[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0049] Reference Figure 1-18 A grain sample divider includes: a multi-level dividing layer 1 arranged sequentially from top to bottom, and a bottom discharge layer 2; the number of dividing layers can be adjusted according to different testing requirements; as shown in the attached... Figure 3 In the design, after three layers of sample separation, the selected sample is led out through the discharge layer 2.

[0050] Preferably, the upper and lower ends of the sample layer 1 are provided with connecting plates; such as Figure 5 As shown, holes are made on the mating plate to insert bolts or other connecting parts to assemble the upper and lower layers together; in use, the number of layers in sample layer 1 is set according to the separation requirements and then assembled.

[0051] Preferably, the horizontal cross-section of the sample layer 1 is square; a central collection hopper 11 is provided in the sample layer 1 to gather the samples to be separated towards the center, so as to obtain a more uniform sample separation effect.

[0052] Meanwhile, the lower end of the central hopper 11 is equipped with a multi-channel sampling channel 3 composed of multiple equalizing plates 31.

[0053] The center position of the multi-channel sampling channel 3 corresponds to the center position of the central hopper 11, and both are located on the central axis of the discharge layer 2. After passing through the central hopper 11, the sample is dispersed from the center position by the equalization plate 31 and enters each sampling channel 3.

[0054] Understandably, with the setup of the central collection hopper 11 and the sample distribution channel 3, the sample forms a downward central flow when it is not obstructed; its flow rate is relatively fast and it is not prone to blockage.

[0055] It should be noted that multiple evenly distributed plates 31 are clustered together at the center, forming a surrounding array.

[0056] In addition, the outer wall of the sample layer 1 is provided with a sample outlet 4 corresponding to each sample channel 3, or it is closed; the sample outlet 4 is equipped with an inclined baffle 41 to block the sample and guide it to the outside, or the sample is allowed to pass downward without the baffle 41.

[0057] like Figures 7-10 As shown; after the sample is evenly divided, it enters the sample distribution channel 3 between the equalization plates 31; the baffle 41 passes through the sample outlet 4 and touches the equalization plate 31 inward, closing the sample distribution channel 3 and blocking the sample; at the same time, the sample is led out by its tilted state, so as not to block it.

[0058] Sampling layer 1 includes: four-layer and eight-layer; to meet common sampling needs.

[0059] like Figures 7-10 As shown; the four layers form four evenly distributed sampling channels 3.

[0060] like Figures 12-13 As shown; the eight layers form eight evenly distributed sampling channels 3.

[0061] Correspondingly, such as Figure 9 As shown; the four-layered outer wall is provided with two sample outlets 4 and baffles 41 are inserted; the sample passes downwards in two directions and is led to the outside in two directions.

[0062] Understandably, the two sample outlets 4 are spaced apart, so that the connected sample distribution channel 3 and the blocked sample distribution channel 3 are staggered, resulting in more uniform sample distribution.

[0063] like Figure 12 As shown; the outer wall of the eight layers is provided with six or eight sample outlets 4, and is equipped with insert baffles 41; forming three or seven paths for the sample to pass downwards, and the remaining paths to the outside.

[0064] It should be noted that in routine grain sample testing, 3 or 7 samples are retained according to the sample variety to meet the needs of imperfect grain testing. The remaining samples can be retained for bulk density and moisture testing. Therefore, the above description specifically mentions that the eight layers are controlled by baffle 41 to form three or seven downward paths for the sample; of course, other numbers of downward paths can also be formed by controlling baffle 41.

[0065] Furthermore, there are no special restrictions on the installation of baffle 41; a conventional structure within the field can be used.

[0066] For example, after insertion, bolts are used to secure it; Figure 17 , 18 As shown, an extension block is set below the sample outlet 4 in conjunction with the baffle 41; the baffle 41 and the extension block have corresponding openings; after the baffle 41 is placed in place, it is fixed with bolts.

[0067] Preferably, guide rails, support bars, and other structures can be provided on the side of the baffle 41 within the sample distribution channel 3 to guide and limit the insertion of the baffle 41.

[0068] In some embodiments, a central collecting hopper 11 is provided in the discharge layer 2, and the lower end of the central collecting hopper 11 is connected to a chute 21 extending to the outside.

[0069] like Figure 15 , 16 As shown, the sample remaining after the fractionation is discharged from the chute 21.

[0070] In some embodiments, it further includes: an outer casing 5;

[0071] The multi-stage sampling layer 1 and the discharge layer 2 are installed inside the outer casing 5;

[0072] The inner side of the outer box 5 forms a channel for the separated samples to fall.

[0073] Meanwhile, a first hopper 51 and a second hopper 52 are provided on both sides of the lower end of the outer box 5.

[0074] Correspondingly, such as Figure 2 , 3 As shown in Figure 4; the chute 21 extends through the outer box 5 to the position above the first hopper 51; the remaining sample after the sample separation falls into the first hopper 51.

[0075] like Figure 1 , 3 As shown in Figure 4; the inner bottom of the outer box 5 is provided with an inclined plate 53, and the side wall opening connects to the second hopper 52; the part of the sample that is guided to the outside of the sample layer 1 falls into the second hopper 52.

[0076] It should be noted that the side wall opening of the outer box 5 matches the lower end of the inclined plate 53.

[0077] Meanwhile, the second hopper 52 can be configured for side feeding or top feeding depending on its height.

[0078] like Figure 3 As shown, if the lower end of the inclined plate 53 is lower than the height of the second hopper 52, then an opening is provided on the side of the second hopper 52 corresponding to the opening on the side wall of the outer box 5 to form a channel; if the lower end of the inclined plate 53 is higher than the height of the second hopper 52, then the sample can enter from the top of the second hopper 52 after passing through the opening on the side wall of the outer box 5 (the top of the second hopper 52 needs to be in an open state).

[0079] In some embodiments, one or more sides of the outer casing 5 are provided with casing doors 54.

[0080] like Figure 1 ,2 As shown, the door 54 is opened to operate the baffles 41 of each sample layer 1; or maintenance, cleaning and other operations are carried out inside.

[0081] In some embodiments, the top of the multi-stage sample layer 1 is further provided with a sample inlet 6.

[0082] It should be noted that the sample inlet 6 is optional, mainly to obtain a larger sample placement space for easier operation; the lower end of the sample inlet 6 is connected to the top layer of the sample separation layer 1.

[0083] Preferably, the sample inlet 6 is equipped with a gate 61; and the gate 61 extends to the outside of the outer casing 5 for easy opening and closing.

[0084] It should be noted that the discharge layer 2 can be fixedly connected to the inner wall of the outer box 5 through structural components such as connecting rods and connecting plates (to minimize the impact on the sample falling), forming a stable assembly relationship between the two; each sample layer 1 is laid out layer by layer, and it is optional whether it is connected to the inner wall of the outer box 5.

[0085] Preferably, a gap is maintained between the lower end of the discharge layer 2 and the inclined plate 53 to avoid obstructing the sample; the discharge is smooth and leaves no residue.

[0086] Optionally, to better ensure stability, a thin rod is installed at the lower end of the discharge layer 2 as a support and fixed to the inclined plate 53; this has little impact on sample discharge.

[0087] This utility model is mainly used for the sampling of 500g small samples such as wheat, corn, and rice; it can shorten the sample sampling time, increase the number of daily inspections, and improve the overall inspection efficiency; it reduces the extra physical labor of inspection personnel; it has been applied to the autumn general survey inspection, and its design meets the normal use of inspection work, reduces the physical burden on inspection personnel, and greatly improves inspection efficiency.

[0088] This invention utilizes the "four-part sample division" principle to construct a three-level mixing structure, which occupies a small area and is ergonomically designed. It adopts a physical gravity flow method to ensure that the sample passes through evenly and is thoroughly mixed. The first two sampling layers divide the runoff sample into four equal parts, with two parts retained. The third sampling layer divides the runoff sample into eight equal parts, with three or seven parts retained depending on the sample type, which is sufficient for the inspection of imperfect particles. The remaining samples can be stored for bulk density and moisture testing.

[0089] This utility model allows for the free setting of the number of layers and can be disassembled at any time to meet different sample separation needs; it solves problems such as slow sample flow rate and uneven mixing; it can be used alone or added to an automatic sample separator.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
