Image scanning device and method for rapid detection of imperfect grains

Abstract

The present invention relates to the technical field of grain detection, and specifically discloses an image scanning device and method for rapid detection of imperfect grain grains. During the transmission of the conveyor belt, a second motor is used to drive a vibration block to rotate. Since the vibration block is elliptical, it will not hit the transmission belt when the elliptical block is horizontal, but it can hit the conveyor belt when the elliptical block is longitudinal, causing the conveyor belt to vibrate. Since a transmission pulley and a transmission belt are meshed with each other for transmission, the conveyor belt can be assisted to vibrate. Since the conveyor belt is in a vibrating state, the conveyor belt can be caused to shake the grain grains. When the grain grains are in a shaking state, the scanner can be used to perform a comprehensive scan and detection of the outer surface circumference and the interior, thereby improving the overall scanning accuracy of the device.

Description

Technical Field

[0001] The present invention relates to the technical field of grain detection, and in particular to an image scanning device and method for rapid detection of imperfect grains. Background Art

[0002] Grain imperfect kernel detection image scanning is a method of detecting the presence of imperfect kernels in grains by using image scanning technology. This technology can identify possible imperfect kernels by scanning the surface and internal structure of the grain, such as insect-damaged kernels, diseased kernels, heat-damaged kernels, broken kernels, sprouted kernels, moldy kernels, and mildewed kernels.

[0003] Image scanning technology has shown great advantages, especially for imperfect kernels that are usually difficult to identify from appearance alone and can only be identified by dissecting kernels, such as diseased kernels and heat-damaged kernels. Through this method, grain processing and trading companies can promptly detect and deal with imperfect kernels to ensure grain quality and safety. At the same time, because there is no human factor, this technology can also greatly improve the efficiency and accuracy of grain testing, providing strong support for the development of the grain industry.

[0004] Most existing detection methods use acquisition equipment to take photos of the surface of imperfect grains to collect images, process the collected images, and then use relevant algorithms to analyze them. However, the existing machine vision system uses cameras to take photos of the surface of grains. The entire equipment is large in size and can only perform intermittent photo detection operations on single grains. The overall operation efficiency is not high. A bigger defect is that they can only take images of the surface of the grains, and the internal conditions cannot be known. Therefore, it is very easy to misjudge indicators involving internal judgments such as diseased grains and heat-damaged grains.

[0005] The Chinese patent with the publication number "CN218546552U" discloses a device for detecting imperfect grains of grains, which includes a single grain feeding mechanism, a scanner, an image display terminal and a two-dimensional moving mechanism. A mounting frame connected to the two-dimensional moving mechanism is provided above the two-dimensional moving mechanism. One end of the scanner is hinged at the upper end of the mounting frame, and the other end is connected to the mounting frame through an angle adjustment device. The upper part of the scanner has a scanning window flush with its upper surface. The angle adjustment device is used to drive the other end of the scanner to flip up and down until the scanning window is horizontal or tilted. The scanner is electrically connected to the image display terminal. The single grain feeding mechanism is arranged outside one end of the scanner, and a rotating mechanism is installed at its lower end. The rotating mechanism is used to drive the single grain feeding mechanism to rotate horizontally until its feeding end is located above or to the side of the scanning window. Advantages: It can continuously sort and scan sorghum grains, and improve the detection efficiency of imperfect sorghum grains.

[0006] The above-mentioned device adopts a falling method for scanning during use. However, due to the fast falling speed during scanning, the shooting and scanning time is short. At the same time, each particle can only be scanned once, which may result in incomplete scanning. The particles cannot be fully scanned during the overall detection. The particles are obviously far away from the scanner during the falling period and cannot be scanned by the image scanning. It can be seen that the overall detection accuracy of the existing equipment during detection is poor, so it needs to be improved. Summary of the invention

A driving shaft is fixedly installed on a side of the transmission pulley close to the fixed platform, and the outer end of the driving shaft passes through the fixed platform and extends to the inner side of the fixed platform. Vibration blocks are fixedly installed on the outer surface of the driving shaft located on the inner side of the fixed platform at equal intervals, and the vibration blocks are arranged on the inner side of the conveyor belt. The vibration component is arranged so that during use of the device, the transmission pulley can be driven to rotate by starting the second motor, and the transmission can be driven by the transmission pulley and the transmission belt, thereby driving the three groups of drive shafts to rotate. By rotating the three groups of drive shafts, the vibration block can be auxiliary driven to shake, and the conveyor belt can be vibrated by the rotation of the vibration block, so that the conveyor belt can be evenly transported. Grains, the detection accuracy of the device can be improved.

[0011] Furthermore, the overall shape of the vibration block is set to be an ellipse, and the external corners of the fixed platform are provided with arc-shaped corners.

The drive belt and the inner side of the guide wheel are fitted together. The guide wheel can be used to assist in guiding the drive belt during use, so that the drive belt can fit the drive belt more stably, thereby improving the overall rotation stability of the drive shaft of the device.

[0013] Furthermore, the adjustment component includes a side rail, which is fixedly installed on an upper end of one side of the fixed platform, and a third motor is fixedly installed on one side of the side rail.

[0015] Furthermore, a connecting rod is fixedly installed on the outer end of the side rod on the outer surface of the sliding block close to the discharge mechanism, and the side shape of the connecting rod is set to be L-shaped. A scraper plate is fixedly installed on the outer end of the connecting rod, and strip grooves are evenly spaced at the lower end of the scraper plate. The scraper plate at the outer end of the connecting rod can drive the movement of the strip groove by sliding the sliding block. The movement of the scraper plate and the strip groove at the bottom thereof can assist in sweeping the grain, promote the flattening of the grain, and improve the overall detection accuracy of the equipment.

[0016] Furthermore, the discharge mechanism includes a disc seat, which is fixedly mounted on the top of the turntable, a hopper is fixedly mounted on the top of the disc seat, a discharge frame is fixedly mounted on one side of the hopper, an inner end of the discharge frame is connected to the inner bottom of the hopper, and a discharge assembly is provided at the end of the hopper away from the hopper, and the inner bottom of the hopper is inclined on the side close to the discharge frame. The discharge mechanism is provided so that during use of the equipment, the material inside the hopper can be evenly discharged downward by starting the discharge assembly, and the inclined setting inside the hopper can assist in guiding, so that the material is discharged more evenly, thereby improving the uniformity of discharge.

[0017] Furthermore, the unloading component includes a fifth motor, and the fifth motor is fixedly installed on one side of the discharge frame. The output end of the fifth motor passes through the discharge frame and is fixedly installed with a horizontal axis. The horizontal axis is rotatably connected to the inner side of the discharge frame. Unloading plates are fixedly installed at equal intervals on the outer surface of the horizontal axis. The outer side of the unloading plate and the inner wall of the discharge frame are fitted and connected. The unloading component is arranged so that during use of the device, the fifth motor can be started to drive the horizontal axis to drive the unloading plate to rotate. The rotation of the unloading plate can be used to move the grains inside the discharge frame, so that the grains are evenly discharged from the inner side of the discharge frame, which can improve the grain detection accuracy and efficiency of the device.

[0018] In a second aspect, the present invention provides a method for using an image scanning device for rapid detection of imperfect grains in grains, comprising the following steps:

[0019] Step 1: First move the device to the location where it needs to be tested, then turn on the power of the device, inspect and debug the device parameters to ensure the device status;

[0020] Step 2: Add the sample of imperfect grains to be tested into the inner side of the discharge mechanism, and start the feeding component and transmission mechanism of the discharge mechanism to transport the grains;

[0021] Step 3: Start the detection mechanism, use the fourth motor to drive the scanner to reciprocate, and use the scanner to scan the imperfect grain sample to obtain the image of the imperfect grain;

[0022] Step 4: Analyze the acquired imperfect grain images to determine the quality of the grain;

[0023] Step 5: Process the tested grain according to the judgment results.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] Firstly, in the present invention, by starting the fifth motor to drive the horizontal axis to drive the unloading plate to rotate, the material inside the hopper is caused to slowly fall to the top of the conveyor belt as the unloading plate rotates, and the grains can be conveyed by the rotation of the conveyor belt. Since the fixed table and the conveyor belt are arranged in three groups, the discharge mechanism is used to place the grains on the top of the three groups of conveyor belts for transmission inspection during the inspection process. Compared with the single-group design of the existing equipment, the present equipment adopts multi-group continuous and uninterrupted inspection, and the overall inspection efficiency is faster, and the inspection efficiency is significantly improved.

[0026] Secondly, in the present invention, during the transmission of the conveyor belt, the second motor is used to drive the vibration block to rotate. Since the vibration block is elliptical, it will not hit the transmission belt when the elliptical block is horizontal, but it can hit the conveyor belt when it is longitudinal, causing the conveyor belt to vibrate. Since the transmission pulley and the transmission belt are engaged with each other, the conveyor belt can be assisted to vibrate. Since the conveyor belt is in a vibrating state, the conveyor belt can be caused to shake the grains. When the grains are in a shaking state, the scanner can be used to perform a comprehensive scan and detection of the outer surface circumference, thereby improving the overall scanning accuracy of the device.

[0027] Thirdly, in the present invention, the third motor and the fourth motor are used to drive the scanner to move back and forth in the horizontal and vertical directions. The horizontal reciprocating movement of the scanner can perform multiple cyclic scans on the grains on the outer surface of the conveyor belt. The vibrating design of the conveyor belt can continuously and comprehensively scan the grains, thereby avoiding inaccurate detection, improving detection accuracy, and preventing the back of defective products from being unscanned. During the reciprocating movement of the scanner, the unloading plate and the strip groove can be driven to assist in scraping and breaking up the grains. The vibrating design of the conveyor belt can cause the material to be spread flat on the top of the conveyor belt, thereby avoiding obstruction caused by accumulation of grains, and improving the overall detection accuracy and efficiency of the equipment.

[0048] The present invention provides a method for using an image scanning device for rapid detection of imperfect grains in grains, comprising the following steps:

[0049] Step 1: First move the device to the location where it needs to be tested, then turn on the power of the device, inspect and debug the device parameters to ensure the device status;

[0050] Step 2: Add the sample of imperfect grains to be tested into the inner side of the discharge mechanism 9, and start the unloading component 94 of the discharge mechanism 9 and the transmission mechanism 3 to transport the grains;

[0051] Step 3: Start the detection mechanism 5, use the fourth motor 54 to drive the scanner 57 to reciprocate, and use the scanner 57 to scan the imperfect grain sample to obtain the image of the imperfect grain;

[0052] Step 4: Analyze the acquired imperfect grain images to determine the quality of the grain;

[0053] Step 5: Process the tested grain according to the judgment results.

[0054] The working principle of the present invention is: during the use of the device, grain can be added into the interior of the hopper 92, and the fifth motor 941 can be started to operate, and the fifth motor 941 drives the horizontal shaft 942 to rotate, and the rotation of the horizontal shaft 942 can drive the unloading plate 943 to rotate. At this time, the material inside the hopper 92 slowly falls to the top of the conveyor belt 34 as the unloading plate 943 rotates, and the sixth motor 31 drives the conveyor belt 34 to be driven by the rotating shaft 33, and the grain grains can be slowly conveyed by the rotation of the conveyor belt 34. Since the fixed table 2 and the conveyor belt 34 are arranged in three groups, during the detection process, the first motor 7 can be started to drive the turntable 8 to drive the unloading mechanism 9 to rotate, and the unloading mechanism 9 can be used to place grain on the top of the three groups of conveyor belts 34. Compared with the single-group design of the existing equipment, the present equipment adopts multi-group continuous and uninterrupted detection, and the overall detection efficiency is faster and the detection efficiency is significantly improved. When the conveyor belt 34 is used for transmission, the second motor 324 can be started to run, and the second motor 324 can be used to drive the driving shaft 325 to rotate. The rotation of the driving shaft 325 can drive the vibration block 326 to rotate. Since the vibration block 326 is elliptical, it will not knock the transmission belt when the elliptical block is horizontal, and it can knock the conveyor belt 34 when the elliptical block is vertical, so that the conveyor belt 34 vibrates. Since the transmission pulley 322 and the transmission belt 35 are meshed with each other for transmission, the conveyor belt 34 can be assisted to vibrate. Since the conveyor belt 34 is in a vibrating state, it can cause the conveyor The conveyor belt 34 shakes the grains, and the scanner 57 is used to scan the grains. When the grains are in a shaking state, the scanner 57 can be used to perform a comprehensive scan and detection on the circumference of the outer surface, which can improve the overall scanning accuracy of the device. During use, the device can be operated by starting the third motor 42, and the third motor 42 is used to drive the screw rod 43 to rotate. The screw rod 43 can drive the slider 44 to slide on the inner side of the side rail 41. The sliding of the slider 44 can assist in driving the side fixing rod 51 to reciprocate. The movement of the side fixing rod 51 can drive the two sets of scanners 57 to move. At this time, the fourth motor 54 is started to drive the transmission gear 55 to rotate, and the transmission gear 55 cooperates with the transmission rack 511 The meshing transmission can assist in driving the scanner 57 to move back and forth in the horizontal and vertical directions. The horizontal reciprocating movement of the scanner 57 can be used to perform multiple cyclic scans on the grains on the outer surface of the conveyor belt 34. The vibration design of the conveyor belt 34 can continuously perform a comprehensive scan on the grains, which can avoid inaccurate detection, improve detection accuracy, and prevent the back of defective products from not being scanned. At the same time, during the detection period, the scraper plate 59 is set, which can drive the unloading plate 943 to scrape the grains during the reciprocating movement of the scanner 57. At this time, the strip groove 510 is used to assist in scraping and breaking up the grains. The vibration design of the conveyor belt 34 can cause the material to be spread on the top of the conveyor belt 34, which can avoid the obstruction caused by the accumulation of grains.It can improve the overall detection accuracy and efficiency of the equipment.
