Description

Technical Field

[0001] The present application relates to the field of adaptive peeling control of harvesters, and in particular to a method, device and storage medium for adaptive peeling control of harvesters. Background Art

[0002] Corn husking rate is an important indicator to measure the performance quality of corn harvesters. When corn harvesters are operating in the field, due to the different sizes and maturity of corn, incomplete corn husking and grain loss are inevitable.

[0003] Currently, most corn harvesters use manual adjustment of the gap between the pressure wheel and the husking roller to accommodate different corn varieties. However, this method is difficult to operate and has limited adaptability. Alternatively, operators can rely on experience to manually adjust the husking gap before operation or adjust the harvesting speed during operation based on the size and maturity of the corn.

[0004] However, the above prior art has the following disadvantages:

[0005] Manual adjustment is difficult to operate and has poor adaptability;

[0006] If we only focus on ensuring a high stripping rate, we will increase the loss rate and cause dissatisfaction among land managers;

[0007] If the debarking rate is adjusted by reducing or increasing the vehicle speed, the adjustment effect is generally delayed. In addition, due to the differences in crops between plots, the effect is not ideal and the driver has difficulty in operation. Summary of the Invention

Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0056] Figure 1 A flow chart of an adaptive peeling control method for a harvester provided in an embodiment of the present application.

[0057] The present application provides a harvester adaptive peeling control method, the method comprising the steps of:

[0058] S1: Get the actual peeling rate of the harvester;

[0059] In an embodiment of the present application, obtaining the actual peeling rate of the harvester includes the following steps:

[0060] Collecting images of fruit ears;

[0061] The peeling rate is calculated according to the ear image.

[0062] Specifically, an image collector is installed above the grain box for storing grain. The image collector installed above the grain box collects images of the fruit ears in the box, and the peeling rate can be calculated.

[0063] S2: Obtaining the actual loss rate of the harvester;

[0064] In an embodiment of the present application, obtaining the actual loss rate of the harvester includes the steps of:

[0065] The number of collected lost particles;

[0066] The actual loss rate is calculated based on the number of lost particles.

[0067] Specifically, a loss sensor is installed above the loss collection box for storing lost particles. The loss sensor can sense the number of lost particles in the loss collection box and calculate the loss rate based on the number of lost particles.

[0068] S3: Obtaining a preset peeling rate and a preset loss rate of the harvester;

[0069] Specifically, the preset peeling rate and the preset loss rate of the harvester are fixed parameters pre-set in the harvester.

[0070] S4: Determine the corresponding magnitude relationship between the actual peeling rate and the actual loss rate and the preset peeling rate and the preset loss rate respectively;

[0071] Specifically, the vehicle controller automatically controls the three parameters of the peeling roller speed, the pressure wheel speed, and the peeling roller height difference based on the relationship between the actual peeling rate and the preset peeling rate, as well as the relationship between the actual loss rate and the preset loss rate, so that the peeling rate and the loss rate are maintained within a range that is satisfactory to the user.

[0072] S5: Execute the preset adjustment operation according to the judgment result.

[0073] In the embodiment of the present application, performing the preset adjustment operation according to the judgment result includes the steps of:

[0074] When the actual peeling rate is greater than or equal to the preset peeling rate and the actual loss rate is less than or equal to the preset loss rate, the current parameters are maintained for operation.

[0075] like Figure 5Specifically, P is the actual peeling rate, P0 is the preset peeling rate; L is the actual loss rate, L0 is the preset loss rate; Δr1 is the peeling roller speed adjustment difference, Δr2 is the pinch roller speed adjustment difference, ΔH is the peeling roller height adjustment difference, and T1, T2, T3, and T4 are the observation intervals after adjustment. When the actual peeling rate and actual loss rate are both within the target set value range (i.e., P ≥ P0 & L ≤ L0), the peeling roller speed adjustment difference, pinch roller speed adjustment difference, and peeling roller height adjustment difference parameters are not adjusted.

[0076] In the embodiment of the present application, performing the preset adjustment operation according to the judgment result includes the steps of:

[0077] When the actual peeling rate is greater than or equal to the preset peeling rate and the actual loss rate is greater than the preset loss rate, increasing the speed of the pressing wheel for a first preset time;

[0078] Determining whether the actual loss rate reaches the preset loss rate;

[0079] If yes, keep the current operating parameters;

[0080] If not, the speed of the peeling roller is increased for a second preset time.

[0081] like Figure 5 Specifically, when: P≥P0&L>L0, it means that the actual peeling rate is within a reasonable range, but the actual loss rate is too large. In order to reduce the actual loss rate, the speed of the pressure wheel is appropriately increased by Δr2. After T1 time, if L has not reached the target value, the speed of the peeling roller is appropriately increased by Δr1; after T2 time, if the target value is still not reached, the current P and L values ​​are compared and the next cycle is entered until P≥P0&L≤L0 is reached.

[0082] In the embodiment of the present application, performing the preset adjustment operation according to the judgment result includes the steps of:

[0083] When the actual peeling rate is less than the preset peeling rate and the actual loss rate is less than or equal to the preset loss rate, increasing the height difference of the peeling rollers for a third preset time;

[0084] Determining whether the actual loss rate reaches the preset loss rate;

[0085] If yes, keep the current operating parameters;

[0086] If not, the speed of the peeling roller is increased for a fourth preset time.

[0087] like Figure 5Specifically, when: P<P0&L≤L0, it means that the actual loss rate is within a reasonable range and the actual peeling rate is too small. In order to improve the actual peeling rate, the height difference ΔH of the peeling roller is appropriately increased. After T3 time, if P has not reached the target value, the speed of the peeling roller is appropriately increased by Δr1; after T4 time, if the target value is still not reached, compare the current P and L values ​​and enter the next cycle, P≥P0&L≤L0.

[0088] In the embodiment of the present application, performing the preset adjustment operation according to the judgment result includes the steps of:

[0089] When the actual peeling rate is less than the preset peeling rate and the actual loss rate is greater than the preset loss rate, the preset peeling rate and the preset loss rate are reset.

[0090] like Figure 5 Specifically, when: P<P0&L>L0, it means that the set target value exceeds the limit that the equipment itself can achieve, and the target value needs to be reset, that is, the preset peeling rate and the preset loss rate.

[0091] like Figure 2 The present application provides a harvester adaptive peeling control device, comprising:

[0092] The actual peeling rate acquisition module 10 is used to obtain the actual peeling rate of the harvester;

[0093] An actual loss rate acquisition module 20 is used to acquire the actual loss rate of the harvester;

[0094] A preset value acquisition module 30 is used to obtain a preset peeling rate and a preset loss rate of the harvester;

[0095] A size relationship determination module 40 is used to determine the corresponding size relationships between the actual peeling rate and the actual loss rate and the preset peeling rate and the preset loss rate respectively;

[0096] The adjustment operation execution module 50 is configured to execute a preset adjustment operation according to the determination result.
