Technical Field

[0001] The utility model relates to the technical field of flour sampling devices, in particular to a flour sampling device for flour detection. Background Art

[0002] Flour is a powder made from wheat. It is the staple food in most parts of northern China. There are many varieties of food made from flour with different flavors.

[0003] In the process of flour production and processing, in order to ensure that the flour quality meets the corresponding standards, flour sampling and testing is required. At this time, flour sampling is required through a sampling device, which includes electric sampling devices and manual sampling devices. Among them, the stratified sampler is one of the commonly used manual sampling devices for flour sampling.

[0004] The stratified sampler is composed of two tightly fitting iron pipes or stainless steel pipes. One or several grooves are cut on one side of the outer pipe, and one or several grooves are cut on one side of the inner pipe accordingly. When sampling, the handle is used to rotate the inner and outer pipes to close the grooves, insert the material, rotate to open the groove, and close the groove when pulling out, and pour out the material to complete the operation.

[0005] The stratified sampler can realize efficient flour sampling, but when sampling, it is impossible to sample flour at different depths in the flour packaging bag separately, so the detection data of flour is not accurate enough. Based on this, a flour sampling device for flour detection is provided. Utility Model Content

[0039] The pin 202 is fixed to one end of the frontmost partition block 205 and passes through the front end of the conical head 102;

[0040] The discharge port 206 is provided on the lower surface of the inner rotating tube 201 and close to the rear end of the partition block 205. When the discharge port 206 rotates and moves to align with the through port 104, it is used to discharge the taken out waste;

[0041] Positioning components 3 are distributed inside the conical head 102 and outside the insertion pin 202. The positioning components 3 are used to determine the rotation position and movement position of the inner rotating tube 201.

[0042] The number of through-ports 104, sampling ports 204, partition blocks 205, and discharge ports 206 are all provided in multiple numbers and the numbers are the same, and the slot sizes of the through-ports 104 and the sampling ports 204 match;

[0043] The multiple partition blocks 205, the discharge port 206 and the multiple sampling ports 204 correspond one to one, and are used to achieve separate sampling of flour at different depths;

[0044] The positioning assembly 3 includes a rotating positioning hole 301, a moving positioning hole 302, a telescopic ball 303, and a telescopic spring 304;

[0045] There are two rotation positioning holes 301, which are distributed in a ring shape outside the pin 202, and there are multiple movable positioning holes 302, which are evenly distributed in the horizontal direction outside the pin 202 and are horizontally aligned with one rotation positioning hole 301;

[0046] The telescopic ball 303 is vertically slidably connected to the inner side of the conical head 102. A telescopic groove is formed inside the conical head 102 for the telescopic ball 303 to telescopically move. The telescopic spring 304 is distributed inside the telescopic groove and located on the top of the telescopic ball 303 to provide a reset power for the telescopic movement of the telescopic ball 303.

[0047] The telescopic ball 303 is inserted into the rotating positioning hole 301 to realize the horizontal alignment of the sampling port 204 and the through port 104 and the alignment or misalignment judgment in the circumferential direction;

[0048] The telescopic spring 304 is inserted into the movable positioning hole 302 to realize the alignment judgment between the discharge port 206 and the through port 104;

[0049] The two rotation positioning holes 301 are horizontally aligned with the sampling port 204 and the discharge port 206 respectively;

[0050] The number of the movable positioning holes 302 matches the number of the discharge openings 206 and the movable positioning holes 302 are horizontally aligned with the discharge openings 206 .

[0051] In this embodiment, when sampling the flour in the packaging bag, the inner rotating tube 201 can be inserted into the outer sleeve 101, and the front end of the insertion pin 202 protrudes from the front end of the box cone head 102. Then, the inner rotating tube 201 is rotated so that the sampling port 204 and the through port 104 are offset by 180 degrees along the circumferential direction. At this time, the telescopic ball 303 is stuck in a rotating positioning hole 301.

[0052] Then, the device is inserted into the packaging bag as a whole, and the insertion needle 202 and the conical head 102 can easily penetrate the packaging bag. When the multiple through holes 104 on the outer sleeve 101 completely enter the packaging bag, the inner rotating tube 201 can be rotated to rotate 180 degrees. At this time, the sampling port 204 and the through hole 104 are aligned along the circumferential direction and the horizontal direction, and the telescopic ball 303 is stuck in another rotating positioning hole 301. At this time, the flour in the packaging bag can fall into each sampling port 204.

[0053] Then, the inner rotating tube 201 is rotated 180 degrees, so that the sampling port 204 and the through port 104 are misaligned in the circumferential direction again (it should be noted that the discharge port 206 and the through port 104 are aligned in the circumferential direction at this time), and the sampled flour is stored in the inner rotating tube 201, and then the whole device is taken out of the packaging bag;

[0054] Then, a corresponding number of storage devices are taken according to the number of sampling ports 204, and then the flour inside each sampling port 204 is poured out in turn. The operation steps are as follows:

[0055] The inner rotating tube 201 is pulled horizontally to make the discharge port 206 approach the through port 104. At this time, the telescopic ball 303 shrinks and separates from the rotating positioning hole 301. When the telescopic ball 303 is aligned with the first movable positioning hole 302, the telescopic ball 303 is inserted into the first movable positioning hole 302 under the thrust of the telescopic spring 304. At the same time, the frontmost discharge port 206 is aligned with the through port 104. At this time, the flour inside the sampling port 204 corresponding to the discharge port 206 can be discharged.

[0056] Then, the inner rotating tube 201 is pulled again to make the telescopic ball 303 fit into the second movable positioning hole 302, and the second unloading port 206 is aligned with the corresponding through port 104, so that the flour inside the second sampling port 204 can be unloaded. This reciprocating operation can realize the separate unloading of flour inside multiple sampling ports 204, that is, synchronous and independent sampling of flour at different depths can be realized, so that the subsequent detection data is more accurate.

[0057] Please refer to Figures 1 to 4 , along the rear end direction of the inner rotating tube 201, the distance between the discharge port 206 and the corresponding sampling port 204 increases successively;

[0058] The horizontal distribution spacing of the rotating positioning hole 301 and the movable positioning hole 302 and the horizontal distribution spacing of two adjacent movable positioning holes 302 match the distribution spacing of the multiple groups of discharge ports 206 and sampling ports 204 one by one.

[0059] In this embodiment, the vibration generated by the telescopic ball 303 being inserted into the positioning hole can help the sampling personnel to quickly determine the positions of the sampling port 204 and the discharge port 206, so as to facilitate sampling and discharge.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
