Description

Technical Field

[0001] This invention relates to the field of maintenance machinery technology for orchard weeding and rotary tillage, and in particular to an orchard operation machine with optional rotary tillage and weeding functions. Background Technology

[0002] In orchard management, rotary tillage and weeding are two frequent and crucial operations. Existing technologies, such as the offset rotary tiller for orchards described in patent CN 201054872Y, address the challenges of working in the root zone of fruit trees. This machine, through its A-frame suspension and horizontal connecting frame, flexibly connects to the tractor, achieving an offset arrangement of the rotary tiller blades. This allows it to reach deep under low-lying tree canopies for integrated loosening, weeding, and fertilization, significantly reducing manual labor. However, such equipment is limited in function, only capable of rotary tillage. When switching to weeding or other operations, the entire machine must be replaced or complex mechanical modifications must be made, which is not only time-consuming and labor-intensive but also increases the user's equipment purchase and maintenance costs. Furthermore, its fixed blade shaft angle limits its adaptability to complex terrain or hidden obstacles, easily leading to uneven tillage or component damage.

[0003] The "rotary tiller obstacle avoidance device" in patent CN 203575027 U achieves rapid response when encountering obstacles by linking a detection rod, pull line, rotating frame, and control valve, in conjunction with a sway cylinder driving the cutter head to retract inward to avoid obstacles. While this design improves operational safety, its core remains focused on obstacle avoidance optimization for a single function (rotary tilling), failing to address the fundamental need for equipment function expansion and rapid conversion. Furthermore, the device's transmission and drive structure (such as control valves, cylinders, and connecting rods) is integrated into the main frame; if it needs to be replaced with a weeding function module, it also faces the problems of cumbersome overall disassembly and assembly and poor component compatibility.

[0004] Therefore, the current orchard machinery industry urgently needs a type of operating equipment that can be easily converted, while retaining the advantages of offset operation and intelligent obstacle avoidance, to achieve rapid modular switching of core functions such as rotary tillage and weeding, thereby reducing the overall cost for users and improving the operating efficiency and adaptability in complex orchard environments. Summary of the Invention

[0005] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides an orchard operation machine with optional rotary tillage and mowing functions that can be easily replaced with a weeding module and a rotary tillage module.

[0006] Technical solution: To achieve the above objectives, the orchard operation machine of the present invention, which has optional rotary tillage and mowing functions, has a traction frame and an adjustment frame arranged at the front and rear, and the two are connected by a lateral adjustment mechanism;

[0007] The traction frame is a horizontally placed strip structure, with a rotating base rotatably mounted at one end. A first hydraulic cylinder connects the rotating base and the adjusting frame to control their relative rotation. A functional module is mounted on the rotating base; this module can be either a rotary tillage module or a weeding module. The rotary tillage module and the weeding module each include a housing, a blade shaft, and a blade assembly. Specifically, the rotary tillage module includes a first housing, a first blade shaft, and a rotary tillage blade assembly; the weeding module includes a second housing, a second blade shaft, and a weeding blade assembly. A drive mechanism is installed inside the adjusting frame. This drive mechanism includes a hydraulic motor, a drive shaft, a universal joint, and a transition shaft, all connected in sequence. The hydraulic motor and the universal joint are located at opposite ends of the adjusting frame.

[0008] The end plate of the rotating seat has an upward-opening U-shaped groove and two sliding grooves on both sides of the U-shaped groove; the cover has two embedding parts that can be embedded in the sliding grooves; after the two embedding parts are embedded in the two sliding grooves on both sides of the U-shaped groove, the end of the cutter shaft is placed in the U-shaped groove; the sliding direction of the embedding parts when they are embedded in the sliding grooves is perpendicular to the axial direction of the cutter shaft.

[0009] The drive shaft includes a first shaft portion with a defined position and a second shaft portion that can slide relative to the first shaft portion, and also includes a spring acting on the second shaft portion, the spring causing the drive shaft as a whole to have an elongation tendency; the adjustment frame is equipped with a handle that can drive the second shaft portion to slide;

[0010] A retaining seat is slidably mounted on the rotating base, and the transition shaft is connected to the retaining seat. The direction in which the retaining seat slides relative to the rotating base is parallel to the axial direction of the cutter shaft. The transition shaft can dock with the cutter shaft, and both have docking structures.

[0011] In use, when a functional module needs to be replaced, first turn the handle to slide the second shaft relative to the first shaft, shortening the entire drive shaft. This allows the transition shaft to slide relative to the rotating seat, disengaging the cutter shaft of the current functional module from the transition shaft. Then, secure the handle with a pin to keep the cutter shaft and transition shaft in the disengaged state. Next, slide the cover upwards, causing the insert of the cover to slide out of the corresponding groove. This allows for quick disassembly of the current functional module. When installing a new functional module, insert the insert of the cover of the new functional module into the groove, then pull the handle back to extend the entire drive shaft. The mating structure at the end of the transition shaft abuts against the mating structure on the cutter shaft. Then, manually rotate the cutter shaft; under the thrust of the spring, ensure that the mating structures of the cutter shaft and transition shaft engage. Furthermore, both the cover and the rotating seat have positioning holes. After docking, the positioning holes on both are aligned, and the cover and rotating seat are fixed by hand-turning the knob.

[0012] Furthermore, the end of the housing connected to the rotating seat has an annular groove structure arranged around the end of the cutter shaft, which can engage with the edge of the U-shaped groove. This structure, with its dual engagement of the insert and the groove, and the annular groove structure engaging with the edge of the U-shaped groove, improves the structural stability and reliability after installation. A bearing seat supporting the cutter shaft is mounted at the end of the rotating seat, and the annular groove structure is arranged around the bearing seat.

[0013] Furthermore, the rotating seat has two side plates perpendicular to the end plate; each of the two side plates has a guide rail installed on its inner side, and the two sides of the retaining seat slide relative to the corresponding guide rails. The two guide rails are rotatably connected relative to the adjusting frame.

[0014] Furthermore, the docking structure on the cutter shaft includes a first docking seat, which has a main docking hole and a plurality of square grooves arranged around the main docking hole, the square grooves communicating with the main docking hole;

[0015] The docking mechanism on the transition shaft includes a second docking seat, which has a central shaft portion and outward protrusions arranged around the central shaft portion in a number consistent with the number of square slots; each outward protrusion has a roller at its front end, and the roller has a portion that protrudes beyond the end of the central shaft portion.

[0016] Using the above docking structure, during docking operations, the first docking seat and the second docking seat are relatively close. If the docking is successful, the roller directly enters the corresponding square groove to guide the central shaft into the main docking hole. If the docking is not successful, the roller abuts against the end face of the first docking seat. When the user manually rotates the cutter shaft, the roller rolls on the end face until the rollers enter the square grooves respectively. Under the thrust of the spring, the central shaft enters the main docking hole.

[0017] Furthermore, the adjusting frame is a square tube structure with a mounting base fixed inside; the mounting base has a first bearing seat with a fixed position, and a second bearing seat and a guide slider for guiding the second bearing seat are also slidably mounted thereon; the first shaft and the second shaft are respectively mounted on the first bearing seat and the second bearing seat. The hydraulic motor is also mounted on the mounting base, and the hydraulic motor is connected to the first shaft via a coupling.

[0018] Furthermore, the second shaft has a pin, the handle has a slot for inserting the pin, and the handle is hinged to the adjustment frame, with a portion extending beyond the adjustment frame for easy operation.

[0019] Furthermore, the lateral adjustment mechanism includes a plurality of connecting frames connected between the traction frame and the adjustment frame, and also includes an adjusting cylinder and a first reset spring for adjusting the relative angle between the connecting frames and the traction frame;

[0020] The regulating cylinder is connected to the stroke valve; the lateral adjusting mechanism also includes a rod that can rotate relative to the cover and a second return spring acting on the rod, the rod acting on the stroke valve via a pull wire.

[0021] During operation, the rod extends beyond the outer end of the casing. When the end of the rod encounters an obstacle, the rod rotates, which acts on the stroke valve to relieve pressure on the regulating cylinder. The first reset spring pulls the connecting frame to move the regulating frame laterally to avoid the obstacle. After bypassing the obstacle, the rod resets, the stroke valve is no longer subjected to external force, the pressure in the regulating cylinder is restored, and the regulating frame is driven to reset.

[0022] Beneficial effects: The orchard machine of the present invention, which has optional rotary tillage and mowing functions, has the following beneficial effects:

[0023] (1) In this invention, the installation and transmission structures of the orchard machine with rotary tillage and mowing functions have been improved, realizing the modularization of the rotary tillage module and the mowing module. Through the coordinated cooperation of the transmission structure and the installation structure, the functional modules can be quickly disassembled and replaced, greatly improving the convenience of operation and the replacement efficiency. By quickly replacing the functional modules, it is not necessary to purchase a complete set of rotary tillers and mowers separately, which can reduce the overall mechanical cost of orchard maintenance.

[0024] (2) The drive shaft, the first bearing housing, the second bearing housing and the hydraulic motor are all mounted on the mounting base. After the above structures are assembled, they are installed in the adjustment frame, which can improve the assembly efficiency and protect the drive mechanism to prevent impurities from winding and causing failure.

[0025] (3) The overall structure of the drive mechanism is reasonable. It can not only rotate with the rotating seat, but also make it easy to disengage the docking structure of the cutter shaft and the transition shaft through the handle, and make the docking structure dock through the spring. The disengagement and docking between the docking structures are very smooth, which greatly improves the convenience of operation. Attached Figure Description

Detailed Implementation

[0035] The invention will now be further described with reference to the accompanying drawings.

[0036] like Figure 1 and Figure 2 The orchard machine shown has optional rotary tillage and mowing functions. It has a front and rear traction frame 1 and an adjustment frame 2, which are connected by a lateral adjustment mechanism 3.

[0037] The traction frame 1 is a horizontally placed strip structure, with a rotating base 4 rotatably mounted at one end. A first hydraulic cylinder 5 connects the rotating base 4 and the adjusting frame 2 to control their relative rotation. A functional module is mounted on the rotating base 4; this module is either a rotary tillage module 6 or a weeding module 7. The rotary tillage module 6 and the weeding module 7 each include a cover, a blade shaft, and a blade assembly. Specifically, as shown... Figure 5 As shown, the rotary tillage module 6 includes a first cover 61, a first cutter shaft 62, and a rotary tillage blade assembly 63; as Figure 6 As shown, the weeding module 7 includes a second cover 71, a second blade shaft, and a weeding blade assembly 72. An orchard machine equipped with the weeding module 7 is shown below. Figure 8 As shown. The adjustment frame 2 is equipped with a drive mechanism 8, as... Figure 2 and Figure 3 As shown, the drive mechanism includes a hydraulic motor 81, a drive shaft 82, a universal joint 83, and a transition shaft 84, which are connected in sequence; the hydraulic motor 81 and the universal joint 83 are located at the two ends of the adjustment frame 2, respectively.

[0038] The end plate 41 of the rotating seat 4 has an upwardly open U-shaped groove 4a and two sliding grooves 4b located on both sides of the U-shaped groove 4a; the cover has two embedding parts a that can be embedded in the sliding grooves 4b; after the two embedding parts a are embedded in the two sliding grooves 4b on both sides of the U-shaped groove 4a, the end of the cutter shaft is placed in the U-shaped groove 4a; the sliding direction of the embedding part a when it is embedded in the sliding groove 4b is perpendicular to the axial direction of the cutter shaft.

[0039] The drive shaft 82 includes a first shaft portion 82a with a defined position and a second shaft portion 82b that can slide relative to the first shaft portion 82a. It also includes a spring 82c acting on the second shaft portion 82b, which causes the drive shaft 82 to have an elongation tendency as a whole. The adjustment frame 2 is equipped with a handle 85 that can drive the second shaft portion 82b to slide.

[0040] A retaining seat 91 is slidably mounted on the rotating seat 4, and the transition shaft 84 is connected to the retaining seat 91. The direction in which the retaining seat 91 slides relative to the rotating seat 4 is parallel to the axial direction of the cutter shaft. The transition shaft 84 can dock with the cutter shaft, and both have docking structures.

[0041] In use, when a functional module needs to be replaced, first turn the handle 85 to slide the second shaft 82b relative to the first shaft 82a, shortening the entire transmission shaft 82. This allows the transition shaft 84 to slide relative to the rotating seat 4, disengaging the cutter shaft of the current functional module from the transition shaft 84. Then, fix the handle 85 with the pin 810 to keep the cutter shaft and transition shaft 84 in the disengaged state. Next, slide the cover upwards, causing the insert a of the cover to slide out of the corresponding groove 4b. This allows for quick disassembly of the current functional module. When installing a new functional module, insert the insert a of the cover of the new functional module into the groove 4b, then pull the handle 85 back, extending the entire transmission shaft 82. The mating structure at the end of the transition shaft 84 abuts against the mating structure on the cutter shaft. Then, manually rotate the cutter shaft, ensuring that the mating structure of the cutter shaft and transition shaft 84 engages under the thrust of the spring 82c. In addition, both the cover and the rotating base 4 have positioning holes. After the two are connected, the positioning holes on the two are aligned with each other. By turning the knob by hand, the two can be connected, and the cover and the rotating base 4 can be fixed.

[0042] In addition, by controlling the extension and retraction of the first hydraulic cylinder 5, the rotation of the rotating seat 4 can be controlled, thereby controlling the pitching motion of the rotary tillage module 6 or the weeding module 7, and realizing the control of the attitude of the rotary tillage module 6 or the weeding module 7 to adapt to changes in terrain.

[0043] This invention improves the installation and transmission structures of an orchard machine with rotary tillage and mowing functions, achieving modularization of the rotary tillage module 6 and the weeding module 7. Through the coordinated operation of the transmission and installation structures, the functional modules can be quickly disassembled and replaced, significantly improving operational convenience and replacement efficiency. By quickly replacing the functional modules, it is unnecessary to purchase a complete rotary tiller and mower separately, thus reducing the overall mechanical costs of orchard maintenance.

[0044] Preferably, the end of the housing connected to the rotating seat 4 has an annular groove structure b arranged around the end of the cutter shaft, and the annular groove structure b can engage with the edge of the U-shaped groove 4a. This structure, with its double engagement of the insert a with the groove 4b and the annular groove structure b with the edge of the U-shaped groove 4a, improves the structural stability and reliability after installation. A third bearing seat c, supporting the cutter shaft, is mounted at the end of the rotating seat 4, and the annular groove structure b is arranged around the third bearing seat c.

[0045] Preferably, the rotating seat 4 has two side plates 42 arranged perpendicular to the end plate 41; each of the two side plates 42 is equipped with a guide rail 92, and the two sides of the retaining seat 91 slide relative to the corresponding guide rail 92. The two guide rails 92 are rotatably connected relative to the adjusting frame 2.

[0046] Preferably, the docking structure on the cutter shaft includes a first docking seat 10, such as... Figure 5 As shown, the first docking seat 10 has a main docking hole 10a and a plurality of square grooves 10b arranged around the main docking hole 10a, and the square grooves 10b are connected to the main docking hole 10a.

[0047] like Figure 4 As shown, the docking mechanism on the transition shaft 84 includes a second docking seat 20, which has a central shaft portion 20a and outward protrusions 20b arranged around the central shaft portion 20a and having the same number as the square grooves 10b; each outward protrusion 20b has a roller 20c at its front end, and the roller 20c has a portion that protrudes beyond the end of the central shaft portion 20a.

[0048] Using the above docking structure, during docking operations, the first docking seat 10 and the second docking seat 20 are relatively close. If the docking is successful, the roller 20c directly enters the corresponding square groove 10b to guide the central shaft 20a into the main docking hole 10a. If the docking is not successful, the roller 20c abuts against the end face of the first docking seat 10. When the user manually rotates the cutter shaft, the roller 20c rolls on the end face until the roller 20c enters the square groove 10b respectively. Under the thrust of the spring 82c, the central shaft 20a enters the main docking hole 10a.

[0049] Preferably, the adjusting frame 2 is a square tube structure, with a mounting base 30 fixed inside; the mounting base 30 has a first bearing seat 86 with a fixed position, and a second bearing seat 87 and a guide slider 88 for guiding the second bearing seat 87 are slidably mounted thereon; the first shaft portion 82a and the second shaft portion 82b are respectively mounted on the first bearing seat 86 and the second bearing seat 87. The hydraulic motor 81 is also mounted on the mounting base 30, and the hydraulic motor 81 is connected to the first shaft portion 82a via a coupling.

[0050] The drive shaft 82, the first bearing housing 86, the second bearing housing 87, and the hydraulic motor 81 are all mounted on the mounting base 30. After the above structure is assembled, it is installed in the adjustment frame 2, which can improve the assembly efficiency and protect the drive mechanism 8 to prevent impurities from winding and causing failure.

[0051] Preferably, the second shaft portion 82b has a pin 89, the handle 85 has a strip hole for the pin 89 to be inserted, and the handle 85 is hinged to the adjustment frame 2, and the handle 85 has a portion that extends beyond the adjustment frame 2 for easy operation.

[0052] The overall structure of the drive mechanism 8 is reasonably laid out. It can not only rotate with the rotating seat 4, but also facilitate the disengagement of the docking structure between the cutter shaft and the transition shaft 84 through the handle 85, and promote the docking structure to dock through the spring 82c. The disengagement and docking between the docking structures are very smooth, which greatly improves the convenience of operation.

[0053] Preferably, the lateral adjustment mechanism 3 includes a plurality of connecting frames 31 connected between the traction frame 1 and the adjustment frame 2, and also includes an adjusting cylinder 32 and a first reset spring 33 for adjusting the relative angle between the connecting frame 31 and the traction frame 1;

[0054] The regulating cylinder 32 is connected to the stroke valve 34; for example Figure 7 As shown, the lateral adjustment mechanism 3 further includes a rod 35 rotatable relative to the cover and a second return spring 37 acting on the rod 35. The rod 35 acts on the stroke valve 34 via a pull wire 36. Specifically, the rod 35 is mounted on a first frame 38 rotatably mounted relative to the cover, the second return spring 37 is placed between the first frame 38 and the cover, and the pull wire 36 acts on the stroke valve 34 via a second frame 39 rotatably connected relative to the adjustment frame 2. The end of the pull wire 36 can be detached relative to the first frame 38 to facilitate docking of the pull wire 36 with the first frame 38 on different working modules when changing working modules.

[0055] During operation, the rod 35 extends beyond the outer end of the cover. When the end of the rod 35 encounters an obstacle, the rod 35 rotates, which acts on the stroke valve 34 to release pressure from the regulating cylinder 32. The first reset spring 33 pulls the connecting frame 31 to make the regulating frame 2 move laterally to avoid the obstacle. After bypassing the obstacle, the rod 35 resets, the stroke valve 34 is not subjected to external force, the pressure in the regulating cylinder 32 is restored, and the regulating frame 2 is driven to reset.

[0056] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
