[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Example:

[0025] See also Figures 1-4 The present embodiment provides a shallow sampling device for deep-layer feed storage, including a sampling barrel 1. A plurality of groups of external sampling ports 5 are provided on the outer wall of the sampling barrel 1 at equal intervals in the circumferential direction. Each group of external sampling ports 5 is provided with a plurality of sampling baffles 7 at equal intervals in the vertical direction. A plurality of internal sampling ports 8 are provided on the sampling baffle 7 at equal intervals in the vertical direction. The number of internal sampling ports 8 on the sampling baffle 7 is the same as the number of each group of external sampling ports 5 and the positions correspond one to one. A lifting assembly 4 is provided at the bottom of the sampling baffle 7. The lifting assembly 4 is used to drive the sampling baffle 7 to move in the vertical direction. A guide assembly 9 is provided between the sampling baffle 7 and the sampling barrel 1. A sampling baffle reciprocating assembly 7 is provided between the bottom of the sampling baffle 7 and the sampling barrel 1. The sampling tube 1 is provided with a sampling device cone 6 at the bottom. When in use, the sampling device is thrown down from the top of the warehouse. The sampling device is immersed in the feed or raw material by the gravity of the sampling tube 1 and the sampling device cone 6. At this time, the sampling baffle reset member pulls the sampling baffle 7 to move, so that the inner sampling port 8 is connected to the outer sampling port 5 at the corresponding position, and the feed or raw material enters the sampling tube 1 along the outer sampling port 5 and the inner sampling port 8. After the feeding is completed, the lifting component 4 is pulled, and the lifting component 4 drives the sampling baffle 7 to move upward, so that the inner sampling port 8 is staggered with the outer sampling port 5. The sampling baffle 7 closes the outer sampling port 5, and then the sampling device with completed sampling can be taken out of the warehouse through the lifting component 4 to complete the sampling. The operation is safe, convenient, easy to carry and highly practical.

[0026] Specifically, the size of the inner sampling port 8 is larger than the size of the outer sampling port 5, so that when the inner sampling port 8 is positioned opposite to the outer sampling port 5, it avoids blocking the outer sampling port 5, which helps the feed or raw materials to better enter the sampling tube 1; wherein, the distance between two adjacent inner sampling ports 8 on the sampling baffle 7 is larger than the size of the inner sampling port 8, so that when the inner sampling port 8 is staggered with the outer sampling port 5, the sampling baffle 7 can completely block the outer sampling port 5.

[0027] In this embodiment, if Figure 2 As shown, the lifting assembly 4 includes a sampling baffle cable 403 fixedly connected to the top of each sampling baffle 7, and each sampling baffle cable 403 is fixedly connected to the same connecting ring 402 at one end away from the sampling baffle 7, and a lifting cable 401 is also fixedly connected to the connecting ring 402. The lifting assembly 4 also includes a cable pulley 404, and the number of cable pulleys 404 is the same as that of the sampling baffle cables 403. The sampling baffle cables 403 pass around the cable pulley 404, and the cable pulley 404 is fixedly connected to the inside of the sampling tube 1 near the top. By pulling the lifting cable 401, the lifting cable 401 drives all the sampling baffle cables 403 to move upward along the cable pulley 404 through the connecting ring 402, and the sampling baffle cables 403 drive all the sampling baffles 7 to move upward synchronously, which is used to quickly cover the external sampling port 5 and is convenient to use.

[0028] Furthermore, if Figure 1 As shown, a wire sleeve 3 is fixedly connected to the top center of the sampling tube 1, and the top end of the lifting rope 401 passes through the wire sleeve 3 and extends to the outside of the sampling tube 1. The wire sleeve 3 is provided to improve the smoothness of the movement and pulling of the lifting rope 401.

[0029] In this embodiment, if Figure 3 and Figure 4 As shown, the sampling baffle reset member includes a tension spring 11, and the bottom of the sampling baffle 7 and the bottom end of the inside of the sampling tube 1 are fixedly connected with a tension spring fixing rod 12. The two ends of the tension spring 11 are respectively connected to the two tension spring fixing rods 12. The tension spring 11 is set to quickly reset the sampling baffle 7 when the sampling baffle 7 is not under force. When the tension spring 11 is in a stretched state, the inner sampling port 8 on the sampling baffle 7 is staggered with the outer sampling port 5. When the tension spring 11 is in a contracted state, the inner sampling port 8 on the sampling baffle 7 is correspondingly connected with the outer sampling port 5.

[0030] In this embodiment, if Figure 3 and Figure 4As shown, the outer cover of the tension spring 11 is provided with a protective cover 10, which is fixedly connected to the inner wall of the sampling tube 1. A through slot is provided on the top of the protective cover 10 for the sampling baffle 7 to pass through. The tension spring 11 is covered and protected by the protective cover 10 to prevent feed or raw materials from entering the tension spring 11, causing the tension spring 11 to be stuck and affecting its use. The length of the portion of the sampling baffle 7 placed in the protective cover 10 is greater than the distance the sampling baffle 7 moves, to prevent the sampling baffle 7 from detaching from the protective cover 10. The sampling baffle 7 can also close the through slot to prevent feed or raw materials from entering the protective cover 10 from the through slot.

[0031] In this embodiment, if Figure 3 and Figure 4 As shown, a limiting groove 701 is provided at the bottom of the sampling baffle 7 in the vertical direction, and a limiting column 13 is fixedly connected to the inside of the protective cover 10. One end of the limiting column 13 is slidably set in the limiting groove 701. When the sampling baffle 7 moves, the limiting column 13 moves in the limiting groove 701, thereby limiting the moving range of the sampling baffle 7 and preventing the sampling baffle 7 from moving too far. Among them, the length of the limiting groove 701 is greater than the size of the limiting groove 701.

[0032] In this embodiment, if Figure 2 As shown, both ends of the sampling baffle 7 are fixedly connected to a guide sleeve 901, and a guide rod 902 is slidably connected inside the guide sleeve 901. The bottom end of the guide rod 902 is fixedly connected to the protective cover 10, and the top ends of the two guide rods 902 are fixedly connected to the same fixed plate 903, and the fixed plate 903 is fixedly connected to the inner wall of the sampling tube 1. During the movement of the sampling baffle 7, the sampling baffle 7 slides on the guide rod 902 through the guide sleeve 901, which plays a role of limiting and guiding the sampling baffle 7, thereby improving the stability of the movement of the sampling baffle 7 and avoiding position deviation of the sampling baffle 7.

[0033] In this embodiment, if Figure 1 As shown, sampling covers 2 are rotatably connected to both sides of the bottom of the sampling tube 1, and handles are fixedly connected to the outer wall of the sampling cover 2. The handles are used to easily open the sampling cover 2 to observe or maintain the interior of the sampling tube 1.

[0034] In this embodiment, if Figure 1 As shown, the sampling device vertebra 6 is detachably connected to the sampling tube 1. The sampling device vertebra 6 is made of steel, iron or other materials and has a large gravity, which helps the sampling device to be immersed in the feed or raw materials. The detachable connection between the sampling device vertebra 6 and the sampling tube 1 can be a threaded connection, a bolt connection, etc. The bottom of the sampling tube 1 is open. After the sampling is completed, the sampling device vertebra 6 is disassembled and removed, which facilitates the quick pouring out of the feed or raw materials in the sampling tube 1.

[0035] Working principle: When in use, the sampling device is thrown down from the top of the bin by pulling the lifting rope 401. The sampling device is immersed in the feed or raw material by the gravity of the sampling tube 1 and the sampling device vertebra 6. At this time, the lifting rope 401 and the sampling baffle rope 403 are not under force, and the sampling baffle 7 is pulled down by the tension spring 11, so that the inner sampling port 8 on the sampling baffle 7 is connected to the outer sampling port 5 at the corresponding position. The feed or raw material enters the sampling tube 1 along the outer sampling port 5 and the inner sampling port 8. After the feeding is completed, the lifting rope 401 is pulled up. The lifting cable 401 drives all the sampling baffle cables 403 to move upward along the cable pulley 404 through the connecting ring 402, and the sampling baffle cables 403 drive all the sampling baffles 7 to move upward synchronously, so that the inner sampling port 8 and the outer sampling port 5 are staggered, which is used to quickly cover the outer sampling port 5. After taking out the sampling device, the sampling device vertebral body 6 is disassembled and removed, placed in the sampling tray, and the feed or raw material is poured out to complete the sampling. The device is safe and convenient to operate, easy to carry, and highly practical.

[0036] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
