Description

Technical Field

[0001] The invention relates to the technical field of radish planting and harvesting, in particular to a radish planting and harvesting machine. Background Art

[0002] At present, radish planting and harvesting usually rely on two independent sets of mechanical equipment. Each device is equipped with an independent power system, which is used to drive the planting device and the harvesting device respectively. Although this division of labor can ensure the efficient execution of different processes, it also brings significant cost issues. First, the independent equipment design and power system increase the procurement cost of the overall equipment. The power system of each set of equipment requires additional investment, including power transmission devices, control systems, and multiple mechanical components, which makes the overall production cost higher. Secondly, the use and maintenance of equipment requires more resources and energy, and the management and maintenance of different equipment often require additional manpower and material investment.

[0003] In addition, existing equipment usually cannot achieve efficient power sharing between the planting and harvesting processes. Most of the power systems in the existing technology are optimized for a single process, which means that in actual application, the equipment needs to switch between planting and harvesting separately, and cannot achieve instant power conversion or sharing. This not only increases the complexity of equipment operation, but also leads to low energy utilization efficiency.

[0004] Therefore, the market urgently needs a comprehensive equipment design that can solve the above problems, so as to improve production efficiency, reduce equipment costs and reduce energy consumption. Summary of the invention

[0031] Beneficial effects of the present invention: 1. Reduce equipment costs. An integrated design solution is adopted to complete the planting and harvesting functions of radish through one device, avoiding the procurement cost of two independent sets of equipment in the traditional solution. By optimizing the power transmission components, the same power system can drive the planting device and the harvesting device, reducing the number and complexity of equipment and significantly reducing production costs.

[0032] 2. Improve the stability and reliability of power transmission.

The reverse arrangement and synchronous working mechanism of ratchet mechanism A and ratchet mechanism B effectively realize the diversion and switching of power, so that the drive motor can freely switch between driving the harvesting transmission mechanism and the sowing mechanism, stably driving the operation of the planting and harvesting system, thereby improving the reliability and working stability of the equipment.

[0033] 3. Simplify equipment operation and improve production efficiency. Through the design of the locking mechanism, the planting and harvesting modes can be quickly switched, so that the equipment does not need to frequently disassemble or adjust various mechanical parts during operation. This design greatly simplifies equipment operation and improves work efficiency. It is especially suitable for large-scale agricultural production, can achieve efficient and continuous operation, and reduces the difficulty of manual operation.

[0034] 4. Convenient disassembly and maintenance. The design of the locking mechanism and its telescopic shaft and telescopic sleeve in this solution facilitates the disassembly and maintenance of the equipment. It can realize the disassembly, assembly and replacement of the planting components and storage components. By adjusting the posture of the locking mechanism, the drive shaft B and the transmission shaft B can be easily separated or combined, ensuring that when the equipment needs to be repaired or parts replaced, no complicated operations are required, which greatly saves maintenance time and cost and reduces the difficulty of equipment maintenance.

[0035] In summary, this solution significantly improves the performance and economy of the radish planting and harvesting machine through integrated design, optimization of the power system and efficient structural layout. It not only reduces the equipment cost, but also improves the work efficiency, stability and energy utilization efficiency, greatly promoting the technological progress of agricultural mechanized equipment.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0039] See also Figure 1-4 , 6-8, a radish planting and harvesting machine, comprising a mounting frame 1 and a harvesting and transmission assembly 2 mounted on the mounting frame 1, and also comprising a planting assembly 3 and a storage assembly 4 selectively mounted on the mounting frame 1, wherein the planting assembly 3 and the storage assembly 4 are both arranged at the rear of the harvesting and transmission assembly 2.

[0040] The harvesting and transmission assembly 2 includes two groups of adjustment brackets 21, inclination adjustment mechanisms 22, and transmission mechanisms 23. The adjustment brackets 21 are rotatably mounted on the mounting frame 1. The inclination adjustment mechanism 22 is assembled on the mounting frame 1 and is linked with the adjustment brackets 21 on the corresponding side. The two groups of adjustment brackets 21 are equipped with transmission mechanisms 23.

[0041] The planting assembly 3 includes a mounting bracket A31 and a furrowing hoe 32, a sowing mechanism 33, and a soil covering mechanism 34 which are sequentially assembled on the mounting bracket A31 from front to back. The mounting bracket A31 is fixedly mounted on the mounting frame 1 in a detachable manner.

[0042] The storage assembly 4 includes a mounting bracket B41 and a storage box 42 arranged inside the mounting bracket B41. The mounting bracket B41 is fixedly mounted on the mounting frame 1 in a detachable manner.

[0043] It also includes a driving assembly 5 mounted on the mounting frame 1, a transmission mechanism 23 is connected to the driving assembly 5 by power, and a sowing mechanism 33 is connected to the driving assembly 5 by power in a detachable manner.

[0044] The mounting frame 1 is assembled and fixed with metal profiles to ensure its own structural strength. At the same time, it can ensure that the harvesting and transmission component 2, the planting component 3, the storage component 4 and the driving component 5 are stably installed and operated thereon, and the mounting frame 1 drives the components thereon to move stably in the field ridges, thereby completing the efficient planting and harvesting of radishes.

[0045] When harvesting radishes, the storage assembly 4 is assembled onto the mounting frame 1, and the inclination angle of the two sets of adjustment brackets 21 and the transmission mechanism 23 assembled on the adjustment brackets 21 are adjusted by operating the inclination adjustment mechanism 22, so that the front sides of the adjustment brackets 21 and the transmission mechanism 23 are lowered and act on the radishes planted in the ridges. The radishes are pulled out and transmitted backwards with the help of the transmission mechanism 23. When the radishes are transmitted backwards to the top of the storage box 42, the leaves on the radishes are cut off, and the radishes finally fall into the storage box 42 for collection, thereby realizing efficient harvesting of the radishes in the ridges.

[0046] The storage box 42 is installed in the mounting bracket A31 in a nested manner, so that the storage box 42 can be easily replaced after it is filled with radishes.

[0047] When planting radishes, the storage component 4 is removed, and the planting component 3 is assembled onto the mounting frame 1, and the driving component 5 is connected to the sowing mechanism 33 to achieve stable power transmission. At the same time, the adjustment bracket 21 and the transmission mechanism 23 thereon are lifted upward by manipulating the inclination adjustment mechanism 22 to prevent the transmission mechanism 23 from contacting the soil in the field ridges during the movement of the mounting frame 1 to interfere with the sowing process.

[0048] When the mounting frame 1 drives the sowing assembly to move between the ridges, the furrowing hoe 32 at the front can furrow the soil, and the sowing mechanism 33 at the rear is driven by the driving assembly 5 to evenly spread the radish seeds into the opened grooves, while the soil covering mechanism 34 at the rear covers the soil on both sides of the grooves back into the grooves to cover the seeds, thereby achieving the design requirement of efficient radish planting.

[0049] The mechanism shown in the figure includes a connecting frame 341 and a covering wheel 342. The connecting frame 341 is fixed to the mounting bracket A31 by bolts, and the covering wheel 342 includes two groups of covering wheels rotatably mounted on the connecting frame 341 and arranged symmetrically. The covering wheels 342 are arranged at an angle to push the soil on both sides of the groove into the groove. Example

[0050] See also Figure 5 In order to ensure that the mounting frame 1 can move and turn stably, and to ensure that the harvesting and transmission component 2, the planting component 3, and the storage component 4 can be stably installed and operated on the mounting frame 1, the following technical solution is provided.

[0051] Universal wheels 11 and driving wheels 12 are respectively mounted on the front and rear sides of the mounting frame 1 , and the universal wheels 11 and driving wheels 12 each include two groups arranged side by side.

[0052] The mounting frame 1 is provided with a clearance opening 13 and an assembly opening 14 arranged behind the clearance opening 13. A support frame 15 is fixedly connected to the mounting frame 1. An adjustment bracket 21 is rotatably mounted on the support frame 15. The adjustment bracket 21 and the transmission mechanism 23 are arranged in the clearance opening 13. The mounting bracket A31 and the mounting bracket B41 are fixedly mounted at the assembly opening 14.

[0053] The setting of the universal wheel 11 can ensure that the mounting frame 1 can turn effectively, and the driving wheel 12 is equipped with a hub motor to drive the driving wheel 12 to operate stably, thereby realizing the traveling function of the mounting frame 1.

[0054] The setting of the clearance opening 13 can ensure that the adjustment bracket 21 and the transmission mechanism 23 will not interfere with the spatial movement of the mounting frame 1 during the inclination adjustment process, and at the same time can ensure that the harvested radishes will not interfere with the spatial movement of the mounting frame 1 during the transmission process on the transmission mechanism 23.

[0055] The mounting bracket A31 and the mounting bracket B41 are both installed at the position of the assembly opening 14 by means of bolt fixing, so as to facilitate their disassembly, assembly and replacement. Example

[0056] See also Figure 6 , 9-11, in order to ensure that the transmission mechanism 23 can be stably installed and operated on the adjustment bracket 21, and realize the effective transmission of radishes and the cutting of radish leaves, the following technical solution is provided.

[0057] The transmission mechanism 23 includes a synchronous wheel A231, a pressure wheel 232, and a synchronous belt A233. The synchronous wheel A231 includes multiple groups that are rotatably mounted on the adjusting bracket 21 and maintained in a side-by-side arrangement. The synchronous belt A233 is wound around the periphery of each group of synchronous wheels A231 and is kept in mesh with the synchronous wheels A231. The pressure wheel 232 is rotatably mounted on the adjusting bracket 21 and is kept in close contact with the outer surface of the synchronous belt A233. A cutter disc 234 is coaxially fixed to one group of the synchronous wheels A231, and a reversing gear 235 is coaxially fixed to another group of the synchronous wheels A231.

[0058] The cutter discs 234 in the two transmission mechanisms 23 are symmetrically arranged, the reversing gears 235 in the two transmission mechanisms 23 are symmetrically arranged and kept in meshing, and one of the synchronous wheels A231 fixedly connected with the reversing gears 235 is in power connection with the driving assembly 5.

[0059] The combination of the synchronous wheel A231 and the synchronous belt A233 can enable the synchronous belt A233 to be stably installed along a specific running trajectory and drive the synchronous belt A233 to run stably. The reversing gears 235 in the two sets of transmission mechanisms 23 are engaged, which can enable the two sets of synchronous belts A233 to maintain reverse operation, thereby allowing the inner side of the synchronous belt A233 to clamp the radish leaves and stably transmit them diagonally to the rear.

[0060] The pressure wheel 232 is arranged on the outer side of the radish transmission action surface of the synchronous belt A233 to avoid spatial motion interference between the pressure wheel 232 and the transported radish, and can keep the synchronous belt A233 in a taut state to stably transmit the radish. At the same time, the pressure wheel 232 can increase the wrap angle of the synchronous belt A233 to the synchronous wheel A231 to ensure that each group of synchronous wheels A231 can achieve synchronous operation, thereby driving the knife disc 234 to operate stably.

[0061] The knife disc 234 is arranged below the corresponding synchronous wheel A231. The operating knife disc 234 can cut off the radish leaves transmitted thereto, and at this time, the radishes below are cut off and can fall stably into the storage unit below.

[0062] The blade disc 234 and the reversing gear 235 are both arranged at a rear position close to the adjusting bracket 21 , which can ensure that the radish leaves are cut when the radish is transferred to the top of the storage box 42 .

[0063] In order to ensure that the inclination adjustment mechanism 22 can be stably installed on the mounting frame 1 and realize effective adjustment of the inclination of the adjustment bracket 21, the following technical solution is provided.

[0064] The adjusting bracket 21 includes a fixed bracket 221, a lifting bracket 222, an adjusting screw 223, and a pin 224. The fixed bracket 221 is fixedly installed on the mounting frame 1 and arranged on the outer side of the adjusting bracket 21. The lifting bracket 222 is slidably installed on the fixed bracket 221 and moves up and down in the vertical direction. The adjusting screw 223 is rotatably installed in the fixed bracket 221 and is screwed to the lifting bracket 222. A horizontally arranged strip through groove 225 is fixedly connected to the lifting bracket 222. The pin 224 is fixedly connected to the adjusting bracket 21 and inserted into the strip through groove 225.

[0065] A vertically arranged guide rod 226 is also fixedly connected to the fixed bracket 221 , and the lifting bracket 222 is slidably plugged with the guide rod 226 to ensure that the lifting bracket 222 can be stably lifted and lowered in the vertical direction.

[0066] When the adjusting screw 223 is driven to operate, the lifting bracket 222 can be driven to be stably lifted and lowered in the vertical direction, so as to drive the pin rod 224 and the adjusting bracket 21 to be lifted and lowered synchronously in the vertical direction. Since the rear side end of the adjusting bracket 21 is hinged to the support frame 15 on the mounting frame 1, when the height of the front side end of the adjusting bracket 21 is adjusted, the pin rod 224 will have a horizontal displacement, and the setting of the strip through groove 225 can ensure that the pin rod 224 can move stably in the horizontal direction within a specific range, thereby realizing effective adjustment of the inclination angle of the adjusting bracket 21.

[0067] In order to achieve synchronous adjustment of the two groups of inclination adjustment mechanisms 22 and ensure synchronous adjustment of the inclinations of the two groups of adjustment brackets 21 and the transmission mechanisms 23 thereon, the following technical solution is provided.

[0068] The harvesting transmission assembly 2 also includes a transmission mechanism 24, which includes a driving shaft A241 and two sets of symmetrically arranged transmission shafts A242. The driving shaft A241 and the transmission shaft A242 are both arranged at the bottom of the mounting frame 1. Two sets of driving bevel gears A243 are fixedly connected to the driving shaft A241, and a driving bevel gear A244 and a driving bevel gear B245 are fixedly connected to the transmission shaft A242. The driving bevel gear A244 is meshed with the driving bevel gear A243, and a driving bevel gear B246 that is meshed with the driving bevel gear B245 is fixedly connected to the adjusting screw 223.

[0069] A knob 247 is fixedly connected to one end of the driving shaft A241, and the driving shaft A241 is driven to operate stably by the knob 247, and then the two sets of driving shafts A242 are driven to operate synchronously by the combination of driving bevel gear A243 and transmission bevel gear A244, and then the two sets of adjusting screws 223 are driven to operate synchronously by the combination of driving bevel gear B245 and transmission bevel gear B246, so as to realize the synchronous operation of the two sets of inclination adjustment mechanisms 22.

[0070] The transmission shaft A242 and the driving shaft A241 are both arranged at the periphery of the clearance opening 13 to prevent the transmission shaft A242 and the driving shaft A241 from causing spatial motion interference to the adjustment bracket 21, the transmission mechanism 23 and the transmitted radish. Example

[0071] See also Figure 12-14 In order to ensure that the driving assembly 5 can stably transmit power to the synchronous wheel A231 connected to its power, and to ensure stable power transmission during the process of adjusting the inclination angle of the adjusting bracket 21 and the transmission mechanism 23, the following technical solution is provided.

[0072] The driving assembly 5 includes a driving motor 51, a universal joint A521, a universal joint B522, a driving shaft B53, and two sets of ratchet mechanisms A541 and ratchet mechanisms B542 arranged in opposite directions. The driving motor 51 is dynamically connected to the ratchet mechanisms A541 and B542. One end of the universal joint A521 is fixedly connected to the synchronous wheel A231. The other end of the universal joint A521 is fixedly connected to a spline shaft 523. One end of the universal joint B522 is fixedly connected to a spline sleeve 524 that is slidably connected to the spline shaft 523. The other end of the universal joint B522 is linked to the ratchet mechanism A541. The ratchet mechanism B542 is linked to the driving shaft B53. The driving shaft B53 is dynamically connected to the sowing mechanism 33 through a locking mechanism 55.

[0073] An assembly bracket 16 is fixedly installed on the support frame 15, and the drive motor 51, the ratchet mechanism A541, and the ratchet mechanism B542 are all assembled on the assembly bracket 16. The combination of the universal joint A521, the universal joint B522, the spline shaft 523, and the spline sleeve 524 can adapt to the inclination adjustment of the adjustment bracket 21 and the transmission mechanism 23 to ensure that the power of the ratchet mechanism A541 is transmitted to the corresponding synchronous wheel A231 through the universal joint A521 and the universal joint B522, thereby driving the transmission mechanism 23 to operate stably.

[0074] The ratchet mechanism A541 and the ratchet mechanism B542 are arranged in opposite directions, and can select and transmit the running direction of the driving motor 51. When the driving motor 51 rotates forward, the transmission mechanism 23 can be driven to operate through the ratchet mechanism A541 to complete the harvesting of radishes. When the driving motor 51 rotates reversely, the driving shaft can be driven by the ratchet mechanism B542, and the locking mechanism 55 can drive the sowing mechanism 33 to operate to complete the sowing of radishes.

[0075] In order to ensure that the drive motor 51 can achieve power connection with the ratchet mechanism A541 and the ratchet mechanism B542, and the ratchet mechanism A541 and the ratchet mechanism B542 can achieve the design requirements of power diversion selection of the drive motor 51, the following technical solution is provided.

[0076] Ratchet mechanism A541 and ratchet mechanism B542 both include an inner ratchet 543, a mounting shaft 544, and a pawl 545. The mounting pawl 545 is rotatably mounted on the periphery of the mounting shaft 544. A spring is installed between the pawl 545 and the mounting shaft 544. The inner ratchet 543 is arranged on the periphery of the mounting shaft 544 and remains in mesh with the pawl 545.

[0077] The mounting shafts 544 of the ratchet mechanisms A541 and B542 are both fixedly connected with synchronous wheels B546. The two sets of synchronous wheels B546 are power-connected via synchronous belts B547. A transmission bevel gear C548 is fixedly connected to one set of the mounting shafts 544. A driving bevel gear C511 that meshes with the transmission bevel gear C548 is fixedly connected to the output shaft of the driving motor 51.

[0078] The inner ratchet 543 of the ratchet mechanism A541 is fixedly connected to the end of the universal joint B522, and the inner ratchet 543 of the ratchet mechanism B542 is fixedly connected to the driving shaft B53.

[0079] The inner ratchet 543 and the mounting shaft 544 in the ratchet mechanism A541 and the ratchet mechanism B542 are all rotatably installed on the assembly bracket 16. The driving motor 51 drives one group of the mounting shafts 544 to operate stably through the combination of the driving bevel gear C511 and the transmission bevel gear C548, and drives the two groups of mounting shafts 544 and the ratchet pawls 545 thereon to operate synchronously through the combination of the synchronous wheel B546 and the synchronous belt B547. Since the ratchet pawls 545 and the inner ratchet 543 in the two groups of ratchet mechanisms are arranged in reverse, when the mounting shaft 544 drives the ratchet pawls 545 thereon to operate around a specific direction, it can only drive the inner ratchet 543 of one group of the ratchet mechanisms to operate, so as to realize the diversion transmission of the power of the driving motor 51. Example

[0080] See also Figure 8 , 15 -17, in order to ensure that the sowing mechanism 33 can be stably installed and operated on the mounting bracket A31 and realize the power connection with the driving shaft B53, the following technical solution is provided.

[0081] The sowing mechanism 33 includes a mounting base plate 331, an outer sleeve 332, an inner sleeve 333, and a turntable 334. The mounting base plate 331 is fixedly mounted on the mounting bracket A31. A support member 3321 is fixedly connected to the bottom of the outer sleeve 332. The support member 3321 is fixedly mounted on the mounting base plate 331. The inner sleeve 333 is fixedly mounted on the support member 3321 and arranged on the inner side of the outer sleeve 332. The gap between the outer sleeve 332 and the inner sleeve 333 is set as a seed groove 335. The turntable 334 is arranged above the mounting base plate 331 and rotatably mounted on the bottom of the seed groove 335. A plurality of groups of inner through holes 3341 evenly distributed in the seed groove 335 are provided on the turntable 334. A group of outer through holes 3311 opposite to the inner through holes 3341 is provided on the mounting base plate 331.

[0082] The top of the inner sleeve 333 is designed to be conical, which is convenient for loading radish seeds into the seed groove 335. The setting of the support member 3321 can lift the outer sleeve 332 and the inner sleeve 333 to a certain height to ensure that the turntable 334 is stably installed at the bottom of the outer sleeve 332 and the inner sleeve 333.

[0083] The radish seeds in the seed groove 335 can fall into the inner through holes 3341 of the turntable 334. During the continuous rotation of the turntable 334, the inner through holes 3341 thereon will be opposite to the outer through holes 3311 on the mounting base plate 331 one by one. When the inner through holes 3341 are opposite to the outer through holes 3311, the radish seeds in the inner through holes 3341 can be dropped into the trench dug by the trenching hoe 32 through the outer through holes 3311.

[0084] A connecting shaft 3342 is fixedly connected to the axis center of the turntable 334, and the connecting shaft 3342 is rotatably installed at the axis center of the inner sleeve 333. A radially arranged transmission shaft B336 is rotatably installed on the outer sleeve 332 and the inner sleeve 333. A driving bevel gear D3361 is fixedly connected to the transmission shaft B336, and a transmission bevel gear D3343 that meshes with the driving bevel gear D3361 is fixedly connected to the connecting shaft 3342. The transmission shaft B336 is dynamically connected to the driving shaft B53 through a locking mechanism 55.

[0085] After the drive shaft B53 is connected to the transmission shaft power through the locking mechanism 55, the power of the drive motor 51 can be transmitted to the transmission shaft B336 through the drive shaft B53, and the connecting shaft 3342 and the turntable 334 are driven to operate stably through the combination of the driving bevel gear D3361 and the transmission bevel gear D3343.

[0086] In order to ensure that the power of the drive shaft B53 can be transmitted to the transmission shaft through the locking mechanism 55B, during the disassembly and assembly of the planting component 3, it is convenient to adjust the posture of the locking mechanism 55 to separate or combine the transmission shaft B336 and the drive shaft B53. The following technical solution is provided for this.

[0087] The locking mechanism 55 includes a locking joint 551, a locking groove 552, a telescopic shaft 553, a telescopic sleeve 554, and a support spring 555. The locking joint 551 is rotatably installed on the outer side of the outer sleeve 332. A driving bevel gear E5511 is fixedly connected to the bottom of the locking joint 551. A transmission bevel gear E3362 that meshes with the driving bevel gear E5511 is fixedly connected to the transmission shaft B336. The locking groove 552 and the locking joint 551 are nested and locked. The telescopic sleeve 554 is fixedly connected to the top of the locking groove 552. The telescopic shaft 553 is fixedly connected to the bottom of the driving shaft B53 and is slidably inserted into the tube of the telescopic sleeve 554. The support spring 555 is arranged on the periphery of the telescopic shaft 553, and both ends of the support spring 555 are kept in contact with the telescopic sleeve 554 and the telescopic shaft 553.

[0088] The combination of the telescopic shaft 553 and the telescopic sleeve 554 can ensure that the locking groove 552 can be stably raised and lowered in the vertical direction, which is convenient for controlling the combination and disassembly of the locking joint 551 and the locking groove 552. In a natural state, the support spring 555 can drive the telescopic sleeve 554 to slide downward under the action of its own elastic force, so that the locking groove 552 and the locking joint 551 can be stably locked and power transmitted. The power of the drive shaft B53 can be stably transmitted to the transmission shaft B336 through the telescopic shaft 553, the telescopic sleeve 554, the locking groove 552, the locking joint 551, the driving bevel gear E5511, and the transmission bevel gear E3362 in sequence.
