Description

Technical Field

[0001] This utility model relates to the field of grain sampling technology, specifically to a food testing and sampling device. Background Technology

[0002] A grain sampler is a tool used to extract samples from grains, specifically for sampling within sections of the grain. The sampler typically consists of two sets of stainless steel tubes. The sampler is inserted into the grain pile, and the inner steel tube is rotated to close the inlet, thus obtaining the grain sample. Chinese patent CN219830410U discloses a food testing sampling device, including a sampling tube, a handle, a lever, and a base. The sampling tube has a tubular structure with a pointed bottom and is equipped with a sampling port and a test tube storage port.

[0003] When using existing grain samplers, because the inlet position is fixed and different grains are piled at different depths, it is difficult to use the same sampler to test grain piles with large differences in sampling depth. It is necessary to replace the sampler with one of the appropriate length to continue testing, which is inconvenient and wasteful to use multiple samplers. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a food testing and sampling device that solves the issue of a fixed feed inlet position in grain samplers, which makes it inconvenient to perform segmented sampling of grain piles at different depths.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a food testing and sampling device, comprising a rear half of an outer sleeve, a front half of an outer sleeve, a sampling cylinder, and a traction rod. The front half of the outer sleeve is hinged to the front side of the rear half of the outer sleeve, and the sampling cylinder is rotatably installed inside the rear half of the outer sleeve. The traction rod is slidably installed inside the rear half of the outer sleeve. The rear half and the front half of the outer sleeve are both provided with grooves to restrict the vertical movement of the sampling cylinder. There are multiple sets of sampling cylinders, which are arranged at equal intervals inside the rear half of the outer sleeve. The inlet of the sampling cylinder is corresponding to the inlet of the front half of the outer sleeve. The traction lever is slidably inserted into the left and right sides of the sampling cylinder.

[0006] The rear half of the outer sleeve includes a first sleeve, a first limiting groove, a first insert and a base. The first limiting groove is provided inside the first sleeve. The first insert is fixedly installed on the surface of the first sleeve and a bolt fastener is provided inside the first insert. The base is fixedly installed on the bottom inner side of the first sleeve. The number of first limiting grooves is multiple, and the multiple sets of first limiting grooves are arranged at equal intervals.

[0007] The rear half of the outer sleeve also includes a first handle, which is fixedly installed on the top of the first sleeve and is hollow.

[0008] The front half of the outer sleeve includes a second sleeve, a second limiting groove, a second insert and a feed groove. The second sleeve is hinged to the front side of the rear half of the outer sleeve. The second limiting groove is opened inside the second sleeve. The second insert is fixedly installed on the surface of the second sleeve. The feed groove is opened on the front side of the second sleeve. The feed groove is corresponding to the feed port of the sampling tube. There are multiple sets of the second limiting groove, and these multiple sets of the second limiting groove are arranged at equal intervals.

[0009] The front half of the outer sleeve also includes a drill bit, and the bottom of the second sleeve is fixedly equipped with a drill bit, which is tapered.

[0010] The sampling cylinder includes a cylinder body, a storage chamber, a limiting plate, and a rotating groove. The cylinder body is rotatably installed between the rear half of the outer sleeve and the front half of the outer sleeve. A storage chamber is provided on the front side of the cylinder body, a limiting plate is fixedly installed on the rear side of the cylinder body, and rotating grooves are provided on the left and right sides of the cylinder body. There are multiple sets of limit plates, which are arranged at equal intervals.

[0011] The traction lever includes a second handle and an auxiliary push rod. The second handle is slidably mounted on the top of the rear half of the outer sleeve, and the auxiliary push rod is fixedly mounted on the bottom of the second handle. The auxiliary push rod is in contact with the inner wall of the rear half and the front half of the outer sleeve, and the auxiliary push rod is correspondingly set with the sampling cylinder.

[0012] The beneficial effects of this utility model are as follows: By flipping the front half of the outer sleeve, the channel space between the rear half and the front half of the outer sleeve is opened. According to the depth of the grain pile to be tested, the sampling position height is set in stages. Each set of sampling tubes is pushed into the rear half of the outer sleeve, and the sampling position is adjusted. This avoids the problem of having to replace the sampler of the corresponding length when testing different grain piles. In addition, if a single set of sampling tubes is damaged, it can be directly replaced without affecting other sampling tubes, avoiding the need to replace the entire sampler and reducing resource waste.

[0015] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0016] Figures 1-8 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-8 The present invention will be further described below.

[0017] A food testing and sampling device includes a rear half 1 of an outer sleeve, a front half 2 of an outer sleeve, a sampling cylinder 3, and a traction rod 4. The front half 2 of the outer sleeve is hinged to the front side of the rear half 1, and the sampling cylinder 3 is rotatably mounted inside the rear half 1. The traction rod 4 is slidably mounted inside the rear half 1 of the outer sleeve. Grooves are provided inside both the rear half 1 and the front half 2 of the outer sleeve to restrict the vertical movement of the sampling cylinder 3. Multiple sets of sampling cylinders 3 are arranged equidistantly inside the rear half 1 of the outer sleeve, with the inlets of the front half 2 and the sampling cylinder 3 corresponding to each other. The traction rod 4 is slidably inserted into the left and right sides of the sampling cylinder 3.

[0018] Specifically, the sampling cylinder 3 is limited by the channel space between the rear half 1 and the front half 2 of the outer sleeve, allowing it to rotate between these two sections for easy sealing after sampling. Grooves inside the rear half 1 and the sampling cylinder 3 further restrict its position, enabling the cylinder to be switched as needed and its segmented sampling position to match the grain pile to be tested. Rotating the traction rod 4 pushes the sampling cylinder 3 to rotate within the channel between the rear half 1 and the front half 2 of the outer sleeve, achieving sealing and protection of the sampling cylinder 3 after food sampling.

[0019] The rear half 1 of the outer sleeve includes a first sleeve 101, a first limiting groove 102, a first insert 103, and a base 104. The first limiting groove 102 is provided inside the first sleeve 101. The first insert 103 is fixedly installed on the surface of the first sleeve 101, and the first insert 103 is provided with bolt fasteners inside. The base 104 is fixedly installed on the bottom inner side of the first sleeve 101. There are multiple sets of first limiting grooves 102, and the multiple sets of first limiting grooves 102 are arranged at equal intervals.

[0020] Specifically, the sampling cylinder 3 can rotate inside the first sleeve 101 through the first limiting groove 102, and the vertical movement of the sampling cylinder 3 is restricted. The first insert 103 and the bolt fastener facilitate the connection and fixation of the rear half 1 of the outer sleeve and the front half 2 of the outer sleeve. The gap between the base 104 and the first sleeve 101 allows the bottom end of the traction rod 4 to rotate stably between the two.

[0021] The rear half 1 of the outer sleeve also includes a first handle 105. The first handle 105 is fixedly installed on the top of the first sleeve 101 and is hollow.

[0022] Specifically, by holding the first handle 105, the traction lever 4 is controlled to rotate inside the rear half 1 and the front half 2 of the outer sleeve.

[0023] The front half 2 of the outer sleeve includes a second sleeve 201, a second limiting groove 202, a second insert 203, and a feed channel 204. The second sleeve 201 is hinged to the front side of the first sleeve 101. The second limiting groove 202 is provided inside the second sleeve 201. The second insert 203 is fixedly installed on the surface of the second sleeve 201, and the second insert 203 is correspondingly arranged with the first insert 103 and the bolt fastener. The feed channel 204 is provided on the front side of the second sleeve 201, and the feed channel 204 is correspondingly arranged with the feed port of the sampling cylinder 3. There are multiple sets of second limiting grooves 202, and the multiple sets of second limiting grooves 202 are arranged at equal intervals.

[0024] Specifically, the front side of the first sleeve 101 is sealed by the second sleeve 201, restricting the sampling cylinder 3 between the rear half 1 and the front half 2 of the outer sleeve. The sampling cylinder 3 can rotate inside the second sleeve 201 by the second limiting groove 202, and the vertical movement of the sampling cylinder 3 is restricted. The rear half 1 and the front half 2 of the outer sleeve are connected and fixed by the second insert 203. The grain can enter the sampling cylinder 3 through the feed channel 204 to complete the sampling.

[0025] The front half 2 of the outer sleeve also includes a drill bit 205. The drill bit 205 is fixedly installed at the bottom of the second sleeve 201. The drill bit 205 is conical. Specifically, the drill bit 205 facilitates the insertion of the device deep into the grain pile for sampling.

[0026] The sampling cylinder 3 includes a cylinder body 301, a storage chamber 302, a limiting plate 303, and a rotating groove 304. The cylinder body 301 is rotatably installed between the first sleeve 101 and the second sleeve 201. The storage chamber 302 is provided on the front side of the cylinder body 301, and the limiting plate 303 is fixedly installed on the rear side of the cylinder body 301. The rotating groove 304 is provided on the left and right sides of the cylinder body 301. There are multiple sets of limiting plates 303, and the multiple sets of limiting plates 303 are arranged at equal intervals.

[0027] Specifically, the grain sample is temporarily stored in the storage chamber 302. The limiting plate 303 enables the cylinder 301 to rotate stably between the rear half 1 and the front half 2 of the outer outer cylinder and limits the height of the sampling cylinder 3. The rotating groove 304 enables the rotation of the traction rod 4 to drive multiple sets of sampling cylinders 3 to rotate stably and synchronously, thereby controlling the closure of the storage chamber 302.

[0028] The traction lever 4 includes a second grip 401 and an auxiliary push rod 402. The second grip 401 is slidably installed inside the first grip 105. The auxiliary push rod 402 is fixedly installed at the bottom of the second grip 401, and the auxiliary push rod 402 is in contact with the inner wall of the first sleeve 101 and the second sleeve 201. The auxiliary push rod 402 is correspondingly set with the sampling cylinder 3.

[0029] Specifically, by holding the second handle 401, the traction rod 4 is controlled to rotate inside the rear half 1 and the front half 2 of the outer sleeve, thereby driving multiple sets of sampling cylinders 3 to rotate synchronously, controlling the opening and closing of the feed inlet at the sampling cylinder 3 before and after sampling, and the auxiliary push rod 402 facilitates the quick assembly and disassembly of the traction rod 4 and the sampling cylinder 3 before and after the sampling cylinder 3 is changed.

[0030] In summary: When staff need to sample and test food, the device is inserted into the grain pile. Holding the first handle 105 and the second handle 401, rotating the second handle 401 causes the auxiliary push rod 402 to rotate the cylinder 301 between the first sleeve 101 and the second sleeve 201. The limiting plate 303 slides from the second limiting groove 202 into the first limiting groove 102, connecting the feed channel 204 to the storage chamber 302, allowing for segmented sampling of the grain pile. After the sample enters the storage chamber 302, the second handle 401 is rotated in the opposite direction, causing the inlet of the storage chamber 302 to rotate towards the inner wall of the first sleeve 101, completing the sealing and protection of the sample. The device is then removed, and the remaining grain between the first sleeve 101 and the second sleeve 201 is emptied. The sample in the sampling cylinder 3 is then recovered, completing the sampling process.

[0031] When sampling subsequent grain piles, if the grain sampling depth differs significantly from the previous one, the bolt fasteners at the first insert 103 and the second insert 203 can be removed, the second sleeve 201 can be flipped open from the front side of the first sleeve 101, the traction rod 4 can be pulled out, and each set of sampling cylinders 3 can be taken out. The position of the sampling cylinder 3 can be adjusted according to the sampling depth of the grain to be tested, so that the cylinder body 301 fits against the inner wall of the first sleeve 101, and the rotating groove 304 fits against the inner wall of the first limiting groove 102. Flip the second sleeve 201 over again to close it. Install the bolts and fasteners to connect and fix the first sleeve 101 and the second sleeve 201. Insert the second handle 401 into the first handle 105. Insert the auxiliary push rod 402 into the rotating groove 304, which is close to the inner wall of the first sleeve 101 and the second sleeve 201, until the bottom end of the auxiliary push rod 402 is located between the base 104 and the first sleeve 101, thus completing the adjustment of the sampling position.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
