[0002] As a common edible bean, edamame needs to go through a series of primary processing processes after picking, including multiple processing links such as impurity removal, cleaning, air drying and color sorting. Although some stand-alone equipment for these processing links has appeared on the market, in the actual production process, the connection between these stand-alone equipment is not optimized and smooth, which often leads to a low degree of mechanized processing throughout the process, low production efficiency and high labor costs. Specifically, in the screening and impurity removal process of edamame pods, too much reliance on manual operation is relied on, which is inefficient and has great interference from human factors, resulting in unstable screening results. In the cleaning process, edamame pods are mostly cleaned by soaking or spraying. Although this cleaning method is simple and easy, it is difficult to effectively remove impurities such as rotten leaves and branches remaining on the edamame pods, affecting the commercial quality of the edamame pods. In addition, the existing edamame pod primary processing equipment often lacks air drying and color sorting devices, resulting in high surface moisture after the pods are cleaned, and it is difficult to remove the spots and inferior fruits, affecting subsequent storage and sales. Therefore, it is very necessary to develop a post-harvest primary processing device for edamame pods that integrates equipment such as impurity removal, cleaning, air drying, and color sorting. In the process of equipment matching, the quantity ratio and process sequence of each device should be reasonably configured to ensure the rational use of the equipment and improve production efficiency.

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the present invention is not limited to the following embodiments.

[0021] Embodiment 1:

[0022] See attached Figure 1A post-harvest cleaning and screening device for edamame pods comprises a control device, an air selection device, a cleaning device, an air drying device and a color selection device; the control device is electrically connected to the air selection device, the color selection device, the cleaning device and the air drying device respectively; the air selection device, the cleaning device, the air drying device and the color selection device are sequentially connected via a conveying device, and the edamame pods are sequentially passed through the air selection device via the conveying device for preliminary impurity removal, the cleaning device for thorough impurity removal, the air drying device for surface air drying, and finally the color selection device for removing unqualified edamame pods, thereby completing the primary processing of impurity removal, cleaning, air drying and screening of the edamame pods. It can be known from the above structure that the edamame pods first enter through the feeding port of the air selection device, and the preliminary impurity removal of the edamame pods is completed in the air selection device, mainly to remove some dust on the edamame pods, so as to avoid the dust attached to the edamame pods from affecting the judgment of the color selection device during subsequent color sorting. The edamame pods that have undergone preliminary dust removal are sent to the cleaning device via the conveying device, and the edamame pods are cleaned in many aspects by the roller 8 and multiple groups of stirring brushes 10 in the cleaning device to ensure thorough cleaning, and then further impurities are removed again by spraying and soaking cleaning methods. The cleaned edamame pods basically meet the standards, and then the edamame pods are further dried by the air drying device, and multiple groups of industrial fans 12 are set to dry the edamame pods, and the industrial fans 12 are further controlled by the control device. The rotation speed makes the moisture on the surface of the edamame pod evaporate quickly, achieving the effect of rapid drying. Finally, it is sent to the color sorting device through the conveying device. The color sorting device is equipped with a camera mechanism for detecting the appearance of the edamame pod and a driving mechanism for screening out the edamame pods that do not meet the standards. The appearance of the edamame pods is obtained by the camera device, and judged by the image processing system of the control device, and then the driving mechanism is controlled to screen out the unqualified edamame pods. The unqualified edamame pods are further used as animal feed or other purposes. The edamame pods screened by the color sorting mechanism basically meet the requirements in appearance. The edamame pods are dusted, cleaned, dried and color sorted in turn by the above devices to complete the production of the assembly line, further improving the production efficiency and reducing the instability caused by manual operation. If necessary, the manual selection link can be further added after the cleaning is completed to ensure the screening effect of the edamame pods.

[0023] Embodiment 2:

[0024] See attached Figure 1. On the basis of the first embodiment, the air separation device includes a plurality of air separators 1; the feed port and the discharge port of two adjacent air separators 1 are butt-jointed. It can be seen from the above structure that the air separation device is used for the preliminary dust removal of the edamame pods, and preferably a three-stage air separator 1 is used. The dust and impurities of the edamame pods are removed in turn by the three air separators 1. The edamame pods are transported to the feed port by the conveyor belt 14 of the air separator 1. After the impurities are removed, they are directly transported to the conveyor belt 14 of the next air separator 1 and transported to the feed port to complete the secondary impurity removal until the third air separation is completed. At this time, the dust and impurities on the edamame pods are basically removed. After the third air separation is completed, it can be further checked whether it is appropriate. The number of air separators 1 can be appropriately adjusted as needed to better complete the preliminary dust removal of the edamame pods. The edamame pods that have undergone preliminary dust removal are further transported to the cleaning device through the discharge port.

[0025] The cleaning device includes a first cleaning box; the first cleaning box includes a drum 8, a stirring shaft 9 and a plurality of stirring brushes 10; the stirring shaft 9 is arranged in the drum 8; and the plurality of stirring brushes 10 are evenly arranged on the stirring shaft 9. As can be seen from the above structure, the first cleaning box includes a drum 8, a stirring shaft 9 is arranged in the center of the drum 8, and a plurality of stirring brushes 10 are evenly arranged on the stirring shaft 9. The rotation of the drum 8 itself, the friction and impact force on its surface, can remove the dirt and impurities on the surface of the edamame pods, and the stirring shaft 9 will also rotate by itself, and the stirring brushes 10 on the stirring shaft 9 will rotate with the stirring shaft 9 to further clean the edamame pods, and clean the edamame pods in all directions and at multiple angles, further enhancing the cleaning effect of the edamame pods, and at the same time, the rotation speed of the drum 8 and the stirring shaft 9 can be controlled to avoid mechanical damage to the edamame pods and protect the appearance quality of the edamame pods. At the same time, the stirring brushes 10 on the stirring shaft 9 can be detachably connected, and the number of stirring brushes 10 can be specifically set according to needs to ensure that the edamame pods are thoroughly cleaned.

[0026] Embodiment three:

[0027] See attached Figure 1 . Based on the second embodiment, the stirring shaft 9 rotates in opposite directions to the drum 8. As can be seen from the above structure, the stirring shaft 9 and the drum 8 rotate in opposite directions, which can be achieved through bearings. Both ends of the stirring shaft 9 are connected to the drum 8 through bearings. Rotation in different directions can further increase the contact time between the stirring brush 10 and the edamame pods, ensuring that the edamame pods can be thoroughly cleaned.

[0028] The cleaning device includes a second cleaning box: the second cleaning box includes a plurality of spray pipes; the spray pipes are used to spray and clean the edamame pods. As can be seen from the above structure, the edamame pods after cleaning in the first cleaning box further enter the second cleaning box through the conveying device, the spray pipes in the second cleaning box first spray the edamame pods, and then soak them in the second cleaning box for a certain period of time after spraying, and then transport them to the air drying device through the conveying device.

[0029] The air drying device includes a plurality of industrial fans 12; the plurality of industrial fans 12 are evenly arranged along the direction of the conveying device, and the direction of the air outlet of each industrial fan 12 is set at a certain angle to the horizontal plane. The washed edamame pods are air-dried by the industrial fans 12, which can quickly evaporate the moisture on the surface of the edamame pods and make them dry. A plurality of industrial fans 12 are set and evenly arranged on the conveying device. The air outlet of each industrial fan 12 is at a certain angle to the horizontal direction, preferably at 45 degrees, and the air outlet is directed toward the conveying device. The air outlets of each industrial fan 12 are directed in different directions, from the middle position to two squares respectively. Preferably, the air outlet of the industrial fan 12 on the left is directed to the right, and the air outlet of the industrial fan 12 on the right is directed to the left, which is more conducive to the air drying of the edamame pods, and also avoids the damage to the outer skin of the edamame pods caused by the vertical air outlet.

[0030] Embodiment 4:

[0031] See attached Figure 1 . On the basis of the third embodiment, the color sorting device includes a color sorting bin 4, an impurity bin 5 and a camera 6 electrically connected to the control device; the color sorting bin 4 is provided with an air jet valve 7 electrically connected to the control device. As can be seen from the above structure, the color sorting device includes a color sorting bin 4, a camera 6 is provided above the color sorting bin 4, and an air jet valve 7 is provided on the other side of the color sorting bin 4. The appearance information of the edamame pods is obtained through the camera 6 and transmitted to the control device. The control device includes an image processing system that cooperates with the color sorting device. Its pre-set algorithm can analyze and process the appearance information of the edamame pods transmitted by the camera 6, and identify the edamame pods that do not meet the color, shape or size, and then control the air jet valve 7 to spray the edamame pods that do not meet the requirements and blow them into the impurity bin 5 below the color sorting bin 4. A plurality of air jet valves 7 are provided to avoid missing the edamame pods that do not meet the requirements. The edamame pods in the impurity bin 5 can be further used as animal and plant nutrients.

[0032] The output end of the color sorting device is provided with a transfer trolley 13. As can be seen from the above structure, the processed edamame pods directly enter the transfer trolley 13 through the output end of the color sorting device for transfer, which is fast and convenient, and avoids accumulation at the output end of the color sorting device.

[0033] The conveying device includes a conveying motor and a conveyor belt 14; the conveying motor drives the conveyor belt 14 to operate; and the conveying motor is electrically connected to the control device. As can be seen from the above structure, the arrangement of the conveyor belt 14 can realize the automatic transportation of edamame pods. The edamame pods coming out of the discharge port of the air selection device are directly transported to the cleaning device and the air drying device by the conveyor belt 14. The edamame pods coming out of the air drying device are also transported to the color selection device through the conveyor belt 14 to complete the screening.

[0034] The control device includes an image processing system and a PLC control system to control the coordinated operation of each device. As can be seen from the above structure, the coordinated operation of each device can be achieved through the PLC control system, which controls the transportation of the conveyor belt 14, the jet of the jet valve 7, the rotation of the drum 8 and the stirring shaft 9, the water spray of the spray pipe, and the wind speed of the industrial fan 12 to complete the automatic cleaning, air drying and screening of the edamame pods, thereby improving the production efficiency and further increasing the yield rate of the edamame pods. When the control device controls the conveying motor, it is necessary to preset the interval time and maintain a certain residence time to ensure the cleaning time of the edamame pods in the drum 8 and the soaking time in the second cleaning box, so as to fully complete the cleaning of the edamame pods.
