Description

Technical Field

[0001] The present application relates to the technical field of agricultural intelligent equipment, and in particular, to a cotton bale compacting method, device, electronic device and storage medium based on a baler. Background Art

[0002] Cotton is a major cash crop and textile industry raw material worldwide, playing a crucial role in economic development. As mechanized cotton picking accelerates year by year and cotton-picking areas continue to expand, the problems of traditional, outdated seed cotton harvesting techniques are becoming increasingly apparent.

[0003] Currently, traditional box-type loose cotton pickers harvest natural cotton with a density of approximately 67-72kg / cubic meter. The storage and transportation of the harvested bulk seed cotton is labor-intensive, inefficient, requires a large amount of space, is poorly dustproof and waterproof, and is prone to cotton rot during storage. Bulk cotton transportation also requires specialized stacking equipment and vehicles, making the process cumbersome and inconvenient to move. Baled cotton pickers compact and bale the harvested seed cotton, achieving a compacted density of approximately 200-220kg / cubic meter. This significantly improves storage and transportation efficiency and reduces seed cotton transportation costs. The cotton quality is not affected by weather changes, fires are prevented, and foreign fibers are effectively prevented from mixing. Round bales are easy to move and stack, occupy a small amount of space, and require no special storage and transportation requirements. Their advantages in seed cotton baling are outstanding, and their advanced nature and practicality have been recognized in production practice, making them a key development direction for cotton harvesting.

[0004] Existing domestic baling technology is still immature. The compaction efficiency of domestic cotton baling machinery generally falls below 200kg / cubic meter, far behind that of foreign equipment. This results in insufficient density, serious problems such as blockages during the baling process, poor bale formation, and uneven seed cotton distribution. Blindly pursuing bale weight and inappropriate compaction density can lead to cotton compaction and lint breakage, resulting in even greater economic losses.

[0005] In summary, in response to the above problems faced in the seed cotton baling process, it is very necessary to study a cotton bale compaction method and system based on a baler with good cotton bale forming degree, uniform seed cotton distribution and reasonable compaction density. Summary of the Invention

[0006] On the one hand, the present application provides a cotton bale compacting method based on a baler to solve the technical problems in the prior art of cotton packaging, such as poor bale forming degree, uniformity of seed cotton distribution, and rationality of compaction density.

[0007] The technical solutions adopted in this application are as follows:

[0008] A cotton bale compacting method based on a baler comprises the following steps:

[0009] According to the current cotton core diameter, the electric signal of the rocker arm cylinder of the baler is adjusted to adjust the tension rocker arm pressure value acting on the cotton core in real time to adaptively adjust the cotton core compaction strength;

[0010] If the current cotton core diameter reaches the set baling diameter, the feeding mechanism motor is controlled to stop running and the cotton core baling action is directly performed according to the cotton core compaction strength, and the cotton bale is ejected according to the operation instruction; if the current cotton core diameter is less than the set baling diameter, the feeding mechanism motor is controlled to run and the cotton is fed according to the set cotton feeding speed, and the above steps are repeated during the cotton feeding process.

[0011] Furthermore, before adjusting the electric signal of the rocker arm cylinder of the baler according to the current cotton core diameter to adjust the tensioning rocker arm pressure value acting on the cotton core in real time to adaptively adjust the cotton core compaction strength, the method further includes the following steps:

[0012] After the equipment is started, the rocker cylinder of the baler is automatically controlled to adjust the tension rocker arm to reset downward at a certain pressure.

[0013] Furthermore, after the equipment is started, the rocker cylinder of the baler is automatically controlled to adjust the tension rocker arm to reset downward at a certain pressure, specifically including the following steps:

[0014] When there is no cotton core in the baler, the rocker cylinder of the baler is automatically controlled to adjust the free end of the tensioning rocker arm to a certain pressure and drop it to the calibrated lowest position;

[0015] When there is a cotton core in the baler, the rocker arm oil cylinder of the baler is automatically controlled to adjust the free end of the tensioning rocker arm to a certain pressure and drop it to the compacting position.

[0016] Furthermore, the method of adjusting the electric signal of the rocker cylinder of the baler according to the current cotton core diameter to adjust the tensioning rocker pressure value acting on the cotton core in real time to adaptively adjust the cotton core compaction strength specifically includes the following steps:

[0017] The current working angle of the tensioning rocker arm obtained by the angle sensor is converted to obtain the current cotton core diameter and the pressure area of ​​the cotton core in the baler;

[0018] The target pressure of the rocker arm cylinder is adaptively calculated based on the current working angle of the tensioning rocker arm and the current cotton core diameter:

[0019] P target =P Base α k α θ α V α β

[0020] Among them, P target is the target pressure of the rocker cylinder, P Base is the rocker cylinder base pressure, and:

[0021]

[0022] Among them, S Pack is the pressure area of ​​the cotton core in the baler, S kcylinder P is the pressure acting area in the rocker cylinder, Cotton is the cotton core pressure, according to the required target cotton density ρ set OK, α k is the area influence coefficient, which is determined by the cotton core pressure P Cotton And the pressure acting area S in the rocker cylinder kcylinder Determine; α θ is the angle influence coefficient, which is related to the cotton core pressure area S through the current working angle of the tensioning rocker arm Pack Determine the α V is the speed influence coefficient, which is determined by correlating the current working angle of the tensioning rocker arm with the rate of change of the cotton core diameter. β is the tensioning rocker arm pressure angle influence coefficient, which is used to eliminate the actual influence caused by the angle component. In the process of cotton core enlargement, if the pressure direction of the tensioning rocker arm in the baler is always perpendicular to the center of the cotton core, the tensioning rocker arm pressure angle influence coefficient α β is 1.

[0023] Furthermore, the method of adjusting the electric signal of the rocker cylinder of the baler according to the current cotton core diameter to adjust the tensioning rocker pressure value acting on the cotton core in real time to adaptively adjust the cotton core compaction strength also includes the steps of:

[0024] If the current cotton core diameter is less than or equal to the minimum bale diameter of the baler, the control target pressure of the rocker cylinder is the preset minimum bale reference pressure;

[0025] If the current cotton core diameter differs from the maximum cotton core diameter of the baler by a set value, the tensioning rocker arm pressure value acting on the cotton core is equal to the preset maximum isolation buffer pressure until the current cotton core diameter is consistent with the maximum cotton core diameter of the baler. The maximum isolation buffer pressure is less than or equal to the seed cotton compaction pressure, and the seed cotton compaction pressure is the maximum tensioning rocker arm pressure value corresponding to the baler under the set cotton core compaction density and diameter.

[0026] Furthermore, the method further comprises the steps of:

[0027] Detect the speed difference between the two baling motors of the baler. If the speed difference is greater than the set value, an alarm will be issued to remind you to perform belt maintenance and adjustment.

[0028] Furthermore, the process of controlling the feeding mechanism motor to operate according to the set cotton feeding speed to feed cotton also includes the following steps:

[0029] When detecting that the cotton in the baling machine is full or the feeding action is manually operated, the feeding mechanism motor is controlled to run at a set cotton feeding speed to feed the cotton;

[0030] When detecting that the cotton in the baling machine is empty, the feeding mechanism motor is stopped first, and then the baling motor is stopped from running, until the cotton in the baling machine is detected to be full or the feeding action is manually operated, the feeding mechanism motor is controlled to run at a set cotton feeding speed to feed the cotton.

[0058] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0059] Figure 1 is a schematic diagram of a baler according to the present application, which comprises a front baling box 1, a tensioning rocker arm 2, a rocker arm oil cylinder 3, a belt set 4, a baling roller 5, a baling motor 6, a box oil cylinder 7, and a rear baling box 8. The belt set 4 in the baler is wound around the fixed multiple baling rollers 5 through the tensioning rocker arm 2. The internal winding compaction space of the belt set 4 increases when the tensioning rocker arm 2 floats upward and decreases when the tensioning rocker arm 2 floats downward. The baler is driven by two baling motors 6 to drive the corresponding baling rollers 5 to rotate the belt set 4. The bottom of the baler is provided with a feeding mechanism. The seed cotton is fed into the bottom of the baling mechanism and wound into a shape by the belt set 4. As the feeding continues to increase, the density and diameter of the cotton core increase, thereby overcoming the pressure of the rocker arm oil cylinder 3 to lift the tensioning rocker arm 2.

[0060] The baler also has a rocker arm oil cylinder pressure maintaining valve. When the valve loses power, it can realize the function of maintaining the pressure of the tensioning rocker arm 2 in the power source cut-off state. This can meet the needs of the operator to stop and maintain during the process, and can also ensure that the cotton core fed into the baling mechanism is not loose. Compared with the control system of the traditional equipment, which causes the rocker arm to lose pressure immediately after stopping, the present application can work again after stopping and can still ensure the compactness of the bale, and has better applicability and flexibility.

[0061] Figure 2The control system of the baler of the present invention is schematically illustrated. It includes an angle sensor as the sensing unit for the tensioning rocker arm 2; a pressure sensor as the sensing unit for the rocker arm cylinder 3; a speed sensor as the sensing unit for the baling motor 6; an angle sensor as the opening sensing unit for the front baling box 1; a photoelectric switch and a speed sensor as sensing units for the feeding mechanism at the front end of the box; a vehicle-mounted controller as the system's control unit for data processing and command output; a hydraulic cylinder as the system's actuator, controlling the extension and contraction of the cylinder to achieve the lifting and lowering of the tensioning rocker arm 2 and the opening and closing of the baling box; a hydraulic motor as the system's actuator to control the operation of the belt assembly 4; and a hydraulic motor as the actuator for the feeding mechanism to control seed cotton feeding. An interactive touch screen is used to control the system's compaction force, cotton core diameter, and various parameter display settings.

[0062] The feeding mechanism of the present application includes multiple sets of combing rollers and feeding belts, which have the functions of seed cotton storage, combing and transportation. The actual application is not limited to this form and can be adjusted according to the characteristics of self-propelled and traction machines.

[0063] Before implementing the cotton bale compaction method, the baler and control system can be prepared accordingly, including:

[0064] Before the equipment leaves the factory, the active angle of the tensioning rocker arm is calibrated to limit the opening range of the tensioning rocker arm and determine the minimum and maximum bale diameters of the baler; the tensioning rocker arm 2 moves up and down through the rocker arm cylinder 3, and the downward pressing force of the tensioning rocker arm 2 is adjusted by the solenoid valve, and the rocker arm position and compaction pressure are detected by the angle sensor and pressure sensor.

[0065] Speed ​​sensors are installed on the two baling motors 6 that drive the belt group 4 in the baling machine, and the operating speed of the belt group 4 under cotton feeding and baling operations is calibrated before the equipment leaves the factory; angle sensors are installed at the hinges of the baling box, and the maximum opening angle of the box is calibrated before the equipment leaves the factory.

[0066] A speed sensor is installed at the feeding mechanism at the front end of the baler to calibrate the cotton feeding speed before the equipment leaves the factory; photoelectric switches are installed at the high and low positions of the feeding mechanism to detect the amount of cotton stored in the mechanism.

[0067] The above signals are collected by the controller, and the working parameters of the packaging mechanism are displayed on the interactive display screen. The feeding speed, cotton bale diameter, compaction strength and packaging speed can be set through the display screen.

[0068] Next, the system feeds cotton based on cotton storage detection or manual instructions. It calculates the corresponding cotton core diameter by detecting the rocker arm angle and automatically adjusts the solenoid valve current of rocker arm cylinder 3 based on the corresponding functional relationship, achieving adaptive control of the cotton core compaction force. When the cotton core diameter reaches the set size or a manual baling instruction is issued, the system stops feeding cotton and proceeds to baling the cotton core. After the cotton bale is ejected, the baler housing closes, and the tensioning rocker arm 2 returns to the calibrated origin, repeating the cotton feeding and baling process.

[0069] Reference Figure 3 The preferred embodiment of the present application provides a cotton bale compacting method based on a baler, comprising the steps of:

[0070] S2. Adjust the electric signal of the rocker cylinder 3 of the baler according to the current cotton core diameter to adjust the pressure value of the tensioning rocker 2 acting on the cotton core in real time to adaptively adjust the cotton core pressing strength;

[0071] S3. If the current cotton core diameter reaches the set baling diameter, the feeding mechanism motor is controlled to stop running and the cotton core baling action is directly performed according to the cotton core compaction strength, and the cotton bale is ejected according to the operation instruction; if the current cotton core diameter is less than the set baling diameter, the feeding mechanism motor is controlled to run and the cotton is fed according to the set cotton feeding speed, and the above steps are repeated during the feeding process.

[0072] The cotton bale compaction method based on the baler provided in this embodiment adaptively adjusts the pressure value of the tensioning rocker arm 2 according to the current cotton core diameter during the seed cotton baling process to dynamically adjust the cotton core compaction strength, thereby solving the problems of poor cotton bale formation and uneven surface, significantly improving the baling and compaction level of domestic equipment, achieving reasonable cotton bale density and uniform seed cotton distribution, while not damaging cotton lint and cotton seeds, and greatly improving the safety and convenience of seed cotton storage and transportation; the finished cotton bales produced by this embodiment have a smooth surface, good formation, a cotton bale density greater than 230 kg / cubic meter, and uniform seed cotton distribution, meeting the market demand for multiple transportation and long-term stacked storage.

[0073] like Figure 4 As shown, in a preferred embodiment of the present application, before adjusting the electric signal of the rocker cylinder 3 of the baler according to the current cotton core diameter to real-time control the pressure value of the tensioning rocker 2 acting on the cotton core to adaptively adjust the cotton core pressing strength, the steps are also included:

[0074] S1. After the equipment is started, the rocker arm cylinder 3 of the baler is automatically controlled to adjust the tension rocker arm to reset downward at a certain pressure, thereby making necessary preparations for subsequent baling operations.

[0075] like Figure 5As shown, in a preferred embodiment of the present application, after the equipment is started, the rocker cylinder of the baler is automatically controlled to adjust the tensioning rocker arm to reset downward at a certain pressure, specifically including the steps of:

[0076] S11. When there is no cotton core in the baler, the rocker arm oil cylinder of the baler is automatically controlled to adjust the free end of the tensioning rocker arm to a certain pressure and drop it to the calibrated lowest position;

[0077] S12. When there is a cotton core in the baler, the rocker arm oil cylinder of the baler is automatically controlled to adjust the free end of the tensioning rocker arm to a certain pressure and drop it to the compacting position.

[0078] like Figure 6 As shown, in a preferred embodiment of the present application, the electric signal of the rocker cylinder of the baler is adjusted according to the current cotton core diameter to real-time adjust the tensioning rocker pressure value acting on the cotton core to adaptively adjust the cotton core pressing strength, specifically including the steps of:

[0079] S21. Calculate the current cotton core diameter and the compressed area of ​​the cotton core in the baler based on the current working angle of the tensioning rocker arm obtained by the angle sensor;

[0080] S22. Adaptively calculate the target pressure of the rocker arm cylinder based on the current working angle of the tensioning rocker arm and the current cotton core diameter:

[0081] P target =P Base α k α θ α V α β

[0082] Among them, P target is the target pressure of the rocker cylinder, P Base is the rocker cylinder base pressure, and:

[0083]

[0084] Among them, S Pack is the pressure area of ​​the cotton core in the baler, S kcylinder P is the pressure acting area in the rocker cylinder, Cotton is the cotton core pressure, according to the required target cotton density ρ Set OK, α k is the area influence coefficient, which is determined by the cotton core pressure P Cotton And the pressure acting area S in the rocker cylinder kcylinder Determine; α θ is the angle influence coefficient, which is related to the cotton core pressure area S through the current working angle of the tensioning rocker arm Pack Determine the α Vis the speed influence coefficient, which is determined by the current working angle of the tensioning rocker and the rate of change of the core diameter, α β is the tensioning rocker pressure angle influence coefficient, which is used to eliminate the actual influence caused by the angle component, wherein, in the process of increasing the core, if the pressure direction of the tensioning rocker in the baling machine is always vertical to the center of the core, the tensioning rocker pressure angle influence coefficient α β is 1.

[0085] In this embodiment, the controller reads the current working angle of the tensioning rocker 2, adjusts the electric signal of the adjusting valve of the rocker cylinder 3, controls the pressure of the tensioning rocker 2, and the principle of calculating the target pressure of the rocker cylinder is as follows:

[0086] ①The elastic cotton fibers are evenly distributed on the cotton seeds, and the mechanical change in the compression process is relatively complex, which is shown in the attached Figure 7 In the initial stage of compression, the stress of the cotton seeds increases slowly and approximately linearly to mainly eliminate the gap between the fibers, and when the compression density is less than 150 kg / cubic, the cotton density and the compaction degree approximately linearly; when the compression density is greater than 150 kg / cubic, the main part is the plastic deformation of the cotton fibers under pressure, the viscosity of the internal friction between the objects, and the elastic deformation of the cotton seeds under pressure, and the pressure rises quickly, and the higher the density, the more obvious. By fitting the relationship between the two, the target cotton density ρ Set can be determined to determine the cotton core pressure P Cotton , and then a reference rocker cylinder pressure P Base is set to control the compaction degree of the tensioning rocker, and according to the mechanical formula F=P·S, the following related relationship is easily deduced:

[0087] P Cotton ·S Pack =P Base ·S cylinderk

[0088] Among them, S Pack is the pressure area of the cotton core in the baling mechanism; S kcylinder is the pressure action area in the rocker cylinder, which is a fixed coefficient, and the reference pressure of the rocker cylinder can be simplified as:

[0089]

[0090] Since P Cotton and S cylinderk are constant values, set them as the area influence coefficient α k , and α k can be measured according to the field conditions, then the target pressure P target of the rocker cylinder can be simplified as:

[0091] P target =P Base ·αk ·S Pack

[0092] ②Since in the process of seed cotton feeding, S Pack With the increase of the cotton core diameter, in order to control the cotton core density within a predetermined range, the pressure of the rocker arm oil cylinder 3 increases with the increase of the cotton core diameter. The cotton core diameter is detected by the tensioning rocker arm angle signal in this embodiment. Since the belt set 4 should maintain a certain running gap, a moderate cavity gap should be reserved when the tensioning rocker arm 2 is in the lowest position. The corresponding relationship between the rocker arm angle and the cotton core diameter is shown in the following table: Figure 8 , the angle influence coefficient a Pack is introduced, and the angle influence coefficient a θ is introduced. target The actual data measured in the factory is obtained, and the control target pressure P target of the rocker arm oil cylinder 3 is:

[0093] P Base = P k · a θ

[0094] ③In addition to the above factors, there is a functional relationship between the machine-harvested seed cotton pressure and the compression speed under the same compression density, and the corresponding relationship is shown in the following table: Figure 9 In this embodiment, the feeding speed has been pre-calibrated, and the feeding mechanism has the ability to evenly spread the seed cotton, which can ensure uniform feeding of cotton. Taking the seed cotton feeding amount per unit time as V, the cotton core radius as r, the width as l, and the density proportionality coefficient as k, it can be deduced that:

[0095] V·t = r 2 πl·k

[0096] It is easy to know that as the feeding time t increases, the change rate of the cotton core diameter gradually decreases, that is, the change rate of the rocker arm angle decreases. Since the seed cotton feeding amount is uniform and stable, the change rate of the cotton core diameter can be related to the rocker arm angle, and the speed influence coefficient a V is introduced, and the control target pressure P target of the rocker arm oil cylinder 3 is:

[0097] P target = P Base · a k · a θ · a V

[0098] ④In addition to the above factors, the rocker arm pressure angle influence coefficient a β should also be introduced to compensate for the influence caused by the angle component, and then:

[0099] P target = P Base · a k · aθ α V α β

[0100] In this embodiment, during the process of cotton core enlargement, the pressure direction of the tensioning rocker arm 2 in the baler is always approximately vertical to the center of the cotton core, so the actual influence of the angle component can be ignored, that is, α β =1. Figure 10 It is a schematic diagram of the movement process of the tightening rocker arm 2 from the lowest position to the highest position when the diameter of the cotton core 9 increases from small to large.

[0101] like Figure 11 As shown, in a preferred embodiment of the present application, the method of adjusting the electric signal of the rocker cylinder of the baler according to the current cotton core diameter to adjust the tensioning rocker pressure value acting on the cotton core in real time to adaptively adjust the cotton core compaction strength also includes the steps of:

[0102] S23. If the current cotton core diameter is less than or equal to the minimum bale diameter of the baler, the target pressure of the rocker cylinder is set to the preset minimum bale pressure.

[0103] S24. If the current cotton core diameter differs from the maximum cotton core diameter of the baler by a set value, the tensioning rocker arm pressure value acting on the cotton core is equal to the preset maximum isolation buffer pressure until the current cotton core diameter is consistent with the maximum cotton core diameter of the baler. The said maximum isolation buffer pressure is less than or equal to the seed cotton compaction pressure. The said seed cotton compaction pressure is the maximum tensioning rocker arm pressure value corresponding to the baler under the set cotton core compaction density and diameter.

[0104] This embodiment sets a minimum pressure for lifting the bale, a maximum pressure for isolating and buffering, and a pressure for compacting the seed cotton when adjusting the compaction strength of the cotton core. Among them, setting the minimum pressure for lifting the bale satisfies the need to control the rocker arm with the minimum pressure to squeeze the seed cotton into the cotton core state, and also meets the practical problem of inconsistent setting parameters caused by differences in the oil cylinder models and rocker arm range of motion of different balers, thereby improving the applicability of this application. In addition, the packaging film is affected by seasonal temperature differences and light, and the sealing properties of the film tail deteriorate. There is a problem that the edge stress of high-density cotton bales in low temperature environments will expand the cotton film sealing. However, the stress transmission distance of cotton is limited. Setting the maximum pressure for isolating and buffering will not increase the compaction strength when the cotton bale size is about to reach the set size, thereby reducing the stress on the edge of the cotton bale and protecting the storage safety of the cotton bales. Figure 12This graph shows the relationship between compaction density and cottonseed breakage. At compaction densities greater than 250 kg / m³, the probability of cottonseed breakage increases significantly, and the cotton loses its resilience. Cottonseeds can be processed into a variety of products, including linter, protein concentrate, and cottonseed oil. The refined cotton cake residue can be used as livestock feed, possessing multiple economic benefits. Therefore, this application recommends a compaction density of no more than 250 kg / m³ for seed cotton.

[0105] like Figure 13 As shown, in a preferred embodiment of the present application, the cotton bale compacting method based on the baler further comprises the steps of:

[0106] S4. Detect the speed difference between the two baling motors of the baler. If the speed difference is greater than the set value, an alarm will be issued for the stability of the mechanism operation, and a reminder will be given to perform belt maintenance and adjustment.

[0107] like Figure 14 As shown, in a preferred embodiment of the present application, the process of controlling the feeding mechanism motor to operate according to the set cotton feeding speed to feed cotton further includes the steps of:

[0108] S31, reading the high-position photoelectric switch signal of the feeding mechanism, when detecting that the cotton bin in the baler is full or the feeding action is manually operated, controlling the feeding mechanism motor to operate and feed cotton at the set cotton feeding speed;

[0109] S32, read the low-position photoelectric switch signal of the feeding mechanism. When it is detected that the cotton in the baler is empty, the feeding mechanism motor is stopped first, and then the baling motor is stopped. Until it is detected that the cotton in the baler is full again or the feeding action is manually operated, the feeding mechanism motor is controlled to feed cotton according to the set cotton feeding speed.

[0110] It should be pointed out that the feeding mechanism can be adjusted in a variety of ways, and the method of detecting seed cotton reserves is not limited to photoelectric switches, and can be changed according to the characteristics of the mechanism; and it is not limited to the feeding speed calibration method. If the functional requirements of this application are met, the detection position and type of the above-mentioned sensors can be selected and adjusted according to design needs, or other indirect measurement methods can be used, such as using angle signals to detect the opening and closing posture of the box, or detecting the displacement of the oil cylinder to determine the posture of the box. The CAN communication method can be replaced by communication protocols such as RS232 / 485 and Ethernet Modbus-TCP. The above-mentioned interactive touch screen can meet the applicability requirements of full-process automation and convenience of self-propelled harvester packaging, but for traction-type baling equipment or fixed-position baling workbenches, the hardware can be replaced according to usage requirements.
