[0040] The technical solutions of the present application are further illustrated below in combination with the drawings and through specific embodiments.

[0041] The drag suction dredger is an important equipment in dredging engineering, and its main function is to cut and dig the underwater soil through the rake head, and then suck the dug soil into the ship for storage or directly transport it to the designated place, so as to achieve the purpose of widening the channel, deepening the harbor basin, and maintaining the water depth. During the operation, the drag suction dredger controls the rake head to be lowered to the appropriate depth, and relies on the movement of the ship to drive the rake head to move for cutting operation.

[0042] The existing rake head structure (as shown in Figure 1 ), mainly consists of two parts of fixed body 100 and support cover 200, which are hinged through rotating shaft hole 300 and driven by single driving oil cylinder 500 to rotate the support cover 200 as a whole. The rake tooth structure 400 is welded on the support cover 200, when the driving oil cylinder 500 extends and retracts, the support cover 200 drives the rake tooth structure 400 to change the inclination angle synchronously, so as to adjust the cutting posture.

[0043] However, since the rake tooth structure 400 is rigidly connected with the support cover 200, the cutting posture of the rake tooth structure 400 to the ground changes synchronously with the support cover 200, and the independent adjustment of the cutting depth and the cutting angle cannot be realized, so that the space for adjusting the support cover 200 and the fixed rake tooth structure 400 according to the actual construction environment is very limited, and therefore the optimal construction state cannot be realized.

[0044] Therefore, there is an urgent need for an adjustable rake head device and a use method to solve the above technical problems.

[0045] Embodiment one

[0046] The present application provides an adjustable rake head device, which can realize the adjustment of the cutting depth and the cutting angle of the rake head to achieve the best construction state.

[0047] Referring to Figure 2The adjustable harrow head device provided by the embodiment of the present application comprises a main body 1, a movable cover 2, a cutting assembly 3, a first driving member, a second driving member and a control assembly. The movable cover 2 is rotationally connected with the main body 1. The cutting assembly 3 comprises a support beam 31 and cutting tines 32. The support beam 31 is provided with a plurality of cutting tines 32 along the extending direction of the support beam 31. The support beam 31 is rotationally connected with the movable cover 2. The first driving member is used to drive the movable cover 2 to rotate, so as to adjust the cutting depth of the cutting tines 32. The second driving member is used to drive the support beam 31 to rotate, so as to adjust the cutting angle of the cutting tines 32. The control assembly comprises an input module, an operation module and a control module. The input module is used to obtain soil condition parameters. The operation module is capable of generating a target cutting depth and a target cutting angle based on the soil condition parameters. The control module is used to control the first driving member and the second driving member to operate.

[0048] The adjustable harrow head device provided by the present application can, in use, first obtain soil condition parameters through the input module according to the properties of the target dredged soil, and then generate a target cutting depth and a target cutting angle based on the obtained soil condition parameters through the operation module. Subsequently, the first driving member is controlled by the control module to drive the movable cover 2 to rotate, so as to change the relative inclination angle of the whole movable cover 2 with the bottom surface, directly control the vertical cutting amount of the cutting tines 32, and thus realize the accurate adjustment of the cutting depth of the cutting tines 32, until the cutting depth reaches the target cutting depth. In addition, the second driving member is controlled by the control module to drive the support beam 31 to rotate, so as to enable the plurality of cutting tines 32 arranged along the extending direction of the support beam 31 to synchronously change the contact angle with the surface to be cut, and thus independently adjust the attack angle of the cutting tines 32, until the cutting angle of the cutting tines 32 reaches the target cutting angle, so as to reach the optimal construction state.

[0049] The adjustable harrow head device can, through the cooperation of various components, accurately calculate and adjust the cutting depth and the cutting angle of the cutting tines 32 based on the soil density, particle size and mud concentration, etc., through intelligent dynamic coupling, ensure that the optimal cutting effect can be achieved under different soil conditions such as clay, sandy soil or mixed soil, without relying on the experience of the operator, improve the adaptability of the harrow head to different soil conditions, and also ensure that the harrow head is always in an efficient construction state, reduce the problem of low efficiency caused by improper parameter adjustment, and effectively improve the overall efficiency and quality of the dredging operation.

[0050] The specific structure of the adjustable harrow head device will be described below.

[0051] The main body 1 is the basic load-bearing structure of the entire adjustable rake head device, and provides a mounting and support platform for other components. The main body 1 is made of high-strength metal material and has sufficient strength and rigidity to withstand various forces generated during dredging operations, including cutting force, water flow impact force, and the weight of the device itself. The shape and structure design of the main body 1 is determined according to the actual application scenario and the cooperation requirements with other components, and the main body 1 is provided with mounting interfaces and positioning structures to precisely connect and assemble with the movable cover 2, the first driving member, and other components, so as to ensure that the components can stably operate in cooperation during work.

[0052] The two ends of the support beam 31 are respectively fixedly connected with support end plates 34, and the support end plates 34 and the movable cover 2 are rotationally connected through a first rotating shaft 6; and / or, the main body 1 has two oppositely arranged auxiliary end plates 11, and the two ends of the movable cover 2 are rotationally connected with the auxiliary end plates 11 through a second rotating shaft 7. The support end plates 34 and the auxiliary end plates 11 respectively increase the strength and stability of the connection parts of the support beam 31 and the movable cover 2, and the movable cover 2 and the main body 1, so as to avoid loosening or damage of the connection during frequent rotation and bearing of cutting force. The first rotating shaft 6 and the second rotating shaft 7 can provide a low-friction rotating interface for the connected components, so that the support beam 31 and the movable cover 2, and the movable cover 2 and the main body 1 can smoothly rotate around the corresponding axes. For example, the first rotating shaft 6 connects the support end plates 34 and the movable cover 2, so that the support beam 31 can be accurately rotated to the required angle under the action of the second driving member, to meet the accurate adjustment requirements of the cutting angle under different soil conditions; similarly, the second rotating shaft 7 connects the auxiliary end plates 11 of the main body 1 and the movable cover 2, to ensure that the movable cover 2 can be flexibly rotated to accurately change the cutting depth when driven by the first driving member.

[0053] It should be understood that the above-mentioned rotation implementation through the first rotating shaft 6 and the second rotating shaft 7 is only a preferred implementation mode of the rotation connection of the support beam 31 and the movable cover 2, and the movable cover 2 and the main body 1. Based on the same functional implementation requirements, a person skilled in the art can realize the rotation connection effect of the support beam 31 and the movable cover 2, and the movable cover 2 and the main body 1 through different mechanical forms such as joint bearings, slewing bearings, or flexible hinges. Such rotation form replacement schemes based on the equivalent force transmission principle all belong to the equivalent deformation category of the technical scheme of the present application.

[0054] The first driving member is a first adjusting oil cylinder 4. The first adjusting oil cylinder 4 comprises a first main body 41 and a first telescopic rod 42. The first main body 41 is arranged on the main body 1. The first telescopic rod 42 is coaxially arranged with the first main body 41 and can extend and retract along the axis thereof. The telescopic end of the first telescopic rod 42 is connected with the movable cover 2. When it is necessary to adjust the cutting depth, the first telescopic rod 42 of the first adjusting oil cylinder 4 extends and retracts along the axis thereof relative to the first main body 41 under the action of hydraulic pressure. Since the telescopic end of the first telescopic rod 42 is connected with the movable cover 2, the extension and retraction of the first telescopic rod 42 drives the movable cover 2 to rotate around the second rotation shaft 7, thereby changing the inclination angle of the movable cover 2 and realizing the adjustment of the cutting depth.

[0055] The second driving member is a second adjusting oil cylinder 5. The second adjusting oil cylinder 5 comprises a second main body 51 and a second telescopic rod 52. The second telescopic rod 52 is coaxially arranged with the second main body 51 and can extend and retract along the axis thereof. The telescopic end of the second telescopic rod 52 is connected with the support beam 31. When it is necessary to adjust the cutting angle, the second telescopic rod 52 of the second adjusting oil cylinder 5 extends and retracts along the axis thereof relative to the second main body 51 under the action of hydraulic pressure. Since the telescopic end of the second telescopic rod 52 is connected with the support beam 31, the extension and retraction of the second telescopic rod 52 drives the support beam 31 to rotate around the first rotation shaft 6, thereby changing the cutting angle of the cutting rake tooth 32.

[0056] Specifically, the second main body 51 is arranged on the movable cover 2, thereby shortening the transmission path between the second driving member and the support beam 31, reducing the energy loss and transmission error that may be caused by the excessively long transmission distance, and improving the response speed and control accuracy of the driving, thereby more accurately adjusting the cutting angle.

[0057] Preferably, the movable cover 2 is fixedly connected with a first spherical hinge seat 21, and the telescopic end of the first telescopic rod 42 is hingedly connected with the first spherical hinge seat 21. The support beam 31 is fixedly connected with a second spherical hinge seat 33, and the telescopic end of the second telescopic rod 52 is hingedly connected with the second spherical hinge seat 33. The spherical hinge seat allows the internal hinged part to rotate at a certain angle in multiple directions, thereby enhancing the connection flexibility. In the complex stress environment of the dredging operation, when the movable cover 2 or the support beam 31 produces unexpected angle changes, twists or deviations due to uneven soil stress, the connection angle can be self-adaptively adjusted through the first spherical hinge seat 21 or the second spherical hinge seat 33, thereby avoiding structural damage or jamming caused by rigid connection. At the same time, the spherical hinge seat helps to disperse stress, so that the force transmitted by the telescopic rod is more evenly distributed, thereby prolonging the service life of the connecting components.

[0058] It should be understood that the above-mentioned adjustment mode of the first adjusting oil cylinder 4 and the second adjusting oil cylinder 5 is only an exemplary embodiment, and those skilled in the art can select other equivalent driving forms according to the actual working condition requirements. For example, the first driving member can adopt an electric push rod cooperating with a gear and rack mechanism, the gear is driven to rotate by the motor, and the rack is driven to move linearly, thereby driving the movable cover 2 to rotate around the hinge shaft; the second driving member can also be replaced by a worm gear transmission mechanism, the rotational motion of the worm input shaft is converted into the angular displacement output of the worm gear and the supporting beam 31, thereby realizing the accurate adjustment of the cutting angle. In addition, the driving schemes such as the combination of the pneumatic actuator and the lever arm, the linear motor cooperating with the crank slider mechanism, etc. can also realize the independent rotation control of the movable cover 2 and the supporting beam 31. Although the above-mentioned alternative schemes differ in power source or transmission form, their essence is to independently control the motion output of the two groups of execution mechanisms to realize the decoupled adjustment of the inclination angle of the movable cover 2 and the angle of the supporting beam 31, respectively, so they all belong to the equivalent replacement category of the technical concept of the present application.

[0059] The first driving member is provided with at least two, and a plurality of first driving members are arranged at intervals along the extension direction of the movable cover 2; and / or, the second driving member is provided with at least two, and a plurality of second driving members are arranged at intervals along the extension direction of the supporting beam 31. By respectively arranging a plurality of first driving members and second driving members, the movable cover 2 and the supporting beam 31 can be more uniformly stressed during adjustment, preventing the movable cover 2 and the supporting beam 31 from being twisted and deformed due to uneven local stress, and ensuring the accuracy and stability of the cutting depth and angle adjustment. In addition, the plurality of driving members provide a redundant design, when some of the first driving members or the second driving members fail, the remaining driving members can still maintain certain driving and adjusting ability, ensuring the continuous operation of the harrow head device and improving the reliability of the system.

[0060] In the present embodiment, the first driving member and the second driving member are respectively provided with two, in other embodiments, the number can be adaptively adjusted according to the actual working condition, such as setting one, three or four first driving members or second driving members, which will not be repeated here.

[0061] The input module in the control assembly is used to obtain the soil condition parameters. Specifically, the control assembly further comprises a detector capable of being inserted into the soil to be measured, detecting and generating the soil condition parameters of the soil to be measured, and transmitting the soil condition parameters to the input module. The soil condition parameters include soil compaction, humidity, and ingredient composition.

[0062] Specifically, the detector includes a pressure sensor, a humidity sensor, and a component analysis sensor. The pressure sensor can measure the compactness of the soil to be measured by detecting the reaction force of the soil to be measured on the probe of the pressure sensor and converting it into a corresponding electrical or digital signal, thereby reflecting the hardness of the soil to be measured. The humidity sensor is used to accurately measure the moisture content of the soil. The component analysis sensor determines the composition of the soil, such as clay, sandy soil, or mixed soil, through spectral analysis, chemical detection, and other technical means. The pressure sensor, humidity sensor, and component analysis sensor collect soil condition parameters in all directions and convert them into a signal form that can be recognized and processed by the operation module, providing accurate data basis for subsequent operation and decision-making.

[0063] In addition, the operator is also allowed to manually input the soil layer type and water content in the geological survey report through the human-computer interaction interface, thereby improving the adaptability and versatility of the control assembly.

[0064] The operation module is used to receive the soil condition parameters transmitted by the input module and generate a target cutting depth and a target cutting angle based on the soil condition parameters. The target cutting depth refers to the optimal depth value of the cutting rake tooth 32 tip vertically cutting into the working surface, representing the penetration amount of the cutting rake tooth 32 in the vertical direction. The target cutting angle refers to the optimal angle value formed by the cutting rake tooth 32 blade plane and the tangent direction of the contact point of the working surface, reflecting the mechanical action direction of the cutting rake tooth 32 when cutting into the soil layer. In actual operation, the specific values of the above parameters need to be dynamically adapted according to the real-time geological characteristics, ship speed, and construction targets, which are not limited here.

[0065] The control module is used to control the operation of the first driving member and the second driving member. Specifically, the control module includes a cutting depth unit and a cutting angle unit, both of which are signal connected with the operation module for receiving data from the operation module. The cutting depth unit is connected with the first driving member for controlling the first driving member to drive the movable cover 2 to rotate and monitor the cutting depth in real time. The cutting angle unit is connected with the second driving member for controlling the second driving member to drive the support beam 31 to rotate and monitor the cutting angle in real time.

[0066] Further, the control assembly further comprises a cutting resistance prediction module, which is capable of predicting the cutting resistance faced by the cutting rake 32 when working at the current cutting depth and cutting angle according to the soil condition parameters obtained by the input module. Since different soil conditions have different effects on cutting resistance, the current cutting depth and cutting angle can be determined by accurately predicting the cutting resistance. If the predicted cutting resistance exceeds a reasonable range, it means that the current cutting parameters may not be conducive to efficient operation or may cause excessive wear to the equipment. At this time, the cutting resistance prediction module automatically calculates the cutting depth and cutting angle required to adjust the cutting resistance back to a reasonable range based on its internal algorithm. And pass these new parameter values to the control module, the control module commands the first drive and the second drive to act accordingly, to realize the dynamic adjustment of the cutting depth and angle to adapt to different soil condition parameters.

[0067] Preferably, the control assembly further comprises a display component for displaying the cutting depth and cutting angle. In order to facilitate the operator to intuitively understand whether the cutting depth, cutting angle, etc. meet the expectations, so as to adjust in time. And the display component can be configured with a human-computer interaction interface to facilitate the operator to manually input the adjustment system parameters. Wherein, the display component can be a liquid crystal display, a touch screen display, etc., which will not be described here.

[0068] In addition, the control assembly further comprises an accumulation module, which is used to increase a certain value based on the existing cutting angle and cutting depth. For example, in some special dredging scenarios, when it is necessary to change the cutting depth or cutting angle in a certain area several times to achieve a specific excavation effect. Assuming that the cutting depth adjusted by the operation module and the control module is h1, and the cutting angle is θ1, the operator inputs the cutting depth value Δh and the cutting angle value Δθ required to be increased to the accumulation module through the human-computer interaction interface according to the actual demand. After receiving the instruction, the accumulation module increases the existing cutting depth h1 by Δh to obtain a new cutting depth h2 = h1 + Δh; increases the existing cutting angle θ1 by Δθ to obtain a new cutting angle θ2 = θ1 + Δθ. Then, the accumulation module passes the new cutting depth h2 and the cutting angle θ2 to the control module, and the control module controls the first drive and the second drive to operate again according to the new parameters, drives the movable cover 2 and the support beam 31 to rotate, and adjusts the cutting depth and the cutting angle to the new value to meet the special operation demand.

[0069] It should be noted that the operation module, the control module, the cutting resistance prediction module and the accumulation module involved in the present application are specific implementation principles that can be understood and implemented by those skilled in the art. The core innovation point of the technical scheme of the present application is to realize the technical effect of adjusting the cutting depth and the cutting angle through the cooperation of the specific structure design and the above-mentioned control components, so the conventional technical contents such as the bottom operation details of the operation module, the control module, the cutting resistance prediction module and the accumulation module are not described in detail here.

[0070] Embodiment two

[0071] Figure 3 And Figure 4 Embodiment two is shown, wherein the same or corresponding parts as in embodiment one use corresponding reference numerals as in embodiment one. For the sake of simplicity, only the difference between embodiment two and embodiment one is described. The difference is that, considering that the adjustment range of the inclination angle of the cutting rake teeth 32 is large when working on some soil, the stroke of the second telescopic rod 52 is longer, therefore, the second main body 51 is arranged on the main body 1, so that when facing some soil working scenarios that require a large adjustment range of the cutting angle, since the distance between the main body 1 and the support beam 31 is greater than the distance between the movable cover 2 and the support beam 31, the moving path of the second telescopic rod 52 is increased, and the larger moving path enables the second telescopic rod 52 to have a sufficient stroke to realize a larger angle rotation of the support beam 31, thereby meeting the demand for large-range adjustment of the cutting angle.

[0072] Embodiment three

[0073] The present application also provides a use method of the adjustable rake head device, which is applied to the adjustable rake head device provided in embodiment one, and the specific steps include:

[0074] S1, obtaining soil condition parameters;

[0075] In this step, the detector is inserted into the soil to be measured to detect and generate the soil condition parameters of the soil to be measured, and transmit to the input module, and the operator manually inputs the soil condition parameters through the man-machine interface.

[0076] S2, generating target cutting depth and target cutting angle based on soil condition parameters;

[0077] In this step, the input module transmits the obtained soil condition parameters to the operation module, and the operation module analyzes based on the soil condition parameters through an algorithm, and generates corresponding target cutting depth and target cutting angle according to the actual working condition.

[0078] S3, control the first driving member to drive the movable cover 2 to rotate until the cutting depth reaches the target cutting depth; control the second driving member to drive the support beam 31 to rotate until the cutting angle reaches the target cutting angle.

[0079] In this step, the control module adjusts the hydraulic system to make the first telescopic rod 42 extend or retract along its own axial direction relative to the first main body 41 under the action of the hydraulic pressure. Since the first telescopic rod 42 is connected with the movable cover 2, its extension or retraction drives the movable cover 2 to rotate around the second rotation shaft 7, thereby changing the inclination angle of the movable cover 2 and directly controlling the vertical cutting amount of the cutting rake 32. In this process, the control module continuously monitors the cutting depth and compares it with the target cutting depth. When the cutting depth does not reach the target value, the extension or retraction amount of the first telescopic rod 42 is continuously adjusted until the cutting depth reaches the target cutting depth. Similarly, the control module controls the hydraulic system to make the second telescopic rod 52 extend or retract along its own axial direction relative to the second main body 51 under the action of the hydraulic pressure. Since the second telescopic rod 52 is connected with the support beam 31, its extension or retraction drives the support beam 31 to rotate around the first rotation shaft 6, thereby changing the contact angle of the plurality of cutting rakes 32 arranged along the extension direction of the support beam 31 with the surface to be cut. The control module continuously monitors the cutting angle and compares it with the target cutting angle. When the cutting angle does not reach the target value, the extension or retraction amount of the second telescopic rod 52 is adjusted in time until the cutting angle reaches the target cutting angle, until the best construction state is reached.
