Description

Technical Field

[0001] This utility model relates to the field of grain inspection equipment technology, specifically to an abnormal soybean identification device. Background Technology

[0002] In the statistical identification of imported soybeans, existing technologies mainly employ a manual sampling method. The specific process is as follows: staff use a sampling board to obtain representative samples from the entire batch of soybeans, and then compare the samples one by one with a database of abnormal soybean photos. By identifying problematic soybeans such as moldy, insect-infested, or discolored soybeans in the samples, quality testing and data statistics are completed.

[0003] However, the transparent partitions on the sampling plates of existing technologies have serious durability problems. Long-term and frequent friction with soybean particles causes fine scratches and wear on the surface of the partitions, which reduces the light transmittance of the partitions. This not only affects the accuracy of the inspectors' observation of the color and defects of soybeans, but also makes it difficult to detect some minor abnormalities in time, increasing the risk of missed detection. Utility Model Content

[0004] In view of this, the present invention provides an abnormal soybean identification device to solve the problem that some minor abnormalities in soybeans are difficult to detect in a timely manner, increasing the risk of missed detection.

[0005] In a first aspect, this utility model provides an abnormal soybean identification device, comprising: The shell has an internal cavity and has a first end face and a second end face facing away from each other. The first end face has a plurality of first sieve holes and the second end face has a plurality of second sieve holes. Each first sieve hole and its corresponding second sieve hole are coaxially arranged. The diameter of the first sieve hole is larger than the diameter of the second sieve hole. An observation plate is movably disposed on the first end face and covers or exposes the first sieve holes along its movement path; A lifting cylinder is disposed within the cavity, with its two ends respectively disposed in the first sieve hole and the second sieve hole, and is movable along the axial direction of the first sieve hole or the second sieve hole.

[0006] Beneficial effects: Soybeans to be tested are placed through the first sieve hole, and impurities on the soybeans are removed through the second sieve hole. Then, the observation plate is moved and placed against the first end face, covering the first sieve hole. Observation is carried out through the observation plate. After the observation is completed, the observation plate is removed, and the soybeans placed in the first sieve hole are pushed out by the lifting cylinder for the next batch of soybeans to be screened. This can avoid friction between the soybeans and the observation plate during screening, which would cause scratches and wear on the observation plate. It can improve the accuracy of the inspectors in observing the color and defects of soybeans, detect minor abnormalities in time, and reduce the risk of missed detection.

[0007] In one optional implementation, each of the first sieve holes is coaxially arranged with its corresponding second sieve hole; The aperture of the first sieve hole is larger than the aperture of the second sieve hole.

[0008] Beneficial effects: The first and second sieve holes are coaxially arranged, and the diameter of the first sieve hole is larger than that of the second sieve hole. When soybeans are placed in the first sieve hole, they will get stuck at the connection between the first and second sieve holes (that is, the bottom of the first sieve hole). Shaking the entire device allows the soybeans to vibrate in the first sieve hole, expelling impurities mixed in with the soybeans through the second sieve hole. Furthermore, the coaxial arrangement of the first and second sieve holes greatly ensures the efficiency of impurity removal when the entire device is vibrating, ensuring that the examiners will not have their vision obstructed by impurities when observing soybeans, and further improving the accuracy of the examiners' observation of the color and defects of soybeans.

[0009] In one optional embodiment, a guide groove is provided on the first end face, and the observation plate is slidably disposed on the guide groove.

[0010] Beneficial effects: The observation plate is a transparent plate that is slidably set on the guide groove and slides on the first end face. When soybeans are placed in the first sieve hole, the observation plate slides above the multiple first sieve holes through the guide groove and covers all the multiple first sieve holes.

[0011] In one optional embodiment, the first end face has a comparison area and a soybean screening area, a plurality of first sieve holes are located in the soybean screening area, and an abnormal soybean comparison book is provided in the comparison area.

[0012] Beneficial effects: The comparison area is used to set up an abnormal soybean comparison booklet, which displays pictures and descriptions of different types of abnormal soybeans such as mold, insect infestation, and discoloration. Identifiers can observe soybean samples in the first sieve hole through the observation board and compare the soybean samples with the standard images in the abnormal soybean comparison booklet simultaneously.

[0013] In one optional embodiment, a storage slot is further provided in the comparison area, and the abnormal soybean comparison book is rotatably connected to the storage slot.

[0014] Beneficial effect: The storage compartment provides a holding area for the abnormal soybean comparison booklet. Placing the abnormal soybean comparison booklet in the storage compartment makes it convenient for the identification personnel to compare soybean samples with standard images.

[0015] In one optional embodiment, a sliding member capable of moving parallel to the first end face is provided in the cavity. The sliding member has a planar section and an inclined section. The lifting cylinder is sequentially formed with a wide diameter section, a variable diameter section and a narrow diameter section along its axial direction. The variable diameter section is conical. During at least one segment of the sliding member's movement, the inclined section abuts against the variable diameter section and pushes the variable diameter section to move axially along the first sieve hole or the second sieve hole.

[0016] Beneficial effects: The sliding component works in conjunction with the lifting cylinder with a variable diameter section. When the soybean sample needs to be discharged after the identification is completed, the identification personnel push the sliding component to move horizontally, so that the inclined section of the sliding component gradually lifts the variable diameter section of the lifting cylinder, thereby lifting the entire lifting cylinder and orderly pushing the soybean sample out of the first sieve hole. This solves the problem of soybean residue after identification by traditional sampling devices. By replacing manual operation with mechanical transmission, the operational efficiency of the identification process is improved.

[0017] In one optional embodiment, the slider is provided with a plurality of guide grooves, the extension direction of the guide grooves passing sequentially through the planar section and the inclined section, and the groove width of the guide grooves corresponding to the diameter of the narrow diameter section.

[0018] Beneficial effects: Since some soybeans may be overfitted into the first sieve hole after the identification is completed, the sliding component is pushed so that the guide groove passes through the variable diameter section of the lifting cylinder. During this process, the inclined section and the flat section of the sliding component act on the variable diameter section in turn, lifting the lifting cylinder relative to the first sieve hole and moving it upward. Then the upper end of the lifting cylinder pushes the soybeans out of the first sieve hole, realizing the rapid emptying of soybeans.

[0019] In one optional embodiment, a fixing sleeve is coaxially disposed in the first sieve hole, the wide diameter section is slidably disposed in the fixing sleeve, and the diameter of the narrow diameter section corresponds to the second sieve hole.

[0020] Beneficial effects: A fixing sleeve is set in the first sieve hole. After the soybean is inserted into the first sieve hole, the soybean and the fixing sleeve are in direct contact. The fixing sleeve can fix the soybean more stably and make it easier for the testers to observe.

[0021] In one alternative embodiment, a waste discharge port is provided on the side wall of the cavity.

[0022] Beneficial effect: The waste discharge port provides another channel for impurities to be discharged after they have been screened through the first screen hole, thus improving the discharge efficiency of impurities.

[0023] In one optional embodiment, a sliding groove is provided on the side wall of the cavity, the sliding groove is arranged along the moving direction of the slider, a sliding rod is provided on the side of the slider, the sliding rod is embedded in the sliding groove, and a paddle is provided at the end of the sliding rod away from the slider.

[0024] Beneficial effects: The sliding rod and sliding groove provide stable movement guidance for the sliding component during the movement process. The appraiser only needs to push the lever connected to the sliding rod to drive the sliding component to move stably in the sliding groove through the sliding rod. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] In the inspection and quarantine of imported soybeans, the accuracy and reliability of their quality assessment results are directly related to food safety and the country's grain trade interests. Currently, this process heavily relies on the manual observation and judgment of the inspectors. Specifically, after obtaining soybean samples using traditional sampling plates, inspectors need to flatten and observe the samples in an open environment, and compare the samples with standard abnormal soybean patterns based on their personal experience and memory to complete the statistical analysis of items such as mold, insect infestation, and discoloration.

[0030] This traditional working mode, relying on "human eyes and hands," presents two major systemic risks: First, the core observation component of the sampling plate—the transparent partition—is prone to wear and scratches from continuous contact and friction with soybean particles, creating visual interference. This directly introduces systematic observation errors, causing fluctuations in the judgment standards for color and minor defects by different personnel, or even the same personnel, in different identifications. Second, the samples are exposed to the environment throughout the process and rely on manual transfer and cleaning, which is not only inefficient but also poses a risk of cross-contamination and residue, affecting the representativeness of the statistical samples and the repeatability of the data. Therefore, the relevant technology not only has shortcomings in equipment durability but also faces severe challenges in ensuring the objectivity, consistency, and reliability of identification data.

[0031] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0032] See Figures 1 to 2 This embodiment provides an abnormal soybean identification device, which is mainly used to observe, screen and compare soybean samples to identify their quality.

[0033] The device includes a housing, an observation plate 2, and a lifting cylinder 3.

[0034] The shell has a rectangular box-like structure with an internal cavity. It includes an upper shell 11 and a lower shell 12, with the cavity formed by the upper shell 11 and the lower shell 12. The shell has a first end face 13 and a second end face 14 facing away from each other. The first end face 13 has a plurality of first sieve holes 131, and the second end face 14 has a plurality of second sieve holes 141. In this embodiment, the first sieve holes 131 and their corresponding second sieve holes 141 are coaxially arranged, and the aperture of the first sieve holes 131 is larger than the aperture of the second sieve holes 141. This structure allows the soybean sample to be placed in the first sieve holes 131, while smaller impurities can be filtered out through the second sieve holes 141.

[0035] The observation plate 2 is made of a highly transparent material (such as acrylic or tempered glass). A guide groove 132 is provided on the first end face 13, through which the observation plate 2 is slidably disposed on the first end face 13. By sliding, the observation plate 2 can selectively cover or expose a plurality of first sieve holes 131 below it in its movement path.

[0036] The lifting cylinder 3 is disposed in the cavity. The two ends of the lifting cylinder 3 are respectively slidably disposed in the first sieve hole 131 and the second sieve hole 141, and can move up and down along its axial direction (i.e., the axial direction of the first / second sieve hole 141).

[0037] Furthermore, a push rod 10 is fixedly installed on one side of the shell. In the implementation of this embodiment, the push rod 10 is pushed to insert the front end of the shell into the pile of soybeans 1. The upper layer of soybeans 1 presses the soybeans 1 into each aperture of the first sieve hole 131, and each aperture can only accommodate a single soybean 1. After sampling, the observation plate 2 is pushed out to seal the top of the first sieve hole 131. When performing defect detection, the shell can be shaken so that the dirt and other impurities on the surface of the soybeans 1 are discharged from the second sieve hole 141, which can improve the visibility when visually inspecting the soybeans 1.

[0038] The working process of this embodiment is as follows: Sampling and sieving: Place the soybean sample 1 to be tested into each of the first sieve holes 131. Since the aperture of the first sieve hole 131 is larger than that of the second sieve hole 141, the soybean 1 will be stuck at the bottom of the first sieve hole 131. By gently shaking the device, fine impurities (such as mud, sand, and debris) in the soybean 1 can be sieved out through the second sieve hole 141.

[0039] Observation: Slide the observation plate 2 along the guide groove 132 until it completely covers all the first sieve holes 131. At this time, the inspector can clearly observe the color, shape, defects, etc. of the soybean 1 sample in the first sieve holes 131 through the transparent observation plate 2, while the observation plate 2 does not have direct contact with the soybean 1 sample, thus avoiding friction.

[0040] Ejection and Cleaning: After observation, slide the observation plate 2 open to expose the first sieve hole 131. Then, push the lifting cylinder 3 upward, and the upper end of the lifting cylinder 3 will smoothly eject the soybean 1 sample from the first sieve hole 131, completing one identification cycle. After ejection, the lifting cylinder 3 returns to its original position, ready for the next sampling.

[0041] This embodiment achieves frictionless observation through a movable observation plate 2 and frictionless sampling through a lifting cylinder 3, so that the observation plate 2 is only covered during observation and removed when sampling or changing samples, thus fundamentally eliminating the source of friction.

[0042] The first end face 13 is divided into a comparison area 133 and a soybean screening area 134. Multiple first sieve holes 131 are concentrated within the soybean screening area 134. A storage slot 136 is provided within the comparison area 133, and an abnormal soybean comparison booklet 135 is rotatably connected to the storage slot 136 via a rotating shaft. The inner pages of the abnormal soybean comparison booklet 135 are printed with standard images and text descriptions of various abnormal soybeans 1, such as those with mold, insect infestation, and discoloration.

[0043] Furthermore, the abnormal soybean comparison book 135 and the comparison area 133 of the first end face 13 are connected by a positioning shaft 137, that is, the inspector can flip the abnormal soybean comparison book 135 and observe and screen the soybean 1 sample through the observation board 2.

[0044] Working process: When the identification personnel observe the soybean 1 sample in the soybean screening area 134 through the observation board 2, they can simultaneously flip through and view the abnormal soybean comparison book 135 next to it, and compare the sample with the standard image in real time and intuitively, which greatly improves the accuracy and efficiency of identification.

[0045] See Figures 3 to 6 This embodiment also provides a driving mechanism for the lifting cylinder 3.

[0046] A sliding member 4 is provided in the cavity, which can move parallel to the first end face 13. The sliding member 4 has a planar section 41 and an inclined section 42. Correspondingly, the lifting cylinder 3 has a wide diameter section 31, a tapered variable diameter section 32 and a narrow diameter section 33 formed sequentially along its axial direction.

[0047] A sliding groove 7 is formed on the side wall of the cavity, and the sliding groove 7 is arranged along the moving direction of the slider 4. A sliding rod 9 is fixed to the side of the slider 4, and the sliding rod 9 is embedded in the sliding groove 7 and can slide along it. A paddle 8 for easy operation is provided at the end of the sliding rod 9 away from the slider 4.

[0048] Furthermore, the upper housing 11 and the lower housing 12 combine to form a sliding groove 7.

[0049] Furthermore, a fixing sleeve 5 is coaxially embedded in the first screen hole 131, and the wide diameter section 31 of the lifting cylinder 3 is slidably disposed in the fixing sleeve 5. Multiple guide grooves 43 are provided on the sliding member 4. The extension direction of the guide grooves 43 passes sequentially through the flat section 41 and the inclined section 42, and the width of the guide grooves 43 corresponds to the diameter of the narrow diameter section 33 of the lifting cylinder 3, allowing the narrow diameter section 33 to pass through it.

[0050] The working process of this embodiment: When it was necessary to push out soybean 1, the inspectors pointed outwards ( Figure 2 Move the lever 8 (from center to right) to move the sliding rod 9 and the sliding piece 4 together.

[0051] In the initial stage of movement, the inclined section 42 of the sliding member 4 begins to contact the variable diameter section 32 of the lifting cylinder 3. As the sliding member 4 continues to move, the inclined section 42 pushes the variable diameter section 32 upward through the inclined surface, thereby driving the entire lifting cylinder 3 to move upward, so that its upper end extends into the first sieve hole 131 and pushes out the soybean 1.

[0052] If soybean 1 is too tightly stuck in the first sieve hole 131 (interference fit), the lifting cylinder 3 may not be able to eject it immediately. At this time, the sliding member 4 continues to move, and the guide groove 43 on it will move to the position of the variable diameter section 32 of the lifting cylinder 3. Since the width of the guide groove 43 is sufficient for the narrow diameter section 33 to pass through, but not for the variable diameter section 32, the flat section 41 of the sliding member 4 will push the lifting cylinder 3 upward again when passing through the variable diameter section 32, forming a secondary lifting action, ensuring that even if the soybean 1 is stuck, it can be reliably ejected.

[0053] Furthermore, a waste discharge port 6 can be opened on the side wall of the cavity (see...). Figure 3 Impurities removed from the screen can fall directly through the second screen hole 141 or be collected and cleaned through the waste discharge port 6, thus keeping the device clean.

[0054] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
