Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to a differential belt type Aigen ordered separator and a method for use 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 very labor-intensive and has low work efficiency. Conventional seeders can plant seeds for crops of regular shapes with high efficiency, but because mugwort roots are long and easy to entangle with each other, conventional seeders are difficult to adapt to the planting of mugwort roots. For example, the Chinese patent "A semi-automatic mugwort root transplanter" (application number: 202221044936.0) applied for on April 9, 2022, 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 of the prior art Aigen seeding equipment include the following aspects:

[0004] 1. The problem of entanglement of mugwort roots: Since mugwort roots are long and easily entangled, conventional seeders can efficiently seed regular crops, but are difficult to adapt to the seeding of mugwort roots. This entanglement phenomenon will cause the seeder to become blocked, affecting the sowing efficiency.

[0005] 2. Low automation: Although existing equipment (such as the semi-automatic Aigen transplanter with application number 202221044936.0) can plant large areas and save manual labor, it still requires manual care to prevent material blockage. This greatly limits the sowing efficiency and automation level, and increases labor costs and labor intensity.

[0006] 3. Insufficient seeding accuracy: When the existing equipment is used to seed the mugwort, the length of the mugwort is irregular and it is easy to get tangled, resulting in uneven seeding, which affects the growth effect and yield of the crop and cannot meet the requirements of high-standard seeding operations.

[0007] 4. Risk of blockage: During the transmission process, due to its shape and entanglement, Aigen can easily cause blockage inside the seed meter, thereby interrupting the sowing process and requiring frequent shutdowns for maintenance, further reducing sowing efficiency.

[0008] In summary, the existing technology has problems such as entanglement, low degree of automation, insufficient seeding accuracy and blockage risk in the process of seeding of Artemisia argyi. There is an urgent need for a seeding device that is efficient, automated and adapted to the characteristics of Artemisia argyi to solve these technical bottlenecks. Summary of the invention

[0009] In order to overcome the problems of clogging of existing Aigan seed metering devices due to the material characteristics of Aigan and the low efficiency and high cost of artificial planting of Aigan, the present invention relates to a fully automatic differential belt Aigan orderly separator, which has the following features:

[0010] The differential belt type Aigen ordered separator is composed of a seed box, a separator device, and a gap adjustment device. The seed box serves as a container for filling Aigen; the separator device mainly includes a casing a, a casing b, a casing c, a casing d, a driving shaft a, a driving shaft b, a bearing end cover a, a bearing end cover b, a tensioning bolt a, a tensioning bolt b, a driven shaft a, a bearing a, a roller a, a driven shaft b, a bearing b, a roller b, a tensioning shaft a, a tensioning bearing a, a tensioning roller a, a tensioning shaft b, a tensioning bearing b, a tensioning roller c, a belt a, a belt b, a brush plate a, a brush plate b, a baffle a, and a baffle b; the gap adjustment device mainly includes a support seat a, a support seat b, a support seat c, a support seat d, a support seat e, a support seat f, a guide shaft a, a guide shaft b, a support seat g, a support seat h, a slider a, a slider b, a support seat i, a support seat j, a support seat k, a support seat l, an adjustment bolt, a guide shaft c, and an adjustment frame.

[0011] The differential belt type Aigen orderly separator is characterized in that a belt a and a belt b are arranged between the housing a and the housing b, the power source of the belt a is the driving shaft a, the middle of the belt a is the tensioning roller a, the belt a is tensioned by the tensioning roller a on the tensioning shaft, the other side of the belt a is the roller a, the roller a is mounted on the bearing a, the bearing a is fixed on the driven shaft a, the belt b is similar, and the displacement of the separator is controlled by adjusting the driven shaft a and the driven shaft b;

[0012] The gap adjustment device is characterized in that a guide shaft a is provided between the support seat c and the support seat i, and a slider a is provided on the guide shaft a. The slider a can slide on the guide shaft a, and the support seat c is connected and fixed on the slider a. The support seat c fixes the driven shaft a, and the driven shaft a is also installed in the slot hole on the adjustment frame. The driven shaft b is installed in the same way as the driven shaft a. There are two holes on the adjustment frame (42), one hole is installed on the adjustment bolt, and the adjustment frame can be fixed at a corresponding position by adjusting the position of the nut, and the other hole is installed on the guide shaft c to guide the adjustment frame. The size of the gap can be adjusted by the device. For two belts at different inclination angles, the device can adjust the horizontal gap while ensuring that the heights of the two driven shafts in the vertical direction are consistent;

[0013] The belt a and the belt b are textured belts, so as to increase the friction between the belts and the agar.

[0014] A bearing is arranged inside the tensioning roller, and the bearing is mounted on the tensioning shaft. Holes are arranged at both ends of the tensioning wheel shaft, and the tensioning bolts pass through the holes and are fixed to the support seat. The position of the tensioning shaft is adjusted by using the nut on the tensioning bolt, thereby adjusting the tension of the belt.

[0015] The housing a and housing b of the separator device are provided with a plurality of mounting holes such as a bearing end cover and a shaft support seat, and the housing a and housing b are respectively provided with sliding slot holes of a tensioning wheel, a driven shaft a and a driven shaft b.

[0016] The brush a and brush b of the separator device are installed and fixed on the casing a and casing b. The brush a and brush b can block the material in the seed box to prevent leakage. The ends of the brush a and brush b are soft iron sheets that can be attached to the belt surface to prevent leakage of the Aigen.

[0017] The present invention also provides a method for separating Artemisia argyi using a differential belt Artemisia argyi orderly separator, comprising the following steps:

[0018] (1) Filling the Artemisia argyi root into the seed box (1);

[0019] (2) The driving shaft a (6) and the driving shaft b (7) rotate to drive the belt a (43) and the belt b (44) to rotate, and different transmission speeds are formed between the belt a (43) and the belt b (44), resulting in a differential effect, and the Aigen rolls between the belts to complete the initial separation;

[0020] (3) By adjusting the tensioning device, the tension of the belt and the gap of the separator are controlled so that the Aigen does not slip during the separation process and is transmitted smoothly.

[0021] The method comprises a step of further adjusting the gap, wherein the positions of the slider a (34) and the slider b (35) are controlled by adjusting the bolt (40) and the adjusting frame (42), thereby changing the gap size between the belt a (43) and the belt b (44) to adapt to the separation of wormwood of different sizes.

[0022] Furthermore, during the separation process, the soft iron sheets on the brush plates a (45) and b (46) are in contact with the belt surface to prevent the leakage of the Artemisia selengensis and ensure the normal operation of the machine to ensure the stability of sowing.

[0023] Furthermore, by adjusting the tension bolt a (12) and the tension bolt b (13), the tension of the tension roller a (28) and the tension roller c (31) is controlled to ensure the smooth operation of the belt a (43) and the belt b (44), so as to achieve continuous and efficient Aigen separation operation.

[0024] Beneficial effects of the present invention:

[0025] First, the gap adjustment device of the present invention is conducive to the automatic control of the gap, and then the control of the amount of wormwood seeding; when adjusting the gap, the two belts are at different inclination angles, which can ensure that the height of the two driven shafts is consistent, and further achieve accurate control of the amount of wormwood seeding. The differential belt wormwood orderly separator of the present invention can adapt to wormwood with complex material characteristics, and can achieve the separation of wormwood by using the relative movement of the two belts.

[0026] The differential belt type Aigen orderly separator of the present invention is provided with a seed brush a on the housing a and the housing b, which can effectively clean the seeds at the end of the belt and prevent the seed box from leaking. The differential belt type Aigen orderly separator of the present invention has a reference significance for the separation and seeding of similar seeds.

[0027] Second, the technical solution of the present invention significantly solves the following problems existing in the prior art through the innovatively designed differential belt Aigen orderly separator:

[0028] 1. The problem of entanglement of mugwort root: In the existing mugwort root sowing technology, mugwort root is easily entangled in the seeder, resulting in low separation efficiency and affecting the sowing quality. The present invention realizes orderly separation of mugwort root by using the differential speed transmission between belt a (43) and belt b (44) through the structural design of the differential belt, avoids the problem of entanglement of mugwort root, and greatly improves the separation efficiency.

[0029] 2. Gap adjustment problem: The gap adjustment of the separator in the prior art is not flexible and is difficult to adapt to moxa roots of different sizes and shapes. The present invention realizes flexible adjustment of the separator gap by setting the slider a (34) and the slider b (35) and the cooperation of the guide shaft, which can adapt to moxa roots of different sizes and improve the adaptability and sowing effect of the device.

[0030] 3. Leakage problem: In the existing mugwort seeding machine, seeds are easily leaked from the device, resulting in waste. The present invention effectively blocks excess mugwort by arranging soft iron sheets on the brush plates a (45) and b (46) inside the device, thereby preventing leakage and ensuring uniformity of seeding.

[0031] 4. Sowing efficiency: The present invention adopts a differential belt transmission method, which increases the friction between the belt and the mugwort root, ensuring that the mugwort root can be separated and sown faster and more evenly, greatly improving the sowing efficiency. Through the combination of the tensioning device and the gap adjustment device, the present invention can adapt to different working conditions and requirements, and has significant technical progress.

[0036] 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.

[0037] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0038] like Figure 2 As shown, the seed box serves as a container for filling the Artemisia argyi.

[0039] like Figure 1As shown, casing a2, casing b3, casing c4, and casing d5 are fixed by fasteners. Casing a2 and casing b3 are provided with a number of threaded holes, and screws are used to fix the bearing end cover 8, bearing end cover 9, support seat, etc. on their surfaces.

[0040] like Figure 1 and Figure 2 As shown, a slider a34 is installed on the support seat 22 and the support seat 36. When the nut on the adjustment frame 42 on the adjustment bolt 40 is tightened or loosened, the slider a and the slider b can move along the guide shaft a and the guide shaft b respectively. At this time, the support seat c20 and the support seat d21 on the slider a and the slider b will drive the driven shaft a14 and the driven shaft b17 fixed thereon to move, thereby adjusting the gap between the belt a43 and the belt b44.

[0041] like Figure 2 As shown, after the positions of the driven shaft a14 and the driven shaft b17 are determined, the belt a43 is tensioned by adjusting the position of the tensioning shaft a27, and the same is true for the belt b44.

[0042] like Figure 2 As shown, when the driving shaft a6 rotates counterclockwise, the belt a43 will move downward at a slower speed. When the driving shaft b7 rotates counterclockwise at a faster speed, the Aigen will roll inside the seed box 1 until it falls out of the gap. The rotation direction and rotation speed of the driving shaft a6 and the driving shaft b7 are not entirely based on what is described in this article and need to be adjusted appropriately according to actual working conditions.

[0043] The seed box 1 of the differential belt type Aigen orderly separator is located above the entire device and is used to store Aigen. The separator device is arranged in sequence below the seed box, including housing a2, housing b3, housing c4, and housing d5, which are connected to each other by bolts to form a stable overall frame structure. Belt a43 and belt b44 are respectively located inside the housing, and are staggered in the middle of the separator through their respective bearings and tensioning devices to ensure that Aigen can be evenly dispersed and separated from the upper seed box.

[0044] The driving shaft a6 is connected to the belt a43, and the transmission process is realized by driving the belt a. Similarly, the driving shaft b7 is connected to the belt b44 to drive the movement of the belt b. The two driving shafts are fixed by the bearing end cover a8 and the bearing end cover b9 respectively to ensure the stable operation of the shafts. At the same time, the tension is adjusted by the tension bolts a12 and the tension bolts b13 to further ensure the normal operation of the separator.

[0045] Slide block a34 and slide block b35 are installed on guide shaft a24 and guide shaft b25, and the gap between belt a and belt b is adjusted by sliding these guide shafts. The cooperation between the slide block and the guide shaft ensures the smooth flow of Aigen between the belts, and can adapt to different separation requirements by adjusting the position of the slide block. Support seat a10, support seat b11 and other components are installed on the slide block to further fix the position of the separation shaft.

[0046] The key function of the separator is to achieve orderly separation of the agarwood by using the different transmission speeds of the belts a43 and b44. The soft iron sheets on the brush plates a45 and b46 are in contact with the belt surface to block excess agarwood, prevent leakage and further sort the agarwood. During the separation process, the pattern on the belt increases the friction between the agarwood and the belt, ensuring improved separation efficiency. At the same time, the belt gap is adjusted to accommodate agarwood of different sizes, achieving a more refined separation effect.

[0047] The differential belt type orderly separator of mugwort of the present invention realizes orderly separation of mugwort through a double belt system with different transmission speeds, ensuring that the mugwort in the seed box can be evenly dispersed and gradually separated. The seed box 1 serves as the upper storage container of the device, and mechanically transmits the mugwort to the belt system of the separator device. The gap at the bottom of the seed box ensures that the mugwort gradually falls into the separator and is effectively separated on the belt system with different speeds.

[0048] Inside the separator, housing a2, housing b3, housing c4 and housing d5 are fastened to each other to form a stable frame. The driving shaft a6 is connected to the belt a43, driving the belt a to rotate counterclockwise at a relatively slow speed, while the driving shaft b7 is connected to the belt b44, driving the belt b to rotate counterclockwise at a faster speed. Due to the different speeds of the two belts, the aigen is evenly guided between the belts at the bottom of the seed box and gradually transported downward under the action of friction. In this process, the pattern on the belt increases the friction between the aigen and the belt surface, ensuring that the aigen can be driven stably.

[0049] Through the adjustment mechanism of slider a34 and slider b35, the gap between belt a and belt b can be finely adjusted to accommodate different sizes of aigins. The slider slides through guide shaft a24 and guide shaft b25 to change the belt gap to meet different separation requirements. Support seat a10, support seat b11 and other components fix the position of the slider and the driven shaft to ensure the stable operation of the belt system and prevent the slider from shifting during the adjustment process.

[0050] During the separation process, brush plates a45 and b46 contact the belt through soft iron sheets to effectively remove excess aigen and prevent excessive leakage. This structure not only ensures the orderliness of the separation, but also achieves efficient and precise separation through the difference in belt gap and transmission speed. Finally, aigen is evenly separated out of the device under the movement and adjustment of the belt, meeting the automated separation requirements of industrial production.

[0051] Example 1: Application in large-scale Artemisia argyi cultivation

[0052] In the process of large-scale mugwort planting, traditional manual sowing is time-consuming and labor-intensive, and the sowing quality is unstable. The differential belt mugwort orderly separator of the present invention solves the problems of mugwort entanglement and uneven sowing through precise mugwort separation and sowing. In a specific application, the present invention is installed on a tractor or automatic sowing equipment, and by adjusting the speed difference and gap adjustment device between belt a43 and belt b44, it is ensured that mugwort can be sown in an orderly manner according to the predetermined row spacing and plant spacing. The design of the slider and the guide shaft enables the equipment to flexibly adjust the sowing gap according to different land conditions and planting requirements, greatly improving the sowing efficiency. In a large-scale mugwort planting field, the use of this equipment can achieve an efficiency of dozens of acres of sowing area per hour, reducing labor costs and improving agricultural efficiency.

[0053] Example 2: Application of driving method

[0054] The power provided by the tractor PTO is usually strong and suitable for large-scale and high-intensity operations. This differential belt type Aigen orderly separator can use the power of the tractor to complete fast and efficient sowing, especially in agricultural production with a large area of ​​land, which can greatly improve the working efficiency. In addition, the differential belt type Aigen orderly separator can use the power of the tractor and drive it with a motor to achieve higher sowing accuracy and uniformity.
