[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] According to the embodiments of the present utility model, a multifunctional carrot harvesting device, such as... Figure 1 As shown, the system includes a main housing 10, a photovoltaic following mechanism 20, a walking mechanism 30, a seedling supporting mechanism 40, a conveying mechanism 50, a soil sieving and collecting mechanism 60, a soil loosening mechanism 70, a lifting and telescopic mechanism 80, a storage battery 90, and a control relay 100. A connection position is provided on one side of the main housing 10, and a fixing frame 11 is provided on the main housing 10. The photovoltaic following mechanism 20 is located on the top of the main housing 10. The walking mechanism 30 is located at the bottom of the main housing 10. The first end of the seedling supporting mechanism 40 is rotatably mounted on the main housing 10, and the second end of the seedling supporting mechanism 40 extends to the main housing 10. The outer lower part; the conveying mechanism 50 is located inside the main housing 10; the soil sieving and collecting mechanism 60 is located inside the lower end of the main housing 10, with one end of the soil sieving and collecting mechanism 60 meshing with one end of the conveying mechanism 50; one end of the soil loosening mechanism 70 is rotatably fitted onto the fixed frame 11, and the other end of the soil loosening mechanism 70 is connected to the connecting position on the main housing 10; one end of the lifting telescopic mechanism 80 is located at the top of the main housing 10, and the other end of the lifting telescopic mechanism 80 is connected to the second end of the seedling support mechanism 40; the storage battery 90 is located in the main housing 10; the control relay 100 is located in the main housing 10. In the main housing 10, the input terminal of the control relay 100 is connected to the battery 90, and the output terminal of the control relay 100 is connected to the photovoltaic following mechanism 20, the walking mechanism 30, the seedling supporting mechanism 40, the soil sieving and collecting mechanism 60, the soil loosening mechanism 70, and the lifting telescopic mechanism 80. The photovoltaic following mechanism 20 converts sunlight into electrical energy by rotating in the direction of sunlight and transmits it to the battery 90. The walking mechanism 30 moves the main housing 10 and causes the soil loosening mechanism 70 to turn over the soil. The seedling supporting mechanism 40 approaches the field via the lifting telescopic mechanism 80, and the seedling supporting mechanism 40... The carrots are picked up and moved to the conveyor mechanism 50, and then enter the soil sieving and collecting mechanism 60. Before this device, the processes of loosening the soil in the field, pulling the carrots out of the field, and transporting the carrots to the collection point all required manual operation, which was too labor-intensive and inefficient. This multi-functional carrot harvesting device integrates multiple functions and covers these processes, making carrot harvesting more efficient and standardized. At the same time, the separate control and remote control of multiple mechanisms can be achieved by controlling the relay 100, resulting in a high degree of automation.

[0024] In specific implementation, such as Figure 1 and Figure 2As shown, the photovoltaic following mechanism 20 includes a connecting base 21, a first steering mechanism 22, a second steering mechanism 23, a photovoltaic panel 24, and photosensors 25. The connecting base 21 is located on the top of the main housing 10. The first steering mechanism 22 is mounted on the connecting base 21 and connected to the control relay 100. The second steering mechanism 23 is mounted on the first steering mechanism 22 and connected to the control relay 100. The photovoltaic panel 24 is mounted on the second steering mechanism 23. Multiple photosensors 25 are mounted on the connecting base 21 and connected to the first steering mechanism 22, the second steering mechanism 23, and the control relay 100. The multiple photosensors 25 are adjusted by the angle of sunlight. The first steering mechanism 22 and the second steering mechanism 23 are configured to align the photovoltaic panel 24 with sunlight. The first steering mechanism 22 adjusts the lateral rotation angle of the photovoltaic panel 24, while the second steering mechanism 23 adjusts the longitudinal rotation angle of the photovoltaic panel 24, which is also its tilt angle. These two converters allow the photovoltaic panel 24 to be better aligned with the direction of sunlight. The first steering mechanism 22 and the second steering mechanism 23 can achieve the steering effect in various ways. For example, the first steering mechanism 22 can be a servo motor, the main body of the second steering mechanism 23 can be connected to the rotating shaft of the servo motor, and the rotating part of the second steering mechanism 23 can also use a servo motor. The photovoltaic panel 24 is connected to its rotating shaft, thus achieving the above effect.

[0025] In specific implementation, such as Figure 1 and Figure 3 As shown, the walking mechanism 30 includes a connecting plate 31, a main body 32, track assemblies 33, and a drive motor 34; there are two connecting plates 31, both of which are located at the bottom of the main housing 10; the main body 32 is connected to the two connecting plates 31; there are two track assemblies 33, which are rotatably mounted on both sides of the main body 32; there are two drive motors 34, which are mounted on the two track assemblies 33 and are connected to the control relay 100; the drive motors 34 drive the two track assemblies 33 to rotate so that the multi-functional carrot harvesting device can move. The use of track assemblies 33 is due to the fact that the working environment is mainly in the field, and the use of tracks makes walking more flexible in muddy terrain.

[0026] In specific implementation, such as Figure 5As shown, the seedling support mechanism 40 includes a main board 41, a gripping and conveying assembly 42, and a cutting blade 43. The first end of the main board 41 is rotatably mounted on the main housing 10, and the second end of the main board 41 has a connecting interface. The gripping and conveying assembly 42 is rotatably mounted on the main board 41 and connected to the control relay 100. The cutting blade 43 is rotatably mounted on the main board 41 and close to the first end of the main board 41 and connected to the control relay 100. The gripping and conveying assembly 42 grips the carrot from the connecting interface, cuts it with the cutting blade 43, and then conveys it to the conveying mechanism 50. The cutting blade 43 can separate the main body and stems and leaves of the carrot, and the conveying mechanism 50 can collect them separately, eliminating the need for manual sorting.

[0027] In specific implementation, such as Figure 1 and Figure 4 As shown, the conveying mechanism 50 includes fixed rotating rods 51, conveying sleeves 52, conveyor belts 53, a main drive shaft 54, a secondary drive shaft 55, and a transmission belt 56. Multiple fixed rotating rods 51 are present, with their ends rotatably mounted on corresponding side walls inside the main housing 10. Multiple conveying sleeves 52 are present, each mounted on one of the fixed rotating rods 51. Two conveyor belts 53 are present, each mounted on one of the multiple conveying sleeves 52. The main drive shaft 54 ​​is mounted on one of the fixed rotating rods 51 and has a toothed structure. Multiple secondary drive shafts 55 are present. The auxiliary drive shafts 55 are respectively mounted on multiple fixed rotating rods 51; there are multiple drive belts 56, which are respectively sleeved on the main drive shaft 54 ​​and multiple auxiliary drive shafts 55; one end of the soil sieving and collecting mechanism 60 meshes with the main drive shaft 54 ​​and drives it to rotate. The rotation of the main drive shaft 54 ​​drives the multiple auxiliary drive shafts 55 to rotate through the multiple drive belts 56, thereby causing the multiple fixed rotating rods 51 to rotate. The rotation of the multiple fixed rotating rods 51 drives the multiple conveying sleeves 52 to rotate, thereby causing the two conveyor belts 53 to roll. The two conveyor belts 53 continuously roll and separate the carrot body and stems and leaves and send them to their respective collection points.

[0028] In specific implementation, such as Figure 1As shown, the soil collection mechanism 60 includes a sleeve 61, a spiral shaft 62, a rotary motor 63, a steering gear 64, a collection box 65, and a capacity detection alarm 66. The sleeve 61 is located inside the lower end of the main housing 10, with a receiving port on its upper part. Two shaft holes are respectively opened on the first and second side walls of the sleeve 61, and a discharge port is opened on the second side wall. The first and second ends of the spiral shaft 62 are rotatably mounted in the sleeve 61, passing through the two shaft holes respectively. The spiral shaft 62 is spiral-shaped. The rotary motor 63 is located inside the main housing 10 and is connected to the control relay 100 and the second end of the spiral shaft 62. The steering gear 64 is located at the first end of the spiral shaft 62 and meshes with the main drive shaft 54. The collection box 65 is located inside the lower end of the main housing 10. The collection box 65 has a collection port that is connected to the discharge port on the sleeve 61. The capacity detection alarm 66 is located inside the collection box 65 and is connected to the control relay 100. The rotary motor 63 drives the spiral shaft 62 to rotate and drives the main drive shaft 54 ​​to rotate through the steering gear 64. The carrots harvested from the field have a lot of soil attached to them. The spiral shaft 62 drives the rotation and rolls in the sleeve 61, which can shake off most of the soil, thereby reducing the subsequent manual cleaning process. At the same time, the capacity detection alarm 66 inside the collection box 65 can monitor the capacity of the collection box 65 in real time to avoid the collection box 65 from continuing to collect carrots when it is full, which would cause a malfunction. This also reduces the maintenance frequency of the device.

[0029] In specific implementation, such as Figure 1 and Figure 5 As shown, the soil loosening mechanism 70 includes a soil loosening shovel assembly 71, a distance sensor 72, and a push rod 73. The soil loosening shovel assembly 71 is rotatably mounted on the fixed frame 11. The distance sensor 72 is located at the connection position to detect the distance between the main housing 10 and the field. The distance sensor 72 is connected to the control relay 100. The push rod 73 is mounted on the distance sensor 72 and is rotatably connected to the middle of the soil loosening shovel assembly 71. The push rod 73 is used to receive data transmitted by the distance sensor 72 to adjust the angle of the soil loosening shovel assembly 71, so that the soil loosening shovel assembly 71 can better follow the terrain of the field to loosen the field and make the carrots easier to pick up.

[0030] In specific implementation, such as Figure 5As shown, the lifting telescopic mechanism 80 includes a mounting plate 81, a slide rail 82, a slider 83, a first gear 84, a connecting block 85, a second gear 86, a third gear 87, a gear motor 88, and a fourth gear 89.

The slider 83 is slidably mounted on the slide rail 82, with its first end connected to the outer sides of the interface of the main housing 41, and its second end having a wheel axle hole. The first gear 84 is rotatably mounted on the wheel axle hole. The first end of the connecting block 85 is rotatably mounted on the wheel axle hole. The second gear 86 is rotatably mounted on the second end of the connecting block 85, with its outer side meshing with the outer side of the first gear 84. The middle part of the third gear 87 is located on the lower surface of the second gear 86. The gear motor 88 is located on the mounting plate 81, a slide rail 82, a slider 83, a first gear 84, a connecting block 85, a second gear 86, a third gear 87, a gear motor 88, and a fourth gear 89. The device is mounted on plate 81 and connected to control relay 100; the fourth gear 89 is rotatably mounted on gear motor 88, and the outer side of the fourth gear 89 meshes with the outer side of the third gear 87; wherein, the gear motor 88 drives the fourth gear 89 to rotate, so that the third gear 87 rotates circumferentially along the outer side of the fourth gear 89 and drives the second gear 86 to move along the rotation direction of the fourth gear 89. The second gear 86 moves, driving the connecting block 85 and the first gear 84 to move, so that the slider 83 slides on the slide rail 82. When the slider 83 is at the front end of the track range, the main body 41 can be lowered to the lowest position. When the slider 83 is at the rear end of the track range, the main body 41 can be raised to the highest point, thereby adapting to the terrain of the field and the height of the carrots, making it more suitable for harvesting carrots of various varieties and sizes.
