Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery and equipment technology, specifically relating to an integrated machine for harvesting and planting lettuce. Background Technology

[0002] In the current lettuce cultivation industry, there are many problems with the equipment used in the planting and harvesting stages. Existing planting equipment is mostly simple sowing devices with limited functionality. These devices struggle to precisely control the spacing and depth of lettuce seed sowing, resulting in uneven germination rates and inconsistent seedling growth, ultimately affecting yield. Current harvesting equipment is largely designed for general vegetables and is ill-suited to the unique growth morphology and texture of lettuce. During harvesting, lettuce stems often break, and the skin is often scratched, severely impacting the commercial value of the lettuce. Furthermore, existing equipment is inefficient in harvesting, failing to meet the high-efficiency harvesting needs of lettuce farms during the harvest season.

[0003] Furthermore, with the acceleration of agricultural modernization, large-scale and intensive lettuce cultivation is gradually emerging, placing higher demands on the multifunctionality and intelligence of equipment. Existing planting and harvesting equipment operates in a decentralized manner, failing to achieve integrated and intelligent continuous operation, which consumes significant manpower and resources and reduces production efficiency. In conclusion, developing an integrated machine that combines planting and harvesting functions, enables precise operation, adapts to the needs of lettuce at different growth stages, and possesses a high degree of intelligence and automation has become a critical issue that the lettuce cultivation industry urgently needs to address.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 9 , Figure 10 , Figure 11As shown, the specific structure of the conveying and collecting unit is as follows: two fixed plates 15 are fixed to the frame 13 by fixing bolts, and a conveyor belt 14 is installed between the two fixed plates 15. The end of the conveyor belt 14 along the running direction is fastened to the side wall of the packing trough 17 by fixing bolts. A sliding plate 18 is installed inside the packing trough 17, which can smoothly guide the conveyed lettuce into the trough. Two binding machines 19 are placed side by side in the packing trough 17. The binding machines 19 are connected to a programmable logic controller (PLC) and then electrically connected to a battery control box 62. The battery pack 61 provides working voltage to the binding machines 19 through the battery control box 62. The battery control box 62 executes the binding process of the lettuce through the PLC, realizing the start-stop and tension adjustment control of the binding machines 19. A pusher 20 is set between the two binding machines 19, and the pusher 20 is located below the conveyor belt 14. The pusher 20 is connected to the pusher motor 56 below the conveyor belt 14. The power of the pusher 20 is provided by the pusher motor 56, and the power is transmitted to the pusher 20 through the belt drive device in the transmission box 76. The screw inside the pusher 20 rotates, converting the rotational motion into the linear motion of the pusher rod, thereby realizing the material pushing function. The rear of the packaging trough 17 is provided with a movable sliding plate 23. The pusher 20 can quickly push the packaged lettuce to the movable sliding plate 23 in the packaging trough 17. The collection trough 24 is connected to the rear of the packaging trough 17. When the movable sliding plate 23 flips, the lettuce slides into the collection trough 24, forming a continuous automated packaging and collection process. A discharge gripper fixing frame 21 is installed on one side of the packaging trough 17. The discharge gripper 22 is connected to the top of the discharge gripper fixing frame 21 by bolts, thereby realizing the precise discharge of the packaged lettuce. An additional column-mounted camera B77 is installed on the top of the collection tank 24. Its function is to acquire images in real time and provide precise position guidance for the unloading gripper 22, thereby achieving precise collaborative operation with the unloading gripper 22. These components work together to form a complete mechanical working system.

[0038] like Figure 1 , Figure 3 , Figure 4 , Figure 11 , Figure 15As shown, the specific structure of the power control system unit is as follows: it includes a generator 25, which is located on one side of the conveyor belt 14 and above the frame 13. The generator 25 serves as the core power source, supplying the necessary electrical energy for the stable operation of the entire equipment system and ensuring the coordinated operation of all components. On the other side of the conveyor belt 14, above the frame 13, a pump station 26, a battery control group 27, a seat 28, and a display screen 29 are arranged sequentially. The battery control group 27 is connected to the generator 25 via a cable. As the core of the system, the battery control group 27 consists of a battery pack 61, a battery control box 62, and a hydraulic control box 63. The battery pack 61 is connected to the battery control box 62 via a power supply line, providing voltage to the battery control box 62. The battery control box 62 interacts bidirectionally with the hydraulic control box 63 via a control line and provides operating power to the hydraulic control box 63. The electrical energy generated by generator 25 is transmitted to battery pack 61 via cable for storage. Battery control box 62 parses the input commands on display screen 29, converts the commands into control signals, and schedules battery pack 61 to release electrical energy as needed to provide power for the entire system. Hydraulic control box 63, connected to battery control box 62, receives control signals output by battery control box 62 and obtains electrical energy from battery pack 61, converting the electrical energy into drive signals to drive pump station 26 to operate stably and achieve hydraulic power output. Pump station 26 delivers hydraulic fluid to hydraulic cylinder 39 and small hydraulic cylinder 42 through hydraulic pipelines. Valve groups and pressure sensors in hydraulic control box 63 regulate hydraulic flow, direction, and pressure in real time to ensure stable operation of the two hydraulic cylinders. The seat 28 is designed to balance operation convenience and observation field. Operators can monitor the equipment operation status in real time through display screen 29, complete human-machine interaction, and realize fully automated control of the entire process from lettuce conveying, packaging to collection.

[0039] like Figure 1 , Figure 3 , Figure 4 , Figure 11 As shown, the frame 13 is securely connected to the connecting frame 33 by fixing bolts. A hub 31 is provided below the connecting frame 33. A power motor 30 is installed on the connecting frame 33. The output shaft of the power motor 30 is connected to the hub 31. The power motor 30 starts to run after receiving the electrical signal from the electronic control component, converting electrical energy into mechanical energy. The transmission shaft transmits the energy to the hub 31, and the hub 31 meshes with the track plate 32, thereby driving the track to run smoothly and realizing the movement function of the equipment.

[0040] like Figure 1 , Figure 4 , Figure 12 , Figure 14As shown, the specific structure of the soil turning and ditching unit is as follows: the long pad plate 34 and the short pad plate 35 are installed at the bottom of the frame 13 by fixing bolts. The short pad plate 35 is connected to the support plate 36. A rotary tillage component 37 is installed between the two support plates 36. The rotary tillage component 37 breaks up the residual leaves on the ground by high-speed rotation, and at the same time loosens the soil, which can effectively improve the soil texture and create more suitable conditions for the subsequent ditching and sowing process. The motor 38 is connected to the support plate 36, and a motor gear 64 is installed inside the support plate 36. The motor gear 64 meshes with the rotary tillage component gear 65 of the rotary tillage component 37. The mechanical energy output by the motor 38 is precisely transmitted to the rotary tillage component gear 65 via the motor gear 64 installed inside the support plate 36. The rotary tillage component gear 65 drives the rotary tillage component 37 to operate continuously through stable gear meshing, providing sufficient kinetic energy for soil tillage. One side of the hydraulic cylinder 39 is fixed to the bottom of the frame 13, and the other side of the hydraulic cylinder 39 is connected to the support plate 36. The hydraulic cylinder 39 controls the hydraulic flow, direction, and pressure in real time through the hydraulic control box 63, thereby controlling the rotary tillage component. The lifting and lowering action of component 37 is achieved by mounting the support frame 40 to the bottom of the frame 13 with fixing bolts. The support frame 40 is connected to the trenching component 41 below. In order to achieve precise control of the trenching depth, a small hydraulic cylinder 42 is installed on the trenching component 41. The piston end of the small hydraulic cylinder 42 is connected to the trenching component 41, and the cylinder body side of the small hydraulic cylinder 42 is connected to the support frame 40. The small hydraulic cylinder 42 is also connected to the hydraulic control box 63. The small hydraulic cylinder 42 adjusts the hydraulic flow, direction and pressure in real time through the hydraulic control box 63, thereby providing the lifting and lowering of the trenching component 41, so as to achieve precise control of the trenching depth and meet the different depth requirements of seed sowing.

[0041] like Figure 1 , Figure 5 , Figure 13 , Figure 16 , Figure 17 , Figure 18As shown, the specific structure of the sowing and fertilization unit is as follows: it includes a traction plate 44, one side of which is connected to the frame 13, and the other side of which is connected to one side of the planting frame 45. The other side of the planting frame 45 is connected to the connecting plate 54 via an L-shaped bracket 53 and bolts. A sowing device 46 and a fertilization device 49 are integrated and installed on the top of the planting frame. The sowing device 46 includes a seed box 68, which is mounted on a gear guide housing 71 via a support member 69. The gear guide housing 71 is fixed to the planting frame 45, and a gear guide column 7 is provided inside the gear guide housing 71. 0. One end of the gear guide column 70 extends out of the gear guide housing 71 and meshes with the output device of the sowing motor. The gear guide column 70 and the gear guide housing 71 form a cavity. The bottom of the gear guide housing 71 is connected to one end of a pair of conveying hoses 72. The other end of the pair of conveying hoses 72 is suspended above the ground. The sowing motor 48 drives the gear guide column 70 to rotate through gear transmission. Seeds fall from the seed box 68 through the support member 69 into the rotating gear guide column 70. The seed conveying frequency is controlled by adjusting the speed of the guide column. Finally, the seeds are evenly sown on the ground through the conveying hoses 72. The fertilization device 49 comprises a fertilizer box 73, a fertilizer tray 74, and an adjuster 75. The fertilizer box 73 has a hollow bottom, which is connected to the fertilizer tray 74 via a conduit. The bottom of the fertilizer tray 74 is connected to the output shaft of the fertilization motor 50. Fertilizer falls from the fertilizer box 73 into the fertilizer tray 74. The fertilization motor 50 drives the fertilizer tray to rotate, achieving the spreading operation. The adjuster 75 at the bottom of the fertilizer box can precisely adjust the size of the dispensing opening to control the fertilization rate and adapt to different operating scenarios. The device also includes a seeding motor 48 and a fertilization motor 50. The power control of both systems is based on a battery control system: the seeding motor 48 is connected to the battery control box 62 via a motor controller. The operator inputs commands through the display screen 29, and the battery control box 62 analyzes the commands to generate control signals, scheduling the battery pack 61 to supply power to the seeding motor 48, achieving quantitative seed dispensing through gear transmission; the fertilization motor 50 is installed on the planting frame 45 and connected to the battery control box 62 via an independent controller. The battery control box 62 schedules electrical energy according to command signals to drive the fertilization device 49 to complete quantitative fertilizer application. The two systems work collaboratively through a unified electronic control platform to achieve automated and precise control of the seeding and fertilization processes.The planting frame 45 is connected to the mulching device 51 and four casters 52 at the bottom. The mulching device 51 consists of a mulching connecting block 66, a mulching component 67, and a small hydraulic cylinder 42. One side of the mulching connecting block 66 is fixedly connected to the planting frame 45, and the other side is hinged to the mulching component 67 via a horizontal pin, forming a rotatable pivot structure. The bottom of the cylinder body of the small hydraulic cylinder 42 is hinged to the mulching connecting block 66 via a trunnion. The top of the piston rod of the small hydraulic cylinder 42 is connected to the outer support of the mulching component 67. The oil inlet and outlet of the small hydraulic cylinder 42 are connected to the pump station 26 via hydraulic oil pipes. When the hydraulic control box 63 adjusts the hydraulic oil flow direction of the pump station 26, the piston rod of the small hydraulic cylinder 42 performs a telescopic movement, which pushes the mulching component 67 to rotate around the horizontal pin to adapt to different soil covering thickness requirements. The mulching device 51 is responsible for applying a layer of soil on top of the seeds as a barrier to prevent the fertilizer applied by the fertilization device 49 from directly contacting the seeds, thereby protecting the seeds from potential damage. Combine. Figure 5 , Figure 13 , Figure 17 The soil covering component 55 includes a rotating shaft, with both ends of the rotating shaft movably connected to circular connecting plates. A soil covering roller is positioned between the pair of circular connecting plates. The soil covering roller is designed to be hollow. Both ends of the rotating shaft are also connected to the planting frame 45 via connecting plates 54, forming a liftable working unit. The bottom of the cylinder body of the hydraulic cylinder 39 is hinged to the L-shaped bracket 53 via trunnions. The L-shaped bracket 53 is fastened to the planting frame 45 via fixing bolts, forming a stable support structure. The piston end of the hydraulic cylinder 39 is connected to the connecting plate 54 via bolts. The movement of the hydraulic cylinder 39 is precisely controlled by the hydraulic control box 63, which regulates the flow of hydraulic oil from the pump station 26. When operation is required, the hydraulic oil pushes the piston rod to extend, causing the soil covering component 55 to descend to a set height and contact the ground. After the operation is completed, the piston rod retracts, lifting the soil covering component 55 to a suspended state to avoid wear on the component. The soil covering component 55 adopts a hollow grid plate structure, which can evenly spread the surface soil on top of the fertilizer layer as the frame moves, completing the final soil covering process.

[0042] Both the seeding motor 48 and the fertilizer motor 50 are installed inside a motor protective housing, which prevents soil particles from eroding the motor and provides it with reliable protection.

The L-shaped bracket 53 is fastened to the planting frame 45 via fixing bolts, forming a stable support structure. The piston end of the hydraulic cylinder 39 is connected to the connecting plate 54 via bolts. The movement of the hydraulic cylinder 39 is precisely controlled by the hydraulic control box 63, which regulates the flow of hydraulic oil from the pump station 26. When operation is required, the hydraulic oil pushes the piston rod to extend, causing the soil covering component 55 to descend to a set height and contact the ground. After the operation is completed, the piston rod retracts, lifting the soil covering component 55 to a suspended state to avoid wear on the component. The soil covering component 55 adopts a hollow grid plate structure, which can evenly spread the surface soil on top of the fertilizer layer as the frame moves, completing the final soil covering process.
