Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to a pedal-hand-controlled dual-clutch operating mechanism and a riding micro-tillage machine using the clutch mechanism. Background Art

[0002] Currently, the mainstream micro-tillage machines on the market are mainly hand-held micro-tillage machines. This type of hand-held micro-tillage machine requires people to follow behind the micro-tillage machine to push it to operate, which has high labor intensity and low operating efficiency.

[0003] In order to reduce labor intensity and improve operating efficiency, some four-wheel ride-on micro-tillage machines have gradually appeared on the market. They have a seat for the operator to sit on the micro-tillage machine, a foot pedal for controlling the engagement or disengagement of the clutch is provided at the lower end of the seat, and a rear clutch control mechanism is provided at the rear end of the seat. When encountering ditches or bumpy roads, the driver can leave the driving seat and control the engagement or disengagement of the clutch by operating the rear clutch control mechanism. For example, a Chinese patent with application number 2023107981036 discloses a clutch operating mechanism, including a first operating part, the first operating part includes a clutch control foot pedal for stepping on when riding and driving, the clutch control foot pedal is connected to the clutch fork shaft, and the clutch control foot pedal can drive the clutch fork shaft; a second operating part, the second operating part includes a handle, a clutch control handle assembly, a control cable and a control rod, the clutch control handle assembly is arranged on the handle, the handle is arranged on the back of the backrest, and the handle can be rotated along a vertical plane to an unfolded or folded state on one side of the micro-tiller; one end of the control cable is connected to the clutch control handle assembly, and the other end of the control cable is connected to one end of the control rod, the clutch control handle assembly can drive the control rod through the control cable, and drive the clutch fork shaft through the control rod.

[0004] In the clutch operating mechanism of the above-mentioned riding micro-tillage machine, the rotation of the foot pedal is used to drive the clutch fork shaft to rotate, thereby realizing the engagement of the clutch. The foot pedal requires a large force to rotate into place, and it is easy to cause fatigue to the operator after long-term stepping. At the same time, when the operator of the above-mentioned riding micro-tillage machine is sitting on the seat, the clutch can only be achieved through the foot pedal. The clutch control handle is installed on the handle on the back of the seat back and cannot be operated on the seat. In the actual operation process, if the foot pedal is stepped on for a long time to achieve clutch, fatigue is easy to occur, and the existing manual clutch is located behind the backrest and cannot be used as a replacement after being tired. In addition, in order to facilitate the operator to get on and off, the existing riding micro-tillage machine has no side protection and no handholds. It is easy to fall off the seat on turns or bumpy roads, causing safety hazards. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a foot-operated hand-controlled dual-clutch operating mechanism and a ride-on micro-tillage machine using the clutch mechanism, so as to solve the problems that the existing ride-on micro-tillage machines have a single clutch control mode during driving operation, the side of the driver's seat is unprotected, and fatigue easily occurs after long-term operation in the driver's seat, posing a safety hazard.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: A pedal-operated hand-controlled dual-clutch operating mechanism comprises a pedal-operated operating component and a hand-operated operating component for controlling the clutch to be disconnected or engaged. The hand-controlled control assembly includes an armrest mounting seat, a safety armrest and a clutch control handle assembly. The armrest mounting seat is fixedly mounted on one side of the seat bracket of the micro-tiller. The safety armrest is rotatably mounted on the armrest mounting seat and can be rotated forward and backward around the armrest mounting seat and positioned; the clutch control handle assembly is detachably mounted on the safety armrest; The foot-operated control assembly includes a foot pedal and a foot pedal mounting seat, wherein the foot pedal is arranged in an inclined manner, the front end of the foot pedal is connected to the foot pedal mounting seat through a linkage, and the rear end is rotatably mounted on the foot pedal mounting seat; a strip hole is arranged at the front end of the foot pedal mounting seat, a linkage shaft is arranged in the strip hole, the rear end of the linkage is arranged upwardly inclined, and is rotatably connected to the lower side of the foot pedal, and the front end is rotatably connected to the linkage shaft; a clutch cable is connected to the linkage shaft, and the foot pedal mounting seat can be rotated downward under the action of an external force, and can drive the linkage shaft to roll forward along the strip hole to drive the fork arm at the end of the clutch cable; after the external force is released, the foot pedal can be rotated upward at the front end to return to the initial position under the reaction of the clutch tension. In this way, when the driver sits on the seat, he can step on the foot pedal downward with his foot, so that the foot pedal rotates downward, and then drives the clutch cable to slide, thereby realizing the engagement of the clutch. After the foot is tired, the driver can directly hold the clutch control handle assembly with his hand to achieve clutch, that is, it can meet the two clutch controls during normal driving. The safety armrest rotates forward and is horizontal, which can be used as a side block for the driver. The driver can hold the safety armrest with one hand, so that there is a side block and a force armrest during turning or driving, which prevents the driver from falling off the seat due to not sitting firmly. At the same time, when encountering bumpy roads or ditches and the driver needs to get off the machine to operate, the safety armrest is rotated backward and locked in place, and then the driver goes around the tiller to achieve clutch by holding the clutch control handle assembly. At this time, the safety armrest is tilted backward and away from the seat, with a large operating space and convenient operation. At the same time, the safety armrest can also be held by people, and the operation is more stable. The safety armrest can be rotatably installed on the armrest mounting seat, and can be positioned after rotating to the required angle, so as to meet the needs of different working conditions.

[0007] The foot pedal in the foot-operated control assembly is tilted, with the front end tilted upward and the rear end rotatably connected to the foot pedal mounting seat. The lower side of the front end is rotatably connected to the diameter of the foot pedal mounting seat through a linkage shaft, and the linkage shaft is placed in the strip hole, so that when the operator steps on the foot pedal downward, the foot pedal rotates downward, and the linkage also rotates downward during the downward rotation of the foot pedal, and during the rotation process, it drives the linkage shaft connected to it to slide forward, thereby pulling the clutch cable connected to the linkage shaft forward, and finally pulling the fork arm to achieve clutch connection. In this process, a connecting rod transmission mechanism is formed between the foot pedal and the linkage, and only a small force is needed to ensure the sliding of the linkage shaft, and after sliding to the position limit of the end of the strip hole, the current state is maintained. During the maintenance process, only a small force is needed to stabilize the linkage shaft in the current state, so as to achieve the purpose of labor saving. After long-term pedaling, fatigue is not easy to occur, and a semi-clutch state due to the pedal not being stepped on firmly is avoided. At the same time, since the force required for the linkage shaft is small, the reaction force required for returning to the original position is also small, and there is no need to set up a separate spring. The clutch can be returned to the original position only by the reaction force of the clutch tension. Therefore, when the clutch needs to be disconnected, the operator removes his foot from the foot pedal. The foot pedal is not released by external force at this time, and the reaction force of the clutch tension can be transmitted to the linkage shaft through the clutch cable, pulling the linkage shaft to slide backward, so that the foot pedal can be quickly reset.

[0008] Furthermore, the handrail mounting seat is in the shape of a plate, and a mounting plate is fixedly mounted on one end of the safety handrail near the handrail mounting seat, and the mounting plate is placed outside the handrail mounting seat and is rotatably connected via a rotating pin. In this way, after the safety handrail is pulled under the action of an external force, the mounting plate connected thereto can rotate around the rotating pin.

[0009] Furthermore, an arc-shaped guide hole is provided in the middle part of the handrail mounting seat, and a positioning screw with one end passing through the arc-shaped guide hole is installed on the mounting plate, and a positioning nut matching the positioning screw is provided on the positioning screw and on one side of the handrail mounting seat; the center of the moving path of the positioning screw in the arc-shaped guide hole overlaps with the center of the rotating pin; the positioning screw rotates under the action of external force, and after axial movement, if the distance between its nut and the positioning nut is greater than the sum of the thicknesses of the handrail mounting seat and the mounting plate, the safety handrail is in an active state; if the distance between the nut of the positioning screw and the positioning nut is equal to the sum of the thicknesses of the handrail mounting seat and the mounting plate, the safety handrail is in a locked and fixed state. In this way, when in use, by rotating the positioning screw, the distance between the nut of the screw and the positioning nut is changed. When the distance between the positioning nut and the nut is equal to the sum of the thickness of the mounting plate and the handrail mounting seat, the mounting plate and the handrail mounting seat are clamped and fixed between the nut and the positioning nut of the positioning screw. After the mounting plate is locked and fixed, the safety handrail fixedly connected thereto is also locked and positioned accordingly. When the positioning screw is rotated in the opposite direction to increase the distance between the nut and the positioning nut, there is a gap between the handrail mounting seat and the mounting plate, between the mounting plate and the nut, and between the handrail mounting seat and the positioning nut. At this time, when the safety handrail is pulled, the positioning screw can move along the arc guide hole with the rotating pin as the center of the circle. The arc guide hole provided can guide the positioning screw, and at the same time, together with the rotating pin, realize the two-point positioning of the mounting plate, so that the fixing structure of the mounting plate is stable when locked. The length setting of the arc guide hole can limit the maximum rotation angle of the safety handrail, which is convenient for the driver to operate.

[0010] Furthermore, the clutch control handle assembly includes a mounting seat and a handlebar rotatably mounted on the mounting seat, and a hand-controlled clutch cable is connected to the handlebar; the mounting seat is fixedly mounted on the safety handrail by a fastener. In this way, the clutch control handle assembly can be detachably mounted on the safety handrail, and installation, adjustment and maintenance are convenient. The clutch cable is connected to the clutch fork, and when the handlebar is held inward, the clutch cable can be pulled to achieve clutch engagement, and after the handlebar is released, the clutch can be disconnected.

[0011] Further, the pedal mounting seat includes a bottom plate and two vertical plates vertically fixed on the bottom plate, the two vertical plates are parallel to each other and arranged along the length direction of the bottom plate, and the strip holes are provided with two, which are respectively arranged at the front ends of the two vertical plates; the linkage member includes a linkage plate, and the left and right sides of the linkage plate near the end of the pedal extend toward the pedal direction to form an upper link plate, and the left and right sides of the linkage plate near the end of the pedal mounting seat extend toward the vertical plate direction to form a lower link plate; the linkage member and the pedal mounting seat can be rotatably connected after the linkage shaft passes through the lower link plate and extends out of the corresponding side strip holes. In this way, the pedal mounting seat is composed of the bottom plate and the two vertical plates, and the structure is stable. The vertical plates can facilitate the setting of the strip holes, and provide two points of force for the linkage shaft, so that the sliding of the linkage shaft in the strip hole is more stable. Correspondingly, the linkage member is plate-shaped and has a stable structure. The lower link plates formed on the left and right sides of the linkage plate can be arranged adjacent to the two vertical plates, and can be rotatably connected after the linkage shaft is passed through as a rotating shaft. There are two rotation points between the linkage and the pedal mounting seat, so the rotation process is more stable.

[0012] Furthermore, two spaced-apart connecting ears are provided on the lower end surface of the front end of the foot pedal, and two spaced-apart rotating ears are provided on the lower end surface of the rear end of the foot pedal. The two connecting ears are placed between the two upper connecting plates and are rotatably connected to the connecting member through the first rotating shaft; the two rotating ears are placed between the two vertical plates and are rotatably connected to the foot pedal mounting seat through the second rotating shaft. In this way, the connecting ears of the foot pedal are correspondingly arranged with the upper connecting plates of the connecting member. After being rotatably connected through the first rotating shaft, the upper end of the connecting member also has two rotating points, and the rotation is stable. The connecting member between the foot pedal and the foot pedal mounting seat has four connection points, and the operation is very stable. The connecting ears and rotating ears provided on the foot pedal can facilitate the connection between the foot pedal and the connecting member and the foot pedal mounting seat.

[0013] Furthermore, a cable adjustment seat is provided on the bottom plate of the pedal mounting seat, and the middle part of the clutch cable passes through the cable adjustment seat and is connected to the fork arm. In this way, after the cable adjustment seat is provided, the length of the cable can be adjusted as needed in actual operation to meet the clutch requirements.

[0014] Furthermore, four mounting holes distributed in a rectangular shape are provided on the bottom plate, so that the provided mounting holes can facilitate the fixed installation of the bottom plate.

[0015] A riding micro-tillage machine includes a power assembly, a gearbox and a clutch operating mechanism, wherein the power assembly is connected to the gearbox through a clutch transmission, and the clutch operating mechanism is used to control the engagement or disengagement of the clutch, and includes a foot-operated operating component and a hand-operated operating component, wherein the foot-operated operating component and the hand-operated operating component are as described above. In this way, the riding micro-tillage machine of the present invention can be used in different working conditions, and has a simple overall structure and is easy to operate.

[0019] like Figure 1-Figure 8 As shown, the pedal-operated hand-operated dual-clutch operating mechanism provided in this embodiment includes a pedal-operated operating component 4 and a hand-operated operating component 3 for controlling the clutch to be disconnected or engaged. The hand-controlled control assembly 3 includes an armrest mounting seat 31, a safety armrest 32 and a clutch control handle assembly 36. The armrest mounting seat 31 is fixedly mounted on one side of the seat bracket of the micro-tiller. The safety armrest 32 is rotatably mounted on the armrest mounting seat 31 and can be rotated forward and backward around the armrest mounting seat 31 and positioned; the clutch control handle assembly 36 is detachably mounted on the safety armrest 32; The foot-operated control assembly 4 includes a foot pedal 42 and a foot pedal mounting seat 41. The foot pedal 42 is arranged at an angle. The front end of the foot pedal 42 is connected to the foot pedal mounting seat 41 through a connecting piece 43, and the rear end is rotatably mounted on the foot pedal mounting seat 41. A strip hole 413 is provided at the front end of the foot pedal mounting seat 41, and a connecting shaft 44 is provided in the strip hole 413. The rear end of the connecting piece 43 is arranged upwardly inclined and is rotatably connected to the lower side of the foot pedal 42, and the front end is rotatably connected to the connecting shaft 44. A clutch cable 45 is connected to the connecting shaft 44. When the foot pedal mounting seat 41 is rotated downward under the action of an external force, the connecting shaft 44 can be driven to roll forward along the strip hole 413 to drive the fork arm at the end of the clutch cable 45. After the external force is released, the foot pedal 42 can rotate upward at the front end under the reaction of the clutch tension and return to the initial position. In this way, when the driver sits on the seat, he can step on the foot pedal 42 downward, turn the foot pedal 42 downward, drive the clutch cable 45 to slide, and then realize the engagement of the clutch. After the foot is tired, the driver can directly hold the clutch control handle assembly 36 with his hand to realize the clutch, that is, it can meet the two clutch controls during normal driving. The safety armrest 32 rotates forward and is horizontal, which can be used as a side block for the driver, and the safety armrest 32 can be held by one hand, so that there is a side block and a force armrest during turning or driving, so as to prevent the driver from falling off the seat due to not sitting firmly. At the same time, when encountering a bumpy road section or a ditch, the driver needs to get off the machine to operate, and the safety armrest 32 is rotated backward and locked and positioned, and then after going around the micro-tillage machine, the clutch can be realized by holding the clutch control handle assembly 36. At this time, the safety armrest 32 is tilted backward, away from the seat, and the operation space is large and the operation is convenient. At the same time, the safety armrest 32 can also be held by people, and the operation is more stable. The safety handrail 32 can be rotatably mounted on the handrail mounting seat 31 and can be positioned after being rotated to a required angle, thereby being able to meet the requirements of different working conditions.

[0020] The foot pedal 42 in the foot-operated control assembly 4 is tilted, with the front end tilted upward and the rear end rotatably connected to the foot pedal mounting seat 41. The lower side of the front end is rotatably connected to the diameter of the foot pedal mounting seat 41 through a connecting member 43 and a connecting shaft 44, and the connecting shaft 44 is placed in the strip hole 413. When the operator steps on the foot pedal 42 downward, the foot pedal 42 rotates downward, and the connecting member 43 also rotates downward during the downward rotation of the foot pedal 42. During the rotation, the connecting shaft 44 connected thereto is driven to slide forward, thereby pulling the clutch cable 45 connected to the connecting shaft 44 forward, and finally pulling the fork arm to achieve the clutch connection. In this process, a connecting rod transmission mechanism is formed between the foot pedal 42 and the connecting member 43, and only a small force is needed to ensure that the connecting shaft 44 slides, and after sliding to the end position limit of the strip hole 413, the current state is maintained. During the maintenance process, only a small force is needed to stabilize the connecting shaft 44 in the current state, so as to achieve the purpose of labor saving. After long-term pedaling, fatigue is not easy to occur, and a semi-clutch state due to the pedal not being stepped on firmly is avoided. At the same time, since the force required for the connecting shaft 44 is small, the reaction force required for returning to the position is also small, and there is no need to set a spring separately, and the position can be returned only by the reaction force of the clutch tension. Therefore, when the clutch needs to be disconnected, the operator removes the foot from the foot pedal 42, and the foot pedal 42 is not released by external force at this time, that is, the reaction force of the clutch tension can be transmitted to the connecting shaft 44 through the clutch cable 45, and the connecting shaft 44 is pulled to slide backward, so that the foot pedal 42 is quickly reset.

[0021] like Figure 2-Figure 4 As shown, the handrail mounting seat 31 is in the shape of a plate, and a mounting plate 33 is fixedly mounted on one end of the safety handrail 32 close to the handrail mounting seat 31. The mounting plate 33 is placed outside the handrail mounting seat 31 and is rotatably connected via a rotating pin 34. The mounting plate 33 and the safety handrail 32 are fixed by welding (in specific implementation, they can also be fixed by fasteners). In this way, after the safety handrail 32 is pulled under the action of external force, the mounting plate 33 connected thereto can rotate around the rotating pin 34 as the center.

[0022] Furthermore, an arc-shaped guide hole 311 is provided in the middle of the handrail mounting seat 31, and a positioning screw 35 with one end passing through the arc-shaped guide hole 311 is installed on the mounting plate 33, and a positioning nut matching the positioning screw 35 is provided on the positioning screw 35 and on one side of the handrail mounting seat 31; the center of the moving path of the positioning screw 35 in the arc-shaped guide hole 311 overlaps with the center of the rotating pin 34; the positioning screw 35 rotates under the action of external force, and after axial movement, if the distance between its nut and the positioning nut is greater than the sum of the thicknesses of the handrail mounting seat 31 and the mounting plate 33, the safety handrail 32 is in an active state, and if the distance between the nut and the positioning nut of the positioning screw 35 is equal to the sum of the thicknesses of the handrail mounting seat 31 and the mounting plate 33, the safety handrail 32 is in a locked and fixed state. Thus, when in use, the spacing between the nut and the positioning nut of the screw is changed by rotating the positioning screw 35. When the spacing between the positioning nut and the nut is equal to the sum of the thickness of the mounting plate 33 and the handrail mounting seat 31, the mounting plate 33 and the handrail mounting seat 31 are clamped and fixed between the nut and the positioning nut of the positioning screw 35. After the mounting plate 33 is locked and fixed, the safety handrail 32 fixedly connected thereto is also locked and positioned accordingly. When the positioning screw 35 is rotated in the opposite direction to increase the spacing between the nut and the positioning nut, there are gaps between the handrail mounting seat 31 and the mounting plate 33, between the mounting plate 33 and the nut, and between the handrail mounting seat 31 and the positioning nut. At this time, when the safety handrail 32 is pulled, the positioning screw 35 can move along the arc guide hole 311 with the rotating pin 34 as the center of the circle. The arc-shaped guide hole 311 can guide the positioning screw 35, and at the same time, together with the rotating pin 34, realize the two-point positioning of the mounting plate 33, so that the mounting plate 33 is fixed and the structure is stable when locked. The length setting of the arc-shaped guide hole 311 can limit the maximum rotation angle of the safety handrail 32, which is convenient for the driver to operate.

[0023] Furthermore, the clutch control handle assembly 36 includes a mounting seat 361 and a turning handle 362 rotatably mounted on the mounting seat 361, and a manual clutch cable 363 is connected to the turning handle 362; the mounting seat 361 is fixedly mounted on the safety handrail 32 by fasteners. The clutch control handle assembly 36 in this embodiment is located at the lower end of the safety handrail 32 when the safety handrail 32 is facing forward and horizontal, and the operating assembly is located in front of the safety handrail 32 after the safety handrail 32 rotates backward and becomes inclined. In this way, the clutch control handle assembly 36 can be detachably mounted on the safety handrail 32, and installation, adjustment and maintenance are convenient. The manual clutch cable 363 is connected to the clutch fork, and when the turning handle is held inward, the manual clutch cable 363 can be pulled to achieve clutch engagement, and the clutch can be disconnected after the turning handle is released.

[0024] Furthermore, the footrest mounting seat 41 includes a bottom plate 411 and two vertical plates 412 vertically fixed on the bottom plate 411, the two vertical plates 412 are parallel to each other and arranged along the length direction of the bottom plate 411, and two strip holes 413 are provided, which are respectively arranged at the front ends of the two vertical plates 412; the connecting member 43 includes a connecting plate, and the left and right sides of the connecting plate near the foot pedal 42 extend toward the foot pedal 42 to form an upper connecting plate 431, and the left and right sides of the connecting plate near the foot pedal mounting seat 41 extend toward the vertical plates 412 to form a lower connecting plate 432; the connecting member 43 and the footrest mounting seat 41 are rotatably connected after the connecting shaft 44 penetrates the lower connecting plate 432 and extends out of the corresponding side strip holes 413. In a specific implementation, the left and right sides of the bottom plate 411 can be directly bent upward to form two vertical plates 412. This setting can also meet the installation requirements of the foot pedal 42 and the linkage plate, but it is not convenient to fix the bottom plate 411 on the protective cover of the micro-tiller. In this way, the foot pedal mounting seat 41 is composed of the bottom plate 411 and the two vertical plates 412, and the structure is stable. The vertical plates 412 can facilitate the setting of the strip hole 413, and provide two points of force for the linkage shaft 44, so that the sliding of the linkage shaft 44 in the strip hole 413 is more stable. Correspondingly, the linkage member 43 is plate-shaped and has a stable structure. The lower connecting plate 432 formed on the left and right sides of the linkage plate can be arranged adjacent to the two vertical plates 412, and can be rotatably connected after being penetrated by the linkage shaft 44 as a rotating shaft. There are two rotation points between the linkage member 43 and the foot pedal mounting seat 41, and the rotation process is more stable.

[0025] Furthermore, two spaced-apart connecting ears 421 are provided on the lower end surface of the front end of the foot pedal 42, and two spaced-apart rotating ears 422 are provided on the lower end surface of the rear end of the foot pedal 42. The two connecting ears 421 are placed between the two upper connecting plates 431 and are rotatably connected to the connecting member 43 through the first rotating shaft 46; the two rotating ears 422 are placed between the two vertical plates 412 and are rotatably connected to the foot pedal mounting seat 41 through the second rotating shaft 47. In this way, the connecting ears 421 of the foot pedal 42 are correspondingly arranged with the upper connecting plates 431 of the connecting member 43. After being rotatably connected through the first rotating shaft 46, the upper end of the connecting member 43 also has two rotating points, and the rotation is stable. The connecting member 43 between the foot pedal 42 and the foot pedal mounting seat 41 has four connection points, and the operation is very stable. The connecting ears 421 and the rotating ears 422 provided on the foot pedal 42 can facilitate the connection between the foot pedal 42 and the connecting member 43 and the foot pedal mounting seat 41.

[0026] Further, a cable adjustment seat is provided on the bottom plate 411 of the pedal mounting seat 41, and the middle part of the clutch cable 45 passes through the cable adjustment seat and is connected to the fork arm. In this way, after the cable adjustment seat is provided, the length of the cable can be adjusted as needed in actual operation to meet the clutch requirements.

[0027] Furthermore, four rectangularly distributed mounting holes are provided on the bottom plate 411. In this way, the provided mounting holes can facilitate the fixed installation of the bottom plate 411.
