Description

Technical Field

[0001] This application relates to the field of edamame processing technology, and in particular to a foreign matter screening device for edamame. Background Technology

[0002] When harvesting edamame, operators can easily introduce impurities such as stones from the soil and metal fragments from worn-out agricultural machinery. Additionally, during packaging, wear and tear on processing equipment or human error can easily contaminate the edamame packaging. Enterprises need to prevent problematic food products from reaching the market; therefore, screening out edamame packaging containing foreign objects is a crucial step in ensuring food quality and safety.

[0003] Currently, edamame packages are typically passed through an X-ray foreign object detection machine. The generated images are then analyzed by a computer. If the edamame package contains foreign objects such as stones or metal, the X-ray foreign object detection machine will sound an alarm. Finally, the edamame package containing the foreign object is manually removed, thus completing the foreign object screening process for the edamame.

[0004] Regarding the aforementioned technologies, the inventors believe that manually sorting out edamame containing foreign objects during packaging is inconvenient. Utility Model Content

[0005] In order to automate the screening of edamame packages containing foreign objects and thus reduce manual workload, this application provides a foreign object screening device for edamame.

[0006] The foreign matter screening device for edamame provided in this application adopts the following technical solution:

[0007] A foreign object screening device for edamame includes a belt conveyor, at least one screening assembly mounted on the belt conveyor and located on the side of the conveyor belt, a platform connected to the belt conveyor and located on the side of the screening assembly, and a detection mechanism. The screening assembly includes a swing arm for screening edamame packages containing foreign objects and a drive component for driving the swing arm to rotate. After being rotated by the drive component, the swing arm has a first station and a second station. When the swing arm is in the first station, it is located above the conveyor belt of the belt conveyor. When the swing arm is in the second station, it is located on the side of the conveyor belt of the belt conveyor. When the detection mechanism detects a foreign object, the swing arm rotates from the second station to the first station. When the edamame package containing foreign objects is conveyed to the belt conveyor and abuts against the swing arm, the swing arm rotates from the first station to the second station.

[0008] By adopting the above technical solution, a screening component is set on the side of the belt conveyor, and a carrying platform is set on the side of the screening component. The screening component includes a swing arm and a driving component that drives the swing arm to rotate. After the swing arm is rotated by the driving component, it has a first working position and a second working position. When the detection mechanism detects foreign objects, the swing arm rotates to the top of the conveyor belt of the belt conveyor. At this time, the swing arm is in the first working position. When the edamame package containing foreign objects is conveyed to the belt conveyor and abuts against the swing arm, the swing arm rotates to the side of the conveyor belt of the belt conveyor, thereby pushing the edamame package containing foreign objects to the carrying platform. At this time, the swing arm is in the second working position. This realizes the automated screening of edamame packages containing foreign objects and reduces the amount of manual labor.

[0009] Optionally, the number of screening components is two, with the two screening components located on both sides of the conveyor belt of the belt conveyor, and each screening component corresponding to one loading platform.

[0010] By adopting the above technical solution, since two screening components are set up and located on both sides of the conveyor belt of the belt conveyor, and each screening component corresponds to a carrying platform, when a metallic foreign object is detected, the screening component can push the edamame package containing the metallic foreign object to one carrying platform, and when a stone foreign object is detected, the screening component can push the edamame package containing the stone foreign object to another carrying platform. This allows edamame packages containing different types of foreign objects to be screened into different carrying platforms, making it easier for operators to process edamame packages containing different types of foreign objects separately.

[0011] Optionally, the swing arm is folded toward the conveyor belt of the belt conveyor to form a positioning flange, and the swing arm forms a positioning groove on the positioning flange. The swing arm includes a fixed part that is rotatably connected to the drive member and an extension part that is slidably installed on the fixed part. The fixed part is provided with a locking member, and the extension part is provided with multiple sets of locking holes that cooperate with the locking member along the length direction.

[0012] By adopting the above technical solution, the specific structure of the swing arm is disclosed. The swing arm includes a positioning flange formed by folding towards the conveyor belt of the belt conveyor, and the swing arm includes a fixed part and an extension part. The extension part can be slidably installed on the fixed part, and multiple sets of locking holes on the extension part can cooperate with the locking parts on the fixed part to lock it, so that the length of the swing arm can be adjusted according to actual needs to adapt to different sizes of edamame packaging and belt conveyors of different lengths, thereby improving the adaptability of the device.

[0013] Optionally, the width of the extension gradually decreases in the direction away from the drive member, and when the swing arm is in the first position, the end of the swing arm away from the drive member abuts against the positioning groove of the other swing arm.

[0014] By adopting the above technical solution, the width of the extension gradually decreases in the direction away from the driving component, so that the swing arm can accurately abut against the positioning groove of the other swing arm at the first station, thereby forming a stable interaction structure. It also effectively avoids equipment failure caused by interference between the swing arms and improves the stability and reliability of the screening process.

[0015] Optionally, the top surface of the platform is provided with a loading groove, and the platform is provided with a feeding groove on the side facing the swing arm.

[0016] By adopting the above technical solution, a loading groove is provided on the top surface of the platform, which can provide a stable placement space for the edamame packages containing foreign objects after screening, preventing them from tipping over or scattering during subsequent processing. A feeding groove is provided on the side of the platform facing the swing arm, making it easier for the swing arm to push the edamame packages containing foreign objects into the platform, reducing the probability of the packages being pushed off the platform.

[0017] Optionally, a plastic basket is arranged in the platform.

[0018] By adopting the above technical solution, plastic baskets are placed on the platform, which reduces the impact of edamame packages containing foreign objects on the platform when they are pushed onto it, thereby reducing the probability of damage to the platform. At the same time, the plastic baskets make it easier for operators to remove edamame packages containing foreign objects, which helps to improve the efficiency of subsequent processing.

[0019] Optionally, the plastic basket is provided with mounting grooves at the four corners of its bottom, and magnetic blocks are placed in the mounting grooves.

[0020] By adopting the above technical solution, since the plastic basket has installation grooves at the four corners of the bottom and magnetic blocks are installed in the installation grooves, the plastic basket can be stably placed on the top of the platform, thereby reducing the probability of the plastic basket being displaced due to impact when the edamame package containing foreign objects is pushed onto the platform, which helps the edamame package containing foreign objects to be pushed into the plastic basket.

[0021] Optionally, the frame of the belt conveyor is provided with a snap-fit ​​groove on the side near the loading platform, and the loading platform is provided with a snap-fit ​​protrusion that mates with the snap-fit ​​groove on the side near the belt conveyor.

[0022] By adopting the above technical solution, the frame of the belt conveyor is equipped with a snap-fit ​​groove, and the platform is equipped with snap-fit ​​protrusions that mate with the snap-fit ​​groove, enabling the platform to be quickly and stably installed on the belt conveyor. This structure simplifies the installation process, improves equipment assembly efficiency, and ensures that the platform remains stable during operation, preventing displacement of the belt conveyor along its length due to vibration or external forces, thereby ensuring the accuracy of foreign object screening.

[0023] Optionally, the belt conveyor has a plunger hole in the inner wall of the snap-fit ​​groove and a ball-head spring plunger is installed in the plunger hole, and the snap-fit ​​protrusion has an annular limiting hole for the ball-head spring plunger to snap into.

[0024] By adopting the above technical solution, the combination of the ball-head spring plunger and the annular limiting hole enables the rapid installation and disassembly of the platform on the belt conveyor, improving the efficiency of equipment maintenance and replacement. Simultaneously, this connection method offers high stability, effectively preventing the platform from loosening or falling off during operation, thus ensuring the smooth progress of the screening process and further enhancing the convenience of installation and the reliability of the connection.

[0025] Optionally, the axis of the plunger hole is parallel to the length direction of the conveyor belt of the belt conveyor, the plunger hole is a through hole structure, and the ball-head spring plunger is threadedly installed in the plunger hole.

[0026] By adopting the above technical solution, the axis of the plunger hole is parallel to the length direction of the conveyor belt of the belt conveyor, which enables the ball spring plunger to limit the platform in the width direction of the conveyor belt, thereby improving the stability of the platform installation. The plunger hole is designed as a through hole structure, and the ball spring plunger is threaded into the plunger hole, which further improves the reliability of the connection and facilitates the installation and disassembly of the ball spring plunger, simplifying the assembly process.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. A foreign object screening device for edamame, comprising a belt conveyor, a screening component, a loading platform and a detection mechanism, wherein the screening component is provided with a swing arm and a drive component for rotating the swing arm, the swing arm having a first station and a second station after being rotated by the drive component, and by switching the swing arm between the first station and the second station, the edamame package containing foreign objects can be automatically separated from the conveyor belt and guided to the loading platform, thereby reducing the amount of manual labor.

[0029] 2. By setting a fixed part and an extension part in the swing arm, the fixed part is provided with a locking hole, and the extension part is provided with a locking part that cooperates with the locking hole. The extension part can be slidably installed on the fixed part, so that the length of the swing arm can be adjusted according to actual needs, adapting to different sizes of edamame packaging and belt conveyors of different lengths, thus improving the adaptability of the device.

[0030] 3. By setting a loading slot at the top of the loading platform and a feeding slot on the side of the loading platform facing the swing arm, the swing arm can push the edamame package containing foreign objects into the loading platform more smoothly, reducing the probability of the edamame package containing foreign objects being pushed out of the loading platform.

[0039] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0040] This application discloses a foreign matter screening device for edamame. (Refer to...) Figure 1The foreign object screening device for edamame includes a belt conveyor 1, a screening assembly 2, a platform 3, and a detection mechanism 4 located on the right side of the belt conveyor 1. The screening assembly 2 is mounted on the belt conveyor 1 and located on the side of the conveyor belt of the belt conveyor 1. The platform 3 is connected to the belt conveyor 1 and located on the side of the screening assembly 2. In this embodiment, there are two screening assemblies 2, located on opposite sides of the conveyor belt of the belt conveyor 1, and each screening assembly 2 corresponds to one platform 3. In this embodiment, the detection mechanism 4 is a conventional X-ray foreign object detection machine.

[0041] refer to Figure 1 and Figure 2 The screening component 2 includes a swing arm 21 and a drive component 22 for rotating the swing arm 21. The drive component 22 is mounted on the frame of the belt conveyor. In this embodiment, the drive component 22 is a cylinder, which is electrically connected to the detection mechanism 4. The swing arm 21 folds towards the conveyor belt of the belt conveyor 1 to form a positioning flange 211. The swing arm 21 forms a positioning groove 212 on the positioning flange 211. The swing arm 21 includes a fixed part 213 rotatably connected to the drive component 22 and an extension part 214 slidably mounted on the fixed part 213. In this embodiment, the extension part 214 includes a first part 215 and a second part 216. The first part 215 can slide and fit into the positioning groove 212 of the fixed part 213. The second part 216 is connected to the first part 215, and the width of the second part 216 gradually decreases in the direction away from the drive component 22. The fixed part 213 is provided with a locking member 217, and the extension part 214 is provided with a locking hole 218 that cooperates with the locking member 217. In this embodiment, the locking member 217 is a bolt, the locking hole 218 is a threaded through hole, and the extension 214 and the fixing part 213 are connected by threads, with ideal connection strength. The extension 214 has multiple sets of threaded through holes along its length, so that the length of the swing arm 21 can be adjusted according to actual needs, adapting to different sizes of edamame packaging and different lengths of belt conveyor 1, thus improving the adaptability of the device.

[0042] refer to Figure 2 and Figure 3After being rotated by the drive unit 22, the swing arm 21 has a first station and a second station. When the swing arm 21 is in the first station, it is located above the conveyor belt of the belt conveyor 1; when the swing arm 21 is in the second station, it is located on the side of the conveyor belt of the belt conveyor 1. When the detection mechanism 4 detects a foreign object, the drive unit 22 drives the swing arm 21 to rotate to the first station, at which point one end of the swing arm 21 abuts against the positioning groove 212 of the other swing arm 21. When the edamame package containing the foreign object is conveyed to the belt conveyor 1 and abuts against the swing arm 21 in the first station, the detection mechanism 4 controls the drive unit 22 to drive the swing arm 21 to rotate to the second station, thereby pushing the edamame package containing the foreign object to the loading platform 3, thus realizing the automated screening of the edamame package containing the foreign object and reducing the amount of manual labor.

[0043] refer to Figure 4 and Figure 5 The frame of the belt conveyor 1 has a locking groove 11 on the side near the platform 3, and a plunger hole 12 is formed in the inner wall of the locking groove 11. A ball-head spring plunger 13 is installed in the plunger hole 12. In this example, the axis of the plunger hole 12 is parallel to the length direction of the conveyor belt of the belt conveyor 1. The plunger hole 12 is a through hole structure, and the ball-head spring plunger 13 is threaded into the plunger hole 12. The platform 3 is provided with a locking protrusion 31 that mates with the locking groove 11, and annular limiting holes 32 are formed on both sides of the locking protrusion 31 for the ball-head spring plunger 13 to engage. The ball-head spring plunger 13 includes a plunger housing 131, a plunger spring 132 installed within the plunger housing 131, and a plunger ball 133 installed within the plunger housing 131. Under the action of the plunger spring 132, the plunger ball 133 always tends to protrude from the plunger housing 131, allowing the plunger ball 133 to engage in the annular limiting hole 32 of the engaging protrusion 31, thereby limiting the stage 3. This helps improve the stability of the stage 3 during operation, avoiding displacement caused by vibration or external force, thus ensuring that the edamame packages containing foreign objects can accurately enter the stage 3.

[0044] refer to Figure 6 and Figure 7 The container has a loading slot 33 on the top and a feeding slot 34 on the side facing the swing arm 21. This makes it easier for the swing arm 21 to push the edamame package containing foreign objects into the container platform 3, reducing the probability of it being pushed out of the container platform 3. A plastic basket 35 is provided in the container platform 3. Each of the four corners of the bottom of the plastic basket 35 has a mounting slot 351 and a magnetic block 352 is provided in the mounting slot 351. In this embodiment, the container platform 3 is made of stainless steel. The magnetic block 352 attracts the container platform 3, so that the plastic basket 35 can be stably arranged in the container platform 3, reducing the probability of the plastic basket 35 shifting. The plastic basket makes it easy for the operator to remove the edamame package containing foreign objects, which helps to improve the efficiency of subsequent processing.

[0045] The implementation principle of the foreign object screening device for edamame according to the embodiment of this application is as follows: When the detection mechanism 4 detects a foreign object, the driving component 22 drives the swing arm 21 to rotate to the first working position. At this time, the swing arm 21 is located above the conveyor belt of the belt conveyor 1. When the edamame package containing foreign objects is conveyed to the belt conveyor 1 and abuts against the swing arm 21 at the first working position, the driving component 22 drives the swing arm 21 to rotate to the second working position. At this time, the swing arm 21 is located on the side of the conveyor belt of the belt conveyor 1, pushing the edamame package containing foreign objects to the loading platform 3, thereby realizing the automated screening of edamame packages containing foreign objects and reducing the amount of manual labor.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
