Description

Technical Field

[0001] This invention relates to the field of agricultural harvesting equipment technology, and in particular to an artemisia harvester with an adjustable harvesting platform height. Background Technology

[0002] Artemisia harvesters are agricultural machines specifically designed for harvesting Artemisia argyi and other Chinese medicinal herbs. They aim to solve the problems of low efficiency and high cost associated with manual harvesting. They have functions such as cutting and laying out Artemisia argyi neatly with a conveyor belt. Some models also have a defoliation function, which can be used to directly collect Artemisia argyi leaves. The models include push-type, self-propelled, and tractor-mounted types, which are suitable for different terrains such as plains and hills. They are key equipment for large-scale cultivation of Artemisia argyi.

[0003] In practical applications, because artemisia is often accompanied by vine-like weeds during its growth, traditional artemisia cutters tend to pull on these weeds during cutting. This pulling force is transmitted through the vines to the roots of the artemisia, potentially causing the roots and stems to loosen, tear, or even uproot the entire plant, severely impacting its regeneration capacity and yield the following year. Therefore, providing an artemisia harvester with an adjustable harvesting platform height is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] One objective of this invention is to provide an artemisia harvester with an adjustable harvesting platform height to solve the aforementioned technical problems. The technical solution of this invention is as follows: According to an embodiment of the present invention, an artemisia harvester with an adjustable harvesting platform height includes a harvester body and a control console and adjustment assembly located on the harvester body. One end of the adjustment assembly is fixedly connected to a collection box. The harvester also includes: a cutting mechanism located on one side of the collection box; the cutting mechanism includes a mounting frame with a fixing groove; a moving blade assembly slidably connected within the fixing groove; a fixed blade assembly and multiple blade guards fixedly connected to the mounting frame by bolts; each blade guard having an anti-entanglement component; the moving blade assembly including a blade bar and multiple moving blades riveted to the blade bar; the fixed blade assembly including multiple parallel fixed blades, which are alternately distributed with the blade guards; the fixed blades located on the top outer wall of the moving blades; the moving blades slidably connected inside the blade guards; two fixing frames on one outer wall of the collection box; and a throwing mechanism located on top of the multiple blade guards; and a driving mechanism located on one side of the cutting mechanism.

[0005] Furthermore, the plurality of fixed blades are arranged in a comb-like pattern. Each fixed blade has a triangular pyramid structure, with its two lower edges serving as cutting edges facing downwards. The movable blade has a triangular structure, with its upper inclined surface serving as a cutting edge facing upwards. The cutting edges of the movable blade and the fixed blades form a shearing engagement.

[0006] By adopting the above technical solution, the two blades on both sides of the triangular fixed blade can help guide the stem towards the middle to prevent slippage, and the moving blade can cooperate with the two blades on both sides of the fixed blade to effectively cut during the reciprocating stroke, thereby improving the cutting efficiency.

[0007] Furthermore, the anti-entanglement component includes multiple directional plates, which are fixedly connected to one outer wall of the blade guard by bolts. The directional plates have an arrow-shaped structure, and two auxiliary blades are provided on both outer walls of the directional plates.

[0008] By adopting the above technical solution, during the process of picking up the vines, the auxiliary blade pre-cuts the vines, chopping the long vines into small sections, so that they lose their ability to entangle. Compared with traditional harvesters, where the blades are easily entangled and clogged when encountering vines and weeds, requiring frequent stops for cleaning, this solution effectively avoids entanglement, greatly reduces downtime caused by blockage, and improves continuous operation capability.

[0009] Furthermore, the throwing mechanism includes multiple guide plates, and a fixing frame is provided between the guide plate and the blade guard. The guide plate is fixedly connected to the blade guard through the fixing frame. Multiple connecting frames are fixedly connected to both outer walls of the guide plate. A horizontal shaft is provided between two adjacent connecting frames. A grass-pulling wheel is fixedly connected to the horizontal shaft. The two ends of the horizontal shaft are connected to the two connecting frames through one-way bearings.

[0010] By adopting the above technical solution, when the vine fragments are pushed upwards by the machine's forward thrust and airflow to contact the teeth of the weeding wheel, the vines generate an upward frictional force on the weeding wheel. This frictional force causes the weeding wheel to rotate. When the weeding wheel rotates, its teeth grab the vine fragments and throw them backwards and upwards, causing them to leave the cutting area. The one-way bearing prevents the weeding wheel from pressing the vines downwards back into the cutting area, ensuring that the vines are always thrown upwards and backwards.

[0011] The beneficial effects of this invention are: Compared to traditional mugwort harvesters, this invention allows for rapid adjustment of the cutting platform height, making it suitable for various field conditions. It also prevents vines from entangled in the blades and pulling on the roots during harvesting, reducing damage to the mugwort rhizomes and improving cutting efficiency. Specifically, as the harvester moves forward, the vines mixed with the mugwort plants are first physically separated from the plants by a dividing plate. The upright, thicker stems of the mugwort slide past the sides of the dividing plate and continue into the shearing area, while the creeping, slender, and easily entangled vines are lifted by the tip of the dividing plate and guided upwards along its upper surface. During this lifting process, auxiliary blades on the outer walls of the dividing plate pre-cut the vines. The vines are chopped into small pieces. These chopped pieces are scattered to the sides or upwards by the airflow and vibration of the machine, preventing them from directly entering the cutting area below. Once the mugwort stems enter the cutting area, they are clamped between the lower edge of the fixed blade and the upper edge of the moving blade. The drive mechanism then moves multiple moving blades in a linear reciprocating motion. The blades of the moving blades and the fixed blades engage in a shearing action, cutting the mugwort stems. Once cut, the mugwort loses its support and, under the combined force of gravity and the machine's forward thrust, tilts backwards. The tilted mugwort falls directly onto a conveyor belt installed inside the collection box, and finally, under gravity, settles at the bottom of the collection box, achieving orderly accumulation.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 An adjustable-height artemisia harvester includes a harvester body 1, a control console 2 and an adjustment assembly 3 located on the harvester body 1, and a collection box 4 fixedly connected to one end of the adjustment assembly 3. The harvester also includes: a cutting mechanism located on one side of the collection box 4, comprising a mounting frame 11 with a fixing groove 31, a movable blade assembly 19 slidably connected within the fixing groove 31, a fixed blade assembly 18 and multiple blade guards 7 fixedly connected to the mounting frame 11 by bolts, and an anti-winding component on each blade guard 7; the movable blade assembly 19 includes a blade bar 9 and multiple movable blades riveted to the blade bar 9; the fixed blade assembly 18 includes multiple parallel fixed blades, which are alternately distributed with the blade guards 7; the fixed blades are located on the top outer wall of the movable blades, and the movable blades are slidably connected inside the blade guards 7; two fixing frames 10 are provided on one outer wall of the collection box 4, and the blade bar 9 is slidably connected to the fixing frames 10; a throwing mechanism located on top of the multiple blade guards 7; and a drive mechanism located on one side of the cutting mechanism.

[0023] The device comprises multiple fixed blades arranged in a comb-like pattern. Each fixed blade has a triangular pyramid structure with its two lower edges serving as cutting edges facing downwards. The moving blade has a triangular structure with its upper inclined surface serving as the cutting edge facing upwards. The cutting edges of the moving blade and the fixed blades form a shearing engagement. In practice, the apex angle of the triangle can be set to 30-45 degrees to allow the cutting edges to gradually enter rather than suddenly impact, reducing pressure damage to the stem. The two sides of the triangle can help guide the stem towards the center to prevent slippage. The moving blade can effectively cut in conjunction with the fixed blade during its reciprocating stroke, improving cutting efficiency.

[0024] In practical use, a guide block 20 is provided at one end of the fixed blade near the forward direction of the cutting machine body 1. The guide block 20 has a conical structure, which can effectively divert the oncoming mugwort plants and reduce the impact resistance between the guide block 20 and the mugwort. In addition, the surface of the conical guide block 20 is smooth and has no sharp edges. During the process of guiding and straightening the mugwort stems, it will not scratch or squeeze the stem surface, thus ensuring the quality of the harvested mugwort.

[0025] Specifically, the anti-entanglement component includes multiple directional plates 5, which are fixedly connected to one outer wall of the blade guard 7 by bolts. The directional plates 5 have an arrow-shaped structure, and two auxiliary blades 12 are provided on both outer walls of the directional plates 5. During the process of lifting the vines, the auxiliary blades 12 pre-cut the vines, chopping the long vines into small sections, so that they completely lose their entanglement ability. Compared with traditional harvesters, where the blades are easily entangled and blocked when encountering vines and weeds, requiring frequent shutdowns for cleaning, this solution effectively avoids entanglement, greatly reduces downtime caused by blockage, and improves continuous operation capability.

[0026] In practical use, the dividing plate 5 can be made of stainless steel plate with Teflon coating, thereby reducing the adhesion coefficient of vines.

[0027] The collection box 4 is equipped with a conveyor belt 6 inside. The conveyor belt 6 is used to transport the cut mugwort into the collection box 4. The height of the conveyor belt 6 is lower than the height of the mounting frame 11. The cut mugwort stems fall backward onto the upper surface of the conveyor belt 6 under the action of their own weight and the forward thrust of the machine, and will not accumulate on the cutting surface, thus avoiding the mugwort from being stuck between the fixed blades and causing blockage. Then the conveyor belt 6 transports the cut mugwort stems to the bottom of the collection box 4, so as to achieve orderly accumulation.

[0028] In a preferred embodiment, the conveyor belt 6 is driven by a drive motor via a sprocket.

[0029] In the specific implementation process, the adjustment component 3 includes two fixed blocks 17, which are located on the outer walls of the two sides of the collection box 4. The bottom of the control console 2 is equipped with two electric telescopic rods, and the movable ends of the electric telescopic rods are fixedly connected to the fixed blocks 17. The two electric telescopic rods are controlled to extend and retract synchronously through the control console 2, which drives the collection box 4 and the cutting mechanism fixedly connected to it to rise and fall as a whole. The gap between the cutting platform and the ground can be quickly and accurately adjusted according to the different growth heights of Artemisia argyi, such as the first and second crops.

[0030] In a preferred embodiment, the electric telescopic rod in the adjusting assembly 3 can be replaced by a hydraulic or lead screw solution.

[0031] Specifically, before the operation begins, the operator activates the adjustment component 3 via the control console 2. The movable end of the electric telescopic rod is fixedly connected to the fixed blocks 17 on both sides of the collection box 4. Through the telescopic movement, the collection box 4 and the cutting mechanism fixedly connected to it are raised and lowered as a whole, so that the ground clearance of the cutting mechanism matches the current growth height of the mugwort, realizing the rapid adjustment of the harvesting platform height. When the harvester body 1 moves forward, the vines and mugwort plants mixed in with the mugwort first come into contact with the dividing plate 5. Since the dividing plate 5 is arrow-shaped with the tip pointing forward, the mugwort with thicker upright stems slides past the sides of the dividing plate 5 and continues to move backward. In the shearing area, the creeping, soft, and easily entangled vines are lifted by the tip of the dividing plate 5 and guided upwards along the inclined surface of the dividing plate 5. During this lifting process, auxiliary blades 12 on both sides of the outer wall of the dividing plate 5 pre-cut the vines, breaking them into small segments. These shredded segments are scattered to the sides or upwards by the airflow and vibration of the machine, preventing them from directly entering the shearing area below. After being separated by the dividing plate 5, the mugwort plant continues to move backwards, first contacting the guide block 20 installed at the front end of the fixed blade. The guide block 20 guides and straightens the upright mugwort stem, making it... The mugwort stem accurately enters the shearing zone between the moving and fixed blades. After entering the shearing zone, the stem is clamped between the lower edge of the fixed blade and the upper edge of the moving blade. Then, the drive mechanism drives the blade holder 9 to perform high-speed reciprocating linear motion within the fixed frame 10. Since multiple moving blades are riveted and fixed to the blade holder 9, all moving blades move synchronously. When the moving blades slide inside the blade guard 7, the blades of the moving blades and the blades of the fixed blades form a shearing engagement, similar to the working principle of scissors, cleanly cutting the mugwort stem from above the root. After being cut, the mugwort loses its support from below and is then subjected to gravity and machine force. Under the combined action of forward thrust, the mugwort tilts backward, falling directly onto the conveyor belt 6 installed inside the collection box 4. Finally, under the action of gravity, it falls to the bottom of the collection box 4, achieving orderly accumulation. After the moving blade assembly 19 completes one cutting stroke, it returns to the starting position under the drive mechanism, ready for the next cut. As the machine moves forward continuously, the above process is repeated continuously, realizing continuous harvesting of mugwort. This device can quickly adjust the height of the cutting platform, is suitable for various field conditions, and can avoid the vines from wrapping around the blades and pulling on the roots of the mugwort during harvesting, reducing damage to the roots and stems of the mugwort and improving cutting efficiency.

[0032] Please refer to Figure 1 , Figure 2 and Figure 4In a preferred embodiment, the throwing mechanism includes multiple guide plates 14, with a fixing frame 13 between the guide plates 14 and the blade guard 7. The guide plates 14 are fixedly connected to the blade guard 7 through the fixing frame 13. Multiple connecting frames 15 are fixedly connected to the outer walls on both sides of the guide plates 14. A horizontal shaft is provided between two adjacent connecting frames 15, and a grass-removing wheel 16 is fixedly connected to the horizontal shaft. The two ends of the horizontal shaft are connected to the two connecting frames 15 through one-way bearings.

[0033] The guide plate 14 is inclined upward, and one end of the guide plate 14 extends above the collection box 4.

[0034] Specifically, the weed-removing wheel 16 is a toothed rubber wheel. When the vine fragments are pushed forward by the machine's thrust and airflow and come into contact with the teeth of the weed-removing wheel 16 from bottom to top, the vines generate an upward frictional force on the weed-removing wheel 16. This frictional force causes the weed-removing wheel 16 to rotate. When the weed-removing wheel 16 rotates, its teeth grab the vine fragments and throw them backward and upward, causing them to leave the cutting area. Since the weed-removing wheel 16 is connected to the connecting frame 15 through a one-way bearing, the one-way bearing only allows the horizontal axis and the weed-removing wheel 16 to rotate backward and upward. Viewed from the right side, that is, in a clockwise direction, if the vine fragments come into contact with the weed-removing wheel 16 from above in the opposite direction, the one-way bearing will lock, preventing the weed-removing wheel 16 from rotating in the opposite direction. This prevents the weed-removing wheel 16 from pressing the vines downward back into the cutting area, ensuring that the vines are always thrown upward and backward.

[0035] Please refer to Figure 2 , Figure 5 , Figure 6 , Figure 8 and Figure 9 In a preferred embodiment, the drive mechanism includes two support frames 21, both of which are fixedly installed on one side of the collection box 4. A mounting box 8 is provided between the two support frames 21. A fixing plate 28 is provided inside the mounting box 8. A first motor 27 is provided on one outer wall of the fixing plate 28. The output shaft of the first motor 27 passes through the fixing plate 28, and a cam 26 is fixedly connected to the output shaft of the first motor 27. A connecting rod 23 is provided at one end of the knife bar 9. One end of the connecting rod 23 passes through the mounting box 8, and a moving plate 25 is provided at one end of the connecting rod 23. One side of the moving plate 25 abuts against the cam 26. A return spring 24 is provided between the moving plate 25 and one inner wall of the mounting box 8. The return spring 24 is wound around the outer wall of the connecting rod 23.

[0036] In the specific implementation process, the top inner wall and bottom inner wall of the mounting box 8 are provided with limiting frames 29, and the top outer wall and bottom outer wall of the moving plate 25 are provided with sliders 30. The sliders 30 are slidably connected in the limiting frames 29. During the reciprocating motion of the moving plate 25, the sliders 30 installed on the top and bottom outer walls of the moving plate 25 slide in the limiting frames 29 set on the top and bottom inner walls of the mounting box 8, thereby restricting the movement direction of the moving plate 25, ensuring that it always moves in a straight line, and preventing deviation.

[0037] Specifically, the first motor 27 starts, and its output shaft drives the fixedly connected cam 26 to rotate at a constant speed. During the rotation, the contour surface of the cam 26 remains in contact with one side of the moving plate 25. When the protruding part of the cam 26 rotates to the contact position, the cam 26 pushes the moving plate 25 to move away from the axis of the cam 26. Since the moving direction of the moving plate 25 is consistent with the length direction of the cutter bar 9, the moving plate 25 drives the connecting rod 23 to move in the same direction, thereby driving the cutter bar 9 and the moving cutter group 19 to move synchronously. Through the cooperation of the cam 26 and the return spring 24, the continuous rotational motion of the first motor 27 is converted into the high-speed reciprocating linear motion required by the moving cutter group 19, thereby driving the moving cutter group 19 to cut continuously, smoothly and efficiently.

[0038] Working principle: Before operation, the operator activates the adjustment component 3 via the control console 2. The movable end of the electric telescopic rod is fixedly connected to the fixed blocks 17 on both sides of the collection box 4. Through the telescopic movement, the collection box 4 and the cutting mechanism fixedly connected to it are raised and lowered as a whole, so that the ground clearance of the cutting mechanism matches the current growth height of the mugwort, realizing the rapid adjustment of the harvesting platform height. When the harvester body 1 moves forward, the vines and mugwort plants mixed in with the mugwort first come into contact with the dividing plate 5. Since the dividing plate 5 is arrow-shaped with the tip pointing forward, the upright mugwort with thicker stems is lifted. The grass slides past both sides of the dividing plate 5 and continues to move backward into the shearing zone. Meanwhile, the creeping, soft, and easily entangled vines are lifted by the tip of the dividing plate 5 and guided upward along the inclined surface of the dividing plate 5. During this lifting process, auxiliary blades 12 on the outer walls of both sides of the dividing plate 5 pre-cut the vines, breaking them into small segments. These shredded segments are scattered to the sides or upward by the airflow and vibration of the machine, preventing them from directly entering the shearing zone below. After being separated by the dividing plate 5, the artemisia plants continue to move backward, first contacting the installation... The guide block 20 at the front end of the fixed blade guides and straightens the upright mugwort stem, ensuring it accurately enters the shearing area between the moving blade and the fixed blade. Once inside the shearing area, the mugwort stem is clamped between the lower edge of the fixed blade and the upper edge of the moving blade. Then, the drive mechanism drives the blade holder 9 to perform high-speed reciprocating linear motion within the fixed frame 10. Since multiple moving blades are riveted to the blade holder 9, all moving blades move synchronously. When the moving blades slide inside the blade guard 7, the cutting edges of the moving blades and the fixed blades form a shearing action. The cutting mechanism, similar to the working principle of scissors, cleanly cuts the mugwort stems above the root. After being cut, the mugwort loses its support from below and, under the combined action of gravity and the forward thrust of the machine, tilts backward. The tilted mugwort falls directly onto the conveyor belt 6 installed inside the collection box 4, and finally falls to the bottom of the collection box 4 under the action of gravity, achieving orderly accumulation. After the moving blade assembly 19 completes one cutting stroke, it returns to the starting position under the drive mechanism, ready for the next cutting. As the machine moves forward continuously, the above process is repeated continuously, realizing the continuous harvesting of mugwort.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
