Description

Technical Field

[0001] The invention relates to the technical field of food detection and sampling, in particular to a metering cone used for food detection and sampling and a use method thereof. Background Art

[0002] Food testing and sampling is an important step in food quality control and safety testing. Scientific sampling methods can ensure the representativeness and accuracy of the test results. The purpose of food sampling is to extract a representative sample from a large number of foods in order to analyze its composition, quality, safety or compliance with relevant standards. Due to the wide variety of foods, sampling methods are also different. When sampling granular foods, a metering cone is required.

[0003] Chinese utility model patent CN218381717U discloses a metering cone for food detection and sampling, in order to solve the problem that the existing food sampling device cannot achieve quantitative sampling, resulting in low detection efficiency. The sampling barrel of this new type is divided into an upper part, a middle part and a lower part; wherein the upper part is a cylindrical structure, the middle part is a tubular structure, and the lower part is a conical structure; the support rod is fixed on the sampling barrel; the annular handle is arranged on the support rod; the piston is arranged inside the sampling barrel; the scale rod is provided with a scale, and the bottom end of the scale rod passes through the center hole of the top surface of the sampling barrel and is fixed on the piston inside the sampling barrel; the rotating rod is arranged at the center of the sampling hole in an axial connection; the circular plate is arranged inside the sampling barrel, and the bottom end of the rotating rod is arranged at the center of the circular plate in a rigid connection; at the same time, the circular plate is provided with an auxiliary hole that matches the sampling hole; the limit plate is used to limit the scale rod. The beneficial effect is to achieve quantitative sampling of food with high sampling accuracy.

[0004] The device still has problems in the actual sampling process. Specifically, when the metering cone is inserted into the grain pile by holding the ring handle and the rotating rod is adjusted to open the sampling hole to start sampling, the initial grain particles will enter the sampling area through the sampling hole. However, as the grain accumulates in the sampling area, the bottom will gradually block the sampling hole, resulting in the grain being unable to continue to enter the sampling area through the sampling hole. This blockage makes it impossible for the sampling area to collect grain according to the established amount, thus affecting the accuracy and completeness of quantitative sampling.

[0015] The present invention also provides a method for using a metering cone for food detection and sampling, comprising the following specific steps: S1. First, fix the bracket by hand, press the adjustment unit downward by hand to unlock the adjustment unit from the clamping slot, keep the adjustment unit in the pressed state, move the rotating rod downward as needed, and the rotating rod drives the adjustment plate to move downward, so that the adjustment plate gradually moves away from the tube cover to adjust the sampling area. According to the scale lines on the surface of the sampling tube, adjust the size of the sampling area to reach the required sampling amount, and then release the adjustment unit to position the adjustment plate; S2, then hold the bracket and insert the device into the pile of granular food to be sampled. After inserting to a suitable depth, first manually rotate the rotating rod through the knob for one circle, and drive the extrusion unit to move through the rotating rod. The corresponding sealing plate is pushed upward by the extrusion unit, and the flap is opened at the same time. At this time, the granular food enters the guide port through the sampling port and falls into the sampling area for sampling; S3. During the sampling process, the rotating rod is rotated periodically.

When the granular food fills the sampling area, the adjustment plate is limited. At this time, the rotating rod cannot be rotated, so it is clear that the maximum sampling value has been reached. At this time, the device is taken out of the granular food, the sampling head is manually rotated out of the sampling tube, the adjustment unit is pressed, the adjustment plate is unlocked, and it is pushed out of the sampling tube, so that the target sample in the sampling area can be taken out to complete the sampling of the food.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention rotates the rotating rod by turning the knob. When the rotating rod rotates, it will drive the secondary gear to rotate at the same time. The secondary gear drives multiple primary gears to rotate. The multiple primary gears drive the corresponding vibration seats to rotate. The vibration seat drives the vibration tube to move up and down through the limiting ball. The multiple vibration tubes drive the same adjustment plate to reciprocate up and down, which vibrates the granular food accumulated on the adjustment plate to prevent the accumulation and blocking of the sampling port position, affecting the sampling.

[0017] 2. The present invention rotates the rotating rod one circle, the rotating rod drives the secondary bevel gear to rotate, the secondary bevel gear drives multiple primary bevel gears to rotate, so that the multiple primary bevel gears rotate a quarter of a circle, the primary bevel gear drives the rotating rod to rotate, the rotating rod drives the guide block to rotate ninety degrees, so that the guide block rotates ninety degrees. During the rotation of the guide block, the sealing plate is first squeezed to drive it to move upward, so that the sealing plate is separated from the inside of the sampling port and is located above the tube cover, the granular food above the sampling port is periodically lifted, and the granular food is collected through the sampling port to prevent the granular food outside the collection port from being accumulated and fixed and unable to enter the sampling area, thereby further improving the sampling efficiency.

[0018] 3. In the present invention, the tooth plate is squeezed simultaneously during the process of squeezing the sealing plate, so that the tooth plate drives two rotating gears to rotate, and the two rotating gears respectively drive corresponding flaps to rotate, so that the flaps are rotated ninety degrees to open, and the granular food will enter the sampling area through the position of the flaps. When the sampling is completed, the tooth plate is reset by multiple reset springs, and the tooth plate drives the flaps to reset and seal, thereby sealing the sampling area, achieving the effect of sealing and protecting the sampled granular food.

[0039] With the above structure, four primary bevel gears 30 are installed in total and are perpendicular to each other. Two elliptical guide blocks 32 are installed on the surface of the rotating rod 31 connected to one side, which is convenient for guiding the sealing plate 35 and the tooth plate 38.

[0041] With the above structure, the partition 28 is convenient for isolating the primary bevel gear 30 and the secondary bevel gear 33 to prevent the sampled granular food from adhering to its surface and affecting its use during the sampling process. A bearing is installed in the stable mouth opened on the upper side of the bracket 3. The bearing has the same working principle as the bearing in the primary mounting hole, and the rotating rod 4 is slidably installed in the stable mouth through the bearing.

[0042] Furthermore, the surface of the rotating rod 4 is provided with scale lines.

[0043] With the above structure, the size of the sampling space can be easily adjusted through the scale lines.

[0044] Working principle: when the device is in use, first fix the bracket 3 by hand, press the adjusting slide bar 18 downward by hand, the slide bar 18 drives the connecting block 11 to move downward, and the connecting block 11 drives the multiple rebound rods 13 to rotate at the same time, and the multiple rebound rods 13 respectively drive the multiple moving blocks 14 to move, so that the multiple moving blocks 14 are close to each other with the connecting block 11 as the center, and the multiple moving blocks 14 respectively drive the corresponding clamping blocks 15 to disengage from the clamping groove 5, thereby unlocking the limit rod 8. At this time, keep the adjustment unit in a pressed state, move the rotating rod 4 downward as needed, and the rotating rod 4 drives the adjusting plate 6 to move downward, so that the adjusting plate 6 gradually moves away from the tube cover 7 to adjust the sampling area, and adjust the size of the sampling area according to the scale line on the surface of the sampling tube 2 to reach the required sampling amount, and then release the slide bar 18, and the slide bar 18 is reset by the elastic force of the clamping spring 19, so that the clamping block 15 is reinserted into the clamping groove 5, and the adjusting plate 6 is locked, thereby determining the size of the sampling area; The bracket 3 is held by hand and the device is inserted into the granular food pile to be sampled. After it is inserted to a suitable depth, the rotating rod 4 is first manually rotated one circle through the knob 16, and the rotating rod 4 drives the secondary bevel gear 33 to rotate, and the secondary bevel gear 33 drives multiple primary bevel gears 30 to rotate, so that multiple primary bevel gears 30 rotate a quarter of a circle, and the primary bevel gear 30 drives the rotating rod 31 to rotate, and the rotating rod 31 drives the guide block 32 to rotate ninety degrees, so that the guide block 32 rotates ninety degrees. During the rotation of the guide block 32, the sealing plate 35 is first squeezed to drive it to move upward, so that the sealing plate 35 is separated from the inside of the sampling port 36 and is located above the tube cover 7. In the process of squeezing the sealing plate 35, the tooth plate 38 is squeezed at the same time, and the tooth plate 38 drives the two rotating gears 37 to rotate, and the two rotating gears 37 respectively drive the corresponding flaps 34 to rotate, so that the flaps 34 rotate ninety degrees and open. At this time, the granular food will enter the sampling area through the position of the flaps 34, so as to be sampled. When the rotating rod 4 is rotating, it will simultaneously drive the secondary gear 24 to rotate, and the secondary gear 24 drives multiple primary gears 23 to rotate, and multiple primary gears 23 drive the corresponding vibration seats 25 to rotate. The vibration seat 25 drives the vibration tube 22 to move up and down through the limiting ball 27, and the multiple vibration tubes 22 drive the same adjustment plate 6 to reciprocate up and down, thereby vibrating the granular food accumulated on the adjustment plate 6 to prevent it from accumulating and blocking the sampling port 36 position and affecting the sampling.

[0045] During the sampling process, in order to ensure that the sampling port 36 is not blocked, it is necessary to periodically rotate the rotating rod 4 to make the adjustment plate 6 move up and down, and at the same time drive the sealing plate 35 and the flap 34 to reset up and down to prevent the granular food outside the collection port from accumulating and being unable to enter the sampling area. When the rotating rod 4 cannot be rotated, it means that the sampling is completed. At this time, the device is taken out of the granular food, the sampling head 1 is manually rotated out of the sampling tube 2, the slide bar 18 is pressed, the adjustment plate 6 is unlocked, and it is pushed out of the sampling tube 2, the target sample in the sampling area can be taken out, and the sampling of the food is completed.

[0046] The present invention also provides a method for using a metering cone for food detection and sampling, comprising the following steps: S1. First, fix the bracket 3 by hand, press the adjustment unit downward by hand to unlock the adjustment unit from the clamping groove 5, keep the adjustment unit in the pressed state, move the rotating rod 4 downward as needed, and the rotating rod 4 drives the adjustment plate 6 to move downward, so that the adjustment plate 6 gradually moves away from the tube cover 7 to adjust the sampling area, and adjust the size of the sampling area according to the scale lines on the surface of the sampling tube 2 to reach the required sampling amount, and then release the adjustment unit to position the adjustment plate 6; S2, then hold the bracket 3 and insert the device into the granular food pile to be sampled. After inserting to a suitable depth, first manually rotate the rotating rod 4 by the knob 16, and drive the extrusion unit to move by the rotating rod 4, and push the corresponding sealing plate 35 upward by the extrusion unit, and at the same time, the flap 34 is opened, and the granular food enters the guide port 29 through the sampling port 36 and falls into the sampling area for sampling; S3. During the sampling process, the rotating rod 4 is rotated periodically. When the rotating rod 4 rotates, it drives the driving unit to move, and the driving unit drives multiple vibration seats 25 to rotate. The vibration seat 25 drives the vibration tube 22 to move up and down through the limiting ball 27. The multiple vibration tubes 22 drive the same adjustment plate 6 to reciprocate up and down, vibrating the granular food accumulated on the adjustment plate 6 to prevent it from accumulating and blocking the sampling port 36, and at the same time drive the sealing plate 35 and the flap 34 to reset up and down to prevent the granular food outside the collection port from accumulating and being fixed and unable to enter the sampling area. When the granular food fills the sampling area, the adjusting plate 6 is limited. At this time, the rotating rod 4 cannot be rotated, so it is clear that the maximum sampling value has been reached.
