Description

Technical Field

[0001] This invention relates to a soil tillage device, and more particularly to an intelligent orchard rotary tiller. Background Technology

[0002] The lawn mowing and rotary tillage device is an intelligent agricultural machinery device mainly used for lawn mowing and rotary tillage operations in orchards. It provides more efficient, precise and convenient operation through intelligent technology. It is equipped with a control system with a positioning module, which can automatically identify fruit trees and rows, realize automated operation path planning and navigation, and improve operation efficiency.

[0003] Considering soil moisture, overly wet soil will stick to the blades of the rotary tiller, increasing cutting resistance during tilling, causing uneven rotation and affecting tilling efficiency. In addition, if there are too many weeds, the weeds covering the blades will also increase cutting resistance.

[0004] Due to the fixed blades of existing rotary tillage devices, if the above situation occurs, the machine needs to be stopped for inspection and maintenance, which is too time-consuming and affects the rotary tillage efficiency.

[0005] Therefore, how to design a grass-cutting rotary tillage device that can overcome the defects in the aforementioned prior art has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent orchard rotary tiller that can improve rotary tillage efficiency.

[0007] To achieve the above objectives, the present invention provides an intelligent orchard rotary tiller, comprising: a rotary tiller blade including multiple blade heads and multiple connecting components, the blade heads being disposed on the connecting components, the multiple connecting components being connected to each other and capable of rotating relative to each other; a drive mechanism connected to the connecting components to drive their rotation; and a telescopic drive member connected to the connecting components to change their rotation direction.

[0008] It also includes a machine compartment, in which the rotary tiller blade is disposed and both ends of the rotary tiller blade are rotatably connected to the machine compartment, the drive mechanism is disposed outside the machine compartment and the connecting component is connected to the drive end of the drive mechanism, and the telescopic drive component is disposed in the machine compartment.

[0009] The connecting assembly includes a toothed ring, a sun gear, multiple sets of first planetary gears, multiple sets of reversing gears, and a connecting frame. The toothed ring is connected to the cutter head. The sun gear is disposed inside the toothed ring. Adjacent sun gears are fixedly connected, and the sun gear near the drive end of the drive mechanism is connected to the drive end of the drive mechanism. The reversing gears are rotatably connected between the first planetary gears and the connecting frame. The first planetary gears and the reversing gears can switch between meshing with the sun gear and the toothed ring by axial movement. The connecting frame is connected to the drive end of the telescopic drive member.

[0010] The intelligent orchard mowing rotary tiller also includes a control device, and the connecting component also includes a rotary encoder. The input end of the rotary encoder is fixedly connected to the sun gear. The rotary encoder monitors the rotational speed of the sun gear and feeds it back to the control device. The control device controls the telescopic drive to change the rotation direction of the connecting component based on the rotational speed of the sun gear.

[0011] The reversing gear set includes a first spur gear and a second spur gear, which mesh with each other. The first spur gear can mesh with the ring gear, and the second spur gear can mesh with the sun gear.

[0012] The directional wheel assembly includes multiple connectors and multiple bearings. The connectors are located at the middle of the ends of the first spur gear and the second spur gear, and are fixedly connected to the first spur gear and the second spur gear through the inner ring of the bearing.

[0013] The steering wheel assembly is connected to the connecting frame by a connecting rod. The connecting rod includes two mounting sleeves with a mirror-shaped structure. The mounting sleeves have two slots that fit with the structure of the connecting head.

[0014] The cutter head includes multiple blades and multiple mounting bases, and the blades are connected to the connecting assembly via the mounting bases.

[0015] In this case, the blades of two adjacent cutting heads face each other.

[0016] In the two adjacent connecting components, one connecting component includes the first planetary gear and the reversing gear set, while the first planetary gear and the reversing gear set of the other connecting component are replaced by a second planetary gear, and the axial length of the second planetary gear is the same as the axial length of the first planetary gear and the reversing gear set combined.

[0017] Compared with existing technologies, the intelligent orchard mowing and rotary tiller provided by this invention has at least the following significant technical effects:

[0018] (1) The intelligent orchard weeding rotary tiller of the present invention has two connected blades that can rotate and change direction, thereby making the soil layer more evenly turned over and broken up, further increasing the looseness of the soil, which is conducive to the root growth of subsequent plants and the penetration of water; and, because it is the opposite rotation between the blades, the weeds and soil clods entangled between the blades are effectively torn apart, thereby indirectly ensuring the smoothness of the blade rotation.

[0019] (2) The intelligent orchard mowing rotary tiller of the present invention, wherein the blades of the rotary tillage blades can adjust the direction of the cutting edges of multiple blades according to the current geological conditions to be tilled, for example, making two sets of blades face each other. This not only ensures that the blades can till the land normally to the greatest extent, but also ensures a suitable distance between multiple blades, so as to avoid the situation where the distance between multiple blades is too small and excessive clay may adhere during the tillage process.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Attached Figure Description

[0058] To clearly explain the technical features of this invention, enabling those skilled in the art to clearly understand its structure, characteristics, usage, and technical effects, the following detailed embodiments, in conjunction with the accompanying drawings, illustrate the solution of this invention. However, the following descriptions are merely illustrative and are not intended to limit the scope of this invention.

[0059] Please refer to Figures 1 to 2 . Figure 1 This is a schematic diagram of the rotary tillage blades of an intelligent orchard mowing rotary tiller provided in a preferred embodiment of the present invention; Figure 2 This is a schematic diagram of the overall structure of the intelligent orchard mowing rotary tiller provided in a preferred embodiment of the present invention.

[0060] This invention provides an intelligent orchard rotary tiller, comprising a rotary tiller blade 2, a drive mechanism 3, and a telescopic drive member 4. The rotary tiller blade 2 includes multiple blade heads 21 and multiple connecting components 22. The blade heads 21 are disposed on the connecting components 22, and the multiple connecting components 22 are connected to each other and can rotate relative to each other. The drive mechanism 3 is connected to the connecting components 22 to drive their rotation. The telescopic drive member 4 is connected to the connecting components 22 to change their rotation direction.

[0061] Preferably, the intelligent orchard mowing rotary tiller also includes a machine compartment 1, the rotary tillage blade 2 is disposed inside the machine compartment 1 and both ends of the rotary tillage blade 2 are rotatably connected to the machine compartment 1, the drive mechanism 3 is disposed outside the machine compartment 1 and the connecting component 22 is connected to the drive end of the drive mechanism 3, and the telescopic drive component 4 is disposed in the machine compartment 1.

[0062] The drive mechanism 3 includes a gearbox and a universal joint. The rotor of a drive motor is connected to the input end of the drive mechanism 3 via its universal joint, and then connected to the connecting assembly 22 of the rotary tiller 2 via the output end of the drive mechanism 3.

[0063] The intelligent orchard rotary tiller of the present invention, during the process of mowing and tilling, first activates the drive mechanism 3, which drives the rotary tillage blades 2 to rotate, thereby achieving rotary tillage. Specifically, when the rotary tillage blades 2 rotate, the connecting components 22 respectively drive the blade heads 21 attached thereto to rotate, thus achieving rotary tillage.

[0064] The intelligent orchard rotary tiller of the present invention allows the rotary tiller blades 2 to rotate and change direction during rotary tillage via the telescopic drive member 4. Specifically, the telescopic drive member 4 changes the rotation direction of the connecting assembly 22, thereby causing the individual blades 21 on the connecting assembly 22 to change direction. The telescopic drive member 4 can be a hydraulic rod.

[0065] Please refer to Figures 5 to 8 . Figure 5 This is a structural disassembly diagram of the connecting components of the intelligent orchard mowing rotary tiller provided in a preferred embodiment of the present invention; Figure 6 The connection state (I) of the connection component of the intelligent orchard mowing rotary tiller provided in a preferred embodiment of the present invention; Figure 7 The connection state (II) of the connection component of the intelligent orchard mowing rotary tiller provided in a preferred embodiment of the present invention; Figure 8 This is a connection status diagram of multiple connecting components in an intelligent orchard mowing rotary tiller provided in a preferred embodiment of the present invention.

[0066] The connecting assembly 22 includes a toothed ring 221, a sun gear 222, multiple sets of first planetary gears 223, multiple sets of reversing gear sets 224, and a connecting frame 226. The toothed ring 221 is connected to the cutter head 21. The sun gear 222 is disposed inside the toothed ring 221. Adjacent sun gears 222 are fixedly connected to each other, and the sun gear 222 near the drive end of the drive mechanism 3 is connected to the drive end of the drive mechanism 3. The reversing gear sets 224 are rotatably connected between the first planetary gears 223 and the connecting frame 226. The first planetary gears 223 and the reversing gear sets 224 can switch meshing between the sun gear 222 and the toothed ring 221 by axial movement. The connecting frame 226 is connected to the drive end of the telescopic drive member 4.

[0067] The connecting assembly includes a cylindrical outer shell. The gear ring 211 is fixed to the inner wall of the cylindrical outer shell and connected to the cutter head 21 through the cylindrical outer shell. The sun gear 222, the first planetary gear 223, the reversing gear set 224, and the connecting frame 226 are housed in the internal cavity of the cylindrical outer shell. During rotary tillage, the drive shaft of the drive mechanism 3 is fixedly connected to the sun gear 222, driving the sun gear 222 to rotate. Meanwhile, the connecting frame 226 is extended or retracted by the external telescopic drive member 4, switching the engagement of the first planetary gear 223, the reversing gear set 224, and the gear ring 221.

[0068] When the first planetary gear 223 meshes with the gear ring 221 (e.g.) Figure 6 Assuming that the sun gear 222 rotates clockwise, the first planet gear 223 rotates counterclockwise based on the sun gear 222. Thus, the first planet gear 223 drives the gear ring 221 to rotate clockwise, so that the cutter head 21 connected to the gear ring 221 rotates in the same direction as the sun gear 222.

[0069] When the reversing wheel assembly 224 meshes with the gear ring 221 (e.g.) Figure 7 Assuming the sun gear 222 rotates clockwise, the reversing gear set 224 drives the gear ring 221 to rotate counterclockwise, causing the cutter head 21 connected to the gear ring 221 to rotate in the opposite direction to the sun gear 222.

[0070] In one embodiment, the initial state of the connecting assembly 22 corresponding to two adjacent cutter heads 21 can be set as follows:

[0071] The gear ring 221 connected to one of the cutter heads 21 meshes with the corresponding first planetary gear 223. In this state, the rotation direction of the gear ring 221 is the same as the rotation direction of the sun gear 222. The gear ring 221 connected to the other cutter head 21 meshes with the corresponding reversing gear set 224. In this state, the rotation direction of the gear ring 221 is different from the rotation direction of the sun gear 222. Thus, during the synchronous rotation of the multiple sun gears 222 by the drive mechanism 3, adjacent cutter heads 21 rotate in opposite directions, exhibiting staggered rotation.

[0072] To achieve this state, every two of these connection components 22 can be grouped into a connection set (e.g., Figure 8In each of the connecting sleeves, two connecting components 22 are respectively positioned opposite each other with their respective first planetary gears 223 (i.e., the two connecting components 22 are arranged in a flipped configuration), and a reversing gear set 224 is added between the opposing first planetary gears 223. One end of the added reversing gear set 224 is rotatably connected to one side of the first planetary gear 223, and the other end abuts against the other side of the first planetary gear 223. In this connecting sleeve, the toothed ring 221 of one side of the connecting component 22 engages with the first planetary gear 223, and the toothed ring 221 of the connecting component 22 of the other side engages with the reversing gear set 224. Meanwhile, adjacent connecting sleeves are positioned opposite each other by a connecting frame 226.

[0073] Alternatively, the two connecting components 22 in the connecting assembly can be connected end-to-end, and the connection configuration of one of the connecting components 22 can be changed. For example, the positions of the first planetary gear 223 and the reversing gear set 224 of one of the connecting components 22 can be swapped (i.e., replacing the sequential connection of the first planetary gear 223, the reversing gear set 224, and the connecting frame 226 with the sequential connection of the reversing gear set 224, the first planetary gear 223, and the connecting frame 226), and then the two connecting components 22 are connected end-to-end, with the two gear rings 221 respectively meshing with the first planetary gear 223 and the reversing gear set 224 of the two connecting components 22. In this embodiment, the adjacent cutter heads 21 also rotate alternately, and after the engagement state of the connecting components 22 is switched by the telescopic drive member 4, they still rotate alternately.

[0074] The lengths of the toothed ring 221, the first planetary gear 223, the reversing gear set 224, and the connecting brackets 226 on both sides can be set according to the actual situation, as long as it can ensure that when the telescopic drive 4 drives the multiple connecting components 22 to move forward and backward axially, the two adjacent connecting components 22 can switch the meshing state (from the state where the two toothed rings 221 are respectively meshed with the first planetary gear 223 and the reversing gear set 224, to the state where the two toothed rings 221 are respectively meshed with the reversing gear set 224 and the first planetary gear 2234).

[0075] In this embodiment, the initial state is that the adjacent cutter heads 21 rotate in opposite directions. After switching engagement, the two cutter heads 21 change their rotation direction at the same time and still rotate in opposite directions. Therefore, the weeds and soil stuck between the cutter heads 21 can be effectively torn apart, thereby indirectly ensuring the smooth rotation of the cutter heads 21.

[0076] In another embodiment, the initial state of the connecting assembly 22 corresponding to two adjacent cutter heads 21 can be set as follows:

[0077] The toothed rings 221 that engage with the cutter head 21 are all meshed with the corresponding first planetary gears 223, or the toothed rings 221 that engage with the cutter head 21 are all meshed with the corresponding reversing gear set 224. In this state, during the synchronous rotation of the multiple sun gears 222 driven by the drive mechanism 3, the multiple cutter heads 21 rotate in the same direction.

[0078] To achieve this state, the connecting components 22 can be arranged in a head-to-tail configuration, that is, the first planetary gear 223 of each connecting component 22 corresponds to the connecting frame 226 of another connecting component 22. The gear ring 221 meshes with the first planetary gears 223 of all the connecting components 22, or meshes with the directional gear set 224 of all the connecting components 22.

[0079] In this embodiment, the initial state is that the adjacent cutter heads 21 rotate in the same direction. After switching the meshing, the two cutter heads 21 change the direction of rotation, which can also remove tangled weeds and sticky soil clods.

[0080] The intelligent orchard mowing rotary tiller also includes a control device. The connecting component 22 also includes a rotary encoder. The input end of the rotary encoder is fixedly connected to the sun gear 222. The rotary encoder monitors the rotational speed of the sun gear 222 and feeds it back to the control device. The control device controls the telescopic drive 4 to change the rotational direction of the connecting component 22 based on the rotational speed of the sun gear 222.

[0081] During rotary tillage, the rotational speed of the sun gear 222 can be monitored in real time by a rotary encoder directly connected to the sun gear 222. If the rotation of the sun gear 222 is not smooth, the rotary encoder converts the monitored rotational speed into an electrical signal and feeds it back to the control device. The comparison module attached to the control device compares the signal with a preset rotational speed threshold. When the monitored rotational speed is lower than the threshold, the processor of the control system generates a conversion command to drive the telescopic drive 4 to extend or retract. The telescopic drive 4 then drives the connecting frame 226 to move axially based on the entire connecting assembly 22 until the first planetary gear 223 or the reversing gear set 224 connected to the current gear ring 221 is switched to the reversing gear set 224 or the first planetary gear 223, thereby changing the rotational direction of the current gear ring 221. The rotary encoder can be set in the middle of the sun gear 222, and is fixedly connected to the machine compartment 1 through one end of the rotary tillage blade 2 via an external fixed bracket.

[0082] The telescopic drive 4 can be connected to each of the connecting brackets 226 to control its back-and-forth movement in the axial direction, or the telescopic drive 4 can also be connected to the connecting bracket 226 of the connecting assembly 22 at the end, and its back-and-forth movement in the axial direction can be controlled by pushing at the end.

[0083] Please refer to Figures 9 to 11 . Figure 9 This is a partial structural disassembly diagram of the connecting components of the intelligent orchard mowing rotary tiller provided in a preferred embodiment of the present invention; Figure 10 This is a schematic diagram of the reversing wheel assembly of an intelligent orchard mowing rotary tiller provided in a preferred embodiment of the present invention; Figure 11 This is a side view of the reversing wheel assembly of an intelligent orchard mowing rotary tiller provided in a preferred embodiment of the present invention.

[0084] The directional gear set 224 includes a first spur gear 2241 and a second spur gear 2242. The first spur gear 2241 and the second spur gear 2242 mesh with each other. The first spur gear 2241 can mesh with the ring gear 221, and the second spur gear 2242 can mesh with the sun gear 222.

[0085] The deflector wheel assembly 224 also includes multiple connectors 2243 and multiple bearings 2244. The connectors 2243 are located at the middle of the ends of the first spur gear 2241 and the second spur gear 2242, and are fixedly connected to the first spur gear 2241 and the second spur gear 2242 through the inner ring of the bearings 2244.

[0086] When the reversing gear set 224 meshes with the gear ring 221, it is assumed that the sun gear 222 rotates clockwise. At this time, the second spur gear 2242 meshing with the sun gear 222 rotates counterclockwise. Based on this, the first spur gear 2241 rotates clockwise, and as the first spur gear 2241 rotates clockwise, the gear ring 221 rotates counterclockwise.

[0087] Please refer to Figure 12 . Figure 12 This is a structural disassembly diagram of the connecting rod of the intelligent orchard mowing rotary tiller provided in a preferred embodiment of the present invention.

[0088] A connecting rod 225 is provided between the steering wheel assembly 224 and the connecting frame 226. The connecting rod 225 includes two mounting sleeves 2251 with a mirror structure. The mounting sleeves 2251 have two rotating grooves 2252 that fit the structure of the connector 2243.

[0089] The mounting sleeve 2251 has a threaded groove 2253 on its side. A detachable connection between two mounting sleeves 2251 can be achieved by passing a screw 2254 through the threaded groove 2253. This split structure also facilitates maintenance and replacement when a single part is damaged.

[0090] The connecting frame 226 has multiple columns for mounting the first planetary gear 223 and the reversing gear set 224. The first planetary gear, the reversing gear set 224, the connecting rod 225, and the columns of the connecting frame 226 are connected sequentially. When the first planetary gear 223 rotates clockwise (or counterclockwise) along its own axis, the first spur gear 2241 and the second spur gear 2242 in the reversing gear set 224 will also revolve along the extension of the axis, simultaneously driving the connecting rod 225 to rotate clockwise (or counterclockwise). Therefore, the connecting rod 225 can be rotatably mounted on the multiple columns.

[0091] After the mounting sleeve 2251 is assembled, it can be fitted onto the outer wall of the corresponding connector 2243 through the rotating groove 2252 and based on the bearing 2244 to achieve a rotatable connection. The rotatable connection structure between the first planetary gear 223 and the directional gear set 224, or any other rotatable connection structure, can adopt the connection structure between the directional gear set 224 and the connecting rod 225.

[0092] Please refer to Figure 3 and Figure 4 . Figure 3 This is a front view of the rotary tillage blades of an intelligent orchard mowing rotary tiller provided in a preferred embodiment of the present invention; Figure 4 This is a side view of the rotary tillage blades of an intelligent orchard mowing rotary tiller provided in a preferred embodiment of the present invention.

[0093] The cutting head 21 includes multiple blades 211 and multiple mounting seats 212. The blades 211 are connected to the connecting assembly 22 via the mounting seats 212. Specifically, the blades 211 in the cutting head 21 are fixedly mounted on the toothed ring 221 of the corresponding connecting assembly 22 via the mounting seats 212. The connection between the mounting seats 212 and the toothed ring 221 can be welded. The blades 211 are inserted into the interior of the corresponding mounting seats 212 and then fixed with screws. With this structure, maintenance is easier when a single blade 211 is damaged and needs to be replaced.

[0094] The blades 211 of two adjacent cutter heads 21 face each other. Specifically, the cutting edge orientation of the blades 211 of the cutter head 21 can be adjusted according to the current geological conditions to be rotary tilled, so that the blades 211 of two adjacent sets of cutter heads 21 face each other. This ensures that the cutter head 21 can perform normal rotary tillage on the land, while also ensuring a suitable spacing between multiple cutter heads 21, so as to avoid excessive adhesion of clay during rotary tillage due to the spacing between multiple cutter heads 21 being too small.

[0095] Please refer to Figure 13 . Figure 13 This is a partial structural transformation diagram of the connecting components of the intelligent orchard mowing rotary tiller provided in another preferred embodiment of the present invention.

[0096] In another preferred embodiment, in the two adjacent connecting components 22, one connecting component 22 includes the first planetary gear 223 and the directional gear set 224, and the first planetary gear 223 and the directional gear set 224 of the other connecting component 22 are replaced by a second planetary gear 2231, and the axial length of the second planetary gear 2231 is the same as the axial length of the first planetary gear 223 and the directional gear set 224 combined.

[0097] In the above embodiment, the initial state and reversal process of the connecting component 22 corresponding to two adjacent cutter heads 21 can be set as follows:

[0098] One of the cutter heads 21 has a connecting assembly 22 consisting of the first planetary gear 223 and the reversing gear set 224 (e.g., the first planetary gear, the reversing gear set 224, the connecting rod 225, and the connecting bracket 226 are connected in sequence), while the connecting assembly 22 of the adjacent cutter head 21 is a second planetary gear 2231 replacing the first planetary gear 223 and the reversing gear set 224 (e.g., the second planetary gear 2231, the connecting rod 225, and the connecting bracket 226 are connected in sequence). Therefore, during the reversal of the cutting head 21, the connecting component 22 attached to one of the cutting heads 21 changes from the engagement of the first planetary gear 223 and the toothed ring 221 to the engagement of the reversing gear set 224 and the toothed ring 221, thereby realizing the reversal. Meanwhile, the connecting component 22 attached to the other cutting head 21 adjacent to it is always engaged by the second planetary gear 2231 and the corresponding toothed ring 221, and the corresponding cutting head 21 maintains its original rotation direction.

[0099] In this state, one of the blades 21 continues to rotate, while the adjacent blade 21 rotates in a different direction. Unlike soil tillage in the same direction, the two connected blades 21 switch between the same direction and opposite directions, which can make the soil layer more evenly turned over and broken up, thereby further increasing the looseness of the soil and facilitating the root growth of subsequent plants and the penetration of water.

[0100] Compared with existing technologies, the intelligent orchard mowing and rotary tiller provided by this invention has at least the following significant technical effects:

[0101] (1) The intelligent orchard weeding rotary tiller of the present invention has two connected blades that can rotate and change direction, thereby making the soil layer more evenly turned over and broken up, further increasing the looseness of the soil, which is conducive to the root growth of subsequent plants and the penetration of water; and, because it is the opposite rotation between the blades, the weeds and soil clods entangled between the blades are effectively torn apart, thereby indirectly ensuring the smoothness of the blade rotation.

[0102] (2) The intelligent orchard mowing rotary tiller of the present invention, wherein the blades of the rotary tillage blades can adjust the direction of the cutting edges of multiple blades according to the current geological conditions to be tilled, for example, making two sets of blades face each other. This not only ensures that the blades can till the land normally to the greatest extent, but also ensures a suitable distance between multiple blades, so as to avoid the situation where the distance between multiple blades is too small and excessive clay may adhere during the tillage process.

[0103] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the claims of the present invention.
