Description

Full-frame high-horsepower hybrid tractor Technical Field

[0001] This invention relates to the field of hybrid tractor technology, specifically to a full-frame high-horsepower hybrid tractor. Background Technology

[0002] With the continuous improvement of the automation level of mechanical equipment, high-horsepower hybrid power equipment is increasingly widely used in large-scale operation scenarios. Hybrid power equipment, with its core advantages of energy efficiency, high performance, and stable power output, is gradually replacing traditional pure fuel-powered equipment and becoming the mainstream operating equipment. However, the rear suspension power connection mechanism of existing high-horsepower hybrid power equipment still has significant technical shortcomings in complex operation scenarios and harsh environmental conditions, making it difficult to achieve efficient adaptation. Specific problems are as follows: Firstly, the rear suspension power connection mechanism of current high-horsepower hybrid power equipment mostly adopts a fixed structure design. This type of mechanism relies mainly on a disassembly-type connection method to install and fix the power output component, that is, the power output component is rigidly connected to the suspension frame on the rear side of the equipment using bolts and other fasteners. When it is necessary to adjust the operating parameters of the power output component, only a single-dimensional depth adjustment can be achieved through the hydraulic drive mechanism; however, for critical adjustments such as suspension distance and operating angle, the power output component must first be completely disassembled, and then the adjustment frame must be pulled by multiple people working together or with the help of external traction equipment. After adjustment to the target position, the disassembly-type fixing installation must be performed again. This adjustment method is not only extremely inflexible, but also limited by the weight of the power output components and suspension mechanism. The entire disassembly, adjustment, and reassembly process requires a significant amount of manpower, severely reducing the equipment's operational efficiency and work continuity. On the other hand, hybrid power equipment, due to its hybrid drive architecture, needs to simultaneously carry core components such as battery packs, drive motors, and engines, resulting in an overall weight far greater than traditional pure fuel-powered equipment. In complex working environments, especially in muddy, low-lying, or other easily entangled areas, the equipment's rear drive wheels are prone to getting stuck in the medium and are difficult to extricate themselves. Currently, the mainstream extrication methods mainly rely on external towing equipment for dragging, or manually placing debris or hard blocks under the drive wheels to increase friction and assist the equipment in getting out of trouble. However, in complex outdoor working scenarios, auxiliary materials such as blocks are often not readily available, making extrication operations not only laborious and time-consuming, but also posing safety hazards due to personnel coming into close contact with the equipment's drive components, further affecting operational safety and overall work progress.

[0003] Based on this, the present invention provides a full-frame high-horsepower hybrid tractor to solve the above problems. Summary of the Invention

[0004] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a full-frame high-horsepower hybrid tractor. The present invention has an ingenious structure and focuses on practicality, effectively solving the technical problems of low adjustment efficiency and laborious operation when getting out of a slump.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a full-frame high-horsepower hybrid tractor, including a high-horsepower tractor, a rear transmission output shaft and a side suspension frame at the rear of the high-horsepower tractor, an extension plate mounted on the surface of the side suspension frame, two rear fixing plates fixedly mounted on the rear side of the high-horsepower tractor, each rear fixing plate having an adjustment groove, each adjustment groove having a mounting sleeve slidably connected to a mounting sleeve, the same mounting pin being sleeved in the two mounting sleeves, a locking sleeve being threaded onto the surface of the mounting pin, a connecting sleeve being sleeved on the surface of the mounting pin, and an upper suspension tie rod being fixedly mounted on one end of the connecting sleeve.

[0006] Preferably, the mounting sleeve is fixed with an adjusting rod, and the adjusting rod is fitted with a sliding adjusting rail.

[0007] Preferably, an adjusting rod is fixedly installed on the inner side of each of the two rear fixing plates, and an adjusting sleeve is slidably connected to the surface of each of the two adjusting rods. The same adjusting rail is fixedly installed between the two adjusting sleeves.

[0008] Preferably, one of the rear fixing plates has a threaded slot on its surface, and an adjusting bolt is threaded into the threaded slot, with one end of the adjusting bolt rotatably connected to the adjusting rail.

[0009] Preferably, a rotating frame is rotatably connected below the high-horsepower tractor, and a support pad is slidably connected inside the rotating frame.

[0010] Preferably, a lower support rail is fixedly installed below the high-horsepower tractor, and a rotating telescopic rod that slides on the lower support rail is rotatably connected below the high-horsepower tractor.

[0011] Preferably, a sliding rod is fixedly installed on the surface of the rotating telescopic rod, the sliding rod is slidably connected in the lower support rail, and a return spring is fixedly installed between the lower support rail and the sliding rod.

[0012] The present invention has the following technical advantages.

[0013] 1. This invention uses an adjusting bolt to drive the adjusting rail and adjusting rod in linkage. Operators can easily adjust the angle of the instrument rack with the help of external tools, without the need for complicated equipment, reducing labor intensity, simplifying the disassembly and assembly of instruments and the angle adjustment steps, shortening the preparation time for operation, and improving the efficiency of adjustment operation.

[0014] 2. This invention, equipped with a rotating frame and support pad, allows the arc-shaped support pad to be driven by an electric push rod to fit against the lower side of the rear drive wheel. The anti-slip grooves and conical end face design on the surface of the support pad increase the friction between the rear drive wheel and the ground, helping the tractor to autonomously detach from the silt without the need for external traction equipment. At the same time, the entire operation can be controlled by the controller to operate the electric push rod to complete the unfolding and repositioning of the support pad, without the need to get off the vehicle, reducing the need for personnel to approach, and improving the efficiency and safety of detachment.

[0015] 3. This invention is based on practical applications. The structure it adopts is simple and ingenious. It can achieve good technical results without the need for a complex structure, meet customer needs, has good market prospects, and is highly practical. Attached Figure Description

[0023] Other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to Figures 1 to 6. All content mentioned in the following embodiments is with reference to the accompanying drawings.

[0024] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0025] The present invention is a full-frame high-horsepower hybrid tractor, including a high-horsepower tractor 1, a rear transmission output shaft 25 and a side suspension frame 8 at the rear of the high-horsepower tractor 1. The side suspension frame 8 can drive the rear-mounted machinery to lift. The end face of the side suspension frame 8 is provided with a hook for connection. An extension plate 9 is installed on the surface of the side suspension frame 8. The extension plate 9 is composed of a long strip of plate and a pin that can match the hook welded on the inner side.

[0026] Two symmetrically distributed rear mounting plates 10 are fixedly installed on the rear side of the high-horsepower tractor 1. Each rear mounting plate 10 has an adjustment groove 11 with semi-circular ends. Each adjustment groove 11 is slidably connected to a mounting sleeve 21. The same mounting pin 22 is fitted inside the two mounting sleeves 21. A locking sleeve 23 is threadedly connected to the surface of the mounting pin 22 near one end. The mounting pin 22 is composed of a metal circular plate fixed at one end, a threaded groove near the other end, and a smooth rod in the middle. The same connecting sleeve 24, located in the middle of the two mounting sleeves 21, is fitted onto the surface of the mounting pin 22. An upper suspension tie rod 7 is fixedly installed at one end of the connecting sleeve 24. The upper suspension tie rod 7, together with the side suspension frame 8, achieves three-point suspension support, improving suspension stability.

[0027] The same lifting frame 20 is fixedly installed on the surface of the two mounting sleeves 21. The lifting frame 20 is a U-shaped metal frame, and an adjusting rod 19 is fixedly installed on one side of the lifting frame 20.

[0028] Adjustable fixing rods 14 are fixedly installed on the inner side of both rear fixing plates 10. Adjustable sleeves 17 are slidably connected to the surfaces of both adjustable fixing rods 14. The same adjusting rail 18 is fixedly installed between the two adjusting sleeves 17. The adjusting rail 18 is inclined and has semi-circular ends. The adjusting rod 19 slides inside the adjusting rail 18.

[0029] One of the rear fixing plates 10 has a through threaded slot 12 on its surface. An adjusting bolt 13 is threaded into the slot 12. The adjusting bolt 13 is an internal hexagonal bolt, and one end of the adjusting bolt 13 is rotatably connected to the adjusting rail 18.

[0030] Taking an instrument as an example, an instrument frame 4 is fixedly installed on one side of the extension plate 9. The upper suspension rod 7 is rotatably connected to the two sides of the surface near the end face, and the connecting frame 5 is fixedly installed on the instrument frame 4. The instrument frame 4 is a metal frame composed of multiple cuboid metal frames connected by welding or threading. Multiple evenly distributed instrument blades 6 are fixedly installed below the instrument frame 4. The instrument blade 6 is composed of an arc plate connected to the lower part of the metal frame and a conical blade with an adjustable extension length.

[0031] In this embodiment, before operation, the connecting frame 5 can be attached to the side suspension frame 8 behind the high-horsepower tractor 1 with the help of the extension plate 9. Then, the connecting sleeve 24 is placed roughly between the two adjustment slots 11. After the connecting sleeve 24 is placed, the mounting pin 22 is taken out and inserted into the mounting sleeve 21 and the connecting sleeve 24 respectively. After the mounting pin 22 is inserted, the mounting pin 22 is locked with the locking sleeve 23 to realize the connection between the high-horsepower tractor 1 and the equipment frame 4.

[0032] After connecting the equipment, the angle of the equipment can be increased depending on the farmland environment, specifically the hardness of the ground. When the ground is hard, the angle of the equipment needs to be increased for better results, while the opposite is true when the ground is soft. By using external tools to turn the adjusting bolt 13, the adjusting rail 18 is moved. The adjusting rail 18 first pushes the adjusting rod 19 to move and rise and fall. The rising and falling of the adjusting rod 19 drives the lifting frame 20, the mounting pin 22, and the connecting sleeve 24 to rise and fall, thereby adjusting the angle of the upper suspension rod 7, and thus adjusting the angle of the equipment.

[0033] As an example, two symmetrically distributed front control wheels 2 and two symmetrically distributed rear drive wheels 3 are respectively installed under the high-horsepower tractor 1. The front control wheels 2 are used for steering, and the rear drive wheels 3 are used for driving. A rotating frame 26 is rotatably connected under the high-horsepower tractor 1 with the center of the rear drive wheels 3 as the center. The rotating frame 26 is an arc-shaped metal frame that runs through both sides. Two symmetrically distributed support pads 16 that can contact the rear drive wheels 3 are slidably connected inside the rotating frame 26. The support pads 16 are arc-shaped plates with anti-slip grooves on the upper surface. The sides of the support pads 16 are conical, which makes it easy for the support pads 16 to pass through the silt and be placed under the rear drive wheels 3.

[0034] Two symmetrically distributed electric push rods 35 are fixedly installed above the rotating frame 26. The electric push rods 35 are connected to the power supply and the controller. The output ends of the two electric push rods 35 are fixedly installed with transmission plates 36. The transmission plates 36 are bent metal plates. The two transmission plates 36 are respectively fixed above the two support pads 16.

[0035] Two symmetrically distributed support slots 15 are provided above the rotating frame 26, and two transmission plates 36 are slidably connected in the two different support slots 15 respectively.

[0036] Four symmetrically distributed lower fixing blocks 27 are fixedly installed below the high-horsepower tractor 1. The lower fixing blocks 27 are rectangular metal blocks. The same lower support rail 30 is fixedly installed below every two lower fixing blocks 27. The lower support rail 30 is an arc-shaped metal rail, and the center of the lower support rail 30 is the same as the center of the rear drive wheel 3. A lower adjusting block 28 is fixedly installed below the high-horsepower tractor 1. A rotating telescopic rod 29 is rotatably connected inside the lower adjusting block 28. The rotating telescopic rod 29 is composed of a cylinder and a rod. Two sliding rods 32 are fixedly installed on the surface of the rotating telescopic rod 29 and are slidably connected in two different lower support rails 30. The sliding rods 32 are fixedly installed on the surface of the rotating telescopic rod 29. A return spring 31 is fixedly installed between the two lower support rails 30 and the two sliding rods 32. The return spring 31 continuously provides elastic tension to the sliding rods 32.

[0037] An extension rod 33 is fixedly installed on the lower end face of the rotating telescopic rod 29. A connecting fixing plate 34 is rotatably installed on the extension rod 33 above the rotating frame 26. A return torsion spring is fixedly installed between the extension rod 33 and the connecting fixing plate 34.

[0038] In this embodiment, when the high-horsepower tractor 1 travels through muddy fields, the rear drive wheels 3 are extremely prone to getting stuck in the mud because hybrid tractors are generally heavier than gasoline tractors. When the rear drive wheels 3 get stuck, the operation of the rear drive wheels 3 is stopped to prevent them from getting stuck further. By controlling the electric push rod 35, the two support pads 16 are gradually moved closer to the front and lower side of the two rear drive wheels 3. After the support pads 16 are fully extended, the rear drive wheels 3 are driven to work again. The rear drive wheels 3 will roll over the upper surface of the support pads 16, increasing the friction and allowing the rear drive wheels 3 and the high-horsepower tractor 1 to get out of the stuck position. During the process of getting out, the support... The pad 16 is pressed down by the rear drive wheel 3, and as the rear drive wheel 3 moves forward, the high-horsepower tractor 1 follows. The support pad 16 cannot move forward because it is pressed down by the rear drive wheel 3, so the rotating telescopic rod 29 rotates relative to the support pad 16, and the sliding rod 32 rotates relative to the lower support rail 30. This continues until the rear drive wheel 3 is disengaged from the surface of the support pad 16, that is, when it is out of the trapped position, the electric push rod 35 is controlled to work, which drives the two support pads 16 to reset. During the reset process, with the help of the tension of the reset spring 31, the sliding rod 32, the rotating frame 26 and the support pad 16 are reset to the position in front of the rear drive wheel 3, thus achieving the effect of safely getting out of the trap without getting off the vehicle.

[0039] It should be noted that since the rear drive wheel 3 may be stuck to different depths, if the initial depth of the stuck position makes it impossible for the support pad 16 to be placed exactly in front of the rear drive wheel 3 and about to be pressed down, then it is necessary to manually push the support pad 16 with a tool to slide it closer to the rear drive wheel 3 until the support pad 16 is placed exactly under the front of the rear drive wheel 3.

[0040] Working principle: First, the extension plate 9 is matched with the hook of the side suspension frame 8 via a pin. The connecting sleeve 24 is placed between the adjustment slots 11 of the rear fixing plate 10. The mounting pin 22 is inserted through the mounting sleeve 21 and the connecting sleeve 24. The locking sleeve 23 locks the device to the high-horsepower tractor 1. The upper suspension tie rod 7 and the side suspension frame 8 form a three-point suspension support to improve stability. Then, the adjusting bolt 13 is rotated to move the adjusting rail 18, pushing the adjusting rod 19 and the lifting frame 20 to rise and fall. The angle of the upper suspension tie rod 7 is adjusted by the connecting sleeve 24, thereby changing the working angle of the device frame 4 and the device blade 6. The front control wheel 2 is responsible for steering, and the rear drive wheel 3 provides power, working together with the tool cutter head 6 to complete the operation. When the rear drive wheel 3 gets stuck in the mud, the operation of the rear drive wheel 3 is stopped first, and the electric push rod 35 is started to drive the support pad 16 to unfold to the side and below the rear drive wheel 3. The rear drive wheel 3 is started, and the rear drive wheel 3 crushes the anti-slip groove on the support pad 16 to increase friction and get out of trouble. After getting out of trouble, the electric push rod 35 is reset, and the reset tension spring 31 and reset torsion spring drive the rotating frame 26, sliding rod 32 and other components to be retracted to the initial position, realizing the integrated structure. It does not require a lot of manual labor or external traction, and there is no need to get off the vehicle, making the operation safer.

[0041] It should also be noted that the detachment method in this invention is applicable to most detachment environments during normal operation, but not to detachment in all environments or under all conditions.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
