Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a variable-angle, variable-speed, orderly separation device and method for crop planting. Background Technology

[0002] As moxibustion and health preservation gain increasing attention, mugwort is being cultivated on a large scale in my country. However, many regions still rely on manual cultivation, which is not only labor-intensive but also inefficient. While conventional seeders can efficiently seed crops with relatively regular shapes, they are ill-suited for the long, slender roots of mugwort, which are prone to tangling. For example, the Chinese patent "A Semi-Automatic Mugwort Transplanter" (application number 202221044936.0), filed on April 9, 2022, is suitable for large-scale cultivation, saving significant labor costs and increasing efficiency, but still requires manual supervision to prevent material blockage.

[0003] The main technical problems existing in the field of artemisia seeding include:

[0004] 1. Artemisia roots are highly entangled: Artemisia roots are long and fibrous, and multiple roots easily entangle with each other. Traditional seed metering devices are mostly designed for regularly shaped seeds, which is not suitable for this special crop shape. As a result, Artemisia roots are prone to entanglement and blockage during the sowing process, affecting the efficiency and accuracy of seed metering.

[0005] 2. Insufficient equipment adaptability: Conventional seeding equipment on the market is mainly designed for grain crops or other cash crops and lacks the ability to handle long, narrow plants such as Artemisia argyi. This results in existing seeding equipment being unable to effectively handle the special shape requirements of Artemisia argyi, leading to low seeding efficiency and unsatisfactory results.

[0006] 3. Blockage problem: Due to the tendency of Artemisia argyi to entangle, and the fact that the internal design of the equipment is not adapted to the handling of this material, material blockage problems often occur. Even the "semi-automatic Artemisia argyi transplanter" with application number 202221044936.0, although it improves sowing efficiency in some aspects, still requires manual intervention to prevent blockage, and cannot achieve fully automated operation, thus reducing the continuity of operations and work efficiency.

[0007] 4. High labor intensity: The traditional method of planting Artemisia argyi relies on manual operation. Existing sowing equipment cannot fully meet the needs of Artemisia argyi planting, and manual intervention is still required, which makes the labor intensity high and reduces the overall work efficiency.

[0008] 5. Uneven sowing: Due to the inability of existing equipment to effectively separate and arrange the Artemisia argyi roots, uneven sowing occurs during the sowing process, resulting in planting that is too dense or too sparse, which affects the growth quality and yield of the crop.

[0009] Therefore, the problems with existing technologies mainly lie in their inability to effectively handle the entanglement characteristics of Artemisia annua, poor equipment adaptability, easy clogging, high labor intensity, and uneven sowing. There is an urgent need for an automated device that is more suitable for Artemisia annua seeding to solve these problems. Summary of the Invention

[0010] In order to overcome the problems of blockage caused by the material characteristics of artemisia in existing semi-automatic artemisia seeders and the low efficiency and high cost of the current large-scale manual planting of artemisia, this invention relates to an artemisia orderly separation device and method with variable angle and variable belt speed.

[0012] The variable angle and variable speed Aigen orderly separation device includes the following main parts: material box, angle adjustment device and variable gap differential belt separation device;

[0013] The material box is mainly composed of parts such as housing a, housing b, housing c, and housing d. The housings are connected by fasteners. Housings c and d are each provided with several threaded holes and slots. The horizontal brush fixing brackets a and b are provided with threaded holes and are fixed to housings c and d by fasteners. The vertical brush fixing brackets a and b are also provided with slots and are secured to housings c and d by fasteners. Vertical brush holders a and b are fixed to horizontal brush holders a and b. Threaded holes are provided on brush holders a and b for fixing them to vertical brush holders a and b. Seed protectors b and d are fixed to machine housings c and d by fasteners. Threaded holes are provided on seed protectors b and d for fixing seed protectors a and c to seed protectors b and d.

[0014] The angle adjustment device mainly consists of tension wheel shaft a, tension wheel shaft b, tension wheel roller a, tension wheel roller b, belt a, and belt b. Several bearings a are provided on the tension wheel shaft a, and the bearings a are installed in the tension wheel roller a. The tension wheel roller a and the belt a are in contact. The tension wheel shaft a has threads at both ends. The tension wheel shaft is installed in the arc groove of the housing c and the housing d using fasteners. The tension wheel shaft b, bearing b, and belt b are installed in the same way. When the position of the tension wheel shaft a and the tension wheel shaft b along the arc groove of the housing c and the housing d is adjusted, the tilt angle of the two belts can be changed.

[0015] The variable clearance differential belt separator mainly consists of a driven shaft support seat a, a driven shaft support seat b, a shaft support seat, a guide shaft a, a guide shaft b, a slider a, a slider b, a support rod a, a support rod b, an adjustment frame, bolts, a bolt fixing frame, and a guide shaft c.

Slider a and slider b are respectively installed on guide shaft a and guide shaft b. Driven shaft support seats a and b are respectively installed and fixed on the two sliders. Driven shaft a and driven shaft b are also installed and fixed on driven shaft support seats a and driven shaft support seats b. The adjustment frame has two holes, one for the guide shaft c and the other for the bolt. Several nuts are installed on the bolt. Support rods a and b are respectively provided between the adjustment frame and sliders a and b. When adjusting the position of the support frame using the nuts on the bolt, the distance between sliders a and b along guide shafts a and b can be indirectly controlled using the support rods, thereby controlling the gap between the two belts.

[0016] Furthermore, the housings c and d of the variable angle and variable belt speed orderly separation device are respectively provided with a horizontal brush fixing frame a and a horizontal brush fixing frame b, which are connected by a fixing component. The horizontal brush fixing frame a and the horizontal brush fixing frame b are respectively provided with a vertical brush fixing frame a and a vertical brush fixing frame b, which are used to control the vertical movement of the brush fixing frame a and the brush fixing frame b. Both the brush fixing frame a and the brush fixing frame b are provided with bristles to block the seeds and prevent leakage.

[0017] Furthermore, the housings c and d of the variable angle and variable belt speed Eigen orderly separation device are provided with several mounting holes such as bearing end caps and shaft support seats, and the housings c and d are respectively provided with tensioning wheel, driven shaft a and driven shaft b sliding groove holes.

[0018] Furthermore, the housings a and b of the variable angle and variable belt speed Eigen orderly separation device are connected by fasteners, housing b and c are connected by fasteners, housing c and d are connected by fasteners, and housing d and a are connected by fasteners.

[0019] Furthermore, the variable angle and variable belt speed Eigen orderly separation device is provided with several bearing end caps, and bearings are installed inside. The bearings with bearing end caps are installed on the drive shaft a and drive shaft b.

[0020] Furthermore, the active shaft a and the second driven shaft of the variable angle and variable speed Eigen orderly separation device are respectively provided with belt a and belt b, which have patterns to increase the friction between the material and the contact surface.

[0021] Furthermore, the variable angle and variable belt speed Eigen orderly separation device is provided with several bolt fixing brackets and several shaft support seats. Adjustment brackets are provided on the gap adjustment shaft and bolts, which are used to adjust the position of the top rod. The adjustment brackets and sliders a and b are supported by support rods a and b, forming an umbrella-shaped mechanism, which is used to push sliders a and b to change the position of driven shaft support seat a and driven shaft support seat b, thereby changing the gap between driven shaft a and driven shaft b, and thus changing the gap between belt a and belt b.

[0022] Furthermore, in the variable angle and variable belt speed Eigen orderly separation device, the driven shaft a and the driven shaft b are respectively provided with bearing a and bearing b, the driven shaft roller a and the driven shaft roller b are respectively provided on the bearing a and the bearing b, and the driven shaft roller a and the driven shaft roller b are respectively provided with belt a and belt b.

[0023] Furthermore, the variable angle and variable belt speed orderly separation device has a housing c and a housing d, and a seed protection plate b and a seed protection plate d are provided on the housing c and housing d, and a seed protection plate d and a seed protection plate c are provided between the seed protection plate b and the seed protection plate d.

[0024] This invention also provides a method for sowing Artemisia argyi using a variable-angle, variable-speed, ordered separation device, comprising the following steps:

[0025] Place the artemisia seed into the seed box of the seeder;

[0026] Start the tractor, and the tractor transmits power to the drive shaft a and drive shaft b through the power system, thereby driving the variable angle and variable belt speed artemisinin orderly separation device to achieve discrete and orderly separation of artemisinin.

[0027] Furthermore, the gap between belts a49 and b50 is adjusted by moving sliders a20 and b21 along the slot direction, and the tension of the belt is adjusted by tension rollers a38 and c46, thereby adjusting the discharge volume of the artemisia annua orderly separation device for the variable angle and variable belt speed. This helps to handle artemisia annua of different shapes and sizes to ensure the separation effect.

[0028] Furthermore, by moving sliders a20 and b21 along the groove direction, the belt tension wheel shafts a9 and b10 can be adjusted to move along the groove direction, which facilitates the adjustment of the belt's tilt angle and enhances the device's adaptability to planting Artemisia argyi of different shapes and sizes.

[0029] The beneficial effects of this invention are:

[0030] First, the umbrella-shaped mechanism composed of slider a, slider b, and push rod described in this invention reduces friction and facilitates subsequent automatic control of the gap, thereby achieving control over the discharge rate of Artemisia argyi. The angle adjustment device described in this invention allows for more flexible control of the inclination angle of the two belts, adapting to Artemisia argyi with different material characteristics, such as the number of rootlets, different lengths, and different thicknesses. The variable-angle, variable-speed Artemisia argyi orderly separation device described in this invention, for Artemisia argyi with complex material characteristics, utilizes the differential speed movement of the two belts to achieve separation of the Artemisia argyi, preventing blockage and eliminating the need for manual supervision. The variable-angle, variable-speed Artemisia argyi orderly separation device described in this invention includes horizontal brush fixing frames a and b on the seed box, indirectly fixing the brush fixing frames a and b, thereby effectively cleaning the seeds at the end of the belt and preventing leakage from the seed box.

[0031] Secondly, the technical solution of this invention solves the following technical problems in existing Artemisia argyi sowing technology in industrial applications:

[0032] 1. Artemisia Root Entanglement Problem: In traditional artemisia root sowing processes, the roots are prone to entanglement, affecting sowing efficiency and uniformity. The artemisia root discrete-order separation device of this invention effectively solves the artemisia root entanglement problem, achieving orderly separation of the roots and greatly improving sowing efficiency and precision.

[0033] 2. Insufficient Automation in Sowing: In existing technologies, the sowing of Artemisia argyi still requires a significant amount of manual labor, resulting in low efficiency and high costs. This invention, by employing an automated control device, achieves a fully automated Artemisia argyi sowing process, reducing manual intervention and improving work efficiency and sowing accuracy.

[0034] 3. Poor adaptability to different terrains and seasons: Traditional seed metering devices often lack adaptability when facing the sowing needs of Artemisia argyi in different terrains and seasons. Through the design of this invention, the equipment possesses excellent adaptability and can be adjusted according to different seasons and regions to meet the sowing needs under various terrain and climatic conditions.

[0035] 4. Seeding survival rate: Currently, there is almost no research or equipment on seed metering devices for strip seed sowing, and some seed metering devices are prone to damaging the seeds, affecting crop growth. This invention causes almost no damage to the Artemisia argyi roots during the sowing process, thus improving the germination rate and survival rate of the crop.

[0036] Significant technological advancements:

[0037] 1. Significantly improved sowing efficiency: This invention uses automated devices for sowing operations, which increases work efficiency several times compared to traditional manual and semi-automatic equipment, reduces labor costs, and can meet the needs of large-scale planting.

[0038] 2. Improved precision and uniformity: The unique orderly separation device for Artemisia argyi roots ensures uniform distribution of Artemisia argyi roots, avoiding missed sowing and double sowing problems, and greatly improving sowing precision and effect.

[0039] 3. Easy to operate and low maintenance cost: The equipment has a simple and reasonable structure, is easy to operate, has low maintenance cost, is suitable for large-scale planting application scenarios, and is highly adaptable, able to cope with different terrain and seasonal conditions.

[0040] 4. Strong environmental adaptability: Through the optimization of the device structure, the equipment can adapt to different soil conditions and seasonal changes, providing more flexible sowing solutions and further improving the operability and yield of agricultural production.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0047] like Figure 2 As shown, a horizontal brush fixing bracket a34 and a horizontal brush fixing bracket b29 are provided between the machine housing a1 and the machine housing b2, and are connected by screws. The horizontal brush fixing bracket a34 and the horizontal brush fixing bracket b29 are respectively connected to the vertical brush fixing bracket a34 and the vertical brush fixing bracket b30 by bolts, which are used to control the vertical movement of the brush fixing bracket a34 and the brush fixing bracket b30. The brush fixing bracket a36 and the brush fixing bracket b31 are both provided with bristles to block seeds and prevent material leakage.

[0048] like Figure 1As shown, housings a1, b2, c3, and d4 are each provided with several threaded holes. Screws are used to fix bearing end caps a5 and a6, bolt fixing brackets 26, and shaft support seats 17 to their surfaces.

[0049] like Figure 2 As shown, a drive shaft a4 and a drive shaft b5 are provided between housing c3 and housing d4, and belts a49 and b50 are respectively provided on the two shafts.

[0050] like Figure 1 As shown, sliders a20 and b21 are provided on the housing c3. Driven shaft support seats a11 and b12 are provided on the two sliders respectively. Driven shafts a13 and b14 are provided on the two support seats. When the nuts on the bolts 25 on the bolt fixing bracket 26 are tightened or loosened, the movement of the adjusting bracket 24 can be changed. Thus, the movement of slider a20 along the groove direction is controlled by the support rod a22. The movement of the second slider 21 is similar. The gap of the seed metering device is controlled by the position of the two driven shafts.

[0051] like Figure 1 As shown, after the positions of driven shaft a13 and driven shaft b14 are determined, the tilt angle of the two belts is changed by adjusting the positions of tension wheel shaft a9 and tension wheel shaft b10. Finally, the belts a49 and b50 are tensioned by adjusting the positions of tension wheel shaft c15 and tension wheel shaft d16.

[0052] like Figure 1 As shown, several tensioner shafts have threads at both ends and can be fixed to the housing with nuts.

[0053] like Figure 2 As shown, when the drive shaft a7 rotates counterclockwise, the belt a49 will move downwards at a relatively slow speed. When the drive shaft b8 rotates counterclockwise, the belt b50 will move upwards at a relatively fast speed. At this time, the seed will tumble inside the seed metering device, and after coming out of the gap, it will fall out of the seed metering device after passing through several seed protection plates below. The rotation direction and rotation speed of the drive shafts a7 and b8 are not entirely based on the description in this article and need to be adjusted appropriately according to the actual working conditions.

[0054] The differential belt-type artemisia seed separator provided by this invention achieves orderly separation of artemisia seeds by controlling the drive shaft and driven shaft, belt system, brush assembly, and support adjustment device. Specifically, the seed box, as the uppermost part of the device, is used to hold the artemisia seeds. Below the seed box, housings a1, b2, c3, and d4 are arranged in sequence. These housings are connected to each other by bolts to form a stable frame structure. Bearing end caps a5 and b6, bolt fixing brackets 26, and shaft support seats 17 are fixed to the housings by bolts, making the device structure stable.

[0055] like Figure 2As shown, horizontal brush holders a34 and b29 are installed between housing a1 and housing b2. These two holders are connected to the housings by screws, and horizontal brush holders a34 and b29 are connected to vertical brush holders a35 and b30 by bolts, making brush holders a36 and b31 adjustable in the vertical direction. Brush holders a36 and b31 are equipped with bristles to block excess material, prevent leakage, and organize the material, ensuring that the amount of material entering the belt system is appropriate and the arrangement is orderly.

[0056] Drive shafts A7 and B8 are installed between housings C3 and D4. Drive shaft A7 is connected to belt A49, and its counter-clockwise rotation drives belt A49 to slowly convey material downwards. Drive shaft B8 is connected to belt B50, and its faster counter-clockwise rotation drives belt B50 to convey material upwards. Due to the different conveying directions and speeds of belts A49 and B50, the material is tumbled and gradually conveyed under the clamping action of the two belts, eventually falling out orderly from the gap. By controlling the rotation direction and speed of drive shafts A7 and B8, the separation effect of the material can be adjusted according to the actual working conditions.

[0057] Slider A20 and slider B21 are installed on the housing C3. Each slider has a driven shaft support seat A11 and a driven shaft support seat B12, respectively, which fix the positions of driven shafts A13 and B14. When the nuts on bolts 25 of the bolt fixing bracket 26 are tightened or loosened, the movement of the adjusting bracket 24 causes support rods A22 and B23 to push sliders A20 and B21 along the guide groove, thereby changing the position of the driven shafts and controlling the gap between belts A49 and B50 to meet the separation requirements of different specifications of Eigers.

[0058] After determining the position of the driven shaft, the tilt angles of belts a49 and b50 can be changed by adjusting the positions of tension wheel shafts a9 and b10, further optimizing the transmission effect. Finally, by adjusting the positions of tension wheel shafts c15 and d16, belts a49 and b50 are tensioned to ensure that the belts do not become slack during operation, thereby improving the stability and efficiency of separation.

[0059] The entire conveying and separation process achieves efficient and orderly separation of the seeds by controlling the belt speed, adjusting the belt gap, and setting up the brush assembly. During the tumbling conveying process, the seeds are supported and organized by multiple seed protection plates 51 and c52, thus achieving orderly seed release.

[0060] This invention provides a fully automatic Artemisia argyi seeder, the core component of which is an orderly Artemisia argyi separation device. This device achieves orderly separation and uniform sowing of Artemisia argyi through different transmission mechanisms and adjustment devices. The working principle is as follows:

[0061] Artemisia argyi discrete separation process: Artemisia argyi enters the seeder through the seed box. The orderly separation device for Artemisia argyi consists of multiple belts and multiple drive and driven shafts. First, the Artemisia argyi passes through the horizontal brush fixing frames a34 and b29 in the discrete separation device. These fixing frames are connected to the machine housing a1 and b2 by screws, and to the vertical brush fixing frames a34 and b30 by bolts. These brushes control the flow of Artemisia argyi, preventing tangling and ensuring uniform separation.

[0062] Adjustment of the belt drive system: During the operation of the separation device, drive shafts a7 and b8 are located between housing c3 and housing d4, transmitting power through belts a49 and b50. To ensure stable operation of the belt system, bearing end caps a5 and b6 are fixed to the housing with screws, guaranteeing system stability.

[0063] Control of the slider and driven shaft: The housing c3 is equipped with sliders a20 and b21, which are respectively fixed with driven shaft support seats a11 and b12. The positions of driven shafts a13 and b14 can be adjusted by tightening or loosening the nuts on the bolt fixing bracket 26, thereby controlling the movement of the sliders and thus controlling the seed spacing. This sliding control structure allows the equipment to flexibly adjust the seed spacing to adapt to different sowing needs.

[0064] The function of the tension pulleys: The tension and tilt angle of the belt in the system are adjusted through tension pulley shafts a9, b10, c15, and d16. By adjusting the positions of these tension pulleys, the tilt angles of belts a49 and b50 can be changed, ensuring proper tension in the belt drive system and guaranteeing orderly sowing of Artemisia argyi.

[0065] The belt's movement pattern during operation is as follows: when the drive shaft a7 rotates counterclockwise, belt a49 moves downwards at a slower speed, while when the drive shaft b8 rotates counterclockwise, belt b50 moves upwards at a faster speed. This belt movement pattern with different speeds causes the seeds to tumble inside the seed metering device and gradually fall to the ground through the gaps in the device, thus achieving a uniform sowing effect.

[0066] The equipment has a reasonable structural design and can adapt to the sowing needs under various terrain and climate conditions. In particular, through the automated control system and flexible adjustment mechanism, it ensures uniform separation and efficient sowing of the seedlings.
