As shown in fig. 1 and 2, in the present embodiment, illustratively, the inner diameter of the first tube body 110 may be equal to the outer diameter of the second tube body 210, and the second tube body 210 may be coaxially disposed within the first tube body 110 and rotatably disposed, such as the second tube body 210 being in clearance fit with the first tube body 110. The ends of the first and second pipes 110 and 210 for insertion into the heap or pit may be defined as bottom ends and the other end may be defined as top ends.

Then, the first tube 110 and the second tube 210 disposed in the first tube 110 are driven to rotate, so as to scrape the fermented grain sample into the inner sampling area 212 through the two sides of the outer sampling port 111 and the inner sampling port 211. The second tube 210 is driven to rotate in the first tube 110 by rotating the handle 220, so as to rotate the inner sampling area 212 to the outer sampling port 111 and form a closed sampling bin around the outer sampling area 112, so that the fermented grain sample is in the sampling bin, and the state shown in fig. 3 is referred to.

It can be appreciated that, the fermented grain sampler that this application provided, it is after accomplishing the sampling to the fermented grain sample, and before taking out the fermented grain sample from the fermented grain sampler, the fermented grain sample can be in confined sample storehouse all the time, therefore the fermented grain sample is difficult for receiving interference and pollution in the sampling process, can ensure the accuracy and the representativeness of sampling.

Specifically, the outer tube 100 further includes a handle 120, the handle 120 being disposed at an end of the first tube body 110 remote from the outer sampling region 112.

As shown in fig. 2, in the present embodiment, illustratively, the handle 120 may be provided in a round bar shape, which may be provided at a top end of the first tube 110, and may be fixedly connected with an end of the first tube 110. The handle 120 may be perpendicular to the first tube 110, and one end of the top of the first tube 110 may be fixedly connected to the middle of the handle 120, so as to form a T shape.

Of course, in some embodiments, one end of the handle 120 may be fixedly connected to one end of the top of the first tube 110, so as to form an "L" shape.

It can be appreciated that by holding the handle 120, the fermented grain sampler can be conveniently inserted into the pile-up fermentation pile or pit, and simultaneously, the first pipe body 110 and the second pipe body 210 arranged in the first pipe body 110 can be conveniently driven to rotate when the fermented grain sampler is inserted into the pile-up fermentation pile or pit, so that the purposes of saving more labor and more accurate sampling are achieved.

Specifically, the first tube body 110 is provided with a clamping groove 113 in the circumferential direction, and the rotation handle 220 passes through the clamping groove 113 and is slidably disposed within the clamping groove 113.

As shown in fig. 1 to 3, in the present embodiment, it is exemplarily illustrated that the clamping groove 113 may be provided at a top end of the first pipe body 110 and penetrate through a sidewall of the first pipe body 110 in a circumferential direction of the first pipe body 110. The rotating handle 220 passes through the clamping groove 113 and is slidably disposed in the clamping groove 113, and rotates around the axis of the first tube 110 and the second tube 210 during sliding, and simultaneously drives the second tube 210 to rotate.

It can be appreciated that by providing the clamping groove 113 and slidably disposing the rotary handle 220 in the clamping groove 113, the clamping groove 113 can guide and limit the rotation of the rotary handle 220, so that the rotary handle 220 and the second pipe 210 are more stable in rotation, and the second pipe 210 is not easy to move along the axial direction thereof.

Specifically, a first conical head 114 is disposed at an end of the first tube 110 near the outer sampling area 112, and a second conical head 213 is disposed at an end of the second tube 210 near the first conical head 114.

As shown in fig. 2 and 3, in the present embodiment, it is exemplarily illustrated that the first pipe body 110 is close to one end of the outer sampling region 112, that is, the bottom end of the first pipe body 110, and thus the first cone head 114 is disposed at the bottom end of the first pipe body 110. The first cone 114 may include a large end and a small end, where the large end of the first cone 114 is close to the first pipe 110, and the small end is far from the first pipe 110 and forms a cone tip. And, likewise, the second tap 213 is also provided at the bottom end of the second pipe 210, and its structure may be similar to that of the first tap 114.

It can be appreciated that, in this embodiment, by providing the first cone 114 and the second cone 213 on the first pipe 110 and the second pipe 210 respectively, the resistance of the first pipe 110 and the second pipe 210 when they are inserted into the pile fermentation pile or pit can be reduced, so as to further achieve the purposes of saving effort and being convenient.

More specifically, the outer sampling port 111 is disposed along the axial direction of the first pipe body 110, the outer sampling region 112 extends to the first conical head 114, the inner sampling port 211 is disposed along the axial direction of the second pipe body 210, and the inner sampling region 212 extends to the second conical head 213.

As shown in fig. 1 and 2, in the present embodiment, it is exemplarily illustrated that the outer sampling port 111 and the inner sampling port 211 are respectively extended from the bottom ends of the first pipe body 110 and the second pipe body 210 toward the middle portions of the first pipe body 110 and the second pipe body 210, and when extended, the outer sampling port 111 and the inner sampling port 211 respectively cut the first cone head 114 and the second cone head 213 so that the outer sampling region 112 and the inner sampling region 212 can be respectively extended to the first cone head 114 and the second cone head 213.

It can be appreciated that, in this embodiment, by extending the outer sampling region 112 and the inner sampling region 212 to the first cone head 114 and the second cone head 213, respectively, a portion of the fermented grains can enter the inner sampling region 212 of the first pipe body 110 along the axial direction of the first pipe body 110 and the second pipe body 210 during the process of inserting the fermented grain sampler into the pile fermentation pile or pit; and then, the part of fermented grains can be scraped into the inner sampling area 212 through the side walls of the outer sampling port 111 and the inner sampling port 211 by rotating the first pipe body 110, so that the embodiment can ensure that enough fermented grains can be sampled into the sampling bin.

Specifically, the second tube 210 is provided with a partition 214 at the top side of the inner sampling region 212, and the partition 214 partitions the space of the inner sampling region 212 and the second tube 210 above the top of the partition 214.

As shown in fig. 2 and 4, in the present embodiment, it is exemplarily illustrated that the partition 214 may be provided in a plate shape, which may be fixedly coupled with the inner sidewall of the second pipe body 210. It should be noted that, the partition 214 may be horizontally disposed or may be obliquely disposed, but it is required to ensure that the space above the top of the partition 214 is partitioned between the inner sampling region 212 and the second pipe 210; in this embodiment, the partition 214 provided obliquely will be described as an example. In this embodiment, the partition 214 may be disposed on a side of the inner sampling area 212 away from the second cone 213, so that the fermented grain sample may be just located in the inner sampling area 212 during sampling.

It can be appreciated that, in this embodiment, by providing the partition portion 214, the fermented grain sample is not easy to randomly move when temporarily stored in the sampling bin, for example, moves to the middle upper portion of the second pipe 210, so that the fermented grain sample can be taken out conveniently, and the fermented grain sample is not easy to be polluted, and meanwhile, the first pipe 110 and the second pipe 210 can be cleaned conveniently.

Specifically, the clamping grooves 113 are provided in a first position and a second position along both ends of the first tube body 110 in the circumferential direction, respectively;

wherein, when the rotary handle 220 is slid to the first position, the inner sampling region 212 rotates to the outer sampling region 112 and the sampling bin is fully opened at the outer sampling port 111;

when the rotary handle 220 is slid to the second position, the inner sampling region 212 rotates to the outer sampling port 111 and encloses with the outer sampling region 112 to form a closed sampling chamber.

As shown in fig. 1 and 3, in the present embodiment, it is exemplarily illustrated that the rotation handle 220 may be provided in a circular rod shape, and the unfolded shape of the catching groove 113 on the sidewall of the first pipe body 110 may be provided as a waist-shaped hole, and the width of the waist-shaped hole may be equal to the diameter of the rotation handle 220. At this time, both ends of the clamping groove 113 along the circumferential direction of the first pipe body 110 are semicircular, and the first position and the second position may be the centers of the two ends of the clamping groove 113 along the circumferential direction of the first pipe body 110 respectively. By driving the rotary handle 220 to slide back and forth along the circumferential direction of the first tube 110 in the clamping groove 113, the rotary handle 220 can be switched between the first position and the second position.

As shown in fig. 1, in the present embodiment, since the second tube 210 rotates synchronously with the rotating handle 220, the rotation angle of the inner sampling region 212 is the same as that of the rotating handle 220. When the rotary handle 220 is located at the first position, the inner sampling area 212 rotates to the outer sampling area 112 and is completely overlapped with the outer sampling area 112, so that the sampling bin is completely opened at the outer sampling port 111, and further, the fermented grain sample is conveniently introduced into the sampling bin. It should be noted that when the radians of the inner sampling region 212 and the outer sampling region 112 are equal, the "complete overlapping" is understood to mean that the two sides of the inner sampling region 212 and the outer sampling region 112 are located on the same axial section of the first tube 110 and the second tube 210, and the axial section is a section passing through the axes of the first tube 110 and the second tube 210. When the curvature of the inner and outer sampling regions 212, 112 is unequal, "fully overlapping" may be understood as the one of the inner and outer sampling regions 212, 112 having the smaller curvature being located inside the one having the larger curvature.

As shown in fig. 3, when the rotary handle 220 rotates from the first position to the second position, the inner sampling area 212 rotates along with the rotary handle 220 and rotates to the outer sampling port 111 to form a closed sampling bin around the outer sampling area 112, so that the fermented grain sample obtained by sampling is temporarily stored in the sampling bin.

As shown in fig. 1, after the fermented grain sampler is taken out, the rotating handle 220 may be further driven to rotate again, so that the rotating handle 220 returns to the first position again, and the sampling bin is fully opened again, so as to take out the fermented grain sample conveniently.

It can be appreciated that, in this embodiment, the first position where the sampling bin is completely opened and the second position where the sampling bin is enclosed to form the closed sampling bin are set, so that the rotation handle 220 is easier to rotate in place during the sampling process or the taking out of the fermented grain sample, thereby improving the convenience during the sampling process or the taking out of the fermented grain sample.

More specifically, the outer sampling region 112 has an arc of 180 degrees or more in the circumferential direction of the first pipe body 110, and the inner sampling region 212 has an arc of 180 degrees or more in the circumferential direction of the second pipe body 210.

As shown in fig. 1 and 3, in this embodiment, when the inner sampling area 212 and the outer sampling area 112 are enclosed to form a closed sampling bin, if the radian is smaller than 180 degrees, a gap exists between the inner sampling area 212 and the outer sampling area 112, and the fermented grain sample is caused to be spilled from the gap. When the radians of the outer sampling area 112 and the inner sampling area 212 are equal to or greater than 180 degrees, the inner sampling area 212 and the outer sampling area 112 can effectively enclose to form a closed sampling bin, so as to ensure the sealing effect of the sampling bin.

In this embodiment, the arc of the inner sampling region 212 may be slightly smaller than the arc of the outer sampling region 112, and the inner sampling region 212 may be located in the outer sampling region 112 when the sampling bin is fully opened. For example, the outer sampling region 112 may have an arc of 185 degrees and the inner sampling region 212 may have an arc of 183 degrees. While the rotation angle of the rotation handle 220 may be just 180 degrees. When the rotary handle 220 is in the second position, the side walls of the two sides of the inner sampling region 212 and the outer sampling region may still partially overlap to further enhance the sealing effect of the sampling cartridge.

Specifically, the first tube 110 is provided with graduations.

As shown in fig. 1 to 3, in the present embodiment, illustratively, the scale may be used to indicate the depth of insertion of the fermented grain sampler into the pile or pit, and may include a first scale and a second scale. The first scale and the second scale may be different positions in the axial direction of the first pipe body 110, for example, the first scale is set to be relatively small and set to be 1.2 meters; the second scale is set relatively large and is set to 1.5 meters.

In some embodiments, the first scale and the second scale may also be set to other values.

In other embodiments, the scale may further include a third scale, a fourth scale, a fifth scale, and the like.

It can be understood that the scale can sample the accuracy of the position when sampling is performed by the fermented grain sampler.

Specifically, the fermented grain sampler is made of stainless steel.

In this embodiment, it is exemplarily illustrated that the fermented grain sampler may be made of 304 stainless steel, which has good corrosion resistance and heat resistance, and has good hot workability such as stamping and bending, no heat treatment hardening phenomenon, good workability and weldability, and is not easy to pollute the fermented grains.

The implementation principle of the fermented grain sampler provided by the embodiment of the application is as follows:

when the fermented grains are sampled, the rotary handle 220 is rotated to the first position, and the rotary handle 220 drives the second pipe body 210 to synchronously rotate in the first pipe body 110, so that the inner sampling area 212 rotates to the position of the outer sampling area 112, and the sampling bin is opened at the outer sampling port 111. Pressure is then applied to the fermented grain sampler by the handle 120 to insert the fermented grain sampler into the pile or pit to a designated depth. When the fermented grain sampler is inserted, the first cone head 114 and the second cone head 213 can reduce resistance. And then the handle 120 drives the first tube 110 to rotate, so that the fermented grain sample is scraped into the inner sampling area 212 of the second tube 210 through the side wall of the outer sampling port 111 of the first tube 110 and the side wall of the inner sampling port 211 of the second tube 210. Then, the rotary handle 220 is rotated from the first position to the second position, and when the rotary handle 220 rotates, the second pipe body 210 is driven to synchronously rotate in the first pipe body 110, so that the inner sampling area 212 rotates to the outer sampling port 111 and forms a closed sampling bin together with the outer sampling area 112, i.e. the sampling bin is closed. The fermented grain sampler is then removed from the pile or pit by lifting the handle 120. After the fermented grain sampler is taken out, the second pipe body 210 is driven to rotate in the first pipe body 110 again, so that the inner sampling area 212 is rotated to the outer sampling area 112, and the sampling bin can be opened again, so that the fermented grain sample can be taken out conveniently.

The unstrained spirits sampler that this application provided, it is after the completion to the sampling of unstrained spirits sample to and before taking out the unstrained spirits sample from the unstrained spirits sampler, the unstrained spirits sample can be in confined sampling storehouse all the time, consequently the unstrained spirits sample is difficult for receiving interference and pollution in the sampling process, can ensure the accuracy and the representativeness of sampling.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples merely represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the utility model. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
