Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain purchasing and sampling technology, and in particular to a grain purchasing sampler. Background Technology
[0002] Grain sampling devices are tools used to take samples from grain piles or bags. These sampling devices are designed to obtain representative samples to assess grain quality and purchase value; common grain sampling tools capture grain samples by inserting a container into a grain pile or bag.
[0003] However, the lack of a limiting and protective structure during the piercing and sampling process of the grain bag will cause the opening at the piercing point of the grain bag to widen, which may lead to grain leakage during the subsequent unloading process. This has significant drawbacks in practical applications and makes it inconvenient for users to determine the piercing depth. When sampling is required at different locations, the sampling depth needs to be manually estimated, making it impossible to accurately grasp the sampling location and resulting in low efficiency.

[0026] like Figures 1-4 As shown, a grain sampling device includes a sampling tube body 1 and a spiked end 11. The spiked end 11 is fixedly connected to one end of the sampling tube body 1, and a rotating wheel 12 is provided at the other end of the sampling tube body 1. A spiral propulsion blade 13 is movably installed on the inner wall of the sampling tube body 1 near the spiked end 11. A connecting rod 14 is fixedly installed at one end of the spiral propulsion blade 13, passing through the sampling tube body 1 and fixedly connected to the rotating wheel 12. A sampling port 15 is opened on the outer side of the sampling tube body 1 near the spiked end 11. A discharge port 16 is provided on the outer side of the body 1 and near the end of the rotating wheel 12. A stabilizing plate 2 is sleeved on the outer side of the sampling tube body 1. Multiple support members 21, 22 are fixedly installed on the side of the stabilizing plate 2 near the spike end 11. Multiple sets of mounting grooves 3 are opened on the outer side of the sampling tube body 1 along its length. A limiting block 31 extending to the outer side is provided inside one of the mounting grooves 3. A first magnet 32 is fixedly installed at one end of the limiting block 31. A second magnet 33 that matches the first magnet 32 is fixedly installed at the bottom of the inner wall of the mounting groove 3.
[0027] like Figure 1 and Figure 2 As shown: The support member is a support nail strip 21, one end of which forms a pointed cone, and the end of the pointed cone is flat.
[0028] like Figure 3 As shown: The support member is a support strip 22, and one end of the support strip 22 forms a trapezoidal tip 23.
[0029] Specifically, the support nail strip 21 and the support strip plate 22 enable the stabilizing disc 2 to stably adhere to the surface of the grain bag, thereby improving the positional stability of the stabilizing disc 2.
[0030] like Figure 4 As shown: There are two sets of mounting slots 3, which are located on the upper and lower sides of the sampling tube body 1 respectively. Two arc-shaped plates 321 are provided on the outer side of the sampling tube body 1, and one end of the limiting block 31 is fixedly connected to the inner side of the arc-shaped plate 321.
[0031] Specifically: the contact surface between the arc plate 321 and the stabilizing disk 2 is larger than the contact surface between the limiting block 31 and the stabilizing disk 2, thereby improving the stability of the stabilizing disk 2 in limiting the position of the sampling tube body 1.
[0032] like Figure 1 As shown: A stabilizing sleeve 24 is fixedly installed on the side of the stabilizing disk 2 near the rotating wheel 12, and a reinforcing ring 241 fixedly connected to the stabilizing disk 2 is fixedly installed on the outside of the stabilizing sleeve 24.
[0033] Specifically, by limiting the position of the stabilizing sleeve, the effect of the stabilizing disk 2 on limiting the position of the sampling tube body 1 can be further improved, preventing the sampling tube body 1 from tilting. The reinforcing ring 241 can increase the structural strength of the stabilizing disk 2 and improve its durability.
[0034] like Figure 2 and Figure 3 As shown: Multiple anti-tilt pads 4 are fixedly installed at one end of the stabilizing disk 2.
[0035] Specifically, the anti-tilt pad 4 can further improve the stability of the contact between the stabilizing disc 2 and the grain bag.
[0036] Operating principle: First, determine the length that the sampling tube body 1 can penetrate according to the required sampling depth. Place the limiting block 31 into the matching mounting groove 3, and fix the limiting block 31 by the attraction of the first magnet 32 and the second magnet 33. Then, attach the stabilizing plate 2 to the surface of the grain bag to be tested. When the stabilizing plate 2 has a support nail strip 21 at one end, the pointed cone on one side of the support nail strip 21 presses against the surface of the grain bag and causes it to be partially concave, stabilizing the position of the stabilizing plate 2. Due to the planar design of the pointed cone, the grain bag can be prevented from breaking during compression. At this time, the sampling tube body 1 is inserted into the grain bag through the pointed end 11 through the stabilizing plate 2. When the sampling tube body 1 is inserted into the grain bag until the limiting block 31 contacts the stabilizing plate 2, the sampling tube body 1 cannot move further into the grain bag due to the obstruction of the limiting block 31 by the stabilizing plate 2. This position is the initially determined insertion depth, i.e., the sampling position, which helps the staff determine the insertion depth of the sampling tube body 1, making it convenient for the staff to take samples from different positions. Then, turning the rotating wheel 12 drives the connecting rod 14 to rotate, which in turn causes the spiral propulsion blade 13 to rotate, so that the grain inside the grain bag is transported through the sampling port 15 to the discharge port 16, thus realizing the sampling. After the sampling is completed, the sampling tube body 1 can be pulled out. During the process, the stabilizing plate 2 stabilizes the position of the sampling tube body 1, preventing accidental tilting and pulling of the grain bag's puncture site during insertion and extraction, thus enlarging the puncture site. Simultaneously, it ensures that the sampling tube body 1 does not shift during sampling, preventing further enlargement of the puncture site, thus protecting it. When a support plate 22 is provided at one end of the stabilizing plate 2, the contact area between the stabilizing plate 2 and the grain bag is further increased, further improving the stability of the stabilizing plate 2. The trapezoidal tip 23 at the end of the support plate 22 easily presses an indentation into the surface of the grain bag, facilitating the embedding of the support plate 22 into the indentation for stability, while also preventing... In case of accidental puncture of the grain bag surface; when an anti-tilt pad 4 is provided on one side of the stabilizing plate 2, the stability of the contact between the stabilizing plate 2 and the grain bag can be further improved; when an arc plate 321 is fixedly installed on one side of the limiting block 31, the limiting effect of the stabilizing plate 2 on the sampling tube body 1 can be further strengthened, and the use effect can be improved; when a stabilizing sleeve 24 is provided on one side of the stabilizing plate 2, the limiting effect of the stabilizing plate 2 on the position of the sampling tube body 1 can be further improved by the limiting effect of the stabilizing sleeve 24, and the position of the sampling tube body 1 can be prevented from tilting; when a reinforcing ring 241 is provided at the connection between the stabilizing plate 2 and the stabilizing sleeve 24, the structural strength of the stabilizing plate 2 can be increased and the durability can be improved.
