Description

Technical Field

[0001] This invention relates to harvesting machine technology, specifically to a vibratory harvesting machine for honeysuckle in hilly areas. Background Technology

[0002] Honeysuckle, also known as Lonicera japonica, is a perennial medicinal plant belonging to the Lonicera genus of the Caprifoliaceae family. Its dried flower buds or newly opened flowers are a major traditional Chinese medicine, possessing both medicinal and economic value. Due to its strong adaptability and tolerance to drought and poor soil, it is widely cultivated in the hilly and mountainous areas of my country, making it an important economic crop for increasing agricultural income in hilly regions. The medicinal quality of honeysuckle is highly related to the timing of harvesting; it must be harvested promptly when the flower buds are full but not yet open to ensure the content of effective components. Currently, honeysuckle is still mainly harvested manually, with pickers plucking mature flower buds one by one, supplemented by simple handheld picking tools to preserve the integrity of the flower buds and control the quality of the harvest.

[0003] However, in the context of honeysuckle cultivation in hilly areas, the current honeysuckle harvesting is largely dependent on manual labor due to the dual limitations of terrain and operation methods. The rate of picking a single flower manually is limited, and the picking process requires long periods of bending over and raising arms, resulting in high labor intensity and being time-consuming and labor-intensive during the harvest season, directly restricting the overall harvesting efficiency. At the same time, the scattered plots and uneven terrain in hilly areas make it difficult for large-scale harvesting machinery suitable for plains areas to operate, making it impossible to replace manual labor with large-scale mechanized harvesting. During the peak harvesting period of flowering, there are often problems of labor shortage and untimely harvesting. Once the buds open, the quality drops significantly, further exacerbating the contradiction between harvesting efficiency and planting benefits, becoming the core bottleneck restricting the large-scale development of the honeysuckle industry in hilly areas.

[0012] Furthermore, the bottom end of the counterweight extends into the guide rail groove and is fixedly connected to a guide protrusion, and the guide rail groove and the guide protrusion are interlocked.

[0013] Furthermore, the harvesting vehicle has a fixed inner cavity inside, and several pressure sensors are installed at the bottom of the inner wall of the fixed inner cavity near the middle of the side. A sensing plate is movably installed at the top of the fixed inner cavity above the pressure sensors.

[0014] Furthermore, several grooves are provided on one side of the outer surface of the fixed top plate and the connecting plate.

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] As attached Figure 1 To be continued Figure 6 As shown:

[0035] Example 1:

[0036] The present invention provides a honeysuckle vibrating harvester for hilly areas, including a harvesting vehicle 1, with support wheels symmetrically arranged on both sides of the harvesting vehicle 1, a support base 2 arranged at the top center of the harvesting vehicle 1, a mechanical arm 3 rotatably installed inside the support base 2, and a bearing support 4 movably installed at the end of the mechanical arm 3.

[0037] An electric telescopic rod 5 is fixedly installed at one end of the bearing support 4. A fixed bracket 6 is fixedly connected to the output end of the upper surface of the electric telescopic rod 5. A fixed top plate 7 is fixedly installed on the upper surface of the fixed bracket 6. Several movable support rods 8 are rotatably installed on the outer surface of the fixed top plate 7. An elastic protective bag 9 is fixedly installed on one side of the inner wall of the multiple movable support rods 8.

[0038] Several guide grooves 10 are provided on the outer surface of the fixed bracket 6 at the corresponding positions of the movable support rod 8. A connecting plate 11 is fixedly installed at the end of the telescopic rod of the electric telescopic rod 5. Several connecting rods 12 are rotatably installed on the outer surface of the connecting plate 11 at the corresponding positions of the guide grooves 10. The top of the connecting rod 12 is rotatably connected to the bottom of the movable support rod 8.

[0039] Several grooves are provided on one side of the outer surface of the fixed top plate 7 and the connecting plate 11. The movable support rod 8 and the connecting rod 12 are rotatably installed inside the grooves through bearings. The fixed top plate 7 and the connecting plate 11 are coupled to the grooves.

[0040] The thickness of the connecting rod 12 at both ends is less than the distance between the front and rear ends of the inner wall of the guide groove 10. One side of the outer surface of the connecting rod 12 is located inside the guide groove 10, and the guide groove 10 and the connecting rod 12 are interlocked.

[0041] A vibration motor 13 is provided on one side of the outer surface of the fixed bracket 6. The vibration motor 13 is fixedly installed on the side of the fixed bracket 6. The output end of the vibration motor 13 is fixedly connected to the fixed bracket 6. A collection mechanism is provided on the outside of the fixed bracket 6 for collecting the honeysuckle picked from the elastic protective bag 9.

[0042] The collection mechanism includes a collection box 15, which is located on one side of the outer surface of the electric telescopic rod 5, opposite to the vibrating motor 13. The outer surfaces of the electric telescopic rod 5 and the collection box 15 are tied side by side with a binding strap 16.

[0043] The elastic protective bag 9 is a flexible and breathable cloth bag. The upper edge of the elastic protective bag 9 is fixedly connected to the inner wall of each movable support rod 8. The lower opening of the elastic protective bag 9 is connected to the conveying pipe 14, and the end of the conveying pipe 14 is connected to the inside of the collection box 15.

[0044] Working principle: First, the staff drives the picking vehicle 1 to the honeysuckle plant to be picked, adjusts the horizontal orientation of the mechanical arm 3 by rotating the support base 2, and then adjusts the pitch angle of the electric telescopic rod 5 by the bearing support 4, so that the fixed bracket 6 is aligned with the top of the honeysuckle plant, thus completing the position alignment before operation.

[0045] Next, the staff controls the telescopic rod of the electric telescopic rod 5 to extend downwards, causing the connecting plate 11 to move downwards synchronously. The connecting plate 11 drives each connecting rod 12 to slide downwards along the guide groove 10. The guide groove 10 limits the movement trajectory of the connecting rod 12, ensuring smooth movement without deviation. The top of the connecting rod 12 simultaneously pushes the movable support rod 8 to unfold outwards around the hinge point on the fixed top plate 7. The movable support rod 8 rotates in the groove through the bearing, and the opening and closing action is smooth without jamming. The elastic protective bag 9 opens synchronously with the movable support rod 8. The staff can adjust the extension stroke of the electric telescopic rod 5 according to the size of the plant crown and control the opening and closing angle of the movable support rod 8 to adapt to honeysuckle plants of different sizes.

[0046] Then, the staff operates the robotic arm 3 to slowly lower the fixed support 6, so that the open movable support 8 and the elastic protective bag 9 completely cover the honeysuckle plant, ensuring that all the honeysuckle branches are inside the elastic protective bag 9. Then, the staff starts the vibration motor 13, which generates high-frequency vibration and transmits it to the fixed support 6, and then through the movable support 8 to the elastic protective bag 9 and the honeysuckle branches. Mature honeysuckle buds fall off the branches due to the vibration and fall into the flexible elastic protective bag 9. The flexible material of the elastic protective bag 9 can buffer the collision of branches, reduce the damage of buds, and ensure the quality of harvest. The fallen buds slide down the inclined inner wall of the elastic protective bag 9 and gather in the bottom conveying pipe 14. Finally, they fall into the collection box 15 through the conveying pipe 14, completing the automatic collection of buds. The binding strap 16 securely binds the collection box 15 to the side of the electric telescopic rod 5 to prevent the collection box 15 from shaking and falling off during the operation.

[0047] Finally, after harvesting a single honeysuckle plant, the staff turns off the vibration motor 13, operates the robotic arm 3 to lift the fixed support 6, and then controls the electric telescopic rod 5 to retract the telescopic rod, driving the connecting plate 11 upward. The connecting rod 12 pulls the movable support rod 8 inward to reduce the space occupied by the equipment. The staff drives the harvesting vehicle 1 to move to the next plant and repeats the above process for continuous operation. When the buds in the collection box 15 are full, the staff can untie the binding strap 16 to remove the collection box 15 and empty it. The operation is convenient.

[0048] Example 2:

[0049] This embodiment is basically the same as the previous embodiment, except that a winding device 17 is provided at the center of the four sides of the upper surface of the picking vehicle 1. A connecting rope 19 is wound on the winding roller inside the winding device 17, and a counterweight 18 is installed on one end of the connecting rope 19 to the outside of the winding device 17.

[0050] The four sides of the outer surface of the picking vehicle 1 are provided with inclined surface structures. The outer surface of the picking vehicle 1 is symmetrically provided with guide rail grooves 20 near the bottom of the winding device 17. The counterweight 18 is placed above the guide rail grooves 20 on the inclined surface.

[0051] The bottom end of the counterweight 18 extends into the guide rail groove 20 and is fixedly connected to a guide protrusion. The guide rail groove 20 and the guide protrusion are interlocked.

[0052] The picking vehicle 1 has a fixed inner cavity 21 inside. Several pressure sensors 22 are installed at the bottom of the inner wall of the fixed inner cavity 21 near the middle of the side. A sensing plate 23 is movably installed at the top of the fixed inner cavity 21 above the pressure sensors 22.

[0053] Working principle: Based on Example 1, firstly, before the equipment operates each day, the staff will park the picking cart 1 on a level ground to complete the benchmark calibration; the pressure sensors 22 on each side of the fixed inner cavity 21 inside the picking cart 1 will collect the benchmark pressure value of the counterweight 18 at the corresponding position through the sensing plate 23 above, and the control unit will record the pressure benchmark range in the horizontal state to complete the initial calibration work.

[0054] Next, when the picking vehicle 1 enters the sloping hilly area, the vehicle body tilts to the side with the slope, and the counterweight pressure on each side sensor plate 23 changes accordingly; the pressure sensor 22 detects the pressure value of the corresponding side in real time and feeds it back to the control unit. The control unit calculates the tilt direction and approximate slope of the slope by the difference in pressure on each side, providing quantitative adjustment reference for the staff.

[0055] Then, based on the pressure data, the staff determines the side that needs counterweight compensation, starts the winding device 17 on the corresponding side, releases the connecting rope 19, and the connecting rope 19 drives the counterweight block 18 to slide along the guide rail groove 20 to the outside of the picking vehicle 1; the guide protrusion at the bottom of the counterweight block 18 is fitted into the guide rail groove 20 to limit the sliding direction of the counterweight block 18, prevent it from deviating and falling out, and ensure that the sliding process is smooth and stable; during the adjustment process, the pressure sensor 22 provides real-time feedback of the pressure value. After the pressure on each side returns to the reference balance range, the staff locks the winding roller of the winding device 17 and fixes the extension length of the connecting rope 19 to keep the counterweight block 18 in the adjusted position, thus completing the precise balance adjustment of the machine body's center of gravity.

[0056] Subsequently, when the harvesting vehicle 1 carries out vibratory harvesting operations on sloping ground, the counterweight 18, which is offset to the lower side, can counteract the tilting moment brought by the slope and the swaying reaction force generated by the operation of the vibrating motor 13. During the operation, the pressure sensor 22 continuously monitors the pressure changes on each side. When the vibration and swaying cause the center of gravity to shift beyond the safety threshold, the control unit will issue a timely warning. The staff can then fine-tune the position of the counterweight to prevent the machine from tipping over due to terrain undulations or vibration reaction forces. The staff can also adjust the position of the counterweights 18 on multiple sides simultaneously according to the actual terrain to ensure the stability of the harvesting vehicle 1 in complex hilly terrain and adapt to the harvesting needs of plots with different slopes.

[0057] Finally, when the day's work is completed or the plot needs to be moved, the staff starts the winding device 17 to retract the connecting rope 19, which drives the counterweight 18 to reset to the initial position along the guide rail groove 20, reducing the overall passage width of the equipment and facilitating transfer between narrow field ridges and plots; the pressure sensor 22 simultaneously detects the pressure value after reset, confirms that the counterweight has returned to the initial state, and completes the equipment reset.

[0058] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
