[0051] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0052] The roller concave plate gap adjustment method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104 or placed on the cloud or other network servers. During the grain harvesting process, the computer device acquires an image of the threshing area corresponding to the harvester; the threshing area contains the grain to be identified; based on the area image, it determines the grain state and non-grain state of the grain to be identified; the non-grain state includes at least one of stalk state and ear state; based on the grain state and non-grain state of the grain to be identified, it adjusts the gap between the concave plate and the roller. The computer device can be either a terminal or a server. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart vehicle devices, etc. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. Server 104 can be implemented using a standalone server or a server cluster composed of multiple servers.
[0053] In one exemplary embodiment, such as Figure 2 As shown, a method for adjusting the gap between the roller concave plates is provided, which can be applied to... Figure 1 The following steps, 201 to 203, are used as an example of computer equipment.
[0054] Step 201: During the grain harvesting process of the combine harvester, acquire the area image of the threshing area corresponding to the combine harvester.
[0055] The threshing area contains the grains to be identified. The threshing area also includes a concave plate and a roller, for example, such as... Figure 3The diagram shows the threshing area. Figure (A) shows the drum in the threshing area, and Figure (B) shows the concave plate in the threshing area. The concave plate is divided into three parts: front, middle, and rear. The grooved bars on the drum are distributed in a spiral pattern around the drum. This forces the grain to pass through the machine in a forward direction, ensuring normal harvesting even under harsh, wet conditions. It should be noted that the harvester utilizes the drum's guide area to achieve threshing and separation functions. The grain enters the moving blades of the drum through the feeder and flows backward into the machine for threshing and separation. The two important components of the threshing and separation section are the drum and the concave plate. The drum threshes the grain, carrying the crop material backward through the machine. The faster the grain is threshed, the easier it is to separate from the material. The concave plate must be able to hold the grain for as long as possible to ensure thorough threshing, and at the same time, it must have sufficient capacity to ensure that the grain is separated into the subsequent cleaning area after threshing.
[0056] Specifically, during the harvesting process, cameras installed in the threshing area capture images of the corresponding threshing area of the harvester.
[0057] Step 202: Determine the grain state and non-grain state of the grain to be identified based on the region image.
[0058] The grain condition can be understood as the state of damage to the grain, such as whether the grain is intact, whether the husk is peeled off, or whether it is cracked. The non-grain condition includes at least one of the stalk condition and the ear condition, for example, whether the stalk has been cut and the extent of the cut; whether the ear has been cut and the extent of the cut, and whether it carries grains, etc.
[0059] One possible implementation is to input the region 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 region image.
[0060] Another possible implementation is to classify the region image into grain images and non-grain images based on the image content of the region image; determine the grain state of the grain to be identified in the threshing region based on the grain images; and determine the non-grain state of the grain to be identified in the threshing region based on the grain type of the grain to be identified and the non-grain images.
[0061] For example, based on the image content of the region image, a region image containing only grains in the image content is designated as a grain image; the remaining region images other than the grain images are designated as non-grain images; the grain state of the grain to be identified in the threshing region is determined based on the grain images; and the non-grain state of the grain to be identified in the threshing region is determined based on the grain type of the grain to be identified and the non-grain images.
[0062] Specifically, based on the grain type and non-grain images of the grain to be identified, 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 a grain with ears, the stalk state and ear state of the grain with ears in the non-grain image are identified; when the grain type of the grain to be identified represents a grain without ears, the stalk state of the grain without ears in the non-grain image is identified.
[0063] For example, when the grain type to be identified represents a grain with ears (such as corn, sorghum, etc.), the stalk and ear state of the grain with ears in the non-grain image are identified; when the grain type to be identified represents a grain without ears (such as barley, wheat, etc.), the grain without ears does not have ears, so only the stalk state of the grain without ears in the non-grain image needs to be identified.
[0064] Step 203: Adjust the gap between the concave plate and the roller according to the state of the grains to be identified and the state of the non-grain grains.
[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 should be used, while for grains that are easy to thresh, a larger gap should be used. Adjusting the threshing zone properly helps to maximize the machine's performance.
[0066] In one embodiment, the state of the grain to be identified (whether it is a grain or not) is used to determine the adjustment distance between the concave plate and the roller; based on 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 adjusting rod on the concave plate is determined according to the grain state and non-grain state of the grain to be identified; the concave plate adjusting rod is controlled to rotate by a preset angle along the rotation direction to adjust the gap distance between the concave plate and the roller.
[0068] The concave plate adjusting rod can be an adjusting rod used to control the adjustment gap distance, for example, such as... Figure 4 The schematic diagram of the concave plate adjustment mechanism shown includes a concave plate adjusting rod and an adjusting intermediate connecting rod. Rotating the concave plate adjusting rod moves the concave plate fixing plate through the two intermediate connecting rods on both sides of the concave plate, thereby increasing or decreasing the distance between the concave plate and the roller.
[0069] For example, such as Figure 5 The diagram shows a concave plate adjusting motor. The blue part in the diagram is the concave plate adjusting motor. The movement of the concave plate adjusting rod is driven by the motor. The motor can receive electrical signal commands or adjust automatically according to a preset control program.
[0070] For example, the rotation direction of the concave plate adjusting rod 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, a 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, a second preset angle is adjusted in the counterclockwise direction to decrease the gap distance between the concave plate and the roller.
[0071] In another embodiment, the rotation direction and adjustment angle of the concave plate adjusting 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 adjusting rod is controlled to rotate along the rotation direction to adjust the angle, so as to adjust the gap distance between the concave plate and the roller.
[0072] The aforementioned method, apparatus, computer equipment, and storage medium for adjusting the gap between the concave plate and the drum involve acquiring an image of the threshing area of the harvester during grain harvesting; placing grain to be identified in the threshing area; determining the grain state and non-grain state of the grain based on the image; the non-grain state including at least one of stalk state and ear state; and adjusting the gap between the concave plate and the drum based on the grain state and non-grain state. This embodiment can adjust the gap between the concave plate and the drum according to the grain state and non-grain state, improving harvesting efficiency while ensuring the grain is not damaged, and simultaneously avoiding drum blockage and reducing operation time delayed by clearing blockages.
[0073] In one embodiment, determining the rotation direction of the concave plate adjusting rod located on the concave plate according to the grain state and non-grain state of the grain to be identified includes: determining the rotation direction as clockwise rotation when the grain state indicates that the grain is broken; and determining the rotation direction of the concave plate adjusting rod located on the concave plate according to the non-grain state when the grain state indicates that the grain is normal.
[0074] Specifically, when the grain condition indicates that the grains are broken, it is shown that the gap between the concave plate and the roller is too small, affecting the integrity of grain harvesting. Therefore, the gap between the concave plate and the roller needs to be increased, and the rotation direction is determined to be clockwise. When the grain condition indicates that the grains are normal, it is shown that adjusting the gap between the concave plate and the roller does not affect the integrity of grain harvesting. Therefore, it is necessary to further determine whether the gap between the concave plate and the roller affects the degree of harvesting of non-grain parts.
[0075] In one embodiment, determining the rotation direction of the concave plate adjusting rod located on the concave plate according to the non-grain state includes: determining the rotation direction to be clockwise when the non-grain state indicates that it does not carry grains and the cutting is abnormal; and determining the rotation direction to be counterclockwise when the ear state indicates that it carries grains and the cutting is normal.
[0076] For example, in the case where the grains are completely separated from the stalks and the cutting is abnormal (e.g., severe stalk cutting), the rotation direction should be determined to be clockwise to increase the gap between the concave plate and the roller. For ear-shaped grains, if the ear-shaped grains are carrying grains, it indicates that the ear-shaped grains are not completely threshed. Therefore, the gap between the concave plate and the roller should be reduced to ensure smooth threshing. Thus, the rotation direction should be determined to be counterclockwise.
[0077] In this embodiment, when the grain condition indicates that the grain is broken, the rotation direction is determined to be clockwise; when the grain condition 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 condition. This embodiment can more accurately adjust the rotation direction of the concave plate adjusting rod according to the grain condition and the non-grain condition, so as to further accurately adjust the gap distance between the concave plate and the roller.
[0078] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.

These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
