Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a variable-angle, variable-belt-speed, orderly separation device and method for argyi root used in the field of crop planting. Background Art

[0002] As moxibustion health care is increasingly valued, mugwort is planted on a large scale in my country. However, many areas still rely on manual planting, which is not only labor-intensive but also inefficient. Conventional seeders can plant seeds for crops of regular shapes with high efficiency, but because mugwort roots are long and easy to get entangled with each other, conventional seeders are difficult to adapt to the planting of mugwort roots. For example, the Chinese patent "A semi-automatic mugwort transplanter" applied for on April 9, 2022, application number: 202221044936.0, although it is suitable for large-scale planting, can save a lot of labor and has high work efficiency, but it still requires manual care to prevent material blockage.

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

[0004] 1. Mugwort roots are prone to entanglement: Mugwort roots are long and fibrous, and multiple roots are easily entangled with each other. Traditional seeders are mostly designed for regular-shaped seeds, which are not suitable for this special type of crop. As a result, the roots are easily entangled and blocked during the sowing process, affecting the efficiency and accuracy of seeding.

[0005] 2. Insufficient equipment adaptability: Conventional seeding equipment on the market is mainly designed for food crops or other cash crops, and is not capable of handling long strips of plants such as mugwort. This results in the inability of existing seeding equipment to effectively handle the special shape requirements of mugwort, resulting in low seeding efficiency and unsatisfactory results.

[0006] 3. Blockage problem: Since mugwort is easy to tangle, and the internal design of the equipment is not suitable for handling this material, material blockage problems often occur. Even the "semi-automatic mugwort transplanter" with application number 202221044936.0, although it improves the sowing efficiency in some aspects, it still requires manual intervention to prevent blockage, and cannot achieve fully automated operation, which reduces the continuity and work efficiency of the operation.

[0007] 4. High labor intensity: The traditional method of Artemisia selengensis cultivation relies on manual operation. The existing sowing equipment cannot fully adapt to the needs of Artemisia selengensis cultivation and still requires manual care and intervention, which makes the labor intensity high and reduces the overall work efficiency.

[0008] 5. Uneven sowing: As the existing equipment cannot effectively separate and arrange the mugwort roots, uneven sowing occurs during the sowing process, resulting in over-dense or over-sparse planting, which affects the growth quality and yield of crops.

[0009] Therefore, the problems existing in the existing technology mainly focus on the inability to effectively deal with the winding characteristics of Aigen, poor equipment adaptability, easy clogging, high labor intensity, and uneven sowing. There is an urgent need for an automated equipment that is more suitable for Aigen seeding to solve these problems. Summary of the invention

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

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

[0027] Further, the gap between belt a49 and belt b50 is adjusted by moving slider a20 and slider b21 along the slot direction, and the tension of the belt is adjusted by tensioning roller a38 and tensioning roller c46, so as to adjust the displacement of Aigen by the variable angle and variable belt speed Aigen orderly separation device, which helps to deal with Aigen of different shapes and sizes to ensure the separation effect.

[0030] First, the umbrella-shaped mechanism composed of the slider a, slider b, and top rod described in the present invention reduces friction and facilitates the subsequent automatic control of the gap, thereby realizing the control of the displacement of the mugwort root. The angle adjustment device described in the present invention can more flexibly control the inclination angles of the two belts to adapt to mugwort roots with different material characteristics, such as the number of mugwort roots, the different lengths of mugwort roots, and the different thicknesses of mugwort roots. The variable-angle and variable-belt-speed mugwort orderly separation device described in the present invention, for mugwort roots with complex material characteristics, uses the differential motion of two belts to achieve the separation of mugwort roots, and the mugwort roots will not be blocked and do not require human care. The variable-angle and variable-belt-speed mugwort orderly separation device described in the present invention is provided with a brush horizontal fixing frame a and a brush horizontal fixing frame b on the seed box, which indirectly fix the brush fixing frame a and the brush fixing frame b, thereby effectively cleaning the seeds at the end of the belt and preventing leakage from the seed box.

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

[0032] 1. The problem of entanglement of mugwort root: In the traditional mugwort root sowing process, mugwort root is easy to entangle, which affects the efficiency and uniformity of sowing. The mugwort root discrete-order separation device of the present invention effectively solves the problem of entanglement of mugwort root, realizes the orderly separation of mugwort root, and greatly improves the efficiency and accuracy of sowing.

[0033] 2. Insufficient automated sowing: In the prior art, the sowing of Artemisia argyi still requires a lot of manual operation, which is inefficient and costly. The present invention realizes a fully automated sowing process of Artemisia argyi by adopting an automated control device, reduces manual intervention, and improves work efficiency and sowing accuracy.

[0034] 3. Poor adaptability to different terrains and seasons: Traditional seeders are often not adaptable enough to the sowing needs of Artemisia selengensis in different terrains and seasons. Through the design of the present invention, the device has good adaptability and can be adjusted according to different seasons and regions to meet the sowing needs under various terrains and climatic conditions.

[0035] 4. Seeding survival rate: Currently, there is almost no research on seeding devices and machines for strip seed sowing, and some seeding devices are prone to damage seeds, affecting crop growth. During the sowing process of Artemisia argyi, the present invention causes almost no damage to Artemisia argyi, thereby improving the germination rate and survival rate of crops.

[0036] Significant technological advancements:

[0037] 1. Significantly improved sowing efficiency: The present invention adopts an automated device for sowing operations. Compared with traditional manual and semi-automatic equipment, the work efficiency is increased several times, the labor cost is reduced, and it can meet the needs of large-scale planting.

[0038] 2. Improved accuracy and uniformity: The unique orderly separation device of Artemisia argyi ensures the uniform distribution of Artemisia argyi, avoiding the problems of missed sowing and re-seeding, and greatly improving the sowing accuracy and effect.

[0039] 3. Easy operation and low maintenance cost: The equipment has a simple and reasonable structure, is easy to operate, and has low maintenance cost. It is suitable for large-scale planting applications and has strong adaptability 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, provide more flexible sowing solutions, and further improve the operability and yield of agricultural production.

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

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

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

[0048] like Figure 1As shown, casing a1, casing b2, casing c3, ​​casing d4 are all provided with a plurality of threaded holes, and bearing end cover a5, bearing end cover a6, bolt fixing frame 26, shaft support seat 17 are fixed on their surfaces by screws.

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

[0050] like Figure 1 As shown, a slider a20 and a slider b21 are provided on the casing c3, ​​and a driven shaft support seat a11 and a driven shaft support seat b12 are provided on the two sliders respectively, and a driven shaft a13 and a driven shaft b14 are provided on the two support seats. When the nut on the bolt 25 on the bolt fixing frame 26 is tightened or loosened, the movement of the adjustment frame 24 can be changed, so that the movement of the slider a20 along the groove direction can be controlled by the support rod a22. The movement of the second slider 21 is similar, and 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 inclination angles of the two belts are changed by adjusting the positions of tensioning wheel shaft a9 and tensioning wheel shaft b10, and finally belt a49 and belt b50 are tensioned by adjusting the positions of tensioning wheel shaft c15 and tensioning wheel shaft d16.

[0052] like Figure 1 As shown, both ends of several tight pulley shafts are threaded and can be fixed to the housing with nuts.

[0053] like Figure 2 As shown, when the driving shaft a7 rotates counterclockwise, the belt a49 will move downward at a slower speed. When the driving shaft b8 rotates counterclockwise, the belt b50 will move upward at a faster speed. At this time, the Aigen will roll inside the seed meter, come out from the gap, pass through several seed protection plates below, and fall out of the seed meter. The rotation direction and rotation speed of the driving shaft a7 and the driving shaft b8 are not entirely based on what is described in this article, and need to be adjusted appropriately according to actual working conditions.

[0054] The differential belt type Aigen orderly separator provided by the present invention realizes orderly separation of Aigen by controlling the driving shaft and the driven shaft, the belt system, the brush assembly and the supporting and adjusting device. Specifically, the seed box is used to hold Aigen as the uppermost part of the device. The casing a1, the casing b2, the casing c3 and the casing d4 are arranged in sequence below the seed box. These casings are connected to each other by bolts to form a stable frame structure. The bearing end cover a5, the bearing end cover b6, the bolt fixing frame 26 and the shaft support seat 17 are fixed on the casing by bolts to make the device structure stable.

[0055] like Figure 2As shown, a brush horizontal fixing frame a34 and a brush horizontal fixing frame b29 are installed between the housing a1 and the housing b2, and the two fixing frames are connected to the housing by screws, and the brush horizontal fixing frame a34 and the brush horizontal fixing frame b29 are connected to the brush vertical fixing frame a35 and the brush vertical fixing frame b30 by bolts, so that the brush fixing frame a36 and the brush fixing frame b31 are adjustable in the vertical direction. Brush fixing frames a36 and the brush fixing frame b31 are provided with bristles to block excess Aigen, prevent leakage, and organize Aigen, so as to ensure that the number of Aigen entering the belt system is appropriate and arranged in an orderly manner.

[0056] A driving shaft a7 and a driving shaft b8 are installed between the housing c3 and the housing d4. The driving shaft a7 is connected to the belt a49, and drives the belt a49 to slowly move downward by rotating counterclockwise; the driving shaft b8 is connected to the belt b50, and drives the belt b50 to move upward by rotating counterclockwise at a relatively fast speed. Due to the different transmission directions and speeds of the belts a49 and b50, the Aigen rolls under the clamping action of the two belts and is gradually transported, and finally falls out of the gap in an orderly manner. By controlling the rotation direction and speed of the driving shafts a7 and b8, the separation effect of the Aigen can be adjusted according to the actual working conditions.

[0057] Slide block a20 and slide block b21 are installed on the housing c3, ​​and the two slide blocks are provided with driven shaft support seat a11 and driven shaft support seat b12 respectively, and the positions of driven shaft a13 and driven shaft b14 are fixed by the support seat. When the nut of bolt 25 on bolt fixing frame 26 is tightened or loosened, the movement of adjustment frame 24 causes support rod a22 and support rod b23 to push slide block a20 and slide block b21 to move along the guide groove, thereby changing the position of the driven shaft, and then controlling the gap between belt a49 and belt b50, so as to meet the separation requirements of different specifications of Aigen.

[0058] After the position of the driven shaft is determined, the inclination angle of the belt a49 and the belt b50 can be changed by adjusting the position of the tensioning wheel shaft a9 and the tensioning wheel shaft b10 to further optimize the transmission effect. Finally, by adjusting the position of the tensioning wheel shaft c15 and the tensioning wheel shaft d16, the belt a49 and the belt b50 are tensioned to ensure that the belt will not be loose during operation, thereby improving the stability and efficiency of separation.

[0059] The entire conveying and separation process achieves efficient and orderly separation of the Aigen by controlling the belt speed, adjusting the belt gap and setting the brush assembly. During the tumbling conveying process, the Aigen is supported and arranged by multiple seed protection plates 51 and seed protection plates c52, so that the seeds fall out in an orderly manner.

[0060] The present invention provides a fully automatic mugwort seeding machine, the core device of which is a mugwort orderly separation device, which realizes orderly separation and uniform seeding of mugwort through different transmission mechanisms and adjustment devices. The working principle is as follows:

[0061] Aigen discrete separation process: Aigen enters the seeder through the seed box. Aigen's orderly separation device consists of multiple belts and multiple driving and driven shafts. First, Aigen passes through the brush horizontal fixing frame a34 and brush horizontal fixing frame b29 in the discrete separation device. These fixing frames are connected to the housing a1 and housing b2 by screws, and connected to the brush vertical fixing frame a34 and brush vertical fixing frame b30 by bolts. These brushes can control the flow of Aigen, so that Aigen does not get entangled and is evenly separated.

[0062] Adjustment of belt drive system: During the working process of the separation device, driving shafts a7 and b8 are arranged between the casing c3 and the casing d4, and power is transmitted through belts a49 and b50. In order to achieve stable operation of the belt system, the bearing end cover a5, the bearing end cover b6 and other structures are fixed to the casing by screws to ensure the stability of the system.

[0063] Control of the slider and the driven shaft: The housing c3 is provided with a slider a20 and a slider b21, which are respectively fixed with a driven shaft support seat a11 and a driven shaft support seat b12. The positions of the driven shafts a13 and b14 can be adjusted by tightening or loosening the nuts on the bolt fixing frame 26, thereby controlling the movement of the slider and further controlling the gap of the Aigen seeding. This sliding control structure enables the device to flexibly adjust the seeding gap to adapt to different sowing requirements.

[0064] Adjustment of the tensioning wheel: The tension and inclination angle of the belt in the system are adjusted through the tensioning wheel shaft A9, the tensioning wheel shaft B10, the tensioning wheel shaft C15 and the tensioning wheel shaft D16. By adjusting the position of these tensioning wheels, the inclination angles of the belt A49 and the belt B50 can be changed to ensure that the tension of the belt transmission system is appropriate and the orderly sowing of the Aigen is guaranteed.

[0065] The movement pattern of the belt during operation: when the driving shaft a7 rotates counterclockwise, the belt a49 moves downward at a slower speed, and when the driving shaft b8 rotates counterclockwise, the belt b50 moves upward at a faster speed. This belt movement mode with different speeds makes the Aigen roll inside the seed metering device and gradually fall to the ground through the gap of the seed metering 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 climatic conditions. In particular, it ensures the uniform separation and efficient sowing of the aigen through the automatic control system and flexible adjustment mechanism.
