Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of grain detection and relates to a sample divider. Background Art
[0002] Grain testing is an indispensable step for grain storage safety, and the sampler is an indispensable instrument in the grain testing process. During the grain testing process, the inspector needs to take a certain amount of samples from the grain warehouse or grain truck by sampling. The sample needs to be divided into two equal parts, one of which is used for subsequent various index tests, and the other is labeled and packaged for storage for later use as a reference.
[0003] The sample divider in the prior art generally includes a box body in the shape of a rectangular parallelepiped, a cube or other shapes, with grain outlets opened on both side walls of the box body, and a plurality of partitions 1 and 2 arranged in sequence along the length direction of the box body are fixed in the box body, wherein each partition 1 is bent to form a grain outlet channel 1 that is inclined downward toward one side of the box body and connected to the grain outlet, and each partition 2 is bent to form a grain outlet channel 2 that is inclined downward toward the other side of the box body and connected to the grain outlet, and the inlet ends of each grain outlet channel 1 and each grain outlet channel 2 are connected to the box opening of the box body.
[0004] However, the sample divider has great defects in use. For example, the amount of sample obtained is not fixed. When the sample weight is large, the container to be used is also larger, which causes the defect that the height of the sample divider cannot match the container. The sample divider often needs to be placed on a carrier for use, which is very inconvenient to operate. Secondly, during the sample dividing process, when the sample flows out from the outlet of the grain outlet channel 1 or the grain outlet channel 2, it is affected by the airflow and pressure, and the divided sample will scatter to the ground, causing unnecessary waste of the sample. Summary of the invention
[0005] The purpose of the utility model is to propose a sample divider in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is: how to avoid sample waste while improving the convenience of operation.
[0006] The purpose of the utility model can be achieved through the following technical solutions: a sample divider, comprising a partition assembly with a plurality of grain conveying channels 1 and a plurality of grain conveying channels 2 inside, characterized in that the sample divider also comprises a frame with a grain inlet on the top and a grain outlet hopper with two grain outlets on the bottom, the frame is provided with a guide portion arranged around the grain inlet and in a flared shape, the partition assembly is fixed in the frame and located directly below the grain inlet, the top of the partition assembly is affixed to and fixedly connected to the inner side surface of the guide portion, the grain outlet hopper is fixedly connected to the bottom of the partition assembly, the bottom wall of the grain outlet hopper is arched upward to form a partition assembly located between the two grain outlets and affixed to the bottom of the partition assembly, a plurality of grain conveying channels 1 are connected to one of the grain outlets, and a plurality of grain conveying channels 2 are connected to the other grain outlet.
[0007] Compared with the prior art, the advantage of the present sample divider is that the partition assembly is connected to the frame by a fixed connection, and the grain inlet, the partition assembly and the grain outlet hopper on the top of the frame are distributed vertically. When the user pours the grain sample obtained by sampling into the grain inlet on the top of the frame, the grain is roughly divided into two parts under the action of gravity, one part of which enters into each grain delivery channel 1 in the partition assembly along the guide part, and the other part enters into each grain delivery channel 2 in the partition assembly along the guide part. Due to the existence of the partition, the grain delivery channel 1 and one of the grain outlets are guided by one of the side walls of the partition, and the grain delivery channel 2 and the other grain outlet are guided by the other side wall of the partition. The guide is arranged so that the grain conveying channel 1 and one of the grain outlets, as well as the grain conveying channel 2 and the other grain outlet are in a facing state. When the sample is diverted and transported, the sample output by the grain conveying channel 1 or the grain outlet channel 2 can slide along the side wall of the partition. Under the premise of ensuring the sample transportation speed, the sample can be output from each grain outlet in a relatively stable state, so as to avoid the situation where the sample is scattered when it is output from the grain outlet, and effectively avoid sample waste. In addition, due to the setting of the frame, the height of the grain outlet can be increased, so that the sample divider can use a deeper container barrel, and there is no need to use it with a cushion block or a load-bearing platform, which effectively ensures that the preparation work before grain sampling is more convenient.
[0008] In the above-mentioned sample divider, several of the grain delivery channels 1 and several of the grain delivery channels 2 are arranged obliquely downward, the partition is in the shape of a cone, and the bottom of the grain outlet hopper has grain outlet pipes located on both sides of the partition and arranged obliquely downward, and the port of each grain outlet pipe is the grain outlet. Thus, a straight transition is achieved between the grain delivery channel 1, the outer wall of one side of the partition and one of the grain outlet pipes, and the outer wall of the other side of the partition of the grain delivery channel 2 and the other grain outlet pipe, and they are specifically arranged in an oblique downward manner, so as to ensure the sample conveying speed while ensuring that the sample is in a relatively stable state during the conveying process, and avoid scattering when output from the grain outlet.
[0009] In the above-mentioned sample divider, both sides of each grain outlet pipe shrink inward from top to bottom to make the grain outlet in a closed shape. This can guide the sample to a centralized position, so that the grain that originally slid along the inner wall of the grain outlet edge can converge to the middle of the grain outlet, thereby avoiding the situation where a small part of the sample is scattered and splashed, and effectively avoiding waste.
[0010] In the above-mentioned sample divider, the frame includes a horizontally arranged top plate, the grain feed port is rectangular and opened on the top plate, the top plate is provided with a flared guide portion around the grain feed port, the partition assembly includes a plurality of partition plates 1 forming the grain transport channel 1 internally and a plurality of partition plates 2 forming the grain transport channel 2 internally, each of the partition plates 1 located at the entrance of the grain transport channel 1 and each of the partition plates 2 located at the entrance of the grain transport channel 2 has a triangular welding portion, and each of the welding portions is adhered to and fixedly connected to the inner side surface of the guide portion. The existence of the guide part can guide the samples entering the sample divider from the grain inlet, so that during the transition process of the samples input from the grain inlet to each grain conveying channel one or each grain conveying channel two, under the action of the guide part, the input samples can slide to each grain conveying channel one or each grain conveying channel two in a relatively stable state, and there is a straight transition between the aforementioned grain conveying channel one, one side outer wall of the partition and one of the grain outlet pipes, and the other side outer wall of the partition of grain conveying channel two and the other grain outlet pipe, so that the samples are in a relatively stable state during the entire transportation process, thereby avoiding the situation where a small number of samples are scattered and splashed, and effectively avoiding waste.
[0011] In the above-mentioned sample divider, the top plate is arranged horizontally, and the frame body further comprises side plates fixed vertically at both ends of the top plate, wherein one of the grain outlet pipes is arranged protruding from one side of the two side plates, and the other grain outlet pipe is arranged protruding from the other side of the two side plates. Through this arrangement, it is ensured that when the sample is divided, the grain outlet pipe can be arranged closer to or even extend into the container barrel, so as to prevent the sample from scattering and splashing on the ground during the transportation process.
[0012] In the above sample divider, the frame body further comprises a bottom plate, which is fixed between the two side plates and arranged near the lower ends of the side plates, thereby improving the structural strength of the frame body as a whole and ensuring the stability of the frame body.
[0013] In the above-mentioned sample divider, a handle is fixed on the outer wall of the top of each side plate, so as to facilitate the position movement of the sample divider.
[0014] Compared with the existing technology, this sample divider has the following advantages:
[0015] 1. The frame is used as the main support to ensure the placement stability of the sample divider while improving the position of its grain outlet. It does not need to be equipped with a carrying platform for use, which improves the convenience of operation. The partition cooperates with the grain outlet and the grain delivery channel 1 and the grain delivery channel 2 to ensure that the sample delivery speed is guaranteed. The sample can be output from each grain outlet in a relatively stable state to avoid the situation where the sample is scattered when it is output from the grain outlet, effectively avoiding sample waste.
[0016] 2. Set the grain outlet of the grain outlet pipe to be closed to prevent a small amount of sample from splashing around and effectively avoid waste.
[0017] 3. Through the setting of the guide part, the sample can be kept in a relatively stable state during the entire transportation process, so as to avoid the scattering of a small number of samples and effectively avoid waste. BRIEF DESCRIPTION OF THE DRAWINGS

The expansion-shaped guide portion 211, the partition assembly 1 specifically includes a plurality of partition plates 13 and a plurality of partition plates 14. Specifically, each partition plate 13 and each partition plate 14 are square in the original state, and the two sides are folded inward along the diagonal direction, so that a diversion channel 1 is formed inside each partition plate 13, and a diversion channel 2 is formed inside each partition plate 14. In addition, the plurality of partition plates 13 and the plurality of partition plates 14 are alternately arranged in sequence along the length direction of the grain inlet 21, and the plurality of partition plates 13 and the plurality of partition plates 14 are radially symmetrically arranged, such as Figure 3 and Figure 6 As shown, the upper end of each partition plate 13 and each partition plate 2 14 has a triangular welding portion 4, and each partition plate 13 and each partition plate 2 14 are welded and fixed to the lower side edge of the guide portion 211 through the welding portion 4, and each diversion channel 1 and each diversion channel 2 are arranged in an inclined state.
[0028] like Figure 6As shown, the grain hopper 3 is in the shape of a rectangular cylinder, and the outer walls of the tops of its two ends are connected with long strip-shaped connecting plates by screwing or welding. At the same time, on the partition component 1, the outer walls of the partition 13 at one end and the partition 2 14 at the other end are connected with long strip-shaped mounting plates by screwing or welding. The mounting plates are overlapped with the connecting plates one by one, and the two are locked by screws, so that the grain hopper 3 is fixedly connected to the bottom of the partition component 1. The center of the inner bottom wall of the grain hopper 3 is arched upward along the length direction to form a conical partition part 32, and the partition part 32 is specifically connected to the lower end of the partition component 1 (each partition 1 3 and each partition plate 2 14) are fitted so that a plurality of grain delivery channels 1 are directly opposite to one of the grain outlets 31, a plurality of grain delivery channels 2 are directly opposite to the other grain outlet 31, and among the two grain outlet pipes 33, one of the grain outlet pipes 33 protrudes from the frame body 2 from one side of the two side plates 23, and the other grain outlet pipe 33 protrudes from the frame body 2 from the other side of the two side plates 23.

Under the guidance of the guide part 211, the sample passes through the grain inlet 21 and enters the grain delivery channel 1 11 or the grain delivery channel 2 12 under the action of gravity. The partition component 1 roughly divides the sample into two parts of similar mass. The samples obtained after the two parts are diverted are guided by the outer wall of the partition part 32 and then enter the two grain discharge pipes 33 accordingly. The samples are guided by the closed inner wall at the grain discharge port 31 and then output to the two container barrels respectively.
