[0051] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] The drum concave plate gap adjustment method provided in the embodiment of the present application can be applied in the application environment shown in FIG1. ​​Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. During the grain harvesting process of the harvester, the computer device obtains the regional image of the harvester corresponding to the threshing area; the grain to be identified is placed in the threshing area; according to the regional image, the grain state and non-grain state of the grain to be identified are determined; the non-grain state includes at least one of the stalk state and the ear state; according to the grain state and non-grain state of the grain to be identified, the gap distance between the concave plate and the drum is adjusted. Among them, the computer device can be both a terminal and a server. The terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. The server 104 may be implemented as an independent server or a server cluster consisting of multiple servers.

[0053] In an exemplary embodiment, as shown in FIG2 , a method for adjusting the gap between a drum and a concave plate is provided, which is described by taking the method applied to the computer device in FIG1 as an example, and includes the following steps 201 to 203. Among them:

[0054] Step 201 : when a harvester is harvesting grains, an area image of a threshing area corresponding to the harvester is obtained.

[0055] Among them, the threshing area is where the grains to be identified are placed. The threshing area also includes a concave plate and a roller. For example, as shown in FIG3, FIG3 is a schematic diagram of the threshing area. FIG3 is a roller in the threshing area. FIG3 is a concave plate in the threshing area. FIG3 is a schematic diagram of ...

[0056] Specifically, when the harvester is harvesting grains, a camera installed in the threshing area obtains an area image of the harvester corresponding to the threshing area.

[0057] Step 202: determining the grain state and non-grain state of the grain to be identified based on the regional image.

[0058] The grain state can be understood as the damage state of the grain, such as whether the grain is intact, peeled, or cracked. The non-grain state includes at least one of the stalk state and the ear state, such as, for example, whether the stalk is cut and the degree of cutting; whether the ear is cut and the degree of cutting, and whether it carries grains.

[0059] One optional implementation method may be to input the regional image into a preset image recognition model, and identify the grain state and non-grain state of the grain to be identified from the image content of the regional image.

[0060] Another optional implementation method may be to classify the area images into grain images and non-grain images based on the image contents of the area images; determine the grain state of the grain to be identified in the threshing area based on the grain images; and determine the non-grain state of the grain to be identified in the threshing area based on the grain type of the grain to be identified and the non-grain images.

[0061] Exemplarily, based on the image content of the regional image, the regional image that only contains grains in the image content is taken as the grain image; the remaining regional image except the grain image is taken as the non-grain image; based on the grain image, the grain state of the grain to be identified in the threshing area is determined; and based on the grain type of the grain to be identified and the non-grain image, the non-grain state of the grain to be identified in the threshing area is determined.

[0062] Specifically, based on the grain type of the grain to be identified and the non-grain image, the non-grain state of the grain to be identified in the threshing area is determined, including: when the grain type of the grain to be identified represents eared grain, identifying the stalk state and ear state of the eared grain in the non-grain image; when the grain type of the grain to be identified represents earless grain, identifying the stalk state of the earless grain in the non-grain image.

[0063] Exemplarily, when the grain type of the grain to be identified is characterized by grains with ears (such as corn, sorghum, etc.), the stalk state and ear state of the grains with ears in the non-grain image are identified; when the grain type of the grain to be identified is characterized by grains without ears (such as barley, wheat, etc.), grains without ears themselves do not have ears, so only the stalk state of the grains without ears in the non-grain image is identified.

[0064] Step 203, adjusting the gap distance between the concave plate and the drum according to the grain state and the non-grain state of the grain to be identified.

[0065] The gap between the concave plate and the drum is determined by the difficulty of threshing the grain. For grains that are difficult to thresh, a smaller gap is used, while for grains that are easy to thresh, a larger gap is used. Adjusting the threshing area helps to maximize the performance of the machine.

[0066] In one of the embodiments, the grain state and the non-grain state of the grains are to be identified, and the adjustment distance to be adjusted between the concave plate and the roller is determined; according to the adjustment distance, the gap distance between the concave plate and the roller is controlled.

[0067] In another embodiment, the rotation direction of the concave plate adjustment rod located on the concave plate is determined according to the grain state and non-grain state of the grain to be identified; the concave plate adjustment rod is controlled to rotate along the rotation direction by a preset angle to adjust the gap distance between the concave plate and the roller.

[0068] The concave plate adjustment rod may be an adjustment rod for controlling the gap distance. For example, as shown in FIG4 , the concave plate adjustment mechanism includes a concave plate adjustment rod and an adjustment intermediate connecting rod. The concave plate adjustment rod is rotated to move the concave plate fixing plate through the two intermediate connecting rods on both sides of the concave plate, so that the distance between the concave plate and the roller increases or decreases.

[0069] For example, as shown in the schematic diagram of the concave plate adjustment motor in FIG5 , the blue part in the figure is the concave plate adjustment motor, and the movement of the concave plate adjustment rod is driven by the motor. The motor can receive electrical signal instructions and can also automatically adjust according to a preset control program.

[0070] Exemplarily, the rotation direction of the concave plate adjustment rod located on the concave plate is determined according to the grain state and non-grain state of the grain to be identified; when the rotation direction is clockwise, the first preset angle is adjusted in the clockwise direction to increase the gap distance between the concave plate and the roller; when the rotation direction is counterclockwise, the second preset angle is adjusted in the counterclockwise direction to decrease the gap distance between the concave plate and the roller.

[0071] In yet another embodiment, the rotation direction and adjustment angle of the concave plate adjustment rod located on the concave plate are determined according to the grain state and non-grain state of the grain to be identified; the concave plate adjustment rod is controlled to rotate along the rotation direction to adjust the gap distance between the concave plate and the drum.

[0072] The above-mentioned roller concave plate gap adjustment method, device, computer equipment and storage medium, when the harvester is harvesting grains, obtains a regional image of the harvester corresponding to the threshing area; the grains to be identified are placed in the threshing area; according to the regional image, the grain state and non-grain state of the grain to be identified are determined; the non-grain state includes at least one of the stalk state and the ear state; according to the grain state and non-grain state of the grain to be identified, the gap distance between the concave plate and the roller is adjusted. This embodiment can adjust the gap distance between the concave plate and the roller according to the grain state and the non-grain state, improve the grain harvesting efficiency while ensuring that the grains are not damaged, and at the same time can avoid the blockage of the roller and reduce the operation time of clearing the blockage delay.

[0073] In one embodiment, the rotation direction of the concave plate adjusting rod located on the concave plate is determined according to the grain state and non-grain state of the grain to be identified, including: when the grain state indicates that the grain is broken, the rotation direction is determined to be clockwise; when the grain state indicates that the grain is normal, the rotation direction of the concave plate adjusting rod located on the concave plate is determined according to the non-grain state.

[0074] Specifically, when the grain state indicates that the grains are broken, it proves that the gap distance between the concave plate and the drum is too small at this time, which affects the completeness of the grain harvesting, so the gap distance between the concave plate and the drum needs to be increased, and the rotation direction is determined to be clockwise; when the grain state indicates that the grains are normal, it proves that adjusting the gap distance between the concave plate and the drum does not affect the completeness of the grain harvesting, so it is necessary to further judge whether the gap distance between the concave plate and the drum affects the harvesting degree of the non-grain part.

[0075] In one embodiment, the rotation direction of the concave plate adjusting rod located on the concave plate is determined according to the non-grain state, including: when the non-grain state indicates that no grains are carried and the cutting is abnormal, the rotation direction is determined to be clockwise; when the ear state indicates that grains are carried and the cutting is normal, the rotation direction is determined to be counterclockwise.

[0076] For example, when the non-grain state indicates that the grains are completely separated from the stems and the cutting is abnormal (such as severe stem cutting), the rotation direction needs to be determined to be clockwise to increase the gap distance between the concave plate and the drum; for eared cereals, when the ear state indicates that the cereals are carried, it proves that the threshing of the eared cereals is not thorough, so the gap distance between the concave plate and the drum needs to be reduced and increased to ensure smooth threshing of the cereals, and therefore, the rotation direction is determined to be counterclockwise.

[0077] In the present embodiment, when the grain state indicates that the grain is broken, the rotation direction is determined to be clockwise; when the grain state indicates that the grain is normal, the rotation direction of the concave plate adjusting rod located on the concave plate is determined according to the non-grain state. The present embodiment can more accurately adjust the rotation direction of the concave plate adjusting rod according to the grain state and the non-grain state, so as to further accurately adjust the gap distance between the concave plate and the roller.

[0078] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0088] In one embodiment, the distance adjustment module 12 is also used to determine the rotation direction as clockwise when the non-grain state indicates that there is no grain and the cutting is abnormal; and to determine the rotation direction as counterclockwise when the ear state indicates that there is grain and the cutting is normal.
