[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Example 1

[0030] like Figure 1-5 A modular grain sampler 2 is shown, comprising: a support frame 1, several samplers 2 for dividing grain into two equal portions, and several receiving boxes 3 for receiving the divided grain; the samplers 2 and the receiving boxes 3 are detachably connected to the support frame 1; the support frame 1 has several first openings 11 for accommodating the samplers 2, two second openings 12 for accommodating the samplers 2 or the receiving boxes 3, four third openings 13 for accommodating the samplers 2 or the receiving boxes 3, and eight fourth openings 14 for accommodating the receiving boxes 3; the first openings 11, the two second openings 12, the four third openings 13, and the eight fourth openings 14 are symmetrically arranged on the support frame 1 from top to bottom.

[0031] Specifically, in the traditional grain sampling process, the grain needs to be placed in the sampler 2, which divides the grain into two equal parts. When the grain needs to be divided into four parts, the above process needs to be repeated: first, the grain is divided into two parts, and then each of the two parts is resampled into two parts, thus obtaining four equal grain samples. When the grain needs to be divided into eight parts, the staff needs to repeatedly place the grain in the sampler 2 and sample it seven times. When only 1 / 8 of the grain sample needs to be taken, the staff needs to repeat the sampling three times to obtain 1 / 8 of the grain sample. This sampling method is inefficient, and the repetitive work is prone to errors, leading to incorrect grain sampling results. Therefore, to address this situation, the present invention proposes a modular grain sampler 2, including a support frame 1. The support frame 1 has a first opening 11, a second opening 12, a third opening 13, and a fourth opening 14. The first opening 11 is used to place the sampler 2. When it is necessary to sample the grain, the sampler 2 is placed on the support frame 1 for grain sampling. The second opening 12 and the third opening 13 can be used to install either the sampler 2 or a receiving box 3, depending on the actual number of samples to be sampled. For example, when it is necessary to sample... When dividing grain into two portions, place the sampler 2 in the first opening 11, and then place the receiving box 3 in the two second openings 12. The grain collected by the sampler 2 will fall into the receiving box 3 below. When it is necessary to divide the grain into four portions, simply place the sampler 2 in the first opening 11 and the two second openings 12, and place the receiving box 3 in the four third openings 13. Then place the grain in the sampler 2 in the first opening 11 to divide the grain into four equal parts, which will fall into the four receiving boxes 3. Similarly, this invention can also divide grain into eight equal parts. Moreover, by installing receiving boxes in the openings of the support frame, grain can be divided into unequal quantities. For example, if it is necessary to obtain a 1 / 2 grain sample, a 1 / 4 grain sample, and a 1 / 8 grain sample, a first sampler can be installed in the first opening. At the same time, a first receiving box can be installed in one of the second openings, a second sampler can be installed in the other second opening, and a second receiving box and a third sampler can be installed in the two third openings corresponding to the second openings where the samplers are installed. Two third receiving boxes are placed at the bottom of the third samplers. In this way, a 1 / 2 grain sample can be obtained in the first receiving box, a 1 / 4 grain sample in the second receiving box, and a 1 / 8 grain sample in the two third receiving boxes. Similarly, those skilled in the art can obtain samples of other proportions of grain by any combination of arrangements, which will not be elaborated in this application.

[0032] Furthermore, such as Figure 4and Figure 5 As shown, the sample divider 2 includes: a receiving portion 21, a plurality of first inclined portions 22 and a plurality of second inclined portions 23; the first inclined portions 22 and the second inclined portions 23 have opposite inclination directions; the tops of the plurality of first inclined portions 22 and the tops of the plurality of second inclined portions 23 are connected to the bottom of the receiving portion 21; the number of first inclined portions 22 and the number of second inclined portions 23 are the same, and the widths of the first inclined portions 22 and the second inclined portions 23 are the same; the plurality of first inclined portions 22 and the plurality of second inclined portions 23 are arranged at intervals corresponding to each other at the bottom of the receiving portion 21.

[0033] Specifically, in order to evenly divide the grain into two portions, each receiver includes a receiving part 21 for receiving grain, including grain transferred from external equipment or grain that has fallen from the previous sampler 2. The first inclined part 22 and the second inclined part 23 are arranged alternately to evenly divide the grain that falls into the receiving part 21 into two portions.

[0034] Furthermore, the receiving part 21 includes a first side plate 211, a second side plate 212, a third side plate 213, and a fourth side plate 214. The first side plate 211, the second side plate 212, the third side plate 213, and the fourth side plate 214 are all inclined. One end of the first inclined part 22 is connected to the bottom edge of the second side plate 212, and one end of the second inclined part 23 is connected to the bottom edge of the fourth side plate 214.

[0035] Specifically, to prevent the grain from being stuck in the receiving part 21 after falling in and thus not falling out, the receiving part 21 of this invention has a flared design that is wider at the top and narrower at the bottom. Specifically, the inclination angles of the first side plate 211, the second side plate 212, the third side plate 213, and the fourth side plate 214 of the flared part all need to be greater than the rest angle or the free-flow angle of the grain. The rest angle refers to the angle between the inclined surface of the cone naturally formed by the grain falling from a high point and the horizontal line of the bottom surface. The free-flow angle indicates the sliding performance of a certain grain on a certain material. The angle of rest for wheat is 23°-38°, for barley it is 28°-45°, for corn it is 30°-40°, for rice it is 37°-45°, and for paddy rice it is 23°-33°. Therefore, to ensure the grains can smoothly slide down from the receiving part, the angles of the first side plate 211, the second side plate 212, the third side plate 213, and the fourth side plate 214 need to be greater than the grains' angle of free flow and angle of rest. This allows for more convenient catching of the grains falling into the receiving part 21, and the area of ​​the bottom opening of the receiving part 21 is the same as the area of ​​the top opening of the inclined part, ensuring that all the grains fall into the inclined part.

[0036] Furthermore, the first inclined portion 22 includes a fifth side plate 221, a sixth side plate 222, and a first bottom plate 223; the second inclined portion 23 includes a seventh side plate 231, an eighth side plate 232, and a second bottom plate 233; one side of the first bottom plate 223 is fixedly connected to the fifth side plate 221, the other side of the first bottom plate 223 is fixedly connected to the sixth side plate 222, and the top of the first bottom plate 223 is fixedly connected to the bottom edge of the second side plate 212; one side of the second bottom plate 233 is fixedly connected to the seventh side plate 231, the other side of the second bottom plate 233 is fixedly connected to the eighth side plate 232, and the top of the second bottom plate 233 is fixedly connected to the bottom edge of the fourth side plate 214.

[0037] Specifically, the top edge of the first base plate 223 is fixedly connected to the bottom edge of the second side plate 212, and the top edge of the second base plate 233 is fixedly connected to the bottom edge of the fourth side plate 214. This means that the first inclined part 22 and the second inclined part 23 completely occupy the bottom opening of the receiving part 21, so that the grain in the receiving part 21 can fall completely and without reservation from the inclined part without being stuck by the receiving part 21.

[0038] Furthermore, the edges of the second side plate 212 and the fourth side plate 214 are also provided with limiting posts 24 that can be slidably connected to the support frame 1, and the support frame 1 is provided with limiting grooves that can cooperate with the limiting posts 24.

[0039] The limiting groove allows the sampler 2 to slide in the opening, so that people can put the sampler 2 into the opening or pull the sampler 2 out of the opening.

[0040] Furthermore, the widths of the first inclined portion 22 and the second inclined portion 23 are 7mm-26mm.

[0041] Furthermore, to facilitate the removal of the sampler from the support frame 1, a handle 7 is provided on the sampler.

[0042] Specifically, the sampler 2 has 8-15 inclined sections. The more numerous and narrower the width of the first inclined section 22 and the second inclined section 23, the more uniform the sample distribution of the sampler 2. However, the width of the inclined sections varies depending on the type of grain. With a fixed length of the receiving section 21, when separating smaller grain particles, the width of the first inclined section 22 and the second inclined section 23 can be narrower, thus increasing the number of inclined sections. When the diameter of the particles to be sampled is larger, the width of the first inclined section 22 and the second inclined section 23 needs to be increased accordingly, which requires a corresponding reduction in the number of inclined sections to accommodate the length of the receiving section 21.

[0043] In summary, by setting a detachable sampler 2 on the support frame 1, the present invention can divide grain into several portions at once according to the actual grain sampling quantity needs. The sampling process is fast and does not require people to repeat the sampling operation, thus avoiding the possibility of operational errors caused by repeated sampling.

[0044] Other structures in Embodiment 1 are described in the prior art.

[0045] Example 2

[0046] Furthermore, such as Figure 2 As shown, as a further improvement to the present invention, in Embodiment 2, a modular grain sampler 2 further includes: a first support plate 4 for preventing grain from falling into the first inclined portion 22 and a second support plate 5 for preventing grain from falling into the second inclined portion 23. The first support plate 4 and the second support plate 5 are both slidably disposed on the support frame 1. The first support plate 4 is provided with spaced first spacer plates 41, and the second support plate 5 is provided with spaced second spacer plates 51. A plurality of first spacer plates 41 are inserted into a plurality of first inclined portions 22 in a one-to-one correspondence, and a plurality of second spacer plates 51 are inserted into a plurality of second inclined portions 23 in a one-to-one correspondence.

[0047] Furthermore, it also includes a weighing device (not shown in the figure) for weighing the grain in the sampler 2, the weighing device being fixedly mounted on the support frame 1.

[0048] Specifically, in the actual sampling process, the grain needs to be placed in the uppermost grain sampler 2 first, and then the grain in the sampler 2 is spread out evenly, so that the grain is evenly distributed in the sampler 2, avoiding the accumulation of grain in one part and resulting in uneven grain sampling. This requires a corresponding support plate at the bottom of the receiving part 21, so that the grain in the receiving part 21 can be evenly distributed before the grain falls from the inclined part. Therefore, the support plate is slidably mounted on the support frame 1, and the spacer plate on the support plate can be inserted into the opening between the inclined part and the receiving part 21 to prevent the grain from falling from the inclined part. Furthermore, a weighing device can weigh the grain in the sampler 2. Specifically, the sensor of the weighing device is connected to the support plate, and by sensing the pressure received by the support plate, it measures the weight of the grain in the sampler 2.

[0049] Example 3

[0050] As a further improvement to the present invention, such as Figure 2As shown in Embodiment 3, in a modular grain sampler 2, the support frame 1 further includes a first support 15, a second support 16, a third support 17, and a fourth support 18; the first support 15, the second support 16, the third support 17, and the fourth support 18 are all detachably connected; the first support 15 has a first opening 11; the second support 16 has two second openings 12; the third support 17 has four third openings 13; and the fourth support 18 has eight fourth openings 14.

[0051] Specifically, the present invention also provides another embodiment, that is, the support frame 1 is a split structure, and the sampler 2 is fixedly or detachably set on the support frame 1. During use, people can stack different support frames 1 in sequence according to actual needs, and achieve multi-level grain sampling through the combination of different modules.

[0052] Furthermore, such as Figure 2 and Figure 6 As shown, both the second support 16 and the third support 17 are equipped with partition plates 9 to prevent grain samples from crossing. This means that when grain samples fall downwards along the inclined section, they exhibit both longitudinal and lateral velocities. Therefore, to prevent grain samples from moving laterally into adjacent samplers or receiving boxes, partition plates 9 are placed between two adjacent samplers on the support to separate the grains. Since the third support has a relatively large number of partition plates and samplers, their distances are relatively close. When the distance between the sampler outlet and the partition plate 9 is close, a large amount of grain falling downwards can cause it to get stuck between the sampler outlet and the partition plate 9. Therefore, to address this situation, notches 6 need to be provided at the bottom of the first and second base plates of the sampler to allow the falling grain samples to fall directly downwards, preventing them from getting stuck between the outlet and the partition plate.

[0053] like Figure 2 As shown, in order to facilitate people to move the support frame, a handle 8 is provided on each side of the support frame for lifting the support frame.

[0054] Example 4

[0055] In Embodiment 1, the sampler has a uniform size, meaning each sampler can be used in the first, second, or third opening, thus improving its versatility. However, with samplers of the same size, as the quantity of grain is reduced through progressively smaller samples, the accuracy of the sampler may be affected due to insufficient precision. Therefore, in this embodiment, a grain sampler is further proposed, including a first sampler for placement in the first opening, a second sampler for placement in the second opening, and a third sampler for placement in the third opening. The first sampler and the first opening have the largest size. Similarly, the second sampler and the second opening have half the size of the first level, and the third sampler and the third opening have half the size of the second level. For example, when it is necessary to divide the grain into 8 portions of 50-gram samples, the size of the sampler needs to gradually increase from bottom to top. By progressively decreasing the size of the sampler, the sampling accuracy for small quantities of grain samples can be effectively improved, allowing for more precise division of grain into multiple samples.

[0056] This invention provides a modular grain sampler 2. According to the actual number of grain samples, a receiving box 3 or a sampler 2 can be placed on the support frame 1 to divide the grain into several equal parts as needed. This eliminates the need for staff to repeatedly use the sampler 2 to divide the grain, effectively improving the efficiency of grain sampling.

[0057] This invention is not limited to the above-described embodiments. If any modifications or variations to this invention do not depart from the spirit and scope of this invention, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this invention, then this invention also intends to include such modifications and variations.
