Description

Technical Field

[0001] This utility model relates to the field of auxiliary agricultural machinery technology, and in particular to an auxiliary harvesting device for daylilies. Background Technology

[0002] As an important economic crop, the harvesting of daylilies is crucial to production efficiency and economic benefits. With the development of large-scale agriculture, traditional harvesting methods are unable to meet the growing production demands. Therefore, the development of efficient and convenient daylily harvesting auxiliary devices has become an important research direction in the field of agricultural machinery.

[0003] Currently, most daylily harvesting machines on the market use simple clamping or cutting structures. Some devices use a robotic arm operated manually to grab daylilies and a single cutting blade for harvesting. Others involve manually pushing a device with a simple collection basket, with manual assistance during the harvesting process. These devices mainly rely on manual operation and have a low degree of automation.

[0004] However, existing technologies have obvious drawbacks. The high degree of manual involvement results in low harvesting efficiency, making it difficult to meet the harvesting needs of large-scale daylily cultivation. Manual operation also leads to irregular harvesting processes, affecting the quality and integrity of daylilies. Furthermore, manual collection is tedious and prone to omissions, consuming a lot of manpower and resources without ensuring efficient and stable production. Therefore, an auxiliary daylily harvesting device is proposed to solve the above problems. Utility Model Content

The power component drives the top drive motors on both sides of the fixing platform to rotate the drive gear, which in turn drives the driven gear and the linkage gear. This causes the upper rack to move towards the center, and the clamping plate moves towards the center to clamp and fix the daylily stem. At the same time, the blades cut the stem, achieving the effect of quickly cutting and fixing the daylily, solving the problem of low efficiency in manual harvesting and improving harvesting efficiency. The drive gear has one end rotatably connected to the inner wall of the fixing platform. A symmetrical driven gear is rotatably connected to one side of the inside of the fixing platform.

[0015] As a further description of the above technical solution:

[0016] An electric actuator is provided between the limiting plates. The bottom of the electric actuator is fixedly connected to the inside of the fixed plate. A sliding plate is fixedly connected to the output end of the electric actuator. The two sides of the outer wall of the sliding plate are slidably connected to the side wall of the limiting plate.

At this time, the drive motor reverses, the clamping plate releases the stem, and the daylily falls into the collection frame by gravity, achieving the effect of automatic collection of daylilies. This solves the problems of tedious and easy omission of manual collection and improves collection efficiency. Attached Figure Description

Symmetrical limiting plates 18 are fixedly connected to the side walls of the fixed plates 6 by bolts.The limiting plate 18 is made of 304 stainless steel and is used to limit the movement range of the sliding plate 17. An electric actuator 16 is provided between the limiting plates 18. The outer shell of the electric actuator 16 is made of aluminum alloy and integrates a motor and a lead screw transmission mechanism, which is existing technology and will not be described in detail here. The bottom of the electric actuator 16 is fixedly connected to the inside of the fixed plate 6 by bolts. The output end of the electric actuator 16 is fixedly connected to the sliding plate 17 by a pin to provide the flipping power. The sliding plate 17 is stamped from 304 stainless steel. The two sides of the outer wall of the sliding plate 17 form a sliding fit with the guide grooves on the side walls of the limiting plate 18 to ensure smooth movement. A base 19 is fixedly connected to the side wall of the sliding plate 17. The base 19 is made of cast steel ZG270-500. Side plates 22 are fixedly connected to both sides of the outer wall of the fixed plate 6. The side plates 22 are made of Q235B steel plate. A... A connecting seat 20, machined from 45# steel, is used to connect the flipping plate 7 and the sliding plate 17. Both sides of the top outer wall of the base 19 are rotatably connected to the connecting seat 20 via pins. The side plates 22 have milled grooves 23 inside. Slider blocks 21 are fixedly connected to both sides of the outer wall of the connecting seat 20, slidingly connected within the grooves 23. The sliders 21 and grooves 23 form a sliding fit, ensuring the stability of the connecting seat 20 during rotation. A connecting platform 24 is fixedly connected to one side of the top of the side plate 22. Multiple shock-absorbing pads 25 are arranged between the connecting platform 24 and the flipping plate 7, distributed in an array. The bottom of the upper shock-absorbing pads 25 is fixedly connected to the bottom of the flipping plate 7, and the bottom of the lower shock-absorbing pads 25 is fixedly connected to the top of the connecting platform 24, used to absorb the impact force during the flipping process and reduce device vibration.

[0036] Working principle: When using this daylily harvesting auxiliary device, the staff pushes the collection frame 1 with the push handle 5. With the assistance of the walking wheels 4, the collection frame 1 moves between the ridges. At this time, the drive motor 9 on the top of the fixed platform 8 on both sides of the collection frame 1 drives the drive gear 10 to rotate. The rotation of the drive gear 10 drives the driven gear 12 on one side to rotate, and also drives the linkage gear 11 to rotate. The linkage gear 11 drives the driven gear 12 on the other side to rotate in the opposite direction, thereby driving the upper rack 13 to move towards the center, which in turn causes the clamping plate 14 to move towards the center. The displacement of the clamping plate 14 completes the clamping and fixing of the daylily stem, and drives the blade 15 to move towards the center to cut the daylily stem, thereby achieving the effect of quickly cutting and fixing the daylily.

[0037] After the daylily stems are fixed and cut, the electric push rod 16 pushes the sliding plate 17 to move upward. The displacement of the sliding plate 17 causes the base 19 to move as well. The displacement of the base 19 causes the connecting seat 20 to move, and at the same time, it causes the sliders 21 on both sides of the connecting seat 20 to slide in the grooves 23 inside the side plate 22. Under the restriction of the grooves 23, the connecting seat 20 rotates, which in turn drives the entire flipping plate 7 to rotate, so that the flipping plate 7 rotates from a vertical state to a horizontal state. At the same time, it also drives the daylily and the entire fixing platform 8 to rotate. At this time, the drive motor 9 reverses, causing the clamping plate 14 to release the daylily stems. The daylily slides into the collection frame 1 under the action of gravity, thus achieving the effect of automatically collecting the daylily.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
