedly connected to the connecting plate 6, and the other end is fixedly connected to the push plate 4.

[0023] The maximum rising height of the connecting plate 6 is the middle of the screw rod 11, so as to prevent the push plate 4 from touching the base 2. The gear 18 is engaged with the rack 17, and a connecting rod 12 is fixedly connected to the bottom of the rack 17. The end of the connecting rod 12 away from the rack 17 is fixedly connected to a sampling box 10 for collecting the sampled feed.

[0024] When using this device, first push the device to the feed trough under the action of the moving wheel 3, then start the motor 5 to drive the screw 11 to rotate, so that the connecting plate 6 and the sampling mechanism are lowered, and at the same time the gear 18 rotates under the action of the screw 11, so that the rack 17 slides and drives the sampling box 10 to slide toward the base 2 through the connecting rod 12, so that the sampling box 10 is stored, leaving space for the sampling mechanism to take samples, and when the sampling tube 13 contacts the feed, start the electric telescopic rod 14 to make the push plate 4 drive the piston rod 15 to rise, so that the inside of the sampling tube 13 generates negative pressure under the action of the piston 19, and the feed is collected in the sampling tube 13, and then start the motor 5 to make the screw 11 rotate in the opposite direction. , so that the connecting plate 6 drives the sampling mechanism to rise, and at the same time, the gear 18 drives the rack 17 to make the sampling box 10 slide to the bottom of the sampling tube 13, and finally the electric telescopic rod 14 is started to make the push plate 4 press the piston rod 15, so that the piston 19 pushes the sampled feed from the sampling tube 13 into the sampling box 10. It is simple and convenient, avoiding manual removal of the sampling device to take out samples, which wastes time and affects the next round of sampling. It is also worth mentioning that since a certain interval is maintained between the three sampling tubes 13, the sampled feed can be kept random, avoiding sampling in one place affecting the test results. Finally, the pushing device moves to the next sampling point and samples can be taken according to the above steps, which is efficient and convenient.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
