Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and particularly to a multi-dimensional profiling cutter bar and a control method thereof. Background Art

[0002] The cutter bar is a core component of agricultural machinery. It is installed on the front side of a tractor and acts on crops to separate the crops from their original growth positions and collect them. For different crops, different harvesting components are required for harvesting, and the harvesting methods and positions of different crops are different. Some crops need to be cut together with the stalks, some crops only need to harvest the fruits, some crops have a lower cutting position, and some crops have a higher cutting position. Therefore, different ways of controlling the movement of the cutter bar are needed. For some crops, the harvesting components need to be in a suspended state for harvesting, and for some crops, the harvesting components need to fully adapt to the undulations of the ground for harvesting.

[0003] In the prior art, the applicant's prior application CN114902874A discloses a harvesting table state switching and adjusting mechanism. In this patent, there are the following disadvantages:

[0004] (1) In this patent, the state switching mechanism includes a slide bar and a slider assembly. The slider assembly can be fixed or slid relative to the slide bar so that the cutter bar can directly switch between the ground profiling mode and the lifting operation mode. In actual use, these two usage modes still cannot meet the rich usage requirements of the cutter bar. For example, in some working conditions, when the cutter bar needs to perform ground profiling movement based on profiling wheels, if a profiling wheel on one side encounters a drainage ditch, it will cause the cutter bar to tilt significantly, affecting the operation of the cutter bar, or causing the cutter bar to bite into the soil and even be damaged. Or in some working conditions, it is necessary to make the cutter bar frame work in a torsional state relative to the tractor. In order to meet various usage requirements of the cutter bar, it is necessary to adjust the structure of the cutter bar to meet more requirements. This is the main technical problem to be solved by the present invention.

[0005] (2) The structure of this patent has the following problems in actual use: The reliability of the structure is relatively low, which is reflected in that when the slider assembly slides relative to the slide bar, it slides smoothly and is easily stuck. The slider assembly and the slide bar are locked by means of tooth-shaped engagement, with a complex structure, high cost, and may easily have problems such as being unable to engage due to jamming. Summary of the Invention

[0006] Object of the Invention: In order to overcome the deficiencies in the prior art, the present invention provides a multi-dimensional profiling cutter bar and a control method thereof that can perform more-dimensional adjustment and meet more usage requirements.

[0007] Technical solution: To achieve the above object, a multi-dimensional profiling cutter platform of the present invention includes a machine frame and a cutter platform frame body. The cutter platform frame body can move with multiple degrees of freedom relative to the machine frame, and a state switching mechanism is connected between the two. The state switching mechanism includes a linear motion actuator and a locking mechanism. Profiling wheels are respectively installed on the left and right sides of the front end of the cutter platform frame body. The state switching mechanism is controlled by a controller to operate.

[0008] Two sets of the state switching mechanisms, namely a left set and a right set, are provided between the machine frame and the cutter platform frame body.

[0009] The machine frame has an intermediate connection seat for connecting the cutter platform frame body and two side connection seats located on the left and right sides of the intermediate connection seat.

[0010] The middle part of the rear side of the cutter platform frame body is connected to the intermediate connection seat through a spherical bearing. The two side connection seats are respectively connected to the cutter platform frame body through tie rods. Both ends of the tie rod are respectively connected to the side connection seat and the cutter platform frame body through spherical bearings.

[0011] Further, the state switching mechanism further includes a connecting rod, and the connecting rod is fixed on the cutter platform frame body.

[0012] The locking mechanism includes a frame arranged around the connecting rod. A roller and a clamping member are installed on the frame. The roller is always in contact with the connecting rod, and the rollers are arranged in pairs. The two rollers in the same pair are respectively arranged on both sides of the connecting rod.

[0013] The two clamping members are respectively arranged on both sides of the connecting rod. The locking mechanism further includes an elastic mechanism. In the locked state, the clamping member is in contact with the connecting rod. In the unlocked state, the elastic mechanism makes a gap between each clamping member and the connecting rod.

[0014] The linear motion actuator is connected to a fixed seat and the frame.

[0015] Further, the cross-section of the connecting rod is square, and the frame is also a square frame. The locking mechanism includes two pairs of rollers, and the two pairs of rollers are respectively arranged at both ends of the clamping member.

[0016] Further, the clamping member is an electromagnet. The clamping member is installed on a mounting plate, and the mounting plate can slide relative to the frame under the action of a guide member. A spring is sleeved on the guide member, and the spring is placed between the two mounting plates corresponding to the two clamping members.

[0017] Further, the frame is composed of two back plates and four vertical plates located between the two back plates. The four vertical plates are respectively arranged at the four corners of the back plates.

[0018] A roller shaft is horizontally fixed between two vertical plates at the same end of the back plate, and the rollers are mounted on the roller shaft.

[0019] The guiding and sliding member is fixed relative to the back plate; the connecting rod, the two clamping members and the two mounting plates are all disposed between the two back plates.

[0020] Further, the linear motion actuator is an oil cylinder or an electric cylinder, its cylinder block is hinged to the fixed seat, and its telescopic rod is connected to the frame through a hinge seat.

[0021] Further, the roller is a bearing.

[0022] Further, the length of the pull rod can be adjusted.

[0023] Applied to the control method of the above multi-dimensional profiling cutter bar, the control method is implemented by the controller, and the control method includes:

[0024] Step S1), receiving a control instruction, the control instruction including a target operation mode;

[0025] Step S2), comparing the target operation mode with the current operation mode, and determining whether the state of each state switching mechanism needs to be changed;

[0026] Step S3), controlling the state switching mechanism whose state needs to be changed to operate to complete the switching of its state.

[0027] Further, the controlling the state switching mechanism whose state needs to be changed to operate includes:

[0028] When it is necessary to switch the state switching mechanism from the working state to the idle state, first control the linear motion actuator to retract until the profiling wheel on the corresponding side establishes a support for the cutter bar frame, and then control the locking mechanism to switch from the locked state to the unlocked state;

[0029] When it is necessary to switch the state switching mechanism from the idle state to the working state, first control the locking mechanism to switch from the unlocked state to the locked state, and then control the linear motion actuator to extend to lift the corresponding side of the cutter bar frame.

[0030] Beneficial effects: The multi-dimensional profiling cutter bar and its control method of the present invention have the following advantages:

[0031] (1) By setting two sets of state switching mechanisms on the left and right and redesigning the connection structure between the cutter bar frame and the machine frame, the cutter bar frame has more adjustment dimensions relative to the machine frame. Cooperating with the two sets of state switching mechanisms arranged on the left and right, the cutter bar can be switched between three usage modes: full profiling mode, lifting mode, and single-sided profiling mode. The single-sided profiling mode can be applied to special situations such as encountering drainage ditches, and the lifting mode and the single-sided profiling mode can also achieve special working conditions such as the need to perform lateral torsion operations on the cutter bar frame, meeting more usage requirements.

[0032] (2) The state switching mechanism is redesigned, and the switching between the locked state and the unlocked state is realized by energizing and de-energizing the electromagnet to establish or disconnect the connection between the linear motion actuator and the cutter bar frame. The mechanism has high reliability, no jamming problem, and is convenient for the controller to control. Brief Description of the Drawings

Detailed Embodiment

[0041] The present invention will be further described below with reference to the accompanying drawings.

[0042] AsFigures 1 - 3 The shown multi - dimensional profiling cutting platform includes a frame 5 and a cutting platform frame body 6. The cutting platform frame body 6 can move with multiple degrees of freedom relative to the frame 5, and a state - switching mechanism A is connected between the two. The state - switching mechanism A includes a linear - motion execution element 3 and a locking mechanism 2. On the left and right sides of the front end of the cutting platform frame body 6, profiling wheels 7 are respectively installed. The state - switching mechanism A is controlled by a controller B to operate.

[0043] There are two groups of the above - mentioned state - switching mechanisms A, namely left and right, arranged between the frame 5 and the cutting platform frame body 6. On the frame 5, there is an intermediate connection seat 5a connecting the cutting platform frame body 6 and two side connection seats 5b located on the left and right sides of the intermediate connection seat 5a. The middle part of the rear side of the cutting platform frame body 6 is connected to the intermediate connection seat 5a through a spherical bearing. The two side connection seats 5b are respectively connected to the cutting platform frame body 6 through tie rods 8. Both ends of the tie rod 8 are connected to the side connection seat 5b and the cutting platform frame body 6 through spherical bearings respectively.

[0044] The above - mentioned two groups of state - switching mechanisms A are respectively placed on the left and right sides of the intermediate connection seat 5a to act on the left and right sides of the cutting platform frame body 6 respectively. The locking mechanism 2 can switch between a locked state and an unlocked state. In the locked state, the locking mechanism 2 is fixed relative to the cutting platform frame body 6, and the operation of the linear - motion execution element 3 can drive the corresponding side of the cutting platform frame body 6 to lift. In the unlocked state, the locking mechanism 2 does not restrict the cutting platform frame body 6, and the corresponding side of the cutting platform frame body 6 makes a profiling movement under the support of the profiling wheel 7.

[0045] In actual use, a harvesting execution mechanism, such as a reel, a cutter group, a conveying mechanism, etc., can be installed on the above - mentioned cutting platform frame body 6. With the above structure, the cutting platform frame body 6 can perform multi - dimensional movements with its connection point with the intermediate connection seat 5a. Compared with the traditional main frame body of the cutting platform that can only pitch and rotate, in this application, the cutting platform frame body 6 can not only pitch and rotate relative to the frame 5, but also swing left and right, making the left and right sides of the cutting platform frame body 6 at different heights. Cooperating with the left and right two groups of state - switching mechanisms A, multi - mode switching of the cutting platform state can be realized.

[0046] Specifically, the above - mentioned cutting platform can realize the following three operation modes:

[0047] Mode 1: Full - profiling mode. In this mode, the locking mechanisms 2 of the two groups of state - switching mechanisms A are both in the unlocked state. The two groups of state - switching mechanisms A do not produce any constraints on the cutting platform frame body 6. The profiling wheels 7 on both sides of the cutting platform frame body 6 are in contact with the ground, and the profiling wheels 7 on both sides make the two sides of the cutting platform perform profiling movements respectively. Correspondingly, the cutting platform frame body 6 swings left and right relative to the frame 5 to adapt to the terrain of the ground. Compared with the traditional profiling structure, the cutting platform in this state of this application can fit the actual terrain better.

[0048] Mode 2: Lifting mode. In this mode, the locking mechanisms 2 of the two sets of state switching mechanisms A are both in the locked state. Through the linear motion actuators 3 of the two sets of state switching mechanisms A, the profiling wheels 7 on both sides of the cutter bar frame 6 can be lifted off the ground, completely lifting the cutter bar frame 6, so that the harvesting mechanism on the cutter bar frame 6 can harvest the higher positions of the crops.

[0049] Mode 3: Single-sided profiling mode. In this mode, the locking mechanism 2 of one set of state switching mechanisms A is in the locked state, and the corresponding profiling wheel 7 is in contact with the ground; the locking mechanism 2 of the other set of state switching mechanisms A is in the unlocked state, and the corresponding profiling wheel 7 is lifted off the ground, and the linear motion actuator 3 supports the corresponding side of the cutter bar frame 6. This mode is applicable to the situation where one of the profiling wheels 7 just encounters a water ditch, and the corresponding side of the cutter bar frame 6 can be lifted to keep the cutter bar frame 6 from tilting at a large angle and ensure the smooth progress of the harvesting operation.

[0050] Preferably, as Figure 4 shown, the state switching mechanism A further includes a connecting rod 1, and the connecting rod 1 is fixed on the cutter bar frame 6; the locking mechanism 2 is installed around the connecting rod 1; the locking mechanism 2 can be switched between the locked state and the unlocked state; in the locked state, the locking mechanism 2 is fixed relative to the connecting rod 1, and in the unlocked state, the locking mechanism 2 can slide relative to the connecting rod 1;

[0051] As Figures 5 - 6 shown, the locking mechanism 2 includes a frame 21 arranged around the connecting rod 1; a roller 22 and a clamping member 23 are installed on the frame 21; the roller 22 is always in contact with the connecting rod 1, and the rollers 22 are arranged in pairs, and the two rollers 22 in the same pair are respectively arranged on both sides of the connecting rod 1. The linear motion actuator 3 is an oil cylinder or an electric cylinder, and its cylinder seat 31 is hinged on the fixed seat 4 through a spherical bearing, and its telescopic rod 32 is connected to the frame 21 through a hinge seat 33, and a spherical bearing is also connected between the telescopic rod 32 and the hinge seat 33. The fixed seat 4 is fixedly installed relative to the machine frame 5 (the machine frame 5 is not fully shown in the figure).

[0052] The two clamping members 23 are respectively arranged on both sides of the connecting rod 1; the locking mechanism 2 further includes an elastic mechanism; in the locked state, the clamping member 23 is in contact with the connecting rod 1; in the unlocked state, the elastic mechanism makes there be a gap between each clamping member 23 and the connecting rod 1, that is, the width of the gap between the two clamping members 23 is greater than the thickness h of the connecting rod 1; the linear motion actuator 3 is connected to the fixed seat 4 and the frame 21, and the fixed seat 4 is fixed on the machine frame 5.

[0053] Using the above structure, in the unlocked state, the roller 22 contacts the connecting rod 1, and the locking mechanism 2 slides smoothly relative to the connecting rod 1 with very little resistance, which will not affect the movement of the movable part of the cutter bar. In the locked state, the two clamping members 23 are in close contact with the surface of the connecting rod 1, and the frictional force between the clamping member 23 and the connecting rod 1 fixes the locking mechanism 2 relative to the connecting rod 1. In this way, the linear motion actuator 3 can push the movable part of the cutter bar through the locking mechanism 2 and the connecting rod 1 to control the attitude of the cutter bar. The above cutter bar state switching mechanism A is in the form of a module, which is convenient to be integrated into agricultural machinery, easy to install and use, and can be promoted as an agricultural machinery accessory.

[0054] The cross-section of the above-mentioned connecting rod 1 is square, and the frame 21 is also a square frame; the locking mechanism 2 includes two pairs of the rollers 22, and the two pairs of the rollers 22 are respectively arranged at both ends of the clamping member 23. In this way, the layout of the rollers 22 is reasonable, and the entire frame 21 can be symmetrically supported, improving the smoothness of the movement between the locking mechanism 2 and the connecting rod 1 in the unlocked state. The symmetrically supported rollers 22 also play a role of support and isolation, and can keep a gap between the two clamping members 23 and the connecting rod 1 in the unlocked state. The roller 22 is a bearing, and the bearing has the advantages of low cost, small rolling resistance, and high surface hardness.

[0055] The clamping member 23 is an electromagnet. The clamping member 23 is installed on the mounting plate 24, and the mounting plate 24 can slide relative to the frame 21 under the action of the guiding member 25. A spring 26 is sleeved on the guiding member 25, and the spring 26 is placed between the two mounting plates 24 corresponding to the two clamping members 23.

[0056] Preferably, the frame 21 is composed of two back plates 21a and four vertical plates 21b located between the two back plates 21a. The four vertical plates 21b are respectively arranged at the four corners of the back plate 21a; a roller shaft 27 is horizontally fixed between the two vertical plates 21b at the same end of the back plate 21a, and the roller 22 is installed on the roller shaft 27; the guiding member 25 is fixed relative to the back plate 21a; the connecting rod 1, the two clamping members 23 and the two mounting plates 24 are all arranged between the two back plates 21a. The above frame 21 has a firm structure and reasonable layout, and has high reliability. The guiding member 25 is a double-headed screw, the middle section of which is a smooth rod structure, and nuts 28 pressing the back plate 21a are connected to both ends thereof.

[0057] Preferably, the length of the pull rod 8 can be adjusted. In this way, the initial attitude of the cutter bar frame 6 can be conveniently adjusted.

[0058] Such as Figure 7Shown is a control method applied to the above-mentioned multi-dimensional profiling cutter bar, which is implemented by the controller B. The control method includes:

[0059] Step S1), receiving a control instruction, the control instruction including a target operation mode;

[0060] Step S2), comparing the target operation mode with the current operation mode to determine whether the state of each state switching mechanism A needs to be changed; specifically, when converting between the full profiling mode and the lifting mode, the states of both state switching mechanisms A need to be changed. When converting between the full profiling mode and the single-sided profiling mode, and when converting between the lifting mode and the single-sided profiling mode, only the state of one state switching mechanism A needs to be changed.

[0061] Step S3), controlling the state switching mechanism A whose state needs to be changed to operate to complete the switching of its state, so as to complete the switching of the cutter bar operation mode.

[0062] Preferably, controlling the state switching mechanism A whose state needs to be changed to operate includes:

[0063] When it is necessary to switch the state switching mechanism A from the working state to the idle state, first control the linear motion actuator 3 to retract until the profiling wheel 7 on the corresponding side establishes support for the cutter bar frame 6, and then control the locking mechanism 2 to switch from the locked state to the unlocked state, that is, the electromagnet is powered off; thereafter, the corresponding side of the cutter bar frame 6 rises and falls with the undulation of the profiling wheel 7.

[0064] When it is necessary to switch the state switching mechanism A from the idle state to the working state, first control the locking mechanism 2 to switch from the unlocked state to the locked state, that is, the electromagnet is powered on, and then control the linear motion actuator 3 to extend to lift the corresponding side of the cutter bar frame 6, so that the profiling wheel 7 on the corresponding side of the cutter bar frame 6 leaves the ground.

[0065] In addition, a sensor for detecting the lateral inclination of the cutter bar frame 6 can be installed on the cutter bar frame 6. When performing the single-sided profiling mode, the profiling wheel 7 on one side of the cutter bar frame 6 touches the ground, and the profiling wheel 7 on the other side leaves the ground and is supported by the state switching mechanism A on that side (the state switching mechanism A on that side is in the working state). The controller B can adjust according to the lateral inclination measured by the sensor, and accordingly control the linear motion actuator 3 of the state switching mechanism A in the working state to dynamically extend and retract to keep the lateral inclination of the cutter bar frame 6 within a preset range, so as to ensure that the harvesting operation can be carried out normally and can fully profile the ground.

[0066] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
