Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to a portable seeding device. Background Technology

[0002] Seeding equipment is planting machinery that uses crop seeds as the agitator, and it is widely used in modern agricultural planting operations. Depending on the sowing requirements of different crops, seeding equipment can be divided into various types, such as grain row seeders, corn hill seeders, cotton seeders, and pasture broadcasters. The core function of these devices is to accurately and efficiently sow seeds into the soil to ensure good germination rates and uniform crop growth.

[0003] Currently available seeders and seeding equipment generally suffer from the following pain points: they employ an integrated design with a non-separable fan assembly, and most are wheeled. This design results in bulky and heavy equipment, requiring operators to exert considerable effort to push it along the ground. Especially in complex terrain conditions such as small plots of land, mountainous areas, and terraced gardens, existing seeding equipment appears cumbersome and inconvenient, making it difficult to operate flexibly and causing significant inconvenience for individual users' small-scale seeding operations.

[0004] Therefore, there is an urgent need to provide a portable seeding device to solve the above problems. Summary of the Invention

[0040] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0041] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

It should also be understood that additional or alternative steps may be used.

[0042] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence.

Therefore, the example term "below" can include both upper and lower orientations.

[0044] Figure 1 A schematic diagram of the structure of a portable seeding device according to an embodiment of the present invention is shown. Figure 2 A schematic cross-sectional view of a portable seeding device according to an embodiment of the present invention is shown. Figure 1 and Figure 2 As shown, the present invention proposes a portable seeding device, including a discharge structure 100 and a blower structure 200. The discharge structure 100 includes a storage bin 110 and a discharge pipe 120. The storage bin 110 has a discharge port 111a, and the side wall of the discharge pipe 120 is provided with an installation port. One end of the storage bin 110 with the discharge port 111a is connected to the discharge pipe 120 through the installation port, and the storage bin 110 is connected to the discharge pipe 120 through the discharge port 111a. One end of the discharge pipe 120 is the material outlet end, and the other end is the connection end. The blower structure 200 includes a housing 210 and a fan assembly 220. The fan assembly 220 is disposed inside the housing 210. One end of the housing 210 is the air inlet end, and the other end is the connection end. The connection end of the housing 210 is detachably connected to the connection end of the discharge pipe 120. The air inlet end of the housing 210 is used for air intake, and the fan assembly 220 is used for blowing air towards the material outlet end.

[0045] When using the portable seeding equipment provided in this technical solution for seeding operations, the material (various seeds or other similar granular materials) first enters the discharge pipe 120 from the internal space of the storage bin 110 through the discharge port 111a. Driven by the airflow of the fan assembly 220, it is then blown out from the material outlet end along the discharge pipe 120. The portable seeding equipment in this technical solution adopts a detachable connection between the discharge structure 100 and the blower structure 200, achieving miniaturization of the seeding equipment. During use, the operator can hold the portable seeding equipment to spread the material. Due to its lightweight, flexible, and simple operation, the portable seeding equipment provided in this technical solution can be applied to various small-scale or precision seeding scenarios, such as home planting, small farms, horticultural operations, and special terrain.

[0046] Furthermore, the portable seeding device is a handheld portable seeding device. Therefore, a first handle 123 is provided on the outer wall of the discharge pipe 120, and a second handle 211 is provided at the rear of the housing 210. The portable seeding device can be easily held in the hand through the first handle 123 and the second handle 211, and the operator can hold the portable seeding device while spreading the material.

[0047] When the portable seeding equipment is put into operation, the operator needs to simultaneously start the fan assembly 220 and the drive unit 140 to ensure the coordinated operation of the entire system. Once the material is successfully discharged from the storage bin 110, the fan assembly 220 immediately takes effect, blowing the material through the discharge pipe 120 with a powerful airflow, thus achieving uniform material distribution. The discharge direction of the storage bin 110 is perpendicular to the axis of the discharge pipe 120. This design ensures that the direction in which the material falls from the storage bin 110 is perpendicular to the airflow direction of the fan assembly 220, allowing the material to move smoothly along the discharge pipe 120 under the influence of the airflow and ultimately be blown out from the material outlet. Optionally, the fan assembly 220 can be an axial flow fan assembly 220. The axial flow fan assembly 220 delivers air axially, suitable for scenarios requiring high flow rates and low to medium pressure, with lower energy consumption. Under the same airflow, the axial flow fan assembly 220 typically consumes less energy than the centrifugal fan assembly 220 and has a more advantageous manufacturing cost. In other embodiments, the fan assembly 220 may also be a centrifugal fan assembly 220 or a mixed-flow fan assembly 220, etc.

[0048] See also Figure 1 and Figure 2The discharge pipe 120 and the housing 210 are connected by an insertion joint. Optionally, the outer diameter of the discharge pipe 120's connecting end is larger than the outer diameter of the housing 210's connecting end, allowing the housing 210's connecting end to be inserted into the discharge pipe 120's connecting end. Further, a snap-fit ​​protrusion 213 is provided on the outer side of the housing 210's connecting end, and a rotatable button 124 is provided on the discharge pipe 120's connecting end. After the housing 210 is inserted into the discharge pipe 120, the part of the button 124 near the housing 210 presses against the snap-fit ​​protrusion 213. When it is necessary to separate the discharge structure 100 and the blower structure 200, pressing the end of the button 124 away from the housing 210 causes the other end of the button 124 to lift and move away from the snap-fit ​​protrusion 213, allowing the discharge pipe 120 to be pulled out of the housing 210. This connection method between the discharge structure 100 and the blower structure 200 makes the loading and unloading process very convenient and provides a good user experience.

[0049] Furthermore, Figure 3 A schematic diagram of the material discharge structure 100 according to an embodiment of the present invention is shown. Figure 4 A schematic cross-sectional view of the discharge structure 100 according to an embodiment of the present invention is shown. See also Figure 3 and Figure 4 The storage bin 110 includes a storage bin body 111 and a discharge pipe 112. The discharge pipe 112 is connected to the bottom of the storage bin body 111. The bottom of the storage bin body 111 is provided with a connecting port 111c. The storage bin body 111 is connected to the discharge pipe 112 through the connecting port 111c.

[0050] Optionally, the storage silo body 111 adopts a rectangular opening in its structural design. This opening not only facilitates the entry and exit of materials but also improves storage efficiency. Its bottom roughly presents a pyramidal geometric shape, which helps in the concentration and discharge of materials. To ensure that materials are not obstructed by sharp corners during flow, rounded corners are used, making the internal structure of the entire storage silo body 111 smoother and more fluid. The ingeniously designed inclined sidewalls of the storage silo body 111 effectively guide materials downwards along the sidewalls, thus largely preventing material accumulation and ensuring that the materials inside the storage silo 110 maintain good flowability. Furthermore, optionally, the bottom sidewall of the storage silo body 111 is specially designed with a greater inclination than the middle sidewall. This differentiated inclination design further enhances material flowability, allowing materials to move more smoothly downwards under gravity, reducing discharge problems caused by material accumulation. In other embodiments, the storage silo body 111 may also adopt different structural forms, such as a circular opening design with a conical bottom. This combination of a circular opening and a conical bottom can also effectively promote the flow and discharge of materials.

[0051] Optionally, the drive unit 140 can be a servo motor, a variable speed motor, or a pneumatic motor. Servo motors are suitable for precision seeding scenarios requiring variable speed control, with a positioning accuracy of ±0.1°; variable frequency speed motors are an economical option, with an adjustable speed range of 50-300 rpm, suitable for most field crops; pneumatic motors feature an explosion-proof design, making them particularly suitable for conveying easily dusty materials such as organic fertilizers.

[0052] See also Figure 3 and Figure 4 The discharge pipe 120 has an installation port on its side wall. The storage hopper 110 is connected to the discharge pipe 120 through the installation port, and the discharge pipe 112 is inserted into the installation port. Further, the outer wall of the discharge pipe 120 is provided with an extension plate 122, which is positioned along the outer periphery of the installation port. The bottom of the storage hopper 110 is provided with a connecting plate 115, located on the outer periphery of the discharge pipe 112, and the connecting plate 115 is inserted into the extension plate 122. The discharge pipe 120 and the storage hopper 110 are connected via the extension plate 122 and the connecting plate 115, resulting in a compact overall structure and a stable connection. In other embodiments, the discharge pipe 120 and the storage hopper 110 can also be connected using bolts 180. Optionally, a sealing gasket can be provided between the extension plate 122 and the connecting plate 115 to increase the stability of the connection. Alternatively, the extension plate 122 and the connecting plate 115 can be fixedly connected by adhesive or by connecting bolts 180.

[0053] To further improve the material spreading effect, the discharge pipe 120 features a constricted design at the discharge port 121. This constricted design not only effectively converges the airflow, enhancing its concentration and intensity, but also ensures that the material does not disperse or become blocked during discharge, allowing it to exit the discharge port 121 more smoothly and efficiently, achieving the desired spreading effect. Specifically, along the discharge direction, the cross-sectional shape of the discharge pipe 120 gradually transitions from circular to flattened oval.

[0054] Further, see Figure 4 The diameter of the connecting port 111c is smaller than the inner diameter of the discharge pipe 112.

[0055] Understandably, by limiting the size of the connecting port 111c, the flow rate of material at the connecting port 111c can be limited. Therefore, making the diameter of the connecting port 111c smaller than the inner diameter of the discharge pipe 112 can effectively prevent material from getting stuck in the discharge pipe 112. In other embodiments, the diameter of the connecting port 111c may also be the same as the inner diameter of the discharge pipe 112.

[0056] Figure 5 A partial exploded view of the discharge structure 100 according to an embodiment of the present invention is shown schematically. See also Figure 4 and Figure 5 The storage bin 110 is equipped with a screw component 130 and a drive component 140. The fixed end of the drive component 140 is connected to the inner wall of the storage bin 110, and the output end of the drive component 140 is connected to the screw component 130. The drive component 140 is used to drive the screw component 130 to rotate, and the screw component 130 is used to convey materials.

[0057] During the discharge process, the material inside the storage bin 110 is driven by the screw 130 to begin rotating and is gradually discharged. By installing the screw 130 inside the storage bin 110, not only can the smooth discharge of material from the storage bin 110 be significantly promoted, but the accumulation of material inside the storage bin 110 can also be effectively reduced. In this way, the jamming of material inside the storage bin 110 is fundamentally avoided, thereby greatly reducing the possibility of unexpected interruptions during the sowing process. In addition, the material conveying by the screw 130 can also ensure the uniformity of the material during the flow process. Specifically, this design can prevent small particles from falling prematurely due to their own weight and other factors, while also preventing large particles from being delayed in discharge due to greater frictional resistance. In this way, both small and large particles can be discharged synchronously and evenly during the sowing process, resulting in a more uniform sowing density. Because this portable sowing equipment demonstrates excellent smoothness and uniformity in sowing operations, it can not only meet the sowing needs of a single crop, but also flexibly cope with the sowing requirements of different types of crops. This wide applicability makes the portable seeding device highly practical and has broad application prospects in agricultural production.

[0058] Optionally, the auger 130 passes through the discharge pipe 112, with its top extending into the storage hopper body 111 via the connecting port 111c. The drive unit 140 is located inside the storage hopper body 111, with its fixed end connected to the storage hopper body 111 and its output end connected to the auger 130 to drive its rotation. To match the structure of the auger 130, the discharge pipe 112 is designed as a circular pipe, ensuring smooth material flow during discharge and improving discharge efficiency. Correspondingly, the connecting port 111c is also designed as a circular hole to match the circular structure of the discharge pipe 112, ensuring the coordination and efficiency of the entire storage and discharge system.

[0059] Further, see Figure 5 The spiral component 130 includes a connecting shaft 131 and a spiral blade 132. The spiral blade 132 is spirally distributed along the length of the connecting shaft 131, and the end face of the spiral blade 132 and the side wall of the connecting shaft 131 form a spiral guide groove 132a.

[0060] In this technical solution, the spiral component 130, together with the connecting shaft 131 and the spiral blades 132, forms a highly efficient material conveying channel. The spiral guide groove 132a formed by the end face of the spiral blades 132 and the side wall of the connecting shaft 131 generates centripetal acceleration in the material during conveying, effectively guiding the material to gather towards the axis. The connecting shaft 131, as the core support structure, can be made of high-strength alloy steel or wear-resistant stainless steel to ensure structural stability under long-term high-speed operation. The spiral blades 132 are fixed to the outer surface of the connecting shaft 131 by welding or integral molding. Their helix angle has been optimized by hydrodynamics and can be adjusted within the range of 30° to 45° to adapt to the friction coefficient and flowability requirements of different materials.

[0061] Understandably, the length of the connecting shaft 131 is set according to the usage requirements. In this embodiment, the top of the connecting shaft 131 extends from the communication port 111c, thereby facilitating connection with the drive member 140, and the bottom of the connecting shaft 131 extends from the bottom of the discharge pipe 112, so that the connecting shaft 131 has sufficient length to arrange the helical blade 132.

[0062] Optionally, a positioning groove 131a is provided at the top of the connecting shaft 131, and a connecting protrusion 141 is provided at the output end of the driving member 140. The connecting protrusion 141 and the positioning groove 131a are inserted into each other, thereby realizing the connection between the connecting shaft 131 and the driving member 140. It can be understood that the cross-sectional shape of the positioning groove 131a is non-circular, and the shape of the connecting protrusion 141 is set according to the shape of the positioning groove 131a, so as to ensure that the driving member 140 can drive the connecting shaft 131 to rotate. In this embodiment, the cross-sectional shape of the positioning groove 131a is cross-shaped. In other embodiments, the cross-sectional shape of the positioning groove 131a can also be rectangular, oblong, or arc-shaped, etc.

[0063] Furthermore, Figure 6 A schematic diagram of the storage silo 110 according to an embodiment of the present invention is shown from a certain perspective. See also Figure 4 , Figure 5 and Figure 6 The discharge structure 100 also includes a fixed base 160. A connecting column 114 is connected to the bottom of the storage bin body 111. The fixed base 160 and the connecting column 114 are fixedly connected. The end of the spiral component 130 away from the driving component 140 is rotatably connected to the fixed base 160.

[0064] The fixed base 160 provides support for the spiral component 130 and increases its stability, preventing it from shifting during rotation. Optionally, the fixed base 160 includes a base plate 161 and a connecting portion 252 connected to the base plate 161. A groove is formed in the center of the connecting portion 252. A bearing 170 is disposed inside the groove, fitted onto the bottom of the connecting shaft 131. The inner ring of the bearing 170 is fixedly connected to the connecting shaft 131, and the outer ring of the bearing 170 is fixedly connected to the inner wall of the connecting portion 252. Understandably, by providing the bearing 170 between the connecting shaft 131 and the connecting portion 252, the sliding friction between the connecting shaft 131 and the mounting portion 162 is converted into rolling friction, effectively reducing frictional resistance and energy consumption. Simultaneously, it effectively prevents the connecting shaft 131 from wobbling radially or axially, ensuring smooth rotation and extending the overall service life.

[0065] Optionally, the connecting part 252 and the base plate 161 are integrally formed. The base plate 161 has a through hole for a bolt 180 to pass through, and the connecting post 114 has a cavity. The inner wall of the cavity has threads for connection with the bolt 180. The base plate 161 is connected to the connecting post 114 via the bolt 180. In this embodiment, two connecting posts 114 are provided, located outside the discharge pipe 112 and at opposite ends of the length of the fixing base 160. In other embodiments, the number of connecting posts 114 can be three, four, or five, depending on the specific application requirements.

[0066] Furthermore, Figure 7 A schematic diagram of the storage silo 110 according to an embodiment of the present invention is shown from another perspective. See also Figure 7 The storage bin 110 is equipped with an installation frame 113. The installation frame 113 includes a fixing ring 113a and a connector 113b. The fixing ring 113a and the connecting port 111c are spaced 111b apart. The connector 113b connects the outer wall of the fixing ring 113a to the inner wall of the storage bin 110. The top of the spiral member 130 passes through the fixing ring 113a and is rotatably connected to the fixing ring 113a. The output end of the driving member 140 passes through the fixing ring 113a and the fixed end of the driving member 140 is connected to the fixing ring 113a.

[0067] Understandably, the mounting bracket 113 should be able to stably support the fixed drive component 140, while also allowing space for material flow so that the material can pass smoothly through the connecting port 111c. Optionally, the connector 113b is a plate-like structure. The connector 113b connects the fixing ring 113a and the storage hopper body 111, and also increases the structural strength of the storage hopper body 111. Optionally, there can be one or more connectors 113b. In this technical solution, there are four connectors 113b. In other embodiments, there can be two, three, or five connectors 113b, depending on the specific application requirements. Understandably, the gap 111b between the fixing ring 113a and the connecting port 111c is connected to the connecting port 111c, allowing material to flow out along the discharge pipe 112 through the gap 111b and the connecting port 111c.

[0068] Furthermore, a bearing 170 is fitted onto the connecting shaft 131. The inner ring of the bearing 170 is fixedly connected to the connecting shaft 131, and the outer ring of the bearing 170 is fixedly connected to the side wall of the retaining ring 113a. Understandably, by providing the bearing 170 between the connecting shaft 131 and the retaining ring 113a, the sliding friction between them is converted into rolling friction, effectively reducing frictional resistance and energy consumption. Simultaneously, it effectively prevents the connecting shaft 131 from wobbling radially or axially, ensuring smooth rotation and extending the overall service life.

[0069] Furthermore, Figure 8 A schematic diagram of the structure of a protective cover 150 according to an embodiment of the present invention is shown. See also Figure 8 The discharge structure 100 also includes a protective cover 150, which includes a protective cover body 151 and an extension 152. The protective cover body 151 covers the bottom of the drive member 140, and the extension 152 is connected to the connector 113b.

[0070] The protective cover 150 serves to protect the drive component 140. The protective cover body 151 has a receiving groove 154 for accommodating the drive component 140. Support ribs 153 are provided on the inner wall of the receiving groove 154. On one hand, the support ribs 153 reinforce the structure of the protective cover 150; on the other hand, the support ribs 153 abut against the outer side of the drive component 140, thus providing good support and fixation. Since the connector 113b has a plate-like structure, the extension 152 is designed as a strip structure, and the extension 152 has a strip groove 155 with an opening facing the connector 113b. Therefore, the extension 152 can be fastened to the connector 113b, and the connector 113b is engaged in the strip groove 155, increasing the connection strength between the protective cover 150 and the mounting bracket 113. The protective cover body 151 and the extension 152 can be integrally formed. The protective cover 150 can be made of engineering plastics, such as ABS plastic, polycarbonate, or nylon. The protective cover 150, made of engineering plastics, is lightweight and easy to injection mold. It is also insulating, rust-proof, and unlikely to generate sparks upon impact, ensuring high safety. The protective cover 150 can also be made of metal, such as aluminum alloy or stainless steel. The protective cover 150 made of metal has the advantages of high mechanical strength, strong protection, and high temperature resistance, making it suitable for long-term, high-load operation.

[0071] Figure 9 A schematic diagram of the blower structure 200 according to an embodiment of the present invention is shown. Figure 10 A schematic cross-sectional view of the blower structure 200 according to an embodiment of the present invention is shown. Figure 11 yes Figure 10 A magnified view of a portion at point A. See also... Figure 9 , Figure 10 and Figure 11 The housing 210 is equipped with a controller 230 and a socket 240. The fan assembly 220 and the socket 240 are electrically connected to the controller 230. The drive unit 140 is connected to a plug 190 via a wire. When the housing 210 and the discharge pipe 120 are connected, the plug 190 and the socket 240 are plugged in.

[0072] The controller 230 is used to control the operation of the fan assembly 220 and the drive unit 140. Since the controller 230 is located inside the housing 210, the drive unit 140 can be connected to the controller 230 via a plug 190 and a socket 240. The fan assembly 220 and the drive unit 140 share a single controller 230 and a single power supply, resulting in a compact overall structure and convenient control for the portable seeding equipment. Furthermore, because the housing 210 and the discharge pipe 112 are connected by a plug-in connection, the plug 190 and socket 240 can be plugged in simultaneously when connecting the housing 210 and the discharge pipe 112.

[0073] Further, see also Figure 10 The housing 210 has a battery compartment 212 inside, which is used to hold a battery that powers the controller 230, fan assembly 220 and drive unit 140.

[0074] The battery can be a primary or secondary battery. Optionally, the controller 230 is directly powered by the battery, and the fan assembly 220 and drive unit 140 are controlled by the controller 230 via a relay or drive circuit. The battery powers the fan assembly 220 and drive unit 140 directly or after voltage reduction. Further, the portable seeding device is equipped with a power switch 291. Pressing the power switch 291 connects the battery and the controller 230, allowing control of the fan assembly 220 and drive unit 140 via the controller 230. Optionally, the power switch 291 is located above the second handle 211. In other embodiments, the power switch 291 may also be located in other positions on the housing 210.

[0075] Furthermore, Figure 12 A partial exploded view of the blower structure 200 according to an embodiment of the present invention is shown schematically. See also Figure 12 The fan assembly 220 includes a dual-axis motor 221, a first fan 222, and a second fan 223. The dual-axis motor 221 is electrically connected to the controller 230. The first fan 222 and the second fan 223 are respectively connected to the two output shafts of the dual-axis motor 221. The first fan 222 is closer to the discharge port 111a than the second fan 223. The outer diameter of the first fan 222 is smaller than the outer diameter of the second fan 223, and the air outlet direction of both the first fan 222 and the second fan 223 is towards the material outlet end.

[0076] The first fan 222 and the second fan 223 can promote the discharge of materials from the discharge pipe 120. Furthermore, the first fan 222 is located close to the discharge port 111a. The first fan 222 can concentrate the airflow to the material discharged from the discharge pipe 112, thereby increasing the discharge efficiency.

[0077] Further, see also Figure 12 A flow collector 250 is provided between the first fan 222 and the discharge port 111a. The flow collector 250 includes a connecting part 252 and a flow collector 251 that are connected to each other. The flow collector 251 is connected to the housing 210 through the connecting part 252. The first fan 222 is directly opposite the air inlet end of the flow collector 251. The inner diameter of the air outlet end of the flow collector 251 is larger than the inner diameter of the air inlet end of the flow collector 251.

[0078] By using the converging design of the flow collector 251, the airflow can be gathered below the discharge port 111a, concentrating and dispersing the falling material. Optionally, the connecting part 252 is annular and sleeved on the outer periphery of the flow collector 251. The connecting part 252 and the flow collector 251 are connected by multiple sheet-like structures spaced 111b apart, thereby forming an airflow channel between the connecting part 252 and the flow collector 251. The airflow from the first fan 222 can be blown from the airflow channel towards the material.

[0079] Furthermore, the blower structure 200 also includes an air inlet hood 270, a connecting hood 280, and a guide hood 260 connected sequentially along the airflow direction. The air inlet hood 270 is a hollow structure located behind the housing 210 and is used for air intake. The connecting hood 280 is used to connect the air inlet hood 270 and the guide hood 260. From the air intake to the air outlet direction, the inner diameter of the connecting hood 280 gradually decreases, thereby increasing the air intake volume. Optionally, the guide hood 260 includes an inner ring and an outer ring, with multiple guide vanes arranged at a interval 111b between the inner and outer rings. The inner ring is sleeved on the outer periphery of the drive member 140, and the outer ring is fixedly connected to the housing 210. Understandably, the arrangement of the guide hood 260 allows the airflow blown by the first fan 222 to be evenly dispersed in the air outlet pipe, thereby effectively increasing the material distribution area.

[0080] Example 1

[0081] Figure 13 The principle of a portable seeding device according to an embodiment of the present invention is illustrated schematically. Figure 1 See also Figure 13 In this embodiment, the portable seeding device also includes a control switch. The fan assembly 220 and the drive unit 140 are both electrically connected to the control switch, which is used to control the operation of the fan assembly 220 and the drive unit 140.

[0082] Furthermore, after the operator triggers the control switch, the controller 230 simultaneously supplies power to the fan assembly 220 and the drive unit 140. The fan assembly 220 operates at a preset constant speed to ensure stable airflow output. The drive unit 140 monitors its operating status (such as speed, position, or load) in real time and feeds the signal back to the controller 230, forming a closed-loop control. The operator can adjust the rotation speed of the auger 130 by adjusting the operation of the drive unit 140 through the control switch, thereby adjusting the material falling speed. When the rotation speed of the auger 130 increases, the material falling speed increases; when the rotation speed of the auger 130 decreases, the material falling speed decreases. By adjusting the material discharge speed, the seeding density can be adjusted.

[0083] Example 2

[0084] Figure 14 The principle of a portable seeding device according to an embodiment of the present invention is illustrated schematically. Figure 2 See also Figure 14 In this embodiment, the portable seeding device also includes a control switch. The fan assembly 220 and the drive unit 140 are both electrically connected to the control switch, which is used to control the operation of the fan assembly 220 and the drive unit 140.

[0085] Furthermore, after the operator triggers the control switch, the controller 230 simultaneously supplies power to the fan assembly 220 and the drive unit 140. The drive unit 140 feeds back a signal to the controller 230, which then inputs a fixed current to the drive unit 140 to make it rotate at a constant speed. The operator controls the speed of the fan assembly 220 via the control switch. When the fan assembly 220 is running at a high speed, the material is discharged quickly and falls to a position farther from the operator; when the fan assembly 220 is running at a low speed, the material is discharged slowly and falls to a position closer to the operator. Therefore, the distribution position of the material can be controlled by controlling the speed of the fan assembly 220.

[0087] Figure 15 The principle of a portable seeding device according to an embodiment of the present invention is illustrated schematically. Figure 3 See also Figure 15 In this embodiment, the portable seeding device also includes a control switch. The fan assembly 220 and the drive unit 140 are both electrically connected to the control switch, which is used to control the operation of the fan assembly 220 and the drive unit 140.

[0088] Furthermore, after the operator triggers the control switch, the controller 230 simultaneously supplies power to the fan assembly 220 and the drive unit 140. Both the fan assembly 220 and the drive unit 140 operate at a constant speed.

[0089] Example 4

[0090] Figure 16 The principle of a portable seeding device according to an embodiment of the present invention is illustrated schematically. Figure 4 Further, see Figure 16 The portable seeding device also includes a first control switch 292 and a second control switch 293. The first control switch 292 is electrically connected to the drive unit 140 and is used to control the operation of the drive unit 140. The second control switch 293 is electrically connected to the fan assembly 220 and is used to control the operation of the fan assembly 220.

[0091] Furthermore, the first control switch 292 controls the operating speed of the fan assembly 220 via the controller 230, thereby adjusting the airflow. The second control switch 293 controls the operating speed of the drive component 140 via the controller 230, thereby adjusting the feeding speed. The first control switch 292 controls the material's falling speed, thus controlling the sowing density, while the second control switch 293 controls the material's discharge speed, thus controlling the material's landing position. Therefore, this method gives the portable sowing equipment wide adjustability, making it more versatile.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
