Description

Technical Field

[0001] The invention relates to the technical field of gearboxes, in particular to a gearbox for a crawler self-propelled baler with multiple power outputs. Background Art

[0002] A crawler self-propelled baler is a self-powered agricultural machine that integrates power and baling device and uses a crawler walking device. Compared with a traction baler, a crawler self-propelled baler does not need to be towed by a tractor, but has its own power source and is usually equipped with an engine and a gearbox.

[0003] However, in practical applications, there are still some unresolved problems. The following are some common problems of crawler self-propelled baler gearboxes: In the prior art, the power output function of traditional gearboxes of crawler self-propelled balers has limitations. On the one hand, the coordination of multiple power outputs is poor, and soft power output (such as oil pump power) is easily affected by distance and angle changes during transmission, resulting in reduced efficiency or even failure. On the other hand, the connection between the engine and the gearbox lacks an effective clutch control mechanism, which requires the engine to overcome a large load torque when starting. This is a huge challenge for engines with small starting torque, which not only increases the difficulty of starting, but also easily causes excessive wear of the engine, reducing the reliability and economy of the equipment.

DETAILED DESCRIPTION

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0043] Example 1 Reference Figures 1 to 12 , which is the first embodiment of the present invention, and provides a gearbox for a crawler self-propelled baler with multiple power outputs. The gearbox for a crawler self-propelled baler with multiple power outputs comprises a gearbox mechanism 100, a drive mechanism 200 and a hydraulic assembly 201. The gearbox mechanism 100 can achieve good coordination during multiple power outputs, and can accurately cut off all power without stopping the engine. The hydraulic assembly 201 can transmit the drive mechanism 200, and then control the gearbox mechanism 100.

[0044] Specifically, the gearbox mechanism 100 includes a housing 101, a power input component 102, a soft power output component 103, a hard power output component 104 and a clutch control component 105. The power input component 102, the soft power output component 103, the hard power output component 104 and the clutch control component 105 are all arranged in the housing 101, and the soft power output component 103, the hard power output component 104 and the clutch control component 105 are arranged on the surface of the power input component 102.

[0045] The power input part 102, the soft power output part 103, the hard power output part 104 and the clutch control part 105 are all sealed with the housing 101. The housing 101 is composed of a box body and a box cover, and is designed according to actual conditions. The power input part 102 provides power to the soft power output part 103 and the hard power output part 104. When the soft power output part 103 outputs, it adopts flexible shaft transmission technology combined with an adjustable universal joint structure to ensure that the power output by the two oil pumps can be stably transmitted without being restricted by distance and angle. The hard power output part 104 uses high-precision gear processing and shaft assembly technology to ensure that the power output of the shaft is strong and stable.

[0046] The clutch control component 105 adopts a combination of hydraulic clutch and mechanical clutch. Through the operating handle, the hydraulic system drives the separation and combination of the clutch plate to achieve accurate cutting off of all power without stopping the engine. At the same time, when the engine is started, it ensures that the clutch 102d is in a completely disengaged state, reducing the starting torque requirement, allowing the engine to start easily, and improving the overall operating efficiency and reliability of the equipment.

[0047] Specifically, the driving mechanism 200 is installed on the surface of the housing 101 and the clutch control member 105 , and includes a connecting plate 202 , a first cover body 203 and a second cover body 204 . The connecting plate 202 is arranged on the surface of the clutch control member 105 .

[0048] The connecting plate 202 is driven by the telescopic piston rod 201c on the hydraulic component 201, thereby operating the clutch control component 105 to achieve the separation and combination of the clutch plate. The first cover body 203 and the second cover body 204 are used to shield some components on the hydraulic component 201 to avoid damage by impact.

[0049] Specifically, the hydraulic component 201 is arranged on the surface of the shell 101, the first cover body 203 and the second cover body 204 are arranged on the surface of the hydraulic component 201, including a cylinder 201a, a piston 201b, a piston rod 201c, a cover body 201d, a ring plate 201e and a sealing sleeve 201f, the cylinder 201a is fixedly connected to the surface of the shell 101, the piston 201b is slidably connected in the cylinder 201a, the piston rod 201c is fixedly connected to the surface of the piston 201b, the cover body 201d is arranged at the bottom of the cylinder 201a, the cover body 201d is sleeved on the surface of the piston rod 201c, the ring plate 201e is fixedly connected to the surface of the cylinder 201a, the sealing sleeve 201f is sleeved on the surface of the piston rod 201c and is movably connected to the surface of the cover body 201d, and the lower end of the piston rod 201c is rotatably connected to one end of the connecting plate 202.

[0050] A sealing gasket is arranged between the cylinder 201a and the cover 201d, and a sealing ring is arranged between the piston 201b and the cylinder 201a. The amount of hydraulic oil in the two chambers of the cylinder 201a is controlled by the hydraulic system, and the movement of the piston 201b and the piston rod 201c is controlled, thereby controlling the connecting plate 202 to rotate and adjust the wrench 105d, and sealing the piston rod 201c and the cover 201d through the sealing sleeve 201f.

[0051] Specifically, the hydraulic assembly 201 also includes a fixing part 201g, a holding part 201h, a cleaning part 201i, a lubricating part 201j and a positioning column 201k. The fixing part 201g is arranged on the surface of the cylinder 201a, the ring plate 201e and the cover body 201d. The holding part 201h is arranged on the surface of the cover body 201d and the fixing part 201g. The cleaning part 201i is arranged on the surface of the cover body 201d. The lubricating part 201j is arranged in the cover body 201d. The positioning column 201k is fixedly connected to the top of the cover body 201d. A positioning groove cooperating with the positioning column 201k is opened at the bottom of the ring plate 201e, and the positioning column 201k is inserted into the positioning groove.

[0052] The fixing part 201g facilitates quick disassembly and assembly between the cylinder 201a and the cover 201d, thereby facilitating maintenance and replacement of parts, and when replacing the hydraulic oil, it is convenient to clean out the residue in the cylinder 201a. The installed sealing sleeve 201f is pressed by the holding part 201h to improve the sealing efficiency between it and the piston rod 201c, avoiding long-term wear and tear so that it cannot be in close contact with the surface of the piston rod 201c.

[0053] Before removing the cleaning piece 201i between the cylinder 201a and the cover 201d, the surface of the moving piston rod 201c is cleaned and prevented from entering the hydraulic cylinder cylinder 201a by the filter 201i-6, which is convenient for subsequent processing. The surface of the moving piston rod 201c can be lubricated by the lubricating piece 201j to reduce the friction between it and the sealing sleeve 201f, protect the surface of the piston rod 201c and reduce wear. The cylinder 201a and the cover 201d are initially positioned by the positioning column 201k and the positioning groove, so as to facilitate the accurate buckle plate 201g-3 on the fixing piece 201g to the corresponding position of the cover 201d.

[0054] Example 2 Reference Figure 2 to Figure 10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0057] The soft power output member 103 includes a first output shaft 103a and a second gear 103b. The first output shaft 103a is rotatably connected to the inner surface of the housing 101.

There are two second gears 103b, and they are respectively fixedly connected to the surfaces of the two first output shafts 103a, thereby forming two soft power outputs. When the first gear 102c rotates to drive the two second gears 103b to rotate, the two first output shafts 103a can be rotated. During output, flexible shaft transmission technology combined with an adjustable universal joint structure is used to connect with the outside world, ensuring that the power output by the two oil pumps can be stably transmitted without being restricted by distance and angle.

The rotation of the first gear 102c drives the third gear 104c to rotate, thereby rotating the first shaft 104a and the fourth gear 104d, and then rotating the fifth gear 104e, the first bevel gear 104f and the second shaft 104b, and then rotating the second bevel gear 104h and the second output shaft 104g. Through high-precision gear processing and shaft assembly technology, the power output of the shaft is guaranteed to be strong and stable, and hard power output is achieved.

[0061] The clutch control component 105 includes a shift lever 105a, a fork component 105b, a shift rod 105c and a wrench 105d. The shift lever 105a is fixedly connected to the inner wall of the housing 101. The fork component 105b is arranged on the surfaces of the shift lever 105a, the clutch 102d and the shift rod 105c.

At the same time, when the engine is started, it is ensured that the clutch 102d is in a completely disengaged state, reducing the starting torque requirement and allowing the engine to start easily.

[0063] Example 3 Reference Figures 12 to 20 , which is the third embodiment of the present invention, and is based on the first two embodiments.

The movable sleeve 201g-1 is sleeved on the surface of the cylinder 201a, the movable plate 201g-2 is rotatably connected to the surface of the movable sleeve 201g-1, the buckle plate 201g-3 is rotatably connected to the surface of the ring plate 201e, one end of the movable plate 201g-2 is rotatably connected to one end of the buckle plate 201g-3, and the buckle plate 201g-3 is buckled on the cover The surface of the body 201d, the limit member 201g-4 is arranged on the surface of the cylinder 201a, the first clamping block 201g-5 is slidably connected to the surface of the movable sleeve 201g-1, the turntable 201g-7 is rotatably connected to the surface of the ring plate 201e, the extrusion block 201g-8 is fixedly connected to the surface of the turntable 201g-7, the two ends of the second spring 201g-9 are respectively fixedly connected to the movable sleeve 201g-1 and the surface of the ring plate 201e, the guide block 201g-6 is fixedly connected to the surface of the cylinder 201a, the guide block 201g-6 is slidably connected to the movable sleeve 201g-1, and the first cover body 203 is fixedly connected to the surface of the movable sleeve 201g-1.

[0065] The movable sleeve 201g-1 is slidably connected to the surface of the cylinder 201a. A through hole cooperating with the first clamping block 201g-5 is provided on the surface of the movable sleeve 201g-1. The first clamping block 201g-5 is slidably connected in the through hole. An arc hole cooperating with the extrusion block 201g-8 is provided on the surface of the ring plate 201e. The extrusion block 201g-8 is slidably connected in the arc hole. A guide hole cooperating with the guide block 201g-6 is provided on the inner surface of the movable sleeve 201g-1. The guide block 201g-6 is slidably connected in the guide hole. The movement of the movable sleeve 201g-1 is guided and limited by the guide hole and the guide block 201g-6 to prevent it from rotating.

[0066] The movable sleeve 201g-1 is movably connected to the ring plate 201e, and one end of the first clamping block 201g-5 extends to the inner wall of the arc-shaped hole. The first clamping block 201g-5 is inserted into the arc-shaped hole on the ring plate 201e to fix the movable sleeve 201g-1 and the ring plate 201e. The limiting member 201g-4 can be used to limit and fix the movable sleeve 201g-1 when it is moved and inserted into the ring plate 201e. By rotating the turntable 201g-7, the extrusion block 201g-8 can be driven to rotate, so that it squeezes and moves the first clamping block 201g-5, so that the first clamping block 201g-5 can be separated from the arc-shaped hole.

[0067] Then the first clamping block 201g-5 acts on the limiting member 201g-4, losing the limiting position on the movable sleeve 201g-1, and is compressed by the second spring 201g-9 when the movable sleeve 201g-1 moves toward the ring plate 201e. Then, during disassembly, the first clamping block 201g-5 is separated from the arc hole, and the limiting member 201g-4 loses the limiting position on the movable sleeve 201g-1, providing power for the reset of the movable sleeve 201g-1, thereby separating the buckle plate 201g-3 from the cover body 201d.

[0068] The holding member 201h includes a groove body 201h-1, a slider 201h-2, a fourth spring 201h-3, a support plate 201h-4, a rotating rod 201h-5, a pressure plate 201h-6, a torsion spring 201h-7, a sixth gear 201h-8 and a tooth 201h-9. The groove body 201h-1 is opened in the cover body 201d, the slider 201h-2 is slidably connected to the groove body 201h-1, the two ends of the fourth spring 201h-3 are respectively fixedly connected to the inner wall of the groove body 201h-1 and the surface of the slider 201h-2, the support plate 201h-4 is fixedly connected to the surface of the slider 201h-2, the support plate 201h-4 is sleeved on the surface of the cover body 201d, and the rotating rod 201h-5 is rotatably connected to the cover body 201d. On the surface of the support plate 201h-4, the pressure plate 201h-6 is fixedly connected to the lower end of the rotating rod 201h-5, the torsion spring 201h-7 is sleeved on the surface of the rotating rod 201h-5, and the two ends of the torsion spring 201h-7 are respectively fixedly connected to the pressure plate 201h-6 and the surface of the support plate 201h-4, the sixth gear 201h-8 is fixedly connected to the upper end of the rotating rod 201h-5, the tooth 201h-9 is fixedly connected to the surface of the turntable 201g-7, the sixth gear 201h-8 is meshed with the tooth 201h-9, the second cover body 204 is fixedly connected to the bottom of the support plate 201h-4, the slider 201h-2 is movably connected to the buckle plate 201g-3, and the pressure plate 201h-6 is movably connected to the sealing sleeve 201f.

[0069] The rotating rod 201h-5 is rotatably connected to the surface of the support plate 201h-4 through a bearing. When the pressure plate 201h-6 is pressed onto the surface of the sealing sleeve 201f, the torsion spring 201h-7 is in a deformed state. The surface of the sealing sleeve 201f is provided with a pressure groove that cooperates with the pressure plate 201h-6. The pressure plate 201h-6 that is moved and pressed into it can be limited by the pressure groove. Even when the sixth gear 201h-8 is disengaged from the tooth 201h-9, under the action of the torsion reset force of the torsion spring 201h-7, the pressure groove can limit the pressure plate 201h-6, so that the pressure plate 201h-6 will not be separated from the sealing sleeve 201f and lose its pressing effect.

[0070] During installation, after the positioning column 201k is inserted into the positioning groove, the sixth gear 201h-8 is inserted into the hole on the turntable 201g-7, and then the turntable 201g-7 is rotated to make the tooth 201h-9 engage and rotate with the sixth gear 201h-8, thereby rotating the rotating rod 201h-5 and the pressure plate 201h-6, as well as the torsion spring 201h-7. Then, when the buckle plate 201g-3 is buckled on the surface of the ring plate 201e, the slider 201h-2 is squeezed and moved, causing the fourth spring 201h-3 to be compressed and the support plate 201h-4 to move, thereby driving the rotating rod 201h-5 and the pressure plate 201h-6 to move, and moving the pressure plate 201h-6 into the pressure groove to press the sealing sleeve 201f.

[0071] The cleaning member 201i includes a square rod 201i-1, a scraper 201i-2, a vertical rod 201i-3, a guide groove 201i-4, a fifth spring 201i-5, a filter screen 201i-6, a rubber ring 201i-7 and a dust cover 201i-8. The square rod 201i-1 is movably connected to the surface of the cover 201d, the scraper 201i-2 is fixedly connected to one end of the square rod 201i-1, the vertical rod 201i-3 is fixedly connected to the other end of the square rod 201i-1, the guide groove 201i-4 ​​is opened at the bottom of the turntable 201g-7, the vertical rod 201i-3 The upper end is inserted into the guide groove 201i-4, the fifth spring 201i-5 is sleeved on the surface of the square rod 201i-1, and the two ends of the fifth spring 201i-5 are respectively fixedly connected to the square rod 201i-1 and the surface of the cover body 201d, the filter screen 201i-6 is sleeved on the surface of the rubber ring 201i-7 and fixedly connected to the inner wall of the cover body 201d, the rubber ring 201i-7 is sleeved on the surface of the piston rod 201c and fixedly connected to the surface of the filter screen 201i-6, and the dust cover 201i-8 is sleeved on the surface of the piston rod 201c and clamped on the surface of the cover body 201d.

[0072] The square rod 201i-1 passes through the cover body 201d and is sealed therebetween. A large gap between the filter screen 201i-6 and the piston rod 201c is avoided by a rubber ring 201i-7. At the same time, the surface of the moving piston rod 201c can be cleaned to a certain extent. The impurities cleaned by the scraper 201i-2 are intercepted by the filter screen 201i-6 to prevent them from entering the cylinder body 201a. The dustproof sleeve 201i-8 plays a dust-proof role and a secondary sealing role. The guide groove 201i-4 ​​is divided into an annular part and a transition part.

[0073] By rotating the turntable 201g-7, when one end of the vertical rod 201i-3 moves in the annular part of the guide groove 201i-4, the vertical rod 201i-3 will not drive the square rod 201i-1 to move so that the scraper 201i-2 contacts the surface of the piston rod 201c. When in the transition part in the guide groove 201i-4, it will drive the square rod 201i-1 to move so that the scraper 201i-2 contacts the surface of the piston rod 201c, and clean the moving surface of the piston rod 201c. When it is rotated again, the scraper 201i-2 will be separated from the surface of the piston rod 201c. The fifth spring 201i-5 generates an elastic force under its compression, which provides power for the resetting of the vertical rod 201i-3, the square rod 201i-1 and the scraper 201i-2.

[0074] The limiting member 201g-4 includes a groove 201g-4-1, a third spring 201g-4-2, a second clamping block 201g-4-3 and a limiting block 201g-4-4. The groove 201g-4-1 is opened on the surface of the cylinder 201a, and the second clamping block 201g-4-3 is slidably connected in the groove 201g-4-1. The two ends of the third spring 201g-4-2 are respectively fixedly connected to the inner wall of the groove 201g-4-1 and the surface of the second clamping block 201g-4-3. The limiting block 201g-4-4 is fixedly connected to the surface of the second clamping block 201g-4-3. The inner wall of the groove 201g-4-1 is provided with a limiting groove matched with the limiting block 201g-4-4. The limiting block 201g-4-4 is slidably connected in the limiting groove, and the second clamping block 201g-4-3 is movably connected to the first clamping block 201g-5.

[0075] One end of the second clamping block 201g-4-3 extends to the inner wall of the through hole, thereby limiting the movable sleeve 201g-1 inserted into the ring plate 201e. The elastic force of the third spring 201g-4-2 provides a reset force for the second clamping block 201g-4-3 after the extrusion movement. The movement of the second clamping block 201g-4-3 is limited and guided by the limiting groove and the limiting block 201g-4-4 to prevent it from separating from the cylinder 201a.

[0076] The lubricating component 201j includes a lubricating oil chamber 201j-1, an oil outlet hole 201j-2, a ball 201j-3, a valve component 201j-4 and a driving component 201j-5. The lubricating oil chamber 201j-1 and the oil outlet hole 201j-2 are both opened in the cover body 201d. The oil outlet hole 201j-2 is connected to the lubricating oil chamber 201j-1. The ball 201j-3 is rotatably connected to the inner wall of the oil outlet hole 201j-2. The valve component 201j-4 is arranged in the oil outlet hole 201j-2. The driving component 201j-5 is arranged on the surface of the cover body 201d. An oil filling pipe is fixedly connected to the surface of the cover body 201d. A sealing cover is provided at one end of the oil filling pipe. The oil filling pipe is connected to the lubricating oil chamber 201j-1.

[0077] The lubricating oil chamber 201j-1 is in the shape of a circular ring, and the movement of the piston rod 201c can drive the ball 201j-3 to rotate, so that the lubricating oil discharged through the valve member 201j-4 is indirectly applied to the surface of the piston rod 201c through the ball 201j-3, thereby lubricating the surface of the piston rod 201c and reducing friction.

[0078] When the fixing part 201g is fixed between the cylinder body 201a and the cover body 201d, it acts on the driving part 201j-5, thereby opening the valve part 201j-4, allowing the lubricating oil to be discharged to lubricate the surface of the piston rod 201c. During disassembly, the fixing part 201g no longer acts on the driving part 201j-5, causing the valve part 201j-4 to be closed, thereby avoiding leakage of lubricating oil after disassembly is completed, which causes waste.

[0079] Example 4 Reference Figures 10 to 18 , which is the fourth embodiment of the present invention, and is based on the first three embodiments.

[0080] Specifically, the fork member 105b includes a fork plate 105b-1, a positioning bolt 105b-2, a first spring 105b-3 and a steel ball 105b-4. The fork plate 105b-1 is sleeved on the surface of the shift rod 105a, and the fork plate 105b-1 is clamped on the surface of the clutch 102d. The positioning bolt 105b-2 is threadedly connected to the surface of the fork plate 105b-1, the first spring 105b-3 and the steel ball 105b-4 are movably connected in the fork plate 105b-1, and the two ends of the first spring 105b-3 are movably connected to the positioning bolt 105b-2 and the surface of the steel ball 105b-4 respectively, and the steel ball 105b-4 is slidably connected to the shift rod 105a.

[0081] The first spring 105b-3 installed in the fork plate 105b-1 is restricted by the positioning bolt 105b-2, and then the steel ball 105b-4 is brought into close contact with the surface of the shift rod 105a under the action of the pressure and deformation of the first spring 105b-3. When the steel ball 105b-4 moves into the shift groove, the fork plate 105b-1 is limited, and then the clutch 102d and the spline sleeve 102e that are driven to move are limited.

[0082] The valve component 201j-4 includes a valve body 201j-4-1, an orifice plate 201j-4-2, a valve stem 201j-4-3, a valve plug 201j-4-4 and a sixth spring 201j-4-5. The valve body 201j-4-1 is fixedly connected to the inner wall of the oil outlet hole 201j-2, the orifice plate 201j-4-2 is fixedly connected to the inner wall of the valve body 201j-4-1, the valve stem 201j-4-3 is slidably connected to the surface of the orifice plate 201j-4-2, the valve plug 201j-4-4 is fixedly connected to one end of the valve stem 201j-4-3, the sixth spring 201j-4-5 is sleeved on the surface of the valve stem 201j-4-3, and the two ends of the sixth spring 201j-4-5 are respectively fixedly connected to the valve plug 201j-4-4 and the surface of the orifice plate 201j-4-2.

[0083] The valve stem 201j-4-3 passes through the orifice plate 201j-4-2 and is slidably connected thereto. One end of the valve plug 201j-4-4 is chamfered, so that when the driving member 201j-5 squeezes it, the valve plug 201j-4-4 can be moved and opened to discharge the lubricating oil in the lubricating oil chamber 201j-1. The sixth spring 201j-4-5 is compressed when the valve plug 201j-4-4 moves and opens, and its elastic force provides power for resetting the valve plug 201j-4-4 and the valve stem 201j-4-3.

[0084] The driving member 201j-5 includes a hole slot 201j-5-1, a pressure rod 201j-5-2, a pressure block 201j-5-3, a push rod 201j-5-4, a seventh spring 201j-5-5 and an eighth spring 201j-5-6. The hole slot 201j-5-1 is opened in the cover body 201d, the pressure rod 201j-5-2 and the push rod 201j-5-4 are both slidably connected to the hole slot 201j-5-1, the pressure block 201j-5-3 is fixedly connected to one end of the pressure rod 201j-5-2, and the seventh spring 201j-5-5 and the eighth spring 201j-5-6 are fixedly connected to the pressure rod 201j-5-2. The two ends of 01j-5-5 are respectively fixedly connected to the surface of the pressure rod 201j-5-2 and the inner wall of the hole groove 201j-5-1, the eighth spring 201j-5-6 is respectively fixedly connected to the surface of the push rod 201j-5-4 and the inner wall of the hole groove 201j-5-1, the surface of the pressure block 201j-5-3 is movably connected to the surface of the buckle plate 201g-3, the surface of the pressure rod 201j-5-2 is movably connected to the surface of the push rod 201j-5-4, and the surface of the push rod 201j-5-4 is movably connected to the surface of the valve plug 201j-4-4.

[0085] The end of the pressure rod 201j-5-2 away from the pressure block 201j-5-3 is chamfered, and both ends of the push rod 201j-5-4 are chamfered to facilitate squeezing the push rod 201j-5-4 to move when the pressure rod 201j-5-2 moves, thereby squeezing the valve plug 201j-4-4 to move and open it when the push rod 201j-5-4 moves. A seal is performed between the push rod 201j-5-4 and the cover body 201d, and the seventh spring 201j-5-5 and the eighth spring 201j-5-6 are compressed as they move with the pressure rod 201j-5-2 and the push rod 201j-5-4. When the buckle plate 201g-3 is separated from the pressure block 201j-5-3, power is provided for the reset of the pressure rod 201j-5-2 and the push rod 201j-5-4.

[0086] When in use, the present invention has two working states. The first working state is good coordination when multiple power outputs are in progress. The engine drives the input shaft 102a to rotate, thereby rotating the clutch 102d and the spline sleeve 102e, and then rotating the spline cylinder 102b and the first gear 102c. The rotation of the first gear 102c rotates the second gear 103b and the third gear 104c, and the rotation of the two second gears 103b drives the rotation of the two first output shafts 103a.

[0087] The first output shaft 103a is connected to the outside world by a flexible shaft transmission technology combined with an adjustable universal joint structure to ensure that the power output by the two oil pumps can be stably transmitted without being restricted by distance and angle. The rotation of the third gear 104c causes the first shaft 104a and the fourth gear 104d to rotate, and then the fifth gear 104e, the first bevel gear 104f and the second shaft 104b to rotate, and then the second bevel gear 104h and the second output shaft 104g to rotate. Through high-precision gear processing and shaft assembly technology, the power output of the shaft is guaranteed to be strong and stable, and hard power output is achieved.

[0088] The second working state is to ensure that the clutch 102d is in a completely disengaged state when the engine is started, reduce the starting torque requirement, and enable the engine to start easily. The hydraulic component 201 drives the connecting plate 202 to rotate the wrench 105d, thereby rotating the shift rod 105c, causing the shift fork plate 105b-1 to move and drive the clutch 102d and the spline sleeve 102e to move, so that the spline sleeve 102e is separated from the spline cylinder 102b.

[0089] The rotation of the input shaft 102a drives the rotation of the clutch 102d and the spline sleeve 102e, but does not drive the rotation of the spline cylinder 102b and the first gear 102c, and thus does not drive the soft power output member 103 and the hard power output member 104 to operate. The clutch 102d is in a completely disengaged state, which reduces the starting torque requirement, enables the engine to be easily started, and improves the overall operating efficiency and reliability of the equipment.

[0090] When disassembling between the cover body 201d and the cylinder body 201a, first remove the connecting plate 202 from the piston rod 201c, then hold the turntable 201g-7 and rotate it at a certain angle to rotate the teeth 201h-9 and the extrusion block 201g-8. The rotation of the teeth 201h-9 slightly drives the sixth gear 201h-8 to rotate and then disengage. Since there is a moving gap between the pressure groove and the pressure plate 201h-6, it will not affect the rotation of the pressure plate 201h-6 with the rotating rod 201h-5 and the sixth gear 201h-8.

[0091] The guide groove 201i-4 ​​squeezes the vertical rod 201i-3 to move as the turntable 201g-7 rotates, which drives the square rod 201i-1 to move so that the scraper 201i-2 contacts the surface of the piston rod 201c, cleans the surface of the moving piston rod 201c, and then rotates to separate the scraper 201i-2 from the surface of the piston rod 201c. The fifth spring 201i-5 generates elastic force under the action of its compression, which provides power for the resetting of the vertical rod 201i-3, the square rod 201i-1 and the scraper 201i-2.

[0092] Then continue to rotate the turntable 201g-7 to make the extrusion block 201g-8 contact and extrude the first block 201g-5, so that the first block 201g-5 can move and disengage from the arc hole, and then make the first block 201g-5 pressurize the second block 201g-4-3 to make it move into the groove body 201h-1, lose the limit on the movable sleeve 201g-1, and then move the movable sleeve 201g-1 away from the ring plate 201e, and then pull and rotate the movable plate 201g-2, so that the buckle plate 201g-3 rotates out of the cover body 201d, the slider 201h-2 and the pressure block 201j-5-3 surface, completing the separation between the cylinder 201a and the cover body 201d.

[0093] During this process, the slider 201h-2 loses its pressure and resets under the action of the fourth spring 201h-3, thereby causing the support plate 201h-4, the rotating rod 201h-5, the sixth gear 201h-8 and the pressure plate 201h-6 to return, causing the pressure plate 201h-6 to separate from the sealing sleeve 201f, and under the action of the torsion spring 201h-7, the rotating rod 201h-5, the pressure plate 201h-6 and the sixth gear 201h-8 rotate and reset, thereby facilitating the disassembly of the sealing sleeve 201f.

[0094] During the process of the buckle plate 201g-3 separating from the pressure block 201j-5-3, the pressure rod 201j-5-2, the push rod 201j-5-4 and the pressure block 201j-5-3 are reset under the action of the seventh spring 201j-5-5 and the eighth spring 201j-5-6, so that the push rod 201j-5-4 separates from the valve plug 201j-4-4, and the valve stem 201j-4-3 and the valve plug 201j-4-4 are reset and closed under the action of the elastic force of the sixth spring 201j-4-5, thereby avoiding the leakage of lubricating oil after disassembly and causing waste.

[0095] The operation steps during installation are the opposite. While the cylinder 201a and the cover 201d are quickly installed, pressure is applied to the installed sealing sleeve 201f to increase the sealing effect, and the lubricating part 201j is opened to lubricate the piston rod 201c during operation, thereby reducing friction and increasing service life. At the same time, the scraper 201i-2 will not contact the piston rod 201c, thereby preventing the piston rod 201c from frequently moving back and forth and causing wear on it by the scraper 201i-2.

[0096] In summary, the power input component 102, the soft power output component 103, the hard power output component 104 and the clutch control component 105 can be organically combined through the gearbox mechanism 100 to achieve accurate cutting off of all power when the engine is not stopped. At the same time, when the engine is started, the starting torque requirement is reduced. Compared with the prior art, the coordination of multiple power outputs is good, and the engine does not need to overcome a large load torque when starting. Through the cooperation between the fixing component 201g and the holding component 201h, the cleaning component 201i and the lubricating component 201j, compared with the prior art, while the hydraulic cylinder can be quickly installed, pressure is applied to the installed sealing sleeve 201f to increase the sealing effect, and the piston rod 201c is lubricated by the lubricating component 201j during operation to avoid clogging of the cylinder during long-term use.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
