Description

Technical Field

[0001] This utility model relates to the field of strawberry harvesting technology, and in particular to a strawberry seedling harvester. Background Technology

[0002] Strawberries, a nutritious and healthy fruit, contain ellagic acid, which has significant anti-cancer effects. They are also highly adaptable and easy to cultivate. However, the harvesting of bare-root strawberry seedlings currently relies mainly on manual labor, leading to high labor intensity, low efficiency, and severely hindering the large-scale development of the strawberry seedling industry. Overseas agriculture is largely based on large-scale farms, resulting in bulky and costly strawberry seedling harvesting machinery unsuitable for my country's small-scale, dispersed strawberry seedling propagation model.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1 to 5 This utility model provides a strawberry seedling harvester, comprising: tractor; The connecting frame 10 is installed at the front end of the tractor via the connecting rod 11. The connecting frame 10 is equipped with a cutting device for cutting the runners of the strawberry seedlings. The frame is mounted on the rear end of the tractor via a three-point suspension device. Multiple ground wheels 26 are installed on the frame. An excavating device is installed at the front end of the frame, and a collection box 25 is installed at the rear end of the frame. A conveying and collecting device is installed between the excavating device and the collection box 25. The conveying and collecting device includes a primary conveying chain 21 and a secondary conveying chain 24. The feeding end of the primary conveying chain 21 is located below the discharging end of the secondary conveying chain 24, forming a two-stage stepped conveying structure. A drive connection device is used to provide power to the conveying and collecting device.

[0020] The two-stage tiered conveyor chain layout enables stable and low-damage transport of strawberry seedlings. The overall structure is compact, easy to connect with tractors, and highly adaptable. It effectively solves the problems of unsuitability, low efficiency, and high seedling damage rate of existing harvesting equipment. Through integrated design, the functions of cutting, digging, conveying, and collecting are integrated into one, which significantly improves the harvesting efficiency of strawberry seedlings, reduces labor costs, and ensures the integrity and quality of strawberry seedlings.

[0021] In one embodiment of this utility model, the cutting device includes: Mounting frame 2, with a divider 1 at the front end, and a cutting blade 32 and a drive motor 33 inside the divider 1; Height sensor 3 is mounted on mounting bracket 2; The electric push rod 4 is hinged to the mounting bracket 2 and the connecting bracket 10 via a connecting mechanism, and the electric push rod is connected to the height sensor signal.

[0022] Furthermore, there is at least one divider 1, and multiple dividers 1 are arranged side by side, each divider 1 being independently equipped with a cutting blade 32 and a drive motor 33.

[0023] By cooperating with the height sensor 3 and the electric push rod 4, the height of the divider 1 is automatically adjusted, ensuring that the cutting device can adapt to different terrains and crop heights, improving cutting accuracy and operational stability. The divider 1 design in the cutting device effectively separates the strawberry seedling leaves, ensuring that the cutting blade 32 can accurately cut the runners, reducing miscutting and missed cutting, and improving cutting efficiency and accuracy.

[0024] In one embodiment of this utility model, the connecting mechanism includes: A horizontal fixed frame 6 is rotatably connected to a connecting frame 10 via a rotating frame 9. The horizontal fixed frame 6 is fixedly connected to a mounting frame 2. A fixed plate 5 is fixedly connected to the horizontal fixed frame 6. An electric push rod 4 is hinged to the fixed plate 5. The output end of the electric push rod 4 is hinged to the horizontal fixed frame 6. An electrical box 7 connected to the electric push rod 4 is provided on the horizontal fixed frame 6. The support rod 8 is fixedly connected to the connecting frame 10, and the support rod 8 is hinged to the fixed end of the electric push rod 4.

[0025] The connection mechanism, through the ingenious design of the horizontal fixed frame 6, the rotating frame 9 and the support rod 8, achieves a stable hinge connection between the electric push rod 4 and the mounting frame 2 and the connecting frame 10, ensuring the accurate transmission of the height sensor 3 signal and the stable operation of the electric push rod 4, thereby improving the reliability and durability of the equipment.

[0026] In one embodiment of the present invention, the conveying and collecting device further includes a soil pressing roller 22, which is disposed above the primary conveying chain 21, and the rotation direction of the soil pressing roller 22 is opposite to that of the primary conveying chain 21.

[0027] The soil compaction roller 22 effectively crushes the soil clumps adhering to the strawberry seedlings during transportation, reducing subsequent cleaning work and preventing damage to the strawberry seedlings from the soil clumps, thus improving the harvest quality.

[0028] In one embodiment of the present invention, the conveying and collecting device further includes a baffle plate 27, which is disposed behind the top of the primary conveyor chain 21 and above the top of the secondary conveyor chain 24.

[0029] The baffle plate 27 can effectively prevent strawberry seedlings from piling up or falling when transitioning from the end of the primary conveyor chain 21 to the secondary conveyor chain 24, ensuring smooth material transfer.

[0030] In one embodiment of the present invention, the conveying and collecting device further includes a second auxiliary roller and a third auxiliary roller. The second auxiliary roller and the third auxiliary roller are arranged in the area between the top rear of the first-stage conveyor chain 21, the front side of the baffle plate 27, and the top of the second-stage conveyor chain 24. The second auxiliary roller and the third auxiliary roller rotate in opposite directions, forming a pair of rollers 23.

[0031] Furthermore, sprockets with the same number of teeth are installed on the shaft ends of the second and third auxiliary rollers. Then, a closed-loop chain is used to simultaneously pass around these two sprockets. The chain is wound around the sprockets in an S-shape, which can realize the opposite rotation of the two rollers. This chain is engaged with the second gearbox 18 for transmission.

[0032] The structure of roller 23 performs secondary compression and crushing of the soil around the roots of strawberry seedlings, further improving the soil separation effect and ensuring that the seedlings are clean and intact.

[0033] In one embodiment of this utility model, the drive connection device includes: The first gearbox 12 is mounted on the tractor. The first gearbox 12 is connected to the power output shaft 13. The power of the first gearbox 12 comes from the tractor. This is a conventional technical means in the field and will not be described in detail here. The second gearbox 18 is mounted on the frame via the traction frame 17 and is connected to the power output shaft 13 via the universal joint 16. The second gearbox 18 has a first output end and a second output end. The first output end controls the rotation of the primary conveyor chain 21 and the secondary conveyor chain 24 via the belt 19, and the second output end controls the rotation of the second auxiliary roller and the third auxiliary roller.

[0034] The power from the tractor is transmitted to the second gearbox 18 through the universal drive shaft 16. After reduction and torque increase, a power output shaft is led out from the first output end of the second gearbox 18. This power output shaft drives the primary conveyor chain 21 and the secondary conveyor chain 24 simultaneously through the belt 19, chain, and sprocket.

[0035] Through the rational design of the first gearbox 12 and the second gearbox 18, the drive connection device achieves precise control of the primary conveyor chain 21, the secondary conveyor chain 24 and the auxiliary rollers, ensuring coordinated operation between the components and improving the overall performance and efficiency of the equipment.

[0036] Furthermore, the second gearbox 18 is also equipped with a third output end, which is used to drive the soil compaction roller 22 to rotate.

[0037] In one embodiment of this utility model, the excavating device includes: The excavation plate 28 is installed at an angle at the bottom of the front end of the frame; Digging teeth 29 are located at the front end of the digging plate 28.

[0038] The design of the digging plate 28 and digging teeth 29 allows for easy insertion into the soil to dig up strawberry seedlings, reducing resistance during the digging process, improving digging efficiency and accuracy, and avoiding excessive damage to the strawberry seedlings.

[0039] In one embodiment of this utility model, the three-point suspension device includes: The fixed support 14 and a pair of lifting rods 15 are fixedly connected to the tractor; The upper pull rod 30 and a pair of lower pull rods 31 are fixedly connected to the frame. The upper pull rod 30 and the pair of lower pull rods 31 are used to connect to the fixed support 14 and a pair of lifting rods 15.

[0040] The three-point suspension design ensures a stable connection between the frame and the tractor, improving the stability and safety of the equipment during operation, while also facilitating quick installation and disassembly.

[0041] In one embodiment of this utility model, it further includes: A vibrating plate is installed between the excavating device and the primary conveyor chain 21; The crank double rocker mechanism 20 is mounted on the frame and is connected to the drive connection device and the vibration plate. The second gearbox 18 is also provided with an output end for driving the crank double rocker mechanism 20.

[0042] The combination of the vibrating plate and the crank double rocker mechanism 20 can immediately break up and separate the soil clods after excavation, reduce the load on the subsequent conveyor chain, and improve the overall harvesting efficiency.

[0043] Working principle: First, the connecting rod 11 is fixedly installed at the front of the tractor. The upper pull rod 30 and the two lower pull rods 31 are respectively connected to the fixed support 14 at the rear of the tractor and the two lifting rods 15. The two ends of the universal joint 16 are respectively installed at the rear end of the power output shaft 13 and the front end of the second gearbox 18, thus completing the installation of the three-point suspension. When the tractor is started, as the tractor moves forward, the height sensor 3 transmits a signal to the electric push rod 4. The electric push rod 4 controls the height of the divider 1 through the support rod 8. The divider 1 pushes the leaves of the strawberry seedlings to both sides, and the cutting blade 32 inside the divider 1 begins to cut the runner structure of the strawberry seedlings. As the tractor moves forward, the excavating device connected to the rear of the tractor begins to work. The second gearbox 18 transmits power to the belt 19, thereby driving the conveyor chain to work. The excavating plate 28 and the excavating teeth 29 insert into the soil and push the strawberry seedlings onto the vibrating plate controlled by the crank double rocker mechanism 20 to separate large clumps of soil first. Then, the soil is conveyed to the primary conveyor chain 21. Behind the primary conveyor chain 21, there is a soil-pressing roller 22 to crush the soil. Then, the soil enters the secondary conveyor chain 24. The secondary conveyor chain 24 further crushes the soil through two rollers 23 rotating in opposite directions. Finally, the strawberry seedlings are conveyed into the collection box 25.
