Modes for Carrying Out the Invention

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0023] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] As shown in Figures 1, 2, 3, 5 and 6, a structural diagram of an automatic ridge-making robot provided by an embodiment of the present invention includes a fixed frame 1, which is a hollow shell structure and has an opening at the bottom end. Support legs 2 are fixedly installed around the bottom wall of the fixed frame 1, and a walking module 21 is provided at the bottom end of the support legs 2. A ridge-making roller 3 is provided in the inner cavity of the fixed frame 1, and rotating columns 31 are fixedly installed at both ends of the ridge-making roller 3. The end of the rotating column 31 away from the ridge-making roller 3 is rotatably connected to the side wall of the fixed frame 1, and a first motor 32 is fixedly installed on the side wall of the fixed frame 1. The output shaft of the first motor 32 is connected to a group of rotating columns 31. A digging mechanism 4 is provided on the surface of the ridge-making roller 3, and the digging mechanism 4 includes a column 41, a storage assembly 42 and a telescopic assembly 43. The columns 41 are provided in multiple groups and are distributed in parallel along the axis direction of the ridge-making roller 3. The storage assembly 42 is located on the surface of the ridge-making roller 3 and is connected to the column 41 Then, the storage assembly 42 is used to control the column 41 to be located inside the ridge-making drum 3 as a whole. The telescopic assembly 43 includes a transmission part 431 and a control part 432. The transmission part 431 is located inside the ridge-making drum 3 and is connected to the column 41. The control part 432 is located inside the ridge-making drum 41 and is connected to the transmission part 431. When the ridge-making drum 3 drives the column 41 to rotate to the lowest point, the control part 432 controls the column 41 to extend to the outside of the ridge-making drum 3 and insert it into the soil by cooperating with the transmission part 431. The inner cavity of the fixed frame 1 is rotatably installed with a fixed cylinder 6, and a piercing mechanism 7 is provided on the surface of the fixed cylinder 6. The piercing mechanism 7 includes an insertion rod 71 and a guide assembly 72. The insertion rod 71 is provided in multiple groups and is evenly distributed on the annular surface of the fixed cylinder 6. The guide assembly 72 is located in the fixed cylinder 6 and is connected to the insertion rod 71. When the fixed cylinder 6 rotates, the guide assembly 72 is used to adjust the position of the insertion rod 71 in real time.

[0025] When in use, the walking module 21 cooperates with the supporting legs 2 to push the fixed frame 1 to walk between the soil fields. While the fixed frame 1 is moving, the first motor 32 cooperates with the rotating column 31 to push the furrowing roller 3 to rotate. The furrowing roller 3 can efficiently perform furrowing and leveling processing on the soil when rotating. The furrowing roller 3 drives the column 41 to rotate synchronously while rotating. When the column 41 rotates to the lowest point, the control part 432 cooperates with the transmission part 431 to control the column 41 to extend to the outside of the furrowing roller 3, and the column 41 is inserted into the leveled soil. When the column 41 is inserted into the soil, a planting hole can be formed. The ridge-making drum 3 drives the column 41 to rotate continuously. The control part 432, the transmission part 431 and the storage component 42 cooperate with each other to control the column 41 to move into the inside of the ridge-making drum 3. While the ridge-making drum 3 is making ridges and leveling the soil, the fixed cylinder 6 rolls synchronously on the leveled soil surface. When the fixed cylinder 6 rolls, the guide component 72 can automatically adjust the position of the insertion rod 71. When the insertion rod 71 moves to the lowest point, the guide component 72 controls the insertion rod 71 to move to the outside of the fixed cylinder 6 and insert it into the soil. The insertion rod 71 can automatically insert holes into the leveled soil to facilitate the soil in the deep layer to fully contact with the air.

[0026] As shown in Figures 1, 4 and 6, as a preferred embodiment of the present invention, the storage assembly 42 includes a plurality of groups of parallel distributed storage grooves 421 opened on the surface of the bed-making drum 3, the column 41 is slidably installed in the storage groove 421, and a limiting groove 422 is opened on the side wall of the storage groove 421. The side wall of the column 41 is fixedly installed with a limiting block 423 that is slidably connected to the limiting groove 422.

[0027] Initially, the column 41 is in the receiving groove 421, and the limit block 423 slides in the limit groove 422, which can control the column 41 to slide synchronously in the receiving groove 421. When the bed-making roller 3 drives the column 41 to rotate to the lowest point, the transmission part 431 controls the column 41 to move toward the outside of the receiving groove 421, and the column 41 is inserted into the leveled soil. When the column 41 is inserted into the soil, a planting hole can be formed. The bed-making roller 3 drives the column 41 to rotate continuously, and the transmission part 431 controls the column 41 to move back into the receiving groove 421.

[0028] As shown in Figures 1, 2, 3 and 6, as a preferred embodiment of the present invention, the transmission part 431 includes a threaded hole 4311 opened on the surface of the column 41, and a threaded rod 4312 threadedly connected to the threaded hole 4311 is rotatably installed in the receiving groove 421. A transmission cavity 4313 corresponding to the multiple groups of receiving grooves 421 is opened inside the ridge-making drum 3, and the end of the threaded rod 4312 away from the column 41 extends into the transmission cavity 4313 and is fixedly installed with a synchronous gear disc 4314. The multiple groups of synchronous gear discs 4314 are commonly connected to the first synchronous belt 4315. A second motor 4316 is fixedly installed in the transmission cavity 4313, and the output shaft of the second motor 4316 is connected to a group of threaded rods 4312.

[0029] When the furrow roller 3 drives the column 41 to rotate to the lowest point, the control unit 432 starts the second motor 4316, and the second motor 4316 drives a group of threaded rods 4312 to rotate and then drives the synchronous gear plate 4314 to rotate. Multiple groups of synchronous gear plates 4314 cooperate with the first synchronous belt 4315 to drive multiple groups of threaded rods 4312 to rotate synchronously. When rotating, the threaded rods 4312 push the column 41 toward the inside and outside of the telescopic slot 421. After the column 41 moves toward the outside of the telescopic slot 421 to the extreme position, the control unit 432 controls the second motor 4316 to rotate in the opposite direction. The second motor 4316 drives multiple groups of threaded rods 4312 to rotate in the opposite direction, and the threaded rods 4312 control the column 41 to move in the opposite direction into the storage slot 421.

[0030] As shown in Figures 1, 2, 3 and 6, as a preferred embodiment of the present invention, the control unit 432 includes a control chamber 4321 opened inside the ridge-making drum 3, a PLC controller 4322 is fixedly installed in the control chamber 4321, the PLC controller 4322 is electrically connected to the second motor 4316, a power supply 4323 is fixedly installed in the control chamber 4321, a sliding block 4325 is slidably installed in the control chamber 4321, the sliding block 4325 is made of magnetic material, a magnetic plate 4324 that cooperates with the sliding block 4325 is fixedly installed on the top wall of the control chamber 4321, and two groups of relatively distributed conductive sheets 4326 are fixedly installed on the bottom wall of the control chamber 4321 and the bottom wall of the sliding block 4325 respectively.

[0031] When the bedding roller 3 rotates, it will drive the control chamber 4321 to rotate synchronously. Initially, the magnetic plate 4324 uses magnetic attraction to adsorb and position the sliding block 4325. When the column 41 rotates to the lowest point and is in a vertical state, the vertical downward gravity of the sliding block 4325 is greater than the magnetic attraction of the magnetic plate 4324, and the sliding block 4325 falls to the bottom of the control chamber 4321. At this time, the two sets of conductive plates 4326 are connected to form a circuit path, and the PLC controller 4322 controls the second motor 4316. The C controller 4322 controls the second motor 4316 to rotate forward first, and then the PLC controller 4322 controls the second motor 4316 to rotate reversely. Finally, the PLC controller 4322 stops running by itself, and the ridge-making drum 3 continues to rotate. The sliding block 4325 slides to the side of the magnetic plate 4324 again, and the magnetic plate 4324 fixes the position of the sliding block 4325 again. When the column 41 rotates to the lowest point again and is in a vertical state, the above steps are repeated, and automatic hole digging can be performed while ridge making.

[0032] As shown in FIG3 and FIG4 , as a preferred embodiment of the present invention, the inner cavity of the fixing frame 1 is provided with a cleaning component 5 that cooperates with the bedding roller 3 , and the cleaning component 5 is used to clean the soil attached to the surface of the bedding roller 3 .

[0033] When the bedding drum 3 rotates to form the soil, a small amount of soil will adhere to the surface of the bedding drum 3 . The cleaning component 5 can automatically clean the soil adhered to the surface of the bedding drum 3 .

[0034] As shown in Figures 3 and 4, as a preferred embodiment of the present invention, the cleaning assembly 5 includes a cleaning rod 51 rotatably installed in the inner cavity of the fixed frame 1 and located on the outside of the bedding drum 3. A plurality of groups of evenly distributed brushes 52 are provided on the surface of the cleaning rod 51. A first fixed toothed disc 53 is fixedly installed on the surface of the rotating column 31. A second fixed toothed disc 54 is fixedly installed on the surface of the cleaning rod 51. The first fixed toothed disc 53 and the second fixed toothed disc 54 are commonly connected to a second synchronous belt 55.

[0035] The rotation of the rotating column 31 drives the first fixed gear disc 53 to rotate synchronously. The first fixed gear disc 53 cooperates with the second synchronous belt 55 to drive the second fixed gear disc 54 to rotate. The second fixed gear disc 54 drives the cleaning rod 51 to rotate. The cleaning rod 51 drives the brush 52 to rotate. The brush 52 can clean the soil attached to the surface of the ridge-making drum 3 in all directions.

[0036] As shown in Figures 1, 2, 4 and 7, as a preferred embodiment of the present invention, the guide assembly 72 includes a plurality of groups of annularly distributed telescopic cavities 721 opened inside the fixed cylinder 6, a bearing plate 722 is slidably installed in the telescopic cavity 721, a counterweight block 725 is provided in the telescopic cavity 721, the counterweight block 725 is made of magnetic material, a magnetic positioning block 726 that cooperates with the counterweight block 725 is fixedly installed on the top wall of the telescopic cavity 721, a plurality of groups of through holes 724 that are connected to the telescopic cavity 721 are opened inward on the surface of the fixed cylinder 6, the insertion rod 71 is located in the through hole 724 and is connected to the bottom wall of the bearing plate 722, and a plurality of groups of extrusion springs 723 that surround the outside of the insertion rod 71 and are connected to the bearing plate 722 are fixedly installed in the telescopic cavity 721.

[0037] Initially, the magnetic positioning block 726 uses magnetic attraction to adsorb and position the counterweight block 725, and the rotation of the fixed cylinder 6 drives the telescopic cavity 721 and the insertion rod 71 to rotate synchronously. When the insertion rod 71 rotates to the lowest point and is in a vertical state, the vertical downward gravity of the counterweight block 725 is greater than the magnetic attraction of the magnetic positioning block 726. The counterweight block 725 falls freely in the telescopic cavity 721, and the counterweight block 725 impacts the supporting plate 722. The supporting plate 725 pushes the insertion rod 71 toward the outside of the through hole 724. The insertion rod 71 can automatically drill holes on the soil surface to facilitate contact between deep soil and air.

[0038] The working principle of the present invention is: when in use, the walking module 21 cooperates with the supporting legs 2 to push the fixed frame 1 to walk between the soil fields. While the fixed frame 1 is moving, the first motor 32 cooperates with the rotating column 31 to push the ridge-making roller 3 to rotate. The ridge-making roller 3 can efficiently make ridges and level the soil when rotating. The ridge-making roller 3 drives the column 41 to rotate synchronously while rotating. When the column 41 rotates to the lowest point, the vertical downward gravity of the sliding block 4325 is greater than the magnetic attraction of the magnetic plate 4324, and the sliding block 4325 falls to the bottom of the control cavity 4321. At this time, the two sets of conductive plates 4326 are connected to form a circuit path, and the PLC controller 4322 controls the second motor 4316. The PLC controller 4322 controls the second motor 4316 to rotate forward first, and the second motor 43 16 drives a group of threaded rods 4312 to rotate and then drives the synchronous gear plate 4314 to rotate. Multiple groups of synchronous gear plates 4314 cooperate with the first synchronous belt 4315 to drive multiple groups of threaded rods 4312 to rotate synchronously. The threaded rods 4312 push the column 41 to move toward the inside and outside of the telescopic slot 421 when rotating. After the column 41 moves to the outside of the telescopic slot 421 to the extreme position, the PLC controller 4322 controls the second motor 4316 to reverse. Finally, the PLC controller 4322 stops running automatically, and the ridge-making drum 3 continues to rotate. The sliding block 4325 slides to one side of the magnetic plate 4324 again, and the magnetic plate 4324 fixes the position of the sliding block 4325 again. When the column 41 rotates to the lowest point again and is in a vertical state, the above steps are repeated, and automatic hole digging can be performed while ridge making.

[0039] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
