Description

Technical Field

[0001] This invention relates to the field of transportation chassis technology, and in particular to a leveling transportation chassis for hilly orchards with adjustable track gauge and center of gravity. Background Technology

[0002] Due to geographical limitations and traditional planting methods, the level of mechanization in orchard transportation is low, with manual handling being the primary method. However, manual handling directly leads to a longer harvest period for fruit, and sometimes the low efficiency of harvesting and handling causes the best picking time to be missed. A few post-harvest transport vehicles use rail or cableway transport, but these have poor mobility and high input costs. In addition, existing small-scale orchard transport chassis lack obstacle-crossing, hill-climbing, and transport capacity, making them unsuitable for transporting in steep orchards. There is an urgent need to accelerate the research process on the mechanization of orchard transportation in hilly and mountainous areas.

[0003] Therefore, in response to the problems of rugged terrain, fragmented plots, steep slopes, large undulations, numerous bends, incomplete road construction, and many obstacles in hilly and mountainous orchards, a leveling and transport chassis for hilly and mountainous orchards with adjustable track gauge and center of gravity was designed. This improves the obstacle-crossing ability, climbing ability, and carrying capacity of the orchard transport chassis, further enhancing the transportation efficiency of hilly and mountainous orchards and promoting the development of orchard transport machinery.

[0035] This invention not only improves the obstacle-crossing capability of the overall transport chassis by symmetrically sliding connecting frames on both sides of the central frame and installing tracked walking units on the connecting frames, thereby driving the central frame and the two connecting frames to move through the tracked walking units, but also provides a track gauge adjustment mechanism on the central frame for the two sliding connecting frames, thereby adjusting the distance between the connecting frames and the two tracked walking units to meet the track gauge adjustment requirements.

[0036] Meanwhile, by setting the box body on the top of the connecting frame and movably connecting the two sides of the box body to the two connecting frames respectively, and driving the leveling mechanism to level one side of the adjacent box body, the box body can be raised and lowered relative to the connecting frame.

[0037] In addition, this patent also has a sliding mechanism on the central frame, which can drive the battery box to slide along the length of the central frame. The weight of the battery box helps to stabilize the center of gravity of the overall transport chassis. Based on the track gauge adjustment by moving the connecting frame along the width of the central frame, the center of gravity is adjusted by moving the battery box along the length of the central frame. This can effectively ensure the stability of the transport chassis by adjusting the center of gravity, thereby improving the transport efficiency in hilly orchards. Attached Figure Description

Detailed Implementation

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] Reference Figures 1-10 This invention provides a leveling and transport chassis for hilly and mountainous orchards with adjustable track gauge and center of gravity, comprising:

[0053] The center frame 1 has connecting frames 2 that slide along both sides in the width direction, and a tracked walking unit 3 is installed at the bottom of the connecting frames 2.

[0054] The track gauge adjustment mechanism is set on the center frame 1. The adjustment end of the track gauge adjustment mechanism is connected to the two connecting frames 2 respectively to adjust the distance between the two track walking units 3.

[0055] Box 5 is arranged at the top of connecting frame 2 and symmetrically distributed on both sides along the central frame 1 and is movably connected to the two connecting frames 2 respectively. The connecting frame 2 is provided with a leveling mechanism 6. The leveling end of the leveling mechanism 6 is connected to one side of the adjacent box 5 so that one side of the box 5 can be raised or lowered relative to the connecting frame 2.

[0056] The battery box 7 is movably arranged on the central frame 1 and forms a center of gravity located in the lower middle part relative to the transport chassis. The central frame 1 is provided with a sliding mechanism 8, and the drive end of the sliding mechanism 8 is connected to the battery box 7 so that the battery box 7 can be moved controllably along the length direction of the central frame 1.

[0057] This invention improves the obstacle-crossing capability of the overall transport chassis by symmetrically sliding connecting frames 2 on both sides of a central frame 1 and mounting tracked walking units 3 on the connecting frames 2. The tracked walking units 3 drive the central frame 1 and the two connecting frames 2 to move. Furthermore, a track gauge adjustment mechanism is provided on the central frame 1 to adjust the distance between the connecting frames 2 and the two tracked walking units 3, meeting track gauge adjustment requirements. Simultaneously, a housing 5 is positioned at the top of the connecting frames 2, and both sides of the housing 5 are movably connected to the two connecting frames 2. A leveling mechanism 6 levels one side of each adjacent housing 5. The drive mechanism enables the lifting and leveling of both sides of the box 5 relative to the connecting frame 2, improving its applicability to rugged roads while ensuring the leveling effect of the box 5. In addition, this patent also provides a sliding mechanism 8 on the central frame 1, which can drive the battery box 7 to slide along the length of the central frame 1. The gravity of the battery box 7 is used to stabilize the center of gravity of the overall transport chassis. Based on the track gauge adjustment by the movement of the connecting frame 2 along the width of the central frame 1, the center of gravity is adjusted by the movement of the battery box 7 along the length of the central frame 1. This can effectively ensure the stability of the transport chassis by adjusting the center of gravity, thereby improving the transport efficiency in hilly orchards.

[0058] Reference Figure 2 Furthermore, the track gauge adjustment mechanism includes:

[0059] At least one pair of hydraulic support units 4 are arranged along the width direction of the central frame 1. Any pair of hydraulic support units 4 are symmetrical with respect to the central frame 1. One side of the hydraulic support unit 4 is connected to the central frame 1, and the other side of the hydraulic support unit 4 is connected to the adjacent connecting frame 2, so that the two connecting frames 2 are close to or far from each other.

[0060] Each hydraulic support unit 4 has at least two support ends connected to the connecting frame 2, and the support ends are distributed along different horizontal heights.

[0061] In this technical solution, at least one pair of hydraulic support units 4 are arranged along the width direction of the central frame 1, thus being coaxially arranged with the sliding direction of the connecting frame 2. The hydraulic support units 4 are symmetrical about the center of the central frame 1, maintaining the structural stability of the transport chassis. Furthermore, at least two support ends of the hydraulic support units 4 are connected to the connecting frame 2. When the connecting frame 2 is hydraulically driven, the hydraulic support units 4 provide multi-point support to the connecting frame 2, which can effectively improve the movement stability of the connecting frame 2. Based on the track walking unit 3 installed on the connecting frame 2, the effect of adjusting the track gauge of the overall transport chassis is further improved.

[0062] Furthermore, the hydraulic support unit 4 includes:

[0063] At least one horizontal hydraulic cylinder 41 is configured such that one end is hinged to the side wall of the center frame 1, and the other end of the horizontal hydraulic cylinder 41 is hinged to the bottom side wall of the adjacent connecting frame 2.

[0064] At least one tilting hydraulic cylinder 42 is configured such that one end is hinged to the center frame 1 and the hinged end of the center frame 1 is at the same horizontal height as the horizontal hydraulic cylinder 41, and the other end of the tilting hydraulic cylinder 42 is hinged to the side wall of the adjacent connecting frame 2 in an upward tilting direction.

[0065] In this technical solution, a hydraulic support unit 4 is formed by at least one horizontal hydraulic cylinder 41 and at least one tilting hydraulic cylinder 42. The hinge ends of the horizontal hydraulic cylinder 41 and the tilting hydraulic cylinder 42 with the center frame 1 are set at the same horizontal height, while the hinge ends of the two with the adjacent connecting frame 2 are distributed at different heights, so as to ensure multi-point stable support for the connecting frame 2.

[0066] In one embodiment of the present invention, only one pair of horizontal hydraulic cylinders 41 and one pair of tilting hydraulic cylinders 42 are centrally symmetrically arranged relative to the central frame 1, and the horizontal hydraulic cylinders 41 and tilting hydraulic cylinders 42 are arranged along the length direction at the front and rear ends of the central frame 1, effectively controlling equipment production costs. Furthermore, combined with... Figure 2 and Figure 10 It can be seen that the horizontal hydraulic cylinders 41 are horizontally distributed when viewed from the main viewpoint, but when viewed from the bottom viewpoint, the horizontal hydraulic cylinders 41 are axially inclined. Similarly, the inclined hydraulic cylinders 42 are inclined when viewed from the main viewpoint, but the axis of the inclined hydraulic cylinders 42 is horizontally distributed in the bottom viewpoint. Therefore, the movement of the connecting frame 2 relative to the central frame 1 can be achieved by only one pair of horizontal hydraulic cylinders 41 and one pair of inclined hydraulic cylinders 42 working together, and the movement stability of the connecting frame 2 can be ensured.

[0067] Furthermore, the tracked traveling unit 3 includes:

[0068] Track 31 is fitted onto drive wheel set 32 ​​and rotates with connecting frame 2 through drive wheel set 32.

[0069] The drive motor 33 is movably arranged on the central frame 1. The central frame 1 is also equipped with a motor adjustment mechanism 34. The adjustment end of the motor adjustment mechanism 34 is connected to the drive motor 33 so that the drive motor 33 can move in the same direction and synchronously with the connecting frame 2.

[0070] The output shaft of the drive motor 33 is connected to the drive wheel of the transmission wheel set 32 ​​via the pulley set 35, and the pulley set 35 is rotatably connected to the connecting frame 2.

[0071] Two drive motors 33 are symmetrically arranged on the central frame 1. The drive motors 33 drive the transmission wheel set 32 ​​through the pulley set 35. The transmission wheel set 32 ​​enables the track 31 to rotate and engage with the connecting frame 2, thus satisfying the driving function of the transport chassis. At the same time, the motor pitch adjustment mechanism 34 set on the central frame 1 is connected to the drive motors 33, so that the drive motors 33 can move synchronously and in the same direction as the connecting frame 2. When the track gauge of the connecting frame 2 is adjusted, the drive motors 33 are adjusted synchronously to ensure the driving connection effect between the drive motors 33, the pulley set 35 and the transmission wheel set 32, and to ensure that the track 31 can move normally.

[0072] It is understandable that by transferring the transmission wheel set 32 ​​to the side of the connecting frame 2 away from the center frame 1, and supporting the track 31 through the transmission wheel set 32, a tracked walking unit 3 that rotates cyclically on the connecting frame 2 is formed. The output shaft of the drive motor 33 is fixed to any one of the pulleys in the pulley set 35, and the transmission belt forms a driving effect on the remaining pulleys in the pulley set 35. Under the output action of the pulleys, the drive wheel in the transmission wheel set 32 ​​is driven to rotate, which satisfies the driving effect on the track 31 and improves the obstacle crossing ability of the transport chassis.

[0073] Furthermore, the motor pitch adjustment mechanism 34 includes:

[0074] An adjustable pitch motor 341 is fixedly connected to the center frame 1. An adjustable pitch screw 342 is fixedly connected to the output shaft of the adjustable pitch motor 341. The adjustable pitch screw 342 is arranged along the length direction of the center frame 1, and a slider 343 is threaded on the adjustable pitch screw 342. One end of an adjustable pitch connecting rod 345 is hinged to each side of the slider 343. The other end of the adjustable pitch connecting rod 345 is hinged to an adjustable pitch plate 346. The adjustable pitch plate 346 slides on the center frame 1 along the width direction of the center frame 1. A drive motor 33 is fixedly connected to the top surface of the adjustable pitch plate 346.

[0075] The fixed shaft 347 is fixed to the center frame 1 by the fixed piece 348. The slider 343 is sleeved on the fixed shaft 347 on the side away from the adjusting screw 342. The slider 343 slides with the fixed shaft 347. The fixed shaft 347 and the adjusting screw 342 are distributed parallel to each other along the vertical plane.

[0076] The adjustable screw 342 is driven to rotate by the adjustable motor 341. The adjustable screw 342 is rotatably connected to the center frame 1 through the bearing. The slider 343 is limited by the fixed shaft 347 and the fixed plate 348. As the adjustable screw 342 rotates, the slider 343 slides along the axis of the adjustable screw 342. By pressing the two adjustable connecting rods 345, the adjustable plate 346 is limited and slidably connected to the top surface of the center frame 1. The adjustable plate 346 drives the drive motor 33 to slide along the width direction of the center frame 1, thereby realizing the pitch adjustment function of the drive motor 33.

[0077] Furthermore, the leveling mechanism 6 includes:

[0078] The base 61 is mounted on top of the two connecting frames 2, and the box 5 is fixed to the top surface of the base 61.

[0079] At least one pair of balancing hydraulic cylinders 62 are fixedly connected to both sides of the base 61 along the same axial direction. The output shaft of the balancing hydraulic cylinder 62 is hinged to a first hinge seat 63. The two first hinge seats 63 arranged opposite to each other are distributed along the width direction of the central frame 1.

[0080] A pair of supporting hydraulic cylinders 65 are arranged on both sides of the first hinge seat 63 along the length direction of the central frame 1. The bottom of the hinge seat is fixed with a second hinge seat 64. One end of the supporting hydraulic cylinder 65 is hinged to the second hinge seat 64, and the other end of the supporting hydraulic cylinder 65 is hinged to the top surface of the adjacent connecting frame 2.

[0081] Reference Figure 8 By fixing a hinge shaft to the top surface of the connecting frame 2, a pair of supporting hydraulic cylinders 65 are staggered and hinged relative to each other along the length direction of the central frame 1 on the connecting frame 2. The adjacent ends of the pair of supporting hydraulic cylinders 65 are respectively hinged to two second hinge seats 64. By staggering and fixing the two second hinge seats 64 to the bottom end of the first hinge seat 63, the pair of supporting hydraulic cylinders 65 can cooperate to adjust the first hinge seat 63. At the same time, one end of the balancing hydraulic cylinder 62 is hinged to the first hinge seat 63, and the other end of the balancing hydraulic cylinder 62 is fixed to the bottom end of the base 61. The balancing hydraulic cylinder 62 is arranged along the width direction of the central frame 1. The pair of balancing hydraulic cylinders 62 are coaxially fixed, thereby driving the base 61 to move horizontally relative to the central frame 1. Based on the box body 5 fixed to the top surface of the base 61, the leveling effect of the box body 5 structure is achieved.

[0082] Based on this, a pair of coaxially fixed balance hydraulic cylinders 62 can adjust the distance between the two first hinge seats 63. As the connecting frame 2 moves relative to the center frame 1, the balance hydraulic cylinders 62 extend and retract accordingly, ensuring that the box body 5 is still leveled after the track gauge is adjusted.

[0083] Furthermore, when there is a pair of balancing hydraulic cylinders 62, the balancing hydraulic cylinders 62 are located on the central axis of the base 61. When there is more than one pair of balancing hydraulic cylinders 62, the different pairs of balancing hydraulic cylinders 62 are symmetrically distributed along the central axis of the base 61.

[0084] In this technical solution, in order to control the production cost of the equipment, a pair of balancing hydraulic cylinders 62 are set along the central axis of the base 61 to ensure the stability of the first hinge seat 63 during the leveling process. When multiple pairs of balancing hydraulic cylinders 62 are set, by symmetrically arranging them along the central axis of the base 61, the leveling effect of the base 61 can be ensured, and the support stability of the base 61 and the box 5 can be effectively increased.

[0085] Reference Figures 6-7 Furthermore, the sliding mechanism 8 includes:

[0086] The slide rail 81 is fixedly connected to the center frame 1, and the battery box 7 is slidably connected to the slide rail 81.

[0087] The sliding seat 82 is slidably mounted on the central frame 1 along the length of the central frame 1, and the battery box 7 is fixedly connected to the sliding seat 82.

[0088] The rotating motor 83 is fixedly connected in the groove of the center frame 1, and the output shaft of the rotating motor 83 is fixedly connected to the sliding screw 84. The sliding screw 84 is parallel to the slide rail 81, and the sliding seat 82 is threaded on the sliding screw 84. The sliding seat 82 is slidably connected in the groove.

[0089] The rotating motor 83 drives the sliding screw 84 to rotate, and the sliding screw 84 drives the sliding seat 82 to slide along the groove. During the process, the sliding seat 82 drives the battery box 7 to move along the length of the central frame 1, thereby adjusting the center of gravity of the transport chassis. Furthermore, the slide rail 81 fixed on the central frame 1 is used to limit the sliding contact with the battery box 7, ensuring the stability of the battery box 7 during movement.

[0090] Furthermore, the connecting frame 2 is nested on one side of the central frame 1 and slides with the central frame 1. One end of the connecting frame 2 extends into a platform in a vertically upward direction. This platform is used to support the box 5, and the two platforms are slidably connected by a connecting sleeve 9, which is a telescopic linkage structure.

[0091] Reference Figure 1 It can be seen that the bottom of the two connecting frames 2 are nested and slidably connected to the opposite sides of the central frame 1, and the top of the connecting frame 2 is a platform support structure used to support and fix one side of the box 5. At the same time, the two platforms located at the top are slidably connected by the connecting sleeve 9, which improves the structural stability of the two connecting frames 2 and also takes into account the function of adjusting the track gauge of the connecting frame 2 relative to the central frame 1.

[0092] Furthermore, the central frame 1 is a vertical multi-layer structure, and a receiving cavity that runs through both sides is provided in the center of the central frame 1. The drive motor 33 is movably arranged in the receiving cavity, and the battery box 7 is movably arranged at the top of the central frame 1.

[0093] By utilizing the multi-layer structure of the central frame 1, a cavity is formed to accommodate the drive motor 33. At the same time, it can accommodate the battery box 7 set on the central frame 1, so that the adjustable motor 341 drives the slider 343 to move the adjustable plate 346 and the rotating motor 83 drives the sliding seat 82 to slide the battery box 7, thereby meeting the needs of adjusting the pitch of the drive motor 33 and adjusting the center of gravity of the battery box 7.

[0094] The working principle of this invention, a leveling and transport chassis for hilly and mountainous orchards with adjustable track gauge and center of gravity:

[0095] When the track gauge needs to be adjusted, the horizontal hydraulic cylinder 41 and the tilting hydraulic cylinder 42 extend and retract to move the connecting frame 2 relative to the center frame 1. At the same time, the adjusting motor 341 rotates the adjusting screw 342 to move the slider 343. The slider 343 pushes and pulls the adjusting linkage 345 to move the adjusting plate 346, so as to realize the synchronous and co-directional movement of the drive motor 33 and the connecting frame 2, ensuring the driving effect of the track 31 and realizing the track gauge adjustment of the transport chassis. The connecting sleeve 9 and the balancing hydraulic cylinder 62 are used to improve the adjustment stability of the connecting frame 2 and ensure that the leveling mechanism 6 can effectively level the box 5 after the track gauge is adjusted.

[0096] When leveling the housing 5 is required, a pair of supporting hydraulic cylinders 65 are staggered and hinged relative to each other along the length of the central frame 1 on the connecting frame 2 by fixing a hinge shaft to the top surface of the connecting frame 2. The adjacent ends of the pair of supporting hydraulic cylinders 65 are respectively hinged to two second hinge seats 64. By staggering and fixing the two second hinge seats 64 to the bottom end of the first hinge seat 63, the pair of supporting hydraulic cylinders 65 can cooperate to adjust the first hinge seat 63. At the same time, one end of the balancing hydraulic cylinder 62 is hinged to the first hinge seat 63, and the other end of the balancing hydraulic cylinder 62 is fixed to the bottom end of the base 61. The balancing hydraulic cylinder 62 is arranged along the width direction of the central frame 1. The pair of balancing hydraulic cylinders 62 are coaxially fixed, thereby driving the base 61 to move horizontally relative to the central frame 1. Based on the housing 5 being fixed to the top surface of the base 61, the leveling effect of the housing 5 structure is achieved.

[0097] Finally, the sliding screw 84 is driven to rotate by the rotating motor 83. The sliding screw 84 drives the sliding seat 82 to slide along the groove. During the process, the sliding seat 82 drives the battery box 7 to move along the length of the central frame 1, thereby adjusting the center of gravity of the transport chassis. The slide rail 81 fixed on the central frame 1 is used to limit the sliding contact with the battery box 7, ensuring the stability of the battery box 7 during movement.
