Description

Technical Field

[0001] This invention belongs to the field of agricultural sowing and seedling raising, and specifically relates to an automated seedling raising and sowing machine. Background Technology

[0002] Currently, there are various methods of artificially cultivated crops, including direct seeding, transplanting, and cutting propagation, with transplanting accounting for the majority. Transplanting involves the centralized cultivation of seedlings before transplanting them to the field, which has many advantages. For example, it facilitates centralized and meticulous management during the seedling stage, promoting uniform and robust seedlings; seedling cultivation can be carried out indoors or in greenhouses, allowing for earlier sowing; and seedlings can be sown and cultivated earlier in greenhouses when external conditions are not yet conducive to seedling emergence; furthermore, seedlings can be cultivated in different locations before the previous season's crop matures and harvested, and then transplanted after the previous season's crop is harvested, thus ensuring a smooth transition between the two seasons.

[0003] Existing seedling raising equipment is semi-automatic and cannot automatically complete the entire seedling raising process, including sowing, watering, and covering with soil. Manual loading, unloading, and transfer of seedling trays are still required. Furthermore, in semi-automatic equipment, the seedling trays are moved vertically up and down, meaning the entire weight of the trays is borne by the equipment's chain. A single seedling unit carries hundreds of seedling frames and trays, and the entire weight of the soil, water, seeds, or seedlings in the trays is borne by this single chain. This excessive load not only limits the number of trays it can support but also makes it extremely prone to chain breakage and accidents, and repairing the connection is very difficult.

[0004] To address the aforementioned problems, this invention provides an automated seedling raising and sowing machine that can automatically complete the entire seedling raising and sowing process, including sowing, watering, and covering with soil, while also reducing the load on the chain throughout the process. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an automated seedling raising and planting machine, including a control terminal, and further including a closed-loop transfer structure and a traveling seeding structure electrically connected to the control terminal.

The power assembly is electrically connected to the control terminal, and the closed-loop feeding chain is housed within the load-bearing plate.

[0010] Furthermore, the chain assembly is a closed-loop multi-layer horizontal chain.

[0011] Furthermore, the sowing structure includes a soil-adding structure, a sowing hopper, a water-fertilizer-adding structure, a topsoil-covering structure, and a soil conveyor, which are sequentially arranged on the movable frame. The side of the soil-adding structure is connected to the side of the topsoil-covering structure. The sowing hopper and the water-fertilizer-adding structure are located between the soil-adding structure and the topsoil-covering structure. The soil conveyor is obliquely arranged on the movable frame. The connection between the soil-adding structure and the topsoil-covering structure is spatially parallel to the discharge end of the soil conveyor.

[0012] Furthermore, the soil-adding structure, the seeding hopper, and the topsoil-covering structure are identical in structure; the soil-adding structure includes a hopper body, a lifting structure, a drive source, a roller drum, an inductive switch, and a metering sensor.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Figure 1 A structural schematic diagram according to an embodiment of the present invention is shown. Figure 1 As shown, an automated seedling raising and sowing machine includes a control terminal 1, and also includes a closed-loop transfer structure and a walking sowing structure 5 electrically connected to the control terminal 1. The closed-loop transfer structure includes a frame 2, a load-bearing plate 3, and a horizontal transfer component 4. The load-bearing plate 3 and the horizontal transfer component 4 are both mounted on the frame 2. The load-bearing plate 3 and the horizontal transfer component 4 are in rolling contact. The load-bearing plate 3 bears the weight of the horizontal transfer component 4. The walking sowing structure 5 includes a movable carrier 51 detachably connected to the frame 2. The movable carrier 51 is provided with a sowing structure for sowing seeds onto the horizontal transfer component 4.

[0040] The automated seedling raising and sowing machine controls the closed-loop transfer structure and the walking sowing structure 5 through the control terminal 1 to complete the sowing, which is more intelligent. The load-bearing plate 3 is used to bear the weight of the horizontal transfer component 4 and transfer the weight to the frame 2 to avoid chain breakage accidents.

[0041] Specifically, control terminal 1 is optional but not limited to a computer.

[0042] In some embodiments, the frame 2 includes a support 22 and a propagation frame 21. The propagation frame 21 is provided on the side of the support 22 near the mobile carrier 51. The propagation frame 21 and the support 22 are provided with the same load-bearing plate 3. The propagation frame 21 and the support 22 are provided with the same horizontal transfer component 4. The end of the propagation frame 21 away from the support 22 is detachably connected to the mobile carrier 51. The support 22 and the propagation frame 21 are used to support the weight of the load-bearing plate 3 and the horizontal transfer component 4. The propagation frame 21 provides a sowing area for the horizontal transfer component 4 and the sowing structure.

[0043] In some embodiments, the mobile carrier 51 includes a microcontroller 515 electrically connected to the control terminal 1, a mobile component, a mobile frame 513, and an environmental sensor 516. The microcontroller 515, the mobile component, and the environmental sensor 516 are all mounted on the mobile frame 513.

The mobile frame 513 is provided with a sowing structure for sowing seeds to the horizontal transfer components 4. After the walking sowing structure 5 completes sowing to a closed-loop transfer structure, the control terminal 1 sends information to the microcontroller 515, causing the mobile component to move the mobile frame 513 to another set of horizontal transfer components 4 according to a preset route for over-sowing. This process is repeated until the preset multiple sets of horizontal transfer components 4 have been sown. The environmental sensor 516 can monitor the surrounding environment and route and send information to the microcontroller 515 in real time.

[0044] Specifically, the environmental sensing element 516 is optional but not limited to a sensor.

[0045] Specifically, the 515 microcontroller is existing technology, so it will not be discussed further here.

[0046] In some embodiments, the moving component includes a moving wheel set 511 and a moving source 512. Both the moving wheel set 511 and the moving source 512 are mounted on the moving frame 51. The driving end of the moving source 512 is connected to the end of the moving wheel set 511, and the moving source 512 is electrically connected to a microcontroller 515. The moving source 512 is used to drive the moving wheel set 511 to roll, thereby achieving the purpose of moving the moving frame 51.

[0047] The specific mobile source 512 is optional but not limited to servo motors.

[0048] Figure 2 It shows Figure 1 A magnified view of a portion of A. (For example...) Figure 2 As shown, the detachable connection between the mobile carrier 51 and the propagation frame 21 is that the mobile carrier 51 is provided with a limiting angle 514, and the end of the propagation frame 21 away from the support 22 is in contact with the limiting angle 514. The mobile carrier 51 and the propagation frame 21 restrict each other through the limiting angle 514, ensuring the alignment of the sowing structure and the propagation frame 21, and ensuring sowing efficiency.

[0049] Specifically, the detachable connection between the mobile carrier 51 and the breeding rack 21 can also be achieved through screws and nuts, clips, etc.

[0050] In some embodiments, the horizontal transfer assembly 4 includes a chain assembly 41, a breeding frame 42, and a rolling assembly 43. The chain assembly 41 is connected to the frame 2, and the portion of the chain assembly 41 near the frame 2 is housed within a load-bearing plate 3. The breeding frame 42 is housed within the chain assembly 41, and the rolling assembly 43 is provided on the breeding frame 42. The end of the rolling assembly 43 away from the breeding frame 42 is connected to the chain assembly 41, and the rolling assembly 43 makes rolling contact with the load-bearing plate 3. The breeding frame 42 is connected to the chain assembly 41 through the rolling assembly 43, enabling the chain assembly 41 to drive the breeding frame 42 to move, and the rolling assembly 43 to transfer gravity to the load-bearing plate 3.

Figure 4 As shown, in some embodiments, the rolling assembly 43 includes a connecting plate 431, a connecting shaft 432, a roller 433, and a load-bearing shaft 434. Figure 3 It shows Figure 1 A magnified view of part B, as shown below. Figure 3 As shown, the connecting plate 431 is detachably connected to the breeding frame 42. A connecting shaft 432 is provided at the end of the connecting plate 431 away from the breeding frame 42. The end of the connecting shaft 432 away from the breeding frame 42 is connected to the chain assembly 41. A load-bearing shaft 434 is provided at the part of the connecting plate 431 near the connecting shaft 432. A roller 433 is provided at one end of the load-bearing shaft 434, which is housed within the load-bearing plate 3. The roller 433 makes rolling contact with the load-bearing plate 3. The rolling contact between the breeding frame 42 and the load-bearing plate 3 via the roller 433 reduces the load on the chain assembly 41 and prevents chain breakage. The connecting shaft 432 and the connecting plate 431 connect the breeding frame 42 and the chain assembly 41, allowing the chain assembly 41 to move the breeding frame 42. The load-bearing shaft 434 transfers the weight of the breeding frame 42 to the roller 433.

When one of the seed-distributing grooves 531 is aligned with the hopper body 521 of the sowing hopper 53, the seeds will fall from the seed-distributing groove 531 into the breeding frame 42, thus realizing sowing.

[0070] Specifically, the number of seeding furrows 531 can be varied depending on the specific circumstances.

[0071] In some embodiments, the hopper 521 is conical; this facilitates material discharge.

The nozzle 542 is provided on the water pipe 541 and is electrically connected to the control terminal 1. The electrical connection between the nozzle 542 and the control terminal 1 enables the nozzle 542 to receive instructions or preset instructions to open or close, thereby achieving the purpose of watering seeds.

The fixed base 5221 has a receiving groove 5222, and the driving source 523 is housed in the receiving groove 5222. The adjusting structure is threadedly connected to the fixed base 5221. One end of the adjusting structure, housed in the receiving groove 5222, contacts the driving source 523. The mounting base 5226 has a sliding groove 5227, and a slider 5228 is provided in the sliding groove 5227. The end of the slider 5228 away from the sliding groove 5227 is connected to the rolling cylinder 524. The fixed base 5221 is located on one side of the bucket body 521, and the mounting base 5226 is located on the side of the bucket body 521 away from the fixed base 5221. The fixed base 5221 is used to house the driving source 523 and also provides a lifting limit range for the lifting of the driving source 523. The adjusting structure can lift the driving source 523.

[0075] In some embodiments, the adjustment structure includes a lifting plate 5224 and a bolt 5225. The bolt 5225 is threadedly connected to the fixed seat 5221. The lifting plate 5224 is provided at one end of the bolt 5225, which is housed in the receiving groove 5222. The side of the lifting plate 5224 away from the bolt 5225 is in contact with the driving source 523. When the bolt 5225 rotates upward, the lifting plate 5224 lifts the driving source 523 upward, and the driving source 523 drives the rolling drum 524 to move upward, thereby reducing the amount of soil falling.

[0076] In some embodiments, the fixed base 5221 is provided with a threaded hole 5223 that passes through the receiving groove 5222; this facilitates the connection of bolts 5225 to achieve the purpose of lifting the drive source 523.

[0077] In some embodiments, the conveyor belt of the soil conveyor 56 is evenly distributed with multiple baffles 561, and adjacent baffles 561 and the conveyor belt located between adjacent baffles 561 form a soil storage trough 562; the adjacent baffles 561 can dig the soil accumulated on the ground into the soil storage trough 562 as the conveyor belt is conveyed, and the soil storage trough 562 can prevent the soil from slipping.

[0078] Specifically, the soil conveyor 56 is existing technology, so the specific structure of the soil conveyor 56 will not be described in detail here.

[0079] Figure 11 A system diagram of the control system for an automated seedling raising and sowing machine is shown. (For example...) Figure 11 As shown, a control system for an automated seedling raising and planting machine includes:

[0080] Transfer module: Used to support the weight of the horizontal transfer assembly 4 by bearing the load-bearing plate 3, and to provide support for the load-bearing plate 3 by using the frame 2;

[0081] Seeding module: used to sow seeds using the seeding structure and the horizontally conveying component 4;

[0082] Control module: Used to receive information from the horizontal transfer component 4 and the seeding structure and to provide corresponding instructions or preset instructions.

[0083] The working principle of the automated seedling raising and sowing machine is as follows:

[0084] Intelligent operation is achieved through electrical connection. The load on the closed-loop feeding chain 411 is reduced by the load-bearing plate 3, avoiding chain breakage accidents. Specifically, the walking seeding structure 5 is moved to the breeding rack 21 and connected to the breeding rack 21. Then, the control terminal 1 sends a command or preset command to the drive component to start the drive component, which in turn drives the transmission chain 415, the second sprocket assembly 413, and the first sprocket assembly 412 to rotate in sequence, thereby driving the closed-loop feeding chain 411 to move. During the transfer of the breeding frame 42, the closed-loop conveyor chain 411 transmits gravity to the load-bearing plate 3 via the load-bearing shaft 434 and rollers 433. The load-bearing plate 3 then transmits gravity to the support 22. The inductive switch 525 on the side wall of the soil-adding structure 52 determines the position of the breeding frame 42. When one end of the breeding frame 42 enters the discharge port of the soil-adding structure 52, the inductive switch 525 feeds back the collected information to the control terminal 1. The control terminal 1 then feeds back the information to the drive source 523, which drives the roller drum 524 to rotate and discharge soil, laying the bottom soil on the breeding frame 42. As the breeding frame 42 moves out of the discharge port of the soil-adding structure 52, the inductive switch 525 feeds back the collected information to the control terminal 1, which then feeds back the information to the drive source 523. The drive source 523 shuts off, and the soil-adding structure 52 stops discharging soil. As one end of the breeding frame 42 enters the discharge port of the seeding hopper 53, the inductive switch 525 sequentially passes through the inductive switch on the seeding hopper 53. Information is transmitted between the switch 525, control terminal 1, and drive source 523 on the seeding hopper 53, and the seeding hopper 53 is controlled to discharge material for sowing. After sowing is completed, the sensor switch 525 on the seeding hopper 53 sends information back to control terminal 1, and control terminal 1 sends information back to drive source 523. Drive source 523 is turned off, and the seeding hopper 53 does not discharge seeds. At the same time, a signal is sent to the water and fertilizer structure 54 through control terminal 1, so that the water and fertilizer structure 54 waters the seeds. As one end of the propagation frame 42 enters the discharge end of the topsoil covering structure 55, signals are transmitted sequentially through the sensor switch 525 on the topsoil covering structure 55, control terminal 1, and drive source 523 on the topsoil covering structure 55, and the topsoil covering structure 55 is controlled to discharge material to cover the seeds. After the soil covering is completed, the sensor switch 525 on the topsoil covering structure 55 sends information back to control terminal 1, and control terminal 1 sends information back to drive source 523. Drive source 523 is turned off, and the topsoil covering structure 55 does not discharge soil. After sowing is completed, the breeding frame 42 rotates along the closed-loop tray delivery chain 411.

[0085] When the metering sensor 526 inside the soil filling structure 52 and the topsoil covering structure 55 detects that the amount of material inside is less than the preset amount, it sends a message to the control terminal 1. The control terminal 1 then sends a start command to the soil conveyor 56. After the soil conveyor 56 starts, as the conveyor belt rotates, the end near the ground carries the soil accumulated on the ground to the storage trough 562 through the adjacent baffle 561. When it is moved to the area above the connection between the soil filling structure 52 and the topsoil covering structure 55, the soil in the storage trough 562 falls into the soil filling structure 52 and the topsoil covering structure 55 with the rotation of the conveyor belt, completing the soil replenishment work. Because the discharge end of the soil conveyor 56 is parallel to the connection between the soil filling structure 52 and the topsoil covering structure 55, most of the soil in the storage trough 562 falls into the soil filling structure 52 during the falling process, and a small portion falls into the topsoil covering structure 55, thus meeting the replenishment needs of the soil filling structure 52 and the topsoil covering structure 55.

[0086] Specifically, when it is necessary to control the discharge volume of the soil adding structure 52, the seeding hopper 53 and the topsoil covering structure 55, it is only necessary to adjust the height of the bolt 5225 in the receiving groove 5222 so that the lifting plate 5224 abuts against the drive source 523 and moves up or down, thereby achieving the height of the rolling drum 524.

[0087] Specifically, the sowing time, sowing speed, and number of sowing rows of the sowing hopper 53 can all be preset in advance.

[0088] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
